Hi there!

There were not many posts this week, but some of them were really interesting.

Personally I got a bit overwhelmed with work. It is very interesting that there are organizations where people don't know how to use git properly, where they hardly have any tests and no CI is running, but they already have Kubernetes set up because some consultant thought that would be cool to use it.

On one hand it makes me angry that people don't introduce testing, CI, and CD early in the development process. It would be a lot cheaper, smoother and faster for them, but on the other hand I also like trying to figure out how things happen to work. Sometimes, it seems, by total chance.

Enjoy your week!

The Funhouse Mirror of Perl Criticism

by Mark Gardner

An excellent article about the tools you can use to improve the way you and your team writes Perl code. However, how can you make sure you don't break your code while you implement the changes recommended by these tools?

Zapp: Runbook Automation

by Doug Bell (PREACTION)

I did not know what a runbook is, I guess it is something others call a checklist. What I do know is that I agree about the problems with Jenkins and I'd love to see something like this being developed. It can be an excellent tool for SREs and people whom are often called DevOps engineers. IMHO, in order to make it catch on it needs its own web-site that is not MetaCPAN. It needs to have an installation that does not require any knowledge of Perl. These are two big areas where others could help the project. Of course 'just' using it and reporting any issues would also be extremely valuable.

Perl UV binding hits version 2.000

libuv is a cross-platform event handling library, which focuses on providing nicely portable abstractions for things like TCP sockets, timers, and sub-process management between UNIX, Windows and other platforms. UV is the Perl bindings for it.

Are you using Cache::Memcached and its ->stats method?

by Lee Johnson (LEEJO)

A module that is probably used by some large projects, but not maintained any more. Without a link to its public VCS, if it even has a public VCS. Probably the best approach would be to reach out to the original author and the author of the most recent release via their email or social network profiles.
