how do you make workflows not suck as a team gets bigger it's just easier when people have access to things. but then there's risk with people having access to things i hate when people get blocked because they have to ask someone to do something, this is 10x worse now that we have agents
Came across this fantastic post by Slava Shestopalov randomly while looking for something else medium.com/design-bridg... In the usability & web tech class we used to teach at MIT with @karger.bsky.social I’d give a lecture on graphic design that included this, but this is so much better presented.

If anyone can suggest a good "how I used Prime Agent" article, that might help me to understand whether to try it. I agree that an IPython REPL has better properties than a stream of markdown. I want to see how that compounds into a different user experience.
right now i’ve got it setting up SQL Server on Mac, and it’s written a whole set of helper functions & classes to rerun various tasks “code is liquid” Prime Agent is the full recognition of that statement
i think Prime Agent is likely a watershed moment, there’s a ton of overhang captured just by a better harness RLMs aren’t new, but no one’s made a coding agent based on RLMs for big problems, it seems likely that the ReACT pattern has been replaced by RLM

There’s something like a “responsibilities treadmill” in middle-age where if the quantity of your responsibilities increases by 75% and you maintain a 85% completion ratio you have the same feeling of falling short even though you got done 75% more.
Some initial thoughts, and a complicated mix of feelings. Wow. I mean, Erdos problems are cool (I genuinely mean that), I didn't know about the Jacobian conjecture before it got disproved. But this newest batch from OpenAI hits home in a way the previous announcements did not.
I promise I was looking for the share button before I realized you linked my post @mcmullarkey.bsky.social I really liked this one. Provocative! buttondown.com/datadash/arc...

On helpful parenting tip I discovered during covid is that a new lego set is always cheaper per hour than childcare.
I’ve been sent this lovely chart showing nested synonyms for popular adjectives without a source. Still worth sharing. I love it!
As a person who has lived in both Fahrenheit is simply superior. It’s finer grained and saying “three digit temperatures” accurately describes The Horror. The trade off of having freezing point be a big round number just isn’t worth the compressed scale
i will accept universal greenwich mean time if the rest of the world admits that celsius is a stupid way to measure temperature
Here @fil.rezo.net reproduces @climatecasino.net’s chart, using warped gridlines to represent both the absolute temperature and the deviation from the historical mean for each day of the year. new.observablehq.com/@fil/godzill...

I always liked Ben Evans. this is an especially good example of what a good version of Zitron's analysis would look like: axes of variation, how they could play out, this or that is more likely. as opposed to "I'm certain what will happen next despite having been wrong every day for three years"

The love that professors I follow on here are showing student 22 in the comments is so heartwarming. Something I hope college students can internalize is how much love there is in the academy for student 22.

Kyle (couldn’t find his bluesky acct) is grieving the flow state coding used to give him. I’m hearing this a lot, but not universally. Has anyone found good ways to use AI but achieve flow? www.tiktok.com/t/ZTSHq2ucE/
AI has stolen the parts of the job that allowed me to get into flow state. Has it done that for you too? #AI #softwareengineer
