| 02:28 | <@McMartin> | ? |
| 02:38 | < MyCatOwnz> | Hmmmmmm. |
| 02:38 | | * MyCatOwnz offers Stephenie|sad a hug. |

| 03:13 | < MyCatOwnz> | I am perpetually annoyed by people who ought to understand the concept of a noise floor, but fail to. |
| 03:13 | < MyCatOwnz> | It's a kind of low-level irritation. Like being in a room that got farted in ten minutes ago by someone with an onion addiction. |
| 03:14 | <@ToxicFrog> | A noise floor being...? |
| 03:14 | <@ToxicFrog> | A floor that is tuned to make sound when walked on? |
| 03:15 | | * MyCatOwnz headbutts something. |
| 03:15 | | * ToxicFrog eyebrows |
| 03:16 | <@ToxicFrog> | Such things do exist, although I generally hear them called "tuned floors" |
| 03:16 | < MyCatOwnz> | Y'know how stupid people always assume that analogue signals have infinite resolution, because they entirely miss the concept of the fact that there is *always* background noise? |
| 03:16 | <@ToxicFrog> | Aah. |
| 03:17 | < MyCatOwnz> | Noise floor. As in electronics (or any other form of signal processing for that matter) |
| 03:17 | <@ToxicFrog> | And the noise floor is the minimum possible level of background noise for a given signal? |
| 03:17 | <@ToxicFrog> | Or the ambient level? |
| 03:17 | <@McMartin> | I was guessing minimum possible distinguishable signal given a level of noise. |
| 03:17 | < MyCatOwnz> | The ambient level. |
| 03:17 | <@ToxicFrog> | Aah. That would make sense, yes. |
| 03:17 | < MyCatOwnz> | McMartin: technically that's an equivalent definition. |
| 03:18 | <@McMartin> | Good to see my, uh, one class on analog signals from 1997 hasn't gone entirely to waste~ |
| 03:20 | < MyCatOwnz> | McMartin: yay for the practical implications of thermodynamics! |
| 03:26 | | * ToxicFrog gets his event serializer/deserializer working! |
| 03:26 | <@ToxicFrog> | I can now start the server, connect to it, and send a join request. |
| 03:26 | <@ToxicFrog> | At which point it will successfully parse the join request, and then crash because I haven't written the parts that will let me actually create a new wizard object. |
| 03:26 | <@McMartin> | Hee |
| 03:28 | <@ToxicFrog> | (or the events that will let it reject the join request, for that matter~) |
| 03:28 | <@McMartin> | (Clearly that's the first priority; a server that says "go away") |
| 03:28 | | * McMartin commits another UQM patch |
| 03:28 | <@ToxicFrog> | (Indeed.) |
| 03:29 | <@McMartin> | Also, the Play Guitar Hero for Charity event has the Best Name Ever. |
| 03:29 | < MyCatOwnz> | Would not it be easier to put function stubs in than to let it crash? |
| 03:29 | <@McMartin> | Fünde Razor |
| 03:29 | <@McMartin> | MCO: Well, no, because letting it crash takes no effort whatsoever. |
| 03:30 | <@McMartin> | However, refusing requests is actual functionality. |
| 03:30 | <@McMartin> | Since it will presumably be necessary if people try to join into a closed game or whatnot |
| 03:30 | < MyCatOwnz> | McMartin: fair point, but you only get one networking test case done every time you execute the program and set up a connection that way. |
| 03:30 | <@McMartin> | You have to do that anyway unless your protocol is completely stateless. |
| 03:30 | <@McMartin> | Unit tests do tend to start from zero each time. |
| 03:30 | < MyCatOwnz> | I hadn't thought of that. |
| 03:30 | | MyCatOwnz [~mycatownz@Nightstar-379.dsl.in-addr.zen.co.uk] has quit [Quit: Sleeping.] |
| 03:31 | <@ToxicFrog> | Besides which, the test here was "does the deserializer have any obvious bugs" |
| 03:31 | <@ToxicFrog> | And the answer was "no, so far" |
| 03:31 | <@ToxicFrog> | (I haven't tested nested tables yet) |
| 03:31 | <@McMartin> | (Even HTTP isn't completely stateless anymore once you get into The Fun Stuff ;_;) |
| 03:31 | <@McMartin> | (Fortunately, I can force-reset an application without having to cycle the whole web server) |
| 03:32 | <@ToxicFrog> | Anyways. Creating the events that will let it deny connections is fortunately trivial since they don't actually have any internal state apart from some deserialization metainfo. |
| 03:32 | <@ToxicFrog> | But that can wait until tomorrow. |
| 03:32 | <@McMartin> | Hmm. |
| 03:32 | <@McMartin> | I should probably look into making dinner at some point. |
| 03:33 | <@McMartin> | Heh. UQM "ChangeLog" file is up to version 537. |
| 03:33 | <@McMartin> | I wonder what our initial SVN revision will end up being. |
