I jotted down a few thoughts on current situation around RuboCop's name here I haven't felt so disappointed and depressed in a while and I'm seriously wondering whether I want to be a part of a community that attacks people in such a way.

I've distilled my thoughts on the RuboCop rename drama (RuboDrama?) in a blog post I hope we can put yesterday's negativity behind us and move on. I also hope we can show the Ruby community's better (real?) side going forward.

What a fantastic announcement by Cognitect and Nubank! I'm really surprised, touched and honored by their support. Seems Christmas came early this year!
P.S. I hope that Cognitect's example will inspire more companies to help support the open-source ecosystem.

I think it's safe to say that Emacs is the text editor with the most dedicated user base (and I have the chart to prove it). We're immune to the VS Code mania! M-x forever! (the chart is from )

My wife just told me that 8 men from her hometown have died yesterday in the battle for Severodonetsk. :( The media have dialed down their coverage of the war in Ukraine, but the war is just as brutal as it was 3 months ago. Remember Ukraine! Героям слава!

My wife's from Ukraine. I've spent a lot of time in Ukraine. I've got family and many friends in Ukraine. I love Ukraine. Today I was woken up early in the morning by my mother-in-law who told us over the phone that Russia has launched air strikes all over the country.

It's really painful to wake up to hostile comments like this one in my twitter timeline. I've spent almost a decade working for the Ruby community and I got vilified over this. Yeah, open-source work is really rewarding. Go do everything better. I'm a horrible person.

Ще разочаровам Копейката, ама повечето избиратели на ППДБ сме напълно доволни от тях и освен да излезем да пием по едно друго няма да правим. Точно днес съм много горд с решенията на парламента и единствените политици от които ме е срам са продажниците от Вгъзраждане и БКП.
Копейкин видя,че неговите избиратели не излизат по улиците и вече плаши,че избирателите на ППДБ ще излязат.

I generally prefer Linux over macOS, but I guess most people like that macOS is close enough and they don't have to worry about driver issues. Running Linux on new hardware is usually somewhat painful. These days Windows + WSL is a great alternative to macOS as well.

I wonder how much more the western powers are going to wait before they take some actual steps to prevent Putin from destroying Ukraine. Arm Ukraine heavily. Cripple Russia with massive sanctions. The best time to act was 8 years ago. The second best time to act is today.

10x engineers are nothing but a (dangerous) myth, but 10x idiots are quite real!
10x engineers
Founders if you ever come across this rare breed of engineers, grab them. If you have a 10x engineer as part of your first few engineers, you increase the odds of your startup success significantly.
OK, here is a tough question.
How do you spot a 10x engineer?

Nothing beats lisp-case/kebab-case when it comes to readability! I challenge you to change my mind!
Unpopular opinion: snake_case is much easier to read than camelCase, and I wish the JavaScript community agreed with me. 🥲

Somehow I totally missed that SICP got a new edition last year that's using JavaScript instead of Scheme Kind of makes sense, given the times, but it certainly makes me a bit sad as fewer people will be exposed to the magic of Lisp going forward.

We forgot an umbrella in a small Chinese restaurant in Nice in February. We returned there today and the owner was like "I recall last time you were here it was raining and you forgot a red umbrella... I've been keeping it safe for you, hoping you'd return!" 20/10 service!

Why are people writing new editors when we already have the One True Editor? 😉
And while I'm being a grouchy old man, how can Emacs have been around for nearly half a century and people are writing new editors without adding the equivalent of M-x describe-function, M-x describe-key, and M-x where-is?!
