On second look, MicroG won't be a good option at all.

It requires signature spoofing.

(i.e. security to be broken in various ways. Opens it up to all sorts of other attacks, plus to even install, forces rooting the device, or running Xposed, or applying dodgy kernel hacks and prevents using verified boot, which is a sensible security requirement).

I had the privilege and joy of meeting several of the team at the Internet Archive who actively police for this kind of content as best they can, while maintaining the openness of their service. They're cheerful, honest, hardworking and energetic people. There's few groups I'd feel so happy to support.

Maintaining an open and freedom-loving service in the face of abuses is incredibly hard. It's an incredible disgrace how badly these attackers have misunderstood their targeting.
Technically it's possible to leak a Box without using `unsafe`, since the std::mem::forget function is not marked as an unsafe function (because it itself can't cause memory unsafety, and because there are (incredibly convoluted) ways to create an equivalent function entirely in safe code).

However, the only reason you'd have for using std::mem::forget would be because you're doing unsafe things elsewhere in the program (as discussed at http://doc.rust-lang.org/std/mem/fn.forget.html ), so you're correct that in practice there's almost always an `unsafe` block somewhere that's the culprit.
That depends on what you expect to get out of them.

* If you're looking for DDoS mitigation, use basically any of the providers that offer it on a network level - it's really not necessary to have access to HTTP traffic to mitigate attacks. Also, don't run Apache - it's notoriously vulnerable to various low-bandwidth attacks.

A non-exhaustive list of "real" mitigation providers (note that I am not making any particular recommendations):

- Voxility
- X4B.net
- Akamai (formerly Prolexic)
- Level3 (formerly Black Lotus)
- Psychz Networks
- CNServers
- Sharktech
- OVH (not as a separate service, but their entire network is covered)

You'll want to avoid anything HTTP-specific (as it will be prone to the same privacy issues as CloudFlare), and opt for layer 3/4 mitigation only.

Another option, if you're running at a larger scale, is to purchase mitigation appliances and just set up your own mitigation infrastructure. This will not be cheap and require some serious connectivity, but beyond a certain point it'll be more cost-effective.

* If you're looking for a WAF, run one on your own backend server(s) and/or loadbalancer(s). There's no benefit to doing this remotely, really. Even something relatively simple like ModSecurity will cover a wide array of problems.

* If you're looking to save bandwidth: don't bother. Traffic costs virtually nothing nowadays, and saving a few dollars by having another provider cache your assets hardly outweighs having the privacy (and potentially security) of all your users compromised. If you find traffic to be expensive, you should probably look for a different provider - some providers (like AWS) notoriously overcharge for it.

* If you're looking for better performance: CloudFlare doesn't really provide that to begin with. There's an extra hop for non-static assets, and depending on the location of your server and users, it can actually slow things down. If your performance is really critical to the millisecond - and chances are, it isn't - look into hosting providers that offer anycast.

* If you're looking for DNS hosting: plenty of options. Many providers offer it for free if you host with them, Hurricane Electric offers it for free regardless of where you are hosted (http://dns.he.net/), and if you need an SLA, there's Rage4 and Route 53. Pretty much every DNS hosting provider uses anycast.

* If you're looking for magic SSL/TLS: Use Caddy (https://caddyserver.com/), which is a HTTPd that will automatically set up and renew certificates for you through Let's Encrypt, as well as greatly simplifying TLS configuration. It's essentially zero-effort.

Trying to outsource this to a third party (like CloudFlare's "Universal SSL/TLS" does) defeats the point - it means that the third party can see all of your traffic, all the while providing a false sense of security to your users; they see the padlock, but their traffic is not secured end-to-end.

In short: the only correct place to terminate TLS is on your own servers.

* If you're looking for something else that CloudFlare offers: Feel free to describe it, and I'll suggest an alternative.

It's not like a bathtub. (And let's ignore time dilation.)

Imagine you have a large mass (sun) moving in a straight line, and an object (sensor) 1 light minute from that mass. The gravity from the sun takes 1 light minute to reach the sensor - that would mean that the sensor is attracted to where the sun was 1 minute ago.

That can't work - it violates all sorts of conservation laws.

Instead what happens is that the gravitational force itself is ALSO moving in a straight line! So when the gravity from the sun reaches the sensor it attracts the sensor to where the sun is now because both the sun, and the gravitational force, are moving together.

This works out very nicely.

But what happens if the sun is moving in a circle? Otherwise known as accelerating?

The gravitational force can't know what the sun will do in the future (that it will move).

