Another attempt to shorten my list of movies where not having seen them makes me an absolute philistine, according to various friends: Papillon, with Steve McQueen and Dustin Hoffmann. Ignoring the tragic history behind it (the French penal system in French Guiana during the colonial era I didn't know about this from school), it's great entertainment. There is a kind of happy end, but nowhere close to what Hollywood does to its stories these days... A long time on the to watch list: The Fifth Element by Luc Besson. I don't know why but I had always been sceptical if I'd enjoy this one, but my feeling was completely wrong. Real fun. While I think the basic idea of superheroes getting older and having a midlife crisis, or a daughter, (and of course during the film, getting back into action) could make a wonderful film, the ending of Watchmen left me with a bad feeling about the whole film. But then I never read or watched superhero cartoons anyway, so maybe it's just that I'm not the intended audience for this one. Finally, V for Vendetta is another interpretation of the 1984 theme (actually, it's the interpretation of a graphic novel, but I've not read that), with a very well chosen John Hurt as Big Brother (or, I should say, High Chancellor Adam Sutler.) With quite a few slapstick moments, this isn't really as dark as the theme might suggest.

I got involved with open-source software before I learnt about software development in a university course. Naturally, when my profs tried to teach the waterfall model to me, I couldn t take them too seriously back then. After all, requirements specification design implementation verification maintenance is not really in line with the principle to release early, release often. Furthermore, since water cannot flow uphill, the waterfall model fails to represent development cycles, as they naturally appear, even in behemoth, ancient software nightmares. And yet, when embarking on a new project, I do tend to find myself first thinking about the big picture, instead of churning out the code. I am certainly not the best coder out there, and it might well be that I could benefit from learning to break down problems to get an earlier start on the implementation of components. However, I maintain that avoiding the waterfalls and engaging directly in extreme programming, agile software development, or pair-based approaches right away is not the answer. Rather, the best approach should probably involve a certain level of conceptualisation before code is produced. I am a big fan of test-driven development, and I like the scrum method for the very reason that it involves talking and challenging ideas (although I wouldn t follow the method down to the book). I like to think about trickles in the mountains where water droplets joyfully jump around. * * * When Glyn Moody spoke in his LCA2010 keynote about challenges we (as in society) face, and how open-source seems to have many answers, he dropped the following gem, which spoke right to my heart:

Twitter is the release early, release often principle applied to thinking.

By this simile, journal articles are produced according to the waterfall model. This may well be why they are usually outdated at the time of publication. Microblogging (like Twitter), on the other hand, is primarily used to publish stuff before it s ready, and which would never be published otherwise. With journals on one end, and microblogging on the other, I think the epiphany is found in between as with software development: web logs web applications that allow for easy publishing by anyone (which is a different problem not to be discussed here). Since articles on those platforms usually have at least a title and a body, they require just a little bit more thought than 140 characters of contracted brain farts, spilled into the world faster than it takes one to stand up, stretch, and sit down again. * * * Microblogging seems to be in line with where we re heading: more information, more self-promotion, more access to more people, and all that with lower barriers of entry. It s hard to argue against a trend, but I think we ve taken a wrong turn somewhere. The one specific instance of content is no longer relevant, and there is no more time in the day to read elaborate treatments of subject matters. Instead, what seems to prevail is a constant flow. This flow threatens to replace actual thinking and discourse, both of which require reflection and time a scarce resource used up by ever new, fast-flowing media. It seems to me that those who immersed in this flow are unable to get out, as if sucked in by a maelstrom. I ve seen people enter serious withdrawal within hours of not knowing what s going on in the world. One could miss out on something. If you re following people on one of those microblogging platforms, I challenge you to spend the weekend offline and when the urge hits, ask yourself what you are actually missing. I mean what you are really missing, and by that I mean anything other than the cozy buzz and hum of entertainment washed upon you, preventing you from having to think about what you could be (actively) doing instead. I hope it s not a lot. For else, I fear that this means that future generations will be stuck with this communication culture, just like water droplets can t ever play in the mountain trickle again.

Audio information can be stored in a wide variety of formats, which vary in sound quality, file size, compatibility, etc. There are lots of extensions that cannot be read by some players. For this reason, many audiophiles are often confronted with compatibility issues. There are lots of audio conversion tools available on the web, but there are much more formats out there than they support. Most converters support only a few extensions and therefore they fail to satisfy users requirements.

Finding a high quality mp3 converter
has long been a challenge. Happily, software developers have designed Factory Audio Converter. It converts audio files to MP3, WAV, WMA, OGG, APE, MP4, FLAC, MPC, AAC. The array of input formats is even broader: MP3, RA, RMM, RAM, RPM, RM, RMVB, WAV, OGG, CDA, APE, APL, MPC, MP+, WMA, FLAC, AAC, M4A, MP4, TTA, OFR, SPX, WV, XM, IT, S3M, MOD, MTM, UMX, AMR, MP3/OGG compressed MODs, MIDI, VQF, AU / SND, PAF, IFF, SVX, WAV, SF, VOC, W64, MAT4, MAT5, PVF, XI, HTK, CAF. If you are looking for a flexible audio conversion utility, this one is the best!

Good audio converters feature batch mode. If you have a lot of wma files and would like to save them as mp3, you need a fast-working and powerful wma to mp3 converter. Factory Audio Converter can convert hundreds of files within seconds. If you have gigs of music on your PC, you can set the utility to convert all of them and turn in. You will get up in the morning to see all your files saved in your preferred format!

