Wireless: Data Transmission

We are using Wireless# Guide to Wireless Communications by Jorge Olenwa and Mark Ciampa.  The pictures on here are screen clippings from either the book or the power points that my instructor is using. 

This first post is two classes combined.

Notes and stuff after the break

Routing/Switching: Review Notes

**All notes with the CSIT 2750 Routing/Switching tag and labeled R/S are derived from Nathawat Laxman's classes.  If you wish to use any of these notes, you must give credit to him, as this is his work, not mine, not something out of a textbook** 

Most of this is going to be a review of my notes from the Network Fundamentals class.  Over time, I may add links to videos on subnetting as well.

More after the break

I'm Baaaack!

So after some thinking (scary, I know) I think I am going to expand on this blog a little.  I think what I am going to do is share my class stuff from at least Routing and Switching and the Wireless classes I am taking this semester.  I am also taking Java, but am probably not going to be doing much on that here, as its mostly stuff I don't really understand.  So, look for some changes, don't be alarmed when things are being shuffled around. 

LAST NEWS OF THE SEMESTER!!!!

YES!  It's TRUE!  Last class meeting of the semester, and this news is it!

VMware Source Code Stolen and Posted Online

Right now the company says that the impact should be minimal, since what was stolen is one file from....

..... 2003 or 2004.

The code was stolen from a Chinese company in March.

So, if you use VMware, review your security for your virtual environments.  That's all you can do for now since very little is known about what the real impact will be.

Security News 4/19

CISPA, if you have not heard, is the new PIPA and SOPA.  But you know its bad when the White House says something along the lines of "uh, this isn't the greatest idea".

White House raises concerns over CISPA bill

In a nutshell, this bill would allow ISPs to monitor you- and gather any information that they want to on you if they feel you are a threat. Not too outside the realm of how it works now, but there is NOTHING written in the bill that would keep them from accessing your private emails, chats and Facebook posts.  All they would have to say is "cybersecurity threat!!!!" and off they would go.

The idea behind the bill is sound, but I want my freaking private stuff kept private.  It's none of anyone's business if I want to send my husband a dirty email. >.<

Security News for 4/12

Yes, I know that I have not been keeping up with this very well.  As soon as I get all my papers written for other classes, I plan on going back and filling in the gaps.

Today's post, however, is for Thursday's class.  While searching for our weekly news article, I stumbled across this little gem:

Hotel's Free Wi-Fi Comes With Hidden Extras

Basically, this hotels' ISP is injecting code into every website you visit that is supposed to show whatever ad they want you to see- regardless of what's supposed to be there, and without the knowledge of both the user and the page creator.

Now, imagine if that particular coding got hacked.  Yeah.  That's some scary shit right there.
