Valhalla's Things: Elastic Neck Top Two: MOAR Ruffles

Posted on March 9, 2024
Tags: madeof:atoms, craft:sewing, FreeSoftWear
A woman wearing a white top with a wide neck with ruffles and puffy sleeves that are gathered at the cuff. The top is tucked in the trousers to gather the fullness at the waist. After making my Elastic Neck Top I knew I wanted to make another one less constrained by the amount of available fabric. I had a big cut of white cotton voile, I bought some more swimsuit elastic, and I also had a spool of n 100 sewing cotton, but then I postponed the project for a while I was working on other things. Then FOSDEM 2024 arrived, I was going to remote it, and I was working on my Augusta Stays, but I knew that in the middle of FOSDEM I risked getting to the stage where I needed to leave the computer to try the stays on: not something really compatible with the frenetic pace of a FOSDEM weekend, even one spent at home. I needed a backup project1, and this was perfect: I already had everything I needed, the pattern and instructions were already on my site (so I didn t need to take pictures while working), and it was mostly a lot of straight seams, perfect while watching conference videos. So, on the Friday before FOSDEM I cut all of the pieces, then spent three quarters of FOSDEM on the stays, and when I reached the point where I needed to stop for a fit test I started on the top. Like the first one, everything was sewn by hand, and one week after I had started everything was assembled, except for the casings for the elastic at the neck and cuffs, which required about 10 km of sewing, and even if it was just a running stitch it made me want to reconsider my lifestyle choices a few times: there was really no reason for me not to do just those seams by machine in a few minutes. Instead I kept sewing by hand whenever I had time for it, and on the next weekend it was ready. We had a rare day of sun during the weekend, so I wore my thermal underwear, some other layer, a scarf around my neck, and went outside with my SO to have a batch of pictures taken (those in the jeans posts, and others for a post I haven t written yet. Have I mentioned I have a backlog?). And then the top went into the wardrobe, and it will come out again when the weather will be a bit warmer. Or maybe it will be used under the Augusta Stays, since I don t have a 1700 chemise yet, but that requires actually finishing them. The pattern for this project was already online, of course, but I ve added a picture of the casing to the relevant section, and everything is as usual #FreeSoftWear.

  1. yes, I could have worked on some knitting WIP, but lately I m more in a sewing mood.

Valhalla's Things: Denim Waistcoat

Posted on March 8, 2024
Tags: madeof:atoms, craft:sewing, FreeSoftWear
A woman wearing a single breasted waistcoat with double darts at the waist, two pocket flaps at the waist and one on the left upper breast. It has four jeans buttons. I had finished sewing my jeans, I had a scant 50 cm of elastic denim left. Unrelated to that, I had just finished drafting a vest with Valentina, after the Cutters Practical Guide to the Cutting of Ladies Garments. A new pattern requires a (wearable) mockup. 50 cm of leftover fabric require a quick project. The decision didn t take a lot of time. As a mockup, I kept things easy: single layer with no lining, some edges finished with a topstitched hem and some with bias tape, and plain tape on the fronts, to give more support to the buttons and buttonholes. I did add pockets: not real welt ones (too much effort on denim), but simple slits covered by flaps. a rectangle of pocketing fabric on the wrong side of a denim
piece; there is a slit in the middle that has been finished with topstitching.
To do them I marked the slits, then I cut two rectangles of pocketing fabric that should have been as wide as the slit + 1.5 cm (width of the pocket) + 3 cm (allowances) and twice the sum of as tall as I wanted the pocket to be plus 1 cm (space above the slit) + 1.5 cm (allowances). Then I put the rectangle on the right side of the denim, aligned so that the top edge was 2.5 cm above the slit, sewed 2 mm from the slit, cut, turned the pocketing to the wrong side, pressed and topstitched 2 mm from the fold to finish the slit. a piece of pocketing fabric folded in half and sewn on all 3
other sides; it does not lay flat on the right side of the fabric because the finished slit (hidden in the picture) is pulling it.
Then I turned the pocketing back to the right side, folded it in half, sewed the side and top seams with a small allowance, pressed and turned it again to the wrong side, where I sewed the seams again to make a french seam. And finally, a simple rectangular denim flap was topstitched to the front, covering the slits. I wasn t as precise as I should have been and the pockets aren t exactly the right size, but they will do to see if I got the positions right (I think that the breast one should be a cm or so lower, the waist ones are fine), and of course they are tiny, but that s to be expected from a waistcoat. The back of the waistcoat, The other thing that wasn t exactly as expected is the back: the pattern splits the bottom part of the back to give it sufficient spring over the hips . The book is probably published in 1892, but I had already found when drafting the foundation skirt that its idea of hips includes a bit of structure. The enough steel to carry a book or a cup of tea kind of structure. I should have expected a lot of spring, and indeed that s what I got. To fit the bottom part of the back on the limited amount of fabric I had to piece it, and I suspect that the flat felled seam in the center is helping it sticking out; I don t think it s exactly bad, but it is a peculiar look. Also, I had to cut the back on the fold, rather than having a seam in the middle and the grain on a different angle. Anyway, my next waistcoat project is going to have a linen-cotton lining and silk fashion fabric, and I d say that the pattern is good enough that I can do a few small fixes and cut it directly in the lining, using it as a second mockup. As for the wrinkles, there is quite a bit, but it looks something that will be solved by a bit of lightweight boning in the side seams and in the front; it will be seen in the second mockup and the finished waistcoat. As for this one, it s definitely going to get some wear as is, in casual contexts. Except. Well, it s a denim waistcoat, right? With a very different cut from the get a denim jacket and rip out the sleeves , but still a denim waistcoat, right? The kind that you cover in patches, right? Outline of a sewing machine with teeth and crossed bones below it, and the text  home sewing is killing fashion / and it's illegal And I may have screenprinted a home sewing is killing fashion patch some time ago, using the SVG from wikimedia commons / the Home Taping is Killing Music page. And. Maybe I ll wait until I have finished the real waistcoat. But I suspect that one, and other sewing / costuming patches may happen in the future. No regrets, as the words on my seam ripper pin say, right? :D

Valhalla's Things: Jeans, step two. And three. And four.

A woman wearing a regular pair of slim-cut black denim jeans. I was working on what looked like a good pattern for a pair of jeans-shaped trousers, and I knew I wasn t happy with 200-ish g/m cotton-linen for general use outside of deep summer, but I didn t have a source for proper denim either (I had been low-key looking for it for a long time). Then one day I looked at an article I had saved about fabric shops that sell technical fabric and while window-shopping on one I found that they had a decent selection of denim in a decent weight. I decided it was a sign, and decided to buy the two heaviest denim they had: a 100% cotton, 355 g/m one and a 97% cotton, 3% elastane at 385 g/m 1; the latter was a bit of compromise as I shouldn t really be buying fabric adulterated with the Scourge of Humanity, but it was heavier than the plain one, and I may be having a thing for tightly fitting jeans, so this may be one of the very few woven fabric where I m not morally opposed to its existence. And, I d like to add, I resisted buying any of the very nice wools they also seem to carry, other than just a couple of samples. Since the shop only sold in 1 meter increments, and I needed about 1.5 meters for each pair of jeans, I decided to buy 3 meters per type, and have enough to make a total of four pair of jeans. A bit more than I strictly needed, maybe, but I was completely out of wearable day-to-day trousers. a cardboard box with neatly folded black denim, covered in semi-transparent plastic. The shop sent everything very quickly, the courier took their time (oh, well) but eventually delivered my fabric on a sunny enough day that I could wash it and start as soon as possible on the first pair. The pattern I did in linen was a bit too fitting, but I was afraid I had widened it a bit too much, so I did the first pair in the 100% cotton denim. Sewing them took me about a week of early mornings and late afternoons, excluding the weekend, and my worries proved false: they were mostly just fine. The only bit that could have been a bit better is the waistband, which is a tiny bit too wide on the back: it s designed to be so for comfort, but the next time I should pull the elastic a bit more, so that it stays closer to the body. The same from the back, showing the applied pockets with a sewn logo. I wore those jeans daily for the rest of the week, and confirmed that they were indeed comfortable and the pattern was ok, so on the next Monday I started to cut the elastic denim. I decided to cut and sew two pairs, assembly-line style, using the shaped waistband for one of them and the straight one for the other one. I started working on them on a Monday, and on that week I had a couple of days when I just couldn t, plus I completely skipped sewing on the weekend, but on Tuesday the next week one pair was ready and could be worn, and the other one only needed small finishes. A woman wearing another pair of jeans; the waistband here is shaped to fit rather than having elastic. And I have to say, I m really, really happy with the ones with a shaped waistband in elastic denim, as they fit even better than the ones with a straight waistband gathered with elastic. Cutting it requires more fabric, but I think it s definitely worth it. But it will be a problem for a later time: right now three pairs of jeans are a good number to keep in rotation, and I hope I won t have to sew jeans for myself for quite some time. A plastic bag with mid-sized offcuts of denim; there is a 30 cm ruler on top that is just wider than the bag I think that the leftovers of plain denim will be used for a skirt or something else, and as for the leftovers of elastic denim, well, there aren t a lot left, but what else I did with them is the topic for another post. Thanks to the fact that they are all slightly different, I ve started to keep track of the times when I wash each pair, and hopefully I will be able to see whether the elastic denim is significantly less durable than the regular, or the added weight compensates for it somewhat. I m not sure I ll manage to remember about saving the data until they get worn, but if I do it will be interesting to know. Oh, and I say I ve finished working on jeans and everything, but I still haven t sewn the belt loops to the third pair. And I m currently wearing them. It s a sewist tradition, or something. :D

