Lawrence Lessig interviews Jack Abramoff

Posted by Chris Ball Sun, 11 Dec 2011 21:20:00 GMT


Last week I went to the first in a new series of events called "In the Dock" -- Harvard Law professor Lawrence Lessig interviewed Jack Abramoff on the topic of Abramoff's illegal lobbying in specific, and the state of corruption in US politics in general. I took some photos (CC-BY-SA 3.0), you can watch a video of the talk here, and my friend Ben Schwartz also has a write-up including some great quotes.


I went in willing to detest what Abramoff had done, and him by extension -- and it's not that I ended up liking or trusting him, or that I was unexpecting his "Look, you put a few guys in jail, it doesn't mean the problem's been solved and everything's okay now" argument for why assigning a disproportionate amount of blame to him is unproductive, but he did manage to convince me that he's uniquely placed to be an ally to help fix the system; that he's someone who knows all of its intricacies and is sincere about achieving a sense of redemption by working on stopping other people from doing exactly what he did.


His argument for how his book tour isn't a cynical attempt to make money is convincing, too: to the small extent that he's able to make money from books and speaking, he's forced to use it to repay a $40m restitution order to the government and his victims.


The most surprising thing I learned was that the crimes he went to jail for were not the particularly objectionable democracy-perverting forms of corruption that we ascribe to him -- those are totally legal (even more so than before, thanks to Citizens United) and still happening today across Washington's 30,000 lobbyists -- but instead mostly unrelated charges, like mail fraud. He thinks that the only way to stop bribery in Congress is to ban political contributions from anyone who stands to benefit from public funds (which Lessig criticized as being far too ambiguous and broad: who doesn't stand to benefit from public funds?), and to ban lawmakers and their staff from later working for lobbyists for the rest of their lives. He described how, before his downfall, he would agree to hire a lawmaker's staffers later while they were still working for the lawmaker, and would then have control over them from that point onwards, even though no money had changed hands -- not only is this movement from being congressional staff to becoming a lobbyist still legal, it's daily routine.


I hope this talk series continues. I can't think of many other examples of powerful figures being brave enough to open themselves up and engage in an extended ethical (rather than legal or technical) critique and cross-examination by their peers and the public, and it was powerful to watch and learn from.

Charity, 2011 edition

Posted by Chris Ball Thu, 01 Dec 2011 15:57:00 GMT

Oops, only three blog posts in the last year. I've mostly been posting over at Google+, wherein I met a bunch of photographers and picked up a fledgling photography obsession of my own. I'll try to write a "what I did in the last year" blog post at some point.

This post isn't about that, though -- like last year, this year Madeleine and I are again donating N% of our joint pre-tax income to effective charities for each year that we've been married, and this year N is equal to 6. Mad has a post outlining why we're doing this and which groups she's chosen, and here's a writeup of who I decided to donate my half of the 6% to:

40% to Schistosomiasis Control Initiative

It's very common to think about international aid in terms of "lives saved", but it makes more sense to talk about something like "number of disability-adjusted life years increased" (DALYs). GiveWell thinks that this charity -- which concentrates on the "Neglected Tropical Diseases" which are usually worms/parasites -- offers an extremely effective intervention at improving DALYs; because these infections are readily treatable using very inexpensive drugs, yet often come with debilitating symptoms that don't quite kill the "host".

25% to Give Directly

Give Directly is a fascinating project. The charity simply finds the poorest people in an area (currently they're working in Kenya) and transfers money to them via mobile phone. This leaves the charity itself with very little overhead -- all the charity has to do is identify who the poorest people are, which they often do by looking at what kind of place they live in. The claim is that this outperforms many other attempts at aid; there's nowhere for the effect of the money to get diluted or misappropriated along the way.

I should be clear that I don't think this is the best possible aid intervention. But, as GiveWell points out, it should be the intervention that we treat as the baseline that other interventions are measured against -- if you think you have a better idea, then you should be able to prove it by comparing outcomes against this method. Give Directly has a commitment to measuring the quantitative effects of its work; I want to support finding out how well this intervention works, even though the optimist in me hopes we can do much better!

15% to GiveWell

GiveWell has dramatically changed how I think about and evaluate charitable giving. This year I've been pleased to see them doing things like exposing errors in commonly referenced DALY calculations, and generally acting as the quantitative sanity-checker for development charities.

