I think you've missed my point altogether. I said that limiting the authority of MCAS was going to be the real fix. You contested that they are going to read from both sensors and possibly add a third.

I pointed out that it would be highly unusual for them to cross connect the inputs as that's not normally the design of aviation systems.

You said:

> The most modern systems today use an air data inertial reference unit (ADIRU), which incorporates the best information from three pitot and static sources and provides a single set of data to both pilots.

The report said:

> The aircraft was on approach to London Gatwick when the crew was presented with
erroneous airspeed and altitude information on one of the two cockpit display systems.

These statements are clearly at odds with one another. That isn't a pedantic argument. The systems have a clear A and B system and cross connects between them are minimised.

> Keep in mind half a dozen posts ago you claimed no aircraft used triple redundancy or voting logic

I didn't claim that. I said on the 737NG the 3 inputs (actually there are 4, the additional one drives an auxiliary set of flight instruments) aren't averaged voted upon or compared. The 3 instruments simply display data taken their inputs, even when they are potentially wrong.

Technically the pilot and co-pilot IAS is compared in that it can sound a master caution if they disagree. This is a long way from automatically choosing the best air data.

Additionally, the A330 which you introduced to the conversation, has 3 independent systems. However, they however functionally they don't drive the autopilot or the pilots display based on the 'best' data. They simply display their output, unless the input source is manually changed to the hot standby.
I would argue that a business operating with the possibility of such a high-impact failure ought to bundle in safety features and redundancies as a matter of course.

If this is so common, it should be easy for you to provide a link to the javascript password hasher on a site you use. Does this site do that? Pretty sure it doesn't. But you sound very confident about this, so I'm sure you'll have no trouble finding some other site that handles its passwords this way.
Well, there's an EU election soon, blocking for a couple of weeks before that would probably suffice to change a few minds.

Another reason to use passwordless login. Just send an one-time login code via email.

That’s what my companies do and there’s no way we can leak passwords... there aren’t any!

I honestly don’t understand the point of using passwords when a website allows reset by email.
I definitely agree with this for mathematical notes. Writing LaTeX is so mechanically different from writing down actual mathematical expressions and proofs that I feel like it distracts more than it helps me absorb.

On the other hand for something like a psychology class where the material is mostly in English prose, then I feel like typing does help. Typing English is not so mechanically different than writing down English since each letter is still in a one-to-one correspondence.
It's fascinating to watch you make a point Paul Graham already discussed way back in 2009: http://www.paulgraham.com/revolution.html.

I wonder what would happen if they poured a couple of hundred billion dollars into a facebook competitor

1. Europe doesn't have "a couple hundred billion dollars" lying around; do you have any concept of how much that is? 2. Nothing would happen; by the time the project is complete, the world would have moved on. The trick is building out the next revolution, which is exactly what Europe seems to be intent on inhibiting.

To think the only organic response is mob mentality against anything Facebook is silly. This is HN. We're here to discuss technology. As much as I stay away from Facebook these days, this particular flavor of security issue has happened to the best of companies in the past year, and it's natural to discuss that and why.

To genuflect to with "I hate Facebook too" before having a rational discussion is worthless virtue signaling.
Perhaps I didn't quite phrase that as clearly as I could have. I meant to say that changing a client incompatibly is effectively forking the blockchain.

Naturally, you still have to be mindful about whether or not you want to upgrade to software you do not wish to use. Upgrading to the new version and continuing to use it was a conscious decision to continue using that branch of the chain, made by the majority.

One more time for those in the back:

v0.x > v1
Breaking changes

v1 > v2 > v3
a couple obscure breaking changes, but practically none

18 months pass

v3 > v4
New, composable design, basically a new project

v3 still maintained, 3.5 years no changes.
v4 2 years, no changes.

v4 -> v5 was supposed to be 4.4, but an internal dependency '^' got us, so best choice was version bump to prevent problems.
For what it's worth, the implications are about the same... though in practice, it would likely be ray-tracing frame by frame, then overlays... though the process in the article could be trained with very high detail models and fill in the blanks from that.

That seems, again, extraordinarily glib and unserious. You're asserting without evidence that Tesla had nothing of value in the documents stolen, but all they have to do to prevail is show that any of the trade secrets provided a competetive advantage.

So sure, their logistics are a mess in general, but if they had a great idea for, I dunno, shipping-based rolling warehouse allocation or something, and Zoox got caught doing the same thing, it's game over.
I can actually log into Facebook with a password I used on there roughly two years ago, which to me seems like a VERY bad security issue. I'm hoping they are at least fingerprinting my devices so that if someone else tries to access my account with an old password it won't let them, but still...
Ask HN: Recommendation for time serie database for ML?
Hello,

We have a system with a lot of telemetry: logs of "device use" with many log fields (positions, speeds...).

