I believe that the biggest obstacle in SpaceX's "hover slam" landing isn't calculating and controlling the burn but getting sufficiently precise input in time for those calculations. It must be a miracle of sensor fusion.
> We are extremely sensitive to the inner mental lives of others and respond both consciously and unconsciously.

This is so wrong it's hilarious.

Humans are terrible at ascribing meaning to what other people do. It even spawned a saying: "We judge others by what they do; we judge ourselves by what we intend."

As such, we, as humans, generally have zero idea what is going on in someone else's brain when they do something unexpected (it is unexpected after all). An individual has to work very hard to "cut others slack" under most conditions.

Unfortunately, there are quite a few bad social actors nowadays who attempt to take advantage of that, and there don't seem to be quite as many people who will take those bad actors on.
Well the page you linked to says "Estimate to be dispatch in late May, 2020". Considering that it's the last day of May today, I can't say that tells me much.
Find Friends to work with. You will help them they will help you. Exams are not like coding they need practice despite how well you know the topics. Sitting down for hours by yourself is near impossible. Sitting with a group helps to maintain focus and gives you someone to explain this. It also gives you someone to explain things too. Nothing will sharpen your ability to clearly answer an exam question more than teaching someone that concept.

Those same friends will be the start of your professional network. The more contacts you have the better for you career.

Finally try to intern during your holidays. Work experience will help you land a job.
In the case of SpaceX, it seems that they use embedded Linux and C++ with x86 processors, same as standard PC processors. A reason for using embedded linux is that, it allows using standard C++ or even scripting languages for controlling the hardware from the user-space by just reading and writing files. Linux device drivers (aka kernel modules) maps the hardware to special files on /sys or /dev. For instance, it makes possible to control a GPIO (General Purpose IO) which the device driver maps to sysfs special file system, by just writing 1 or 0 to the file a like /sys/class/gpio/gpio4/value which would enable GPIO 4 and turn on a LED attached to it. Another practical example about this feature is that, on Linux, it is possible to turn on or turn off the keyboard capslock LED by writing to some /sys/class/leds file such as "$ echo 1 > /sys/class/leds/input7\:\:capslock/brightness" which turns on the Capslock LED. By writing 0 to it, the LED is turned off.

This feature of Unix and Linux allows controlling the hardware with any programming language capable of reading and writing files, including Python and standard C++. I guess that they may be using standard PC hardware with industrial IO card. They may also use a single-board computer or custom board with x86 low-power variants processors built for embedded applications as SOC system-on-chip. One example of low power x86-SOC based processor is: https://www.cnx-software.com/2015/04/09/vortex86dx3-is-a-new...

>There is an objective truth

When it comes to the issues that "news" covers for the most part, this is highly debatable (and debated) claim.

There are facts that you can state, but even then, there is the choice about which ones to mention and which ones to leave out. Or even which ones to state first.
Per this interview in 2012:

“There were times when I thought he was off his rocker,” Mueller confesses. “When I first met him, he said, ‘How much do you think we can get the cost of an engine down, compared to what you were predicting they’d cost at TRW?’ I said, ‘Oh, probably a factor of three.’ He said, ‘We need a factor of 10.’ I thought, ‘That’s kind of crazy.’ But in the end, we’re closer to his number!

https://www.airspacemag.com/space/is-spacex-changing-the-roc...

This is in response to the engine. Maybe they got the engine price 10x cheaper, but the other components not so much?
I think using managing state with an observable data service is a pretty good option w/o resorting to 3rd party libraries:

Alternatively, you could use Akita, which is built on top of this basic model, but offers a ton of additional functionality and the ability to use Redux Dev Tools.

Finally, you also have NgRX, which is based on Redux--but also adds a ton of overhead and boilerplate. I actually opted for Akita since it is way more ergonomic and offers most everything I need.

I think the most thoughtful/fair approach is to use more than one factor: role, years of experience, costs of living (having kids? big or small city? etc.) and loyalty (how many years in our company?) are the most important factors that come to my mind...
Perhaps the government would not need to be downsized by reducing disaster preparedness programs and emergency stockpiles if it had not already been bloated by high salaries for bureaucrats.
Being a police officer is less dangerous than driving a taxi, but I don't see an epidemic of taxi drivers killing people. We need to stop excusing horrific crimes because of the relatively minor dangers that police face.

