Network and USB printing with Brother printers generally work great on Linux and Windows Subsystem for Linux.
The Brother installer script automatically downloads and installs necessary programs.
Opt out of the last program brscan-skey, as it’s unnecessary.
“Will you specify the Device URI? [Y/n]” y (if networked)
“Specify IP address”: “Enter IP address” the static IP printer address
BRscan: YES allows xsane for Brother scanning printers.
BRsaneconfig: YES xsane scanner over the network
BRscan-Skey: NO don’t install because of potential security risks.
If accidentally installed brscan-skey, uninstall with
dpkg -r brscan-skey
As usual, manage/check printer from CUPS by pointing your PC web browser to localhost:631
Scanning documents in Linux in typically done with Xsane, which works on networked or USB connected scanners.
apt install xsane
xsane
To update scanner IP address use brsaneconfig4
For native Windows (not using Windows Subsystem for Linux), download just the driver that is about 15-20 MB and add the printer by IP address and choose “have disk”, pointing to the folder where you extract the drivers files to.

is reasonably accurate at automatically detecting the percentages of each code language in Git tracked code.
However, as with any automatic coding language detection scheme, mis-detected languages occur.
This seems to happen most often with Matlab code.
Despite being in the top 10 STEM / data science languages, Matlab / GNU Octave *.m files can be detected as other languages such as Objective-C or Limbo.
Matlab can adjust for
HiDPI (2K, 4K, etc.) displays.
HiDPI Matlab IDE resolution (icon and font size) can be manually corrected from within Matlab on any operating system.
Matlab has programmatic DPI access to get / set information on DPI as well as numerous other Matlab characteristics via
settings.
This is a basic example of using FORD to document Fortran projects.
FORD is a Python program:
pip install ford
Each project will have a ford.md that configures and makes description for the main project landing page.
If your code is all under the top-level directory, set ford.md like: (this example is for the fortran2018-examples repo)
src_dir: ./
output_dir: ./docs
project: Fortran 2018 examples
project_github: https://github.com/scivision/fortran2018-examples

Within the Fortran code, use `!!` on each line with Markdown, Latex, etc.
Never assume that eager or short-circuit evaluation of logical statements will occur in Fortran.
Fortran standards from Fortran I (1957) through Fortran 2018 do not mandate or prohibit
short-circuit logic.
That has resulted in some compilers (e.g. Gfortran) sometimes using short-circuit logic, while other compilers (e.g. Intel) do not use short circuit logic.
This causes breakage when the programmer tests with one Fortran compiler handles compound logic with eager evaluation, but other compiler uses short-circuit evaluation.
Compilers not short-circuiting (standard Fortran behavior):
Gfortran -O0
NAG
Intel
Short circuiting (non-standard behavior)
Gfortran -O1 or higher
Proper handling of compound logic in Fortran: one should carefully avoid assumptions that either eager or short-circuit evaluation of compound logical statements will occur, because neither is guaranteed by any Fortran standard.
Assuming eager evaluation of Fortran logical statements, this can cause breakage where a function that’s part of the statement has side effects.
For example, a function that modifies a module variable, or simply an intent(inout) variable will find those variables unmodified if a compiler uses short-circuit logic.
Fix: break up the compound if statement so that the function is always evaluated (e.g. just before the if statement).
Assumptions that short circuit evaluation occurs commonly causes breakage of present(arg) for optional :: arg optional dummy arguments.
subroutinemyfun(a,b)real,intent(inout)::areal,intent(in),optional::b! don't do this!
if(present(b).and.b<0)a=b*a! instead, do this:
ifpresent(b)thenif(b<0)a=b*aendif
OpenMPI is often available from package managers across computing platforms.
Users might build OpenMPI from source to get the latest version or to support other compilers.
OpenMPI takes several minutes to build.
