6 ways to minimize script startup overhead
Steven Haryanto lists 6 ideas. Some are really good, though I don't agree with all the strategies. I liked the idea of checking the cost of a module using Devel::EndStats (in his pmcost script). Using require for modules that are not used on every run is a clear win. What do you think?

Some lessons in optimizing Org::Parser
What do you do if your notebook is small and slow? Steven Haryanto had to profile his perl scripts to make them run at a reasonable speed. I liked the way the story is told.

List of Perl modules comparison articles
In recent years there were several articles comparing modules for specific task. Steven Haryanto created a wiki page with the hope of linking to all such comparison articles.

Steven Haryanto describes how he separated the progress reporting from the normal logging mechanism he uses. The result is Progress::Any. So instead of a long and confusing output he had to manually look through, now he can easily see the encountered problems and the current status of a long-running script.

Categorizing CPAN modules
Steven Haryanto brings up the age-old problem of difficulty in finding things on CPAN. All kinds of suggestions were raised, mostly around MetaCPAN. Actually there is a site that already provides the possibility to tag modules, but unfortunately CPAN::Forum never got really off the ground and in recent years I did not have any time to work on it.

CGI is dead, long live CGI
'CGI might be out of favor for production sites, but for personal and internal applications, it's still the best choice for me.' writes and explains Steven Haryanto. Then in the comment section you'll see how PSGI wins even when you want to run as CGI.

Graphing CPAN author's number of distributions over time
Steven Haryanto create a short script using the Meta CPAN API, to fetch the number of distribution of give CPAN developers and then put that on a graph. He is using bare metal API calls getting back JSON structures and then uses Chart::Lines to draw the graph.

Breaking users of old versions of a module
An interesting article by Steven Haryanto discussing how to handle backward incompatible changes. One of the approach is to keep the old behavior in a separated module and allow the user to specify which behavior they want to have at the use-time of the module.

How I manage my Perl distributions
There are some large Perl-based applications out there that use their own way of packaging and distributing the code, but Steven Haryanto believes it is better to use the same toolchain as is used for CPAN distributions. Even if the application does not end up on CPAN. Even if it is an in-house or other proprietary application. (I tend to agree.) In this article he describes how he handles the process.

Things we don't have #1
While CPAN has lots of modules solving many problems (multiple times), there are many problems that are not, or not well solved. Steven Haryanto started to put together a list of tools (libraries) available in other languages but not in Perl. In case you are looking for an problem to work on.

2016.03.04 in #241
Fixing prereqs in dist.ini automatically
Perlancar's lint-prereqs script can be used to check whether your distribution has (the right versions of) all the right prereqs, and if you're using Dist::Zilla it can even fix up your
dist.ini. I've never had any problems using
[AutoPrereqs], but I know that not everyone does.
