* Drones have interfered with firefighting activities in California before

That's what you would think from reading the headlines. "Hobbyists Imperil California Firefighters", "Firefighter-interrupting Drone Pilots...", "Drones Are Getting In The Way of Firefighters", "Drones impede air battle against Californian wildfires", etc. Here's a description of what actually happened:

> On the evening of June 24, he recalls, they noticed a drone. The aerial attack was immediately called off, out of fear of a midair collision; the three air tankers attacking the Lake Fire were parked the rest of the day. And the fire grew as a result.

A helicopter pilot saw a drone and grounded the helicopters.

The papers took a judgment call and twisted it into a story of active interference between drone and helicopter. And even that makes the generous assumption that this was an honest judgment call and not an intentional (and highly successful) attempt to grandstand.

While most reasonable people would agree that drones need to be regulated in some form, I'm afraid that they will be regulated with the goal of restricting their use rather than of ensuring people take reasonable precautions to reduce risk.

Of course we can agree on that. However I hope you will also agree with me in that the term "lead" for many things gets thrown around quite easily in the tech world.

What annoys me is I often see companies promote an inexperienced (due to age) developer to lead or architect or some other title when they are really not that at all. The company does it to keep the person happy [read: shut them up] with a title rather than pull out the company wallet and pay more. I know dozens, maybe even in the hundred+, people who were duped into that. Often because "it will look amazing on your CV!" or "we promise we will review your pay if things work out in 6 months" in the hope you forget about it or don't want to bring it up.

The problem I have with this is that it devalues the actual lead, architects, whatever the current trendy title is.

I look at it this way - A lead developer could be lead on a very important bit of software that somehow fits into something that could cause loss of life. If it were a structural engineer they wouldn't just be promoted to a lead architect after a couple of years in the game. Same with a surgeon or registrar or a judge or detective or ... the list is very long! Except in IT for some reason.

I do not mean to belittle anyone who is a lead developer and under 30. Good for you if you really are skilled and experienced enough to truly deserve that title, my problem is over the years I would say a good 90% of those "lead" somethings under 30 are not deserving of the title.
Also a heads up: Based on Amazon's price history you can usually get it between $40 and $50. If you see it for $60 probably worth waiting for it to drop.
The likeliness that we will develop a machine that we couldn't stop that also has the ability to destroy us and be able to survive without us is pretty slim. (Consider the amount of infrastructure that needs to be maintained and controlled.) And that's without considering that we would have to do this either intentionally or accidentally.

Unless we purposefully made these machine self-repairing. But then, why would we bother with that, when we can replicate them?
The idea that it's a social thing rather than a biological thing feels like a weaker claim. At the risk of sounding a bit reactionary, it seems a bit like claims relating to sex or race: there's a lot of pressure not to discover "natural" rather than socially-constructed differences.

After reading the article, I also wonder what correlation there is with high math achievements and being a victim of bullying, and how bullying effects the perceived social and empathy skills of a child.

There can be causation in the opposite direction, too. One of the reasons I was so driven to excel as a child was to prove that I was superior to those who bullied me.
This has been in beta for a while, the key thing lacking for our uses, at least with postgres, was full support for DDL.

The lack of "true" replication into postgres RDS instances is one of the things blocking us from fully using it.

One of the reasons we need these precise terms is that English is imprecise, and inadequate for this sort of thing. A more useful analogy is the one with formal logic, which can be made precise (Curry-Howard). I'd advise looking that up if you're interested in this sort of thing.

To sort-of approach your questions, ideas that you might find interesting are an unbound existential type T forSome { type T }, and also the fact that Nothing <: T for any type T (this is the principle of explosion in logic)
Ha. I've read it as "Fermat's Last Theorem" - guess that's the UK name.

A Pamphlet against R
Getting developers to write documentation is hard enough already.

Raising the barrier to entry to include learning complicated markup languages will chase them off completely.

I agree, it's far from perfect. But some documentation is better than none.
Signing commits bumps the size of the repo substantially. Not to mention that you then have to maintain your WoT connection in order to make sure people can verify that your key is actually yours (although you can use keybase for that).

Sorry, I should clarify. The core idea behind my app has never been done before; I made it because I desperately wanted it to exist. However, there are a number of independently-designed, $5+, iPad-only, fun-idea-type music apps that have had a lot more traction than mine. (One recent example is Fugue Machine[1].) I'm trying to figure out if there's some obvious flaw that accounts for the fact that apps like this tend to have several orders of magnitude more sales than mine.

