The Best Way To Charge Our Mobile Phones According to Science
We all know that our smartphone batteries are bad as they hardly last a day. But it is partially our fault because we are charging them the wrong way whole time.

Most of us (including me) have a belief that charging our smartphones in small bursts will result in some long-term damage to their batteries and that it is better to charge the mobile when they are below 5%.

But we just couldn’t be more wrong.

As a matter of fact a site from battery company Cadex named Battery University shows how the lithium-ion batteries in our smartphones are very sensitive to their own versions of ‘stress’. And, like us humans, extended stress could damage our smartphone battery’s lifespan.

If you want to keep your mobile battery in top condition and get a full day of charge without worrying, then you have to change a few things.

///

Do not keep it plugged in when it’s fully charged

According to the Battery University, leaving your phone plugged in when it is fully charged just like we might overnight, is very bad for the battery in long run.

Once your phone reached 100 percent charge, it will get ‘trickle charges’ to keep itself at 100 percent while it is plugged in. This keeps the battery in a very high-stress and high-tension state, this wears down the chemistry within it.
The Battery University gives a bunch of scientific detail and explanation to this, but it sums it up nicely: “When fully charged remove the battery” from the charging device. “This is just like relaxing the muscles after exercise.” You would be in a pretty miserable state if you worked out nonstop for hours and hours.

Plug in your phone whenever you can

As it turns out that the batteries in our smartphones are much better if we charge them occasionally throughout the day instead of just plugging them in for a large charging session when they are empty.

Charging our phone when it loses a 10 percent of charge would be the best case scenario, according to the Battery University. So, it is fine to plug in and unplug multiple times a day.

This keeps your smartphone battery to perform optimally for longer time, and it also keeps it topped up throughout the day.

to get started with AI(Artificial Intelligence)
Posted by Aashiq Hussain kuchay
Artificial Intelligence (AI) is the study of computer science focusing on developing software or machines that exhibit human intelligence.


A lot of people think that AI is just a sci-fi concept that’s being used in movies like Star Wars, Terminator or Lucy, but there is a lot more to it. AI is a very broad topic ranging from a simple calculator to self-drive technology to something that might change the future.

Primary Goals and Applications of AI
The primary goals of AI include deduction and reasoning, knowledge representation, planning, natural language processing (NLP), learning, perception and the ability to manipulate and move objects. Long-term goals of AI research includes achieving Creativity, Social Intelligence, and General (Human Level) Intelligence.

AI has heavily influenced different sectors, that we may not recognize. Ray Kurzweil says “Many thousands of AI applications are deeply embedded in the infrastructure of every industry”. John McCarthy, one of the founders of AI, once said that “as soon as it works, no one calls it AI anymore.”

While, there are various different forms of AI as it’s a broad concept, we can divide it into the following three categories based on AI’s capabilities –

Weak AI – Also referred as Narrow AI, a weak AI focuses on one narrow task. There is no self-awareness, genuine intelligence in case of a weak AI.

Siri is a good example of a weak AI combining several weak AI techniques to function. It can do a lot of things for the user, but fails when asked question outside the limits of application.

Strong AI – Also referred as General AI, or Human-Level AI, it’s a computer that is as smart as a human brain. This sort of AI will be able to perform all tasks that a human could do. There is a lot of research going in this field, but we still have to conquer it.

Artificial Superintelligence – Nick Bostrom, leading AI thinker, defines it as “an intellect that is much smarter than the best human brains in practically every field, including scientific creativity, general wisdom and social skills.”

Artificial Superintelligence is the reason for why many prominent scientists and technologists including Stephen Hawking and Elon Musk have raised concerns regarding the possibility of human extinction.

How to Get Started?
The first thing that you need to do is learn a programming language. Though there are a lot of languages that you can start with, Python is the preferred choice of many to start with because of libraries better suited for Machine Learning.

Here are some good resources for Python –
https://www.codecademy.com/learn/python
http://learnpythonthehardway.org/
https://www.coursera.org/specializations/python
http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/

Introduction to Bots
A BOT is the most basic example of a weak AI that can do automated tasks on your behalf. Chat bots were one of the first automated programs to be called as ‘bots’.

Web crawlers used by Search Engines like Google are a perfect example of sophisticated and advanced BOT.

You are advised to learn the following before you start programming bot in order to make your lives easier –

xpath – This will help you to inspect and target HTML and build your bot from what you see there. You can learn more about xpath here –http://www.w3schools.com/xpath/xpath_syntax.asp


regex – regex will help you to process the data you feed your bot by cleaning up or targeting (or both) the parts that matter to your logic. You can learn and practice regex here – http://regexr.com/

REST – This is really important as you will eventually work with APIs. You can use requests to do this for its simplicity. Learn more about it here –http://docs.python-requests.org/en/latest/index.html

How to Build Your First Bot?
You can start learning how to create bots in Python through the following two tutorials in the simplest way –

http://code.tutsplus.com/tutorials/how-to-build-a-python-bot-that-can-play-web-games–active-11117

You can also start by using APIs and tools that offer the ability to build end-user application. This helps you by actually building something without worrying too much about the theory at first. Some of the APIs that you can use for the same are –
https://cloud.google.com/prediction/docs
http://www.diffbot.com/products/
http://mallet.cs.umass.edu/
http://scrapy.org/
http://products.wolframalpha.com/api/

We are also listing a few BOT problems for you to practice and try out before you take the ultimate challenge –

https://www.hackerearth.com/battle-of-bots-2/multiplayer/dots-and-boxes/
https://www.hackerearth.com/battle-of-bots/multiplayer/isola/

What now?
Once you have a thorough understanding of your preferred programming language and enough practice with the basics, you should start to learn more about Machine Learning. In Python start learning Scikit-learn, NLTK, SciPy, PyBrain, and numpy libraries which will be useful while coding Machine Learning algorithms.

