| 01:19 | < kwsn> | hey ToxicFrog, you there? |
| 01:19 | <@ToxicFrog> | Yar |
| 01:20 | < kwsn> | ok, every time i enter java into cmd prompt, it keeps on giving me not valid command, which java install do i need to have? |
| 01:21 | <@ToxicFrog> | Just to run java programs? Java Runtime Environment SE. |
| 01:22 | <@ToxicFrog> | That said, if you're on windows, it may not put it someplace the command line looks by default. |
| 01:22 | <@ToxicFrog> | It probably just associates .class and .jar files with it and calls it a day. |
| 01:23 | < kwsn> | heh |
| 01:24 | < kwsn> | it has done that |
| 01:25 | <@ToxicFrog> | Try something like 'set PATH=%PATH%;C:/path/to/dir/with/java.exe' |
| 01:25 | <@ToxicFrog> | That said, what do you need it for? |
| 01:27 | < kwsn> | i needed it for a class last semester but i ended up doing it on a school computer where it worked (i'm on win 7) |
| 01:29 | <@ToxicFrog> | Aah. But you didn't need the compiler? |
| 01:30 | < kwsn> | i did |
| 01:30 | < kwsn> | java/javac didn't work on here |
| 01:31 | <@ToxicFrog> | Aah. Ok, so first of all, the JRE just comes with java - for javac you need the JDK, Java Development Kit. |
| 01:32 | <@ToxicFrog> | Getting it working from the command line is as simple as setting PATH properly as noted above. |
| 01:34 | <@ToxicFrog> | Alternately, you can use an IDE like Eclipse. |
| 01:34 | < kwsn> | jdk installed, i'll set the path then xD |
| 01:35 | < kwsn> | and shouldn't it be \ instead of / for windows? |
| 01:35 | <@ToxicFrog> | Windows will accept either, actually |
| 01:35 | < kwsn> | that's a change |
| 01:35 | <@ToxicFrog> | It's better to use / in general because (a) it's accepted by OSes that aren't windows, and \ isn't and (b) \ is used as an escape character in a lot of programming languages and shells, leading to paths like c:\\foo\\bar |
| 01:36 | <@ToxicFrog> | It's been like that since at least NT |
| 01:36 | | Attilla [Some.Dude@Nightstar-66744971.threembb.co.uk] has quit [[NS] Quit: ] |
| 01:37 | < kwsn> | so 'set PATH=%PATH%;C:\Program Files (x86)\Java\jdk1.6.0_23\bin\java.exe'? |
| 01:37 | <@ToxicFrog> | No - drop the "java.exe" from that |
| 01:37 | < kwsn> | ah |
| 01:37 | <@ToxicFrog> | try 'echo %PATH%' to see the current value |
| 01:37 | < kwsn> | there we go |
| 01:37 | < kwsn> | thanks |
| 01:38 | <@ToxicFrog> | It's a list of directories, separated by semicolons; when you enter a command it searches those directories for .exe, .bat, .cmd, and .com files with that name. |
| 01:38 | <@ToxicFrog> | ($PATH on *nix works similarly) |
| 01:38 | <@ToxicFrog> | You're welcome :) |
| 01:43 | <@ToxicFrog> | (if you're planning to do a lot of java development, though, seriously look into using an IDE - Java is painful enough as it is, and having builtin documentation and build system alleviates that somewhat) |
| 01:44 | <@McMartin> | (Eclipse is both excellent and free) |
| 01:50 | | Kindamoody is now known as Kindamoody[zZz] |
| 01:50 | < kwsn> | i don't think i'm doing java again fr a while |
| 01:50 | < kwsn> | though i am taking scheme nd prolog next semester |
| 01:52 | <@McMartin> | Scheme is fun |
| 01:53 | < kwsn> | yeah, the one problem with me? I'm not entirely confident in my abilities as programmer, i mean yeah i'm decent at it... but i don't feel like there's much setting me apart from everyne else |
| 01:54 | | * Vornicus totally rocks a problem he had, crushing it down to Ridiculously Easy Linear Time |
| 01:59 | <@ToxicFrog> | kwsn: confidence will come with practice. |
| 01:59 | <@ToxicFrog> | And with seeing how awful your classmates' code is~ |
| 01:59 | < kwsn> | heh |

