Tomorrow, all being well, I should receive a new desktop computer. I ordered it upon Boxing Day so the turnaround is pretty good. Right now I have two desktop machines:

yours.my.flat

This machine is occaisionally used by my partner, but primarily exists to remotely backup my various servers. It runs rsnapshot to do a full rsync of four machines every six hours.

vain.my.flat

This is my day-to-day desktop machine. It is going to be replaced, and this will be rotated into the backup machine. The machine yours will sit in a closet for a couple of months then be donated to somebody local.

As with all the machines I've bought recently the new one is coming from Novatech - (Another company whos website has a suprising hostname.) The interesting parts of the spec are :

• AMD X2 4200 processor
• 2 x 500Gb SATA drives
• 4Gb memory

The biggest difference to me will be the significantly increased disk space which means that I'll be able to remove the external 120Gb USB hard drive I currently house my MP3 collection upon. By retiring vain and moving my current desktop machine to be the "random guest machine" and backup host I'll also have a lot more space for storing backups upon. (Full database backups every six hours; I'm paranoid...) Having 4Gb of memory will also mean that I can run more than 2 or 3 Xen guests at the same time. My plan is to setup at least the following guests:

• sarge.security-build.xen
• etch32.security-build.xen
• etch64.security-build.xen
• etch32.desktop.xen
• etch64.desktop.xen

The desktop machines will run GDM / X11 and will be available for logins via xdmcp - so that I can have a fully seperate working environment which is pristine and easily regenerated. Giving 5 xen instances 256Mb of memory each will leave me with close to 3Gb of disk for the host and that is three times what I hav enow! All in all I'm looking forward to the new machine enormously a bargain at ~ £290.

Some small portable MP3 players also allow reproducing images and videos (does anyone know why they call them MP4 players?), but they need the latter to be in some funny format called SMV (for devices with SigmaTel chipset. Other devices use different formats, such as AMV for devices with Actions chipset, MVS for those with Sunplus chipsets, MTV, DMV or ASF). SMV seems to stand for “SigmaTel Motion Video”, and was developed by SigmaTel Inc to allow users to transform common PC video files and watch them on their portable multimedia players (PMP). I’ve been trying to find out how to convert videos to this format for a while, to be able to watch them in a small gadget I bought some time ago, but haven’t been able to do so from Linux yet. All the converters seem to be privative, and just for Windows, although they seem to work with wine according to some reports I’ve read on the net. I’m not putting any closed-source software in my lappy anyway, so that’s not an option for me. I recently found a web page of someone developing a conversion tool for SMV called smvconv, based on mplayer and ffmpeg and released under a MIT/X11 license. It’s just a small C program and a shell script, and seems to be in a very preliminary stage, but the most important part is that he has also published the structure of SMV files, which seem to be, in fact, quite a simple format composed of some headers, a WAV audio file and some JPEG frames: An SMV file has three sections, concatenated together:

1. An IMA ADPCM .wav file, with header.
2. An SMV header.
3. A number of .jpeg files, with headers, each prepended by a 24-bit (3-byte) little-endian value representing the size, and buffered at the end with nulls, so that they are at predictable locations (the jpeg modulo). SMV is a constant-bit-rate format, but the underlying format (jpeg) is not. Proprietary encoders -according to smvconv’s author- probably make up for this by encoding at various qualities until a jpeg of the proper size is made.

The SMV header is a magic string in ASCII (”SMV002000″) followed by a number of 24-bit (3-byte) little-endian values representing the width, height, header length (in 3-byte words, starting with some magic “002″), some apparently constant value (1), the jpeg modulo, fps, number of frames. some apparently constant values (a 1 and a 0), the number of frames per jpeg, and 4 padding values (65793 == 0×010101). The default qualities seem to be 35kBps (”High”), 25kBps (”Medium”) and 16kBps (”Low”). Lets hope to have some working converter soon, so we can use this feature in those cheap players. I don’t remember where I put the USB connector for mine, but as soon as I find it -it seems to be non-standard, so no way to replace it with a new one, AFAIK- I’ll start experimenting with it.

I have now gotten into baking bread at home and I like the result greatly. The inspiration came from an anime Yakitate!! Japan! - a very funny anime about bread bakers with lots of parody on other anime and lots of over-the-top reactions to bread. It also has a lot of tips on baking your own bread which helps people get started. I have heard that ‘Yakitate!! Japan’ caused a bread baking mania in Japan on par with the Go mania from ‘Hikaru No Go’ (Off-side note: I wonder if making an anime about developing free software would turn people in Japan and all over the world to do it more?) I watched the anime a couple years back and promptly forgot about it, but now when I was thinking about what anime to show to my girlfriend it came back to me. After that we both decided that we need an oven to bake bread in, unfortunately the flat we are in has no oven, so we had to buy a free-standing one. After much research and deliberation and some good advice from my friends, I got us a Samsung CE1071AR microwave oven with grill and a convection oven function. It has been the best decision - cooking with this thing is easy and painless. It is large enough for one large loaf of bread or a bunch of cookies in two levels. It has a steam-based self-clean function and an automatic preheat function. It can do all the things that a microwave oven can do and also combine regular oven with microwaves. And best of all it also has a 40 degree setting in the convectional oven mode - that is perfect for raising bread right in the oven. I am starting with the simplest bread recipes from The Fresh Loaf site tutorial section and in short order was able to produce some of the best tasting bread I ever had. You can see the result above. Now when my girlfriend and her sister decided to cook all kinds of stuff for Christmas I was not bored, but rather the opposite happened - I participated and had fun. Even more so - we are now watching the ‘Yakitate!! Japan’ anime, together with my girlfriend, looking for new tips for the cooking. I just might try to make a croissant next

