evan_a_a··on Sandia National Labs SA3000 8085 CPU
Modern process nodes with smaller feature sizes are likely to fare far worse under radiation than the nodes of 25 years ago.

Additionally, total dose is only one part of the equation. Single Event Effects (SEE) also must be mitigated.

You can read NASA JPL's ASIC design guidance for a brief intro.

Yes, the Xilinx space grade devices are engineered and qualified for radiation tolerance. These are FPGA socs and share no heritage with AMD desktop and server processors.
evan_a_a··on Spain's Solar Is So Cheap Investors Are Looking for an Exit
This is an economic problem due to the poor level of interconnection between the Iberian Peninsula and the rest of Europe. It is also something that is actively being worked on. With better interconnection, renewable power could be more readily exported to the rest of Europe during peak generation, rather than ending up in the situation described currently where renwable generation is forced offline.

To my knowledge neither AMD nor Intel ship any processors that are rad hard or rad tolerant. For aerospace applications this is a very specific type of device which requires specific engineering work to achieve. You don't just get rad tolerant design through standard error correction and you definitely don't get rad hard without designing for it.
evan_a_a··on Credit cards are vulnerable to brute force kind attacks
I am a bit confused about your situation. Did you have a stolen card used to make a purchase at ebay that was not under your account? Or did you make a purchase at ebay and have an issue with the product you received?
evan_a_a··on Credit cards are vulnerable to brute force kind attacks
>As a consumer, I thought I was safe; when saving my credit card to a billion dollar valued european merchant, or when i purchase something from supermarket and ignore the receipt, but the reality is slightly different from that.

>I got the money back via chargeback in short time.

So as evidenced, you are protected by the fraud infrastructure. The bank ate the loss for the fraud and you were made whole. In the end, the banking system cares about fraud loss. And they are exceptionally good at finding the fraud. Making changes to the card payment system is extremely difficult, due to the vast scale of the systems, so without a very good justification that a particular change will move the needle on fraud rates, the banks will opt to not make the changes.

evan_a_a··on Cybersec is a thankless job: expanding workload and shrinking pay packet
>Even that ignores the fact that major corporations are frequently attacked by state actors, so really the minimum standard for protection against expected threats should include those as well, but I will leave that aside for now since the overwhelming sentiment is that protection against state actors is so utterly hopeless it is not even worth mentioning.

It always has been, it's just now the state actors are more and more active (and visibly so).

Pentests work to secure the product under test at the point in time of the test (if the company cares to fix the bugs...). The real solution is to design in security throughout the software lifecycle, not play pentest wack-a-mole game at the end of the cycle. If a pentester is finding trivial SQL injection in an app, then it is clear that the company never considered security. And unless the pentest makes them care, the cycle will just continue.
evan_a_a··on Cybersec is a thankless job: expanding workload and shrinking pay packet
It is an investment problem, they need to invest in security expertise, not security products and services. And that is the sad part, absent the company really caring to spend that money or an external demand (regulatory or customers) it just isn't going to happen. They'll just layer on more products and services and call it a day.
evan_a_a··on Cybersec is a thankless job: expanding workload and shrinking pay packet
The company I work for (consulting) upended the entire strategy to basically use pentests to sell managed services (XDR, NDR, SOC, vuln scanning, "continuous pentest") that does nothing to meaningfully move the needle on security. Which of course the market will buy, but it is incredibly demoralizing to see expertise sacrificed to the alter of recurring revenue.
evan_a_a··on Cybersec is a thankless job: expanding workload and shrinking pay packet
I forsee issues with really getting use out of any commodity language model in the hardware security context, because hardware systems notoriously lack standardization. And often times, the technical knowledge (datasheets, app notes) is locked behind vendor NDAs, or straight up not documented, only existing in the minds of engineers. The implementations of said designs are similarly highly proprietary, with little public "real" systems to train models on.

So the issue is two-fold:

* The knowledge must be documented and accessible for training.

* A bespoke model must be trained this documentation.

It is unlikely that both of these things happen in the general model context. Perhaps individual chip vendors will eventually pursue this, but I suspect it is just not a priority for them.

evan_a_a··on Cybersec is a thankless job: expanding workload and shrinking pay packet
I mean it in the sense that AI security hype and the larger geopolitical environment has woken up a lot of people to the reality that they need to consider security. And the ones that haven't woken up yet will get a wakeup call when they are breached. It also increases the demand for real security expertise, which is already scarce.

Also, in my niche (hardware and embedded product security), AI doesn't a have a functional impact to the work except in code analysis, but even that is difficult given the level of abstraction these systems are built at.

Whenever I tell people I work in computer security, their first question is "are you worried about AI taking your job"? To which I just laugh and respond "AI is job security"

evan_a_a··on Despite Doubts, Federal Cyber Experts Approved Microsoft Cloud Service
MS was (and still is it seems) unable to produce the data flow diagrams that FedRAMP wanted, ones that other cloud providers had no problem with. If the documentation is in such dire state, then the system itself is likely to also be in a dire state. I.e. The documentation is a pile of shit, so the system is also a pile of shit.
evan_a_a··on Grace Hopper's Revenge
>2) The Tesla section is interesting. I'm not saying that you are wrong, just that their methods have not produced the promised results yet

The flaw in Tesla's engineering choice to rely on a camera based system for self driving is that it is extremely difficult to approximate human vision with cameras alone. The author also does not mention this and instead assumes that "camera == human eye" which is not true.

>3) Wireless humanoid robots is a bad platform because we don't have the hardware to support them. Both battery density and compute efficiency is too low currently to support freestanding robots. Rip Roomba - long live its legacy

Boston Dynamics already has Atlas, with a 4 hour battery life and the ability to self-swap. That is already better than a human since it can presumably work non-stop for its entire runtime. Plus battery technology and compute efficiency are both still improving.

evan_a_a··on A lot of population numbers are fake
This is a literary device. The article continues to explain why this isn’t a simple problem, and it’s clear from the conclusion that the author understands the complexity.

>But it’s good to be reminded that we know a lot less about the world than we think. Much of our thinking about the world runs on a statistical edifice of extraordinary complexity, in which raw numbers—like population counts, but also many others—are only the most basic inputs. Thinking about the actual construction of these numbers is important, because it encourages us to have a healthy degree of epistemic humility about the world: we really know much less than we think.

evan_a_a··on Pavel Durov: "You'd have to be braindead to believe WhatsApp is secure in 2026"
He offers no proof, just “trust me bro”. If they actually had found flaws, they would’ve reported them. WhatsApp uses the Signal protocol, which is built by actual cryptographers using proper formal proofs. In contrast, MTProto is not designed from a formal cryptographic approach and is described by cryptographers as “brittle”. https://martinralbrecht.wordpress.com/2025/03/16/analysis-of...

Telegram also has no public security or cryptographic assessments, while meanwhile WhatsApp has had numerous components analyzed by cryptographers for security.
