Truecaller is an “Awesome” app I must say. Most of my friends use it, but not me. There are a couple of flags and I will show you why I don’t have it installed.

Description

Truecaller helps identify unknown calls with Caller ID, blocks unwanted spam, scam calls all over the world reported by our users.(You)

* See who is calling if you donā€™t have their number in your phonebook
* Block unwanted calls from spam callers and telemarketers
* Search for any number in the world to see who it belongs to
* You can now copy a number anywhere (e.g. website or apps) and Truecaller will notify you who it belongs to
* Get in touch with people via name search (Premium feature)
* Tweet and Follow a person on Twitter directly from Truecaller
* Yelp! integration for faster business search results
* + more features to make your phone smarter

Whenever an unknown number calls you, if your GPRS/wifi is active, this app shows you the name of that caller. You can also go to their site and search for a number. You need to login with Facebook, Windows Live Yahoo or Google Plus. Cool features, yes? Well ladies and gentlemen, sorry to burst your bubble but you actually help Truecaller help you.

Red Flags

1. How Do They Get Their Info?

Don’t just use apps just because you are told they are awesome. Question everything.

Truecaller NEVER uploads your phonebook to make it searchable or public.Ā 3G or WIFI is required for Truecaller Caller ID to work. Operator charges may apply.” That is what they tell you.

Truecaller Never UPLOADS… Let’s pause for a second or two.. Okay let it sink in. What do they mean by that. I mean, this is so vague but if they were honest, they would not be in business now.

So how do they get a users name? e.g When a strange number 0724 *** *** calls, you will be informed that “Julius Caesar” is calling.

This is how I ‘think’ they do it.

  1. I saveĀ 0724 *** *** asĀ “Julius Caesar”.
  2. Once I install Truecaller, ALL my contacts are synced to TrueCallers database.
  3. You install TrueCaller and process 2 is repeated.
  4. “Julius Caesar” calls you but you don’t know if the aliens are trying to make contact so Truecaller verifies that by looking forĀ 0724 *** *** in their database.
  5. You are in luck, it’s not the aliens butĀ “Julius Caesar” and thanks to “me” Truecaller tells you who it is.

You have to hand it to the guys behind Truecaller. This is what they say on the Description section.

2.Ā Why so many permissions?

Let’s begin

The Permission Nest:

Now this ladies and gentlemen, makes my jaw drop. Look at all those permissions..

TrueCallerPermissions

Ā A. Photos/Media/Files:

Some of you will argue that this permission is required to get the contact info. I tend to disagree. Truecaller is meant to help you find out who is calling, or at least that is what they say. So I don’t know why they need to access your Photos, Videos Audio and SD card.

B. Location:

Truecaller helps you find the location of the caller. What if Truecaller gets your location? Think of the information they will have on you. Person X likes hanging out at Restaurant Y for 2 hours every Saturday……… *Evil Laugh*

TrueCaller_Location_Permission

C. Call Log

Truecaller gets access to your call log. *Clears throat*. Ā Person X always calls number 0724 *** *** at 8:00 PM of 20 mins everyday. ……

TrueCaller_CallLog

D. Bluetooth Connection Information

Why the hell do they need Bluetooth permission? This permission allows the App (Truecaller) to control Bluetooth, including broadcasting to or getting information about nearby Bluetooth devices.

Conclusion

Don’t get me wrong. Truecaller is an awesome application BUT it has a lot happening Ā under the hood. Truecaller exists because you and 1,000,000 + 1 users clicked install.

Before you click install, go through the permissions. If you are not sure Google or ask. Once you click install, you accept the terms and conditions.

Cannot find any VM in Java_Home – Mac

This is going to be a short one. so let’s get to it.

Today was one of those days you go past page 5 searching for an answer in Google. Hopefully you will not have to go through the same process I did to get a fix.

I have been working with daemons and i hit a snag. The VM/JVM not found snag.

I got the following error when running the daemon: “Cannot find any VM in Java Home /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home
Cannot locate JVM library file”

After scrolling through the web I finally got a fix.

Solution:

Open terminal and type the following commands:

NB:Ā ReplaceĀ jdk1.7.0_71.jdk with your jdk version.

$ cd /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents
$ sudo ln -s Home/jre/lib Libraries
$ cd Libraries
$ sudo ln -s server/libjvm.dylib libserver.dylib

That’s it. Problem solved šŸ™‚

Let me get back to what I love doing, saving the world.
