How to access blocked web sites from school, office, or work using JAP


Looking for a way to access blocked websites like Orkut, YouTube, MySpace, FaceBook, etc from school or work? Most people end up trying out the million or so proxy servers out there, but those are usually dead ends. Also, those proxy servers are very slow and it can take a year for a single web page to load sometimes! There’s luckily an easier way to access blocked websites that doesn’t rely on proxy servers!
JAP is a free open-source software tool that can be used to browse the web anonymously and unobservably. Whenever you browse the Internet, your IP uniquely identifies your computer and your location to the requesting servers, thereby reducing your privacy. JAP uses a single static IP address for many JAP users, thereby making it impossible for the visited website or any sniffer to determine which user visited.

The extra benefit that we can also get out of using JAP other than anonymous browsing is the fact that it can be used to access blocked web sites! That’s because all requests are first passed to JAP servers, then the requested sites are retrieved from their servers. Basically, for the local servers that control your access, it looks as if you’re always requesting something from the JAP web site, not FaceBook or MySpace, etc.
Here’s how to setup JAP: first download the JAP app from the link above. Install it and make sure it’s up and running. Then all you have to do is change some of the settings in Internet Explorer or Firefox. You have to change the LAN Settings so that the Default Gateway is 127.0.0.1 and the port is 4001.
In IE, click on Tools, then Internet Options, and click on the Connections tab.
lan settngs
If you’re connecting to the Internet using a dial-up, modem, or ISDN connection, choose your connection and then click on the Settings button at the top. If you’re connected permanently using a LAN, Cable or DSL connection, click on the Settings button under Local Area Network (LAN) settings heading.
browse anonymously
Check the Proxy Server box and type in the IP address and port number shown above.
For Firefox, you click on Tools, then Options, and then click on the Advanced tab. Under Connection, click on Settings.
jap ports
Click on Manual Proxy Configuration and enter in the same information. Check the box to use this proxy for all protocols. You can also download a cool plugin in Firefox called SwitchProxy that will allow you to quickly switch between JAP and normal browsing.
You should now be able to access blocked web sites while JAP is running. However, if you are at the office or at school and the only ports that are open are port 80, and 443, then JAP won’t work without a little more tweaking.
  • In JAP under “Config/InfoService“, change the port from 6543 to 80
  • Go to the “Config/Anonymity” page. Click on the “Fetch” button and choose the “Dresden-Dresden” cascade from the drop down menu.
  • Select the “Manual Configuration” radio button and change the Anon-Port from 6544 to 443
Now try to activate the anonymous web access. If you’re able to connect, you’ll now be able to browse web sites using the normal web access ports so even if your company or school blocks all other ports, you’ll still be able to access JAP.
Also, if your company forces you to access the web through a proxy server, then you’ll need to configure that in JAP. You can see if you have to go through a proxy server by checking out the values in the above LAN settings section. If it’s greyed out with something already in there when you tried to change it to 127.0.0.1, that means you’re going through a proxy server.
In that case, in JAP you need to do the following:
  • Activate the checkbox under “Config/Proxy-Firewall” and enter the address of the required proxy. Some proxies require a user authorization. If this is the case, activate the appropriate checkbox and enter the User ID. (First try it without authorization and only do this step if it doesn’t work.)
  • Under “Config/InfoService“, change the port number from 6543 to “80″.
  • Go to the “Config/Anonymity” page. Click on the “Fetch” button and choose the “Dresden-Dresden” cascade from the drop down menu.
You should now be able to connect to the JAP service and access any web site that you like! If that was too technical or something was not explained clearly, please post a comment and I will try to help as much as possible! Enjoy!

How to fix USB device not recognized in Windows

Are you getting a “USB device not recognized” error whenever you plug in a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!
However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!
usb device not recognized
So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That didn’t work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn’t work!
I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!
You may also see in Device Manager that the device shows up as an “Unknown Device”.
unknown usb device
So how did I finally fix the problem? Well, apparently it’s a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.
Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that’s it! Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.
First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be “rebooted” also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!
So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.
Hope this helps someone fix that pesky “USB device not recognized” Windows error!

