No, those aren't real problems either. Problems are experienced by humans. Humans willing to pay money for solutions.

Actual problems are things like "I want to buy this candy bar," or "I want to fly to New York in August and I need to pay for the ticket." Those are problems Bitcoin, as "a purely peer-to-peer version of electronic cash" [1], was intended to solve. It didn't.

As far as I can tell, the main problems blockchains "solve" are things like, "I would like to run a Ponzi scheme and not go to jail." Or, "I would like to hype something and make a lot of money off people." Or, "I would like my consulting company to bill a lot of hours." Or, "I would like to gamble on price fluctuations, and gold isn't volatile enough for me." But I wouldn't call any of those real problems in the sense of being things where solving them is positive sum for the society as a whole.

I would be happy to be proven wrong, of course. Blockchains are a cool technology. But I've spent nearly a decade asking for actual customer problems that are demonstrably solved better by a blockchain. I haven't found one yet.

The backwards compatibility users require (myself included) holds back innovation, in so many ways.

The problem with any non-standard keyboard is it being non-standard. The biggest problem is a different layout than Qwerty (though its a bit more complex; e.g. Azerty is standard in Belgium, Colemak is only marginally different from Qwerty, whereas Dvorak is completely different).

If the layout sticks to the defacto standard (Qwerty) then you can argue less is more. However, there are some minimum needs and once keys have different positions compared to a dumbed down Qwerty keyboard (without keypad or keypad + arrows + the other [6 + 3] keys on the right). It also depends on what you're used to. Having used the keyboard on Nokia E71 and Nokia N900 and Nokia N810 I lost a lot of CLI speed just from factors such as: non-standard keybinds (e.g. requiring combos for standard Bash and Emacs keybinds), non-standard amount of keys, small keys, with not much travel.

There are many examples mentioned in this thread. Some membrane, some mechanical, but generally full size keys just without keys such as spacebar, enter, tab, caps, alt, etc. The only keys which can be removed from a keyboard without compromising UNIX CLI usage are caps lock and "function" (Windows key etc). With the notion that caps lock is already rebinded to escape by Vi(m) users.
I would say that one can only speak of a breach if data from this has reached people that shouldn't have it.
DXA scan is pretty much the only way to do it accurately. Calipers, "smart" digital scales, and comparing yourself to diagrams online are all very poor methods of checking bodyfat and should be considered to have somewhere around a +-10% error range.

I found a guy in my city doing DXA scans for $80, I usually go get one done every six months or so.
I hope you like math, because an official or unofficial Ph.D. in Physics has enough math to make a Math Ph.D. cry.

Here in Argentina many universities have the recommended books and the class problem for each course in the web page, so you can "take" the course for free if you read all the theoretical material and do all the homework. It's not official but it's a good guideline for which books to read and in which order. Don't skip the elementary courses. I guess that in the US some universities have a similar free content.

The problem is to get feedback about the questions and the homework. I don't know if there is a newbie physics stackoverflow.

You can try to work with some research group. Sometimes they need a programmer. Some can pay you, some expect you to work for free, some don't want to explain anything to an stranger. Also, most groups don't work in fancy topics, most topics are more boring.

And don't expect a very modern software practices, many people use Fortran with a code style created before Fortran 77 and no version control (each paper is a folder with custom single use code).(Note: Modern Fortran is very fast, sometime faster then C.)

Anyway, if you want to work as a programmer for a physics group, I think that taking (formally or informally) some course will be good so you can talk to them and understand what they are saying and how they think.
What new construction? Where? For whom?
this experience could depend on the field of work you are in.

Being fluent in statistics/linear algebra & discrete math/category theory -- makes you 'head and shoulders' above others, when it comes to assessing industry trends, and deciding if some are applicable to your work.

Having those skills, does not mean, of course, that they would compensate for the lack of creativity, hard work, risk taking, constant year-after-year-self study, or inter-personal & presentation skills.

Some examples:

Being able to understand word-vectors and related techniques, for chat boats, or compliance -- is very helpful.

