If a transaction does not do this, it can be guaranteed to be insecure.

Maybe. Or maybe the merchant doesn't get paid for coffee at all (because faster blocktime means more orphans)!
Yes, thanks... corrected. So he would likely beat 26 good high school track runners set up as a relay, all by himself.
I wonder how can authors claim such great certainty in their results, after all, it is all based on number crunching. Some floating point error, and similar is bound to creep in...
> I'd be willing to pay a lot for access to a similar cooperative archival-quality music library not subject to any copyright/licensing issues.

Oh my yes. I currently pay Tidal $25/month—$20 because I refuse to believe that in 2017 it is economic to stream 4k video but not lossless audio. And tack on $5 for a family member.

But I am continually annoyed when I'm listening to an album and I expect a transition into one song, but instead the album skips forward a track or two. I can only assume this is because they've lost distribution rights on a particular song for some infuriating reason.

After the advent of streaming music purchases, and about the time subscription services started, Steve Jobs opined that nobody would want to rent music when you could own it. At that time, I thought that this was old man Jobs stuck in the past. And it sort of was, based on the popularity of Spotify and evidenced by Apple's capitulation. But... I find myself increasingly frustrated by being a serf and being totally at the whims of profit-driven licensing schemes.

And this is why I want something similar to what.cd (I didn't even know about it until it was dead). I'm happy to pay for what I use, but FFS, the idea that we're letting chunks of our culture die because we lack the legal mechanisms to preserve it all makes me just crazy.
There are VA-approved schools, as the article notes: https://operationcode.org/code_schools

> Some code schools do accept GI Bill benefits — longer-standing ones that have made it through State Approving Agencies, which work on behalf of the Department of Veterans Affairs to decide which programs can use GI Bill money.

So it can be done, and responsibly. I guess the only thing that's left is to increase the number of seats at VA approved schools.
Do many of those mummies have living children? There are people alive today who survived the sinking of those ships.

Most Egyptian mummies come from a culture that was staggeringly remote and ancient - to Cleopatra, to later Byzantine culture, and certainly to Egypt after the Arab conquest... which was 1400 years ago!

Bronze age remains from Europe are not treated differently, you know. Those are also in museums around the world.
If you'd want to argue for the effect, you could say the winner gets sponsors, better food, better trainers, better doctors, less time for fund raising, more time for training, etc.
"Better" is circularly self-defining, because it really just means "More successful in a given niche."

You don't really know what's going to be more successful in a given niche until it becomes obvious.

As you say, there's no reason it has to mean "Worked harder", "Was technically superior", "Practiced more", or any of the other things it would mean in a less arbitrary world.

You can often increase your odds of success with all of the above, but a 1% change - whatever that means in practice, and however you're supposed to measure it - is always going to be swamped by effects outside your control.

Unsure of what you are looking for, exactly, or in what context/availability: public, premium or cloistered data. "New" is often old tech evolved. A few off the top of my head:

Nielsen boxes have been collecting for decades. Then came adapters: TiVo, cable/sat receivers, connected game consoles, streamers(roku). Now, the TVs themselves.

Black boxes on planes have long been a thing. OnStar has been collecting on vehicles since 1996. Insurance companies offer their own black boxes for a few years now.

Dedicated GPS devices uploaded data when updating maps online. new units most likely evolved to real-time broadcasting via wireless, but that is an assumption.

Retail/vendor membership cards, registration and extended warranties were seemingly created for analogue data collection.

Other sources: CCTV systems, RFID tags, Dept Transportation cameras: intersections, plate readers, speed cameras, freeway cameras, pneumatic road strips/tubes.
It's absolutely possible. Admittedly I'm still running 2.1.18, but I just tested it there and it still works.

Imagine two swimmers the exact same age. They can swim competitively from age 21--30. There are 10 meets per year. The question is this: after each year, what is the probability that swimmer A has more medals than swimmer B? The resource for swimmers is time.

> I know my smartphone always has the right time

Unless it's dropped in the toilet, or runs out of battery, or the software gets compromised, or you simply lose it.

