I certainly would not be doing that, I could see myself working for free in my current position if I could just do the SW related stuff, but all the crud I seem to have to deal with from marketing/program management types because they can't be bothered to learn our product would be right out as would any tier one customer support.
I'd love to be able to just fix all the known bugs that never get attention because they're not understood by management or implement automated testing on a larger scale.
I don't understand why people with significant wealth would want to run a company or organization rather than work on the project directly, but each to his/her own.
Um, because senior leadership is basically just fixing bugs and optimizing space/time/resources at the scale of the company rather than at the project/code level?
Now, most senior leaders suck at this just like most programmers suck at their jobs. That's just a fact of life. But if you luck into a good leader...
Maybe they listen to you about the crud you have to deal with from program management types. Then they think hard, figure out the correct metrics, run a few tests on current projects, come up with a better implementation, and get it adopted (i.e. pushed to production.) It takes a year, but the organization is better in the end (well, except to some project managers who were doing the wrong thing to begin with.)
I pray god that there will be one more bank run. I made quite a lot of money last December, when zerglings stormed banks and currency was traded at 15% spread.
Currency was trading at more like a.015% spread. Retail customers got a 15% spread.
You just crypto-sign records and publish the (possibly encrypted) ledger.
If the entire DB was encrypted and published every time it was modified (many times per second) how could that possibly be a better solution than a blockchain? If you only encrypted and published the diffs, then wouldn't the chain of diffs pertaining to a single item be functionally the same as a blockchain, other than being scattered and more difficult to verify?
You're totally correct. A classic DBMS is just an efficient way to map a series of immutable transactions into a current state that can be queried efficiently: in it's most pure form it's just a complete transaction log, an initial empty state, a mapping from state+transaction->state, and a bunch of caching to aid in querying. So the transaction log is exactly equal to your chain of diffs.
Is the chain of signed diffs the same as a blockchain? Not quite. They are both chains, but transactions in the diff chain are not revokable (they are signed and can be upheld in court, etc,) whereas the blockchain transactions only become effectively non-revokable by consensus (requiring time and lots of compute power.) So, signing is much faster and cheaper than consensus. Scattered is second reason signed transactions are better: I only need to keep my copy of a transaction to prove it happened, blockchain requires I go out and find the consensus longest chain to prove the transaction is recorded. So, signed is safer and faster again as long as I can keep my own data.
And you don't need a blockchain to fix the relational db tampering issue. You just crypto-sign records and publish the (possibly encrypted) ledger. Sign-and-register is technology that works and has been around for long before computers even existed.
The only thing blockchain solves is the double-spend problem. And that isn't an issue for WallMart's solution.
If you think scientists are worried because burning oil releases heat, and that heat is causing global warming, you are badly in need of a science education.
Walter Bagehot, the famed British constitutionalist (writer of the English Constitution, a must-read for those who want to understand the Westminster Parliamentary system)
Given that the English Constitution is not written, I will now discount everything else you are babbling about.
Yeah, this. OK so I know it's 8AM on the US west coast where my daughter lives, and in Japan where my MIL lives, and in the Czech Republic where my parents are. That still doesn't tell me a damn thing about what time it is over there - can I call them? Are they home? At work?
This is an idiotic solution to a problem that doesn't exist.
It really helps all the people living at the exact North Pole.
NASA has how many years experience in this area and how many has SpaceX got?
You Luddite!
Elon Musk has the expertise in the 100km/hr vehicle space from his Tesla work. Elon Musk has the expertise in working with high-ISP energy systems from his battery and solar city work. Elon Musk has the expertise in the 500km/hr vehicle space from his Hyperloop work (including low-cost bridges and tunnels and vomit bags.) Elon Musk has the expertise in reusing the booster tin-can in rockets (getting 200lbs of rocks back from the moon was so expensive because we forgot to make the first stage reusable.) Elon Musk has the expertise to go to Mars because he said so, and the turn-around time of the rockets is just a few days.
So, sit in the luxury space capsule and watch the blickenlights while he fuels that puppy up.
Agreed. Very few people (police included) wake up and say "I want to be a jerk today, escalate lots of situations, get complaints filed against me, and be in a bad mood all day 'cos I didn't abuse someone enough."
Once they see being reasonable, and taking the professional stance, works as well or better than abusing the other person, they internalize the new behavior pretty fast. They probably go home feeling more professional and happier, camera or no camera.
People are starving while Gate$ hoards 78 billion dollars in cash. That makes sense.
