Your claim that the authors were paid for it is just a lie you made up, right? That's why you have no specifics about who paid them.
Imagine if a bunch of investors walked into the Homebrew Computing Club [1] in 1976 and offered to buy anything and everything its members made for $1 million. With the benefit of hindsight, blockchain is the story of a neat database technology trashing its near-term prospects by marketing itself as a currency.

Most webpages don’t have the reach of a mid-sized city newspaper in the 20th century. A few approach the reach of a major city newspaper, wire service like AP or Reuters..,

If you look at the 1990 circulation numbers, they are small for mid-sized cities, and even for large cities. The NY Times circulation was just over a million, there are hundreds of webpages with that kind of reach now.

Blockchain is simply a sexy term for a distributed ledger, which has its place in a limited set of use cases.

My semi-regular Lyft ride to work has increased steadily from ~$7 to ~$10 over the last 3 months.

Given the video game crash of the early 80s, it's entirely likely that the Seal (or at least the principles behind it) was part of Nintendo's earlier successes. Whether it's still relevant today is questionable, but I wouldn't write it off.

Amdahl's law strikes again.
In the UK we can do that without the blockchain, in many situations, thanks to the real-time payment system [0]. So for me, a normal bank transfer is free and easy, whereas every time I've tried to do something involving blockchain it's meant delays, fees, and messing around on shady-looking websites.

I take the point that in other places the norm is a lot worse and blockchain systems are producing better results, but it won't be long before banks get their act together and improve their services to match modern expectations (for fear of becoming obsolete), and then the blockchain competitive advantage is gone.

Pretty sure steel wool will have the same issue as the steel brush.
The fundamental shift is that more and more businesses are exploiting consumer trust. The shift to online makes it easier. In face to face transactions, the emotional and psychological makeup of a business's sales staff bound what is practical at scale...it's hard to hire a lot of psychopaths into low wage high turnover jobs. The low wages make it hard for people to rationalize continuously taking advantage of trusting individuals, a business really needs high ticket goods and commissions to make it work (e.g. car sales). With automated online transactions there are no ordinary staff who might loose sleep at night over abusing trust.

That's the other way around most of the time where I lived (Continental Europe and London)

Only in London, people I know have had both experiences. Letting agencies are really the one pushing. For the landlord, a paying tenant is a good tenant, there is friction in changing tenant: you can lose 1 month rent or need to do some refurbishments. Even missing a few weeks can mean losing any benefit of keeping the same tenant at the same rate for 1 or more years.

Letting agencies offer a service to both the landlord and the tenant. As a tenant you get a certain level of service, like repairs or maintenance. As a landlord, the agency offer vetted tenant, management and various guarantees. They are the one pushing for rate increase as that's what they take their share from.

The real problem with renting is the underlying skyrocketing price of housing. You can't escape it.

The idea of a neutral "third party"(!) operating a globally available transaction ledger, with standardised APIs and agreed meanings to contracts and data structures is appealing to everyone in every sector.

the sizzle of blockchain is enticing, it solves huge problems that are darn well intractable without "disruption".

for example in finance the global clearing system is an embarrassing hodge podge that only benefits the fraudulent and the incompetent - and replacing that completely over night has enormous attractions for pretty much every actor. but ... it is really a silver bullet - if it was so easy to replace global clearing, to get everyone agreeing on one representation of a trade or an instrument or a hundred other things i honestly never understood, if it was that easy it would have happened.

this sort of sector wide cohesion comes with either one dominant player or many years of government level negotiations

The web only blew past everyone in most areas because there were no global communications between parties at all in the areas the web now dominates (cf social media vs international shipping documentation)

How do you know this? From the video I saw, the advanced sensors didn't pick up the pedestrian at all. I would have expected some braking forcing the human driver to move forward abruptly. It would have been interesting to see the tail end of the video before impact to see if the car made any evasive moves at all. It wasn't evident to me the AI was 99.9% better in that situation.
Interesting, though I wonder if using multiple $1k lenses is as cost effective as buying one 16" telescope (<$3k) and a sensor/camera ($1k?) that would give ~3x more light gathering capacity than the array of 24 lenses.

