According to App Annie, the mobile game industry is expected to generate $100 billion in revenue in 2020, up from $86 billion in 2019. Over the decade, gaming apps have evolved in terms of graphics, sound, and speed. Previously, mobile game development had a fixed plot. By that, I mean, if the gaming app was about racing, that’s all you could do on the app. However, technology today has enabled game developers to use various frameworks in order to customize characters, make squads, communicate, and so much more. Make sure that you develop a game that is hugely gripping for the user. However, the prerequisites to building a high flying gaming app begin with identifying your target audience. Consider executing market research in order to gauge your audience. Factors to consider when selecting your target audience: Area Age Gender With your target audience in mind, make a call. What kind of gaming audience do you have, and what do you want to develop for your audience? Game engines are mostly the softwares that run the game.

Though a wide variety of online and offline editing tools have been introduced in the market today, nothing can lessen down the importance and need of text editors. From editing a college essay, to writing long blocks of code, you can edit anything using a text editor.  Text editors are a dedicated program to open, view, and edit the plain text files and unlike the Word Processor, they do not add formatting to the texts. They are purely focused on editing plain texts. For example, if you are working on an Apple MacBook, the NotesApp can technically be regarded as your text editor on that system. If you are using a Windows-based computer, then a NotePad can be your basic text-editing program.    Now, before analyzing which text editor is better, let us first check out why text editors are so important?  The majority of features in all text editors are similar. Let us check some of them that are of immense advantage from a coder’s perspective:  · Like Word Processor, Text Editing software is easy-to-use and navigates easily.  · It has a ‘Find and Replace’ feature that helps you to change a single word in the whole file with a few clicks only.  · Cut, Copy, Paste feature is again similar to Word Processor.  · Unlike Word Processor, it can handle UTF-8 encoded text.  · Unlike Word Processor, it has a Syntax Highlighting feature that makes it easier to read code and pick up errors.  · It holds customizable appearance like modifying color schemes, font sizes, etc.  · It is scriptable and offers some plugin mechanism. It lets the programmer customize the editor with an additional feature.  Now, let us move to discuss the two premier Text Editing solutions available for all types of users.  1. Sublime Text    Sublime Text Editor though costs up to $80 for three years of span, but it also comes with a free trial. It works on all Mac, Linux, and Windows-based machines for business as well as personal usage. It is a proprietary cross-platform source code editor that comes with the Python application programming interface (API). It supports many programming and markup languages natively and allows the users to add functions community-built functions that are maintained under free-software licenses. The stable version 3.2.2 Build 3211 of this text editor is released on October 1, 2019.  2. Visual Studio Code    Visual Studio Code is a Microsoft produced source-code editor that works on Windows, Linux, and MacOS. It supports GitHub, embedded Git Control, debugging, snippets, intelligent code completion, syntax highlighting, and code refactoring features. The system is highly customizable and allows the users to change the keyboard shortcuts, theme, preferences, and install extensions that add additional functionality. It is a free and open-source text editing solution that has been released under MIT license.  Visual Studio Code can be used with a variety of programming languages. It is based on Electron – an open source framework that is used to deploy Node.js applications. The stable version 1.39.2 of the software has been released on October 16, 2019.  A small comparative analysis on this;  When Sublime Text is just a ‘text editor,’ Visual Studio Code is an exceptional Integrated Development Environment (IDE). Sublime Text is, though, an excellent framework that offers the quickest way to organize and write your code, it cannot debug the code. On the other hand, Visual Studio Code allows the programmers to both write and test code.  Sublime Text is best for beginners. It is quick and easy to write code and navigate throughout the interface. Visual Studio Code offers more hand-holding, but it is a perfect option for debugging functionality.  The above comparison is only based on few parameters. The best way to understand the software would be to download and give a try that seems suitable for your project.

I think clear coding is much more important than efficient coding. Long ago, the development arena was much more inclined towards making the code more efficient. The focus remained majorly on how much functionality can be packed into a single kilobyte of storage, how much RAM it uses, how tightly it complies, what extent of communication would be sent in every network packet, and so on. Those days, computers even fail to have random access to persistent storage and one program at a time could run. RAM was also measured in bytes than gigabytes. However, the time has changed now. Proficient programmers never ignore the efficiency of writing good code. But, now they also pay attention to the cleanness of the code. This mostly boils down to readability and comprehensibility that helps you in reusing the code. You will be required to reinvent the wheel many times. It would also be perfectly well if you decide to write the code from scratch than using whatever you have already written. Problems are similar whether you are working in an open-source or closed source environment. But when you know your own code, bugs can be easily fixed, and features can be easily added. When the code is clear, you will have a better idea of the sort of using certain functionality. This actually eliminates the need for rewrites. As long as your code meets the basic requirements for the efficiency needed to meet your requirements for the immediate future, clarity wins the race to efficiency. Even the coding experts suggest forgetting about the small efficiencies. Stop going to the premature optimization that reduces clarity in coding.

Yes, it is. However, there should be a question of how can you save software development costs?In this case start with defining better requirements. Obviously, your team will spend less time on meetings and evaluation of tasks if you define it weel. Define user needs, describe the expected behaviour and flow, discuss technology limitations and business value - you'll see it helps a lot.Prioritize right features and focus on value. Lack of proper planning and frequent changes in the roadmap (pivots) prolongs the development time (and it increases costs) because developers works on assumptions you provide. Every architecture and database can be changed, of course, but the question is the amount of work, which rises exponentially with the complexity of your solution.

401 Unauthorized requests

This error occurs when a visitor to a website wants to enter a restricted web page and is therefore not allowed to do so, usually a failure of a login attempt. In this error, a message indicates that for unknown reasons, the page could not load because of incorrect credentials.

