| 00:05 | <&[R]> | Wasn't ARM the processor that also supported native JWM bytecode? |
| 00:06 | <&[R]> | JVM* |
| 00:09 | <@TheWatcher> | The ARM926EJ could. |
| 00:12 | <@TheWatcher> | that used Jazelle, an extension that added a binary translation layer between fetch and decode in the pipeline to convert the JVM bytecod einto ARM instructions on the fly. |
| 00:12 | <&[R]> | Ah |

| 00:14 | <@TheWatcher> | Was a bit of a damp squib, only one version of the ARM9 from 2001 had it. ThumbEE was supposed to replace it, but that's deprecated now too and the v8 (Cortex-A32 on) architectures don't have ThumbEE at all. |
| 00:30 | <&McMartin> | THUMB2 was a nice architecture for an era that had long since passed |
| 00:30 | <&McMartin> | AArch64 removes most of the wackiness and basically everything fun |
| 00:31 | <&McMartin> | Like conditional execution everywhere and barrel shifting as a side effect nearly any ALU operation, including index calculation on loads and stores |

| 02:59 | <&ToxicFrog> | I just started reading Racing the Beam and it is as good as advertise.d |
| 03:11 | <&McMartin> | Hooray |
| 03:12 | <&McMartin> | In particular because I suspect I was the one doing the advertising |
| 03:12 | <&ToxicFrog> | Yes |
| 03:12 | <&ToxicFrog> | Also this means I can confirm that koreader handles PDFs, and in particular PDF reflowing, well |
| 03:13 | <&McMartin> | There are a couple places where I think undue significance is applied to relatively basic engineering techniques, but I've gotten to tell rousing tales of similar techniques so perhaps Some Things That Should Not Have Been Forgotten Were Lost |

| 18:58 | <@abudhabi_> | OK, it turns out it wasn't the same key. |
| 18:58 | <@abudhabi_> | PGP apparently stores its key elsewhere. |
| 18:59 | <@TheWatcher> | abudhabi_: idly, deathcookie should be back up |
| 19:00 | <@abudhabi_> | TheWatcher: Thanks! Now Irony can bother us to post incessantly. |
| 19:04 | <@abudhabi_> | Hmm. Now that I have key-based auth up, do I need to do anything like disabling password-based auth? Or is that automagically done somehow? |
| 19:05 | <@abudhabi_> | I wouldn't want to lock myself out of the damn thing. |
| 19:06 | <@TheWatcher> | in your sshd_config, set PasswordAuthentication no and restart. Then try connecting another ssh session to see if it works. restarting sshd shouldn't disconnect your existing session |
| 19:08 | <@TheWatcher> | (you need to explicitly set it to 'no', not just comment out any 'PasswordAuthentication yes' as 'yes' is the default) |
| 19:10 | <@abudhabi_> | TheWatcher: What I'm trying to prevent here is losing the key somehow, and being henceforth locked out of connecting to the box, which sits in Hong Kong. |
| 19:11 | <@abudhabi_> | If need be, I want password-auth to be available. |
| 19:12 | <@TheWatcher> | Oh, right. Well, you can use multiple keys - so you could have keys on several machines? |
| 19:12 | <@TheWatcher> | Just add their public parts to your authorized_keys and then you can get there from any of them |
| 19:13 | <@abudhabi_> | Can I just set it to have a time-out period for every failed authentication? |
| 19:13 | <@TheWatcher> | Alternatively, if you really want to keep password auth as an option, and you have a static IP you can connect from: |
| 19:14 | <@TheWatcher> | PasswordAuthentication no |
| 19:14 | <@TheWatcher> | Match address x.x.x.x |
| 19:14 | <@TheWatcher> | PasswordAuthentication yes |
| 19:14 | <@TheWatcher> | That'll block password logins except from that IP |
| 19:15 | <@abudhabi_> | Dynamic IP here, unfortunately. Though I might see if any of the shells I have are on static IPs. |
| 19:16 | <@TheWatcher> | Also, look at fail2ban. That's a program that can be set to scan your logs for failures (or other sorts of behaviour) and uses iptables rules to block troublecausers. |
| 19:17 | <@abudhabi_> | How much config does that need? |
| 19:17 | <@TheWatcher> | For straight-up sshd, on the standard port, almost none. |
| 19:17 | <@abudhabi_> | Just aptitude install, then? |
| 19:19 | <@TheWatcher> | plus one config file /etc/fail2ban/jail.local containing the rules you want to turn on, an example: http://pastebin.starforge.co.uk/18 |
| 19:19 | <&[R]> | abudhabi_: Are you trying to use a PGP key as an SSH key? |
| 19:20 | <&[R]> | Because they're different things |
| 19:21 | <@abudhabi_> | [R]: I wouldn't know. Key-based stuff is black magic to me. It's an interface that is even less human-friendly than passwords. |
| 19:21 | <@abudhabi_> | TheWatcher: You mean jail.conf? |
| 19:22 | <@TheWatcher> | nope |
| 19:22 | <@abudhabi_> | I should create jail.local, then? |
| 19:22 | <@TheWatcher> | Yep, fail2ban uses .local files as the things to create your own local config |
| 19:23 | <@abudhabi_> | OK, cool. Thank you! |
| 19:24 | <@abudhabi_> | Now I feel adequately secure from Chinese hackers! :V |

| 19:33 | <@abudhabi_> | Hmm. If I have working HTTPS via certbot, that's evidence of working Lets Encrypt SSL certs, right? |
| 19:33 | <@abudhabi_> | Regarding https://community.letsencrypt.org/t/simple-guide-using-lets-encrypt-ssl-certs-with-dovecot/2921 |
| 19:34 | <@TheWatcher> | Yep. |
| 19:35 | <@TheWatcher> | If you're serving pages through apache over https and your browser is showing the certs are valid, you're good |

| 21:39 | <&McMartin> | .... holy shit |
| 21:40 | <&McMartin> | Given how terrible the user experience is on Unix for CMake, in grimly Unixy ways... |
| 21:40 | <&McMartin> | ... its Windows integration is top notch |
| 21:41 | < Emmy> | odd |
| 21:42 | < Emmy> | on a sad note, today i heard my project of the past years is going to stop |
| 21:42 | <&McMartin> | It presents a GUI that preconfigures its own sandbox to work in, you can interatively run the configure script and edit or create new env vars as needed, and then the generators for Visual Studio or MSYS2 appear to Just Work. |
| 21:43 | <&McMartin> | I suppose in a way this is less surprising. "Proper Windows Integration" assumes you've brought all your dependencies in pre-packaged, by default |
| 21:43 | <&McMartin> | While CMake on Unix is all about dodgy autodetect scripts that usually end up hijacking in hard dependencies to quirks of your specific distro. |
| 21:43 | <&McMartin> | "Oh, were you hoping to build a binary somebody else could run?" |
| 21:44 | <&McMartin> | "Who the fuck does that" |
| 21:45 | < simon_> | Emmy, what's the project? |
| 21:49 | < Emmy> | an access application pack of three programs we supported/maintained and developed |
| 21:50 | < Emmy> | had me working the full 18h per week recently |
