South Carolinian - we don't, insofar as I'm aware, have the PBA card but it's a common enough thing to see folks with the local equivalent, a sticker, given for donating to the local PBA group on the lower-left hand corner of the rear windshield, such that an officer would see it when walking up to the window.

Now I have no idea of it's efficacy, but I've bumped into a few folks who swear by it. Like the card it would be good for, at best, a warning on a speeding ticket or another basic moving violating. Of course I've gotten the same treatment by simply being respectful to the ticketing officer, so who knows? As gfodor mentioned[0], there are likely certain dynamics to the situation and I can imagine an officer seeing that as too on-the-chin.

Finding Netflix fairly frustrating these days. Despite their runaway success they haven’t really done anything to change the Hollywood model. 99.9% crap with a sprinkle of watchable content. And despite the hoards of engineers and machine learning wizards they employ, discovery and interface has regressed in their product. Only reason I haven’t canceled yet is avoiding the hassle of going full torrent/YouTube.
Yeah it's weird to me that this article didn't talk about China's dumping of solar panels. Bloomberg has other recent articles talking about it https://www.bloomberg.com/news/articles/2018-01-21/trump-chi...

Reeks of "Trump is for it so it's must be bad" issue that has plagued journalism since he took office.

There's pros and cons to this method of fighting dumping but it's certainly a good thing for American solar panel manufacturers just not the installers (in the short term at least).
There is one problem that the blockchain solves.

It can make a large hostile network with extremely high computation resources act like a single computer with the performance of a 10 year old desktop.

There is a wide diversity of cities in the US. You can go to places like NYC, Boston, Seattle, San Francisco, etc. and see examples of cities with decently dense cores and functional public transit. But then you can go to cities in the South, for example, where it's almost impossible to get around without a car.
You can schedule Ubers ahead of time.

If anyone has any info, I would love to know how often YC reject companies/ideas because of a conflict of interest or if there's any rules/guidelines around that?
Oh, but you think that's enough to found policy recommendations on? If it's just an inkling with no data to back it up, maybe keep it to yourself?
Sense8, The Get Down, Marco Polo. They are planning on spending 8 billion on content this year. Lets say they spend 10 million on a couple puzzle/king/angry bird style games. That's .125% of their content creation budget.

For anyone reading this, I highly recommend doing as much as possible within MATLAB. Its secret sauce is that it operates on vectors (arrays and matrices) instead of primitives (ints, floats etc). It simply runs circles around almost every other language that I've used. Its real power comes from its domain toolboxes (libraries):

https://www.mathworks.com/products.html

But the language itself is uniquely readable even for its brevity. You can do things in a few lines of code that would take 10 pages in a scripting language or 100 pages in lower level languages like C or Java. Here's the most concise explanation for how JPEG/MPEG compression works that I've ever found:

If you can't afford MATLAB right now then you can at least play around with the language in GNU Octave:

I can understand why people are hesitant with Wayland, because they look at things like systemd (which is still a usability nightmare, although it does make packaging much easier).

I recently ran Wayland/Weston on my home theater PC running Void Linux. For the most part it semi-worked. I have few native wayland apps, so almost everything ran through xwayland. Steam was weird; as the mouse was offset about 300px to the right and down. I'd have to hover away from stuff to click on it. Kodi would often Flicker (my HTPC just uses Intel ingratiated graphics). Most of the Games (both Steam and Humble) worked fine though.

Weston, the reference implementation, just isn't that great. I ended up going back to X11/Gnome3 after getting sick of the graphics glitches and bugs, and forgot how terrible gnome is now (I've used i3 on my desktop for years).

I might go the Wayland route with Sway (i3 clone for Wayland) on my dev box, but Weston was honestly still too buggy for prime time on my media pc. I do agree though, X11 is old and awful and Wayland is a big improvement over X11. But I do run X11 apps remotely over SSH (something the wayland people assume no one does) and when asked about it, they kind just hand wave everything away like someone just needs to write a plug-in and it will work.

postmarketOS might be the big push to really get Wayland mainstream. I'm really impressed by postmarketOS and hope it will be what Linux was for the x86/PC in the mobile world. You could install Linux on everything back in the 90s/2000s. ARM is a cluster fuck of random shit connected to random pins that are different on every SoC. This is a real major step to true alternative mobile OSes.
They most likely would not want you to leave the company on that salary to value creation ratio.

