The "$60 Gaming PC" – AMD BC-250 (2025)
Ok it’s not exactly $60 but you can get the board itself for that amount of money on eBay if you’re lucky, but on average the price is around $70-$100 (as of November 2025) which is still very cheap considering you can play Cyberpunk 2077 on this.

I'm Getting into Mesh Networks (Meshtastic, MeshCore, and Reticulum)
I love networking, a lot. So much so that I've run my own ISP since 2024, complete with its own ASN, IPv4/6 address space, fiber optics, etc. However, do this and you quickly realize how reliant you still remain on central service providers. The internet is a mesh,

Intel Honesty
The best way to both save Intel and have leading edge manufacturing in the U.S. is to split the company, and for the U.S. government to pick up the bill via purchase guarantees.

There are no secure smartphones
Modern smartphones have a CPU chip, and a baseband chip which handles radio network communications (GSM/UMTS/LTE/etc.) This chip is connected to the CPU via DMA. Thus, unless an IOMMU is used, the baseband has full access to main memory, and can compromise it arbitrarily.

Discret 11, the French TV encryption of the 80s
I spent my childhood in France, playing a lot of soccer and watching way too much TV. In the 80s, there were three channels available. Two of them, Antenne 2 and FR3, were state funded and boring while TF1 was privatized and offered plenty of Japanese cartoons. My generation grew up with Captain Tsubasa, Saint Seiya…
