| 14:38 | <@Vornicus> | Why I love *nix: sudo !! |
| 14:39 | | * jerith usually goes <up> C-a sudo <space> |
| 14:40 | <@Vornicus> | I didn't know that worked. |
| 14:41 | <@jerith> | Normal commandline history editing. |
| 14:41 | <@ToxicFrog> | Use of Home instead of ^A is preferred, tho. |
| 14:42 | <@jerith> | ToxicFrog: Yes, but Home often fails due to terminal weirdness on ssh connections. |
| 14:42 | <@jerith> | Also, substitute C-a a in a screen. |
| 14:43 | | * Vornicus is not exactly conversant with readline. |
| 14:43 | <@jerith> | Readline is very handy. |
| 14:43 | <@jerith> | C-_ rocks. |
| 14:43 | <@ToxicFrog> | Odd. I've never had problems with home. |
| 14:44 | <@ToxicFrog> | What does ^_ do? |
| 14:44 | <@jerith> | Undo. |
| 14:45 | <@ToxicFrog> | Vornicus: it's pretty sweet. In particular, up down left right home end delete all work as expected, and ^V followed by anything inserts a literal character (or string). |
| 14:45 | <@Vornicus> | so ^v backspace gives an actual... |
| 14:46 | <@Vornicus> | /sweet-ville/ |
| 14:46 | <@jerith> | C-w deletes left until whitespace, M-d deletes right until non-alphanumeric (yes, they're different -- no idea). |
| 14:46 | <@ToxicFrog> | Works for sequences, too; ^V PgUp on my terminal generates ^[[5~ |
| 14:47 | <@Vornicus> | /with sweet sauce/ |
| 14:47 | <@jerith> | C-f and C-b are char forward and back respectively (same as left and right arrows). |
| 14:47 | <@ToxicFrog> | jerith: "foo bar baz-M-d will delete to the start of your quote, etc. Occasionally useful. |
| 14:47 | <@ToxicFrog> | (at least, on terminals where it works, which doesn't include mine) |
| 14:48 | <@ToxicFrog> | Oh, wait |
| 14:48 | <@ToxicFrog> | Delete right |
| 14:48 | <@ToxicFrog> | Weird. |
| 14:48 | <@jerith> | M-f and M-b are word left and right. (C-left and C-right do the same.) |
| 14:49 | <@ToxicFrog> | I prefer not to use ^W, since every single graphical app in existence appears to have that mapped to exit. |
| 14:49 | <@jerith> | There are more, but I forget them. |
| 14:49 | <@jerith> | ToxicFrog: That annoys me. |
| 14:50 | <@ToxicFrog> | Yes. Likewise. |
| 14:50 | <@ToxicFrog> | If I wanted to exit I would type ^D. |
| 14:51 | <@jerith> | You can turn it off in GTK apps, iirc. |
| 14:51 | <@jerith> | But not in Thunderbird. |
| 14:51 | <@jerith> | Which at least gives you a confirmation. |
| 14:53 | <@Vornicus> | I think the best thing about Mac's Terminal is that the gui shell accelerators do not ever collide with terminal stuff. |
| 14:56 | <@Vornicus> | so cmd-[q|w|x|c|v|a|p|s|o|n] all work just fine. |
| 14:57 | | * jerith goes off to watch Stardust with friends. |
| 15:45 | <@ToxicFrog> | Vornicus: so there's nothing else that uses cmd-q, say? |

| 19:31 | <@Vornicus> | TF: in the Terminal, no |
| 19:31 | <@Vornicus> | cmd-q is the standard command for quitting. |
| 19:32 | <@Vornicus> | But the terminal doesn't, in itself, know about anything involving cmd. |
| 19:32 | <@ToxicFrog> | Yes, and it's the same for all the terminal emulators I use. |
| 19:33 | <@Vornicus> | So you can use shift and control and alt like you're talking exclusively to a terminal |
| 19:33 | <@ToxicFrog> | I avoid using stuff like ^W because things go Badly Wrong if, say, I accidentally give the wrong window focus. |
| 19:33 | <@ToxicFrog> | Or if NX wackiness means that multiple windows are recieving my keystrokes. |
| 19:33 | <@ToxicFrog> | Or if I'm using xchat and habitually use ^W. |
| 19:33 | <@ToxicFrog> | Etc. |
| 19:33 | | * Vornicus isn't sure we're talking on teh same wavelength... |
| 19:35 | <@ToxicFrog> | None of the terminal emulators I use have collisions with readline shortcuts. |
| 19:35 | <@ToxicFrog> | However, other programs do. |
| 19:35 | <@ToxicFrog> | It is possible for me to either (a) be typing in one of those programs instead of, or as well as, a terminal without realizing it or (b) reflexively attempt to use shell idioms in non-shell programs. |
| 19:36 | <@ToxicFrog> | Thus, stuff that will trash other programs if they recieve it by mistake, ^W and ^Q most especially, is to be avoided. |
| 19:36 | <@Vornicus> | on Mac nearly all commands are done with cmd, which means almost no programs collide. |

| 19:37 | <@Vornicus> | see? |
| 19:38 | <@ToxicFrog> | ...oh, wait. |
| 19:38 | <@ToxicFrog> | <Vornicus> so cmd-[q|w|x|c|v|a|p|s|o|n] all work just fine. <-- those are GUI shortcuts, not some weird aliasing of ctrl? |
| 19:39 | <@Vornicus> | QUI shortcuts. |
| 19:39 | <@Vornicus> | quit close cut copy paste select-all print save open new |
| 19:40 | <@ToxicFrog> | Ok. |
| 19:40 | <@ToxicFrog> | Now it makes sense. |
| 19:40 | <@ToxicFrog> | Yes, that is useful. |
| 19:41 | | * Vornicus wonders how he typo'd GUI like that. |
| 19:41 | | * ToxicFrog writes thus in this documentation: "Warning: this will take a long time. A very long time. Bring a packed lunch and as much CPU time as you can carry." |
| 19:42 | <@Vornicus> | hee |
| 19:43 | <@ToxicFrog> | (specifically, the use of a genetic algorithm to fine-tune the ant colony optimization - it has to evaluate each chromosome by repeatdly running ACO with those parameters and averaging the results) |
| 19:43 | <@Vornicus> | I take it the ant colony thing takes rather a while in itself |
| 19:43 | <@ToxicFrog> | Yes. |
| 19:43 | <@ToxicFrog> | It's wicked fast compared to exhaustive search, but not all that hot in absolute terms. |
| 19:44 | <@ToxicFrog> | And the time it takes is a function of graph size (fixed, here), ant count (can be up to 64) and iteration count (ditto) |
| 19:45 | <@ToxicFrog> | And it runs this eight times for each chromosome in the population. Per generation. |
| 19:45 | <@ToxicFrog> | Ooo. That's a promising chromosome. |
| 19:45 | <@ToxicFrog> | ACO 1278 1320 1339 1342 1326 1319 1313 1351-> 1323.500000 |
| 19:46 | <@ToxicFrog> | 1272 is the optimal path. |
| 20:05 | | Chalcedon is now known as ChalcyAFK |
| 21:26 | | * ToxicFrog , having played two levels of We Love Katamari, finished a lab in another course, created and eaten a grilled cheese sandwich, and gone grocery shopping, returns to find that the GA has done 1.22 generations. |
| 21:27 | <@Vornicus> | heh |
| 21:27 | <@ToxicFrog> | ...oh, hey. |
| 21:27 | <@ToxicFrog> | That might have something to do with it. |
| 21:28 | <@ToxicFrog> | The upper bound on ant count and number of iterations was accidentally set at 255 rather than 63. |
