  • US Trade Deficit Surges 11% in May Amid Export Decline | Sweden Herald

    Jump

  • This is the normal way to talk about changes in deficits and surpluses in English, and it’s not ambiguous, although it may look that way initially. In everyday speech, a “deficit” already means a shortfall or a negative amount. When we say a “surging deficit,” we mean the size of that shortfall is increasing. We generally treat deficits as only positive or zero (never negative), and if it flips, we call it a “surplus” instead.

  • electroweak unification

    Oh, that's easy! Just take your understanding of how spontaneous symmetry breaking works in QCD, apply it to the Higgs field instead, toss in the Higgs mechanism, and suddenly SU(2) × U(1) becomes electromagnetism plus weak force!

  • For those curious, I found this source: http://prefrontal.org/files/posters/Bennett-Salmon-2009.pdf (Bennet et al. 2009: Neural correlates of interspecies perspective taking in the post-mortem Atlantic Salmon: An argument for multiple comparisons correction)

    Essentially it's using a dead salmon as a lone control to argue that fMRI studies should be more rigorous in how they control for random noise.

  • Ubuntu To Revert "-O3" Optimizations, Continues Quest For Easier ARM64 Installations

  • I'd really rather we skip over ARM and head straight for RISC V. ARM is a step in the right direction though.

  • Fun fact, Rust has a special error message for this:

    Unicode character ';' (Greek Question Mark) looks like a semicolon, but it is not.

    It also detects other potentially confusing Unicode characters, like the division slash which looks like /.

  • I have this great idea for an app, we can go 70/30 on it! 70 for me because the idea is the hardest part after all. So basically it's Twitter plus Facebook plus Tinder with a built in MMO. You can get that done in a couple weeks, should be pretty easy right?

  • Texas Needs Equivalent of 30 Reactors to Meet Data Center Power Demand

    Jump

  • Texan here. I don't have a generator. Blackouts basically haven't been a thing in my area since like 15 years ago, so it really depends on location. Also my electric bill works the same way as it would in any other state; the problem is when people buy electricity at what you might call "market price": most of the time it's cheaper, but you get fucked over sooner or later. It's kind of like that story about people's AC being controlled by the power company. They signed up for a program that explicitly set your AC higher during high-demand periods and then surprise Pikachu faced when the company did what they said they would do.

    That said, our grid is still definitely trash (as are many other things here) and I'm desperately trying to move. Basically the only thing we've got going for us is the food is amazing.

  • Mozilla drops new Privacy Note and Terms of Service; People are saying it is Bad News

    Jump

  • In simple terms, they just don't allow you to write code that would be unsafe in those ways. There are different ways of doing that, but it's difficult to explain to a layperson. For one example, though, we can talk about "out of bounds access".

    Suppose you have a list of 10 numbers. In a memory unsafe language, you'd be able to tell the computer "set the 1 millionth number to be '50'". Simply put, this means you could modify data you're not supposed to be able to. In a safe language, the language might automatically check to make sure you're not trying to access something beyond the end of the list.

    Jump

  • No, the industry consensus is actually that open source tends to be more secure. The reason C++ is a problem is that it's possible, and very easy, to write code that has exploitable bugs. The largest and most relevant type of bug it enables is what's known as a memory safety bug. Elsewhere in this thread I linked this:

    https://www.chromium.org/Home/chromium-security/memory-safety/

    Which says 70% of exploits in chrome were due to memory safety issues. That page also links to this article, if you want to learn more about what "memory safety" means from a layperson's perspective:

  • Depends on a lot of factors. Due to uncontrollable factors like small untrackable debris, more satellites is always more dangerous, but that's still an extremely small problem. If all the Starlink-style companies cooperate properly and adopt high tech solutions for collision avoidance, it'll probably be fine - space is really, really big. Additionally, the extremely low orbits are a great mitigating factor for potential parts failures; even if a satellite outright dies, losing its telemetry and maneuvering capability, it'll be gone pretty quick.

    Honestly, more than anything, I'd be concerned about the recent science showing that satellites burning up on reentry could be very significantly more damaging to our atmosphere and the ozone layer than previously thought.

  • Yeah, it was ok when the project started. The issue begins once it transitions from a toy to a potential competitor with Firefox.

    Jump

  • Yeah, I know the history. And if they fully switch to Swift and manage decent performance, that would be acceptable, just strange. And it would also be fine to use whatever language if it were only a hobby project. I just reject the notion that C++ is an acceptable choice for new projects in security-critical positions.
