Electonic Flashcards with Excel

Submitted by dcheeseman on Tue, 05/08/2012 - 19:11

Throughout my training pipeline in the Navy I have played with different techniques to streamline my notetaking and review.  During OCS and SOBC, I was lucky enough to have computer access and was able to use Excel to make flash cards.  There are many templates for flashcards out there, but I wanted an electronic system that didn't require printing out the cards and gluing them together and one that would facilitate effective review without unecessary review of material that is already known.

Java & Gmail Based Secret Santa Mailer

Submitted by dcheeseman on Sun, 12/12/2010 - 23:53

This is a simple Secret Santa organizer which uses JavaMail and GMail SMTP to send out Santa-Assignments.  I designed it so that I could simply type a bunch of information into a text file and have it automatically send out the emails rather than me being omniscient as to who's getting what, including who's gifting me.
 
The JAR is self-executing and contains the JavaMail API inherently, so just put it on your desktop and double click it.  It will then ask you for a file which contains the configuration information.  The configuration should look something like this:

CPU Throttling In Windows XP

Submitted by dcheeseman on Sun, 08/09/2009 - 02:40

So my fan on my laptop started making a horrific racket (possibly because my laptop has been on nearly half of its existence) so I found a way to clock the CPU down so the fan wouldn't need to be on. Here are the commands I used.

Performance Script:

powercfg /CHANGE PowerConfigName /processor-throttle-ac ADAPTIVE

powercfg /CHANGE PowerConfigName /processor-throttle-dc ADAPTIVE

Apple - Just Another Computer

Submitted by dcheeseman on Fri, 07/24/2009 - 16:03

What I'm trying to say in this article is that Mac's for all their hype are just another FUCKING computer with a bigger price tag. All you're effectively paying for is branding and maybe a little extra engineering. However, this price discrepancy amounted to around $325 dollars when warranties weren't considered and you have to ask yourself if Mac's are $325 better engineered than a PC.

SSH Slow?

Submitted by dcheeseman on Sun, 06/07/2009 - 00:16
SSH  slow and seemingly not responding?  I recently had this issue and was surprised at how common it was.  To further add to the litany of solutions, I figured I'd repost it again.  If your ssh seems slow ESPECIALLY right after submitting the password, add this line:
UseDNS no
to the file:
/etc/ssh/sshd_config
This happened to me (and likely others) because I switched to a static IP on my local network so I could reliably forward the ssh port to the right computer.  With a dynamic ip, most routers send the hostname to your computer, but when y

Simple Encryption Algorithms

Submitted by dcheeseman on Tue, 04/14/2009 - 18:06

Here are a couple simple encryption programming examples.  Obviously these are full of exploits so you wouldn't want to use them seriously, but they are great for teaching students about the basic idea of encryption.

Disable the Windows System BEEP

Submitted by dcheeseman on Mon, 06/30/2008 - 21:53

At any rate, after a good solid minute of beeps and at least 45 seconds of shocked/amazed/irritated looks from the other patrons, I managed to disable the system beep and got a light applause from someone in the back of the Cafe amongst a myriad of grumbling. In case you have not clicked on the link I'll describe the basic steps:
