Is that even possible? It's not as if we're swimming in demand for unskilled labor at a living wage.

The underlying problem seems to be that college (along with housing and healthcare) are too expensive and people can't afford them.
Runtime performance will obviously vary across platforms, but in all cases, at least the executable will be much, much smaller! :)
Uh, no. Enron’s debits and credits always added up. It was what they claimed as credits that was the problem.

From reading the OpenBazaar blog (I searched for a whitepaper first), it seems like they aren’t trustless - they seem to have a concept of a moderator [0] who you need to trust (Sounds a lot like Eve)? I’m really not sure how this is technically possible, especially when dealing with physical goods.

This article is suggesting that higher than normal number of people who are on Autism spectrum explains the gender imbalance in tech industry. Further it is somehow attributing this to Damore's reasoning about his memo. There are a lot more normal people in the industry though - surely all the woes directed towards tech industry are not due to folks on the spectrum?

Having worked with normal devs and "brogrammers", I have a hard time accepting that the "brogrammer" that is constantly belittling others on the team, second guessing other's work output is on the Autism spectrum. Wouldn't someone on the Autism spectrum not want to draw everyone's attention towards themselves and just do their own work?

I had a friend in grade school who was on the Autism spectrum. From what I remember, he was awkward, self-aware, genius, not looking for attention - but he was never a jerk and if he knew he was making someone uncomfortable he would stop. To suggest that people on Autism spectrum are misunderstood as brogrammers is a stretch.
You got it right. It’s no good for that.

No crypto system can close trust beyond the network and it’s nodes. Some other dependency is required for that. Crypto might be shown to allow for some new kinds of dependency to step in at that point but I don’t know of anything like that myself.
> If nothing is done, the number of Americans with health insurance is expected to decline by millions this year (due to the repeal of the health care tax (I forget the term they used) in the new tax law).

This is a bad metric. We should be worried about healthcare costs, not insurance coverage. You can have "universal coverage" and still be wrong, because people are paying $5000+/year in insurance premiums they can't afford.

If it didn't cost a hundred thousand dollars to get sick then it wouldn't be a problem for people to not be insured against it.
The description on the YouTube page says the original footage came from a Japanese high definition demo (probably a HiVison MUSE system). HiVision MUSE has development going back to 1979 according to Wikipedia [1].

Why can't you reach someone those things in JS? JS has all of what you mention...
It seems absurd to recommend a teaching language without any consideration for the technical merits of the language to me. The argument in the article is among the lines of lets use javascript because it has the most shiny things.
You could reach for mysterious counterintuitive induced-demand effects in the housing market. Or you could observe that creating six-figure jobs, recruiting people from around the world, and paying them relocation expenses to come to your city, absolutely does "induce" demand for housing beyond any shadow of doubt 100% of the time.

If Bay Area governments were as NIMBY about desks as they were about beds, we might not be in this mess. Now that we've built the desks, we need the beds to go with them. (Or burn down the desks? The sheer comedic value of a government on an explicit job-destroying program might be worth it).
I'm not sure I follow your point here. Are you adding to what I said or do you disagree in some way?
Thanks for your feedback
Additionally, it is governed by the structures of code. Technical tools like programs operate in very precise deterministic fashions which do not map cleanly to the world of human contracts and other agreements. So it’s sort of a tough problem to have automatically executing programs that can be exploited by people who have a more sufficiently sophisticated technical understanding of a “smart contract” where there is no superior entity to resolve disputes of understanding.
I’ve seen some pretty useful models for delegation of authorization come up. For example, a contract deploys trust to a root node in the chain (somewhere in the chain), then the chain allows public distributed rules regarding that trust encoded in the contract via transaction. Effectively, the holder of the trust “pays” the currency of privileges to the receiver. The advantage here is the ability to transmit privileges is entirely autonomous.
I was wondering today if it would enable new and exciting forms of MLM (Amway, Nutrisystem, P90X, etc.) as the downline can be encoded directly.
Well, I can offer an example. This is a test of an LED using a bench power supply. In this test, efficiency drops every time current is increased, without fail.

Objective is often in the eye of the beholder. I do express opinion, but I try to back them up with evidence.

