edgineer··on Piracy Operator Goes from Jail to Getting Hired by a Tech Unicorn in a Month

edgineer··on Used EVs have never been cheaper. But are they a good deal?
Maybe it's worse with ICE cars--more parts, many considered wear items, that are difficult to get to to inspect. It could be hard to tell if the seller recently changed the oil and filters after never changing them. Transmission, alternator, etc. could have issues only intermittently.

Should be easy to see HV battery health, charge to 100% and check remaining range reported. Drive unit/other battery issues seem pretty rare and I'm not sure they're correlated with driving behavior, though I could be wrong.

edgineer··on Used EVs have never been cheaper. But are they a good deal?
I'm satisfied with the flat fee system. The cost difference is at most $150 per car per year, which is not much to argue over. It is more like eating into the savings from switching from gas to electricity, rather than an additional burden.

The premise of being taxed by mile driven is arguable. People benefit from roads even when they do not drive. AFAIU light passenger traffic has little bearing on the resultant maintenance costs, that most wear comes from heavy trucks.

I do not want separate meters complicating EV charging and accounting.

Is this not an oxymoron? E.g. b3 then ought to be an order of magnitude easier to brute force.

edgineer··on CT scans of 1k lithium-ion batteries show quality risks in inexpensive cells
I went to vapcell's website, looked at their charts and specifications. I disagree with your assessment.

They specify 3800mAh minimum discharge at 0.2C for their 4000mAh cell. They don't show a discharge curve at 0.2C in their charts (would be 0.8A) but they do have a 1A discharge. When the 1A discharge curve reaches 3V, the energy discharged is right around 3800mAh.

Lumafield discharged at 0.2C, and they saw only 3055mAh.

Vapcell's site mostly shows high current discharge curves, where yes there is more capacity below 3V available, but with Li-ion at lower currents, the curve is very steep past 3V, not much more capacity left after that. And when you're discharging at high current you won't expect to get the full capacity, anyway.

I'll also take this time to point out lygte-info which is a treasure trove of battery tests.

edgineer··on LaLiga's Anti-Piracy Crackdown Triggers Widespread Internet Disruptions in Spain
I'm interested in hearing more about the evolution of copyright law wrt computer media in Spain. I see an article from 2001 describing how compiled software was not copyrightable in Spain at that time. [0] From [1] I see that individual file sharing, except for software, is allowed there.

Having seen how Sweden changed their copyright law in response to the Pirate Bay website [2], I wish everyone knew that it wasn't always this way, and that states maintain their own rules. The idea that "no one shall copy any corporation's media, ever" is a recent propaganda success.

edgineer··on About the security content of iOS 15.8.5 and iPadOS 15.8.5
My Pixel XL here works great for scrolling at night. I'm skeptical of the "no more system updates" boogeyman; I'd love some case studies or anecdotes about the real-world threats that using an old devices exposes me to.

edgineer··on FBI cyber cop: Salt Typhoon pwned 'nearly every American'
Not sure if you're aware, but the organ harvesting allegations are complicated because the Falun Gong believe their adherents enjoy magical organ healing; the blind will see, kidneys become good again, etc., and that they are targeted specifically for their organs is an endorsement of their religion. So there's incentive for false claims, which I rarely see brought up.
edgineer··on GMP damaging Zen 5 CPUs?
"boost up to max temp and stay there"

At stock settings CPUs will boost depending on many factors. Once one of several different limits is hit the CPU will not boost as high, trying to find a steady state where it stays below Tjmax.

Note the following: the 9950x does not come with a stock cooler. AMD recommends water cooling for the 9950x. Transistor lifetime decreases exponentially with temperature.

I'd expect that a 9950x under sustained load paired with a "165W" cooler would not only not boost, but would throttle to below base clocks.

In the case of CPU cooling, I don't agree that relying on the CPU's thermal safety nets to continuously regulate the system to avoid damage is good practice. With additional cooling to ensure it never reaches Tjmax, this also will result in better CPU performance, a tangible benefit.

Had the author monitored his systems, he would have observed high temperature and throttling. Yes, in 2025 it's arguable that a CPU's safety net should be reliable wrt temperature, even if you run with no heatsink at all. I also agree that TDP specifications are unclear.

But the bottom line is that you should pay the extra $100 or so to cool your CPU properly. It will be faster and more reliable.

Please take care of your equipment; do not take it for granted.

The Tesla crash in the story you linked to didn't involve FSD, blinding, nor disengagement. Did you mean to link to a different article?
edgineer··on Elon Musk is lying about Tesla's self-driving and I have the DMs to prove it
If one or more of the multiple cameras are obscured, the car will alert you to the degraded state. If conditions are particularly bad like in a snowstorm, FSD will refuse to engage. It doesn't drive blind.

"We don't overclock or overvolt or play other teen games with our hardware."

You overclock as a teen so that as an adult you know to verify your CPU's voltage, clock speeds, and temperature at a minimum when you build your own system.

They made no mention of monitoring of CPU temperature, ECC corrected/detected errors, or throttling. They then ran CPU benchmark loads for several months on the system.

"The so-called TDP of the Ryzen 9950X is 170W. The used heat sinks are specified to dissipate 165W, so that seems tight."

Yikes. You need a heatsink rated much higher. These CPUs were overheated for months.

edgineer··on Framework Laptop 16
I'm very happy to see Framework lead the USB power delivery pack by supporting 240W, 48V/5A charging on the Framework 16. As the first company to ship laptops using this spec, what problems or quirks, if any, have you seen from 48V charging in the field?
edgineer··on Retailers slash prices of AMD and Intel latest EPYC and Xeon CPUs by up to 50%
I noticed today that a 9175F was in the $2000s down from a $4000s MSRP. I still can't justify buying one when a 9950x3d is more performant and <1/3rd price, even though the epyc has more PCIe lanes.

It's my first time contemplating getting a server CPU, so I assumed the insane markups were the same story as with Lenovo laptops, or Advance Auto parts or McDonald's meals--that nobody pays those prices, unless you're a sucker.

edgineer··on Starbucks in Korea asks customers to stop bringing in printers/desktop computers
External monitor, keyboard, mouse, sound, stuck in closet and used as a NAS... I do all these with laptops just as much as with desktops.

Laptop price disadvantage can even flip when buying used due to cheaper shipping.

Laptops can't hold as many internal devices nor the fastest parts and have worse thermals/sound though.

The founder started that he was not interested in serving users who want anonymity. I see they've since added Privacy Pass using VOPRF tokens, which does provide anonymity by decoupling searches from user accounts. But by now LLM search tools are good and don't require an account.

edgineer··on Kioxia LC9 SSD Hits 245.76TB of Capacity in a Single Drive
Another era of drive capacity, another increase in dec/bin unit deviation. 1 PB = 0.888 PiB. So 0.873 PiB with four of these drives.

I'm glad this flyer at least uses KiB; you'll see drive spec sheets with base-2 "KB" and "MB" but base-10 GB and TB.

But with another prefix transition I'm once again hoping us consumers can get GiB/TiB/PiB values up front.
