Learning assembly [closed]
...other (x86 computers included). But the likelihood that you are using ARM now and dont know enough assembler for it to write startup code or other routines knowing ARM may or may not help what you are trying to do. The second and more important reason for ARM first is because the instruction lengt...
What is Mocking?
...ecurity. The machine does this by processing what it sees with its camera.
Now your manager walks in the door and asks you to unit-test it.
Then you as a developer you can either bring 1000 real objects, like a MacBook pro, Google Nexus, a banana, an iPad etc in front of it and test and see if it al...
Why doesn't C++ have a garbage collector?
...age collection first of all. My main reason for asking this is that I do know that Bjarne Stroustrup has said that C++ will have a garbage collector at some point in time.

Convert string to number and add one

What does `someObject.new` do in Java?
...
@emory I'm not saying that, I know there can be perfectly valid reasons to want to make an inner class public, and return instances of the inner class from methods of the outer, but I would tend to design my code such that "outsiders" don't need to constru...
What are differences between AssemblyVersion, AssemblyFileVersion and AssemblyInformationalVersion?
...had back-tracked on this intent, and it is perhaps too late to change this now. I tried to search around the web to find out what happened with these plans, but I couldn’t find any answers. I still wanted to get to the bottom of it.
So I emailed Jeff Richter and asked him directly — I figured i...
What are the differences between poll and select?
...is library function both have this limit. But I
see that BSD/OS 2.1 has now been coded to avoid this limit, so it's
doable, just a small matter of programming. :-) Someone should file a
Solaris bug report on this, and see if it ever gets fixed.
With poll(), however, the user must alloc...
How do cache lines work?
...eval process can take ~90 nanoseconds, or ~250 clock cycles (from the CPU knowing the address to the CPU receiving data).
By contrast, a hit in L1 cache has a load-use latency of 3 or 4 cycles, and a store-reload has a store-forwarding latency of 4 or 5 cycles on modern x86 CPUs. Things are simila...
How do you detect where two line segments intersect? [closed]
...bering that s × r = − r × s):
u = (q − p) × r / (r × s)
Now there are four cases:
If r × s = 0 and (q − p) × r = 0, then the two lines are collinear.
In this case, express the endpoints of the second segment (q and q + s) in terms of the equation of the first li...
What's “P=NP?”, and why is it such a famous question? [closed]
...ix multiplication, the basic operation is multiplication of two numbers.
Now the question is, what does deterministic vs. non-deterministic mean? There is an abstract computational model, an imaginary computer called a Turing machine (TM). This machine has a finite number of states, and an infin...
