Fresh from the Labs
This clever little script runs on anything that has a Net connection and Perl. It grabs MP3s from a MySpace page and saves them locally. Like youtube-dl, this is not new, but it automates a number of things and does it locally from your hard drive without weird requirements. The best part is that it grabs all the songs and saves them in the format of [band] - [song title].mp3 automatically. Like youtube-dl, simply save the project file to your hard drive and flag it as executable, like so:
$ chmod u+x getmsp3
Now, simply run the script and enter the URL of the band you want after the command:
$ ./getmsmp3 http://www.myspace.com/soundskp
Of course, we can't encourage you to download illegally, so I've provided you with the URL of our own band, which you're welcome to download (slightly redundant though, as we've provided the option to download our files anyway).
Here's a project I'm dying to see the outcome of—a free (as in beer) speed camera warning system designed to run across a large range of mobile phones and GPS devices. FoxyTag is a collaborative system designed to encourage users to share speed camera data—the more users and feedback, the more reliable the system becomes. The system doesn't merely assume a speed camera is in one place either. Users have the options to report a permanent camera or the installation or removal of a mobile camera.
However, Michel Deriaz, the project's leader at Geneva University, isn't trying to promote speeding or unsafe driving. According to FoxyTag's Web site:
FoxyTag motivates neither speeding nor any other risky behavior, but allows drivers to concentrate on the road instead of having their eyes fixed on the speedometer, by fear of being flashed. We observe that drivers tend to brake suddenly when they see a speed camera (even if they are not speeding), which can provoke traffic jams or even accidents (chain collisions or slidings, like in this video [see the Web site for the link]). FoxyTag signals in advance the presence of speed cameras, so that drivers have enough time to check their speed and adapt it if necessary.
As for mobile phones, any Java mobile phone with MIDP 2.0, CLDC 1.1 and Bluetooth should be compatible. For GPS systems, any Bluetooth GPS should be compatible (including GPS modules of some navigation systems), and Michel recommends a Sirf III GPS. Unfortunately, I have neither. Hopefully, we can rustle up the needed hardware and cover this project further. I'd love to see the results of this one.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
