OpenMANET trades extreme battery life for a real LAN
OpenMANET uses Wi-Fi HaLow, 802.11s and batman-adv to build an IP network without infrastructure. More bandwidth comes with a very different trade-off from LoRa.

This firmware was not dumped. It was rebuilt from what the CPU read
Matthew Alt reconstructs a firmware image by observing SPI reads during boot. Each transaction reveals an address and bytes, while any region the CPU never requests remains unknown.
This titanium cube floats. Its bulk density explains almost nothing
RMIT makes a titanium lattice float while leaving its large cells open. The trick lies inside the hollow struts, and in choosing the right density to count.
A robot builds a laser, then realigns it when you knock it out
At MIT, a robot assembles ten optical components, corrects placement errors and restores laser alignment after a disturbance.
Cloudflare wants to compress its cache once, not recompress the Internet on every request
Cache Transcoding stores some text objects as zstd inside the cache, keeps them compressed between data centers, then decodes them at the edge. The bet is to spend a little CPU to buy much more effective cache.
MIT builds the photonic chip on silicon, then removes almost all the silicon
The process keeps the wafer rigid through the steps that need precision and foundry tooling, then removes the original support and transfers the optical layers onto transparent film. Flexibility arrives at the end.
The report says 94%. The signature says it ran. Don't mix the two.
K-Veritas ties commands, metrics and report into a signed trace you can verify without rerunning the experiment. The signature proves less than the project implies — that is what makes it interesting.
Three years after Intel's promise, glass chip substrates still have no commercial product
Glass-core substrates were meant to replace organic packaging after Intel's 2023 announcement. Three years on, they are only entering package qualification, and the first product keeps slipping.
Draw on a wall with a laser that never actually touches it
Laser Graffiti runs in the browser and paints on a wall from a laser pointer. Behind the gimmick: calibration across camera, projector and surface, plus a neat feedback problem.
He can't write Verilog. His chip is chasing real silicon anyway.
Ken Chang admits he cannot write Verilog, yet an AI co-wrote a handwritten-digit classifier that is heading for a TinyTapeout shuttle. Everything checks out in simulation; the foundry remains the real test.
