Almost every evening, between 8:30 and 10:00, my Wi-Fi just dies. This, in itself, could be explained by a crappy Wi-Fi source or some hardware failure, except that I know both of my neighbors are experiencing the same loss of signal at the same time. While the Wi-Fi is down, the LAN is OK, and anything plugged into Cat5 can access the Internet just fine. One possibility comes to mind — perhaps some other neighbor arrives home and turns on their router from 8:30 to 10:00? And something in their signal is hosing our Wi-Fi? I have tried looking around for software to help identify the source of interference, but either the programs are ridiculously expensive for a home user, or else my card (Intel Link 1000 BGN) isn't supported. (Netstumbler is an example of the latter.) Any suggestions on how I can track this down?

Appleseed aims to create an open source, fully distributed and decentralized social networking software.

Appleseed is still in active development. When it's done, you'll be able to pick an Appleseed compatible site, sign up, connect with friends, send messages, share photos and videos and join discussions. And if you decide you don't like the site you're on, you can sign up for another Appleseed compatible site and immediately reconnect with everyone in your network.

In a paper presented earlier this week at the Usenix Workshop on Large-Scale Exploits and Emergent Threats, the researchers demonstrated how they used the technique to continuously spy on BitTorrent users for 103 days. They collected 148 million IP addresses and identified 2 billion copies of downloads, many of them copyrighted.

The researchers, from the French National Institute for Research in Computer Science and Control, also identified the IP addresses where much of the content originated. They discovered the the vast majority of the material on BitTorrent started with a relatively small number of individuals.

In computer networking, the term quality of services (QoS) describes resource management rather than the quality of a service. Quality of services implements control mechanism to provide different priority to different users, applications, and data connections. It is used to guarantee a certain level of performance to data resources. The term quality of service is often used in the field of wide area network protocols (e.g. ATM) and telephony (e.g. VoIP) but rarely in conjunction with web applications. mod_qos is a quality of service module for the Apache web server implementing control mechanisms that can provide different priority to different HTTP requests.

Diaspora aims to be a distributed network, where totally separate computers connect to each other directly, will let us connect without surrendering our privacy. We call these computers ‘seeds’. A seed is owned by you, hosted by you, or on a rented server. Once it has been set up, the seed will aggregate all of your information: your facebook profile, tweets, anything. We are designing an easily extendable plugin framework for Diaspora, so that whenever newfangled content gets invented, it will be automagically integrated into every seed.

Now that you have your information in your seed, it will connect to every service you used to have for you. For example, your seed will keep pulling tweets and you will still be able to see your Facebook newsfeed. In fact, Diaspora will make those services better! Upload an image to Flickr and your seed can automatically generate a tweet from the caption and link. Social networking will just get better when you have control over your data.

Let's say your site is becoming a big success and as a result it's becoming slower and slower. There are several things you do without buying additional hardware:

No moment in technology history has ever been more exciting or dangerous than now. The Internet is like a new computer running a flashy, exciting demo. We have been entranced by this demo for fifteen years. But now it is time to get to work, and make the Internet do what we want it to.

Using just open source tools and a few tweaks, it is possible to detect and block suspicious login attempts.

Google thrives where privacy does not. If you're like most internet users, Google knows more about you than you might be comfortable with. Whether you were logged in to a Google account or not, they know everything you've ever searched for, what search results you clicked on, what news you read, and every place you've ever gotten directions to. Most of the time, thanks to things like Google Analytics, they even know which websites you visited that you didn't reach through Google. If you use Gmail, they know the content of every email you've ever sent or received, whether you've deleted it or not.

GoogleSharing is a system that mixes the requests of many different users together, such that Google is not capable of telling what is coming from whom.

YoutubeFS enables you to browse your favorite Youtube videos locally on your desktop without going to the youtube website. Just create a youtube account and add videos to your playlists, favorites list or subscribe to different channels. YoutubeFS then enables you to automatically load these videos to a local folder on your desktop. You can then view these videos (using a browser) as if they are local files.
