I will forward any bitcoins sent to the address 149eBtWS6i8cwQdPQJJ8hAGpDuEqNidyTj to whoever makes this. If it doesn't happen in 1 year, any donations will be forwarded to the EFF instead.
Woken at 3 am by fil singing "Join Us Now And Share The Software" (all verses!) I could not get back to sleep and spent 3 hours thinking up a new take on the hopelessly blocked dpkg-source v3 (git) format.
A diagram of the new plan, which should meet all ftpmaster requirements, is posted in Hacklab 1. I am looking for reviewers.
Fil has paid me back in full for his drunken carousing by gifting me a Rhombus-Tech system on a chip on a PCMCIA card. I've checked this new computer, which features a modern multicore ARM CPU, into my wallet.
And that's 10% of what went on today at DebConf for me, and we've not even gotten to the cheese and wine party tonight.
DIY crowdfunding and bitcoin
Well, my git-annex crowdfunding campaign is half way to its August 15th conclusion. So far it's raised more than five times what I hoped it would. I wish I could say I'm like some canny NASA engineer who intentionally sets low expectations for their Mars rover, but in both the previous kickstarter and this campaign I've really had no idea how far it'd go. I'm glad that I'll be working on git-annex for another year.
I was particularly unsure if it'd be successful to move off Kickstarter. During the git-annex assistant Kickstarter campaign, I saw many small contributions from people who learned of it due to it being a successfully funded project, a staff pick, etc. Losing that easy network effect is a gamble.
So far I've had only half the number of contributors that I got on Kickstarter. I've basically missed out entirely on the $5 level casual contributors. On the other hand, my backers have generally been more generous (and some have been exceedingly generous). And I've avoided rewards that will cost much money, so I may end up in the same ballpark funding level in the end!
I also was curious to experiment with Bitcoin in this campaign. Partly because Paypal isn't available everywhere internationally, and takes really obnoxious percentages of transactions (though probably not as bad as Kickstarter taking its percentage followed by Amazon payments taking its percentage..) and partly because there seem to be interesting possibilities for supporting free software with Bitcoin. (Especially if any of the microtransactions on top of Bitcoin take off.)
So far 5% of backers have used Bitcoin. It's been quite strange to actually have significant amounts of bitcoins in my wallet. Wordpress has had 94 bitcoin payments over 9 months since starting accepting them. I've had 47 payments in the two weeks my campaign has run so far. Wow!
Most of the bitcoin payments have come in via Coinbase (a few people have found my direct payment address), but of those very few were using bitcoin purchased on Coinbase. Most are probably transfers of bitcoin they already had, or perhaps bitcoin purchased on other sites.
The one technical issue I've had with using bitcoin is that Coinbase has not provided details about who sent most of the donations. Probably some of them are intentionally anonymous, but I suspect Coinbase's interface to claim incoming bitcoin transactions failed for some of them. (If you donated bitcoin and want to actually get a reward, please email me.)
By the way, I'm converting most of the bitcoins back to USD pretty quickly. I'm not interested in speculating on currency exchange rates with money that has been donated so I can accomplish a particular task..
I put up the campaign website without any means in place to handle updating it. This is because I never automate anything until I've done it at least 10 times by hand. ;) After the first trickle of donations became a flood, I quickly realized I needed at least something to handle keeping the numbers straight.
What I whipped up in an hour of coding is a system where I enter incoming payments into a hledger file and a small haskell program parses that and writes out various files that are included into the website. Amusingly the percentage calculation and display code was copied from git-annex, so part of git-annex is helping run its own fundraising campaign. The campaign video is itself hosted in a public git-annex repository, come to think of it.
The rest of the site is built using ikiwiki. Given that it's hosted at Branchable, this is a high level of dogfooding and DIY. There are certianly better crowdfunding platforms, but all I miss in this one is automated transaction entry. And I have total flexability, double entry accounting, and a powerful static website generator that handled being on the top of Hacker News without a sweat. Oh, and some money. What's not to like?
git-annex as a podcatcher
As a Sunday diversion, I wrote 150 lines of code and turned git-annex into a podcatcher!
