Energy recovery is absolutely possible. On a smaller scale, all jet airliners have a RAT (Ram Air Turbine), which is just a propeller that drops into the airstream if both engines fail. It provides hydraulic pressure and electrical power du

It is trivial to serve different javascript to different clients on a request by request basis, making it very unlikely that highly targeted malicious js will be detected. Most thick client update mechanisms make this more difficult (but ce

I ran Debian on my Pismo PowerBook from 2000-2008, because it was the only thing that could reliably suspend/resume. Switched to ThinkPads because Linux suspend/resume on x86 had gotten pretty reliable by then.

Right, thanks for correcting my faulty memory on the timing. It is possible that IBM tried to squeeze Apple, but given that IBM's interest in Transitive was for enterprise server migration, I suspect it is more likely that Apple got ti

Similar to DEC's FX!32 in that regard. FX!32 allowed running x86 Windows NT apps on Alpha Windows NT.

> Anyone know how they implemented PPC-to-x86 translation? They licensed Transitive's retargettable binary translator, and renamed it Rosetta; very Apple. It was originally a startup, but had been bought by IBM by the time Apple was

Language agnostic in that COM lets you use the C++ object model in any language you want.

Typically you map a VLAN to a priority via PFC (Priority Flow Control). You can do it with vconfig on Linux. Switch OSes have their own CLI for this. Some switches can do PFC for untagged packets. They classify based on DSCP, and map that t

Signal server is explicitly untrusted in the Signal threat model, which is must be due to being based in a country (like any other country) with laws that can be used to compel actions on the server's owners. They publish legal orders

I don't use iOS, so I'm not familiar, but surely there is a way to download app packages from their store to verify them and generally exercise due diligence and do security research?

The builds are reproducible, so you can compile it yourself and check to see that you get identical binaries.

Also tons of cheap hydro-power. There used to be lots of Aluminum smelting up there, but that mostly moved out of country in the late 70's/early 80's.

I recall (>20 years ago) reading TAOCP, and laughing to myself about how obsolete the section on sorting using multiple tape drives. And here we are. There are newer editions (2004, 2014) of the McKusick et al book, s/4.4 BSD/F

As a counter to this low-effort, flip comment, I semi-regularly take the Amtrak Capitol Corridor from San Jose to Sacramento. It is about 3 hours. It takes about 2 hours to drive with no traffic, but if you need to travel on a weekday durin

Prius will regen slowly when you take your foot off the gas. Just like a Tesla. The difference is that Teslas regen aggressively, so you really notice the deceleration, whereas a Prius will not start major regen braking until you press on t

> I guess that the OS changes would need to be extensive I don't think that is true. In the simplest case, you could modify the #UD handler to notice when the fault is caused by an AVX512 instruction running on an E-core, and then s

I very much don't understand why Intel didn't disable AVX-512 on the P cores, unless and until the OS writes to a new MSR that means "I understand that the P cores can do AVX-512, while the E cores cannot", and then enab

We're about a mile from downtown, and while rents and house prices have gone up substantially like they have everywhere in the bay area, it is still one of the more affordable areas in Mountain View. But location aside, there is very l

My wife and I live in Mountain View, which is arguably the heart of the valley. I had to buy a trickle charger for our car's battery, so we wouldn't have to jump it around once a month whenever we went to drive somewhere.

The issue with these sorts of HashCash schemes is that legitimate users need to PoW their messages on a battery powered phone with a basic CPU and GPU. Spammers can use big, mains-powered GPUs, or better yet, botnets full of stolen CPU-time