We want to make them available easily for read / write, but also for machine learning. Specifically it should be possible to extract easily some parts of logs that correspond to some specific events, a bit like "np.where(field1 = 3 and field2 = 5)".

Another challenge is that logs are messy: some values are present in some old logs and not anymore or the contrary... Or some values sometimes are constant for a whole log and it would be nice to be able to use such structure to lower the disk size.

Which database system could be both flexible enough in terms of field values / queries ? PostgreSQL / Influxdb / HAdoop / Elastic ? I have seen good reviews of all of them and I am not yet convinced of any advantage of one over the other because I guess the devil is in the details.

Thanks !
Out of use? Not in my neck of the woods.

I grepped a bunch of source code I have lying around, and I found it used in OpenSSL (3 times), the Postgres C driver, and the Snappy compressor -- the latter because it includes a complete copy of ALICE'S ADVENTURES IN WONDERLAND!
> We've already tried this, it doesn't work. Housing is valued exclusively by the value of the housing around it.

Not sure about the claim that this has been tried. Most cities where building housing is happening are having rents increase at much lower rates than cities like SF that refuse housing construction.

Moreover if we didn’t just focus on private construction and returned to pre 1980s style construction of massive public housing projects, it seems likely to me that supply and demand could start working and hold rents steady or reduce them. (E.g. something interesting I saw on this recently https://twitter.com/RottenInDenmark/status/11080317257523363... )

Instead of public housing most anti-housing activity seems to be focusing on failed policies like rent controls.

You can see an inverse of the 3D image by simply crossing your eyes until things "line up". It will appear 3D, but things that are intended to jump out at you will sink into the page instead. But that will at least give you a general idea of how it is supposed to work. Then after you get it working this way the whole "unfocus your eyes" approach will make a little more sense.
> This difficulty lowers the likelihood of government fiscal responsibility and increases the likelihood of devestating inflation.

I share this worry too, but it's not like there's currently any political appetite for fiscal responsibility. I wonder if the threat of inflation and currency volatility would actually serve as better stick, than what we currently have which is continuing to run up a massive debt which will be terrible for our children?
I don't think this is fair to sysadmins, and I don't think sysadmins deserve your low opinion. The tools are designed the way they are not to appease lowly sysadmins, but because it is a pattern:

-Define the desired state of your system in a declarative way. This requires a DSL, and some tools such as Ansible and Kubernets use YAML as that DSL.

-The configuration engine (Kubernetes, Ansible, Chef, Salt) will converge the system to the desired state in an idempotent way using the DSL.

-Many systems have mostly the same config and many systems also run in environments that are mostly similar but with some differences. It doesn't follow the DRY principle to create separate but mostly identical desired state configurations for every system/environment, so we need programming primitives and templating tools to accomplish it. It's no less valid than a web app templating HTML for instance.

It's easy to conflate "mixing programming with configuration" with "using programming to solve configuration generation."

It does not say I cannot ask for money for my code, it also does not say wanting money for my code is something bad.

The other side is that you probably will have hard time chasing people to pay you, so in essence you won't be able to get much out of it, but that is just side effect.

I can’t help but feel that in some ways, an “artistic” ad is even worse than one that doesn’t try to appeal so strongly to aestheticism for the sake of beauty. It’s somehow more deceptive and insidious to me. I don’t think the founders adhere to much of an ethical code if they are commissioned for any ads.

That's certainly true! But your GP comment wasn't substantive, and you've posted a bunch of other ones that have this same problem. We eventually ban accounts that keep doing that, so this would be good to fix. Fortunately you've also posted a bunch of fine comments, so it shouldn't be a problem.
I think the most important thing here is whether or not the person consuming the violent media has fantasies of violence. Purely anecdotal, but in my own life, I'm convinced certain types of media have pushed me over the edge from fantasy for reality. For example, ever since I was a young child, I found smoking women to be sexy. I fantasized about it in my adolescent years. Then I discovered smoking fetish pornography and that really got me going and I started to think maybe I should actually date smokers. Then I did and I started to think it might not be to badd to try smoking myself.

I doubt I would have made it this far down my current road had I never taken that initial jump from purely in my mind to consuming smoking fetish media. In other words, I think the smoking fetish media helped me take a harmless fantasy and turn it a ruinous reality. I wonder if the same could happen for other people with other (not even necessarily sexual) fantasies.
They seem to be hitting their delivery targets despite incredibly (and unpredictably) high demand.

