Glib response aside, I want a credible description of worst case scenario for nuclear disaster. The probability of such an event increases greatly if there are many plants, particularly if there are plants in nations which go into decline or plants built in highly corrupt or inept nations. So how many people die from the initial event? How much residual radiation? How far does it spread? How many people are displaced? Are food supplies effected? It sounds like you haven't really thought it through all the way. My personal belief is that people are not to be trusted with technology with such high stakes. Especially with the onset of climate catastrophe within the century ensuring the decline of our society.
I have seen 0 proof that mankind can handle the resposability that comes with this type of extreme risk but at low probability technologies. If anything. It is getting worse in that regard.

A lot of macOS seems designed this way, it took me months of using macOS daily before I learnt these little tricks, e.g. pressing option before many operations generally shows an advanced menu (advanced network connection stats, finder merge folder option etc). I'd like for there to be an option for power users where this is the default behaviour if enabled.
Firstly this is comparing autopilot to self driving; they aren’t the same thing and you are required to stay in control of the vehicle which clearly didn’t happen with this crash.

Second there is the fact that cars that are self driving will still crash at launch. I see this a bit like air travel where over time every kink in the software will be filtered out. The software will be safer than human drivers at launch so I’m not extremely concerned.

Finally, I guess, will people believe in the statistics or will they go with their beliefs. I don’t know but I’m sure this will happen in the next few years for Tesla and for non highway driving it will be extremely safe. N of one incidents (of real self driving) will probably still happen but as long as what went wrong is learnable from I think it’s acceptable.

Base 60 was used by the babylonians. They were big into astrological observations, and so I think their influence affected time and angle calculations.

The numbers 12, 60 and 360 that occur in our time and angle calculations are interestingly factorials divided by 2. (4! = 24, 5! = 120, 6! = 720).

Since larger factorials have both 2 and 4 as factors, they have 2^3 as part of their factorisation, and by the time you get to 6! you introduce another factor of 2, so it's not a big loss dropping one of those power of 2, you still have a huge range of factors and hence ease when working with fractions with these numbers.

Attempts to replace degrees with base 10 (gradians) appears to be slow on the uptake, with radians being a more natural measurement (but who wants irrational angles in everyday life) so I think we're stuck with degrees.
So you think this is not fractional reserve banking because instead of having the fractional reserve of X% beforehand they get the fractional reserve of X% right afterwards?
> If the shell was executed otherwise, then 'which $0' will tell you where it came from, because it must have come from $PATH.

Not true: you can be in a shell not in $PATH, and if you executed it from a relative path, which $0 will not find it if you cd to a different location.
Every rooftop is somewhat different. You can't just make all roofs safe.

Yes the photosites are big, but FPGAs and CIS will merge, esp for AI applications, the photosites might even directly feed into an analog first layer, or each pixel will have its own AD.

Or memory and CIS will merge, and each photosite gets its own AD and a 4 byte memory location. By having CIS sensors directly on the DRAM or PCIe bus means they could feed a DL with higher bandwidth and lower latency. Even at 20Mpix, 4 byte pixels as 120 fps, that is just under 10GB/s, it might DMA it directly into the gpu. So the other place to put a sensor is in RDMA hardware, or if it is on the PCIe bus, it could talk directly to Infiniband nics.

Imagining have a CIS device that is also a PCIe device. It could many device classes (network, memory, storage, display). It could DMA directly to a nic, or memory controller. In the os you could trap a read to a specific inode, interpose the call and return an image. No drivers necessary.

Or a NN that runs on the chip and detects objects, infers a depth map, colorizes, smooths, augments, up res, object removal, with enough compute, you could run all the kernels or a subset on every frame.

28nm might be ok for vanilla MIPI interface CIS, but it would make a lot of sense for future innovative CIS sensors to use the smallest node they can.
Julia is a dynamic language, I don't think having the rigor of a compiled language (probably the most rigorous out there) is a reasonable expectation. It would be nice to have as an external linter service, probably.

Well, it will be 3 years next month since the first open source kinetic attack by non state actors using commercial off the self drones was conducted.

Frankly, I’m surprised it has taken 3 years for them to be used for kinetic attack by exceptionally well funded narcos.

Illicit use of drones has happened and will continue to grow.
Julia enums do not equal to Rust enums. You can achieve that functionality (that a type can be one of a set of cases, type algebra in general) with subtypes. Which is fine I'd say, but there could be terser syntax for it (which is available through packages, and it's slower). Having abstract types which cannot be instantiated is also nice.
Because it feels good is my guess. Over here in europe, Germany basically did the same thing. They now have higher cost AND pollution per kwh than france, who has MUCH more nuclear.

