Re: My raspberry hangs too often to be usable

I did a quick search on the forum and find this amazing feature, thanks. I'll try as soon as possible, hoping that my HDMI cable supports CEC. It worked out of the box with my Sony TV and the current raspbmc image. No need to configure anything. I am using the HDMI cable offered by RS components fo...

If your TV supports CEC, you should be able to control XBMC via your TV remote control. Doesn't that work?

Re: Profiling on the Pi?

I use gperftools from the Arch repos and this works nicely: However, the current tarball did not compile on raspbian, because it used armv7 instructions even when compiling for armv6. Fortunately, a patch has been committed recently which solves this issue: http://code.google.com/p/gperftools/issue...

Re: Improving performance

Hi Sam, I tried to output the error using startx > error.txt but just got an empty file. Guess that doesn't work for everything? Or I did it wrong? I'd recommend reading the Wikipedia article on standard streams . Appending "> file" to a command will only redirect the standard output stream, but not...

Re: Improving performance

C sounds like a better way to do things then performance-wise, is that the reason it's more popular? I would not say that C is more popular than C++ or Java. It depends on the context. The history of the C programming language is strongly connected with the history of the UNIX operating system. Eve...

I still doubt that this will improve performance significantly. LXDE has a negligible footprint compared with any current web browser.

Re: Improving performance

Machine code = lowest programmable level of a CPU. 0's and 1's Although it is a common phrase, I do not find it helpful to define machine code as consisting of 0s and 1s, because source code and bytecode are represented as sequences of 0s and 1s, too. 0 and 1 are the (only) characters of the digita...

Re: Improving performance

what's the difference between bytecode and machine code? Machine code is 0s and 1s right? On the most primitive level, every digital device can only process 0s and 1s. Thus, bytecode is saved on your SD card as 0s and 1s as well. The difference is that machine code can be executed directly by the C...

Have you already tried a different SD card? My RPi is overclocked to 900 Mhz, and I am using a Samsung MB-SP8GA SD card. No issues with that card so far, and it has good performance for the price: 19.4 MB/s read throuput and 19.8 MB/s write throuput ...

Well the default terminal in Enlightenment 17 (Bodhi's WM) is called Terminology. Nothing happened when I rebooted though. Hm ... I am using Raspbian with manual X startup via "startx".

If you have installed a program named "terminology", this would be correct.

Yes in your home directory. "~" is just an alias for /home/<username>.

Re: Improving performance

With regards to X, I've never fully understood the distinction between X and GNOME/KDE/etc. I realise a DE/WM is built on top of X and a toolkit like GTK+ or Qt but I was under the impression X can be run without any GUI? Kind of like giving DOS the ability to fire up IE but I suppose without the w...

Keyboard only works on every third or fourth reboot

Hi all, One week ago, I bought this cheap wireless keyboard and mouse combo for my raspi. Back at home, I immediately tested the devices, as I already knew that some people are still facing issues with ignored or randomly repeated key presses. I was very glad to find out that both the keyboard and t...
