| 14:14 | < ReivSLEP> | ...cat concantenates? I thought it just read the file. >.> |
| 14:15 | | * ReivSLEP uses 'cat filename' on a semi-regular basis to read small filenames without futzing about with pico, etc |
| 14:18 | <@ToxicFrog> | Also a common use. |
| 14:18 | <@ToxicFrog> | However, 'cat a b c d e f > abcdef' is how you generally concatenate stuff. |
| 14:21 | <@ToxicFrog> | AnnoDomini: several. Cygwin (www.cygwin.com) and Mingw (www.mingw.org) both come with one. If you'd like something you can pick and choose from, gnuwin32 (gnuwin32.sourceforge.net) and unxutils (unxutils.sourceforge.net) both have it, too. |

| 14:22 | < ReivSLEP> | Aha, so long as I wasn't going to accidentally break anything. >.> |
| 14:22 | <@ToxicFrog> | Note that of these, Cygwin you probably don't want unless you're planning to use more than just cat and don't intend to package and distribute whatever it is you're working on. |
| 14:23 | <@ToxicFrog> | If you do, or if you only need cat, go with gnuwin32 or unxutils. |
| 14:24 | <@AnnoDomini> | Thanks. I'll look into it. |
| 14:34 | | * AnnoDomini fails to understand how to use the thing. |
| 14:41 | < MyCatSchemes> | ReivSLEP: cat file1.raw file2.raw > /dev/dsp, etc. |
| 14:41 | < MyCatSchemes> | ReivSLEP: though generally I uses a FIFO with a copy of "mplayer -rawaudio on" hanging off the back of it, instead. |
| 14:42 | <@AnnoDomini> | Anyone know how to use the unxutils version? |
| 14:43 | | * AnnoDomini is having no luck. |
| 14:44 | <@gnolam> | AnnoDomini: what are you trying to do? |
| 14:44 | <@AnnoDomini> | Concatenate files a, b and c into d. |
| 14:45 | <@gnolam> | Under windows? |
| 14:45 | <@AnnoDomini> | Yes. |
| 14:46 | <@gnolam> | copy /b foo.bar+frotz.bar fnord.bar |
| 14:49 | <@AnnoDomini> | Wow. Thanks, that worked. |
| 14:49 | <@AnnoDomini> | What's the /b do, out of curiosity? |
| 14:50 | <@AnnoDomini> | Without it, I seem to get the SUB code at the end. |
| 14:50 | <@gnolam> | Specifies binary files. |
| 14:50 | <@AnnoDomini> | How many files can it do? |
| 14:51 | <@gnolam> | Dunno. Lots? :) |
| 14:52 | <@gnolam> | But if there's a limit, there's nothing preventing you from doing successive concatenation. |
| 14:53 | | * gnolam flees the scene again. |
| 14:55 | <@AnnoDomini> | I suppose not. It's trivial to make a batch file. |

| 18:17 | <@ToxicFrog> | *says. |
| 18:19 | <@Lerhir> | Didn't work for me. I copied cat.exe to the folder, made a shortcut to it, and specified '"<path>\cat.exe" file1 file2 > file3' for its run path. |
| 18:20 | <@Lerhir> | It just displayed text (too quick for me to follow). |
| 18:20 | <@Lerhir> | And the exited. |
| 18:21 | <@ToxicFrog> | Did you try actually runnin git from the command line to see what the text was? |
| 18:21 | <@Lerhir> | It was the text I wanted (well, the first file anyway) when I took a screenshot. |
| 18:23 | <@ToxicFrog> | Oh. I see the problem |
| 18:23 | <@ToxicFrog> | '>' isn't part of the cat command, it's a shell redirect. |
| 18:23 | <@ToxicFrog> | Works in batch files and from the command line. |
| 18:24 | <@ToxicFrog> | Does not work in shortcuts. |
| 18:24 | <@Lerhir> | Huh. |
| 18:24 | <@Lerhir> | Well, in any case, DOS' copy works. |

| 21:12 | < jerith> | Find the value of d < 1000 for which 1/d contains the longest recurring cycle. |
| 21:13 | < Vornicus> | ...not actually that hard. I assume you're working in base 10? |
| 21:13 | <@ToxicFrog> | ...in what radix? |
| 21:14 | < jerith> | Base 10. |
| 21:15 | < Vornicus> | See, there's a cool trick - the length of the cycle for a number d is the same as the smallest number n such that d | 10**n - 1 |
| 21:15 | < jerith> | I have a couple of ideas, but none are clean. |
| 21:16 | < Vornicus> | :) |
| 21:16 | < jerith> | What is | in this context? |
| 21:18 | < Vornicus> | a | b -> b is evenly divisible by a |
| 21:18 | < Vornicus> | oh, actually, I tell a lie - you first have to divide d by 2 and 5 until you can't any more. |
| 21:31 | | * Vornicus eyes this. probably should have instrumented it... |
| 21:34 | <@ToxicFrog> | a | b == (b % a == 0) ? |
| 21:34 | <@McMartin> | More or less. |
| 21:35 | < Vornicus> | Yes. |
| 21:35 | <@McMartin> | IIRC, divisibility is always defined, even when % is not |
| 21:37 | | * Vornicus is compiling a list of primes. A bit list of primes. |
| 21:38 | < Vornicus> | hey, look, it's interruptable without losing progress. |
| 21:38 | | * Vornicus instruments. |

| 21:55 | <@Vornicus> | I need to learn erlang and haskell and ML, just so I can follow the code that gets thrown around in here. |
| 22:01 | | * Vornicus asks it for the highest prime below 1000, uses that as the maximum index. Should probably do this loop by hand so he doesn't have to rejigger it later. |
| 22:42 | | Lerhir is now known as AnnoDomini |
| 23:10 | | * Vornicus is going through project euler, is on the collatz one. First, aggressively fills from the bottom. This produces nearly 400,000 numbers that when collatzed don't go above 1,000,000. |
| 23:15 | <@McMartin> | Collatz can go to a million without blowing out signed 32-bits. |
| 23:15 | <@Vornicus> | Not surprising. |
| 23:16 | <@Vornicus> | But I was curious about what happens if you limit it to 1,000,000. You get a much larger number of things than I expected. |
| 23:17 | <@Vornicus> | (the longest chain that doesn't break 1M starts at 595800) |
