I am in no position to question EM. But I was hoping he would give some good explanation for spending resources on SolarCity acquisition but nothing. Nothing in this master plan explains why SolarCity was bought other than some hand wavy explanation about inherent difficulties of two separate companies working together. It still doesn't seem like a good purchase for Tesla specially at the moment. Solar car and SolarCity seem to only have the word solar in common :) TBH I am still fuzzy how expensive purchase of SolarCity can benefit a solar car manufacturing even in long run.

Why abstract? Its pretty concrete, so more like TeslaFactoryFactoryImpl.
Over correction does already happen (not sure if you meant you haven't yet observed over correction, or the negative fallout of it). See for example Glowforge's approach: https://glowforge.com/blog/at-glowforge-we-pay-for-diversity...

While I absolutely wish that any person felt welcome in tech regardless of race, gender or other choices like orientation, I'm not convinced this is a good approach. It's an explicit statement that they are desperate for diversity, and as a result it calls in to question the justification for those hires. How much did the candidates diversity factor in vs. their competence?

They claim that non-minorities won't be disadvantaged by them and I believe they are being honest here, but it still sends a very mixed message.
Good feedback, in general we thought there are enough articles out there about the various operators that you can use with JSONB such as https://hasura.io/blog/the-unofficial-guide-to-jsonb-operato.... We may take another pass through though to see if we can add some more complex examples to highlight whats possible.
Should humans be monitored and have driving privileges revoked if they drive erratically?

Historically yes, if you cause problems your licence is revoked and in some cases your vehicle is seized.

I look forward to the rise of the machines, with humans losing driving privileges for simple things like wandering across lanes without signalling, running red lights, hitting pedestrians or bumping other vehicles in the parking lot.
Vanilla CSS is verbose, not DRY, and challenging to navigate and maintain.

You don't NEED a preprocessor. But as you find yourself writing larger CSS codebases or trying to do more sophisticated things with it, you may find yourself wishing for the features you get from a preprocessor.

Those are streaming websites, correct? I downlowd my music instead of using spotfy so I can listen to it where and when I want, the same with movies. HBO Go I would pay for though as I rather watch their shows as soon as they come out than download it later. But it's not available in my country.

Some quick napkin math: 3 million miles a day gets you 6 billion miles in 5 and a half years (not counting the ~100mm miles they already have). Since the daily mileage rate will only be growing exponentially, it's not unreasonable to assume that Tesla hit this number in under 3 years.

Not sure how they came up with 6 billion as the magic number, but if that's accurate, that's very soon. It also helps that there are no real government stakeholders in preventing the proliferation of self-driving cars. People just need to generally believe that they are much safer than human drivers, which of course is not true yet.
Note the Tesla focus on solar, since wind power doesn't work so well on Mars :)
I'm technical, and I do get daily use of many many websites, but there's still the odd one that stumps me.

I blame that on the terrible UI of some websites. Especially government ones for some reason.
"A first principles physics analysis of automotive production suggests that somewhere between a 5 to 10 fold improvement is achievable by version 3 on a roughly 2 year iteration cycle. The first Model 3 factory machine should be thought of as version 0.5, with version 1.0 probably in 2018."

What that really means: Tesla is going to lose a ton of money per car on the Model 3, or raise the price, until at least 2022. That's realistic. His two top production guys quit when he announced 2018 as the delivery date for the Model 3. His new production head, from Audi, may have given Musk a reality check.

Tesla produced about 50,000 cars in 2015 with 13,000 employees, about 4 cars per employee. Ford produced 3.2 million cars in 2015 with 187,000 employees, about 17 cars per employee. Toyota produced about 9 million cars with 344,000 employees, about 26 cars per employee. So Tesla needs to get their productivity per employee up by 4x - 7x to play with the big guys. Clearly Musk has done the same calculation.

Now, though, he's admitting that they can't do it by 2018. This is prepping the stockholders for bad financial news. Tesla is going to burn a lot of cash through at least 2022.

There's no reason that Tesla can't get their productivity up to at least Ford levels in time. Ford has a much broader product line, and Tesla's car isn't that complicated mechanically. But it's not instant.

Technically better doesn't inherently mean more enjoyable, though.

I would say the success of "VHS Camera" apps and the like (and mostly with people scarcely old enough to remember what a VHS looked like) suggests there's quite a bit of taste for the general aesthetic of analog video.
Depending on your requirements micro-services may be a good or a bad solution. If the communication/protocol becomes too chatty that may be a sign you are doing it wrong.
I suspect Tesla will move into aircraft and oceancraft in the long-run, if you're interested in "other industries." He's mentioned the electric jet enough times. And why would he create a new company for it when he's got all the expertise and business structure at his fingertips already?

Solar harvesting in space sounds really cool, but how do you get that power back to earth? Even if there were a way, it's not necessary or effective. He's said very clearly that you could just have a giant square of solar panels in the desert and it would power the whole country. Why bother putting them in space? No advantage.

However, SolarCity IS likely to provide the panels for SpaceX's satellites, of course. So there is that form of solar harvesting in space.