Most audio players offer visualizations. Unfortunately most of them either are just plain boring or don't really visualize the music very well. KDE's amarok has one that is really excellent: jakdaw. Jakdaw does a good job of both following and representing the intensity of the music. And it generates an amazing display of colors. But even with a good visualization a lot of music is not all that interesting to watch. Over the last month or so I've occasionally been "looking" through my music collection. The visualizations are surprisingly varied for different artists. And though a lot of them are nice to watch, some artists consistently produce much more varied and artistic displays than others. To some degree it is predictable, but not always. Quite often the visualization is a lot less interesting than you'd expect and especially some slower or quieter songs produce much more interesting displays than you'd expect. A blanket of sound does not produce a very interesting display, but strong accents and mood changes do. As is often the case in art, the real challenge in composing music seems to be leaving things out and to have individual instruments play their own tune instead of having everything move together. The two artists that really stand out so far are Björk and Faithless. Both consistently produce visualizations that are at times stunningly beautiful and also show a lot more detail in the music than others. For Björk It's Oh So Quiet (from Post) and Violently Happy (from Debut) are very nice, but two songs that really stand out are Hunter (from Homogenic) and Hyper Balad (from Post). For Faithless songs like We Come 1 and Tarantula (from Outrospective), and Salva Mea and Insomnia (from Reverence) are truly worth watching.

One great thing about kids — especially kids who have not been overexposed to TV media — is how easily entertained they are. We recently showed Esther some Looney Tunes cartoons from the 1940’s (on a real TV, no less!) and she couldn’t stop laughing. It is refreshing to see someone spellbound by animated content that didn’t require a rendering farm to create. I’m sure she’ll be jaded soon enough, but we’re trying to drag it out as long as possible by providing only very occasional small doses. This piece on the end of reading as a cultural activity is chock full of interesting statistics. This excerpt, in particular, is relevant here:

In August, scientists at the University of Washington revealed that babies aged between eight and sixteen months know on average six to eight fewer words for every hour of baby DVDs and videos they watch daily. A 2005 study in Northern California found that a television in the bedroom lowered the standardized-test scores of third graders. And the conflict continues throughout a child s development. In 2001, after analyzing data on more than a million students around the world, the researcher Micha Razel found little room for doubt that television worsened performance in reading, science, and math. The relationship wasn t a straight line but an inverted check mark : a small amount of television seemed to benefit children; more hurt. For nine-year-olds, the optimum was two hours a day; for seventeen-year-olds, half an hour. Razel guessed that the younger children were watching educational shows, and, indeed, researchers have shown that a five-year-old boy who watches Sesame Street is likely to have higher grades even in high school. Razel noted, however, that fifty-five per cent of students were exceeding their optimal viewing time by three hours a day, thereby lowering their academic achievement by roughly one grade level.

It certainly doesn’t surprise me that television–even educational TV–is generally not good for kids. The “inverted check mark” bit was a surprise, though. Who would guess that two hours a day is optimal for the nine-year-old brain? On a related note, Kiddie Records Weekly (recommended by about.com here) is an astonishingly extensive source of free children’s books in MP3 format. It’s also an excellent example of the increasing relevance of bittorent in enabling wide economical distribution of legitimate content. The content is primarily (exclusively?) digitized vinyl records from the 1930’s and 1940’s. Fortunately, Alice in Wonderland gets no worse with age. To complete the nostalgia circuit, who can forget “loaf of bread, a container of milk, and a stick of butter” (via sketchelement, quite a while ago): These are good times to be a kid. Or maybe just to be a parent. Technorati Tags: Looney Tunes, Alice in Wonderland, Reading, TV, Cartoons, Sesame Street, Bittorrent