By aid of Factory Audio Converter, you can convert wma to mp3 right from the desktop. Once installed on a PC, the program integrates into Windows seamlessly, and Convert to option appears in the right-button menu. All you need to do is right-click on a wma file and select Convert to. You can also run Factory Audio Converter from within other programs via command line.

Advanced users do not only want toconvert wma to mp3
. They want to do it easily! User-friendliness all but heads the top-importance list of characteristics. Factory Audio Converter has a robust and intuitive user interface. It does not take any background to understand how to use it. The program wizard will guide you through the whole procedure. It will help you select your settings. You may either skip it and leave the default settings or specify your own settings. Sound quality will depend on your choice of bitrate, samplerate and channel.

The more new features a program has, the more likely it is to enjoy demand. Factory Audio Converter incorporates a built-in audio player and CD ripper. You can listen to your tracks prior to conversion and compare output and input files. The CD ripper will rip your CD files and help you save them on any type of hard drive. Factory Audio Converter permits you to change wav to mp3
and save a lot of drive space. Now you can use any portable player and listen to your favorite musicians any time, wherever you are!

You can buy Factory Audio converter at a price comparable to that of any other converter. However, few converters are comparable to Factory Audio Converter in terms of user friendliness and productiveness. <script class="owbutton" src="http://onlywire.com/button" title="My Friend Audio Business Converter Product" type="text/javascript" url="http://www.imbrandon.com/2010/02/05/my-friend-audio-business-product/"></script>

Work doesn't often send to me places as great as Manilla in the Philippines, but here I am. It's a reasonably modern place and to me feels more like America than Asia in so many ways, posssibly because of its history. One thing is for sure, noone follows road rules here. Red lights are a suggestion and a zebra crossing is just some painted lines that you do need to stop at.

As for food, it's not that different, in fact this sad lot is about what was different:

• McSpaghetti - Was supposedly sugar coated spaghetti but actually was very tame, my son would of loved it.
• Wow Steak from KFC - Neither Wow nor Steak, like a big chicken nugget with gravy and rice
• Halo Halo - A dessert drink which was sugared or preserved fruit, milk and ice.

Generally though the food has been pretty good but nothing I could get at home.

Good news about Gjay, the previous maintainer said it was ok for SourceForge to hand over the control of the program to me so I've set it up in git and started working on it. Most of the work was getting the code up-to-date to the later gtk APIs and making it work with audacious instead of xmms. It's almost ready for (re)initial release and there is even an ITP ready to go.

Git is a rather interesting and new (for me at least) version control system. I've been using cvs for more years than I'd care to think about and svn but while it is a bit different as you'd expect I haven't had it get in my way. In fact I've been so impressed with Git I have put a few other projects into it, mainly with the collab maintence Debian project for a few of my packages.

In a couple of weeks at FOSDEM, I ll be giving a talk in the GNOME developer room on the semantic desktop and showing the new world of interaction that RDF, SPARQL and Tracker make possible. I ll be joined by Philip Van Hoof and Roberto Guido. We ll be digging behind the buzzwords, explaining what it s all about and most importantly showing off cool real-world apps using this stuff. We ll also announce a competition for the coolest app using Tracker and RDF, for which Codethink will sponsor a prize. See you all there!

