If you have a printer attached to a Linux machine, you can easily send print jobs to that printer from another remote computer using Dropbox (see similar solutions for Windows and Mac).
The idea is that you create a shell script to monitor a local Dropbox folder. As soon as a new file is added to that folder from a remote computer (or mobile phone), the script will send the file to the attached printer. Once the the printing job is completed, the file is removed from the incoming queue.
The implementation is easy. Kurt Granroth sent me this improved* shell script that you can use in any Linux environment. You only have to setup a cron job against this script such that it runs after every ‘n’ seconds (or minutes).

Facebook is rolling out a new security feature that lets users log out of their accounts remotely from another computer.

To do this, go to "account settings" on your Facebook page and click on "change" next to "account security." There, you'll see where else your Facebook account is logged in, including the type of device and the city it's in or near. To log out of any of them, click "end activity."

Facebook is making this available over the next couple of weeks. It will be accessible on computers, but not mobile devices.

The feature is similar to what Google Inc.'s Gmail offers to its users, and Facebook says it's designed to help users keep their logins secure.

When you want to establish an Online business the first thing you need is a Website for your venture. For a website, the first thing you need is some Online Web Hosting Space and skilled professionals who can create a proper website for you. But what are the things you should keep in mind while selecting the best web host? What are the most common misconceptions while deciding the best web host?

Unlimited Web Hosting and bandwidth means no worry
Most users are tension-free that their unlimited hosting account will help them enjoy a tension free life. But, most Unlimited hosting accounts do no guarantee unlimited disk usage. The more processing that takes places on the server may cause problems for your website as your Disk Usage takes place (can be understood as Processing usage)

Shared hosting and dedicated hosting are similar
Most users have a misconception that shared and dedicated hosting servers don’t really make a difference. Just imagine that another website which is hosted on your shared server used up all the processing power or gets infected by any malicious software, then what? You may loose all the precious data on your site and may also cause a lot of problems. A dedicated server would be your personal server and may allow you to do anything at the expense of your own site. So, if you mis-manage something, then you are responsible for your own actions as others are no way related to you.

All cheap web-hosting services are unreliable
Everyone wants to use the Best Web hosting services, but most people are not on a big budget, so they keep looking for cheap options. But it is a misunderstanding that all cheap web hosting services are unreliable, there are many web hosting services which give you the service at affordable rates and they are very reliable too.

Any website can work on any type of server (without any issues)
Web hosting server is not your requirement! A PROPER hosting server is your requirement. So you must first ensure that the package which the hosting provider is giving you fits your needs. For example: Its a tiresome job to make the .NET framework to work on Linux based servers. It may take up your valuable time and may even land you into trouble. Most people do not think before purchasing a hosting package and then repent over it.

Good hosting providers don’t have any problems/issues
This is the biggest misunderstanding. You can face web hosting issues with any hosting provider, its just the service each provider delivers which makes them expensive and good. If your site is not properly protected from outbound access, then it can be hacked. You cant blame your provider for that.

Also, most web hosting companies allow affiliate sales, which can help you to earn some cash fast by referring their service to others. Many companies also allow the Web Hosting Coupon system, which can help you give discounts to people whom you refer.

It's far from an Oscar, but landing atop McAfee's annual list carries a distinction all its own: It means that criminals believe those celebs are the perfect lures to sucker people into visiting malicious websites.

Here's how can view and work on your own desktop from any corner of the world.

Then

Goto StartMenu->Control Panel->Administrative Tools-> Local Security Policy->Local Policies->Security Option->Accounts:Limit local account use of blank passwords to console logon only->Disabled

Now connect Remote Desktop without password.

You are done with it............Enjoy

When you are making some changes to your system settings, wouldn’t it be great to see what is actually changing in the registry? This would be really helpful when the changes you have made doesn’t work as expected and you want to reverse the changes but can’t without actually editing the registry.

Here is how you can track what exactly gets changed in the registry.

1. Start Regedit
2. Select the top level (Computer).
3. On the menu select File>Export and save the file to any location. However, I would recommend saving the file to root of any drive (C, D etc). You can name the file ‘before’.
4. Make any change to your system.
5. Go back to Regedit and press F5 to refresh it.
6. Repeat step 3 and export the registry once again and save it in the same directory as before. This time name the file as ‘after’.
7. Open up a DOS window (Command prompt)
8. Go to the drive/directory where you saved the two exported file.
9. Enter the command fc before.reg after.reg > diff.txt.
10. The output file (diff.txt) will contain the changes made to the registry.

Muslims generally use the term "Halal" to designate food items that they are allowed to eat under the Islamic law (like fish). The opposite of "halal" is ‘haraam’, another Arabic term which is used for food products that Muslims are forbidden from eating (like pork).

This page describes in detail how stuff is classified as Halal or Haram according to Islam. And its not just about food, the term Halal can refer to any action that is permitted under the Quran while prohibited actions are known as "Haram".

A Search Engine for Muslims (and your Kids)

Extending the Halal and Haram concept to the Internet, Ramadan Kareem has created a search engine called I am Halal that might just prevent you (Muslims and Non-Muslims alike) from "accidentally" bumping into any explicit (or "Haram") content on the Internet.