I think we have different ideas of "hitting their delivery targets" since Tesla has missed nearly every delivery target they've ever set for themselves...not just for the Model 3 but for the S and X as well. For the Model 3, theses misses are despite having a known number of customers years in advance of actually manufacturing the car.

Tesla has also had repeated issues delivering their cars to customers. And getting exported cars out of port (one of the most straightforward logistics functions a manufacturing company can manage). They still can't get replacement parts to many of their existing customers. These are all basic logistics failures that almost every other manufacturing company (carmakers and otherwise) has no problem handling.

Exactly. Forcing companies to do things that dont make sense for them is kind of the whole point of regulations.
We need to have higher interest rates to let the market come to its sense. Then the prices will drop for both buying and renting.
That's the optimistic case (a learning process for government).

I think the pessimistic case is that foreigners+investors make convenient scapegoats, the public has reasonable demands but will fall for plans that sound good on paper and don't work, and entrenched interests ensure that the actual root causes will never be fixed.

If you think about it, if 8 households want 5 housing units, there's just no way it can be affordable to all 8. Not by paying the 8 more, not by discouraging renting or owning, not by prohibiting investment etc.

The only things I can think of that could actually solve the root cause are:

1) Build more housing

2) Increase the housing available somehow without building more (tax units that are left empty, allow renting places that weren't allowed before).

3) Decrease the demand for housing. Maybe try to drive high-paying jobs away, or try to raise the minimum wage high enough that business go under.

Otherwise I just don't see anything else that could work, without creating some special class that gets affordable housing while everyone else doesn't (maybe the lucky people win government lotteries or inherit rent controlled apartments).
The EU single market is not over-hyped - it's basically non-existent. Of the 28 member states, about 10 or so are actually worth the trouble to do business in (taking into account regulations and taxes, local language and customs, etc).

Most of the rest are more trouble than they're worth and in the best case will merely be a blip on the radar of any business big enough to move into them.
It is my understanding that YC only funds companies that have a shot at being unicorns (I am happy to be corrected here). If you are aware of this fact, and a "lifestyle" business is your goal -- is it not dishonest to accept YC money?
I'm not sure what "literally [doing] fractional reserve banking" means. Can you give me an alternative definition to the one I gave above?

Fractional reserve banking means you accept deposits, and you make loans from those deposits, and the difference between the amount you've lent out and the amount you have in deposit is called the "reserve". If you try to maintain your reserve as a "fraction" of your deposits, you're doing "fractional" "reserve" banking. What's the "literal" aspect?

You can't spend dollars that you have in the bank, not in the sense of handing someone cash. You can do money transfers to other accounts or other banks, but when you get down to how a money transfer happens (i.e. deposits with a central bank or correspondence accounts between institutions) there's no reason that you can't do that with any substance or commodity.

There's no double spend involved, because you don't have specific Bitcoins on deposit. The Bitcoins you've deposited are long gone; munged into some central wallet and lent out to depositors, with only a fraction held by the bank. When you ask to withdraw, they take that fraction and give you the amount of your withdrawal out of it, and reduce the paper balance of your account.

>Tesla has messed up on the basic logistics enough times that its clear they're not very good at logistics.

All the mistakes in the world don't matter if the final outcome is a good one. Elon Musk has already been pretty public about some of the mistakes they made and what they learned from them, is it really inconceivable that they learned from those mistakes and are on their way toward a well working logistics system?

Clearly they aren't the best in the world with this stuff, but to say that they have nothing of value at all seems over the top.

The copryight directive is about unifying copyright law and rules in the EU. It's about making it easier to offer services to all EU citizens. If the EU doesn't regulate some area, naturally countries will have different rules, making inner EU trade in that matter difficult.

The countries of the EU, including Germany, can't survive on their own in a world where there's the USA, China and India. We need a strong entity that protects european values world-wide.

Also, this isn't a new thing either. Think of Charles IV. a czech ruler of the HRE which included both today's Germany and today's Czech republic.

Here you can see a video of how they're treated now in Western Europe: locked up, zero choices for the kid, constantly locked up, isolation cells, ... the Netherlands is even worse.

Yes, it's probably better than Nazi Poland. It's still a moral disaster.

Note that while it is true that some kids have committed a crime, there's 2 big remarks to be made there:

1) only <10% have been accused of a crime at all, 90% is there "for their own protection". Doesn't save them from the isolation cells.

2) even for those 10%, they have only been accused. Youth laws do not require any kind of proof. Nor is there defense.

3) The same goes for the 90%, all there is to say the home situation is not safe is the word of one youth worker. This youth worker has never seen the child before the trial, they have only received a single document from another youth worker who is supposed to have seen the child (but often hasn't, in fact that they fail to see those children is often a reason for passing the case to the justice system in the first place: "lack of cooperation")
