It's always going to take a few years.

The global fleet is about 2 billion passenger and commercial vehicles, and the global yearly production is about 100 million. So even if all new cars sold from now are electric, it will take 20 years.

But who knows what kind of autonomous vehicles and other innovations we'll have in 20 years. Buckle up :)
I fear he might have thought to get away with it and jump start a career or something. That would make it pretty sad and pathetic.
Well, that is the question which matters, whether or not current prices reflect the costs. I don’t see that saying “Occam’s Razor” answers the question, it needs to be proven or disproven through evidence.
If my memory is correct it was something like "low quality apps are not allowed on the appstore" ... Even if I didn't submitted an update since months and everything was running smoothly with 200k happy monthly users and very high review ratings...
That’s a lazy comparison. The only meaningful choice you have with Uber is when to drive.

A better comparison would be a general contractor in your city. You can build for yourself, for others on spec, custom per customer, tract homes, etc. The rules for where and how you can build are clearly laid out in advance in the building code. You’ll need inspections and sign-offs from the building dept that you’re following the building code. It’s sometimes annoying, and occasionally unfair. But if you want to build in their jurisdiction, you play by their rules. You’re welcome to go build in the middle of nowhere where building codes are lax or non-existent, but guess what, there are no customers there.

Yes, it is the "Family-wise error rate". You need to perform "correction for multiple tests".

The simplest, most conservative form is Bonferroni correction [1], where you just divide the required significance threshold by the number of tests you perform. In your example, if you required significance at the 99% level (1% chance a false positive, or "Type I error"), then for 100 datasets, each individual one would require significance at the 99.99% level (0.01% false positives for each data set). (99.99%)^100 = 99.005%. This does not require any assumptions about the independence of the tests. Independent tests are the worst case, so this over-corrects if there is actual correlation between the measurements.

There are other, more complicated correction methods that do not give up as much statistical power (i.e., produce fewer false negatives), but that may require making more assumptions.

I'm currently using it for creating specific components for two customer projects. With Java, JavaScript, TypeScript and Ruby (for scripts) being my usual go-to languages, I'm not a huge fan of PHP but I'd say PHP 7 fares quite well.

It's reasonably fast. Though not part of the core language, PHPUnit is really good, as is the PHP support in IntelliJ IDEA (or PhpStorm, JetBrains' dedicated PHP offering).

If PHP is your main language or if for some reason PHP is required by your environment (e.g. if the target platform for your software are run-of-the-mill virtual servers) then PHP 7 absolutely is a good choice for new projects.
One day (1994) during AP CompSci, my friend was looking for ways to bypass the cheap Mac System 7 lockdown software ("Mac Control" by BDW Software). He found the fill that changed during password changes, and was astonished to find it was the same length as the password. (N character password -> N byte file)

Me: That sounds trivial to break; have you tried XOR?

Friend: I'll try that now. [Tries ONE value] It's just XORing each character of the password with 0xC9!

Me: Wow, that was fast. Why did you guess 0xC9?

Friend: 0xC9 is 11001001.

Yes, my friend was a huge trekkie. ( http://memory-alpha.wikia.com/wiki/11001001_%28episode%29 )

We spent the rest of high school getting strange looks from teachers that hated that we always seemed to know their passwords, but also wanted our help fixing their computers.
I do the same. The only reason for me keeping Hacker News and Reddit is that I often find more up to date information and more information then say Stack Overflow (e.g. site:reddit.com/r/golang <search terms>). Otherwise, I would unsubscribe and put them in `/etc/hosts` file.

I also don't read the news (who's the president? Kidding...), at least in the typical sense. My colleagues seemed to really be shocked when I told them that, but when I inquired why they could not give me a good reason. I only remember them saying to discuss current events. I figured if it's big enough deal and important enough I would hear about from other sources.

