But that‘s exactly the point behind the footnotes remark that you seem to dislike.

Plato owned philosophy so completely that everyone, even centuries later, still referenced him.

You coming across ideas first via some more recent source does not invalidate him any more than Wordpress invalidates the importance of Movable Type.
> Yes, trains already exist and have existed much longer, and yet have obviously lost out to the truck.

That may be in large part due to the substantial government subsidation of car/truck traffic through public roads, not the merits of one against the other.
Hi, excuse the delay.

I was saying that blockchain might help address fraud, against untruth or deceit. For example I believe that yes, the American Indians would have been better off with unalterable titles to their lands. Would it have changed history? I don't know, but in other situations it might, and for that I point you to Hernando de Soto Polar's site. https://desoto.com

I was also saying that the claim that "nobody cares about the 'truth'" (and so blockchain is not useful) is misplaced, and that in this case there's no good point for using the word truth in quotes as if it were something illusory. There are times when quotes around the word truth make sense, like in philosophy, but this is not one of them. An exception is if you are talking about the potential to use the blockchain to make lies permanent.

And third I was responding to your statement that people who support the blockchain are often hoping to be freed "from the constraints of governments and society", and that my comment was a good example of this. Your comment might be correct about others, but I'm not a libertarian or anarchist. Rather, I'm a bit worried that technology like machine learning and even just social media have the potential to weaken and even destroy our democracies by using lies (doctored video, for example) as political tools.

But you don't even need machine learning and social media. In Russia, lies have undermined what began as democracy under Yeltsin to such a degree that it is now for all intents and purposes a dictatorship. In Russia the playbook is basically as follows: an event occurs that makes the Kremlin look bad. The Kremlin uses its media outlets to make up alternative truths (lies), several versions, some more implausible than others. The person seeking the truth, what actually happened, is now looking into a hall of mirrors. Not being able to see anything clearly and having to spend their energy disproving several false versions, no meaningful discourse happens. The event, in this way, has been neutralized by lies.
If a blockchain can help with this kind of problem, then I'm interested.

Edit: Btw, I'm not like a cryptocurrency enthusiast, don't program Ethereum contracts, own no BTC or any other crypto, and believe and have argued here at HN that BTC is a bad currency because of volatility with makes credit and debt impossible. Additionally BTC is used for crime and as a way to cash in on fraud, malware, threats and so on, and I'm not interested in any of that.

Ask HN: How to decline a demanding interview coding test?
As part of my job application to a start-up company, I received a coding challenge which is more like a complete project and not clearly defined (and cannot be done in 2-4 hours!). You need to research the strategy and important factors for the problem, find and download public data, use that data to develop models, and make predictions and conclusions based on the model and strategize for 20 years ahead! Technically, I do not have problem to dive into the project but to make something reasonable out of it, it takes time.

I do not know whether it is worth it to put that much of time on a single job application, and frankly seeing the way the company tried to test my skills, I am a bit disappointed about the job itself.

I have not applied to a ton of jobs, the ones that I applied to required a standard coding test (like Codility) or a well-defined challenge with a 2-4 hours period.

First, I want to know whether this kind of tests are usual in job interviews (and if I should be prepared for that)?

Second, how to politely decline the coding test (or any other way that may not end in losing the job opportunity altogether)?
The precedent this sets is interesting. From my interpretation, a business must request reviews from all customers, via all methods, for each platform, in order to not be considered ‘manipulating consumers’.

This will have impacts for all the saas review management products, as their key selling point is usually: get more reviews from your happy customers, or stop your unhappy customers posting reviews. Which is usually done by targeting or omitting either group.

Any Australian business using such product would now be on the hook.
+1. It was a terrific read when I took my Computability course, very, very well-written.
What a beautiful story of devotion! Imagine someone going to this much trouble over your work, it's quite impressive.

I used to worry about this kind of thing, using cdparanoia and so forth on Linux to manage my music. When I went Apple I eventually went iTunes, which is a mixed blessing. I feel like it has made me able to appreciate more music more easily by lowering the cost barrier, but it has reduced the amount I appreciate an album substantially. And it's hugely inconvenient when they disable my account for strange reasons or my internet connection vanishes. So I may return to manual management someday.

Are you trying to make people make fun of us?
Yes, it doesn't at all seem right.

After I learnt Haskell, I was forever wishing the languages I work in professionally had monads. But they're all strict languages. Monads give us a nice consistent way of working with stuff inside generic wrapper types (e.g. nullable, arrays, classes and other partially applied functions, state machines, data paired with a world, partial functions converted into (more) total functions by tagging success and failed operations). My professional languages have different solutions for all of them and so it's harder to separate the rules and the mechanisms with heavy syntax

It's more that it's very convenient to think of side effecting functions operating on a world and returning a new one once you already have this powerful abstraction.

I like the fact that the type system encodes that the function has a side effect. But I don't particularly care that the language is lazy when I enjoy this benefit. They're quite independent.
Does not seem usual to me.

It’s ultimately up to you whether you think it’s worth the time.

How much previous experience do you have in the field?
Don't be too jealous. My main concern with Node and its ecosystem is maturity and security. It loses hands down on both those points compared Ruby / Rails especially in the area of dependencies.