- There seems to be confusion here.

- There is general systems theory [0] and within that systems engineering[1] where you will find software systems [2]

- OP is most likely talking about how to use of general theory of systems in different domains and not specifically software systems.

- If one considers JQ, SED and "One input stream, one output stream" and then compares that to a model of a system using a CLD (Causal Loop Diagram). A CLD is effectively "An input, followed by an output"

- Another word that could be used for "input stream" would be 'flow' from system dynamics [3]

- One could apply general systems theory (the abstract concept) to just about anything

Interesting. Terry Myerson was the head of the Windows Phone division through WP 7, 8 and the early part of WP 10 and bore at least some responsibility for its (lack of) success before being promoted to head of the Windows division as a whole. The inclusion of the much derided tie-in ads in Windows required at least his tacit approval.

The general impression was that he was one of Satya Nadella's darlings. One wonders what finally felled him?
I once came across a curious anthropological account of the importance of fire is a section in Feliks Koneczny's book "On the Plurality of Civilizations"[0] written in the 1930s. (The OCR or transcription isn't great, but the text is still able to be read.) Others might find it interesting.

RF propagation is complex and subtle, and many reasonable-sounding ideas for optimizing it end up not working in real life. At 5 GHz a fade due to multipath interference (https://en.wikipedia.org/wiki/Fading) can be less than 1 mm in size, so waving a device around doesn't capture everything important about an area.

There may be a good idea there, but you'd have to build it and test under a variety of conditions to see if it really helps.
The vagueness of Blockchain reminds me of the same “Cloud” vagueness. CEOs and CIOs read these articles about how great “Cloud” is and how everything is moving to “Cloud” and they turn around and declare things like “I want Cloud” and “We need to work on Cloud!” and “Invest in Cloud”. Just parroting what they read in HBR or what some IBM consultant told them. Then a whole bunch of money is spent on “Cloud” with often not much to show for it at the end, besides a bunch of opportunistic Cloud providers getting rich.

Rinse and repeat for Big Data, ML, AI, Bockchain, and whatever the next fad will be.
I can come up with three reasons. First is to remove beef residue before cooking chicken. Second is to prevent chicken from sticking - a clean grill with fresh oil sprayed on it works best. Third is that, when running a grill for a number of hours at a time, you generally can't afford to shut the grill off to clean it.

Bitcoin needs blockchain to verify that a bitcoin is authentic.

I have no idea why a company would use blockchain for logistics or file storage considering how its massively expensive to constantly pay miners for transactions.

My centralized server can do everything needed for logistics or file storage.

Crypto does not equal blockchain. Blockchain has a huge number of potential industry uses other than cryptocurrency. IBM has done a lot of work with companies making blockchain products that don't involve cryptocurrencies. When multiple companies are in a shared relationship they can benefit greatly from the tech. There are government regulation opportunities keeping track of sales and trades on regulated public markets. Crypto is just the craze that got the word out. Even calling crypto a failure feels like an over statement.
In my humble opinion, the greatest sin of the USB C standard is the lack of introspection. Given the huge amount of possibilities, it should be possible to question a USB C socket with a cheap device what Alt modes it is capable of, what device roles it is capable of, what USB PD it supports etc.
We didn't test this with Express Pool but Pool in general is a different animal since the prices are so cheap to begin with, there's not a lot of variability that can come into play and affect the pricing.

Plus, Uber takes a huge loss on Pool and Express Pool especially when they first launch since they want to offer low prices to riders but they don't know the match % rates yet.

Sure but I'd argue that there are likely to be more similarities amongst people with 2,000 hours experience than there are amongst people with 1 year of experience. 1 year could mean anything from "watched three udemy courses" to 4,000 hours of hands on keyboard in a full time position + hobby projects.
true.

