How to Effectively Debug Your Code

Damjan Dimitrov — Mon, 10 Apr 2023 08:38:08 +0000

Debugging is an essential skill for every programmer. No matter how carefully you write your code, bugs can and will inevitably find their way into your applications. In this article, we'll explore some tips and tricks for effectively debugging your code.

Use a debugger

Debuggers are tools that allow you to execute your code line by line, set breakpoints, and inspect variables and objects at runtime. Most modern programming languages and IDEs come with built-in debuggers, and there are also third-party debuggers available for many popular languages. Using a debugger can be an incredibly powerful way to pinpoint the source of a bug in your code.

Reproduce the bug

Before you can effectively debug a bug, you need to be able to reproduce it reliably. This means understanding the conditions under which the bug occurs and ensuring that you can trigger it consistently. Once you've identified the steps needed to reproduce the bug, you can use the debugger to step through your code and find the root cause of the problem.

Write automated tests

Automated tests are an essential tool for any software development process, but they can also be incredibly helpful for debugging. When you encounter a bug, write a test case that reproduces the bug, then use the debugger to step through the code and find the root cause of the issue. Once you've fixed the bug, the test case can be added to your automated test suite to prevent the bug from recurring in the future.

Use logging

Logging is another powerful debugging tool. By logging relevant information at strategic points in your code, you can get a better understanding of how your code is executing and identify areas where bugs may be occurring. Logging can be especially helpful for debugging issues that occur in production environments, where you may not have access to a debugger.

Break the problem down

When debugging complex issues, it can be helpful to break the problem down into smaller, more manageable pieces. This can help you isolate the source of the bug and make it easier to fix. Start by identifying the inputs and outputs of the code in question, then work your way through the logic step by step to find the source of the problem.

Conclusion

In conclusion, debugging is an essential skill for every programmer. By using a debugger, reproducing the bug, writing automated tests, using logging, and breaking the problem down, you can effectively debug your code and solve even the most complex issues. By using these tips and tricks, you can become a more efficient and effective developer, and produce higher-quality software.

Best Practices for Writing Clean and Maintainable Code

Damjan Dimitrov — Thu, 12 Jan 2023 20:00:50 +0000

Clean and maintainable code is essential for any development project, whether it's a small personal project or a large enterprise application. In this article, I will share some best practices that I have found to be effective in writing clean and maintainable code.

1. Use descriptive and meaningful variable and function names

One of the most important principles of clean code is that it should be self-explanatory. Using descriptive and meaningful names for your variables and functions is essential for making your code easy to understand. Avoid using abbreviations or single-letter variable names, unless they are commonly used in the industry (i.e. i for index)

2. Keep your functions short and focused

Functions should have a single, clear purpose. If a function is doing too many things, it can be difficult to understand and modify. A good rule of thumb is to keep your functions small and focused, ideally no more than 20-30 lines of code.

3. Use comments sparingly

Comments are an important tool for explaining the intent and functionality of your code. However, it's important to use comments sparingly and only when necessary. Comments that simply repeat the code or are outdated can actually make your code harder to understand.

4. Follow a consistent coding style

Consistency is key when it comes to writing clean and maintainable code. Using a consistent coding style makes it easier for other developers to understand and work with your code. Most languages have widely accepted coding standards, such as PEP8 for Python, you should follow them.

5. Write tests

Writing tests for your code is one of the best ways to ensure that your code is clean and maintainable. Automated tests can help you catch bugs and regressions early, and they also serve as documentation for how your code should be used.

6. Refactor your code

As you work on a project, it's important to take the time to refactor your code. Refactoring is the process of improving the structure and organization of your code without changing its functionality. This can help you make your code more readable, maintainable, and efficient.

In conclusion, writing clean and maintainable code is essential for any development project. By following the best practices outlined in this article, you can help ensure that your code is easy to understand, modify, and maintain. Remember, it's not just about getting the job done, it's about doing it well.

