Want to make a career out of programming in 30 days? Here are the things you need to know and the path you need to follow.

What are Computer Programming Languages?

Programming languages are just like human based languages, they are a set of languages that humans can use to communicate to computers, the portion of the language that computer understands is called a binary when the commands given to computer is translated to binary is called compiling, every language that exists taking the example of python to C have their own unique features although some times there are things that are in common.

These languages that are a piece of machine intelligence allows computers to process large and complex bulk of information in no time for example, if a person is given a list of random human names and is asked to place them in alphabetical order, chances are that it will take a good amount of time and will include number of errors.

MAKING A CAREER OUT OF PROGRAMMING LANGUAGES:

Programmers are a type of architects, digital architects you can say to be precise who give their time and effort to create new and amazing technologies and it is a fantastic profession, and you have probably found yourself thinking, sitting on your couch, wondering how to become a programmer.

Take a deep breath and give it a thought about all the online things you have done today like all tech-savvy people out there, you have probably checked your emails, scrolled through your social media and browsed through your favorite websites, but have you ever imagined that the virtual world that you visit every day and go by in seconds is the result of hours long full of fatigue programming work.

Programming is a fantastic career path with great potential for growth, especially since so much of our lives are now lived online and here are some statistics to prove you that

The Bureau of Labor Statistics reports that the profession will grow by a full 13 percent between 2018 and 2028 twice the average rate of growth expected for all other occupations. 

According to PayScale, the majority of programmers feel happy about their success, confident in their skills, and secure about their financial futures; the profession enjoys a 4.5 ranking (out of 5) for satisfaction.

Perhaps you also wish to be a part of this community. If yes, here are the 5 steps you can follow in becoming a successful programmer:

  1. Decide Which Industry You are Interested In
  2. Identify the Languages You Need to Learn
  3. Start Learning Independently
  4. Start Your Own Projects
  5. Begin Looking for Jobs

Top 10 programming languages:

1. Python

 Python is greatly regarded as a programming language that is easy to learn, due to its simple syntax, and a toolkit, in fact, it’s the first language that many students learn in the field of programming.

2. JavaScript

JavaScript is the most popular programming language for building interactive websites.

3. Java

Java is the programming language most commonly linked with the development of client-server applications, which are used by large businesses with masses of data around the world.

4. C#

 Microsoft developed C# as a faster and more secure variant of C. It is fully combined with Microsoft’s .NET software framework, which supports the development of applications for Windows, browser plug-ins, and mobile devices.

5. C

 Along with Python and Java, C forms a “good foundation” for learning how to program, As one of the first programming languages ever developed, C has served as the foundation for writing more modern languages such as Python, Ruby, and PHP.

6. C++

 C++ is an extension of C that works well for programming the systems that run applications, as opposed to the applications themselves. C++ also works well for multi-device and multi-platform systems. Over time, programmers have written a large set of libraries and compilers for C++.

7. Go

Also referred to as Golang, Go was developed by Google to be an efficient, readable, and secure language for system-level programming. It works well for distributed systems, in which systems are located on different networks and need to communicate by sending messages to each other. While it is a relatively new language, Go has a large standards library and is taking over the market rapidly.

8. R

R is heavily used in statistical analytics and machine learning applications. The language is extensible and runs on many operating systems. Many large companies have adopted R in order to analyze their massive data sets, so programmers who know R are in great demand. 

9. Swift

Swift is Apple’s language for developing applications for Mac computers and Apple’s mobile devices, including the iPhone, iPad, and Apple Watch. Like many modern programming languages, Swift has a highly readable syntax, runs code quickly.

10. PHPs

PHP is widely used for server-side web development, when a website frequently requests information from a server.

How to undo the last git commit?

by Muhammad Jawaid Shamshadin BitBucket, Git, Source ControlLeave a Comment on How to undo the last git commit?

There are situations where you just committed a change in git and just after that realized you made a mistake in the last commit. If you haven’t pushed that code then the last local changes can be undone with the following command.

git reset --soft HEAD~1

What this does is that it uncommits the last change and puts that back in a staged state. That means if you run the git status command then you will see those changes in your working directory. Now you can make further changes to that revision and then commit again.

Why database should be taught before programming in universities

by Muhammad Jawaid Shamshadin .Net, Android, AngularJS, ASP.Net, C/C++, C#, Database, HTML/CSS, Javascript, jQuery, MS SQL Server, MySQL, Oracle, PHP, Ruby, Web Development, XMLLeave a Comment on Why database should be taught before programming in universities
Learn Database before Coding

Often students from initial semester ask me how do we store our data in our programming project? When students join university to learn about computer science and technology they are usually taught programming first in courses like introduction to programming. As part of coursework students are required to work on a project. Majority of the projects, in fact almost all projects involve data handling and that data needs to be stored somewhere.

Problem students face

As a novice students don’t know how to store data. One option is to store data in plain text files if filing is taught to them but in that case their project becomes too complex for them. In my opinion, file formats is an advanced topic for students that have just started learning how to program. So, students get stuck where and how to store data. They create variables and arrays to store data in memory but that is not very useful until they have option to store their data somewhere permanently that they can retrieve later. Otherwise, every time they run their project they have to feed data from the beginning.

