Quick Tips for Fast Code on the JVM

I was talking to a coworker recently about general techniques that almost always form the core of any effort to write very fast, down-to-the-metal hot path code on the JVM, and they pointed out that there really isn't a particularly good place to go for this information. It occurred to me that, really, I had more or less picked up all of it by word of mouth and experience, and there just aren't any good reference sources on the topic. So… here's my word of mouth.

This is by no means a comprehensive gist. It's also important to understand that the techniques that I outline in here are not 100% absolute either. Performance on the JVM is an incredibly complicated subject, and while there are rules that almost always hold true, the "almost" remains very salient. Also, for many or even most applications, there will be other techniques that I'm not mentioning which will have a greater impact. JMH, Java Flight Recorder, and a good profiler are your very best friend! Mea

Consensus systems - Zookeeper, etcd, consul - what is that?

I for some time had a semi-finished Erklärbärartikel on "consensus
systems - Zookeeper, etcd, consul" through my mind, because every time I
roll my toenails when someone classifies them as KV-storages.

Generating Authy passwords on other authenticators

---

Update 04.04.2020: Please take a look at many of the forks of this gist or comments, where people have updated or improved upon the code. I have not needed this in a long time, which is why the original document has not been updated and the code probably does not work. Stay secure and only copy and paste code that you trust.

There is an increasing count of applications which use Authy for two-factor authentication. However many users who aren't using Authy, have their own authenticator setup up already and do not wish to use two applications for generating passwords.

Since I use 1Password for all of my password storing/generating needs, I was looking for a solution to use Authy passwords on that. I couldn't find any completely working solutions, however I stumbled upon a gist by Brian Hartvigsen. His post had a neat code with it to generate QR codes (beware, thro
