I need to get last four bytes out of a double variable .The platform is Arm and compiler is RVCT.Programming language used is C.What is the safest way.
Thanks
I've always followed the logic: if assert fails, then there is a bug. Root cause could either be:
Assert itself is invalid (bug)
There is a programming error (bug)
(no other options)
I.E. Are there any other conclusions one could come to? Are there cases where an assert would fail and there is no bug?
This question may not directly relate to programming. I have noticed that the technology of today has gone mobile. I want to go mobile with it. What is the most popular mobile OS?(excluding iPhone OS. Sorry, I don't have a Mac to develop on) Some choices could be BlackBerry OS, Windows Phone, Symbian OS, Android OS, etc. I want to make and sell applications for a mobile OS.
Programming challenge: Given a set of integers [1, 2, 3, 4, 5] I would like to generate all possible k-combinations in ascending size order in Java; e.g.
[1], [2], [3], [4], [5], [1, 2], [1, 3] ... [1, 2, 3, 4, 5]
It is fairly easy to produce a recursive solution that generates all combinations and then sort them afterwards but I imagine there's a more efficient way that removes the need for the additional sort.
A book beginning linux programming 3ed says "Note that fread and fwrite are not recommended for use with structured data.Part of the problem is that files written with fwrite are potentially nonportable between different machines." What does that mean exactly? what calls should I use if I want to write a portable structured data reader or writer? direct system calls?
I realise you can just #define some integers, but why didn't C have a dedicated boolean data type before C99?
It's such a common occurence in programming and logic, I don't understand the absense of an explicit type and notation.
Hell every body , i am newbie in linux programming ( Not Windows ) .

Alright, so I'm working on programming my own installer in C#, and what I'd like to do is something along the lines of put the files in the .exe, so I can do
File.Copy(file, filedir);
Or, if this isn't possible, is there another way of doing what I am attempting to do?
Thank you in advance.

Hello,
I have a very basic knowledge of the web programming, and I couldn't figure out the answer to this question.
Typically, a cookie is used to identify a session in web applications. However, as far as I know, multiple browser windows share cookies. In that case, how does web applications distinguish between the tabs?
I am trying to write a program containing two source files: main program written in C and assembly(x86 32 and 64) module callable from C. The C declaration for the assembly routine looks like this:
void mirrorbmp1(void *img, int width, int height)
The task involves Mirror/flipping a 1 bpp .BMP image horizontally while Handling any image width properly, not only multiples of 8.
I am new to assembly programming and have very little idea about how i should do the ask.
Any help would be appreciated.
I am looking for a solution to create a "virtual" webcam device under OS X (that acts just as a normal hardware webcam, but the application has full control over what to output). I'm fairly experienced with C++, but not so much with Objective-C and OSX/Cocoa programming.
Anyone that can point me in the right direction, where to look and what I should be looking for? I've searched, but most of the results seems to focus on Windows and DirectX.
Thanks!
basically i have read some samples, but all are self contained in one servlet.
such as: use doGet to establish the long polling connection, and then use doPost to trigger the event to notify all suspended connections.
Here is my question: I have other web actions programming in spring mvc, in the spring mvc controller a user post a message via /message/post, how can I make this action to trigger the atmosphere handler to notify the suspended connections?
I'm programming a function for a TI-NSpire, so I can't use the builtins from inside a function. What is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)
hello.
I would like to read about history of computing, is there some particular book you recommend about:
programming languages and their evolution
history of supercomputing and supercomputers
Thank you
I have done some computer graphical programming recently, and I have no experience before. I used the library call CGAL(computer geometry algorithm library). Also, I noticed that there is class for triangulation and also class for mesh. Is mesh just a kind of triangle net? Do they have any differences?
Thanks!
Hey, it's me again,
I've got another question regarding to basic Android programming:
How can I access the GPS for getting the current Position of the mobile phone the app is running on? How long can this take to retrieve the information?
In this case the GPS might be disabled, how can I enable/disable it again.
Which permissions must be granted in the andorid manifest?

Hello.
Qt library includes advanced meta-programming capabilities using they own preprocessing moc compiler. Does anyone knows, is it possible to create some kind of mix-ins via it? For example, i have a QString and want to add a method to it without sub-classing and changing existing code. Does Qt have such solutions for that?
What would be the most performant way to prepend a single character to a multi-gigabyte file (in my practical case, a 40GB file).
There is no limitation on the implementation to do this. Meaning it can be through a tool, a shell script, a program in any programming language, ...
Hi .. somewhat of a noob here to web programming. Just getting my feet wet in python. I wanted to implement web hooks in python. Both at server end and client end. Is there any particular library for implementing web hooks? Or does django or twisted python handle this?
Hi,
I'm looking for a python library for finding the longest common substring from a set of python strings.
I'have read that it exist to way to solve this problem :
- one using suffix trees
- the other using dynamic programming.
The method implemented is not important. Otherwise, it is important to have a implementation that can be use for a set of strings and not only two strings
Thanks,
