Bitcoin and blockchain enthusiasts have been claiming that bitcoin (or etherum) is going to take the world by storm any day now, yet all I ever see anywhere are big claims (revolutionizing payments, disrupting remittance, ending wars, freeing the people, destroying the banks etc, ad nauseam) with very little substance and lots of scams, frauds and dead-end ventures. Dark markets, internet gambling and a handful of other novelty and niche communities can extract genuine utility from bitcoin, and that should continue into the foreseeable future, but the general population just has no use for it. None. Despite all the hand wringing about having to endure the treachery of big banks, pull style payments, and entering long credit card numbers, bitcoin is still harder to use, even harder to keep secure, and without any guarantees, assurances or consumer protections. Bitcoin is an interesting novelty at best, and everyone knows it, even many bitcoin enthusiasts.

Now, in recent months, we're suddenly hit with a bevy of stories about big name financial brands and famous VCs pouring cash and research into the blockchain, and just like that, the goalposts have shifted. This is what we've all been waiting for; this is what will really bring bitcoin into the mainstream, there has to be something big here when you look at all the colossal mountains of cash that have been dumped into the bitcoinverse... yet somehow, we're still at a loss as to exactly how the "x but with blockchains" formula is meant to revolutionize everything. If the 100 million dollar investment into 21inc's vision of putting a bitcoin miner in every refrigerator is any indication of what we're to expect from all this investor cash, I think we can safely assume that what we're witnessing is simply the hyperbolic bitcoin hype machine functioning within normal parameters.

Of course, I'm probably just an idiot who doesn't "get" bitcoin, it's pretty difficult to understand, since even after all these years I just can't grasp the amazing potential of bitcoin. What other explanation could there be?
If you design the system correctly, flickering should not be visible to the human eye. Obviously that depends on factors like clock rate of your transmission and your coding technique. As long as your signal is reasonably DC balanced and your modulation rate switches faster than the human eye can detect (say > 60Hz), you should be in the clear. The IEEE 802.15.7 working group [0] proposes clock rates of 200 kHz to 120 MHz, which all should be fine.

As for a separate IR emitter/photosensor, in theory it could increase range. Range ends up being decided by a bunch of tradeoffs and channel conditions that effect your Bit Error Rate (BER), which increases the further you move away from the source. The major factors that effect BER is the noise in the room (the ambient irradiance levels of other light sources), your transmission power, photodiode sensitivity to your wavelength, filtering quality, area of photodiode, and forward error correction quality. So moving to a wavelength with less noise certainly would help tremendously, assuming everything else is equal.

I'm not sure what the demographic is that comes to HackerNews, but anytime there is an investment article, I'm always shocked, because people some how become the authority of investing. Yet I don't think many financial people come to the site.

Someone hears that Warren Buffet speak on CNBC, that you should invest in an index strategy. So let it be written, so let be bought. This keeps people warm at night, because Uncle Warren said something that you can understand.

Anybody that is critical of your buy an ETF strategy, is the enemy. But yet you reference a one line strategy and now you are genius! Where was your ETF strategy in 2008? Negative -36% return? How about early 2000? It would still be in the crapper hadn't Uncle Ben started printing money in 2009. But hey, you don't need to understand anything about interest rates, money supply, high frequency trading and or federal reserve, because at the end of the day you saw something on CNBC!

I'm more than happy to encourage buy more of your investment philosophy. Keep buying, buy the dip, buy when it goes up, buy when it goes down. Because the market is up ~250% since 2009 and it can only go up. Economic cycles those are a thing of the past, the market is only going to trend up, no inflation or deflation in sight. It's now clear you know what you doing! Your incredibly intelligent, successful, profitable, secret strategy. Remember not tell anyone, well because they might overcrowd the trade and reduce profitability.

What should be taken from this is when a university has more money than GDP of 2/3rd of the nations in the world (individually ofc) something has really went wrong.

Not saying the educational institutions shouldn't have money but when you have more assets than the GDP of Luxembourg you maybe should stop charging 25K a year...

Errr, to my knowledge, neither of them made major contributions to the Lisp Machine, outside of perhaps ideas.

It sounds like you're referring to their Scheme chip project, which they did not have the resources to push to success, e.g. getting the microcode right in one or two tries (the computing resources to simulate it were not available).