Somewhere, a computer has { BillGates: 78,000,000,000 }. So what?
Interest rates are effectively zero right now. Hoarding is obviously not a way to make money, nor does it impact anyone's ability to borrow money and be productive.
Hoarding corn, or gold, or Titan-X graphics cards, or elephants, or opera singers would be a dick move. Hoarding money is pretty value neutral.
Bitcoin as an idea is very interesting but, in actual function, it's a scam. I wanted to learn more about it a year ago and so bought some mining ASICs. It doesn't take long before you realize that your magic money printing device was sold to you at a cost that means you will invariably lose money. Which makes sense. If I have a magic money printing device, why the hell would I sell it to you instead of running it myself?
Um, because of reality? In this case, cost of capital:
If I can make a machine for $900 that generates $100/year forever, I get an 11% return on capital. If I can sell it for $1000, I get an immediate return of $100, and can build another machine and repeat the process. At one per day, I make $36,500 in my first year.
If the risk free interest rate is around 3%, the second plan is worth 10x as much as the first plan.
IF we are talking about probabilities.... Why on earth did you put guns on your list. Gun deaths are pretty rare overall, even with the weekly tallies from places like Chicago... I believe you are more likely to drown than get shot...
Well, in the USA, fatalities due to traffic and guns are about equal (around 30K/year, or 2 per state per day.) Note guns is 1/3 homicide and 2/3 suicide.
Be fearful! There might be strangers sleeping somewhere in a property near you.
I bet the hotels are lobbying for this. Airbnb is one thing that is pushing the cost of visiting New York down.
We're fearful because we live in shared doorman apartment buildings. We usually keep our apartments unlocked 24 hrs
And that's a very idiotic thing to do, regardless of the trust you have on your neighbors. This is specially true if you live in a big city. Convenient or not, you are just asking for a Darwin award. Wise the fuck up and learn to lock your doors before a tragedy hits you.
Thanks for explaining how we in zip code 10023 are behaving idiotically. I'm sure your low-crime, high-education, high-income community that dwells on Darwin awards and cowers behind their locked doors can teach us how to build a nice society.

We're fearful because we live in shared doorman apartment buildings. We usually keep our apartments unlocked 24 hrs (for our own convenience, and because we know and trust our neighbors, and because old buildings have quirks like single elevators that jam and so you hop through someone's front door to get to the back door elevator bank.)
We'd like to keep that and not have to switch to living in a hotel-like environment.
It's likely also a violation of First Amendment freedom-of-speech.
No, the 1st amendment only applies to the government restricting your speech.
Doesn't that encompass the notion that you can't force folks to say what you want them to say?
Private contracts can say all sorts of things, including "if you say X, penalty Y applies." If you're a company employee, or a sponsored athlete, you probably don't want to say X. In general, however, a judge is not going to like compelled speech, especially if it is due to a bullshit "we reserve the right to amend the terms of this agreement" change.
Everyone that keeps saying that the autonomous cars are just around the corner all live in big cities. To get to the point they work without a steering wheel (aka manual mode) these companies have to solve for rural driving. Until the cars can reliably drive up a back woods, rocky, single lane mountain road they are worthless.
70+% of Americans live in cities or suburbs. And they produce almost all the GDP. So it's hardly "worthless" if driverless cars have a problem with places that people rarely need to be.
What kind of simulation would give up empirical evidence of its simulationness?
1. Due to limited computational resources, the simulated universe would be granular or "quantum". 2. To limit computation, reality would be held in a fuzzy probabilistic "superposition" state until it is actually observed, similar to how virtual reality skips the generation of hidden polygons.
Both of these are actually true in our universe, ergo, we are a simulation.
3. It would also need an upper bound on how fast information can be transferred, again to limit the amount of computation at any point in space-time. Oh, our universe has that too.
Game 2, move 37 was amazing. The commentator had already pointed out the issues with the two stones trapped to the lower/middle left and the loose group to the lower right. This move linked everything together in a light way. This was an "ear-reddening move."
This is the first time a machine beat human using a very similar way as people's thinking.
Despite the name "neural network", there is nothing "very similar" between the way AlphaGo works and brains work.
That seems correct. AlphaGo is playing go at a level beyond that of humans. The take home point seems to be that brains aren't really competitive and are probably a dead-end technology.
The board can be in one of 81 states (well, less, cos some are illegal.) The number of paths for the initial board to all ending boards is in the hundreds of billions.
