| 02:01 | <&ToxicFrog> | wait, patch runs ed? wtf |
| 02:01 | <&[R]> | Not the OpenBSD one |
| 02:01 | <&[R]> | Anymore anyways |
| 02:02 | <&McMartin> | I'm starting to think that one disadvantage of the "collection of very general small sharp tools" philosophy is that these tools are then used. |
| 02:02 | <&[R]> | lol |
| 02:02 | <&[R]> | IMO it's better than the alternatives |
| 02:03 | <&McMartin> | Which, to make it less sarcastic sounding - a direct consequence of that is that all tools end up more general than one would actually like them to be. |
| 02:03 | <&[R]> | Since you can replace a tool on a tool by tool bassis |
| 02:03 | <&McMartin> | Yeah. The problem here is not "small" or "sharp" but "very general". |
| 02:03 | <&[R]> | In that they always have more capability than you expect them to? |
| 02:03 | <&McMartin> | Well, hm |
| 02:04 | <&McMartin> | There isn't any power there that I wouldn't expect from ed |
| 02:04 | <&McMartin> | But because patch is implemented in terms of ed, that means that now patch has power I wouldn't expect |
| 02:04 | <&McMartin> | and "this innocuous-looking thing has power I wouldn't expect" is entirely too many vulnerabilities. |
| 02:04 | | * Alek snickers. |
| 02:04 | <&[R]> | Ah |
| 02:05 | <&McMartin> | Including at minumum all XSS, code injection, and format string vulnerabilities |
| 02:05 | <&McMartin> | minimum, even |
| 02:05 | <&[R]> | Then if you use say bc in a script to calculate something, you might not realize that bc can do loops and print strings. |
| 02:05 | <&[R]> | As an example |
| 02:05 | <&McMartin> | And so you might pass user input into it. |
| 02:05 | <&[R]> | Yeah |
| 02:06 | <&McMartin> | Or, for the format string vuln: a lot of people didn't realize that printf's spec included writing arbitrary memory |
| 02:06 | <&[R]> | Yup |
| 02:07 | <&[R]> | Hmm. I wonder if PHP's printf actually passes stuff to vsprintf. |
| 02:07 | <&McMartin> | I was going for the cheap laugh in the initial phrasing, but there's a serious point there too. |

| 04:39 | <&McMartin> | Apparently actually updating the screen properly will take more than one frame. |
| 04:39 | <&McMartin> | I think I have room to double-buffer it but it'll be inconvenient. |
| 04:41 | <&McMartin> | Even with BLAST PROCESSING it can only blit 12KB a frame. Not quite that, even. |

| 12:26 | <&ToxicFrog> | [R]: how big, and what kind of uptime, performance, and load requirements do you have? |
| 12:27 | <&ToxicFrog> | The three options that come immediately to mind are self-hosting, running nginx on the GCP free tier (which gives you an itty bitty VM and 30GB of storage), or (if you have no deletion requirements) shoving it into IPFS and pointing at one of the public IPFS gateways |

| 15:54 | <&ToxicFrog> | Aah |
| 15:57 | <~Vornicus> | But in order to do it he has to manage to get to exactly 0 horizontal distance, avoid getting knocked out of the hitbox by being near oob, and then actually get knocked back. https://www.youtube.com/watch?v=8jd3A2euOjg |

| 19:13 | <&McMartin> | I just noticed something that it's unusual it's taken me this long to notice. |
| 19:13 | <&McMartin> | I've been repeatedly burned by people who pay attention to Unix tools that talk about converting text files to "Mac format" despite the fact that Macs have not used "Mac" format for over 17 years |
| 19:13 | <&McMartin> | But it's not just that; \r\n to those tools is "DOS format". |
| 19:14 | <&McMartin> | These markers haven't changed since 1994 at the absolute latest. |
| 19:20 | <&ToxicFrog> | The tool names `dos2unix` and `mac2unix` may not be accurate any more but an awful lot of scripts will break if they change to `crlf2lf` and `cr2lf` :P |
| 19:20 | <&ToxicFrog> | (also I would argue that CRLF is "DOS format", it's just that windows also uses it) |
| 19:20 | <&McMartin> | I'm really more referring to the menu options in interactive programs. |
| 19:20 | <&McMartin> | In fact, having just checked |
| 19:21 | <&[R]> | ToxicFrog: Wasn't for me. A non-technical person wanted to do a mock-up update to their company's website (as the current layout is causing confusion with their users). |
| 19:21 | <&McMartin> | macOS's own version of nano will let you convert to what it calls "Mac format" and which your Mac will dislike intensely if you do |
| 19:21 | <&ToxicFrog> | MacOS, or OSX? |
| 19:22 | <&ToxicFrog> | If the former, I didn't realize there was a build of nano for it. |
| 19:22 | <&McMartin> | OSX becames macOS with 10.12. |
| 19:22 | <&ToxicFrog> | Aah. |
| 19:22 | <&ToxicFrog> | How confusing. |
| 19:22 | <&McMartin> | Mac OS note space and capital M in fact did use bare \r, like all home computers of the 1984 era |
| 19:23 | <&McMartin> | However, Mac OS has not been what runs on Macs for over 17 years |
| 19:24 | <&McMartin> | Also, while I don't have a Windows machine handy ISTR that Notepad++ also names \n and \r "UNIX" and "Mac", but I think it calls crlf "CRLF". |
| 19:25 | <&ToxicFrog> | Ideally here I think the answer would be "LF", "CR", and "CRLF", since as a rule anyone who cares about line ending format will know what those mean |
| 19:25 | <&McMartin> | Yeah, and I'm pretty sure that NP++ actually has that but also puts in parenthetical comments |
| 19:28 | <&ToxicFrog> | tfw the tests suddenly start passing |
| 19:31 | | * McMartin ponders |
| 19:31 | <&McMartin> | Is it a good feeling or a bad feeling? |
| 19:32 | <&ToxicFrog> | I wasn't expecting them to start passing, so it's a what-have-I-missed feeling. |

| 23:04 | <&McMartin> | Yikes, my surge protector gave me a loud spark when I tried to plug my laptop into it |
| 23:04 | <&McMartin> | I think I'll go plug it in somewhere else. |
| 23:04 | <&McMartin> | Nothing appears to be on fire, at least. |
| 23:07 | < Degi> | My outlets spark blue when I put my laptop charger in... |
| 23:07 | < Degi> | I think the capacitor is directly connected to the rectifier. |
| 23:07 | <&McMartin> | I think it was the loudness that made me unhappy about this. |
| 23:07 | < Degi> | Ye mine makes a tiny bang-like sound when I plug it in |
| 23:11 | <@gnolam> | Transformers. |
| 23:11 | <@Alek> | Robots in disguise! |
| 23:11 | <&McMartin> | Be that as it may, it seems the other surge protectors like this charger more. |
| 23:12 | <&McMartin> | So I'll leave it over there |
| 23:12 | <&McMartin> | "It may be an indictment of Clojure's friendliness to beginners, or it might be that Clojure is the language for cranky, old, tired developers" |
| 23:13 | <&McMartin> | *huge burst of applause* |
| 23:13 | <&ToxicFrog> | \whynotboth |
| 23:13 | <&ToxicFrog> | As much as I like Clojure it really isn't friendly to beginners |

| 23:27 | <&McMartin> | That's from this talk: https://www.youtube.com/watch?v=2V1FtfBDsLU |
| 23:33 | <@gnolam> | (Computer power supplies are just fancy transformers. Transformers work through induction. Induced current is proportional to di/dt. Breaking or closing a circuit means di/dt -> ∞/-∞. Thus: sparks.) |
| 23:34 | <@gnolam> | *voltage |
| 23:34 | <&McMartin> | Yeah. Which in turn means "that plug or that socket was a bit misshapen and wouldn't maintain a clean contact on the way in" |
| 23:40 | < Degi> | Well, they got like an input capacitor which sometimes makes a bang unless they got a surge current limiter (that's why my 3 kW PSU never flipped the breaker, whereas a small 150 W PSU did). |