Being able to reason about degrees of security of data published on 'immutable databases' or 'data streams' -- is useful, again in compliance (as in making records tamper-proof).

Being able to design protocol/interaction across systems with context-free grammars -- is helpful, in protected against certain types of attacks. I would say this is reasonably relevant for systems that are exposed on public internet.

Being able to read reasonably recent (or 20-30 year old) papers on Differential privacy/homomorphic encryption -- allows you to reason how effective your data protection strategy could be (again relevant for compliance).

Obviously, understanding financial service models, performance models of distributed queuing systems -- require understanding of the maths I mention above.

Being able to recognize where in your, even basic business workflow or database/state management -- there is an appropriate place to introduce finite-state-automate (to reduce number on 'unanticipated conditions') -- is also helpful.

Being able to recognize database mapping through the lens of category theory, improves how you could design your data models (because right at the time of designing your data layout you are also thinking about transformations between them -- which is basic need for non-trivial business system integration).

Opposite to the above post, I always feel that I need more math background that I have. And I would love to go back in time and significantly beef-up my education in that area.
It's worse than that because immutability and lack of human judgement is also the killer feature that smart contracts offer over good old fashioned paper contracts and binding arbitration agreements. Any attempt to make maintaining smart contracts manageable is almost by definition going to undercut one of the main rationales for wanting to use them in the first place.
What's worse is they don't even need a shred of evidence to take your stuff.

In some states, having more than $10,000 in cash on your person is automatically considered "evidence of criminal activity". That means that the police, just by seeing that you have more than $10k in cash, can simply seize it and then force you to spend your time and additional money proving that the money didn't come from crime.

And, of course, every cent of the cash they take goes to their own department, so they are incentivized to look for cash during traffic stops just so they can literally commit highway robbery...

It's also not unusual for an officer to record that they found $15k in cash, only for the person they seized it from to call foul, stating that they had more. Since there is literally nothing protecting the citizen in this situation, they are left without any legal remedy, and the cop gets to pocket your cash for his own illicit purposes.

This is a system that encourages corruption with the justification of profit.

I've found the kiosks to be laggy and inconsistent in accepting touch input; any orders that have multiple different items take longer for me to key in at the kiosk than to verbally express at the counter.

But having the ability to customize items to your exact specifications is very nice; reminds me of the old Burger King wrappers that had icons for ingredients around the edges, with the intention of their inclusion or omission for custom orders being marked, but it's a practice I've never observed being used.

The McDonalds in-app ordering and pickup is a superior experience to the kiosk, but it needs location to be on.
Sure.

Your definition of torture is a guard tossed a sandwich out of arms reach for a 3 hour ride because he's a jerk.

> Productivity and wages broke lockstep in the 70s, wage growth has lagged employment growth to an unprecedented degree since 2009

I certainly believe this on a national scale, but I've never seen these stats properly adjusted for globalization. A billion people were lifted out of poverty in the time period mentioned. It doesn't seem to me that these traditional indicators are wrong, they've just been corrected for a global marketplace.
I am French so I can respond to your comment.

In France, tipping is not mandatory and if I do it I usually leave 1 or 2 euros in change.

Waiters in France do not have to pay for their own health insurance.

They can actually afford to go to the doctor and get help if they need it.
No risk of medical bankruptcy here.

Waiters get paid the minimum wage in low-end restaurants but make more money in the upscale ones.

Waiters dont need to rely on the patrons' generosity to pay their bills.

"That said, listing that as the reason for termination is not legal. I did do my job in a professional sense. Freely sharing what I believe to people who listen is free speech. You cannot legally be fired for your opinions that do not affect your work; at least not as the listed reason."

I'm generally on your side here, but that statement is absolute bullshit. Your employer also has the right of free association, and can choose to no longer associate with someone who states they wish they could commit violent acts against their coworkers, regardless of how serious those statements are.
I am most concerned about your last point. I do not believe that student loan debt will be the cause of the next recession but it will definitely be a massive compounding factor after it begins. A bunch of people in there 20s defaulting on loans is going to create one hell of a mess.
Its supposedly was the SOP for USAF gate guards at RAF Checksands in the UK.

