This week’s BSDNow talks about the recent BSD convention in Cambridge (which I somehow did not know about until afterwards), plus lots of other talk, and a link to this entertaining terminal emulator.
Questions are this week’s accidental theme.
It’s accidental how-to week!
I’m late noting this week’s BSDNow – I’m also changing the capitalization, since BIND in this case is an acronym. No interview this week but discussion of various BSDCan 2017 reports.
Back to overflow, which sort of makes my life easier.
- BCHS: BSD, C, httpd, SQLite. Linked before, so comments on source links are where to look if you are already familiar with BHCS.
- Possible stack vulnerabilities in BSD-land.
- How to disable cores in OpenBSD?
- Nextcloud via httpd on OpenBSD. (via)
- MP-safe Networking in NetBSD. PDF, from BSDCan. (via)
- BSDCan 2017 Recap from iXSystems.
- Unix in Europe: between innovation, diffusion and heritage. October 19th, Paris, France. (via)
- The Stack Clash, via many places.
- pkgsrcCon 2017, in one week.
- PCIe adapters supporting long distance 10GB fiber? Note that this is for BSD-based, server-based routers. Follow the thread for lots of hardware talk.
- OpenBSD now has Trapsleds to make life harder for ROPers.
BSDNow 198 is now available, almost all about the just-finished BSDCan.
All over the map today.
Unrelated link of the week: I Love Butter Tarts. If you’ve never encountered a butter tart, you should. Found via the Midland Butter Tart Festival, which I am disappointed to have missed.
Slightly earlier than normal because of the magic of prerecording, BSDNow 197 is up and has an interview with Michael W. Lucas about his books. (I’m hoping for interviews from BSDCan next week.)
The next NYCBUG meeting is May 3rd, in about 48 hours. Rob Seward will be presenting on random number generators. The same announcement for this meeting also notes the upcoming pkgsrcCon, BSDCan, and EuroBSDCon.
It’s long article title week!
BSDNow 186 gets back into the convention grind after last week’s news about new roles: coverage of the recent AsiaBSDCon, and an interview of Philipp Buehler.
Much better than last week, but there wasn’t any hurricane-force winds this week – which helps.
Sepherosa Ziehau went to AsiaBSDCon 2017 and gave a talk on his work with DragonFly’s networking. He’s published a report of his trip, which comes with a link to his paper, his presentation, and pictures of who he met.
Note that the PDF and the Powerpoint slides links are different; one is the paper, one is the talk. The Powerpoint slides contain the benchmarks linked here in comments, previously.
Michael W. Lucas will be showing up tomorrow with physical copies of his books at the Grosse Pointe Library. (I’m assuming it will be both his fiction and non-fiction BSD books.) If you are near, I bet you can get a signed copy.
In what can be described as perfect timing, Sepherosa Ziehau has produced a document comparing FreeBSD, several different Linux kernels, and DragonFly, for networking. He’s presenting it in the afternoon track of Day 3 for AsiaBSDCon 2017, starting later this week.
He’s published a snippet as a PDF (via), which includes some graphs. The one place Linux outperforms DragonFly seems to be linked to the Linux version of the network card driver being able to access more hardware – so DragonFly should be comparable or better there too, once the powers-of-2 problem is solved. (This already came up in comments to a post last week.)
Those graphs are available standalone, too, which means it’s easier to see the fantastic performance for latency – see the thin blue line – that seems exclusive to DragonFly. That, if anything, is the real takeaway; that DragonFly’s model has benefits not just to plain speed but to the system’s responsiveness under load. “My CPU is maxed out cause I’m doing a lot of work but I hardly notice” is a common comment over the past few years – and now we can see that for network performance, too.
Slightly short this week, maybe because people are prepping for AsiaBSDCon? I have plenty of links for tomorrow’s Lazy Reading.
