Allowed the whole time in all California jurisdictions, or allowed now (after lawsuits)?
Wasn't the Hamilton Standard suit for EVAs? I don't think the ones they wore today are comparable, they're more of a replacement for the "pumpkin suits"
Oh that would be sacrilege and misappropriation of a religious symbol, jedi would be boycotting in their droves outside all showing going something like this: https://www.youtube.com/watch?v=qsvbYKr19ng

The government can't really measure the harm caused by interfering with otherwise lawful religious practice. You and I can have our opinions but legally it isn't within the power of the government to do so. How could it? What if the interference delays a child's baptism and the child dies during the delay. For some religions this may be an irreparable eternal harm.

From the dissent:

"As a general matter, the “government may not use religion as a basis of classification for the imposition of duties, penalties, privileges or benefits.""

"What California needs is a compelling justification for distinguishing between (i) religious worship services and (ii) the litany of other secular businesses that are not subject to an occupancy cap.
California has not shown such a justification. The Church has agreed to abide by the State’s rules that apply to comparable secular businesses. That raises important questions: “Assuming all of the same precautions are taken, why can someone safely walk down a grocery store aisle but not a pew? And why can someone safely interact with a brave deliverywoman but not with a stoic minister?”"

"The Church would suffer irreparable harm from not being able to hold services on Pentecost Sunday in a way that comparable secular businesses and persons can conduct their activities"

that's totally crazy man
Well it most certainly is a human right. Religious or otherwise. That was actually never up for debate.

The question is that right can only be temporarily, narrowly, and non-discriminately suspended under extraordinary circumstances, and 5-4 agreed that is in fact what has been done.
Aren't they planning on doing it tomorrow morning?
The thought of a next-gen trillionaire spending the millions of dollars required to launch a freaking rocket just so he can get to Europe in twenty minutes instead of the couple hours a supersonic airliner would take.. man, talk about ostentatious.
One of my favorite features is pure speed, while still having a lot of functionality.

If a production bug happens and I need to quickly debug, not much is faster than:

- "k9s" (start the CLI)

- "/myservice" (search for the pod)

- "l" (open the logs)

- "/Exception" (search the logs)

Maybe the bug was a bad config file I need to manually edit:

- "<escape>" (close the log view)

- "s" (exec into the container)

K9s has almost completely replaced "kubectl" for me as well. And the dev team behind k9s is great too. We get a new patch about every week and a new feature every 2 weeks or so on average: https://github.com/derailed/k9s/releases
Your perspective is positively dystopian. You literally have no understanding of the issues that others face that are materially different than your own. The majority of the poor are all around you doing useful work not drinking and drugging their imaginary free money you think welfare gives them to buy washing machines away. The rich and the poor often face the same challenges. For example they do stupid things. They lose a job. They develop a medical condition. They fail some classes. Someone around them dies. The get divorced. Money means you have tools to get past roadblocks knowing that in the meanwhile your entire life wont disintegrate beneath you if you stall out for a short period of time. The poor instead watch their life fall apart trivially easily and fall between the cracks or more often soldier on leading lessor but still productive lives.

They are often poor because although they do a substantial degree of useful work society doesn't value the work they do very much because there is more than enough people available to do it instead of starving. This is how economics works. Let me reiterate, most poor people in America work! Your particular myopic world view is common enough it has a name. The just world hypothesis. I'm sorry you can't see the people around you very clearly. I'm poor. Nobody has ever offered me money to buy a washing machine. I don't do drugs. I don't like McDonald's. I don't get drunk. I have a job but my wife cant due to medical issues and receives no help of any kind because of it. Most of my money goes to buy food, shelter and medical care. If you walked by me you wouldn't notice that I looked especially poor. I dress decently but virtually my entire wardrobe is courtesy of better class thrift stores where I paid aprox $2 per item. Last year I probably spent about 30% of my earnings on medical insurance + care alone.
HTP may be (comparatively) non-toxic but that doesn't mean it's necessarily less dangerous. The Kursk (Soviet ballistic missile submarine) was sunk by a malfunctioning HTP torpedo.
I like the alt-ed world too, but the person you’re replying to is correct: a 12 week boot camp is the equivalent of what? maybe one or two courses? Not even the same ballpark

Ask HN: Is touchscreen right for SpaceX Dragon?
Kudos to the SpaceX and NASA teams on today's incredible launch!

I've seen a few passionate comments on HN about the touchscreen interface, and I'm curious what you all think.
If this really represents (in general) the weight and efficiency you're going to get, then electric planes of this size will have to remain a specialized niche for only certain kinds of rare flights.

