Jonathan McDowell: Building a desktop to improve my work/life balance
December 2, 2021, 8:00 PM
It’s been over 20 months since the first COVID lockdown kicked in here in Northern Ireland and I started working from home. Even when the strict lockdown was lifted the advice here has continued to be “If you can work from home you should work from home”. I’ve been into the office here and there (for new starts given you need to hand over a laptop and sort out some login details it’s generally easier to do so in person, and I’ve had a couple of whiteboard sessions that needed the hig...
Paul Tagliamonte: Processing IQ data formats (Part 1/5) 🐀
December 2, 2021, 5:00 PM
🐀 This post is part of a series called "PACKRAT". If this is the first post
you've found, it'd be worth reading the
intro post first and then looking over
all posts in the series.
When working with SDRs, information about the signals your radio is receiving
are communicated by streams of
data. IQ is short for “In-phase” and “Quadrature”, which means 90 degrees
out of phase. Values in the IQ stream are commonly treated as
complex numbers because it
helps greatly when processing the...
Paul Tagliamonte: Intro to PACKRAT (Part 0/5) 🐀
December 2, 2021, 4:00 PM
Hello! Welcome. I’m so thrilled you’re here.
Some of you may know this (as I’ve written about in the past), but if you’re
new to my RF travels, I’ve spent nights and weekends over the last two years
doing some self directed learning on how radios work. I’ve gone from a very
basic understanding of wireless communications, all the way through the process
of learning about and implementing a set of libraries to modulate and
demodulate data using my now formidable stash of
SDRs. I’ve b...
Steve Kemp: It has been some time..
December 2, 2021, 3:00 PM
I realize it has been quite some time since I last made a blog-post, so I guess the short version is "I'm still alive", or as Granny Weatherwax would have said:
Of course if I die now this would be an awkward post!
I can't think of anything terribly interesting I've been doing recently, mostly being settled in my new flat and tinkering away with things.  The latest "new" code was something for controlling mpd via a web-browser:

Dirk Eddelbuettel: drat 0.2.2 on CRAN: Package Maintenance
December 2, 2021, 1:33 PM
A fresh and new minor release of drat arrived on CRAN overnight. This is another small update relative to the 0.2.0 release in April followed by a 0.2.1 update in July. This release follows the changes made in digest yesterday. We removed the YAML file (and badge) for the disgraced former continuous integration service we shall not name (yet that we all used to use). And we converted the vignette from using the minidown package to the (fairly new) simplermarkdown package which is so much more ap...

Dirk Eddelbuettel: digest 0.6.29 on CRAN: Package Maintenance
December 1, 2021, 12:31 PM
Release 0.6.29 of the digest package arrived at CRAN earlier today, and will be uploaded Debian shortly.
digest creates hash digests of arbitrary R objects (using the md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64, murmur32, spookyhash, and blake3 algorithms) permitting easy comparison of R language objects. It is a mature and widely-used as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation.
This release only contains two smal...

Russell Coker: Links November 2021
November 30, 2021, 1:31 PM
The Guardian has an amusing article by Sophie Elmhirst about Libertarians buying a cruise ship to make a “seasteading” project off the coast of Panama [1]. It turns out that you need permits etc to do this and maintaining a ship is expensive. Also you wouldn’t want to mine cryptocurrency in a ship cabin as most cabins are small and don’t have enough airconditioning to remain pleasant if you dump 1kW or more into the air.
NPR has an interesting article about the reaction of the NRA to the...
Steinar H. Gunderson: Commitcoin
November 30, 2021, 11:00 AM
How do you get a git commit with an interesting commit ID (or “SHA”)?
Of course, interesting is in the eye of the beholder, but let's define
it as having many repeated hex nibbles, e.g. “000” in the commit would
be somewhat interesting and “8888888888888888888888888” would be very
interesting. This is pretty similar to the dreaded cryptocoin mining;
we have no simple way of forcing a given SHA-1 hash unless someone
manages a complete second-preimage break, so we must brute-force.
Russell Coker: Your Device Has Been Improved
November 30, 2021, 9:41 AM
I’ve just started a Samsung tablet downloading a 770MB update, the description says:
Overall stability of your device has been improved
The security of your device has been improved
Technically I have no doubt that both those claims are true and accurate. But according to common understanding of the English language I think they are both misleading.
By “stability improved” they mean “fixed some bugs that made it unstable” and no technical person would imagine that after a certain n...
Evgeni Golov: Getting access to somebody else's Ansible Galaxy namespace
November 29, 2021, 8:00 AM
TL;DR: adding features after the fact is hard, normalizing names is hard, it's patched, carry on.
I promise, the longer version is more interesting and fun to read!
Recently, I was poking around Ansible Galaxy and almost accidentally got access to someone else's namespace. I was actually looking for something completely different, but accidental finds are the best ones!
If you're asking yourself: "what the heck is he talking about?!", let's slow down for a moment:

November 29, 2021, 7:53 AM
I just spent an unspeakable number of days typing to produce something that
sounds very un-impressive: an FLTK widget that can display an image. The docs
and code live here. The big difference from the usual image-drawing widget is
that this one uses OpenGL internally, so after the initial image load, the
common operations (drawing, redrawing, panning and zooming) are very fast. I
have high-resolution images in my projects, and this will make my tools much

Wouter Verhelst: GR procedures and timelines
November 28, 2021, 7:04 PM
A vote has been proposed in
Debian to change the formal procedure in Debian by which General
Resolutions (our name for "votes") are proposed. The original proposal
is based on a text by Russ
Allberry, which changes a number
of rules to be less ambiguous and, frankly, less weird.
One thing Russ' proposal does, however, which I am absolutely not in
agreement with, is to add a absolutly hard time limit after three weeks.
That is, in the proposed procedure, the discussion time will be two

Joachim Breitner: Zero-downtime upgrades of Internet Computer canisters
November 28, 2021, 5:11 PM
TL;DR: Zero-downtime upgrades are possible if you stick to the basic actor model.
DFINITY’s Internet Computer provides a kind of serverless compute platform, where the services are WebAssemmbly programs called “canisters”. These services run without stopping (or at least that’s what it feels like from the service’s perspective; this is called “orthogonal persistence”), and process one message after another. Messages not only come from the outside (“ingress” calls), b...

Dirk Eddelbuettel: nanotime 0.3.4 on CRAN: Maintenance Update
November 24, 2021, 10:00 PM
Another (minor) nanotime release, now at version 0.3.4, arrived at CRAN overnight. It exports some nanoperiod functionality via a C++ header, and Leonardo and I will use this in an upcoming package that we hope to talk about a little more in a few days. It also adds a few as.character.*() methods that had not been included before.
nanotime relies on the RcppCCTZ package for (efficient) high(er) resolution time parsing and formatting up to nanosecond resolution, and the bit64 package for the actu...
Enrico Zini: Really lossy compression of JPEG
November 23, 2021, 6:58 PM
Suppose you have a tool that archives images, or scientific data, and it has a
test suite. It would be good to collect sample files for the test suite, but
they are often so big one can't really bloat the repository with them.
But does the test suite need everything that is in those files? Not necesarily.
For example, if one's testing code that reads EXIF metadata, one doesn't care
about what is in the image.
That technique works extemely well. I can take GRIB
files that are several megabytes in...
Jonathan Wiltshire: Mischief managed
November 22, 2021, 10:50 PM
I’m finally paying up a certain amount of household technical debt, including investigating some exciting mystery cabling and insulating the space it inhabits. This has meant pulling down large chunks of ceiling (eventually, most or all of it for the insulation) on a cable hunt.
Turns out the best tool for this part of the job is a decent length of 4 by 2, some borrowed muscle, and a certain amount of bravery. Once a couple of holes have been cut the old-fashioned way to be sure there’s n...
Ricardo Mones: Claws Mail 4 in experimental
November 22, 2021, 9:49 AM
A full month has passed since Claws Mail 4.0.0 was uploaded to Debian experimental, and, somewhat surprisingly, I've received no bug report about it.
This of course can be either because nobody has been brave enough to install it or because well, it works really nice.
For those who don't know what I'm talking about, just note that this version is the first Debian upload for the GTK+3 version of Claws Mail. There was an initial upstream release, namely 3.99, but it was less polished and also I wa...
Paul Tagliamonte: Be careful when using vxlan!

I’ve spent a bit of time playing with
vxlan - which is very neat, but also incredibly insecure by default.When using vxlan, be very careful to understand how the host is connected to the internet. The kernel will listen on all interfaces for packets, which means hosts accessable to VMs it’s hosting (e.g., by bridged interface or a private LAN will accept packets from VMs and inject them into arbitrary VLANs, even ones it’s not on.I reported this to the kernel mailing list to no reply with ...

Z3 is a theorem prover developed at Microsoft research and available as

Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 928 other packages on CRAN.

