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 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! Gabor Szabo |