Valhalla's Things: Jeans, step one

CW for body size change mentions A woman wearing a pair of tight jeans. Just like the corset, I also needed a new pair of jeans. Back when my body size changed drastically of course my jeans no longer fit. While I was waiting for my size to stabilize I kept wearing them with a somewhat tight belt, but it was ugly and somewhat uncomfortable. When I had stopped changing a lot I tried to buy new ones in the same model, and found out that I was too thin for the menswear jeans of that shop. I could have gone back to wearing women s jeans, but I didn t want to have to deal with the crappy fabric and short pockets, so I basically spent a few years wearing mostly skirts, and oversized jeans when I really needed trousers. Meanwhile, I had drafted a jeans pattern for my SO, which we had planned to make in technical fabric, but ended up being made in a cotton-wool mystery mix for winter and in linen-cotton for summer, and the technical fabric version was no longer needed (yay for natural fibres!) It was clear what the solution to my jeans problems would have been, I just had to stop getting distracted by other projects and draft a new pattern using a womanswear block instead of a menswear one. Which, in January 2024 I finally did, and I believe it took a bit less time than the previous one, even if it had all of the same fiddly pieces. I already had a cut of the same cotton-linen I had used for my SO, except in black, and used it to make the pair this post is about. The parametric pattern is of course online, as #FreeSoftWear, at the usual place. This time it was faster, since I didn t have to write step-by-step instructions, as they are exactly the same as the other pattern. Same as above, from the back, with the crotch seam pulling a bit. A faint decoration can be seen on the pockets, with the line art version of the logo seen on this blog. Making also went smoothly, and the result was fitting. Very fitting. A big too fitting, and the standard bum adjustment of the back was just enough for what apparently still qualifies as a big bum, so I adjusted the pattern to be able to add a custom amount of ease in a few places. But at least I had a pair of jeans-shaped trousers that fit! Except, at 200 g/m I can t say that fabric is the proper weight for a pair of trousers, and I may have looked around online1 for some denim, and, well, it s 2024, so my no-fabric-buy 2023 has not been broken, right? Let us just say that there may be other jeans-related posts in the near future.

  1. I had already asked years ago for denim at my local fabric shops, but they don t have the proper, sturdy, type I was looking for.

Valhalla's Things: A Corset or Two

Posted on January 7, 2024
Tags: madeof:atoms, craft:sewing, period:victorian, FreeSoftWear
a black coutil midbust corset, from a 3/4 front view, showing the busk closure, a waist tape and external boning channels made of the same twill tape and placed about 1-2 cm from each other at waist level. CW for body size change mentions I needed a corset, badly. Years ago I had a chance to have my measurements taken by a former professional corset maker and then a lesson in how to draft an underbust corset, and that lead to me learning how nice wearing a well-fitted corset feels. Later I tried to extend that pattern up for a midbust corset, with success. And then my body changed suddenly, and I was no longer able to wear either of those, and after a while I started missing them. Since my body was still changing (if no longer drastically so), and I didn t want to use expensive materials for something that had a risk of not fitting after too little time, I decided to start by making myself a summer lightweight corset in aida cloth and plastic boning (for which I had already bought materials). It fitted, but not as well as the first two ones, and I ve worn it quite a bit. I still wanted back the feeling of wearing a comfy, heavy contraption of coutil and steel, however. After a lot of procrastination I redrafted a new pattern, scrapped everything, tried again, had my measurements taken by a dressmaker [#dressmaker], put them in the draft, cut a first mock-up in cheap cotton, fixed the position of a seam, did a second mock-up in denim [#jeans] from an old pair of jeans, and then cut into the cheap herringbone coutil I was planning to use. And that s when I went to see which one of the busks in my stash would work, and realized that I had used a wrong vertical measurement and the front of the corset was way too long for a midbust corset. a corset busk basted to a mock-up with scraps of fabric between each stud / loop. Luckily I also had a few longer busks, I basted one to the denim mock up and tried to wear it for a few hours, to see if it was too long to be comfortable. It was just a bit, on the bottom, which could be easily fixed with the Power Tools1. Except, the more I looked at it the more doing this felt wrong: what I needed most was a midbust corset, not an overbust one, which is what this was starting to be. I could have trimmed it down, but I knew that I also wanted this corset to be a wearable mockup for the pattern, to refine it and have it available for more corsets. And I still had more than half of the cheap coutil I was using, so I decided to redo the pattern and cut new panels. And this is where the or two comes in: I m not going to waste the overbust panels: I had been wanting to learn some techniques to make corsets with a fashion fabric layer, rather than just a single layer of coutil, and this looks like an excellent opportunity for that, together with a piece of purple silk that I know I have in the stash. This will happen later, however, first I m giving priority to the underbust. Anyway, a second set of panels was cut, all the seam lines marked with tailor tacks, and I started sewing by inserting the busk. And then realized that the pre-made boning channel tape I had was too narrow for the 10 mm spiral steel I had plenty of. And that the 25 mm twill tape was also too narrow for a double boning channel. On the other hand, the 18 mm twill tape I had used for the waist tape was good for a single channel, so I decided to put a single bone on each seam, and then add another piece of boning in the middle of each panel. Since I m making external channels, making them in self fabric would have probably looked better, but I no longer had enough fabric, because of the cutting mishap, and anyway this is going to be a strictly underwear only corset, so it s not a big deal. Once the boning channel situation was taken care of, everything else proceeded quite smoothly and I was able to finish the corset during the Christmas break, enlisting again my SO to take care of the flat steel boning while I cut the spiral steels myself with wire cutters. The same corset straight from the front: the left side is a few mm longer than the right side I could have been a bit more precise with the binding, as it doesn t align precisely at the front edge, but then again, it s underwear, nobody other than me and everybody who reads this post is going to see it and I was in a hurry to see it finished. I will be more careful with the next one. The same corset from the back, showing cross lacing with bunny ears at the waist and a lacing gap of about 8 cm. I also think that I haven t been careful enough when pressing the seams and applying the tape, and I ve lost about a cm of width per part, so I m using a lacing gap that is a bit wider than I planned for, but that may change as the corset gets worn, and is still within tolerance. Also, on the morning after I had finished the corset I woke up and realized that I had forgotten to add garter tabs at the bottom edge. I don t know whether I will ever use them, but I wanted the option, so maybe I ll try to add them later on, especially if I can do it without undoing the binding. The next step would have been flossing, which I proceeded to postpone until I ve worn the corset for a while: not because there is any reason for it, but because I still don t know how I want to do it :) What was left was finishing and uploading the pattern and instructions, that are now on my sewing pattern website as #FreeSoftWear, and finally I could post this on the blog.

  1. i.e. by asking my SO to cut and sand it, because I m lazy and I hate doing that part :D

Valhalla's Things: Random Sashiko + Crazy Quilt Pocket

Posted on January 5, 2024
Tags: madeof:atoms
A 18th century pocket in black jeans with a random pattern of pink running stitches forming squares and other shapes. The unfinished edges of the pieces of jeans can be seen, running more or less diagonally. Lately I ve seen people on the internet talking about victorian crazy quilting. Years ago I had watched a Numberphile video about Hitomezashi Stitch Patterns based on numbers, words or randomness. Few weeks ago I had cut some fabric piece out of an old pair of jeans and I had a lot of scraps that were too small to do anything useful on their own. It easy to see where this can go, right? The wrong side of a pocket piece, showing a light coloured fabric with a grid drawn in pencil, a line of small stitches all around the edges and a mess of thread ends left hanging. I cut a pocket shape out of old garment mockups (this required some piecing), drew a square grid, arranged scraps of jeans to cover the other side, kept everything together with a lot of pins, carefully avoided basting anything, and started covering everything in sashiko / hitomezashi stitches, starting each line with a stitch on the front or the back of the work based on the result of:
import random
random.choice(["front", "back"])
The wrong side of the other pocket piece, with just three lines of stitching and a piece of paper to mark the pattern. There are bits of jeans peeking out of the sides. For the second piece I tried to use a piece of paper with the square grid instead of drawing it on the fabric: it worked, mostly, I would not do it again as removing the paper was more of a hassle than drawing the lines in the first place. I suspected it, but had to try it anyway. The front of the pocket seen from the wrong side, with a machine seam around the lit, whose end has been cut in a triangle so that it can be turned. Then I added a lining from some plain black cotton from the stash; for the slit I put the lining on the front right sides together, sewn at 2 mm from the marked slit, cut it, turned the lining to the back side, pressed and then topstitched as close as possible to the slit from the front. The finished pocket attached to a belt made from the waistband of a pair of jeans (with button, buttonhole and belt loops still attached) whose raw edges (left when unpicking away the jeans) have been sewn shut by hand. I bound everything with bias tape, adding herringbone tape loops at the top to hang it from a belt (such as one made from the waistband of one of the donor pair of jeans) and that was it. The back of the pocket, showing another random pattern in two different shades of pink for the vertical and horizontal lines of stitching. I like the way the result feels; maybe it s a bit too stiff for a pocket, but I can see it work very well for a bigger bag, and maybe even a jacket or some other outer garment.

