jeffbee··on eMudhra intermediate CA compromise
I have no idea but I can imagine why you'd want to bias things away from principled randomness to avoid picking 0 or 4 or whatever.
jeffbee··on eMudhra intermediate CA compromise
When you have multiple selections you can show that the probability of selecting a set with a range much smaller than the population range is exponentially unlikely, strong evidence to reject the hypothesis that the subset was chosen at random. But when N=1 you can't conclude anything.
jeffbee··on eMudhra intermediate CA compromise
4 is as likely as any other randomly chosen number over a given range.
jeffbee··on Americans Are Spending More Money to Drive Worse Cars
It sounds like you are trying to back-construct the reality you want, that low electricity prices lead to higher fleet efficiency, but that's flawed. You should look at the reality on the ground. Washington actually has double the rate of pick-up trucks compared to California, higher than the national average.
jeffbee··on Agentic Monitoring
Yeah something about this whole concept is way, way off. The energy, and therefore cost, of an LLM analyzing every data point of every time series is many orders of magnitude too high, unless your operations are trivial.

High gas prices do persuade people. Look at the vehicle fleet in California compared to the other states. It is very different and the gas is only slightly more expensive.
jeffbee··on Go will reject certificate chains containing eight distrusted SPKIs
Clearly the platform isn't designed to do this. Nobody thought this was going to be a necessary facility. They have just crammed an array of numbers as literal values deep into the standard library. So clearly this is an exceptional event, and not the exercise of a feature that was foreseen.
jeffbee··on Go will reject certificate chains containing eight distrusted SPKIs
It's interesting that this sort of policy is baked into a language platform.
jeffbee··on Solar surpasses nuclear power globally for first time
For current technology it's 90% after 30 years.
jeffbee··on Solar surpasses nuclear power globally for first time
You can't really delay maintenance of steam turbines. You absolutely may delay maintenance of solar panels because they don't need any.
jeffbee··on Solar surpasses nuclear power globally for first time
That isn't even a very good rule. Look at the NREL panel aging data. Some of their panels are aging in reverse, producing more power after a accelerated aging treatment and years in the field.
jeffbee··on Solar surpasses nuclear power globally for first time
Brainwashed fission bros double-count reactor builds every year they are under construction. In terms of completed stations, China is opening 1 new reactor (~2GW) and hundreds of new PV stations (~300GW) per year. Over 99% of it is solar and nuclear is a sideshow.
jeffbee··on Solar surpasses nuclear power globally for first time
We absolutely have solved cheap battery storage. 100% solved. It is crazy to make this statement when we are discussing nuclear thermal power, which requires multiple 20-million-dollar steam turbines for every station. You should have said "We still haven't solved cheap superalloy fan blades".
jeffbee··on Solar surpasses nuclear power globally for first time
It is far more likely to run out of practical fissile materials than it would be to run out of electrochemical materials.
jeffbee··on Solar surpasses nuclear power globally for first time
Explain the mechanism by which you believe photovoltaic panels start failing.

Your concern would be valid for a nuclear thermal power station, a Goldberg machine with millions of moving parts. It is not really applicable to semiconductors.

jeffbee··on JPEG XL vs. AVIF for web use-cases
If anything the gap is worse on modern hardware because Lepton is hostile to both SIMD and divide-and-conquer thread parallelism.
jeffbee··on JPEG XL vs. AVIF for web use-cases
The main difference being that Lepton is worse and 100x slower.
jeffbee··on How gyroscopes got so small [video]
The more you listen to the details, the more irritating this video becomes, if you know anything. I guess ignorance really is bliss.
jeffbee··on I love software rendering
It should be pretty obvious that you don't need a Core 2 Duo to run Quake, which worked fine on a Pentium and some of the faster 486s.
jeffbee··on Google is silently linking your phone number across all signed-in accounts
"Silently" has been redefined to mean "we know this because of the emails it sends".
jeffbee··on Redesigning source control at Anthropic
I feel like "didn't scale well" is unfair to Perforce. It scaled to accommodate an absurd monorepo that might have been, at the moment they switched to Piper, the largest single software project in history. It scaled to handle the needs of every organization in the industry except Google and Microsoft.
jeffbee··on OpenAI engineer arrested in bugging of executive conference room
Right. I can guarantee that there are tens of thousands of listening devices with embedded radios in the OpenAI office, right now. The only open question is who controls them.
jeffbee··on Gemini 4 Argon
It sounds like the tool call is probably not grounded with your precise position.
jeffbee··on Turn a WiFi 7 Router into a 320Msps Software Defined Radio Receiver
You're referencing a 5-figure rig like the ADRV9040 I suppose? I don't work in that industry but I do dabble in SDR hobbies and I guess due to my advancing age I view this as linear progress rather than breakthroughs. Two decades ago it was $1 million worth of junk.
jeffbee··on Turn a WiFi 7 Router into a 320Msps Software Defined Radio Receiver
Why is this a breakthrough? Just because the platform costs under $100?
jeffbee··on Turn a WiFi 7 Router into a 320Msps Software Defined Radio Receiver
An accurate description is "turn an SDR into an SDR".
jeffbee··on Google Data Centers around the world
Not enough people to serve.
jeffbee··on Google Data Centers around the world
I was pretty obviously responding to the Australia part.
jeffbee··on Google Data Centers around the world
Nobody lives there. Ten times more people live in Indonesia.

That's enough that they can drive down to Central Computers and grab a 32GB stick.
