This 'solves' the problem of dilution, but it does not address the issue of following the flow of tainted crypto-cash, because the root cause of that problem is that bitcoin do not have identities (they are bosons, not fermions?) This 'solution' is just one of several similar possible schemes that arbitrarily assign a provenance to each atomic unit of the currency, and is not fundamentally more sound than any other.

Any scheme like this is pointless without a mechanism to sanction the use of 'bad' bitcoin, and belongs in the realm of cryptocurrency regulation, not blockchain mechanics. A scheme something like this does exist for banknotes, in that if you are found to have a counterfeit bill, it will be confiscated. The only reason this does not have a stifling effect on the use of paper money is that the probability of this happening to you is slight.
Don't think anyone who moved would be wanting to move back just because Apple now supports a GPU dongle.
And CalTrans for not fixing the crash attenuator (the man did not die instantly, so if the crash attenuator had not been removed, he likely would've survived.) And for making a confusing lane-like path right into the crash site. https://imgur.com/a/iMY1x

I mean, the crash attenuator had recently been used up, but the dangerous line situation that led to the crash which destroyed the attenuator had not been fixed.
I'm amazed that the barrier doesn't have yellow reflective striping or any of those sand barrel thingies.
In this case though the core innovation actually happened pre-facebook. Post facebook it got more polish/tweaking/multi-threading etc. but I don't recall any breakthrough kind of change.
Ask HN: Which OLAP do you use in 2018?
Previously, there was only Redshift and BigQuery. Now, there are more Columnstores. New products like Snowflake, TimeseriesDB, ClickHouse. Which one are you using and why?
IMHO, they need to get autopilot at least an order of magnitude better than human drivers statistically, before releasing this tech, because this sort of news is extremely bad public-perception-wise.
I don’t think it’s reasonable to expect a Tesla driver to always have his hands on the wheel during autopilot
No, I wrote it myself. I figured out how it worked from reading the C standard.
It can be this bad, but it's not very common.

Usually it happens in a job with fixed hours. Are you opening up the store in the morning? You'd better be there on time.
"Autopilots performance is unrelated to navigation"

Tesla is mincing words.
Tesla Says Crashed Vehicle Had Been on Autopilot Before Fatal Accident
> You're really doubling down on the "You don't agree with me so you must not have read it" angle?

No, I'm doubling down on the "you missed the relevant and interesting parts of the memo" angle.
I can confirm Bloomberg does this, u/quackware is correct. I went through the program myself recently, and it's actually a very nice dive into a unique full stack -- and because you take the training with a large group of peers, it's a good way to network as the company/make friends in a new location, especially if you're fresh out of a grad or undergrad program.

I know there were some issues with the program in the past (for instance, at one point you had to maintain at least an 80% "grade" in the program or you'd be cut loose from the company) but Bloomberg has really invested in the program recently and it's much more trainee-friendly these days. Lots of emphasis on cooperation and teamwork, and even though there are some solo timed "assessments" they're about the right level of challenge, and the goal is understandable -- they're there so the trainers can get a feel for what lessons work and what lessons need fixing.

Anyway, it was invaluable to me. I can't imagine jumping straight into a dev role at a company fresh out of college.
> For Tesla, there is one fatality, including known pedestrian fatalities, every 320 million miles in vehicles equipped with Autopilot hardware. If you are driving a Tesla equipped with Autopilot hardware, you are 3.7 times less likely to be involved in a fatal accident.

That's very curious wording. The important number would seem to be "millions of miles per fatality while Autopilot is enabled", not "millions of miles per fatality in Autopilot-equipped vehicles". The way it's phrased, I wonder what part of that 3.7x multiplier is unrelated to Autopilot and is just due to the car's high safety rating in a collision, recent release (no long tail of older, less safe models contributing to the statistics), and luxury status (more likely to be driven conservatively by old rich people.)
Probably because on average they are taller than the rest of the world. If !that then idk.
They are not allowed to come home by bike now? What am I missing?
Technically tesla's statement says he was warned at some point to take control during his drive. That could have been 5 seconds into his commute, or it could have been 5 seconds before he hit the barrier. He may have taken control at that time, and then reengaged it later. He may or may not have been warned to take control before hitting the barrier.

Tesla's statement is not clear on this at all.
Interesting resource. Given that "no-cloning" [1] seems to be a fundamental property of quantum mechanics, I would expect any relevant programming language to enforce linear types i.e. "use exactly once" constraint.

