I feel like linear has finally given us a quality project management web application. Now they need to raise a huge round to fund training for the entire tech industry to learn how to run projects in a way that is not a chaotic confusing shitshow.

Kagi Translate is now available as an app for Android and iOS! From the makers of the best search engine around (@kagi.com).
Probably better than DeepL, definitely better than Google Translate. Way better. Good riddance, Google Translate.

Really thinking of putting together an ATProto for Scientists post explaining why the work that is being done in the ATProto community benefits their work. I want to scream from the rooftops on how cool this platform is.

This looks cool; great to give people more expressive spaces to publish and foster communities…

Youtube should mandate a banner on all videos mentioning supplements and vitamins that says "Supplements and vitamins are often over consumed. Consult your doctor for a blood test to determine if you need additional supplements or vitamins before taking anything advertised to you"

What I love about ATProto is the shear commitment to a common goal that developers on the platform have. I haven’t enjoyed a development community as much as this one!

Some alternatives:

My life hack for git is to use a good gui client. Idk what else it does now a days, but it does a great job showing me what the history looks like, conflicts during rebases, and just over all visualization of a git repo
I believe it’s free for open source and local repos. But it’s worth the sub

Spent the last day teaching Git and OOP fundamentals to software scientists and it is so cool to get to share the practice of software engineering. It is more than just "coding" but more about how we write code and how we communicate with each other to build better software. Very grateful for it!
