Find leaked credentials with TruffleHog

  • 1 min read

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.

Using JSON Web Tokens and their security

  • 3 min read

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.

Skills development as the best investment in life

  • 5 min read

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.

Using View as a way to simplify your system

  • 2 min read

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.

Automatic tests won’t solve all your problems

  • 4 min read

Automated testing can unburden Quality Assurance teams from the monotonous manual review of every change. They can also be a great acceleration for programmers.

Faster test execution in Elixir

  • 3 min read

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 is not for catching bugs