I'm implying that you're long-winded and it weakens your argument. If I reduced your response, I'd reduce it to, "You hurt my feelings and I'm angry about that." Fair enough, but the rest is so much filler.

You're confusing streaming (renting) with purchasing.

On iTunes, EVERYTHING is DRM free. If you purchase it, you get a mp4 (or mov), and that's it. No DRM.

So nothing is stopping you from paying for much of this content legally.
That's a great point. I'd imagine they need 3-4 times the power of a car but have 100 times the surface area. It seems like that could actually work.
Humans would probably be more erratic if the vehicles drew attention to the fact that they were self-driving.
Yes. Simply entering a username into a Microsoft login page will, depending on the domain you landed on, redirect you before you enter a password.

How to enjoy 3D movies by converting normal video to 3D video
You make a good point about health checks. Its easy to conflate single node health with overall service health. The LB check should really be about "can this node serve HTTP traffic", even if the non-health check requests can only send back 5xx responses because their dependencies are failing.

I've also had the opposite problem where the health check would answer 200 OK, but the real app itself had a corrupted internal state because of a poor design/threading bug. If the health check had been the home page the node would have been pulled from the LB. While a more in-depth health check would have helped here, I think its better to alert/monitor/kill any node with a higher than normal error rate and leave the health check simple.
Same! SCART [1] was amazing; it was a single plug for analog video and audio.

You'd typically have a coax splitter so both the VCR and the TV could get an independent feed from cable/antenna. Then you'd use SCART to get the VCR's output on the TV's 'AV' input, a special input mode like 'HDMI' on modern TVs.

Is there a legal lesson to take from this when it comes to using cloud services hosted in the US where you can be affected by US laws just because you hosted a site with links to PDFs from Elsevier in an S3 bucket which itself happens to be pointing to a US datacenter? I haven't read it all, but there must be more to it than having used a US hoster that made the guy an easy litigation target.

> I've witnessed people assert that ECC is a scam, waste of money and similar. Even after I point them to that link I posted above, they still seem to believe that It Won't Happen To Them. ("I don't have millions of machines.")

If by your own citation 92% of DIMMs operate with zero errors per year, and a consumer machine has at most four DIMMs, then it is actually pretty likely that any given consumer machine will operate without RAM errors even without ECC. And when you multiply by the low probability that a DRAM error will cause catastrophic data loss, then it is very easy to come to a reasonable conclusion that ECC is not worth the expense.
Do you think they'll have solar panels on the trailer? Would they have to roll them on/off when they switch trailers?
The point when you transition from "X and Y are different" to "X is better than Y".

It commonly takes the even more pernicious form of going from "X and Y are different on average" to "any given X is better than any given Y". If you're lucky, this last statement at least has a "until proved otherwise" caveat.

Unfortunately, history is rife with this sort of reasoning. People slip into it _really_ easily. It doesn't help that there is a natural tendency to perceive your in-group as better than out-groups, so to the extent that X above ends up feeling like someone's in-group and Y ends up feeling like an out-group, the "X is better than Y" conclusion is very hard to avoid.

We are working on pre-processing text corpus to generate assumptions and presuppositions using NLG.

Our initial aim is to index the whole Wikipedia and have pre-generated NLG for all pages as additional info for better searches.

Right now we are using Lucene & Syntaxnet but I haven't found a good library for hierarchical clustering of text

Not necessarily. A lot of people have wisened up to Musk's invasive and destructive management style. Don't think the frequent departures from the company at all levels of hierarchy have gone unnoticed.
Ask HN: Is callback hell exaggerated?
I played around with just using callbacks as a test and it wasn't bad at all.

I can barely find anything on the internet about callback hell before 2010 to indicated that it was a real problem at all with javascript.
I'm actually curious about the bus, too. Sounds weird. But I trust his judgement, I'm sure it'll be great. He has a track record, you know.

Regarding missed promises, if you're saying that as if to suggest that what he's promised isn't nonetheless coming true at a pace faster than anyone else could have possibly delivered, I think you're wearing blinders.

Cities already tend to have limited parking. We might see more parking structures located in cheap out-of-the-way locations rather than near places people want to go. And street parking could go away in favor of consolidated parking structures, freeing up road space for both car traffic (with extra lanes) and foot traffic (widen sidewalks).

But I think it'll have an even larger effect on suburban areas. Shopping centers, strip malls, and similar will no longer need to have massive flat single-story parking lots, freeing up a huge amount of space. Likewise for major employers, and commuter parking lots for mass transit.
> If you're an American, you're twice as likely to die with a steering wheel in your hands as you are to die at the hands of a murderer. Human-driven vehicle deaths cause grave second-order suffering for families and friends - and hurt the economy.

If you're an American you're more likely to die from suicide than you are from motor vehicle related injuries. You're more likely to be poisoned than to die in a motor vehicle crash. You're 16 times more likely to die from heart disease or cancer.

Compared to 1950, motor vehicle death rates have more than halved.
Because the people who run those companies are literally extremely old, very ignorant about technology, and they do not care what people want, only what they perceive as the best money-making investment.