I read Ars Technica, Hacker News, and I am subscribed to a few Subreddits (Games, AnimeDubs, Vita, Nintendo, GameDev and related, but that's it). I have a multireddit for Programming, Startups, and Netflix/Amazon Prime movies/shows for when I need to put the computer down.
On going into the app to let it know when it gets things wrong: I’d love to have it just listen for a “thank you” for a few seconds after it does whatever it thinks we’ve asked it to do.
There is no $6T barrier, the infrastructure already exists. TLDR: This article focuses more on the cost of electric cars (which is valid but not really relevant) with a passing mention on infrastructure.

Bloomberg provides no clear backup on the math (“according to Goldman”) but I’m guessing they are pricing a scenario where all electric cars are completely drained and charging to full all at once. Practical usage is more like a trickle charge every night. A step further, electric utilities are thrilled to get to supply this energy to you, and there will be a cat and mouse game as car charging software works to avoid peak electric surge pricing. Electric utility remains the winner, since they can heavily incentivize time-shifted charging (i.e. dont start charging until 1 am, get half price kws!), and they can run their traditional plants more efficiently or even issue firesale pricing notices for sudden oversupply from renewables.

There is no barrier, there is modest opportunity, and the implication of the barrier is “i’m not buying a car because the national grad can’t support me!” In the same breath, the article discusses how electric autos are selling like hot cakes.

Edit: for BMW, I found this

>Here's the number breakdown: BMW sold 14,450 passenger cars in the U.S. market in August. This number includes sales from compact crossovers like the X1 and X2 as well. That's a 13.5 percent decrease in car sales from August 2017.

That is for August too, so this has probably worsen since then.
Perfectly valid comment, I do not see reason why it is being downvoted. Despite being a democracy, many things the government does in India lack transparency, and the press despite being nominally 'free' are very much complicit in maintaining the status quo.
You’re just redefining monopoly to suit your purposes.
Is it just me or does the story inexplicably blow up the boys tech proficiencies and then almost casually mentions that all they did was log in to school computers with credentials from a post-it on the machine itself in a public space?

How are they at fault if said credentials grants them access to unprotected sensitive records and an obviously badly exposed administration system?
> That’s a lazy comparison.

In both cases, you are operating inside a platform economy. I.e., an economy that's embedded inside the real economy, and it's being regulated by a company (as opposed to the government).

These companies can do anything they want. The premise is "if you don't like what company X does, then find work elsewhere".
The OpenWeb seems to work pretty well, at least from the standpoint of not getting viruses or malware from it. You could argue about tracking users, but it’s not like the native Facebook iOS doesn’t collect lots of data on you.
Ha, I'd print it and put it on the wall too.
Data leaks like this are inevitable. Plan for it, moot the problem with proper design.

The correct answer is to encrypt all demographic data (PII) at rest using translucent database techniques.

Just like a properly salted, encrypted password store.

Because of data interchange, individuals will need globally unique identifiers, eg Real ID.

(These systems still require access & audit logs.)
"It’s not simply the insidious dehumanisation and the patronising that bothers me - which to be fair, is a human condition - rather it’s the attempted commoditisation of what is a highly specialised trade. When you trivialise a trade, you make the trades-people interchangeable."

This pushback has been going on since the very earliest days of the attempts to professionalise software development. Here's Nathan Ensmenger in "The Computer Boys Take Over":

"In response to this perceived challenge to their authority, managers developed a number of interrelated responses intended to restore them to their proper role in the organizational hierarchy.
The first was to define programming as an activity, and by definition programmers as professionals, in such a way as to assign it and them a subordinate role as mere technicians or service staff workers. As the sociologists Haroun Jamous and Bernard Peloille argued in their groundbreaking study of the organizational politics of professional development, this technique of reducing the contributions of competing groups to the merely technical is a time-honored strategy for defending occupational and professional boundaries. We have already seen some of the ways in which the rhetoric of management literature reinforced the notion that computer specialists were self-interested, narrow technicians rather than future-minded, bottom-line-oriented good corporate citizens. “People close to the machine can also lose perspective,” maintained one computer programming “textbook” for managers. “Some of the most enthusiastic have an unfortunate knack of behaving as if the computer were a toy. The term ‘addictive’ comes to mind.”"
If you're using a 5% significance level, you'd expect 5 datasets of 100 to come up with a statistically significant result even though there's no there there (ie even though the null hypothesis is true for all the datasets). That's by definition.