| 03:35 | | Chalcedon [~Chalceon@Nightstar-869.bitstream.orcon.net.nz] has quit [Ping Timeout] |
| 03:52 | <@ToxicFrog> | McMartin: on the topic of Hidden Palace: |
| 03:53 | <@ToxicFrog> | (1) Knuckle's version is just a straight run through a few screens to the teleporter |
| 03:53 | <@ToxicFrog> | (2) It uses the same music as Lava Reef 2, which would be why it's listed as "Hidden Palace" in the music dump |
| 03:54 | <@McMartin> | (1) Yes, as I said, you'd likely notice some changes |
| 03:54 | <@ToxicFrog> | ...oh that's not good at all |
| 03:58 | <@ToxicFrog> | Well, you said I'd notice some changes in Sky Sanctuary, and I'd approve of the changes in Hidden Palace. |
| 03:59 | <@ToxicFrog> | IMO, "four screens of catwalk, then teleporter" < "duel with your nemesis" |
| 04:00 | <@McMartin> | Well, in terms of "pain to get through" |
| 04:00 | <@McMartin> | The level doesn't even exist, because it's basically his house =P |
| 04:01 | <@ToxicFrog> | And Knuckles takes Angel Island INTO ORBIT! To rain down massive kinetic death upon those fools from the Institute! |
| 04:02 | <@ToxicFrog> | I approve of any ending that involves a massive floating island flying into orbit. |
| 04:04 | | Stephenie|sad is now known as Stephenie |
| 04:07 | <@McMartin> | I thought the normal sonic ending resulted in relaunching Angel Island, too |
| 04:07 | <@McMartin> | Or was that not orbit? |
| 04:08 | <@ToxicFrog> | It rises from the ocean to the cloud layer. |
| 04:08 | <@McMartin> | And yeah, that's why Breathtaking Vision is good, because it is clearly Music To Launch Massive Floating Islands By. |
| 04:08 | <@ToxicFrog> | In this, it's already in the cloud layer, and Knuckles decides that since he can BREATHE IN SPACE, why not go all the way? |
| 04:09 | <@McMartin> | What I want to know is what Angel Island is doing on the ground in S3 Level 1 when the Master Emerald isn't actually stolen until S3K Hidden Palace. |
| 04:09 | <@ToxicFrog> | The Death Egg crash-landing on it damaged and/or overloaded its antigravity systems, IIRC. |
| 04:09 | <@McMartin> | That works. |
| 04:09 | <@ToxicFrog> | Which is also why Sonic and Tails are visiting: they traced the Death Egg's crash and want to finish the job. |
| 04:10 | <@McMartin> | (Alternately, Sonic's yoinking of the Chaos Emeralds forced it to auxiliary power) |
| 04:10 | <@McMartin> | Since it clearly needs both the Master and all the Chaos Emeralds to launch the thing. |
| 04:10 | <@ToxicFrog> | I'm fairly sure that the death egg crashing is actually the canonical explanation, hence the "IIRC". |
| 04:10 | <@McMartin> | Ah, OK. |
| 04:11 | | * McMartin definitely remembers seeing the Death Egg lighting up turning Crystal Caves into Lava Reef B. |
| 04:11 | <@ToxicFrog> | Yeah. This is after it crashes for the /second/ time, on its side this time. |
| 04:11 | <@ToxicFrog> | (following Launch Base Zone) |
| 04:12 | <@ToxicFrog> | At which point it's even more badly damaged than before /and/ Robotnik doesn't have time to rebuild it because Sonic is practically on top of him now, so he yoinks the Master Emerald instead. |
| 04:13 | <@McMartin> | Right. |
| 04:13 | <@McMartin> | Also, this time he thoughtlessly stocked the Death Egg with rings, unlike in SC2. |
| 04:17 | <@ToxicFrog> | Maybe he has a new, improved, ring-fueled power source? |
| 04:18 | <@ToxicFrog> | ...oh, wait. Except that by the time you're on the Death Egg, he already has the Master Emerald installed. |
| 04:18 | <@ToxicFrog> | New theory: the Master Emerald generates rings. |
| 04:18 | <@ToxicFrog> | The ability of Hyper Mecha Sonic to fire rings at lethal velocities would appear to support this~ |
| 04:20 | <@ToxicFrog> | *** Tails got a Chaos Emerald *** |
| 04:29 | <@ToxicFrog> | And now, leaving Angel Island Zone with 7 lives, 4 continues, and 200,000 points, I conclude that it is bedtime. |

| 21:15 | < Janus> | This is going to sound lame, but... if one converted the value of 'a' to an integer, what value would it most likely be? |
| 21:15 | < Zomchok> | Hmm. 97? |
| 21:17 | < Janus> | Would it follow that 'b' is to 98 as 'c' is to 99, etc.? |
| 21:17 | | Zomchok is now known as AnnoDomini |
| 21:17 | < AnnoDomini> | Probably. |
| 21:18 | < Janus> | Are you sure it's 97 then..? |
| 21:18 | < AnnoDomini> | Reasonably. |
| 21:19 | < Janus> | Thank you~ |
| 21:20 | < AnnoDomini> | http://www.neurophys.wisc.edu/comp/docs/ascii.html |
