I resumed flying after 20 years on the ground a while ago and of course discovered that I have a fear of it.

What helped me was the sight of the shuttle driving us from the airport to the city almost rear-ending somebody who cut it off. I realized then that aside from spacecraft the machines we use are highly dependable - it's the interaction with other people that's the most dangerous thing.

Currently the moment we're in the air I'm calm, but there's still some residue anxiety during takeoff and landing.

I don't fly a lot now though because the level of comfort comparing to a car is abysmal.
> You're not alone my friend, those IBM docs certainly are not easy to read/understand.

Just as for Unix, Linux, Windows, and so on, there's an IBM "culture" (terminology, conventions, etc.) that you have to get used to. (It often helps to know some of its history, too.) But since I grew up professionally with one foot in the IBM world I usually don't have much trouble at all reading their docs.
That's one of the wildest things! We had the technological capacity to run Unix systems with several hundred users simultaneously and access at the speed of thought with 26kbps modems back in 1992, complete with instant messaging and personal directories! What happened?!
Whats the difference in performance

It's not so bad (or maybe wouldn't be if cars themselves weren't so expensive.)

Assuming some even distribution of avaialable vehicles in an area, time-to-pickup scales like (area/vehicles), so the returns to scale diminish fairly quickly.

And "evenly spaced vehicles" might be the worst case depending on user preferences. It might be better to have fast pickups in some places and really slow pickups in others than average times everywhere, so long as users know the pattern -- slow from my house, fast from my work etc.
What's real mode?
Totally irrelevant but I wouldn’t agree Einstein was wrong.

QM without collapse is actually a fully deterministic theory. And it makes sense that the universe doesn’t play dice - because there is no source of randomness available.

It’s a functional language.

I work in 3D drafting & design, and CNC programming. In my life I've seen woodwork go from almost always boxes, to heavily jellybean, organic shapes. Because we have the tools to do it, people want it. Any less looks dated.

Houses will go the same way as the tools become available. In the yacht business a new design took a room full of men a couple years to design and draw, so they were slow, serious business. Now it takes three guys at computers six months. So people expect it: a new design every year at the boat show. Go two years without and bad rumors circulate.
I regularly fly on intercontinental lines over the Atlantic. Sometimes a strong turbulence happens while we are somewhere in the middle over the ocean. I usually afraid there's no emergency airport thousands of miles around us literally.
Let's assume that the fuel economy of an autonomous semi truck is comparable to that of a regular semi truck. supposedly the average fuel economy is 5.9 mpg which is honestly better than I thought it would be. For a trip from Seattle to Miami that's a 49 hour trip according to Google Maps which adds up to 3305 miles. That only adds up to 560 gallons of diesel which sounds like a lot, but look at the existing fuel tanks on a semi truck. Those things are massive. 150 gallons per side isn't uncommon for long haul trucking. Adding enough fuel to go nonstop from Seattle to Miami only adds 260 gallons of fuel which at 7lbs per gallon for diesel means 1,820 lbs. The maximum weight for a typical semi is 80,000 lbs so that's still only 2.3% of the weight that could otherwise go to cargo. But one thing to keep in mind is that without having to cater to a driver you can remove most of the weight of the cab. There's no need for a dashboard, heater core, air conditioning, steering wheel, seats, windows, doors, giant empty space on top for the driver, etc.

It would not surprise me if even with all of the extra fuel (which wouldn't even really be realistic because no one has a route from Seattle to Miami) if the weight difference was a wash between the two. At the very least so long as it can be loaded with fuel at the origin and destination it's not really a concern.

It's not, you are just probably not old enough for the ones that are legal.
Well, the fact is Germany has neither. At least in the US customers do get higher quality customer service and that is what matters. I would rather have a satisfied consumer experience than a useless set of laws and regulations that does no good to anyone.

As @always_good pointed out already, a flexible return policy is actually a competitive advantage for the company if they know how to conduct a retail business properly. I, for example, would always prefer Amazon to any other German online store simply because the confidence Amazon gives me when shopping. I can easily go on a shopping spree on Amazon knowing that if I don't like something I can easily send it back, although, during the last 3 years, I haven't sent a single item back to Amazon.
Misused image macros and pyramid schemes.
I think 'nature' would be confusing here, since we also use it for the concrete, manifest nature. As used here, and in many other phrasings, and by analogy with religon, 'god' is probably meant to be the principles and forces underlying manifest nature.
on the other hand some of the problems you mentioned were solved on Windows with WSL.
So I've heard that weather was not compatible with driverless vehicles.

However I haven't seen what happens when they are in heavy snow or rain.

And, I'm sure I'm misunderstanding the problem but couldn't electric cars with a motor per wheel be able to detect a slipping or loss of traction in an individual tire and slow it down?

Trust building and a seal of quality through peer review.

Basically, a paper that is published in a journal like Nature or Science or the field-specific top journals is assumed by the community to have been reviewed at much higher standards than those published in lesser known journals, just because it is much, much more difficult to publish in these journals. Thus a paper there will be a signal that you are a capable scientist.

