That said I do agree with the premise of the article, in order to beat humans cars will need more sensors. As humans we have our two eyes behind a windshield that can be blocked by fog, heavy rain/snow, the glare from the sun, or distracted by a litany of other things.

By having multiple camera sensors in addition to things like radar, lidar and ultrasonic sensors it should be "easy" to beat humans at driving, something that the human body wasn't designed for.

I'm not sure what the dynamic is in Germany, but here (Ireland), the subtext to such demands would almost certainly be upgrading these delivery people to permanent employee status.

The way the law (much of it case law and labour court conventions) works currently is that arrangements similar to permanent employment are considered permanent employment, with all rights.
If a company wants to keep it's "contractors'" status and avoid inadvertently picking up the responsibilities of a permanent employer, they need to avoid treating them like employees. Controlling hours, workflow and such (employee freedom) falls into that category. Providing sick pay, reimbursements, holiday pay and such also fall into that category.

Again, I don't know for sure this is an issue right now in germany, but I suspect it is. Intentionally or not, agreeing to this request/demand would weaken deliveroo's case that these are not "employees." It would set up a general ruling that effectively considers the whole employment model (which is technically not employment) unlawful.

What I'm suggesting is: (1) we find a new name/category for these employees, (2) remove the defacto laws that cause contractors to default to permanent employees when/if you treat them like employees (3) legislate new rights that are relevant to this category. These must be realistic about preserving the casualness of the arrangement.
> It's also eventually they're going to hit a ceiling and be worthless once they're all mined.

There may be huge bubble, but that comment is a complete misunderstanding. Suppose all the gold in the world had been mined. Would all the existing gold become worthless? If you think about it, you'll see that just the opposite will happen. The world supply of gold (or Bitcoin) will become more valuable.

I repeat: I'm not saying that there is no bubble.

An aside: Maybe you're thinking that if no more Bitcoin is being mined, then the market can't grow or that there won't be enough Bitcoin to support more transactions. However, there's a plan for that since the original Bitcoin paper. Bitcoin is finely divisible and the idea is that people will use smaller and smaller units for a certain value.

I'd love to find a better third-party UI for git too. Or, I've found SourceTree or the GitHub app (not the latest Electron release, albeit) hard to work with when doing a lot of stuff outside the typical add/commit/push, so I've slowly ended up learning the command line over the years.

I've seen others get in situations with fussy merge conflicts or a detached HEAD and be clueless why the UI isn't working properly. I can't blame them though, since git can be complicated and a tool like SourceTree has to make things nicely-abstracted to be helpful/productive. It's hard to know what details to make explicit/simplify, and I think with git there's a lot of work we could still do.
KubeDB is a framework for writing operators for any database that support the following operational requirements:

- Create a database declaratively using TPR.

- Take one-off backups or period backups to various cloud stores, eg, S3, GCS, etc.

- Restore from backup or clone any database.

- Native integration with Prometheus for monitoring via CoreOS Prometheus Operator.

- Apply deletion lock to avoid accidental deletion of database.

- Keep track of deleted databases, cleanup prior snapshots with a single command.

- Use cli to manage databases like kubectl for Kubernetes.

Currently we include complete implementations for Postgres and ElasticSearch database.

The E language has been a vehicle for smart contract research for decades. Joe-E is a more recent incarnation of many of the same ideas, that's a secure subset of Java.
And this is why you don't want to be one of the first people riding self driving cars. Especially since there isn't even a way for you to manually inform the car about things like this.
Why? One of the central features is control over working hours.
yeh thinking about it, cars could be updated with sensory experience via the internet from various robots around the world - so long as we find a way to transform those experiences into the sensorium of the car. For example, if a robot somewhere had felt snow with its feet and legs, it could send its experience to cars and they could transform that experience into what it would feel like under their wheels (which are the feet of cars)

Shoeshine boy indicator is flashing red for me [1]. Some chaps are calling me at midnight to lure me into the last occasion to become awful rich by buying some one/das/last-coin mining licenses.

Cryptocurrencies have a future but euphoria period is usually followed by crash and purification phase - lots of money will be lost, but the proven solution will stay.

There are a couple of routes across the country, stopping roughly once per state if that. As you mentioned, it's freight with a few passenger trains sharing the tracks.

In addition to the northeast region (DC, Philly, NYC, Boston) you can do pretty well in Chicago. It's the hub of all of those routes except for the one on the US/Mexico border.
Agreed. I always thought of it more as a trade, though now that I've been in the field for a few years, I'm realizing that technical prowess is secondary to political skill. A sub par programmer with excellent political skills will be seen by the organization as more valuable, whether or not he actually is. (This isn't sour grapes, I've been on both sides of the evaluation).

The last bitcoin being mined is not automatically going to make it all worthless. If a large enough number of people accept bitcoin in exchange for goods, it will continue to have value, and the transaction fees will incentivize miners to sustain the blockchain.

Hi. Team member here. We used a simple algorithm to prevent that. We essentially got the data itself to vote on what a real command was for exactly this reason. This means that a lot of people typed "bulid" since the vote passed on that one. I don't have a count, but many rows were not included in the data since they didn't pass the minimum threshold for being a real command. Imagine you spelled "build" backwards for some reason. That would have been quite uncommon.

You toss out this pejorative description, and then in the next paragraph:

> When talking about engineering on such a critical subject, people should be way more responsible.

This is absurd. How could it ever become critical without a lot of research and development first?