15% to the Tor Project

Tor is a technology that helps its users achieve anonymous access to the Internet over a connection that may be being monitored; as a side-effect of this, it allows its users to get around filtering of their connections. I think this pairs up nicely with Madeleine's choice of donating to the Wikimedia Foundation -- it's important to have the world's knowledge available to everyone, not just the people who are lucky enough to have an unfiltered and unmonitored connection. I increased my donation to Tor this year after seeing how effective the Internet has been as a pro-democracy tool this year, and how many regimes tried to filter communication using it when it was being used by citizens to coordinate with each other.

5% to the EFF

While Tor works on "exporting" the Internet that we use to regimes that wish to block or filter it, the EFF is helping to keep the network itself safe from becoming controlled by groups like governments or media companies; attempting to preserve the freedoms that the net provides today.

Narrative Interfaces

Posted by Chris Ball Sat, 18 Jun 2011 04:05:00 GMT

As Scott's preview post explained, today was "Narrative Interfaces" day at OLPC — the general motivation for this work is that the current Sugar interface leaves you able to do lots of different activities with your XO laptop, but doesn't have any strong opinions about which you *should* do, or which order you should do them in. Wouldn't it be better if we could come up with a plot/narrative behind the activities that can be explored on an XO?

I've uploaded videos of the talks now. They are:
In the discussion afterwards we chatted about comics that do a good job of presenting non-fiction, as an alternative way of using narrative to present ideas — here's our reading list: If you'd prefer to download the videos directly, you can find the raw files here.

Thanks to everyone who participated! If you weren't able to attend in person but have comments after watching the videos, feel free to jump in with your thoughts on the Sugar Labs IAEP list.

EduJam 2011

Posted by Chris Ball Sat, 14 May 2011 18:39:00 GMT

I'm home from the EduJam conference in Montevideo, Uruguay — huge thanks to the organizers for a fun and productive event with around 80 Sugar and OLPC community members. We also got to spend some days before the conference visiting school deployments in Uruguay and asking about how they're using their XOs (Uruguay is the first country to have implemented One Laptop Per Child for each of its children!), what they enjoy, and what they're frustrated by.

I recorded video in the talks I attended, and collected video from people who recorded talks I didn't, and have started to upload them to the Dailymotion Sugarlabs account. Here's what I've got so far, and I'll keep adding to the list as I collect more:

Talks in both English and Spanish

Talks in English only

Talks in Spanish only

(Please let me know in the comments if there are problems with any of the videos. Thanks to Bert Freudenberg for help with encoding them.)

MIT Mystery Hunt 2011

Posted by Chris Ball Tue, 18 Jan 2011 19:01:00 GMT

Well, that was unexpected — the Mystery Hunt team I've hunted with for the past three years, Codex, won the hunt this year! It's the team's tenth year of competing and our first win. Congrats to everyone! Here's a Boston Globe article about the whole thing.

The hunt organizers did a beautiful job putting together the hunt (it took an estimated 20,000 person-hours), and the laser-etched "coin" we won the hunt by finding at 6am on Sunday morning was a reflection of how much effort had gone into the hunt in general:

The coin!
The coin!

Of course, this means that now it's our turn to write the hunt — as Scott says, our free time for the next year has just vanished. It'll be fun, though; it's always sad when the hunt ends and you realize you aren't going to get to hang out with the awesome people you just spent a sleepless weekend solving puzzles with until next year, but having to meet up regularly to write and test the puzzles for next year will fix that. We've got a very high bar to live up to, and a thirty-year-old tradition to keep alive.

(Oh, yeah, geekiest moment of the hunt: one of the puzzles — Redundant Obsolescence — involved plugging an Iomega Zip drive into my desktop PC via parallel port and reading files back off it, in Linux. I couldn't believe it worked.)

While I'm here and blogging, here's a guitar video I recorded over Christmas. I'm happy I finally got to record a Kaki King piece.

Giving Thanks

Posted by Chris Ball Fri, 26 Nov 2010 03:52:00 GMT

It's easy to find a multitude of things to be thankful for, and I like that the US has a holiday for reflecting on how lucky we've been. Today we've been hanging out with friends and cooking up a vegetarian/vegan feast, including a tofurducken:


Mad and I had our five-year wedding anniversary last month; last year we decided to donate N% of our joint gross yearly income to effective charities each year for our anniversary, where N is the number of years we've been married, so we're up to 5% this year. We decided to publish the list of charities we've chosen, both to show which charities we like donating to and to encourage others to consider doing something similar. My choices this year are:

Oxfam has an excellent reputation for fighting poverty in developing countries.

