I'd consider that even more dangerous. Stick pushers actually activate before the plane stalls. These large aircraft are designed in a way that a full stall could be catastrophic. Stick shaker events (the thing that happens before the stick pusher) happen quite frequently due to pilot inattention. In this case, an accident occurred, however, more frequently, they save lives.
Entropic forces are not more real than centrifugal forces or the Coriolis force. They appear when we use a thermodynamic description of a system.

That wikipedia page doesn’t make much sense, but note that the “mathematical formulation” is about macrostates and canonical ensembles.

I can't help feel that this is quite misleading - let's take a bunch of concepts we happen to like about our software team and project them onto a 17th century craftsperson.

I mean, you can construct a picture of such a blacksmith being Mr Super Customer Focused, sure, doesn't really make it true though? Why add in such an extra layer of distraction when you can just, well, describe good software team members?

Yes there is. There is no valid reason for a glorified headphone driver to mess with what website your browser trusts.
The method these use, retracting the blade, and jamming it into a block of metal to stop the momentum would not work on a aircraft.

This method (whilst pretty amazing) does not work outside of a static machine. You would need a couple of tons of metal attached to each rotor, and thats before getting into what would happen when you actually try and stop the rotor.
I work remotely and find myself working from a lot of Starbucks. The music level seems consistent no matter where you go to the point where it feels like a policy. It is just loud enough that you can't drown it out with a good set of headphones or take a conference call without annoying the rest of the group. It seems too consistent to be unintentional.

Conversely, there's a new coffee shop in Chicago that is designed from the ground up to facilitate work. It has tons of natural light, freely available whiteboards and almost no music call Limitless coffee. It is such a joy to not have to deal with the din that I go there even when I'm not working. You can almost hear yourself think.

You're welcome. Amadeus, Sabre and Travelport are now independent companies. But indeed all of them were initially parts of airlines, that were then spun off.

Sabre for example was originally American Airlines' system, and Amadeus was initially created by a consortium of european airlines in reaction to the threat of american hegemony on this market. They are now far more profitable than their parents :)

They were all originally heavy mainframe operations (IBM TPF - which was quite an impressive system... in the 80s), but there is a transition to modern architectures. Amadeus have completed the transition to Linux boxes, Sabre are still ongoing. They both have some of the biggest civilian data centres in the world

Novogratz's Crypto Trading Desk Lost $136M in Nine Months
Refined data probably means getting insights from the vast amount of aerial imagery (and related like SAR or elevation model) data that has become available in recent years. Having access to the data is one thing (e.g. Landsat and Sentinel provided by Google, Amazon and other parties), but processing it efficiently is still non-trivial.

Examples include Land-Cover-Mapping (mapping pixels to classes like forests, urban areas, water, etc.) which can then further be used to do crop monitoring or land-use monitoring.

I guess this is different than the product AWS is offering here, which is more about getting the data from/to the satellite, but not about processing (at least for now).

>> a perfectly uniformly distributed of zero temperature mass ... is the perfect order

At max entropy, things would not be uniformly distributed: equal distance between each atom. Rather they would be randomly distributed. There'd be some clumping but without much pattern. If such a system were of near infinte size, the number of variations of its alignments would far exceed the much smaller near-infinity of slightly or somewhat more ordered possible systems in the same universe. Especially in the case of your uniformly ordered one, which is almost unique in that universe.
Google doesn't list years of experience per technology but they do have hard tiers for years of experience and their salary bands. So they don't care that you have 5 years-of-experience with Python but you're not allowed to be an L5 without 5 years of industry experience.

Good to know - I visited Paris at the end of the eighties, with friends, and it was a terrible experience. After two days we fled the city. I was yelled at when trying to buy metro tickets, because my pronunciation and word selection was slightly off - I remember I literally backed away several steps from the counter. Restaurants.. all bad. We met a total of two nice people, one young guy with a button which said he would speak English, and an old woman who didn't speak a word of English but still came running when she saw us studying a map. They were both very helpful. Everybody else? Not very much. Not at all, really. Train stations, other public services - speak perfect French, or get ignored (at best).

And at that time I had been travelling to lots of countries for years, and I never had any trouble communicating with people. Big cities, villages at mountain tops, desolated island towns. People were nice everywhere. Except for Paris.

If that has changed for the better recently then that's truly good news.
Expect many liberties to keep length sane. First thing to find was significant survivors for ransoming back to the enemy. A good chance to loot for gear.

The levied men, as opposed to those in a Lord's retinue, were often little more than a poor unskilled peasant with knife, a little later they were expected to turn up with at least a knife and bow or for better status a polearm, shield and helmet. By Agincourt there weren't many levied men in use.

They might find their first mail shirt (with a couple of holes) to loot, or a better weapon. Maybe a leather jerkin with more hit points. ;)

There's obviously the more traditional plunder if you capture a town, but the travelling army would constantly loot and raid locally to supply and eat on the way there and back. Lords would expect any fancy valuables.

We often get totally the wrong idea from TV and film where everyone from way back has a distinct and new uniform with common colour, a nice crest (reserved for nobles), and nicely matching shields and flags. I get the idea if it became hand to hand it would be bloody near impossible to tell friend from foe.

The children or archers would go searching for arrows at the end of every battle for any that could be reused. Most would be damaged of course. Anything to increase supply was worth it as they fired so many.

Hope that gives a flavour. :)
Recently I've seen a lot more job ads with minimal technical requirements and rather a focus on more generic skills.

That's good but please, if you aren't Google or Facebook, don't take it to the other extreme. If I have no idea about your tech stack I'm not going to apply, and the same probably holds true for a lot of experienced developers.
Could be, but what if the requirements you're missing are supposedly essential for the job? Some jobs say you need to know X programming language. What if you're a good programmer but haven't worked with that particular language? Should you bother to apply?

The Met Office in the UK has a canteen, and at one point, they decided that it was too noisy. Their solution was to make a load of person-sized wool "clouds", and hang them from the ceiling. They look cool, and they absorb noise.

> We need to increase automation and, little by little, continue to remove the pilot from the equation until we have pilotless/single-pilot commercial aircraft.

there seems to be a growing consensus in the self-driving car debate that incremental automation is actually pretty dangerous, or at least much less safe than either fully manual or fully autonomous control, to the point where some consider it irresponsible to sell L3 autonomous vehicles at all. is there a particular reason why planes should be different?
Since we are in the fallout stage now, it is important to note that this news is poorly received within China, with most organizations against it or denying ties with it.

Nobody will issue Sennheiser a certificate for this purpose. Every so often a company abuses a cert they were issued to do what Sennheiser wanted to achieve here (local loopback HTTPS) and when they're caught the cert is revoked and they get a slap on the wrist. Blizzard is a recent example.

The Right Thing (TM) is to not do HTTPS, a modern web browser is supposed to conclude that ::1 and 127.0.0.1 are secure without HTTPS since there is no possibility of a "man in the middle" of your own computer's loopback.
That's precisely what I meant. Thanks!

There are people that legitimately believe Earth is flat.

For something less crazy, people were wearing surgical masks in photos of the California fires the past few weeks. They are wholly ineffective, a proper respirator with the appropriate filter is needed to make any impact on the air quality.

More oft than not people will readily accept something as fact without questioning it at all. There are countless YouTube videos that prey upon this, like the 'DIY drone phone case' and the videos with people alleging 'make diamonds with peanut butter and coal'.
At a cost.

There are several consumable components involved that have to be replaced every time it goes off. And it's less that the saw is stopped instantly which prevents the damage, but that it's explosively retracted away from the finger and then stopped. And, as lamented by many wood workers, damp wood can set it off as well.

Of course, that's a small price to pay in some cases.

Show HN: Notably, a minimalist markdown notes app
Hi, I just launched a new app called Notably and am looking to get some feedback:

https://notably.cc

Notably is a web based notes app that supports markdown syntax and is intended to be as distraction-free as possible. I've never found a notes app that I've been totally happy with, so I think there may be a gap in the market for something like this

Notably is completely free - I may add premium features at a later date, but for now its just an idea that I'm validating to see if anybody finds it useful

Thanks for looking,
Chris
There is a very big difference between blocking the public (both consumers and business) from dealing with companies from someplace, and blocking companies from that place from getting access to critical infrastructure.

Especially if said company is controlled by its government.

Especially if said company has been caught using said kind of access to spy for its owner government before.

Especially if said country has made a reputation of systematically stealing all the tech and spying any way it could on you to use it "against" you.

Especially if said country is not part of the same geopolitical block as you.

Especially if said government does the same thing to your own companies in the same field.

Confusing regular commercial dealing and critical infrastructure deal and acting like they have the same security need or that one leads to another makes no sense to me, so your comment is, in my opinion, out of line.

The Pilot Who Wanted to Be Steve Jobs
A traditional stick pusher is a much better design: the pilot has clear visibility into what's happening, they can see that the plane is pitching down because the stick is being pushed forward. Pilots do make mistakes but so do automated systems; the way forward is to build systems that collaborate with the pilot rather than cutting the pilot out.

Rivian Wants to Do for Pickups What Tesla Did for Cars
And the myth that great developers are always trying out the latest new thing.
Experienced recruiters (and employees) can see through the BS of job descriptions. Once the right candidate gets an interview it often becomes very clear there's a "match" to everyone involved and folks don't even bother to look at how closely they've "checked the boxes" in the job descriptions.

Sadly, many talented tech candidates early in their careers tend to interpret job descriptions far too literally and self-select themselves out of good opportunities. These same candidates also rely too much on responding to impersonal web-based job-postings rather than working through their networks of contacts, or just putting themselves out there and reaching out to real people.

I worked at a startup that dealt with these scanners (sending patient info to them so nothing very sexy) that had a lot of input from radiologists. They also had the same belief as this — there’s always something wrong in the body so if theres not a complaint from the patient about a particular issue they either will gloss over it when looking at the charts or they will flag it to look at some more.

One of the issues here is that a full body scan is typically done at a low resolution to save on time and disk space. These scans aren’t good enough to make a diagnosis from and leave the radiologist in the position of wondering if a couple of pixels could be cancer or is something normal. When your practice is on the line for making a call you will tend to err on the side of caution and recommend everything be looked more closely unless you can absolutely rule out a problem.

I was a little shocked when finding this out. I always thought it was like getting your blood tested and it coming back with a couple of the dozens of items that they look at being high and that could be a concern. It is much more inexact than that.

Ask HN: Is it still worth selling technical courses?
I want to make money from a product but I don't have a good idea for SaaS or anything physical for that matter.

But I have niche technical knowledge such as blockchain, cryptography, functional programming etc and a knack for explaining it well.

I figure publishing and selling a technical course is a good intermediate step towards making money outside of a job.

Is there still demand for technical video courses out there or is the market flooded?

Yeah, I'm a big fan of spaces that feature both "noisy" public spaces as well as quieter private spaces. I worked at an offie with such an arrangement and it was quite nice.

There's really no reason why there can't be both, especially a library.

In fact a lot of libraries do exactly this, don't they?

Typical library arrangement, at least here in America:

- Center of library has long tables with multiple seats; can be used for group interaction
- Sides of library have all the bookshelves
- Between the bookshelves and the outer wall there are more private desks. It's naturally quite quiet here because even if the central "public" area is noisy, you have all the bookshelves between you and the central area
[QUOTE]Rivian is using standard cylindrical cells, like large AA batteries, built into packs. But then it’s cleverly sandwiching two layers of packs together, with the liquid cooling that batteries need sealed in the middle. Scaringe grabs a pack to show me “the flow has been optimized to make sure the maximum temperature difference between the hottest and coldest cell of the pack is less than three degrees.” That’s important because lithium ion batteries are happiest in the same temperature zones as humans. He gets excited again as he explains the cooling loops for battery, traction system, and cabin. “It’s so cool, the battery and the thermal system are my favorite parts!”

Double-decker batteries helps Rivian promise huge 180-kWh and 135-kWh capacity packs for its vehicles. The largest pack Tesla now offers is 100-kWh. Its testing shows 450 miles of range might be possible, but it’s a long way from EPA tests with an official rating to prove that. Although Scaringe says his team has has worked hard at smoothing air flow, a truck is not an inherently aerodynamic shape, which means freeway driving will be far from efficient.

Eventually, when Rivian is entirely happy with its battery pack design and manufacturing process, it will have to scale it up. As Tesla has shown, that can be the tricky part. The company will do mass production at a plant in Normal, Illinois, with deliveries due to start in late 2020, and sales targets of 50,000 vehicles a year in the US.[/QUOTE]

The concept of a quiet bar just seems weird to me.

The problem with most bars isn't actually the volume of the music, but the loudness. The speakers are generally cheap speakers that are undersized and are then cranked so loud they're redlining and sound like shit.

I can stand in the middle of a nightclub with a well set up speaker system and have a conversation with a friend. Yet in most bars and pubs, which are places where I'd actually like to have a conversation, I have to shout at my mates and can barely hear a word they say.

This forum is on an intersection of progressives, who by default champion womens' causes, and entrepreneurs, who favor expanding labor pool to lower workforce costs.

HN will needs to see a lot more papers & articles on this subject to start turning around on the issue. Find more documents, post them, and hunker down for a few more years. Generation Z will get this sorted out once it starts joining the workplaces.

Point in case, most of HN is staunchly pro immigration with little to no restrictions, for what seems to be mix of ideological reasons, and labor pool expansion reasons. However there's a glaring exception: the (american) H1B visa program. A lot of HNers have learned of the magnitude of terrible abuse and wage suppression the H1B holders suffer, and thus prefer serious reform of this program. Awareness of the facts on the ground makes one question the ready-made ideological answers.
