trothamel··on Supreme Court rules to uphold TikTok ban, setting stage for shutdown
There is a rule of law issue here.

Say, for example, congress passes and the president signs a law that says that product sponsorships in videos need to be disclosed. If a US company (or a European, Australian, Japanese, etc) country violates that law, we're pretty sure that a judgement against them can change that behavior.

China? Not so much, given their history.

trothamel··on Blue Origin reaches orbit on first flight of its titanic New Glenn rocket
It also helps that they fairly routinely land boosters (with New Shepard), which means they've likely worked out the 'landing' part.

Now to see if they can solve the reentry problem.

trothamel··on Giga Is ITU and UNICEF's School Connectivity Project
They want to spend $429B to link up 6M schools. That's a cost of $71K a school.

It looks like Starlink is $17,000 for ten years of service, so even if you were to add a few thousand dollars for installation, there's a lot of overhead there.

It does strike me that a top-down approach seems more costly than a model that allows schools to get grants.

trothamel··on NASA is selling a brand-new Moon rover: Never used, one previous owner
In 1993, the price of a non-functional lunar rover was $68,500.

That's how much Richard Garriott (son of astronaut Owen Garriott, creator of the Ultima game series, and after that, private astronaut that spent 12 days at the ISS) spent to purchase the rights to Lunokhod 2 and the Luna 21 lander.

trothamel··on What, Me Worry? The Art and Humor of Mad Magazine
I saw this exhibition a few weeks ago.

My generally feeling was it didn't work that well, mostly because the MAD stuff is very dense, more dense than you'd expect from painting in an art gallery. A lot of it is also very dependent on pop culture that has changed in the interim.

Probably the two best pieces were the direct parodies of the Rockwell paintings, exhibited next to the pieces they parodied.

The Rockwell museum also made an effort to exhibit some of Rockwell's most humorous pieces in some of the side galleries, which worked well here.

trothamel··on NASA announces Boeing Starliner crew will return on SpaceX Crew-9
> correctly describes a joy-ride of the gods.

Pretty much this. Polaris Dawn is happening because Jared Isaacman wanted it to. And my point is that SpaceX has gotten the price down to the point where he was able to afford multiple trips.

trothamel··on NASA announces Boeing Starliner crew will return on SpaceX Crew-9
Given that SpaceX is about to launch four people on what is more-or-less a joyride (Polaris Dawn), it's really only the government and boeing that seem to be having problems.
trothamel··on NASA acknowledges it cannot quantify risk of Starliner propulsion issues
As I mention in a sibling post, Soyuz might have more launches, but it also has way more launch failures.
trothamel··on NASA acknowledges it cannot quantify risk of Starliner propulsion issues
Thanks for running the numbers, which I think prove that it's impossible to say that Soyuz is more reliable than Falcon, even if you count AMOS-1 (which feels like it should be counted) and CRS-1 (which I don't).
trothamel··on NASA acknowledges it cannot quantify risk of Starliner propulsion issues
Looking at the three most recent Soyuz variants:

Soyuz-U had 765 successes in 786 flights. (97.3%) Soyuz-FG had 69 successes in 70 flights (98.5%) Soyuz-2 has 160 successes in 166 flights (96.3%)

Falcon 9 has 362 successes in 365 flights. (99.1%). That includes the partial failure of the CRS-1 mission, which successfully delivered CRS-1 to the space station but released secondary payloads into a lower than expected orbit. It does't include the AMOS-6 fire, which would bring Falcon 9 down 98.9%.

Falcon 9 is more reliable than Soyuz.

trothamel··on No tax on tips: Why politicians love it, and economists don't
Either you or the company pays tax on the tip portion of the reimbursement.
trothamel··on No tax on tips: Why politicians love it, and economists don't
Disallowing tips from corporations seems like it could go a long way to curbing abuses.
trothamel··on Microsoft says 8.5M Windows devices were affected by CrowdStrike outage
No.

