> I think there's a lot of subtlety being missed between dynamic range and resolution. For example, I think your JND (just noticeable difference) assumption is incorrect; my understanding of the scientific consensus is that a 1db difference at any volume is consciously perceivable to "normal" human hearing (and 3db to virtually all humans), and a 0.2db difference has been shown to be subconsciously perceivable by most.

The Wikipedia article about JND seems to imply that the general 1 dB rule may not necessarily apply near the limits of perception. I haven't found a whole lot of more detailed information; however, the table I linked in the edit to my previous comment seems to indicate that the JND in dB gets much higher at very quiet volumes.

> For example, the point made about near infrared being invisible to all humans is obviously false: most humans can't, but a certain percentage of blue-eyed humans can see near infra-red (including remote control IR)

The article does mention that at some IR remotes can be visible:

> Can you see the Apple Remote's LED flash when you press a button? No? Not even the tiniest amount? Try a few other IR remotes; many use an IR wavelength a bit closer to the visible band, around 310-350THz. You won't be able to see them either. The rest emit right at the edge of visibility from 350-380 THz and may be just barely visible in complete blackness with dark-adjusted eyes. All would be blindingly, painfully bright if they were well inside the visible spectrum.

It has a footnote with more detailed information:

> The original version of this article stated that IR LEDs operate from 300-325THz (about 920-980nm), wavelengths that are invisible. Quite a few readers wrote to say that they could in fact just barely see the LEDs in some (or all) of their remotes. Several were kind enough to let me know which remotes these were, and I was able to test several on a spectrometer. Lo and behold, these remotes were using higher-frequency LEDs operating from 350-380THz (800-850nm), just overlapping the extreme edge of the visible range.

I don't have enough time or knowledge to really dive in to the scientific studies. That being said it's worth noting that a large number of studies that have found no perceptible difference between CD-quality and higher-resolution audio, and (as you mention) there are a lot of ways for minute hardware differences to skew the results either way.

> Dithering is a kind of compression algorithm that encodes a greater dynamic range within a signal with an artificially constrained dynamic range

Dithering does more than just expanding the dynamic range: it ensures that quantization error produces a predicable noise floor rather than input-dependent distortion. This video, by the author of the xiph.org article I linked before, has a good explanation and demonstration of dithering (use the chapter selection menu to skip to the "dither" section): https://xiph.org/video/vid2.shtml

There's a whole thread about interpreting the quote debating whether it paints rich people in a positive or negative light, and amazingly nobody focused on the part that says "they think they are better than we are".

Perhaps that's what the HN audience really thinks of rich people and thus skipped that point? Someone thinking they are better than others based on wealth alone is an unmistakable negative in my book.

I wish I had discovered the wonders of attending college earlier on. I spent a good chunk of my teens and twenties in a constant state of alienation because I wasn't around people who put much value towards analytical thought. It wasn't until when I finally discovered it on my own in my mid-20s that life started making sense. It seems like that for many, the high school -> university pipeline is the path of least resistance, but if you don't have any pressure from family or direct peers involved in that kind of thing, it can fall far under the radar.

I use a Kinesis Freestyle2 split keyboard at my day job, mostly because it was one of the available split keyboards available through my work. I really enjoy it so far. The split lets my shoulders maintain a naturally open position, and the tenting allows a neutral wrist position (but unfortunately my hands are too big for the built-in wrist rests).

The only downsides were some initial soreness (I think my shoulders were used to being hunched/turned in), some initially missed keys (it turns out I used to type the letter y with my left index finger, which isn't possible with the split), and more difficulty typing one handed.

Side benefit is that I have a good place to put my coffee and snacks.

Related to shoulders, I found that raising my monitors with arms (budget option: programming books) greatly help reduce the natural leaned-over hunch I'd get from looking down at my monitor. These two in combination have greatly helped my default posture.
This is important, but some people use crappy keyboards all their life and never have problems. I think more important is learning to be in touch with your body and applying corrections if and when things start feeling wrong. Unfortunately that's the kind of thing you learn from pain, though...
Multiple machines approach can work if you have an IT person dedicated to a development team, located in the same office, with a low ratio of IT-to-other-staff.

Unfortunately, it takes a lot for management in most companies to see why this is a good idea, and why spending that much on staff ratios is a good idea.

