Turn auto-exposure off, set absolute exposure to a low level and use gain to compensate for low light if needed. E.g.:
v4l2-ctl -d /dev/video2 -c exposure_absolute=400
v4l2-ctl -d /dev/video2 -c gain=110
# check with
v4l2-ctl -d /dev/video2 -L

Since it is not possible to rely on the encryption that is provided for us in our daily applications (email, chat, etc), so, I decide to create this method as an alternative to quickly send sensitive data through current chat applications, email, etc.
Using openssl in both sides (the sender and the receiver) is possible to exchange encrypted messages using our preffered chat application. In this process, I tied receiver's github account with his SSH public key, that way we can believe a little bit more if the receiver is who we think he is.

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
This is the setup that I use for mutt, I have two google domain account (read as gmail) and an institution where I work and study account. This means I have two gmail accounts and one outlook 365 account that i want to sync and read via mutt.
I want to store all my email locally as I travel a lot and will be in countries without easy internet access. For this I use mbsync (iSync). As it can handle multiple account types easily and efficently.
The setup works this way
