Yeah, in Australia it's currently overnight between banks (but generally instant from one account to another within a bank), and they're bringing out a new real-time payments platform over the next few months so you will be able to transfer instantly to anybody knowing only their 'pay ID', which can be a mobile number, Australian Business Number (ABN), etc.
This won't stop the regulations coming their way. Facebook had the chance to prove they could be trusted but squandered it and may have ruined it for the tech industry. They know this and it's why they hired Washington lobbyists.
Who do I trust, the guy who was told “It is impossible to reuse rockets” by all NASA engineers and built a company around it, or the analyst described as follow:

> Warburton, who spent his career before Wall Street at the International Motor Vehicle Program — a partly academic, partly commercial organization based at MIT — wrote that "automation in final assembly doesn't work."

It doesn’t even matter since it’s not public money. Which makes me wonder about the analyst’s intent: Tell people not to invest? Do people not know Tesla is super-risky? but if they succeed to obliterate this anchored rule that automation doesn’t work in the final assembly, isn’t that a superwin that stakeholders dream of?

Friends who invested in Tesla didn’t “invest” so much as “donated” money for what they think is a good cause. And perhaps because it’s fun to hear the NASA chief say “I had asked my engineers and they told me it wasn’t possible”.

I’d pay for that kind of fun.
OTOH, also consider local rent control laws, which often only allow a rent increase below the CPI. the longer you stay the more you save.
Ok, I see I read the figure 3b wrong (only glanced at it before). I extracted the data from their extended figure 5a:

dV sigma R_major
-4.16 16.41 -3.98
10.55 3.41 -1.97
15.03 7.25 -1.85
-2.24 5.12 -0.74
1.17 5.75 0.29
-14.39 5.97 1.16
-40.39 11.3 1.52
2.24 6.61 1.58
-3.52 13.43 4.49
-1.39 10.23 6.77

Then ran this simulation in R:

# Used for biweight midvariance calculation (r.bw)
require(asbio)

# Utils:
## Simulation function:
### "For a given value of sigma_test we generated 1000 samples of 10 velocities,
### distributed according to a Gaussian of width sigma_test. The ten velocities
### in each sample were then perturbed with errors, drawn from Gaussians with
### widths equal to the empirically-determined uncertainties in the measured
### dispersions.
run_sim = function(nSim, n, sigma_test, err){
replicate(nSim, rnorm(n, 0, sigma_test) + rnorm(n, 0, err))
}

## Clean up the biweight midvariance output
r.bw2 = function(x){
as.numeric(sqrt(r.bw(x)))
}

# Scraped data roughly matches what is reported in paper
## MAD (~4.7)
s_obs_nmad = mad(dat$dV)

## biweight (~8.4)
s_obs_bi = r.bw2(dat$dV)

## RMS (~14.3)
s_obs_rms = sqrt(mean(dat$dV^2))

# Run simulation to test sigma values in .1 km/s intervals
## "Using the biweight estimator, “measured” dispersions sigma_obs,test were calculated
## for all samples. If the value 8.4 is within the 16th – 84th percentile of the
## distribution of sigma_obs,test then sigma_test is within the + /-1 sigma uncertainty
## on sigma_intr. This method gives sigma_intr = 3.2 (+5.5, -3.2) kms^-1."
sigmas = seq(.1, 30, by = .1)
nSim = 1e4
out = as.data.frame(matrix(nrow = length(sigmas), ncol = 2))
colnames(out) = c("sigma_test", "s_obs_bi_percentile")
for(i in 1:length(sigmas)){

# Calculate biweights for each sim result
sim_res = run_sim(nSim, 10, sigmas[i], dat$sigma)
sigma_obs_test = apply(sim_res, 2, function(x) r.bw2(x))

# Output sigma_test and the percentile of 8.4
out[i, ] = c(sigmas[i], ecdf(sigma_obs_test)(8.4))

# Print progress
print(out[i, ])
}

# Check which sigma_test values are within the accepted percentile range
out$check = out$s_obs_bi_percentile > .16 & out$s_obs_bi_percentile < .84

# Plot the results
png("results.png", width = 960, height = 960)
plot(out[, 1], out[, 2], xlab = "sigma_test", ylab = "Percentile(8.4)", panel.first = grid())
dev.off()

I get that their observed sigma_biweight = 8.4 has percentile of p = .0146 for sigma_test = 20 (https://image.ibb.co/ncRF27/results.png). In their terminology that would mean it is just within the 99% CI, ie had odds of happening of ~ 1/70 if MOND were correct.

