Hi! I'm Andy Walker. I'm a programmer living in Edinburgh, Scotland. In my spare time I'm interested in all things musical.

camtarn··on Proposed UK data centres could pay £100M in deposits for power demands
Title edited a bit to clarify that it's UK datacentres, and that it's specifically proposed ones - apparently the network is being swamped by speculative applications for grid connection and this might help weed out the non-serious candidates.

Original title was "Data centres could pay hundreds of millions in deposits for power demands"

camtarn··on Half-Baked Product
Sadly it's true. I've seen people just put the dishes in the dish rack and let the soap bubbles slide off them.
camtarn··on Electromagnetic Feedback: Making an electronic sound sculpture [video]
This one has a digital oscillator, but uses a coil of wire wrapped around a loudspeaker to introduce feedback into the audio path. This somehow gives a really nice 'roughness' to the sound.
camtarn··on Show HN: Triclock – A Triangular Clock
The Flux mode is really pretty!
camtarn··on Lessons learned shipping 500 units of my first hardware product
CRI of 80 is not great. From my reading, you want CRI 90 if you want light that's pleasant to exist in.
camtarn··on Native Linux VST plugin directory
Yabridge works, and it's frankly incredible that it works at all, but it has some trouble figuring out where I'm clicking on EZDrummer. It's gotten better in the latest version of Linux Mint but it's still a bit off.
camtarn··on Linux DAW: Help Linux musicians to quickly and easily find the tools they need
Huh, I had one of those Thinkpads and I had no idea that this was a thing!
camtarn··on Is The Line dead? [video]
As the headline is a question, the response is of course 'no', but it's a good video on the current state of it nonetheless.
camtarn··on Classical statues were not painted horribly
You can still sometimes find mushroom ketchup in UK supermarkets. It tastes a bit like Worcester sauce (spicy and 'brown' tasting), but milder as it has no anchovies in it.
camtarn··on Rats Play DOOM
That's the previous setup from four years ago, where the rats just run down a straight corridor.
camtarn··on Italy's longest-serving barista reflects on six decades behind the counter
I've had a coffee from a high end bean to cup machines, installed in a conference room at our vebdor's headquarters, which used fresh milk and made a better cappuccino than I've had from real humans at many chain coffee shops. They might be rare, but they're out there.
camtarn··on WinApps: Run Windows apps as if they were a part of the native Linux OS
Bit of a mixed bag for me. There are a lot of things that work remarkably well, but I have some issues with GPU performance (Cyberpunk 2077 just doesn't run well on Linux for me, despite running great on Windows on the same PC, and GPU-heavy apps like Insta360 Studio and Topaz Denoise run excruciatingly slow or not at all) and some things just don't work (my audio VST plugins work alright, albeit with some bugs about window position handling, but I can't get some of the licensing apps to work under WINE).
camtarn··on WinApps: Run Windows apps as if they were a part of the native Linux OS
Java edition can also use Realms. I'm playing on a realm using Linux Java edition and the official launcher now.
camtarn··on Poll HN: What operating system do you primarily develop on?
I'd prefer to run Linux, but one of my two primary dev targets requires a proprietary Windows IDE (Automation Studio by B&R). So running that on Windows then using WSL to develop for my Linux servers is the easy path.
camtarn··on Canva’s affinity strategy: Normies over power users
I really like Darktable, and it's my go to photo editor, but the user interface really isn't intuitive on first look compared to something like Lightroom. The design choice that editing modules should be ordered by their place in the pixel pipeline is logical and sometimes useful, but it ends up with a lot of the controls being in rather weird places. The customisable quick controls palette would help, if it weren't that simple things like cropping can't be added to it (at least, last time I investigated this - perhaps it's changed now?)
camtarn··on Carl Bohland's Auto Wash Bowl (2015)
Unfortunately, vintag.es does seem to have done some work here - while they copied the text, they also added several more images to the single image in the original post.
camtarn··on How bad can a $2.97 ADC be?
Hah, damn. We live in different worlds - in mine, 100K samples/sec is blazingly fast!

I'm currently working on a PLC program, replacing the PLC's basic cyclic input sampling (max 2K samples/sec) with a harder-to-use mechanism that lets you access the raw data off its 12-bit ADC at 10K samples/sec, which we consider unusually speedy.

camtarn··on I built physical album cards with NFC tags to teach my son music discovery
And they feel so futuristic!
camtarn··on Debugging Humidity: Lessons from deploying software in the physical world
Some of my code gets deployed to a PLC aboard a wave power generator hundreds of metres offshore, with a cellular link that might go down in a storm. If something gets unrecoverably wedged, retrieving the device starts at $10K to hire a ship.

I feel this blog post hard.

camtarn··on WinBoat: Windows apps on Linux with seamless integration
Yeah, it's pretty mind-blowing how well this works, even though the setup was a bit janky.

Sadly, after moving my music production setup from Windows to Linux, I'm locked out of some of my expensive sample libraries because while the plugins run fine, the licensing programs do not. Very frustrating.

camtarn··on Kicked from RubyGems, maintainers forge new home at Gem Cooperative
No, that serves a completely different purpose: I don't want to read through a very large discussion when this perfectly good article is here. Hence my point. You know this already, as you already change your wording depending on whether you're pointing to a duplicate article, or a valid article but where there's discussion elsewhere.

You could just admit that you made a trivial mistake on a post that's already fallen off the front page, you know. And then we wouldn't both have wasted our time.

camtarn··on Kicked from RubyGems, maintainers forge new home at Gem Cooperative
Not actually a dupe: unlike the story you linked, this article has a lot of background on the issue for those who don't follow Ruby community drama.
camtarn··on Retrocide Mono – A monospaced font with no decenders
No descenders - fine. But I find the lowercase L, and to a lesser extent the lowercase F, very unpleasant looking. Something to do with the overly intrusive and segmented curve.
camtarn··on Eternal Struggle
Hah! I was wondering if that was possible.
camtarn··on Bitwig Studio 6 details revealed, and editing gets a big boost
Huh, I use Bitwig and I had no idea it was Java! Very neat.
camtarn··on Selectramatronics [video]
A video about building an animatronic head, with the mouth movements done using a series of mouths on a servo-operated tilting/rotating ball, similar to the 'golf ball' mechanism used in an IBM Selectric electric typewriter.

Simultaneously extremely impressive and a bit cursed looking.

camtarn··on The Unforgotten
I read a lot of it, and I liked the writing, but it really is a very long article and eventually I gave up.
camtarn··on Altered states of consciousness induced by breathwork accompanied by music
They could have made their own, but it's really not that uncommon for music to slowly increase in tempo. Some styles of music use it more than others - for instance, ceremonial drumming might start out extremely slow and build to a frantic climax. But it's also fairly normal for musicians who are playing live, rather than to a click, to speed up when the music gets more intense.
camtarn··on Anna's Archive: An Update from the Team
I'm unable to resolve the domain on EE UK - looks like it's DNS blocked.

By comparison, on my work network (TalkTalk) I can resolve the domain but I get a connection reset from the site.

I think this might be the first time I've hit a DNS block. It feels rather eerie seeing people talking about a site that, from my point of view, doesn't even exist...

camtarn··on Show HN: Write lead sheets in a Markdown way and transpose in a second
Really cool project - I'm always a fan of things which make writing music in plain text easier.

It looks pretty bad on Android Chrome, sadly - when a tab block is attached to a word it seems to make a large gap between the first letter of the word and the rest of it. Hope it's an easy fix.
