| 03:07 | <&[R]> | Ugh... I swear, I've have more issues with my work computer running MS shit than I've had with Arch (which I left because it kept routinely fucking up horribly) |
| 03:09 | <&McMartin> | What kinds of issues does Arch run into? |
| 03:10 | <&[R]> | Cyclical dependencies between kernel and libc, and they only keep the latest version in the repo. Forget the exact issue but basically prevent me from updating my systems |
| 03:12 | <&McMartin> | That seems like a rather serious problem for something that claims to be rolling-release. |
| 03:14 | <&[R]> | Also at one point they made their package manager depend on openssl (when it actually shells out the downloads). The reason for the /hard/ openssl dependency? 15% speed increase in MD5 calculation. IE: they had working MD5 calculation code in the codebase. Openssl rolled over from 0.9.8.6 to 1.0.0, all the .so symlinks changed, API changed in a breaking way so you couldn't even make a symlink to fix it. |
| 03:14 | <&[R]> | 0.9.8g* |
| 03:14 | <&[R]> | They also didn't do the "let's shove /everything/ into /usr" rollout very well either. |
| 03:15 | <&[R]> | Basically, IMO, an endless stream of fuckups after the original dev left. |
| 03:19 | < Mahal> | <random> can you run an RPi with PoE? |
| 03:20 | <&McMartin> | EAP PoE? |
| 03:20 | <&McMartin> | Oh, Power over Ethernet? |
| 03:20 | <&McMartin> | I don't believe so. It's got one of those 3.5mm power jacks. |
| 03:21 | <&McMartin> | Er, wait, no. It's microUSB |
| 03:21 | <&McMartin> | So you can: https://www.amazon.com/dp/B01M1E3VC8/ref=asc_df_B01M1E3VC85330949/?tag=hyprod-20&creative=395033&creativeASIN=B01M1E3VC8&linkCode=df0&hvadid=198138936631&hvpos=1o1&hvnetw=g&hvrand=9008207341794277138&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031926&hvtargid=pla-412883840807 |
| 03:25 | <&McMartin> | But you can't just plug it into a network hub and go to town. |
| 03:25 | <&McMartin> | With its own ethernet port, tha tis. |
| 03:25 | <&McMartin> | (I think the Pi0 might not even *have* an ethernet port.) |
| 03:26 | <&McMartin> | [R]: Wow, that's even worse than Gentoo |
| 03:27 | <&[R]> | I broke Gentoo too |
| 03:27 | <&McMartin> | So did I |
| 03:27 | <&[R]> | Apparently I'm not supposed to "emerge portage" |
| 03:27 | <&[R]> | *shrugs* |
| 03:27 | <&McMartin> | But at least revdep-rebuild mostly worked |
| 03:28 | <&[R]> | Also holy fuck MS. A three stage update? Fuck your manditory file locking D: |

| 16:36 | <@TheWatcher> | Finding out which branch a given commit was made on in git: surprisingly hard to do reliably! |

| 17:20 | | Emmy [Emmy@Nightstar-9p7hb1.direct-adsl.nl] has joined #code |
| 17:43 | <&ToxicFrog> | Especially since the answer might be multiple branches, or "none of them" |
| 17:44 | <@TheWatcher> | Yeah |
| 17:44 | <@TheWatcher> | Especially as I'm trying to work it out for commits after fast-forward merges |
| 17:50 | <&McMartin> | Since Git hides this information, this is obviously a piece of information you should not want! |
| 17:53 | <&ToxicFrog> | In general, if you need this information ex post facto, you need a commit hook or similar that annotates the commit with it. |
| 17:54 | <&ToxicFrog> | If you're content with "what branch was this user on, if any, when they originally made the commit" without a deeper look at the graph, and it was relatively recent (in the past month, by default), the reflog may help there. |
| 17:56 | <@TheWatcher> | Basic thing is that we've got a bunch of student repositories from 2015 and 2016 that we need to annotate in various ways, and then throw through jenkins to get build metrics for (all as part of work towards a paper) |
| 17:57 | <@TheWatcher> | These're all in gitlab, which does handily record a lot of what we need... from the upgrade I did at the start of 2017. |
| 18:00 | <@TheWatcher> | So I've been doing various things inside the bare repos, like working when pushes happened using timestamps in the git object databases and detecting forced pushes |
| 18:02 | <@TheWatcher> | But we also want various other bits of data, including which branch commits happened on, and I think I'm just going to have to look at the tree objects to rebuild the graph and use that |

| 18:44 | <&ToxicFrog> | That's definitely not sufficient in the general case, since branch pointers can be created or deleted after the commit is made, and the branch names on the server may not match the ones used locally |

| 21:03 | <@TheWatcher> | I like the tweet quoted in there "over 100 exposed so far in china, russia, ukraine" while ignoring the big swathes of deep red in germany, france, spain, and the UK~ |

| 23:37 | <&[R]> | <Nomikos> this isn't about raspberry pi as much, but it's a good explain-read https://www.raspberrypi.org/blog/why-raspberry-pi-isnt-vulnerable-to-spectre-or-meltdown/ |
| 23:38 | <&McMartin> | ARM's technical writings on this stuff have been top-notch |
| 23:40 | <&McMartin> | That also said, :( of a sort at Patterson and Hennesy still being the cutting-edge primer |
| 23:41 | <&McMartin> | That book was old when I took the class that used it |
| 23:41 | <&McMartin> | And that was twenty years ago |
| 23:41 | <&McMartin> | Oops, wait, I didn't take that class |
| 23:42 | <&McMartin> | I took the prep class for it but not the class itself |
| 23:42 | <&McMartin> | Same authors, different book |
| 23:42 | <&McMartin> | (Computer Organization and Design: the Hardware/Software Interface) |
| 23:43 | <&McMartin> | Having read that article, though, I endorse that article |
| 23:47 | <&McMartin> | It isn't quite ELI5, but it's a very solid ELI14 |
| 23:48 | < Mahal> | I like this one too: https://ds9a.nl/articles/posts/spectre-meltdown/ |
| 23:48 | < Mahal> | closer to eli5 |
