FTA: "The company is relying heavily on innovation in battery technology continuing to improve at its current rate. If not, the firm will not be able to build in enough power to give the plane the range it needs."

So, it presumably can't work now but they're putting their money on the idea that it will in the near future.

Farmers are an independent group. They are used to relying on their own skills and hard work to make a living, and they are not going to tolerate this. I think it is an overreach for John Deere and other manufacturers to control what I do with my (my!) devices. I really hope this law gets passed to prevent companies from doing this. Farmers can really help, because everyone knows we depend on them for our food, so anything that messes with them, messes with all of us. I think they picked a fight with the wrong people.
>A new start-up says that it intends to offer an electric-powered commercial flight from London to Paris in 10 years.

There is no way a startup without any experience in aviation will design, build, certify and sell a commercial 150-seat airplane in 10 years. Not even mention the immense R&D groundwork required to even prove the concept of using batteries to power short haul flights.

Why do they put out bullshit like this? It just hurts their credibility.

I don't actually believe this is true. I find that paper fascinating, and I believe today you could just simulate the hardware definition, rather than work straight on the bitstream and evaluate it in hardware.

I also believe that today's FPGAs are more robust against these kinds of bugs. Because, even with some HDL code, these defects or cross-talk incidents could result in difficult to debug errors.

It's an artifact of a tool. The same after-thought tool could have just dropped a mapping line in a .gotool file somewhere:

But no. We need to put that in every freaking file and thus transit from information to noise.
somewhat. LNG is sold on the basis of long-term supply contract. It's quite possible that LNG exported from Western Australia could make its way back to Sydney, Melbourne, other places if there is no pipeline infrastructure in place. the LNG import facilities compete on price, and in this example, Chevron would sell it to the highest bidder.

No one wants "stranded" gas, but it would be up to the Government of Australia to set up the pipeline to its major cities. I'm sure such a pipeline exists, but given the quantity of gas available, Australia may not be able to use it all.
A Latticework of Mental Models

As you say that depends on income. Based on location and whom you mix with. And perhaps some culture bias/patterns but that is my just guessing.

Macs have dominated in the areas I have worked in for the past 6 years. I would say in the companies, hands-on meetups and conferences I been to in London and across Scandinavia: 75% use macbooks, then perhaps 15% dell xps with ubuntu and 10% mix of lenovo, MS surface etc.

Though I think this split will change with the recoil of the new touch bar macs.

(Again this is just from my smaller demographic of location and people.)
Magical thinking is a very effective VC cash magnet, especially when you have entered the "fear of missing out" stage.

Uber is a company that has a 60 Billion dollar valuation contingent on the idea that it will somehow both develop driverless cars, and maintain a monopoly on them (dispite having zero expertise in this area whatsoever, and competing against entire industries that do) before they run out of money losing 2 Billion+ a year.

Theranos had promises of technology that was not physically possible, and they knew it. Yet the billions still poured in.

Magical thinking is powerful.
Normally I'd agree with you but seeing that SpaceX was able to go from zero to sending stuff into orbit in a decade, building a plane in that same time period doesn't seem totally unreasonable.

I'd be more concerned with the realities of battery technology not being ready and existing regulations/testing stretching the timetable v.s. pure technical ability of a team to design something that would be fit for purpose.
The equation isn't just energy density; it's also the efficiency of harnessing that energy. Good electric motors are way more efficient than a turbofan.
SpaceX did more than that in 10 years.

Largest installation we were involved with (though not me personally) was a 250k user base, for the Ministry of Education in my country.

The monolith is stateless, so it's pretty easy to scale. The painpoint is Postgres, but I think people underestimate what real hardware in a small cluster can handle.
Companies and governments do not want to flare gas. That's money just disappearing. To use this gas, however, you need to have the infrastructure set up to take the gas - you need fertilizer plants, power plants, etc that can use the gas as power. In the Middle East, these are not always possible in remote areas, so they flare it.

Natural gas is green energy because it's reducing dirty coal power plants. LNG terminals have nothing to do with fracking. LNG terminals are just an export facility.

> A concrete example: if we knew we lived in a simulation, and therefore knew that the simulation of an entire universe were possible, we'd probably expend resources on research and engineering efforts to create such a simulation.