The Fiber Scanning Display is in a whole different category. This looks like pure lying on Magic Leap's part.

In this particular case I have tried to lay out the math that proves that Fiber Scanning Displays are never going to support high resolution. No amount of money or time is going to make Fiber Scanning Displays work. I picked this case because the math was simple to follow and easy to prove that it was not possible. Yet it has been a key point in Magic Leaps Presentations and patent applications through to the latest ones printed.

I think it is a very valid point to asked how a company could have been presenting something that was not possible, why people invested in a company saying things that were not possible, and why Magic Leap is holding to the fiction that it might be possible.

It seems to me to be a pretty simple question. Were they lying or did they not know what they are doing?

There are other areas of optics and image quality where you can argue about whether the image quality will be "good enough" but Fiber Scanning Displays is a black and white issue.
Also worth checking out, not sure if its a recent algorithm or just now in vogue, but wave function collapse. See https://twitter.com/ExUtumno?lang=en for some good examples.
We do have a lot of relatively unskilled jobs that claim to require 4 year degrees, though.

Is college too expensive or is it over-required, or both? Even if it was free, that's a pretty substantial 4 year opportunity cost.

The other part, a drop in international students is something different, though. To conclude how damaging that is, we'd need to know how much of the cohort that dropped off would've otherwise stayed in the country, etc.
Show HN: Cronicle, backup archives rotation triggered by cron
No. I support the blockchain and think it will be revolutionary. However, Enron's issues weren't attributable to some discrepancy between credits and debits.

Accounting, surprisingly to folks who've never studied it and think it's simple arithmetic, requires judgment, based on rules that are sometimes grey and subjective. When you add in legal complexities, it becomes... well, more complex and therefore open to manipulation.

For instance, Enron was able to hide many liabilities by marking it (in hindsight) below market, since... there was no market for said liabilities. So it was impossible to value them. Furthermore, it hid other debt in obscure subsidiaries that were only tangentially, legally and fiscally speaking, connected to Enron.

The blockchain confirms, with better accuracy than existing systems, "X transaction occurred between Y and Z partners." It does not confirm "X's assets were appropriately valued and marked as such to a non-existent market, and X is most definitely a legal subsidiary and is overseen by the fiduciary duty of A Holdings, Corp."

The blockchain has the potential to be a far more efficient settlement system. But saying it prevents Enron or Madoff is simply not true at all.
The Chinese property bubble makes the USA property bubble look tame in comparison. At least rents are cheap ($1000/month rent is about $1 million to buy). Density doesn’t fix anything if many apartments are speculative investments and not worth the effort of renting out (because rents are low anyways compared to the appreciation).
Hey, you can do that reversal with a registry edit too eh: http://www.vvse.com/blog/blog/2012/02/27/reverse-scrolling-o...
The idea behind cronicle is that because doing backups via cron is so common (like triggering a pg_dump), why not add a line to your cronfile to take care of the backups rotation once your dump is done ?

cronicle takes care of organizing the data in daily/weekly/etc directories, and deduplication too : all organization is done using symlinks, underlying dumps are deleted when no more symlinks point to it.

Scratched my own itch, but interested to know if it brings something new or if existing tools use same approach.
BSD man pages (and many Linux man pages, though a minority) are written in semantic “mdoc” macros, rather than the classic “man” macros that are strictly presentational.

If you’re using mandoc (http://mandoc.bsd.lv/) as your man(1) program—the default on OpenBSD and a couple of Linuxes like Void and Alpine—it will use these semantics to generate hyperlinks in the terminal using more(1) and less(1)’s ctags support.

So on my machine, your example becomes:

type man foo
type :t
type p

This brings me to the first instance of a command‐line flag named “-p” or environment variable named “p” in an itemized list.

It translates to HTML too—check out the links generated by the web viewer, which uses the same backend. https://man.openbsd.org/ls.1
Blockchain’s potential goes far beyond currency and investing. At it’s core it’s a way to protect and validate information in a decentralized way. That can be used for ANY information.

In theory a blockchain could serve as the source of truth for birth records, health records, property records, favorite cat videos, etc... The possibilities are endless
Just wrote my first Python program today, to massage some text files. It was super easy.

