Yes, that tradeoff always exists. There are always edge cases. The pilot will always need specific 'additional' information about the plane to avoid crashing.

The choice to make is how difficult you will allow features to be, and how many difficult features you will add.

The answer has to be at least moderately high to get the plane off the ground. If it's too high then you have a bunch of deaths.

It's okay to say Boeing went too far on the scale, but to say they never should have been on the scale is misguided. Intelligence of the operator has to cover for certain aspects of the design.

That happened with my Macbook Pro w/ touchbar.

There was an issue with the graphics, and it initially booted into an assistive mode for first-time setup, and I wondered how a visually-impaired person would use the touchbar.

Of course it applies!

Human drivers are reliable in the presence of other, unreliable drivers. We deal with this kind of uncertainty every time we get behind the wheel.

It's not a stretch to say that we should expect at least that much from automated driving.
For the sake of argument let’s say they’re not perfect but better than human drivers, is that good enough?

Technology is inherently dangerous, but if everything that could kill someone had been held back we’d still be workshopping fire.
Echoing this sentiment of:

Motivated real world exposure > real world exposure > motivated self education > traditional education

As someone who mindlessly "self taught" through tutorials, then did half a bootcamp, then did a MSCS-- none of those things were anywhere near as transformational for me as a dev than my first year as a software engineer.

But of course, building AlgoDaily has probably taught me even more than the many years of work at this point, purely because there's been a strong impetus.

The "need to know" basis is huge. I think with a strong enough "need to know", any method works.
It’s an open question whether hash functions can be used for encryption using XOR:

https://crypto.stackexchange.com/questions/35809/whats-wrong...

Here is a basic explanation:

Note however that you would need a nonce / salt transmitted with each message because otherwise decrypting messages encrypted with the same key would just be as easy as XORing them!
That's a rather emotive argument.

Do you have any evidence to back it up, that reducing the air travel and other extravagances wouldn't be sufficient, but that we need to give up daily pleasures?

To me, it sounds like restricting drinking water to fight the drought in California: useless, gesture actions which target the daily lives of people, causing annoyance -- while allowing almond farmers (and others) to continue the real problem, without challenge.

If climate change is actually a serious problem (and I think it is), then its time for people to stop promoting emotive witch-doctor solutions (such as restricting drinking water in restaurants to fight a drought) and start taking a serious, data-driven look at causes.

Just one example: cruise ships for Carnival alone — not to even mention all the other cruise lines — pollute 10 times more than all the cars in Europe combined [1]. I’ve seen plenty of thinkpieces about not eating meat, but approximately zero about not taking cruises. Curious!

Zero mention of rare earth metals in conjunction with PV, as expected. Thanks for agreeing with me.

Alibaba CEO Daniel Zhang: “Data Is the Petroleum, Computing Power Is the Engine”
Given the price/performance characteristics of electromechanical relay computers, he was probably about right. The introduction of vacuum tube electronic logic, subsequently replaced by discrete transistors, and the integrated circuit logic changed the price/performance ratio by several orders of magnitude. There's the old joke about how your 1940s car would now go a million miles an hour and several million miles on a tank of gas if it had improved like computers. But we know it is a joke because physics sets bounds on the energy need to move a 1.5 ton mass, while the bounds on the energy to operate a logic gate are much lower. The same is true for spaceflight, where the formulas for rocket propelled vehicles are well understood.
Carrying 9 passengers 1040 km at 440 km/h is quite a lot different than carrying 180 passengers 6150 km at 840 km/h (Airbus A320). Because batteries do not get lighter as you discharge them (fuel tanks do), simply adding more batteries gets you rapidly diminishing returns. Short range electric aircraft already exist, but transcontinental flights are likely out of reach. And if you are only traveling 1040 km, wouldn't you be better off taking a train anyway?
But then that system would have to delete your face too! Great, now the only solution left for the robots is to kill all humans...
One interesting bit is that the whistleblower law was changed very recently[1] to allow hearsay (not fist person account) in a complaint. Some people (obviously biased) are claiming the complainant had assistance composing the complaint.

Guess we’ll find out what it’s all about soon enough.

You can ignore that user's comments. It's kind of like the venom that Christopher Alexander has gotten over the years. This book is a classic for a reason.

