| 00:23 | <@ToxicFrog> | Vornicus: how does this differ from a normal tree? |
| 00:27 | <@Vornicus> | TF: a normal tree, you're making a direct comparison on the whole string, essentially; in a trie, you're making a comparison on only a substring each time -- or, really, the character indexed by your current depth of the tree. |
| 00:29 | | Derakon[AFK] is now known as Derakon |
| 00:30 | <@Vornicus> | so if you want to differentiate between "cheese" and "cheat", for instance, you start at the root, go down "c", then "h", then "e", and then there's the difference -- from there cheese would go down "e" again and cheat would go down "a" |
| 00:31 | <@Vornicus> | It's especially useful when you're getting your string one character at a time - T9, or live filtering like firefox or chrome's find feature. |
| 00:34 | <@Vornicus> | It means that any string has all the other strings it starts below it, and that each comparison is one character long. |
| 00:35 | <@Vornicus> | and also that each node holds only one character -- a significant space savings over either length-and-characters or null-terminated strings, especially when a great many strings start the same way. |
| 00:45 | <@Vornicus> | (in contrast: each node in a binary or b-tree contains the entire string to compare to, and you must compare the entire string at each level (shortcircuits aside), and "fort" can appear before "for" for a variety of reasons.) |

| 10:15 | <@AnnoDomini> | Are there any good DOS emulators out there. 'Good' defined as being capable of handling assembly programming. DOSBox can apparently handle running the stuff I program, but cannot run FASM for want of a 32-bit real mode. |
| 10:25 | <@AnnoDomini> | And where the hell is dosbox.conf on Debian? |
| 10:27 | <@TheWatcher> | ~/.dosbox/ ? |
| 10:29 | <@AnnoDomini> | Wasn't such a thing. I created a new default file in there just now. How do I modify the launchers in the foot-menu in Debian? |
| 10:29 | <@AnnoDomini> | I want to make it so the launcher uses this configuration file. |
| 10:36 | | * AnnoDomini tries to find some sort of option that will allow better capabilities in the default config file. |
| 10:41 | | You're now known as TheWatcher[afk] |
| 10:48 | <@McMartin> | DOSBox is the best you can hope for, if you want Actual DOS |
| 10:48 | <@McMartin> | You almost certainly do not want Actual DOS in the real world and would do much better with NASM or MASM. |
| 10:50 | <@AnnoDomini> | This isn't the real world. This is academia. We're using FASM with FreeDOS, but to use that, I'd have to reboot, which is annoying. |
| 10:50 | <@AnnoDomini> | Right now I'm trying to understand how to install the Linux version of FASM. |
| 10:52 | <@McMartin> | That said, I had the impression that "32-bit real mode" was something of a contradiction in terms? |
| 10:52 | <@McMartin> | I know of 16-bit real mode and 32-bit protected mode with the flat memory space |
| 10:55 | <@AnnoDomini> | Well, it's what the error message says. |
| 11:24 | <@Kazriko> | There's a new system for running apps with a Dos level of multitasking btw. I guess it's released tomorrow by apple... |
| 11:26 | | * Kazriko remembers writing dos apps in MASM for academia... |
| 11:29 | <@Kazriko> | of course, when I was writing real dos apps, I was using turbo pascal... |
| 11:36 | | * AnnoDomini is using a gnome text editor to edit the ASM file, a terminal window to run fasm to compile to .fas, and then DOSBox to link and run it. |

| 12:04 | < Pseudonym-V> | who u asking ? |
| 12:04 | <@AnnoDomini> | Anyone who knows the answer. |
| 12:06 | < Pseudonym-V> | well i suggest you go to google and type that in - you may find an answer |
| 12:08 | <@AnnoDomini> | I have. It was the first thing I tried. |
| 12:10 | < Pseudonym-V> | lol - sorry dude i really dont know |

| 12:13 | <@AnnoDomini> | Hmm. A random Russian site contains the answer. It seems that it's a prefix to use ECX rather than CX for loops. |
| 12:15 | < Pseudonym-V> | idk |

