Should you use Login with Google or Login with FaceBook in other sites?

Many sites are offering the facility to Login with Google or FaceBook (using OAuth or Open Authentication). This is easier for us so that we do not need to create and remember passwords for these sites. 

Just a thought came to my mind that at a later time (not sure if this is the case now) Google or FaceBook will update their privacy policy such that they can use the information to login to the third party sites and index our data! Google is the biggest online advertiser, so they will use this data for sending adverts.

It may be okay to use this facility for kind of news sites, but for sites that have sensitive data, it is advisable to use a username and password combination.

Moreover, when using this facility to gain access to third party sites, we will be shown the list of permissions that we are granting to the third party sites. If we are giving offline-access, the third party site can access your Google/FaceBook account at any time without your intervention and will be able to post in Google+/FaceBook. So carefully understand and give permissions to your account to the third party sites.

Note: A new app by Intel and McAfee named TrueKey is now available which stores your credentials for different sites. The app then auto-fills the information on the login page. Worth trying.

Privacy in Internet - Avoid flash cookies

Due to some of the recent developments in the area, the browsers have a Do Not Track functionality which does not let the sites to identify a browser and ultimately you and your browsing habits. But the Ad providers are using Flash cookies which need to be blocked separately.
The method here is to block all flash content in FireFox and let the user choose which flash content to run. This has another advantage that unnecessary flash Ads will also not be played and thus saving bandwidth. An 'Activate Adobe Flash' message will be shown over blocked content. So, if you want to play a flash, click on the link and view it.
  1. Open FireFox and press ctrl + shift + A to open Add-ons Manager.
  2. Find Shockwave flash in the list.
  3. Change the button to the right end to 'Ask to Activate'.

Now if a site try to save flash cookie, you will see a notification below the address bar. You can now see how many of the sites you regularly visit are tracking you.

NOTE: This method is also not sufficient to avoid browser finger printing used by Ad providers. I will blog later on how to avoid browser fingerprinting.

Best way to get portable WiFi Internet in India for light or medium users

I think this post will benefit users who are thinking to get Internet in their mobile devices.

If you are a light internet user and have multiple devices, one way you can choose is to tether your connection with your devices. This will drain battery on your device. Otherwise you will need to buy Internet packs on all the devices which will not be a cost-effective method.

My plan is to have a single connection that can be shared with all the devices so that you need only one data plan and the devices will be connected with WiFi means less battery drain. The initial investment is a bit high though ;-)

The devices you need are:
  1. GSM WiFi dongle that usually supports 5 - 10 devices to be connected at once. (Sample)
  2. USB power-bank. (Sample)
  3. BSNL GSM connection with Internet. I chose BSNL as this is the cheapest with Rs.155 for 1GB data as of now and will support both 3G and 2G on this pack.
Setup is simple, slide in the SIM to the WiFi dongle and connect to a computer. You can add the WiFi security information (as you do while Tethering in mobile) in the page that automatically opens. You can select 3G only for faster Internet.
After this one time process, you can use the WiFi dongle in the power-bank and you can connect your devices. A 2100 mAh power bank can power the WiFi dongle for almost 12 hours.

Not just home, you can use this setup anywhere you want and the battery drain on your device will be less compared to using data in the device's connection. I believe with BSNL you can go anywhere in India and continue to use the Internet.

Optimal settings for an iPhone to save battery (my experience)

There are lot of articles telling you to turn off many features in an iPhone to save battery and this is not one of those. I have been changing settings and get a best battery life for my iPhone 5c and with the following settings I am easily getting a 30 hour usage on a single charge. You can also try this.

UPDATE: I have written another post on how to setup cheap portable wifi. Check here.
  1. Switch off the battery percentage indicator (Settings -> General -> Usage -> Battery Percentage) and do not check the phone constantly to see if you got a notification.
  2. Use a louder ring tone (Settings -> Sounds) so that you are notified and use vibration.
  3. Use Auto-Brightness (Settings -> Display & Brightness) and set the level to the minimum that is comfortable to you.
  4. Use smaller text Text Size (Settings -> Display & Brightness) suitable for you. This will help you to read faster.
  5. Group the less-commonly used icons in folders so that you can access the productive apps faster.
  6. Facebook is one of the battery hungry app. Uninstall it if you have, there are other important things you should care about.
  7. Check that you have given Location Services only for required apps (Settings -> Privacy -> Location Services). Enable the Location Services only for apps that is useful to you. To the bottom of list there is a System Services item. Click on that and enable the Location Service only for Find My iPhone only.
  8. Use Cellular Data in utmost necessity. At places of bad coverage, it drains the battery a lot.
  9. Make sure to switch off WiFi and Bluetooth when not in use and lock the display orientation (swipe up from bottom in the home screen and enable the last icon on the top row)
  10. Enable Push notification for mails (Settings -> Mail, Contact, Calendars -> Fetch New Data) only when you require. Otherwise set the interval to Hourly to get the maximum battery.
  11. Switch off sound and notification center display for unnecessary apps. Go to Settings -> Notifications and disable notification. You will still see the badge with the number of notification above icon. You can also opt to completely disallow notifications for apps here.
  12. Do NOT close the commonly used apps. This will drain battery.
  13. Use Do Not Disturb (Settings -> Do Not Disturb) suitably.
  14. An advice from Apple: Change the phone to Airplane Mode (Settings -> Airplane Mode) in area of low/nil coverage to save battery.
You may try changing these settings as you like and see how it works for you.

How is the price of some of products are kept constant for few years?

There is a joke about a person who is not concerned about the price of petrol. When asked he said "I don't care whether the price of petrol increase or decrease, I will only fill for Rs.100/-".
Do you know most of us have done this for years, may not be petrol, but for most FMCG goods?

Yes, if you notice the weight of the toothpaste that you have been using for years, you can see that it has been reduced while the price was maintained the same.

As we are only checking the price usually, we do not notice a small difference in the weight.
These are happening for lot of products.

Try to keep a watch on the price and weight from now on and see the changes.

ColdFusion CFHTTP analogous to CURL

* This is a continuously updated post on the corresponding CFHTTP syntax for CURL. If you need help, send me a message and I will try to help.

I have been trying to integrate different APIs with ColdFusion/Railo recently and the difficult part is of course to understand the way the API is expecting data. Mostly they 3rd party will provide library or code for PHP and .NET, but not for ColdFusion. In some cases they provide the CURL syntax. I thought I will scribble my findings here so that it is useful for someone to write CFHTTP by seeing the CURL syntax.


File Upload 
e.g.: 
  1. to post a file to the folder /upload to the server. The URL is http://app.prasanthkumars.com/upload
  2. the API uses Basic Authorization
  3. File name is test.png

CURL
curl -f file=@test.png "http://username:password@app.prasanthkumars.com/upload"

CFHTTP
<cfset credentials = tobase64("#username#:#password#")>

<cfhttp method="POST" url="http://app.prasanthkumars.com/upload" result="upload_result">
     <cfhttpparam type="header" name="Authorization" value="Basic #credentials#"/>
     <cfhttpparam file="c:\test.png" type="file" name="file" mimetype="image/png">
</cfhttp>