Also, everyone focuses on his sendup of architectural failings, which is the beginning of the book, setting up the context for the rest. The rest is a really useful model for how to think about vernacular architecture over time, as well as an excellent read.
nope sorry. Decision is on another table. More like if we want to share our piece of Pie with China/India population. What do you think will happen if their income increases with 50%? Biological food? Gender Neutral clothing? No, just same way of consuming we did for the past 50 years. Each gram you are going to save is compensated by kilos that their side.

the only think we still can do is heavily putting tariffs on their services/good in order to increase our standards of living unless we want to come on equal par

> Most Popular Instant Messengers 1997 - 2019

WhatsApp has approx. 2 billion users. The beginning of that video starts out with messengers (not including things like IRC and email) that have a few million.

This is just the Eternal September effect.

You and I can just crack out nginx and host a site. The author of this post didn't even do that; what hope is there for the rest?

An instant messenger, even a secure one, needs a proper marketing budget in order to succeed out in the real world. It doesn't just need to be superior - it needs to be _advertised_.
On a different platform, these "friendly" types can be larger, typically 2 or 4 times larger which can be devastating for performance, or smaller, leading to overflow. They are only "usable" if you restrict yourself on one version, of one compiler, on one hardware platform.
Poor people aren't going to like that very much...
But that performs very poorly on all architectures.
Make sure you get through the initial description of the problems with contemporary architecture that led the book to be written and get to the meat of the matter: how to think about buildings over time.

Also, the book this comes from is wonderful.
> So subpixel-AA is a really neat hack that can significantly improve text legibility, great! But, sadly, it's also a huge pain in the neck!

When playing around with FreeType's ftview demo program, text rendered with an OTF/CFF font using the Adobe CFF renderer with stem darkening enabled actually looks pretty good with grayscale rendering. Subpixel rendering is not strictly necessary.

> https://gankra.github.io/blah/text-hates-you/#aa-breaks-glyp...

I think the author mixes up two concepts here, hinting and subpixel positioning.

A TrueType font can change stuff around on the x and y-axis. Applying hinting on the x-axis messes with your layouting and prevents subpixel positioning on the x-axis. What you do is apply hinting on the y-axis only (FreeType calls this slight hinting, DirectWrite more or less does this -- not quite, but close enough) so you are free to shift glyphs around on the x-axis. This helps with displaying text with a more even texture on LoDPI screens. On *nixes, Chrome does this, Firefox doesn't.

Making orbit is a single hard step; raising orbit, which is all that making it to the moon requires, can be done more gradually (with low-thrust/high-efficiency engines, on-orbit resupply, etc).

So if you can get off the planet you can get anywhere... but that doesn't mean cost-effectively. If your planet is such that it takes a Saturn V to launch a cubesat, it may simply cost too much to make it to the Moon.
Actually, the article's point is that halting every combustion-engine automobile, boat, plane, and train forever would do less to combat global warming than a genocide of all cows and pigs.
Given that the whistleblower complaint was written by a law firm I would hope they know how to write.
In Britain the concentration of wealth and opportunity in London and the SE is a fundamental driver. If Government were to focus on creating alternative centres of wealth generation the vast stock of infrastructure that surround some of the urban centres in England could be unlocked. For example within 40km of Manchester there is Bolton, Preston, Blackburn, St Helens, Wigan, Halifax, Warrington, Macclesfield. All of these are substantial urban centres in their own right with working infrastructures including schools, hospitals, parks, leisure centres, shopping, residential districts and so on. None of them are economically exploited at this time. Similar pictures exist for the northeast.
No, but I produce twice more when I'm at home rather than in the office.
Just because biofuel production is not currently done responsibly doesn't mean it can never be. The same sustainable organic farming techniques that are used to grow food crops can be used to grow fuel crops, and should be. And don't forget that most biodiesel is currently made from waste products like used cooking oil.
Eat as much meat as you want, just leave away what you are eating out of habit and not because you actually want. This will go a long way already. Since you are not cutting down the meat which you actually want to eat, it does not feel like a sacrifice.

