Fixing the PS3 Yellow Light of Death

My sister’s fiancé, Justin, had a 40gb Playstation 3, that unfortunately started experiencing the yellow light of death – which is similar to the XBox 360′s red ring of death. Some people say this problem is not fixable; others recommend heating up the back of the system with a hairdryer for approximately 15 minutes as a temporary fix. Justin told me if I could fix the PS3 it would be mine to do with it as I please and if I couldn’t fix it, then I could use it for parts. I had a PS3, but it was a broken one… fortunately, I found a series of videos by YouTube user gilksy1 that demonstrated how to repair the PS3 step-by-step.

Using these videos, I was able to repair the PS3 and go from yellow light to green light. I had to disassemble the PS3 and get to the CPU and GPU, which was a timely task. There were many screws to unscrew and lots of parts to remove. Once I finally got down to the CPU and GPU, I cleaned off the old heat sink paste and replaced it with new Arctic Silver 5 thermal compound. Also, using a heat gun I heated some of the soldering points up to about 680 degrees Fahrenheit. After letting the parts cool, it was time to reassemble the PS3.

Computer Security Programs I Use

One question I’m asked frequently by people wanting to beef up their computer security is “What programs do you use to keep your computer virus free?” While I don’t use too many programs, most of these people are looking for one program to take care of all their problems. Once I mention the second program, their eyes start to glaze over and they look as confused as a cow on AstroTurf. To help enlighten people who are looking to beef up their computer security, I am providing this list of software that I find helps keep my computer running in tip-top shape, while keeping my files secure. I have attempted to provide a brief description of each program to assist the user grasp an understanding of what the program does. If you don’t need the type of program, don’t use it.

avastavast! – This is a free antivirus program that does as good a job as any. You do not need to pay for Norton AntiVirus or McAfee. Avast will keep you safe and I find that it does a great job protecting against internet threats. Another terrific and free antivirus program is AVG. Microsoft has their own antivirus software named Microsoft Security Essentials and this is free as well. You should not be paying for virus and malware protection. These programs work well and are completely free.

Clonezilla – This is more of a backup utility, but it helps me get backup and running in case something happens to my computer. Clonezilla makes an image of your hard drive or partition and compresses the image to save on storage space. I make two images of each machine. The first image is after the install of the operating system, this allows me to have a clean operating system in minutes, rather than hours. Clonezilla can quickly restore the image it created and have you back up and running in no time at all. The next image I make is after I have all my essential programs installed. If I do happen to get a virus or think I have become a victim of malware I can revert to this image in minutes, saving me the frustration of having to run virus scans and hope all the malicious files have been removed. An alternative to Clonezilla is Norton Ghost, but it isn’t free, nor do I find it as useful.

I’ve been busy!

My last posts were back in early April, but I hope to resume posting again shortly. Last semester finished with a bang, everything coming due all at once. Once the semester ended I continued working, but also started at an internship in computer forensics. Of course I decided to go out guns blazing, so I’m enrolled in three summer courses as well. Then I will only have two classes left to take to finish my Masters in Digital Forensics.

I have some topics I plan on writing about, including password strength, programs I’m using, plugins I’m running for Firefox, etc. so stay tuned!

Fixing Blank WordPress Permalinks Admin Page

After installing WordPress and setting up this website I tried to set the site up exactly how I wanted it, by going through each page in the admin panel and playing with all the settings and learning what they did. By default, my install for permalink settings was set to “Default” which creates the URL at http://yourdomain.com/?p=123. This is not how I wanted my pages linked because it is poor SEO (Search Engine Optimization) practice.

I wanted the URL to display using the month and name setting (http://yourdomain.com/index.php/2011/04/sample-post/), but my Permalinks page was blank. I didn’t know how to change this outside of the admin interface, so I needed this page to work. Well, as you may notice from the URL of this page, I was able to fix the problem.

Fixing this issue is simple enough, here’s a quick how-to. First we need to download the misc.php file with FTP from the /wp-admin/includes/ directory. Open this file in your favorite PHP editor, I’m using Notepad++, if you don’t know how to edit a PHP file (and are running Windows), right-click on the misc.php file and choose edit with Notepad. Now with the file open we need to edit a line of code. For me, it was line 17.

Tracking Twitter Users with Creepy

Ioannis Kakavas, who prefers to go by Yiannis, is a Greek graduate student working towards a Master’s in Information and Communication Systems Security at Stockholm University and Royal Institute of Technology ( KTH ). On February 3, 2011 he introduced Creepy, which is exactly that. It is a geolocation information aggregator that collects Twitter, Flickr, and foursquare posts from any user you desire. It then parses the information shared publicly by the user and extracts the location.

To be clear, users are already sharing this information publicly – whether they know it or not is another matter. The geotagging is often provided to these networking sites through mobile devices (i.e. your phone). Creepy collects all of this information about the user searched and organizes it for the person viewing the tags in a nice, easy to understand map, as well as, listing all the post’s locations in the side.

Yiannis, says that this project has two goals. The first is to increase awareness about this capability and how easy it makes it for people to stalk you. Secondly, it’s a tool to add to a good guy’s toolbox. Obviously, the bad guys will be able to use it just as well.