The following was written by Stefano Cosentino in regard to the ongoing efforts of the Australian government to censor the Internet with protecting the children as an excuse. All these Internet filtering ideas that have been in the news lately has made me voice my own opinion on the matter as a non-expert. I m an IT advisor. I take someone s problem and help them fix it. I have a few clients who provide laptops to their students, everything is done with these laptops. The students have no books. The school provides laptops to their primary school students as well as their high school students. They have done this long before the public system started to hand out laptops to a select number of high school students. When you provide a child with anything, there are always areas where a child will find that you may have overlooked. In fact, a young kid will probably find a host of things that you might have totally missed or didn t ever know about. One of these things is the inappropriate nature of information you may find that are associated with computers. This can be anything. But specifically, what the filtering argument has been about has been leaning towards Internet pornography and I would imagine, more specifically content of a pedophiliac nature. I m not against child pornography being banned or filtered. I personally think this is one of the most cruel, inconsiderate, disrespectful and self centered behaviors a person could display. Their psychological makeup isn t the scope of this article. However these ideas must be conveyed when discussing the Internet as a modern technological device that can be used for both good and bad. The primary school students that I attend to aren t very interested in this stuff and as it has been mentioned long ago by others who have joined this argument, are more interested in online flash games that include characters such as Ben 10, Pokemon and Yu-Gi-Oh. When I m called in to scan these computers during the school holidays and hand the laptops back to the kids or when they get handed back after 3 years for new ones, I find that the older primary school kids computers are usually more prone to the adult orientated content. To me this is the first sign of a filter s failure. This customer of mine spends more money on the filtering devices they use on campus than I charge them for a few days of work. Does it work? Sadly, I hate to report that no, it does not. It s completely useless. The kids still have files and traces of files on their computers that isn t suitable for young children. Not only pornography but also content of a violent or morbid nature. As young and impressionable people, everything they read, see and hear is absorbed. This shapes the way society will become in years to come. Since no one can realistically tell the future, wouldn t it be nice if we could make sure that the people looking after us and our lives forty or fifty years from now have a sane mind free of blemish? It s a different story for the high school children. While scanning their laptops I have to contact the police on a daily basis because of the nature of the content I find during my day. Some things you can let slip, today s version of a pinup girl, or a provocative pic of whatever skimpy clad girl the record companies are flogging off these days as musicians. But sadly that s rare. I won t go into detail of what I find on these laptops of 14 year old boys, but it ranges from some innocent growing up curiosity right to perverted, sick and most if not all of the time, illegal content. The filters fail again. The kids find a way around it. And they find it easily. I ve seen filters work and not work at all with young kids right through to young adults. All the filters do is either hinder the poor kids actually trying to do research of scholastic nature or prolong the inevitable and temporarily block a determined child s interest in the search for some adult related material. The filter might prevent accidental viewing but it doesn t stop the deliberate finding of pornography and other illegal content. How does a filter stop this from happening? How does a filter stop a child taking their parents adult videos and copying them to their laptop or finding dad s stash of Penthouse? How does it stop a school mate bringing this stuff to school to show everyone at lunch time or to trade for other content they found by other means. Remember back to when you were their age and caught a glimpse of your big brother s room wall. How many times did you try and catch a peak at that Samantha Fox poster hanging off the wall? Where s the filter now? Here s some thing to think about. The filter shouldn t be a thing, it should be a person. They re called responsible . They re called parents. What priorities do parents have if their child feels that what they look at online that is of an adult nature is acceptable? Or maybe the kid knows better, knows it isn t acceptable but still goes out of their way to get the stuff on their computer? Sneaker Net still exists, USB memory sticks are cheap and can now have two or three straight DVD rips on them, or perhaps five or six encoded films on there. Hundreds and thousands of images and so on. Filter failure again. When the kids go online, they know of the technology used to block them from gaining access to what they want to see. Chances are, they ll know what a proxy server is and does. Then they ll figure out what they need to do to get around the filter. I, myself did this back in high school and TAFE when I couldn t find photographs of a particular device I was researching. Turns out the name is also a form of sexual activity, in another language, but still. The filter stopped me from not only looking the offending content but also to look at the legitimate data that I needed to complete an assignment. I got around the problem by researching some more information and the following day I was breaking through firewalls and proxy servers with easy. Filter failure. How do I get around this issue when speaking to younger kids that need guidance and knowledge on how to deal with this situation? I hold talks at the school I provide my services to. I talk to the parents, no kids. The talk costs less than a broken filter they keep throwing money at keep up-to-date. The school puts these filters in place to appear responsible, because while the kids are attending their school, the school is in fact responsible. In fact, there is nothing more the school can do. They could educate the children, but you can tell someone what to do, and the chances of them doing it are pretty dismal. Music is not allowed on their computers either. Yet we constantly find iTunes on there and a host of music that traces to certain peer to peer applications where they acquired the stolen music. If a kid can learn how to do that, imagine what sort of influence can be placed on them from a more positive angle. Like maybe parents providing an explanation for starters of what it is they re looking at. What it is they ll find online. What material is inappropriate. What material should you tell an adult about. Why do I get stupid emails with Russian girls wanting to marry me. Kids absorb everything. Parents have relegated responsibility but not delegated it. This filter idea might help slow down a child s enthusiasm to learn about everything, both good and bad. But educating the kids from an early stage in life about morals and the modern world where lets think about it, we have absolutely everything we need and want at our finger tips will be more valuable than any filter. But the fact that we have so much available makes it difficult to say what is and isn t appropriate for a child to see. It is up to us to inform the children of what s out there is the world. It may or may not stop them from seeing the adult related content, but it will help them respond to it in a mature and adult manner. We all know, kids aren t stupid. So, if the filters worked, why am I called in once a year, every year to give my talk to parents?

While I was under snow last week, the world saw a flurry of Koha company news. We found out that PTFS is to acquire LibLime and ByWater Solutions and BibLibre are partnering for the U.S. With the past ByWater Solutions and PTFS, Inc. partnering, it seems like four of the younger Koha companies (established 2005, 2007, 2008 and PTFS started with Koha in 2008 I think) are now linked together, so it s not entirely surprising that ByWater congratulates PTFS on the purchase of LibLime. What did surprise me is the impressed with PTFS s resources quote from Liblime owner Josh. Some librarians are asking What will the acquistion of Liblime mean to Koha libraries? but I m wondering what does this mean for the Koha project? Well, there s still our co-op (established 2002) and the other older private Koha companies (Calyx, Katipo and so on), as well as the rest of the younger ones, so I think there s still the motivation for a vendor-neutral non-profit group to host the project. Recent history has shown that it s too painful if any one private company hosts it. It ll be interesting to see how the recent private company deals help that work. If all goes well, a bright new day for Koha, as wizzyrea hopes. On another level, I m a bit disappointed that a theoretical Free and Open Source Software player (even if things like LibLime Enterprise Koha had muddied the water) has been sold to a mixed FOSS+proprietary player. I m almost cross with Liblime s owners for selling up, but I don t know if that s fair. Selling up is a fairly common exit move in private companies, so shouldn t I expect it? Do librarians expect it? Is this why some seem reluctant to buy from start-ups which are still independent? As you may know, TTLLP software.coop is in common ownership, so we can t really be bought. This is a self-defence or legacy-guaranteeing mechanism for our cooperative, where our assets are pledged to other common ownership cooperatives if our corporation dies. I think it also has the fringe benefit that we re a fairly safe home for things like trademarks. This unbuyability means that I feel I m watching the sales and cross-linking of our competitors from the sidelines, from a viewpoint more like Koha users than the other vendors, waiting for the dust to settle and the chips to fall where they may. Whatever happens there, software.coop will still be here. Unsurprisingly, there have been a couple of new entrants into Koha support, although the Liblime-controlled Koha project website doesn t show them yet and reportedly its new support company submission form has been broken for weeks, which is irritating. Interesting co-op-y things are happening in the wider library systems world, too, with Karen Coombs going to work for the OCLC library cooperative and Polaris Library Systems workers buying the company although I m not sure yet if they re becoming a worker co-op or merely employee-owned. I suspect many of these announcements are timed for #alamw10 which is a big US library conference. Has anyone seen more co-op or Koha announcements which I haven t spotted in the conference PR flood?