I also found the syntax, uh, interesting. Mainly the lack of braces to denote blocks, ie functions, loops, if statements, etc. Indentng to me seems problematic and a learning hurdle. But as a long time Pascal/C/Objective C/Swift/JavaScript developer, what a virgin programmer thinks I’ve long since forgot.

Better than that garbage JavaScript though.
There is just so much magic involved

Compared to JavaScript, where {}!={} and [["2"]]==2?
> Oh look, another "middlebrow dismissal" (https://news.ycombinator.com/item?id=4693920) upvoted to the top of a HN post. Color me surprised.

Do you see the irony in using a low-effort, middlebrow dismissal to call another comment a middlebrow dismissal? Re-read the comment you cited in your criticism, I think you may have taken the wrong lesson from it.

Unlike pg's comment, yours does not advance a substantive criticism or draw a novel insight into the conversation, which means it's also the same type of dismissal he was talking about.
virtualenv makes it trivial. It's not like it's strictly enterprise-grade tech.
It's not the only the correctness of the debits and credits that is possible, but also determining their nature. Of course these implementations would have to be molded to fit for each use case. The technology is nascent.
Interesting that the prime pages link is dead, and they didn't include the prime number on their own site.

I want to give a little context to why am asking this question...

Recently I've been seeing a number of really smart people and established companies claiming blockchain is going to be ubiquitous and revolutionise a large number of different industries. However, outside the case of cryptocurrencies I'm not sure what applications the blockchain has or why myself as a developer would want to start using this revolutionary technology.

I understand why in the example of cryptocurrency the blockchain is used. However why companies like Facebook or Microsoft would want to use blockchains for things is beyond me. It also confuses me why if the blockchain is as revolutionary as people say that it's only just started to get attention. Bitcoin has been around for quite a while, and has been well known in tech circles for a long time now.

If my comments here seem critical it's not because I have any opposition to using the blockchain, but simply that I'm confused and desperately trying to understand what I'm missing here. I genuinely don't understand why or how this technology is going to become ubiquitous or revolutionise much of anything - which concerns me given the track record of some of its advocates.
I'd suggest that there's an element of the the canary in the coalmine to this metric. As another commenter noted, it is much harder to fudge deaths vs employment. Hence greater believability and therefore triggers the question "why" in the broader populace.
I’m not saying we have a lot of space in cities, I’m saying we have a lot of space between them. Milpitas should be a suburbs.

China is spending trillions on infrastructure and trains and we whine about 6b for a huge train station in the center of a hundred year old city, while we give $1.5 trillion tax cuts to corporations
The lack of types is just one thing that disqualifies JavaScript from teaching serious computer science concepts.
There are a whole lot of people who think that the web is the future of computers and that everything is going to run in your browser and everything on the internet is going to use the web.

Those people are _new to the game_, they don't understand the technology, or how it evolved, and they most definitely have no f'ing clue where it's going.

I laughed when he said Javascript, because I thought it was a joke. I can see what he means tho, at least in the limited context of this topic "For beginners", it's a fine way to teach basic programming concepts. But if you aren't building a website, you should not be writing in web languages.

You know what's a good teaching language for beginners? Anything they can actually use 5 or 10 years later so they haven't wasted months of their lives learning something with an incredibly limited practical scope.

Languages are not lessons. Hello World is a lesson, and it works in any language.
I don't understand why Nintendo has shut it down in the first place, in spite of its popularity. These community features can enhance user experience, especially when implemented right in the game. Why wouldn't they even continue Miiverse on later consoles like the Switch?
Using the terminology of your link, tptacek is not "slightly more than unsophisticated" wrt security.

Dismissive, sure, but "middlebrow" it is not. I like that term, and I don't want it to turn into a generic, meaningless slap like "fascist" or something.

And it's worth taking seriously any comment about security on HN when we're lucky enough to get one by an expert, whether it's tptacek, moxie, cperciva, the professor who goes by his initials (whose name escapes me atm), and probably others.

I'll be more inclined to listen to diatribes about the inevitability of America's economic decline when we no longer have the highest corporate tax rates in the world.