Jonathan Dowland: Interzone's new home

IZ #294, the latest issue IZ #294, the latest issue
The long running British1 SF Magazine Interzone has a new home and new editor, Gareth Jelley, starting with issue 294. It's also got a swanky new format ("JB6"): a perfect-bound, paperback novel size, perfect for fitting into an oversize coat or jeans pocket for reading on the train. I started reading Interzone in around 2003, having picked up an issue (#176) from Feb 2002 that was languishing on the shelves in Forbidden Planet. Once I discovered it I wondered why it had taken me so long. That issue introduced me to Greg Egan. I bought a number of back issues on eBay, to grab issues with stories by people including Terry Pratchett, Iain Banks, Alastair Reynolds, and others.
IZ #194: The first by TTA press IZ #194: The first by TTA press
A short while later in early 2004, after 22 years, Interzone's owner and editorship changed from David Pringle to Andy Cox and TTA Press. I can remember the initial transition was very jarring: the cover emphasised expanding into coverage of Manga, Graphic Novels and Video Games (which ultimately didn't happen) but after a short period of experimentation it quickly settled down into a similarly fantastic read. I particularly liked the move to a smaller, perfect-bound form-factor in 2012. I had to double-check this but I'd been reading IZ throughout the TTA era and it lasted 18 years! Throughout that time I have discovered countless fantastic authors that I would otherwise never have experienced. Some (but by no means all) are Dominic Green, Daniel Kaysen, Chris Beckett, C cile Cristofari, Aliya Whiteley, Tim Major, Fran oise Harvey, Will McIntosh. Cox has now retired (after 100 issues and a tenure almost as long as Pringle) and handed the reins to Gareth Jelley/MYY Press, who have published their first issue, #294. Jelley is clearly putting a huge amount of effort into revitalizing the magazine. There's a new homepage at interzone.press but also companion internet presences: a plethora of digital content at interzone.digital, Interzone Socials (a novel idea), a Discord server, a podcast, and no doubt more. Having said that, the economics of small magazines have been perilous for a long time, and that hasn't changed, so I think the future of IZ (in physical format at least) is in peril. If you enjoy short fiction, fresh ideas, SF/F/Fantastika; why not try a subscription to Interzone, whilst you still can!

  1. Interzone has always been "British", in some sense, but never exclusively so. I recall fondly a long-term project under Pringle to publish a lot of Serbian writer Zoran ivkovi , for example, and the very first story I read was by Australian Greg Egan. Under Jelley, the magazine is being printed in Poland and priced in Euros. I expect it to continue to attract and publish writers from all over the place.

Louis-Philippe V ronneau: Montreal's Debian & Stuff - October 2022

Our local Debian user group gathered on Sunday October 30th to chat, work on Debian and do other, non-Debian related hacking :) This time around, we met at EfficiOS's1 offices. As you can see from the following picture, it's a great place and the view they have is pretty awesome. Many thanks for hosting us! The view from EfficiOS' offices, overlooking the Mont-Royal This was our 4th meeting this year and once again, attendance was great: 10 people showed up to work on various things. Following our bi-monthly schedule, our next meeting should be in December, but I'm not sure it'll happen. December can be a busy month here and I will have to poke our mailing list to see if people have the spoons for an event. This time around, I was able to get a rough log of the Debian work people did: pollo: mjeanson: viashimo: lavamind: anarcat: babelouest: tvaz: As always, thanks to the Debian project for granting us a budget to buy some food!

Jonathan Dowland: Broken webcam aspect ratio

picture of my Sony RX100-III camera Sony RX100-III, relegated to a webcam
Sometimes I have remote meetings with Google Meet. Unlike the other video-conferencing services that I use (Bluejeans, Zoom), my video was stretched out of proportion under Google Meet with Firefox. I haven't found out why this was happening, but I did figure out a work-around. Thanks to Daniel Silverstone, Rob Kendrick, Gregor Herrmann and Ben Allen for pointing me in the right direction! Hardware The lovely Sony RX-100 mk3 that I bought in 2015 has spent most of its life languishing unused. During the Pandemic, once I was working from home all the time, I decided to press-gang it into service as a better-quality webcam. Newer models of this camera the mark 4 onwards have support for a USB mode called "PC Remote", which effectively makes them into webcams. Unfortunately my mark 3 does not support this, but it does have HDMI out, so I picked up a cheap "HDMI to USB Video Capture Card" from eBay. Video modes
Before: wrong aspect ratio Before: wrong aspect ratio
This device offers a selection of different video modes over a webcam interface. I used qv4l2 to explore the different modes. It became clear that the camera was outputting a signal at 16:9, but the modes on offer from the dongle were for a range of different aspect ratios. The picture for these other ratios was not letter or pillar-boxed, but stretched to fit. I also noticed that the modes which had the correct aspect ratio were at very low framerates: 1920x1080@5fps, 1360x768@8fps, 1280x720@10fps. It felt to me that I would look unnatural at such a low framerate. The most promising mode was close to the right ratio, 720x480 and 30 fps. Software
After: corrected aspect ratio After: corrected aspect ratio
My initial solution is to use the v4l2loopback kernel module, which provides a virtual loop-back webcam interface. I can write video data to it from one process, and read it back from another. Loading it as follows:
modprobe v4l2loopback exclusive_caps=1
The option exclusive_caps configures the module into a mode where it initially presents a write-only interface, but once a process has opened a file handle, it then switches to read-only for subsequent processes. Assuming there are no other camera devices connected at the time of loading the module, it will create /dev/video0.1 I experimented briefly with OBS Studio, the very versatile and feature-full streaming tool, which confirmed that I could use filters on the source video to fix the aspect ratio, and emit the result to the virtual device. I don't otherwise use OBS, though, so I achieve the same result using ffmpeg:
fmpeg -s 720x480 -i /dev/video1 -r 30 -f v4l2 -vcodec rawvideo \
    -pix_fmt yuyv422 -s 720x405 /dev/video0
The source options are to select the source video mode I want. The codec and pixel formats are to match what is being emitted (I determined that using ffprobe on the camera device). The resizing is triggered by supplying a different size to the -s parameter. I think that is equivalent to explicitly selecting a "scale" filter, and there might be other filters that could be used instead (to add pillar boxes for example). This worked just as well. In Google Meet, I select the Virtual Camera, and Google Meet is presented with only one video mode, in the correct aspect ratio, and no configurable options for it, so it can't misbehave. Future I'm planning to automate the loading (and unloading) of the module and starting the ffmpeg process in response to the real camera device being plugged or unplugged, using systemd events and services. (I don't leave the camera plugged in all the time due to some bad USB behaviour I've experienced if I do so.) If I get that working, I will write a follow-up.

  1. you can request a specific device name/number with another module option.

Jonathan Dowland: ereader

Kobo Libra H2O e-reader Kobo Libra H2O e-reader
This year I finally bought an e-reader: a "Kobo Libra H2O": a 7" 300ppi screen with an adjustable colour temperature front light, waterproof, physical buttons on a "margin"/spine which pushes the case dimensions up to 8", which is sadly a little too big for most jeans pockets. In fact this is the second time I've bought one. Sarah and I bought a pair of Amazon Kindle Paperwhite (2nd generation) readers as Honeymoon gifts for each other in 2013. Sarah took to hers, but after giving mine a try and reading a couple of books on it I ended up giving it to my Father-in-law. The main problem I had with it was the colour temperature of the backlight: it was too blue and "clinical". It's interesting to me to realise how the environment that I read in can become indelibly linked to the memory of that book. One book in particular that I read on the Kindle was James Smythe's "The Machine", a modern twist on a classic horror story. This was perfectly complemented by the somewhat pallid, sick colour of the backlight, especially on its lowest brightness settings. It didn't go so well with other stories.
Broken Libra H2O e-reader Broken Libra H2O e-reader
I got on much better with the Libra H2O. For me, e-books and e-reading has not replaced traditional paper books, but complemented them, giving me an opportunity to read in contexts and situations where I couldn't manage with a real book (such as in the pitch black, lying on my back with a toddler on my chest). I feel that being able to read more often thanks to the e-reader has spurred me on to read even paper books more frequently as well. Unfortunately the screen broke, about 10 months after I bought it! After a bit of soul-searching on what to do about replacing it, and briefly considering the latest Amazon Paperwhite (which now has a 300ppi display and adjustable-colour temperature front-light). This looks like a very nice e-reader: no physical buttons which is a bit of a shame but narrower without the margin/spine of the Kobo, so possibly more pocket-friendly. On the other hand, I really felt that I wanted to avoid giving Amazon the money, for a whole variety of reasons.
Libra 2 e-reader. Spot the difference? Libra 2 e-reader. Spot the difference?
So I instead settled on the "Kobo Libra 2", which is a slight refresh of the Libra H2O, but almost identical. I'm going to pair it with a nice cover for when its not in use and hopefully it will last longer than its predecessor. My current favourite feature on the Libra 2, that I don't remember on the H2O and I'm fairly sure doesn't exist on Kindles is it supports a "night mode", which is effectively a reverse video, white-on-black mode. This is fantastic for keeping the light levels down at night. I was already using the backlight at about 2% brightness and occasionally found even that too bright.

