It's not about "fairness in women's sports" any more than it was about "ethics in gaming journalism."

I just implemented my own left-pad function for key processing. I find this need particularly hilarious given the history of left-pad functions.

Curl has added experimental support for HTTP Message Signatures (RFC9421) in the next release! daniel.haxx.se/blog/2026/07...

Mitch McConnell hasn’t been seen or heard from in 6 weeks(!) in the hospital. Yet he still has a job, still getting paid, and getting unlimited world class healthcare. The man who voted against a living wage, against universal healthcare, and against guaranteed paid leave—is now getting all three.

Good grief, this hits home.

lots of reporters suddenly worried about slipping into communism but strangely f*cking quiet about slipping into fascism

The two ICE agents who murdered a civilian in Biddeford, Maine today. Let's make them famous.

Just 10 people have already poured $617 MILLION into this year’s midterm elections. In the entire 2008 presidential cycle, the last election before Citizens United, total billionaire spending was $16 million. This is not sustainable. We need to get Big Money out of our democracy.

Just a reminder that the US Woman’s team has won the World Cup four times already.

Dozey Don went to the trouble of actually creating a chart to compare the length of the Reflecting Pool to the height of 3 various skyscrapers, for some reason known only to him. Towering over ALL of them is, of course, the #EPSTEIN_Files. #TheMidtermsCantComeSoonEnough

Merriam-Webster’s human editors have chosen ‘slop’ as the 2025 Word of the Year.

A new small update to mkjwk.org, thanks to some folks from the community. A couple small bugs were fixed, plus you can now copy and save a key configuration as a URL that you can pass around. This doesn't copy your key values, but it does set all the generator's parameters.

All righty, we got the all clear this time. Follow Dan as he explores the "cost" of a Desert Bus:

Wooo, I won some dice! Maybe I'll try that dungeons and dragons thing I keep hearing about.

"There's a there there." #ietf124 Lots of enthusiasm and positivity (and advice from experienced folks) for forming an #atproto WG at @ietf.org We had 130 people on the stream and a very active chat. Great job @bnewbold.net and @dholms.xyz and everyone else. Thank you all for showing up! 👏

How do you end up confused and wildly variable about your disposition towards a President... in their second term? Come on brah Brah ur killin me here Ur killin us

Dear literally every company but mostly Zoom right now: I do not want your AI chatbot, and I especially do not want it taking up 1/3 of my window space to the detriment of everything I use your app for. I don't want tips for icebreakers, I want to have my meeting.

Freedom from kings. Freedom from fascism. Power to the people forever. ♥️ Happy Independence Day 🇺🇸