Until then, I firmly place the blame of America's economic woes on one political party. Hint: it's the party of higher taxes.
Yea, the hard part is when it comes to determining the value of the collateral for some obscure project in rural Africa, vouched for by the trader who sold the trade and signed for by somebody 10,000 miles away who might be the traders pal.
This is a horrible review. First he claims his competitors are whores (his words, not mine) but then doesn't back up his review with any actual information. Just look at this review of the navigation system:

"Navigation/GPS: Wonderful. In conjunction with Tesla's excellent voice control, it's a revelation. Other manufacturers should weep."

That's it. That's the whole review. It doesn't tell us anything about why it's a revelation or why other manufacturers should weep.

There's lots of different potential approaches and contexts for teaching beginners.

For low-contact teaching where the students were going to be doing lots of independent work between contacts, that was more concerned with enabling students to try stuff out, I'd generally agree with this.

For other contexts, maybe not; I think Python (or Scheme, or some others) a better choice for a first language in a broad, structured CS curriculum. Though I'd certainly still agree JS is a useful thing to have in your toolkit fairly early on in programming these days.
> If it didn't cost a hundred thousand dollars to get sick then it wouldn't be a problem for people to not be insured against it.

This is a dicey one. One of the things that drives treatment costs up is more advanced technology. Should we go back to 70s/80s-era cancer treatments, HIV treatments, surgical outcomes?

We need a lot more national discussion about where the real opportunities to save money are, and what should and shouldn't be covered, and if there's a one-size-fits-all solution or not, because some of the costs will continue to trend upwards as we become more able to keep more people alive for longer (otherwise a good thing!). Some [surgeries, drugs, treatments] cost tens of thousands of dollars and save lives. Some cost tens of thousands of dollars with dubious outcomes. That's where the meat is.

But we have no hope whatsoever of getting there if we can't even agree that mandated health insurance at at least some minimum level is necessary policy. Insurance needs that much to be able to work at all. Or give me the reverse: if you opt out of health insurance when you're healthy, saying the sick can fend for themselves, then you don't ever get to opt back in. (That's not gonna happen, obviously.)

What ideally should be happening is that existing tools get incrementally upgraded to fix issues and add improvements rather than scrapped and replaced as if they're disposable.
I think you are a little optimistic about blockchains preventing Enron type situations. From wikipedia their issues were:

>by the use of accounting loopholes, special purpose entities, and poor financial reporting – were able to hide billions of dollars in debt from failed deals and projects.

which you could probably spot if you had access to all their bank accounts including those of the special purpose entities but no large company is going to make all that stuff public. If it's on a blockchain it'll be encrypted some how. The people who are supposed to have access to that stuff and check it are the auditors, in this case Arthur Andersen who screwed up and were destroyed by it going from 85,000 employees to mostly closed.
> that can output 10K LUX

What does this mean? I would assume the surface brightness of the emitters is a good bit higher than that. Aside from surface brightness, lux does not provide any information about a light source without a distance. The SI unit of luminous flux is the lumen, and luminous intensity, the candela.

I have a Viltrox panel with similar characteristics, but smaller (adjustable color temperature, CRI 95+) and I think it uses 5mm Yujis. Brightness adjustment is non-PWM. It's also meant to take a camera battery, but I converted it to use two loose 18650s. Model VL162T, $30ish on Amazon.
It won't prevent corruption. It will alter the logistics of corruption though.
It's not bad, but man the way the author throws around multivariate (e.g. non-curried) functions all over the place is sooo confusing. I remember reading a λ-calculus book that would do that and it's really not fun to try and parse (see the bottom of pg. 7).

But I will say it's very cool to see how HoTT derives all the basic tools you'd use in propositional calculus (A: A -> A, :(A -> (B -> C)) -> ((A->B) -> (A->C)), and so on).

Huh? America can be economically ascendant - we have a LOT of businesses doing quite well with massive profits and cash holdings, tax rates completely aside - without being dominant in every single industry. Regional drug addiction trends are NOT national economic issues (the national economy has been going up at the same time as the opiod abuse!), but plainly regional ones.

What specific parts of the opiod issue do you think a lower corporate tax rate will fix?
