No, the problem really is the prefetch itself when there are undesirable side-effects if the bus sees that memory read.
Speculative instruction fetches fetch code from "a location that you never asked it to execute code at" by design. If it already knew you asked it to execute code there, it wouldn't be speculative. The Armv8/9-A…
"Speculative instruction fetch to device memory crashes device" is in my list of favorite bugs ever found. I had ran into it on a Cortex-M4 without an MPU, so I couldn't even fix the memory attributes, the only solution…
I configure Mutt to run the HTML part through w3m and show me that instead of the text part, because of this exact misuse of multipart/alternative.
Most transport category aircraft have a better glide ratio than most single engine GA planes when configured for best glide. But they don’t cruise descend at best glide speeds or at idle thrust. I’m talking about turbo…
A car going down a slight hill on the freeway still needs a bit of gas to maintain speed. My assertion is that there are no turboprop plans that can maintain a 3° glideslope at normal approach speed without thrust from…
Not really much room. Unlike a car going down a hill, an airplane descending still wants thrust from the engines, just not as much as in cruise.
Don’t conflate airplanes with rockets. On an airplane, most of the energy in cruise is spent overcoming parasitic drag, not induced drag. It’s spent pushing the airmass out of the way as it moves forward, not creating…
strlen for netstring is O(log n).
It's mathematically impossible to describe an arbitrary length in a fixed length.
Because then the caller needs to treat it differently from non-empty buffers.
I live in the United States. I write software for a living. My wife is a physician. If I had a need to spend $2k, I could do so easily, but I still think it’s a lot of money to burn. I wouldn’t spend it on a whim; I…
This feels like too far the other direction. I am of the opinion that the following are all reasonable, and I think most people would agree with me: * Toll enforcement (the only thing allowed by the law) * Speeding…
I don't care too much about hot-rodders either. California specifically requires the original emissions equipment remain intact. Here's two cases where that fails: 1. Close to 20 years ago I read about someone who…
Periodic vehicle inspection for emissions and safety compliance. Many jurisdictions already have this for gas engine emissions, a handful of states already have safety inspections. Done right, it can be low burden and…
My experience is that there's a correlation between powerful type systems and the property that once your program compiles, it's correct. Compiles == correct is rarely true in C or JavaScript. It's often true in Haskell…
Assuming you mean in the United Stares, can you cite a specific law or court case to support your position? It occurs to me that the existence of paparazzi seems to be evidence against your position.
Or just `strace`.
This isn't the first time this month I've read about someone suffering consequences of mistaken identity after their facial recognition said they look like someone who committed a crime. I'm sure this is starting to…
If, like me, you were wondering how a 52 year old could have been a developer on a game you remember playing on an NES in the late 80s or early 90s: It looks like Īda's Castlevania involvement started around 2003,…
My insurance agent has recommended that once a year or so I carefully walk through the house with a video recorder, opening every cabinet and drawer and tool box and so on. It's easier than constructing a detailed…
This is what I do too, but be warned about “fire proof” - a fire that results in the total loss of your house will create enough heat for enough time that fireproof gun safes and smaller fireproof lockboxes will be…
As someone who recently replaced a few windows in my house, I can say in no uncertain terms that spending $1200 for a lamp and paying to feed it 0.58kW is cheaper than hiring a contractor to add another window. And it…
This is really useful for those of us who are really only familiar with the US system. Let me restate a few things to make sure I understand, and follow with some questions: 1. The "procureur" and "juge d'instruction"…
I'm reminded of the monologue from Terminator 2: > Watching John with the machine, it was suddenly so clear. The Terminator would never stop, it would never leave him... it would always be there. And it would never hurt…