This is even before p-hacking.

Having said that, the study reported on here has significance levels better than 1%:

> The farther away a municipality (in dots) is from a historical mission, the lower its literacy level today. This unconditional relationship is negative and highly significant with a t-statistic of -4.36.

So, notwithstanding the experts here eyeballing the graph and dismissing it as embarrassing, I'd say there is something going on here.

My impression from watching a few Youtube videos of Tesla owners who are not in warranty [0] is that they aren't actually very cheap to run.

In theory, they should be inexpensive - electricity < gas and there are physically fewer parts, but it sounds like there were substantial teething pains. We'll see if/when they got to Toyota levels of reliability.

>How do the particulars of this case have any relevance as to...

Because the facts of this case are direct counter examples to all your points.

You claim no one is surprised Alexa is used in court against homeowners. Surprise Alexa (and video surviellence) are actually being used as a alibi for the homeowners innocence and potentially helping bring the murderer of the homeowners girlfriend and friend to justice.

You bring up warrantless searches. Again in this case no warrant would be needed because the homeowner would want to voluntarily waive their rights and turn over any and all recording that might help prove his innocence and bring the murderer to justice.

It’s strange you would question why I would bring up the facts of the case and call that a think about the children arguement. Whereas ignoring the facts to make arguements that are contradicted by the facts of this case is exactly that...a think about the children [privacy] arguement.

That does not demonstrate anything. It could "buffer" the data it wants to send and only send it after the trigger word is detected, precisely to trick such naive analysis.

Sorry, but this is completely ridiculous. You can slice and dice any market down enough to where one company is a “monopoly”.

They’re the only taco store on this block! I demand the government force them to lower their prices so I don’t have to walk more than 50 feet!

If you don’t like it, switch to Android. But of course, the real problem is that people don’t want to switch to Android. They want to have their cake and eat it to, but that’s unfair and illogical, so they start slicing down the market to where they can cry monopoly and ask the government to force the business to give them what they want.
No because in a distributed system, you can't rely on SQL transactions. i.e. if you need to make one API request to start the transaction and a second API request to commit it/rollback - you can't hold the SQL transaction open between those.
The Algorithmic Bonus Mindset
Agreed that HN and Reddit are basically just replacements for Facebook. Former becoming more and more like the latter.

I disagree it’s “information”. The article is usually wrapped in opinion, and you’re in the opinion section now.

Maybe the appeal is that when the opinion is from some you know (a “friend”) you feel obligated to acknowledge it and on an anonymous forum you can more easily ignore it?

Reddit vs Facebook I think is just social media preference.

IDK... I’ve found myself skipping articles and jumping right to the opinion section in order to “save time”. Bad habit, but I just don’t have time to read everything.
Ok, thanks. I was under the impression that CCTV systems are always "closed systems", in the sense that one can watch the recorded video only after an incident (where an authority has to provide the password).
The assumption you used helps to answer your question.

"at a profitable rate"

So this assumes that the chicken-and-egg electric car/infrastructure can evolve together profitably while reaching critical mass. (To be sure, I believe they can, but it will take either government or brave investors to get there.) So the question really is "can $6T be divided up into the cost of whoever is paying for it, i.e. electricity users to maintain profitability as it is built?"

If you assume the answer is yes, there is no question!

(As for the "maintaining the grid", yes, obviously we are already maintaining it profitably. No need to build critical mass/adoption or initial infrastructure investment, so no interesting stories to write!)
It's called multiple testing. You're not guaranteed to get a misleading result, but it would be expected. The definition of the 5% significance level used in p-value testing is that given 100 junk datasets (distributed similarly), you would only expect 5 to show as strong an effect.