I've had alias net-pf-10 off and alias ipv6 off in my configuration for ages, but with recent kernels, IPv6 is apparently compiled in, so my eth0 now has a (link local) IPv6 address. ... which means that I now had Java apps suddenly fail to connect to the database. Since stuff like sqlplus (Bah!) works, I didn't immediately think about a network problem and started testing various JVM versions and hunting missing libraries etc. Only, it turned out that running java with -Djava.net.preferIPv4Stack=true is the magic bullet. Is there a proper fix? I know IPv6 is (supposed to be) the nice and shiny future, but currently I just don't have any IPv6 connection so it just creates problems for me right now. (Ok, let's add here that I dislike Java anyway because its philosophy, or the philosophy of most software I have to deal with, is to define its own world instead of integrating nicely with the host platform. If you look at it from another direction you may think I should have titled this I suck )

Yes, aptitude can list packages by priority, but what I wanted was a simple list of just package names. I've got two ways of getting a bare list:

Updated with many thanks to Phil Hands.

$ aptitude search '~prequired' sed -ne 's/^i [ A] \([^ ]*\).*$/\1/p' tr '\n' ' ' sort -u fold -s ; echo

#!/bin/sh
# Licence: GPL-3+
FILE= find /var/lib/apt/lists/ -name '*unstable*Packages'
LIST= grep-dctrl -n -s Priority '' $FILE sort -u

for P in $LIST; do
[ "optional" != "$P" -a "extra" != "$P" ] continue
echo "Priority: $P"
grep-dctrl -n -s Package,Priority "$P" $FILE sed -ne '/^'$P'$/!h;/^'$P'$/ g;p ' tr '\n' ' ' fold -s
echo
done

The advantage with the script is that is lists all packages in all priorities except optional and extra and can be restricted to individual Packages files and therefore to individual repositories and components. (Change the find expression if you have more than one repository specifying unstable or adapt the script to accept a path to the relevant Packages file on the command line.)

I really ought to have used perl because pattern matching in perl is a
lot more natural to me than using sed or awk. I do tend to chain a
couple of sed commands, just so that it's easier to work out which bit
is broken when it breaks.

The final version of this script will end up in emdebian-grip-server,
converted to perl with POD content, translated and reading the Packages
files using Debian::Packages::Compare.

Hmm, next step is to check the "Priority: standard" set for Emdebian - it looks far too large for what would be standard on an embedded device. LDAP will be dropped for one - and what is a -dev package doing in there? libunwind7-dev isn't even installed on my amd64 Debian desktop!

Probably check the important and required listings too, then tweak what we need to change via the archive overrides for Emdebian Grip.

Come to think of it, I might need a PHP version of this to read live data from the repository, documenting the changes.

I can hear the question now: What kind of guy puts The Iliad and War and Peace on a list of things to read for fun? Well, me. I think that reading things by authors I ve never read before, people that take positions I haven t heard of before or don t agree with, or works that are challenging, will teach me something. And learning is fun. My entire list for 2010 is at Goodreads. I ve highlighted a few below. I don t expect to read all 34 books on the Goodreads list necessarily, but there is the chance. The Iliad by Homer, 750BC, trans. by Alexander Pope, 704 pages. A recent NPR story kindled my interest in this work. I m looking forward to it. The Oxford History of the Classical World by Boardman, Griffin, and Murray, 1986, 882 pages. It covers ancient Greece and Rome up through the fall of the Roman empire. The Fires of Heaven (Wheel of Time #5) by Robert Jordan, 1994, 912 pages. I ve read books 1 through 4 already, and would like to continue on the series. War and Peace by Lev Leo Nikolayevich Tolstoy, 1869, 1392 pages. Been on my list for way too long. Time to get to it. Haven t read anything by Tolstoy before. The Politics of Jesus by John Howard Yoder, 1972, 2nd ed., 270 pages. Aims to dispel the notion of Jesus as apolitical. An Intimate History of Humanity by Theodore Zeldin, 1996, 496 pages. Picked this up at Powell s in Portland on a whim, and it s about time I get to it. The Myth of a Christian Nation: How the Quest for Political Power Is Destroying the Church by Gregory A. Boyd, 2007, 224 pages. An argument that the American evangelical church allowed itself to be co-opted by the political right (and some on the left) and argues this is harmful to the church. Also challenges the notion that America ever was a Christian nation. Daily Life in Ancient Rome: The People and the City at the Height of the Empire, by Jerome Carcopino, 2003, 368 pages. I ve always been fascinated with how things were on the ground rather than at the perspective of generals and kings, and this promises to be interesting. Slavery, Sabbath, War, and Women: Case Issues in Biblical Interpretation (Conrad Grebel Lectures) by Willard M. Swartley, 1983, 368 pages. Looking at how people have argued from different Biblical perspectives about various issues over the years. To the Lighthouse by Virginia Woolf, 1927, 252 pages. I can t believe I ve never read Woolf before. Yet another one I m really looking forward to. Tales of the Jazz Age by F. Scott Fitzgerald, 1922, 319 pages. Per Goodreads: This book of five confessional essays from the 1930s follows Fitzgerald and his wife Zelda from the height of their celebrity as the darlings of the 1920s to years of rapid decline leading to the self-proclaimed Crack Up in 1936. Ulysses by James Joyce, 1922 (1961 unabridged version), 783 pages. The Future of Faith by Harvey Cox, 2009, 256 pages. Per Goodreads, Cox explains why Christian beliefs and dogma are giving way to new grassroots movements rooted in social justice and spiritual experience. Heard about this one in an interview with Diane Rehm. Being There by Jerzy Kosi ski, 1970, 128 pages. Jesus: Uncovering the Life, Teachings, and Relevance of a Religious Revolutionary by Marcus Borg, 2006, 352 pages. Whether or not you agree with Borg, this has got to be a thought-provoking title. The Three Musketeers by Alexandre Dumas, 1844, 640 pages. The Book of Tea by Kakuzo Okakura, 1906, 154 pages. Per Goodreads: In 1906 in turn-of-the century Boston, a small, esoteric book about tea was written with the intention of being read aloud in the famous salon of Isabella Gardner. It was authored by Okakura Kakuzo, a Japanese philosopher, art expert, and curator. Little known at the time, Kakuzo would emerge as one of the great thinkers of the early 20th century, a genius who was insightful, witty and greatly responsible for bridging Western and Eastern cultures. Nearly a century later, Kakuzo s The Book of Tea is still beloved the world over. Interwoven with a rich history of tea and its place in Japanese society is poignant commentary on Eastern culture and our ongoing fascination with it, as well as illuminating essays on art, spirituality, poetry, and more. More of my list is at Goodreads.