Works well for me.
How long does it take you to code a program if you are being bogged down by such simple problems? Use ints and do bounds checking when it's necessary to do so. Is every single bucket of information a reinvention of types?
Weird. The site is served by cloudflare and backed by an s3 bucket. Totally static. You shouldn't get forbidden unless cloudflare or your isp are doing something odd.

One key question is whether symbolic AI is the right model of the world. It underperforms vector based AI on many specific tasks. But human experts heavily reply on it to communicate with each other. If symbolic AI is not the right model, P vs NP problem might be just irrelevant. Human philosophy is full of craps. We will lose a lot of beliefs.
Elon will be right, we will abandon human languages, and connect through a cable in the brain. Everyone will relearn every thing from NN.

If symbolic AI is the right model, but difficult to build algorithmically. Vector based model just help to make it faster and better. Then we humans are fine. We simply proxy the lower level optimization to AI. Our functionalities will be shifted just like what happened when engine was invented hundreds of years ago.

> Worse, the compiler is entitled to use saturation arithmetic if you've assumed wrapping.

C89 (draft[1], because the actual spec is not public) section 3.1.2.5 states:

> ... a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting unsigned integer type.

So, unless I'm misunderstanding, the compiler is not entitled to use saturation arithmetic on unsigned integers.

Dunno where you went to school (liberal arts college?) but most programs are NOT like that, my degree required 30+ hours a week on assignments outside of class.

I found the material and tests straightforward but you absolutely needed to put in significant time to complete the assignments.

At this point, when I see libraries like this all I can think is ”oh good, my compile times aren’t long enough, lets make EVERY INTEGER a template”.

Also, while I can reasonably beliveve that most of the overhead goes away at -O2 or -O3, this has to just trash performance for debug builds, which is not unimportant.
The article was a bit light on hard values, does anyone have good sources? Googling, main pages which come up seem to indicate the impact is only ~15% of total GHG emissions [1][2].

In the twitter thread for the second incident the owner claims he commanded a stop (released the button) prior to the event but is uncertain as to whether the car stopped itself. So that makes at least three people who thought the summon feature was not going to yield to cross traffic.

true, but the behavior of unsigned integers is defined such that they can't overflow. the "wrapping" behavior of unsigned ints is defined: you get the arithmetic result modulo the max value for that width.

Incidentally, if you are in this area, I recommend seeing the nearby prehistoric cave paintings of La Grotte du Pech Merle (the cave itself is also interesting). Unlike some of the other caves, what you see is original (not a reproduction), multi-colored, and tickets can be purchased well in advance. For me, it was an experience that could not be compared to anything else -- being there provided a new view of humanity.
You're being down voted but you're making an extremely important point. It's very, very difficult to convince people to reduce their quality of life because something bad is going to happen in the future to people who may or may not be them. You see this all over the place in other domains such as diet (people know they should eat less but don't), exercise (people don't do it), personal finance (people don't save), alcohol and drug use (people don't stop), medication compliance (people can't be bothered to take their meds), security (people can't be bothered to do best practice), etc; and those are problems that directly affect them with shorter time horizons. You're fighting human nature, and you're going to lose. Further, you have a collective action problem where no one is going to act because they don't want to be the person who has to reduce QOL while other people don't. I firmly believe that people will not get onboard with reduction of consumption en masse and that the only way to solve the problem of climate change is to innovate our way out of the problems while maintaining analogous QOL.

I applaud the general HN community for taking a stand against the problem and making sacrifices, but the reality is that most other people won't, and I think we should have that discussion.

All countries accept much bigger death tolls. Just the radioactivity released to air from burning coal is much bigger than Fukushima. Never mind that Coal causes almost all deaths by other means than radiation.

Consider this:

600 PBq - Upper limit of radioactivity released from Fukushima accident. Actual may be half of that.

> No country will ever accept more than one of those.

I think you really have to be oblivious to the current state of affairs on the road not to understand what he's getting at. As someone riding a bicycle on city streets, he is absolutely right. It's not safe out there right now. Even the current safety statistics are skewed by the scarcity of non-car road users in most places and the amount of advanced machinery in a car dedicated to keeping people (the ones inside the car, at least) alive in a serious accident.
Given that the ICIG and DNI both found the whistleblower credible, I don’t really know how to interpret attempts to dismiss it for being a secondhand account as anything other than entirely partisan.
