Module name:	src
Changes by:	2023/09/18 07:16:13

Modified files:

Log message:
crank to 7.4-beta

Snapshots are (already) available for several platforms. At the time of writing, there are a mixture of 7.3 and 7.4 files on at least some mirrors, so readers are advised that problems may occur.

(Regular readers will know what comes next…)

This serves as an excellent reminder to upgrade snapshots frequently, test both base and ports, and report problems [plus, of course, donate!].

p2k23 Hackathon Report: Volker Schlecht (volker@) on rust and erlang progress

Contributed by rueda on from the brushing up the rust dept.

We are pleased to have another p2k23 report, this time from Volker Schlecht (volker@) who writes:

"Ladies and Gentlemen, our plane is equipped with two engines, and I'm afraid I need to tell you that the one that you see to your right won't start right now…"
As with several other developers my trip to p2k23 didn't exactly start off as planned. Eventually the engine did start, though (and I'm glad to report it stayed on, too) and I made it to Dublin.

3D printing on OpenBSD? Yes, that’s a thing!

Contributed by Ian Darwin on from the 'What else can you do with it?' dept.

Can you really do 3D printing from OpenBSD? Cue suspenseful music whilst I formulate my answer, which is: Yes.

If you aren’t familiar with the 3D printing process, it’s divided into several steps, vaguely analogous to writing, compiling and running a program in a compiled language.

p2k23 Hackathon Report: Landry Breuil (landry@) on chasing memory corruptions

Contributed by rueda on from the birds do thunder dept.

Next up in the series of p2k23 hackathon reports is this from Landry Breuil (landry@), who writes,

It's been a while since the last p2k19 in bucarest… and this time in a new place, city, country, lovely ireland with a lovely weather at this time of the year.

As usual, i wanted to play with things that were left on the side for a while (upgrading mail/stalwart stack to the new all-bundled-in-one layout to play with JMAP… or testing matthieu@'s work on wayland) - but i was of course mostly distracted from those interesting topics by …firefox, you guess it. Dammit, not again !

p2k23 Hackathon Report: Jeremy Evans (jeremy@) on Ruby ports cleanup, database progress, and more

Contributed by rueda on from the ruby red, turning green dept.

Next up in our reports from the p2k23 hackathon is one from Jeremy Evans (jeremy@). Jeremy writes:

My travel to Dublin started off not so great, with the airline figuring out they had to replace the copilot's chair in the cockpit after everyone had boarded, forcing everyone to deplane and then reboard an hour later. I ended up getting to Dublin a couple hours later than scheduled. This was the day before the hackathon started, so thankfully I didn't miss any hacking time. After I arrived, I took a brief nap, then found out where the hackroom was.

p2k23 Hackathon Report: Marc Espie (espie@) on a flurry of packages activity

Contributed by Peter N. M. Hansteen on from the stoutended puffy dept.

The p2k23 OpenBSD packages hackathon just concluded, and Marc Espie (espie@) wrote in with this report:

Off to Dublin, or almost.

This ports hackathon started with a reminder that real-life bugs do matter: my morning flight was cancelled and I arrived in Dublin late that day.

Turns out that air traffic uses named waypoints, which are supposed to be unique, but there's no central name registry, and two local waypoints ended up with the same name, which caused huge confusion in air traffic to Ireland: planes making large detours. As it turns out, there ARE some safety regulations, so crews can't fly forever, and Aer Lingus had to cancel my flight: no idea whether the plane didn't make it to Paris, or if the crew logged so many hours that they couldn't fly back.
(all of this info courtesy of sthen@ and mlarkin@, one being the thorough guy who always finds out the most obscure details, and the other one having actual flying experience)