Some days ago I wrote down my experiences with packaging docbook-defguide. The main (remaining) issues I mentioned were the resources and the time the package needs to build. Even on an AMD X2 4600+ with 6GB of RAM it needs 7-8 hours. Today I met with Torsten Werner. He mentioned, that there are some move JVMs I could try. So I tested alternatives to GIJ this night. I found this short summary about free JVMs, which was some kind of interesting. I began with cacao, which seemed to be fast, but it was killed very early in the build process with an java.lang.OutOfMemory error. Even playing around with the -Xms and -Xmx switches in buildtools/saxon.sh did not help. So I dropped cacao from the list. Seems both cacao and kaffe create similar problems here and are not suitable for building the package. Second alternative I tried was sablevm. It directly throw out some warnings or errors so I directly dropped it too. Next JVM was jamvm. But it was as slow as GIJ. So I dropped it from the list of alternatives too. Then I found an interesting statement in the article I linked somewhere above. The author said, that his perfomance test time with GCJ/GIJ reduced from 433 to 9 seconds, when he compiled his application into a native executable. So I took a fast look through the docbook-defguide build dependencies and found, that Debian already provides a natively compiled Xerces package libxerces2-java-gcj. But there were no packages for libsaxon-java, libxml-commons-resolver1.1-java and docbook-xsl-saxon. So short and dirty: I downloaded the source for these packages, added the necessary stuff to get natively compiled packages too, built and installed them. Fortunately packages with native code already exist (JAXP 1.3 and Xerces) for their dependencies. And what should I say: Now building the TDG needs less then 512MB RAM and it builds in around an hour … even on my system. I will ask the Debian Java maintainers to add -gcj packages for Saxon and XML-Commons and fix my own docbook-xsl-saxon package. This will hopefully help maintaining docbook-defguide.

Just to confirm, yes, I do know of rss2email - it has the unfortunate side effect of needing an MTA configured to process the rss feeds and seperate them in to seperate maildirs, basically I wanted something that would write straight to the maildir for me because then I don't have to think about the config for the MTA on each machine that I want to use it on. Thanks to Martin for the suggestion of pandoc, I'll take a look at that over the next few days to see if it'll make the "plain text" generation slightly neater than the current HTMLParser based code.

I wanted to make 1.16.0 last release this year, but unfortunately one bug preventing reading of all SMS messages from some AT phones sneaked in, so I decided to make another quick release. Changelog is really short:

• Fixed reading of messages from AT phones using CMGL.

Other change is that I started to produce additional binary build for Windows - it does not use any external libraries (so no MySQL, PostgreSQL or Gettext support) and links statically. So you can just copy single binary and it should work anywhere. You can download from usual place: http://cihar.com/gammu/

Yesterday in the evening I uploaded MySQL 5.0.51-1 to Debian unstable. Unfortunately it took a bit longer to prepare the updated package than expected, mainly because 5.0.51 wasn't MySQL's best relase, and I had to backport and include some fixes from 5.0.52 and 5.0.54 to get it working (see the changelog for details). Then I had to wait a few more days until 5.0.45-5 got into testing before I could finally upload 5.0.51-1 to unstable.

The most important changes are:

• Testsuite is now enabled during build process, which requires some time, but it ensures that everything is fine with the build. I already found two gcc 4.2.x related bugs in 5.0.51 which were fixed before 5.0.51-1 was uploaded to Debian.
• Manpages re-added, MySQL AB has put them under the GPL so we could include them again after we had to remove them a few months ago.

Regarding the Community vs. Enterprise decision I had a discussion with Kaj Arn , Lenz Grimmer, Daniel Fischer and Monty Taylor on IRC last week and we decided to stay with the Community Edition in Debian for now, and see what the future will bring us.

Working on the project here at Japan is sometimes really fun. Tomorrow we have important delivery and this afternoon out Japanese colleagues decided that 2000 pages describing our software solution is not enough. They need at least 500 extra pages. Fortunately it could be any existing documentation, so we randomly choose POSIX standard Part 1 (535 pages) and the Eclipse basic tutorial (592 pages). Japanese guys were really happy that they have 1100 more pages and we're happy that we don't have to produce more documents. Now I only wonder why the hell customer is interested in quantity of paper and not in quality of work.

I was considering importing my car to Switzerland. When I moved in 2002, I asked the customs office about the process and was told that I'd need to pay taxes and fees, so I postponed the import until Day Unknown. Today, a very friendly customs official told me that this is not true and that I could have imported my car duty-free if I had done so as part of my move. Slightly annoyed, I went on to discover what those duties would be today. I found out that there are seven different types of fees I'll have to pay, and tried to understand the reason for these fees:

1. To import a car, you need a form 11.010, downloadable from the Swiss Customs Office. Because each download causes extra work for the administrator, they charge a nominal fee of CHF 0.70 to get the PDF file.

2. I take that form to the customs office. There, the officials will assemble around the car and attempt to lift it. I don't know why they do that, but they charge you between CHF 12 and CHF 15 per 100kg of weight. I think it must be recompensation for the hard physical labour. Also, each customs official can lift 100kg, which explains those figures they seemed a bit arbitrary at first.

3. Next, they'll ask 4% of the estimated value of the car as a car tax. They do this because the value of a car is directly related to the area it covers, and since Switzerland is so small, you effectively have to buy a couple of square metres for the car. It's not quite as easy as that though: once I bought the area under my car, I have to move the car away, because I cannot park my car on the area I just bought. I have to buy parking space for that. If I don't want to buy a parking space, I have to keep the car moving. In order to keep the car moving I need to fork over CHF 40 per year for a permit to drive the car on Swiss highways.

