So I know, I know. There are a lot of annoying memes circulating on the net/facebook/[pick your spot] and well, sometimes the best thing to do is stop the damn thing by ignoring its existence. But I have to say, I have completely, totally and absolutely have loved reading the 25 things notes on facebook. It just provides a window into the extraordinary character that emerges from the collection of mundane events/likes/pleasures that make up people s lives. Reading them took me back to elementary school when and where I was an avid slam-booker. I have very fond of collecting and reading the tidbits of thoughts and information people left behind in my notebook. What also struck me about these recent 25 thingie notes is how odd or not as interesting, I think, it would be to have them recited to you over coffee or at dinner. Now I could be wrong here but I think the list-like quality would just not fly in a conversational context. A few facts with more embellishment would work but a whole string of thoughts would just sound flat and out of place. A reminder that format does matter for engendering certain types of knowledge. So here is my list.. 1. I looked like a boy for the first three years of my life (but a cute one, I think).
2. I love dogs so much that I often think that if I had a criminal streak, I would be a dog nabber.
3. I would routinely bring home dogs from the street when I was a kid. Many of them ended up dead after being hit by cars (they liked to return to the street and this only happened to 2 of them).
4. My favorite concert was Jimmy Cliff in a parking lot. There was lots of rain and lots of weed.
5. I like have a penchant for tall men. My mom claims it was because I lacked a strong father figure in my early childhood years. Who knows if that is the case.
6. I knew the instant that I took an anthropology class I wanted to be an anthropologist. I guess I made it happen (and it was one of the few moments of clarity in life).
7. I started the first environmental club in my high school and my car was called the recycle-mobile because there were always cans in the back seat.
8. I love the ocean; swimming, snorkeling, diving, sailing, and just watching it, though the cold ocean is not always by cup of tea.
9. I had terrible insomnia for a year and slept for a good chunk of it on a couch. I like the snuggle feeling I got from sleeping against a back.
10. I am very indecisive person. It is annoying as i tend to worry a lot about whether I made the right decision.
11. I was a shy kid and barely talked until meeting my best friend in kindergarten, Yael
12. I also failed the psychological test to get into school but my mom managed to get me in anyway.
13. I often wonder if I would have been a nun if I had lived prior to 1900s to escape various domestic obligations. I think it might have been fun to be a nun.. Fun to be a nun also has a nice ring to it.

14. I am currently struggling with an Etsy addiction and the UPS delivery guy asked if delivering packages would be a daily occurrence.. I just find all the stuff amazing and it brings me back to my artist days when I used to paint and spend a heck of a lot of time in the darkroom.
15. I have recurrent issues with nausea and have been hospitalized for it a few times. It is gut wrenching and really uncomfortable when it happens.
16. When I left NYC in 1997 I thought i would never come back. I am here now and quite happy.
17. I was obsessed with Ultimate Frisbee for many man years. I played more than I studied and finally gave up as it was ruining (or perhaps ruined?) my neck. I still miss it.
18. I LOVE tostones and would eat them everyday if they were not, you know, so bad for you.
19. I have been using IRC for 7 years and consider some of my best friends to come from there.
20. Some folks have asked how I became interested in politics and I am pretty sure it was Doonesbury.
21. When I was like 4 we went to some fair and I swore that I almost got flung off some rickety ride but this could be totally wrong. It was really frightening.
22. The coldest night of my life was spent in Los Nevados, Venezuela and the scariest car ride I ever took was leaving Los Nevados in a jeep and something that resembled a road.
23. A few sucker fish once tried to stick on me while I was doing a decompression stop after a dive. My dive buddy smacked the fish, which had devil faces, with the regulator, saving me from what would have been a really sort of sucky situation.
24. I am trying to learn how to surf and am really sorry that I did not do so when a teenager since I don t exactly have the time to really learn.
25. Since I am not sure how to end, I will do so with a

New day, new luck... and next try... ;-)

Today I received two emails with even newer BIOS updates for my problem. The second, latest version 1.80p did actually fix the problem of not booting with 4 GB of RAM. I haven't tried the first, previous version 1.80k yet, so I can't tell if that worked as well.