It is pretty unlikely that an equal simulation would be possible, and we already know it's possible to create smaller ones; particle-physics simulations are common, though still incomplete.

In general, there's no requirement that the 'metaverse' follow the same laws of physics as this one.
ODBII has to be the greatest planned obsolescence scheme ever perpetrated. Want to continue driving that older car that is running perfectly fine? Sure go ahead and rip apart the dashboard to get at that sensor that happens to fail perfectly around 100k mile mark at a cost of about half the value of the car at the repair shop because it takes half a day for their tech to complete.

If it was about greenhouse gasses they'd let you keep the "dirty" car because the extra pound or two of emissions per gallon compared to a new car doesn't offset the carbon cost of building a new car from scratch.
9292 requires access to your contacts before installation. That's a non-starter for me.

TL;DR: If I read things right, the BBC article is highly misleading and the plane still uses jet fuel.

Longer version:

The article mentions "removing the need for jet fuel" but does not explain how the engines of this "electric" plane work. Propellers run by electric motors, or what?

No. Wright Electric's own site is scant on technical details and concentrates on praising the great team in its blog. From browsing other sites [0] it appears that the engines are still using conventional jet fuel to generate the thrust; it's just that the external systems (pressurization, de-icing, landing gear mechanics, fuel pumps etc) that are powered by electricity are using battery power instead of generator in the current jet engines.

This may be a step ahead in energy efficiency but is not that revolutionary, and calling it "electric flight" is simply wrong.

I hope I misunderstood, but Wright Electric really should tell how their electric plane is supposed to work if it is really electric.

https://electrek.co/2017/03/22/electric-plane-startup-150-se...
Retrofitting an existing jet seems like a vastly more viable option in 10 years. But, with sufficient funding it's possible to start from scratch and get there in 10 years.

1Password does not have a list of "secrets" that it draws from for all forms, it only saves the information you provide per-site; anything it submits to a site is information you've already submitted to the site previously.

1Password's extension does not prompt for my master passphrase, I have to click on it to enter it (if I haven't already). It also to don't try to fill forms on page load, I have to instruct it to do so. By default it will usually submit a form upon fill but I often turn off that setting.

As for browser vulnerabilities, I'm not familiar with any information about extensions being particularly vulnerable to browser exploits, it seems like when browsers get "pwned," anything in userland (if not the whole system) is up for grabs so avoiding the password manager's browser extension doesn't gain you anything. I'm not saying there's no risk, just that trade-off is worth it. Agilebits argues that using the extension is safer because it avoids keystroke loggers and clipboard sniffers [0]

My guess is that they are trying to create a hype around it to attract investors and make the success a self-fulfilling prophecy.

Even if they fail to produce a working electric airplane, they will make a lot of money in the process.
Has the tooling for RAML improved esp. around the licensing? Last time I looked, the 'standard' server implementation on the JVM had rather restrictive licensing, IIRC it was dual-license AGPL or a commercial license?

(AFAICT RAML is actually a much nicer spec, both simpler in some ways and more powerful in others, but as I say I was never actually able to use it due to the licensing issues on implementations -- only read it.)
It's back, sorry about that!
MGCOOL Explorer ES – A premium action camera at the cheapest price
But where does the difference come from?

A "well-designed monolith's" code architecture would be very similar to microservices - with separated modules, but in-process function calls instead of remote API calls.

If you do large-scale integration tests that cross module boundaries in the monolith, then you should also have the same tests of the full deployment with microservices. If you test each microservice independently, then you could also run tests for each module independently.
That doesn't seem right. If tomorrow the mass of your ashtray started fluctuating in Morse code, spelling out "hello from the simulation master" and replying to your questions intelligently, your first instinct wouldn't be to update the standard model.

I think GP's point is more along the lines of When the Ministry of Education and the Ministry of Whatever are both customers (separate instances) and want cross instance reporting.

We had this at one of my previous places, exactly the same setup. Identical monoliths * shopping malls, the issue is that Companies own more than one shopping mall and they really want cross mall data, something that was extremely painful to add in at a later date.

It was a crass and tone-deaf attempt on our part to signal awareness.

Lesson learned. Subsequent attempts to engage sincerely were also met with derision, so I'm not sure anything could have ever been done that wouldn't have been met similarly.
Building a space craft quickly is in fact more realistic because you're not operating in the conventional flight market which has extremely high requirements and heavy regulation for safety.