Yeah of course, SpaceX would be stupid to not use the resources NASA will make available for them. Honestly, NASA would probably much rather be out of the business of building rockets, so they can focus on the next generation of space experiments. The less money NASA has to spend on hauling stuff into space, the more they can spend on what they put up there.
Technically, but have you ever worked at a shell on an Android device? It feels alien, and all the interesting stuff is wrapped up in the JVM so the fact that it's wrapped in Linux doesn't gain you much.
I currently have an Acer B115m with Intel N2940, SSD and 8GB LDDR3.

I use this laptop mostly to work outdoors. I get somewhere nice, surrounded by nature, open the laptop, plug in my 4G modem and work from there. It gets me about 6h of real usage, but sometimes I can't charge it up to 100%. I'd also like to have a brighter scree so I deal better with sunlight.

Most of the times I go to places you can't reach by car, so I go on bike or walking, therefore I need to be careful with what I carry with me, be it weight or volume.

An ARM laptop would be a nice upgrade for my battery anxiety, but having everything soldered makes me uneasy, and 64 Gb HD + 4Gb Ram is not enough for me. Also, I wasn't able to find info about the screen brightness.

Just so you know, this is not an uncommon complaint in any romantic relationship.

You actually do lose information around the edges (it's cropped). But not much; the images are pretty compressible, so you can just predict those pixels.
That is an impossible accusation, as you could be wrong (plus too honest for own good), but the person would be masking better than you as well! Anyway, personal traits aren't criminal.

I've heard sociopaths even excuse their "eccentric inattention to others" as possibly having asperger tendencies! Most people still lack experience to even understand they are poles apart.

Regarding projections, burn the "rule book". Setting up "outside" people for failure is common but not enough to distinguish. Bullying, condescending remarks, getting others to chime in. It starts with boasting about the last victim, then you're next.

Only thing that can stop it is people stop tolerating abuse in their environment. USA is now "it".
I wish paying for news would actually make news organizations prosper. But subscription only slightly help. Looking at past revenue of the LA times, subscribers accounted for under 20% of revenue [1]. The remaining 80% was from advertising.

If we all subscribe to 3 or 4 papers right now, the best thing they can do for their business is bombard us with ads to make up for the remaining percentage. Well, we have adblockers now so it doesn't work.

I don't know what the solution is. Journalism that holds people accountable is crucial for society. But customers paying for the news doesn't work. It never did.

Is it really that maddening? This response feels much too political. There are things worth getting mad about, and then there are JavaScript frameworks.
Are you asking about what happens if all the power goes out or are you asking how they get state back? If everything reboots it’s fine. On restart the computers will look at all the sensors add project the state of now. There is no reason to keep the state of the past is there? Why does it matter where the craft was 5 minutes before? What matters is what is what is in front of them and the future right? If you tell the computer I want to fly home it looks at where you are and tells you how to get there. It does not need to remember the past parts of the trip does it?
> ...if we treated nonviolent people the way these videos portray.

A lot of the videos portray violent rioters/looters. A lot of the ones of the police are ambiguous because they don't show what behavior warranted the police reaction.

I've also seen a lot of videos of peaceful protests with police walking/talking/marching with the protesters.

We do justice a disservice when we lump everyone and every precinct together.
I would also be fascinated to learn this. Liked the idea for several years of gaining a PhD, but I just couldn't imagine taking three or more years out of my career at this point. The only vaguely-related anecdata I have is from my mother, in a completely different field, who was a nursery school teacher (kindergarten to our friends across the pond) with a strong emphasis on creative development, but only after retirement at 65 did she actually go to university and get herself a fine arts degree. Now she potters away in her little studio every day and will probably not be in any danger of losing her marbles.
This would seem to line up with some old wisdom I heard years ago, where some researcher interviewed elders and found that his subjects regretted chances they had not taken far more than chances they had taken, even if it didn't work out.

That idea was a big focus of mine as I tried to get over fear in dating.

I think there's a trap whenever you try and pursue an unbiased, universal perspective or theory or truth (and not just in this one space): it can be really easy to lose sight of your own biases and flaws, which always exist, and always impact your perspective. None of us can claim to be fully rational and removed, so whenever we try and venture into the realm of universal truth, we must always keep our own biases front and center and account for them as best we can. That isn't to say we shouldn't pursue those truths, but I think the point being made is that Rawl's framework encouraged people to sweep their own biases under a rug, which is a dangerous thing to do.

The occupation of police officer in the US is roughly as dangerous as being a construction worker. Police aren't even in the top 10 most dangerous occupations [1]. So this type of fear is not really justified and probably contributes to the problem.

UV light makes sense, humidity and heat does not, because if I am not mistaken; in summer humidity can be substantially higher then in winter and body temperature is fairly high compered to outside average.

