"Electricity Maps" is fascinating! You can visualise a map showing a selection of realtime and historical eletricity use and approximate associated carbon emmisions.
A real eye-opener. Europe and UK is doing quite well, very suprising that Australia apparently isn't making use of that abundant sunshine!
Add the "wind" and "solar" layers for a kickass screensaver..

I'm a big fan of Yellow Lab Tools; they bring a different perspective to visualising performance to other tools.

I heard on a recent #dotnetrocks that someone did an Advent of Code one year entirely in Rockstar!
Anyone fancy doing the second album?..

In case anyone working on private #webpagetest installs is wondering, it was this func that fails silently (until you add some "curl_error" logging to see that it's timing out...):

(as in, I've locked it down so the WPT server is essentially private)
Options were:
a) add a `local_server` entry to settings.ini ("application" change)
b) add the wpt server's security group to itself as allowed ingress? I guess? (infra change)I went with a) so the async requests went via 127.0.0.1 instead.
Seems to have worked!
I had to add "fwrite()" calls to soooo many files in the #webpagetest source code to understand what was calling what and why it worked when I hit a URL directly..

1) managed to migrate my stuff to ARM / t4g EC2 instances, so I'll keep an eye on AWS spend to see if it actually helped 🎉
2) finally debugged why videos weren't being created on my private #webpagetest instance - took me an insanely long time to realise that an async php function, calling itself via php curl, was silently timing out, due to using the public dns, which is mega locked down 🤦🏻 -

A bit of a brain dump on #webdev, #decisionmaking and some reminiscing about the early years at #Asos

Ouch. The PHPStan output for #webpagetest on php8 is scary. Nothing seems to be functioning as expected.. Think I better just back away for the time being, and lock my versions until I want to dive head first into #PHP development
-
Ah of course. A new month rolls around, ubuntu change their most recent LTS AMI from Focal to Jammy, and my #webpagetest deployments fail 🤦🏻
That'll teach me to use wildcards in the AMI search...

I've been professionally coding since the late 90s.
I have zero "side hustles" (but dozens of unfinished ideas).
My plan of vast sums of passive income has been scuppered by my lack of "side hussle" motivation.
Damn this brain of mine.
