Sometimes our application collects more logs than we would expect. Especially in the case of endpoints responsible for the server status. Thanks to a simple plug, you can inform about the system state all the time without logging this request.

The Twelve-Factor App methodology is a methodology for building software-as-a-service applications. It allows you to eliminate the most common problems with our applications. Some of them have already become the industry standard, so you should get to know them all. The methodology constitutes design guidelines strongly focused on cloud-native, portable, and resilient applications.

Selling is not an easy job. The customers don’t care about you. What matters is how you can solve their problems. People often recommend and buy from people they know well, like, and trust. See how to use the KLT principle in your business.

Freedom of choice is often the biggest curse. Sometimes the basics are enough, and the rest is just an addition. Don’t overcomplicate, don’t add maintenance, and keep it simple to be less sensitive.

When connecting to the server with SSH, you may need to use a certificate other than the default one. Additionally, often the username is also more complicated. How do you remember it all? Special configuration file that will help us solve the problem.

Protecting confidential data is a daily task. Thanks to a good web browser, a strong password, and other security measures, you can mitigate the risk of your identity being stolen. Use this personal security checklist to be even more secure!

Guards are a great way to check data limits. They are safe and can make the everyday work with the project more pleasant and, at the same time, limit the duplicated code. And it’s all in pattern matching!

One of the possible vectors of an attack on the system is the disclosure of the used keys, certificates, or other access data. I found TruffleHog as a tool to verify your project. The tool can scan projects on GitHub or GitLab, including entire organizations! You can attach them to your CI/CD pipeline to verify that no confidential information has been published.

JSON Web Tokens known as JWT, are a great way to ensure security in communication between system parts. Remember not to trust the user and verify the data before use. JWT contains a lot of information about the user and his permissions. It is also a well-thought-out structure. It indicates in an accessible way for whom and by whom the token was prepared. Also, check out the topic of key rotation and its benefits.

Feeling overwhelmed by work is quite a common feeling. Especially if we work on the project for a long time. Good planning can make your work more pleasant and simplified. You don’t have to complete all tasks (alone). Some tasks can even be removed. With the Eisenhower matrix you can manage your priorities.

Error handling is an integral part of any project. However, only a few can do it well. What makes an error message good? Take care of the language of the message, its length and indicate how to mitigate errors. Have automatic bug reporting tools to quickly respond to system problems.

I would like to present some useful tricks to speed up your work. Elixir’s interactive shell is a great tool to make your work comfortable. You don’t need to use a browser to check function errors. You have everything available in the console!

One of the advantages of Elixir is its openness. You can get more readable code with the command wrapped in tuple. You don’t need to modify the response from functions itself.

The presentation of extra details about your website is straightforward. All you need to do is use Open Graph protocol. Any web page can become a rich object in a social graph. You can use it to show a thumbnail, author details, or even a short description.

You can use Ecto to check any information from the user. Extra, we have another layer of security. Only the supported parameters are passed to the domain layer. Using Ecto to verify parameters from the user is not difficult and can be part of your API verification pipeline.

A lot is happening in the IT world. Instead of jumping from one topic to another nervously, it’s worth concentrating on one thing. Stop for a moment and identify the problems. Also, remember that there is no right way in life. One is faster, and the other is slower. Don’t be afraid to ask for help.

Elixir 1.12 introduced two very useful macros. They can be life savings helpers in your codebase. Instead of write extra functions, you can have nice logging and executing actions based on given data.

Users often do not see the dangers of a weak password. Often, they reuse the same passwords on different sites to make their daily lives easier. Security is one of the critical aspects of any project. With Have I Been Pwned? it is possible to check passwords based on various leaks.

Not so long ago, to release the application, it was necessary to modify the binary files on the servers. Thanks to good DevOps practices, the entire process can be changed. It is possible to achieve tens or hundreds of releases each day. Everything without the downtime of the application.

Start from understanding the needs and point of view of the organization. Take care of good communication with customers. Don’t be afraid to develop both technical and soft skills. You will have a lot of battles at work. Choose wisely what you can engage in, given your limited time capacity. Act locally, think globally to change the project in small steps. Use non-hanging fruit to be successful and avoid burnout.

In my opinion, the best investment is our development. It allows us to achieve better results, receives promotions, and increase our remuneration. By investing in ourselves, we invest in our future. You didn’t know everything (and you still don’t know everything). It is worth trying to help others and learning at the same time.

Many applications introduce some kind of status to make it easier to share data. However, more and more modules in your codebase need to be explicit about these assumptions. Views can eliminate the problematic SQL query. It’s also great way to introduce well-defined entities.

Understanding the business is critical. It allows you to achieve better results in a shorter time. Don’t try to be an expert right away. Learn and don’t be afraid to ask when something is unclear. A common language is an opportunity for discussion with the client.

Automated testing can unburden Quality Assurance teams from the monotonous manual review of every change. They can also be a great acceleration for programmers. But they won’t make your organization or product great overnight. It would help if you had people’s support, a clear plan, and an understanding of expectations.

The more time we have to do the job (especially in the office), the longer it takes. Work complicates to fill the available time. Check out Parkinson’s Law and understand why!

Don’t be afraid to make mistakes. Even the best programmers make mistakes. However, minimize their impact and react quickly to the most critical problems. It is much better to make mistakes but fix them quickly than to delay the development phase and not provide functionality.

We have a new version of the most popular Elixir framework - Phoenix framework. New generators, fixes and improvements are now available. Find out more about the new HEEx engine.

A good recruitment process starts with a personalized message selected for a specific candidate. Worth mentioning which technologies are used in the project. Try to keep the first conversations short but very meaningful so that neither party feels like wasting their time.