This keeps me happily in Rubyland.

Yes: you can use Audacity (https://www.audacityteam.org/) to "diff" two waveforms by subtracting one from the other.

For comparing .wav files you can also treat them as plain binary data, and use standard diff tools. For example I used `cmp -l` to count differences between rips, and `vbindiff` to view them.
First thought: Invert the phase of one of the tracks 180 degress, then sum them together. Anywhere the is a bump in the waveform would show a difference between the two sources.
This is very similar to the technique used by https://en.wikipedia.org/wiki/SpinRite

This didn’t seem to be an issue of wear or damage – the CD itself was probably defective from the factory.

It would be very interesting to look at the surface of the disc under a microscope, to see if you can find the defective area --- knowing which track it's in, you can determine the approximate diameter at which it occurs, and then rotate around that diameter looking for abnormalities. The pits and lands are invisible to the naked eye but easily viewable with a light microscope:

https://en.wikipedia.org/wiki/File:CD_Pits_at_6.25x_Magnific...

At 1200 bits/mm linear density of a CD, the 5KB (40Kbit) defective section will correspond to ~33mm of track --- probably quite obvious if it is a physical defect. (A "logical" defect, where the bits are OK but the ECC is wrong, will not be apparent at the physical level.)
Simple hack to this problem is forget about buying stuff online.. go to the store and get it right away.

The Internet can not believed for much and is easily manipulated for the better of those smart or immoral enough (however you view it) to use it to line their pockets.

first they had fake reviews. Amazobn required actual purchases so companies would pay people to purchase and return. you can't ban returns otherwise there would be no negative reviews.

how can this be solved? some kind of reputation system? how would you lose rep?

I love to hear your ideas?
If you mean the money the Fed printed as part of QE, no, it went into the banks' reserve balances at the Fed, where it has been ever since.
From the article:

Facebook spent years building out News Feed advertising — not simply the display and targeting technology but also the entire back-end apparatus for advertisers, connections with non-Facebook data sources and points-of-sale, relationships with ad buyers, etc. — and then simply plugged Instagram into that infrastructure.

Then in the article this argument leads to a conclusion that the fb pre-work saved years of monetisation effort for Instagram. Is it not the case, though, that it took years for the first player but would take much less for the followers as they already know what a solid way to do it looks like and they have consumers who are conditioned to this way? Other than the relationships with ad-buyers, everything else on the list is not easy as in a day's work but would take much less time for someone to rebuild using the established paradigm.
And for avoidance of aircraft: except for some last-second emergency reaction, this is the opposite of automated. We have specially trained, highly competent people on very short shifts under pretty much ideal working conditions ensuring that.

To elaborate on your point, its not just chasing pointers, it’s that those pointers point into random heap locations, each of which needs to be allocated individually and garbage collected. Also, because of the haphazard locations of these objects in the heap, you have way more cache misses than you would with value types.
> My point is that the evolved complexity of a human hand is too complex for the general purpose manipulation task.

Maybe if you're constraining 'general purpose manipulation' to mean 'rearranging blocks'. That complexity (and especially the extra brain power to run it) costs energy. If it wasn't useful, we wouldn't have it.

The serverless capabilities is the big plus IMO. You pay for query. If you go with a typical OLAP system like redshift you need a cluster with a minimum number of machines I believe.

I think it compares more with something like BigQuery but if you already have your data in S3 maybe you get a more well integrated system if you stick with AWS tools.

I can't edit this now, but I'd be pretty interested in the reasoning behind the downvotes.

It's fine to be cynical about the CIA of course, but is it just that people don't like the CIA and so they downvote people pointing out actual completely sourced facts which make the CIA look just slightly less terrible?

Because I think the inability to reconcile history with what people's views are is a pretty interesting thing.
> The Fed orchestrated the greatest ordinary person bailout the world has ever seen: it reinflated the US housing market and salvaged the net worth of the entire middle class in the process.

How the the Fed do this? Certainly not by QE, which did none of these things.

> Just look at the cost of a house in 2012 vs 2018

What did the Fed do during this time? Most of the money printed by QE happened from 2009-2013, and QE was shut down completely in October 2014.

Collecting and Analysing Data at Human Scale with Ona and Canopy (Interview)
Having worked in London I appreciate this article being on the BBC. At least in the company I was employed people tended to be late to meetings as standard (10-30min) with the usual tube/traffic excuse....every week as thought this caught them by surprise each time.

It became a problem with meeting rooms being booked but empty so you would use and then get kicked out 20min past the booked time as the people turned up. The company eventually brought a rule if you were not in a room within 15min of the booking start time you lost it to avoid this problem.

I think some people in this enviroment would play to it as 'I'm so busy & important' but I always felt it was such a economic cost to the company having a bunch of people sitting there making small talk while someone was delayed.
Dont be so cynical. I took the comment as serious and agree.
They were off on size/weight, but they guessed the capacity just about right (IBM 0681). I don't think extrapolating out pre-existing trends, for sophisticated people, be "mind blowing." Would your mind be "blown" if you learned that by 2048 you'd have a 100 petabyte drive using, say, magneto-resistive memory (or something else based on anticipated, if not fully developed physics)? Seems like hyperbole (and setting a low bar for peoples' imagination).

