Deaths per terawatt-hour of nuclear is still lower than any fossil fuel per https://ourworldindata.org/grapher/death-rates-from-energy-p...

ECC tends to be too expensive to be used widely in hardware data paths. Most of the time hardware will use a parity bit as checking it is far less costly (both in terms of gates an…

Exactly this. Spammers have the technical competence to overcome any technical hurdle, so using evidence of technical competence achieves nothing. If it were possible to charge $0.…

It works at small scale when you self-select for technical competency. It does not work at larger scale when that self selection is no longer possible. My scale is that I ran an IS…

Then you don't deal with email in the real world. DMARC prevents legitimate emails from people in the real world from being delivered because people make mistakes with their email …

Sadly the article doesn't really touch on whether or not DMARC accomplishes anything truly useful. When I enabled DMARC for ingress email on one of my own mail servers, it ultimate…

It's easy enough to write a bit of Verilog to perform partial updates on the CRC to only compensate for what has changed. I did so for an FPGA project I implemented a number of yea…

The U7 Lite only does 2x2 MIMO. Compared to 4x4 MIMO in the U6 LR, the U7 Lite therefore does a much poorer job at beamforming (directing the energy of the signal towards the devic…

What precisely is the moat surrounding AI that SpaceX is using to justify this kind of spending spree? I don't how SpaceX and other AI companies will be able to keep the weights of…

The US' ongoing hostility towards Canada is decimating the relationship. The auto sector chaos inflicted by the US has destroyed decades of cross-border integration that benefited …

Postfix has a far better security track record. Exim has a steady stream of CVEs.

Personally, I find the predictable network names feature infuriating 100% of the time. Changing the name of network interfaces made nothing better, and actively made things worse f…

All you need are NAND gates.

McDonalds actually seems to have learned to take latency seriously. When their touch screen ordering systems were first deployed, the delay between tapping on an item or button was…

BitKeeper tried to do that. Git was built because the commercial license of BitKeeper became unworkable for the Linux kernel community. "Those who cannot remember the past are cond…

There were more ~26+ years ago. gcc and egcs had some subtle register allocator bugs that would get tripped up under heavy register pressure on i386 that were the bane of my existe…

Please name a computer science program that has an ethics component. Yes, I wish software developers were more like actual engineers in this regard.

Software was already far down the bloat path by the time the Core 2 Duo came out, so the upgrade didn't make all that much of a difference in feel given how much latency was caused…

Many of the merge lanes in California are insanely short compared to those in the rest of the world. The worst are the ones that have merge immediately before an overpass and exit …

It's plausible that the AI companies have given up storing data for training runs and just stream it off the Internet directly now. It's probably cheaper to stream than buying more…

Given the tectonic shift in priorities for Linux kernel development over the past decade, I'm willing to bet that many key developers would be open to a microkernel architecture no…

To make things even more confusing, the high-density floppy introduced on the Amiga 3000 stored 1760 KiB

Please read the article in full. The GPU die where all the computations occur and the majority of power is spent will remain on TSMC. TSMC plans their A14 process to be in high vol…

The entire sentence is even less enthusiastic: "The GPU die will remain with TSMC, but portions of the I/O die are expected to leverage Intel's 18A or the planned 14A process slate…

Thanks for publishing your blog! The articles are quite enlightening, and it's interesting to see how semiconductors evolved in the '70s, '80s and '90s. Having grown up in this tim…