Software freedom 0 is that you should be free to run the program as you wish, for any purpose.

If that means loading your system up with third-party crapware, that's on you, not them. That doesn't mean Microsoft shouldn't work on making it easy to recover a system, if they can, but preventing you from running software would make the cure worse that the disease.

trothamel··on The Titan Submersible Disaster. The Inside Story Is More Disturbing
Their attitude for crewed flights is to put pictures of the astronauts on every work order generated for the mission.
trothamel··on How bad are satellite megaconstellations for astronomy?
30 years ago, it was possible to be lost - not because you wanted to be, but because you had no way of figuring out where we are. GPS and other GNSS networks have solved that problem.

It used to be possible to not have high-speed internet, and now high-speed Internet is available everywhere in the world that has an amenable government.

Right now, it's possible to be in a location where it's impossible to call for help. In a few years, when LTE-in-space is available and the 911 mandate applies to it, anyone with a charged phone will be able to get contact.

SpaceX has been working to mitigate how its satellites affect astronomy - see https://api.starlink.com/public-files/BrightnessMitigationBe... and https://new.nsf.gov/news/statement-nsf-astronomy-coordinatio... .

But fundamentally, to limit space to astronomy will be to limit the benefits it can give all mankind. a

trothamel··on Boeing Starliner's first crewed mission scrubbed
Dissimilar Redundancy. Say the Falcon 9 suffers an in-flight failure. The last time that happened, there was a stand-down for quite some time, and I suspect that there would be a similar amount of time before people could be flown on it, even if I'd think Starlinks could resume right away.

Starliner/Atlas wouldn't be affected, and so ensure the US and our allies have access to the station without getting Russia involved.

trothamel··on 00Key a 75% Keyboard
I bought the Keychron V6 a couple weeks ago, and I'm loving it. It only has 4 extra keys, but it's nice to have a single button that builds and flashes a device, rather than a multi-key combo.

Also runs QMK/Via, which means I can reprogram those buttons on device, rather than having to make the apps correspond to the keyboard.

trothamel··on YouTube's Legal Team sent me a letter [video]
This bans the use of alternative youtube clients, but not the creation of such clients.
trothamel··on Keep Out – WebGL Game
I'm not as huge fan of the controls. I have five fingers on my left hand, and there are six buttons there, so I'm constantly moving them around, while my right hand doesn't do much. Maybe figure out a way to use both hands?
trothamel··on The great commercial takeover of low Earth orbit
While the wet-tank concept has been explored since Skylab, that's a lot of work to do before your station becomes habitable - and where do you stay while doing the work?

Launching inflatable stations inside the cargo area of Starship seems to be a much better approach, as all the fitting-out can be done on Earth, so the station is immediately inhabitable.

trothamel··on NPR suspends veteran editor as it grapples with his public criticism
This. As someone who's probably center-right, I used to listen to NPR a lot because they'd often offer new perspectives on things. But now, they offer the same perspective, over and over and over again - and so I usually turn them off.
trothamel··on NASA tries to jog Voyager 1's memory from 15B miles away
I believe there is a way of pushing the reset button. What you do is feed the bits coming out of the radio receiver into a shift register, and when they match a particular pattern, a reset is triggered.

(It wouldn't surprise me if they could shift between primary and backup computers this way as well.)

One thing that does have great backup time is the RAM, which IIRC is powered by a dedicated power line coming right off the RTGs.

trothamel··on NASA tries to jog Voyager 1's memory from 15B miles away
It's not one month. Voyager 1 is 22h, 33m, 15s away, so it's about a 2 day round trip.

In the US, retirement savings can be tax advantaged, so you'd need to take a look at that and compare the penalties to the interest.

That's a two-edged sword. There are consequences to what the school says and does, and they _also_ have to accept the consequences.

But also having a history of announcements that take longer than expected, and come true. (Reusable rockets come to mind.)