Givewell is a non-profit attempting to apply quantitative rigor to measuring how effective charities are, and VillageReach is in their #1 spot; they've proven themselves reliably able to save the lives of infants for under $1000 per child.

PSI works on global health, including HIV/AIDS, malaria and family planning.

The Fistula Foundation and ReSurge (formerly Interplast) treat health problems that we don't see much of ourselves because they're far more common in the developing world — a fistula operation, for example, is clearly life-transforming, and can be funded for $450.

The EFF and Tor Project fall under the banner of helping people to use technology to demand better government and uncensored access to information.

Git patches in Gnus

Posted by Chris Ball Mon, 04 Oct 2010 18:18:00 GMT

I took over maintaining the Linux kernel's MMC/SD/SDIO subsystem recently, and quickly found that I was spending too much time saving, applying and compile-testing submitted patches (and trying to remember which of these I'd done for a given patch). The following Emacs/Gnus function helps with that — with a single keypress when looking at a mail that contains a patch, it applies the patch to my git tree, runs the kernel's "checkpatch" tool to check for common errors, and kicks off a compile test in the background. I'm not much of an elisp coder, so feel free to critique it if you can.

(defun apply-mmc-patch ()
    "Take a gnus patch: apply; compile-test; checkpatch."
    (interactive)
    (setq default-directory "/home/cjb/git/mmc/")
    (setq compilation-directory "/home/cjb/git/mmc/")
    ; First, apply the patch.
    (dvc-gnus-article-apply-patch 2)
    ; Run 'git format-patch', and save the filename.
    (let ((patchfile (dvc-run-dvc-sync
        'xgit (delq nil (list "format-patch" "-k" "-1"))
        :finished 'dvc-output-buffer-handler)))
      ; Compile the result.
      (compile "make modules") 
      ; Now run checkpatch.
      (let ((exit-code (call-process "perl" nil nil nil
                     "scripts/checkpatch.pl"
                     patchfile)))
    (if (eq exit-code 0)
        (message "Checkpatch: OK")
      (message "Checkpatch: Failed")))))

KDB+KMS for nouveau/radeon

Posted by Chris Ball Thu, 19 Aug 2010 17:52:00 GMT

First, some background: KDB (a kernel debugger shell) and KMS (kernel mode-setting) combine to let you drop into a graphical shell when something debugger-worthy happens on your Linux machine. That thing might be a panic, or a breakpoint, or a hardware trap, or a manual entry into the kdb shell. Inside the shell you can, for example: get a backtrace, inspect dmesg or ps, look at memory contents, and kill tasks.

This is a big improvement over the previous model of "something bad happens to your laptop while it's in X, and the keyboard LEDs start blinking, and you hard-reboot and wonder what happened and wish your laptop had a serial port".

Here's a video of KDB+KMS in action — it's from Jason Wessel at Wind River, who deserves massive kudos for having enough patience to get all of this debugging code merged into mainline Linux to everyone's satisfaction:



Jesse recently wrote about how to give KDB+KMS a spin on Intel graphics chipsets, and now I've written patches that allow radeon and nouveau users to join in too. The method for testing them is similar to Jesse's:
  • git clone git://dev.laptop.org/users/cjb/linux-2.6
  • cd linux-2.6
  • git checkout kgdb-next
  • Config the kernel as in Jesse's post, and build/install it.
  • Boot with kgdboc=kms,kbd kernel arguments.
  • Enter KDB with sysrq-g, or echo g > /proc/sysrq-trigger, and type go to leave KDB.
If you test with radeon or nouveau, please let me know what hardware you tested on, and whether everything worked. Thanks!

An e-mail counting t-shirt

Posted by Chris Ball Tue, 30 Mar 2010 13:10:00 GMT

I've been wanting to get into electronics for a while now (it seems like a sensible thing for someone who works for a laptop manufacturer to do) but haven't known where to start. Back in January, the fine people at Sparkfun Electronics helped out with that by running a Free Day where they gave away electronics worth USD $100k: $100 free, to 1000 people. I was lucky to be one of the 1000 people, which put some electronics ideas within my reach that I otherwise would have found it hard to justify spending money on.

