When compiling GLUT/GL graphics program vs a QT/GL program, a pointer into data (float **) must be decremented with the former and incremented for the latter. The data is hard-coded (float [3][6]) =...) and the pointer is initialized to the "top" of wherever, the same for both! Huh? -Martin Compac, AMD64, MS Vista, cygwin X-Server Get this and you win a cookie.

A new building is being constructed over the Chernobyl nuclear power plant. http://www.economist.com/news/science-and-technology/21633793-almost-three-decades-after-catastrophe-wrecked-it-proper-tomb?fsrc=scn%2Ffb%2Fte%2Fbl%2Fed%2FtheultimatesecurityblanketHowever they say that reactor 4 needs the nuclear waste removed and that no robots which can withstand the radiation and are dextrous enough currently exist. As I see it once the building is covered with the other building they should dismantle the lot. There doesn't need to be a smaller building. Chip away at it with diggers and remove all the structure around the reactor. That way the robots don't really need to b…

Hello! Well, there is a problem which I sort of don't know how to solve. Given a matrix starting at top left corner how do you find all possible paths given x steps. Example 3x3 matrix and you have 5 steps. 7 2 9 2 7 5 6 1 9 So now starting at 7 you need to find all possible paths/all possible sums using only 5 steps. You can move up, down, left right. Not diagonally or jump between numbers. You can't visit the numbers you already visited twice. I am working in C++. Regards!

i watched some articles and videos about Cooling severs with mineral oil,is it energy efficient than other methods especially for a small to medium size sever room (that use air conditioning system to cool the room )

How do I set up nameservers on windows 7??

Hello everyone. I have to create a school project where I have to: 1.create netwrok(LAN) 2.simulate and analyze network traffic 3.simulate network attacks They told me to use GNS3(https://community.gns3.com/welcome). In physical network I could for example install wireshark on 1 computer to analyze packets and use linux kali distribution to simulate network attacks. My question is how can I simulate network attacks for network created inside GNS3? (GNS3 is installed in virtual OS inside virtual box)

This question occurred to me some time ago when I was thinking about whether or not `if` statements are fundamental in computation. Consider a program that manages a single bank account (for the sake of simplicity). The bank account could be defined as something like Account { int balance; // current amount of Money boolean withdraw(int n) { if (balance >= n) { balance = balance -n; return true; } else return false; } void deposit(int n) { amount = amount + n; } } S…

Hi everyone I need to imply 2 "IF"-functions in one cell... Is this possible? Consider 3 cells: A1, B1 and C1. C1 should display "Yes" if A1 is larger than, or equal to one half of B1 AND it should display nothing if A1 is empty, but not zero (should A1 be zero, then C1 should be "No")! Is this possible? I tried on C1: =IF(A1 >= (1/2)*B1);Yes;No) AND IF(A1 = "";"";"") But this gives an error. Can someone give me a line? Thanks. F.

I am trying to build an algo to apply for jobs online. Does anyone have experience doing this? Thanks

So, a friend of mine is having a few troubles, and I recommended him maybe starting to get into app development and see if he can go from there. However, he has problems because of the limited technology he has to work with. Therefore, he has to rely on online alternatives because of the memory on his device. Is there an online android sdk environment that would allow him to program without dealing with extra software on his device?

Just in simple Terms... May be natural language.Could someone out there explain to me the meaning or intuition behind Polynomial time reduction. What exactly does it mean for a function to bounded by Polynomial time Thanks

New toy I found http://app.jbbres.com/actions/ has a neat zip/unzip files in a specified folder function.

The idea of the app is to allow users to relay their ideas in subjects ranging from Mathematics to Music Theory. Here is a screenshot of it so far. It is so far merely in its test phase, but I decided to release it because I wanted to get the community going. It may be a bit buggy at the moment. Currently, users can create nodes. I will soon be adding the ability to add onto nodes. I will also be adding discussion features. Note: Here is the download(Android only):https://www.dropbox.com/s/vf1rirsy37ic32o/Hyptric.apk?dl=0

Hello, i have a fan in my computer that needs to be started manually each time. I guess the fan is about to die. I use a wooden toothpick everytime going trough the "chassis grid" and pocking the fan untill it starts up. Sometime i look back at the toothpick and a very small part is missing. What if pieces of toothpick end up in my computer, what could possibly happen? (small pieces). the fan i manually try to start up with the toothpick is the one in the rear, close to the power supply.

Okay guys, I need some help. I know some C++, about enough to fit in one semester. When I took the course we covered a little bit passed arrays. Anyway, I never really understood how to make an actual application. We would write some code maybe about 300 lines at times, and we would run the code or some of you might call it "debug" and this is where the command prompt would pop up -- usually it would ask me to input some values to calculate whatever my code was intended to do. However, I never really learned how to make an application where you can actually interact with and do other things. What I mean by that is for example all the applications that you find in your mob…

If the cloud were truly universal could it be a prototype for a universal quantum computer ? Please advise.

When I am entering vaules to my float variables some of them are returning wrong huge numers. For example I entered 0 and it returned 916455424. Please can anybody tell me the reason or solution?

Hey guys (and girls), I am having a bit of difficulty researching how one goes about extracting data from a video file. I would be using high definition go pro's to capture the footage, and need to extract words from various surfaces. For example walking down the road with a go-pro and being able to gather the text from each sign that I pass and export that into a database. I am not looking for an simple answer to this question for I know it would be exhaustive. What I am looking for is maybe some direction on where to start looking. What terminology I type into Google to start my research? Are there any threads on here or other computer science / programmi…

Hey bit of a problem today guys . My old laptop fell off my desk earlier this morning and the LCD cracked, anything I can do to fix it?

My current project list is stacking up... I had an idea for a math app that people can use to share what they have found within a set of equations that is either completely new or has additions to it. This would create a new equation page, where people can add onto the equation. People also moderate the pages to ensure that the content is legitimate. What do you think? Has it already been made?
