I’m playing with ratterplatter again: It’s a toy that watches disk I/O and emulates the noise of a real hard disk. (Linux only.) It uses sound samples from one of my older disks.
I tried a different approach at estimating the disk activity and I think I finally got it right (after almost 10 years … 🤦).
Demo, booting a Windows 2000 VM: https://movq.de/v/1400544cc6/2kboot-ratterplatter-2.mp4
(For this purpose alone, I put a couple of mini speakers into my PC case, so that the noise comes from the right place: https://movq.de/v/a3b2dc0932/speakers.jpg)
The results aren’t too bad, but this thing can’t be super accurate due to the huge I/O caches that we have these days. For the video, I dropped the caches before booting Windows, otherwise you would have heard almost nothing.
FWIW, if you don’t know it yet, this is the equivalent for proper keyboard sound: https://github.com/zevv/bucklespring

I'm not much a fan of registry limit/offset paging. I think I prefer the cursor/count method. And starting at zero for first and max for latest.

Hmm so looking at the swagger of the registry spec client it seems to just take a “page”.. That seems worse than doing an offset. Lol.

Nvidia Linux GPU driver ported to Haiku
Nvidia releasing its Linux graphics driver as open source is already bearing fruit for alternative operating systems. As many people already knows, Nvidia published their kernel driver under MIT license: GitHub – NVIDIA/open-gpu-kernel-modules: NVIDIA Linux open GPU kernel module source (I will call it NVRM). This driver is very portable and its platform-independent part can be compiled for Haiku with minor effort (but it need to implement OS-specific … ⌘ Read more

Hmmm, when I
⤋ Read More
Ctrl+Left to jump a word left, I get 1;5D in my tt2 message text. My TERM is set to rxvt-unicode-256color. In tt, it works just fine. When I change to TERM=xterm-256color, it also works in tt2. I have to read up on that. Maybe even try to capture these sequences and rewrite them.
Well, some time ago I put this in my ~/.Xdefaults:
URxvt.keysym.Control-Up: \033[1;5A
URxvt.keysym.Control-Down: \033[1;5B
URxvt.keysym.Control-Left: \033[1;5D
URxvt.keysym.Control-Right: \033[1;5C
Probably to behave more like XTerm and fix a few other issues I had with other programs. But, it turns out, tcell expects the original sequence: https://github.com/gdamore/tcell/blob/main/terminfo/r/rxvt/term.go#L487
Hmm.
I saw 100% I/O wait in htop today but couldn’t find a process which actually does I/O. Turns out, I/O wait isn’t what it used to be anymore:
https://lwn.net/Articles/989272/
In my case, it was mpd which triggered this:
https://github.com/MusicPlayerDaemon/MPD/issues/2241
mpd doesn’t actually do anything, it just sits there and waits for events. To my understanding, this is similar to something blocking on read(). I’m not quite sure yet if displaying this as I/O wait (or “PSI some io”) is intentional or not – but it sure is confusing.

Dang it! I ran into import cycles with shared test utilities again. :-( Either I have to copy this function to set up an in-memory test storage across packages or I have to put it in the storage package itself and guard it with a build tag that is only used in tests (otherwise I end up with this function in my production binary as well). I don't like any of the alternatives. :-(

@lyse@lyse.isobeef.org OK. So how I have worked things like this out is to have the interface in the root package from the implementations. The interface doesn’t need to be tested since it’s just a contract. The implementations don’t need to import storage.Storage
- storage/ defines the
Storageinterface (no tests!)
- storage/sqlite for the sqlite implementation tests for sqlite directly
- storage/ram for the ram implementation and tests for RAM directly
- storage/sqlite for the sqlite implementation tests for sqlite directly
- controller/ can now import both storage and the implementation as needed.
So now I am guessing you wanted the RAM test for testing queries against sqlite and have it return some query response?
For that I usually would register a driver for SQL that emulates sqlite. Then it’s just a matter of passing the connection string to open the registered driver on setup.

Microsoft discovers massive malvertising campaign on GitHub
Like the other Chrome skins, Microsoft Edge is also moving to disable Manifest v2 extensions, restricting the effectiveness of ad blockers like uBlock Origin.

Blocking ads might be a necessary security practice, but why cry over spilled user data, am I right? Anyway, … ⌘ Read more

I have the feeling, that I have come to a dead end with my first version of the TwtxtReader. That’s why I’m stopping the project and starting again.
But of course, everyone is welcome to take a look at https://github.com/upputter/TwtxtReaderMK1
This document is the result of a series of discussions between Robert “Uncle Bob” Martin and John Ousterhout, held between September 2024 and February 2025. The text addresses three main topics: method length, comments, and Test Driven Development (TDD).

I got promoted today to try using Passkeys on Github.com. Fine 😅 I did that, but I discovered that when you use your Passkey to login, Chrome prompts you for your device’s password (i.e: The password you use to login to your macOS Desktop). Is that intentional? Kind of defeats the point no? I mean sure, now there’s no Password being transmitted, stored or presented to Github.com but still, all an attacker has to do is somehow be on my device and know my login password to my device right? Is that better or worse? 🤔
I’m continuing my tt rewrite in Go and quickly implemented a stack widget for tview. The builtin Pages is similar but way too complicated for my use case. I would have to specify a mandatory name and some additional options for each page. Also, it allows me to randomly jump around between pages using names, but only gives me direct access the first, however, not the last page. Weird. I don’t wanna remember names. All I really need is a classic stack. You open a new fullscreen dialog and maybe another one on top of that. Closing the upper most brings you back to the previous one and so on.
The very first dialog I added is viewing the raw message text. Unlike in @arne@uplegger.eu’s TwtxtReader, I’m not able to include the original timestamp, though. I don’t have it in its original form in the database. :-/
Next up is a URL view.
