Petter Reinholdtsen: Playing and encoding AV1 in Debian Bullseye
April 16, 2022, 6:40 AM
Inspired by the recent news of
hardware encoding support from Intel, I decided to look into
the state of AV1 on Linux today. AV1 is a
and open standard as defined by Digistan without any royalty
payment requirement, unlike its much used competitor encoding
H.264. While looking, I came across an 5 year
question on askubuntu.com which in turn inspired me to check out
how things are in Debian Stable regarding AV1. The test file listed
in the question (askubuntu_test_aom.mp4) did not...

Jonathan Dowland: hledger
April 14, 2022, 9:07 AM
This year I've decided to bite the bullet and properly try out
hledger for personal accounting. It seems I need to
commit to it properly if I'm to figure out whether it will work for me or not.
Up until now I'd been strictly separating my finances into two buckets: family
and personal. I'd been using GNUCash for a couple of years for my personal
finances, initially to evaluate it for use for the family,
but I had not managed to adopt it for that.
I set up a new git repository to track the ledg...

Dirk Eddelbuettel: drat 0.2.3 on CRAN: Arm M1 Support
April 14, 2022, 1:16 AM
A new minor release of drat arrived on CRAN today. drat stands for drat R Archive Template, and helps with easy-to-create and easy-to-use repositories for R packages. Since its inception in early 2015 it has found widespread adoption among R users because repositories with marked releases is the better way to distribute code. See below for a few custom reference examples.
Because for once it really is as your mother told you: Friends don’t let friends install random git commit snapshots. Prope...
Antoine Beaupré: Tuning my wifi radios
April 13, 2022, 8:56 PM
After listening to an episode of the 2.5 admins podcast, I
realized there was some sort of low-hanging fruit I could pick to
better tune my WiFi at home. You see, I'm kind of a fraud in WiFi: I
only started a WiFi mesh in Montreal (now defunct), I don't
really know how any of that stuff works. So I was surprised to hear
one of the podcast host say "it's all about airtime" and "you want to
reduce the power on your access points" (APs). It seemed like sound
advice: better bandwidth means less time...
Jonathan Dowland: Another Green World
April 13, 2022, 8:41 AM
Brian Eno's classic 1975 album Another Green World, with the
iconic cover crop from Tom Philip's After Raphael. This is a
recent pressing. I try to avoid buying new vinyl, and I think I
got this as part of a trade-in swap two years ago when I went to
get one of my first Covid vaccinations in Newcastle. It was the
first time I'd been anywhere near a record shop (which was adjacent
to the temporary vaccine centre) in a year or more, and I took the
opportunity to bring in some records to sell. I de...
Sven Hoexter: Emulating Raspi2 like hardware with RaspiOS in 2022

Paul Tagliamonte: k3xec.com/patty: Go bindings to patty
April 11, 2022, 11:33 PM
AX.25 is a tough protocol to use on UNIX systems. A lot of the support in
Linux, specifically, is pretty hard to use, and tends to be built into the
reptilian brain of the kernel. xan built a userland
AX.25 stack called patty, for which I have
now built some Go bindings on top of.
Code needed to create AX.25 Sockets via Go can be found at
and imported by Go source as
Clint patty programs (including consumers of this Go library) work by
Jonathan Dowland: With Teeth
April 11, 2022, 8:53 AM
Sometimes people ask me which is the best entry point for Nine Inch Nails,
and I have trouble answering. I've eventually decided that it's 2005's With
I've pulled this from my pile of records to sell. Most Nine Inch Nails stuff
seems to increase in value over time, and it's got to the stage that some of
the ones in my collection are now valuable enough that I'm nervous to play them,
which makes them a little pointless. A couple of years ago, a handful of the
albums were re-issued...
Dirk Eddelbuettel: RcppRedis 0.2.1: Maintenance
April 10, 2022, 2:02 PM
A month after the major release 0.2.0 bringing pub/sub and other goodies to our RcppRedis package, a new version 0.2.1 arrived on CRAN yesterday. RcppRedis is one of several packages connecting R to the fabulous Redis in-memory datastructure store (and much more). RcppRedis does not pretend to be feature complete, but it may do some things faster than the other interfaces, and also offers an optional coupling with MessagePack binary (de)serialization via RcppMsgPack. The package has carried prod...
Dirk Eddelbuettel: RcppEigen 0.3.3.9.2 on CRAN: Maintenance
April 8, 2022, 11:31 PM
A new release 0.3.3.9.2 of RcppEigen arrived on CRAN today (and already went to Debian). Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
This update was (as it happens) requested by CRAN as R aims to bring the Fortran / C interface to best practices. We call dgesdd twice in one example and use a character argument, and the-powers-that-be now prefer better control over that character argument. So we did. Another change, kindly cont...
