| 01:09 | <&ToxicFrog> | Hahahahahaha holy fuck what |
| 01:09 | <&ToxicFrog> | On windows: |
| 01:10 | <&ToxicFrog> | strftime("%Y-%m-%d") -> "2014-11-25" |
| 01:10 | <&ToxicFrog> | strftime("%F") -> segfault |
| 01:24 | <&Derakon> | What's %F? %f is apparently microsecond time. |
| 01:26 | <@Azash> | http://strftime.org/ |
| 01:27 | <&McMartin> | This kind of shit is why I keep Windows and POSIX implementations separated. -_- |
| 01:28 | <@Azash> | Oops, I don't know why I assumed python |
| 01:29 | <@Azash> | Anyway Windows doesn't have %f or %F according to this MSDN article |
| 01:29 | <~Vornicus> | The real WTF is that you can segfault a program with a bad format string |
| 01:29 | <@Azash> | Vornicus: Isn't this part of the Windows API vision |
| 01:30 | <&McMartin> | You think that's unique to Windows~ |
| 01:32 | <~Vornicus> | This doesn't make it less WTF~ |
| 01:33 | <&McMartin> | Yeah |
| 01:33 | <&McMartin> | But I mean |
| 01:33 | <&McMartin> | If you support printf, you can introduce arbitrary-code-execution security holes with a bad format string |
| 01:33 | <&McMartin> | That is the case that made me long for a --suppress-bullshit compilation flag |
| 01:35 | <&ToxicFrog> | Azash: windows not supporting %F doesn't surprise me, no. |
| 01:35 | <&ToxicFrog> | The segfault does, though. |

| 04:28 | <@Azash> | Since AJ isn't here to post it himself |
| 04:34 | <&Derakon> | Uber is quite blatantly evil. |
| 04:35 | <&Derakon> | They're only getting away with it because the taxi industry isn't always exactly saintly itself. |
| 04:35 | <@Azash> | They're getting away with it because customers don't care and the drivers are too locked in to bail |

| 08:44 | <&McMartin> | It uses the internet to pretend that laws regulating taxis don't apply to them |
| 08:45 | <&McMartin> | I'm being slightly snarky but this is seriously basically the plan. They use random internet people to be as-needed taxis and file lawsuits against cities who try to stop them |
| 08:46 | <@Azash> | They also treat the drivers like shit in addition to the privacy issues with their app |
| 08:49 | <@Julius> | Interesting idea, in principle. Pity about the evil, though. |
| 09:05 | | * Julius reads the wiki page. |
| 09:06 | <@Julius> | WTF. They apparently have higher prices than taxis. Why would you sign up for that? |

| 09:53 | <@TheWatcher> | Julius: never underestimate the gullability of the public, or the appeal of convenience |
| 10:00 | <@TheWatcher> | Why have to walk to a taxi rank, wait to hail a taxi, or have to fine a phone number to call, when you can "Press button, summon taxi" and track where it is? The fact that it's not cheaper is irrelivant if you don't know taxi fare structures (which, realistically, can be somewhat byzantine), or will trade off the price for convenience. And as far as the privacy issues, people have a woefully ignorant, lackadaisical, or outright ostritch-like |
| 10:00 | <@TheWatcher> | approach to the permissions apps request and their privacy in general |
| 10:02 | <@TheWatcher> | (not that the app writers, or the permissions warnings, help with this - some needelessly requesting permissions they don't really need, producing 'permission review fatigue' amongst even the ones that don't just blindly hit "accept", while the overly-broad scope of some permissions and the lack of explanation about why permissions are requested makes evaluation difficult or event futile) |
| 10:03 | <@Azash> | I'm just happy it's exceedingly difficult to allow the BRICK permission |

| 11:46 | <@Tarinaky> | Argh, does anyone have a guide to the format of usage strings for command line utilities? |
| 11:46 | <@Tarinaky> | I need to look up some obscura. |
| 11:47 | <@Tarinaky> | I have a command which accepts one of two strings, so I want to render the usage as A|B |
| 11:47 | <@Tarinaky> | But I'm not sure what kind of brackets I need, or if I need brackets. |
| 11:47 | <@Tarinaky> | Since the strings are constant, not variable. |
| 11:51 | <@TheWatcher> | There is no formal spec, the closest you'll get is the SYNOPSIS description in man 7 man-pages |
| 11:51 | <@TheWatcher> | which is really something like 2 sentences |
| 11:54 | <@Julius> | Inner join to the rescue! |
| 11:59 | <@Julius> | (SELECT B.prop, COUNT(C.whatevs) FROM B INNER JOIN C on B.Id = C.BId WHERE B.AId = 1 GROUP BY B.prop;) |
| 12:00 | <@Tarinaky> | TheWatcher: "Oh" |