I've been using hpodder, a podcatcher written in Haskell. But John Goerzen hasn't had time to maintain it, and it fell out of Debian a while ago. John suggested I maintain it, but I have not found the time, and it'd be another mass of code for me to learn and worry about.
Also, hpodder has some misfeatures common to the "podcatcher" genre:
git annex addurlto register the url where a file came from, so when I check files in with git-annex after the fact they're missing that useful metadata and I can't just
git annex getthem to re-download them from the podcast.
So, here's a rethink of the podcatcher genre:
cd annex; git annex importfeed http://url/to/podcast http://another/podcast
There is no database of feeds at all. Although of course you can check a list of them right into the same git repository, next to the files it adds. git-annex already keeps track of urls associated with content, so it reuses that to know which urls it's already downloaded. So when you're done with a podcast file and delete it, it won't download it again.
This is a podcatcher that doesn't need to actually download podcast files!
--fast, it only records the existence of files in git,
git annex get will download them from the web (or perhaps from
a nearer location that git-annex knows about).
Took just 3 hours to write, and that's including full control over
the filenames it uses (
and automatic resuming of interrupted downloads. Most of what I needed
was already available in git-annex's utility libraries or Hackage.
Technically, the only part of this that was hard at all was efficiently querying the git repository for a list of all known urls. I found a pretty fast way to do it, but might add a local cache file later on.
guesting on GitMinutes
Last Friday, I spent and hour and a half clamping a landline phone to the side of my head, while also wearing a headset. I was recording an interview on the GitMinutes podcast about git-annex.
I've been listening to GitMinutes for a while, ever since I heard git-annex
was mentioned on it. Actually, I think it's come up in 4 or 5 interviews on
the podcast. Most notably with core git dev Peff King, who had some
interesting things to say, for sure. I responded to that in my
interview, and we covered quite a wide amount of stuff in reasonable depth
in just over an hour. Thomas is quite a good host and great at drawing
stuff out, and it's nice to not need to worry about going into too much
technical depth. (Although I didn't get a chance to explain the automatic
union merging used to maintain the
This is the first podcast I've been in, and I've always worried about audio quality if I was in one. That is, I'd want it to be really good, and probably end up annoying the host. ;) For this one, we settled on using my land line call, which went through some Skype thing to get the Europe, and mixing in a local recording I made with a not too great headset. I think the result is pretty good, considering.
You can listen to the whole thing here, if you dare! (1 hour 8 minutes) http://episodes.gitminutes.com/2013/07/gitminutes-16-joey-hess-on-git-annex.html

git-annex fundraising campaign update: Initial goal reached in a mere seven hours. I will be developing git-annex fulltime for at least the next three months! Gone to stretch goal.
Also it made the top of Hacker News: thread
New git-annex crowdfunding campaign
Having reached the end of my Kickstarter funded year working on the git-annex assistant, I've decided to try one more crowdfunding campaign, to see if I can get funded to work on it a little while longer. I went back and forth on this for a while. The Kickstarter funded development was extremely successful (one of the most productive years of my life). I certianly want to work on git-annex more, and have lots more stuff to do, particularly around security and encryption. On the other hand, it's hard to frame ongoing development as a normal Kickstarter campaign to start something new.
Anyway, I've decided to go ahead and try it, and not do it through Kickstarter this time. So I have my own website set up and accepting donations, and hopefully I'll make enough to spend a few more months working on git-annex.
... And if not, I'll probably spend a few months working on git-annex part time, while looking for paying work with the rest of my time.
By the way, I'm taking payments in both US Dollars (via Paypal) and Bitcoin (via Coinbase). Can't wait to see how this works out!
New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
