Commented on Response header name ' Content- type' contains invalid characters, after running a Perl_CGI script.
I would note that posting something like this on https://stackoverflow.com/ and tagging it with #perl will get you helpful feedback quite quickly....

Posted Cloud Provider Performance & Price Comparison 2023 to Dimitrios Kechagias
Last year I compared the various VM types of 7 popular cloud providers mainly for Pe…

Commented on ChatGPT for Perl Learning
If you don't already know what you are doing, ChatGPT can be very misleading. It's designed to be the world's greatest bullshitter after all. > ChatGPT, can you give me a regular expression that matches a repeating pattern of two...

Posted Weather::WeatherKit and Weather::Astro7Timer to Dimitrios Kechagias
Today, the popular Dark Sky weather API is shutting down. I did a little write-up for non-Perl devs on DEV.to, but I thought I'd post here a couple of…

Posted Perl performance evolution over the last decade to Dimitrios Kechagias
I was reading recently about some significant Python 3.11 performance improvements, and I was wondering whether Perl 5 still gets significant performance improvements on each version - even though it might be more mature, thus more optimized in the first…

Commented on What happened to Perl 7?
IMHO announcing Perl 7, which was picked up by the non-perl community as clear "signs of life" from what they thought of as an irrelevant/dying language, and then taking it back was quite a big step backwards, so I'd thought...

Commented on Cloud Provider Performance Comparison - Perl & more
Thanks for the comment. The reason I included just Linode and Digital Ocean from the "smaller" providers, is because they have good reputation (Linode's been around for almost 20 years now) and I personally have good experience with them. I...

Posted Cloud Provider Performance Comparison - Perl & more to Dimitrios Kechagias
Last year, impressed with the apparent speed of an M1 Mac Mini I bought to try out, I explored its perl performance and wrote about it in a blog post. I used mainly my own benchmarks which were mostly…

Commented on Perl performance on Apple M1
A bit late, but you might enjoy my DKBench, which is similar to what I did above, in a single test-suite, made for subsequent perl benchmarking which will probably end up in another blog post....

Commented on Perl performance on Apple M1
I wrote about it above, it was my first idea, which is why I ran powermetrics to make sure, and indeed it is still using the performance cores, same profile as before the sleep/wake cycle, so no idea what happens....

Commented on Perl performance on Apple M1
Apart from the last two that are proprietary, all the others have the full code here (if they are programs, otherwise the exact command I run with time). Not sure what more a github repo would do? Is there something...

Posted Perl performance on Apple M1 to Dimitrios Kechagias
I recently got an Apple M1 Mac Mini, half out of curiosity, half because it was exactly what I would need: I have a low end Mac just to try out things like new Xcode betas etc, like a "canary" machine. My old 2012 Mac Mini stopped getting official Apple…

Perl performance on Apple M1
What I mean is to wrap up what you can in a script so its quick and easy for someone to replicate. Spitting out a result that can be compared to other results.

What happened to Perl 7?
Thank you for such a clear update. As somebody who only manages intermittently to follow what's happening with the Perl core, this is really useful, and explains several things I'd be wondering about.

ChatGPT for Perl Learning
Perl is like the sharp guy in the back office who can solve any problem fast and efficiently. Doesn't care about the "fashion du jour" - just what works and is efficient. And then are the "me too"s, who spent their time sensing the daily winds and making sure they are sexier than the next one. And that's how they win the hearts and minds of the most young and superficial minds. But every now and then there is a "fashion" that is the real thing and somehow perl made a few bad bets.