Oh and germany often has to sell the energy for very cheap when the renewables are having a peak, and buy pretty expensively when they are having a drought.

There's also the case of the rendering completely missing that things are cliffs (even small ones). If you jump to Barbados' airport and go to the north of the island, the rendering is of gentle sloping land (and static wave imagery crashing on to the shore) - the north end of Barbados is an old reef, and it sure as heck doesn't slope gently to the sea (see [0]). Alas, I have no idea how to give feedback about this to the developers so that it can join the long list of "stuff to fix, some day".

I recommend reading "The creature from Jekyll Island". This book opened my eyes up to the question "what is money?" and it's especially relevant today, given we are living through the largest wealth transfer in human history. But it also talks about how smaller banks work, and this notion of IOUs, credit and loans.
Very cool! I was trying to get into WebRTC a couple of years ago and it was very hard to find proper information on it.

Not that I want to cast total doubt but it will take a lot of training before machines learn all the dumb crap that humans do whilst driving. What if you have a seizure whilst driving, or another self driving car from another company just went berzerk and shifts lanes for whatever insane reason? With planes its a lot simpler since its much less likely for planes to come into such close proximity typically.
> do you really need to know how big your field is to the millimetre? To the centimetre? A foot will do.

You should really read up on modern agriculture. A foot won't do nowadays, not if you want to receive any subsidies at least.
You should expect just the opposite. It’s totally plausible could make nuclear reactions fail safe if you do it right, and I think they’ve figured that out (supposedly). But there’s no way you can force thousands of different people to get up on a roof safely.
> Why can't we create a nuclear power plant in the middle of the desert

In principle we can. Dry cooling is more expensive and less efficient than using water, but technically doable.

But the plant requires personnel. Said personnel has kids, spouses etc. You end up with a small town to run the plant. And that town requires fresh water which might be hard to come by in the middle of the desert.

> Could we safely store the energy somehow and transport it or make some sort of long-distance hookup to our grids?

We could store the energy in nuclear fuel, at the amazing energy density of 80 TJ/kg. Hard to beat that, except with fusion or antimatter. :)

Anyway, long distance electricity transmission is technically doable; HVDC losses are < 3%/1000 km. But again, it costs money.

> Also anyone know why the nuclear site in San Onofre by San Diego failed?

They detected premature wear on new steam generators. In the face of stiff opposition by local state politicians, rather than fixing it they decided to decommission the entire plant.

Ask HN: The interesting case of the endless DNS propagation
One day about a year ago, I've noticed that the site www.aqadvisor.com was offline. (I could see a page saying "this domain is for sale" or something to that effect).

I posted about that on an aquarium hobbyists forum and several users replied they could still access the site, although a few others could not.

So I decided to run a search with DNS propagation checker and it seemed that the A record was propagating so I though "oh they must have just changed their IP".

The problem is, after about a year... it seems it's still "propagating"?

https://www.whatsmydns.net/#A/www.aqadvisor.com

How come that different ISPs can't agree on the value of this A record?

The authoritative ns for this domain is bizprime2.com:

host -t ns www.aqadvisor.com
www.aqadvisor.com is an alias for aqadvisor.com.
aqadvisor.com name server ns1.bizprime2.com.
aqadvisor.com name server ns2.bizprime2.com.

and that name server, interestingly, returns the "wrong" IP, meaning that if you use that IP you will see the message "this domain is for sale", not the actual website. However both Google NS and Cloudflare are returning the "right" IP, i.e. the one that actually lets you access the website.

So what's going on here exactly?

This seems really peculiar and I'm curious :-)
Several of the papers referenced, at least, use empirical evidence not based on the experimental procedure you described.

Eg https://www.microsoft.com/en-us/research/wp-content/uploads/... and https://www.inf.usi.ch/faculty/lanza/Downloads/DAmb2010c.pdf .

I think the author is not saying "more bugs are found in shorter functions" but that more defects are found in software modules with shorter functions. Hypothesized reasons for this include ""interface errors"" and ""it’s plausible that creating functions will always carry some [cognitive] overhead in itself"".

Even then, the only firm conclusion is for very small functions, at most a few lines long. Are those the same sorts of short functions you mean?

You write: "A codebase is not a static entity." And that's true. Which is why the cited paper https://www.inf.usi.ch/faculty/lanza/Downloads/DAmb2010c.pdf (for example) tracks repository changes for several open-source projects for several years, and correlates them with reported defects. That was used in the essay, eg, ""this is likely because we consider all bugs over the ~4 year period"".

