Welcome to the new yifan.lu!

It’s a new year, and I’m a bit tired of the old design. There were some main problems with it besides the looks though. The biggest one is I never wrote a backend for my “projects” list, so every time I add a new project, I’m doing it manually by uploading the files via FTP and adding the entry in phpmyadmin. In addition, I’m sure there were tons of PHP bugs and security holes that I had in the old script. The old theme was also badly coded with many HTML errors and many Wordpress incompatibilities.

Reversing the Xperia Play emulator (part deux)

The last time we spoke, I managed to run any PSX game on the Xperia Play by redirecting some function calls. Well, since then Sony (you could say) fixed it (still don’t know how, I should look into it one day, I’m guessing they revoked the certificates for Crash Bandicoot) and people running Android 2.3.4 on the Xperia Play can’t use PSXPeria anymore. I’ve re-patched it a while ago, but never got the chance to modify the patching tool to use the new method (I really hate Java and don’t want to use it, so I held back.) until today. As customary to my releases, I will begin by telling more than what you want to know about how it works.

Analyzing Kindle 4.0

Well, Amazon might as well have stolen my wallet, because I am going to lose a couple hundreds of dollars. However, what fun is a Kindle if we can’t run our own code? (Answer: still pretty fun, but that’s besides the point.) Anyways, I haven’t gotten my hands on the new Kindles yet, but I got the next best thing: a software update from Amazon (http://www.amazon.com/gp/help/customer/display.html/?nodeId=200774090)

Installing Windows 8 Developer Preview (8102) on a USB Drive (Windows To Go/Portable Workspace)

This really isn’t some technical or hard to do thing, but it’s a cool little trick I found that I haven’t seen mentioned before. If you don’t know what “Windows To Go” (previously “Portable Workspace”), watch this video from the Build 2011 conference. Basically, it allows you to install a full copy of Windows 8 onto a USB drive/external hard drive and use it on any computer that supports USB booting. Your settings, files, programs, etc go where-ever you go. The feature is in Windows 8 (and the developer preview), but the program to make the drive is not. Luckily, an old leaked build has the program, but you can’t just copy and paste it, it won’t run. Instead, follow the directions below to get Windows 8 installed to a USB drive. (I used a virtual machine to do the following, therefore I did not need to burn any DVDs. I will give the directions assuming you’re using a real computer though).