4. Now, I pay 7.6% value-added tax. It makes no difference that the car isn't new, that I am not selling or buying it, nor that I have already paid 16% VAT in Germany when I bought it. Since I am about to "consume" the car in Switzerland, I have to pay consumer tax. Since I also consume the physical labour the officials put into the car lifting exercise, as well as the area under the car I bought, I pay VAT for (car value + lifting tax + area under car). Unfortunately, the European Union will not pay back the consumer tax I previously paid as part of the export, since I already consumed the car there.

5. I then get a report about the import. This costs CHF 20. I don't need this report, but I have to buy it. The reason is that the computer admins are so overworked serving PDF files to future importers that they have not had time to stop the computers from printing this report, and the special paper and toner used by all administrative offices in Switzerland costs about CHF 20 per page. An alternative explanation is that CHF 20 is the smallest bit of "money" in Switzerland, everything else is "change".

6. I will also have to pay annual taxes for possession of a car, the value to be determined by the custom officials. Since I already paid for the area under the car while moving and while stationary, I think the annual car tax is levied for environmental reasons. A lot of people drive through Switzerland to get from Germany to Italy or from Austria to France, pumping a lot of exhaust gas into the Swiss air. This makes them guilty, just like inhabitants of Switzerland who own a car are guilty. Due to legal reasons, the Swiss government can only punish Swiss people for those sins, so the annual car tax is a little higher to cover for all environmental damage. It is doubtful where the money goes, though. I also have to continue paying taxes in Germany, because I still have a residence with my parents.

7. Finally, I have to purchase a car insurance. That insurance does not insure the car, it insures the others on the road. Actually, it is a driver-car-dependent insurance, meaning that the others are insured only if I am the driver of my car. If I drive another car, or someone else drives my car, the others will not be insured. unless I pay higher insurance fees. Because cars with a larger area under them and those that require more people to lift them are more dangerous, the insurance fee is proportional to the car density. At least I can give up my German insurance and be covered by the Swiss insurance. However, I cannot keep my German insurance and be covered in Switzerland. I think this is because the head of customs department and the CEO of the insurance company have sex with each other.

It's been a great day, given how much I learnt. I finally understand why people have fought wars over taxes. I think I may leave the car in Germany. PS: Yes, this post may be considered hyperbole. NP: The Pineapple Thief: 8 Days Later

Christmas is billed as a family occasion and a huge amount of advertising money is spent convincing people that they need to have big expensive family events. This is good for the advertisers but not good for people who have no family to meet up with (orphans, people who live in different countries to their families, and people who don’t get along with their relatives). If any of your friends don’t have an event planned for Christmas day then it’s a good idea to invite them to your family party if possible. When I was younger there were two occasions when friends who didn’t have a possibility of attending a party with their own family attended a Christmas party with my family. Unfortunately I’m not in a position to make such an offer this year, but I encourage everyone who knows of someone with no plans to consider the possibility of inviting them to a party. Another possibility is that Linux people who have no option of a family party could arrange a Linux community Christmas party.

It's been an interesting week. For those of you that haven't been following along: we lost power Tuesday and have been without ever since.

Yesterday was the annual Christmas party at work. About an hour away, supposed to be there at 6. So at 2:30 I went outside to see if I could get the car out past all the snow. At first, YES! But then, halfway down the driveway... well, no. Our driveway needs help. It's actually lower than the fields around it. Thankfully it's on a hill so it doesn't flood, but it does drift shut when there's snow. So the car got stuck. I dug it out, and it got stuck again. And a third time.

I eventually called my dad to see if he'd be willing to come over with his tractor and open up our driveway. He said yes, and drove the 5 miles in his tractor -- which has no cab, and it was below freezing -- and got the driveway open, and helped me get the car unstuck. We had planned to leave at 4, to give us time to get Jacob to the babysitter. We didn't think a babysitter would enjoy spending the evening at a cold house with only a generator providing power, so we were taking him to their place. Well, we left about 4:30.

We got down our driveway, onto the road, and hey -- more drifts. Yay. Got out onto the highway, over to the road to their place. Which someone, ahem, had assured me was a paved road. But instead we got 5 miles on a very drifty east-west country road. That's the deepest snow I've ever put a car through, and I am still surprised that we didn't get stuck anywhere.

So then we dropped off Jacob, and off to the party, and squeaked in just a few minutes late. Phew. It was nice to be out of the house, too.

When we picked up Jacob later -- taking the non-drifty route -- he was sleeping, of course. I carried him out to the car and put him in his seat. There's nothing quite like carrying a sleeping boy snuggled into you to make you forget the lack of electricity outside.

