Edited for more accurate depreciation estimates.

No, it's the absolutely correct way to think about buying things. I didn't spend $1,000 to get a great phone to use this month, then throw it away next month. In business, you buy equipment, you typically account for it's cost over it's useful life, i.e. amortizing and depreciation. In your personal life, it's no different, you need the right framework to correctly evaluate these decisions.

And secondly, I didn't pay $400 extra over an iPhone 8. I'll own this phone at least two years. Historically an iPhone is worth roughly 30-50% (edit) of purchase price in two years. So my two years cost of owning an iPhone X is going to be (roughly) $300-500, and an iPhone 8 roughly $200-325, only a little more than a $200 average difference. A cheap Android phone only costs $200 but might only be worth $50 in two years, so it's only about $450 cheaper than my iPhone X.

Note that I'm ignoring service costs, because they should be the same no matter what phone I choose.

While this is the economically accurate way to view your actual costs, it can be used in a bad way to think is if you don't quantify your economic benefits. If there aren't any economic benefits, admit you are paying for the badge/prestige. And ask yourself if that's worth it.

In the case of the iPhone X, it's the fastest phone with the best screen, and best camera. Am I going to get $10 a month or so of benefits from them? I think so. Would it be worth $40 a month more? Probably not.

That's because long distance at UHF and up requires clear line of sight. And that requires at least one end of your setup being up very high on towers or buildings. Height is the reason the cell phone network works. And height is the reason mesh networks don't. Height costs money.
Yeah, but Shanghai has nice public toilets. Dead bodies around are bad, but properly working public toilets are a very, very big, unthinkably big advancement over other Chinese cities.
This is not FUD. It is a design flaw.

It is now widely recognized that the header component of the JWT token cannot be used except to reject a token, making it pretty close to absolutely useless (except for debugging.)

HOWEVER. Before this was recognized, most JWT implementations were broken and were easily susceptible to the most basic of downgrade attacks.

Downgrading from asymmetric to symmetric was a slap in the face for obvious reasons, but that's just the last round of problems. The early problems were even more ridiculous; many libraries would readily downgrade to 'none' and turn off protection altogether.

Not just Amazon Cognito, but Google's OIDC implementation, and indeed, all OIDC implementations, use JWT. JWT implementations today are hopefully no longer susceptible to basic lapses in security.

But there's good reason for its reputation: the way it's designed lead to these trivial downgrade attacks. Having the token specify the algorithm was a bad decision, and it lead to bad implementations. Importantly, someone implementing JWT today could easily make some of the same mistakes if they aren't careful.

I hope a future JWT release entirely removes the information from the token and just forces the client/server to agree statically.
This may be a bit pedantic, but the phrase the author uses in his disclaimer "Experts agree that cryptocurrencies are a bubble." bothers me because it's kind of misleading.

The actual fact at hand is ~96% of economists think that the crypto market has been subject to a massive speculation bubble as of November. While that's sort of close to Roman's disclaimer, there is some nuance that ought to be given, since a) 4% of professionals dissent, and b) the question asked of economists had a temporal element to it, and they might have answered differently if the market hadn't tripled in value in as many months. It's the difference between 'the housing market is in a bubble currently', and 'housing is a bubble'.
It's true, by fair I mean being able to match minimum wage income for a small size fan base (10k fans approximately). This also depends where they are located at.
I've found that mental models -- even very abstract mental models -- are often domain specific, and benefit from domain expertise.

The most general mental models I have seen come from consultants who hop from industry to industry (SWOT for a business, of the BCG matrix) but even they are specific to firms and companies. Broadly speaking, these are often adaptable to any group effort.

There are a lot of books on these mental models or "strategy frameworks"

Thanks for the clarification on the headers part, though. As I said, I am no expert on TLS, only work on micro services that don't have to be heavily secured and have done work with OAuth and noted that API keys aren't much favored anymore.

I really a am a thoughtful, well-rounded person, it's not my fault that the Internet world won't accept me, or perhaps because Y-Combinator has a particular agenda.

What do you find as vaporware? I don't think they are offering vaporware, but their marketing is doing lot of hype hoping to enter into the startup ecosystem, but are failing miserably due to their traditional focus on selling to large corporates. I have attended IBM sponsored conferences and I was floored by the the reach they have for their cloud offering, especially on large firms and Govts. Agree that Bluemix, as an offering is nowhere as polished as AWS is, but they do have a good business going around it.

What's treacherous about JWT is that the programming interface is extremely simple and pretty closely approaches the ideal of what developers would want from secure clientside storage. It's a great interface, but terrible crypto.

Perhaps that he could have done more, earlier, but choose the money instead.
There is no lost opportunity cost. Apple or the service providers are proving zero interest purchase plans. My iPhone X costs around $42 a month for two years, then I own a phone that is likely still worth about $500.
It probably won't, but it's interesting to try.

I ran some tests of my own with simulated automated trading strategies over the past few years of historical Bitcoin price data. I used a genetic algorithm to encode a range of time parameters for MACD, along with different trading triggers and amounts. After a day or two of running it against a huge number of permutations and generations optimized for highest overall return, I came to a similar conclusion: the fittest configurations could do fairly well in automated trading (the more active ones were highly sensitive to trading fees [which were simulated] and market depth [was not simulated]), but over the span of more than a few months, a simple buy and hold strategy produced better returns in almost any time window.