At 100 miles max range, the people would be better off driving, unless you're talking about mountainous or water-crossing flights where there is no alternative. (plus think about the added overhead of getting to/from airports, etc)

You have to wonder why they chose a 208B -- when you would generally try for the smallest and lightest plane to start with. Answer: because they can't fit enough batteries in a smaller Cessna to get it to perform on a reasonable flight. The ideas elsewhere in the thread about having electric planes lower the cost of training flights, etc. won't work if you need a bus sized plane to hold the batteries.

The plane has to be half empty, and even then can only eke out 100 miles. That's like a half hour of flight. A $2-3M plane can only handle a 1 hour ~50% duty cycle, max? That's not gonna...fly.

I'm not intending to sound discouraging, and it's an interesting demonstration, but fundamental energy density of battery chemistry is a bitch.

Edit: why, for the love of god, would they include that ear-destroying audio with the showcase video clip?
You'd think so, but that's what they said to the astronauts on the stream today.
I'll start off the discussion with some thoughts from the astronauts themselves: https://techcrunch.com/2020/05/04/this-is-certainly-differen...

My first reaction is that the implication the Korean war was somehow being planned by the US at the time of the Japanese surrender is some crazy revisionist propaganda.

But can you elaborate on what you are trying to say and what supports it?

That's paper, sitting on top of a traditional tablet with a glass screen (maybe an iPad, maybe an Android tablet.) There's a pen or pencil kept in a slot in the pack strapped to his leg underneath the tablet.

That's as much as I was able to gather from today and Wednesday's livestream.
Thanks for the correction! Totally my mistake.
How much weight should I give the opinion of someone who calls someone who disagrees with him "the pedo guy"?

It's a serious question. Elon may run some successful companies, but beyond that his credibility has taken a beating on any number of fronts.

How much credit should Elon get for heading companies full of other people who do the actual work? Could another leader do a better job, given Elons unsteady behaviour?
I worked with a PM whose husband worked at SpaceX; he'd recently left. I checked his credentials; they were very, very impressive, far above my pay grade, and very qualified for any kind of aerospace job. On LinkedIn he seemed like he might qualify as a 'genius', or at any rate as a very educated person who would be a credit to any team. He'd reached management level.

He was a little jaded about it, and told a story that seems a little familiar from some other big names. According to him, SpaceX wasn't a great place to work, because they pushed their employees extremely hard and didn't pay true market rates. So when he jumped ship he immediately increased his pay by some impressive amount - I don't know, 25% (and he probably made a multiple of my salary going in). Bottom line: it was a bit like the games industry - why work yourself to death when you can work for a bank for more money for less work? There were other commercial space orgs doing good work, so he went to one of them for an instant upgrade.

I don't know if he met Elon or not, but Elon wasn't like striding among the rockets or anything, this guy's division had plenty of work and it sounded like they had their noses to the grindstone with or without Elon. (To be fair, this wasn't a criticism of Elon's leadership, just an observation about the day to day - work, work, work).

I wasn't privy to the details, so I don't know much the equity was worth (seems like it would be more now - this was circa 2015). But that was his take, consistent with that of some other big name companies, where the brand itself is a sort of 'reward' that makes up for shortcomings in other areas, like salary.

Disclaimer: I'm not this guy, I'm just reporting on his experience, as told secondhand by his wife. This is an accurate retelling of that assessment, not my own.
I think you are projecting your opinion.

>all you would have had to do was stay home, is the very definition of selfishness.

Staying at home for extended periods is not the easy thing people seem to project. Social gathering are very important to a lot of people. Religious gathering are the same.

Telling people that there is no "risk analysis" here is both dishonest and dangerous.
You missed my point. My point here is that reasonable people can disagree if you just take a second and think about others' perspectives, workflows and development setups. But no, Linus is literally arguing that reasonable people cannot disagree because he's arguing that an 80-column limit isn't "reasonable." That's a bunch of bullshit.
Not sure how Fuchsia is supposed to solve this. If you can port those Qualcomm SoC drivers to the fixed Fuchsia interface, you could just as easily port them to the mainline Linux kernel and submit them upstream.
Wouldn't it be great if there was a large system for integrating all those data based microservices, taking care of data coherence, type verification, and schema migration, all of that behind a standardized interface that every language supports?
Hafnium Controversy
The date the airport was built is nor always important. People in my area are upset because FAA nextgen approaches always fly precisely over the same guy's house every time, where they used to be a bit more scattered. Now the Oakland airport was built in 1927 and most of these houses date from the 1940s, but air travel has increased a lot on the intervening decades.
What website am I browsing?? Google it my friend... Also Craigslist.
Ding ding ding. I agree one hundred percent. This isn't elegant, this is needlessly over engineered and now much more likely to slow development. The biggest cost isn't lines of code, it's understanding abstractions.

