In the [last post](Writing-Hello-world-from-scratch-Part-II.html), I connected a CPU to a UART to print "Hello, world over this serial link. Even if the endeavor is quite fun, it's not as impressive as writing it on a screen. To do so, we would need some sort of GPU.

Designing the ISA and the simulator is fine and dandy but it does not beat running a custom CPU on real hardware. Unfortunately, I don't have tens of thousands of euros to make a custom chip. The best I can do is to run it on an FPGA. An FPGA is a chip with a lot of logic gates that can be wired together to make any logic circuit. And our CPU is a logic circuit.

I have been interested in RISC-V for a while. I played a bit with RISC-V cores on FPGA but it is quite hard to find RISC-V cores on general-purpose computers. Fortunately, the company ClockworkPi is making the [DevTerm R-01](https://www.clockworkpi.com/product-page/devterm-kit-r01), a handheld computer with a RISC-V processor. The DevTerm R1 is a handheld computer featuring an RV64IMAFDCVU

The last time I went to Disneyland Paris, I used my smartphone to record the G-forces during some rides. I used an app called Physics Toolbox Accelerometer to record the acceleration to CSV files. Then, I made a small Python script to filter the data and plot it.

Vimscript is a well-designed language that is really tailored to extend Vim. Unfortunately, this language is not very powerful and quite clunky for general-purpose computing.

SSH is a nice technology. Not only can it be used to securely access another computer, but it can be used for other encrypted communication. Indeed, running a custom-made SSH server can be a way to expose nice services to the outside world. I want to give here some examples.

[Gemini](https://gemini.circumlunar.space/) is a nice alternative to the web. It is lighter than the web and very simple to host so I decided to host a copy of this blog as a Gemini server.

I recently found a very nice Git server named [Soft Serve](https://github.com/charmbracelet/soft-serve). This software offers both a git server to store repositories and a nice TUI front-end to list the stored repositories.

Multiples tools and components are used in this server to make it run and accessible from the internet. I want to describe them here to help me reconfigure a similar server in the future if needed. It might also be useful to anyone searching to run a similar web server themselves.

Algorithms made to find primes numbers are a good way to try out a new programming language. I include here some lists of numbers to compare the output of your programs.
