Hi there!
As you might know I used to teach Perl and helped companies using Perl.
Unfortunately, in the last couple of years only a few companies asked for
my help with Perl and in most cases in areas I am not that familiar with.
So I referred them to other, well known consultants.
Instead of Perl most of my clients are asking for help with Python and
Rust. Especially because of the latter I felt the need to know more about C
and C++. At least to the level where I understand the questions C/C++
programmers might have about Rust. So I dusted off my copy of "The C
programming language" and started to learn again.
This time it will be especially fun as my son - who has been a professional
programmer for more than 6 years now - decided to get a degree in Computer
Sciences so he is also taking classes about C.
The way I learn is by trying to implement things and trying to explain
them. So I am going to post about my new journey with C on the C Maven (
https://c.code-maven.com/ ) web site. You have been warned.
In other news we are celebrating Purim this week, when everyone dresses up
as someone else. I wonder if I should dress up as a C programmer?
Enjoy your week!

Don't you love the method chaining of Raku? It allows you to create cute
little one-liner. You must checkout to see it yourself.

Hi there!
=20
As you might know I used to teach Perl and helped companies using P=
erl. Unfortunately, in the last couple of years only a few companies asked =
for my help with Perl and in most cases in areas I am not that familiar wit=
h. So I referred them to other, well known consultants.
=20
Instead of Perl most of my clients are asking for help with Python =
and Rust. Especially because of the latter I felt the need to know more abo=
ut C and C++. At least to the level where I understand the questions C/C++ =
programmers might have about Rust. So I dusted off my copy of "The C progra=
mming language" and started to learn again.
=20
This time it will be especially fun as my son - who has been a prof=
essional programmer for more than 6 years now - decided to get a degree in =
Computer Sciences so he is also taking classes about C.
=20
The way I learn is by trying to implement things and trying to expl=
ain them. So I am going to post about my new journey with C on the =3D"https://c.code-maven.com/">C Maven web site. You have been warned.
=20
=20
=20
In other news we are celebrating Purim this week, when everyone dre=
sses up as someone else. I wonder if I should dress up as a C programmer?
=20
Enjoy your week!