The Lisp Machine proper was a project done with TTL and fathered by Richard Greenblatt, who probably did some hardware design and more likely microcode work, as well as system software as I recall. However the principle hardware designer was Tom Knight, David Moon wrote a lot of microcode (the Lisp Machine's microcode did a lot, e.g. eval, GC, the bytecode interpreter), he and Dan Weinreb are the only authors listed on the cover of the 1981 4th edition of the manual, Weinreb wrote the first text editor for it, the per Wikipedia and my faint memory the 2nd EMACS implementation, and the first with a GUI and done in Lisp. Howard Cannon developed the Flavors OO extension, with which I remember a lot of the GUI was implemented.

It was a pretty big project; hmmm, TempleOS is the only "comprehensive" OS I can think of that was done by one or two people.
Police vehicles seem like one of the last things that should go electric, because they get used around the clock.
Ok, sure:

Making the borrow checker happy with their abstractions...

You've seen iton #rust too, Im sure. People trying to make a genric reusable thread safe Foo and getting stuck with the borrow checker rather than making a specifc solution to a problem that uses unsafe or whatever and actually solves the problem.

I know Ive seen it several times.

Safe good code is better, but it's also a distraction in many problem domains.
I've seen whole data centers still working completely flooded with water. Crazy.

But "we're in a bubble" is seen as savvy while "we're not in a bubble" is seen as naive. Always take the side of pessimism if you want to seem cool and smart.
My real analysis textbook says on the back:

Was plane geometry your favorite math course in high school? Did you like proving theorems? Are you sick of memorizing integrals? If so, real analysis could be your cup of tea. In contrast to calculus and elementary algebra, it involves neither formula manipulation nor applications to other fields of science. None. It is Pure Mathematics, and it is sure to appeal to the budding pure mathematician.
This is analysis paralysis. It's not a mental deficiency, but rather an anti-pattern usually brought on by insecurity and lack of knowledge about which decisions are actually important:

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

The way out of it is just to pick something and see how far it takes you, accepting that you may have to backtrack and redo stuff in the future. There's this myth that experts got that way through good decisions; no, usually experts got that way because they made a lot of bad decisions really quickly and dealt with the consequences, and so now they know not to make them again.
I suggest motivation. This slow cognitive process thing just sounds like an excuse, do the best you can in that moment and forget this story about slow cognitive processes.

Yup - I actually live in the woods near Concord where Thoreau used to wander (Walden pond is round the corner). It's very nice. Good schools. You can get pizza delivered.

People say "Oh, but surely it's changed a lot since Thoreau's day", but honestly - we're talking about Concord. The town was founded in 1635, it was already 200 years old when Thoreau moved into a hut on his buddy Emerson's land. The Boston and Maine rail line past Walden Pond was already running when Thoreau moved in, for goodness' sake.
Freada says she's a researcher, all about the numbers, etc.

If we're going to talk about who is over-represented, I've got to ask: is it early onset senile dementia or the strong contact high in Berkeley, but (and I know this is impolitic) how does she overlook, ahem, the Jews?

I mean, pound for pound, they are the most over-represented group not just in elite SV circles, but every human intellectual endeavor worth writing about. So shouldn't the diversity initiative really be framed as "how do we get more gentiles in tech?"

In that light, and nothing against Sam Altman who is totes awesome, but by what metric is replacing Paul with Sam at YC a move toward greater diversity? Does the tribe get a special dispensation? Do I need a graduate degree in African studies (or per another comment here "intersectional feminism") to grok it?

To be clear, this is perfectly fine with me. But, by analogy to their reasoning, should this disparity be attributed to a shortcoming among gentiles? Something exogenous (bad bagels, loose circumcision sticthes)? Or is it "structural jewism" and jews have more (re)education about their "jewish privilege."

I hope framing the conversation in this facetious way illuminates how utterly imbecilic this social justice boondoggle is. Remember forced busing? I'm sure the Kapors would have been big fans (out in Gross Pointe); remember Kansas City ($2B dollars spent on predominantly black schools over 10 years)? Remember the Meyerhoff foundation (of course not, Mitch will hope you forget his too in ten years time).

But by all means, keep it up. Look what happened with SCA-5 and how fast Sen Lee's head spun when his asian constituency got whiff of his flacid support of a favorite social justice theme.