Unlike Safe Search in Google which simply removes all adult sites from search results, I-Am-Halal, which uses search results from Yahoo, employs a double-layered filter.



When you type a search query (e.g. sex) that can potentially retrieve "haram" search results, the search engine would require you to confirm whether you really want to see those search results. When you say yes, it will fetch the relevant pages but will still filter out content that is not deemed as family-safe.

The search results page will also contain thumbnail images of web pages alongside the site links and description. And in addition to websites, you may also use IAmHalal.com to search for images and news stories on the web.

I am actually quite impressed with "I Am Halal" and, other than the religious side of things, this is something good for your kids as well. For instance, if they type a query that is bound to return explicit results, the search engine would simply refuse to work for that query.

Before getting into the actual process, let’s look at a couple of real-world situations that explain why you may want to turn your home computer into a web server.

Situation #1. Say you have music MP3s, documents and other important files on the hard drive of your home computer. If you turn this home computer into a web server, you will be able to access all these files from office or any other Internet connected machine including your mobile phone.

Situation #2. You have some personal photographs that you want to share with other family members. You can either upload these pictures online to a site like Flickr or better still, just convert the computer into a web server. Now you can connect the camera to the computer, transfer the digital pictures to some designated folder and they’ll instantly become available to your friends and family anywhere in the world.

Situation #3. You want to host a website on the internet but the web hosting jargon like FTP, DNS, etc. is way too complex for you. The workaround therefore is that you setup a web server on your home computer (it’s easy) and then host a website in seconds without spending a single penny on external web hosting services.

Now if any of the above reasons look convincing enough, here’s how you can convert your Windows, Mac or Linux PC into a web server in less than two minutes - no technical knowledge required.

Go to labs.opera.com, download the Opera Unite software and install it. Congratulations, you are now running a web server on your machine and just need another minute to configure local file folders that you want to share with others over the internet.

Here’s an illustrated screenshot of the configuration panel - nothing technical here again.

Start the Opera Web browser (yes, that’s also you web server now) and enable the Opera Unite service from the lower left corner. Now double click the File Sharing link and select the folder whose content you want to share on the web. Any file or folder inside this folder can now be accessed over the internet - you can either use a public URL or specify a password for private sharing.

The following screencast video has more detailed instructions on how to get started with Opera Unite or you may refer to the User Guide if you get stuck somewhere.
Opera Unite looks pretty useful but there are other services around that can also do pretty similar stuff. For instance, both PurpleNova and Dekoh Dekstop enable users share content on the Internet directly from the hard drive without having to upload it anywhere.

Update: It’s important to note that your computer must be in running state and also connected to the Internet for others to download files and web pages since Opera Unite streams content directly from your machine - it doesn’t upload or caches anything to its own servers.

The standard Google Translation service is pretty good for translating documents that exist on the web but if you ever need to translate Word files that reside on your local hard drive, the translator toolkit will come in handy.

It’s an online service where you can upload Word Documents or text files and translate them from one language to another instantly.
The document formatting is more or less preserved and you can download the translated files to your desktop in their original format like Word, OpenOffice or HTML. Unlike regular Google Translation which is read-only, here you also have the option to edit the translated version of the document in the browser itself.

The only condition is that the size of these individual documents, that you intend to upload for translation, should not exceed 1 MB.

1. Use the full version of Bing

If you are using Bing outside North America, chances are that you seeing a localized version of Bing that may be missing some features. For instance, the Indian version of Bing.com doesn’t have search history and the image on the Bing home page here is not interactive as in the US version.

To explore the full version of Bing, go to this page and set English - US as your default region. You can now enjoy all the Bing features from anywhere.

2. Track Companies from the IE Favorites Bar

If you search for a company stock (e.g. GOOG or MSFT), Bing will automatically create a web slice for that company which you may then add to IE 8 and track the performance directly from the favorites bar. You need Internet Explorer 8 to try this feature.




3. Watch Preview of Hulu Videos outside US

Hulu hosts some popular popular TV shows but the problem is that you can only watch these videos if your computer has US based IP address.

However, Bing lets you watch shot previews of Hulu video even outside US. Just search for any TV show episode on Bing Videos (see example) and hover the mouse over any of the video thumbnail to watch a short clip.

4. Save and Email search results

With Bing, you can save your search history on to a local folder inside Bing or to your Windows Skydrive account. Alternatively, you may send your search queries to a friend via email or publish them on your Facebook wall via Bing. You’ll need Silverlight to share queries in Bing.

5. RSS Feeds of Search Results

Unlike Google or Yahoo, Bing offers RSS feeds for their web search results that you can subscribe to inside any feed reader. Your browser should be able to auto-detect the RSS feed of Bing pages or you can append &format=rss to any Bing search URL and convert it into a feed.

This RSS feature is not available for Image or Video search in Bing.

6. Find Pages That Link to MP3 Files or Documents

Bing (and Live Search) supports a unique "contains" search operator that lets you find web pages that contain links to particular file types.

For instance, a search like susan boyle contains:mp3 will show pages that are about the British singer and that also link to MP3 files. Replace mp3 with doc to search pages that contain links to Word Documents.
