An Android Math Game

Having good math skills are imperative for any one of any age. Almost all of us struggle with performing simple arithmetic tasks in our day to day life. Like adding the cost of each item that we purchased at the grocery store, or quickly adding up the quantity of paint we need to do our next paint job. You do not need to be a math expert to succeed in overcoming these tasks, but you need have your mental math skills polished if you need to calculate stuff without having to depend on a calculator. This is where Android Math Games comes in handy. They allow us to practice math skills where ever we are.

What the Math!?




I am going to talk about one app that I like in particular. Its called What the math. It features an impressive collection of math questions that you need to answer before the timer goes out. So far I encountered four types of math questions and the comparison questions are the ones that I like the most. Those questions require quite a lot of attention and almost all the time I run out of time.




The calculation in the picture above depicts what I have been explaining. After you solve the left hand side of the problem you are left with -17 and it is in fact greater than -22. Sometimes when I am in panic mode, I tend to choose the wrong answer and am tempted to try again, which of course I would have to start from the beginning.

Note that the picture above is from the developers play store page. In the game, such questions do not appear as soon as answering 2 correct questions. Usually they appear after around 20.

The developer mentions that the app is compatible with android versions 4.2 and above. Be sure to give this math game a try, right away!!!

Note 2 has been my primary phone since 2012

My Note 2 Phone


Hello guys, i have been using my note 2 since december 2012. During that time the note 2 was the phone to have and everyone that i came across was facinated and talking about it. It had the best specs and features among the phones that were at sale and soon became the phone of choice for many, including myself. Among the tons of new features and capabilities that it boasted, the amount of processing cores and RAM were the key performance metrics that caught my attention. It came with 4 processing cores and 2 giga bytes of RAM. Furthermore, the 5.5 inch Super AMOLED capacitive touchscreen with 16 million colors gave such a overwhelming viewing experiene that you suddenly lose the sense of time. Screen resolution of 720 by 1280 was pretty darn good but not that great in today's tems. Until then, i was using a Sony Ericsson Neo V and going from that to a Note 2 was such a leap in specs that it was so exhilarating.

Shopping for phone cases


Next i went on to shop for cases and due to obvious reasons it was difficult to find a decent case for it since it was so new to the market. I searched the internet and came across an company called otterbox that sold sturdy cases for my phone. Youtube videos that showcased drop tests where they drop the phone from roof tops and still manage to withstand without breaking apart really blew me away. The original otterbox defender case that i used did not manage to survive beyond 3 years. The outer cover began to sag and the clips that held the inside cover together started to lose strength so i decided to purchase a new otterbox case. Luckily there were Note 2 otterbox defender cases for sale for reasonalbly good prices on ebay so i purchased one and i am quite happy with it.

Phone speed


My phone received a few original updates from Samsung over the years and i am currenly running Android 4.4.2. Although OS updates and individual app updates have made my phone a little bit slower i do not consider moving to a new phone anytime soon.

Execution failed for task ':app:transformClassesWithDexForDebug'.

Hello everyone. I just created a new android tabbed project and i ran grade build. I expected it to build successfully howeever i was confronted with the following error
FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:transformClassesWithDexForDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'D:\Dev\Java\jdk1.8.0_65\bin\java.exe'' finished with non-zero exit value 1 * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Philips Over-Ear Sound Isolating Bluetooth Headphones Review

Search for a bluetooth headphone


Hello folks. I was searching for a pair of headphones recently and i went online and read reviews for some. I get really excited when i go shopping for something and buying a new headphone was nothing different. After browsing through numerous headphones and reading a plethora of reviews i was still not sure what i was suppose to buy. One aspect that i wanted was the versatility and therefore i turned my attention towards blue-tooth headphones.
 

The Philips SHB7150FB


Among the Bluetooth headphones, the Philips SHB7150FB caught my eye. I was a over the ear headphone with Bluetooth capability. Also it had noise cancelling facility too. Furthermore it came with NFC pairing feature too that makes pairing less of a hassle in some cases. Without too much thinking i went ahead and purchased it. I still do not regret buying it as it suits my wants and needs really well. There is not much to complain about the sound too. In fact it sounded better to me than its rivals. I am able to stream music to it through my Samsung Galaxy note 2 mobile phone and my windows computer too. However listening to music over Bluetooth with my windows 8.1 computer is not aesthetically pleasing to the ear as it connects to it in the headset mode. And as we all know headsets don't sound good at all and the windows 8.1 sound over Bluetooth connection doesn't make a difference. I attempted to make it connect like a regular headphone but still couldn't.
So now lets discuss a few important specs. The manufacturer claims it to be able to reproduce sounds from a very low 10 Hz to a very high 22000 Hz. However i doubt anyone could actually claim to hear such low and such high frequencies. The diameter of the voice coil is 40mm and a Neodymium provides the magnetism. I supports A2DP, AVRCP, HFP, HSP bluetooth profiles and therefore should be compatible with a wide range of Bluetooth music devices. The built in LI-Polymer battery provides a long 9 hours of listening and it suits almost everyone's need.
Overall i am happy with regard to this headphone and i can certainly recommend it to anyone who requires a decent headphone for a reasonable price.

Linux tricks

Hello guys,. Welcome to my blog post on linux tricks. I am a long time windows fan and still use windows on my primary home computer. However i use a mac at work because i do IOS development. Nevertheless i use linux every now and then.

Here are a list of useful linux commands to learn

reload .bashrc file without having to reboot linux

source .bashrc

How to share a folder on linux using samba and connect to it through windows

open /etc/samba/smb.config

and add the following text

[share]
    comment = Your Comment
    path = /srv/samba/share
    browsable = yes
    guest ok = yes
    read only = no
    create mask = 0755

Save the file and restart samba server. (Command :- smbd stop and then smbd start ) Now enter ifconfig command to determine the ip address of linux. Now since you know the ip address you can map network drive under windows.