As far as waiting for white guys at VC and tech firms to die off, do not ask for whom the bell tolls, my dewy-eyed bobos...
I just want to take a moment to hat-tip a legendary dev. I've heard of you at LEAST since MORE for the Mac rocked the sales charts when I was a teen (I also FONDLY miss Macworld Expos, attended a bunch of them!) Thanks for being an awesome nerd!
if you already have a need of concurrency in your project and want to know how to utilise the library there is a documentation section on the linked page

a good starting point would be the man pages

if you want to know where to start on getting info on how or why you would use a library like this check out the articles or slides section, or wiki around unfamiliar words in the man pages
While I agree with raising the minimum wage, you make a really good point.
What's your opinion about bloggers that enjoy getting a bit of ad revenue from their posts?
Equity markets have the DTCC and registered exchanges. Even though there are some 16th century pieces of paper still around today, actual transfer of equity from one party to another is little more than an exchange notifying the DTCC that a transaction took place, and the DTCC changing a log in its own database moving the stock from one clearing firm to the other. That sounds boatloads more efficient that blockchain already.

There are other security markets that do not operate as efficiently, but to me, the solution looks more similar to the DTCC model, not the blockchain model.

Keep in mind, too, we still do not have any system that reasonably ties bitcoin technology back to a real-life asset. Bitcoin works because it's self-contained. In the world you described, I could have all the necessary ones and zeros to represent an ownership stake in a Nigerian oil company, but that means diddly squat if it's impossible for me to exert control on the company or receive dividends. Nigeria nationalizing the rigs has nothing to do with whether or not I have a claim on it with a piece of paper from an exchange or a cryptographic key. Those are currently real-world issues impairing investment in those regions, not the exchanging mechanisms. Though I do concede, the exchanging mechanisms aren't perfect.
I disagree.

Without a Rosetta stone for dolphin language, we need a huge data set to distinguish how their language translates into ours and vice versa. This would be impossible to do without the technology we have now and this technology we have now would be impossible to create if we had no arms/materials to build things with.
I guess you could upgrade to the 5S.

README.ru has the real documentation- google translate does a pretty good job with it. It mentions that the algorithms are from the Dragon book.

I didn't try the code, but I think it's missing full Unicode character class support (for example when you use \w). But I see it handles Russian :-)

Carnatic music is the original R&B.
I think another question to ask yourself is, why do you feel this isn't normal?

If others claim they could do the task faster, consider that programmers chronically underestimate.

If you've seen others do it faster, it's possible that they are taking shortcuts, making quicker decisions that will involve more work later. From your example, you've carefully picked a library and thought through how to integrate it properly into your code - these steps can be skipped for speed, but the cost usually isn't worth it.

There are always going to be better programmers, but they're often not the ones who claim to be great, or fast, or rockstars. So I'd just check to make sure you're not making unfair comparisons of yourself.
Same here, but will next year be any better?
I agree. I recently had to do some java work and had to come up to speed with Springs dependency injection. When it worked it was fine, but when something went wrong there were so many layers of abstraction and vague error messages it was a nightmare to try and solve problems.

I don't see what is wrong with the 'boring' way of dependency injection. If a class relies on another class, pass it in the constructor explicitly. It's simple and easy to follow the stack back to find problems.
Of course gold has value due to its usefulness. Plenty of electrical equipment is gold-plated. Dentists fill teeth with gold. It has other industrial uses as well.

The value of precious metals are solely due to their usefulness, extending usefulness to their aesthetic, decorative quality as well. The price reflects this over the medium and long term. Of course, an ounce of silver in 1979 and 1981 was $8 an ounce, but for a variety of reasons it hit $40 an ounce for a few days in 1980. Short term price swings happen due to events, or major technological breakthroughs, but over time, price reflects value and utility.

> Can you explain to me why dollars have value? Euros? Drachmas?

Until 1971, dollars (and other currencies) were explicitly exchangeable for gold. Today they're implicitly backed by gold (or whatever commodity the US government can drum up).

Can you explain why the USA holds thousands of tons of gold in Fort Knox and other places? What is the purpose of the expenditures to hold all of that gold? There is only one answer - to put a floor under the value of the dollar.

Bitcoin does not have thousands of tons of gold propping up its market cap.
It would certainly be easier, but on the time scales we are talking about (full brain digitization and reproduction in a digital space vs body regeneration) I imagine the orders of magnitude of time for both are much closer to one another than they are to the present day. If you got to one, you would probably last in the freezer until the other, and you can certainly request to only be revived through methods that repair the preserved brain rather than copying the information it contains.

PS: Hi WalterBright, D is amazing :<
Well, since they're practically wiped out and we're not, I'm not too worried.
Why we need data on what the poorest think
On the other hand, false positives are a problem with more advanced techniques that ignore things like variable names, especially if assignments are narrow in scope (as course assignments mostly are) and have exacting requirements.

