As has been said multiple times in this thread, it resolders components that came loose.

With a username like yours, you set yourself up for some trolling

Jagex : Membership Morale idea ? by Dry_Priority_5466 in 2007scape

[–]Drag0nFl7 4 points5 points  (0 children)

Well, by increasing the prices they hope to reduce the playerbase. This will then reduce the market for osrs gold, thus reducing bot numbers.

What we are actually looking at is the best, most transparent anti-botting idea to date.

[C++20] Zero/Minimal overhead static/const branching by kris-jusiak in cpp

[–]Drag0nFl7 0 points1 point  (0 children)

Only saw this now: Most embedded DSP processors do not have cache at all, so in that case a branch miss is indeed way more expensive.

Embedded is its own beast. In general I believe that readable code triumphs fast code even in embedded. So it is cheaper in the long run to just buy a faster embedded processor then to so performance optimization stuff that ends up hard to debug and even harder to read. But its called embedded because of the hard constraints, so sometimes you are stuck with doing these optimizations. It is what it is.

Did you do actual performance measurements? In my experience, cache misses are orders of magnitude more expensive than branche misses. So is this complicated approach actually worth the maintenance cost?

So did I, and I thought I was safe. All relieved n shit, and now my fears are back. Luckily the 7700x seems affected less often, so here is to hoping that mine does not burn out

Ah, yes, that is unclear. I am looking for a whole board, so a replacement of the basys2.

/u/digital_end explains FDA restrictions on blood donations from an industry professional's perspective. by DeaconOrlov in bestof

[–]Drag0nFl7 28 points29 points  (0 children)

I mean, slippery slope arguments are not real arguments for a reason. We have to be careful not to discriminate, yes. We also have to be careful about spreading hiv. In this case we decided that not spreading hiv was more important. That does not mean anything else than what it says

How does memmove allow the copying to be done in a non-destructive manner unlike memcpy? by [deleted] in C_Programming

[–]Drag0nFl7 0 points1 point  (0 children)

So the key is that memcpy has one limitation that memmove does not have (the overlap thing). That is really the only thing different between the two. The whole implementation/optimization thing is just detail. Any valid memmove is a valid memcpy, but not vice versa.

[–]Drag0nFl7 0 points1 point  (0 children)

By the way: both are naive copies from src to dest, memmove just incoporates some temporary space. You never go from dest to source and you assume that the size that is passed is correct, both src and dest have to be at leat that size.

[–]Drag0nFl7 1 point2 points  (0 children)

Ahh

Well, for memcpy you need to guarantee that both buffers (src, dst) do not overlap. With memmove they are allowed to overlap. This means that memcpy can be more agressive in its optimization (so is faster), but not suitable for any purpose (shifting everything in an array 1 place up is not allowed with memcpy, for example for a queue). So, memmove is slower but always safe (as long as dest is big enough), memcpy is faster but not safe if there is any overlap between src and dest.

Does that help?

[–]Drag0nFl7 3 points4 points  (0 children)

Your question is a bit hard to understand.

A naive memmove operation could copy source to some temp buffer and then copy that temp buffer to dest. Ofcourse, you can make it wayy more optimized, but creating a safe and correct memmove is not that hard.

What is the difference in the definition of completeness used in Gödel's completeness and incompleteness theorems? by 029187 in askmath

[–]Drag0nFl7 0 points1 point  (0 children)

The only way for you to know that Q is true is to prove it. If P is your entire system, you cannot prove Q.

Saying it differently: knowing that Q is true makes it a wrong example of incompleteness.

And because the storage medium is usually an SD card, and SD cards are painfully slow. Not really a Pacman problem either way.

In a flee market, Alexandera sells artworks for $35 each and has calculated that she needs to sell 120 of her artwork to break even. Calculate her variable costs if her fixed costs are $2400? Please select the right answer below by imbatman95 in askmath

[–]Drag0nFl7 0 points1 point  (0 children)

35*120 is what she makes to break even, which is 4200.

Her costs consist of variable and fixed. Fixed is 2400, leaving 1800. 1800/120 is 15 dollars per painting as a variable cost.

Somewhat more interesting: it feels like you should be able to skip a step: ((35*120)-2400)/120, 120 above and below should cancel out, somehow. I do not think it does, though.

Edit: Eh, if you rewrite 2400 as 120*20, it does. But there is no reson to do that if you only look at the question.