Anyway, despite the fact that the machine now recognizes 4 GB dual-ranked memory, Linux uses 3.1 GB of it - at least when not using Xen... But first without Xen, standard Debian 2.6.26-1-686 kernel:

Sadly, the machine gets so slow that it needs >20 mins (1100 secs) to boot. Most likely something is broken with PAE on this machine so it get's awfully slow.
I'm curious what the Asrock support will say about this!? ;)

Side note: I'm really satisfied with the good response from Asrock Support. Asrock might not be the company with the best mainboards available, but its support seems very good to me: very responsive and care taking!

Bruce Schneier is very sceptical about the new hard drive encryption standards released by a group composed of virtually all major storage vendors. He points out that the established software solutions have worked just fine, while this new standards adds complexity (and probably flaws, too) at the hardware level. I'm not so sure myself in which direction the balance goes:

• Encryption (without the key management, which I do not suppose the standard covers) is not that complex to get right and it can easily take advantage of hardware acceleration. (Yes, I don't quote numbers here. Schneier claims he hasn't had problems with encryption speed, but doesn't have numbers either ...)
• It should be a lot easier to subvert a software component than it is to subvert a hardware component.
• It is a lot harder to correct errors in hardware / firmware than in software and get users to apply the updates.
• In many cases the key management is the weak point, not the encryption itself. And key management is hard to get right regardless of where the encryption sits.
• I'm sure the abysmal track record of encrypted drives affects only the cheap USB drives and not the type of hardware we're talking about here. But, can I really be sure? (Serious) software solutions come from companies where security is the main business, whereas the hardware encryption will be implemented by storage companies which so far haven't had to care much about these issues.
• Finally: This standard should replace a number of proprietary solutions since some vendors already do offer encrypted drives anyway. Assuming the standard is sane, this should certainly be a Good Thing in any case.

In August I got a very nice HP 2510p notebook which is now my main system for development. This took a while for two reasons. First of all the system did not resume 100% reliably. This has now been solved, although the final patches needed for that will only be in 2.6.29, but that's no problem as I run upstream kernels anyway (I do quite a bit of kernel testing). Kudos have to go to Rafael J. Wysocki who has been doing a huge amount of work to improve the suspend/resume code in the kernel. Second of all I wanted a docking station so I could continue to use my 19" monitor, with the laptop's LCD as second display. I bought the docking station in December. The challenge then was to automatically (de)activate the external display when the notebook is (un)docked. Unfortunately there are no ACPI events, but the hp-wmi module (written by Mattew Garrett) sends docking events to the input subsystem. I wrote a small program to catch these events and a script that uses xrandr to switch displays. There were two issues with that setup. The first docking event was getting lost, but I managed to fix that. And the X server would crash when starting some applications (einstein and virtualbox) after undocking, but there's a patch for that too now. The notebook is now really well supported and stable.

• suspend/resume works completely reliably
• the docking station works nicely and so does the dual display setup
• wireless works nicely
• the SD card reader works (was used to develop support for MMC/SD cards in Debian Installer)
• the accelerometer works (so I can play Tux Racer and Neverball by tilting the notebook) using the lis3lv02d module, and Pavel Machek recently even added freefall detection, including example code to park the hard disk (targeted for 2.6.30)
• the fingerprint reader works, though I'm not sure I actually want to use that for logging on to the system

The system is currently running Debian/lenny with a KDE desktop and a 2.6.29-rc3 kernel. Working with upstream developers to get this far has really been worthwhile, and fun.

On Saturday (7 February), I should be attending both The Phone Co-op AGM and The Phone Co-op Members Workshop before it. I ll be asking a question at the AGM, if we can get the wording nailed down in time. Sadly, travel from Bristol to Chipping Norton by train is totally screwed by engineering works near Didcot and the usual poor connections from the cross-country line, so I ll be making a 2 hour car journey instead of a 5 hour train+bus combination. If you re travelling from the Bristol area and can car-share, please get in touch. Next Tuesday/Wednesday is Voice09 in Birmingham and I should be there if things come together in time. This is the Social Enterprise Coalition s annual conference. Conservative Party leader David Cameron MP will open as keynote speaker, with Liam Byrne MP, Minister for the Cabinet Office, opening on Wednesday. Would live-blogging or similar be interesting to people reading this? If you d like to meet up at either event, get in touch somehow - comments here, instant message, email, or phone. If you ve something you d like to send to either, also get in touch.

