Perl Weekly #659 - The big chess game

Originally published at Perl Weekly 659

My father was a chess player. In his best time he was sometimes called "the best non-Russian chess player". He survived WWII and the Holocaust in a Hungarian forced labor camp and in Russian POV camp. When he got back to Hungary all he wanted to do is get back to chess. He did not want to care about 'politics'.

In the 90s he often lamented that he did not pay enough attention to what went on in Hungary in the 50's. That he was not aware of the communist atrocities in Hungary and neighboring countries.

I have been publishing the Perl Weekly for more than 12 years. In the first 9-10 year I think I have never mentioned anything besides Perl or related technologies. I wish I could keep focusing on technology only. Unfortunately I don't have that luxury any more.

Frankly, if we paid more attention to what's going on outside of Perl and outside of technology in general, maybe we would not be in such a bad situation.

On a related subject, I hear Garry Kasparov was added to the list of 'terrorists and extremists' by Russia.

We can't change the past - well, some do it anyway by lying about history - but we also cannot claim we did not know. We want to bring them home!

Have a better week!

Pointless personal side projects

I think only a very little subset of programmers have such side projects and an even smaller subset write articles about these projects. For most people programming is a 9-5 job. It is not that others aren't as good or don't enjoy programming. It is just that they might have different hobbies, or no time for hobbies at all. Comment on Reddit or on

Some guidance how to set this up

A very non-descriptive title for some logging/debugging advice.


A little confused about cpan

How to remove packages?

Is there a better way to write this alienfile?
