I figured as much given they were comparing it to the Purosangue. Unfortunate that the proportions just make it, idk, horizontally squat looking.

I’m a big fan of the interior & Ive design (and am not always a fan if his). The exterior is pretty cool from the front and back … but from the side and at angles it just doesn’t register as Ferrari at ALL. Seems to scream for a longer wheelbase but that’s not the whole issue. It just looks very mid-market from those angles.

You have to look at it now like cryptocurrency “market cap” numbers. It’s more of a marketing tool than anything. This is just another honking whirlygig to bolt onto the SpaceX IPO to try and generate exit liquidity

Last time I flew my family was very early to the gate; it was me, my wife, my 5 and 3 year old girls, and a very elderly lady in a wheelchair who was blasting Kendrick Lamar’s “Not Like Us” from her phone speakers.

Docs. Load-bearing implicit authority. Attribution of sales. Implicit assumptions about humor / topicality in group chats. Office kitchen standards & practices.

It’s up to the CEO to fix all of it, directly or indirectly. Except perhaps the chat one. You need someone with community-manager DNA and a light touch, lest the CEO come off as control freak. (Which is ironic bc they have to be one in many areas but this is one where it will alienate people)

I guess you live in a different population than me, where all the physical and occupational therapists are out of work

It doesn’t really affect hypertrophy but it matters because imbalances will get you weird injuries and/or mobility restrictions in the long term.

They are good summaries. They’ve essentially replaced low- to mid- depth magaize articles, and some of the high depending on the topic

New comment by jraines in "How America's "truck-driver shortage""

jraines — Sat, 06 Dec 2025 12:46:30 +0000

A relative ran a trucking operation for a few years and now says he’s significantly more wary of any trucks on the road.

At the same time, he says that it’s a miserable business because you’re constantly getting sued (at a level markedly higher than the admittedly poor driver performance)

This PBS Spacetime video pours some cold water on the black holes as dark matter hypothesis:

https://youtu.be/qy8MdewY_TY?si=9jc_a7IAm4qrhfNX

It’s 4 years old; I don’t know if this JWST finding changes anything. I do know we have finally found some (one?) intermediate-mass black holes in the interim, but I don’t know if that changes it either.

The possibility it leaves open for “Planck relics” is interestingly exotic

the extra mass is converted into energy in the form of gravitational waves (maybe other forms too idk but this is part of it)

The article is wrong. That’s when they changed it for fly/free.

Here is the 92 backstroke final. The announcers mention the rule: https://youtu.be/FTfTyzkSzQs?si=E82rvKql-w9vuwSf

I tried to find 96 and cannot but it was the same.

Here is the butterfly performance in 96 that ultimately triggered them to chamge it for fly/free: https://youtu.be/Zp2NTFjeXQQ?si=e_E-D1ZAvzNmjACe

the backstroke rule change was circa 1988. They changed butterfly (and I suppose freestyle) after the 96 Olympics when Dennis Pankratov won both butterflies with this technique. Interestingly, the backstroke innovator who probably triggered the earlier rule change got beat in the final by someone not using it (Berkhoff in 88, silver)

The latest rule change in this area was banning dolphin kicks on your back on the breast-to-free exchange in IM. Ryan Lochte triggered that one.

jraines — Mon, 09 Jun 2025 16:08:42 +0000

The benefit of AI as a feature in calorie counting apps is great. But you have to track stuff manually for a while to realize the benefit. Specifically: using AI for restaurant meals is a convenient starting point, from which you use your hard-won feel for weight & caloric density of things to tweak the first pass to something closer to the mark.

As of now I would not at all trust a fully AI calorie counting app

Most Senators are not well known nationally (sadly) unless they’ve either:

- done a non-negligible Presidential campaign

- been born from a famous family

- the press either love them or love to hate them

- have a leadership position and/or are conspicuously ancient

Relentless self-promotors are a superset of 3, the ones who succeed

Unfortunately being sensible, cooperative, or good with policy isn’t on the list

It can occasionally work for state Governors