Russell Coker: USB Cables and Cameras

This page has summaries of some USB limits [1]. USB 2.0 has the longest cable segment limit of 5M (1.x, 3.x, and USB-C are all shorter), so USB 2.0 is what you want for long runs. The USB limit for daisy chained devices is 7 (including host and device), so that means a maximum of 5 hubs or a total distance between PC and device of 30M. There are lots of other ways of getting longer distances, the cheapest seems to be putting an old PC at the far end of an Ethernet cable. Some (many? most?) laptops have USB for the interface to the built in camera, and these are sold from scrapped laptops. You could probably setup a home monitoring system in a typical home by having a centrally located PC with USB hubs fanning out to the corners. But old Android phones on a Wifi network seems like an easier option if you can prevent the phones from crashing all the time.

Shirish Agarwal: Trains, Planes and the future

Swacch Bharat - Indian Railways Copyright: Indian Express

Swacch Bharat Indian Railways Copyright: Indian Express

Some of the content may be NSFW. viewer discretion advised. I have had a life-long fascination with trains. One of my first memories was that of 5-7 year old, clutching my mother or grandmother s hand seeing the steam engine lumbering down whistling and smoking at the same time. I was both afraid and strangely drawn to the iron beast and the first time I knew and then slowly understood that if we come with luggage and the steam-engine comes, it means we are going to travel. I have travelled some, but there are lots to explore still and I do hope that I cover some more of it during my lifetime. The reason I am writing about trains is an article which caught my eye couple of days. Besides seeing the changing geography, the variety of food one can get on train and in stations is one of the primary reasons that Indians love to travel by trains. It is one place where you could have incredible conversations over cup of tea or favourite food and unlike air travel and the famed IFE (In-flight entertainment) people are actually pretty social even with all the gadgets. For those who are wondering, the author was travelling between Jamshedpur, Gujarat to Kolkatta, a train ride which has now gone on my bucket list for the delectable items the author has described To add to the above, it is still cheaper than air travel, although that is changing a bit as Indian Railways seeks to modernize Railways and make it into world-class bullet trains. Indian Railways has a long, rich culture and some of the most interesting nuggets you learn over time adds to the fascination of the Railways. For instance I m sharing this letter which I read first in book and then saw in the New Delhi Railway Museum. The letter I am sharing below was written by a certain Shri Okhil Chandra Sen to the Sahibganj Railway Office in year 1909, almost 38 years before India became independent. I am arrive by passenger train Ahmedpur station and my belly is too much swelling with jackfruit. I am therefore went to privy. Just I doing the nuisance that guard making whistle blow for train to go off and I am running with lotah in one hand and dhoti in the next when I am fall over and expose all my shocking to man and female women on plateform. I am got leaved at Ahmedpur station. This too much bad, if passenger go to make dung that dam guard not wait train five minutes for him. I am therefore pray your honour to make big fine on that guard for public sake. Otherwise I am making big report! to papers. If it were not for Mr. Okhil Chandra Sen we would still be running with water bottle (improvement) and jeans/shorts/whatever (again improvement) while the possibility of falling over would always be omnipresent in a hurry. Now we do have toilets and some of the better trains even have Bio-toilets which should make things better as well.(/NSFW) For the plane bit, most of my flights have been domestic flying. Some of my most memorable flights is when flying from Mumbai on a clear sky overlooking the Queen s necklace, loving it and landing in Bangalore during mist or rain or both. Delhi is also good as airports go but nothing much adventurous about it. It was only with the experience of my first international flight, I realized the same feeling again, nervousness and sense of adventure as you meet new people. Nowadays every week I do try and broaden my horizon by seeking and learning a bit about International Travel.

In this I came across an article on National Geographic site which also evoked similar feelings. While I can t go back to the past and even if I did (in distant past before I was born), I wouldn t want to improve my financial situation at all (as otherwise I would hit the Grandfather Paradox or/and the Butterfly effect (essentially saying there s no free lunch), it still makes you wonder about a time when people had lot more adventure and lot more moving parts. I do wish they had a much bigger snapshot of that plane so I could really see how people sat in the old aircraft. The low-resolution picture doesn t do justice to the poster and the idea of that time. https://en.wikipedia.org/wiki/A_Sound_of_Thunder for an implementation of Butterfly effect. The Grandfather Paradox has been seen plenty of times in fantasy movies like the Back to the Future, Planet of the Apes and many others so will not go there. For the average joe today, s/he has to navigate security,check bags, get her/imself processed through passport control, get boarding pass, get to the gate on-time, get to the aircraft via bridge or bus, get to the seat, somehow make it through the ascent and use your IFE and get snacks and meals till it s time to touch-down and re-do the whole drill again as many times you are connecting. I really admire Gunnar Wolf for the tenacity he showed for the x number of connections he made both ways.
The world's 10 best airports Copyright: Changi International Airport

While leafing through the interweb today, came across an article . While you can slice and dice the report anyway you want, for me if ever I get a chance again for an International Travel, I would try to see I get a layover at these three airports in order of preference (this is on the basis that none of these airports need a transit visa for the activities shared) a. Changi International Airport It is supposed to have shower amenities, has a movie theatre (+1), free tour of the city (+1) and of course as many Indians do go to Singapore as a destination in itself would have multiple vegetarian options (+2) so would be nice if I need to layover. b. Zurich Airport (ZRH) For passengers with an extended layover, Zurich Airport offers bicycle and inline-skate rentals and excursions to the Swiss Museum of Transport Lucerne. From business-insider.com. While I m not much of a bicycle and inline-skating freak, if the Swiss Museum of Transport Lucerne is anything to the scale of Isiko Museum which I shared in a blog post sometime before, it would be worth by itself. I haven t tried to find the site but can imagine, for e.g. if it has a full-scale model of a submarine or train engine, either steam-engines or ones like SNCF or any of the other bullet-trains and early aircraft, it would just blow my mind. When you are talking about transport, there is so much science, business, logistics etc. that I m sure I ll overload with information, photos and any trinkets they have to buy. c. Central Japan International Airport (NGO) It has a 1,000-foot-long sky deck where passengers can watch ships sail into Nagoya Port. There s also a traditional Japanese bathhouse where you can have a relaxing soak while watching the sunset over the bay. BusinessInsider.com Not a bad place to be if you need a layover. Just sink yourself in the bathhouse and see the bay and ships coming in. Luxury indeed. Honourable mention d. Munich Airport (MUC) A nearby visitors park features mini golf and a display of historic aircraft. Business-Insider.com . Now this would have made my list but I guess one would need a Schengen visa to access the visitors park but then if you have that, then why just stay in the Airport itself, could travel through Europe itself and have a longish stop-over. So all in all, it s indeed a fascinating time to be alive, dreaming and just being. Till later. Update I had forgotten to share one more reason why I was writing this article. Although somewhat of a cynic, am hopeful that Pune metro happens. Also, if I had just waited a day, would have been able to add couple of wonderful articles that would make people wanderlust more

Iustin Pop: Energy bar restored!