Today we went to church. Church was canceled last Sunday, and the Wednesday evening activities were too. So I think everybody made an effort to be there today. All sorts of electricity stories were heard. Generators moved around the countryside as those that owned them got power and loaned them out to those that didn't have power. The president of a nearby college called the church and offered two rooms at his personal residence to anyone that needed them. One woman announced during sharing time that her husband was taken to the hospital on Friday. They determined that he needed heart surgery, and that will happen tomorrow... and she added that she'd be with him for a couple of days, so if anyone needed a warm house for a family, theirs was available and had a couple of bedrooms, fridge, and garage that people were welcome to use.

At noon there was a free lunch offered to anyone still without power. We went and enjoyed some warm soup and bread with about 30 others.

After that, we went to my parents' place to do some laundry, then came home.

We ate supper. As Terah got up to give Jacob some more chili, I suggested that she look out the window and see if any yard lights were on yet. I had flipped our master breaker off, just to be extra cautious due to having wired our furnace into the generator temporarily. So this is how we would tell that power was back on somewhere (though we did check it periodically during the day). Terah looked out the window, and said, "I DO see yard lights out there... Do you think?" I got up, went downstairs, flipped the breaker, and light came on! We turned on the lights -- Jacob had missed them -- and plugged in the Christmas tree. The power had come on for people miles in either direction from us at the same time. Dad came over to get our electrical box back to normal state and to help me load up the generator to return tomorrow.

There's nothing quite like this to make us feel fortunate to be a part of such a caring community of friends and family -- people who don't think twice about helping out someone in need, even in the midst of having a husband hospitalized.

Jacob didn't seem to mind the power outage. Except for one thing. He is very excited about lights these days. I can spend 15 to 30 minutes exploring lights with him, especially in the kitchen. He will point at a light and say "da?" ("that"). "Da? Da?" means he wants it turned on or off. We'll go to the light switch, and he'll get to flip it, or watch while I do. "Dooooo!" is his excited response.

Well, when he wants something and it's not happening fast enough for him, "Da? Da?" changes to "Da!... Da!..." and then to "DA!! DA!!" and finally some fussing. That happened several times as we couldn't turn on lights.

Then we got to church this morning and boy was he excited. Lights everywhere! He'd point to one bright light and say "Da!" -- look at the light over there, dad! Point to another place and "Da!" Another one over here! And ceiling fans! Lights everywhere! He was so excited he was trying to jump up and down.

Jacob's favorite new word is "hi." He has just barely figured out how to say it, and it takes effort, and comes out very breathy -- but it's there. He can spend several minutes saying hi to someone over and over if he's in the right mood. He wouldn't say hi to the greeters at church, or anyone that said hi to him. But we were sitting in the back row, and halfway through the sermon, he started saying hi to the ushers that were behind us. I couldn't see them very well, but I imagine they were trying to keep from cracking up.

Sometimes it is extremely tempting to wave a huge, heavy, spiked cluebat around. Today I've decided to give in to this temptation. The case in point is the upload today by their maintainer of first cwidget and later aptitude. The fact that the maintainer blogged about both uploads probably means that he's pretty happy about it. Unfortunately I, and people in the Debian release team, were less than amused. Reason is that the uploads set back a complex transition of apt and related packages by at least a week. This is a transition we'd already been following and trying to get into testing for over a month and which was finally as good as ready to go. So what was so wrong about these uploads and what could (should?) the maintainer have done? First of all he should have realized that aptitude has become a rather central package in Debian with strong ties to apt and thus to a lot of other packages. Second, he should have checked whether his previous uploads had already migrated to testing and, if not, why not. The excellent testing migration page for aptitude (which is linked from its PTS page clearly shows that it is tied in a transition involving about a 100 packages in total. The right thing to do in such a case is to contact the release team (preferably at the debian-release mailing list, or at #debian-release). This would undoubtedly have resulted in a request to delay the uploads a few days until the transition had finished. Unfortunately that did not happen and cwidget was uploaded. Because of an ABI bump it ended up in NEW. Because of the transition I did a quick request to Joerg Jaspert to please delay accepting cwidget until the transition was over. But then a third mistake, and arguably the most serious one of the lot, was made. aptitude was uploaded for i386, built against the cwidget library which had not yet been accepted into unstable. Basically that means that an uninstallable package was uploaded. And of course it meant that at that point all efforts to finalize the transition for apt went down the drain. Some alternatives were discussed on how to deal with the new situation, including a sourcefull upload of the previous version of aptitude, but in the end it was decided to just accept the delay as one of the more annoying facts of life and instead ask Joerg to accept cwidget from NEW. In the end the damage may be a bit less than a week if the buildds cooperate (which they probably won't with cwidget still stuck at the wrong priority) and the RMs decide to force things. I sincerely hope that this story will make all Debian Developers and Debian Maintainers a bit more aware of the broader context and consequences of uploads. Oh, as I'm not an RM myself you may wonder what my interest is in this. We've got this great new feature in Debian Installer that adds support for multiple CDs during an installation (a feature that was lost with the integration of base-installer into D-I). However, we can only upload the relevant D-I component after apt 0.7.9 has reached testing...