I started to write this review last night, and went looking for Wil Wheaton s blog, where many of the stories came from, so I can link to it from my review. It was getting late, I was tired, and so I was a bit disoriented for a few seconds when I saw my own words flash up on the screen. At the time, his most recent story had excerpted my review of paper books. Wow, I thought. This never happens when I m about to review Dickens. And actually, it s never happened before, ever. I ll admit to owning a big grin when I saw that one of my favorite authors liked one of my blog posts. And Wil Wheaton is one of my favorite authors for sure. I enjoy reading others too, of course, but Wil s writing is something I can really identify with like no other. My parents were never in a London debtor s prison like Dickens were; I was never a promising medical student like A. C. Doyle. But I was, and am, a geek, and Wil Wheaton captures that more perfectly than anyone. After I read Just a Geek a few years ago, I gave it to my wife to read, claiming it would help her understand me better. I think it did. In The Happiest Days of Our Lives, Wil recounts memories of his childhood, and of more recent days. He talks of flashbacks to his elementary school days, when he and his classmates tried to have the coolest Star Wars action figures (for me: calculator watches). Or how his aunt introduced him to D&D, which reminded me of how my uncle got me interested in computers. Teaching himself D&D was an escape for the geeky kid that wasn t good at sports, as teaching myself Pascal and C was for me. Between us, the names and activities are different, but the story is the same. I particularly appreciated Wil s reflections on his teenage years. Like him, at that age, I often found myself as the youngest person in a room full of adults. Yet I was still a teenager, and like any teenager, did some things that I look back on with some embarrassment now. Wil was completely honest with himself he admitted crashing a golf cart on the Paramount studio lot, for instance, but also reminds me that he was a teenager then. He recognizes that he didn t always make the best choices and wasn t always successful with what he did, but isn t ashamed of himself either. That s helpful for me to remember; I shouldn t be unreasonably harsh on my 16-year-old self, and need to remember that I had to be a teenager too. I also identify with him as a dad. He wrote of counting the days until he could teach his boys about D&D, about passing on being a geek to his sons. I ve had a similar excitement about being able to help Jacob build his first computer. Already Jacob, who is 3, loves using the manual typewriter I cleaned up for him, and spent an hour using the adding machine I dug out on Sunday while I was watching the boys. (I regret that I didn t have time to take it apart and show him how it worked right then when he asked). And perhaps his 2nd-favorite present of Christmas was the $3.50 large-button calculator with solar cell power I got him as an impulse buy at the pharmacy the other day. He is particularly enamored with the square root button because a single press replaces all the numbers on the screen with completely different numbers! I can t find the exact passage now, but Wil wrote at one point about his transition from a career in acting to a career in writing. He said that he likes the feeling he gets when his writing can touch people. He s been able to redefine himself not as a guy that used to be an actor on Star Trek but a person that is a good author, now. I agree, and think his best work has been done with a keyboard instead of a camera. And that leaves me wondering where my career will take me. Yes, I m an author, but of technical books. Authors of technical books rarely touch people s hearts. There s a reason we read Shakespeare and Dickens in literature classes, but no high school English teacher has ever assigned Newton s Opticks, despite its incredible importance to the world. Newton revolutionized science, mathematics, and philosophy, but Opticks doesn t speak to the modern heart like Romeo and Jiuliet still does. Generations of people have learned more about the world from Shakespeare than from Newton. I don t have Wil s gift for writing such touching stories. I ve only been able to even approach that sort of thing once or twice, and it certainly won t make a career for me. Like Wil, I m rarely the youngest person in the room anymore. His days of being a famous teenage actor on a scifi series are long gone, as are mine of single-handedly defeating entire teams at jr. high programming contests. (OK, that s a stretch, but at the time it sure felt exciting.) But unlike him, I m not completely content with my niche yet. I blog about being a geek in rural Kansas, where there still aren t many. I m a dad, with an incredible family. And I write about programming, volunteer for Debian and a few other causes, and have a surprisingly satisfying job working for a company that builds lawn mowers. And yet, I have this unshakable feeling of unsettledness. That I need to stop and think more about what I really want to do with my life, perhaps cultivate some talents I don t yet have, or perhaps find a way to make my current path more meaningful. So I will take Wil s book as a challenge, to all those that were once sure of what their lives would look like, and are less sure with each passing year: take a chance, and make it yours. And on that score, perhaps I ve done more than I had realized at first. Terah and I took a big chance moving to Kansas, and another one when we bought my grandparents run-down house to fix up and live in. Perhaps it s not a bad idea to pause every few years and ask the question: Do I still like the direction I m heading? Can I change it? Wil Wheaton gives me lots to think about, in the form of easy-to-read reflections on his own life. I heartily recommend both Just a Geek and The Happiest Days of Our Lives. (And that has nothing to do with the fact that the Ubuntu machine he used to write the book probably had installed on it a few pieces of code that I wrote, I promise you.)

