This was not a technical issue. Everything worked exactly as designed. A large market sell order reduced the price to a level that triggered other sell orders (a combination of "stop-loss" and forced liquidation for margin positions) in a cascade. This was a flash crash that was over within a few seconds, so other markets did not react.

The issue is that there are a lot of inexperienced traders
on GDAX right now and they were recklessly trading on margin and/or setting stop-loss orders without understanding the possible consequences.
> Another common theme I noticed is when the man in question stays in the gray area where individual incidents aren't clearly over the line and might not qualify legally as sexual harassment, but in context and in aggregate it's clear why a woman would feel very uncomfortable.

This seems like a slippery slope. I can imagine malicious but careful predators who constantly test boundaries in a conscious effort to achieve a sexual goal. But I can also imagine a poor socially awkward guy who just has a severe crush, but is doing his damnedest not to say or do anything to act on it- and a woman who would be particularly sensitive to his unwanted romantic desire.

Both would be "incidents that don't cross the line but in aggregate make the woman feel uncomfortable", but the latter deserves understanding and _perhaps_ a calm discussion, but definitely not punishment.

I'm just saying, even the gray area has a spectrum- but any policies people come up with to handle this, would need to establish a threshold higher than just "a woman felt uncomfortable around a specific man", or perhaps a gentle grade of responses.

Amazon’s idea for a massive Drone Dock
Try keeping a solid satellite connection while holding your dish in your hands.

Now do it on a boat, trying to compensate for waves and exhaust gases from a 27.4 tonne rocket.
This is tinfoil hat nonsense. The feed goes out for a couple of seconds due to the vibrations caused by the incoming 10-story booster retropropulsing its way to the deck. It always comes back after the rocket has shutdown.
Or you know... maintaining a high bandwidth satellite link on a barge in the ocean with three rocket engines pounding down on it is difficult and not particularly high priority. They have never not shared footage afterwards, and we've got footage all the way down live once or twice (not with a three engine landing burn mind you, since this is the first time they tried that).

The man in charge of this (/u/bencredible on reddit) has also explicitly stated that it's not intentional.
You can also buy many premium Android phones at half or a third of the price of an iPhone depending on the specifications you want. I also don't know where you get this idea that cheap Android devices have a significantly shorter lifespan. These phones don't just suddenly die or expire by a certain date. I have an old Galaxy S2, a phone released in 2011, that works well to this day.

Tangentially, I have been struggling, for several years, with Safari being extremely slow at opening sites, compared to almost instant loading in Chrome. Anyone seen this?

I'm always on fast networks (100mbps or so), but I find myself waiting 4-5 seconds or more before Safari even shows signs of connecting, even to things like Google and YouTube. It seems to be limited to HTTPS sites, and seems to have been introduced when Apple started using a new MacOS TLS/SSL framework called something like "Apple secure transport" (I forget exactly) a few MacOS versions back, and it's almost certainly not DNS (I get the same issue with Google DNS as with my provider's).

I don't even know how to debug this, since I don't have a command line client that goes through the same TLS/SSL framework code as WebKit. Curl is fast, for example.
And I'm one of them. We don't want to alienate the already small number of people who develop Free Software. I would rather see companies who violate the GPL comply rather than seek damages. Actually bringing a suit, in my mind, is basically the nuclear option.

> I've always had tinnitus since I was a child and just thought the world was like that.

I'm exactly the same, although I do know what caused it for me. My mother's then-boyfriend was an abusive piece of crap who used to haul me around by my ears whenever he felt angry. Sometimes he would throw me head first into the wall by pulling my ears hard in that direction, then use the back of my head for subsequent blows, so it could be neurological rather than an audiological phenomenon. (You'd think she would've put a stop to that, but you would be wrong - she stayed with him for a few more years.)

Normally the ringing would stop after a few hours, but I remember the day that it never stopped. I got so used to it that I tuned it out and completely forgot that the world was ever silent.
Always hilarious to me how many educated humans will actually go argue that they are p-zombies rather than face the paradoxes of consciousness.

