Guy looks kinda like he’s wearing a jacket with a gap at the waist. That would totally not work. You can’t have a gap that lets air out. The Apollo suits were one piece designs; two piece with a hard shell locking waist ring came later.
We’re talking nowadays about compression suits that are only inflated around the head and maybe some upper body. Those would help a lot with mobility, but nothing like that has been deployed yet.
- Comment on Ex-Amazon VP explains why rich a-holes with helicopters and personal assistants don't get why you hate your commute 4 weeks ago:
With all of those, money is moving from the rich person to pilots, crew, maintenance staff, laborers, builders.
Gulfstream is an excellent example of this in action. Gulfstream jets can double the price over comparable products from brands like Bombardier or Cessna. And all of the crew, maintenance, training, and other operating costs can easily double as well. And, IMHO at least, there’s nothing about the Gulfstream aircraft that justifies this extravagant expense. As far as I can tell, the Gulfstream name is a machine that transfers money from unsuspecting and vain rich people straight to Gulfstream and a few aerospace workers.
- Comment on What are some of the things someone permanently relocating away from the US should be aware of? 4 weeks ago:
Even if you never plan to return, you are still (legally) on the hook to file a 1040-NR form with the IRS every year.
There’s a foreign earned income tax credit: this reduces your US tax bill by any income tax you paid to your residence country. For many expat working stiffs, this means they don’t have to pay anything to Uncle Sam, but they still have to file a tax return.
- Comment on what sources can I use to compare the armed forces of the world? Focus on America, Europe, Russia, Turkey, Japan, both Koreas 4 weeks ago:
Comparing national militaries is a complicated and tricky business. I would like to recommend Perun on YouTube. Usually pretty good defense economic analysis in digestible one-hour PowerPoint presentations. Some comparative material.
- Comment on YSK about Jury Nullification, if you're an American and you don't, look it up. 5 weeks ago:
We adopted a lot of the English legal system since a lot of the same courts were still operating before,
Except Louisiana. Louisiana is instead gifted with laws from Napoleonic France.

The statutory penalty in the US is on the order of $100,000 per infringement. “Statutory” means that the number is written into the law, and the aggrieved party doesn’t have to establish or prove actual losses.

Oh and would you just look at what’s happening to its input data, on those corporate social media sites… Imagine that, huh.
(In reality, peer review timelines being what they are, this trend is probably a year or two old.)

Ah, yeah okay. I forgot that Valve the privately held company doesn’t have to break out any numbers.

Did steam deck sales actually drop, as in the number of sold units went down? Or did the Steam Deck’s relative ranking on some leaderboard drop to a lower ranking?

802.11ax, clients just… (essentially) wait for a random amount of time, listen for a break in the signal, and take a leap of faith.
Ethernet originally worked the same way, back when it competed directly against token ring. Ethernet won by being as reliable in real world scenarios while being cheaper to build out. Gigabit Ethernet was the first standard that insisted on full duplex only.
Half duplex mode with the collision avoidance is still actively supported for 10/100, but it is becoming very hard to find an unswitched hub. So you may have to write up your own twisted pair cables.

E. coli is a coliform bacteria. That means it’s found in, you guessed it …shit. So E. coli is a great topic for a shitpost.
How the E coli gets from the shit to the meat is left as an exercise to the reader.

Why not just have the app dynamically generate the static with random numbers every time. There is no video file of white noise, and bonus the bumper intro is never exactly the same twice.
- Comment on Paralyzed Man Unable to Walk After Maker of His Powered Exoskeleton Tells Him It's Now Obsolete 5 months ago:
Here’s my guess. I don’t know anything about this particular device, but I have worked with medical devices.
A powered exo-skeleton sounds like it might be a class II medical device. Being a medical device, the OEM was required to produce a safety risk analysis per ISO 14971 in the EU and 21 CFR 820 in the US. I don’t know what all was listed, but probably one of the safety risks was thermal runaway from the (assumed) lithium ion batteries.
Lithium ion battery packs have a well known problem with occasionally overheating and catching fire. This famously delayed the launch of the 787 Dreamliner. This is also why you can’t put your phone or laptop battery into your checked luggage.
In the original risk analysis, there will be a number of mitigation steps identified for each hazard. For the lithium thermal runway, these probably include a mix of temperature monitoring, overheat shutdown, and passive design features in the battery pack itself to try to keep the impacts of over temperature and fire away from the patient.
So how does the price get to 100k? It could be some kind of unique design features that are now out of production and the original tooling is not available. The 100k cost is probably something like to redesign the production tooling, particularly if you have to remake injection molds.
You can’t just use any off the shelf battery pack, because that would invalidate the risk analysis. You’d need to redo the risk analysis, repeat at least some amount of validation testing, and possibly resubmit an application to the FDA.
TLDR: you can get some MEs and EEs together to solve this problem, but once they’re on the case, you can blow through 100k real fast.