My home file server, Asterisk PBX, firewall and general router is apparently dying. I am looking forward to replacing it, because it s old and eats too much power anyway. Now I just need to figure out what to put in its place. Basically I need a low-power machine that ll be always on, with at least two LAN ports (three would be better, but I can also connect the cable modem with USB), and a means to connect at least two harddrives with at least 1Tb capacity. I d rather use SATA for the drives than USB, but I would be willing to investigate eSATA and external drives too. However, I want to have direct access to the drives and not be forced to use some sort of proprietary RAID. At the moment, I am investigating the Thecus N3200PRO, which has quite a reasonable hardware selection. The device has a low-power AMD Geode processor, but for some reason I have it stuck in my head that the ARM would be a better choice. Does anyone have experience with this device? Or maybe someone would like to make a different suggestion? Mail me! I d prefer a device that I can get working without too much learning or frickling. The less I have to learn/know about and touch hardware, the better. It would help if the machine booted off the harddisk, for then I could install Linux elsewhere and move the disks. Alternatively, network booting and a serial console would work, although I hear that USB makes that unnecessarily painful. I d like to avoid flashing ROMs or other black magic just to get it working. NP: AC/DC: Powerage Update: The folks at EXSYS kindly replied and filled me in with some information regarding the N3200PRO. Thanks! First of all, Thecus officially claims that it is not possible to install Linux on the device (although the device is running Linux, according to the hardware list). Second, the machine boots off a Flash-ROM, which makes the installation more difficult than I d like it, and apparently also one-way: once the Thecus firmware has been overwritten, there seems to be no way to get it back. I am looking elsewhere now, because even though the hardware is exactly what I want, I won t give money to a company who impose shackles on their customers and force them to use software that may not be up-to-date, and which is probably castrated I d be surprised if the N3200PRO spoke IPv6, for instance. Nevertheless, I ve asked about installing Debian in the Thecus User Group forum and I also dropped a message to Thecus itself. I ll keep this post up-to-date, so come back for more.

So for those of you, not going to FOSDEM, there should be streaming. :-)

For the sake of full disclosure: this is the first time streaming is officially planned at the FOSDEM Debian dev room, but so far maybe the worst prepared. So this announcement is probably a bit too brave...

But I thought I send it anyway. I'm quite very confident it will happen, despite my desorganisation atm (and the little time to set up and test on saturday). And as it would be very sad, if there were streaming, but no viewers due to lack of announcement of the streams, I decided to write this here.

The URL of the streams should be announced/linked on http://video.debconf.org but will definitly be also announced on our wiki page where we keep track of the volunteer shifts (for those watching at home, those times are UTC+1). Please enter your name in the schedule there, if you want to help us, we have 60 shifts to fill. (15 talks, 4 positions for each: 2 camera operators, video mixer, audio mixer.)

Watch this space :-) (Though a proper announcement shall also be send to the project mailinglist.)

Tim Skirvin sent me some enhancements to this script, so I took a moment to write documentation and put it up on my miscellaneous scripts page. This is my version of the integration script between git-buildpackage and pdebuild with cowbuilder. There isn't very much to it, but it does handle automatically adding the etch workaround option where needed and supports selecting the chroot in which to build via an environment variable. As usual for these sorts of little scripts, it hard-codes some of my preferences and will probably require modification to work smoothly in your environment. Unlike the larger packages I maintain, these random scripts are little things I use to speed daily tasks or obscure scripts for specific needs I have. I make them public on the outside chance that they'll solve some problem someone else is having or will serve as a useful example. Further updates generally won't be announced in my blog.

