All the discussion was about virtual memory. The initial thread in a process, on every operating system that is still relevant today, uses guard pages to grow its virtual memory allocation for the stack segment. Physical memory for the stac

Yes, in my opinion it's flimsy and feels cheap, not as bad as some cheap Asus laptops, but worse even than a Dell Latitude, and the Dell is way worse than a Macbook or a ThinkPad. This is too bad, because the screen is excellent. My un

No 16:10 (or preferably even taller, like 4:3) screen, no buy. I really wish there was an alternative for the 16:10 mac I am using now, but there isn't anymore (apart from old ThinkPads, which I have many of[1]). I tried some Microsoft

No, the stack only grows for the initial thread in a process. Subsequent threads don't have growable stacks. And this is true for virtually every operating system that matters, not just Linux. Note that Go stacks can also shrink.

Google photos is extremely buggy too, and doesn't work the way I want it to work. It's almost impossible to upload a large number of photos from a desktop machine. It inevitably dies during the upload, then I have to figure out wh

I don't use social media. I have a Google+ account to share photos (and nothing else) with my family, but the bugs make that harder and harder, so I'll have to abandon it. (Any suggestions?)

Back then ICMBs were accurate to several miles, necessitating large bombs. Today they are accurate to meters. Not only you could do with smaller bombs, but it's feasible to attack many more targets. The destruction potential of today&#

No, it isn't. I just downloaded the latest version of the Tor Browser, 7.5, and while it comes with NoScript installed, it's turned off by default: https://i.imgur.com/7pb7nvI.png

Correct, and that is an US-internal dispute between whoever is responsible (FCC seems to think it is) and that particular company. But this HN discussion is not about that at all. Most of the comments here about jurisdiction in space. FCC h

There are 29000 pieces of debris in LEO larger than a cubesat, and 670000 larger than one cubic centimeter but smaller than a cubesat[1]. While space junk is a problem, a couple of cubesats are not making any difference. Space is big, even

On the contrary, now with locked smartphones and tablets this is very easy to implement. Of course it would be trivially defeatable, but that is never the point. The vast majority of people would not know how to defeat it. The law is not co

Why would Apple do such a thing? Presumably there would be fines if they didn't comply. If everybody is doing it (which is just Google and Apple, really), nobody gains or loses and advantage, so why would they care?

Notice how an electron hole also has all those properties. That's because those properties are due to specific symmetries of various fields (in space), or symmetries of space itself. Those properties are not "in" the particle

See my parallel comment, ringdown is different for black hole remnants vs. something else, so in principle we can tell if it resulted in a black hole or not. However, for objects of suitable mass (a.i. small) the current detectors don'

This is not correct, the nature of gravitational waves emitted by the merging of two objects is different in its final stage, depending whether the objects form a black hole or not. Until a black hole is formed, the nature of the emission i

You keep repeating this misconception even though you have been repeatedly been corrected over and over again. What you don't seem to realize is that the choice of coordinates in GR is arbitrary and local. There are types of coordinat

There's a reason why most music today is still mixed on an analog console. Notice that mixing and recording engineers, even if they use Logic to record, the computer is somewhere on the side, it's not in their face. They don'
