Well, I read his article as "let's abandon standard deviation and use average mean deviation instead". I think that's what he claims.
It's not: "some people are sometimes confused by the concept and in some places mean deviation would serve better, for example here and here". It has way more aggressive tone and way wider assertions about people misusing standard deviation. Remarks about "real life" doesn't help either, especially if you don't provide even one example where standard deviation is commonly used but mean absolute deviation would serve better.

>> Which -- as someone in the financial industry -- I can absolutely confirm.

This is what he is doing: he takes common sentiment often and makes into war. "Abandon standard deviation", "the confusion started", "PhD's are confused" It's easy to like him and nod in agreement while omitting that he took it way too far, proposed things way too radical and again: didn't give one single example of stuff not working because of it.
I can see how this could be confusing. However, this is an opportunity for the candidate to communicate with me. In the real world, features are not always 100% fleshed out and sometimes you need clarification. This could be used as one such example. But, I agree, this could probably be improved a bit. Thanks for reading. :)

I'm sure it is a fine cable. Monster cables are fine too, there's nothing wrong with them construction-wise.

But I've bought a large quantity of cables (USB, TOSlink optical, ethernet, HDMI, etc, etc) both from Monoprice and Amazon (the "AmazonBasics" ones) and all of them worked perfectly, had sufficient shielding when warranted, didn't fall apart, etc. I've literally never had a single problem with any of these much cheaper cables.

OK, thanks for the explanation. So it sounds like this comes down to vendors competing and not wanting to have their code exposed for fear that others might copy their chip + code when the vender is the one paying all the fees to make the chip + code usable. I guess this is similar to Nvidia vs AMD (vs Intel I suppose), except perhaps even more entrenched and without much hope of a community reverse engineering a solution.

This sucks. Do we have any alternatives? Are there any completely open radio chips in development?
Pretty sure the personal attacks are unnecessary.
AmazonBasics are actually pretty solid, I like them. They are not what people mean when they say "buy the cheapest cable you can find".

I don't buy $15 USB cables anymore precisely because of AmazonBasics, but in general I mean, don't feel bad for spending more than $0.50 on a cable.

It's a neat math trick, but it seems more accurate to say this lets you calculate bad estimates on the back of a napkin. Unless you really think food carts carry $5000 in change.

The quantitative work I do has to do with measuring latency, where the minimum, median, 90%, and 99% values are more meaningful than the mean or standard deviation. Programs typically have a best-case scenario (everything cached) and a long one-sided tail.

Sure, you're making my point exactly. The soundbite "5% of farms in the US are using Farmlogs" sounds impressive doesn't really mean much without further qualification. In fact, I find it misleading. So did you, evidently.

There are two (at least) different definitions of "farm." One is large commercial business often utilizing a thousand acres or more. I suppose these are FarmLogs' focus?

The other is family-operated (except for seasonal help perhaps), typically less than 250 acres. I live in Lancaster County, PA where farms average 78 acres. The farm I live on (and operate) is ~50 acres and has crop & animal revenue far less than $100k. But it's still a viable farm.

Average revenue per farm in Lancaster County is $183k. That's another almost meaningless number without knowing the distribution. I'd guess 10% of the farms I know are much more than $250k.

Replying to you and parents:

> Funny I find your comments to be doing exactly what they are critiquing.

I am really not doing it. I gave specific examples of what is wrong with his article and in what areas standard deviation works. I am not defending a view that "standard deviation describes reality better" or anything like that. I am saying why his article is bad and in what areas his solution of just using MAD doesn't work. Those are quite specific things. How can you tell I am doing the same thing I am accusing him of ?
While I didn't mention any specific fragment in his book I thought it's a useful view to add it as I've spent a lot of time developing it (I've read 3 books of him and listened to many talks). There is limited space in internet forum post and proving my point would require quoting the entire book as I claimed there is barely any paragraph without nonsense or term misuse. Also my claim is easily verifiable: just start reading "Antifragile" and see for yourself.
That can't be said about his claims.

> Nassim is not saying to get rid of the concept, but more like saying a lot of people are not using it correctly.

Really? That's the vibe you get from the article ? Let's see:

>it is time to retire it from common use and replace it with the more effective one of mean deviation

>Standard deviation, STD, should be left to mathematicians, physicists and mathematical statisticians deriving limit theorems. There is no scientific reason to use it in statistical investigations in the age of the computer

>as it does more harm than good

>It is all due to a historical accident: in 1893

He is not saying that some people in some situations misuse the concept. He is saying the concept is dangerous and should be disposed of. I get that he is easy to like as he picks on groups not generally liked but let's stick to what he is actually claiming instead of softening it for him.
Again, he doesn't give one simple example of a situation which could be handled better by using MAD instead of now used standard deviation.

A cousin of the superflex antenna wire the "trail radio" ham radio guys use, or "litz wire" which is handy for certain RF coil purposes WRT skin effect.

I would imagine ultra tiny diameter wire would suffer from strength issues and fatigue failure. Something like copper plated steel "copperweld" made into litz wire would be pretty awesome. OR would it? Gold plated into ultra fine diameter stainless steel insulated individually and braided into a LITZ wire.