Looking at my stats, it appears my main problem is that nobody knows my app exists. The # of views for all my media is just tiny, despite being on the front page of several subreddits, Product Hunt, and HN. Unfortunately, it seems this stat is directly tied to prominent writers talking about my app, and I can't seem to get that to happen. (My biggest sales boost by far was when a prominent music blog wrote a review for my app.) So I figured maybe something was wrong with the marketing pitch I usually send to publications. (Up to and including the way the app looks in screenshots.)

Yeah, this is why we have spam filters. Although, to be fair, I got my job at SUSE because of my free software contributions. So there is a benefit of including a real email (one that you check) in your commits.
> Moral of the story: higher N is always better.

This is true in a way, but finding and studying larger effects is often a better strategy. To some extent, why talk about something that needs huge N to get above the noise?

If survival is the goal, why not spend this few percent of world GDP to solve global warming. Plaster the deserts with solar panels.

Heck, we could maybe use the same tech to both robotically plaster the deserts with solar panels. Then send those finely tuned bots up to Mars to do the same thing there.
It seems history is repeating itself. This VR hype is going to be killed by lack of business innovation. We've seen this exact scenario with 3D printers. Awesome tech, but with a pricetag that has kept those devices from going mainstream. With VR, the guys are delivering innovative tech, but with the oldschool business model, trying to make money on the hardware. Sony would lead the game if they would lose money, offering a simple to use VR headset for $99 -$199, dominating the market and then make money on games and apps.

> replicating human voice with emotion and nuance (way more difficult than neutrally reading a text on Wikipedia)

How much of that difficulty could be skipped with a bit of basic markup, to indicate things like emotion (<sad>, <happy>), tone (<sarcastic>, <forceful>) etc? That is, how much of the difficulty is inferring the emotion/tone/etc from the text, as opposed to expressing it in the generated speech?
WebRTC is very promising. "Hello" in Firefox is surprising stable (although I know a lot of people don't like Mozilla partnering with Telefonica) but there are occasions my remote teammates would find using Hello give them better screen resolution and latency. In one case, I was able to do real-time troubleshoot with an end-user problem over "Hello." Typically we'd use Skype or Webex.

Does anyone know whether WebRTC is used in HipChat and Slack video feature?
At traditional restaurants and cafes, not every item on the menu is a profitable one.

Often some items are actually loss-leaders, enticing you to come in more often, or to pair it with a more profitable item that makes up for its cost.

Sometimes it is, even more, obvious that something is a 'loss leader'; such as at fancy dinners where they'll simply give you bread for free while you wait for your meal or bars where they give you salty snacks like popcorn to encourage you to buy more beer and not leave to have a real meal somewhere else.
Yep, I tend to agree with the author. For software documentation with complex APIs, something more robust than markdown is necessary. For the same reason that writing extensive in-line HTML+CSS markup is bad, relying too heavily on HTML as the "fallback" for styling and structuring things that markdown cannot handle is just not efficient.

Here's a quick cheat sheet... for the "why" of semantic styling your docs with something like .rst with directives makes for better overall integration.

> We can't even agree on carbon. There's no way we can agree on something like that.

Not with that attitude.

It's not so much that we "can't agree" but more that the main argumentative mode these days is sneering and insults, occasionally backed up by mob violence. No wonder people get stubborn about sticking to their positions.
You've actually touched on one of the benefits of RST with your complaint: there's no "magic" about Sphinx's "code-block", it's just a "directive" [1].

You can make your own directives which can optionally accept key/value parameters. This is technically superior to slapping blobs of HTML inside your Markdown, though I will concede that writing your own directives can be a bit tricky initially.

Also piggy backing this, I agree. I clicked and searched for my favorite podcast thinking I would find a rating!
> * Besides, are you seriously saying that "non-Western" cultures should remain poverty-stricken so that the "Western culture" can benefit from the resulting diversity? This is wrong on so many levels.

You hit the nail on the head here. The problem is not that we should or should not be helping them, but rather that we ACTIVELY and WILLFULLY base our economy on their continued poverty.

I think the best thing the US could do to end poverty is exit the world economy. The problem is that our standard of living and way of life is built upon the cheap labor of impoverished countries to produce the goods we consume.

I don't think western culture would benefit from such diversity. In fact the idea of diversity being a benefit is hinged upon the understanding that if western culture is not the most fit strategy, that there will be other cultures to rise when it falls.

The reason that I promote colonization as a more effective strategy then trying to fix problems here is simple:

- Attempting to fix problems here slightly improves the state of affairs, and reduces one of many possible causes for local extinction.

- Adding even one viable colony squares the chance of loss (that is an awesome improvement) and every additional colony exponentially improves on our likelihood of survival.

Correlation of 0.2 is negligible with any sample size. The potential for invalid inferences is only pronounced by a small sample size. A samples size of a thousand is much better. But with n=100, r=0.2 there is a bigger chance that local factors influence the result than that the observed association says anything about human nature.

