Well then what is the lower bound? The standard way to prove inequalities that should exist in a free market is through showing arbitrage patterns. This way one can prove f.eg. that a call option should never be more expensive than the unde

Java is the corporate powerhouse, especially for banking. Together with Oracle DB. Owning two out of three crucial components (the third being the hardware) creates a lot of good business opportunities for them, makes it easier to enforce m

Virtualization = huge power consumption and low performance. Not good for laptops, although quite reasonable for desktops.

China is just an example of a somehow comparable country that has risen pretty high. And regarding being a human: it is kind of hard when you have not eaten for three days, and your parents worry more about your baby brother that has just c

Unless you are talking about the embezzlement issue - i.e. employees pocketing single bills paid by the customers, which may get harder when you actually have to give back the change - your exercise has greatly outran my capabilities.

Often it just means they don't follow any teams, but not always. I, for instance, don't care for any sports at all. I'm not even interested in learning the rules, unless I play the sport myself. Same goes for some of my frien

The title of the article you provided is completely incorrect. There is no change to DNA detected by these studies. What gets changes is the expression level of individual genes. Expression level can be changed by almost everything, as it i

Yes, and it is worth noting that telomeres, while technically being DNA, do not code any proteins. In fact their complexity is at a completely trivial level - just a repeated sequence of "TTAGGG". This is also the part of DNA that

I'm still a student. But I do know this kind of knowledge is used in certain CS areas, such as computer graphics or algorithmic trading.

Thanks for the lwn and cambridge links, they both look like a good read. Considering the big picture I feel like we need another Tony Hoare to show us good ways to reason about shared memory concurrent programs. CSP is cool, but at some poi

I would really love to see the x86 multi-core architecture spec'd like this. To this day I don't really understand all the details behind x86 concurrency: memory, fences, atomics, concurrent operations ordering, mutex implementati

One of the first comments point out that this topic was already covered for example in the following 2011 paper: http://www.earth-syst-dynam.net/2/37/2011/esd-2-37-2011.html

Yes, that is absolutely correct. And I find it sad that such thoughtless mechanisms are exactly what powered the worst forms of racism in the history. Edit: would just like to point out that I was flagkilled before any response came, so cur

Stalin was loved by most of the Russians. There were more tears cried over his death than over Kim Jong-il's, and to this day many Russians keep Stalin's pictures in their homes. I believe that the West underestimates the strength

It is just ignorant to compare US police brutality to, say, Holodomor, and not see connections between Putin and Stalin.

It is just propaganda. And the negligence to admit that all citizens are subject to it, not only the non-democratic countries. I believe that such fear of "the others" (the communists in this case) is the root of any national iden

These tortures were only happening in Poland, just like the Holocaust was merely happening in Poland. I hope that this is what you mean by 'creatively' - i.e. just changing the place, not the people.

Can confirm this with respect to Polish aviation law. Flying a drone, or just any other aircraft - manned or unmanned - in a controlled space without prior authorization is a criminal offense. There is no question about it. Heathrow CTR&#x2

Well, that would be a lot of redundancy. Good isolation is hard to achieve (as proven by this post), why bother doing it twice? Is there any upside?

Regarding the .so configuration: can you show other examples? I find this technique fascinating, as it combines speed, expressiveness and actually ease of use. About the alternative heap implementation: can you point out who else has descri

I am not talking about mmap() vs write() here. That is just ordinary propaganda. There is a lot of powerful ideas at work there. The two that I know about: 1) Compiling config file into an .so object. 2) Using innovative priority queue (hea

This is not an easy way to serialize objects, it is merely a way to help virtual memory manager recognize portions of memory that can be saved to disk in the first place. .so files are loaded through mmap, and the pointers problem is solved

by xxxyy 12y ago
You just have to override the new operator (C++) or use a different malloc (C). All you need is to replace brk() with an appropriate mmap(). Don't know how it goes for Rust. C++ is especially appealing, because you can embed file-backe

I understand now. Not enough that the kernel unnecessarily loads a page that is about to be fully rewritten, it also blocks the thread that is trapped in a pagefault, while it could potentially go and serve another connection. I can see how