It is also very important to familiarize yourself with Advanced Math and Stats as it will help you a lot in writing ML algorithms.

Some Books for AI –

https://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Main
http://psych.colorado.edu/~oreilly/comp_ex_cog_neuro.html

We also encourage you to participate in various AI & BOT Programming Contest at different places on the Internet –
https://www.hackerearth.com/
https://www.kaggle.com/
http://www.codingame.com/
https://en.wikipedia.org/wiki/RoboCup

HOW TO ENABLE COPY PASTE IN CMD – WINDOWS
By AHK Technicals


By Default Windows do not allow users to Copy text and Paste it in Command prompt Or Copy text from Command prompt and paste it elsewhere. But there is an option in CMD itself to enable Copy & Paste Text in Windows Command Prompt.

Today in this tutorial we will learn how to Enable Copying and Pasting Texts in Windows Command prompt. One of the main advantage of this will be that you can copy any command that you find on the internet or from any word/excel file and paste it directly in CMD and execute that command just like that.


HOW TO ENABLE COPY PASTE IN CMD

Step 1: Open CMD, Just type CMD in search or Press Win + X key to select Command Prompt.

Step 2: Right Click on the Title of the CMD window and Select Properties just like its shown in the below Picture
Enable Copy paste in CMD

Step 3: You will see a Pop up Window coming up, Now on the Right hand side, Under Edit Options, Just Check Quick Edit Mode and click OK

Step 4: Everything is Done, Now just Copy any Text from Here or Anywhere else Using CTRL + C keys and just Right click using your mouse on CMD. You will see that the text is been pasted automatically in CMD. Please Understand that Using CTRL + C to Copy text is Important.

Likewise if you wish to Copy Text from CMD to paste elsewhere then Just Select the Text in CMD and Again just Right Click with the mouse. Your Text is Copied and ready to Paste it in any Document you want.

This Doesn’t Limit you to just Text you can even copy File or Folder path and paste it in CMD. Everything that you have to type manually can be copied from somewhere and pasted directly to CMD with this small Tweak

So this was just a small Tip I wanted to Share with my Readers so that you don’t have to Type any long Command in CMD which if typed incorrectly can cause errors. I hope this will help some Of you.

HOW TO CREATE RESTORE POINT IN WINDOWS 10
By AHK Technicals


Having your PC compromised in any way can be damaging and can cause a lot of stress for you. Simple tasks such as installing a new app, driver, or update can create issues with your computer, and you may want to undo the changes you made to revert your PC back to normal. This is where creating a restore point in Windows 10 can be beneficial for you.

Restore Point allows you to essentially save a ‘snapshot’ of your computer at a given moment which is then stored as a restore point. If your computer Somehow starts working awkwardly or becomes laggy, you can then revert to this restore point that you saved and your PC will go back to how it was at that time.



IMPORTANCE OF CREATING RESTORE POINT IN WINDOWS 10 PC

Most of us had encountered a problem here or there with Windows before and wished that we could undo changes and bring back our PC to how it was before. By creating a restore point on a Windows PC, you can effectively bring back your computer to a previously saved state if you think that its current state is compromised.


So you are basically going back in time to how things once were instead of your PC operating in its current capacity that you’re unhappy with. It should be noted that if you have installed any programs after a restore point has been created, that once a restore is performed those programs will not be there anymore.



HOW TO CREATE A RESTORE POINT IN WINDOWS 10



Step 1: Open up Control Panel on your PC. You can access it by either using your computers built-in search function, through the Quick Access Menu, or by using Cortana.

Step 2: Open up the System and Security section and then click on System. Now from the left pane click on System Protection.


Make sure that the Windows Drive (usually C) has Protection set to On by selecting the drive and clicking on Configure.

Step 3: Click on the Create button to create a system restore point. You can write a description so that you can remember in future why this restore point is important to you.



HOW TO USE A RESTORE POINT IN WINDOWS 10



Step 1: Open up Control Panel on your PC as mentioned above.

Step 2: Go into the System and Security section then open up System Protection.

Step 3: Click on System Restore, and you will see a list of available restore points to choose from.

Step 4: Click on Next and then Finished to begin a system restore.

That is it Folks, you just learned how to Create a restore point on your PC. If you do not have restore point created already, then you should go ahead and Create one just now. You never know when a program or system files can make your computer behave like it is good for nothing.

Having a Restore point can help windows users, and you always have an option to take your PC back in time when your System was working like butter.