Teach Database before Programming

If universities modify their courses and add database in first semester and replace programming course with it then it would be easier for students to get started in computer science degree. Introduction to database is relatively easier course then programming and students will know what is database, how to store data in database, and how to retrieve it later using SQL. Then in next semester if they do a programming course then it will require only one lecture to teach them how to access database from your code and how to store and retrieve data. That will not only make their projects more valuable but will make more sense to them and they can take it to advance level in forthcoming courses.

Creating Git branch in detached HEAD State

by Muhammad Jawaid Shamshadin BitBucket, Git, Source ControlLeave a Comment on Creating Git branch in detached HEAD State

Recently, I came across a situation where I checked out a git branch and it showed me this message:

You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout.

I guess this happened because the branch that I was checking out was rebased. Otherwise, it usually happens when you checkout a commit with its hash. But in my case, I was checking out a branch. Anyway, this is a special state called “detached HEAD”. While you can commit changes in this state, those commits don’t belong to any branch and will become inaccessible as soon as you check out another branch. But what if you do want to keep those commits?

The answer, unsurprisingly, is to use the “checkout” command again and you can use the same branch again:

git checkout <branch> #now you're in detached head state
# do some work and stage it
git add --all
git commit -m "add some work while in detached head state"
git branch <branch>
git checkout <branch>

Pretty easy, right?

Mounting NFS Share on Windows 10 & 11 with Write Access

by Muhammad Jawaid Shamshadin Linux, Microsoft, RedHat, Technology, Windows4 Comments on Mounting NFS Share on Windows 10 & 11 with Write Access

It is easy to mount a drive from Linux NFS share on Windows 10 & 11 machines. To do that make sure you have NFS Client (Services for NFS) is installed from Programs and Features. Following is the command to mount the NFS drive. Note that this command will run on cmd (Command Prompt) and not on PowerShell.

mount \<IP_ADDRESS>\<PATH_TO_DIR>\ drive:

For example, if the IP address of the NFS share is 10.235.0.10 and the directory you want to share is /var/www and you want to mount it to your Z drive, then you can run the following command.

mount \\10.235.0.10\var\www z:

But when you mount the drive you can browse the files using your Windows Explorer but you cannot create new files nor edit any files. To get write access on NFS share you have to make a small change in Windows registry before mounting the drive. Follow these steps.

  1. Open regedit by typing it in the search box end pressing Enter.
  2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default.
  3. Create a new New DWORD (32-bit) Value inside the Default folder named AnonymousUid and assign the UID found on the Linux directory as shared by the NFS system. This is the UID of the user that has the write access to that directory on Linux system.
  4. Create a new New DWORD (32-bit) Value inside the Default folder named AnonymousGid and assign the GID found on the Linux directory as shared by the NFS system. This is the GID of the group that has the write access on the directory on Linux system.Windows 10: Regedit NFS AnonymousUid and AnonymousGid
  5. Restart the NFS client or reboot the machine to apply the changes.

Now run the mount command and you will get the write access.

Mark parent category menu active on single custom post view in WordPress

Recently I developed a theme for one of my client and I had to highlight the menu item of parent category in main menu when one of its associated single custom post is viewed. For that I had to add an action in my functions.php file for nav_menu_css_class. What is does is it returns the ‘active’ class which WordPress adds to the parent category menu item in the main menu. You can see the code at Gist here.

Why we moved from OpenShift to Google Cloud

by Muhammad Jawaid Shamshadin Cloud Platform, Google, Linux, OpenShift, RedHat, Web, Web DevelopmentLeave a Comment on Why we moved from OpenShift to Google Cloud

The good old days

When OpenShift was in its version 1 it was great from customer’s point of view with low budget. OpenShift v1 had free offers to deploy app and add a custom domain to it. There was no SSL support but it could be handled via CloudFlare solution, making overall solution a great one.

Then there comes OpenShift v2

RedHat then launched OpenShift v2 and added a restriction that gears will be shutdown after certain period of inactivity and also removed the support for custom domain.

That was the time that we had to move to some other cloud platform that could support our apps with low resources and without investing anything.

Since all good things in life are free.

Google Cloud to the rescue

So we came across Google Cloud platform offering and we had $300 credit in free trial for next 6 months. That was more than enough for us to start with. And in fact they have micro virtual machine instances that are free for life with 30gb storage. That is more than enough for small apps to run for free that are under experiments or don’t have any monetization plans.

So, we migrated several of our apps from OpenShift to Google Cloud and started leveraging free credits provided by Google.

Just this week we consumed all our credit and our trial expired. Our virtual machine instances were shutdown, but it didn’t take long that we enabled billing on our project and downgraded our instances to micro ones which is free. That gave us such a relief that our apps are still running although with low resources but it is fine as that are not our revenue generating apps and are just experiments.

Codenvy and BitBucket Integration

by Muhammad Jawaid Shamshadin BitBucket, CI/CD, Docker, Source ControlLeave a Comment on Codenvy and BitBucket Integration

OK, this post is a quick one. Let’s go.

In your Codenvy workspace goto Profile > Preferences > SSH > VCS and generate key and give it a name bitbucket.org. This will generate key for you. Copy this key by viewing it which we will use later on BitBucket.

Now go to BitBucket, select your repository, and then goto repository settings. Under Access Keys menu click Add Key button. Give a label as bitbucket.org and paste the key copied in previous step here and save.

Now on Codenvy project goto Git menu and add remote. You need to give SSH url to your BitBucket repo here. Add it and you can now pull the repo from BitBucket. Awesome!