Great idea - thank you for the suggestion!
I think it depends on how the organisation is using NPS. If the company itself is cheating on NPS, then it’s cheating itself.

It’s like “Capital A” Agile. Sure, it’s easily gamed, but only only screwing over yourself when you do that.

"Amazon uses JWT" and "Amazon knows what they're doing" are not unreasonable statements, but it doesn't follow that "therefore JWT is now fine for everyone".

You can make that argument for a lot of different footgun specs. I'm not saying JWT implies broken. I'm saying that JWT plus sub-billion-dollar-company-security-budget often leads to disaster. I'm also saying it's an unforced error, in that people do that in order to solve a problem they most likely don't have. It's clear that some people can do JWT correctly, just like e.g. some people can do OAuth2 correctly (to add another example to your list: Google/GSuite-as-an-IdP). That doesn't make it a safe and well-designed spec, and it doesn't make it great general advice.

6 Types of Dudes Being Mad in Their Cars on Video
You are not screwing it up as much as you think. A zero rating has the same impact as a 6 on NPS.

0-6 counts as a-1

7-8 counts as a 0

9-10 counts as a +1

NPS is an average of these numbers so if every user gave a seven or eight, the NPS would be zero (which is a mediocre but not terrible NPS score)

Slightly OT, but I wanted to know if there's any group/forum where we can read and discuss papers regularly?

> encrypted SWAP

When I was setting up dm-crypt for my Linux dev box at work I opted for using an encrypted swap as it really made sense: why keep on-disk stuff encrypted if swapped memory is in plain sight.

It turned out to be a somewhat bad decision, because when the system did run out of memory (thank you, Firefox and Skype) and began swapping, the whole box just freezes as the kernel was too busy encrypting more and more stuff, not having time to even run the OOM killer.

Maybe the systems use unencrypted swap to avoid triggering such bugs in default setups.

I agree strongly that JWT is badly flawed, and that criticisms of JWT don't constitute "FUD". JWT's uptake has been alarming given how little cryptographic engineering input the format seems to have received, versus how complex it is under the hood.

That said:

Asymmetric crypto is a crypto code smell. You use it when you absolutely have to because there's no other way to express what you're trying to accomplish. It is much harder to get public key crypto right than it is to safely use a "Seal/Unseal" AEAD interface. One of the things that alarms me about JWT is that it's a format that presumes developers might want to effortlessly switch between symmetric and asymmetric crypto, as if they were just two different ways of solving the same underlying problem.

I wouldn't by any stretch call social media "all evil". It has its problems, a lot of them. But, for me personally, it's just an extension of the rest of the internet, where I encounter people and ideas that I wouldn't otherwise stumble into. I grew up in a fairly poor, extremely white setting and social media (and its precursors, IRC and the like) was, no joke, pretty much the first exposure I had to people who were not white Americans. Meeting those people, having to get along with them, was a pretty big formative thing that wouldn't have happened without these tools. Or, in the reverse, watching the GamerGate thing happen clued me in early that the trolls and harassers that now do the alt-right thing had a certain kind of power that needed to (and, it turns out, wasn't) defended against, that they were not just "internet whiners" but were creating their own extremist political factions whether they knew they were (I think they did) or not. And, today, through idly browsing Twitter when I have a little downtime, I often see drift through my timeline the kinds of thought-provoking links and threads that make me aware of valuable and viewpoint-broadening ideas I wouldn't see otherwise.

I wouldn't say a word in defense of television, though. Being at my parents' for Christmas has made me uncomfortably aware of just how loud and penetrating those commercials-every-six-minutes are. And it's very, very one-way.
Obama's legacy is already dead, though.

>There is no such thing as an overpriced item in a free market as long as the quantity that Apple can make in a given time period matches the quantity people are willing to buy.

That's the market perspective, but there's a value perspective as well. For example, my kid loves blind bags (no more youtube I think...) These companies want to sell him $0.05 plastic dolls for $5 and they prey on his gambling response to do so. These things are not worth anywhere near $5 except from the perspective that commercials can make my kid want them.

Such a line of thinking is at odds with the ideologies of our time. If it were true, it would diminish the potency of many concepts like inherited privilege.

This is absolutely correct! After spending a lot of time trying to understand why building machine learning models is so difficult, I came to the same conclusion that "feature engineering" is the key to building high performing models.

While feature engineering's importance is generally recognized [0], it's unfortunate that there aren't more tools and formal methods for applying it. Personally, I am a developer of an open source python library called Featuretools (https://github.com/featuretools/featuretools/) that is trying to change this for tabular and multi-table datasets. We are working hard to make automated feature engineering available to everyone and have a list of demos for people to try here: https://www.featuretools.com/demos.

It's also worth noting that deep learning is changing the need for feature engineering. However, it primarily works in cases where you don't need interpretable features and you have plenty of data. This means that it's biggest success have been in images, audio, and text problems. For all other use cases feature engineering is still a necessary step for applying machine learning.