Reading stuff written in the 1960s about what today would be like, what strikes me is that technology is so incredibly not mind blowing compared to what we had back then. Even in the area of computers. Hell, we haven't even come up with an input device that beats keyboards, which were invented in the 19th century (electro-mechanical keyboards, not typewriters).
The article states they have found numerous cases of workers injuring themselves at Amazon warehouses. Let’s hear that number. What percentage of warehouse employees is it? How does it compare to Walmart? Why is everything written these days so stupid?

If anything, this an argument for single payer. Your health care should not depend on your job.

This is completely untrue. I have in the past and continue to create web components that "hard CS" folks would scoff at and also quietly use in their own projects if my work weren't owned by my employers.

I've built chunking hi-def megapixel web camera services a decade ago when browsers were limited to 20mb uploads. I've suggested building simple structured data protocols based on xml for a high-rate foreign exchange brokerage client-server architectures. We wanted to secure traffic between the client and server so I suggested self-signed certificates.

I'm not stupid but I'm not a "10x developer" either. I work as a software developer because it's the most lucrative, accessible and interesting opportunity for a non-credentialed individual like myself. I've met folks with Masters in CS that unfortunately didn't merit a basic certificate in the same.
I don't have the equipment for this, but it might not be needed. The disc has writing that goes "through" the top cover, such that you can read the text by holding the disc up to a normal lightbulb.

The text is across the entire diameter and I don't know why it would cause problems for only this track. Possibly the shape of the text?

"This sort of thing is common when buying used CDs, especially if they need to transit a USPS international shipping center. "

As a used CD seller who often ships internationally with no complaints, I am interested in learning more about what is behind this statement.
yes. It uses schema-on-read so it doesn't support indices as far as I know. And yeah, it scans through the data using the schema you define previously
In astro-photography, this is quite common. You take a series of normal images. You then cover the the lens, and take the exact same exposure. After a series of processing, the noise pattern from the dark frames is subtracted from the normal images. It works quite well.
I think to do this right (safely) we need to start looking at how to integrate roads with self driving cars and trucks and at vehicle to vehicle communication.

At some point there needs to be standards set for these kinds of things and, really, the sooner the better.

I think we, as consumers, would be better served with a vehicle that could safely drive down the highway for long distances right now than a car that can drive us to work and back on city streets 10 years from now.

And if we integrate roadway to vehicle communication from the highways outward the transition will be more efficient, especially for trucks.

The CUE data in TLMC is a real bummer. I don't know if it's my music player, Clementine, but a good portion of the tracks I listened to in TLMC didn't advance correctly and instead just kept playing with the metadata of the first song in the album that I listen to. At this point I've mostly just given up on it... It took me 3 months to download it too, haha (curse you, Comcast 1TB monthly data limit!)
I tried that addon, and it is not the same thing. Panorama was an overlay, but this opens a new tab to view your groups. This doesn't really work when you have hundreds of tabs. I'm pretty sure that the old Panorama view is not possible with webextensions, although I haven't really looked into it.
Yes for speed purposes. And yes some people may not like types, that's why I said completely optional. Anyways the optimizer tries to figure out the types on it's own, so give it a non blank slate to start with. You are correct in noting that js is already fast enough, but the problem is the sort of performance gotchas(order of keys in objects) as mentioned in the post aren't really obvious during development time. Types may help level the unpredictability.

Quite slow compared to what?

PHP was popular when it had MySQL bindings that were always up to date with MySQL changes and apache PHP setup was simplistic. Thus the LAMP stack, right? It has always been rather fast, in the larger ecosystem of web scripting languages (especially if you avoided particular BIFs) but it got a LOT faster in 7 as the slowest bits were optimized alongside everything else.

Maybe ZUN himself is cool with people distributing his work on the internet, but I don’t think that all the doujin circles are cool with people distributing theirs.
I don't think that's a charitable reading of the article. The author is not saying that you can't have this knowledge without a degree, he's saying that few people in the field today have this knowledge, because they don't have the degree. The two assertions are different: there are things a degree teaches you; if you have the degree, you probably know them. While you can't judge whether any given individual has the same knowledge without the degree, you can:

1) Expect that 1,000 people with the degree will mostly have that knowledge;

2) That 1,000 people without the degree will mostly not have the knowledge.
Anecdotally I find that some of the most successful people I know are chronically late, but I’m not sure if they are late because they are successful or successful because they are always late. I’d wager it probably has to do with whatever your reason for being late is. Being late because you are trying to maximize productive time is different from being late due to carelessness or procrastination.
I work with brazillians often, we have an office there. It's easy to accommodate as well -- I just do the same thing I do with my mother: tell her the start time is way earlier than it actually is, and then she is on time. For example if dinner is at 6:45, I tell her dinner is at 6:15, and expect her to arrive 30 minutes late.

You have to tweak it a bit for different situations (for example, a meeting, is about -15, a conference call, -10, but an after work event is roughly -30 to -60, but works well.
