Lazy Reading for 2018/09/16

Unofficial history theme this week – but not UNIX-specific, for once.

Your unrelated baking video of the week: Round Cake Production with Unifiller Depositors and Decorating Equipment.  I’m not recommending this as a food; it’s just somewhat hypnotic to watch the robot production of something you usually imagine as lovingly handcrafted.

Unofficial accidental “time” theme this week.  Also charts!

Some package statistics

The article I linked yesterday about Ravenports got me wondering about what package are most popular.  avalon.dragonflybsd.org is the default binary package archive for pkg, and it has httpd logs back to 2013, so I collated some information.

I read out a list of packages, and weighed them according to how recently they were downloaded.  I also mushed together all the py/ruby/p5/php numbered packages, and excluded lib*.

After all that… there’s a lot of noise.  One install of any desktop environment pulls in hundreds of packages automatically, so it’s hard to tell what’s installed by a human and what’s installed by dependency.  That being said, here’s some highlights.  This is me applying an arbitrary value and then arbitrarily snipping out a list… but it’s fun to see if nothing else.

New mechanism: kcollect

There’s a new facility in DragonFly: kcollect(8).  It holds automatically-collected kernel data for about the last day, and can output to gnuplot.  Note the automatic collection part; your system will always be able to tell you about weirdness – assuming that weirdness extends to one of the features kcollect tracks.  Here’s some of the commits.

In Other BSDs for 2017/07/22

It’s accidental how-to week!

AsiaBSDCon 2017 and DragonFly networking

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.

Network performance comparison

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.

I had too many links for this as early as Tuesday.

Your unrelated video link of the week: Rotoscoped Horse.  Taken from the old Muybridge photos.  (via)

I am proud of finding some of these links this week; they are not the usual “here’s what everyone else linked to” that you see.

Your unrelated graph link of the week: Visualizing HipHop trends from 1989 – 2015.  (via)

Lazy Reading for 2014/09/14

I didn’t even notice, because this has been a difficult week for me, but I’ve hit over 6,000 posts on the Digest. I passed the 11-year mark too, a few weeks ago.

Your unrelated video of the week: Tea Making Tips, from England in 1941.  This 60-year-old WW2-era film is actually one of the better how-to-deal-with-tea guides I’ve ever seen. (via)