However, I don't really see what this study has to do with multiple testing. As far as I can tell, they had one dataset, and they tested that, and they got a significant result. Nothing fishy there. Sure the data is noisy, but wouldn't you expect that given how coarse the data is, and how many confounding factors there must be?

Containers were always a crap. Everyone is bragging about speed and security. That's all bullshit, it's like jails for BSD. There are tons of exploits, same goes to speed. There is NOTHING comprared to bare metal, have you ever did any benchmark on applications cause my team did and find disturbing results enough to write an article and be king for one day. Docker is made for rock star developers, not rational system engineers.
Yeah it's a fair point. The case I mentioned is for Cuvva, which currently is mobile-only.

Webmail is always a decent backup option though, so doesn't give me too much concern in terms of people getting stuck. But may be a little less seamless, particularly if they're using a shared/public computer. That scenario throws password managers out of the window too though.
Is it a concern that you don’t consider social media usage as “interacting with people”?

If you were browsing wikipedia I’d understand. But your in the comment section talking to me, believe it or not, a real person.
> About memory, despite being shared memory, does a container in lambda running a node process use 35mb of RAM? Because that's the claim.

What do you mean by "use" in this context? Does every program that links to glibc "use" the memory for glibc? (The answer is no, because the page cache is shared. But if you just looked at memory usage you might be fooled into thinking it is copied for every program.)

Containers use a drastically tiny amount of in-kernel memory. We are talking fewer than a couple of kilobytes in the worst case.

It appears to me that the main worry was with using Kubernetes, and they've applied this to containers as a whole. I agree that in this sort of usecase Kubernetes really doesn't make sense (using container images at all makes no sense in this case), but the core kernel primitives and simple container runtimes available are more than suitable.

There is an argument that having no userland-kernel context switches has a performance improvement (and it does) but I would like to see data before accepting at face value that "context switches are expensive" is an appropriate thing to optimise for.

After all they are still doing context switches, it's just in userspace. And if v8 is multi-threaded they've just reinvented the N-to-M scheduling model that is very well known to be fundamentally broken because of various well known pathologies.

Yea? Have a pro-gun discussion on HackerNews and tell me how it’s so much better than Reddit.

HN has its own problems. For one, there is a growing discontent for different opinions (downvote happy), and two, there is one “channel”, so it’s mob rule for opinion.
I think the point is, if all they sent was a wiki article, they wouldn't be responding to the spirit of the subpoena. Instead they'd be expected to write up an explanation that they don't keep full data, and they would probably still be required to hand over metadata that might be useful.

I would hope the researchers were competent enough to space out their explicit uploads with varying periods of noise, while also finding a decent approximation of how much data is uploaded per x seconds of audio.

Sure, Amazon could use all sorts of tricks to attempt to throw off reverse engineering, but it would be pretty hard to do so with a large enough set of tests.
Right, but that's because they don't actually run Docker. They have a much better designed manager process that creates LX-branded zones.

My point was that "Linux containers" (so tools like LXC, or runc, or others) are more than capable of being used in this way. Docker has a variety of architectural and other problems that result in it not being as friendly to this kind of use case.

So when you run "docker containers" on Joyent they just untar the image and run it in an LX-branded zone. There is no Go or other problems and they sure as hell don't run Docker as root in their control plane.
Have you looked at the statistics? Do you think you can glance at a graph and have better insight than someone that has carefully studied the underlying data, including run a regression over it? Do you realise that the trend line slope has a t-stat of 4.36? Did you notice that all lines contained within the 95% confidence interval for the trend are negatively sloped?
Yes sometimes legitimate concerns about the effects of immigration can sometimes be miscast as xenophobia.

However, there can be no denying that Japan taken in aggregate, is xenophobic. They have made it difficult to emmigrate for even skilled workers, and even native born descendants of Asian immigrants from Korea, China, Taiwan, etc sometimes experience discrimination in Japan.

There is a defensiveness and sometimes hostility about cultural differences with foreigners and descendants of immigrants in Japan. It's not as bad with the younger generations but it's still there and has been the basis from which their immigration policy has arisen.