Can you create 3M value on 100k salary at any company or just this one though?

If you can demonstrate that return others would be willing to pay more for your services.
Agreed, also just want to say thanks, this is awesome news. Much appreciated!

> Chinese perspective it's the perfect ultra long game... the rest of the world is in for a massive shock

For centuries this has just been called plain capitalism. Now that China is doing the same, Europeans and Americans are in a shock? How interesting.
For most devices, we're running the vendor forks of the Linux kernel (mostly Android). The source of all of them is available, just like the mainline Linux kernel.

With that being said, the stock Linux kernel and its vendor forks contain obfuscated code and even (small) blobs. To get rid of that we would need to package something like the Linux-libre patchset [0]. From what I know, no one is planning this currently, but if someone is interested in this, I don't think anyone in the community would be against having this as option.

Same is true of gold, diamonds, ivory, other items whose rarity makes them precious.
Yes, I lived in NJ around 15 years ago, and PBA cards were well known (but not much talked about), and that's precisely the way they worked. Subtly flash the card to a cop, and they might ignore it, they might take the card and skip the speeding ticket, or they might just skip the speeding ticket.

Yes, corruption, but not exactly a get out of jail free card either. Or that's how it seemed to be, mostly, in NJ, over a decade ago. :)

It's very possible that things are worse today (such things tend to devolve over time), or worse in NYC, or worse than what I saw at the time.
Three (decimal) orders of magnitude difference, I think. (15,586 firearm deaths in the US in 2017.)
It is amazing to me that they offered a superior interface by any measure back in the DVD days. The AppleTV interface for Netflix is a disgrace. I don’t understand how they have all of these brilliant engineers, yet make an interface worse than what Spectrum provides.
China has much better chances of fully automating their solar cell manufacturing, because they are selling worldwide and so have much higher volumes. Presumably the dramatic declines in cost we've seen over the last few years are in large part due to this phenomenon. The US solar-cell manufacturers will remain in the same kind of high-cost, low-quality ghetto that Argentine air-conditioner manufacturers are in.

Trump can definitely cause the inevitable to leave the US playing catch-up in the 2030s, unless he's out of office soon.
I hadn't considered that outcome, but it's certainly possible. However, state governments are large customers to most vendors, so I would think some ISP would step up and get the business.
> A common bias amongst Westerners who have never visited China

I meant this sentence in direct reference to what happened with solar panel productions (because scaling and dumping in an extremely short timeframe was what happened and broke the neck of European solar).

I know that China has a massive ecosystem of invention (evidenced e.g. by the "gongkai" reports by Andrew Huang), I didn't want to laugh that down - sorry if it came across that way.
I do wonder, to UK police have a similar system to Norwegian police (that are in general also not armed) where there are handguns locked in the patrol car? They still have to radio in to get approval from the commanding officer before arming themselves though.

BTW, in recent years there have been a "temporary" general arming of the Norwegian police that have lead to a bunch of incidents (most of them accidental discharges as the issues handgun do not have the typical safety, as they were not intended to be carried on the hip for extended periods) including one where a officer fired a warning shot into the air...
Ask HN: Why do gravity waves travel at the speed of light?
ELI5 (OK, ELI20, but not a general relativist).

The speed of light is the speed of propagation of electromagnetic radiation. It is fixed by two constants: the vacuum (electrical) permittivity, and the vacuum (magnetic) permeability.

Why should the speed of propagation of gravity waves have anything to do with either of those? They aren't electromagnetic at all.

Or does something more fundamental force both electromagnetic and gravity waves to travel at c, and that more fundamental something thereby imposes a relationship between the vacuum permittivity and the vacuum permeability? If so, how?
This is a really good article, I'm impressed. If you read only one deep learning article this month, make it this one.

I'm going to borrow that analogy of "teenagers perceptions of sex" - it's hilariously accurate for deep learning.
In many ex-soviet bloc countries (e.g. the Baltics) and other countries with sort of 2nd-world level of development (Greece), railroads are terrible (either due to lack of infrastructure of inability of the government to maintain it) but bus service is excellent (easy to rapidly improve road quality with a new government, easy for private companies to spin up bus service).
> For this requirement to have any meaning, Montana would need to be able to enforce it (ie choose another isp).

Why? Can't they also just fine them in increasing amounts until they comply?
It's been suggested. The problem is that having to run only during the day, and perhaps only in certain seasons, is a huge impediment to most of the applications you could think of because most energy intensive processes tend to be capital intensive as well.

