New comment by LysPJ in "Generative art over the years"

LysPJ — Fri, 10 Apr 2026 11:48:56 +0000

If you consider the patterns in nature to be art (which I do!), you might enjoy the book "The Computational Beauty of Nature" by Gary William Flake. [0]

The subtitle is "Computer Explorations of Fractals, Chaos, Complex Systems, and Adaptation".

It's a wonderful book to own as a physical copy, and the contents are very inspiring for generative art.

Looks nice! Any chance of a side-by-side mode?

New comment by LysPJ in "Das Blinkenlights"

LysPJ — Wed, 15 Jan 2025 07:43:34 +0000

This story reminded me of the "BeBox" [0] PowerPC computer from the 1990's, which had Blinkenlights on its front bezel.

(It ran the very cool "BeOS" operating system[1], which was eventually ported to Mac, then x86.)

New comment by LysPJ in "C "clockwise/spiral" rule to understand declarations"

LysPJ — Wed, 01 Jan 2025 10:29:58 +0000

As a C programmer, declarations in Go appeared "backwards" to me when I first saw them.

IMO the Go syntax is a vast improvement as it's much simpler and avoids the clockwise/spiral issue: https://appliedgo.com/blog/go-declaration-syntax

Yes, this is indeed a different situation and my comment doesn't make that clear. Thank for pointing that out. I've made an edit.

> America/Nuuk does daylight savings at -01:00 (yes, with a negative)

Somewhat related: Europe/Dublin has a negative DST offset. Irish DST runs through the European winter (i.e. the opposite of the other European timezones).

(More details here: https://github.com/golang/go/issues/56743#issuecomment-13157... )

Edit: To be clear: the quote is referring to a negative DST start, rather than a negative DST offset.

New comment by LysPJ in "Apple's AirPods Pro hearing health features"

LysPJ — Tue, 22 Oct 2024 09:28:18 +0000

The music at many concerts and nightclubs is unfortunately loud enough to cause permanent hearing loss.

Ear plugs reduce the volume to a level where you can still hear the music, but the risk of long term damage is reduced. (You can get "musician's ear plugs" which attenuate all frequencies equally, so they don't make the music sound weird.)

LysPJ — Mon, 27 May 2024 09:56:14 +0000

But not over a cable.

Submarine cables are clearly marked on nautical charts, and even recreational boaters know not to anchor in those areas.

A professional trawler captain is not going to accidentally trawl over such an area.

Fees such as trading costs are a percentage of trading volume.

Therefore, the more money you are managing, the higher your trading costs. (i.e those costs are "fixed" but its a "fixed percentage" rather than a static number.)

New comment by LysPJ in "Endlessh-go: a Golang SSH tarpit that traps bots/scanners"

LysPJ — Thu, 28 Mar 2024 14:35:02 +0000

Endlessh periodically sends data so the read timeout won't trigger. Specifically, it draws out the crypto negotiation stage indefinitely by exploiting a feature of the SSH protocol.

(Of course, the bot author could detect that behaviour too.)

There's more info from the author of Endlessh: https://nullprogram.com/blog/2019/03/22/

New comment by LysPJ in "28-ton, 1.2-megawatt tidal kite is now exporting power to the grid"

LysPJ — Mon, 12 Feb 2024 10:30:06 +0000

For those wondering how they transfer the generated energy from the tidal kite to the shore:

> The turbine shaft turns the [onboard] generator which outputs electricity to the grid via a power cable in the tether and a seabed umbilical to the shore.

Thank you for taking the time to write such a clear and succinct readme.

I really liked the layout:

  - Why
  - How Lockbox helps
  - Main benefits
  - Drawbacks
  - How to run
  - Design philosophy

I wish more projects would follow this format :)

Out of interest, what did you use all that compute for?

LysPJ — Fri, 24 Nov 2023 11:58:44 +0000

I've been using GIMP for well over a decade, and the UI still deeply frustrating.

When I see what Blender has achieved over that time, I wish GIMP could have done the same.
