• 2011.09.08 in #7 Lessons from running Perl Weekly for the first 6 weeks
  This is another article I wrote, this time on my own blog, describing my experience with this list. It might be interesting to you if you'd like to look a bit at the details. I am also comparing the experience with that of Peter Cooper who runs the Ruby Weekly which was the inspiration to this newsletter.
• 2011.09.09 in #8 Which is the better language to learn Perl or PHP?
  I wrote this article in response to a question I got. I tried to make the comparison related to the job opportunities. The article was quite popular but the strange thing was that some of the comments on Google Plus and Twitter related to the relative qualities of the two languages and not the career opportunities.
• 2011.09.26 in #9 Perl Polls: What articles would you like to read?

• 2011.11.03 in #15 Testing a simple Perl module
  When starting a new module it is very easy to start writing unit tests from the beginning.

If you are interested, please subscribe.
• 2011.11.03 in #15 Lots of new entries in the Perl Tutorial

• 2011.11.15 in #17 How to teach 'Modern' Perl?
  People have strong opinion on what Modern Perl means. Unfortunatelly those things don't always work out of the box and sometimes it isn't a good thing to teach those practices at all. At least not as the first experience in tha language. In this article I was trying to discuss some of the issues I see.
• 2011.11.27 in #18 Beginner Perl Maven
  Announcing the first online video course I started to record. This is for people learning Perl. There is a special discount coupon for those visiting this page in the next day or so. Feel free to invite your friends to use this discount. It expires in less than 3 days.

The two parts of the Beginner course also have discount codes: 'beginner_15' and 'beginner2_15' respectively for $15 instead of $39 each.

• 2012.01.10 in #25 How to read a CSV file using Perl?
  When parsing an CSV file one would probably start using split() just to find out soon that it only works in simple cases. For more complex cases Text::CSV_XS is a much better solution.

  IMHO for beginners it's quite hard to find explanation on what are the special variables of Perl. Especially $_ is confusing people and search engines. I hope my little contribution helps.

  I took a regex related question I saw on PDX.pm and described how I'd build the regex step-by-step. The string isn't too complex: 'Usage:524944/1000000 messages' but I hope this approach can help people learn how they can go about building a regular expression.
• 2012.02.25 in #31 What is a Perl Monger group for?

The Cookbook is given exclusively (and free of charge) to the people who subscribe to the Perl Maven newsletter.
• 2012.08.10 in #55 Enlightened Modern Perl or useful Perl?
  OK, this is not the only link from my sites, but this one is without technical content. It is a dilemma I have. You might want to share your opinion.
• 2012.09.08 in #59 The most popular Perl web sites
  I created a list of perl-related web-sites and checked their rankings using Alexa. Here you can see the most visited sites. A few people were missing their own sites from the list, but actually I was hoping for more people to complain and give me ideas what other sites to track.
• 2012.09.15 in #60 23+2 Perl based open source products
  This is the list of basically all the Perl-based open source products I could find. I used Alexa for ordering them, but that's not the point. The point is to understand the types of products built with Perl and if they are backed by one or more businesses or if they are volunteer based.
• 2012.09.27 in #62 Announcing the Perl Maven Competition
  Some other languages already have it. It's time for the Perl developers to show the world they can also build beautiful applications. The planning has started.

• 2013.07.18 in #104 Compiling Perl, Python and Ruby
  Comparing the default installation size of the 3 major dynamic programming languages. Perl is the smallest, but Pythons has a lot of batteries included. There are many modules in the standard library of Python, that are missing from from the standard installation of Perl and thus require extra steps to install them from CPAN.
• 2013.08.01 in #106 Three month after domain name change
  Once in a while I collect numbers from various sources trying to see how the Perl Maven site does and compare that with other Perl-related sites, and with sites related to PHP, Python and Ruby.

• 2014.03.12 in #138 How did PHP and Python take over such a huge market-share of Perl?

Gabor shows us the difference.
• 2014.04.29 in #145 GitTip and the Perl Community
  In a nutshell, I think if all the people who benefit from Perl contributed back to the community, the Perl ecosystem could do a lot more. So if you cannot contribute time, maybe you can contribute some money. GitTip is an easy way to do so.

Judging by the comments on Reddit there are quite a few people who prefer to spew hatered than to be constructive. We'll see.
• 2015.01.01 in #180 Continuous Integration for Perl 6 modules using Travis-CI

• 2019.05.06 in #407 Add (conditional) debugger breakpoints to your code
  What if you have a loop that you'd like to debug but only after it passed 10,000 iterations? Use conditional breakpoints.

  I have been running training courses in class-rooms for ages, but those have a geographical limitation.

I wonder if you'd be interested in workshops or full-length courses I run online for a reasonable fee? The main topics I offer: Docker, Git, GitHub, Linux (Bash), Test Automation, CI (Jenkins, Travis-CI) Cloud, Perl, Python, Golang. Let me know what would be interesting to you and in which timezone are you in by sending an e-mail to gabor@szabgab.com !

It will run via Zoom and we'll probably use Cyber Dojo. It supports Perl 5, though it does not support Raku. Yet. I have hopes that by that time the Raku developers will be able to send a PR to the maintainers of Cyber-Dojo or that we'll have an alternative that also supports Raku. If you are interested to join, send me an e-mail (gabor@szabgab.com), and I'll send you an invitation.

Some of them already have a short explanation about the technologies involved.
