Issue #479 - 2020-09-28 - Muhammad and the mountain

Hi,

It has been more than 9 years since I started the Perl Weekly and I am still surprised that most people who organize Perl-related events don't utilize the Perl Weekly as a tool to promote their events. I understood it better when the events were local and people already had the local Perl Mongers groups, but now that everything can be global it is really strange.

They don't even need to talk to me to be added, it is enought to send a pull-request to a JSON file.

But what can I do, so if the mountain does not come to Muhammad then Muhammad has to go to the mountain, right? So I've subscribed to three Meetup groups where Perl monger events are being organized and you can see the events at the end of the newsletter or on the events page.

Enjoy your week and attend an on-line Perl event!

Gabor Szabo

Perl in the outside world

The Perl Tag on dev.to

As Dave Cross suggested and many applauded a nice way to promote Perl is to blog about Perl-related subjects on generic sites. For example Dev.To. If you do make sure you also add the Perl tag to it to make it easier for Perl developers to find them and upvote them.

DevOps, CI/CD, and Automation assesment questions

A potential client sent me an e-mail that they are interested in automation and having CI/CD. (Nowadays this became a single entity.) I started to write down some question I need to ask them to understand their current situation and what are their goals.

Minimal requirements for a blog

by Gabor Szabo (SZABGAB)

A while ago I started to think about a project in which I would implement a blog engine (possibly to replace bpo) and follow the development with screencasts. Now that Davorg started to talk about not having a central blog engine and that he also set up his Perl Planetarium, it might be better to do something else with my time. In any case I am posting the notes I made in case someone else is interested.
