How To Block In-App Ads

How To Block In-App Ads

  20:20    BackBenchers World

Guys! Suppose you are playing any game or using any other application while internet connectivity then a lot of ads in footer or header area are shown. This is really annoying and wastes the bandwidth up to some extent.

So, the next question is who to remove those ads. There are basically two methods. The first one is either you buy the app which you never gonna do anyway or you block the ads by blocking proxy which let the apps to connect to the ads network.

Here is demonstrated NoRoot Firewall app for the android platform. There is another app named Droidwall. What makes the difference? NoRoot as the name signifies also works with full functionality on non-routed phones where as Droidwall requires root privileges.

Home Screen is shown firstly when you start the app. This screen has START/STOP control.

Now there are various others tabs which include PENDING ACCESS, APPS, GLOBAL FILTERS, and ACCESS LOGS. Each tab has its own functionality and is/are described below shortly.

PENDING ACCESS

It shows all the apps which ping the network. It will ask you to ALLOW or DENY access. If it is a system app then allow the access else tap deny. But wait, if you deny the whole services of that app will be blocked. You only want to block the ads, not the complete internet access. Now what to do? Tap on that particular app and you will see all the proxies which want internet access. If a particular proxy is pinging the ads then block it by double cross sign else allow it.

APPS

It shows the list of all the apps which are installed on your devices either it is a system app or post installed ones. If you tap on any particular app you will see Add Custom Filter. This option allows you to allow/deny access to the internet for proxies.

GLOBAL FILTERS

This is most amazing. Here if you add a proxy to Pre-filter then that proxy will be blocked for all apps instead you need to add custom filters for all apps for that proxy.

ACCESS LOGS

In this tab, you can monitor all the proxies which one is having access allowed and denied and pending access as well.

Note:

1. The more you spend time with something the more you will know about that thing..

2. Your Wi-Fi hotspot might show a limited connection when this firewall is enabled.

This technique is called as Stenography. It involves hiding data behind images so that only the intended recipients can read the message being sent. I will show you how to hide files inside a picture file. They are almost undetectable, and can be made very hard to get. You can not only hide files in pictures, but music files, videos, and just about anything else.

There are so many S-tools available to hide data behind images. But here you don't need any tool for this. You will need these things:
1) A picture to hide stuff in
2) Files to be hidden
3) A file compression software (I’m using Winrar)
4) Command Prompt

So here we go.

Step 1: Add the data files to a single .rar file and place a image file in the directory containing the rar file.

Step 2: Open Black Box (Command Prompt). [Press windows key + r. Type cmd and press enter. It will open black box.]

Step 3: Select the Disk Drive by writing drive_name: and peress enter. E.g. desktop: or c: or d:. 

Step 4: Now type the command copy /b <Image.jpeg> + <File.rar> <New_name.jpeg>. And press enter and its done.

Note: Don't include < > while running the command. These sign(s) are only enclosing a file_name with it's extension.

Now you would like to know how to excess that hidden file.

What you have to do is only to open that image file with winrar. It will open the rar file hidden behind image file.

For that:

1. Right click on image file containing the hidden rar file.

2. Goto Open with and chose Winrar. And the hidden rar file is opened.

Turn Your WiFi Into HiFi

Turn Your WiFi Into HiFi

  09:12    BackBenchers World

Have the slow Wi-Fi speed troubled you? You want high speed, but you are not getting any solution for this? Now it's time to get rid of this problem. Here are discussed some tips for the same.

Setup the router in centre

For fast speed it's very necessary to setup router at proper place. You should install router at centre or nearby to centre of your home so that signal could reach at each any every corner properly. If there are various floors in your home or office, then it would be better to install router at top floor. Electronic devices produce interference in Wi-Fi signal, so always keep in mind that devices like microwave, TV, refrigerator, cordless phones, halogen lamps etc. are to be kept at least 10 feet away from router.

Boost your Wi-Fi with booster antenna

Generally router has one or two antenna(s), but due to this signal doesn't reach to each any every corner. So, in this situation, it would be apt to install booster antenna for strengthening the signal. It will widen Wi-Fi range and increase speed also.

Not to share Wi-Fi network name (SSID)

Do not share your Wi-Fi Network Name with any of neighbrour or anybody else. For hiding Wi-Fi network name, turn off Service Set Identifier under Broadcasting Option. It would be better if you add password to your Wi-Fi Network Name.

Remove Interference

Interference of one Wi-Fi signal with another Wi-Fi signal causes weakening of signal. To get rid of this problem, Wi-Fi Stumbler or Wi-Fi Analyzer could be used. This will prevent interference of other's Wi-Fi signal with your Wi-Fi signal and in turns it will result in increased Wi-Fi speed along with strengthening the signal.

Latest technology always rocks

The best option for high speed Wi-Fi is to use latest technology. Means always use up-to-date hardware. Wireless 'a', 'b' and 'g' has become old and it works slowly. Wireless 'n' is the latest version and it gives very fast speed. Using wireless n card with your laptop or PC along with wireless n router will give you best possible results in terms of speed.