I usally find blog rants useless, but sometimes something is just so annoying one is sufficiently inspired. Today I went with my parents to buy them a Tivo at Harvey Norman, Norwest, Castle Hill, NSW, Australia. I am a big Tivo fan; the interface is good and it "just works". I don't mind paying for (or in this recommending paying for) good products. After selecting the Tivo model, I asked for a HDMI cable. The salesman made a series of questions about what sort of HD TV it was being plugged into; I quickly sensed this as a probe to see what sort of suckers we were, and requested just a "normal" cable. At this point, he insisted on a $130 (you guessed it) Monster cable, and had the audacity to say that we didn't need one of the really expensive cables because our TV wasn't good enough! I openly expressed my concern, but the annoying high-pressure sales pitch had just begun. The amount of, frankly, crap that he spewed about 4-bit this, 10-bit that, legislating of labels, DA signal levels, mythical customers who regretted buying the cheap cables and who knows what else was to the point of being comical if it weren't so insistent and said with such seeming authority. There is only one thing that matters - if the cable has passed the functional requirements for being certified to have the distinctive HDMI logo plastered on it. From the HDMI FAQ:

Q. What testing is required? Prior to mass producing or distributing any Licensed Product or component that claims compliance with the HDMI Specification (or allowing someone else to do such activities), each Adopter must test a representative sample for HDMI compliance. First, the Adopter must self test as specified in the then-current HDMI Compliance Test Specification. The HDMI Compliance Test Specification provides a suite of testing procedures, and establishes certain minimum requirements specifying how each HDMI Adopter should test Licensed Products for conformance to the HDMI Specification.

Now, I can understand that if you buy any old HDMI cable off Ebay for $1, it may be a knock-off that uses the HDMI logo illegally. But there is no way that the certified $50 Philips cable (still very over-priced, but at least not insane, and discounted to $35) performs any differently to some overpriced Monster model certified to exactly the same standard. The thing that annoyed me most was his analogy to buying a tyre. He stated that "if you walked up to a tyre salesman and I said don't want the Pirelli's, just put the cheap-o tires on my Ferrari" I'd be insane, and thus by extension of that logic I was insane for not buying a Monster cable for my great new Tivo. This analogy is completely flawed and really just dishonest. A Ferrari is much more powerful and goes much faster than a standard car. It is plausible it needs a better engineered tyre to perform adequately given the additional stresses it undergoes. A Tivo doesn't put out any more or any less bits than any other HDMI certified equipment, no matter what you do. If the cable is certified as getting all the bits to the other end under whatever environmental conditions specified by the HDMI people, then it's going to work for the 99% of people with normal requirements. Nobody wants to make a significant investment in a piece of audio-visual equipment and feel they are getting something that isn't optimal. Harvey Norman's use of this understandable consumer sentiment to sell ridiculously over-priced cables that do nothing is extremely disappointing. I'm sure the commissions on these things encourage this behaviour, so it is useless expecting the retailer or individual sales assistant to change their policy to reccommend reasonably priced cables. However, it is really Tivo and other manufactuers who get the raw end of this deal; a $130 cable is over 20% of the price the actual Tivo! That is surely affecting people's purchasing decisions. If Tivo and others included a certified HDMI cable with their device, as they do with component cables, and had "Certified HDMI 1.3 cable included" plastered on the box, it would be a harder sell to explain why the manufactuer would bother shipping a certified cable that is supposedly insufficient, and consumers would hopefully avoid the very distasteful high-pressure theatrics I was subjected to today.

Having excitedly bought an Arduino from the nice folks at tuxbrain.com while they were at DebConf9, I was then a little deflated to discover (while attending the UKUUG's Arduino Workshop in August), that the IDE is written in Java. While I can see that the authors might perceive this as the easiest way to provide cross-platform pointy-clicky-ness, JREs have a half-life of about an hour on my systems.Anyway, I fought with Java to show willing, until I'd determined that the IDE didn't seem to be happy running under xmonad (rendering menus so that they were unclickable) and gave up -- spending the rest of the tutorial proving to myself that I could compile and upload C code for the little beastie, but failing to compile Arduino sketches on the command line.Ever since, I've been meaning to work out the required CLI incantations, and finally made time over the weekend. The incantations turn out to be rather simple, if not very obvious, so I thought the world could benefit from a package that encapsulates the required knowledge.I've pared the source tree down to the c++ code and some examples and tweaked the Makefile so that it'll do it's work out of tree, referring to the files that the package installs for you, which allows you to apt-get install aurduino-core and then cut&paste a few lines from the contained README.Debian in order to get an LED blinking for the first time.The resulting git repo is now on Alioth. The binary-indep package it produces I've called arduino-core -- hopefully I've left enough room for any fan of the Java IDE to shove that back into the upstream branch and add packages for the full IDE, and maybe throwing in another package for the GTK IDE that's out there.I'm very mildly concerned by the fact that Arduino is a trademark of the Arduino Team, but that trademark is for the circuits, not the software, so this is probably irrelevant. If you think I should care enough to rename the package to freeduino, say, please get in touch.Anyway, if you have an Arduino (or similar) please grab a copy and test it.