| 02:08 | <@ToxicFrog> | kwsn: for serious. You're lacking confidence? Half of your classmates don't understand how any of the tools work and will melt down completely the first time they see a new error message. |
| 02:09 | < kwsn> | heh, most of mine aren't bad really |
| 02:09 | < kwsn> | but like i know how to write a sort function, could i name what type it is? probably not |
| 02:12 | <@Vornicus> | oh meh. |
| 02:12 | <@Vornicus> | "it's a sort function. It sorts." |
| 02:13 | <@McMartin> | That question is a question of Computer Science, not programming. |
| 02:13 | <@McMartin> | They're different >_> |
| 02:13 | <@McMartin> | CS is important, but it's as distinct from programming as linguistics is from writing. |
| 02:14 | | * kwsn is SE, not CS :P |
| 02:14 | <@McMartin> | If they aren't teaching you CS material at some point you won't be much of an SE. |
| 02:18 | < kwsn> | they have taught me some, like PLS was more of a CS class |
| 02:18 | <@McMartin> | PLS? EAP. |
| 02:35 | < celticminstrel> | SE? |
| 02:36 | <@McMartin> | SE = Software Engineering |
| 02:36 | <@McMartin> | I can't expand PLS. |
| 03:07 | < kwsn> | programing language structures |
| 03:08 | <@ToxicFrog> | Is that data structures, language theory, or something else entirely |
| 03:08 | <@ToxicFrog> | ? |
| 03:10 | < kwsn> | lang theory |
| 03:11 | <@ToxicFrog> | Aah |

| 05:43 | <@Derakon> | What's it supposed to do, give you a bitwise diff? |
| 05:44 | <@McMartin> | I meant more "internally" |
| 05:44 | <@McMartin> | And yes, if the files share a prefix, a suffix, or are the same size, some benefits could accrue, I think =P |

| 15:29 | <@jerith> | So, unit testing network code in Java. |
| 15:29 | <@jerith> | I have a system that makes calls to various third-party services. |
| 15:30 | <@jerith> | I can stub out the actual network stuff to test most of the functionality, but we have hard requirements about things like latency. |
| 15:31 | <@Derakon[AFK]> | Have another service running on the same box that you can connect to for testing purposes, which other service can be coded to fiddle with delays and so on. |
| 15:33 | <@jerith> | That's kind of where I'm going, although I'd need it running in another thread in my test process. |
| 15:33 | <@jerith> | (There are a bunch of backends and we build this code (which includes running tests) in all sorts of strange places.) |

| 17:08 | < gnolam> | But sadly, there's the Dunning-Kruger effect. :P |
| 17:08 | <@jerith> | This blasted woman I'm supposed to be working with rants about my lack of documentation for a system I'm still trying to build a proof-of-concept prototype for. |
| 17:09 | <@jerith> | Then she yells at me for designing said prototype without her detailed input and oversight. |
| 17:25 | < kwsn> | jerith: that's when you g to her and tell her "you want it done your way, do it yourself" |
| 17:33 | <@jerith> | She's closer to you than to me. |
| 17:34 | <@jerith> | And I've told my boss and my boss' boss that if she doesn't fuck off and let me do my job, they can all find someone else to do it. |
| 17:35 | <@jerith> | She's a difficult person to work with. |
| 17:35 | <@jerith> | AAARGH! *STABSTABSTAB* |
| 17:36 | <@jerith> | This library reads a hostname out of a property file and makes it a constant. Then it uses the constant everywhere. |
| 17:37 | <@jerith> | So I can't inject my own damned server into it for testing without providing the property file it's expecting. |
| 17:39 | <@jerith> | Hrm. It isn't actually marked final. |
| 17:39 | | * jerith shudders and tries replacing it. |
| 17:41 | <@jerith> | Oh. It's an interface. That makes it final. |
| 17:41 | | * jerith bashes his head into the desk a few time. |
| 17:41 | <@jerith> | Why do people do this? |
| 17:42 | <@jerith> | It's a library. It's expected that you might want to actually test some code that uses it. |
| 17:42 | <@jerith> | So you make all the configuration static and require a stupid file in a magic place that you get to read once at startup. |
| 17:42 | <@jerith> | (Well, when the class is loaded. But that's pretty much the same thing here.) |
| 17:47 | <@jerith> | Well. The more recent versio nof the library does it sanely. |
| 17:48 | | * jerith tries getting that. |
