How To Browse the Web Faster on a Slow Internet Connection

If your current Internet speed is very slow and you are living in an area where broadband connections are still not available, here are some ideas to help you download web pages faster on your computer. You may use the same tips to  improve your web browsing experience on a sluggish USB modem.

Surf the Web Faster on Slow Internet


1. Turn off web images, the Adobe Flash plug-in, Java Applets and JavaScript from your browser settings as these files are often the bulkiest elements of any web page.

2. Increase the size of your browser cache. If the static parts of a site (like background graphics, CSS, etc) are stored in the local cache, your browser can safely skip downloading these files when you re-visit the site in future thus improving speed.

3. Sometimes the slow DNS server of your ISP can be a bottleneck so switch to OpenDNS as it can resolve website URLs into IP addresses more quickly. If you aren’t too happy about OpenDNS redirecting your Google queries, follow this simple hack.

4. Finch can serve a light-weight version of any website in real-time that is free of all bells and whistles. For instance, the New York Times homepage with all external resources can weigh more than a MB but Finch trims down the size by 90% so the site loads more quickly on a slow web connection.

5. Flinch (mentioned at #4) is good for reading regular websites but if you just need to check the latest articles published on your favorite blogs, use BareSite. This service will automatically detect the associated feed of a website and render content quickly inside a minimalist interface.

6. The Google Transcoder service at google.com/gwt/n can split large web pages into smaller chunks that will download more quickly on your computer (or mobile phone).

7. Monitor your Internet speed to determine hours when you get the maximum download speed from the ISP. Maybe you can then change your surfing schedule a bit and browse more during these "off peak" hours.

8. You can use a text browser like Lynx or Elinks for even faster browsing. It downloads only the HTML version of web pages thus reducing the overall bandwidth required to render websites.

9. When searching for web pages on Google, you can click the "Cache" link to view the text version of a web page stored in the Google Cache. Alternatively, install this GM script as it adds a "cached text only" link near every "Cached" link on Google Search pages.

10. Move your web activities offline as far as possible. You can send & receive emails, write blogs and even read feeds in an offline environment. Also see: Save Web Pages for offline reading.

11.  You can interact with websites like Flickr, Google Docs, Slideshare, etc. using simple email messages. Uploading a new document to Google Docs via email would require less bandwidth than doing it in the browser because you are avoiding a trip to the Google Docs website.

12. Applying the same logic, you may also consider using tools like Web In Mail or Email The Web as they help you browse websites via email. Just put the URL of a page (e.g., cnn.com) in the subject field of your email message and these services will send you the actual page in the reply.

13. Bookmarklets are like shortcuts to your favorite web services. You neither have to open the Gmail Inbox for composing a new email message nor do you have to visit Google Translate for translating a paragraph of text. Add relevant bookmarklets to your browser bar and reduce the number of steps required to accomplish a task.

14. Use the netstat command to determine processes, other than web browsers, that may be secretly connecting to Internet in the background. Some of these processes could be consuming precious bandwidth but you can block them using the Firewall.

15. Use URL Snooper to determine non-essential host names that a website is trying to connect while downloading a web page. You may block them in future via the hosts file or use Adblock Plus to filter out advertising banners on web pages.

16. If you don’t want to spoil your web surfing experience by stripping images and other graphic elements from  a web page, get Opera Turbo. It will first fetch the requested web page on to its own server and then send it to your machine in a compressed format. Opera Turbo won’t change the layout of a web site but can lower the image resolution so that they load faster on slow Internet.

17. Change the user agent of your desktop browser to that of a mobile phone like Apple’s iPhone or Windows Mobile. This will help you browse certain web sites like Google News, WSJ, etc. much faster because they’ll serve you a light-weight and less cluttered mobile version of their sites thinking you’re on a mobile phone.

Get an Email Alert [ with Picture ] When Someone Tries to Log into your Computer

You have a feeling that someone else used your computer (or at least made an attempt to login) while you were out for a quick coffee break. Maybe that colleague with whom you share the cubicle knows your password or he made a few guesses before finally giving up.

How do you get notified when such an attempt is made to intrude into your computer?

A new website (made in Turkey) called MouseLock.co may have a simple solution here. They will send you an email alert as well as a picture of the intruder as soon as someone tries to use your computer.

Here’s how Mouse Lock works.

You sign-in with your Google Account (they’ll send the alert to your Gmail address) and then select a secret pin on the screen. Next, put your mouse cursor in a designated area on the Mouse Lock website and leave the machine.

Now when someone moves the mouse, they will also have to enter the original pin. If they fail to do that in the first few seconds, Mouse Lock will send you an email and, if the computer has a webcam, it will use that to also snap a picture of the intruder.

Mouse Lock won’t prevent the intrusion but will at least notify you the minute it happens. And best of all, this a web app and thus requires no installation.

Internally, the site uses jQuery (mouseLeaveEvent) to detect mouse movements while the webcam photographs are captured using the getUserMedia() API currently supported in Chrome and Firefox. The alerts, possibly due to a bug, are triggered even when any of the keys are pressed and that makes it a little less useful since there’s no way to lock the computer after setting up the monitor.

Transparent 3D computer debut

Transparent 3D computer unveiled


18729835.cms
A transparent computer that allows users to reach inside and touch digital content has been unveiled at the Technology, Education and Design (TED) conference in Los Angeles.


TED fellow Jinha Lee has been working on the SpaceTop 3D desktop in collaboration with Microsoft.


Allowing people to interact with machines in the same way they do with solid objects could make computing much more intuitive, he told the BBC.


He can see the system coming into general use within a decade.


The system consists of a transparent LED display with built-in cameras, which track the user's gestures and eye movements.


The design was inspired by what he sees as a human need to interact with things.


"Spatial memory, where the body intuitively remembers where things are, is a very human skill," he said.


Translating this to the digital world will enable people to use computers more easily as well as complete more complex tasks.


"If you are working on a document you can pick it up and flip through it like a book," he said.


For more precise tasks, where hand gestures are not accurate, there is a touchpad. It will allow, for example architects to manipulate 3D models.
