L2 as related to space telescopes was a new term to me, and turned out to be utterly fascinating. The Webb orbits the sun and periodically boosts velocity using Earth's gravity:

> The James Webb Space Telescope is not in orbit around the Earth, like the Hubble Space Telescope is – it actually orbits the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2.

The wiki on lagrangian points also has a bunch of useful info on this stuff. Gravity is absolutely incredible

Okay, I'll help him humble brag:

Bryan is in his last year of high school.

Keep building!

This is incredible work for anyone, let alone a high schooler. Seriously impressive!

I hope this turns into something I can buy (maybe a diy kit), in the future!

"The analysis revealed that both the CVR and FDR data were not recording during the four minutes leading up to the aircraft's collision"

How does this even happen where two systems would stop recording data. This story seems to get weirder and weirder. I'd always been under the impression that black boxes were really highly secure and extremely rigorously developed to specifically prevent data loss in situations like this.

Bad enough for the accident to occur, but to not have accurate telemetry and recorded data from the onboard systems is definitely going to make an already hard investigation very much harder

Again, we don’t know that. It could easily be that the adaptations needed to operate well at night (in addition to during the day) just aren’t worth the energetic cost or they entail a large morphological compromise. The thing about evolution is it doesn’t give you its reasons.
chuckwfinley · a year ago
Exactly, evolution also will leave things at "good enough for function". It may well be that our sleep cycle so happened to level off at "good enough" considering our other evolutionary constraints.

Definitely an area of study that seems interesting to me.

Trump also wanted to rename the Gulf of Mexico to Gulf of America. This is all about vanity, not about minerals, economy, security etc.

In his press conference Trump mentioned the world map multiple times. Trump may well be forming his annexation ambitions based on what the map would look like after the annexation. Well, the world map looks very different based on what kind of projection you use. In the Mercator projection Greenland looks big. Bigger than the US, in fact. This may be what is attracting Trump, as it looks like a lot of real estate. Tobler hyperelliptical projection on the other hand makes Greenland look small. Someone should show Trump this projection and it may very well cause him to lose interest, and we can sidestep a dispute with Denmark and Europe.

chuckwfinley · a year ago
Ha! I said this the other day to a friend as well. The 'typical' (Mercator) view has Greenland looking nearly as big as the continent of Africa. Reality is that it's about 1/4 the size of the mainland US. Still a lot of land but not as big as a lot of people seem to assume.

I honestly have no idea how basic math (sphere to flat projection) escapes people.

They apparently paid $20 million for the use of Einstein's image: https://www.bloomberg.com/news/articles/2024-03-27/salesforc...
chuckwfinley · a year ago
TIL that the likeness of Einstein was licensed. Proceeds go to the Hebrew University of Jerusalem, which is fitting considering his support and investment:

"Albert Einstein is one of the founders of the Hebrew University of Jerusalem. To him, the university represented a combination of the commitment to his Jewish identity and his belief in the universal values of the pursuit of truth and respect for every human being."

> can't imagine a mountain biker wearing a bunch of bulky padding

XC or recreational trail riding, probably not, but if you're into enduro, freeride or downhill, you can (should) already be wearing a lot of really bulky gear. Heavy duty boots with toe protection, pads for your knees, hips, elbows, gloves, spine and chest protectors, neck braces, full face helmets with MIPS

I believe some kind of airbag solution could actually be really helpful, but here's the thing about falls in MTB: they happen quite often and they're usually harmless, sometimes you even toss the bike on purpose when you realize you've messed up or miscalculated a feature.

And you probably don't want to replace an expensive gas [generator] cartridge or suffer burns or just have to endure loud pops every time you make a mistake.

chuckwfinley · a year ago
Yep definitely agreed on the existing padding, it just seems that, given the article, more is needed in some fashion.

This is interesting and I don't doubt the problem exists, but just considering the physics of a person riding a bike, it seems tough to envision an effective safety system.

Maybe expanded use of those "bike airbag helmets"? I can't imagine a mountain biker wearing a bunch of bulky padding and still being able to participate in the sport.

I mean, if they add a code editor, terminal, and browser to steam, that should be it (at least for me). I guess I could just use a cloud IDE.

There really is absolutely nothing about Windows I use other than clicking games on Steam.

Gamers keep Windows relevant and fresh. Once we’re gone, it really will be a legacy OS that people still use because their printer won’t work with shit else.

chuckwfinley · a year ago
As far as I know, you can drop back to desktop mode on SteamOS and be on your way.