My own history is that working with code bases which follow the 'functions should be only a few lines long' approach drive me batty because I can't remember all those function names which are only used once, and because many of those code bases treat instance methods as pseudo-global variables, and modify them will-nilly.

So yes, the conclusions given here agree with my personal experience, so suggest that it is a good summary of research which was reasonably well-defined.

Which is a rather different conclusion that yours, yes?

I’ve used the teloyears service a few times with results that put me in the 96-99% percentile.

It’s an interesting concept with one of the founders Dr Elizabeth Blackburn awarded the Nobel Prize for her work on telomeres.

It’s worth mentioning I’d probably question and disparage The results if they were poor :)

Apparently it’s common for poor results to lead to bad feedback and excellent results to lead to good feedback.

So be warned I’m pretty biased!

So long as it requires an internet or similar connection I think its mainly useless. I rather a self driving car that works whether Google is damned and none existent or not. That would be impressive, you download OSM or better maps and terrain details of the world and the car based on where it travels knows where you are despite not getting a GPS signal cause reasons. We should be able to do this sort of fauly tolerance in software.

Non-physicist answer:

If you switch to viewing the universe as purely a mathematical construct, all these questions will fall away. :) The notion of ontologically privileged time or even space is based on us elevating our model of the universe into objective fact for no reason. Anything that the brain would notice even in a timeless, purely mathematical universe is thus an unneeded addition purely on Occam grounds.

For instance, we may ask the question: "would my brain, if you computed its output given its inputs, output data like 'I exist, I am conscious, I notice the flow of time passing, the present moment is ontologically privileged to me'? It seems obvious that it would; that is, the mathematical answer to the question of "what does my brain output" is that sentence. But a mathematical question cannot be ontologically privileged. We see thus that these notions of ours are necessarily vacuous; any conception of 'time', 'now' and 'me' must be relative, depending purely on the surrounding mathematical/causal structure, or else not exist at all - since even if they did exist, our noticing them is not dependent on their existence, and thus Occam bids us to discard them.
Great work @dexterlang. Thanks for building it. I am already actively using it and really like it.
I'm surprised that it has taken this long for all of it. I remember reading the news several years ago about how some small drones got close to Merkel. My first worry was about assassinations. Quadcopters aren't expensive or even very difficult to make.

How do you even stop something like that?
The experience seems to be the same for us in northern Italy. When I was in high school, about 12 years ago, there was some homophobia and, even if I knew my friends would have supported me, I hesitated to come out for a long time, simply because I didn't know how to move, and it seemed a big thing. There were maybe one or two openly gay students and they were supported by some, insulted by others. A younger friend of mine, just 10 years later, was completely out and had a good high school experience as an out student.
You mean reducing meat consumption? Livestock takes up nearly 80% of global agricultural land, yet produces less than 20% of the world’s supply of calories. It would even have a big positive environmental impact.
> Smaller nations have no problem changing everything. The marginal benefit is too small for a giant to turn on a dime.

Every other nation seemed to manage it. It's just the usual American exceptionalism. There's nothing special about the USA that makes it harder to implement. There's just just a stubborn belief that there is, which becomes a self-fulfilling prophesy. A bit like all the other policy issues which the rest of the world has solved but the US still argues about.
This immediately brought to mind the immortal words of Terry Pratchett/Neil Gaiman in "Good Omens", pertaining old british money:

> It helps to understand the antique finances of the Witchfinder Army if you know the original British monetary system: Two farthings = One Ha'penny. Two ha'pennies = One Penny. Three pennies = A Thrupenny Bit. Two Thrupences = A Sixpence. Two Sixpences = One Shilling, or Bob. Two Bob = A Florin. One Florin and One Sixpence = Half a Crown. Four Half Crowns = Ten Bob Note. Two Ten Bob Notes = One Pound (or 240 pennies). One Pound and One Shilling = One Guinea.
The British resisted decimalized currency for a long time because they thought it was too complicated.
Using overwhelming numbers of small and expendable weapons is a tried and true strategy.

Reportedly[1], radar cannot reliably distinguish between trucks blocking the road, manhole covers, overhead signs, overpasses, and a lot of other stuff.

If the car stops for every radar returns that looks like something that blocks the lane, it will perform emergency brakes for ghosts all the time. The Tesla (and others) do is to ignore returns from stationary objects in certain circumstances.
