⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon
with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.
Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple
) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic
module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.
Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.
Older Keychron keyboards (those not based on QMK) use the hid_apple
driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

In this tutorial, I will be going over to how to deploy a Javascript app from start to finish using AWS and EC2. Recently, my partner Tu and I launched our app AlgoAcademy (a resource for reviewing algorithms and data structures) and we wanted to share with other developers some of the lessons we learned along the way.
Following this tutorial, you will have an application that has:
- A React frontend, Express backend
- An AWS EC2 server configured to host your application
- SSL-certification with Certbot
- A custom domain name

Here I will show you how to create a bar very similar to the nicklist bar, but instead of showing nickname, it will show znc commands, whenever you click on a command, weechat will send a "help the_command_you_just_clicked" and insert the name of the command in the input bar, then enter any arguments required to the command and press enter.
You will need the following script