And, here's the result — Madeleine and I made a t-shirt together that displays how much unread e-mail I have using an Arduino Lilypad and Bluetooth dongle, and an Android phone to send the number of unread mails to the shirt. Here's an image of the center of the shirt, and a video showing it in action:

I've uploaded the source code that runs on the Lilypad and the python script that I'm running on the Android phone to my github account.

Computers that aren't computers

Posted by Chris Ball Sun, 07 Feb 2010 02:02:00 GMT

Me: "I think I'm done buying computers that I can't run my own code on."
Friend: "Just think of the iPad as being a pile of books. You can't run your code on those either."
Me: "Thinking of a computer as being a pile of books is like thinking of a guitar as being Abbey Road by the Beatles."

Btrfs snapshots proposal

Posted by Chris Ball Thu, 19 Nov 2009 18:40:00 GMT

I've written up a feature proposal on how we can use Btrfs snapshots to enable system rollbacks in Fedora 13, by gluing together the existing kernel code to do Btrfs snapshots, a UI for performing rollbacks, and a yum plugin to make snapshots automatically before each yum transaction. Lots of good comments so far, and LWN has written an article about it.

Heroes

Posted by Chris Ball Tue, 27 Oct 2009 17:28:00 GMT

Boston was good to me last week — I got to see two talks from two particularly inspiring and heroic people, a day apart. (And a Rodrigo y Gabriela gig on Friday, which perhaps wasn't as heroic, but was also awesome: check out Tamacun, Orion and Captain Casanova on Youtube.)

Now, on to the talks:

William Kamkwamba

When he was 14, William Kamkwamba built a working windmill at his house in Malawi, despite having dropped out of high school a few years earlier because his parents weren't able to afford to send him anymore. He knew what to build by looking at pictures of a windmill in a science textbook in a library, using a dictionary to translate the words that referred to the pictures from English to his native language of Chichewa, and believing that the presence of the photo meant that someone must have built one before, therefore it must be possible for him to do it too. He also had some experience with repairing radios, taking them apart and working out what each component was doing by trial and error. His story is so inspiring because he lacked enough schooling in English and Science to be expected to gain the knowledge of electromagnetics he picked up, lacked any money to buy parts to work with, but somehow achieved his goal anyway. He gave a humorous and fascinating talk at MIT last week with Bryan Mealer, the co-author of the book that tells his story: The Boy Who Harnessed The Wind.

Reading the book after the talk totally changed my understanding of what he'd done and why, though; the background for his wanting to build a windmill is not always mentioned in articles and interviews with him. The season before he started, there had been a famine throughout Malawi — there was a drought, and corrupt government officials had sold off the country's strategic grain reserves and kept the money, meaning that the government did nothing to help feed millions of subsistence farmers (including William's family) who were left with a small fraction of the amount of food they needed for that season. William's family lost a lot of weight, sold their possessions and dropped out of school to pay for food, and watched many of their friends and other villagers waste away and die from hunger over a period of months. The book contains detailed descriptions of what it's like to live and go to bed hungry, after maybe a few mouthfuls of food all day, that make me deeply ashamed that we allow this to happen to anyone in the world.

Given all this context, it becomes totally obvious what William was doing the next year at the library: the textbook said that windmills could be used to power water pumps, which would mean freedom for his village from having to go through another drought and famine. The surprising conclusion you're left with is: "Of course he built a windmill, teaching himself a massive amount of electronics that was described in a language he barely understood in order to do so — what else was he supposed to do?".

Peter Singer

The second talk was from Peter Singer, who's an applied ethicist at Princeton, and writes about modern ethical questions from a utilitarian perspective. He wrote Animal Liberation thirty years ago, which is thought of as having founded the animal rights movement; his work persuaded me to start approaching vegetarianism, then become vegetarian nearly three years ago, and mostly-vegan earlier this year (vegan at home, vegetarian when eating out with friends or if it's difficult to find vegan food). Lately he's been writing about poverty and the nature of our responsibility to people suffering due to poverty in countries other than our own, and has a powerful argument that we aren't doing nearly enough. I first encountered his anti-poverty work with What Should a Billionaire Give — and What Should You? in the New York Times, and he's since written a book on the subject, The Life You Can Save. The book is excellent — as well as describing the moral basis for aid, he handles common objections to charitable giving, including what responsibility we have when others aren't accepting their share of it, where it's okay for us to stop and feel like we've done enough, why we shouldn't be giving money locally instead, and how we can find efficient and life-changing charities to donate to. Here's the book's opening and most provocative question, first proposed in his 1972 paper Famine, Affluence, and Morality:

"On your way to work, you pass a small pond. On hot days, children sometimes play in the pond, which is only about knee-deep. The weather's cool today, though, and the hour is early, so you are surprised to see a child splashing about in the pond. As you get closer, you see that it is a very young child, just a toddler, who is flailing about, unable to stay upright or walk out of the pond. You look for the parents or babysitter, but there is no one else around. The child is unable to keep his head above the water for more than a few seconds at a time. If you don't wade in and pull him out, he seems likely to drown. Wading in is easy and safe, but you will ruin the new shoes you bought only a few days ago, and get your suit wet and muddy. By the time you hand the child over to someone responsible for him, and change your clothes, you'll be late for work. What should you do?"

Of course, we all answer that the minor inconvenience of having to buy a new pair of shoes and change our clothes are not valid excuses for refusing to save a life, and the follow-up hits you like a ton of bricks: there actually are people dying from poverty every day, around 30,000 of them, and we really can save a life for not much more than the cost of a good pair of shoes. Furthermore, more than two and a half billion people live on the equivalent of less than USD $2 per day. How, then, can we say that we're different from the person who walks by the lake, sees the child drowning, realizes they could save them, and does nothing?

Singer's book explores the differences between the two situations — primarily that in one a child is next to you while in another they are far away — and concludes that this cannot be a sufficiently different situation to present a different moral answer, if we claim to hold ethical beliefs like "the value of a human life is the same no matter where in the world it is" and "a human life is worth more than a pair of shoes".

Now, I didn't mean for this post to make you feel guilty — in fact, I'm feeling very optimistic about this issue. Singer observes at the beginning of the book that the struggle to reduce suffering due to poverty has historically been a sort of climb towards an unreachable, unknowably distant mountain peak; but now we have cleared the clouds and can see the summit, our ability to do this is clearly within our means. I want other people to enjoy life the way I did at the gig on Friday night. While I can't give everyone tickets to go to concerts, I can certainly work towards them having enough food so that the William Kamkwambas of the world can, rather than trying to fall asleep in darkness and hunger, enjoy a full stomach and some good music with a radio they've managed to repair.

On keynotes and apologies

Posted by Chris Ball Fri, 25 Sep 2009 21:35:00 GMT

I wasn't going to blog about this, but I'm becoming pretty angry about it now, and I think I might actually have something constructive to say.

Here's the story: Mark Shuttleworth gave a keynote at LinuxCon, which I attended, in which he said lots of reasonable things and one very unfortunate thing. Paraphrased, he said that if we did a better job at considering our non-technical users and accepting help from expert UI designers, we'd have an easier time "explaining to girls what we actually do". (By girls, he meant women, not female children.) I'd like to be able to provide a direct transcript when critiquing his words, but the LinuxCon organizers don't seem to be willing to make the video available for free, so I can't do that yet. I'll link to it as soon as it's available.

Before I get started properly, I want to make it clear that I like and respect Mark Shuttleworth. I regularly use and recommend Ubuntu to other people, and am very glad that he's doing what he's doing in the world. There's no personal animosity or ill will behind this post at all.

It's actually not just the Ubuntu distribution that I recommend: I'm also hugely impressed by the Ubuntu Code of Conduct, which was a groundbreaking document at the time it was adopted, and made it clear — for the first time — that there is a free software community that is willing to put a stake in the ground and say that it's not a place for people who want to communicate by disrespecting someone else, or another group. I think the Ubuntu community is one of the most tolerant, welcoming and diverse free software communities we have, and I'm sure that this is a reflection of Mark's own thoughts on the matter.

So, back to the keynote. Kirrily Robert heard about this statement of Mark's from Emma Jane Hogbin's transcript in a conversation on identi.ca, and wrote an e-mail and blog post asking Mark to apologize and clear this up. Sam Varghese now has a blog post attacking Kirrily Robert, because Kirrily based her objection on someone else's transcript of what was said rather than being there herself.

Well, I was at the keynote too, and was paying attention, and it turns out that even with context applied, someone who talks about "explaining to girls what we actually do" when talking about free software really is saying something sexist, and buying into the noxious stereotype that women can't be developers or tech-savvy; that they'll never be a real part of our group, even if a few of them are brave enough to try in the face of other people dismissing their efforts (and Mark certainly isn't the first to have done that).