So, I've been sick. Quite sick, as for the past ~2 weeks I wasn't able to bike, run, work or do much beside watch movies, look at photos and play some light games (ARPGs rule in this case, all you need to do is keep the left mouse button pressed). It was supposed to be only a light viral infection, but it took longer to clear out than I expected, probably due to it happening right after my dental procedure (and possibly me wanting to restart exercise too soon, to fast). Not fun, it felt like the thing that refills your energy/mana bar in games broke. I simply didn't feel restored, despite sleeping a lot; 2-3 naps per day sound good as long as they are restorative, if they're not, sleeping is just a chore. The funny thing is that recovery happened so slow, that when I finally had energy it took me by surprise. It was like oh, wait, I can actually stand and walk without feeling dizzy! Wohoo! As such, yesterday was a glorious Saturday I was therefore able to walk a bit outside the house this weekend and feel like having a normal cold, not like being under a cursed: -4 vitality spell. I expect the final symptoms to clear out soon, and that I can very slowly start doing some light exercise again. Not tomorrow, though In the meantime, I'm sharing a picture from earlier this year that I found while looking through my stash. Was walking in the forest in Pontresina on a beatiful sunny day, when a sudden gust of wind caused a lot of the snow on the trees to fly around and make it look a bit magical (photo is unprocessed beside conversion from raw to jpeg, this is how it was straight out of the camera): Winter in the forest Why a winter photo? Because that's exactly how cold I felt the previous weekend: 30 C outside, but I was going to the doctor in jeans and hoodie and cap, shivering

Norbert Preining: Ian Buruma: Wages of Guilt

Since moving to Japan, I got more and more interested in history, especially the recent history of the 20th century. The book I just finished, Ian Buruma (Wiki, home page) Wages of Guilt Memories of War in Germany and Japan (Independent, NYRB), has been a revelation for me. As an Austrian living in Japan, I am experiencing the discrepancy between these two countries with respect to their treatment of war legacy practically daily, and many of my blog entries revolve around the topic of Japanese non-reconciliation.
Willy Brandt went down on his knees in the Warsaw ghetto, after a functioning democracy had been established in the Federal Republic of Germany, not before. But Japan, shielded from the evil world, has grown into an Oskar Matzerath: opportunistic, stunted, and haunted by demons, which it tries to ignore by burying them in the sand, like Oskar s drum.
Ian Buruma, Wages of Guilt, Clearing Up the Ruins
Buruma-Wages_of_Guilt The comparison of Germany and Japan with respect to their recent history as laid out in Buruma s book throws a spotlight on various aspects of the psychology of German and Japanese population, while at the same time not falling into the easy trap of explaining everything with difference in the guilt culture. A book of great depth and broad insights everyone having even the slightest interest in these topics should read.
This difference between (West) German and Japanese textbooks is not just a matter of detail; it shows a gap in perception.
Ian Buruma, Wages of Guilt, Romance of the Ruins
Only thinking about giving a halfway full account of this book is something impossible for me. The sheer amount of information, both on the German and Japanese side, is impressive. His incredible background (studies of Chinese literature and Japanese movie!) and long years as journalist, editor, etc, enriches the book with facets normally not available: In particular his knowledge of both the German and Japanese movie history, and the reflection of history in movies, were complete new aspects for me (see my recent post (in Japanese)). The book is comprised of four parts: The first with the chapters War Against the West and Romance of the Ruins; the second with the chapters Auschwitz, Hiroshima, and Nanking; the third with History on Trial, Textbook Resistance, and Memorials, Museums, and Monuments; and the last part with A Normal Country, Two Normal Towns, and Clearing Up the Ruins. Let us look at the chapters in turn: The boook somehow left me with a bleak impression of Japanese post-war times as well as Japanese future. Having read other books about the political ignorance in Japan (Norma Field s In the realm of a dying emperor, or the Chibana history), Buruma s characterization of Japanese politics is striking. He couldn t foresee the recent changes in legislation pushed through by the Abe government actually breaking the constitution, or the rewriting of history currently going on with respect to comfort women and Nanking. But reading his statement about Article Nine of the constitution and looking at the changes in political attitude, I am scared about where Japan is heading to:
The Nanking Massacre, for leftists and many liberals too, is the main symbol of Japanese militarism, supported by the imperial (and imperialist) cult. Which is why it is a keystone of postwar pacifism. Article Nine of the constitution is necessary to avoid another Nanking Massacre. The nationalist right takes the opposite view. To restore the true identity of Japan, the emperor must be reinstated as a religious head of state, and Article Nine must be revised to make Japan a legitimate military power again. For this reason, the Nanking Massacre, or any other example of extreme Japanese aggression, has to be ignored, softened, or denied.
Ian Buruma, Wages of Guilt, Nanking
While there are signs of resistance in the streets of Japan (Okinawa and the Hanako bay, the demonstrations against secrecy law and reversion of the constitution), we are still to see a change influenced by the people in a country ruled and distributed by oligarchs. I don t think there will be another Nanking Massacre in the near future, but Buruma s books shows that we are heading back to a nationalistic regime similar to pre-war times, just covered with a democratic veil to distract critics.
I close with several other quotes from the book that caught my attention: In the preface and introduction:
[ ] mainstream conservatives made a deliberate attempt to distract people s attention from war and politics by concentrating on economic growth.
The curious thing was that much of what attracted Japanese to Germany before the war Prussian authoritarianism, romantic nationalism, pseudo-scientific racialism had lingered in Japan while becoming distinctly unfashionable in Germany.
In Romance of the Ruins:
The point of all this is that Ikeda s promise of riches was the final stage of what came to be known as the reverse course, the turn away from a leftist, pacifist, neutral Japan a Japan that would never again be involved in any wars, that would resist any form of imperialism, that had, in short, turned its back for good on its bloody past. The Double Your Incomes policy was a deliberate ploy to draw public attention away from constitutional issues.
In Hiroshima:
The citizens of Hiroshima were indeed victims, primarily of their own military rulers. But when a local group of peace activists petitioned the city of Hiroshima in 1987 to incorporate the history of Japanese aggression into the Peace Memorial Museum, the request was turned down. The petition for an Aggressors Corner was prompted by junior high school students from Osaka, who had embarrassed Peace Museum officials by asking for an explanation about Japanese responsibility for the war.
The history of the war, or indeed any history, is indeed not what the Hiroshima spirit is about. This is why Auschwitz is the only comparison that is officially condoned. Anything else is too controversial, too much part of the flow of history .
In Nanking, by the governmental pseudo-historian Tanaka:
Unlike in Europe or China, writes Tanaka, you won t find one instance of planned, systematic murder in the entire history of Japan. This is because the Japanese have a different sense of values from the Chinese or the Westerners.
In History on Trial:
In 1950, Becker wrote that few things have done more to hinder true historical self-knowledge in Germany than the war crimes trials. He stuck to this belief. Becker must be taken seriously, for he is not a right-wing apologist for the Nazi past, but an eminent liberal.
There never were any Japanese war crimes trials, nor is there a Japanese Ludwigsburg. This is partly because there was no exact equivalent of the Holocaust. Even though the behavior of Japanese troops was often barbarous, and the psychological consequences of State Shinto and emperor worship were frequently as hysterical as Nazism, Japanese atrocities were part of a military campaign, not a planned genocide of a people that included the country s own citizens. And besides, those aspects of the war that were most revolting and furthest removed from actual combat, such as the medical experiments on human guinea pigs (known as logs ) carried out by Unit 731 in Manchuria, were passed over during the Tokyo trial. The knowledge compiled by the doctors of Unit 731 of freezing experiments, injection of deadly diseases, vivisections, among other things was considered so valuable by the Americans in 1945 that the doctors responsible were allowed to go free in exchange for their data.
Some Japanese have suggested that they should have conducted their own war crimes trials. The historian Hata Ikuhiko thought the Japanese leaders should have been tried according to existing Japanese laws, either in military or in civil courts. The Japanese judges, he believed, might well have been more severe than the Allied tribunal in Tokyo. And the consequences would have been healthier. If found guilty, the spirits of the defendants would not have ended up being enshrined at Yasukuni. The Tokyo trial, he said, purified the crimes of the accused and turned them into martyrs. If they had been tried in domestic courts, there is a good chance the real criminals would have been flushed out.
After it was over, the Nippon Times pointed out the flaws of the trial, but added that the Japanese people must ponder over why it is that there has been such a discrepancy between what they thought and what the rest of the world accepted almost as common knowledge. This is at the root of the tragedy which Japan brought upon herself.
Emperor Hirohito was not Hitler; Hitler was no mere Shrine. But the lethal consequences of the emperor-worshipping system of irresponsibilities did emerge during the Tokyo trial. The savagery of Japanese troops was legitimized, if not driven, by an ideology that did not include a Final Solution but was as racialist as Hider s National Socialism. The Japanese were the Asian Herrenvolk, descended from the gods.
Emperor Hirohito, the shadowy figure who changed after the war from navy uniforms to gray suits, was not personally comparable to Hitler, but his psychological role was remarkably similar.
In fact, MacArthur behaved like a traditional Japanese strongman (and was admired for doing so by many Japanese), using the imperial symbol to enhance his own power. As a result, he hurt the chances of a working Japanese democracy and seriously distorted history. For to keep the emperor in place (he could at least have been made to resign), Hirohito s past had to be freed from any blemish; the symbol had to be, so to speak, cleansed from what had been done in its name.
In Memorials, Museums, and Monuments:
If one disregards, for a moment, the differences in style between Shinto and Christianity, the Yasukuni Shrine, with its relics, its sacred ground, its bronze paeans to noble sacrifice, is not so very different from many European memorials after World War I. By and large, World War II memorials in Europe and the United States (though not the Soviet Union) no longer glorify the sacrifice of the fallen soldier. The sacrificial cult and the romantic elevation of war to a higher spiritual plane no longer seemed appropriate after Auschwitz. The Christian knight, bearing the cross of king and country, was not resurrected. But in Japan, where the war was still truly a war (not a Holocaust), and the symbolism still redolent of religious exultation, such shrines as Yasukuni still carry the torch of nineteenth-century nationalism. Hence the image of the nation owing its restoration to the sacrifice of fallen soldiers.
In A Normal Country:
The mayor received a letter from a Shinto priest in which the priest pointed out that it was un-Japanese to demand any more moral responsibility from the emperor than he had already taken. Had the emperor not demonstrated his deep sorrow every year, on the anniversary of Japan s surrender? Besides, he wrote, it was wrong to have spoken about the emperor in such a manner, even as the entire nation was deeply worried about his health. Then he came to the main point: It is a common error among Christians and people with Western inclinations, including so-called intellectuals, to fail to grasp that Western societies and Japanese society are based on fundamentally different religious concepts . . . Forgetting this premise, they attempt to place a Western structure on a Japanese foundation. I think this kind of mistake explains the demand for the emperor to bear full responsibility.
In Two Normal Towns:
The bust of the man caught my attention, but not because it was in any way unusual; such busts of prominent local figures can be seen everywhere in Japan. This one, however, was particularly grandiose. Smiling across the yard, with a look of deep satisfaction over his many achievements, was Hatazawa Kyoichi. His various functions and titles were inscribed below his bust. He had been an important provincial bureaucrat, a pillar of the sumo wrestling establishment, a member of various Olympic committees, and the recipient of some of the highest honors in Japan. The song engraved on the smooth stone was composed in praise of his rich life. There was just one small gap in Hatazawa s life story as related on his monument: the years from 1941 to 1945 were missing. Yet he had not been idle then, for he was the man in charge of labor at the Hanaoka mines.
In Clearing Up the Ruins:
But the question in American minds was understandable: could one trust a nation whose official spokesmen still refused to admit that their country had been responsible for starting a war? In these Japanese evasions there was something of the petulant child, stamping its foot, shouting that it had done nothing wrong, because everybody did it.
Japan seems at times not so much a nation of twelve-year-olds, to repeat General MacArthur s phrase, as a nation of people longing to be twelve-year-olds, or even younger, to be at that golden age when everything was secure and responsibility and conformity were not yet required.
For General MacArthur was right: in 1945, the Japanese people were political children. Until then, they had been forced into a position of complete submission to a state run by authoritarian bureaucrats and military men, and to a religious cult whose high priest was also formally chief of the armed forces and supreme monarch of the empire.
I saw Jew S ss that same year, at a screening for students of the film academy in Berlin. This showing, too, was followed by a discussion. The students, mostly from western Germany, but some from the east, were in their early twenties. They were dressed in the international uniform of jeans, anoraks, and work shirts. The professor was a man in his forties, a 68er named Karsten Witte. He began the discussion by saying that he wanted the students to concentrate on the aesthetics of the film more than the story. To describe the propaganda, he said, would simply be banal: We all know the what, so let s talk about the how. I thought of my fellow students at the film school in Tokyo more than fifteen years before. How many of them knew the what of the Japanese war in Asia.