Who could they be? Democrats or Chinese?
It's not clear to me whether the "several visual and one audible hands-on" happened right before the crash (6-10 seconds), or the minutes before.
Definitely a difference but there is a similarity in vectors of attack: The contact address book can be taken off the phone using the Apple SDK. Then, that data can be anywhere the developer wants to store it.

"In reality, Apple collects more information about its customers than Facebook because it offers more products and services."

Was/is all that data collection necessary?

Did they (or Microsoft) make decisions about data collection based on perceived competition from Facebook or Google.

Considering e.g. how ads were integrated into MS software products (e.g. the "free" versions of Office software that appeared a number of years ago) I think the answer is yes, at least for MS.

I believe all these companies (AAPL, MS, FB, GOOG, AMZN, a few others) react to each other and often adjust their short-term and long-term goals accordingly, even when they might be thought not to be competing.
The app review will catch some stuff but won’t be comprehensive since it relies on human judgement, right?
You can't just bury trees whole, you need to convert the cellulose and lignin into charcoal so the microbes in the soil can't break down the carbon (coverting wood to charcoal basically scrambles the carbon bond structure preventing the easy enzymatic cleavage of the cellulose polymers).

A few people have suggested doing exactly this with nitrogen fixing trees like Casuarina sp.
How's the latency when using this method? I'd imagine if you foresee your site being low usage, startup times would be quite bad. At least, on the order of seconds rather than milliseconds.
The "real functional" map/reduce/filter functions tend to be discouraged by programmers and linters too. It is becoming (has become?) an established part of the culture -- "Lambda in a `map`? Use a list comprehension instead."

I guess it's a "sheep as a lamb" thing -- "The 'functional way' is either points-free or pointless."

Maybe it's better in Rust because the method-style `x.filter().map().reduce()` lets you read left-to-right, and the "global function" `reduce(map(filter(x)))` has to be read inside-out. If there is a good reason to do Python's global function way, maybe D's UFCS can bring them the best of both worlds.
No, any money in those addresses that was there before your dirty satoshi would still be considered clean. That's one of the claimed advantages of their technique.
Because humans have agency, a quality we seriously dislike in things we create (control). If a computer woke one morning and said, I like being plugged in more consistently I'm moving to your neighbor's house we would not like that computer much, even though that might be more "intelligent" behavior from its perspective. So we basically don't allow things we engineer to have "real" intelligence because that would include qualities we don't like in our creations.
Speaking of insurance, but not self-insurance:

I'm guessing that if I buy a Tesla with autopilot, I'm not going to find any insurers who will charge me discounted rates that reflect autopilot being 10x safer.
How does Keepass not get attention? I'm pretty sure that is the most widely used password manager among professionals.

It doesn't generate as much marketing buzz on its own as a Lastpass or a 1Password does, but too many people have too much stake in their passwords for them to even consider a less secure solution solely based on marketing.
When You Start a New Job, Pay Attention to These Aspects of Company Culture
No one really knows. But I wouldn't be surprised if there's a mix - I'm sure there's some automated investigation of how much data is sent, when and what that data is.
It's not obvious to me what the relevant measurements are on the zstd side, but I'm pretty sure lz4 wins considerably where code size and RAM footprint are major considerations, as in some bootloader and embedded firmware situations.
In this situation I think the lane to the right is not the shoulder. So in a situation where there are only seconds to respond to an obstacle, there might be cars blocking the Tesla on the right.

Optimal stopping
I have a lot of respect for Tesla, but this incident convinced me not to buy one any time soon. I have children with car seats. The fires that break out with battery right under the middle makes it impossible to save someone in the driver seat, let alone in the back.

More importantly, self driving cars are not the same - Waymo has lidar, Tesla and Uber don’t (correct me if wrong). If a system is clearly struggling with the detection of still objects in the middle of a highway, on a sunny day, it cannot be trusted. If I ever bought a Tesla, I wouldn’t use autopilot unless their hardware proves reliable.
Fair enough. A clever avoidance could find developers activating some evil stuff after the review process itself, though.
If you haven't yet, I highly recommend checking out one of the old catalogs. The writing has an infectious spirit of hope and enthusiasm.
That's crazy bad. This XKCD comes to mind: https://xkcd.com/1958/

It's like they painted traffic lines to guide vehicles into barriers, and then didn't replace the attenuator after a human driver made the same mistake as the Tesla autopilot did a week later.

To be fair, a famous person wasn't involved in this crash.
He lived in Foster City and was working at Apple, so it's likely he wanted to take the 85 ramp to Cupertino.