This statement actually wasn't the first exclusionary thing Mark had said in the talk, in my opinion. Earlier he attempted another joke about how when he talks about "releases", he doesn't mean "release" as in "happy ending". The joke didn't go over very well, and he made a comment about how it must be because we were tired and not listening properly. Actually, I was confused because I already felt pretty sure that he was talking about software, rather than male orgasms and hookers, because that's supposed to be a safe assumption to make during a technical conference keynote.

So, Sam Varghese can stop claiming that Mark's statement wasn't sexist because no-one in the room found it sexist: there's no doubt in my mind that it was a sexist thing to say, and I was there.

Varghese tries to paint himself as a martyr, saying that he's "sure he'll be shouted down too" for denying sexism, but it's actually extremely, overwhelmingly common to attack the person who points out sexism in free software communities — common enough that Matt Zimmerman, Canonical's CTO, has an excellent blog post on the subject: Backlash: feminism considered harmful. The backlash is so strong that if Kirrily were just an occasional contributor, I'd be thoroughly unsurprised if the kind of attacks she's receiving drove her away from free software completely. She's been in the community for long enough, though, that she's willing to put effort into calling out sexism even though she'll be attacked and ridiculed for it by people who think that there's nothing wrong with the situation. Thanks for not giving up in disgust and leaving us alone to enjoy our 1% participation by women, Kirrily.

Varghese finishes his post with:

"Shuttleworth has many faults, I'm sure, but one has to always assume that a person is innocent until proven guilty. If someone violates that basic rule, which should extend to every human on the planet, then that person is in the wrong."

Look, we're not talking about a trial that attempts to judge whether Mark is a good or bad person; we need to move past the idea that someone who said something sexist is "guilty" or deserving of punishment. Kirrily's letter, after all, didn't ask Mark to apologize for being a sexist person (which I don't think that anyone involved actually thinks is true), it just asked for an apology for one sexist thing he said. I don't know anyone who doesn't behave in sexist ways sometimes, because it turns out that discarding privilege is really goddamn hard, even when you're consciously trying to. We need to make it clear that someone who accidentally said something sexist is not "a sexist", or a bad person, or worthy of our contempt, or deserving of a ruling of innocence or guilt. I do respect Mark, and I still think he said something sexist, and if he apologizes for accidentally saying something sexist and says he'll try to make amends, that makes everything totally okay with me. We need to be able to admit when we say/do something sexist without it turning into something huge and unmanagable, because it's something that's probably going to happen quite a lot.

Matthew Jones also made a post defending Mark and I'd like to reply to that too:

"When Mark said try to explain to girls, he was not talking about women not understanding technology. He was talking about how hard the design work is to do, and that if things were designed poorly or had low usability, he would not know how to explain them to girls (my translation). The tone of his voice suggested sarcastic embarrassment, which implies he would prefer to impress girls."

I totally agree with the context of Mark's statement provided, although I don't at all see how that's "not talking about women not understanding technology". The statement is still as exclusionary a statement given this context — the fact that Mark may like to impress women doesn't excuse that his statement thinks of women as a synonym for "people who don't understand how software works"! That's a really destructive phrasing that we should all reject. It's not hard to substitute "the average person" or just "people who aren't as interested in computers as we are" and turn the statement from exclusionary-to-women to gender-neutral.

Here are some of the arguments made against asking Mark for an apology in the comments on Kirrily's blog post:

Mark is a nice guy. I agree! However, when someone (metaphorically, perhaps) steps on someone else's feet accidentally, you expect them to say "Oops, sorry." regardless of how nice a person they are; that's just not relevant to the fact that someone else is hurt and it's their fault. If they refused to apologize for it, that might change your idea of how nice a person they are, but the fact that they hurt someone unintentionally doesn't have any bearing on whether they're a good or bad person in the past or in the future. It's just a thing they did that they should apologize for.

Mark wasn't trying to offend people, he was just making a joke. I agree with this too, but making a joke doesn't stop the words we choose to tell the joke with from having power.

And, perhaps one that I'm expecting to see in the comments on this post:

Hey, you're not a woman, so you can't be upset about this. I think that actually helps, in this case. Sam Varghese used a lot of very loaded words like "emotional" and "irrational" in his rejection of Kirrily's post that I think were an idea of his that she shouldn't be able to complain about this because she's a woman. I don't agree with that restriction, of course, but I'm happy to help remove it from the discussion.