When you live in NYC and have a demanding job, you tend to ignore the city (at least I do), that is until guests descend upon your place. And since a Large Family Clan has recently landed in my apt, I have spent the last few days trekking north, south, east, and west, across bridges, in parks, and memorials, eating, drinking, and passing out at night after the constant flurry of activity. Yesterday we headed pretty much as far north as you can go to pay a visit to the lovely Cloisters sitting high on a cliff. The Cloisters provides stellar views of the Hudson at the same time as it transports you back in time when a lot of energy was put into scribbling religious material on paper in really stunning and ornate ways. I have not paid a visit to the Cloisters since my undergraduate days and after yesterday’s stroll, I am sorry I waited until the frigid winter to do so. It is an *incredibly* serene place, especially the inner courtyard gardens, and if you need serenity (and I think anyone who lives in NYC, needs to counter the low-grade and high-grade exposure to constant noise with some noiseless environments), this is the place to go. We then made our way to the Columbia area to check out the campus, St. John the Divine (currently under renovation), and so I could pick up a book being held for me at the Book Culture bookstore (which I wish was a lot closer to me than it is)… It was nice to escape the blustering winter conditions and browse the rows of books in a warm and well lit environment. But after purchasing Information Please: Culture and Politics in the Digital Age, parts of which I am hoping to teach next semester, and flipping through the book, my new found serenity was replaced by some serious offense when the only index I could find was an author index. There was no subject index in sight, which at the time left me totally surprised!! Anyone who is in the business of using books as research tools knows the index is —-> indispensable. And a well indexed book is much appreciated (never mind what a non-existent index does). In fact, I felt like I stumbled on some rare object because I don’t think I have ever seen an academic book published in the last 30 years not sporting this useful tool and I wonder if 1) I have a bunk copy 2) The editors/authors forgot to include it and just pushed out the book anyway 3) This was a willful choice made for reasons hidden to the reader. I think I may have to contact Duke University Press and let me know they momentarily robbed me of my serenity

Its been a couple of weeks since the Open Source Developers’ Conference in Brisbane, but it was only now that I’ve got the time to blog about it. This is due to some work that got piled in my backlog (I haven’t been lazy enough to have this work all automated yet :(). First off, my trip to Brisbane was a long one, due to the UNDP travel agency giving me a route taking me to Bangkok first, because of my exchange grant’s papers made in short notice. No matter: this being my first ever international trip, this meant that I would be visiting two different countries in just one shot. Bangkok was just an overnight stay though, so I didn’t see much, but their new airport was nevertheless impressive. Arriving there at almost midnight, the only bright places I saw were the big Suvarnabhumi airport and the Novotel where I had my layover. After some sleep, I had a pleasant morning, but only a short one at Bangkok, as my flight to Brisbane followed after: The Brisbane flight was long, and I arrived just an hour before midnight. Now, my next problem was getting a place to stay. I took an airport shuttle to the Royal on the Park, where the conference will be held, first to see if there are any free rooms, or barring that, some recommendation on nearby places to stay, even if only for the night. I was quite anxious because I wasn’t able to arrange for accommodation prior to this trip (short notice, remember?), so I decided to go directly to the venue to be the best way of trying my luck. And try my luck it was! First, I was greeted by a front desk manager who turned out to be a fellow Filipino, and he helped me get a room in the hotel. At the time though, he could not guarantee that I can stay there for the duration of the trip (only for the night) but he would help me to find alternate accommodation instead on the next day. I thought that was good enough, since it was already midnight by the time I reached the hotel, and just a bed to sleep on for the night would do great for me to worry about moving elsewhere later. And the next day: Day 1 of OSDC: I was up rather too early that day; the worrying about moving elsewhere settled in too early as well, and had made me check out very early so I can hopefully look for that alternate accommodation by lunchtime. One by one, the attendees came, and soon enough more than a couple of hundred people were filling the main conference room, waiting for OSDC to begin. And we began with a keynote from Rusty Russell on C, the humbling language and Ian Clatworthy’s talk on distributed version control systems. After the keynote, I was notified by the hotel management that instead of moving elsewhere, I can just remain there for the duration of the conference. I was quite relieved! For the remainder of the day, I listened in on the Perl stream of talks from Kirrily Robert, Josh Heumann, and Jacinta Richardson, on packaging Perl modules, Perl 6, and Perl code optimizations, respectively. Kirrily’s talk was timely since I am writing a couple of Perl modules to be released on the CPAN (one, Tie::Amazon::S3, is now up On the morning Day 2, I listened in on Mark Rees’ talk on testing web applications using twill and a scripting language, like Python. I then followed Adam Kennedy’s talk on the CPAN 1.5, learning about CPAN::Mini, the CPANPLUS (which IIRC will be standard in Perl 5.10) and the Tiny modules in the process. More on the Perl stream continued with another talk from Josh Heumann on intermediate Perl testing, providing a humorous yet informative strategies not really just for testing Perl scripts or modules but for software testing in general: Later in the afternoon was Paul King’s talk on agile developer practices for dynamic languages, covering Groovy and Ruby. That was later followed by Leslie Hawthorn’s talk about the Google Summer of Code and the announcement of the Highly Open Participation contest for the young geeks who are not yet in college or university but would like to work on open source projects just like the SoC-ers. After the day’s schedule of talks, there was a break before the conference dinner, allowing also for a short keysigning session and CACert identity check. Then, we had the conference dinner, sponsored by Google. There was also a game held: every table makes up a team who, given some Play-dohs and imagination, are to make up a bug’; the best bug’ wins a free book. Unfortunately, my table/team didn’t win any books, but that was beside the point anyway, as the bugs that were made up were quite something: On the last day, the morning talks I attended were all about Ruby and Rails. Nic Williams gave an introductory talk on Rails, then Paul King gave another talk, this time on Grails (the Java version of Rails,) and closing the morning session was Keith Pitty’s talk on Ruby for Java shops. For the afternoon, I followed Adam Kennedy’s talk on optimizing projects for wetware. For the closing keynote, Nat Torkington talked about the future of software: And with a day left before returning home, I went to sightseeing mode, bought a couple of books, and the mandatory pasalubong for the relatives. At midnight, my flight took me back to Bangkok, another long trip that touched down at the crack of dawn: After a few hours’ wait, I took the plane back to Manila, returning home just after lunchtime. This being my first international trip, making it alone seemed to be quite an adventure. But I wasn’t really alone in this endeavor: kudos goes to the UNDP International Open Source Network for their exchange grant program, to my relatives for their support, to Free and Open Source Software for really making things rock (and free ;), and to $DEITY for being there. Until the next trip!