Russell Coker: A Long Term Review of Android Devices

Xperia X10 My first Android device was The Sony Ericsson Xperia X10i [1]. One of the reasons I chose it was for the large 4 screen, nowadays the desirable phones (the ones that are marketed as premium products) are all bigger than that (the Galaxy S6 is 5.1 ) and even the slightly less expensive phones are bigger. At the moment Aldi is advertising an Android phone with a 4.5 screen for $129. But at the time there was nothing better in the price range that I was willing to pay. I devoted a lot of my first review to the default apps for SMS and Email. Shortly after that I realised that the default email app is never going to be adequate (I now use K9 mail) and the SMS app is barely adequate (but I mostly use instant messaging). I ve got used to the fact that most apps that ship with an Android device are worthless, the camera app and the app to make calls are the only built in apps I regularly use nowadays. In the bug list from my first review the major issue was lack of Wifi tethering which was fixed by an update to Android 2.3. Unfortunately Android 2.3 ran significantly more slowly which decreased the utility of the phone. The construction of the phone is very good. Over the last 2 years the 2 Xperia X10 phones I own have been on loan to various relatives, many of whom aren t really into technology and can t be expected to take good care of things. But they have not failed in any way. Apart from buying new batteries there has been no hardware failure in either phone. While 2 is a small sample size I haven t see any other Android device last nearly as long without problems. Unfortunately I have no reason to believe that Sony has continued to design devices as well. The Xperia X10 phones crash more often than most Android phones with spontaneous reboots being a daily occurrence. While that is worse than any other Android device I ve used it s not much worse. My second review of the Xperia X10 had a section about ways of reducing battery use [2]. Wow, I d forgotten how much that sucked! When I was last using the Xperia X10 the Life360 app that my wife and I use to track each other was taking 15% of the battery, on more recent phones the same app takes about 2%. The design of modern phones seems to be significantly more energy efficient for background tasks and the larger brighter displays use more energy instead. My father is using one of the Xperia phones now, when I give him a better phone to replace it I will have both as emergency Wifi access points. They aren t useful for much else nowadays. Samsung Galaxy S In my first review of the Galaxy S I criticised it for being thin, oddly shaped, and slippery [3]. After using it for a while I found the shape convenient as I could easily determine the bottom of the phone in my pocket and hold it the right way up before looking at it. This is a good feature for a phone that s small enough to rotate in my pocket the Samsung Galaxy Note series of phones is large enough to not rotate in a pocket. In retrospect I think that being slippery isn t a big deal as almost everyone buys a phone case anyway. But it would still be better for use on a desk if the bulge was at the top. I wrote about my Galaxy S failing [4]. Two of my relatives had problems with those phones too. Including a warranty replacement I ve seen 4 of those phones in use and only one worked reliably. The one that worked reliably is now being used by my mother, it s considerably faster than the Xperia X10 because it has more RAM and will probably remain in regular use until it breaks. CyanogenMod I tried using CyanogenMod [5]. The phone became defective 9 months later so even though CyanogenMod is great I don t think I got good value for the amount of time spent installing it. I haven t tried replacing the OS of an Android phone since then. I really wish that they would start manufacturing phones that can have the OS replaced as easily as a PC. Samsung Galaxy S3 and Wireless Charging The Galaxy S3 was the first phone I owned which competes with phones that are currently on sale [6]. A relative bought one at the same time as me and her phone is running well with no problems. But my S3 had some damage to it s USB port which means that the vast majority of USB cables don t charge it (only Samsung cables can be expected to work). After I bought the S3 I bought a Qi wireless phone charging device [7]. One of the reasons for buying that is so if a phone gets a broken USB port then I can still use it. It s ironic that the one phone that had a damaged USB port also failed to work correctly with the Qi card installed. The Qi charger is gathering dust. One significant benefit of the S3 (and most Samsung phones) is that it has a SD socket. I installed a 32G SD card in the S3 and now one of my relatives is happily using it as a media player. Nexus 4 I bought a Nexus 4 [8] for my wife as she needed a better phone but didn t feel like paying for a Galaxy S3. The Nexus 4 is a nice phone in many ways but the lack of storage is a serious problem. At the moment I m only keeping it to use with Google Cardboard, I will lend it to my parents soon. In retrospect I made a mistake buying the Nexus 4. If I had spent a little more money on another Galaxy S3 then I would have had a phone with a longer usage life as well as being able to swap accessories with my wife. The Nexus 4 seems reasonably solid, the back of the case (which is glass) broke on mine after a significant impact but the phone continues to work well. That s a tribute to the construction of the phone and also the Ringke Fusion case [9]. Generally the Nexus 4 is a good phone so I don t regret buying it. I just think that the Galaxy S3 was a better choice. Galaxy Note 2 I got a Samsung Galaxy Note 2 in mid 2013 [10]. In retrospect it was a mistake to buy the Galaxy S3, the Note series is better suited to my use. If I had known how good it is to have a larger phone I d have bought the original Galaxy Note when it was first released. Generally everything is good about the Note 2. While it only has 16G of storage (which isn t much by today s standards) it has an SD socket to allow expansion. It s currently being used by a relative as a small tablet. With a 32G SD card it can fit a lot of movies. Bluetooth Speakers I received Bluetooth speakers in late 2013 [11]. I was very impressed by them but ended up not using them for a while. After they gathered dust for about a year I started using them again recently. While nothing has changed regarding my review of the Hive speakers (which I still like a lot) it seems that my need for such things isn t as great as I thought. One thing that made me start using the Bluetooth speakers again is that my phone case blocks the sound from my latest phone and makes it worse than phone sound usually is. I bought Bluetooth speakers for some relatives as presents, the relatives seemed to appreciate them but I wonder how much they actually use them. Nexus 5 The Nexus 5 [12] is a nice phone. When I first reviewed it there were serious problems with overheating when playing Ingress. I haven t noticed such problems recently so I think that an update to Android might have made it more energy efficient. In that review I was very impressed by the FullHD screen and it made me want a Note 3, at the time I planned to get a Note 3 in the second half of 2014 (which I did). Galaxy Note 3 Almost a year ago I bought the Samsung Galaxy Note 3 [13]. I m quite happy with it at the moment but I don t have enough data for a long term review of it. The only thing to note so far is that in my first review I was unhappy with the USB 3 socket as that made it more difficult to connect a USB cable in the dark. I ve got used to the socket and I can now reliably plug it in at night with ease. I wrote about Rivers jeans being the only brand that can fit a Samsung Galaxy Note series phone in the pocket [14]. The pockets of my jeans have just started wearing out and I think that it s partly due to the fact that I bought a Armourdillo Hybrid case [15] for my Note 3. I ve had the jeans for over 3 years with no noticable wear apart from the pockets starting to wear out after 10 months of using the Armourdillo case. I don t think that the Armourdillo case is bad, but the fact that it has deep grooves and hard plastic causes it to rub more on material when I take the phone out of my pocket. As I check my phone very frequently this causes some serious wear. This isn t necessarily a problem given that a phone costs 20* more than a pair of jeans, if the case was actually needed to save the phone then it would be worth having some jeans wear out. But I don t think I need more protection than a gel case offers. Another problem is that the Armourdillo case is very difficult to remove. This isn t a problem if you don t need access to your phone, IE if you use a phone like the Nexus 5 that doesn t permit changing batteries or SD cards. But if you need to change batteries, SD cards, etc then it s really annoying. My wife seems quite happy with her Armoudillo case but I don t think it was a good choice for me. I m considering abandoning it and getting one of the cheap gel cases. The sound on the Note 3 is awful. I don t know how much of that is due to a limitation in the speaker and how much is due to the case. It s quite OK for phone calls but not much good for music. Tablets I m currently on my third tablet. One was too cheap and nasty so I returned it. Another was still cheap and I hardly ever used it. The third is a Galaxy Note 10 which works really well. I guess the lesson is to buy something worthwhile so you can use it. A tablet that s slower and has less storage than a phone probably isn t going to get used much. Phone Longevity I owned the Xperia X10 for 22 months before getting the Galaxy S3. As that included 9 months of using a Galaxy S I only had 13 months of use out of that phone before lending it to other people. The Galaxy S3 turned out to be a mistake as I replaced it in only 7 months. I had the Note 2 for 15 months before getting the Note 3. I have now had the Note 3 for 11 months and have no plans for a replacement any time soon this is the longest I ve owned an Android phone and been totally satisfied with it. Also I only need to use it for another 4 months to set a record for using an Android phone. The Xperia was free as part of a telco contract. The other phones were somewhere between $500 and $600 each when counting the accessories (case, battery, etc) that I bought with them. So in 4 years and 7 months I ve spent somewhere between $1500 and $1800 on phones plus the cost of the Xperia that was built in to the contract. The Xperia probably cost about the same so I ll assume that I spent $2000 on phones and accessories. This seems like a lot. However that averages out to about $1.20 per day (and hopefully a lot less if my Note 3 lasts another couple of years). I could justify $1.20 per day for either the amount of paid work I do on Android phones or the amount of recreational activities that I perform (the Galaxy S3 was largely purchased for Ingress). Conclusion I think that phone companies will be struggling to maintain sales of high end phones in the future. When I chose the Xperia X10 I knew I was making a compromise, the screen resolution was an obvious limitation on the use of the device (even though it was one of the best devices available). The storage in the Xperia was also a limitation. Now FullHD is the minimum resolution for any sort of high-end device and 32G of storage is small. I think that most people would struggle to observe any improvement over a Nexus 5 or Note 3 at this time. I think that this explains the massive advertising campaign for the Galaxy S6 that is going on at the moment. Samsung can t sell the S6 based on it being better than previous phones because there s not much that they can do to make it obviously better. So they try and sell it for the image.

