The air breathing operates upto mach 5.14 and 28km (which is higher and faster than an SR71).

That would be about 5500km/h. The first stage of a falcoln 9 on the recent flight was 6,600kph and 91km high, so not a direct comparison but fairly close.

Re-entry heat shields is still going to be a problem if it goes to orbital velocity of 27kkph for something that's reusable.

A really nice use of UML sequence diagrams!

A little off topic, but even though I wrote a UML book a long while ago, I have more or less stopped using hand written UML except for sequence diagrams. Any class diagrams I put in documentation are auto-generated from source code.
that's absolutely true. Well, not the ebola part.

It's one of the examples I use to demonstrate differences between Western and Eastern culture:

in the West we would only wear a mask if we were worried about being infected with other people's germs.

In the East they wear a mask to indicate that they are unwell and to stop other people from being infected with their germs.
There are different types of veneers. Most cosmetic veneers are just thin layers glued onto the tooth, and often leave most or all of the underlying tooth intact. Full veneer crowns involve grinding it down.

I have cosmetic veneers on two teeth that were intact but looked awful, and they're just a layer of porcelain laminate glued to my real tooth. The underlying tooth was polished and filed a bit, but certainly not "ground down to little sticks"; the teeth could have been left as-is and functioned fine.

I also have several full crowns, but they were down because of decay, certainly not for cosmetic purposes. That of course does not mean that you can't do full crowns for cosmetic purposes, but it's usually a last resort before implants.

If you can't chew properly on a crown you have a bad dentist. Nature really does not work best in this case for a lot of us - two of my crowns are in place because parts of the real tooth shattered into several pieces while chewing, others because the damage eventually got so severe that there was too little left to save.

> Wiki "The economy grew between the 1950s and 1970s at one of the fastest rates in the world, changing Romania from a predominantly agricultural country into an industrialized country. Almost 30% of the population moved during this period from rural to urban areas to work in the newly-built factories."

Yup, they did do a few things well. Free primary and secondary school education, giving women access to jobs, increased urbanization, etc.

But you have to keep on thing in mind: this was communist planning and reporting. We even have jokes about it. Stuff like the production being reported as having grown 10x in one year and then people having to bring stuff from home (from last year's harvest) when being asked to hand over this year's production.

Plus, they changed the country from 90% rural and agricultural to 60%. Even in 2000 45% of the population was still working in agriculture. If you compare their results with same-period Western bloc countries, Romanian gains were lower and shorter term ones.

> Not defending him, but what I found interesting is that it is the only country that comes to my mind that actually paid its debts off without defaulting

Well, it was interesting, but it was at the cost of turning us into an autarky. You know who is/strives to be another one? North Korea. Do you know how Ceaușescu got the idea? In North Korea, after a state visit. He wanted to turn Romania into one of the world's poorest states, just so people would shower him with flowers at yearly events...

And regarding our growth numbers ("between the 1950s and 1970s"), guess when Ceaușescu visited North Korea... 1971 ;)

Thank you very much for this explanation. It reminded a bit when I read The Chrysanthemum and the Sword by Ruth Benedict. I visited Japan (and stayed with locals all the time) this last year after reading that book and I didn't see most of these rigid descriptions Ruth Benedict explained there, but I felt like they have this kind of work culture that is way different than mine in Spain.
Really sounds like you had a bad dentist. Whenever you do get around to having it fixed, don't let them get away with it.

Also note that dentistry tech advances very rapidly; a proper crown done now will be substantially better than a crown done a decade ago, and certainly a lot better than a mediocre one done a decade ago.
Just try it! It's free and quick.
I'm 53 - I can remember news stories about HOTOL when I was in high school!

Mind you - it would be fantastic to see this become a reality.
I can't speak for OP, but in my humble opinion, they don't really serve the same purpose. Jena and Marmotta are implementation of standards, while Neo4J is more of a proprietary system, and the underlying paradigm is different between triple graphs (for Jena and in a lesser dimension Marmotta) and property graphs (for most graph databases, e.g Neo4J, Apache Tinkerpop, OrientDB...).

To make a very short summary, RDF is more concerned with the possibility to link data, so each piece of information is identified by a dereferencable URI, and can be described with an explicit model called an ontology (fancy word for a vocabulary used to describe data). On the other hand, Neo4J is more concerned with performance, but does not consider linking data accross the Web, or using an explicit schema. And for Marmotta, it is in kind of a bad place right now, the development seems a bit stalled, and the standard it implements is quite complicated compared to the majority of the problem it solves. This might evolve however, since Linked Data Platform (said standard) is now promoted by SOLID (https://solid.inrupt.com/), a new initiative by Tim Berners Lee et al. to enable a truly distributed Web.
I really hope they don’t. One, electric cooking is shit however you wrap it up. I have found a large correlation between people being okay with electric cooking in places I’ve lived and also not cooking/not knowing how to cook. That’s probably the only way electric cooking has become so prevalent in the UK. Who would want to anyway if stuck with electric?