They’re definitely not perfect though and you find some truly annoying configurations when you’re out in the world of public WiFi but for the most part it works.
If you go to /r/publicfreakout and sort by /rising, you will see LOTS of videos of some rioters being extremely violent.

Two sides to every story.

Peaceful protesters deserve respect and to be heard. Rioters and looters should be dealt with harshly by the law.
That's not my experience with a couple Google Pixels, using original quality.

If you fetch your image via takeout or via the API, the image bytes are the same, but the EXIF headers have been changed.

I've tried in both a standard Gmail account and a custom domain. Same behavior.

Are you saying your file SHA is the same from your device and your takeout?

I wonder if I am seeing US-account-exclusive behavior?
Thank you - that was an eye-opener. I have been on HN a lot in the past couple of months, and not noticed DM articles.

Perhaps I tune them out. Perhaps, also, I read the link title in an HN list and skip over any with gratuitous capitalisation of words for shouty effect. I also dislike tabloid-style tone in titles. Only if the title catches my interest will I strain my eyes (should wear my reading glasses for some screen use, but don't) to see the source.

However, there's no way that I should have missed what you pointed out. Thank you again for that.
For the UK scheme, companies can furlough staff. During this time they can't do any work for that company. The company can pay them anywhere between 80% and 100% of their normal salary and then the government will reemberse the company for the 80%.

That means that furloughed staff can be paid their full salary,but the company is only on the hook for 20% of it.

Anecdotally, smaller companies with few members of staff (who are financially able) are paying 100%, while most large businesses are paying 80%.
Probably the same tough behavior that's preventing rioters from burning down poor immigrant small businesses.

Human stupidity and the law of averages.
There are multiple existing third-party tools in the ecosystem that let you do exactly that:

- https://github.com/arackaf/customize-cra

No, they're not "officially" supported, and you basically void the warranty by poking the configs manually, but the tools do what you want them to do.

Nah, having been on active duty being involved in cyber warfare and later joining the corporate world, the latter is so much more advanced and interesting, with generally a lot better people.

> having 101 screens attached to your keyboard is pretty costly

I wonder if it would be somehow feasible to cut costs by using a projection scheme.

Perhaps each key could be essentially passive rear projector screen, then you'd have a system of mirrors, lenses, prisms, or whatever below the keys so that one DLP or other projection system could hit all the keys.

Maybe having 1 active component and 101 passive components (hopefully all plastic) would make the whole thing a lot cheaper.

Of course, there would be the small matter of building it so the geometry works out where you can have the image hit the key and also have a switch and spring beneath it.
> 1080p is pretty decent in a little laptop like this.

When did 1080 become regarded as acceptable, let alone decent? I remember running CRTs as high as 1440 about 20 years ago. What happened? Why hasn't resolution doubled a few times since then?

Keras API Design Guidelines
It's not at all clear that it was a mistake. Go has had eight years of being one of the more successful languages. If they had tried implementing generics right away, it may have taken longer and it's unclear whether Google would have supported the work for so long? Maybe the timing would have been different enough that they didn't succeed, or the lack of experience would have resulted in a design that's worse?

It's also not at all clear that Go will have similar problems as Python did, since the Go team considers backward compatibility important and might approach the problem differently, learning from Python what to avoid.

Counterfactual reasoning is difficult. Learning from history isn't as easy as some make it look.

The real solution is to dilute political power further not by eliminating it but expanding it.

There’s game theory to back up the idea of a balancing act by making everyone police.

Personally I’d prefer expansion of representatives (in the US, but it’s not too hard to translate to UK) and/or judiciary.

In the case of the judiciary, technology could be applied transparently via open source models of building case management, looking for patterns, weighting their correctness by social means....

That depends a lot on where you live. In Austria, for example, where I lived for several years, academic titles carry a strong social cachet and are used absolutely everywhere - on your credit card, bills from the city council for cleaning out your bins etc. People with more than one PhD will be addressed as Dr Dr Firstname Surname, someone with a regular engineering degree is allowed to refer to themselves as Ing. Surname instead of Herr/Frau. It's a really big deal.

That might be an improvement in many places, but it would probably create problems for San Francisco and San Jose, where cost of living is largely unsustainable for people who make starting police salaries unless they lucked into a family house.

We sometimes forget that officers get to choose where they want to work and will migrate to the best place for them. The ratio between housing costs and salary (among other quality of life factors) is pretty important to lots of officers and we may end up lowering the quality of officers by only restricting the pool of eligible employees.
