When I complemented the proprietor of MyTeaPal on their 2024 Mei Tan Mao Feng they said, "For the two Mao Feng teas, the picking grade is lower than the other two teas, but having more leaves makes the flavor more rich. I can see why that's the case for a puerh drinker like you." Which, I dunno, is that a bit of a slam? Heh, well, it is true, I like richer flavored green teas...

@ellestad @tea this is why Yunnan greens are so good—because they're really bad at being "typical" high quality Chinese green teas

❓ Question for y'all software folks:

@CSLee and I are working on creating the Code Review Anxiety Toolkit based on her and @grimalkina's latest research: https://osf.io/preprints/psyarxiv/8k5a4.

The purpose of this resource will be to enable software developers to understand and mitigate their code review anxiety in a way that is supported by the empirical research.

@KFosterMarks I work with academic lab groups, and I'm guessing the format they'd find most useful would be text based workbooks, possibly with embedded videos—something a grad student or postdoc or RSE like me could use to facilitate a lab meeting on the topic

{geotargets} is officially part of Targetopia!

{geotargets} "is a {targets} workflow framework for geospatial data, focusing on the integration between {targets} and geospatial storage formats"

If that sounds interesting to you, please check out our GitHub repo and test it out!

Collaborating on code with someone on the other side of the globe is kind of magical. I open some issues or draft a PR, go to sleep, and it's like a magical elf works through the night to finish my ideas before I wake up. @njtierney

Any folks out there who use the {targets} package?

@njtierney and I have started working on the {geotargets} package, which hopefully will make it easier to use {targets} with packages like {terra}, {sf}, {stars}, etc. We would love your input! What are the current pain points? How have you solved them in your own work?

Akira Hojo’s latest blast email promotes a batch of green Tieguanyin, a genre I’m not very fond of: https://mailchi.mp/61b987a59f31/new-release-of-lan-yun-tie-guan-yin-from-anxi?e=e15ad97db8

But it answers a question I’ve long wondered about: why do green TGY leaves tend to have ragged edges?

It’s because enzymatic oxidation starts at the edges of the leaves; producers remove the edges (by machine) for uniform flavor/aroma.

He implies this is done only for high-grade TGY, but that isn’t my experience.

This morning I'm drinking Anji Bai Cha (安吉白茶) which, despite it's name, is a green tea not a white tea. It gets its name because the cultivar used to produce it is one of a handful of "albino" cultivars. This one is temperature sensitive and its chloroplasts lack the ability to make chlorophyll under a certain threshold temperature. Once it warms up later in the spring, the leaves turn green and look like any other tea plant.

LeafyEricScott,
@LeafyEricScott@fosstodon.org avatar

Because it isn't making chlorophyll, the amino acids and sugars sent to the young leaves accumulate instead of being used to build chlorophyll, giving them an extra umami flavor that makes this a prized green tea.

I had an amazing Mei Zhan black from Camelia Sinensis recently, and a mediocre (but much more affordable) version from Jesse's Teahouse. Who else carries good Mei Zhan? I'm looking to get some more on the higher quality end.

I want to get uncomfortably into drinking tea but I'm not sure where to start. Do I get an electric kettle or one of those things that automatically infuses at a certain temperature? What style tea?

I've been pondering this for years and still have yet to come up with answers.

@Aknorals Start with a simple cheap gaiwan and maybe an electric kettle. Get some nice oolong and enjoy the journey!

What's going on with {plotly}? The R package has 600+ open issues on GitHub, many of them bugs that were reported 5+ years ago and still aren't fixed. Just ran into two of those bugs trying to make a simple line + ribbon plot and only one has a workaround. How are they funded? Is anyone working on these bugs?

Awesome new feature in {patchwork} 1.2.0! You can now "collect" redundant axes the way you could collect identical legends previously! I used to do this manually a LOT so I'm super happy to see it as a feature!

There is a video showing how much various pets can grow. Showing how tiny grubs become huge beetles and little snakes become firehose friends...

But I think that ant colonies are one of the most impressive "growing" pets. Ants are small pets, but they can also be rather big pets.

The last tea of the year is 1970s Guangyungong pieces we bought from Yee On’s Hong Kong bricks-n-mortar shop in 2007.

The inky liquor is sweet and camphor, and the penetrating camphor of the huigan lasts and lasts.

"trophophoresy" is the term for when one animal carries another animal to a new location to farm it and harvest food from it.

but how do you say it??

tro fo foresy?
trop hop horesy?

It comes from trophobiosis. "tro fo bio sis" so probably the first one... but the second is more... evocative ...

LeafyEricScott,
@LeafyEricScott@fosstodon.org avatar

@futurebird tropho phoresy. Phoresy is animals hitching a ride on other animals. "Tropho-" is having to do with feeding. I had to stare at it for a while for that to pop out thought!

I've reviewed a paper for a big open access journal that charges almost USD 3000 in APC. The abstract had a typo in the first sentence which I didn't point out because I figured that such a big journal with such high article processing costs much surely hire a copy editor to proofread the final version. Apparently not. The typo is still there, right in the first sentence of the abstract.

Scientific publishing really is a big racket, isn't it?

LeafyEricScott,
@LeafyEricScott@fosstodon.org avatar

@eliocamp This is the worst! I once agreed to review an MDPI paper (never again) on the effects of cold stress on tea metabolites. The researchers used a weird cultivar that is known to respond to cold differently and then tried to extrapolate to all tea. I pointed out that this was not appropriate. In response the authors just removed all mention of the cultivar they used!! I told the editors I wouldn't review again until they addressed my concerns, so they just published it anyways 😖

@smach @rstats "Most important" is maybe a little misleading. More like "variables that vary the most". We show how biologically important variables don't always end up in the first few principal components in this paper: https://link.springer.com/article/10.1007/s00442-020-04848-w

@GetzlerChem @babelcarp @ellestad @tea thanks! I think I might have a paper about GABA oolong production—I'll have to (virtually) dig it out and see if there is any mention of what the actual chemisty is.

LeafyEricScott,
@LeafyEricScott@fosstodon.org avatar

@GetzlerChem @babelcarp @ellestad @tea didn't find the paper, but I'm guessing it's actually something biochemical and complicated (probably still involving redox reactions). GABA might be a natural product of tea, and perhaps it's production is upregulated under a purely nitrogen atmosphere for some reason. Tea leaves are still alive during this step oolong processing!
