Building QCA (Qt cryptographic architecture) library on Ubuntu 13.10 with Qt5 

I have tried to build the QCA library from the KDE git repository (git clone git:// with Qt5. (The Ubuntu 13.10 distribution ships only QCA built with Qt4 in the repositories).

The cmake failed with:

CMake Error in CMakeLists.txt:
Imported target "Qt5::Core" includes non-existent path


in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:

* The path was deleted, renamed, or moved to another location.

* An install or uninstall procedure did not complete successfully.

* The installation package was faulty and references files it does not

The solution was creating a symlink from the mkspecs:

sudo ln -s /usr/share/qt5/mkspecs/ /usr/lib/x86_64-linux-gnu/qt5/

I have ditched together a small form in PHP to generate the setter getter methods for private members:

Mplab C18 to Mplab XC8 porting notes 

Just some random notes:

warning: (335) unknown pragma "udata"

Remove idata and udata pragmas.

(975) invalid format specifier or type modifier

Change %S string printf format specifier to %s (lower case).

Results a malformed string

If the next character after the escaped character is between [a-fA-F] then use a double quote between them:

Vesta Kombi fűtőbetét 

Miután az összes hazai szóba jöhető webshopot végignyálaztam a Vesta kombi tűzhelyhez fűtőszálat vagy fűtőbetétet keresve itt találtam rá egy hasonlóra: ... 3-kw-220-v

Igaz a PN nem ugyanaz (33.94023.192 az eredeti pedig 33.94023.002), illetve nagyobb teljesítményű 100W-al.

A csomag DHL-el jött relatíve drágán.

Azóta gyártó cég honlapját is megtaláltam:

Geovision GV-800(S) under Linux 

One of my friends asked me to get working a Geovision GV-800(S) DVR card with zoneminder.
According to the google results several people succeed with this subject. For e.g.:
http://siripong-computer-tips.blogspot. ... linux.html

I have installed a n Ubuntu 12.04 server, and the necessary packages. This distribution shuiips with a relatively new kernel (3.5.0) which means that the necessary bttv modules were included fine. The device had shown up fine: I had 4 v4l2 devices with 4 channels per each (Composite0-4). I have added these channels as sources to the Zoneminder but I have not been able to get image from them. After several trials I have installed XFCE and XAWTV. I have not been able to get image with that tool too, and at the channel changes I got I/O errors and the software claimed about invalid framebuffer address on startup.

As final trying I have installed a Windows XP to the box, and installed the Geovision software. The device had shown up in the device manager fine, but there were a yellow exclamation points next to the devices with Device cannot started message. I have seen that card working in different computer.

As a last trial we have decided to try to upgrade the BIOS, and that solved the problem.