Dan Gilbert gave an insightful TED talk about our mistaken expectations of happiness [1]. Don Marti has an insightful post about net neutrality and public property [2]. When net access requires access to public property then it should be sold in a neutral manner. Rachel Pike gave an interesting TED talk about the scientific research behind a climate headline [3]. The people who claim to be skeptical of the science should watch this. Mark Peters wrote an interesting article A Happy Writer Is a Lousy Writer about the correlation between emotional state and work quality [4]. Apparently watching a film about cancer will make people more careful and focussed on details. CERIAS has an interesting short article about Firefox security as well as some philosophy on why web browser security generally sucks [5]. Cory Doctorow writes in the Guardian about Peter Mandelson s new stupidity in trying to legislate against file sharing [6]. This is going to seriously damage the economy of every country that implements it. Charles Stross has been blogging a series of non-fiction essays about space colonisation, in The Myth of the Starship he describes how most ideas of space travel are bad and how the word ship is always going to be unsuitable [7]. Brent T. White is an associate professor of law at the University of Arizona who has written an interesting paper about mortgages [8]. He says that anyone who is underwater (IE owing more than the value of their house) should walk away. The credit damage from abandoning a bad mortgage apparently isn t that bad, and there is the possibility of negotiating with the bank to reduce the value of the loan to match the value of the house. Mako is working on a project to allow prisoners to blog [9]. It s basically a snail-mail to web gateway as the prisonsers are not allowed Internet access. PracticalEthicsnews.com has an article about the special status that homeopathy is given [10]. It also notes that homeopathic medicines include arsenic and mercury. Such quackery should be outlawed, a life sentence for homeopathy would be appropriate IMHO. Cory Doctorow wrote an interesting essay about why he is not selling one of his books in audio form (he s giving it away) [11]. He concludes by noting that he wants no license agreement except don t violate copyright law . The fact that he can t get anyone to sell an audio book under such terms is a good demonstration of how broken the marketplace is. Thulasiraj Ravilla gave an inspiring TED talk about the Aravind Eye Care System a program to bring the efficiency of McDonalds to eye surgery [12]. Hopefully that program can spawn similar programs for other branches of medicine and spread to more countries. In many ways they are providing better service (both in quality and speed) than people in first-world countries who pay a lot of money can expect to receive. Scott Kim gave an interesting TED talk about his work designing puzzles [13]. He is also a big fan of social networking, unfortunately (for people like me who don t like social networking) his web site ShuffleBrain.com relies on Facebook. Gordon Brown (UK Prime Minister) gave an inspiring TED talk about global ethic vs the national interest [14], with a particular focus on the global effort required to tackle the climate change problem. Now if only we could get Kevin Rudd to listen to that. Brough has written an interesting analysis of the AT&T network problems that are blamed on the iPhone [15]. His essential claim is that the problem is due to overly large buffers which don t cause TCP implementations to throttle the throughput. This seems similar to my observations of the Three network in Australia where ping times of 8 seconds or more will periodically occur. One particularly nasty corner case with this is when using a local DNS server I can have a DNS packet storm where basic requests time out while BIND uses a significant portion of available bandwidth (including ICMP messages from receiving ports that BIND has closed). To alleviate this I am now using the Google public DNS service [16] (the Three DNS servers never worked properly).

I guess I ve never been one to do things a certain way just because that s how they re normally done. I took my first college class pretty young, back in 1995, just after my freshman year in high school. By the time of my junior year in high school, I was well on my way through the computer science curriculum at Wichita State, and would probably have graduated from WSU at about age 20 had I not moved to Dallas, and then Indianapolis, for jobs. I did so because I (correctly) thought that in my line of work, experience was more important than a degree. However, playing into that was the incorrect notion that an education was useful primarily as a means to a career a notion that colleges and universities unfortunately have been promoting themselves. After moving back to Kansas, I started work to finish my degree I had effectively one year left had I been a full-time student. But it was difficult doing so, living almost an hour from Wichita, having a full-time job, and then when Jacob was on the way, I stopped classes entirely. Having online classes available to help me finish out the degree has been great. A year ago, I re-thought the value of education to me, concluding that there is a lot of value in education for its own sake. Looking at education as little more than a means to a career is the wrong way to approach it. Since I have had that re-evaluation, I ve adjusted my path even at this late point, and have enjoyed my classes more than I ever had before because of it. Graduating! So anyhow, here I am, graduating in a few days, 14 years after I started. I ve had some good news this semester, too: I ll pass the requirements to be a graduate of the WSU honors program, and also to graduate magna cum laude. So it may have taken me 14 years to do finish college, but at least I ve done it well . It feels weird to be about to be done with college, after so many years of being almost done, except for And a question I ve been thinking about a lot is: What next? Obviously I ll start by taking a break from college stuff. I want to be able to spend more time with Terah, Oliver, and Jacob, and there are things around the house that need attention. But after that? I figure I have a few options: No more college, but some reading. I do enjoy reading, and especially reading older works that are nicely out of copyright and thus free. I ve read few of the classics, but I enjoy reading them, and want to be better informed about them too. That could be fun. But sometimes it s hard to know how to place things in context. For instance, I don t think I could have gotten as much out of reading some famous philosophers as I did by doing so in a class that put them all in context and discussed criticisms of different positions. I also wouldn t necessarily have the ability to discuss and debate ideas with my classmates. Take the occasional undergraduate class in a topic that interests me. I m especially interested in history and literature, and haven t had much exposure at the college level in either. Various online courses are available from universities in Kansas on those topics. I could take a course or two each year and become a better-informed, more well-rounded person, and study an interesting topic at the same time. Maybe this would eventually lead to a degree, and maybe not. It would be fine either way. Graduate studies. It s a lot of work, and I m not sure it would be all that interesting to me. I ve looked some at curricula. I don t think that I m interested in computer science as a graduate program; I enjoy coding more than theorizing and analysis. But I also don t think that a graduate MIS or some such degree is for me; most of them appear to either focus on Windows or cover things that I ve already known how to do for years, and thus I wonder just what the point of them is (in addition to questioning how rigorous the curriculum is). I could also, down the road, pursue a graduate degree in something like English, philosophy, or history, but it seems a natural path to that would be to take more undergraduate classes in those topics first. So for now, I ll sit tight. I ll see how I feel by summer, how pressed for time I feel at home, and if I still feel the desire to take more classes. If so, I suspect I ll try to take some undergraduate classes in whatever sounds interesting to me at the time. In a way, that is quite freeing take a class on whatever topic I like, without a defined degree in mind. I ve never been free to do that before, and I like the idea of it.

