- Comment on Intel and AMD trusted enclaves, a foundation for network security, fall to physical attacks 2 days ago:
The communication channel between the main processor and the TPM is the easiest point of attack. The Chip Whisperer has been able to do this for years. Once someone gets their hands on the hardware, all bets are off.
Don’t see how this is new?
- Comment on In which ways the dot com craze of the late 90s and the current AI market differ? In which ways are the same phenomena? 3 days ago:
The unbridled enthusiasm is the same.
In the dotcom era, I had friends working at e-commerce startups selling items you could easily find at a store. They even had to buy from the same wholesale suppliers, and try to undersell retail, even though they had additional shipping cost (offset a little by not having to pay local sales tax). So they ate the losses because VCs told them they had to show the only metric was positive customer growth (not profit). All business ideas were “add e-commerce to X.”
In the 2008 crash, even though it was triggered by real-estate debt, a lot of the same tech dynamics were at play, except “add mobile to X.”
A lot of present day AI companies are following the same path. “Add AI to X.”
What’s different this time is that there’s a lot more hardware involved, in the form of GPU and data center expansion. After dotcom, we were left over with a lot of fiber, telco, and home internet expansion which was still usable. This time, it’s not clear what the data centers will be good for if AI crashes out. Maybe crypto-mining.

- Comment on Which career to pursue? 1 week ago:
A lot here. I have two suggestions:
- Create, then
- Share
Channel everything you want to do and is rattling around your brain into creation. It doesn’t have to be perfect. Nothing is. Get feedback from people you trust, then push them out without caring if anyone looks at it or reacts.
And keep learning. Especially things outside your comfort zone.
Eventually you’ll figure it out.

Have done it both ways. Will never go back to bare metal. Dependency hell forced multiple clean installs down to bootloader.
The only constant is change.
- Comment on 1 week ago:
The FT has used AI tools to identify these mentions of the technology in SEC 10-k filings and earnings transcripts, then to categorise each mention. The results were then checked and analysed to help draw a nuanced picture about what companies were saying to different audiences about the technology.
So… using AI to find out who is using AI and warn of underuse of AI.

- Comment on What Makes System Calls Expensive: A Linux Internals Deep Dive 2 weeks ago:
The next three steps in the code are:
-
Enabling IBRS (indirect branch restricted speculation)
-
Untraining the return stack buffer
-
Clearing the branch history buffer
These are there to mitigate against speculative execution attacks, such as spectre (v1 and v2), and retbleed. Speculative execution is an optimization in modern processors where they predict the outcome of branches in the code and speculatively execute instructions at the predicted path. When done accurately, this significantly improves the performance of the code.
It’s like one time someone came through your house and stole all the valuables from every room. Now you have to lock/unlock every single interior door as you walk from room to room.
This is why we can’t have nice things.

I’ve had my share of botched tech demos, so I can empathize. Steve Jobs, during an early iPhone demo legitimately blamed the Moscone Center wifi (I was there).
But this was just bad demo planning at every level. I’m sorry, but I couldn’t stop laughing.

Microsoft and Google both prototyped it. FWIW, they didn’t take it to production once the data was collected.
IIRC, cooling worked fine if placed in the right place with circulation, but maintenance and part replacement was a major issue.

- Comment on BBC - The people who hunt old TVs 3 weeks ago:
Most TV programs are broadcast in HD format. Especially sports. That was the main reason we got rid of our last CRT. The scoreboards were getting cut off at the edges. That, and the fact that the bottom right corner of the display had permanently faded to black.
- Comment on Frustratingly bad at self hosting. Can someone help me access LLMs on my rig from my phone 3 weeks ago:
Sounds like the issue is getting to the server, not the LLM server itself. If so, may want to look into running a reverse proxy, or if you want to access it remotely, tunnels: github.com/anderspitman/awesome-tunneling
- Comment on Just had a hospital group employee tell me to simply email medical information 3 weeks ago:
A long time ago I helped set it up so an elderly relative’s HOA dues were auto-withdrawn from their checking account. Someone stole one of their checks, washed it, wrote in a different name and amount, and cashed it. Bank anti-fraud caught it, refunded the money, and closed the account. I sent the HOA a message explaining the situation and asking what the procedure was to change account numbers.
They emailed over an attached PDF form. Had space for fullname, phone, address, bank routing and account number, and her real signature. Pretty much a PII nightmare. The instructions were to have it filled out and emailed back to them. 🤦🏻♂️
Told the relative to print it out and send it back by post.
- Comment on Alternative to github pages? 3 weeks ago:
AWS S3 lets you upload all content to a bucket, then mark it as a website. If usage is not too heavy, it can stay under the free tier.
But a favorite free one is Cloudflare pages: geeksforgeeks.org/…/deploying-static-website-to-c…
You can keep your content on github, connect it to a CF page, and have it auto-update on push to github.
