| 06:11 | <&ToxicFrog> | From a conversation using restaurants as metaphors for programming languages and libraries |
| 06:12 | <&ToxicFrog> | <bobthecheese> Fuck that, I'm a customer at that poorly run cafe[pylonsproject.org] which makes really tasty, healthy food, and they encourage you to pick your own ingredients, but half the time they're out of season. Also the menu is several years out of date. Sure, the service is shitty, half the time you can't even get a basic sandwich, and no-one is able to tell you how you're meant to order (you're meant to just know already), bu |
| 06:12 | <&ToxicFrog> | t I still love it. |
| 06:12 | <&ToxicFrog> | <bucketmouse> Personally I like to eat at mcdonalds[php.net] except half the time there's no electricity, I can always hear a baby crying from somewhere even if the restaurant is completely empty, and one time I ordered fries and got half of a human head instead |
| 06:12 | <&ToxicFrog> | <bucketmouse> actually no fuck that |
| 06:16 | < Xires> | ToxicFrog; have you, by chance, used protothreads before? |
| 06:17 | <&ToxicFrog> | I've never even heard of protothreads. |
| 06:19 | < Xires> | ToxicFrog; oh, umm.. http://dunkels.com/adam/pt/ - appears to expand on Duff's Device |

| 06:25 | < Xires> | ToxicFrog; very coroutine-like..I think |
| 06:26 | < Xires> | at least it appears to be |

| 07:57 | | * Vornicus determines that there is a better way to do this than simulation, which is good because simulation was a pain in the ass. |
| 08:05 | <@Azash> | Out of curiosity |
| 08:06 | <@Azash> | To what degree do thread packages in major languages make use of kernel threads? |
| 08:08 | < ReivDriod> | Vorn - what be you simulating? |
| 08:10 | <~Vornicus> | ReivDriod: you may or may not remember that I've been working on a 4e skill selection tool; previous to my current thought, the way I would determine whether a selection could be made was by looking in the complete list of possible outcomes of simulated skill selection. |
| 08:12 | | Attilla [Attilla@Nightstar-aced750e.range86-184.btcentralplus.com] has quit [Ping timeout: 121 seconds] |
| 08:13 | < ReivDriod> | I... See |
| 08:13 | <~Vornicus> | (the skill selection ui is a bunch of dropdowns; if a given change in a particular dropdown would create an illegal selection, that change is disabled.) |
| 08:13 | < ReivDriod> | That is a slightly convoluted way to do it, yes. |
| 08:14 | <~Vornicus> | (so previously I would disable individual skills by comparing the selection list with that change made to the complete list etc etc) |
| 08:18 | <~Vornicus> | Now I've figured out a better way: I can count the number of selections made at each 'level' -- a class has (usually) a set of "primary" skills, a set of "regular" skills, and then a set of non-class skills -- and compare that against the number of selections hat need to be made. I can then disable skills in groups if changing to a skill in that group would make the selection miss the requirements |
| 08:18 | < ReivDriod> | That is a sensible way to do it, yes. |
| 08:19 | <~Vornicus> | HTML even gives me this ability straight up: put your options in an optgroup and you can disable the optgroup as a whole. |
| 08:20 | < Xon> | Azash, fairly closely. on a general purpose OS you generally want to use kernel threads since they are hardware threads which makes stuff a lot easier. But with stuff like automatic threadpooling, hyperthreading, etc, it's really an implementation detail |
| 08:20 | | * Azash nods |
| 08:21 | < Xon> | It's really easy to break assuptions if your code assumes user-threads & stack messing around isn't happenig. Obviously doesn't apply to managed or scripting languages |
| 08:21 | <@Azash> | Well, was more wondering re. using multiple cores |
| 08:23 | < Xon> | pure user-threads made a lot more sense when there was only 1 hardware thread |

| 08:24 | | * Vornicus gets the code to tell where the requirement limitations are; now he need to get it to apply those limitations to the existing dropdowns. |
| 08:33 | <~Vornicus> | hm. Okay so I have two lists, something like a = [1,5,3,6,9,2,8,4] and b = [3,5,10], and I want to generate the list [3,5,3,10,10,3,10,5] -- for each element k in a, the new list has the smallest element x in b s.t. x >= k |

| 21:30 | < ErikMesoy> | I spent a long time being confused by "style = wx.TE_READONLY | wx.TE_MULTILINE" and poking at the magic numbers that these caps-constants represented before realizing that the *single* bar was doing bitwise OR, hence combining the lot of them.