Also, peer review is necessary as protection against crap. I am not saying that this is a fool-proof system, but science has to have one, preprints should exist but science needs to be reviewed and approved by professionals in some way, and the professional reviewers need to be incentivised to do a decent job.

Peer review may be the only asset keeping journals alive at the moment. I've been wondering whether traditional journals can be overcome by making high-quality peer review the focus of the business model.
I'm getting fed up with the for-profit scientific journal system. I was recently invited to submit an article to a new journal on computer networking of some kind. They mine publications and just start mailing authors, soliciting publications paid for by authors. I don't even work in computer networking! Ugh so I wrote back:

Dear XXX,

I mean you no personal disrespect. However after reviewing your request, I believe your institution serves no purpose in today's publishing world and absolutely will not be paying it USD 1,250 for the privilege of publishing of a paper in a field in which I am not an expert. Such a contribution would in no way advance either Science or humanity, but instead only create more confusion by frustrating several fields' fledgling efforts to sift the wheat from the chaff using a proper scientific process.

Wishing your institution failure in the sincerest capacity,

YYY

Google didn't have any problems with China...until it did. No court to sue either, unless you want to waste your time and money.
Sore losers always blame the system. Haters are going to hate. As a matter of fact, many American companies are doing very well in China. For instance, Apple, Intel, AMD, Nvidia, IBM, Ford, GM, Starbucks generate a large portion of its profits from China. They are doing very well. Ebay lost because its product and execution. Chinese internet companies are very competitive. They are relentless.
For us academics the ‘literature’ is our peer reviewed repository of scientific knowledge.

Various Journals have reputations in certain fields and publishing in such a journal is a measure of your ability within your field. I can glance at an academics publications list and get a good measure of their speciality within a field and the likely quality of their work.

There are various methods to add numbers to this. Journals often go by the impact factor and academics are measured by the h-index. Most of these are only relavent within a particular field as some topics are hotter than others and generate more citations.

Historically journals were run by various intellectual societies etc. Papers were submitted for publication and the editors would send manuscripts to other academics for review. All of this was voluntary, not unlike the old days of internet moderation.
Of course to distribute the printed volumes of the journal readers were asked to pay. All of this was considered reasonable.

What happened was that text book publishers began to buy up journals and sell tranches of journals to university libraries. You could no longer buy those three subscriptions you need, you’ve have to buy this expensive bundle, oh and you don’t get a print version, that’s extra.

So we now have a situation where government and industry fund scientific research. Academics, who need strong publications to get ahead, write and also review manuscripts for free so that some publishing house can claim massive profits for hosting a bunch of €50 PDFs.

It’s no wonder SCI-HUB, where almost every researcher I know pirates papers daily, has taken off.
I've been using a HP Spectre x360 (13") with Ubuntu 18.04 for the last couple of weeks and it's been working very well for me. I even use the tablet mode when reading PDFs.

Price wise it's quite cheap (same specs as the Dell: i7, 16GB, 1TB SSD, 4k screen) as you can usually find a coupon online. For me it was about EUR300 cheaper than the XPS currently is. So far everything has worked out of the box with exception of the fingerprint reader on the side.
And if nature was a programmer, I don’t see how that’s different from god.

I've already downloaded everything I need for perfect typography. I can apply it to most websites with Firefox's Reader Mode. Websites cannot possibly improve on this, because the best and most legible typography is the typography you're most familiar with. I don't care about branding or image or whatever bullshit "designers" use to justify their jobs. Web fonts and CSS have negative value to me. I disable them as far as possible.
> People can reasonably disagree on what constitutes propaganda, which is why I like the language that they are using here.

However in this case they're using alternative language to manipulate the reader that their judgement is correct.
Tbh they could email me articles plaintext and I'd happily hand over my money.
I am providing context as to why the statement at the center of this is confusing. It still strikes me as putting an unshared perspective onto a concept in a way that doesn’t make sense to me as well as the person to which you were replying. If you continue to disagree, feel free to, but the core premise makes little sense to me.
I think a mass driver in most cases would be simpler and more economical. We would use them on earth if we didn't need to worry about the atmosphere.

A Space elevator would require that the body spins fast enough that the centripetal acceleration would equal the gravitational acceleration. Ceres spins roughly every 9 hours - I haven't done the math but that seems like it could work in that case, but even so I would still vote mass driver.
> What I think is difficult is that most people think a website should be an experience.

People on the delivering end. Not the users. The users just want to get the content they came in for, and to continue with their lives. This "website is experience" is a combination of vanity and trying to monetize users better by playing on their emotions.
Do you know what the best way is to get my hands on one in the EU, preferably with a US keyboard layout?
Just because there isn't a free speech argument doesn't mean a communication company would benefit by going on a politically driven "banfest".

That comes with its own set of disadvantages.

