There is nothing silent about this Sunday morning. The birds in the little wood in our backyard are VERY LOUD, and I enjoy it thoroughly!

The characteristic song of the White-Throated Sparrow dominates but a lot of other species can be heard (and observed).

  • Dark-Eyed Junco
  • Northern Cardinal
  • Pine Siskin
  • Tufted Titmouse
  • American Robin
  • European Starling
  • Purple Finch
  • American Goldfinch
  • Mourning Dove
  • Blue Jay
  • Northern Flicker

@nedbat this is great! It can be useful to find functions or classes that are not used after a refactoring.

I like to use https://pythex.org/ to develop and test my regex patterns. The included cheat sheet is also quite useful.

Time to get ready for the solar eclipse on Monday (yes, I know, I'm last minute). I will not be setting up any photo equipment. I want to simply enjoy the experience and not have to stress about exposure settings, etc.

I am 3D printing a holder to mount a solar filter on my partner's 85mm bird spotting scope which I will be installing on my EQ mount for tracking the sun movement. Otherwise, a lawn chair and eclipse shades. That's all.

The forecast looks good so fingers crossed!

jdlbt,
@jdlbt@techhub.social avatar

Part 1/2 - the rear flange - is printed and the fit with the scope is perfect! Snug but not too tight. The rubberised finish on the scope helps.

The front plate which will keep the filter foil in "sandwich" is currently printing. About 2h hours to go.

Part 2/2 is done printing. A few minutes of assembly and the filter is ready to use.

And in case you wonder, yes the wrinkles are on purpose. Baader, the film manufacturer recommends that the film not be taut.

And idem for the good old Monarchs.

@jdlbt@techhub.social avatar

Test run this afternoon, all systems are GO for tomorrow, including the weather!

The Baaded AstroSolar filter I had was too bright to be comfortable to the eye but fortunately my astronomy club had leftovers of the film used for the eclipse shades. A quick filter swap and now it is much more comfortable for extended viewing.

We took the opportunity to watch the sun spots, including two large ones next to each other that look like eggs in a pan.

I just saw an advertisement for Formula E team that says again and again how they how they show, quote,
"commitment to environmental sustainability and raising awareness of the fight against climate change."

And they are doing that by putting the climate stripes (the ones about rising temps) on their car.

I'd say the best thing they could do to fight against climate change is stop pointlessly riding in a circle and use resources and electricity for nothing.

Just sayin'

Two recent changes I've made to the Python docs I'm happy about:

📘 Links are underlined, which is important for accessibility.
https://adrianroselli.com/2016/06/on-link-underlines.html

📗 The dated Lucida Grande was the Mac system font a decade ago and used for the docs on Mac (and only Mac). We now use the system font stack, to get a similar result to Linux, Windows, Android and iOS.
https://systemfontstack.com

Before: https://docs.python.org/3.10/tutorial/index.html

After: https://docs.python.org/3.12/tutorial/index.html

The Python tutorial, shown on macOS with Arial and prose, non-navigational links are underlined.

jdlbt,
@jdlbt@techhub.social avatar

@hugovk This is great, thank you!

Any chance these changes can be retroactively applied to older Python versions docs? When developing libraries, we often have to look specifically for these notes in the docs of multiple Python versions, e.g 3.9 - 3.12.

jdlbt, to accessibility
@jdlbt@techhub.social avatar

What's the best way to share code snippets on Mastodon that considers accessibility?

Without the ability to format toots (e.g. markdown), it seems like code to image generators are the way to go. But what about the alt-text? Should I just copy the code as-is in the alt-text?

So far the interactive version of the Rust Book is very clear. https://rust-book.cs.brown.edu/title-page.html

I'm still just in chapter 4 of the Rust Book but I wanted to practice what I learned so far so I made my first Rust application, a simple dice roller.

I had to search a bit to use the Clap crate for CLI arg parsing.

In addition to the bazillionty things I said I would do this week, I need to get my astrobiology students to pick their final project topics: they have to evaluate a work of scifi on the plausibility of its aliens using what they learned from my astrobiology course.

I've asked here before, but I'll ask again: what are some scifi works that have really great aliens and/or alien worlds?

My list so far:

A Desolation Called Peace - Arkady Martine

greatgodoffire, to astrophotography

I am interested in but my current equipment is quite limited; I have my dad's Canon EOS 5D Mark III (which is defintively a good camera) with a 135mm camera lens as well as a 90/1000 Omegon achromatic refractor telescope on a quite flimsy equatorial mount without goto or automated tracking.
I am considering getting a better telescope but I have no idea where to start. Are there some telescopes you can recommend I won't have to spend a fortune on?

jdlbt,
@jdlbt@techhub.social avatar

@greatgodoffire 135mm is a good focal length to get started in AP. It is more forgiving and allows you to do reasonably long exposures without autoguiding. If your current EQ mount can track on the RA axis, I'd recommend you give this a try before buying anything.

In AP, a good goto mount is probably the most important piece of gear to buy. With focal lengths ~200mm and above, autoguiding is required to get long sub-exposures without star trailing, and a goto mount is required for autoguiding. It also allows dithering (move the framing just a little bit between exposures) which helps significantly reduce fixed pattern noise from the camera sensor.

Once you have a good mount, you can consider APO scopes in the 250-400mm focal length range like the WO Redcat 51 or the Askar FRA400 (I have the FRA400 and it is AMAZING).