For example, there aren't very many sane ways to write a Hello World program.
What I wonder is whether it's necessary to teach it the wrong way before we teach it the right way. Neither answer to that question would surprise me.

As an example, I remember that as a high school maths student I had real trouble believing that 0.9 repeater equals one.

Nowadays, post university, it seems trivially true.
I just started using Input, giving Anonymous Pro a little hiatus. It has been pleasant on the eyes.
Google has a similar library with similar goals. See https://github.com/google/re2/wiki/CplusplusAPI It also removes backtracking.

The idea is that backtracking may kill performance, so a specially crafted text that causes a lot of backtracking can be used as a DoS attack.
Well, if I designed a language that was C++ but stripped of some specific features for a purpose that made it less than C++, but still not quite just C, I might call it C++-- as a joke. In that respect, I think it makes perfect sense.
You need to dig up every street every winter for repairs anyway, and you need the inductive loops for adapted traffic lights anyway.

Effectively, you need the infrastructure, most cities on the world have it in some way – either as inductive loops, or by using RFID toll systems, or similar.

So, you have it already, and you can get the same data out of it without the cost of breaking everyone's privacy.
It is not widely accepted by dolphins that humans have language. :-P
See https://swtch.com/%7Ersc/regexp/regexp1.html for a fine explanation of DFA vs NFA.
Again, that's leaves it as a subset of Perls regular-expressions, not a disjoint/distinct set, which is what incompatibility would imply.
https://swtch.com/~rsc/regexp/regexp1.html and the articles it links to are a good detailed explanation of the advantages of the DFA approach.
See also https://swtch.com/%7Ersc/regexp/
Scary to think that a major search engine really uses regular expressions heavily. Regexprs are great for quick scripts, but one would expect that in major production applications better and higher level parsing algorithms would be used. It must be a nightmare to debug if you have a lot of reg-exprs interacting in a large code base.
It would've been refreshing if she hadn't tried to make it into a large, drawn-out essay and had just said "been there, done that, got bitten by mosquitoes, saw a moose one time, that was cool" rather than opening with an attention-grabbing anecdote of an eagle attack that turned out to be 3 grumpy owls, going off on tangents about running through the wilderness to get away from an ex boyfriend, her spiritual connection with the breeze at the end of her stay when the world seemed to be "alive with so much dance."

It also wouldn't have been that interesting, to me at least.
> The difference between a well rested brain and a sleep deprived one is night and day.

When I don't get 8-9 hours of sleep, I code exactly the way OP described. Things that normally take an hour, take a full day because I can't focus and miss the most embarrassing, basic stuff.
How is it any different at all from sleeping and waking up? How do you determine, each morning, that you're still you, for whatever value of that line you choose?

Even more starkly: ever had surgery? Ever taken benzos? Or been black out drunk? I could give you an amnesic med, like midazolam (often used in surgery) then tell you that you were absolutely certain to die. And I'd be right (again for whatever flimsy values we're using here). The version of you that is hearing me tell you these things will disappear from earth. You'll wake up in the morning, none the wiser.

Edit: Only scary part is staying conscious after the cutover. Greg Egan gets into some of this with excellent short stories in Axiomatic (The Jewel) and Luminous (Transition Dreams). But that's still not really much worse than benzos.
Let me just quote http://rationalwiki.org/wiki/Globalresearch.ca
"While many of Globalresearch's articles discuss legitimate humanitarian or environmental concerns, the site has a strong undercurrent of reality warping throughout its pages, especially in relation to taking its news from sources such as Russia Today RT[2] and Press TV.[3] Its view of science, the economy and geopolitics seems to be broadly conspiracist.
Whenever someone makes a remarkable claim and cites Globalresearch, they are almost certainly wrong."
As someone who is still, 17 years later, running a large-ish production CF site on a daily basis, and still teaching new hires and interns to use CF every summer, I'm happy to see a little (!) CF love on HN.

I've built production apps in Rails, PHP, and CF, and I've tinkered with Go, Python, etc. I still haven't found a language that gets interns from "don't know HTML" to "working dynamic web thing" faster than ColdFusion.
The way this works for me is that ideas in and of themselves are easy: you have a mental image of how it works (a web page!) and maybe articulated a few sentences about how the parts fit together. The thing is, implementation is much more complicated and tedious than this. "Oh, a site with users, posts, likes, tags, and search." Then you start getting into it and parts start taking you a week and then your brain starts tumbling over itself, conflicted between how easy the idea is to explain and how involved the production of it is.

Let's go to the redoubtable Yegge and his concept of "Shit's Easy Syndrome":
