Switching to CMake from autotools or plain Makefiles gives generally better support of many operating systems, in particular Windows.
Another benefit is generally faster speed of configuration and build.
In 2020, MonetDB
switched from autotools to CMake.
They observed MonetDB with CMake builds in 40% of the original time.
Note also the improvement due to Ninja instead of GNU Make.
We have converted a number of projects from autotools to CMake.
Consider automated
autotools to CMake script
and then manually compare or redo by
inspection
of the autotools scripts.
In general, livestream data bandwidth depends on the video content (lots of motion vs. talking head) and wireless conditions.
YouTube Live has a wide range of
livestreaming modes.
Consider 480p to start to keep the connection from dropping out, with data bandwidth of 500 - 2,000 kbps ~ 16 Mbyte/minute.
Use variable bitrate to dramatically reduce upload bandwith needed for typical livestreaming scenes.

Hugo
shortcodes
are a powerful, easy way to template code used in blogs and websites.
Ana Ulin describes a
one-line Hugo shortcode
to inline HTML in Hugo:
Under the top-level Hugo website Git directory, add file “layouts/shortcodes/rawhtml.html” containing:
{{.Inner}}
Then in the Markdown file for the particular blog post, do like (removing the space between the left brace and the left caret):
Compare files between Git branches with a GUI like
VS Code
or
Meld,
showing all files different between the current Git branch to another Git branch “develop”:
git difftool develop
Compare a single file to another Git branch “develop”:
For projects consisting of more than a few files, or of files in different code languages, it can sometimes be beneficial to only run certain workflows depending on which files changed.
For example, consider a Fortran-based simulation where the CI takes minutes or hours to run, with associated Python plotting code.
If only the plotting code is changed, it might not be necessary to CI the entire simulation, but instead test just the Python code.
This can be arranged via separate .yml files under the repo’s .github/workflows/ directory.
Example: only run Python analysis script tests (say, under “scripts/”) when analysis scripts are changed.
If Fortran code or Python interface scripts are changed, run other CI.
Matlab
mustBeA
is used in
function argument validation
to check that a variable is in one of multiple classes, instead of the single class coercion used by Matlab arguments block by default.
Simply create a file in the project directory “mustBeA.m”, or under private/mustBeA.m
functionmustBeA(x, classes)% for Matlab < R2020barguments
x
classes (1,:) string
endmustBeMember(class(x), classes)
end
Matlab
mustBeFile
and
mustBeFolder
can fail to validate when the filename starts with a tilde “~”.
Tilde is used by most terminal shells to indicate the user home directory.
However, Matlab does not currently recognize tilde.
Workaround this issue with
expanduser.m
in the mustBe* call.
Example: myfun.m:
functionmyfun(A, B)arguments
A {mustBeA(A, ["string", "char"])}
B (1,1) {mustBeNumeric}
end...end

IANA
RFC8615
defines a “.well-known/” folder for web servers to put metadata fundamental to a web server’s organization, policies or contact information.
Several popular files are seen under public website “https://example.invalid/.well-known/" directory.
The 2020 movie “The Midnight Sky” is based on the 2016 Lily Brooks-Dalton book
Good Morning, Midnight.
I customarily approach book-based films by reading the book first.
This review is only about the book.
I found the character-oriented narrative quite compelling, with multiple characters having development and reflection.
The only slight downside to the book is as typical in most fiction (including post-apocalyptic and science fiction), the radio communications and vehicle aspects of the book could have been described more accurately by having a technical reviewer.
I think the author did a better than average approach to the radio comms, minus the glitches noted below.
I compliment the author’s approach–these slight issues are endemic in fiction books.
Contradictions I notice involved transportation and radios comms.
A gasoline engine that has a pull rope start is subsequently described as having a dead battery and therefore unable to start.
In fact, it’s possible in some cases to improvise a pull start on small electric start engines.
Since another similar vehicle is described as having electric start, this may have been an editing mistake (perhaps the final intent was to have both vehicles be electric start).
The author’s ham radio callsign is used by a character–cute!
The author could have more specifically addressed LEO satellite comms window for simplex VHF comms.
The characters could simply say VHF / UHF, as it’s uncommon to spell out the abbreviated terms.
There are frequent references to RF sine waves, when actually random noise was seemingly implied.

What really happened to Augie:
Did Augie even leave the observatory for the lake camp? If the snowmobile travel was real, did Augie actually die on the way? In the real world Google Maps, it's quite a trip, even with vehicles. The time at the camp is quite idyllic, giving hints it was a dying vision. While the radio comms with Aether seem "real", the book strongly hints they could have easily taken place from the observatory.