Russell Coker: Phone Car Accessories

Tree Frog Dashboard Mat phone stuck to fridge I ve been given some more MobileZap products to review. The first is the Tree Frog anti-slip dashboard mat [1]. This is designed to allow a phone to stick to an angled surface of the inside of the car without slipping. The pictures on the web site show a phone stuck to a curved angular surface of a car dash. To test this I stuck my phone to my fridge, the flat metal surface of the fridge and the almost flat plastic surface of the gel case of my phone are pretty much ideal surfaces for the sticky mat to adhere to. But even so keeping my phone stuck to a vertical surface is impressive. This mat is cheap enough that it could be used for many other tasks than securing a phone in a car, for example it could be used to stick a phone to the wall of your office. It s apparently washable and can be expected to keep gripping things if washed regularly. One thing that could be improved in the mat would be to have some holes in it. When I detached my phone from the fridge some large air bubbles developed between the mat and the fridge, this would be a problem if I wanted to regularly stick my phone to a flat surface such as an office wall. When in my car it didn t work nearly as well. The pattern on the surface of the car dash which is designed to avoid glare when driving is difficult to stick to, it s a bit like trying to attach sticky-tape to unpainted wood for similar reasons. A phone will still remain in place on a 30 degree angle from the horizontal (which is significant) but the mat grips much more tightly to the phone than the dash, which is a little inconvenient as the mat stays attached to the phone when you remove it from the dash. Sorry for the boring picture, it s black and flat so there s not much scope for making it interesting. 3.1A USB Car Charger AA battery charger and 3.1A car charger Above is a picture of a 3.1A USB car charger and a AA battery charger. The car charger isn t particularly exciting, but providing 3.1A through two USB sockets is noteworthy it can charge one device at 2.1A (the maximum any device draws) or two devices for a total of up to 3.1A [2] (with protection against over-current). Previously in my car I used the 2.1A charger that shipped with my Galaxy Note 2 and an inverter to provide 240VAC as the devices I had to charge a phone from a car socket didn t provide enough current. This new device uses less space and also allows charging two phones at once. One problem with this device was finding USB cables that could handle the current, for benchmarking I used a phone that was running Ingress and acting as a Wifi access point. I discovered that the cables that Samsung ships with their recent devices (Galaxy Note 2 and Galaxy Note 10.1 tablet) seem to work best and support charging my Galaxy Note 2 or my wife s Nexus 5 while playing Ingress and running as a Wifi AP. Most of the other cables that I have in my collection won t even allow a phone to remain at the same charge level while playing Ingress. AA Emergency Phone Charger The AA phone charger is best suited for emergency use only, it takes one AA battery and has limited current capacity [3]. A NiMh rechargeable battery has a nominal Voltage of 1.2V, to provide 5V to charge a phone the Voltage has to be boosted by a factor of 4.16 which would reduce the current by a factor of 4.16 if the charger was 100% efficient. As 100% efficiency is impossible the current would be reduced even more. It seems unlikely that a AA battery would be able to sustain a current of 2A so the supply from that charger would be less than 500mA IE less than the least capable PC USB port or mains powered phone charger. A test with a Nexus 5 showed the phone charge level decreasing while being very lightly used (mostly just checking whether the charge level was increasing) when a NiMH battery was connected. A test with an alkaline battery and the same Nexus 5 showed the phone charge level increasing when lightly used but it probably wouldn t do so while playing Ingress. It seems that a single NiMH AA battery can only be used for charging a phone in a real emergency situation (IE an act of god type disaster not a need to level up in Ingress). If mains power was out then you could charge a phone while it s turned off (AFAIK all Android phones support this) and then use it once it s charged. This charger supports a wide range of phones (including LG phones from 5+ years ago and Nokia from ~10 years ago) so it could be good for charging an old phone in an emergency. Older phones need less power to charge and generally last longer between charges. With an alkaline battery the charger works a lot better, but it s still for emergency use as I generally only use rechargeable batteries. This is a device I might put in the bottom of my case when travelling, not a device that I ll use regularly. I don t think that this is a deficiency in the product, it s just a limit of what can be done with the power requirements of modern phones and the capabilities of AA batteries. If you want a battery to use while playing Ingress you definitely need something a lot larger. This charger is good for emergencies but not suitable for my main use (charging phones while playing Ingress) so I ll give it to my parents, they do a lot of hiking and camping and my father often goes fishing. Taking a few AA batteries to charge a phone would be much more convenient for such use than taking one of the larger batteries I use for Ingress. Also as the charger is relatively cheap there s less potential financial loss if you drop it in sea-water. 20800mAh Battery picture of 20800mAh USB battery Above is a picture of a 20800mAh battery pack that MobileZap sent me [4]. I haven t yet discovered what it s capacity is, during the recent Interitus anomaly it kept my Galaxy Note 2 and my wife s Nexus 5 adequately charged for 5 hours of intensive Ingress playing (we alternated between phones). Without an external battery it would be unusual for either of those phones to last for 2 hours. The battery has two ports labeled 1A and 2.1A which implies that it can supply a total of 3.1A. I am a little dubious of that implication. After the Interitus anomaly my wife and I had dinner with some friends and I let a friend charge her Samsung Galaxy S5 on the battery at the same time as my Note 2 (which claimed to be 2% charged). When I connected my friend s phone my phone instantly shut itself down due to lack of charge, so I presume that the supply on the 2.1A port is reduced when a demanding device is connected to the 1A port. The next day my wife and I went to the city again to play Ingress and attend a protest against some of the awful things that the Abbott government is doing. As an experiment I didn t charge this battery to see how it would go for two days of use charging two phones. Again there was no problem and it still claimed to be half charged when we got home. So far the only problem I ve found with this battery is that it never reports being fully charged, not even if I leave it on charge for days. That doesn t seem to be a great problem to me, if I disconnect it before it s fully charged then that won t hurt the battery life (unlike NiCd batteries that have to be fully charged every time) and even if it s not fully charged it will still charge phones for a long time. The battery is about 19cm long. I have jeans with unusually large pockets to fit large phones [5] so I can fit this battery in my pocket while a USB cable is connected to charge my phone. I also have a new winter jacket from Scottwear which has pockets that can fit the battery (and lots of other things). Anyone who doesn t have such clothing should plan to use a backpack, handbag, or some other bag this type of battery won t fit in the pockets in most clothing. MobileZap also has some other interesting Nexus 5 accessories [6].