For instance, I did some cursory analysis on building a chemical plant to do ammonia production in order to take advantage of the negative energy costs that were available in some parts of CA for hours a day thanks to a combination of the duck curve and the overcapacity at Oroville. When you're only running things 2-8 hours a day, you are amortizing the fixed costs over a much smaller output than something running constantly. Even getting paid several cents per kwh to take energy off the grid, it seemed hard to turn a profit.
My inkling is that this is not a policy paper but a forum. I may be wrong!
Is that an Equalizer in your pocket? (2010)
in the video referenced by @aberoham , a the end there is a question to the presenter (Josh Berkus), about the 2 types of replication their deployment tool is supporting.

this was on about 33rd minute of the presentation

He suggested , that if you need to use , synchronous replication, to use PostgreSQL 10 with synchronous quorum replication, so that it will not block transactions if one of the replicas fail.
Let me be clear that I'm not advocating for getting rid of the grid. Like you said, on days when local generation doesn't meet demand, the grid will be very useful. What I'm saying is that local generation would supplement the grid; perhaps make it so that it can handle the additional loads put on it by millions of Electric Vehicles.
The two options you mention are the ones I see used most often (with React & Vue being 3rd/4th), but I wouldn't say any of those are "frontend equivalents".
That depends how many people you need to move and how often you need to move them.

Rail has a high capital cost, but lower operating cost due to the fact that a single engineer (and maybe a conductor) can run a 2000 passenger train while a bus driver carries 50 - 100 people so you only need about 1/20th the number of operators.

Another drawback of buses on the road is that unless they have dedicated lanes, they are stuck in the same traffic as cars.

BRT kind of blurs the gap between the two.
It's a conscious decision, but that decision may be greatly influenced by the content being prohibitively expensive for them to otherwise obtain.
If they had bought BTC with the seed round (600k total, not sure how much of that round YC did though) it would be worth $560M. It has gone up roughly 1000x since then.
The depth output of our vision stack is currently not accurate enough to reliably measure relative speed. However our ML team is currently working on new models. Maybe in the future this will be accurate enough to do this without a radar.
That’s just crazy to me. The amount of effort you have to put in to achieve this with Kubernetes is way beyond what you would have to do to write you application in Elixir. If you already have multiple services in another language, it may be worth the effort, but the BEAM gives you nearly for free what is relatively expensive to get elsewhere.
And there are taxi companies as well. The point is that there is minimal service. You can't just pick up a phone and have a car there is 15 minutes.
Or ScalaJS w/ ScalaTags?
So you compare average speed (that includes all stops) with max speed of a car...?
I don't think "how fast a car is capable of going" is the relevant comparison in speed of transport via rail vs. bus.
The nasal vaccine has been deprecated for a long time now, I'm not sure you can get it anywhere ATM.

Generally, is there a rough percentage of their cohorts that are pre-revenue? Or does it vary wildly each round?
If they did that, they wouldn't become cops in the first place.
It’s a private company. That’s among the many reasons that trading in private companies is different than trading in public companies.
Elixir is great for stateless apps. So are a bunch of other platforms.

Elixir is exceptional at stateful apps. And it is true, many of those things are now handled through K8S. However, K8S doesn't handle everything and requires a lot more ceremony and infrastructure than what you can get within the Elixir/Erlang ecosystem.

I think there might be a way to work with Elixir + K8S in a way specific to the domain you are working with. Not everyone needs to be able to hot-reload code without dropping live connections, but if if you do, and you want to deploy on K8S, then you can try writing a K8S operator that encapsulates that idea. However: https://gravitational.com/blog/running-postgresql-on-kuberne... (which is more about how every distributed system requires deep domain knowledge, not just specifically about PostgreSQL)

I have not deployed Elixir on GCP. I have deployed other things though, and I can tell you the private networking is much better set up than AWS. As far as distributing nodes, you can do that with any of the cloud providers.
They have almost certainly been diluted. They don't do their pro-rata generally on each funding round and my bet is that the YC Continuity Fund was only allowed to do their pro-rata. When the Dropbox S-1 drops we will see what kind of ownership they end up with over time.
These are excellent points, but I reckon boring tunnels, dedicated lanes and self driving can mitigate the disadvantages you mention.
If you looking into OTP, you'll see there's quite a but more and to some extent it does things differently than K8 (e.g., Observer, fault tolerance, concurrency and vertical/horizontal scaling w/message passing, etc.). See: https://www.manning.com/books/the-little-elixir-and-otp-guid...
Acknowledged. Thanks for the clarification.
Knew immediately that leverage and margin calls would be involved.
You're kidding on the "Applied neural networks" bit right? A good subset of the features you see on Facebook and Google have neural networks contributing to their functionality.
To what degree does income inequality, consumer debt, and rapidly rising barriers of entry to high-income fields contribute slowing GDP growth? Is there research and evidence on the subject?

