| 00:14 | <~Vornicus> | let's assume I've never been to ifmud |
| 00:16 | <&McMartin> | There was a discussion over whether shadowed variable names are intrinsically evil or not |
| 00:16 | <&McMartin> | And the FP guys were all "of course they aren't, they're mandatory" and everyone else was all "of course they are, why is this ever allowed" |
| 00:18 | <~Vornicus> | I think I might have missed the meaning of "shadowed variable names" |
| 00:19 | <~Vornicus> | Because I'm not really an FP guy and what I think of shadowed variable names is that they're, um. THe obvious way to go about things? |
| 00:19 | <&McMartin> | Where an inner scope has a variable that is the same name as some outer scope, and this is not an error |
| 00:20 | <&McMartin> | Though to be fair "should this be an error" and "should you ever actually do this" are two different things. |
| 00:20 | <&McMartin> | In something like C++ I'm pretty OK with "you should not do this except for this->x = x" |
| 00:21 | <&McMartin> | But for something where you're throwing inline lambdas around everywhere, the default should be "not an upvalue unless it's *obviously* an upvalue" |
| 00:28 | | Derakon[AFK] is now known as Derakon |
| 00:29 | <~Vornicus> | So basically shadowing is what happens when you do assignment to a var in a function in python without first doing global |
| 00:29 | <&McMartin> | Yes. |
| 00:29 | <~Vornicus> | Okay. |
| 00:30 | <~Vornicus> | I'm not generally a fan, then. |
| 00:30 | <&McMartin> | This is a bigger deal in languages like, um, all the FP ones where single-letter parameter names are considered good style and function definitions are heavily nested |

| 19:46 | < ToxicFrog> | pretty sure it's the same as a C one |

| 20:00 | < Tarinaky> | Isn't a long 64bits usually? |
| 20:02 | <@rms> | No |
| 20:02 | <@rms> | long long is 64bits |
| 20:02 | <@rms> | long is 32 or 16 |
| 20:02 | < Tarinaky> | How can you have a 16bit variable on a 32bit archetecture? |
| 20:02 | < Tarinaky> | *architecture |
| 20:02 | < Tarinaky> | Unless you're just throwing the high/low bits away. |
| 20:03 | | * Tarinaky thought a short was 32bits on a 32bit target and everything else was just 64bits. |
| 20:03 | <@rms> | No |
| 20:04 | <@rms> | Addresses are always a single word, but they can point to /any/ size of type. |
| 20:05 | < Tarinaky> | Yeah, but aren't the registers a fixed size? |
| 20:06 | <@rms> | Yes. |
| 20:06 | <@rms> | Variables aren't registers though. |
| 20:06 | <@rms> | Unless you declare them as such. |
| 20:13 | < Tarinaky> | Well, I got told. |
| 20:16 | < ToxicFrog> | rms: actually, on AMD64, 'short' is 16-bit, 'int' is 32-bit, and both 'long int' and 'long long int' are 64-bit. |
| 20:17 | < ToxicFrog> | You're right otherwise, though. |
| 20:29 | <@rms> | Bleh |

| 22:24 | | * TheWatcher arghs, stabs ssh until it actually starts behaving in the way its documentation says it should |
| 22:27 | <@TheWatcher> | I have ssh_config set up as |
| 22:27 | <@TheWatcher> | Host localhost |
| 22:27 | <@TheWatcher> | Port <portnumber> |
| 22:27 | <@TheWatcher> | but any attempt to `ssh localhost` fails because it's still trying to connect to 22 rather than the number I set |
| 22:29 | <@TheWatcher> | But if I set it in ~/.ssh/config it works, so it's obviously just not reading /etc/ssh/ssh_config argh |
| 22:32 | < ToxicFrog> | TheWatcher: try ssh -vvv and see if it says anything useful about ssh_config. |
| 22:33 | <@TheWatcher> | If I have ~/.ssh/config I get a "debug1: Reading configuration data /home/chris/.ssh/config", but without it, nothing. It just doesn't even seem to be looking at /etc/ssh/ssh_config |
| 22:35 | < ToxicFrog> | o.O |
| 22:35 | < ToxicFrog> | strings -n10 $(type -p ssh) | fgrep ssh_config |
| 22:36 | <@TheWatcher> | yeah, it's there |
| 22:36 | < ToxicFrog> | I've got nothing |
| 22:36 | <@TheWatcher> | It's not aliased, either, so it's not silently getting a -F added somewhere |
| 22:38 | <&jerith> | TheWatcher: Are the permissions right? |
| 22:38 | <&jerith> | ssh cares a lot about permissions. |
| 22:39 | <@TheWatcher> | ... ssh_config was 644, but /etc/ssh/ was 700 |
| 22:40 | <@TheWatcher> | I should have checked that one first, thanks jerith |
| 22:40 | < ToxicFrog> | jerith: in that case I would definitely expect some sort of message |
| 22:40 | < ToxicFrog> | Especially in maximum debug mode |
| 22:40 | < ToxicFrog> | So the fact that there isn't one may be worth a bug report! |
| 22:41 | <&jerith> | ToxicFrog: I've only ever had permission warnings about homedir config stuff, not /etc config stuff. |
| 22:41 | <&jerith> | But I do very little of the latter, so. |
| 22:41 | < ToxicFrog> | jerith: yeah, my point is that it should warn |
| 22:42 | <&jerith> | If you're not root and can't fix it, the warning's just noise. |
| 22:42 | <&jerith> | But that's what Maximum Debug is /for/. |
| 22:43 | <@rms> | Is there a tab before Port? |
| 22:44 | <@TheWatcher> | Also TF, do you have any recommendations for maildrop config documentation, because I find the official documentation is spectacularly horrible |
| 22:45 | <@TheWatcher> | rms: no, but it doesn't need one, that's only there for readability. Works fine without. |

| 22:48 | <&jerith> | rms: It's fixed now. :-) |
| 22:49 | <&jerith> | 'Twas the permissions thing. |
| 22:49 | <@rms> | Ah |
| 22:51 | < ToxicFrog> | TheWatcher: look at some example filter files - I can pastebin a sanitized version of mine if you like |
| 22:52 | <@TheWatcher> | I would be deeply grateful if you could. |
| 22:52 | < ToxicFrog> | Alright. It'll have to happen after I finish making this curry, though. |
| 22:52 | <@TheWatcher> | No worries :) |
| 22:55 | | * ToxicFrog deploys the mustard oil |
| 22:56 | < ToxicFrog> | Hmm. Looking at my .mailfilter, it's not actually as interesting as I remember, because I factored most of it out into a shell script and maildrop just reads its output to figure out where to put things |
| 22:56 | < ToxicFrog> | (specifically, it gives maildrop a set of regexes-maildir pairs, and maildrop picks the first one the message matches) |
| 22:57 | <@TheWatcher> | Still likely to be useful as a reference, if you're willing |
