Random Musings of an Engineer
In an older post we looked at how SynthID hides a watermark inside AI-generated images. Today, let us look at text watermarking and how it works. This week Anthropic says Claude models will use a version of Google DeepMind’s SynthID-Text for all text it generates. So an LLM writes one token at a time.

A few months ago around CES, I wrote about Donut Lab’s “all-solid-state” battery. I was skeptical then, but wondered whether some surface-storage or capacitor-like mechanism could explain its claims. A lot has happened since then. So I owe it to whoever reads my posts an update on that. Donut commissioned Finland’s VTT institute to test [ ] The post Advanced Tech: Donut Lab Battery: Revisited…
There is a lot of buzz in this literal “space” about moving data centers into orbit. Space sounds cold, so it may seem like a cooling engineer’s dream. But I think this is one of the most misleading parts of the pitch. A processor converts almost all its electrical power into heat. A 1 MW [ ] The post Advanced Tech: Space Data Centers appeared first on The Tech Blog .
The protest in Jantar Mantar, Delhi, ended after Education Minister resigned. But internet shutdowns during the protest, followed by a Govt direction asking GitHub to remove opensource BitChat, concern me as a technologist. Privacy is a fundamental right in India, and personal communication cannot be held hostage to the whims of Govts. Alternate decentralized routes [ ] The post Tech Explained:…
Earlier this week, I watched a fascinating TechTechPotato deep dive on advanced lithography. I recommend it if you have the time. Researchers have explored X-ray lithography for more than five decades, yet it has never entered mainstream chip production. Let me try throwing some light there. Lithography transfers circuit patterns onto a light-sensitive resist on [ ] The post Advanced Tech: X-ray…
I was looking for a long-term rechargeable option for a few household gadgets. I knew 1.5 V lithium AA cells existed, but I had never used them till now. So I thought today was a good day to explain how they work. Lithium batteries in consideration are of two kinds. The first is primary lithium [ ] The post Tech Explained: Lithium AA cells appeared first on The Tech Blog .
If you are from India, you may have seen the e-rickshaw battery videos this week on how e-rickshaws are getting so called hacked disabled and India govt banning the vendor apps allowing for Battery Management System access. TBH its not even a hack. Its a safety feature to probably remote turn off BMS in [ ] The post Tech Explained: Bluetooth Exploits appeared first on The Tech Blog .
There has been a lot of hue and cry around AI data centers. I think a good part of it is valid, because big ones can stress the local power grid and water systems. The energy side is harder to solve as every calculation needs electricity. The water side is more interesting, because water is [ ] The post Tech Explained: Data Center Liquid Cooling appeared first on The Tech Blog .
There has been a lot of discussion around E20 fuel being rolled out across India. One side says it is cleaner and better for emissions. Another side says it hurts mileage. I wanted to look at the cleaner-fuel claim from a science point of view just for my understanding as there is lot of misinformation [ ] The post Tech Explained: E20 petrol appeared first on The Tech Blog .
Today, let’s discuss AMR sensors. These sensors are still relatively new to many embedded builders because you mostly find them in motors, steering systems, actuators and industrial encoders. I thought it is worth covering for newer folks. AMR means Anisotropic Magneto-Resistance. A thin magnetic film changes its resistance based on the direction of the magnetic [ ] The post Back to Basics: AMR…
