| 01:47 | < [R]> | ^ How serious? |
| 01:48 | <&McMartin> | An ECC failed but in a way that was correctible, it looks like? |
| 01:50 | < [R]> | Ah, thanks. Time to read up on ECCs. |
| 01:55 | <&McMartin> | ECC = "Error-correcting Code" |
| 01:56 | <&McMartin> | I'm literally pulling the rest of this out of my ass, but the guesses match up, so... |
| 01:56 | <&McMartin> | Memory Controller 4 on the Northbridge's Level 3 data cache had a memory error, but it had one that was trapped by redundant systems and so the original data was successfully reconstructed. |
| 01:57 | <&McMartin> | If you're getting this *constantly* it may be a faulty memory thing that's failing just lightly enough to be... I think the term is "failsoft". |
| 01:57 | < [R]> | Oh, someone linked me this: http://serverfault.com/questions/453186/ecc-errors-in-l3-cache-critical-or-not readhing now |
| 01:58 | <&McMartin> | Sweet, that looks more authoritative than my half-assery |
| 01:59 | <&McMartin> | But yeah, the ultimate result is the same. Hardware's reporting a recoverable failure. |
| 02:01 | < Shiz> | a hardware failure is never good |
| 02:01 | < Shiz> | so I'd look into the sticks at least |
| 02:01 | < Shiz> | maybe run memtest |
| 02:02 | <&McMartin> | Oh yeah, memtest is a thing |
| 02:03 | <&McMartin> | Good plan |

| 02:31 | | * Derakon ponders spell scripts in Pyrel, and specifically how to re-use them with different targeting. |
| 02:31 | <&Derakon> | Right now the temporary-haste script assumes that it's being used as an item, so it accepts the item and the user as parameters, since those are the parameters given to every script that has the trigger condition "item use". |
| 02:32 | <&Derakon> | If I want to use it as a spell cast by a monster, though, then it's a different parameter set. |
| 02:33 | <&Derakon> | I can't think of a clean way to magically derive the information the script needs; best I can manage is to move the shared functionality to a utility function and have the scripts just translate their parameters. |

| 19:22 | < [R]> | What does type() do in JS? |
| 19:22 | <@Tamber> | Releases spiders. |
| 19:23 | <&jerith> | Same as everything in JS. |
| 19:25 | < [R]> | Oh nm, it's defined later in the file |
| 19:25 | | * [R] didn't realize that was allowed |
| 19:50 | <@celticminstrel> | Function definitions are processed before everything else, for some obscure, random reason. :/ |
| 19:50 | <@celticminstrel> | Though I'm pretty sure type() is a built-in...? |
| 19:50 | < [R]> | Maybe in other interpreters |
| 19:50 | < [R]> | typeof is an operator |
| 19:51 | <@celticminstrel> | Oh, it's typeof. |
| 19:51 | | * [R] is using node.js |
| 19:51 | <@celticminstrel> | Okay then/ |
| 19:51 | <@celticminstrel> | ^. |
| 19:51 | | * celticminstrel was probably getting confused with Python or something. |
| 19:52 | < [R]> | Heh |
| 19:52 | < [R]> | Eitherway, looks like type() was just Ext.extend() |
| 20:22 | < RichyB> | celticminstrel: it's so that you don't have to forward-declare functions before calling them. |
| 20:23 | < RichyB> | JS would be even more painful if you always had to carefully order your function declarations so that one never calls another that's lower down than itself in the source file. :P |
| 20:33 | < [R]> | Uhh |
| 20:34 | < [R]> | You can do that in forward declaration languages. |
| 20:34 | <&McMartin> | Which JS is not |
| 20:34 | < [R]> | func a() { b() } func b() { ... } a(); // should work in forward declare just fine. |
| 20:35 | <&McMartin> | In JS you can do it because the binding isn't checked until the call is executed, much like Python. |
| 20:35 | < [R]> | (Note that's specifically a duck-typed FD language) |
| 20:36 | <&McMartin> | JS IIRC moves all declarations to the top of the function they were defined in |
| 20:36 | <&McMartin> | I don't have a JS REPL handy, so I can't test var f = g(); var g = function() { ... } |
| 20:37 | < [R]> | > f = g(); var g = function() { return 1 }; f |
| 20:37 | < [R]> | TypeError: Property 'g' of object #<Object> is not a function |
| 20:37 | <@celticminstrel> | RichyB: Somehow, I don't think JS works that way. |
| 20:38 | <@celticminstrel> | That is, a function can call a function that hasn't been defined yet as long as the second function is defined before the first is called. |
| 20:38 | < [R]> | > var g = function() { return 1 }; f = g(); f |
| 20:38 | < [R]> | 1 |
| 20:38 | < [R]> | > y = x(); function x() { return 2 }; y |
| 20:38 | < [R]> | 2 |
| 20:38 | <@celticminstrel> | So, all you'd have to do is make sure all function declarations are at the top of the file. |
| 20:38 | < RichyB> | Oh yes my bad. |
| 20:38 | < [R]> | Looks like it's dependant on how the function is defined (CM's suggestion made an anon func) |
| 20:39 | <@celticminstrel> | Hm? |
| 20:39 | < [R]> | var g = function() { } // this is an anon function. |
| 20:39 | < [R]> | function g() {} // this isn't. |
| 20:39 | < RichyB> | I was thinking of Pascal where AIUI you actually couldn't do that because the compiler would actually generate the call sites immediately without going back and patching them. |
| 20:39 | <@celticminstrel> | Yeah, only function definitions are processed first, not all function expressions. |
| 20:43 | < RichyB> | Linus' writing style is very funny if you're not on the receiving end of it. http://lwn.net/Articles/190241/ |
| 20:44 | <@Tamber> | :) |
| 20:44 | < RichyB> | I assume that there's a level of sense of humour at which it's possible to read that and not feel insulted by it. |
| 20:45 | < RichyB> | *to be the recipient of that and not feel insulted, even. |
| 20:45 | <@Tamber> | If you're pretty laid back, it's probably okay; might get a chuckle. |
| 20:45 | < RichyB> | I am not that laid back. |
| 20:45 | <@Tamber> | Of course, if it's something you've spent the last 3 weeks' worth of sleepless nights of trying to perfect it, I suppose it's a match in the magazine. |

| 21:38 | < sshine> | I find the maximal deviation from the mean, and I square that. |
| 21:39 | < sshine> | maybe var() also looks at other points and estimates a distribution with another parameter than sigma = max(...)^2 |