I believe I replicated their results since it had percentile of p = .6336 for sigma_test = 0.1 and p = .1607 for sigma_test = 8.6, which matches to their sigma_int = 3.2 (+5.5, -3.2) using 16th - 84th percentiles result.

Where did you get 1/100,000?
I agree it is semantics, but it shouldn't be in my opinion.

While it will never happen, I would prefer to call yourself a restaurant you would need to prove that you had hired qualified chefs and that you were producing all the for you sell.

It's a major gripe of the industry that people like me do the work to create real quality food, and then get lumped in with places that use premade crap.

I should probably stop my rant now, I could go on for a while haha.

PoW is just one of available consensus algorithms. Blockchain doesn’t imply decentralised consensus, you can run it on paxos, raft, authority round or something else, especially for internal, private or semi-private networks. What you get is trail log with proofs that’s immutable and strongly protected against temper.
Blockchain is a shit database concept. It's use as a currency is one of its best uses. This idea that blockchains are a good database is an absurd myth. Blockchains are useful specifically for doing distributed consensus, and almost nothing else. Currencies are one of the best applications of distributed adversarial consensus. There are others, but currency is pretty near the top of the list.
You must be a lawyer. Dude, can we keep the laws simple? I mean, I wish I could sue manufacturers of jeans (hate seeing someone’s crack when they bend), I hate toothpicks (super useful but sometimes I hurt my gums), I hate carpets (sometimes the static electricity creates a spark that hurts my hand when I attempt to open a metal door), and I hate brooms (they never quite get all the dust gathered). I also would like to sue the makers of Fortnite as I was one of the last two and a glitch froze my gun for two seconds, which allowed my opponent an unfair advantage which created pain and suffering for me.
Is it just a resistor, or is it one of hundreds of possible resistor depending on factor X? USB or any connection should be simple - you know, like code. The more exceptions and options you add, the harder it becomes to properly implement it. This is exponential, too, not linear.
What voltage is the 100W coming through at? If it is low voltage, that is gonna be a really beefy cable... At 12V that is more than 8 amps. 5v is 20 amps. That is a lot of current to send over a typical USB cable...
A neighbour of mine has a spare piece of waste land in an industrial area on the edge of a nearby town. He has opened a storage facility using shipping containers.

You have to be careful of this - airlines look for people using the so-called "throwaway ticketing" strategy, and reserve the right to close your frequent flier account.

I suggest three interesting exercises:

- design a QA process for a software product. How important is "blame" vs team learning? What are the tradeoffs of a blame-oriented approach vs a systems oriented approach?

- build something using AWS or App Engine infrastructure that makes you have to work around the various constraints imposed by the system designers. Consider how to make a system reliable when building it using "unreliable" services.

- consider a Marxist interpretation of the US legal system. I'd argue that it constitutes a reasonable systems oriented critique, and makes it clear how (at least for me) pre-existing biases made it at first seem absurd. I suggest this mainly to highlight how biases can impact systems thinking. The QA process example is also deeply emotionally charged for many engineers but should not be.
When my grill gets hot, I scrape the surface with a straight-edged spatula to clean up. If the grill looks super grungy, I hold the spatula at an angle and scrape between the grill wires.

This does not yield a shiny silver grill, it does however leave a lot of the grill’s seasoning whilst removing charred particles that would stick to the food.

Is it too surprising that BTC is in Contango? As the article explains: BTC has energy cost to "mine". So in effect, BTC in the future is worth less than the promise of BTC in the future.

Future BTC requires a LOT of energy to create. So the Contago simply is correlated to the energy costs.

Unless there's a "bigger problem" here that I'm missing??
Yeah, it baffles me why they didn't mention any alternative in the article!

Does it make a difference how the wire brush is made? I know of two types, let me call one flat and the other wound. Flat is where wire bristles are inset into a flat head on a handle. Wound is were the bristles are held by wires twisting around (which often have a triangle head for BBQ brushes and are made the same as typical bottle brush).

