AI efficiency is important. The median Gemini Apps text prompt in May 2025 used 0.24 Wh of energy (<9 seconds of TV watching) & 0.26 mL (~5 drops) of water. Over 12 months, we reduced the energy footprint of a median text prompt 33x, while improving quality:

If there were a single lesson I'd drill into new software engineers it'd be this:
You can be technically right and politically and systemically dead wrong.

"People falling asleep in meetings due to exhaustion aren’t sent home to rest — they’re praised for their "extreme ownership" and dedication. Knowledge sharing and documentation get deprioritized against building. Testing is skipped because it harms velocity and extends timelines."
Silicon Valley's most extreme work practices get exported globally as "best practices" while sustainable approaches stay invisible.
On a recent work trip, I met people who'd absorbed a vision of Silicon Valley culture that bore little resemblance to reality.

A Borges story about a guy who gets AI to summarize all the world’s information for him, and then summarize the summary, until the AI has the whole world summarized into a single word. He sits alone at his desk, staring at the word, repeating it endlessly, certain he is experiencing everything

[comments progress along the line, approximately every 3 digits] (1) 54! Great! I know that number. Solid start. (2) Oh, a comma and some zeros. Cool. Must be at least 54 thousand. (3) A second comma! I wonder if we’re talking population or money. (4) Yikes! If this is money, it’s a *lot* of money. (5) Why am I reading this? Whatever this number is, I’m not going to be able to visualize it. (6) All right, either someone made a unit conversion error or this is one of those incomprehensible astronomy numbers. (7) [4 zeroes between commas instead of 3]] Oh no. Is this a misplaced comma or an extra zero? I guess we’ll see if the next group has two zeros or three. If it’s two, we can at least hope the digits are right. (8) [4 zeroes between commas] Oh *no*. (9) [repeat of the digits 54] What is happening. (10) [a quotation mark in place of comma] Someone messed up real bad. (11) [final digits are c2ef46, cut off] Someone messed up real bad and I hope it wasn’t me.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cz73r7iyiqn26upot4jtjdhk/bafkreih3hirktm65hdw44t573arldaizpyect42tpkiochyewbagbj5gh4@jpeg)

Flutter's dev tools are from another planet.

- Extract to widgets and add state with code mods
- Generated labels for what each `}` corresponds to
Oh, and did I say hot reloading? What a way to build desktop apps ❤️

Job interview for my current position included "what happens when you type something into a browser address bar" and they literally had to tell me to stop.
One of my crazy complex job interview questions for very technical people is "what happens when a file gets opened." It's pretty easy for that question to wind up filling the hour without even getting super deep into like the exact on disk formats of different filesystems.

Bloom filters seem like a good data structure to make lock-free for concurrent access: you can use an atomic fetch-and-bitwise-OR instruction for writes
Benchmarked this thing with a realistic read/write load in a test and high concurrency (10k adds/sec on one routine, 7 additional concurrent routines testing as fast as possible).
v.s. a naive RWMutex implementation on a 8c16t test box it was ~14x faster (~14M tests/sec)

Implemented two-pass GPU occlusion culling (using a hierarchical depth buffer - "HiZ") in my SDF engine!
The video shows disocclusions (bricks that need to be rendered in the 2nd pass) in pink. This technique reduces the number of bricks rendered by 50-90+%.
More details below.

Eventually you reach an age where your story is so beyond telling you just live with it, quiet. And there is confidence in this. They don't know you, and they can't. You've lived longer than being an archetype. You can't be hated, but you also can't be loved.
You just have to sit there, and live.
