Android Studio - Waiting for device @ Ubuntu 

I have started to develop to Android on Ubuntu.
At my first attempt when I have tried run my app on the device, the device shown up as ?????????? in the Android Studio Choose Device dialog.

The problem root cause is the access rights around the device descriptors.

The ADB daemon is started with the user's permissions, so I had created an udev rule to get access to the device:

mm@lapos:/opt/android-studio/bin$ cat /etc/udev/rules.d/51-android.rules
# Concorde tablet (18d1:0003)
ATTR{idVendor}=="18d1",ATTR{idProduct}=="0003" MODE="0666"

AVR libc _delay_ms() does not works after upgrading to Ubuntu Raring Ringtail 

After upgrading my system to kUbuntu 13.04 Raring Ringtail the delays in my avr-gcc compiled binaries had been gone.
After reading the #include <util/delay.h> documentation my eyes cached the __DELAY_BACKWARD_COMPATIBLE__ macro. After defining it the delays are working.

Workaround:

#define F_CPU 16000000UL
#define __DELAY_BACKWARD_COMPATIBLE__
#include <util/delay.h>
#include <avr/io.h>

int main(void
{
DDRB = 0xFF;
while (1) {
PORTB = ~PORTB;
_delay_ms(1000);
}
}

Nokia VS JSR-234 FlashControl 

My father have a Nokia 6303i Classic, and he missed one feature from it: to be able to use the camera flash as torchlight.

According to the Device speciications, it supports the JSR-234:
http://www.developer.nokia.com/Devices/ ... i_classic/

1 Contains: CameraControl, SnapshotControl, FlashControl, FocusControl and ZoomControl

i have ditched together a small Midelt, and tried to run it on the device, but I get Flash method not supported exception.

Okay, lets check the getSupportedMethod

And the device have only one supported Flash mode the FlashControl.OFF.

I have not been able to believe it, so I have tried the Nokia C3-01 and the X2-00 at at the NOKIA RDA

But both devices produced the same behaviour.
Come on, why the hell did they implemented this API if it simply useless...

Strip phpmyadmin export to databases 

Exporting all tables with phpMyAdmin is not a good idea since there are some system tables which cannot be written during the importing.
(information_schema, mysql, performance_schema, test). If you did it as I you can strip the dump to databases using it the following php script:


<?php

$databaseComment = "-- Adat";

$handle = @fopen("localhost.sql", "r";);
$outhandle = 0;
if ($handle) {
while (($buffer = fgets($handle)) !== false) {
if (substr($buffer, 0, 7) == $databaseComment) {
$first = strrpos($buffer, ':';) + 3;
$length = strlen($buffer) - 2 - $first;
$dbName = substr($buffer, $first, $length);
echo $dbName."<br>";
if ($outHandle !== 0) {
fclose($outHandle);
}
$outHandle = @fopen($dbName.".sql", "w";);
}
if ($outHandle !== 0) {
fputs($outHandle, $buffer);
}
}
if (!feof($handle)) {
echo "Error: unexpected fgets() fail\n";
}
fclose($handle);
}

?>


Modify the $databaseComment variable to your database separating comments of your language settings.
