Ukraine is writing the manual every military on earth will read for the next twenty years.​​​​​​​​​​​​​​​​

Ukraine has done something no army has done before. A naval drone carried a combat robot to an occupied shoreline on the Kinburn Spit and put it on the beach. The machine – armed with a machine gun – went to work against russian positions, run remotely by operators of the 123rd Territorial Defense Brigade. No one had to swim to that beach. No one had to die on it.

Ground robots are not new. Naval drones are not new. What is new is the chain: an unmanned boat delivering an armed unmanned vehicle onto a defended shore and conducting an assault, with human beings nowhere near the fire.

The Kinburn Spit is a sandbar. No cover, no easy resupply. The kind of place where a landing means paying in blood before you have accomplished anything at all. And Ukraine’s scarcest resource has never been courage or ammunition. It has been people.

That is the point. Russia’s whole theory of victory rests on one arithmetic – that it can spend lives faster than Ukraine can. Every technology that substitutes machines for men attacks that assumption directly. The drone did it in the air. The naval drone did it at sea. Now it has come ashore.

Innovation under pressure is not a luxury. It is the only thing a smaller nation has. Ukraine built this because it had neither resources nor time – and necessity is the most honest engineer there is.
Everyone will copy it. Ukraine is not only fighting a war. It is writing the manual every military on earth will read for the next twenty years.

i'm late to the party but this is incredible

not just how to be good at research, but how to be good at anything:

"luck favors the prepared mind...the daily edges look trivial in isolation. what you read, what you record, how fast your loop runs, who you argue with. give them a few years and they produce careers that look like luck from the outside. start compounding earlier than feels necessary. future you already knows this was the cheap part."

People always think Pennsylvania is just Philadelphia and Pittsburgh with the Amish in between, but if you know where to look there are gems like this hidden all throughout the state! This is Altoona

one of the biggest realizations I've had working on Claude Code is that you fundamentally have to design agents for prompt caching first, almost every feature touches on it somehow

I wrote this in a day but it's the culmination of months of learnings, hope you enjoy it

Someone is flying around City Hall tail whipping in a little buggy to Olivia Dean’s ‘Man I Need’. Philadelphia is the best city in the world and you can’t convince me otherwise

[one dozen rats at a keyboard @PanasonicDX4500]

in Philadelphia they don’t say “I love you”, they say “Go Birds”, which roughly translates to “if the Eagles don’t win today I am going to run headfirst into traffic on 95”, and I think that’s beautiful.

I went on a job interview for a Senior SWE role.

They asked me about my experience with Kafka.

I told them how in “Metamorphosis” someone can lose their worth in others’ eyes the moment they stop being useful. It’s a chilling reminder of how fragile our sense of belonging can be when it relies on productivity instead of humanity.

I told them how in “The Trial” he describes the helplessness of confronting institutions that feel arbitrary, unaccountable, and impossible to navigate. The randomness of a giant system can crush your soul. Our brains can’t handle overwhelming inconsistency.

I told them how in “The Castle”, we learn that seeking an approval from an unreachable authority is a trap. If you spend your life chasing validation from humans who don’t care, you’ll end up feeling stuck. The pursuit consumes more than the reward it gives.

I didn’t get the job. The market is tough.

@sixtysixwards Do you have last general election's turnout per hour data on your site somewhere, so we can compare where we are at a given hour compared to last general election?