I guess all I'll say is, physics seems capable of explaining the evolution of our universe and e.g. the emergent complex phenomena of solar systems and planets and such. Physics and the other hard sciences do not seem to lend a lot of clarity as to how a self-organizing piece of the universe developed into beings that believe themselves to be conscious, believe they in some sense have the power of mind-over-matter, and in fact have constructed a globe-spanning civilization that appears to demonstrate the ability of billions of minds to understand to some degree themselves, each other and the universe, and to willfully bend matter to suit its purposes. aka Hofstadter's "who pushes whom around inside this cranium?" question.

We have not come anywhere close to constructing an artificial system with similar capabilities nor to understand how or why they arise in our own brains. It's presumptuous in the extreme to hand-wave away this conundrum with an "information processing" metaphor.

Thoughts on Trading Commodities-Linked Cryptocurrencies
blockchain is a concept. It can refer to the actual implementation seen in bitcoin, ethereum and others. Or it can refer more generally to the algorithmic backing of crypto-currencies.
It's literally in the article.
Its a simple fix. The venue has to control the name on your id with your ticket name.
It has to be personalized in some way and it seems reasonable to keep your "real ID" away from the blockchain account. Even though the venue can identify your wallet on entrance... so there is a small design flaw :)

You're mobilizing a different argument here - since we can't construct it, there must be some transcendent property.

I can't see how that evokes any of the paradoxes of consciousness.

I mean, 200 years ago, humans didn't have a plausible idea how the sun work, should they have assumed God was behind it?

Edit: and humans certainly broadly have a decent idea of the physics and chemistry that gave rise to life even if the function of the brain is so far beyond us. So we're certainly not confronting life as something wholly unexplained. Some parts are still beyond us, some things we don't know yet. But un-knowledge usually isn't evidence for any specific thing.
That's my favorite kind of art. It really is art done for it's own sake, for the creativity of it. It's its own motivation.
“Does It Have Buttons? Is It Touchscreen?” – Long Term Inmates Using Tablets
If you want to rip in to Apple or Google or Uber for claiming they should have a pass for using privacy tech, feel free. Understand that this is distinct from most research on differential privacy.

The US Census collects demographic data about as much of the population as they can manage, and releases summary data in a large part to support enforcement of the Civil Rights Act. They have a privacy mandate, but also the obligation to provide information in support of the rights of subpopulations (e.g. Equal Protection). So what's your answer here? A large fraction of the population gets disenfranchised if you go with "avoid sharing the datasets".

You end up with similar issues in preventative medicine, epidemiology, public health, where there is a real social benefit to analyzing data, and where withholding data has a cost that hasn't shown up yet in your analysis. Understanding the trade-off is important, and one can come to different conclusions when the subjects are civil rights versus cell phone statistics. But you are wrong to be upset that math allows the trade-off to exist.
'Blockchain' is literally the least interesting part of cryptocurrencies and their applications. its a boring flat file structure that is an artifact of needing many clients independently deriving a shared ledger, nothing more and nothing less. the interesting part is how you can bootstrap issuance of a new asset by incentivizing participants to assist in maintaining a specified computer network in exchange for cryptographically-{verifiable|enforced} units.
It's technically correct what you are saying but it's a "businessy" way of looking at the landscape. Developers (and orgs even more) should try and always expand their area of competence, not limit themselves to one area (not saying they should be experts in all).
A good piece of tech should make you want to learn a language more (RabbitMQ/Erlang, PostgREST/Haskell, Pandoc/Haskell/).
You can get lower than that even, if you need a lot of data.

Buy a used SC846 second hand, that costs ~$900 inclusive of rails and a SAS2 backplane upgrade. Then buy drives. You can get 8TB drives for ~$230 (Seagate Archive or shucked Reds) or $0.027/GB. Add cheap colocation for say $70/mo.

Assuming the hardware lives about 5 years, total cost is $900 + (70x12x5 = $4200) + num_gb x 0.027.

