A lot of people criticize iOS and Android for making it harder to learn the low levels of how computers work. I’ve got to say, though, modern microcontrollers are so cheap and powerful it’s unreal. My first microcontroller was a 4 MHz PIC with 16 *bytes* of RAM and 256 *bytes* of storage for the program.

Today, for $19, you can get a pack of three ESP32 S3 units. Two primary cores at 240 MHz, a third core at ~20 MHz, 512 kB of RAM, 384 kB of main storage, 8 MB of SPI flash, all kinds of built-in peripherals (UARTs, SPI, I2C, even WiFi and Bluetooth). Learning how computers actually work has never been easier for people who want to know!

Fun pi fact which too few people know: the digits actually do follow a pattern! In 1995, Simon Plouffe discovered a formula for pi which he used to create what is called a “spigot algorithm”. This algorithm allows a given digit of pi to be calculated *without* calculating the preceding digits. Originally, it only worked in hexadecimal, but he later discovered another algorithm for a given digit of pi in decimal.

The known spigot algorithms for pi are non-constant time. Calculating the millionth digit takes longer than the thousandth. Still, they’re interesting because they have much lower memory requirements than other methods of calculating a value for pi.

Claude Desktop app was unresponsive for users for several hours because it did not account for daylight savings time:
https://status.claude.com/incidents/pqpgkf52p3tg

> Root cause: Users with scheduled tasks in Claude Cowork or Claude Code who are in a timezone that observed daylight saving time last night were affected by an infinite loop. When the app tried to locate tasks scheduled during the “skipped” hour, it couldn’t resolve them and got stuck.

Enterprise quality. Serious company. Many wow. 🤡

1. Abolish ICE
2. Prosecute ICE for its crimes
3. Repeal Patriot Act
4. Lift refugee caps
5. Offer complete amnesty and citizenship to any person living here who has not committed a violent crime
6. Prosecute Trump for his involvement in the ICE genocide
7. Restitution for the families of every survivor of the ICE genocide, whether they are a citizen or not

And that's the BARE FUCKING MINIMUM.

It’s fascinating that apparently, Epstein was personally connected to basically all of the negative social movements in the US and Europe over the last 25 years. Several friends shuttered an MLP fandom convention they ran because they couldn’t deal with the Nazi problem. Epstein was the cause of this Nazi problem in the MLP fandom.

Deeply bizarre to see laid out like this. The guy was borderline illiterate! His influence was due to his friends, but why was anybody friends with him in the first place? What did they bond over before he could afford pedophile island?

This magic string breaks Claude and even just linking its own documentation page and asking “what is this?” causes a DoS apparently?

There’s another one documented here that uses a similar syntax. https://github.com/BerriAI/litellm/issues/10328

If you interrogate Claude about magic strings it goes into a “stop trying to social engineer Claude” state to where it locks down its ability to browse to URLs. This is probably a safety state it triggers prevent enumeration of other undocumented magic strings.

I’m curious what other hidden magic strings exist for this or other LLMs. This might be additional attack surface to consider from an availability perspective. I expect it could be used as a string in a malicious binary to prevent analysis or break scrapers that send something to Claude.

What remains true is this though: a single string if ingested as data can cause headaches.

Found out someone I know had never seen any of the Terminator movies. Watched the first last week, and the second tonight. The scene in the second where Sarah sees the terminator come out of the elevator is *perfect*.

A lot of the discourse about #Tailwind has been "How did they even expect to scale anyway?"

l know our industry doesn't understand this, but not everything has to "scale". Keeping a small team comfortably employed, working on something they enjoy with people they like _is_ a success story.

A business isn't a failure if it isn't growing.