I'm supporting a class of high school students who are new to programming, and will be learning some python. Most of these students are comfortable with computers, but not hacker types, and few if any of them have written code before. I'm looking for an editor or an Integrated Development Environment (IDE) that won't be too scary for them, and will help them get used to the novel idea of writing code without simultaneously having to get used to the novel idea of an unfamiliar user interface. So i can't expect them to pick up my beloved emacs, for example. But on the other end of the spectrum, i'd hate for them to try to write python in an word processor (i've seen people do it!). Here's what i think i'm looking for:

• comfortable graphical interface -- these students have not used the command line before, and while they'll be introduced to the python shell, they should be able to write code and browse for files, etc. in the "normal" (sigh) way. This means, for instance, that tk-based interfaces are less good because they don't integrate with the common GTK-based UI.
• syntax highlighting -- the students will need to figure out what's a variable, what's a function name, what's an operator, what's a reserved word, etc. Visual indications like font-lock-mode from emacs would be really useful.
• whitespace management -- since python has syntactic whitespace, it would be great if there were convenient/intuitive ways for students to adjust the whitespace in their programs. Of course, it's hard to say what's going to be intuitive for other people. I like tab-cycling whitespace myself; are there other approaches i should be proposing?

Do you have suggestions for tools that work well for the above needs? Favorites? Are there features other than the "top three" i listed above that you think i should pay attention to? FWIW, they'll be working in a labful of machines running Ubuntu Hardy for the most part, but i'm willing to port and deploy programs (particularly ones that feel like a perfect fit) if they're not available in hardy.Tags: ide, python, recommendations, student

sorting text records on the first column only It turns out that join is a strange beast. Let's say you have two files, which are textual records using TAB as separator, containing different columns beside the first one, which is the record key. Using join you can do cool stuff like join file1 file2 to obtain a join in the relations sense, by default on the first column. The join manpage states that the two fields must be sorted on the join field. This is of course to avoid complexity explosion. The annoying thing is that if you forget to do that, you will miss tuples, without any warning, which is not good (and can actually be at least spotted avoiding complexity explosion ...). So yeah, if I'm here it's because after having been hit by this, I finally read the fine manpage But how to sort on the join field? Turns out that dear old sort -u file sponge file is not enough. Why? Because by default it will use all keys to sort and then you will end up sorting also on data values; needless to say that such sorting methods is not stable among the two different files you want to sort in turn. OK then, let's try with sort -u -k 1 file sponge file. Not even, but close. ... because sort with this syntax will start sorting at key 1 (which is the default), but then continue sorting with the other keys, in the hope of doing you a favour. The magic line is then sort -u -k 1,1 file sponge file, which tells sort to (damn) sort using only the first (damned) key and stopping there. Thank you sort. Have a nice day. PS I've been sick this week, but I'm definitely getting better, so I can finally announce that I'm going to FOSDEM 2009, yay, see you there!

Well, after getting some comments to my blog post I went today to the local dealer with my machine to test whether the board will be happy with 4 identical 1 GB DIMMs.
Long story made short: it isn't. Obviously it's the fault of the Asrock mainboard. Bummer.

So I'm stuck with just 3 GB of RAM. Thankfully the dealer took back the second new DIMM! :-)

Theodore wonders about LUG activity - well, I have been very active over the years in the Devon and Cornwall GNU/Linux User Group but the problem is that Debian (and more specifically Emdebian) is taking up the time that I used to put into the LUG. The LUG itself has remained very active, although geography means that meetings are actually difficult. The LUG continues to attract new members, existing members continue to contribute and learn new stuff themselves and a number of the long-standing members have joined free software organisations in their own right - including Debian. If there is going to be another DD in Devon or Cornwall besides myself, I'm pretty sure that the person will have been part of the DCGLUG before considering joining Debian.

I'm still webmaster for my local LUG, I get to some meetings although some do conflict with existing Emdebian meetings.

What do I get out of it? Local friendships and exposure to GNU/Linux issues outside Debian.

Debian can be a very insular world - we care about Debian, we talk about Debian, we get together as Debian but sometimes we lack comparative input. We don't really know how we compare with other operating systems and other distributions at a user level. Debian Developers, in particular, can easily lose touch with ordinary users of other systems. Debian, for me, is also a distant world geographically. I live a long way from other DD's in the UK who gravitate towards Cambridge, 300 miles away. It's just nice to have people within 10-50 miles, people I can contact about hardware issues and who have just the part I need because they kept it "just in case".

