I read already different postings about using databases on the Pi. Mainly sqlite3 is advised in most situations. What I want to achieve is that different sensors send data (of course this can happen simultaneously) to the Pi. I suppose since sqlite3 is a single user db probably its not suited for t...

Most likely your program just losing control - like stack overflow, buffer overflow, array index out of bounds etc

Can you show the example of non-working loop code?

Very good Python or Java programmer can create code that will be both smaller and faster, than C++ code written by average C++ developer. Proven many times.

Actually, assembler is one of the few languages that do not require any IDE to code effectively. And you can code, compile and run on the Pi itself.
Personally, I did assembly programming for 30+ years and never used any IDE.
So notepad or whatever you feel comfortable with - is your right choice.

Mentioning your target OS and frontend might help. Qt/SDL/Allegro/bare metal etc

Hi all, Is possible simplify this match? (nt.nti.nai.abtUid[0] == 0x0000000e && nt.nti.nai.abtUid[1] == 0x00000021 && nt.nti.nai.abtUid[2] == 0x000000d4 && nt.nti.nai.abtUid[3] == 0x000000c6) nt.nti.nai.abtUid have more than 4 numbers and I want simply comparator where anoth...

Is there a way to do fractal graphics using the pi and some linux version? Depends on what do you mean by "fractal graphics". I generated seamless tiled fractal background for my apps really fast with plain J2ME on low end mobile phone. IFS fractals or simple ones like Mandelbrot/Julia ca...

To draw fast you need to use the OpenGL ES , OpenVG or DispmanX 2D API to get the most performance out of the Raspberry Pi by taking advantage of its VideoCore IV GPU, rendering will then be fast using any JRE. These three API work without using X11. There exist many Java bindings and frameworks th...

Hi, I've found following display solution for Pi: http://www.ebay.com/itm/180974436891 7 inch 800x480 LCD comes with driver board, which allows to directly connect to HDMI output of your Pi. No additional software drivers required. Just edit /boot/config.txt as mentioned here: http://www.raspberrypi...

Don't listen to anyone. Start learning pure C (not C++). It will take about 4 hours to learn. All you need is in wikipedia. And next, you decide what to do with your future programming skills. If you want to be able to write 300K code per day and get a decent job with high salary - Java is for you. ...

Here is short tutorial for someone inexperienced like me. I'm not sure whether it is optimal, but it worked. This tutorial is for Linux host PC. 1. Prepare your Linux host. I created directory raspidev in my HOME mkdir raspidev cd raspidev mkdir SDL_cross 2. Get official cross tools for Raspberry Pi...

Now click on browse code and find the file extra/git_hash in this you will find a (complete) git commit ID for the raspberrypi/linux repository which you can use to check out the corresponding source code for your kernel from the raspberrypi/linux repository. I have no trouble with the steps previo...

I have designed a 7" HDMI LCD Display for the Raspberry Pi. After a lots of fixes I could make the display work for latest version of Raspbian and updated firmware ... more details of the display 7" 800 x 480 x3(RGB) TFT screen with TI's HDMI decoder and Microchip's USB Touch screen contr...

No lightweight java IDEs. Forget it. Raspberry Pi is beautiful platform to run java compiled classes, and believe me, performance is enough for very serious applications. But developing in java on Raspberry Pi is waste of time. No one does this. So get a PC with Windows/Mac/Linux, buy Intellij IDEA ...

Well, it is actually D. Braben who bans any elite sources (derived from original BBC sources) found on the net... Good thing he can't ban Ian Bell)))