| 21:22 | | * Janus ponders the sanity of "total[pull - 97]++;" |
| 21:23 | < MyCatOwnz> | Janus: what language are you working in? |
| 21:23 | < MyCatOwnz> | If you're in C/C++: total[pull - 'a']++; will be equivalent. |
| 21:23 | < MyCatOwnz> | ...except on machines with non-ASCII character sets, in which it'll continue to be correct. ^_^ |
| 21:24 | < Janus> | ... |
| 21:24 | < Janus> | Genius! |
| 21:33 | < MyCatOwnz> | Janus: yes, on the part of a few old very hackers. |

| 21:50 | <@jerith> | Janus: What are you trying to achieve? |
| 21:51 | < Janus> | Mmm... it's supposed to read a .txt file for a few lines, read the characters on each line, and tally how many each letter occurs. |
| 21:52 | <@jerith> | Ah. |
| 21:52 | <@jerith> | That's ok, then. :-) |
| 21:53 | < Janus> | If anything other than a lower-case alphabet character is spotted, the program's sunk, but there's very little time for any error checking, as it's to leave my desk today. |
| 21:54 | <@ToxicFrog> | ... |
| 21:54 | < MyCatOwnz> | Janus: #include <ctype.h> and use the tolower() function. |
| 21:54 | <@ToxicFrog> | Or just support all byte-wide characters. |
| 21:54 | <@ToxicFrog> | unsigned int total[256]; |
| 21:55 | <@ToxicFrog> | total[pull]++; |
| 21:55 | < MyCatOwnz> | Janus: also, you will need to handle ' ' '\n' '\t' '\f' '\g' and many many more. |
| 21:55 | | * jerith nods. |
| 21:55 | < MyCatOwnz> | Do it TF's way. |
| 21:56 | < Janus> | I've the newline character and EOF handled... though Mr. Frogs seems quite a score saner. |
| 21:57 | <@ToxicFrog> | Also, look into isalpha(3) and related functions, also in <ctype.h> |
| 21:57 | <@jerith> | I was about to suggest something similar when my network fell over. |
| 21:59 | < MyCatOwnz> | Heheheh. while(total(total[pull++]++)) { ; } |
| 21:59 | < MyCatOwnz> | Errr... |
| 22:00 | < MyCatOwnz> | while ( total[pull++]++ ) { ; } |
| 22:03 | < Janus> | I have the sudden urge to stick my fingers through my eyes and swirl my brain around... |
| 22:03 | < Janus> | What's that do~ |
| 22:04 | < MyCatOwnz> | Not much, it's wrong. |
| 22:05 | < Janus> | Oh... it looked kind of right though... |
| 22:05 | < MyCatOwnz> | That's what's alarming about it. |
| 22:06 | < MyCatOwnz> | while ( someasciizstring[index] ) { total[index++]++; } |
| 22:07 | < MyCatOwnz> | Given that it's preceeded by: char* someasciizstring = readline("Prompt: "); /* need to #include <stdio.h>, <readline/readline.h> and <readline/history.h> */ |
| 22:07 | < MyCatOwnz> | int index = 0; and finally: |
| 22:07 | <@ToxicFrog> | No, that's wrong too. |
| 22:08 | <@ToxicFrog> | You want { total[someasciizstring[index++]]++; } inside the loop body. |
| 22:08 | < MyCatOwnz> | D'oh. I see yes. |
| 22:08 | < Janus> | It looks sexy, but I'd probably forget what it did after dinner. |
| 22:08 | < MyCatOwnz> | Janus: (with TF's correction) that's actually the most natural way to do it, to my eyes. |
| 22:09 | <@ToxicFrog> | Janus: it uses the character at index as an index into the total[] array, increments that, then increments index (thus moving on to the next character in the string) |
| 22:10 | <@ToxicFrog> | When the character at index is 0 (NUL) it exits the loop. |
| 22:10 | < MyCatOwnz> | annnnnd finally: int total[256]; memset (total,0,256); |
| 22:12 | <@ToxicFrog> | unsigned int. |
| 22:12 | <@ToxicFrog> | And I think statically allocated arrays are guaranteed to be initialized to zero, but don't quote me on that. |
| 22:12 | <@McMartin> | I wouldn't trust any default initialization in C |
| 22:13 | < Janus> | I'll splice a for() loop to make certain. |
| 22:13 | <@ToxicFrog> | ... |
| 22:13 | <@ToxicFrog> | What's the for() loop for? |
| 22:13 | <@McMartin> | memset works. |
| 22:13 | <@ToxicFrog> | If your answer is "initializing the array", that's what MCO's memset() call is for. |
| 22:13 | < Janus> | Oh. Well, that sames time. |
| 22:14 | <@ToxicFrog> | Alternately, you could create it in the heap with calloc(), which also guarantees zero-initialization. |
| 22:16 | < Janus> | Alright, that should work way better then. |
| 22:17 | <@ToxicFrog> | What's this needed for, anyways? |
| 22:17 | <@ToxicFrog> | I mean, really, this sort of thing is perhaps three lines of awk. |
| 22:18 | | * ToxicFrog departs! |
| 22:18 | < Janus> | It's for a friend of mine, he just wants to see a tally program~ |