And I suspect try and run a gate with a vehicle at Sellafield would lead to a similar response from the Nuke Police.

Totally. I wanted one of those so bad - thanks for adding it! :)
The basic reading would be, that unless the Constitution defines a power of the federal government, that power resides with the states and citizens. As mentioned in the Wikipedia article, its addition was basically CYA, as it was and is true regardless of its enshrining within the Constitution. As such, its existence does not really mean anything beyond what the Constitution already meant. It just provides a handy shortcut to say, "the federal government should not have had the power to enforce this on the states."

This is actually a rather important principle, and most people don't realize how many federal laws that work at the state level use funding carrots rather than criminal-punishment sticks for enforcement. For instance, the penalty for not following the unpopular and eventually dismantled "No Child Left Behind Act" was that your state would not receive federal education funding.

> The Act required states to develop assessments in basic skills. To receive federal school funding, states had to give these assessments to all students at select grade levels.

In the eastern hemisphere, this kind of place is called an Australian style cafe.

Old joke: some Australians take a taxi from LAX to their hotel. As they get out, the driver asks, "Your tip?" "Our tip is, live somewhere with a minimum wage, mate!"
The full text reads:

>The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

What, exactly, this means has been a matter of ongoing debate for much of the amendment's existence. Some of the more fervent states' rights advocates have considered it a hard check on the power of the federal government, while at other times it has been considered little more than a truism.

My own personal read on it is that it defines the nature of state and federal lawmaking power, from the perspective of the constitution. Federal law is strict. The constitution allows it certain specific powers and subjects it is allowed to govern, and it must stay within those. State laws, from a federal perspective, are permissive. The constitution bars certain powers from the states, but anything not banned they are allowed to regulate.

In practice, this means less than it might, because the constitution's powers allow the federal government a lot of room to regulate and govern. At the state level, incorporation doctrine also limits their powers a fair bit.

In terms of judicial history, the 10th is one of the less significant parts of the Bill of Rights, becoming an issue in court far less than, say, the First Amendment (freedom of speech/press/religion) or Fourth (limits to search and seizure/ warrant requirements). On the other hand, it has come up more often than the Third (forced quartering of troops during times of peace).

> (And if the relationship between development and ops has broken down to the point that each one is trying to work around rather than with each other, you're already screwed. The rest is just details.)

IMO 90% boils down to that, regardless of what technology one side or other wants to use. If Ops is trying to push Dev to use a particular technology or vice versa. This happens whether you're talking Docker or a particular programming language.

Either side will see their preference as solving the problem of doing their job in the best way possible. If both sides are deaf to the problems seen by each other, it becomes a problem.

Honestly, the place where I see this stuff more than anything is when developers want tools that make them more productive, because the technological merits are harder to convey.
Quickly add send-feedback for electron apps
The send-feedback electron-element allows you to quickly add send feedback functionality into your electron app. It allows you to set it up in a way you can either send a request to backend with report, or redirect to a site or just send the feedback to a email address.

The UI is fully customize-able although it have a pretty good UI out of the box.
It is the first electron-element in the electron-elements github org. We hope to add more
electron elements which are web custom elements, if you have one open a issue at https://github.com/electron-elements/electron-elements to move it into the org.

Without wading into the politics, as I understand it, had he to do it over again, taking his inheritance and simply investing it in the S&P 500 --- like any common schmoe --- would have produced superior returns.

That seems like the definition of an "unsuccessful businessman", but I'd be interested in the semantic interpretation where it doesn't.
For mongo, with existing features or the new transaction feature, is it possible to access the ids that are generated during the update, to use on subsequent updates, as references, without needing to return to the dB client to process or build objects? Could be across collections also
Reviewing the history, the Xscale/StrongARM sale to Marvel went through in June 2006.

The original iPhone was released in June 2007 with a 620 MHz Samsung ARM.

That was awfully close. I wonder if Apple was consulted on the sale, and what else was privately said between the two corporations.