Finally, I want to repeat that for me the real shame here isn't that Mark said something unfortunate — we can all say something unfortunate when we're speaking in front of a large crowd for a long time, myself certainly included. What's a shame is that it doesn't take a superhuman dose of empathy to give a short and sincere apology for an obviously harmful joke afterwards, yet we don't have one yet. To make matters worse, it's the second time in a few months that someone's implied that women are people who lack technical knowledge during a conference keynote, and it seems to be the second time we aren't getting any kind of apology for it. We're left to conclude that the biggest heroes in free software — the people who speak for and about us to the world — don't care much about whether women feel invited to or excluded from free software, or how they could use their power to affect that.

The Best Card Trick

Posted by Chris Ball Thu, 17 Sep 2009 06:21:00 GMT

I gave a talk on The Best Card Trick at the Boston Haskell meetup tonight, and then we implemented the technique together in Haskell as a group. Afterwards, we compared our program with this one that my friend Mark Carroll wrote a long time ago. Here's a summary of the trick from the paper's abstract:

You, my friend, are about to witness the best card trick there is. Here, take this ordinary deck of cards, and draw a hand of five cards from it. Choose them deliberately or randomly, whichever you prefer — but do not show them to me! Show them instead to my lovely assistant, who will now give me four of them, one at a time: the 7♠, then the Q♥, the 8♣, the 3♦. There is one card left in your hand, known only to you and my assistant. And the hidden card, my friend, is the K♠.

In even-more-mind-blowing news, today John McCain gave a talk about OLPC.

Mad and I just got back from a fun two-week vacation — the first week was spent in Mexico City, visiting Mika and Mako and meeting Gunnar and Carolina for the first time, and the second week in Peru with Mad's family: Ayacucho, Cusco, Machu Picchu and Lima.

We spent a while working out a long list of stuff to do in Mexico City; here's the list of what we did, together with Mad's photos, in case you're interested in having a fun vacation in Mexico City too.

Teaching old code new tricks

Posted by Chris Ball Mon, 06 Jul 2009 22:58:00 GMT

ExploreTree

Over the July 4th weekend, I found time to release the tree visualizer that Mad and I wrote for the Processing Time code jam a few months ago. Mad's worked on it some more since the code jam, adding a search function, options for specifying font size and the tree depth shown, and a link from each node to its Wikipedia page. The program's available as an applet now, at:

http://exploretree.org/

Feedback welcome, especially if it doesn't work for you and you're able to figure out why.

Bugs Everywhere

Bugs Everywhere, everyone's favourite distributed bugtracker, has been seeing a decent amount of work lately thanks to some strong efforts:

It's nice to keep momentum going on some small projects. Counter-intuitively, I think it's much easier not to get tired of programming when you're working on code for work and different code outside of work, than when you're just concentrating on the code for work.

Microfinance in Ayacucho

Posted by Chris Ball Sat, 27 Jun 2009 04:17:00 GMT

My awesome sister-in-law Suzy is in Ayacucho, Peru, volunteering for Kiva for around nine months. One of the difficulties with poverty relief charities is that people feel a disconnect between their donation and the result, and Kiva works around this problem by personalizing the process of making a loan to a specific entrepreneur. Kiva also empowers recipients by organizing loans that the recipients are expected to pay back.

Suzy's working with a local microfinance organization, interviewing potential borrowers and uploading their profiles to the main Kiva site for lenders to see. She's posted three times to the main Kiva Fellows blog now, and I hereby humbly present her posts. You should read them.

XO-1.5 bringup

Posted by Chris Ball Sat, 06 Jun 2009 14:12:00 GMT

Back from Taipei, and appropriately jetlagged, after a successful bringup of the XO-1.5. The bringup team did some interviews for olpc.tv while we were there, including a demo with Fedora 11 running on the new board. There are interviews with John Watlington (hardware), Richard Smith and Mitch Bradley (hardware/firmware), and me (software), which I've embedded below.

Thanks to Charbax for recording the interviews! Was also wonderful to see the new Pixel Qi screen — I'm looking forward to seeing it on mainstream laptops in the coming months.

Jorge Cardoso - Milonga

Posted by Chris Ball Tue, 19 May 2009 03:47:00 GMT

I'm off to Taipei to help with the XO-1.5 bringup. Before I go, here's a new guitar piece — the milonga is a Uruguayan relative of the tango.
