Make Your Linux Desktop Look Like A Mac - Mac4Lin

Do you want to give your desktop a pinch of Mac OS X? Do you want to change your GNOME desktop from the default look to something likemac4lin-documentation_html_m2ad3b0cf.jpg this? Use Mac4Lin to give it the look and feel of Mac OS X (latest being 10.5, Leopard) on *nix GTK based systems.

Make this happen by Using Mac4Lin on your Linux system. I use Ubuntu  and it worked awesome. The only thing I could not get is  the icons at the bottom, apart from that I have got the perfect MAC look for my Ubuntu system. 

Here is a nice tutorial on how to go about on Howtoforge and also the Mac4Lin has nice documentation.

Don't forget to thank the owner. Its an amazing piece of work.

Download all the 3 parts.

Hacking the Free “La Fonera” Wireless Router

wertarbyte writes,
 
"FON is still giving away their wireless routers for free in Germany and Austria untilwifi_free.gif Wednesday — under the premise that the devices will be connected and used as FON access points.
The router, called 'La Fonera,' is a variant of OpenWRT, but locked down to prevent modification, including a signed firmware image to prevent the upload of new software. It is, however, possible to get shell access by connecting to a serial port present on the circuit board.
And now two students from Germany have discovered vulnerabilities in the CGI scripts used to configure the device, and successfully activated an SSH daemon on the device by exploiting them, giving owners a root shell on their router. They also provide a detailed description of the procedure and 'ready-to-use' perl scripts to open up your router."

Share Some Bandwidth, Get Free Wi-Fi - La Fonera

The La Fonera router attaches to a Time Warner broadband Internet connection and becomes a FON Wi-Fi access point that supports 802.11b/g wireless. The La Fonera router has two separate wireless channels, one a secure channel for the owner, and the other an open channel for other Time Warner users that are part of the shared network.

what is FON ?  

According to founder Martin Varsavsky, „FON is a global community of people who share WiFi connections. We call these people "Foneros", as a tribute to our heritage as a Spanish company. In order to become a Fonero, you go to FON, to download software that you install in your router, you place your antenna by a window and you share bandwidth with other Foneros from anywhere in the world. You can also buy the FON Ready router from our web site, plug and play. FON creates a free WiFi roaming environment for those who contribute WiFi signals, namely those who have already signed up with a local ISP and downloaded our software into their WiFi routers.”

The users may sign up to FON in three ways:

they can be Bills, Linus or Aliens. Strange isn't it ? The explanation is quite simple:

- A Linus (who are called like this after Linus Torvalds) shares his/her bandwidth for free with other Foneros,

- Bills (of course named after Bill Gates) share their bandwidth for a small fee.

- Aliens who don't share their bandwidth at all.

La Fonera router is secure out-of-the-box and offers two distinct WiFi channels. One channel is for the exclusive use of its owner; the second channel is shared with other Foneros. The La Fonera increases security through an encrypted private network and Foneros decide how much bandwidth to share. Public users cannot access the private network and there is no anonymous usage.

Hacker Cracks a Mac at Security Conference

A hacker managed to break into a Mac and win a US$10,000 prize as part of a contest started at the CanSecWest security conference in Vancouver.

The conference organizer decided to offer the contest in part to draw attention to possible security shortcomings in Macs. "You see a lot of people running OS X saying it's so secure and frankly Microsoft is putting more work into security than Apple has," said Dragos Ruiu, the organizer of security conferences including CanSecWest

The contest originally was open just to conference attendees, who were invited to try to break into the machines through a wireless access point. But on Thursday evening, 3Com Corp.'s TippingPoint division put up the cash prize and put the machines online so that anyone could participate.

The winner has not yet been named but is not someone attending the conference in Vancouver.

Cracking Google’s ’secret sauce’ algorithm

Oh! what a challenge..Make website Rank High on Google and get $10 million.google_search.jpg

The topic — Can a poker Web site rank high on a Google search using purely white hat tactics — meaning no spamming, cloaking, link farms or other frowned-upon "black hat" practices. Fishkin answered yes, provided the site also added other marketing techniques and attracted some media attention.

But one poker Web site owner was intrigued, and he later approached Fishkin. "He said, 'If you can get us a search ranking in the top five for online poker or gambling [using white hat methods], we'll buy that site from you for $10 million,'" recalls Fishkin, president and CEO of SEOmoz in Seattle. Intrigued but skeptical, Fishkin consulted other gambling site owners at the conference. "They said, 'If it really does rank there, we might be interested in paying you $10 million more.'"

If at all a single online gambling customer brings in at least $1,000 in revenue. With a recent Google search of "Texas Holdem Poker" yielding 1.64 million results, so there is no doubt that the site owners would pay millions to crack the code for Google's PageRank algorithm.

The poker owners would pay anything to get the Google PageRank algorithm cracked !

Hacking Ubuntu to Improve Performance

A nice article by Neal Krawetz on extreme tech on how to improve the performance of your Ubuntuhacking_ubuntu.jpg system. He speaks of fine-tuning of your system, about the understanding of the processes which are running,  and resource availability and process start up. Tweaking configurations, about how to disable undesirable processes, enable necessary housekeeping, and adjusting your kernel to better handle your needs to give you the best performance !

We know different versions of Ubuntu (and Linux) use different startup scripts and run different support processes.He nicely quotes :

 "Knowing how one version of Linux works does not mean that you know how all versions work".
 
While it is important to know what is running, it is even more important to know how to track down running processes and tune them to your needs.

View Deleted YouTube Videos with Delutube

Youtube must have neglected the fact that a site's contents can be retrieved very easily even after removing them from their visible list. This is precisely what Delutube has done. 

Delutube allows visitors to enter the video ID (pulled from YouTube) of a deleted clip, then attempts to retrieve the clip from YouTube's system. Clips are not completely deleted from YouTube's database at the moment they are taken down ( they remain in YouTube's cache before being cleared), allowing Delutube a chance of retrieving them. The site also allows for downloading of clips easily. They even have a random video for you on their site .

To view the deleted video, just enter the YouTube video id and Deltube may retrieve the deleted video for you from Youtube.

How to Remove Ads from Yahoo Messenger

I had done this loong time ago , but recently i started using yahoo messenger a lot and these adsyahoo-messenger-ads.jpg are really annoying . I got hold of a bat file which i had previously .The ads on yahoo messenger can be removed by running this .bat file. 

Steps :

- Logout Yahoo Messenger and exit it.

- Run .bat file

- Login Now and you are done ..

No more ads ! It works with the latest messenger too.. 

Condition:

You won't be able to enter the chat rooms, so if you use this feature, don't run the patch.

What happens when you run this .bat file ? 

The .bat file you've just downloaded edits most registry values related to the ads in Yahoo Messenger from HKEY_CURRENT_USER\Software\ Yahoo\pager\YUrl, replacing the data with a dummy asterisk. Here's the list of string values:

Messenger Adyahoo-messenger-no-ads.gif
Webcam Upload Ad
Webcam Viewer Ad
Webcam Viewer Ad Big
Webcam Viewer Ad Medium
Change Room Banner
Conf Adurl
Chat Adurl

If you install new versions of Yahoo Messenger, you will have to repeat the steps above, as Yahoo setup rewrites the registry entries.

Maybe Yahoo will make it still tougher to remove ads like this ..
