Some notes for future reference. First, run the tests with instrumentation enabled: > RUSTFLAGS="-C instrument-coverage" cargo test -p vparser Compiling vparser v0.1.0 (/home/hugo/src/git.sr.ht/~whynothugo/vdirsyncer-rs/vparser) Finished test [unoptimized + debuginfo] target(s) in 0.33s Running unittests src/lib.rs (target/debug/deps/vparser-5204a1fc06fb7f74) ... In some cases, you might need to merge multiple profraw files into a single one.https://whynothugo.nl/journal/2023/11/19/setting-up-an-alpine-linux-workstation/Sun, 19 Nov 2023 00:00:00 +0000https://whynothugo.nl/journal/2023/11/19/setting-up-an-alpine-linux-workstation/In the upcoming months I will travel to visit family and friends. I intend to work remotely during some of those weeks (and will take some other weeks off too). In preparation for this, I’ve set up a new1 ThinkPad T14s Gen 2i laptop that I’ll be using to work remotely. This article covers the steps that I take when setting up Alpine on this device. It is not intended to cover all possible installation options, but is a reference of my particular setup.https://whynothugo.nl/journal/2023/04/12/installing-postmarketos-on-a-oneplus-6-with-an-encrypted-filesystem/Wed, 12 Apr 2023 00:00:00 +0000https://whynothugo.nl/journal/2023/04/12/installing-postmarketos-on-a-oneplus-6-with-an-encrypted-filesystem/I’ve been experimenting with postmarketOS for a long time now. My long-term aspiration is to set up a phone that I can use as a daily driver. I need to overcome a lot of obstacles to achieve this. Today, my goal is to encrypt the main partition. So if I lose the phone, it doesn’t have all my messaging, email and credentials totally unencrypted. This is a hard requirement before moving forward with a lot of other things.https://whynothugo.nl/journal/2022/07/01/quick-and-simple-vms-with-qemu/Fri, 01 Jul 2022 00:00:00 +0000https://whynothugo.nl/journal/2022/07/01/quick-and-simple-vms-with-qemu/I don’t use VMs very often, so there’s no chance I can remember all the dozens of command line flags for qemu. I end up using virt-manager most of the time. It’s a GUI for managing QEMU (and other VM backends) and has dozens of checkboxes and buttons, which come in handy for really complex virtual hardware configurations where I’d need to know a dozen obscure command line flags to replicate the same results.
