I built a (research) library a few years ago to rewrite ELF binaries; our research projects ran into a lot of limitations with doing incremental patches to a binary (ELF has a lot …

I don't think the pilot factors in that much into the cost of operating a helicopter. Even a small helicopter (e.g. Robinson R-44 which is a bare bones trainer) needs a ~250k compl…

Well, we start running one instruction, it just never quite finishes. The other OISC systems run way more than one instruction, they’re just always the same one with different para…

Atomic clocks show up on surplus auctions/stores somewhat frequently (they’re called a Caesium frequency standard, e.g. the HP 5071). There’s a few reports of enthusiasts keeping t…

It’s not even desktop users; most desktop users download Ubuntu and never touch anything, on reasonably common PC hardware. Kernel regressions mostly get caught in the Ubuntu betas…

But do you want your box to send silently corrupted data for the next two years? Or would you rather reboot every night, and maybe escalate to your red hat support contract, where …

Fixing all memory corruption bugs is infeasible without fundamentally changing the way Linux is developed. There is so much code (and it’s being added to, changed, etc.) written by…

A few points: 1) failing loudly is better than failing silently. A memory corruption issue (or a bad refcount, etc.) is not a benign issue that only becomes relevant under carefull…

At least in the east bay, one reason why HOV lanes might run more effectively is that they are also express lanes (limited points at which you can merge in and out). On the other l…

Car companies (at least European ones) tend to be pretty transparent about this: - Audi (example): letter (car/SUV/race car)+ number (quality: 1-cheap, 8-luxury) - BMW: first numbe…

This simplified algorithm doesn't distinguish between learners (readers) and proposers (writers) to the value. I'd say this conveys the core ideas of paxos, and it makes sense to t…

Error-prone is somewhat tied to a specific version of the Java compiler -- so you need Javac 8, but you can set --source to an older version of the language. If the newer Javac doe…

A lot of research has been made in this direction by the PaX team/brad spender of grsecurity. In fact, many of these techniques were first implemented on modern kernels by that bun…

C++ compilers (at least on most current code bases that don't need modules) still need to parse and lex headers though -- so actual executable code is pretty rare. Most compilation…

One approach to reducing vehicle collisions that wasnt mentioned much in the discussion so far are road rules and design. It is unrealistic to expect perfect responses from human d…

This argument will seem a bit more empathetic if you don't consider it as killing 59 people outright, but increasing risk factors so that on average 59 additional deaths occurred(u…

Your mechanic doesn't do much work Porsches. I have used them a lot in the past when I had a Saab (which is ultimately gm/American technology), but now that I have a decade old Mer…

guidelines on what rules can do (e.g. That restrict rules on other actions) act to increase agency, not decrease it so I'd say they reduce the amount of bureaucratic hassle (they a…

Yes, but that exists in other places as well (usually zoning is done locally -- in Germany it's on the city or county level). However, the different categories and what zoning can …

In the other places in the US that I've visited or lived in, similar situations happened (e.g. University owned housing vs private student housing in the exact same building treate…

It always surprises me that a country that supposedly is one of the most "free-market" economies in the world and has a political rhethoric based on ridiculing overzealous regulati…

this style of evaluating people (what interesting things have you done) is quite problematic at that age, and forces students to do things for show from early one. I know there are…

Change your mechanic. The cheap (elm327) dongles can't write firmware onto ecus in any setup I am aware of -- elm327 is its own protocol and only supports the obd 2 standard operat…

Clever idea, however keep in mind that you are trusting both your file system permissions to be sane and your kernel to enforce them correctly (I.e. Not have bugs). a lot of projec…