Christoph Berg: PostgreSQL and Undelete
November 17, 2021, 3:46 PM
Earlier this week, I updated pg_dirtyread
to work with PostgreSQL 14.
pg_dirtyread is a PostgreSQL extension that allows reading "dead" rows from
tables, i.e. rows that have already been deleted, or updated. Of course that
works only if the table has not been cleaned-up yet by a VACUUM command or
autovacuum, which is PostgreSQL's garbage collection machinery.
Here's an example of pg_dirtyread in action:

Paul Tagliamonte: Measuring the Power Output of my SDRs ⚡
November 16, 2021, 3:06 AM
Over the last few years, I’ve often wondered what the true power output of my
SDRs are. It’s a question with a shocking amount of complexity in the
response, due to a number of factors (mostly Frequency). The ranges given in
spec sheets are often extremely vague, and if I’m being honest with myself,
not incredibly helpful for being able to determine what specific filters and
amplifiers I’ll need to get a clean signal transmitted.
Hey, heads up! - This post contains extremely unvalidated...
Vincent Bernat: Git as a source of truth for network automation
November 15, 2021, 7:53 AM
The first step when automating a network is to build the source of

intended state: the list of devices, the IP addresses, the network
protocols settings, the time servers, etc. A popular choice is
NetBox. Its documentation highlights its usage as a source of

its operational state. As such, automated import of live network

Ruby Team: Ruby transition and packaging hints #2 - Gemfile.lock created by bundler/setup with Ruby 2.7 preventing successful test with Ruby 3.0
November 14, 2021, 3:25 AM
We currently face an issue in all packages requiring bunlder/setup and trying
to run the tests for Ruby 2.7 and 3.0. The problem is that the first tests will
create Gemfile.lock (or gemfile/gemfile-*.lock) using Ruby 2.7 and the next
run for Ruby 3 will report e.g.:

During the Ruby 3.0 transition there are essentially two different Ruby
versions with two different binaries available, /usr/bin/ruby2.7 and
/usr/bin/ruby3.0, while /usr/bin/ruby points to the current default
version, which is Ruby 2.7.
In some cases the tests shipped by the source packages will use shell c...
John Goerzen: Managing an External Display on Linux Shouldn’t Be This Hard
November 13, 2021, 4:21 PM
I first started using Linux and FreeBSD on laptops in the late 1990s.  Back then, there were all sorts of hassles and problems, from hangs on suspend to pure failure to boot.  I still worry a bit about suspend on unknown hardware, but by and large, the picture of Linux on laptops has dramatically improved over the last years.  So much so that now I can complain about what would once have been a minor nit: dealing with external monitors.

My eldest daughter and I visited a LEGO shop recently and I wanted to buy her

day, so I wanted to find something with the lowest risk of losing parts on
the plane.
We settled on Ariel, Belle, Cinderella and Tiana's Storybook
which had a number of things going for it: It was reasonably priced at under

Neil Williams: LetsEncrypt with Apache, Gunicorn and Debian Bullseye
November 10, 2021, 4:03 PM
This took me far too long to identify and debug, so I'm going to write
it up here for my own reference and to possibly help others.
Upgrading an old codebase from Python2 on Buster to Python3 ready for
Bullseye and from Django1 to Django2 (prepared for Django3). Everything
is fine at this stage - the Django test server is happy with HTTP and
it gives enough support to do the actual code changes to get to
Python3. All well and good so far. The main purpose of this particular
code was ...

Craig Small: Changing Grafana Legends
November 10, 2021, 6:25 AM
I’m not sure if I just can search Google properly, or this really is just not written down much, but I have had problems with Grafana Legends (I would call them the series labels).  The issue is that Grafana queries Prometheus for a time series and you want to display multiple lines, but the time-series labels you get are just not quite right.
A simple example is you might be using the black-box exporter to monitor an external TCP port and you would just like the port number separate to dis...
Benjamin Mako Hill: The Hidden Costs of Requiring Accounts
November 9, 2021, 7:55 PM
Should online communities require people to create accounts before participating? This question has been a source of disagreement among people who start or manage online communities for decades. Requiring accounts makes some sense since users contributing without accounts are a common source of vandalism, harassment, and low quality content. In theory, creating an account can deter these kinds of attacks while still making it pretty quick and easy for newcomers to join. Also, an account requ...
Joachim Breitner: How to audit an Internet Computer canister
November 9, 2021, 5:34 PM
I was recently called upon by Origyn to audit the source code of some of their Internet Computer canisters (“canisters” are services or smart contracts on the Internet Computer), which were written in the Motoko programming language. Both the application model of the Internet Computer as well as Motoko bring with them their own particular pitfalls and possible sources for bugs. So given that I was involved in the creation of both, they reached out to me.
In the course of that audit work I co...

Dima Kogan: mrcal 2.0: triangulation and stereo
November 8, 2021, 10:40 PM
mrcal is my big toolkit for geometric computer vision: making models (camera
calibration) and using models (mapping, ranging, etc).
Since the release of mrcal 1.0 back in February I've been busy using the tools
in the field, fixing things and improving things. Today I'm happy to finally be
able to announce the release of mrcal 2.0.
A big part of this release is maintenance and cleanup that resulted from me
heavily using the tools over the course of this past year, and improving
whatever wa...