* If you fire up an editor on the remote machine, there is going to be typing lag, unless your Linux machine is in your local network. You can ameliorate this with software such as Mosh, but that comes with its own disadvantages (losing scrollback buffers).

* If you edit locally but save the files to the remote system, you have to worry about getting disconnected or your machine shutting off and losing changes.

* If you edit and save locally, then transfer changes later (e.g., using Git), you run and test your code on the remote machine, and have to worry about attaching a debugger to the remote program and other fun stuff.

I guess it just depends on how big the project you're working with; but I would have a hard time working with more than, say, 10 files on a remote machine.

Other solutions aren't exactly optimal either. A virtual machine takes up precious RAM and it is slower than bare metal. You're not using all of your machine's resources. WSL works for most things, but fails for others (e.g., Docker, Kubernetes, I/O isn't as fast as it can be).

I've come to the conclusion that doing development on Linux on bare metal is the solution with the least compromises; the biggest one being the loss of access to work-related productivity apps such as MS Office, Outlook, and Adobe products.

One bright-side to the end of Moore's law is that--until some new computational breakthrough comes along--we are at a web bullshit plateau.

Just think of the stuff they could pull off with ten more years of speed-doublings...
The problem with bloat. That is, web pages are just much slower to download and render on mobile than on desktop. E.g. a page that takes less than a second to load on desktop can easily take ten seconds to load on mobile. But two or three years from now, that same page will load in less than a second also.
> Why is that doubtful? There's all kinds of examples of tiered subscriptions in the world. I think it would be doubtful because the NYT wouldn't want to explicitly admit all the tracking they are doing.

Many reasons, one of which you said. What would the price tag be for them to admit all they are tracking?
Wow that FAQ and license is confusing. They define personal use as:

> use solely by the person downloading the Product from Oracle on a single Host Computer, provided that no more than one client or remote computer is connected to that Host Computer and that client or remote computer is used solely to remotely view the Guest Computers.

This isn't a standard definition for "Personal Use" and I can now understand why people weren't happy.

Well, scheduling is important. I can't connect my new phone to the computer until I've taken it out of the box it came in.

It feels like I'm leaning to the imperative side. When breaking down the problem into substeps, I'm already thinking about the sequencing which will later dictate the scheduling.

I've been teaching Scratch[1] to 11-13 year olds for a few years now, and most seem to pick it up pretty quick. However a few struggle (while still being motivated enough to keep trying). Would be interesting to see how it went with a functional Scratch version.

> can't recall if you do or if it prompts you, but it is something you have to enable

It does. In fact, it keeps displaying an annoying blue-colored topbar telling you that your life will be better if you enable notifications (fortunately, with the option to snooze it or dismiss it completely on given machine).
I have found the same mindset to be comforting for me on planes. I am able to let go of control, because to be honest, I wouldn't be able to stop the plane from crashing even if there was a real danger.

Better not to worry about something I have no chance of controlling.
Globals make it really difficult to test, reuse, or repurpose code. And you can only ever have one instance of a given global, so if you want multiple instances of your widget you face really ugly refactoring.

If you google for it there should be plenty of good resources on this topic. It sounds like maybe you’re relatively new to programming - it only takes running into this situation once to start to understand the reasons for avoiding them.

They’re especially dangerous in JavaScript because of the way it handles scoping. If you accidentally miss a “var” or “let” inside a function you could find yourself mutating global instead of local data.

Vuex lets you scope your data to a module. It also as I described above lets you limit mutations to a known set of operations, which becomes important in a large or long-lived codebase.

Disagree, in fact i see it the opposite way.

Uber has a huge most that Eats adds almost nothing to. Every day millions of people reach into their pockets to request a ride using the Uber app. Competing with Uber means
a) recruit large numbers of drivers so your app has rides to offer.
b) convincing large numbers of people to download your app.
c) convincing them to make your app their primary ride share choice.

Even tackling a small city would be horrendously expensive. If it truly was easy Uber would be getting eaten alive by numerous small startups in every major city they operate in.

Ask HN: Do you have any PTO-use strategies?
I work as a programmer and historically I don't use PTO until I'm in danger of losing it at the end of the year. And then when that time rolls around, I have no idea what to use it on. Does anyone have strategies they use with their PTO to make sure that it gets used up and that they don't burn out at work? Exceptions, of course, being made for when you are saving it up for something.

While I'd agree that the likelihood is incredibly small, the second paragraph of your comment is incorrect. SWA 1380 happened just ~3 months ago and caused 1 fatality.

There was also Asiana 214 in 2013, which caused 3 fatalities when landing in SF.

https://en.wikipedia.org/wiki/Asiana_Airlines_Flight_214

Aside from those, it also seems disingenuous to exclude turboprops. 49 more deaths happened in America on turboprops during this millennium. That's not an insignificant number.

Free speech in America isn't just valued as a legal right before the government, but as a general principle. Most people think that free speech in most situations (not just before the government, and with a few restrictions) benefit everyone.
