💡 Engineering/SSH Pro-Tip:

If you create an SSH key, use the Ed25519 algorithm rather than the RSA one.

This is the recommended algorithm for SSH keys nowadays.

If you still use RSA, be sure to be >= 4096-bit length

@dishantwt_ Nice! Good to hear.

Why does storing two-factor authentication codes in your password manager make sense?

Doesn't this invalidate the 2nd factor if the attacker gains access to your password manager?

This is the question I asked Security folks like Antti Kurittu and @myrcurial.

The tl;dr is "Yes, somehow, but this might be the best balance between security, usability, and mass adoption."

However, there is more to it ... I published their full answer in a blog post: https://t.co/gbHHR9W7WE

Was muss ich tun, um mein Team weiterzuentwickeln und auf das nächste Level zu heben? Ist das die Aufgabe meines Managers? Was ist mein Anteil? Weiß ich überhaupt, wohin ich mich entwickeln möchte?

@TweetsOfSumit Why limit yourself for your body/back/health to 500€?

I can't recommend the "HÅG CAPISCO 8106" enough. It forces you to sit correctly, and if you need it, you can use it as a stool or your standing desk—Pricy, but 100% worth it.

Hey, what is the best resource to get into Fuzzing? Mostly around using it, writing fuzz functions, for PHP, Python and Go.

@janvanthoor @EngKiosk Was sagst zu dem hier?

K8s is not a solution for scale. It’s a solution for resource utilization. Your backend scaling problems will be waiting for you also in containers.

In the GitHub repository https://t.co/rsSMzJJYdm, I prepared many examples for different databases in different programming languages.

Your database connection deserves a name ...

In my last twelve years, working mainly on scalability and reliability, I have been involved in many outages where overloaded databases were the root cause. Debugging these incidents is often not straightforward,