If you fill all the bays you're looking at 192TB for 5 years for $10284, or $171.4/month or $0.90/TB/mo.

The why I think is quite clear from an evolutionary standpoint. Whithout self consciousness all our actions would only be triggered by surrounding events, hungry - eat, tired - sleep and so on. But with the ability to reason about our self we can for example find and cure diseases long before we feel any pain which is an evolutionary benefit.

> Can you give me a theoretical example?

I can give you a practical example. I do a lot of photography/videography in my spare time (not professional, have never been paid for it). I shoot RAW photos on a Sony A7RII. Every photo is ~85MB and I can shoot 700 photos in a day. Assuming I shoot one day every weekend, that's 3TB of data a year (that's actually a close estimate when I account for vacations and such too). Then there's video. I own a Panasonic GH5 and record on an Atomos Ninja Inferno, which outputs 4K 10-bit ProRes video at 60fps. This consumes ~1TB per hour and I tend to store it for archival purposes since it only costs ~$25 to do so for pretty much ever.

For a less extreme case, one of my old school teachers has been doing photography as a hobby for ~15 years. She's amassed ~10TB of photos over that time and currently stores them on piles of HDDs and a few spindles of DVDs scattered around her house.

And yes, I absolutely accept that I'm an outlier but any service that offers an unlimited plan is explicitly advertising itself to outliers. They're not putting themselves out there as someone with a 1TB, 2TB, 10TB or even "enough for 99.9% of people!", they're saying that they're giving storage with zero limits.

Your buffet comparison by the way isn't a good one. A buffet isn't truly unlimited, it has a time restriction, a condition that you can only eat what you take, you can't leave with it and the fact that a human being can only physically eat so much. They haven't defined a limit but there certainly is one.
Sadly this book gets the description of statistical significance completely wrong.
Not particularly surprising, given how unintuitive reasoning behind p-values really is, in Jeffreys words:
"What the use of P implies, therefore is that a hypothesis that may be rejected because it has not predicted observable results that have not occurred. This seems a remarkable procedure."
BRANDING IN HIGHER EDUCATION
AWS bills instances hourly; both Azure and Google Cloud bill by the minute (albeit with a minimum of 10 minutes). For data analytics that you want fast turn around time for, this ends up being a big deal: a 30 minute job is literally 2x less expensive than "round up to an hour". This also shows up in auto scaling of services, since a standard business day of traffic obviously only has a fairly short actual peak combined with what is ultimately fairly short term load.

Disclosure: I work on Google Cloud.
> I believe that the PDP-10 (well, some versions) had the first few memory locations equivalent to registers.

Essentially. Actually the registers were addressable as the first 16 addresses in memory for all models. For the PDP-6 and first PDP-10 (model KA) the registers were fast semiconductor devices (DTL, as I believe it predated TTL) while the rest of memory was literally core (convenient for when the power went out, as happened occasionally in Cambridge -- whatever process was running died since the registers were lost, but everything else was in core, so the machine could just be restarted).

Since they were addressable you could run code out of them, like bootstrap routines or some deranged TECO code I once wrote). On the other hand any word of memory could be used as a stack pointer (two addresses fit in a word, so one half was the base and the other half the depth).

It was quite a RISC-like, highly symmetrical architecture for its time and a pleasure to program. I still miss it.
It's a "dialect" (sort of) of Ocaml, with all of the beauty that is its type system and Functor (not thing.map, parameterized modules!) that can compile to JavaScript via Bucklescript.

There's a bit more to it. Proof of work hashing and ledger consensus rules and difficulty targets and fee schedules and forks.

It's still all standard bachelor's degree algorithms, and I agree with the gp that it's not the interesting part. The interesting part is using these algorithms for social consensus on value.
I too am perplexed by this. I sadly believe this trend will continue until some serious regulatory consequences are implemented.

Why do you keep persisting in quoting that 30% number when it's been repeatedly demonstrated to be misleading?