Intel certainly had the iPhone in their grasp. The Wiki says that the Blackberry Bold used an Xscale PXA930, the Torch used a PXA940, and the Xscale IOP348 was hitting 1.2GHz. Unbelievable that Intel walked away, after pushing several mobile products with the leading smartphone manufacturer of the time.
What about all the existing clearing houses we have today? How have they managed to survive without Blockchain?

My thoughts exactly. Thomas is, clearly, more on the law-and-order side of the current court, and his opinion (or the part of it quoted in this article anyway) sounded pretty negative on the practice, at least as it currently exists. It doesn't seem like he would have written in favor of taking the case if he wanted to stay with the status quo. But, I am not a lawyer.
Of course it's documented fact. And the CIA had a comparable program called CHAOS. Moreover, read up on JTRIG's use of sigint to conduct psychological warfare, as revealed by their own documents (GCHQ leak from the Snowden archive)-- smearing people online, destroying reputations. Presumably, they are only conducting such operations on radical terror leaders, but how do we know? And what's to stop them?
There's a very good chance you're not testing your body fat correctly. I've gotten several friends, including bodybuilders and various athletes to get DXA scans done... pretty much every one underestimated their BF% by 5-10%. Including the ones who swore up and down by their personal trainer's caliper measurements, the BF testing machine (the electric handles one) at their local supplement store, etc.

I'm 14% BF and a BMI of 20... looks to be right on point.

Sadly no. There are some issues still that may not ever be addressable with how Firefox's WebExtensions currently exist.

Some things have Bugzilla tickets to fix in a future release, but something just won't be possible as it stands today.
From what I've heard from insiders at the BigCos who are buying many of these 'blockchain solutions', the main advantage of blockchain is that it is a sexy buzzword which convinces management to pay for BigCo to update/solve some unglamorous problem they weren't willing to throw money at beforehand.

'I presided over the digitization of all old records' isn't something an MBA type necessarily wants on their CV, so they won't push for it no matter the value to the company.

However 'I lead a team implementing a solution to digitize and store records on the blockchain' is how the MBA type gets a promotion/new job offer and how the technical guys can get the budget to do important stuff that was otherwise too unglamorous to be prioritized...

But with non-reversable transactions, you still have the trust issue. Now it's that the customer has to trust the merchant, that they're not going to completely rip them off.
>Commerce clause means that if something moves from state to state, that sure does seem like a Federal matter

To clarify (as you no doubt know, but other readers might not), this has been taken by courts to mean that any type of good that is traded between states is fair game for federal involvement, even if the actual product in question never has and never will travel outside of the state, or be bought or sold whatsoever.

The article describes a lot of the buildings a fortress-like. I actually don't have a problem with that - in the event of a catastrophe, I want my telecommunications to keep working.

The rest of it - splitting data traffic and sending a copy to the NSA - I'd like to see how any international traffic is being sent through a land-locked city like Dallas, which should only have domestic traffic in it. Which the NSA shouldn't be looking at.
I find it hilarious that they made this into a talk! There must be something more to it?
This is solvable without blockchain though. Supply chain tracking already happens at the moment without Blockchain.

Thankfully they have a dark gray version as well [1]. Just the price at 220 USD seems... expensive.

How noisy are these switches?

> We need to come up with solutions that aren't just possible, but cheap

Renewable energy sources are already cheaper than traditional nuclear energy, in many parts of the world already cheaper than fossil sources, and rapidly getting even cheaper:

https://en.wikipedia.org/wiki/Grid_parity

And at the same time, Westinghouse had to file for chaper 11 bankruptcy because ... well, nuclear power does not seem to be so economical at all.

As an interesting side note, both nuclear power as well as renewable energy sources have the cost structure that almost all investments are up-front, while the relative amount of running costs is very small. Because in a market system, the marginal cost of production per unit determines the market price, and the market price is therefore close to zero, both technologies have the problem that they actually need subsidies and incentives to be created. In other words, while renewable power sources definitively need incentives, nuclear power also can't exist without huge subsidies.