It's an end of year tradition for non-profit organizations to do big fund-raising and membership pushes. As I mentioned several days ago, I am personally giving to two organizations this year: the Wikimedia Foundation and the Free Software Foundation. The FSF has a goal of 500 associate members by year-end and it's an important goal that will sustain the foundation's activities. While membership dues keep the lights on, the fact that the foundation has a robust and growing membership is equally, if not more, important. FSF executive director Peter Brown put an appeal online in both video and text versions. In it, he lays out some of the most important issues for the next year. You should watch the video version in OGG Theora or this YouTube version (requires Gnash or non-free Flash). The appeal briefly lays out the FSF's plans for next year. My partner Mika Matsuzaki and my friend Oliver Day shot and edited the video. Please pass the link around to those you feel might be interested. Here's my appeal:

Now is the time to join and give to Free Software Foundation. 2008 is going to be extraordinarily important year for free software. Eben Moglen likes to quote Gandhi's "first they ignore you, then they laugh at you, then they fight you, then you win" progression when describing the free software movement. As I pointed out when I joined the FSF board, we're beginning to see powerful interests fighting free software. It's going to increase in the next few years. Things will probably get a lot uglier for free software before they get better. We can win but things are far from settled. The FSF is the front-line organization in this fight and we need a robust and proactive foundation, and an active and involved membership, if we're going to win. Here are the issues that I'm going to pushing the FSF to pursue in the next year. Expanding activism outside our traditional technologist communities: In part through the work of projects like Defective By Design, we've seen the tide turn for DRM on music in what what may be the FSF's greatest success last year. I'm going to push the FSF to continue the campaign to attack DRM for video, eBooks, and the other places it is cropping up. The most remarkable thing to me about Defective By Design is that its participants and supporters are not, for the most part, people who develop or use GNU/Linux or even know what GNU is! If advocacy for software freedom involves a conversation we can only have with people who understand what POSIX is and how one uses it, we've already lost. Through DbD, BadVista, and other projects, the FSF has made major strides in the last year. It need to do much more and needs your support to do so. Get proactive about software patents: As a community, we've had our head in the sand about software patents for far too long. There are companies and patent trolls sitting on massive, growing piles of software patents. They are not our friends and they do not mean us well. One cannot write non-trivial software today without running a serious risk of infringing patents. The software patents minefield we've found ourselves in is a very fundamental threat to the success of free software and we've already begun to see the first casualties and costs. We must eliminate software patents. Now. The US is very important in this fight (much patent law is "exported" from the US) and almost no organization is working on software patent elimination there. Not enough people are thinking and acting strategically on this issue. The FSF is planning to make major steps in this fight in the coming year and we need your support to do so. Web services and the changing face of software: This last year, I worked to help launch the new version the AGPLv3. The license addresses the role of copyleft for software like web-services which, due to the legal particulars of the GPL, did not extend to the purveyors of web services. Of course, access to source code does not make the users of all web-services free (e.g., the GMails and the Facebooks). Nobody seems to know what freedom for webserver entails. There might not even be good answers. In the next year, I'm going to push the FSF to help start several conversation and to begin to follow up on what I think was an important first step with the AGPLv3. While this is not a major organizational priority yet, it's a major action item that I will be pursuing through the FSF. If you feel strongly about this issue, whatever your position, become a member, stay involved as these projects develop, and have your voice be heard. We don't know the answers yet and we need your input as much as we need your action.

