Project Zero Exploits 'Unexploitable' Glibc Bug

pjt33 Re:C Needs Bounds Checking (97 comments)

The compiler doesn't always know how big that free space is, because there's no type or size associated with it. It's possible in some cases to do bounds-checking, but not in many others. It's a fundamental difficulty with the language, and it's impossible for the compiler to check all those bounds without help from the language or the programmer.

That's not quite true: the compiler could arrange to pass around more than just the raw pointer (or in extremis could maintain a duplicate of the malloc table and work out the bounds given the pointer), but the performance hit would be considerably more than for direct checking.

13-Year-Old Finds Fungus Deadly To AIDS Patients Growing On Trees

pjt33 Re:English isn't my native language, but... (134 comments)

Only two? I think that grammatically any of the three nouns could be the one that's growing on trees. The 13-year-old growing on trees is even more semantically problematic than the AIDS patients.

The First Particle Physics Evidence of Physics Beyond the Standard Model?

pjt33 Re:Desensationalised (97 comments)

"This is /. after all" was intended to refer to "I admit not having read", but now that you point it out I suppose it is fair to say that most of the stuff posted is clickbait. I couldn't say in general whether that's because it's submitted by the authors of the links or because submitters can't be bothered to track back to the less sensational source.

The First Particle Physics Evidence of Physics Beyond the Standard Model?

pjt33 Desensationalised (97 comments)

I admit not having read the clickbait (this is /. after all), but I presume that the real story behind it is that an experiment to measure the muon magnetic moment has recently moved from Brookhaven to Fermilab to get access to more energetic muons. They're hoping to start measuring data in 2.5 years.

Leaked Documents: GCHQ Made Port-Scanning Entire Countries a Standard Spy Tool

pjt33 Re:And we're surprised why? (58 comments)

Well, if we use the same kind of accounting principles that were used to try to extradite Gary McKinnon, this is an article about an intelligence agency causing potentially billions of pounds/dollars/euros of damage to computers, 99%+ of which were not "legitimate targets" for a black bag job. It may not be a surprise, but it's still rather embarrassing.

Switching Game Engines Halfway Through Development

pjt33 Re:Rise of the middlemen (127 comments)

$42k would be low for an entry-level video game developer in a low cost of living area even as just a salary.

You're thinking in US terms. It's pretty good in the UK (25k GBP, which is the top end of what the main UK graduate careers site thinks an entry-level game programmer might get).

Researchers Make Fruit Flies Perform Aerobatics Like Spitfire Pilots

pjt33 Re:Good (51 comments)

There have been cases (at least two reported this year) of people burning down houses when using this approach, so a modicum of caution is indicated.

Ask Slashdot: "Real" Computer Scientists vs. Modern Curriculum?

pjt33 Re:Real computer scientists (637 comments)

Also, real computer scientists know who the fucking founding father of the discipline is.

I used to think I was a computer scientist, but now I'm not sure. Euclid? Diophantus? Babbage? Lovelace (albeit she'd be a founding mother)? Church? Goedel?

The UK one which inspired the US one is actually mentioned in the summary, but if you're assuming that 90% of /.ers won't even RTFS you're probably right.

Judge Shoots Down "Bitcoin Isn't Money" Argument In Silk Road Trial

pjt33 Re:Moron Judge (135 comments)

But he's not charged with money laundering. He's charged with conspiracy to launder money. If dirty money comes in and clean money comes out then money laundering has occurred, whether or not some of the intermediate steps involved the exchange of non-monetary assets. So "I was only involved in transactions involving the exchange of non-monetary assets" is irrelevant: what matters is a) whether they were part of a larger chain of transactions to launder money; b) whether he was aware of that larger chain.

European Commission Spokesman: Google Removing Link Was "not a Good Judgement"

pjt33 Re:Well, duh... (210 comments)

"A new law that has a fairly vague scope"? It's a law which dates back to 1995, and its scope is fairly clear. See the ECJ's Factsheet.

European Commission Spokesman: Google Removing Link Was "not a Good Judgement"

pjt33 Re:My two cents... (210 comments)

Google shouldn't have to make intelligent decisions as to what needs to be removed.

Why not? Every other company which does business in the EU has to make intelligent decisions about how it implements the law, including those aspects which allow for a data subject to request deletion of personal data which was collected, stored, and processed without consent or legal necessity.

Federal Judge Rules US No-fly List Violates Constitution

pjt33 Non-citizens are still humans (276 comments)

We are talking about US citizens, right?

What on Earth does that have to do with it? It's perfectly reasonable for the law to distinguish between citizens and non-citizens in matters like residence. I'll even grant that it's not unreasonable for it to distinguish between citizens and non-citizens in the question of who can vote - although that flies in the face of the professed reason for the US War of Independence; and as someone who lives and pays taxes in a country where I'm not a citizen it sometimes irritates me that I can't be fully involved in politics. But in basic matters of human rights like the right to the presumption of innocence, which is what this is about, nationality should be completely irrelevant.

Federal Judge Rules US No-fly List Violates Constitution

pjt33 Re:Awesome! (276 comments)

The courts decide what the law means, as well. That sometimes ends up in effect changing it, although from a strict legal point of view it isn't.

Ocean currents proposed as cause of magnetic field

pjt33 pjt33 writes  |  more than 5 years ago

pjt33 (739471) writes "The Institute of Physics reports a recently published paper which proposes that ocean currents could account for Earth's magnetic field. The currently predominant theory is that the cause is molten iron flowing in the Earth's outer core. There is at present no direct evidence for either theory."