Short oneliners: Create array of hour interval strings

Damjan Dimitrov — Mon, 29 Nov 2021 13:15:11 +0000

This is a way to get an array of hours in a day in the HH:mm format:

Array.from({ length: 24 }, (_, k) => k + 6).map(el => `${String(el % 24).padStart(2, '0')}:00`);

Result:

Array(24) ['06:00', '07:00', '08:00', '09:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00', '20:00', '21:00', '22:00', '23:00', '00:00', '01:00', '02:00', '03:00', '04:00', '05:00']

We can change the start time by changing the "k + 6" increment amount, or also include the same starting hour in the next day by changing the result length to 25.

Have you tried the GitKraken CLI feature yet?

Damjan Dimitrov — Sun, 14 Nov 2021 16:14:38 +0000

For those of you who don't know yet about GitKraken, it's an awesome Git GUI client which has an abundance of neat features which facilitate your git workflow, increase productivity, offer clean repository visual overview, save time and make you feel legendary.

This allows for the developers who are keen on using the terminal for git commands to be able to continue using the terminal for their git workflow while still being able to keep an eye on the visual element of the repository.

With GitKraken's stunning, modern and colorful UI you are able to preview the commit and branch history while working in the CLI. This allows you to synchronize your command workflow with the visual aspect of the current state of the git repository. The command line is shipped with many helpful features in itself such as a diff view, history & blame view and autosuggest.

Make sure to check it out if you haven't already as well as GitKraken's Git GUI client. It is free to download for any platform, though it also includes pro and enterprise plans which include many other integrations too.

Completing my second Hacktoberfest (2021)

Damjan Dimitrov — Sun, 17 Oct 2021 15:38:11 +0000

Intro

I have successfully completed this year's 4 pull requests to contribute towards the open-source code and community and engage in Hacktoberfest of this year. Just like last year it was a very good experience and was even easier after already being familiar with the rules and workflow from last year.
I enjoy getting to contribute to some cool open-source projects and helping them grow, as well as improving my skills and learning something new in the process.

Contributions

This year I focused more on projects' maintenance rather than building new features or fixing bugs like I did last year. I realized many projects lack the required maintenance due to the fact that it's often overlooked by other hacktoberfest participants as dull or insignificant. In other words, I decided to do some "dirty work".
On two repositories I contributed by migrating their package, library and dependency versions to the newest versions. This had not been done for a long time due to the fact that the upgrades introduces many breaking changes which required time and effort to be fixed and adjusted. I did just that, and I think it is important to keep all dependency versions up to date often not just because of new updates but also because of security concerns.
In my opinion my best contribution was to

bemusic / bemuse

⬤▗▚▚▚ Web-based online rhythm action game. Based on HTML5 technologies, React, Redux and Pixi.js.

which is "an open-source, online, web-based rhythm game. It plays songs in BMS format".
I contributed by updating and refactoring a large chunk of code in a file which had numerous code smell reports from SonarQube. I successfully managed to fix the code smells and refactor the code such that it was more readable, manageable and did not contain any code smells.

Conclusion

My experience this year was again very thrilling and I'm excited to be a part of an amazing open-source initiative. I encourage anybody who is having self-doubt or second thoughts about contributing to open source to step out of the shadow and make their first step towards open-source. It is intimidating at the start but it's very much worth the effort. It is important that we have this kind of initiatives that remind us how great open-source can be and keep us motivated to support many more open-source projects.

How wakatime motivates me to stay productive

Damjan Dimitrov — Sun, 20 Sep 2020 10:14:37 +0000

For those of you who don't know, wakatime is a plugin that can be integrated into an IDE (or browser) to keep track of how much time you spend coding, as well as showing time spent for different languages and projects. I use it on all my IDEs such as Visual Studio, Visual Studio Code and others which I use on a daily basis.