What happens when an "abstractnotifier" blows up? Where does the error happen? what are the possible side effects? What systems might be impacted?

What happens when 'alert's start failing? Is it queued/buffered? Do I need to worry about OOM errors on systems? Will it retry?

I lead a team of developers - This kind of abstraction tends to slow everything down. The only place it fits is during a refactor of software delivering real business value already. Basically - You can do this if you know exactly what your requirements are, and this nicely solves them.

If you do this before you understand EXACTLY what you need, you're going to be wrong. You will abstract the wrong pieces, with the wrong assumptions. I promise you. Then later you have to rip it all apart anyways, except now instead of 4 simple lines with clear consequences, you have a bloated monster of bad assumptions.
Perhaps a more interesting comparison is between Elon the CEO of Tesla and Elon the CEO of SpaceX. You may notice that these are two very different personalities that serve two different corporate requirements.

The Elon of SpaceX introduces himself as "I'm proud to be here representing the SpaceX team." The Elon of Tesla is smoking up on camera, throwing humongous ball bearings at the Cybertruck windows, sleeping in his sleeping bag while trying to bring Model 3 production through the Shadow of the Valley of Death.

You almost never hear about any of Elon's direct contributions to SpaceX whereas he's mister Tesla front and center at Tesla pulling stunt after tweet. SpaceX servers a very conservative industrial market and Tesla makes consumer products. These companies require to very different types of leadership. Who is the real Elon behind this public Jekyll and Hyde dynamic? Most likely it's the driven "man of first principles" just doing what needs to be done.
When you say internet, I'm going to say you really meant the world wide web?

Yes. Because the Earth is so much more massive than the ISS, the Earth-ISS barycenter is probably a nanometer at the most away from the Earth's own center of mass. So even though technically it isn't true that the ISS is orbiting the center of the Earth, it's close enough for government work (and the barycenter is certainly inside the Earth)
Won't they just recreate Earth's social structures on the Moon? Possibly with divergence over time but why would they suddenly abandon racism and nationalism?
But the spec usually has some implicit assumptions. Usually it's "app doesn't leak memory" in the same way nobody explicitly specifies "result of an addition of natural numbers should match ...".

We don't go around saying "oh, you didn't want modulo 5 arithmetic? You should've put that in the spec, not rely on some contrived absolute truth".
Unemployment and poverty are always going to be there and never be 100% removed. Not in the near future.

Wouldn’t starting a space mission create thousands of direct and indirect jobs?

These advancements are not taking money away from them. The research we did towards all of the space travel in the past 6 decades have given us dividends on several fronts.
There are plenty of examples, but I think to call that the zeitgeist is overstated. I mentioned in another thread in a different context, a near-future SF book from the early 90s, which posited an early 21st century war with Japan and the US on one side and Russia on the other, I forget who else. Things changed very quickly in the bubble-era.
Or flying "recharge" stations where appropriately sized drones carrying a new set of batteries (not necessarily all of them) would dock with the aircraft, push the new batteries into a receptacle while taking the old ones on board, then separate from the plane and land to the closest ground station for recharging until next plane to service.
So there is no logic explanation of the problem. I am fine with that answer, no need for more.
I don't follow. Why put all this work into optimising Quicksort without even mentioning that a superior algorithm has since been discovered?
Was that the tool requesting to be cited if it was used anywhere near a publication?

I wanted to use it but also wanted to respect the wishes of the author, so, as I disagreed with the note, had to use something else.
Welcome to Postnormal Times (2009)
No idea why you're being downvoted... I also think that would be one of the most obvious areas where Google could eventually put Fuchsia to use - it would have several advantages: a new OS with a more modern architecture (getting rid of the GPL-licensed Linux kernel, which Google probably sees as an advantage); the possibility to update the kernel independently of the drivers; getting rid of Java and its legal liabilities which Oracle could exploit in the future etc.
There's also https://infra.app which is really nice for a quick peek into the cluster.
Here is a PDF of the paper where you can also see the code examples embedded in the text: https://www.researchgate.net/publication/250809396_Plankalku...
Once upon a time, Linux had terrible support for laptop hardware. Remember ndiswrapper? That thing you used to get Windows wifi drivers working on Linux. Or how about when ATI (AMD) provided only the most buggy drivers. How about printers?