I've seen something that said that the car was warning him to take control, but he hadn't done so. Texting, maybe?
I'm very uneasy with how much astroturfing enpass has done in the past so I will stay far away from them. Track record means a lot when dealing with such sensitive information.
I truly believe that if you can't do the job of the people below you: you're not qualified to lead them. If you can't motivate people to work harder to solve the issues that they're stumbling on: you don't deserve leadership. If you can't get your team together to coordinate their activities in a way that makes Russian ballet seem like a circus full of bears - you need to get out of the way and get someone in who can handle the machine-like precision needed to coordinate an organization and start making real headway to building the business.

I disagree that if you can't do the job of the people 'below' you, you're not qualified to lead them. When I first lead a team, I worked with people that were a lot more competent in specific areas than I ever will be. In turn, I could still learn from my 'managers', but in different areas than where I have my skills. So everybody learns from one another.

I do agree that motivation is very important. I had to think of theory X or Y. Do you distrust (X) or trust (Y) people to do their work well? These believes tend to be self-fulfilling, but can still be useful in different situations. Distrust tends to lead to a lot of control and micromanagement, which imho for knowledge workers does not work. Trust has advantages and for me leads to a better working culture, but can also lead to the issues described in the article.

I learned a lot from an online version of Harvard's Psychology 1508: The Psychology of Leadership given by Tal Ben-Shahar. If you can find it somewhere (there are some classes on youtube), highly recommended!
Well initially preferring to use a homegrown solution (like a programming language) isn’t necessarily a sign of zealotry. Dogfooding is good :)

Go just seems like a much worse match for this problem than Swift. Wrong type system, wrong compiler architecture, wrong runtime design, wrong language evolution strategy. This is in so many ways a great match for Swift.

Not exactly “intended”, but rather, for want of a better quote, the person you’ve replied to, chose Ghost In The Shell reference, based on a J.D. Salinger quote.

The “author”, meanwhile, wrote the article we’re discussing in this HN thread.
I haven’t yet... Managed to convince work to let me come in at 10-10:30am and I typically work until 6:30-7pm, or leave a bit earlier and do an extra hour or so from home at 9 or 10pm. So I still do a standard amount of hours for full-time here, just shifted back one or two hours.

Apparently your sleep cycle does slowly get earlier as you age so maybe I’ll be able to do 9am to 5:30 in a decade or so! I may go back to the doctor and try melatonin supplements or something, but as long as work’s OK with it I’m doing alright.
Amazon is almost as good as Apple & is better than Microsoft
If that's literally the best case scenario, then that's pretty damn pitiful and a gross misleading of facts using statistics. It's a shame. Let's use "AP disengage" as the equating metric to human-caused crashes and see how it stacks up.
I think you will find that people like to generalize everything to black and white so things make sense when in reality there are much more complex things at play, not to mention that humans are not designed to fit one mold. Somehow this is a commonly accepted truth when it comes to baby with “all babies are different” but when focus shifts to teens and adults we are supposed to be neatly organized into cstegories and labels. Pleeeeeeeease...

My point being, your situation is not necessary comparable to others. Case in point, as a child I had a difficult time falling asleep at night without screens. I woke up late and was always tired in the morning. You might attribute this to a number of some factors we probably don’t have time to discuss here. Now, as a teenager I was able to fall asleep like a rock on most days but was still tired the next day in class. I can’t tell ya how many times I’ve heard “that lazy guy” Label being applied to myself and others who shared this trait because imo it’s too convenient to label someone rather than trying to understand the underlying issues.

In any case, I tend to agree that school most definitely starts too early for a growing human being whose development takes place at night and specifically mostly during slee when body is at rest. Is it a surprise then that a developing body requires more sleep? Circadian cycles or not, kids should probably start school at a later time. Now, whether society can accept this and modify adult schedules around new findings is a question not easily answered. I suspect for this to happen, society as a whole will need to move away from 9-5 or at least become more remote and or flexible.

Ask HN: Any good material on getting started with dimensionality reduction?
It's interesting nobody is asking why the crash attenuator was not replaced faster.
What exactly is the typecheck macro doing here? I get that it compares the sizes of two pointer values but I don't know why and I feel like there is some C standard nuance involved here that I don't understand. Also, is the `sizeof` used to force evaluation at compile time?
I think the answer is that the path into the barrier looks just like an actual lane, and that this was enough confusion that a human driver apparently had made the same exact mistake a week earlier.