I still contribute on the LUG mailing list, although my contributions are generally related to licences, avoiding non-free rubbish and issues around embedded devices. I'm not as active as I'd like to be or as I have been in the past but I still want to be part of the LUG.

Yesterday I merged a patch from weasel into our dak repository. We are now generating a mapping between a package and the associated files on our mirrors. While the initial customer for this is a new snapshot.debian.org implementation, it might be useful for others too. If you want to have a look at it, it is on every mirror, file indices/package-file.map.bz2. The entries are plain rfc2822 format and currently have the following information:

• source packages have the keys
  • Path pathname on mirror
  • Source the source package
  • Source-Version the version of the source it belongs to
• binary packages have the same ones as above, plus
  • Architecture the architecture this file belongs to
  • Binary the binary package name
  • Binary-Version the binary package version, which can be different than the source version.

It currently doesn t make any difference for suites, but if that is needed it could be added, i guess. Well, one could also look in the suite-*.list.gz files in files/components and take that together with the above to get this info. (And yes, you could get this information by parsing all Packages and Sources files of all suites. I bet you will waste way more cpu time, coding effort, whatever, in doing that. :) ) Anyway, whenever you need something like this, don t hesitate to ask. Especially not if you yourself get us the code for it. :)

One of the most frustrating things about Copyright Expansion is that it s being driven through at international levels, far away from most of the people that it affects. When we try to contact our international representatives, such as national government ministers or officers, or Members of the European Parliament (MEPs), it usually takes me at least two attempts to convince them that I actually understand the issue that I fell they re about to bodge. So, here we go again:-

The European Parliament is being asked to nearly double the term of copyright afforded to sound recordings. Industry lobbyists suggest that extending copyright term will help increase the welfare of performers and session musicians. But the Term Extension Directive, which will be voted on by the Legal Affairs Committee in a few weeks time, will do no such thing.

Follow developments on EDRI s Copyright page and Write to your MEP, like Stuart Langridge did. I ll contact Neil Parish MEP directly and hopefully he ll remember me, so I won t have to do that stop sending me copy-pasta from Malcolm Harbour dance. I ll also see if I can get nice responses out of the other parties this time.

I've been meaning to try NoMachine NX for a while. Its promise of fast remote X11 sessions sounded exactly like what I wanted to log into my work desktop remotely (I really like having a remote desktop with saved state you can just pick up from when using remote access). That was pretty much all I knew about the software, so I was a completely blank slate. The getting started guide is the perfect example of how not to write a getting started guide. Firstly, Section 1 - "Getting started" - gives me a full history of the product, goes into significant depth about the challenges of forwarding X11 requests, talks about the caching and compression implementation, round-trip latency measurement, the details of two-way proxying system and discusses every other feature of the software. My eyes glazed over after about the first paragraph. That's all great -- I just want to know what to do! At this point, I assume that I'm required to run some sort of daemon at the remote end. I download and install the server package (it is explained that the server package requires the client and agent packages as well, fine). I'm paging down, looking for something to get me started. I'm happy to see Section 7 - "Set up your NX Server environment" (remember, at this point I though I needed some daemon running in the background constantly). It even has some commands commands to type, so I tap away, running nxserver --useradd nxtest --system. My server binary doesn't even seem to recognise these options. I give up, assuming that the server isn't running and nothing will work. The getting started guide has abruptly ended and I have no idea what to do. As it turns out, it's all completely trivial. Here's the missing "getting started guide".

• Download and install the client, agent and server packages on the remote end. You need to have ssh access to this box.
• Install the client on your end.
• Run /usr/NX/bin/nxclient. It will start a wizard where you input the remote host name.
• The client will, under the hood, ssh to the remote end, open the tunnel it needs, start the server and do all the magic required to make things "just work". A remote desktop will appear.
• That's it!