Usually, this status is sent with a WWW-authenticate header containing information about how to correctly authorize. The 401 error code, like most error codes in the 400-range, indicates a client-side issue. In other words, the issue is on the side of the user's web browser rather than the page accessed.

Standard variants of the 401 error

  • 401Unauthorized 
  • Authorization Needed
  • Access Denied
  • HTTP Error 401

Fixing 401 in WordPress

1. Verify the URL

A 401 error may occur because you have wrongly entered the URL or have modified the login URL. It is possible that you may have clicked on your web browser's obsolete link. The server might display a 401 code in instances where a page does not exist. For spelling errors, review the URL. With the help of a search engine, you can validate the right web page URL that you are attempting to navigate.

2. Clearing stored cache & cookies 

The cache of your browser helps boost the overall browsing experience. Your browsers store local versions of the pages you access most often. The cache of your browser will often conflict with your application's live stream, resulting in a 404 error code. HTTP cookies are identical.

Just clear the browser cache and the cookies to correct this error and reopen the tab.

3. Disable the plugins of WordPress

Since WordPress plugins may change the functioning of your site, they are a typical source of WordPress's 401 error code. Firstly, deactivate all the plugins on your site and restart them one by one, and find out which plugin triggers the 401 error. If you are aware that the error occurred upon installing a new plugin, first uninstall that plugin.

4. Disable extra password protection from server-level

Try to disable additional secure passwords if you are using .htaccess to encrypt areas of your WordPress page with an extra username & password.

5. Flush the DNS

DNS errors may cause the server to display a 401-error code on your browser in unusual situations. You need to flush your Windows or Mac OS DNS to correct this. It is very easy to restore, but this is a fairly rare cause.

Before beginning to troubleshoot your problems make sure that your URL is correct and your cache and cookies are clear.

If you ask any programming wizard the secret to skilled programming, I can assure he will respond with this “ I am not a great programmer; I am just a good programmer with great habits.” It means writing clean code with minimum complexity. It applies to any software programs regardless of what technology the program is developed.Machine learning and data science involve applying some most complex logic.  For some programmers, it is still a puzzle to envisage simple coding structure and machine learning on the same page. However, with best practice, the code complexity in machine learning and data science projects can be minimized.  Ways to reduce code complexity in machine learning and data science projects1)  Implement clean code practiceThere is a well-known phrase among programmers “we will read more code than we will ever write”. Cluttered code makes it difficult to understand and modify. One common issue is keeping “dead code”  in the codebase. Removing dead code gives a clear visual of your code. Try to avoid print statements (even glorified print statements such as head(),df.describe(), df.plot() should be avoided).2)  Variable namesIn software programming, it is a bad practice to embed information about variable types in the variable name. One common problem in data science code is data frames (df). Every data frame is named as df. The good programming practice says, don’t force the reader of your code to translate what the variable means. Instead, try to use a naming convention that is easy to understand. See the example below, with Pandas Python library, the code is written in much human-readable form ( Code 2), and it gives a better idea about what the code is about compared to code 1. ( image source: towardsdatascience)Code (the same above code) declared with a name instead of “df”.  If you compare the above code with the below code, you can quickly figure out which one is easy to understand. ( image source: towardsdatascience)3)  Use functions to simplify code Function simplifies the code usage.  If ‘function” is declared wisely, then programmers don’t have to read each line or search the internet for things that they don’t understand.  Also, to repeat the same transformation on any column, a single line of code would do the job instead of writing lines and lines of code. 4)  Take code out of Jupyter notebooksJupyter notebooks are great for quick prototyping.

But it can make things more complicated as everything gets accumulated in one place. So, whenever a single line of code is changed, the entire notebook has to re-run. It means the longer the notebooks become, the harder it is to get feedback on whether our changes are working. The alternate way is to extract code into functions and Python modules, and have unit tests. With unit tests, the test runner can give feedback on the changes in a matter of seconds, even when there are hundreds of functions.5)  Adopt a test-driven development approachUnlike traditional software development, in test-driven development, you write a test for your code first, make sure it fails, and then create enough code to pass the test.  It means you are only focussed on passing the actual test and not writing code that is intended to pass all possible tests in the future. Once the developer has the code that passes the test, they can clean up the code, remove any duplication, apply good coding style rules, and add documentation. The TDD approach yields short cycles of fail-pass iterations. In the above points, we have mentioned the importance of functions, and the TDD cycle enables the programmer to write functions in small modules.6)  Make small and frequent commitsThe whole development process can greatly benefit from small and frequent commits.

Ways to reduce code complexity in machine learning and data science projects

1)  Implement clean code practice

There is a well-known phrase among programmers “we will read more code than we will ever write”. Cluttered code makes it difficult to understand and modify. One common issue is keeping “dead code”  in the codebase. Removing dead code gives a clear visual of your code.

2)  Variable names

In software programming, it is a bad practice to embed information about variable types in the variable name. One common problem in data science code is data frames (df). Every data frame is named as df. The good programming practice says, don’t force the reader of your code to translate what the variable means.

Code (the same above code) declared with a name instead of “df”.  If you compare the above code with the below code, you can quickly figure out which one is easy to understand.

3)  Use functions to simplify code 

Function simplifies the code usage.  If ‘function” is declared wisely, then programmers don’t have to read each line or search the internet for things that they don’t understand.  Also, to repeat the same transformation on any column, a single line of code would do the job instead of writing lines and lines of code.

With unit tests, the test runner can give feedback on the changes in a matter of seconds, even when there are hundreds of functions.

5)  Adopt a test-driven development approach

Unlike traditional software development, in test-driven development, you write a test for your code first, make sure it fails, and then create enough code to pass the test.  It means you are only focussed on passing the actual test and not writing code that is intended to pass all possible tests in the future.