Try to use setup_all to prepare the data once and re-use it in tests. Use tags to have a better context and be able to exclude some tests. Prepare a processing pipeline to check the quick tests first, and when they do not fail, take care of the more time-demanding tests.

Code review can be an opportunity to sharing knowledge. Finding errors is a side effect of the entire code review process. Thanks to code review, you can promote one standard style of changes to the entire team. Don’t be afraid to ask if you don’t understand something.

Have you thought about the response statuses of your endpoints? Some of them can be used for scanning your architecture. Some attacks on IT systems target the weakest areas, which may be addresses used for internal purposes.

Instead of focusing solely on our business, we should try to understand the client’s expectations. Your client’s success is your success. A satisfied customer is our primary source of recommendations. Treat others as you would like others to treat you.

We expect our estimates will have a positive impact on the implementation. The most significant value of the estimation is not the value itself. It is a better understanding of the project, and a consistent view of the tasks carried out.

It is not always possible to be right every time. It didn’t really matter who’s the solution was chosen. What counts for the customer is a well-implemented project that meets his expectations.

GitHub Copilot tries to understand the programmer’s intentions and generate the code closest to the expectations. Aside from generating code, understanding the programmer’s intentions can be a much bigger problem. The use of the code created by this tool remains controversial.

Companies often create strategy plans called roadmaps. In the case of a personal roadmap, the plan is for a specific person - you. It can be a great way to achieve your goals and expectations.

We don’t touch the code in our projects with equal frequency. The tool for automatically discovering candidates comes in handy by identifying the most frequently modified files with high cyclomatic complexity. Then we can focus on these files and make changes to work with better codebase.

Knowledge sharing can be a great way to grow faster. It’s also an excellent opportunity to build the image of the expert. There will always be someone we can help. Our knowledge can be helpful and a huge step in personal development.

Developers and business misunderstand the concept of technical debt. Building on weak foundations can result in losses and risks to your business. Instead of talking about debt, we should talk about missed opportunities.

Taking notes and summaries of meetings can provide a better engagement in discussions. Notes can also be a source of truth and a good reference while working. Do it on paper or immediately digitally, depending on your preferences.

You don’t want to postpone tasks? The best way is to change your approach and set the time window for the project. Instead of dividing up into tasks and thinking about everything right away, you can accomplish as much as you can.

We spend most of our life at work. Work should not be a place where we are forced to go. Have you considered the enemies of our work? Blame culture, ego, responsibilities - these are only some of the topics worth paying attention to.

I love podcasts because they can change a lot in our lives. Recently I was analyzing one, and I would like to share something that seems extremely important to me.

Recently I came across the topic of learning and documenting progress. Sharing our development with others can be done in many ways. I want to share my opinion about the advantages I see.

Daily work provides many situations to upset, surprise, and even laugh. I asked my friends who are programmers what annoyed them. Please don’t take it as a complaint, but rather as an opportunity to change.

Most of our projects use databases. We often do not realize that incorrectly used functionality may block our applications. Simple changes can save us from unpleasant consequences.

No project is perfect from the start. The real problems are very complicated. While something seems simple and fits perfectly, it may not be. I want to present the most critical and unchanging aspect of each project.

Changing your job or team often means changing the current project. It can be a difficult situation for most, especially at the beginning. The first impression can only be made once. It’s worth doing it right. See what we should do to get noticed at a new project.

Everything around us makes us concentrate on what is available immediately and instantly. Short-term gains and results are much more appreciated than long-term with much better results. Long-term thinking and acting following this thought is the key to a peaceful life on your own terms.

A good recruitment process starts with a personalized message selected for a specific candidate. Worth mentioning which technologies are used in the project. Try to keep the first conversations short but very meaningful so that neither party feels like wasting their time.

Personal branding is not only social media and a broad group of followers on Twitter or LinkedIn. It is the opinion of others about us and our suitability for a given topic. Building personal branding is a long process.

Since you can’t manage time, let’s try to manage yourself in time. Avoid multitasking, focus on one activity, and try to do the best you can. Group tasks into blocks to reduce context switching. Remember that meetings can be tiring.

Time can be the best gift our loved ones can receive. It’s you who gets to live your one and only life. Don’t let people who won’t ever live with the consequences of your choices determine how you spend your time.

You don’t want to postpone tasks? The best way is to change your approach and set the time window for the project. Instead of dividing up into tasks and thinking about everything right away, you can accomplish as much as you can.

The New Year is an occasion for new resolutions. Most often, they are only for a while. What influences our resignation? What should we do to increase our loyalty?

When I’m developing outside of working time, I like to collect addresses of visited websites. After a long time of collecting it by hand, I decided to change something. With Chrome Extension, I can do it automatically!

We spend most of our life at work. Work should not be a place where we are forced to go. Have you considered the enemies of our work? Blame culture, ego, responsibilities - these are only some of the topics worth paying attention to.

Remote work, productivity, and time management are important topics. I want to explore the topic of increasing productivity while working from home. Check out my way of better commitment and the opportunity to focus on work duties.

No project is perfect from the start. The real problems are very complicated. While something seems simple and fits perfectly, it may not be. I want to present the most critical and unchanging aspect of each project.

A blog is a great way to learn from your past. You can be your own teacher. Let me show you why I started my blog.

Companies operate in an uncertain environment. Uncertain technology is certainly not something that will interest them. What makes companies decide to use Elixir language?

Most of us have moved from working in the office to working from home. For most, this was a new and unexpected situation. Reflecting on the topic of remote work, I wanted to prepare a list of activities that will allow us to avoid lack of concentration, constant monotony, and being at work 24 hours a day.
