From the archives of my blog but still very relevant: "pytz: The Fastest Footgun in the West", about why you probably shouldn't be using pytz:

And here are two pictures of the (adult male, I think) white-breasted nuthatch I got through the binoculars this morning.

I am much more confident in this identification.

They seem like a good match for these photos taken recently in NYC: https://urbanhawks.blogs.com/urban_hawks/2020/09/black-throated-green-warbler.html

Here are some pictures of the yellow-headed warbler I saw yesterday (managed to snap a few not great pictures through the binoculars this morning).

I think they are black-throated green warblers, despite the fact that none of the ones I saw were actually black-throated.

I'm thinking maybe this one could work? https://www.amazon.com/Canon-EF-S-55-250mm-F4-5-6-Cameras/dp/B078GQTWFX

I'm not entirely sure how to translate the focal lengths of the lenses into an equivalent of my experience using binoculars. If I could get photos that were somewhat equivalent to what I see when I use my Athlon Midas ED 8x42 binoculars, I'd be very happy.

#birding #photography

Any #birding folks have suggestions on how to take pictures of distant birds without spending a huge amount on it?

Not looking to become a professional wildlife photographer, just to have some identifiable pictures of the birds I've seen.

I have a Canon T4i, but I'd probably be as happy or happier to just get a little clip-on telephoto lens for my phone if a decent one exists.

I think the warbler may have been a black-throated warbler, but I couldn't get a picture of it and I don't remember if it had the black throat.

It's been hanging around here for the past few days, so I hopefully I can catch it again.

Lots of birds in my backyard this morning:

- Pileated woodpecker
- Downy woodpecker
- Bluejay
- White-breasted nuthatch (?)
- Warbler with yellow head and back
- Some sort of hawk

Head's up: Major breaking change coming to tzlocal, as in the next version it will return zoneinfo time zones: https://github.com/regebro/tzlocal/pull/92

Anyone using `tzlocal` should test against master. If your application doesn't break, you are probably using tzlocal wrong anyway.

#python

Now I need to get a telephoto lens for my phone or camera, because I keep wanting to take pictures of the stuff I see in the binoculars.

Just got a pair of nice 8x42 binoculars (Athlon Midas ED) and #protip: they make #birding so much better.

I don't know why no one thought to use these to look at birds before I came up with this wholly original idea.

Tip: On Cinnamon (and probably other Window managers and OSes), Alt + ~ is the same as Alt + Tab, but restricted to the currently active application (e.g. tab between Firefox windows).

Learned this from @LarryHastings@twitter.com last year and I've probably used it every day.

Having a pulse oximeter is kinda fun, though it's disconcerting that the pulse number starts blinking when it falls under 60 bpm, considering my normal HR is usually something around 50 bpm.

Context here is #python, if that wasn't clear.

If you wanted to write a conditional to check whether both a and b are None or neither are None, would you use comparison chaining for either condition, both conditions, or neither?

Chaining:

if a is b is None:
…
if a is not None is not b:
…

Non-chaining:

if a is None and b is None:
…
if a is not None and b is not None:
…

Been using an exercise ball for a chair for the past 3-4 business days and I can't tell if my back is sore because it's being exercised or because I have terrible posture.

Quite possibly both.

My brother apparently has a kidney stone, so of course I had to send him this: http://www.thomas-morris.uk/the-self-inflicted-lithotomy/

I should write a bot that cross-posts my tweets from my Twitter account, but also translates them into British English first.

A futuristic version of going to a new school where no one knows you and affecting an accent.