| 19:01 | < Bobsentme> | dear professor: F-OFF-and DIE IN A FIRE. -Sincerely, Bob. |
| 19:06 | < Bobsentme> | There is a rather complicated application being run almost entirely via JSP. |
| 19:07 | < Bobsentme> | When I explained we need to do some things to it to make it run the stuf the professor asked for, I was informed: |
| 19:07 | < Bobsentme> | 1) No. |
| 19:07 | < Bobsentme> | 2) Hell no, lets run the entire thing on 1 page. |

| 19:25 | < cpux> | Ehh. It ain't my line. It came from a co-worker in response to an internal project tracking system at my work that was untested, inadequate for what we needed, and littered with bugs that our IT likes to blame on user error. |

| 21:12 | <@AnnoDomini> | Might anyone know where I can find a table of protected mode exceptions WITH detailed descriptions? |
| 21:12 | <@AnnoDomini> | I need to know, for example, if a given exception returns an error code or not. |
| 21:12 | < celticminstrel> | Buh? |
| 21:14 | <@AnnoDomini> | Which part is unclear? |
| 21:14 | | * AnnoDomini is looking on Google with no real results. |
| 21:15 | <@McMartin> | Intel's IA32 chip manual would be my first stop, honestly >_< |
| 21:15 | < celticminstrel> | Well, I have zero context for your question. |
| 21:15 | <@AnnoDomini> | I think I actually have that document, somewhere. |
| 21:16 | < celticminstrel> | Though, to be honest, it sounds like the sort of thing I wouldn't know anyway... |
| 21:19 | <@AnnoDomini> | Yay, I have found what I need. |
| 21:19 | < celticminstrel> | Yay! |
| 21:20 | <@AnnoDomini> | Now to continue my LP. |
| 21:52 | <@AnnoDomini> | Hmmm. I need to rename files en-masse. |
| 21:56 | < PinkFreud> | within code? from the shell? if the latter, which OS? |
| 21:59 | <@AnnoDomini> | I'm on Debian 5. I want to rename all files within a directory to be renamed, so that their common prefix is skipped (leaving only the parts that differ and the extension). |
| 22:00 | <@AnnoDomini> | Alternatively, simply having them named 1.jpg, 2.jpg, 3.jpg and so forth also works. |
| 22:00 | < PinkFreud> | ahh. assuming you're using a bourne-compatible shell (bash is default on debian) - |
| 22:01 | < PinkFreud> | for file in *; do echo mv -v $file ${file#prefix}; done |
| 22:01 | < PinkFreud> | replace 'prefix' with the prefix you want stripped |
| 22:02 | < PinkFreud> | if you're happy with how that looks, remove the 'echo' and run it again |
| 22:03 | <@AnnoDomini> | Okay, two things. First, how do I use that? Second, do I have to escape spaces in the prefix? |
| 22:06 | < PinkFreud> | er |
| 22:06 | < PinkFreud> | as to how you use it, one typically types it in via the keyboard :) |
| 22:06 | < PinkFreud> | as for spaces, try: |
| 22:07 | < PinkFreud> | for file in *; do echo mv -v "$file" "${file#prefix}"; done |
| 22:07 | < PinkFreud> | again, replace 'prefix' with your string |
| 22:08 | <@AnnoDomini> | Okay, but I've never used bash before. I put this in a file, right? With #!/bin/bash as the first line or something? |
| 22:08 | <@TheWatcher> | you can just type it as-is at the terminal prompt |
| 22:09 | <@TheWatcher> | No need to put it into a file. |
| 22:12 | <@AnnoDomini> | Okay, I had to put quotes around the prefix to get what I wanted. |
| 22:13 | <@AnnoDomini> | Thank you. |
| 22:26 | < PinkFreud> | np |
| 22:26 | < PinkFreud> | make sure you run that w/o the 'echo' |
| 22:32 | <@AnnoDomini> | I did. |
