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.

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...
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...
Is it possible to run JavaFX applications on iOS, Android or Windows Phone 8?
...ad news first:
RoboVM is dead
Oracle killed JavaFX on Embedded Devices
Now, some good news:
JavaFX still runs on Android, iOS and most of the Embedded devices
JavaFXPorts SDK for android, iOS and embedded devices can be downloaded from here
JavaFXPorts project is still thriving and it is easie...
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...
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...
Speed comparison with Project Euler: C vs Python vs Erlang vs Haskell
...ex + 1) (triangle + index + 1)
main = print $ nextTriangle 1 1
EDIT: So now that we've explored that, lets address the questions
Question 1: Do erlang, python and haskell lose speed due to using
arbitrary length integers or don't they as long as the values are less
than MAXINT?
In Haske...
What are the best practices for SQLite on Android?
...that will be it.
So, multiple threads? Use one helper. Period. If you KNOW only one thread will be writing, you MAY be able to use multiple connections, and your reads will be faster, but buyer beware. I haven't tested that much.
Here's a blog post with far more detail and an example app.
An...
eval command in Bash and its typical uses
...s put double quotes around variable and command substitutions, unless you know you need to leave them off. Without the double quotes, the shell performs field splitting (i.e. it splits value of the variable or the output from the command into separate words) and then treats each word as a wildcard p...