On a recent trip up the Oregon coast, a friendly doorman at our hotel in Portland was inquiring about our trip. When we mentioned we passed through Bandon, OR, he quipped that Bandon was the place furthest from a city of one million people in the USA. I guess a normal person would just think "oh, that's interesting" and move on, but it has been plaguing me ever since. Firstly, I had to find what cities in the USA had more than 1 million people. Luckily Wolfram Alpha gives the answer:

• Chicago,Illinois
• Dallas,Texas
• Houston,Texas
• Los Angeles,California
• New York, New York
• Philadelphia,Pennsylvania
• Phoenix,Arizona
• San Antonio,Texas
• San Diego,California

(I certainly wouldn't have guessed that list!) From there my plan was to find the bounding box of the continental USA; luckily Wikipedia has the raw data for that. Combined with the latitude and longitude of the cities above, I had the raw data. I couldn't figure out any way better than a simple brute-force of testing every degree and minute of latitude and longitude within the bounding box and calculating the distance to the closest large city; the theory being that from one particular point you would have to travel further than any other to reach a city of 1 million people. Luckily, that is short work for a modern processor, and hopefully the result would be a point somewhere around Bandon. I'd already become acquainted with the great circle and measuring distances when I did Tinymap, so a quick python program evolved. However, it turns out that the program picks the far south-east corner of the bounding box. Thanks to the shape of the USA, that is way out over the ocean somewhere. I can't figure out a way to get an outline of the USA to test if a given point is inside the border or not, but all is not lost. I modified the program to output the the distance to the closest large city along with the location to a log file, and then imported it into gnuplot to make a heat-map. The hardest part was finding an equirectangular outline of the USA to place the heat-map over, rather than a much more common Mercator projection; Wikimedia to the rescue! I actually surprised myself at how well the two lined up when, after a little work with Gimp, I overlayed them (big) From this, I can see that Bandon, about a third of the way up the Oregon coast, is a pretty good candidate. However, probably not the best; I get the feeling the real point that is the furthest from any city of 1 million people is actually somewhere in the central-middle of Montana. However, we can also fiddle the program slightly to disprove the point about Bandon. The numbers show the closest large city to Bandon is LA, at ~1141km. Taking another point we suspect to be more remote; the closest large city to Portland (where we met the doorman) is also LA at ~1329km. So to reach the closest large city you have to travel further from Portland than Bandon, so Bandon is not the furthest place in the USA from a city of one million people. Myth busted!

Lil is white trash. She does not live in a double-wide and make hot dog casserole, and in foreign lands she could easily pass, but she is white trash nonetheless. Lyle is white trash. He does not buy potted meat or have a car up on blocks in his yard, but he is white trash nonetheless. One day Lil and Lyle met, and something drew them together. Perhaps it was a disturbance in the philotic web, or maybe a magical Jungian archetype of a dirty rag as a gas cap that resonated in their minds, but whatever it was, they decided to keep in touch online and get to know each other better, with clear non-platonic overtones. Lyle had a penchant for underdressed girls with a modest amount of tattooes and piercings and a full-on bent for drunken promiscuity. While Lil did not fit this stereotype well, she played up her sexual indiscriminateness and made up a few fetishes to impress him. Lil needed a boy who would not judge her for all her faults and long history of poor decision-making. So Lyle pretended not to judge. One-third deceit, one-third misinterpretation of Internet ambiguities, and one-third imagination led them to develop unrealistic perceptions of each other. Since they also had unrealistic perceptions of themselves, were fairly narcissistic, and were almost totally caught up in their own private melodramas, it took a while for the veil to come down. Come down it did, like an avalanche of Kraft Dinner boxes falling off a Canadian supermarket shelf. Then they were angry. Then they were sad. Then they brushed on fresh new coats of self-delusion and heated up some chicken nuggets.

Yesterday, the German magazine freeX published its December issue. It includes an three-page article about vbox-sync, written by me, that is even mentioned on the cover page. After my article on the Cross-Site-Authentication attack that was published in the German Linux-Magazin and the international Linux Magazine in 2005, this is my second publication.Vbox-sync is a tool to distribute VirtualBox images via apt-get that Phil Kern and I wrote as part of our work for itomig.de, a German Free Software consulting company, and the LiMux project. I also held a talk about it at the Debian Conference in Extremadura, Spain, in 2009.