These days Linux has better hardware support (imo) than Windows. Solving it for laptops was about creating the right incentives for hardware manufacturers. It can happen for mobile too.
So whatever happened to Virgin Galactic? I know they were planning a reusable spaceship that would focus on tourism first. Was the plan just too complex in comparison to the simpler capsule-on-a-rocket approach? Or do the economics not stack up?
Eric is highly recommendable. He has lots of free lessons on Youtube that provide a foundation for all styles of singing.

I've also heard that long distance prepaid calling cards had the same fungibility + market.

I think you got it on the nose. I think folks who engage in more “traditional” arts (painting, music making, ...) really develop a distinction between these often interacting concepts. When playing an instrument, you distinguish between creative interpretation (art), musicality & sonic control (aural craft, imho), and manual or corporeal dexterity (technique). Of course, one’s ability to communicate a musical interpretation is propped up by the

(In very rare circumstances I might consider a program to be art, like the original metacircular Lisp evaluator, even if the author’s express intent wasn’t to appeal to somebody’s emotions.)
Hm interesting, so is there any analysis / theory that will capture branch mispredictions?

e.g. like big-O for something closer to real machines.

I feel like CPU cycles should already be analyzed separately from memory accesses (although I guess they are usually proportional). But analyzing branch mispredicts seems harder

How does this hold up on ARM and other architectures? (RISC V, etc.)
I've been waiting for some analysis like this. There have been pushes for hazard pay for a lot of critical lobs, but there hasn't been much information show what's actually risky.

A big takeaway from this is that the main part of the food supply that's at-risk is meat production, so while people might have to eat rice and beans, the food supply should otherwise hold up.
Because NASA isn't just free do things with that knowledge even if somebody could pay. You live in a total fantasyland when you believe that NASA just having some IP does any good for anybody.

You need manufacturing base and a business model to sustain commercial operation. NASA is a government agency that gets its priority sets by a congress that is not very interested in space flight, and putting the budget wherever they want at any given time. So NASA could have lots of IP about 4 different vehicles that gets into LEO but no amount of money could actually get you there.

They can give the IP to a 3rd company of course, but because they way it was designed it would not really have any commercial use, and likely it only works connected together with other government IP/hardware that you also easily get.

Now you have a private company, who has a very clear business intensive, to get the greatest possible use out of that IP, it only uses other commercially available tools and has synergy with other parts of their business that also has other commercial uses. The industrial base and teams are sustained, and not removed when congress lowers budget for a year.

So the Dragon 2 works with Falcon 9 rocket. SpaceX always operates Falcon 9 launch pads and they have plenty of rockets to fly and a manufacturing base that makes more of them. So now you have a much easier time to get the whole system together for an actual 3rd party flight, as the rocket, launch pad, infrastructure is already there and commercially operated.
Escaping planet Earth is a reasonable goal.
OP here. The code presented in the blog post was just an example although your points above are well taken. Practically, the decision to do abstraction or not depends on the use case and requirements.
I've recently taken to listening to almost everything spoken at 1.5-1.75x speeds. Content creators on YouTube have taken to speaking v e r y slowly, adding a lot of useless fluff / filler, or both. I see it in almost every video that I watch today. It seems like everyone is chasing that magic 10 minute mark with videos containing 2 minutes of actual content.

The side effect being that I am able to track things much better now at that speed and I can bang through podcasts much easier now that I've acclimated to the faster speeds. Really recommend this to anyone who also listens to a lot of podcasts or audio books, it's a good hack to get more content in.
BS. Do you think for a second some Tesla engineer or Elon Musk himself could design the most important control panel on a spaceship to look pretty without the support of the people who have to use it? If the astronauts or NASA engineers weren’t ok with it, it wouldn’t be there.
> and many people spouting them don't really want to roll up their sleeves and turn this ship around

I don't know if I agree with you here.

> It's as if the mainstream is using these even sicker people to pretend it itself is not sick, contrary to the mountains of evidence.

I feel quite strongly that this is happening.
This kind of jumps into 'scenius' without explaining it. It links an essay which would be a much better submission: https://www.packym.com/blog/conjuring-scenius
I did think about going to the kind of electrochemical reactions which might provide power to a motor. I believe the flow batteries are low power density binary fluid systems so not very flight suitable.

So then I went to ascent phase. Detachable battery with glide home. Keep smaller battery for controlled descent phase.