| 12:04 | <@Julius> | He never says that. |
| 12:04 | <@Tarinaky> | The audience do |
| 12:15 | | * TheWatcher hairpulls at CSS::Inliner |
| 12:23 | <@Julius> | A left join works even better. |
| 12:24 | <@Julius> | I never understood how joins worked during studies. |
| 12:25 | <@TheWatcher> | Let me guess; they went on at length about relational algebra, with only cursory coverage of how it works in reality? |
| 12:27 | <@Julius> | Yeah. |
| 12:28 | <@Julius> | You're some kind of teacher, right? |
| 12:29 | <@TheWatcher> | Some kind of, yes; I teach a C Programming intro course. |
| 12:31 | <@TheWatcher> | Mostly to MSc conversion students and single-module externals |
| 12:31 | <@TheWatcher> | (public, industry - mostly aerospace and automotive) |
| 12:32 | <@Julius> | The only time I needed joins was during Linq courses. And then I brute-forced the issue by editing my query until I got results I wanted. |
| 12:35 | <@froztbyte> | Tarinaky: foo -a --asd -bar <baz> [-d xyz [xyzzy ...]] |
| 12:36 | <@froztbyte> | for mandatory, option with mandatory parameter, optional, and optional with repeat |
| 12:36 | <@froztbyte> | foo -a --asd [-bar baz|-d xyz] |
| 12:37 | <@froztbyte> | (and I should note that "-bar" is then often 3 parameters, often overriding the earlier -a) |
| 12:37 | <@froztbyte> | beyond that it gets pretty situational, such as what you're using to parse the options, etc |
| 12:38 | <@froztbyte> | if you use python's argparse, you can mark things as optional or n-many args (nargs) and it'll DTRT |
| 12:38 | <@froztbyte> | etc etc per language or library |
| 12:38 | <@froztbyte> | gnu find has everything prefixed with single hyphens, for instance |
| 13:02 | <@Tarinaky> | froztbyte: Technically this isn't a CLI utility. I'm just trying to borrow the conventions to be familiar |
| 13:02 | | * Julius glares at Java. |
| 13:02 | <@Julius> | I had to cast an int to an Integer. |
| 13:03 | <@Tamber> | Tarinaky, well, depending on which convention you want to follow... (-h, -?, -help, --help ;_;) |
| 13:03 | <@Tarinaky> | Julius: That's because they're different things. |
| 13:03 | <@Tarinaky> | Julius: int is a primative type |
| 13:03 | <@Julius> | I know this. |
| 13:03 | <@Tarinaky> | Julius: Integer is an object encapsulating an int |
| 13:04 | <@Tarinaky> | I forget exactly which of the two is mutable. |
| 13:11 | <@Julius> | Can I sort a Java Map somehow? c:forEach is displaying the key/value pairs in strange order. |
| 13:12 | <@Tarinaky> | Use a different type of map |
| 13:13 | <@Tarinaky> | http://docs.oracle.com/javase/6/docs/api/java/util/TreeMap.html |
| 13:13 | <@Tarinaky> | The default Map is going to be a HashMap - so the ordering is according to the key's hash value. |
| 13:14 | <@Julius> | Thanks! |
| 13:15 | <@Julius> | This ALMOST worked. |
| 13:15 | <@Julius> | The key is a String. Therefore "10" goes before "2". |
| 13:16 | <@Julius> | I guess I could change it to an Int,Int map, although that would probably cause problems later. |
| 13:16 | <@Tarinaky> | Does the key need to be a string? |
| 13:16 | <@Tarinaky> | The alternative is to specialise a string class with new comparison operators that parses numerical data as a 'special case' |
| 13:17 | <@Julius> | It sort of does. A planned future feature is to include more than just numeric options. |
| 13:18 | <@Tarinaky> | Oh! |
| 13:18 | <@Tarinaky> | Do you need to mix-and-match string and int data? |
| 13:19 | <@Tarinaky> | Is "String 10" < "String 2" ? |
| 13:19 | <@Julius> | The key could be any string (but probably one-word). |
| 13:19 | <@Julius> | What? |
| 13:19 | <@Tarinaky> | Is that a feature you require. |
| 13:20 | <@Tarinaky> | One thing you could do is parse the string for integers and string-reverse them |
| 13:20 | <@Julius> | That is a feature that is not required now, but will be required later. I guess I'll make the map int,int for the moment, and worry about this later. |
| 13:20 | <@Tarinaky> | No, wait, that won't work, you'd need padding as well |
| 13:20 | <@Tarinaky> | Hmm... |
| 13:21 | <@Tarinaky> | Julius: I think the simplest solution is probably going to be to have an object containing two Maps |
| 13:21 | <@Tarinaky> | And then you can concatenate the <string,int> map onto the end of the <int,int> map maybe? |
| 13:22 | | * Tarinaky is brainstorming |
| 13:22 | | * Julius changes it to TreeMap<Integer,Integer> which works. |

| 15:45 | <@Julius> | Tarinaky: English names are silly. |
| 15:45 | <@Tarinaky> | Julius: What the fuck is an 'English' name? |
| 15:46 | <@Julius> | Slavic names are very sensible about ending every female name with -a and almost even proper male name with a consonant. |

| 15:46 | <@Julius> | Tarinaky: Names used in the Anglosphere, of course. You might refer to them as 'the Colonies' and such. :P |
| 15:46 | <@Tarinaky> | English as a language is cobled together from more interesting parts of the world and slightly dumbed down the better to bodge it together. |
| 15:47 | <@Tarinaky> | 'English names', likewise, are a bodge of mispelled Saxon, Celtic, Norman etc... |
| 15:47 | <@Julius> | Yeah, that's much of the problem. |
