News: ATI Catalyst Drivers 10.2 Released. No Fedora 12 Support.

After almost a month, ATI has come up with a new version 10.2 of its Catalyst (fglrx) drivers. The drivers can be download from ATI Catalyst™ 10.2 Proprietary Linux x86 Display Driver Page. As AMD is famous for doing nothing but just incrementing versions of there software, even this version doesn’t support xorg-1.7.4. But if you still want to give it a try, you can download and try installing the driver. Otherwise mesa-experimental drivers are your friend. Checkout the post Fedora 12 and ATI Drivers and save yourself from frustration 🙂

And yes, lets wait for next version of ATI Drivers 🙂

 

Javascript To Remove All Facebook Apps From Your Account

This is a guest post by Gaganpreet Arora AKA bitgeek.

My Facebook app list was cluttered with useless apps accumulated over the time I had joined Facebook. The worst thing is that Facebook does not allow you to remove multiple apps in one go. You have to select one, confirm on “Are you sure?” first and then click on “Okay” when it is deleted. Very cumbersome. So I wrote a Javascript hack to remove all of the apps in one go.

Warning: This will actually delete all the apps

Step 1

Go to: http://www.facebook.com/editapps.php?v=allowed.

Step 2

Select and copy the complete code below and paste it into the address bar.

javascript:
function postwith (to,p)
{
  var myForm = document.createElement("form");
  myForm.method="post" ; myForm.action = to ;
  for (var k in p)
  {
    var myInput = document.createElement("input") ;
    myInput.setAttribute("name", k) ;
    myInput.setAttribute("value", p[k]);
    myForm.appendChild(myInput) ;
  }
  document.body.appendChild(myForm) ;
  myForm.submit() ;
  document.body.removeChild(myForm) ;
}
 
function getElementsByClassName(classname, node)
{
  if (!node)
  {
    node = document.getElementsByTagName('body')[0];
  }
  var a = [], re = new RegExp('\\b' + classname + '\\b');
  els = node.getElementsByTagName('*');
  for (var i = 0, j = els.length; i < j; i++)
  {
    if ( re.test(els[i].className) )
    { a.push(els[i]); }
  }
  return a;
}
 
var arr = [];
els=document.getElementsByClassName('app_row');
arr['fb_dtsg']=document.getElementsByName('fb_dtsg')[0].value;
arr['remove'] = 1;
arr['post_form_id_source']='AsyncRequest';
arr['post_form_id'] = document.getElementById('post_form_id').value;
arr['app_id']=els[0].id.replace("editapps_allowed_","");
arr['__a'] = 1;
for (i=0; i

Press Enter.
 
The browser may get stuck for a few moments if the list is large, so if it does, just wait a bit and it will respond back.

News : ATI Catalyst Drivers 10.1 Released. Test them now!

After a long, really long wait, AMD has released the next version 10.1 of its ATI Catalyst display drivers (fglrx) for Linux. The drivers can be download from ATI Catalyst™ 10.1 Proprietary Linux x86 Display Driver Page. As previous version turned out to be a big turn off for Fedora community and AMD took a long time for releasing this, I hope they have fixed issues regarding new Xorg version. Fedora folks will really want this version to work, otherwise there will be *blood* 😀 You have got AMD graphics card? What are you waiting for? Download the drivers immediately and test the damn thing! And please let everyone know whether it works for you with details of your graphics card. You know where the howto for installation is ;) How To: Install ATI Catalyst (fglrx) Drivers.

I really hope that things turn out well and you don’t really get to this point. But if these drivers don’t work for you, proceed to the post Fedora 12 ATI Catalyst Drivers and checkout mesa-dri-drivers-experimental.

Tip: Multiproxy Switch : Easily use multiple proxies in Firefox

A lot of people (especially working people with mobile devices like notebook/netbooks) need to use different proxy servers at home and office. There are several Firefox extensions available to achieve the required functionality but IMHO Multiproxy Switch(Mozilla Addon Page) is the best because

  1. Its simple and easy to use. It does what it should. No fancy/extra terrestrial stuff. Just switch proxies 🙂
  2. Easy and Firefox like interface to specify different proxies. Many extensions add their own fancy interfaces for specifying proxies which eventually suck big time.
  3. I am a fan of this one. The No-Proxy list. I could never understand those regular expression based no-proxy lists in FoxyProxy. Multiproxy Switch has Firefox like No-Proxy list which rocks and understandable 🙂

If you happen to come across a better proxy switcher for Firefox, do let us know 🙂