Jon Dowland: 2012 In Review

2013 is nearly all finished up and so I thought I'd spend a little time writing up what was noteable in the last twelve months. When I did so I found an unfinished draft from the year before. It would be a shame for it to go to waste, so here it is. 2012 was an interesting year in many respects with personal highs and lows. Every year I see a lots of "round-up"-style blog posts on the web, titled things like "2012 in music", which attempt to summarize the highlights of the year in that particular context. Here's JWZ's effort, for example. Often they are prefixed with statements like "2012 was a strong year for music" or whatever. For me, 2012 was not a particularly great year. I discovered quite a lot of stuff that I love that was new to me, but not new in any other sense. In Music, there were a bunch of come-back albums that made the headlines. I picked up both of Orbital's Wonky and Brian Eno's Lux (debatably a comeback: his first ambient record since 1983, his first solo effort since 2005, but his fourth collaborative effort on Warp in the naughties). I've enjoyed them both, but I've already forgotten Wonky and I still haven't fully embraced Lux (and On Land has not been knocked from the top spot when I want to listen to ambience.) There was also Throbbing Gristle's (or X-TG) final effort, a semi/post-TG, partly posthumous double-album swan song effort which, even more than Lux, I still haven't fully digested. In all honesty I think it was eclipsed by the surprise one-off release of a live recording of a TG side project featuring Nik Void of Factory Floor: Carter Tutti Void's Transverse, which is excellent. Ostensibly a four-track release, there's a studio excerpt V4 studio (Slap 1) which is available from (at least) Amazon. There's also a much more obscure fifth "unreleased" track cruX which I managed to "buy" from one of the web shops for zero cost. The other big musical surprise for me last year was Beth Jeans Houghton and the Hooves of Destiny: Yours Truly, Cellophane Nose. I knew nothing of BJH, although it turns out I've heard some of her singles repeatedly on Radio 6, but her band's guitarist Ed Blazey and his partner lived in the flat below me briefly. In that time I managed to get to the pub with him just once, but he kindly gave me a copy of their album on 12" afterwards. It reminds me a bit of Goldfrapp circa "Seventh Tree": I really like it and I'm looking forward to whatever they do next. Reznor's How To Destroy Angels squeezed out An Omen EP which failed to set my world on fire as a coherent collection, despite a few strong songs individually. In movies, sadly once again I'd say most of the things I recall seeing would be "also rans". Prometheus was a disappointment, although I will probably rewatch it in 2D at least once. The final Batman was fun although not groundbreaking to me and it didn't surpass Ledger's efforts in The Dark Knight. Inception remains my favourite Nolan by a long shot. Looper is perhaps the stand-out, not least because it came from nowhere and I managed to avoid any hype. In games, I moaned about having moaning about too many games, most of which are much older than 2012. I started Borderlands 2 after enjoying Borderlands (disqualified on age grounds) but to this day haven't persued it much further. I mostly played the two similar meta-games: The Playstation Plus download free games in a fixed time period and the more sporadic but bountiful humble bundle whack-a-mole. More on these another time. In reading, as is typical I mostly read stuff that was not written in 2012. Of that which was, Charles Stross's The Apocalypse Codex was an improvement over The Fuller Memorandum which I did not enjoy much, but in general I'm finding I much prefer Stross's older work to his newer; David Byrne's How Music Works was my first (and currently last) Google Books ebook purchase, and I read it entirely on a Nexus 7. I thoroughly enjoyed the book but the experience has not made a convert of me away from paper. He leans heavily on his own experiences which is inevitable but fortunately they are wide and numerous. Iain Banks' Stonemouth was an enjoyable romp around a fictional Scottish town (one which, I am reliably informed, is incredibly realistical rendered). One of his "mainstream" novels, It avoided a particular plot pattern that I've grown to dread with Banks, much to my suprise (and pleasure). Finally, the stand-out pleasant surprise novel of the year was Pratchett and Baxter's The Long Earth. With a plot device not unlike Banks' Transition or Stross's Family Trade series, the pair managed to write a journey-book capturing the sense-of-wonder that these multiverse plots are good for. (Or perhaps I have a weakness for them). It's hard to find the lines between Baxter and Pratchett's writing, but the debatably-reincarnated Tibetan Monk-cum-Artificial Intelligence 'Lobsang' must surely be Pratchett's. Pratchett managed to squeeze out another non-Discworld novel (Dodger) as well as a long-overdue short story collection, although I haven't read either of them yet. On to 2013's write-up...

Russell Coker: Clothing and Phone Cameras

In 2012 I wrote about my jeans from Rivers that fit the largest available phones (and the smaller tablets) in their pockets [1]. Those jeans are still working well for me, I can add the fact that they don t wear out quickly to the list of positive attributes. Recently my sister asked for advice on getting a new phone, she was considering the Samsung Galaxy Note 2 (the phone I m using now) because it apparently takes better pictures than the Nexus 4 she s using. I ve used both those phones and I hadn t noticed a difference in picture quality, but there is some variation in manufacturing and it could be that I ve got a below average Note 2 and a better than average Nexus 4 so I ll assume for the sake of discussion that my sister would actually get an improvement in picture quality by using a Note 2. If you have a phone that doesn t have the picture quality you desire then one option is to buy a phone with a better camera, but you will be limited by issues of physics. A thin phone has a short focal length which means that the lens has to be small and therefore the amount of light that gets to the sensor is small. The Nokia Lumia 1020 has some of the best camera hardware that you ll find in a phone, but it s still only 14.5mm thick where the camera is and that will limit the quality a lot. Any compact camera should be able to beat all phone cameras in terms of picture quality in most areas. The Samsung Galaxy Camera [2] is also worth considering, it has more features than a typical compact camera and good GUI that allows novice photographers to take advantage of it. Also being able to blog your photos directly from the camera could be a useful feature. But the big down-side of a compact camera is that it s not that compact. Most people won t find it convenient to carry a compact camera with them at all times and therefore they might miss a good opportunity to take a photo. The Galaxy Note series of phones also suffer in this regard because they are larger than most phones. If your phone won t fit in your pocket and you have it in your backpack when on the move or on a bench at home then you will probably miss some good photos. As I was at a Rivers store recently I tested my Note 2 in the pockets of women s jeans. Rivers scored very poorly in this regard, one pair of women s jeans had fake pockets (this is just wrong for working clothes) and of the rest only one pair could fit a Note 2. The pair that fit a Note 2 didn t completely enclose the phone, one corner was sticking out, this would probably give a risk of having the phone fall out of the pocket and cause some discomfort to the wearer. I have a pair of shorts with similar size pockets and find it very annoying with the Note 2 in the pocket (for about 10 months of the year I wear jeans so this isn t a big deal). Rivers jeans only count as geeky jeans for male geeks. It s disappointing that with about a dozen different styles of women s jeans there didn t seem to be a single one with pockets of comparable size to the men s jeans. I had to recommend that my sister not get a phone from the Galaxy Note series if taking pictures is a priority due to the apparent difficulty in getting it to fit in a pocket and the probability that she would miss good photos due to this. In past discussions of phone size there have been mentions of the possibility of getting clothing altered. Does anyone have a good experience in getting clothes altered to have bigger pockets or in the case of women s clothing to have fake pockets replaced with real ones?

Next.