So as the sun moves it forces the gravitational force to change - before the force was moving in direction a, now it's moving in direction b. This change in the gravitational force is known as a gravitational wave.

This wave, because it is accelerating, has the ability to impart change in other objects, otherwise known as imparting energy. So gravitational waves can carry energy! Potentially huge amounts of it.

(And since they carry energy, they themself have mass, and therefor gravity, but these second-order effects as they are called, are too confusing, and weak, and everyone ignores them.)

Back to the black hole - as it orbits the other black hole (as they orbit each other), they change direction very very rapidly, causing huge gravitational waves - the waves steal energy from the orbit, causing the two black holes to fall into each other with smaller and smaller orbits, i.e. a spiral.

My problem is this: Near a black hole time dilation is enormous, huge gravity, plus huge velocity. So to an outside observer the black holes appear basically frozen and don't move. If they don't move they don't make gravitational waves, so we should detect nothing.

I have no answer to this question.

I doubt they expect to make that much money from it. I suspect their motivations are actually moral. If it has to exist it may as well be as good as possible. There's no reason to subject pot-heads to nasty chemicals. They can afford to over finance the service philanthropically. I wouldn't be surprised if they considered the potential consequences to their image and decided to go along with it anyway.

You can grow a RAID-Z “vertically” like this, but can't grow it horizontally by adding disks… which is frustrating.

(I'm also frustrated that it's not possible to change redundancy within a vdev — e.g. go from RAID-Z1 to RAID-Z2.)
How do you figure? If the single disk has bad data written to it, it contains bad data. If the RAID has bad data written to it, it contains bad data. Either way, the bad data is bad, because it was undetectably corrupted in memory before being written out.

No, it was a first mover, with what was in hindsight an obvious innovation.

When you're a second mover, though, protectionism is absolutely necessary. Observe American heavy industry during the 19th century, the two Japanese economic miracles, any of the Asian Tiger economies, German auto firms...

If your goal is to grow a domestic industry against powerful established players, you should absolutely not optimize what is good for consumers.

But it's also very important to understand that there is a ceiling. There will be a point at which Silicon Valley startups will stop increasing salaries. People will no longer be able to buy a house. Demand will drop and so will prices. If this occurs at the same time interest rates rise, people will not be able to afford to renew their mortgage and the house of cards will tumble. If the prices are really high and nobody has paid off any of the capital on their properties (as in London in 1991/92 and Tokyo where people had multi-generational mortgages), people will not be able to afford to sell because they owe more than they can sell the house for. But they will be forced to sell because they can't afford the new mortgage. There will be a rash of personal bankruptcies and unless someone steps in, very, very nasty things will happen. In London, the Japanese bought up the land (ironically just before their bubble burst). In Tokyo the government stepped in.

I don't know when, but everything is lined up "nicely". Ridiculously low interest rates, sky high prices, insane salaries. Even if SV companies move to a cheaper location to save on salaries it could trigger the collapse. Seriously not looking forward to a time when the fed raises interest rates to protect a falling dollar... Etc.

That's not necessarily a off-by-one error, but a broader problem of audio synthesis, which you can generally deal with by applying low pass filtering. For example depending on starting phase of a sinus oscillator multiplied by a simple linear volume envelope (1.0 -> 0.0) you will get a click at the first sample, which is loudest at multiples of pi/2 for the starting phase (cos). So you need to low pass filter the envelope to get a quick fade-in of the oscillator without click. How you do this and how that sounds is up to you. The original hammond organ similarly got some nice analogue clicks as initial transients because of this 'problem' as a side effect btw, in digital its much harder and expensive to make nice curves. De-clicking an audio engine properly is certainly an important and sometimes frustrating task.
Another example might be "sort -u" (because you can get the same result from "sort | uniq"). There seems to have been a pattern where people decided that if "foo | bar" (or "bar | foo") is a common enough idiom, they could or should create "foo -b" to mimic it.

The Guardian does do native advertising [0], and I find their labeling policy unclear. This case study [1] by their native advertising division, Guardian Labs, highlights videos that are very clearly labeled [2] but also an article [3] that doesn't seem to be. Their policy on commercial content [4] seems to suggest that everything is clearly labeled, but at least in this case they either didn't follow it or ignored the distinctions in the case study.

If these cameras had a warrant attached to them, there would be no question that the locations should remain secret - I fail to understand why its so hard to get a warrant for this kind of surveillance - but I am at least somewhat understanding (its kind of obvious) why the camera locations should remain a secret.
