| 06:17 | <@Vornicus> | Reiver: did you figure out your tree thing? |
| 06:21 | <~Reiver> Vornicus: I figured out what you did to it, but it indicates that I still really have no clue what I'm doing. :/ |
| 06:21 | <~Reiver> Why is trees so hard for my brain? ;_; |
| 06:21 | | Serah [Z@Nightstar-11344bdb.customer.tele.dk] has quit [Ping timeout: 121 seconds] |
| 06:21 | <~Reiver> Not least because once I have the tree, I need to start pulling Stupid Pet Tricks with it. |
| 06:25 | <~Reiver> Basically I need to get this tree up and working so I can start treating it as a component of a trie - and then that trie has some really funky logic tricks applied to it. |

| 07:08 | <@Vornicus-Latens> | I don't know why trees are so hard for your brain. |
| 07:08 | <@Vornicus-Latens> | But once you finish with the tree you should be able to just ignore its treeitude and run with it. |
| 07:13 | <~Reiver> The problem is once I have the tree |
| 07:13 | <~Reiver> I then need to use the tree to make an even bigger tree with some funky logic puzzle stuff. |
| 07:13 | <~Reiver> LZW alograthm involves working out what the last letter was by what the next one is. |
| 07:16 | <@Vornicus-Latens> | Aha |
| 07:17 | <~Reiver> This worries me immensely. |
| 07:17 | <~Reiver> Oh, and it's also not sorted, I think? |
| 07:17 | <~Reiver> Er. Damnit, where's my notes |
| 07:22 | <@Vornicus-Latens> | The tree, once you've got the code working, remains sorted. the trie is a different sack of potatoes; I don't entirely know what kind of stuff LZW does there. |
| 07:23 | <@Vornicus-Latens> | But that's sort of the trick - once you have the data structure together, /it works forever/ |
| 07:23 | <@Vornicus-Latens> | And you usually don't have to think about it. |
| 07:24 | <~Reiver> hrnm. |
| 07:24 | <~Reiver> So does my little Tree require anything further? |
| 07:29 | <@Vornicus-Latens> | You may (or may not!) need a traverse; this is probably the hardest part, and you'd adjust it according to the setup of the remainder of the system. Probably best bet is to make a vector that you pass around in a second parameter to the function and then return it when you're done. Look at my binary tree's "in_order" function to see how it goes. |
| 07:30 | <@Vornicus-Latens> | ....seems to have gone missing from the pastebin. Ah well. |
| 07:30 | <@Vornicus-Latens> | I desperately need sleep. |
| 07:31 | <~Reiver> OK, goodnight Vorn |
| 07:32 | <~Reiver> If I could ask a favor of you, I'd request you look into the LZW alograthm, as done using a trie (rather than just a list; that's the decompressor but we're expected to have one of each). |
| 07:33 | <@Vornicus-Latens> | ok |
| 07:33 | <~Reiver> If only so that way there's a chance it can be explained, because my lecturer is a great guy, but geez he's hard to follow~ |

| 15:57 | <@ToxicFrog> | Reiver: if you understand LZW using a list, LZW using a tree is identical |
| 15:57 | <@ToxicFrog> | (at least from the point of view of the compressor/decompressor) |
| 15:57 | <@ToxicFrog> | The only difference is that it calls find/insert on a tree rather than a list when updating/searching in the dictionary. |
| 15:58 | <~Reiver> but but but trees |

| 18:31 | <@ToxicFrog> | FUUUUUUUUCKKKK YOUUUUUUUUUUUUUUU |
| 18:31 | <@ToxicFrog> | . |
| 18:33 | <@McMartin> | Obviously you are in need of quality time with condescending Debian enthusiasts. |
| 18:34 | <@McMartin> | The first thing they will tell you is that despite it being the only command that ever appears in sample shell scripts and sample commands, apt-get and apt-cache should never actually be used on their own. |
| 18:34 | <@ToxicFrog> | Synaptic (which I tried first) has the same problem. |
| 18:34 | <@McMartin> | Everyone[*] knows that aptitude is the proper interface to APT-based repos. |
| 18:35 | <@McMartin> | Which is itself a baffling pile of inconsistent syntax or insanely-stateful curses interface |
| 18:37 | <@ToxicFrog> | (the problem, specifically, is that there appears to be no way to say "install this package, but do not install the other 150MB of updates that are pending") |
| 18:38 | <@ToxicFrog> | And now it's managed to completely fuck itself to thepoint where I can't install anything! |
| 18:39 | | * ToxicFrog decides to use Puppy instead |
| 18:40 | <@ToxicFrog> | Also, what's the footnote? |
| 18:42 | < PinkFreud> | ToxicFrog: that's because those updates were already selected for installation |
| 18:42 | < PinkFreud> | you'll need to use dselect to tell it *not* to install those |
| 18:46 | <@ToxicFrog> | Too late |
| 18:47 | <@ToxicFrog> | hopefully I'll remember that for next time |
| 18:50 | <@McMartin> | [* meaning 'nobody, as Debian enthusiasts have kept its usage at oral tradition levels for years'] |
| 18:51 | <@ToxicFrog> | Anyways. Now that I have Puppy booted and am resizing /home, I solicit recommendations for laptop Linux distros that are not SUSE, Fedora, Lunar, Ubuntu, or Mint. |
| 18:52 | < PinkFreud> | uh, it's documented. |
| 18:53 | <@McMartin> | PinkFreud: It is |
| 18:53 | <@McMartin> | But despite being, AFAICT, what everybody uses, it's never the one that's recommended by docs. |
| 18:53 | <@McMartin> | It's always "to install this program type apt-get ...." |

| 21:55 | <@ToxicFrog> | From the command line? grep |
| 21:55 | <@ToxicFrog> | grep pattern files |
| 21:56 | <@ToxicFrog> | Defaults to basic regular expressions; use 'egrep' for extended and 'fgrep' for fixed strings. |
| 21:56 | <@ToxicFrog> | Use grep -r to recursively search entire directories. |
| 21:56 | <@ToxicFrog> | Check the man page for all the gory details on how to do things like context lines, line number reporting, what to do with binary files, etc. |
