Just finished the stack machine, very nice work. Love the presentation and the code is beautiful. Looking forward to future snacks!

Sounds like you may enjoy My Rails Blob: http://railsblob.blogspot.ca/2006/08/my-new-blob.html

See https://github.com/snaptoken/kilo-tutorial/issues/4
You may have a broken version of the font locally. If you download the offline version of the tutorial, it'll come with all the fonts it uses and hopefully will work.

It seems to be doing fine now, but you can always download a local copy (it's all static HTML) from https://github.com/snaptoken/kilo-tutorial/releases

Well, you could distribute your encrypted wallet as widely as you want, without worrying about theft or loss (if you have a good passphrase and spread the wallet to enough locations), before you start receiving bitcoins to it.
The point of using the Pi is that you can make sure the decrypted wallet data only ever exists for a short time in RAM on hardware that is very likely non-malicious and that never has and never will connect to the Internet. If I had a significant amount of bitcoins sitting in an address that was generated by my laptop that I've been using regularly for the last four years, then I wouldn't sleep at night.

Aw, I was hoping to see that slave mode was fixed. I want to use slave mode to make a music player with my own user interface and library/playlist manager in Ruby without having to worry about how to actually play the music. Unfortunately slave mode in mplayer seems kind of unstable and sometimes even gives the wrong answer (I think it's a known bug). I wasn't aware of mplayer2, I'll have to try that and see if it works any better.
But does anyone know of a program or library with a proper interface for controlling a music player?

I don't know if this works for everyone, (and I hate to appeal to magic), but I'm pretty sure it was http://mislav.uniqpath.com/poignant-guide/book/chapter-3.htm... that gave me a visceral understanding of Ruby's syntax. For example, the slashes surrounding the Regexp are like pins that you stick the Regexp onto the paper with, and it lights up if the pattern matches. The at signs stand for "ATtribute". Exclamation/question marks have meanings analogous to their natural language counterparts. And the vertical bars form a little chute that the block variables slide down into the block through. It's really fun.

Jan. 2013 was _why's first reappearance. He had actually updated his website with the first couple entries in the print queue in December, but no one noticed until January. After people noticed ( http://news.ycombinator.com/item?id=5015087 ), _why started updating it with more pages in the print queue, one of which said the print queue was going down until April 18, and would then be up during the hours of 4 to 12. Which sounded like _why was going to do something big that day.

thdvl also changed the SPOOL/SOLICIT file to a bunch of base64, which decodes to a gif image, which is of a QR code that points to the URL http://en.wikipedia.org/wiki/Epistulae_morales_ad_Lucilium

If anyone wants to hook their actual printer up to _why's queue (which I'm pretty sure is what he intended), iandennismiller transcribed the OCaml program in SPOOL/HOMEWORK which polls whytheluckystiff.net and sends the PCL files to your printer: https://github.com/cwales/cwales.github.com/pull/4
It's quite magical. I was woken up this morning by my printer, when the first pages were being published. Now every 5, 10, or 15 minutes my printer starts clanking away (it's an old one) and a brand new page slowly emerges. Great way to read a novel, if that's what it is.

It's a little taller, but it still looks like an o to me. If you go to http://www.youtube.com/watch?v=ShpcjWG_Meo it says "This video is unavailable", which means that a video did exist at some point at that URL.

Heh, not knowing Java very well, I scoured the BigInteger docs for quirks and loopholes, then gave up and found your comment. I guess "java.security.SecureRandom" sounded too impregnably secure to be worth looking into.
For https://viewsourcecode.org/snaptoken/kilo/02.enteringRawMode... , the code is kept in a git repo where each commit is a step in the tutorial. This way steps can be modified, reordered, or split into more steps using git interactive rebase (git rebase -i).
I'm working on a tool which abstracts away git rebase, and gives you a nicer interface for manipulating the series of steps in your tutorial. For example, you can run `leg 3` to checkout step 3, make edits to it, and then run `leg amend` to apply the changes, resolving conflicts as the changes make their way through the rest of the tutorial's steps.
The tool is still in very early development, but here's a quick tutorial to get a better idea of how it works: https://github.com/snaptoken/leg/blob/master/TUTORIAL.md
Also, I'm playing around with a "literate diff" file format that might be of interest: https://github.com/snaptoken/tgc-tutorial/blob/master/doc/02...