Wakatime gives me the satisfaction of getting to see and measure how productive I was during the day or the whole week (could be even the month or longer). It truly feels great and fulfilling to see how focused and "in the flow" I really was throughout the work week.

For anyone interested I really recommend using Wakatime, it is free and very simple and it supports many IDEs, editors and integrations.

I also have set up a very cool github profile readme using a GitHub action provided by avinal, you can check mine out on my github profile dimitrov-d

Python Scheduler: A cron job replacement

Damjan Dimitrov — Fri, 15 May 2020 18:14:47 +0000

In this post I would like to show you a more convenient way of scheduling tasks to execute on a given time period.

Cron jobs are commands which are performed in a set time interval, it can be every minute, every hour, every third day, once a week etc.
Sometimes the process of creating and setting up a cron job might appear to be tedious and complicated. I've found an awesome python module for doing exactly what a cron job does but in a way cooler and more fun way.

The module is called schedule and according to its official documentation, it is designed to be very understandable by a human. Here's how it looks:

Now, let's say we have a real life problem we need to solve and keep doing that periodically. As an example, I've made a script which checks for empty folders in a given path. This might appear to be a mess for someone who forgets to delete empty folders, keeps rearranging files and other scenarios. This is how the schedule module looks like in action:

Now, the last thing we need to consider: the scheduler is running only as long as we have our program open and running. When we close or stop the program, the scheduler is cut off and no longer checks for the time interval in the background.
As a solution for this, we can use the nohup command, which stands for no hangup and makes a process immune to hangups (in our case the hangup means stopping the script from running).
We have our scheduler.py file ready with the task we want to be executing in our timeline. These are the steps you should take in order to have the desired result:

Install the schedule module via pip by running pip install schedule , preferrably in your virtual environment
At the top of your script add #!/usr/bin/env python3 . This step is necessary if you have multiple versions of Python installed and /usr/bin/env will ensure that the first Python interpreter in your $PATH environment variable is taken.
In the terminal, run chmod +x scheduler.py , which will grant the required file permissions for continuous execution
Run the command nohup /path/to/scheduler.py & . The '&' symbol ensures that your script will run in the background as a system process.

Congrats, you now have your script running in the background. You can feel free to close the terminal and do something else while your script will check for the time period uninterruptedly. If you want to stop script from running, you can list the processes and find its id with the command

ps ax | grep scheduler.py

which shows you the process' PID and then run

kill PID

Note: This was developed and tested only on a MacOS system

I created a Java Chat Bot!

GitKraken - The tool I can't git without

Damjan Dimitrov — Tue, 11 Feb 2020 08:44:06 +0000

We have all been there at the beginning of learning git - jumping through courses and blogs, reading documentation, trying to learn commands by heart, practising etc. I was there too, struggling to get a grip of what git actually is and how it works. I am willing to present you GitKraken, the tool which will save you an unimaginable amount of time which you would have spent on re-reading git documentation or strolling through some git cheat-sheets.

This tool is amazing and I cannot enjoy it enough. It provides all the features git has to offer in just a click away. It has a beautiful colorful representation of the branches and their flow, as well as a toolbar with all the commands you constatly use.

It also has a sidebar to view all your existing local and remote branches, and offers all of the necessary options you need to work with them.

My favorite part of using this git tool: The diff view. It feels so empowering to be able to see the changes in the repo with a neat diff tool. This is another thing that GitKraken offers. It offers three different diff views, one of which lets you discard od stage only chunks of a modified file, you can clearly see who has worked on these changes and list all the files which have been modified. Besides this it has a very similar and interactive conflict resolver GUI as well.

Additionally, GitKraken has some other features called GloBoards and Timelines (NEW), which you can use for issue tracking or project/task management and tracking current milestones. It is also a part of the Student Developer Pack, from which as a student you can get a free PRO account for a whole year.

I very much recommend using this tool to everyone who is working with git on a daily basis and does not feel as cool about manually typing commands in the terminal as in the beginning. You can read more about GitKraken here