Are they equally bad?
Maybe it's USB-C because of future usage requirements, that they envisioned they might need USB-C to interface with attachments (VR headset? New GB/DS generation?).
I mostly hear it described as Internet 2.0, or Web 3.0. However, analysts are starting to talk about Blockchain 2.0 now; this could probably fill the role of Internet 3.0.

Also, the way I deal with flare ups is to restrict the oxygen availability by covering the grill.
>EEs who can actually read a damn spec sheet properly...

I think this is the hardware equivalent of expecting programmers to write bug free code on the first try.

Most of the time when a programmer wants to implement something a little complex and a little outside their expertise, they use an external library. Likewise, EEs will often buy a chip produced by a third party manufacturer and use that to handle it. But the abstractions available to EEs are often a bit more leaky than those available to us programmers, since they are more constrained by the laws of physics. and as a result that third party chip is still harder to use than a software library.

You can have a blockchain without miners. https://en.wikipedia.org/wiki/Proof-of-stake

Now I agree that a lot of ideas for how blockchain will be used are just unnecessary and stupid, but there are some good ones as well.

You mentioned file storage but actually I think blockchain could be useful for this. Allow me to elaborate.

I don’t want to rely on Dropbox or Google or any other single company for the long-term storageof my data. And I don’t want to accidentally upload unencrypted data. And I don’t want a single company to decide what platforms they will support.

I want an open protocol and a nice open source client. Different people have different wishes. For me that would be far more attractive than the centralized storage you are suggesting, because it’s not just about the servers and the storage it’s also about the people and the software ecosystem around it.

And besides, if I gave like hundreds of GB of data to one company then they could easily start charging me more in the future and I might not be able to do much about it. With a distributed system I think there is a better chance that competition might drive prices down more.

And that’s just one kind of use-case. There are more as well.

I think blockchain in general is cool and also I like projects that aim to make worldwide payment be really fast and cheap and for the banks to hold less power over my money.

This is a major gripe I have with the modern service/subscription-based economy.

I give major props to companies that reward loyalty. IntelliJ, for example, offers discounted rates the longer you've been subscribed. It works for them because it's an incentive to never let your subscription lapse, and it rewards the dedicated end-users as well with cheaper prices.

The question that no one bothers to ask is, "What problem is this technology solving that can't be solved cheaper and just as effectively with 'traditional' technology?" When you look at it this way I think the realistic use cases go way down.

As these people are in the minority, the companies can afford giving them the goodies - the "suckers" foot the bill regardless.
Yes, businesses try out different things and some things stick and some don't. This doesn't even have anything to do with technology. Businesses use computers because some idiot in a suit read an article.

Many companies are making a lot of money from implementing or integrating "Cloud", "Big Data" and "ML". They're not fad technologies. Blockchain hasn't done anything yet so should not be lumped in with them.
And this jury, that made the decision about APIs being copyrightable (in the US), that made this into "a clear loser for Google" in 2014 were also a dozen randomly selected laymen with no background in law nor programming?

Which part of "let's find a small group of the least qualified people to decide on billion dollar cases" ever seemed like a good idea to anyone?

Then there's the judge, who has a background in law but NOT in programming.

Then there's the lawyers, who have a background in both (assuming the expensive lawyers G and O can afford), as well as years and years of practice influencing the decisions of small groups of laymen.

It's hilarious that they were able to copyright tetrOminos (a mathematical name) and call them Tetriminos(tm).

I honestly think they have greatly relaxed trying to take down clones as long as they are not distributed on any platform like Steam or an app store. There are plenty of clones which copy certain versions of Tetris identically and TTC doesn't seem to care. Games like Tricky Towers are able to go around the trade dress, but sadly Spaera had to make changes.

It's very sad that the spirit of the game is a homebrew personal project that was freely distributed became one of the most controlled games ever. All they do now is make money off the name while release garbage. So people make their own games, not to steal from them, just because their games are so shit and there's a market who wants a better game.

I guess the the previous poster is implicitly proposing an international treaty on the atmosphere (edit: maybe creating a new UN specialist agency). Of course, there are already a number of other treaties in this area and while some of them have worked reasonably well (like the treaties to protect the ozone layer by eliminating use of CFCs), others have been fraught with difficulty.

There are already international treaties on water rights, even with dispute resolution mechanisms in some cases, so maybe these mechanisms could be extended somehow to water rights in atmospheric water. (Not that this is by any means easy in the case of surface water.)