From what I understand, the thing that changes when you have lots of money, is you can act as an investor in individual ventures that are much riskier, but with a much higher potential payoff. If you can drop $1 million without being ruined if it doesn't pan out, you can multiply your money very quickly when things do happen to go your way.

In fact, isn't that basically the entire premise behind all the VC funds that fuel Silicon Valley?

This is why they really shouldn't call it "Darwinism". I won't say it's completely certain you're wrong, but I think you're extracting way more meaning from the fuzzy term "Darwinism" than the mathematics of this concept justifies... like, waaaay more meaning. It's possible this might end up there, but only via a lot more steps. On its own terms this is like talking about how important wave function collapse is because it shows how the universe is biased towards consciousness or how it must have wanted life... it isn't necessarily possible to completely eliminate the possibility in the most rigorous sense, but there's just a hair's breadth separating those phrases from outright word salad.

Except then you still have to cover the demand from requests which bypass Cloudflare through the dnslink entry.

Essentially it's a gimmicky system which is propped up by using Cloudflare, which ultimately fails once it actually gets user adoption, in a way the tradition setup (CDN + basic or even free hosting) would not. This only works because most users don't have IPFS support currently, and if they did the servers would grind to a halt just as they would with no CDN at all.

I wrote a chapter on how cryptocurrencies work and what a 51% is in a hopefully approachable manner[0].

Basically the security assumption in Bitcoin is that at least 50% of miners are honest and work for a profit. A 51% attacker can recreate the latest blocks and remove all transactions from them, effectively the ability to reverse payments.

Hypothetically the government can gain 51% hashrate. For example China could take control of all miners there (currently more than 50%) and use them to attack the chain.

This type of attack can be detected. An extreme type of defense is to change the proof-of-work algorithm, making all existing miners worthless. This has been done several times in Monero for example.

When you control 51% of the nodes you can make them agree to anything and takeover the network. Yes, BTC is vulnerable. A few years ago China has >50% of the nodes for a bit, making people nervous.

The problem there is that then people lose faith in the network, and don't honor transactions, and it collapses in value.

I'd say it's worth doing, unless you intend to spin down the app entirely in a couple of years, just for the sake of security updates. You don't want to be in a situation where there's a vulnerability announced, and you can't pick up a fix without updating 6 versions, with all of the headaches that brings. It's worth devoting a few % of time here and there to bumping everything to the latest version and fixing any issues that come up, and maybe trying to move things that had been using external gems to any new internal processes that cover the same tasks.

This attitude is rampant in many groups and underlies much of the current hatefulness in the world.

Technology’s impact on society reflects society’s impact on technology
I disagree with the core premise of this article. By this logic, the most developed language ecosystems should be those built from languages which are the most difficult to develop for. Python is a clear counterexample with a comparably low barrier, and tons of existing modules with ~80% capability hacked together by random individuals. In practice, many of those partially complete projects are picked up and improved by others, or serve as direct inspiration for more rigorous implementations. I would argue the language and community are stronger because of this.

Lisp has been around for over half a century. It's had plenty of opportunity to demonstrate its worth in helping people solve real world problems in production. I agree with the author there is probably a fundamental reason lisp doesn't see this kind of use (maybe with the exception of clojure), but I seriously doubt that reason is that it's "too powerful."

> If CloudFlare is running IPFS naked, then IPFS seems to be scaling.

They are caching IPFS for people who don't support IPFS. They are not caching IPFS for people who do support IPFS, and instead passing the user through to the IPFS servers.

Which means Cloudflare is indeed saving their butts, because as soon as IPFS has widespread support, this falls flat on its face. Same as traditional hosting would without a CDN. Their IPFS setup may be able to distribute the load enough to avoid an internet hug crippling it (that's part of IPFS's point), but this setup in no way demonstrates that.

It's not "broken"... Python3 is just the evolution of the language. Languages change and evolve, some more and some less than others. Sure, Java or COBOL maybe have done a better job of not breaking backwards compatibility, but Python 3 isn't exactly Perl 6 here.

But hey, if some 3rd party group effectively forks the language and maintains a Python2 branch after the official EOL date, good on them. But I'd argue that using that is risky in the same way that using a Pale Moon or Waterfox is (arguably) riskier than using mainstream Firefox.
