How to use a cd-image in .BIN file format?
You've just downloaded a CD-image in a BIN file format of your favorite game/software. What should you do with it now? It seems that none of the programs can read it.
The way to burn it or extract it is to create a CUE file that most of the burning/virtual drive tools know how to use.
Create a text file that is named exactly like your BIN file only with a CUE extension. Insert the next 3 lines to the file:
FILE "BinFilename.bin" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
Save the file (remember it should have the CUE extension).
Now, any software that reads cd-iso-images, like Nero, Daemon Tools, Alcohol 120%, will be able to read the CUE file and burn/extract it.
Enjoy!
Centering a block without using HTML <center> tag
To align a block to the center of the containing block you can set both 'margin-left' and 'margin-right' properties of the block to 'auto'.
The width of the internal block should of course be smaller than the parent's.
Use google cache to browse dead links
You have probably already seen and used the 'cache' link on the google results list. It's useful to get information from pages that do not exist anymore.
But actually, you can often use google's cache to retrieve information from any broken link. Just enter the following string in the google search box:
cache:"broken link"
And hope that google still have the page in their cache.
Is the egg boiled or raw?
Have you ever found an egg in a refrigerator and had no idea if it's already boiled or not? Well, there is an easy way to find out! Try spinning the egg around. If the spin is fast - the egg is already boiled. If the spin is slow and holds only for a couple of spins - the egg is raw.
The reason for that is that the raw egg is liquid inside, and this liquid is interfering with the spin.
Disposable GMail addresses
GMail supports creating unlimited number of email addresses from a single account - if your gmail is "someone@gmail.com" then all the emails sent to "someone+something@gmail.com" will also go into your inbox.
The advantage is that you can filter the emails based on the "to" field. So the next time you register at some site just enter a disposable address, and if it turns out to be spam - just filter it out!
Creativity boost with image search
Image searching tools - such as Google Images or Flickr - are great tools for getting your creative process going. Just enter some related term in the search field to get the related images on the screen. Browsing through the images will bring up various associations to your mind, which may help you getting on the right track.
Peeling a tomato
An easy way to peel a tomato (which you need to do if you're preparing a tomato pasta souce, for example) is cutting a small 'x' on top of it, and putting it in a steaming water. After a minute or two the skin around the 'x' will start peeling off. Take the tomato out, and easily remove the rest of the skin.
replacing string within file (linux)
perl -i~ -pe 's/abc/def/g' filename
Will replace the string abc with def in the file itself, and generate a backup of the original file in filename~. This command reads text from the file filename and writes it back into the same file where every occurrence of the string abc is replaced by def. The original contents of filename are copied into the file filename~.
Check if a number is a multiple of 3
You can know whether a number is a multiple of 3 by adding all the digits of the number, and checking if the sum is a multiple of 3 (which should be much easier).
Take the number 1052 for example. The sum of digits is 8 (1+0+5+2), which is not a multiple of 3. Therefore, neither is 1052.