They don't want change, they want business as usual, but their business model is dead, it's dead and rotting and they are going to accept that one of these days. Meanwhile pirates will keep stealing their worthless products.

There's a very interesting video from Keith's Code's superbike school where they built a motorcycle with an extra handle bar that's fixed to the bike to prove that leaning doesn't actually turn the bike much at all.

https://www.youtube.com/watch?v=HOGQ-HePrT8

I know this works for sure on a motorcycle, and I've tried this experiment on a bicycle too, you can turn a bike right just by pushing the handlebar forward with your right hand. Totally counter intuitive but it works and I'm pretty sure we do it subconsciously when we lean by pushing on the handlebar and we end up counter-steering.
For me the stream of consciousness style didn't work at all. But I'm referring specifically to these passages of the article, which set the novel in a new context for me. I always appreciate hearing someone else's well-articulated reasons for why they adore something that I did not, particularly when the sheer joy of their experience shines through.

>Joyce picked June 16 as the time of the novel partly to commemorate his first date with his future wife (more on that in a moment), but also because it was an otherwise ordinary day, on which ordinary people did ordinary things. Like the rest of literary and artistic modernity, the novel pits the epic against the mundane, and Joyce’s version toes the line with virtuosity.

and

>Ulysses bathes in low-culture vulgarity, even if it’s hard for today’s reader to see it clearly. The choice of June 16 as an homage to his future wife’s first date is partly romantic, but partly bawdy, too.

>Instead of standing on the shoulders of giants in faux-humble deference to tradition, as Ezra Pound and T. S. Eliot had done by incorporating classical references and source material, Joyce devoured and disgorged them again. And it was beautiful and real, like watching a drunk heave outside a pub in the wee hours of the morning. This is life.
Also (for a bit more history), I had already implemented the V8 / Java integration. I did this because we needed a performant JavaScript engine on Android, and Rhino just didn't cut it. Adding the Node integration was (theoretically) pretty easy, although because of how Node.js is linked on Windows, it gave me some headaches.

Part of why I did the Node / Java integration was to see if there are any use cases. We'll see, I hope someone finds it useful, and if not, I learned a tone.
You are comparing premium tesla sedans with ford and Honda cars, of course premium car will take longer to build. Porsche for example produced 189,000 cars [1] in 2014 with 19,000 employees. And the average price of Porsche car is also lower than Tesla's.

I'd point out that ReachNow actually started life as DriveNow here in San Francisco. They left town once they made the poor decision to move from having "stations" to on street parking only.

Author here, thanks for posting this cool to see it on Hacker News (was wondering where all the hits were coming from!).

If anyone has any questions about these tools, or feedback on their experiences using them especially with other SDRs than I have tested with, I'd love to hear it. I have only tested with the SDRs in the article I have access to, but in theory it ought to be possible to support others, including the up-and-coming LimeSDR recently featured on Hacker News: https://news.ycombinator.com/item?id=11610521

And any bugs reports and/or pull requests are of course also welcome. Cheers, -rxseger
"simple things like ... hitting pedestrians"

That doesn't seem very simple to me.
Are you advocating for more dispersion of companies around the country, or a different tech hub?

I'm not sure the former is good for me as an engineer. It'd be nice to afford a decent house, but less so if I have to sell it and move cross country to advance my career or flee an employer going the way of Yahoo. Barriers like geography, moving costs, social ties in different cities keeping the best employer-employee pairs from finding each other are a form of inefficiency that I'm not sure we should seek to introduce.

I'd like the latter - we could build it somewhere more development-friendly, which would make it less insane than the Bay Area housing market, but putting a huge industry of well-paid professionals somewhere isn't compatible with low cost of living (see: Manhattan, DC).
I still have a VCR that I very occasionally use to watch some old VHS tapes. Nostalgia nite, with buttered popcorn. The OP article will probably be the kick in the butt I need to send those tapes off for copying to DVD.

When my VCR finally dies, I'll probably miss most the flashing green "12:00". It indicates that in 31 years, I never did RTFM to figure out how to set the time. And never will. One finds one's inner rebel in the least significant places....

I haven't figured it out, but my intuition is that the increased energy requirements of a tractor trailer mean that there isn't enough area there either.

Back of napkin, it looks like you get ~3*15 meters of roof which seems to translate to 10 kW of output under good conditions and then you need something like 150 kW to rumble up the highway.

I'm not sure I agree. I suspect the real issue is the government supplied debt financing. I think government subsidies drive up housing prices to the extent that you NEED to take out a loan to pay for a house rather than being able to pay for housing up front out of savings.

Housing prices would be a lot lower(and more affordable) were it not for all the money unnecessarily doused on it.

Because prices are so high buyers must participate in credit markets which is like socio-economic ankle weights for poor people. They either get screwed or excluded(and screwed).

EDIT: The Higher Prices also ensure that people need continue to work to "pay off" their mortgages. If housing prices weren't artificially high they'd already be "payed off" having been payed for with savings. cf: https://news.ycombinator.com/item?id=12131855
