Want to achieve the box pictured above?

div.box {
   -webkit-box-shadow: 0 3px 3px rgba(0,0,0,0.20), rgba(0,0,0,0.12) 0px 0px 10px inset;
   -moz-box-shadow: 0 3px 3px rgba(0,0,0,0.20), rgba(0,0,0,0.12) 0px 0px 10px inset;
   -webkit-border-radius: 10px;
   -moz-border-radius: 10px;
   border: 1px solid #fff;
   padding: 6px;
   width: 200px;
   background: #fff;
}

In order to get it, we can simply check it out of a SVN repository. Execute this two commands:

sudo curl "http://www.chiark.greenend.org.uk/ucgi/~cjwatson/cvsweb/openssh/contrib/ssh-copy-id?rev=1.8;content-type=text%2Fplain" -o /usr/bin/ssh-copy-id
sudo chmod +x /usr/bin/ssh-copy-id

And you’re done!

1. Open the Console application
2. Go to File > Open and browse to your frontend_dev.log or desired log file in the symfony logs directory
3. Click Show Log List and select your newly opened file to avoid the clutter of the rest of the OS logs
4. You’re done! You can now take advantage of features like clearing the view, search, and more

To migrate ereg():

ereg('\.([^\.]*$)', $this->file_src_name, $extension);

becomes

preg_match('/\.([^\.]*$)/', $this->file_src_name, $extension);

Notice that I wrapped the pattern (\.([^\.]*$)) around / /, which are RegExp delimiters. If you find yourself escaping / too much (for an URL for example), you might want to use the # delimiter instead.

To migrate ereg_replace():

$this->file_dst_name_body = ereg_replace('[^A-Za-z0-9_]', '', $this->file_dst_name_body);

becomes

$this->file_dst_name_body = preg_replace('/[^A-Za-z0-9_]/', '', $this->file_dst_name_body);

Again, I just added delimiters to the pattern.
If you are using eregi functions (which are the case-insensitive version of ereg), you’ll notice there’re no equivalent pregi functions. This is because this functionality is handled by RegExp modifiers.

Basically, to make the pattern match characters in a case-insensitive way, append i after the delimiter:

eregi('\.([^\.]*$)', $this->file_src_name, $extension);

becomes

preg_match('/\.([^\.]*$)/i', $this->file_src_name, $extension);

Event.implement({

   hasCapsLock: function(){
      return ((this.code > 64 && this.code < 91 && !this.shift)
           || (this.code > 96 && this.code < 123 && this.shift));
   }

});

And then access the method from a keypress event:

$('test').addEvent('keypress', function(event){
   if (event.hasCapsLock()){
      // do something
   }
});

The only drawback is that it relies on sniffing alphabet characters and whether the shift key was pressed. This means that if the user presses the caps lock key, you won't know it until another character is inserted.

would produce a horrible result in IE, with noticeably lower quality in the resized version.

This is easily fixed in IE7 by applying the following property to the img tag:

img.thumb { -ms-interpolation-mode: bicubic; }

To create a unique file with the right permissions use the tempnam function:

$filename = tempnam('/tmp_directory', 'filePrefix');

You can test this from the command line like this:

php -R 'tempnam("/tmp", "hello");'

The output file looks something like this:

guillermo-rauchs-macbook-pro-15:tmp willy$ ls -la hello*
-rw-------  1 willy  staff  0 Mar 11 03:26 helloyvEzzb

Couple this function with sys_get_temp_dir and you’ve solved the dilemma:

$filename = tempnam(sys_get_temp_dir(), 'filePrefix');

One of them is -d, which alters a php.ini value for the duration of the command. An example is as follows:

php5 -d memory_limit=128M symfony propel:data-load

This was a real time saver considering the server was not setup with a CLI-specific php.ini, like some are.
