[ANN] Austin -- Python frame stack sampler for CPython v1.0.1 is now available

[Gabriele]

I am delighted to announce the release 1.0.1 of Austin. If you haven't
heard of Austin before, it is a frame stack sampler for CPython. It can
be used to obtain statistical profiling data out of a running Python
application without a single line of instrumentation. This means that you
can start profiling a Python application straightaway, even while it's
running on a production environment, with minimal impact on performance.

The simplest way of using Austin is by piping its output to FlameGraph
for a quick and detailed representation of the collected samples. The
latest release introduces a memory profiling mode which allows you to
profile memory usage.

Austin is a pure C application that has no other dependencies other than
the C standard library. Its source code is hosted on GitHub at

https://github.com/P403n1x87/austin

The README contains installation and usage details, as well as some
examples of Austin in action. Details on how to contribute to Austin's
development can be found at the bottom of the page.

Austin v1.0.1 is also the first version of Austin to be available from 
Homebrew
for easy installation on MacOS. These are the other places where Austin 
can be
downloaded

Linux:
- Snap Store
- Debian repositories

Windows:
- Chocolatey

Furthermore, you can stay up-to-date with the project's development by
following Austin on Twitter (https://twitter.com/AustinSampler).

All the best,
Gabriele

I appreciate that a lot!  But of course if that's your view of things,
then you are the great one here.  No doubt about it.  Have a great day!

Thanks a lot. That's really great.

In the meantime I switched to pytest because things are so much more
convenient to setup. So, also thanks to the others who gave the links to
how this can be done with pytest.

Problem installing Python

[Aisha Akintola]

Good day,
I downloaded python(python3.8.3) on my system (windows 8) to enable me use
PyCharm. However, I realised the python wasn't well installed. I get
message "the program can't start because api-ms-win-crt-runtime-I1-1-0.dll
is missing from your computer. Try reinstalling the program to fix
this problem'.
I have reinstalled but got the same error message; what should I do?
Thank you

You cannot attach any screenshots because the list strips them. You will
have to provide your errors and your tries as an inline text in the email
(copy and paste the error).