Reliability is it's own feature, a thing that often gets overlooked in software development.

Software is that which is disposable enough not to bother building hardware for.
I completely agree. These questions should be the ones you ask before starting any kind of business, and regardless of your pricing.

It's really hard to convert a user that's already using a competing service just on price because they're probably already used to it, too the time to set it up, etc.

If you give them a little improvement it'd be as hard, but if you give them something they just can't get anywhere else you might have a chance. At that point the lower price isn't necessarily even a consideration but rather just a nice to have for them and probably a growth challenge for you because you'd be undercutting the revenue potential of a feature no one else has.

On a side note - price is what many founders believe potential consumers base their entire decisions on. While that's true for some products, it doesn't mean that it is for you. It's always best to figure out how to reach users first, then experiment with pricing.
From my experience this is normal for embedded development; particularly for consumer electronics. Part of the reason some developers in this space have to wear so many hats is that the pace in consumer electronics is unforgiving. I don't think my current employer is unusual either.

Hopefully, the number of frameworks at the top, and the size of your individual programs are relatively small (so that 1-3 aren't nightmares by themselves).

In my experience, 4-5 are seldomly the problem (thanks Linaro!). I suspect the ratio of C to C++ is significantly larger in embedded systems though.

In general, PowerPC/MIPS/ARM toolchains and drivers are not as mature as x86/AMD64. 6-8 tend to occur because CPU vendors usually have their own "blessed" toolchains and BSPs that have diverged from their upstream projects. Fortunately, this means that it's often the case that someone else has already fixed the problem. It's just as often that a driver has not been tested for your use-case since the last time that particular driver's infrastructure was refactored inside the kernel. Or... you wrote the driver and made the mistake (or it might be something from 9/10).

9-10 happen because we're often using hardware that is new and has not had all of its errata discovered yet.

When products need to ship, we're regularly going through this stack. I've seen every one of these, even in just the last 4 years.
We observed this rule recently and called it the Pareto Cubed principle[1], or the 50/1 rule.

It's even more counterintuitive than the 80/20 rule until you really understand the nature of power laws and unequal distributions.

Once you win a gold medal - you're more likely to attract better trainers / facilities / sponsorship. That can be used to build an unassailable advantage.
You made such a long comment and could not name one thing that ethereum can do but bitcoin cannot. People using that decentralised exchange have either lost money during the ethereum forks (or haven't because oasisdex is not really decentralised if you look closer?)

>Ether is similar but at least has lower transaction costs

Myth. Do the math. Ethereum is much more expensive at similar parameters.
It's story telling with no scientific basis - fairy tales for grown ups.

Pareto is valid, but getting from Pareto to "You only have to be a little bit better to win everything" is first-order nonsense.

Still - the author has books to sell. So there's that.
I love your description because each word designates both problems and solutions. History books will go further and further: "WWI was triggered by an assassination in Sarajevo", "WWII was born in the black Thursday", and the next events "find their source in the solitude of some men with a computer, and we couldn't solve that. Solitude kills, after all.". Assuming the next event is related to alt-rights, of course.
I'd rather re-read books that I've loved, and still have a lot to gain from, this year

For me ngrok spares me all the talk with infra team to have the public port exposed and the setup of a test server just to for a mere 10 or 20 calls I need to receive from some new service I am checking.

I use it to prototype webhook entry points, and only need to receive a few call to have a quick confirmation I receive what I expected from the docs.

Once I have enough info I can start building a more solid project and jump through all the hoops to have it on a real server with a subdomain and a public facing interface and all the security needed etc. I'd just hate to go through the whole process first, only to discover the service is unusable for my purpose, or the data I receive doesn't make any sense.
It's not a natural science. If you restrict sciences to whatever you believe a natural science is, you'll kick out some useful, predictive and fruitful subsets of the natural sciences out too.

So maybe we should let that old meme "if it's not done in white lab coats, it's not a science" die.
I think so. Ten years ago I worked at a startup doing entry level support but I did not have programming skills.
I dont use to apply for jobs because I'm not graduated. But I did apply for a job that required some excel skills so it was not very hard for me ad I now have medium programming skills. But the HR responded that there were candidates better qualified than me.
I didnt want to apply to that job I just asked her if Im overqualified for the job and she called me and begged me to send a CV. I will never ever again apply to HR.

