how to remove file from git without deleting it on drive
git reset HEAD CONTRIBUTING.md
symfony, permissions for apache and cli
run those commands to setup permissions for both apache2 and cli commands,
so you can run cache:clear command or remove app/cache/dev or app/cache/prod directories without subsequent problems with permission denied errors
HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1` sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
bash, run commands relative to .sh file
#!/bin/sh my_dir="$(dirname "$0")" cd $my_dir;
PhpStorm symfony – search only: src, web, app directories
In PhpStorm: open settings, find Scopes, add new scope, set name for scope
as pattern set:
file:*||file:src*/||file:app*/||file:web*/
after that, when searching “Find in path”, set “Scope” radio button to Custom and in select options find previously created name.
default composer path on windows
composer path used in windows environmental variables is:
C:\ProgramData\ComposerSetup\bin
This is default path of composer on windows machine when using windows installer.
Useful to set up PhpStorm command line tool support for composer, you need only paste this to configuration:
C:\ProgramData\ComposerSetup\bin\composer.phar

Zenbox.pl – cron setup
I don’t find that information using google so I think I should post it here.
If u want execute php script via php command in zenbox.pl cron u should add following command:
/usr/local/bin/php /home/lpodolski/domains/lpodolski.com/cron/refreshPage.php >/dev/null 2>&1
In zenbox controll panel this should look like this:
Of course for experienced users this is obvious, but zenbox.pl hosting platform main target are casual users who want to simply host their blog or email. So at first I have expected that standard command would work out of the box
php /home/lpodolski/domains/lpodolski.com/cron/refreshPage.php >/dev/null 2>&1
there is also no feedback that command was not successful, so it take me some time before i realize that this doesnt work
of course u can probably use standard wget url to open URL via CRON but in this case u allow cron executions for everyone:
wget -qO- http://lpodolski.com &> /dev/null
Polish spell checking for PhpStorm
In order to have Polish language spell checking In PhpStorm you must generate .dic file with words.
You can do that using linux command:
aspell --lang pl dump master | aspell --lang pl expand | tr ' ' '\n' > polish.dic
You can also download this file generated by me, by clicking: Polish PhpStorm dictionary
Next you go to settings, for single project or you can also set it as default (default setting wouldn’t apply to old procjects). Type in search “Spelling” change tab to “Dictionaries”, click + button to add folder where generated dictionary is placed. Apply. If not working, try to reboot PhpStorm.
Search key value pair in multidimensional array
How to search key value pair in multidimensional array? In other words search for subset of multidimensional, multilevel array by key and value pair.
This is solution to this problem, notice that in $arr[1] there is multidimensional array, and is also returned in output of search.
<?php
$arr = array(
0 => array(
'id' => 0,
'name' => "cat 1"
),
1 => array(
array(
'id' => 1,
'name' => "cat 1"
)
)
,
2 => array(
'id' => 2,
'name' => "cat 2"
)
);
$arrIterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($arr));
foreach ($arrIterator as $arrIteratorItem) {
$subArray = $arrIterator->getSubIterator();
if (isset($subArray['name']) && $subArray['name'] === 'cat 1') {
$outputArray[] = iterator_to_array($subArray);
}
}
print_r($outputArray);output of print_r :
Array
(
[0] => Array
(
[id] => 0
[name] => cat 1
)
[1] => Array
(
[id] => 1
[name] => cat 1
)
)BTW as you can see in first code snippet, it do not include closing ?> tag. As you can know closing PHP tag is optional. And if do not necessary you can and should not include it. This is because after closing PHP tag there could be empty white space character that will make problems with sessions. Ie. “headers already send” type of errors.

IIFE, more examples
I want expand my last post (Immediately invoked function expression aka IIFE), by more examples of using IIFE.
IIFE can be also used like this:
var foo = function() {
// code
}();However, it’s better practice to do this like this, because of code readability:
var foo = (function() {
// long code
})();If you have on your page jQuery and maybe other JS library that uses $ sing to access it. You may use this little pattern to pass library to IIFE, the way it will not make conflicts. And also get advantage of $ access to that library:
(function($) {
// code using $
})(jQuery);Also it helps with rendering animations:
(function animation_loop() {
window.requestAnimationFrame(animation_loop)
render():
})();It’s protect against unwanted globals:
(function() {
window.public = 'foo';
var private = 'bar';
})();
// latter on
public; // foo
private; // undefinedUseful if you want compute and return value in one statement:
var browser = {
vendor_prefix : (function() {
var prefix;
// compute stuff
return prefix;
})()
};Create a class in one statement:
var MyClass = (function() {
function MyClass(foo) {
this.foo = foo;
}
MyClass.prototype = {
bar : 'baz'
};
return MyClass;
})();Creating private variables:
var number = (function() {
var num =0,
add = function(n) { num = num + n;},
get = function() { return num; };
return { add:add, get:get};
})();create private functions:
var foo = (function() {
var priv = function() { alert('Hi'); },
publ = function() { priv(); }
return publ;
})();Sources:
Monitoring RAID status on Adaptec 5405 controller
#!/bin/bash DETECTOR=`/bin/arcconf getconfig 1 |grep -i optimal |wc -l` if [ "$DETECTOR" -ne "2" ] then echo "`/bin/arcconf getconfig 1`" | mail -s "There is problem with RAID" [email protected] fi
Of course, you must add it to cron, for example like this:
*/10 * * * * /usr/local/bin/raid_check.sh
This is what: arcconf getconfig 1 command returns:
Bellow command, show information about RAID configuration and status, and also about logical and physical devices.