I have a question about these hundreds-of-pages long proofs. Who can check such long proofs and be confident about it? To study a document of this size and advanced content rigorously, you would need years - and even then, it is not certain that you didn't overlook something. How can I ever be confident in such proofs until they are checked in, say, Coq or something?
How do you back all this stuff up?
Hardly. It has been about $40 pretty much everywhere for the last couple of years and gets frequent sales.
Yeah - this always trips me up too, since it's two colons, not the holy Python single colon, and it's "magic" on the preceding paragraph, not the code itself. Django docs written in RST avoid doing this style.

You can do anything you need to in RST, but there's just more friction involved.
This was the case many years ago because of limited search depth and simple evaluation heuristics. For example, chess engines used to be known to be overly attached to material; piece sacrifices for long-term compensation used to confuse them.

Those problems have since gone away. Anti-chess-computer tactics are dead. A human would be very happy to play a modern chess engine to a draw, and winning is not even in the discussion.

Did you just ignore the first few lines of argonaut's comment?

Recently, we also introduced activation functions in our neural nets, like rectified linear and maxout just for their nice mathematical properties without any regards to biological plausibility. And they do work better than what we had before.
The difference is JSX XML syntax is not a templating language but a functional one. In that sense it has nothing to do with PHP templates or any JS templating system based on string templating. it's XML directly in Javascript.
The line of thought was probably that they may reach a scale that can overcome these overheads since they don't have to pay rent or hire full time staff for every outlet.

It makes sense if you consider very early examples like Amazon which took more than 10 years to become profitable. Unicorns like Twitter and Dropbox are not profitable and are unlikely to become so in the near future, but they have reached a scale that their finances are relatively secure for now.
As I understand it, sociopaths/psychopaths are entirely inner directed. They either don't notice the damage they're doing or they power trip on it.

They literally don't see other people as people at all - they see other people as resources they can play with and consume.

Empaths may be manipulative, but it's hard to be a master of manipulation when you're aware your actions are making someone else unhappy and this makes you unhappy too.
These CPU/GPUs are doing very inefficient digital simulations of analogue processes. If anything, human brain has significantly more 'processing power' than Alpha Go when you restrict the computation to the activation of linear threshold units.
Birds also know how to dodge airplanes. The correct response to a collision course with a flock of birds—a situation I've been in on final more than a few times—is not to try to maneuver out of the way. Birds will always dive or climb as they close with the airplane.

Ask HN: Anybody know what type of hardware Vultr and DigitalOcean are using
Hi,

I'm trying to make sense of some benchmark numbers that I got while testing my indexing engine on $10/month DigitalOcean and Vultr VPS. Vultr performed a lot better than DigitalOcean and I'm guessing it's because DigitalOcean has more saturated servers, due to being more popular. If this is the case, one would expect performance numbers to equalize once/if Vultr becomes as popular as DigitalOcean.

If you have any information on their hardware specs, I would like to know. And if you don't feel comfortable posting the information here, send me a private email, which is in my profile.

Cheers

Only two sentences were about encryption. The others mainly covered the foundations, like kernels or MMU's, encryption depends on or can be bypassed with. You should look up TEMPEST Level 1 safes, PC's, peripherals, and rooms. That's just EMSEC part tgat requires all thst because physics fights us. Then, look up NSA Type 1 hardware and physical separation with Red/Black model to see how you start on endpoints. Rad-hard and fault-tolerant circuitry too where you'll see probabilities instead of certainties.

Add it all up to say that, outside a few products, your security mechanisms from CPU go crypto arent secure. Physics and intrinsic complexity work together to ensure this. Systems fighting all of it have less features, are heavy, more manual steps, less battery life, and cost several times more. Economics takes over there where physics leaves off.

"A priori there's only 1 correct plaintext, while there are limitless chipertexts of any given plain text (assuming arbitrary IV lengths and key)."

A priori there's electrical signals going through analog and digital circuitry that implements a form of it with malicious hardware, software, or networks connected to it. There's tons of ways to intercept or leak those secrets. These are not in the formal model of crypto. Once included, the picture changes considerably and leans my way.
Anyone configuring SSL on a web server should simply look at this: https://wiki.mozilla.org/Security/Server_Side_TLS

Mozilla has great recommendations in three categories (depending on what browsers you have to support). The intermediate recommendation will do for almost everyone. Combined with HSTS and a well-configured certificate it'll score you an easy A+ [1] on SSL Labs.

As a middle class person I signed up to two subscription services the other day. This is on top of my netflix, A-Prime and other common subscriptions. I realize they might not qualify to "on-demand services" 1:1 but seeing as the customer demographic is pretty much the same I believe on-demand services will always be viable as long as people demand things. And my god do some people demand things.