Please, support the FSF in the efforts listed above, and in others, by giving generously. If you're not a member, please join the FSF as an associate member. If you are already a member, please consider making a tax-deductible donation. The FSF is a very lean, very humble organization of passionate and dedicated individuals working tirelessly for software freedom. Every little bit helps. Members pays USD $120 ($10/month) and student members pay half that. FSF has members across the world -- where a weak dollar often makes it even cheaper. Member support and participation builds capacity and credibility for the foundation and keep the organization responsible, responsive, and in tune with our community.

On Monday I was at a Vanessa Mae concert in arena “Riga” in Riga, Latvia. The concert was almost an hour late due to flight delay. It would have been fine if the organisers would let us into the hall or at least informed the several thousand people about the delay and its reason and not just have us stand in the rather restricted lounge. around half an hour after the planned start time, we were let to our seats and some ten minutes later an announcement was broadcasted explaining the reason for the delay. Vanessa came out with her own band and a local Latvian string orchestra. I wonder if she played with local orchestras in other locations as well. The orchestra preformed perfectly as far as I could tell, which is not much because they were mixed way down and were barely audible most of the time. I am a big fan of Vanessa Mae - I like classical music, I love her interpretation of that music and I appreciate how she made classical music more acceptable for a modern teen to like. That said, the concert was a mix of joy and disappointment for me. The joy came from hearing the music that I know and like and seeing how it is played in real life. It was a great joy and most of the time I was bobbing in my chair as a very happy boy. However, there were moments when I cringed and unfortunately there was more than a handful of those during the two hour concert. The problems could be put into three categories: 1. Vanessa missing a note or even a handful of them badly. I will be an optimist and blame that on the tuning - just the day before she was playing in Seatle in 80% humidity and then came to Riga and 20% humidity. She had to retune her wooden violin after each song because of that. She apologised for that mid-show. 2. Spotlight and camera missing the action. At times Vanessa steps back and one of her band members goes on a solo, but most of the time the person controlling the spotlight and the person controlling the camera were not ‘in’ the action and just stayed on Vanessa. The worst cases were when a couple seconds into the solo the camera would start to pan over to the band member playing the solo part, spend a couple more seconds framing and focusing and then after another second the spotlight did the same and by that time the solo part was over. Two cameras and two spotlight should be used for such cases with people controlling them having a clear idea of what happens next. One camera should always be on a wider angle shot and one for closeups, so that when a switch is coming, you could switch to wide angle a couple of seconds before the switch, give the closeup camera time to change target, re-frame and re-focus and then switch to it. And for the spotlights, one would always track the main person and the other seeking out the next person of interest. 3. Mixing problems. Vanessa was always way too loud and drowned out the other instruments even when that was not desirable. Background orchestra was too low. In general the mixing was very pop-ish - no dynamic range. The worst cases of this were Bolero and Storm. Storm is my favourite melody and I especially love the slow and quiet beginning of the song, but that was skipped entirely in the concert cutting straight to the loud part. Some other songs were also brutalised that way. I know that true artists generate most of their income through concerts and for that reason I recommend every Vannessa Mae fan to buy the tickets to her concerts, but if you are an audiophile .. don’t go there - stay at home with you trustworthy stereo system and FLAC recording of great sound. The concert is there to support the artist and for the atmosphere not for the best sound, unfortunately.

Following Lucas^[1] post about NM, I used his data to create the following two nice graphs^[2]. Both are the normalized datas of average count of people waiting for Front Desk, the DAM or their account. The first one does that on a 90 samples window (roughly 3 months) and the second one on a 180 samples one (roughly 6 months). This kind of smoothing actually eliminates high frequencies, hence we see what a usual behavior each step has. What is clear to me is that FD situation is clearly fixed for quite a long time. FD was definitely an issue one year ago, but it has been really really fixed: for more than a year, even on the 6-months smoothing graph that has quite a long memory, the average queue is around 3 people, I can't see how it could even be reasonably improved. Of course, given that the Keyring step is just after the DAM, and that people at those steps works in batches, the data is a bit biased, though it gives a pretty good idea of the bottlenecks of the whole process.

So much for KDE 4 ... after a lengty downgrade and package picking session (Yay! for dependency handling in Debian!) I'm now back to the trusted KDE 3.5.x (mostly x == 8) and will wait until KDE4 hits testing (which would be after lenny, I guess.) KDE 4 sort of worked - but I'd not call this &ldqupbeta%rdquo; at this stage, and apparently the KDE people joined the use-as-much-screen-surface-as-possible-for-funky-stuff crowd, leaving less space for actual application content than before. I hope the final versions can at least be configured to be smaller. I hoped the Live CD would be somewhat more complete than what's currently in experimental, but unfortunately, KDE wouldn't even start for me :-/ (Admittedly, I didn't fool around with it very long, so maybe it might have worked with some magic word.
