I think the whole treesitter train passed me. Having separate ts major modes for every major mode, that are not derivates any more, makes configuration complex.

I'm not sure if the advantages of treesitter merit the complexity that was introduced into Emacs with this.

Some treesitter modes don't support certain features and I have constantly switch between modes.

Perhaps I'll remove treesitter completely for now as I don't see any gains for the moment.

What are your experiences? What features do you get out of a specific treesitter mode that are not available in non-treesitter modes?

I'm giving a public talk on "When Worlds Collide!" at 13:00 today (monday) at the Tūranga Library as part of the #ExSSV Extreme Solar Systems - come for the animations and rampant speculation, stay to read books!

Physicists have begun to explore the #proton as if it were a #subatomic planet.

Cutaway maps display newfound details of the particle’s interior.

The proton’s core features pressures more intense than in any other known form of #matter.

Halfway to the surface, clashing vortices of force push against each other.

And the “planet” as a whole is smaller than previous experiments had suggested.

I love this picture comparing different telescopes. Space telescopes are sexy - but the really big telescopes are down here. The Overwhelmingly Large Telescope is so big you might miss it: 100 meters across. Unfortunately the European Southern Observatory wimped out and decided to build a merely Extremely Large Telescope instead.

Radio telescopes are even bigger. The 305-meter dish at Arecibo is famous. In November 2020 scientist decided to shut it down after it was damaged by a hurricane and two earthquakes, and two important cables snapped. In December of that year more cables snapped and the support structure, antenna, and dome assembly all fell into the dish, destroying the whole thing.

Luckily in 2016 the Chinese had built an even larger radio dish in Guizhou: the Five-hundred-meter Aperture Spherical Telescope or FAST. It's the largest one shown here. But in Russia there's a radio telescope 576 meters across - not a dish, but a bunch of separate structures.

And then there's the xkcd cartoon....

I took this pic quite a few years ago at ESO's Paranal Observatory in #Chile. It shows the #MilkyWay arching over the entrance to the Residencia, the site's partially underground lodging and my home in the Atacama Desert for many hundreds of nights!

Right at the centre there's the Coalsack Nebula, known to the Mapuche people of south-central Chile as pozoko (water well) and to the Incas as yutu (a bird similar to a partridge).

@astro_jcm @kilian_muller Sure! thanks, Juan... okay, so the two amazing pieces of tech are (i) Adaptive Optics, which is where 'take the twinkle out of the star' by measuring the distortion put in by the Earth's turbulent atmosphere with a fast frame rate camera and removing it with a deformable mirror in the instrument. The other tech is that we use 'polarization' to see the disk. Star light is unpolarized, but star light bouncing from the disk becomes strongly polarised....

#Ireland just got their first test match win, in their 8th match! By way of comparison, when #India got their first win it was their 16th match. I therefore conclude that Ireland are twice as good at #cricket as India are. 🏏

The AI boom requires massive data centers that consume enormous amounts of water and energy.

Tech CEOs have plans for hundreds more hyperscale facilities in the coming years, but activists around the world are fighting back to protect their communities and force us to ask who really benefits from the future Silicon Valley is building.

Albuquerque, NM, has become the largest U.S. city to permanently make public transportation free for everyone. The city found that fares didn’t cover the administrative fees, so they actually save money by making public transportation free.

TOMORROW is the day... Rare Earth, BBC Radio 4's new climate and environment show, will start on 12-1pm on Friday January 19th, co-hosted by me and the ace Tom Heap. The first show is all about whether we can best help nature by just leaving it alone.

You can listen on the radio or on BBC Sounds: bbc.co.uk/programmes/m001vbsp

The first 18 segments of the primary mirror of ESO's Extremely Large #Telescope have arrived safely to #Chile !

Our engineers at Paranal Observatory checked that they hadn't suffered any damage during their 10000 km trip from France.

The ELT's 39-m mirror will be comprised of 798 of these segments, working together as a gigantic eye on the sky.

Astronomers measure the Universe's expansion rate and have found a discrepancy between the speed nearby versus the speed measured in the Cosmic Microwave Background. This is known as the Hubble Tension, and the search is on for anything that could explain it. One possible explanation is measurement error, which causes the Cepheid variables in galaxies to be too close together, obscuring results. New observations from JWST have removed this as an explanation.

Programming language clichés never die. That's perhaps why Jim Cownie had to debunk the "death" of Fortran:

cpufun.substack.com/p/is-fortr

and the XYplorer developer constantly needs to justify using a "toy" language like Basic for production code:
