jQuery/javascript negation

JQuery Negation

if(!$(stuff).length > 5){
// If element ISNT LARGER THAN 5 so in our case the number of elements must be 0 1 2 3 4 and 5
$(this).doSomething();
}
else {
// The number of elements is GRATER THAN 5 // do another thing
}

Basically this is a negation of the following, god damnit my head hurts

if($(stuff).length < 5){
$(this).doSomething();
}
else {
$(this).doAnotherThing();
}

Oh well new day, new learned things. God Bless Amerika

JQuery IE Document/Window Errors

Dinulescu Alexandru Adrian — Mon, 28 Dec 2009 16:28:19 +0000

Hello

After working on the google shortcuts for a while, i decided to open up IE 8 and see if the application works or not. I was surprised and started to do the old alert("hax") thing every dozen lines. The problem is with the $(window).keypress(function(e){}). It seems that IE doesnt understand at all the $(window) property at all when it comes with keypress/keydown/keyup events.

After some research, this is a known issue from IE5 days, which is quite weird that jQuery didnt fix it in a way so it works with $(window)

However i did check the width/height properties and both values return different values.

jQuery

// instead of $(window).keypress(function(){});
// use
$(document).keypress(function(){});
// this is the testing
var windowH = $(window).height();
var windowW = $(window).width();
var documentH = $(document).height();
var documentW = $(document).width();
alert(windowH);
alert(documentH);
alert(windowW);
alert(documentW);

I did look over this issue over Google but I couldnt find any information about it. Really sad you know.

Windows 7 Taskbar

Evening All

MS messed up again, as always, Windows vista task bar is superior to windows 7 taskbar, both in look and feel (as well as polishing) and as functionality.

My Crucial issue with Windows 7 taskbar, was that in previous versions you could put only your taskbar on a side of the screen, like quick launch on the left side of the screen, and on the bottom the start menu / opened programs / right side icons ( the ones with the clock ). Well this is impossible to do with Windows 7, and i was so mad that i nearly uninstalled the software and switched to vista again HOWEVER, i found a program that can simulate this crucial missing feature called rocketdock which set with the windows vista black theme, left side alignment, 28px icons, no zoom when you touch an icon (mac dock sux), and always on top + autohide and some separators for good measurement (since the icons are too close together and you get something very similar.

SHAME ON YOU MICROSOFT!

WordPress DB possible issue -> Blog Takeover

Dinulescu Alexandru Adrian — Fri, 08 May 2009 18:04:49 +0000

Hello

Sometimes if your wordpress DB is down, you should normally get an error saying that the DB is unavailable and then some messages will appear with the possible cause of this, like the DB name is not found, the settings in the wp-config folder are wrong, and the like. However there is a case that surprise surprise you get on the page with the INSTALLATION of wordpress and you’ve just lost your WP blog.

The file is found in wp-admin/install.php

As a good rule of thumb, it’s advisable to delete all readme.txt, nfo, info files from all plug-ins, there have been reports of some chinese bots crawling wordpress blogs for these, so save yourself some bandwidth and delete those

In order to make sure this doesnt happen at all, there are 3 methods

Method 1: JUST NUKE the INSTALL.php file. After the blog has been installed you dont need this file anymore so just delete it
Method 2: htaccess file
# PROTECT install.php
<Files install.php>
Order Allow,Deny
Deny from all
Satisfy all
Files>
Method 3: Replace it entirely with something else that is written by you from the start

Problem Fixed