OTOH, consider the value of the satisfaction you feel pushing back against a business that rips you off.
Given the fact that Google apparently stores the pictures you've taken with your phone (at least on Android?) and Snapchat saves all of the pictures you've sent with it for an unknown amount of time, wouldn't that reasonably mean that both companies are storing child pornography on their servers?

If you agree with the premise that regular equities markets provide value (in that competitive allocation of capital leads to a more optimal result than centralized allocation), it seems to follow pretty naturally that derivatives and options provide value by allowing participants in the market to turn more nuanced beliefs into a position than they could otherwise.
Yes -- these glasses trick facial recognition software: https://www.cs.cmu.edu/~sbhagava/papers/face-rec-ccs16.pdf

> In this paper, we focus on facial biometric systems, which are widely used in surveillance and access control. We define and investigate a novel class of attacks: attacks that are physically realizable and inconspicuous, and allow an attacker to evade recognition or impersonate another individual. We develop a systematic method to automatically generate such attacks, which are realized through printing a pair of eyeglass frames. When worn by the attacker whose image is supplied to a state-of-the-art face-recognition algorithm, the eyeglasses allow her to evade being recognized or to impersonate another individual. Our investigation focuses on white-box face-recognition systems, but we also demonstrate how similar techniques can be used in black-box scenarios, as well as to avoid face detection.
> GPU acceleration in scientific computing

> it's still hanging around but realizing a 20% speedup on certain classes of problems

It really varies though. In grad school I felt like god when some molecular dynamics simulations running on my pair of GTX 760s finished faster than the same thing running on my advisor's 96-core CPU cluster.

Point taken, though, that it was over-hyped. There were lots of conference presentations with GPU-acceleration in the title (kind of like deep learning is now).
Lyft has switched to an upfront pricing model too so it wouldn't surprise me if they are doing something similar. But I haven't seen any examples that are as bad as with Uber, where I'm constantly seeing big discrepancies like this.

How do you know which plastics are being used by the restaurants you eat at? And what does "being rated" for heating actually mean? Does it mean that no plastic or other chemicals from the bag actually gets in to the food? As a consumer I have no way of knowing.

It doesn't seem to work at all for me. Not sure why, I've checked with Chrome and Firefox on Linux (using i3 tiling window manager). I see the text outline on the left and the white pane on the right, where I assume I should see a mindmap. I see nothing but white in the large right pane, so maybe there's something you're supposed to do to get it to draw the mindmap, but I can't figure out what.
Wonder if you could do it on the cable with little embedded LED lights. One end turns red for "charging" the other turns blue for "supplying power". Would add to the BOM cost on the cable for sure, but it would not only be cool looking but rather useful.
The features aren't a bad thing, it's good to have them, and it's good to have an OS finally that improves more than once every four years. I have no real issue with their efforts towards supporting 3D printing natively, for instance, even though I currently can't use it myself.

It's the anti-features I have a problem with, like the fact that Candy Crush has to be preinstalled on each domain user in a corporate environment. The general unreliability of the build cycle needs some serious rethinking as well, right now it takes five months to get from a new build to a stable release... and builds are only six months apart.
We tested all different times and traffic levels but in general, Uber's algorithm is terrible at predicting traffic since they use their own internal maps system (as opposed to gmaps or waze).

How should we view these layoffs in comparison to say the ones done by twitter? They did a bunch of layoffs a year or so ago and it’s market cap has recovered significantly since then.

The first wave of layoffs Snap did were related to the hw engineering org. AKA those glasses they mad, right? They were a commercial failure and a distraction so I viewed that as largely a positive sign.

This wave of layoffs seems like they are trimming the fat in sales/marketing, again not necessarily a bad thing. Other companies like twitter have done this and gone on to recover.

I think the biggest problem with Snap right now is how similar it is to Instagram now that Instagram has cloned stories. Twitter served a far different use case from Facebook and they seem pretty safe now that FB is backing away from news.
