C dynamically growing array
I have a program that reads a "raw" list of in-game entities, and I intend to make an array holding an index number (int) of an indeterminate number of entities, for processing various things. I would like to avoid using too much memory or CPU for keeping such indexes...
...
Expand a random range from 1–5 to 1–7
...e copies of each integer in the interval [1, 7], plus four zeroes. So the "raw" stream of results tends to an even mixture of [1, 7] values, plus some zeroes that occur a tad more frequently than any individual allowed value. But that doesn't matter because the zeros are stripped out, leaving just a...
Why does C++ not have reflection?
...object can be optimized away.
operator[] on a vector is only comparable to raw
array indexing in performance
because the entire operator can be
inlined and thus removed entirely
from the compiled code. C# and Java
make a lot of guarantees about the
output of the compiler. If I define
a class in C#, ...
Why is x86 ugly? Why is it considered inferior when compared to others? [closed]
...gly small as CPUs become more and more limited by memory bandwidth than by raw computation, but many "x86 bashing" articles and attitudes come from an era when this cost was comparatively much larger.
Update 2016: Anandtech has posted a discussion regarding opcode sizes under x64 and AArch64.

Two-way encryption: I need to store passwords that can be retrieved
...attack will also give them full access to the keys involved. Sniffing the raw HTTP traffic will also give them the keys.
Use SSL for all traffic. And make sure nothing on the server has any kind of vulnerabilities (CSRF, XSS, SQL Injection, Privilege Escalation, Remote Code Execution, etc).

How can I transform between the two styles of public key format, one “BEGIN RSA PUBLIC KEY”, the oth
...;setPublicKey();
echo $rsa->getPublicKey(CRYPT_RSA_PUBLIC_FORMAT_PKCS1_RAW);
The base64-encoded stuff appears to match even though the header says BEGIN PUBLIC KEY and not BEGIN RSA PUBLIC KEY. So maybe just use str_replace to fix that and you should be good to go!

Get path of executable
...ns a path with the ".." parts in it, like if it was taking the string pure raw from the command line lol. actually in this case visual studio is launching the process and the .. is part of the debugging path. something like $(projectDir)../some.exe I used PathCanonicalize from Shwlib but one needs ...
What kinds of patterns could I enforce on the code to make it easier to translate to another program
.....?
Profit!(?)
*by powerful I mean that this takes 4 lines:
myinput = raw_input("Enter something: ")
print myinput.replace('a', 'A')
print sum(ord(c) for c in myinput)
print myinput[::-1]
Show me another language that can do something like that in 4 lines, and I'll show you a language that's ...
What are the differences between Generics in C# and Java… and Templates in C++? [closed]
....dll or .class file, and the JVM/CLR will do stuff with this.
C++ produces raw x86 binary code. Everything is not an object, and there's no underlying virtual machine which needs to know about a Person class. There's no boxing or unboxing, and functions don't have to belong to classes, or indeed any...
Why do we need private subnet in VPC?
...where... but, in fairness, you're paying, in part, for some pretty serious raw packet switching power and network connectivity with the gateway.