I've used ngrok for a while now, and I love it. I used it just last night to test out some webrtc stuff I was doing. Was able to get friends from around the world on video chat served from localhost within seconds.

It's also super handy when building webhooks, you can use the unique URL to test out apis without having to deploy anything. I can't rave about it enough.
> If I could easily tear down the entire tunnel from the remote client to my hidden service, then the delay to rebuild the tunnel would mitigate the resource exhaustion attack ...

This seems like a great suggestion for Tor. I hope the author will get in touch via the mailing list and see what solutions might be possible.

In the text they say they use high-precision floating point calculations to reduce this type of error:

> At first, using the obtained initial conditions, we checked the 137 periodic orbits by means of the high-order Taylor series method in the 100-digit precision with truncation errors less than 10^−70 , and guaranteed that they are indeed periodic orbits.

> Besides, we use the CNS with even smaller round-off error (in 120-digit precision) and truncation error (less than 10^−90 ) to guarantee the reliability of these 27 families.

They do reference some software (e.g., "dop853"), but I'm not familiar with the details of those ODE solvers.
I'm not sure if the other debug tools mentioned offer this, but AQTime Pro:

https://smartbear.com/product/aqtime-pro/overview/

has an allocation profiler that can be used to track down this sort of problem. You can take allocation snapshots while the application is running to see where the allocations are coming from (provided that you can run AQTime Pro against a binary with debug symbols/info).

I'm not affiliated with the company - just a happy customer that has used them for years with Delphi development.
Yes, the product being cloned in this blog post, Lumio, was pitched on Shark Tank.
Now that I think about it, I wonder if this is an area where technical & financial investment from a volunteer geek corp, plus librarians & libraries, could create something?

I don't know enough about copyright and how they apply to libraries. It seems to me that they're the right repository for this kind of thing.
Taking a principle and lauding it makes not an insight.

There is no rationale given for the 1% rule e.g. why not 10% or 0.1%? There is not statistics behind the 1% rule. Yes there are "the winner takes all" situations but the article neglects diversity and other negative feedback loops e.g. in fashion the winner may succeed only to be swept away by a counter-revolution trend.

The ocean is quite a different place. Wrecks are often debris fields, and not simple plots of land.

It's not appropriate to wax indignant about remains that may have all but disintegrated into unrecognizable mud. These are not organized places, like the parks on land with paths that people walk.

Consider the wreckage of the Titanic:

What is your definition of "science", and why is economics not a science in your view?
Nice. I have been wanting the due date feature for a long time on workflowy. There seems to be no development for workflowy beyond what was available a few years ago.
Nevertheless, you should still see a shrink. If you don't like the stigma of mental illness then see one who calls themselves a 'life coach' and say you're going for advice on improving your life.
Don't rely on libraries, just sort yourself out with learning the basics :)
The numerical methods used for this kind of calculations are engineered to compensate numerical errors (floating point and errors inherent to integrators).

They take advantage of a priori knowledge about the laws of physics, in particular the conservation of mechanical energy and angular momentum. Predictor-corrector is one family of methods. Other methods rely on convergence as timesteps change.

There is a lot of literature on numerical integration applied to celestial mechanics and new methods being released every year. These methods are tailored to this problem space.

How to Put Fun and Satisfaction Back into Your Work
I'd argue that Roku/Amazon Echo/Nest thermostat/dropcam are the most successful IoT things, but we don't necessarily think of them as "IoT" and they stand alone as their own product categories, but in the more canonical IoT categories:

Things I've bought:

- Cheap Wifi bulb from TP-Link that I can turn on/off w/ voice to avoid stumbling around in the dark

- Harmony Hub so that I can tell my Google Home to turn on the tv/change the hdmi input/etc

- Temperature sensor

Things I want:

- Air conditioner w/ intelligent control. Besides voice-activated laziness there's probably energy savings to be had with better control algorithms, eg incorporating WiFi sensors or weather predictions.

