Libuv and libev, two I/O libraries with similar names, recently had the privilege to use both libraries to write something. Now let's talk about my own subjective expression of common and different points.

The topic of high-performance network programming has been discussed. Asynchronous, asynchronous, or asynchronous. Whether it is epoll or kqueue, it is always indispensable to the asynchronous topic.

Libuv is asynchronous, and libev is synchronous multiplexing IO multiplexing.

Libev is a simple encapsulation of system I/O reuse. Basically, it solves the problem of different APIs between epoll and kqueuq. Ensure that programs written using livev's API can run on most *nix platforms. However, the disadvantages of libev are also obvious. Because it basically just encapsulates the Event Library, it is inconvenient to use. For example, accept(3) requires manual setnonblocking after connection. EAGAIN, EWOULDBLOCK, and EINTER need to be detected when reading from a socket. This is a

Mutt + isync mbsync + gmail + multiple accounts.

Mutt + isync multiple accounts Unfinished

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

[Remote Mail Servers] <= mbsync => [Local Mail Folders]

KeeAgent (for KeePass) on Bash on Windows / WSL (2)

Update (March 2023) (Last checked: Oktober 2024)

Side note: The latest edge build of KeeAgent plugin offers an option for creating a WSL compatible socket. This would be very handy. I already tried to use that socket, but the socket file is currently empty and ssh inside WSL 2 is unable to use it. This appears to be a very new, unreleased and unstable feature. I will follow the development of it and when it finally works (well, for me) I will update this HOWTO. But until then, please use the proven wsl-ssh-agent/npiperelay.exe approach below.

Thanks to the instructions for WSL 2 of the wsl-ssh-agent project, KeeAgent works great in WSL 2 now: https://github.com/rupor-github/wsl-ssh-agent#wsl-2-compatibility The approach uses minimal and well-maintained tools.

Keepass file format explained

Keepass file format explained

I’m currently working (I’m just at the beginning, and I’m quite slow) on a personal project that will use Keepass files (kdb and kdbx).
I tried to find some documentation about .kdb and .kdbx format, but I didn’t find anything, even in the Keepass official website. I you want to know how these file formats are structured, you must read Keepass’s source code. So I wrote this article that explains how Keepass file format are structured, maybe it will help someone.
