Show HN: Capn-hook for coding agents – don't grep the same mystery twice
The monitoring agent that cannot be told what to do
Here is a design decision we made early, wrote into the architecture as an invariant, and have refused to revisit since: our agent accepts no commands. Not "we don't currently use that feature" — the hub has no way to tell an installed agent to do anything at all. No remote execution, no self-update, no "collect this for us right now". It sends data outward, and that is the entire surface. This is not a limitation we are working around. It is the product. And it costs us features that customers ask for, which is exactly why it is worth explaining. The uncomfortable arithmetic of remote control Any tool that can update a plugin across fifty client sites is, by construction, a tool that can execute code on fifty client sites. Any dashboard that can restart a service on your server holds, somewhere, a credential that lets it in. This is not a flaw in those products — it is what they are for. You cannot automate a repair without the power to perform it. But that power has an owner, and the owner has a login, and the login has a support team, and somewhere in that chain there is a version of the software with a bug in it. When the tool is compromised, the blast radius is not the tool. It is every machine the tool could reach. The industry has already run this experiment at scale. In July 2021, attackers exploited a vulnerability in a widely used remote monitoring and management platform. They did not break into a single company — they broke into the thing that had access to the companies. Roughly sixty managed service providers were hit, and through them, an estimated 800 to 1,500 downstream businesses were encrypted in a single weekend, with a $70 million ransom demand attached. Read that shape again, because it is the whole argument: the victims did nothing wrong. They had bought a well-known product from a serious vendor and installed it exactly as instructed. Their compromise arrived through the door they had deliberately, sensibly, contractually left open — the one

The First Microcontroller Was the TI TMS1000 (1974)
Ask most people to name the chip that started modern electronics and they will say the microprocessor. But there is a quieter hero inside almost everything you own that beeps, blinks, or connects to the internet: the microcontroller. And the first one you could actually buy shipped in 1974 as the Texas Instruments TMS1000. Microprocessor vs. microcontroller The distinction matters. A microprocessor, like Intel's famous 4004, is just the processing core. To build anything useful with it you still have to wire up separate memory chips, input/output controllers, and support logic on a circuit board. A microcontroller collapses all of that onto a single piece of silicon: the CPU, the ROM that holds your program, the RAM that holds your data, and the I/O pins that talk to the outside world, all in one package. That is exactly what the TMS1000 did. Designed by Texas Instruments engineers Gary Boone and Michael Cochran, it was a 4-bit device using a Harvard architecture, meaning it kept program memory and data memory in separate spaces so it could fetch an instruction and read data at the same time. One chip in, one chip out, and you had a complete tiny computer dedicated to a single job. Cheap enough to put in everything The genius of the TMS1000 was not raw power, it was economics. In 1974 you could buy the chips in volume for around two dollars each. By 1979, Texas Instruments was selling roughly 26 million of them every year. That price point changed what engineers could build. Suddenly it made sense to drop a small, programmable brain into products that never would have justified a full computer. You have almost certainly held one. The TMS1000 family ran the Speak & Spell, the Big Trak programmable toy vehicle, and the electronic memory game Simon, along with countless calculators, microwave ovens, and appliances. Each one was doing the same fundamental thing an IoT node does today: read some inputs, run a fixed program, drive some outputs. Why this still matters for

Lorde says Ray-Ban Meta AI glasses are ‘not sexy’
Lorde was performing at the Real Cool Festival in Madrid on Thursday and took some time during her set to speak out against AI glasses. While she didn't specify any brands in particular, it's likely she was taking a shot at festival sponsor Ray-Ban, which has collaborated with Meta on a pair of AI smartglasses. […]
