Next time management asks you to stack-rank the members of your team, buy an electrical motor assembly kit, drop it on their desk, and ask them to rank the parts by importance/performance.

"Trade Bibi for the hostages" - a sign held by a protester in Tel Aviv, and probably the most sensible policy proposal I've seen in a while.

The number of transistors on a high end GPU need to double twice more until you can buy more transistors in one GPU than Commodore sold in all Amigas ever sold.

The reason why McKinsey/MBA types like Sundar and his recruits ruin companies is that ultimately too much focus and belief in shareholder capitalism thinks that companies are devices that produce money.

But neither do employees go to work with the wish to produce money for their shareholders, nor do customers buy products with that intent.

Employees want to help the customers and get paid for that. Customers want the value of the product. Money to shareholders is a byproduct.

In an industry where stimulant use is rampant, I sometimes quipped "my experience with working with people on stimulants is that they revert to being 20 year old: attacking the wrong problem with immense energy, often missing the forest for the trees".

This paper seems to confirm my quip:

Downloading a YouTube video should be just as covered by "fair use" as recording a song from the radio onto cassette was.

Unfortunately, courts tend to continuously weaken society in the grand bargain between society and copyright holders.

A quick thread on the intensity of Israel's invasion of Gaza. Language about "precision strikes" can distract from understanding just how intense the aerial campaign was.

Strategic bombing of civilian infrastructure was a staple of the Allied WW2 strategy. The estimated death toll among the civilian population was 350k-500k, on a population of 80m, so about 0.4-0.6% over a period of 3 years.

If the Gaza death toll is ballpark accurate, 8000 deaths on 2m inhabitants is 0.4% in three weeks.

There's a lot of microservices hate, but there are also terrible balls of yarn. It reminds me that many orgs are not good at engineering.

A few rules that have served me well:

  1. architect your software, have a diagram.
  2. centralize responsibilities in the diagram.
  3. not every box in that diagram needs to be a service, some boxes should be shared libraries
  4. conversely, not every box should be a shared library

I heard something today that is reasonably profound in analyzing communication failures:

Having thought something isn't having said something. Having said something isn't being heard. Being heard isn't being understood. Being understood isn't agreement. Agreement isn't change. Change isn't permanent change.

Keeping this list of possible failure points in mind is helpful in analyzing communication failures.

"Updating your priors" is a fancy way to say "I changed my mind, but I'd like to sound mathy because I have the self-image of being rational - and difficulty accepting that I am a fearful angry hungry horny monkey with sophisticated sticks."

Today is my last day at Elastic. I'll take an extended break and focus on rest, family, health, writing, a bit of startup mentoring/investing, and some research - at least for a while.

I'm thankful for my great colleagues and my leadership at Elastic - y'all are stellar, even if I was often grumbly about some technical or architectural issues. ...

This is "highly targeted precision warfare". Don't be fooled, there's no such thing, and if y'all wait until the war is over to remove Bibi, the war will continue while he is alive.

Advertisement, but of the unpaid type: If you're a parent of a kid approaching 4-5, and you have a lot of cardboard (from stuff like Amazon deliveries or random other sources) -- buy https://make.do. It's pretty damn versatile, and offers a lot of playtime for money.

There's a German series of short stories where the villain is a McKinsey-alumni penguin that wants to turn the entire world into one big airport mall, and the loss of post-security entire hams feels like the villain progressed.

Over on the bird site, an account called @mbateman wrote about agency in education, and it struck a chord:

"Running teacher training about agency this week.
Nothing is more important than agency. But most people get agency wrong, especially educators who lean progressive.
Some haphazard calibrations:
Traditional education kills agency by removing choice and interest. ...

The person in front of me is an economist telling his neighbor, a pancreatic cancer drug researcher: How do you stay motivated to work on something so hopeless that the resources to do the research should be better spent elsewhere.

His job? Working for some investment fund.

A scholast in a largely political job telling a scientist that. Wow.

Dear neurodivergent Twitterverse, I suspect one of my kids might have/be ADHD. I am suspicious of self-assessment tests, and would like to learn more about the SotA for testing (ideally quantitative tests without practice effects). What outside of TOVA exists? Anyone with experience with any such tests?

Also: while I think it's unlikely, I'd be interested to see what reliable tests for neurodivergent traits exist that are for adults?