If a space rocket blows up, including passengers, it's okay, part of the business - everyone knows space flight is high risk. If a commercial flight crashes, that is simply not acceptable.
As someone who has to work in both for work, I understand your sentiment. I much prefer your world.

I think the difference is that in Desktop/Mobile, whatever crap has stuck to the wall for years - you must use because you don't have a choice. And usually this crap is fairly well documented because it is your only choice.

In the Web World, there is a bunch of crap thrown at the wall (every day) and you have no idea what will stick and what will slide off each year.

Maybe a poor metaphor, but just kind of how I feel on some days.

Also, SpaceX is fine with having their vehicles occasionally explode. Which is considered par for the course in spaceflight circles, but not so much in jet travel.

I had already completed my math degree when I took the course, but I felt like there was not very much math required at all. You could just take the mathematical concepts he told you about as facts and move on. You didn't ever have to worry about having to derive those concepts from scratch later or anything like that.

I'll err on the side of caution and say you should probably have a solid grasp on algebra.
"but this is Hacker News."

I don't think I understand what that means. HN has always had a rich mixture of VC-seeking entrepreneurs, spare-time hackers, software hackers, hardware hackers, greyhair DB analysts, academics and PhD students, and curious 9-5 bystanders.

The community certainly provides good publicity for YC, but I never got the impression that pg intended this board to be exclusively a place to talk about VC investment or what it takes to get it. Exactly the opposite in fact, a wide diversity of experience and subjects was (and still is) encouraged.

I have no way to gauge, but I'll bet HN members interested in surfing VC-infested waters are a small minority of the people here. This article is right on point for a large number in this community.
They picked the one city pair already served well by rail??? One where there will be substantial time lost to immigration queues anyway, thus reducing the relative benefit of high speed travel?

It's the bit where it says 'is it used in conjunction with a hypervisor?'. That's how we define the use cases that count as defendable against malicious guests.

This covers more than just the TCG cpu emulation because it also means that any device model that can only be used with an emulated CPU is also out of scope for CVEs and hasn't been audited to confirm it has no VM-escape bugs. So the internal documentation of TCG itself isn't really the right place to document this I think.
Based on the inputs of time and initial biomass, yes, roughly.

Burning petroleum or coal is much more like burning diamonds than wood, economically and geologically. And if you look at the history of how we got here, especially the law and economics, the scientific basis for those assumptions was tremendously flawed.

It seems to me that most stores either sell counterfeit products, or all mid-tier brands have given up and sell low-tier products for the same old prices. It's no surprise then that consumers are flocking to low-price, low-tier stores: at least they know what they get.

It's good to see YCombinator funding some ambitious and really hard projects, but I'll believe the "in a decade" when I see it. Even if a decade's worth of battery technology improvements allows it to get off the ground, there's still a lot of painful certification processes to work through (and certification authorities likely to be less-receptive than average due to it being a new entity and having less commonality with previous generation aircraft)

A little surprised they seem to be going after the ultracompetitive A320/737 market rather than the shorter-haul, lower-speed, turboprop market as well (closer to their starting point, less competition, even more fuel price-sensitive, airline customers less conservative etc.)

I live in a country which is fighting off an external aggression for the last several years, and here "making killing machines" for defence contractors is a noble thing because you are literally saving lives with your work. And it's close to volunteering because you won't get paid proper money on such a job (because the money paid to you would likely be donated by other citizens anyway).
My experience (sample size of 1) is that long-lived monoliths tend not to evolve along "well-designed" lines, but rather along "what can I possibly do to get this to work in the time I have?" lines. Further, it's an impossible hurdle to schedule big dig to make substantial architectural improvements on a large monolith, so refactorings and improvements tend to be shallow and localized.

A decade later, and you have a lot of business logic in stored procedures in your database and now hear grumbling from coders who don't know or don't want to learn SQL. (And, to be fair, it does make it harder to scale the engineering team if everyone needs to be proficient at SQL.)

Neither availability nor technical scaling concerns were the reason we started to transition away from our monolith. We were regularly hitting 4 nines of availability (measured by "orders coming in") and had scaled to well over $1BB in revenue essentially on a single database for most of the site functionality. Above average engineers and ops, and way above average DBA team was key to making that happen.
