Variable Passwords

 

A lot of people are guilty are of the one cardinal sin to do with passwords, that is using the same password for every single account. We all know that we shouldn’t but it’s just so hard to have all our passwords secure, unique and memorable. The idea of variable passwords is as long as you remember the steps to get the password all of your accounts can have unique and secure passwords.

The idea is you have a constant password which should be a secure password to start off with, for help choosing a secure password read my article on choosing a secure password. The constant password is used in all of your passwords. Added to the constant will be a variable that is different for every account/service, the way the variable is decided and added can be as easy or as hard as you want.

The variable has to be something to do with the website or service it will be used for, a good example would be the website URL. The first or last 3 letters of the URL could be the variable, once we have the variable could be put on the end of constant or in the middle. Here is a simple examples:

Constant = password

URL = gmail.com

Variable at the end : passwordgma

Variable in the middle : passgmaword

 

Although this would make your password more secure it maybe noticed that your gmail password has “gma” in it, a better idea would be to change variable in to numbers. The easiest way would be a=1, b=2, c =3 and so on. So “gma” now becomes: 7131 (g=7, m=13, a=1).Which is hard to see how the variable was decided. Taking that one step further you could alternate between the constant and variable password. This could be either the initial variable or the number variable derived from the initial variable. Here are some examples:

Varible Passwords

 

The idea can be expanded to reverse the variable before you use it or add your birth date on to the variable once it has been converted to numbers. The idea of variable passwords can be as simple or complex as you want it to be, As long as you can remember the steps to get your variable and how they are placed in the password you should never forget any of your unique and secure passwords again.

Uses for a Raspberry Pi

With the Raspberry Pi about to ship I’m sure everyone is trying to think of some uses for them, So here is a list of uses I could think of  for the Raspberry Pi

Low Cost NAS

Using the 2 USB ports it is possiable to setup a home nas, unfortunatly freenas dont do a ARM processor build. The buffalo terastation is an arm based NAS so it is possable to do.

Web Server

fedora are making sure that apache most used web server is working so it can be used on the Raspberry Pi’s ARM processor, i dont suggest it for a high traffic web site but it would be great for a person site or web development.

Digital Sign

The Raspberry Pi is a great little low cost and low power consumption PC to use to power a digital signage solution. It is more than capiable for displaying a web page.

Low Power Consumption Torrent Server

With the Raspberry Pi you would no longer have to leave your PC on to download your torrents, with a usb harddrive connect or maybe mapped back to a shared on your nas you can download torrents all day every

Mobile Wireless Access Point

The Raspberry Pi is powered by mini usb which makes it great to be used as a mobile Wireless Access Point, but currently im not sure if anyone has got a usb 3g modem working with the ARM processor yet.

Educational Use

I currently work in education and it would be a great low cost device to teach programming on, it has been said to be the BBC micro for the new generation.

If you have any more ideas for uses share them in the comments

iMessage Spam

If your looking to block iMessage spam check out this blog post : How to block iMessage spam

Will iMessage spam be the next big thing for mobile marking spammers? Just like Facetime that started out on IOS devices and soon made its way to OSX, iMessage will probably follow soon enough. But what would be the use of having iMessage on a device that wasn’t in your pocket? well there isn’t so apple may add iMessage to the rest if their products on me.com

 

If you search iMessage spam there are the first few reports from people about iMessage spam but at the moment it isn’t a problem the majority have. But there is a problem with the current iMessage system unlike Blackberry Messenger you do not have to add before they can message you, so any one with your iMessage phone number or email address is able to send you anything they wish. Some thing that most people won’t have noticed because you only give out your iMessage to people you want to contact you, but currently there isn’t a way to block people on iMessenger, the only way is to turn off your iMessage.

I’m sure that apple with be able to stop certain iMessage accounts if they get to many complaints but it is easy enough to open up another iTunes account and continue their spam campaign.
