Digital Transformation

 Digital transformation is not simply duplicating existing processes in digital form; the in-depth analysis of how the business operates helps organizations discover how to improve their processes and operations, and harness the benefits of integrating data science into their workflows.

Most organizations realize that digital transformation will require fundamental changes to their approach towards data, employees, and customers, and it will affect their organizational culture. Digital transformation impacts every aspect of the organization, so it is handled by decision makers at the very top levels to ensure success.

Why and When Should One Start Learning C#?

This post may be interesting for those who are just thinking of starting to learn programming, but are afraid to take the first steps because of the difficult, according to some opinions, theory.
For those who are willing to master a new sphere of knowledge and apply it in work – I’ll just mention – it's never too late to start learning – let it be programming or something else! If you have the motivation, desire to learn and the chosen subject area – just start learning!
Here, I’d like to tell a couple of words in favor of C# (C Sharp) technology. In the other articles, here at my blog, you may read professional materials on C# programming.
Now, let’s figure out why one should consider learning C# programming language?
     C# is a fairly young programming language. It appeared about 14 years ago and derived from C. So, it is a modern programming language, which gives the specialist, mastered it, an advantage on the IT market. Besides, there are a huge number of powerful libraries, tools for unit testing, and whatever else you need to create C# code.
     Unlike C, which is a low-level programming language, C# is a high-level language and the one easy to start with (in my opinion).
     C# is an object-oriented programming language. It gives the programmer a possibility to work on a high level of abstraction, which makes work much more effective. You don’t need to bother about memory allocations and many-many other low-level problems.
     It is extremely popular in different areas, based on C# you can create games, desktop application, and websites.
     C# is on 9 positions higher that Java and on 7 positions higher than C++ in a Most Loved programming languages category in Stackoverflow Developer survey.
This list of C# benefits may be continued, you are welcome to leave your vision on this topic in comments below the post.
Talking about learning C# for absolute beginners, there are many ways to do this:
1.      A professional approach is to apply to university program for Computer Sciences, where you’ll study all related subjects.
2.      Apply for a paid course, where a coach \ teacher – former or a current software developer will teach you with a group of people, and share his experience and knowledge.
3.      Start online programming course yourself. It may be a free or a paid one, you can find a bulk of them on the Internet. Here, I’d like advice free C# tutorial for absolute beginners – Codeasy.net, where you learn while reading an adventure story and fight with machines side-by-side with the characters of the story. It may be a good start for complete beginners, who are afraid of dry and complicated technical theory. Besides, this tutorial has practical tasks, so one can practice coding while reading the story. 

No matter which way you’ll choose, if you have the desire, hard working will lead you to success. Even if you want to try yourself as a programmer for self-development or as a hobby, then it's certainly never too late.

PHP and MySQL tutorial

PHP is the most popular scripting language for web development. It is free, open source and server-side (the code is executed on the server). MySQL is a Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). It is also free and open source. The combination of PHP and MySQL gives unmet options to create just about any kind of website - from small contact form to large corporate portal.

Water or liquid Damaged phone: Whats to do? How to recover phone? What i...



What you should do if your phone drops in water?
And how to recover phone?
What is physics underneath it?

One question that asked several times to me is that what's to do, when phone drop in water, tea, coffee or something similar or these things are poured onto the phone. Is this damage yours phone? You will shock to know that, water is a main component used in fabrication of these phones and its tiny components and ICs. So why these phone, damages with water? And, how will you recovered damaged phones?

In this video I will show you how the water damages the component on the board. And why Samsung is more resistive to this damage. The IC's on Samsung phone are sealed. And there is less probability of entering water underneath the IC. The BGA ICs are more sensitive to water. You will shock to know that these IC are cleaned with water before packaging. So why water create problem here. The problem is created by water itself. During fabrication De ionised water is taken whose conductivity is very low. But the water that we use in our home has sufficient conductivity. And when it stuck under these IC's, the BGA connects are shorted. This will damage the IC or the component attached to these IC's. In worse condition the water underneath boils due to power voltage across the BGA balls. And that expansion torn the IC's pin-outs from the board. So only drying the board, completed the recovery process. You have to take out all of the water underneath the ICs. This can't be done, either by putting phone in Rice or Tea, or by compressed air. Now there is one catch here, dry the board in your hand this will limit the temperature. Because excessive heat boils the water underneath the IC and thus create a pressure underneath IC, this will, either break IC or torn the contact pads on PCB. So go slowly.
