Punching holes into firewalls or "Why firewalls shouldn't be considered a ultimate weapon for network security" or "Secure TCP-into-HTTP tunnelling guide" Introduction Firewalls are heavily used to secure private networks (home or corporate). Usually, they are used to protect the network from: intrusions from outsidersmisuse from insiders In a TCP/IP environment, the typical corporate firewall configuration is to block everything (both incoming and outgoing), and give access to the internet only through a HTTP proxy. Still, this should not considered a ultimate weapon, and network administrators should not rely on the firewalls only. Encapsulation is the basis of networking. As soon as you let a single protocol out, tunelling allows to let anything go through this protocol, and thus through the firewall. This paper demonstrates how to encapsulate any TCP-based protocol (SMTP, POP3, NNTP, telnet...) into HTTP, thus bypassing the firewall protection/censorship (depending on your point of view) A word of warning: The problem

Experimental Real-Time Location Tracking Comes To Google Latitude On Android Google has just released a series of updates for their Google Maps Android application. Two of these updates are useful: Place page reviews and the ability to filter search results. But one of them is really interesting: real-time location updating in Google Latitude. To be clear, this feature is an experimental one that Google is trying out. But this new real-time feature is meant for short-term usage if you’re going to meet up with a friend, for example. Sounds awesome. This is all a part of Google Maps 4.6 for Android (1.6 and later).

Free Online Courses, Workplace Skills Training, Interactive Education and Multimedia Learning | ALISON The State of Location Analytics: Ventana Research DIY Ultimate Note-Taking Notebook This is sort of mid-range between what I do and a Moleskine. What I do: 1. 2. 2a. Cheaper than other systems, only takes a few minutes to accomplish, still includes removable paper for easy scanning, and no guilt for using a $20 notebook. I do this because I really can't justify the expense for note-taking. (I do carry a small Moleskine notebook, the cheap paper-bound one, for on-the-fly note taking). But, of course, I read Lifehacker religiously so, sooner or later, I'll try something like this.
Future of geo-spatial technology In 2020, the location-based service market is a $1.3 trillion industry.* In 2020, use of geo-location data, including GPS, generates $500 billion in consumer value Geographer jobs grow 35 percent per annum, while those of cartographers and photogrammetrists grow 22 percent between 2010 and 2020 Location becomes an integral dimension of data, allowing information patterns and decisions to be viewed through the lens of place.

How I Study... in an Organized Way I'm super crazy about organization. I'm no where near OCD, but anyone who knows me knows that I'm all about things being in order. Perfect example: my closet is organized by type of clothing and then organized by color. I'll go through this step by step. Syllabi Let's start with the syllabi. Once an assignment, test, or reading has been finished, I highlight it so I know that it's done and I don't need to worry about it anymore. Planner My planner is my sidekick during the semester. My planner, much like everything else in my life, is color coordinated. Moving On...... Here's how I get my weekly assignments organized so I can do them: I like lists. I pick a color for each subject, and make a list on a piece of notebook paper, the Stickies on my laptop, and organize my syllabi with the corresponding color flag tags. I've got to stop writing this post and get back to making a dent in my massive pile of work due at the end of this week!