That's very troubling. If you saw the Uber crash cam on the driver it's obvious that the "responsible drivers" are completely non-responsive, on their phones, half asleep. A system that lulls the driver into a false sense of security does NOT pass responsibility to said driver.
Make sure you foster a culture of asking dumb questions. It should be clear to all of your developers that they should ASK whenever they are stuck, or don't know something, or when they need a rubber duck.

We have a "stupid questions" chat channel at work, and juniors and seniors alike are expected to use it when they need advice. If new developers see everyone putting their egos aside and asking for help, they are likely to follow suit.
This is bad for mixers.

That is, mixers work by not returning your coin, but rather someone else's coin. So if you mix stolen coin, you may get clean coin, but many others get dirty coin.

I have read that some mixers draw on freshly mined coin. But coin from users must go somewhere, right?
I found RSS feeds to be the best remedy for my accelerated bit-sized dopamine-inducing news consumption.

RSS lets me focus on what I actually want to read, makes me take long-break (instead of short bursts of Twitter updates), and gives me longer and more structured content.

I also use RSS for sharing articles, by giving the URL of your Pocket RSS feed to friends.

I'm glad that, in the age of algorithmically curated timelines, RSS still exist!

The car will drive in a straight line and coast to a stop.

In this case, it would be more like "drive in a straight line and... collide to a stop."

Perhaps braking to a stop at a reasonable rate would be the right thing to do, given that it surely should've detected it was going to hit something?

The type of == is always int, so the sizeof is sizeof(int), and the !! makes the result always be 1 (true). The entire purpose of the macro is to have the compiler warn if the types are incompatible.

Hot take: we should revive ATOM instead.

RSS and ATOM are both nearly always machine generated and machine read so this may seem trivial to argue, but for those who are interesting in seeing the difference, this is a good article http://www.intertwingly.net/wiki/pie/Rss20AndAtom10Compared

--------

When I wrote a forum software a while back, it was trivial to not only add a feed for new threads but also for new comments (per thread and board-wide). Made it very easy to monitor updates on all my devices. Most wikis have RSS/ATOM feeds for recent changes which is a great power feature for admins.

Mastodon is atom-based, I believe. Early twitter supported RSS / ATOM feeds which arguably made it easier to follow hashtags or news accounts.

Another benefit of RSS/ATOM is that you can plug them into chatbots or use them to mirror content. I would love to see syndication come back to the spotlight!
Node apps are incredibly easy to deploy to Elastic Beanstalk. For most users, the pros of Lambda are probably outweighed by the cons (even though the concept is fantastic).
"The driver had about five seconds and 150 meters of unobstructed view of the concrete divider with the crushed crash attenuator, but the vehicle logs show that no action was taken."

This seems to be trying to suggest that the driver had 6 seconds of clear driving-toward-death time to correct for the car's actions without explicitly making such a ridiculous statement (while also throwing in the crushed crash attenuator). If the car makes a quick change in direction due to an autopilot error, a driver at speed would have very little time to make an effective correction.

Depending on the system behavior, it could be akin to having a passenger reach over and yank the wheel. I'd honestly rather Tesla just said "ongoing investigation" instead of being so transparently evasive.

If you haven’t tried RSS as your main mode of information consumption in a while, you should give it a shot. I went all-in on RSS recently and it’s been great. Way more thoughtful, long form content. Smaller dose information sources (Twitter, etc.) are useful in their own way, but I’ve found that the amount of time required to create a unit of media is a pretty good reverse indicator of how likely it is to use the baser emotions to acquire and keep my attention.
IBM claims its machine learning library is 46x faster than TensorFlow
The meteor impact threat is just a few steps from being solved. The serious problem is that humans continuously desire to kill each other on large scales. That psychological flaw won't disappear just by changing planets. Previous this was only a mortal danger to the small percentage of young men fooled into dying. As of the 20th century however, species endangering percentages of the population could die in war.

Furthermore, advancing technology makes smaller and smaller groups with smaller and smaller budgets, more and more deadly. If there remains even a modest chance of a species ending war per century century, then our remaining time as a species is very short indeed.

So while they are certainly worth doing, the species can not be saved by something as simple shifting asteroid orbits or colonizing Mars. We have to solve the other much harder problem.
I used to own two. This is a great reference book and has a wide variety of interesting material, lots of interesting stories in addition to being a 'tools' catalog.
If you look at the pictures, I don't think much cutting was needed, and certainly any that might be would be nowhere near the batteries located beneath the car; the front end basically disintegrated completely from the impact.