Litz wire is not cheap, even the Chinese stuff is significant fraction of a buck per foot.

If you'd like to see a cable that costs $600 and is fairly priced the Pasternack company sells truly exotic aerospace microwave cables that are quite expensive. You know, to hook up the antenna on your space probe, that kind of thing. Built by hand, individually tested and swept on a network analyzer, that kind of thing. I buy .mil surplus stuff, made by them, from ebay (not new). And going the other way if you do broadcast engineering, $600 is a rounding error when installing a 100KW rated feedline for a TV station. $600 worth of high current service entrance cable for AC power is a depressingly short length. But $600 for a USB cable is impressive in a totally different way.

Do you need your cable for digital or analogical signal? The digital signal can be corrected if there is no too much interference, for an analog signal the shielding can be more usefull.
I would pay that much for a USB cable that, whenever you blindly reached behind your PC or monitor to plug it in, would always be oriented correctly with the plug. Think of all the time saved.

It's nice when you can have a self-aware laugh occasionally.

This is clearly self-parody from a publication that I gather is serious about audio hardware, right up to the edge of woo-woo imperceptible stuff, but probably not over that line.

A lineup of digital interconnects, which by definition are either perfect or have obvious signal dropouts, combined with language like "neutral without sounding bleached, dynamic without sounding piercing, detailed without sounding analytical" is a comical amplification on what I'm guessing is their usual review style.

This is The Absolute Sound's equivalent to the fake HN frontpage that makes the rounds now and then.

[edit]

Evidently, I was too quick to give them the benefit of the doubt. It seems most of the defense around audiophile-grade digital cables is that they "reduce jitter" (which somehow then translates to noticeable changes in different areas of the audible spectrum that can be described in wine-spectator terms) – does anyone have a good link or explanation on this principle?
Indeed. You can imagine pretty expansive definitions, and whatever definition you come up with can create potentially undesirable incentives.

I don't know whether Comcast is using IP to deliver their video-on-demand services to your cable box, but let's assume they are. That IP bandwidth is above and beyond whatever you're paying for as a "broadband" connection, but that's just accounting: It's all packets in the end. Is it "neutral" for Comcast to be able to use that bandwidth to provide you with movies and TV while restricting NetFlix to your capped/metered "Internet" bandwidth?

If NN would disallow such restrictions, then Comcast really is a low margin dumb pipe provider. Some people love that idea, but it doesn't encourage any of the existing broadband providers (maybe sans Google) to keep spending tens of billions of dollars to roll out faster and faster networks.

If NN doesn't apply to these services, then of course Comcast will simply package up as much of their IP-based applications and content as possible into proprietary interfaces with your TV and other devices while making the bandwidth available to "open" IP applications commensurately smaller.
Hi, American here. I think the problem here is that memes are actually not common in public U.S. discourse. One may use it in private discourse with friends, etc. but when they represent a large software organization the onus is on them to be diplomatic and take care not to offend their public.

From what I gather there is a number of algorithms that work pretty well, but only on certain datasets and for certain parts of the world. For example, one approach could be flawless to extract highways and on and off ramps in the US, but the same algorithm may struggle with French roads.

Importance would play a factor if there was any difference. Yeah, I wouldn't buy a $150k 14.2 audio receiver. That's way overkill, and way out of my price range. But a theater owner might, because it has the hookups he needs and provides incredible sound quality. That's what's important to him, and there's a difference between that receiver and an iPod.

In this case, there's no difference between this $700 cable and a $5 cable from Amazon Basics. It's not about what's important to the person, it's about them not realizing they're being ripped off.
Has anyone on HN been tempted to pander to the audiophile crowd?

Actually some people objectively (as in 'visible on MRT scans') enjoy certain things more if they know they are somewhat superior, even if the 'superior' thing is the very same thing as the control 'inferior', just labeled differently.

There are examples and references in "Thinking fast and slow" by Daniel Kahneman.

So the sellers of the $700 digital cable actually sell more enjoyable experience to certain (gullible) people, and do it exactly by putting an exorbitant price tag and raising hype around an otherwise ordinary USB cable. They are not in business of selling exact sound reproduction; they are selling exquisite experiences. And for an experience, emotional details are more important than the dull objectivity of spectrograms.

Imagine that you receive a pen as a gift from your loved one, nicely wrapped and solemnly handed. Compare it with an experience of owning the very same pen model which you hastily bought in a store for $10 because you needed something to jot with. The elevated joy of using the gifted pen is not in the pen, but in you and your experience, your memory. Same applies to audiophile equipment, collectible postal stamps, etc. The material thing just serves as a reminding token.

Would interested parties still be concerned about the (additional) cost

Yes. This is the whole point. The telcos' will extract rents from any profitable biz model. The more profitable, the larger the extracted rents will be. The net result is that, if people feel that the value they are creating will be expropriated by a third party on poor terms, those services will never make it beyond the cocktail napkin stage. And if...the founders are still optimistic and willing to let this happen...the VCs are not likely to play along...knowing what will predictably happen. As long as either of those two factors is in play, the economy ultimately will suffer in the sense that those services will "never happen" if people take that approach. Or, at least that's the argument if I understand correctly.
