$220 is irrelevant to Google. The bot farms spend more. Hence, the small honest customer is not worth supporting when the large malicious customer will generate orders of magnitude more revenue. Viewed through the profit incentive, the e

No. DKIM signatures were designed to work when emails are forwarded. I run a couple of Linux related mailing lists, and the DKIM signature continues to validate specified headers and the body of the email when forwarded or resent via mail

Muscle memory and awful connectivity in remote places (well, not even that remote for me) is what so many GUI apps undervalue, and I don't think the author of the article has ever thought of or encountered this. I loved TUIs back in t

Every additional level of abstraction in computers has resulted in bloat that makes software less efficient and more bloated. AI is merely continuing to accelerate the tread. The real issue at hand is that humans need to decide to start re

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 and power). Parity bits are usually sufficient, as the purpo

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 $0.25/email for delivery, I'd be more than happy .

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 ISP for ~500 users before the network was disassembled last m

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 systems. Passing DMARC is not a signal that the 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 ultimately ended up regularly blocking a handful emails from c

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 years ago when processing VLAN tags and doing IP forwardi

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 device). Personally, I find it better to have multiple low end a

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 their AI models private in the face of interest by vi

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 for systems with a single NIC (virtually none of the systems

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 condemned to repeat it".

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 existence as a kernel developer at the time.

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 by software performing random reads off a disk. That&

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 SSDs and HDDs from a supply constrained supply c

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 now than ~25+ years ago. CPUs now have hardware features

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 volume production in 2028. It will include backside power del

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 slated for 2028, contingent on yield improvements.

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 time, I feel it was a great time to learn
