Over the past year, my SSD’s performance became really bad. To a point where my boot times went from 8 seconds to 30 seconds.
If you want to recondition your drive, you want to zero your drive out. If you’re using Windows, use SDelete: http://technet.microsoft.com/en-us/sysinternals/bb897443
On Mac, you can easily do this in Disk Utility.

In one of my engineering classes, I heard a student say:
“…I’d rather memorize things then think harder about it.”
It is kind of depressing because engineers are supposed to think about how to approach a problem and to solve it using the skills and knowledge we obtained. Without thinking, engineers would be more… paper pushers rather than problem solvers. People...

I was very surprised that a lot of people actually used my data for Nextbus and Dining Menus during the HackRU event.
If you’re still interested in using them, you can always find the documentation here: http://jla.rutgers.edu/~sjlu/rutgers_oss_apis.html

DisplayLink & Linux
Now, there’s a lot of stuff that’s already out there. However, there wasn’t much detail on how to get my two monitors working alongside with my DisplayLink monitor.
Here’s how I finally got it working:
Make sure you build these packages: build-essential xorg-dev libusb-dev git-core

Facebook Third Party IDs and SuperRewards
If you don’t already know, Facebook has been trying to secure their data more and more these days by implementing OAuth and anonymity.
So, if you don’t know what’s going on, I’m gonna briefly describe it since SuperRewards and Facebook don’t give any good documentation at all on this topic.
It used to be like this. [your user id] from Facebook -> [your user id]...
Linux terminal fonts ported to Windows →
I hate Windows so much, but it’s the only way I get to play games. If you’re using PuTTY and you hate the stock fonts, use these.

Music App Migration
In the next couple of days this week, Music will undergo another server migration to save costs. The reason for this is because we’re not driving enough traffic into the application anymore due to the changes Facebook has made to profiles and more.
We will also be integrating bandwidth controls where a user’s playlist that drives way too much traffic (more than 30 req/hour or 1 req/2...

If you’re using MySQL 5.0.X, you’ll most likely be encountering this bug if you’re database is hanging and/or crashing. Basically, if you’re using “INSERT DUPLICATE”, you’ll need to upgrade to 5.1.X. If you’re using Debian, use “lenny-backports”.

Karnaugh Maps & Static "1" Hazards
The above shows a static hazard. Basically, when two groups are not interconnected, then we have one variable where that one gate depends on the direct input while the other depends on a inverter.
Because we are assuming this in a “real” case, we can assume each gate or inverter (logic), requires 10ms to respond. Therefore, when the variable changes, the one gate responds 10ms...
Caching in Titanium SDK
If anyone is using Titanium’s SDK to develop iPhone applications, here’s a nice script for you to use to pull data in and out of cache and compare timestamps on the file. This is also very useful if you’re experiencing issues with Titanium’s getModificationDate().
When using write_cache, make sure the data you are inputting is in some text format and not an array...
