Investigating the safety of MFA methods 🍼

Passwords would be great if people could use long unique ones. But they don't. So we need another measures to harden the security of software systems, which is MultiFactor auth. One of the methods is using text messages, but they are prone to be intercepted. Another way is hardware tokens, but you need to carry one with you. A solution in the middle would be usage of authenticator apps, which would bring the security of second factor, but reside on your mobile device. But are they secure enough?

Investigating the safety of MFA methods: are authenticator apps secure?
In this article we’ll take a look at the different types of MFA available and we’ll compare them from a security perspective. We’ll pose an important question: are authenticator apps secure? And we’ll explore how to keep authenticator apps safe to use as they evolve in the coming years.

Bun vs Node.js 👷‍♂️

Node.js is a widespread technology for Backend. It has it's own drawbacks like performance or requirement for external tools for working with Typescript.

How do databases execute expressions? 🤟

There are different approaches to programming languages; the same can be used for expression evaluation in database. Most databases use a tree-walking interpreter. A few use stack- or register-based virtual machines. A couple have just-in-time compilers. And, tangentially, a few do vectorized interpretation. What does that mean and what databases are considered - find it inside!

How Predictable is Communication Latency in the Cloud? 🤟

Network delays is a critical parameter in distributed systems. That's why it is important to understand how predictable latency is in Cloud providers depending on do you operate over the same subnet or doing cross-AZ calls. Find a great research below.

Creating diagrams from Text with the Help of GPT and Kroki 👷‍♂️

Recently I faced the necessity to draw a diagram and for the first time in my life I thought the task was too cumbersome to do it manually. So I decided to try to use ChatGPT to create a PlantUML diagram for me. The result wasn't great so I decided to search for tools to make it for me. And I found some, like ChatUML. And then I found this article, explaining how the whole idea could work. Haven't try the tool though, may be you would?

Bitemporal History

When we are talking about the historic events, you might want to consider the actual values used at a particular point in time, and what was the intended value. Martin Fowler introduces the term of Bitemporal History, which should depict those changes. However, even to himself it sounds a bit complicated and probably better replaced with just and Event Store :)

Bitemporal History
Bitemporal history has two dimensions: actual and record, allowing us to comprehend retroactive changes.