I'm just an engineer with basic financial survival skills... but blind intuition suggests fixing those problems is necessary for a sustainable growing economy.

"Trickle-down" theory and growing inequality drains economic activity since the "1%" invest their money instead of spending it. They profit when the public consumes, unless short-sighted over-exploitation by some industries strangle general consumer activity...

It sure looks like we're being strangled. Off the top of my head: urban rent, health care, high consumer debt and student debt reduce disposable income while automation, exporting jobs, poor retraining for adult laborers, and lower small-business access to capital due to banking mergers lower actual income. When businesses close, some of their ex-employees will switch to high-skill high-demand jobs... but most will increase the labor supply in less skilled industries because they urgently need money - putting downward pressure on wages and working conditions.

If I'm wrong, I'd love to learn why, and what other systemic conditions explain our economic stagnation.
No sub-saharan African country except South Africa has really stood on its own feet and been long term successful by modern standards. It's hard to say they would have done any better without colonialism or in the future without Chinese infrastructure. These might all be good things, despite the dependence they create.
Unlike Gold, bitcoin's rarity is artificial, comparison of Bitcoin to high-end artworks might be a more proper one.
I've always found anti dumping actions slightly hypocritical. If they just came out and said explicitly it's protectionist and stopped belabouring other economies with the free trade stick, I'd maybe feel better about it.

Roll on peskovite (that's kind of a joke in context)
> The third party company would take a management fee, purchase insurance to protect against theft of the assets, and be a registered US corporation so legal action could be taken if they committed fraud.

Doesn't that basically mean your ICO is subject to US law, essentially eliminating the main benefit of a "trustless transaction"?
I'm not a behavioral psychologist so I don't think I can offer a professional opinion about this. My point was only that if parents are proficient in another language, they shouldn't hesitate in teaching/talking to their children in it. Seems like a wasted opportunity.

Depends on the traffic and the train -- during rush hour, a Caltrain express train from San Francisco to San Jose is almost always faster than driving. It can take 90 - 120 minutes to drive during commute hours (at 4:30pm, Google says 90 minutes), versus 65 minutes by train.

Having a fully automated solar cell fab locally would be wonderful. We'd reduce the need for big ships burning sulphur-rich heavy bunker fuel oil. We'd be more resistant to China cutting us off without warning, as they did for rare-earth metals. Even a lights-out factory sometimes needs workers, so that is at least a few jobs.

If you want a coal-related motive, try the obvious: Pennsylvania is an important swing state. Mines are hiring again, for both miners and engineers.
Rail is faster and more comfortable than buses in my experience. The comfort is more than just less bumps in the road and less starting and stopping. Some trains even have bathrooms. The bathrooms on the (US) MARC commuter trains I've taken are considerably better than those on flights or Amtrak, for example. Buses usually have no such amenities, and when they do I'm told the bathrooms generally are disgusting.
Well, yeah. The MTA in particular apparently has a 55mph max speed (same link). A car can compete. Keep in mind I'm not counting traffic, but obviously is (currently) a huge advantage for a train. I'm talking more about greenfield projects.
Agreed. I worked for a YC company who's founders went through YC before they even had a company. In fact, they still hadn't landed on one by the time they came out. But they were Stanford and MIT grads, and insanely well-connected.
A question: what are the pluses/minuses of deploying to App Engine vs Compute Engine. Specifically, what are the tradeoffs of Elixir on App Engine? Thanks in advance.
China has one big advantage vs the US when it comes to future innovation potential in biotech: a large cohort of talented young professionals being trained in drug discovery and development

Big pharma organizations in the US and Europe have been cutting r&d workforces for years, and most small biotech startups that are filling the innovation gap hire execs with 20+ years of experience to design and manage the research and outsourcing the actual work to china. Wuxi, a large contract research org in china, employs like 1-2,000 discovery chemists. I think Pfizer employs maybe 100
