At one time or another we’ve probably all had problems with Windows. Lets face it, being the most popular consumer Operating System it’s the primary target for spy ware and viruses. Sure you can use the Windows CD to run some repairs, or the Ubuntu boot disc that I previously showed you how to make to back up your data but there is a much better option to use. The Ultimate Boot CD for Windows.
By now you should have a pretty good idea how powershell can be leveraged to help you with all sorts of tasks. This tutorial will cover the foreach loop to show you how you can chew through collections such as string arrays or windows services. There are two types of foreach loops in powershell, the foreach statement and the foreach-object cmdlet. They work similarly and you can get the same results with either, but they do differ in several important areas.
I couldn’t really pin-point one subject for my blog entry, so I’ll cover a few things that I found interesting!
Computer World is reporting that the new “I’m a PC” ad campaign for Microsoft was actually created on a Mac. Some of the source files are tagged with “Adobe Photoshop CS3 Macintosh” in the picture properties. Granted, not all of them were tagged like this, however; when trying to clean up the already poor reputation of Vista™ you could at least… you know, use the operating system you’re trying to save.
Asus, as reported by Ars Technica, had a bit of a blunder recently. It seems they released restore DVDs that also included a cracking tool for winRAR, confidential Microsoft documents for PC Manufacturers, and Asus source code. Asus will be tracking this issue down and dealing with it but expect to see lawsuits from RARlab.
And finally, for the conspiracy theory buff in us all left wondering how we’re still alive, the Large Hadron Collider has been taken offline until spring of 2009 due to a liquid helium leak. Rest easy knowing that you’ve got a few more months until we’re all sucked into oblivion! I am, of course, kidding… but there’s a 1:1,000,000,000 chance* that I’m not.
*figures not accurate.
Ever been doing something on the internet and seen one of those boxes with the crazy letters that you have to type in the letters before it’ll let you finish you’re post or comment on you’re friends Myspace page? It’s called a CAPTCHA which is an acronym for Completely Automated Public Turing Test to Tell Computers and Humans Apart. They’re also known as a type of Human Interaction Proof (HIP). You’ve probably seen CAPTCHA test on lots of Web sites and you have to type them in correctly in order to complete the form.
The reason behind CAPTCHA is quite simply to stop people from exploiting a weakness in the computers running the site. While these people make up a minority of all the people on the internet, their actions can affect millions of users. For example, a free email service might find itself over run with account requests from an automated program which could be part of a larger attempt to send out spam mail to millions of people. CAPTCHA tests help prevent this from happening.
When windows performs it’s updates, often but not always some of the hot fixes leave backup files so that you can later uninstall those hot fixes should they themselves be a problem. Normally these backup files present no issue and can simply be ignored. On the occasions where this is not the case and you need or simply want that space back, there is a free tool to help.
