amatus··on Clojure build tool Boot 2.0 RC1 out now
Does it build hoplon yet?
amatus··on The true power of regular expressions
This should be titled "The true power of PCREs"
amatus··on AMD Will Build 64-bit ARM based Opteron CPUs for Servers, Production in 2014
> Nobody has ever tried to design a sub 1 watt x86 design.

Transmeta tried and succeeded.

amatus··on Cute riddle: Four kids holding one toy balloon
I believe it is exactly the picture-hanging puzzle, upside-down.
amatus··on NASA Pursues Atom Optics to Detect Gravitational Waves
Yes. As I understand it rubidium is used because you can cool it with cheap laser diodes from CD players.
amatus··on (l)uriel has passed away
I loved arguing with him and watching major argue with him in #vsta and #fmios. Unfortunately I can't find the IRC logs anymore.
amatus··on Xkcd's world - pieced together with AngularJS (warning: big images)
A friend tells me there's a Limbo reference in there but I don't know what it is.
amatus··on Hacker holds alleged Romney tax returns ransom for $1M in Bitcoins
It is not trivial to check the bitcoin block chain to verify that enough money was transferred into the publicly-known release-now account?
amatus··on Coding Horror: I Was a Teenage Hacker
http://store.2600.com/summer2001.html - Fun with Fortress
amatus··on Coding Horror: I Was a Teenage Hacker
I did something similar in high school using the PC speakers of Win95 machines. The music was controlled from one machine that would send out broadcast UDP messages.
amatus··on Coding Horror: I Was a Teenage Hacker
In high school I taught myself x86 assembly and reverse engineered fortres.exe, published the results in 2600. Good times.
amatus··on A global decentralized encrypted datastore with anonymous publishing
One could simply modify the known file in any way (say, appending garbage) to change the decryption key, ciphertext, and storage key.
amatus··on Git script to measure contributor LOCs
For those of us not on BSD:

    git ls-files -z | xargs -0 -n1 -E'\n' git blame --date short -wCMcp | perl -pe 's/^.*?\((.*?) +\d{4}-\d{2}-\d{2} +\d+\).*/\1/' | sort | uniq -c | sort -rn
amatus··on Lisp as the Maxwell’s equations of software
The story you read about Feynman is this one: http://longnow.org/essays/richard-feynman-connection-machine...

I remember seeing a program that would output Haskell functions given just their type signatures. If you think of type signatures as invariants, this is exactly what drostie described. Alas my Google-fu was unable to find a reference to it.

amatus··on Building data structures that are smaller than an array and faster (in C)
Looks like you still have some bugs:

  rewritten data: 1 0 2 3 0 3
  first row     : 0 0 1 1 0 1
  group a       : 1 0     1
  group b       :     2 2   3
Group a and group b don't seem to match up with the data. Or I've misunderstood something.
amatus··on A Senseless Conversation
Really? You were completely OK with the telepathic brain-computer interface and went off the rails when the sensory deprivation was too good?
amatus··on The US recording industry is stealing from me
I'd be interested to know what the YouTube ToS says about this. It's likely that they can take away your ad revenue for no reason at all. Instead of complaining that someone stole your ad revenue, you should be thanking the all mighty Google every time they are gracious enough to give you a single cent of their ad revenue.
amatus··on Anonymous plans to take down the 13 root DNS servers that power the Internet?
So it's not just me. Thanks.
amatus··on Anonymous plans to take down the 13 root DNS servers that power the Internet?
Is it just me or does it seem like this attack will be self-defeating? They are relying on DNS servers to serve responses in order to make DNS servers stop serving responses.
amatus··on How the Boehm Garbage Collector Works
This would fail badly on a http://en.wikipedia.org/wiki/XOR_linked_list
amatus··on LibreOffice to go Android and HTML5
I'm seriously considering this as an alternative to Google Docs.
amatus··on Nude.js: Nudity Detection with JavaScript
Very much so.
amatus··on Idris - pure functional programming language with dependent types
Am I correct in my understanding of these types?

  Vect a n = vector of a with known length n
  (n ** Vect a n) = vector of a with unknown length n
When I think of it this way it's obvious why filter takes a Vect and returns a pair. Though it seems ugly to have to write each vector function to take both "static" and "dynamic" vectors.
amatus··on Mathematicians Solve Minimum Sudoku Problem
They did produce a formal solution/proof. The disappointing part is that it contains billions of statements that don't give us any insight about the problem.
amatus··on Universal transistor serves as a basis to perform any logic function
tl;dr: This transistor doesn't use doped silicon, instead it has an extra gate which gives the effect of dynamically choosing the polarity.
amatus··on The Day I Saw Van Gogh’s Genius in a New Light
This is moot for another reason. Your eyes take in the full spectrum of color and produce 3 scalar values for red, green, and blue. One can take a work of art, illuminate it with pure white light (containing all colors, not just red, green, and blue), determine these RGB values that your eyes will experience, and store them in an image file. You can takes this file and reproduce the work on a computer monitor, on a printer, etc. It will look the same as the work of art under white light. As soon as you illuminate the work of art with different light, all bets are off. The RGB values do not contain enough information to determine what the work of art would look like under arbitrary spectrum. For extreme examples consider the following effects: http://en.wikipedia.org/wiki/Fluorescence http://en.wikipedia.org/wiki/Phosphorescence http://en.wikipedia.org/wiki/Iridescence

Conclusion: illuminating a reproduction under different light, or processing a reproduction (an image file) in a computer, will not necessarily give you an accurate representation of what the original would look like. We need more information to know if what they saw in that light room is actually what the original would look like under that light. The same goes for the examples on the page.

amatus··on [dead]
I started with telling Spock "xyzzy" and they quickly all started wishing each other "Merry Christmas". I only let the loop continue until I could stop laughing.
amatus··on Anybody else think we need a HN meetup in Austin?
I'm in.
amatus··on Why Is The Defense Department Snooping On My Phone?
Looks like this was the case.

> Aha! The IP is assigned to my phone’s GSM interface, so it looks like it’s benign after all. > That did the tip, Amatus!