Additional tips:

• It's easy to tunnel this connection (for example, if you have to bounce through a ssh gateway to your internal network). Do something like /usr/NX/bin/nxssh -o 'Compression=no' -L 2022:remote.host:22 -f -N user@sshgateway.company.com and then connect the client to localhost:2022. You don't want to compress this link, as NX is already doing it.
• The only way I can find to make a new session is to start nxclient with the --wizard command.
• Don't click "Disable encryption of all traffic" if you're tunneling. AFAICT this tries to redirect the client to a non-encrypted port, which obviously won't get through.

Other than the documentation, it really works as promised, making remote X11 usable. One really nice feature is that it is smart about the resolution of the remote desktop, filling up your local screen. Add to that you don't need anything setup but your normal ssh connection, and it's a great remote desktop solution.

Someone suggested the clever idea of counting IRC channel users as a metric to use for langpop.com, so I went ahead and gathered that data. Since this is the first month, there are a few glitches (I missed #fortran - sorry guys), and a thing or two to iron out, but I thought I'd go ahead and publish the new results. IRC counts towards the "discussion" portion of the stats, rather than the main part. Like everything else, it has its biases - I used the Freenode network, which is definitely more about free software than other places might be. One number that really jumps out is just how popular the Haskell channel is - it's right up there with all the most popular languages. It will be interesting to see if, over several years, all the "talk" about Haskell starts to translate into people using it for fun and for their jobs. I welcome comments on this post, but there's also a Google group I've set up for discussion of the results, data sources, languages, and so on: http://groups.google.com/group/langpop/ Another idea I'm kicking around is to create a separate page for "up and coming" languages, stuff like Scala, Clojure, F#... that kind of thing. It might have to use different metrics, because the newer languages often don't show up on many of the ones I use for the languages we currently have.

It has become a hidden tradition for me to watch Superbowl every year, despite disappointment in the game and coverage quality in the years before. It started as before: pre-game show, pre-pre-game show, coin toss show and kick-off show It is clear that the show is planned by and for advertisers and not for the viewers. That is a shame and a disgrace - the viewer must be the master of the TV programming and NOT the advertisers. In soccer the program starts, you see the captains exchange a handshake, you see the referee throw a coin and 10-15 seconds later the game is going full steam. Why do you need 3 ad breaks and 2 songs before the game is beyond me - get to the game! The camera work and NBC commentary is MUCH better than last year - stable shots with good close-ups and explanations that actually make sense even to people that are not American football experts. Oh and they actually use units - saying they won x out of y games this season and not they are x in y this season , mostly at least. The game had more fun than usual in the beginning, but the legal things slow it up again - it is weird that a guy got over the line but was called beck because of the knee touching and then a penalty for a false start ? Too much rules and regulations. Soon you ll have a team of lawyers on the sidelines and lawyer drafts will be more important than player drafts. And then again holding and chopping - isn t that what the blockers are supposed to do? Is that some kind of sissy sport? Maybe not. 100 yard interception return run I am speechless. Now that was a great, great play. That episode alone made watchig this thing worth it. Not the best sport thing I ve seen, but the best American football moment for sure. I like the basis of the game, it is a good game, but there is way too much fluff on it. That game needs to be cut down - less rules, less breaks, less interruption, less advertisements, less time to think and relax for the players. 10 seconds of play and 5 minutes of players chatting is not a sport, even curling has more action. The whole Superbowl should be over in 1 hour real time. If the TV transmission starts at 17:00, it should be done before 18:00. There is no content there to justify anything longer than that. Why is there a limited number of challenges? Do the referees make only a limited number of mistakes per game? No. Illogical. And when I though it was done and sealed, Arizona does a great drive and get a great touchdown. One more drive like that and the game could go either way. Now that is a good game. But again penalties spoil the whole game Fitsgerald gets a touchdown, another great play to turn the game around, but only because of the holding penalty giving Arizona safety score. Not deserving in my opinion. And the Steelers drive back AMAZING game! Now this is actually close to the best sports game that I have ever seen. I sure was not expecting that. And Arizona tries to drive back again. I was sleepy when I started to watch this, no sleep now. That was a great game. Despite all the commercialization, it is still a great game and it is very watchable if you download it from the Internet or watch it with TiVo and can skip the adds and the slow parts.