I've been holding a handful of Ethereum since there was a decent dip in the price. I haven't spent much time on it and I have no good leads for program ideas yet, but if the code is buggy and I get hacked and lose my investment, that's fine. A smart contract is a project, and it could fail like any other.

Don't put your retirement savings in a smart contract right now unless you're OK with losing it all. Maybe in the future Ethereum will move beyond this phase, and maybe not. All the drama is ridiculous, everyone needs to chill out.
It was awkward at times, the visualizations were cool but didn't really help you understand what was occuring. But, given their content and also to get people not very technical excited?

> The hackernews community in general is opposed to change which is ironic given that change is ultimately what has paid / is paying for their salaries.

That would be ironic if it were true but it's simply not. If you read the threads here, the heat comes from two camps: people who are pushing The Future of Economics!!! Get Rich Quick!!! and people who actually understand economics, have enough life experience to recognize bubbles, and are asking questions which the sales guys would prefer not to answer.

There are plenty of good technical discussions about distributed trust here but they don't start from the breathless boosterism. They especially do not start from someone responding to serious criticism with “you just don't like change” rather than addressing it.

Paypal was late, inconvenient, and (probably most damning) the brand became closely associated with scary things in the minds of many - freezing accounts, not giving funds to their perceived "rightful" owners, general legal troubles that cast doubt on whether you'd get your money.

It didn't really matter that those mostly happened to people moving 5-6 figures, most of the millenials I know actively avoid paypal as a result.
But since the car itself was detected, the autonomous one couldn't accelerate even if it thought the cyclist was far.
I don't subscribe at all to the race to the bottom concept honestly.

It is senseless to believe that it is worker regulations that isn't grinding workers. When someone wants to work more than what they 40 hour work week offers, he would go into contracting and work a lot more. Our society is filled with people choosing to work more, and no-one is richer by forcing those people to work less.

Not only that, the race to the bottom you mention would not dock pay as much as you think. In fact, it would increase riches. This is related to the classical problem of confounding money with value.

Lets say you work 40 hours a week and make 1 fork an hour, and get paid 1 dollar for it. A contractor shows up and he makes 1 fork an hour and works 60 hours a week. The new influx of 60 forks will drop the price of forks, and hence you will be paid less per fork you produce: but the entire system now has 100 forks. You will be paid less but you can buy more forks with the lesser pay. In a real world example, you would lose money, because your entire income is devoted to forks but not your expenditures: but this effect happens with almost anything that is produceds and requires labor. So basically advocating for the restrictions in name of pay, is advocating for higher nominal salaries for less goods.
AFAIK:

- ID3, CART, C4.5, and C5 are all conceptually equivalent "recursive partitioning" algorithms, and CART is sometimes used as a catch-all term instead of the phrase "recursive partitioning".

- MARS requires two passes over the data

- CART is "dumber" than CHAID, which could be seen as a benefit for "high-volume" ensembles like RFs and GBMs. One blogger writes that CHAID is a better explanatory/exploratory tool, while CART is a better prediction tool: http://www.bzst.com/2006/10/classification-trees-cart-vs-cha...

Some other comparisons:

https://stats.stackexchange.com/a/61245/36229

https://stackoverflow.com/q/9979461/2954547

So the answer is that CART specifically isn't used everywhere. Recursive partitioning is used everywhere, mostly because it is simple.
People who prefer their racing games more competitive wish that the most popular racing game was more competitive - but the reason Mario Kart is more popular than the serious simulation-type racing games is precisely because it's less competitive than those games.

Wishing other people liked the games you like is reasonable (though futile), but wishing the games other people like were more like the games you like is putting the cart before the horse.

I am in the odd position of agreeing with you and also thinking they deserved the patent and everything they could get from it. It was not a trivial achievement and involved a number of unique innovations and challenges to the published wisdom.

>I'm probably the type of investor whom people will point to as an example of an ethereum bubble (someone who knows little of the technicals behind ethereum, but is in it 'for a quick buck').

I always see "traditional" investors point to this and say "How could you possibly invest money into something you don't fully understand?"

I'm personally not invested in crypto at the moment but I can understand the draw- my response is this: When you look through your 401k, how many of those companies are even recognizable? If I were to ask extremely basic questions about any of their financials, could that person speak to them? The answer is almost unanimously "No", but it's completely accepted (beyond accepted really, it's pushed on you) to invest into companies that people don't fully understand, yet shamed if someone takes a gamble on crypto.

"Subjective" how exactly? There are surely some variations, but if this is about "my wallet has feelings too" morality, that would be all the more reason we'd need an (enforceable) code of ethics.
Absolutely, I wish people would call it out as a Ponzi scheme more.

A good example is if ETH or some other ccy takes off and BTC withers. What is a BTC worth? nothing. But people are buying it because it'll be worth more in the future. That is the definition of a bubble. Given that the original owners make the money from new entrants - that is the definition of a pyramid scheme.

So that's the difference, here, that exculpates Facebook? That they don't put their analytics code in PHP or React? Granted, Facebook doesn't put analytics code in those products, but almost every web programmer in the world happily embeds Facebook's JS blob/web bug in almost every single site on the planet to track every single click, by Facebook users or not, which can be tied back to at least a shadow profile in the mothership. That's cool? If so: Got it.

I can see the distinction you're making, but, IMO, it's splitting hairs. Either tracking users activity, by the simple act of their use of your product, is morally acceptable, or it's not. To me, this seems like this exact same thing.