Two, I do not want to have to wait hours for the tank to heat up again after someone takes half a minute too long in the shower.

The power just isn’t there when it comes to electric water heating. I am very glad to live in a house with a combi gas boiler right now where the whole house can have a shower on demand, straight after each other if need be.

Until we all have massive heat pumps or some other way of getting high-power heat from domestic electric, it makes complete sense to me for us to pipe gas around while most of our domestic energy usage in the UK goes to heat.
So on par with the UK? :)

I am joking but my experiences with UK Rail made Polish railways look good.

I recently had major orthognathic surgery, a two-step process: surgically-assisted rapid palatal expansion (SARPE), where your palate is basically "mobilized" and cracked down the midline to allow for expansion in adults, and then maxillomandibular advancement (MMA), which advances the entire jaw forward ~10mm. The braces should hopefully be coming off soon.

Obviously I did this for medical reasons - sleep apnea - but I do wonder if the so-called epidemic of sleep apnea could be related to the dietary changes described in this article.

Unfortunately most of the world's hydrogen is made from mixing fossil fuels with super heated steam.
That's much more an option than a segment, and many other manufacturers have served both needs with a single model (e.g. Nissan).

I think JLG's point is that many potential 3 buyers may well prefer the higher styling of the Y, and the data in the marketplace is definitely demonstrating that SUV-type models are incredibly popular.

Clearly people who need 7 seats will wait for the Y. Are people thinking about a 3 going to be put off by 7 seats? Probably not in massive numbers.
I completely agree on the acoustic isolation part though. The slats completely negate that in noisy areas even when closed.
There was a movie showing their heat exchanger test going around. It is a gas to gas (helium.) And you can pump helium at very high flow rates. Speed of sound in helium is 1000m/s after all.

That is only relevant if you expect most Model Ys to be sold as seven seaters. The point of the analysis piece was that CUVs are more popular than traditional sedans.

Their popularity, at least here in Europe, has nothing to do with their similarities to true SUVs. Instead, people buy them because they want something that looks like an SUV (or true off-roader) but they can't afford the purchase or running costs. The Nissan Qashqai, Citroen C-Crosser, VW T-Roq etc sell well not because they have seven seat options, or whatever, but because they look sturdier/safer than their traditional rivals.

That's the point of the Monday Note piece: the market has shown that there's strong demand for crossover cars and, in the author's opinion, buyers might wait for their prefered format of car rather than settle for the sedan today.

It's anti-centralization and pro-meritocracy. If anything, it's pro-tech.
There are a lot of people right now who have built great tech and real innovation which is being ignored completely
because some financially successful firms with massive network effects are attracting all the talent and focusing it towards their lesser technical goals, slow processes and inferior tech.

For example, AirBnB has thousands of employees and yet barely anything changed in their service in the past few years.
The engineers who work there are not productive. Their main skill is in creating highly complex solutions whilst taking minimal risks; that's not what engineering is about.
The same goes for almost all major software companies.
Each engineer does very little work and contributes very little towards real innovation. These big network effects are holding tech back. They are draining cash away from pure tech and focusing it on social networks.
But then it becomes ambiguous whether you're talking about fertilising the tree, or the tree fertilising something else. Perhaps self fertilising? But that sounds like reproduction.

And that's assuming we're living in a world where you can petition the World English Language Governing Body to make the necessary changes to the language.

But for better or worse that body doesn't exist so we are stuck with what we've got, and at the moment people talk about nitrogen fixing plants, so if you want to communicate with people, you need to use those terms.

That isn't clickbait, that's just making sure a headline doesn't turn into an off topic essay.

Interesting, thanks? You seem knowledgeble on the subject, what's your take on the commercial and technical viability of this tech in general and REL's abilities to execute more specifically in the case the tech is viable.
True, but this is not impossible, even with 19m people. It's doable, smaller countries have done it. It's a matter of willpower.
Yea, not worth unless it gets somehow into one of your specialized subreddits.

I was going to ask how Redacted compares to Waffles, but it looks like Waffles is almost a decade older, which likely translates to the number of releases pretty well.

Though, Waffles had a sizeable fall in activity in the last couple years—notably coinciding with the closure of What. One would think that What-expats would bring in fresh blood.

Hi everyone, my name is Guillaume.

Over the past 8 months or so I have been working on this browser extension.

So far, we have been receiving quite positive feedback.

I'd love to hear what the Hacker News community thinks.
Implementation-wise, with message passing the operation to be performed is sent as a parameter to a message handler. A method call, on the other hand, is simply the invocation of a subroutine stored in a record field (a function pointer). The following article provides some examples in the Oberon programming language which I found clarifying:

Funny, for me NeXT pretty much was Smalltalk + Mac + Unix.

And there were mechanisms for an OpenDoc-like system of embedded content (maybe more like OLE). While the rough idea of OpenDoc was and is appealing, I don't think that version of the idea is actually tenable.