Gmail Backup – Backing Up Gmail Data to Your Computer


gmail-keyboard-shortcuts Gmail keyboard shortcuts are a great way to increase your computing performance. These small combinations of keystrokes within Gmail can be a real productivity booster and help you avoid having to move your hand from keyboard to mouse as frequently. Our previous posts on keyboard shortcuts have included Firefox shortcuts, Internet Explorer shortcuts, Google Chrome Shortcuts and Windows shortcuts. Here are 45 timesaving Gmail keyboard shortcuts to help increase your efficiency when using the Google mail environment.

Gmail Keyboard Shortcuts – Some Differences

Gmail shortcuts are somewhat different than browser keyboard shortcuts for two main reasons:
  1. Limits on Keystroke Choices: when using Gmail keyboard shortcuts you are working within a web browser so Gmail cannot duplicate any of the standard shortcut key combinations used by Firefox, Internet Explorer, Chrome, Safari or Opera web browsers;
  2. Functions Vary by Location: Gmail shortcut functionality is based on your location within Gmail. Some shortcuts function only when reading a message or conversation, some work only when viewing conversation lists such as Inbox or All Mail, or viewing Contacts or Tasks.
Activating Gmail’s Keyboard Shortcuts
Before these shortcuts can be used you have to make sure that the Keyboard Shortcuts Setting for Gmail is set to “on” in Gmail Settings as shown here:

Tips to Improve your android battery life

Tips to improve battery life

  • Turn off unnecessary Wireless : The number of wireless operating devices that are turned on affects your battery life. This includes

    • WiFi
    • BlueTooth
    • GPS (Global Position System)
    • NFC (Near Field Communications)
    • 3G/Data connection
    • 2G voice communication.

    So the more devices that are turned on the more battery is consumed. Typically you would not need to use BlueTooth and GPS so you can turn it off when not used. Typically the wireless settings are under Settings > Wireless and Networks, as shown below:

    Android turn off Wireless

    Similarly with GPS which is under Settings > Location. GPS takes up a lot of battery when used. If you are not using 3G, you can disable 3G altogether by enabling the "Use only 2G Networks" setting in Mobile networks settings. A good application that ships by default in android is the power control application widget which can be put on the home screen to put shortcuts of these settings on your home screen. A slightly advanced version you can use is available as Widgetsoid in which you can configure your shortcuts. Here is my widgetsoid widget on my home screen that has shortcuts to most of the battery saving techniques discussed here:

    Android widgetsoid widget
  • Applications and Services :

    • The more applications you run, the more your CPU is used. Typically playing games result in draining of the battery. So if you want to save a battery life for that important call, you better not play that game. You can use a task killer to see and kill the applications. Applications such as "Task Killer", "Advanced Task Killer" etc can help you with this.

    • The similar is with services. There are many services that run on your android phone that does many tasks. You can stop some of the non essential services to save your battery life. You can stop running services by going into Applications > Running Services > Tap on the Service > Tap Stop

      see running services in android

    • You can also turn off background data and account sync to save battery life.

  • Wallpaper and Display :

    • Display brightness can determine the usage of your battery, the more the brightness the more the battery usage. So to extend the life we should use as minimum as possible. But since usability is a big concern, putting the display in automatic brightness is the best as it automatically increases and reduces screen brightness according to ambient light. You can find the settings > Display > Brightness.
    • While you are at it you can also reduce the Screen timeout to a lower value so that your screen is turned off when not in use which can save you lots of juice.

    • Putting a live wallpaper can also eat more of your battery life so if you want to improve battery life consider using a static wallpaper. It would also help to choose a dark wallpaper with lots of black as it requires less energy to display a black dot than a white dot. So using a dark wallpaper definitely helps. See my wallpaper at nexus s wallpaper for a dark wallpaper.

  • Tones and sounds :

    • You can reduce the volume or turn off unnecessary sounds like Screen lock sounds.
    • You can also turn off Haptic Feedback to save battery.

On the move battery drains faster

This one is applicable to any mobile phone not just android, when you are on the move the cell networks and antennas keep changing this causes significant radio traffic and hence drains more battery. Moreover more battery is used to communicate to weak signals from various towers. You can turn off all the wireless if you are absolutely positively sure of not expecting any calls (This is true when doing overnight journeys and half the journey you may not have a signal) by turning on the Airplane mode. But you wont get any calls or messages making your phone useless, but battery is saved so that you can use it when you arrive at your destination.
