Computer

An overview of all the computing devices I have and use for work and play, including technical details about the individual setups.

Computer

The hardware I use has to be powerful but portable enough to not be a millstone round my neck. While a lot of the heavy lifting that I’m doing happens in the cloud these days, there are still plenty of tasks that can’t easily be outsourced and where raw computing power makes a big difference in overall velocity. Hence I’m always looking for ways to improve my setup to allow me to be portable yet have enough processing power in order to be independent from stable internet connectivity or somebody else’s computer.

f0g6, my Linux laptop

My main workstation is a Star Labs StarBook 14" Mk VI with 2 x 32 GB of Corsair Vengeance DDR4 RAM, an AMD Ryzen 7 5800U with integrated AMD Radeon graphics and a 2 TB hynix Gold PCIe NVMe (Gen3).

Software Management

I use portage for managing most software that I have installed. If I need something that is not available through the official sources, I either check the overlays or git clone the repo, build it myself, and link its binary manually to /usr/local/bin. Often times I install Rust tools using cargo, since it’s a pretty solid package manager. Go tools are a bit complicated to go install and keep up-to-date, but I have my .zshrc functions that help me with that. When I need Python or Ruby tools, I usually installed them through Portage because everything else is a PITA. For Node.js I use NPM, although I rarely use Node.js tools.

CLI / TUI

I have a separate list with most of the command-line tools that I used.

GUI

I don’t use many GUI applications. The main reason for me to use GUI tools is for creative work (like editing videos), and for that I still use a MacBook.

Other than that I use the following programs under Linux:

For the following applications I use dedicated VMs:

Engineering & Development

The command line is my go-to environment for everything related to engineering and development. I don’t use an IDE and instead do all my writing and development in NeoVim. Whenever I work with a service or a platform I check whether there is a TUI or at least CLI for it and, if there isn’t, I sometimes build one myself.

My tablet of choice is the 2023 Google Pixel Tablet 11" with 8 GB LPDDR5 RAM, a Google Tensor G2 and 128 GB UFS 3.1 storage. The tablet features 802.11 a/b/g/n/ac/ax WiFi 6 with MIMO and Bluetooth 5.2 and has a 27 Wh battery. At 493g it is nearly 50g heavier than Apple’s 11" M4 iPad Pro, but nearly 100g lighter than the 11" Samsung Galaxy Tab S9+. More importantly though, it’s the only tablet capable of running GrapheneOS.

cbrspc7

cbrspc7, my Linux workstation

After several years of the custom SFFPC dubbed cbrspc7 being my main workstation, I have recently replaced it with a more portable Linux laptop. cbrspc7 is now serving as a secondary workstation. It is a custom built Xtia Xproto-N frame running Gentoo Linux.

The initial build had the Lian Li Galahad 240 AIO for cooling the CPU. However, after the Galahad died roughly ~11 months later, I replaced it with a Noctua NH-C14S air cooler.

The PC runs the latest available kernel supported by ZFS, with encrypted ZFS in mirror-mode across two 1TB NVMe M.2 SSDs. I use Sway – a Wayland window manager – to mainly have multiple instances of Alacritty, ungoogled Chromium, and Firefox on a 4K display.

d4lt4, a 2018 15-inch MacBook Pro

I still own a beaten up 2018 15" MacBook Pro with 32GB DDR4 RAM, an Intel UHD 630 and an additional AMD Radeon Pro 560X 4GB on-board graphics card. It’s one of those MacBooks without a physical escape key. These days I rarely use it anymore.

The MacBook runs the latest macOS release. Security, privacy and the overall dissatisfaction with Apple hardware in general is what had pushed me to invest effort into switching from macOS back to Linux. These days I’m running solely Linux on a day to day basis.

Software Management

I use brew for managing most of the software that’s running on my MacBook.

CLI / TUI

On macOS I have a tmux session that’s constantly running inside a single instance/window of Alacritty. That’s due to Alacritty not really supporting multiple windows/tabs/panes on macOS.

The shell that I used even before macOS made it the default was and still is Zsh, with Oh My Zsh installed and my own carefully crafted .zshrc

I use to keep my .zshrc functional on both, Linux and macOS, so that I can easily sync my dotfiles between machines.

GUI

For the most parts I’m using the Mac when I need to do something that requires a graphical application like an image or video editing software. I’m looking forward to move these tasks to my Linux workstation as well, but so far it has been more easier to continue using them on macOS. I will continue doing so up until the point when the hardware might fail.

However, besides of the crude command line interface I use LaunchBar, because it lets me keep my hands on the keyboard while performing UI-related actions and tasks. LaunchBar brings a large set of functions and allows for easy extensibility. Other UI programs and little helpers that I use include:

Creative Work

I stay miles away from Adobe software and successfully got rid of the very last Adobe program I was using, which was Lightroom Classic. For the little creative work that I’m doing, I’m using the following programs:

I really don’t do much creative work, though. It’s more of a hobby. The reason I keep things like Pixelmator around is for the times when people send me PSDs or when I really do need to draw a few things on my own.

The case is a custom designed, 3D printed enclosure that was built with portability in mind. h4nk4 has no HIDs nor a GPU – the Ryzen is not an APU – and is therefor configured to use a LUKS encryption key on a USB stick, that can simply be unplugged in order to make the device useless.

Unlike the majority of reviews online by people who struggled to properly set up and run the Linksys, I have experienced no issues with it whatsoever. That said, I’m only running the 5 GHz band for WiFi and all devices that have a NIC are using a wired connection.