Alas, since it was killed, it sort of lives on and occupies that space as an ideal version of the rough idea, rather than as an artefact that can be criticised and improved upon.
I wonder if this technology will ever be viable for commercial flights in the future. What the safety procedures would look like at that speed.
As someone who isn't really a car person, can you explain what makes the Model Y an "SUV-type" model? From where I'm sitting it looks just like any other midsized family car without any particular "sport utility".
I was looking at it from the narrow view that it was to do A (the papering over), and it did not do that (fully).

On second thought, it’s more a systems engineering issue not to take that case into account. Software engineering doesn’t get off scot free though, as they are an important voice.

With the presumably tight engineering controls that are practised, I can speculate that it may have fallen into “the pilot disables and takes over control” branch. The gap would then be that they did not think that the airlines would be given the option to “not” install the sensor failure warning.
Not 100% certain, but I think the killer feature is the ability to manage your own data while exposing semantic representations that external apps can interact with.

The guiding idea behind RDF was (at one point) that users manage their own data while apps they give permission to can use that data.

The Rolls engines designed for HOTOL were meant to do the same, by a different method. They were going to use the hydrogen fuel to operate the intake heat exchangers. The engine then burnt hot hydrogen. Any excess was used as reheat injected into the exhaust.

> The 0.6 claim meant that the MCAS system qualified for a max risk of hazardous (people injured), not not catastrophic (ie plane loss).

My god. So that is why they only used one AOA sensor rather than comparing both -- and offlining MCAS if they disagree -- they thought it was DAL C (maybe because 0.6 degrees of stab trim likely can be countered with elevator deflection) and not DAL A.

And since there was no annunciator on the flight deck to indicate that MCAS was kicking in, the flight crew on the incident aircraft weren't able to diagnose the problem (since it didn't act like a traditional trim runaway) and do the appropriate actions to disable the electric trim control before it was too late.

Horrific.
Matrix is the perfect example of xkcd 927 - https://xkcd.com/927/

They built something like XMPP, just a bit different. What they got is more fragmentation in the space of free messaging. None of the justifications they have how their approach is different justifies the costs of additional fragmentation they create.

This is super frustrating, people don't seem to have an understanding what the costs of incompatibilities are. You can also observe pretty much the same at the micro level of within XMPP and encryption standards, where everyone seems to think the solution is yet another encryption standard instead of having just one.
I just hope they've got the IP well locked down. Bound to be lots of envious eyes on this tech!
There are different kind of ALS diseases. ALS is not well defined, there are no quick tests or biomarkers. And once it is diagnosed (usually 2 years after the onset) the patient lives only two years (but that can vary much).

From a practical point of view there are roughly 50% of patients (pALS) that carry a mutation on SOD1 gene and most of the rest have TDP-43 bodies inclusions in their neuron's cytoplasm. Abnormal TDP-43 is also seen in other CNS diseases such as Alzheimer.

This article tells that abnormal TDP-43 stems from ADAR2 downregulation and Calpain abnormal activity.

ADAR protein is a RNA-binding protein, which functions in RNA-editing through post-transcriptional modification of mRNA transcripts by changing the nucleotide content of the RNA. So affected motor neurons bearing TDP-43 pathology invariably exhibit failure in RNA editing at the GluA2 glutamine/arginine (Q/R) site due to down-regulation of adenosine deaminase acting on RNA 2 (ADAR2).

The authors tell that exaggerated Ca2+ influx through the abnormal AMPA receptors overactivates calpain, a Ca2+-dependent protease, that cleaves TDP-43 into aggregation-prone fragments, which serve as seeds for TDP-43 pathology.

I believe this publication is novel and important in the ALS field, any comment?
For women it might be easier if the LEDs are built into a hair accessory like a hairband. Less of a social stigma than a baseball cap. Glasses work too of course.

My common sense says that tech is not viable, but reality shows otherwise. Thus, I can't tell much about it from my common sense. The company must be staffed by much more competent engineers in their domain than I am.

The most tricky parts in my view are the pre-cooler just for the giant mass flow and temperature difference, and the helium/lh2 heat exchanger, but those two seem to been done. O_O

How to live without Google (2017)
You need to realize this problem before it is too late. If there is full trim down when you realize it there might not be enough room left to offload the stabilizer and trim back (manually, no less). Afaik if you cut off stab trim you can only trim back manually by moving the trim wheels.

I'd not be surprised if there will be another problem with MCAS detected with the ET flight where the pilots had effectively no chance despite knowing of the Lion air crash.

It is highly distressful and should give us all a big scare, when we arrived a point where you can expressly call for censorship and direct it solely to the political view opposed to yours.

If you were calling for censorship against both far right and far left, sure, I would probably disagree but would concede it was a coherence point of view.

But calling for censorship solely against one side, makes someone by definition a totalitarian.