- Actually wireless meat thermometer. I'm waiting for the MEATER kickstarter to ship and read reviews.

- I'll buy an IoT lock once the price comes down to about $50.

Things I want someone else to do:

- My subway line to have real-time tracking of trains. It really shouldn't be as hard as the MTA folks try to make it sound.
Spot on. The experience level of a developer is directly proportional to how fast he/she assumes that the problem is in someone else's code. ;-)
The paper has a section on this, around the end of page 4, which is really interesting. The short version is: They compared their double-precision results to extremely high-precision Taylor expansions (with theoretical 70+ digit accuracy, and calculated in 100+ digit accuracy), and found that they matched to the accuracy you'd expect.

That doesn't guarantee that the orbits are perfectly periodic, I suppose, but it does suggest that the orbits are stable with respect to rounding errors up to those you get from using doubles.
I wonder how many users are actually aware that Instagram is owned by Facebook and then think about what that knowledge would do to public opinion and uptake.

A portion of users enjoy using Instagram because they consider it a FB "alternative", and that they're privacy is at less risk by diversifying social media platforms.
I think your answer is the best so far.

Making blanket statements about it being a good or bad idea isn't very helpful. The OP made a very generalized questions with almost no detail. Certainly not enough to provide much of any helpful advice. However, ultimately it is going to be dependent on how interested the developer is in making it work and their timeframe.

Underestimating how much time and resources even the simplest of projects require is common - and that is if your management skills are really good.

Historical sites are normally somewhat maintained and preserved. They are also quite often seen by tourists who are interested in those sites.

Most sunken ships, they just sit there and nobody wants to take responsibility and maintain them so that no oil and fuel gets into the ocean. Furthermore, there is little to see. Sure there is some historical information on them but we should save those otherwise the ocean destroys them (surely but slowly).

If those sunken ships were properly maintained, I would also call those scrapers thieves because they take something that belongs to someone else and it has value to them. But since most are just sitting there, waiting to slowly decay.

The only things those scrapers should be held responsible for, is when they damage a tank or something like that which pollutes the ocean (and there should be resources on how to do that safely). But then again, those fuel tanks will leak at some point anyway (they won't last forever) and it should be our responsibility (as humans) to make sure that does not happen.
More than impossible, it's the wrong thing. Speakers in a room don't move with your head when you turn it. By the time the sound gets to your ears, it's already had an HRTF applied - the natural one. The thing to go for there is wavefield synthesis, not any flavor of HRTF.
You're describing this viewpoint: https://en.wikipedia.org/wiki/Gene-centered_view_of_evolutio...
however I don't think it's really an accepted (in terms of evidence) theory that explains all evolution. I think most biologists think that evolution selects at multiple levels (although likely the underlying processes are much more complex than just that).

After all, no real visible phenotype is truly based on a single gene, but rather the dynamic interplay of hundreds of gene products over the course of the organism's development.
After reading such an article it is easy to see this pattern everywhere. And, sadly, it is also easy to see all the areas where I am in the group of people who come in close second. With the article in mind it would seem rational to quit endeavors of those kind cold turkey. In reality, it's not so easy. Maybe you don't want to give up b/c of all the time you've invested or b/c you're really passionate about what you're doing or maybe some fellow people still keep encouraging you and don't want you to stop...

This makes me wonder whether there is a good general exit strategy for those situations. That is, a method to reorientate as quickly, painlessly and promising as possible. I worry that's a too abstract way to think about it, though.

In multiple places, especially towards the end, the author touches on negative feedback loops as much as positive ones. That said - in a zero sum game for resources, a positive feedback loop is in itself a negative feedback loop for others.
>, but if being "better" was the only factor, Betamax would have beaten VHS.

Betamax was "better" than VHS if you only compare 1 dimension such as "picture quality". However, if one also compares other dimensions such as:

+ recording time: VHS records 2-hours vs Betamax 1-hour

+ licensing fee: JVC less expensive than Sony royalties

... to combine pq+capacity+price into a composite score, VHS was "better".
