>Mass-produced sensors now cost less than a dollar apiece, even for hobbyists; high-speed broadband and cheap cloud computing mean that a city can collect and analyze reams of data in real time.

Does the author believe 'sensors' is a term for some generic commodity product akin to rice? Yes, some sensors cost less then a dollar (but some sensors have cost less than a dollars a piece for decades) but other sensors (I.e. LIDAR, EDS, neutron detector) cost thousands.
They're well understood by anyone who has used these technologies professionally. I probably should have been ore precise with my language, though. It's really a grey area as to where the boundary is and it depends a lot on your specific application. But as a general rule of thumb, my feeling is that for tens to hundreds of GB, you should consider it. And for TBs or more, you almost certainly want to be doing something distributed. Hadoop isn't necessarily the best option then, but it's a powerful tool. I don't know if there's any resource out there that really goes deep into the tradeoffs involved though. There probably is, given how popular the subject is, but I'm not aware of one.

The problem with the article is that if it's for a general audience that doesn't understand the tradeoffs of a system like Hadoop, it really paints a picture that it is just a bad, slow tool. It barely acknowledge just how rigged the comparison is at all, aside from mentioning that you might need something like Hadoop for really big data in the conclusion, while it is peppered with unnecessarily snide comments about Hadoop that will probably be more memorable. I think it is liable to leave readers more confused about the tradeoffs involved after reading than before.

Transcript of text exchange with my sister just yesterday:

SISTER: Any interest in learning blockchain development? I'm getting into that world and will need someone reliable. Plus, I'll be able to expose you to projects and get you consulting gigs. I know you have your new job and all it's demands. Timing prob isn't good but figured I'd check in anyway.

ME: No thanks. I know the blockchain technologically is a thing but every application of it I've read about (e.g cryptocurrencies) looks like a scam perpetrated by people who think the problem with society is being social, misunderstand the history and purpose of the Federal Reserve system, and/or believe the idle rich deserve to be richer. I understand there's a lot of stupid money washing around in those circles. Just make sure you're playing with somebody else's money.

SISTER: I have no interest in the ICO crypto currency application. I'm more into the smart contracts. Id like to apply it to healthcare (help end the opioid crisis). Or the credit reporting agencies...get rid of them and allow individuals to control access to and use of that information. So many applications that are just beginning to scratch the surface. My MBA thesis project is using blockchain to help end the opioid epidemic through better diagnosis of individuals more prone to addiction or just getting it to sell on the streets.

ME: I've seen some discussions of using blockchains for things like certifications or logistics. They've all seemed kinda hand-wavey to me. Like yes there may be some minor efficiencies to be gained by moving to a new tracking/trust system. But the real issues will still be the humans at the ends of the transactions. I'm not sure how the blockchain fixes that. But maybe you can persuade me. Fortunately, the technology itself is over my head. I've seen some python tutorials I could probably dig up for you. But I don't have time myself to try to pick it up.

SISTER: The ledger platform we are currently planning to use (hyperledger by IBM) has some free training but apparently you need a basic understanding so I'm sure it will be way over my head.

ME: I hate to be cynical (j/k I love it) but I'm sure that's the point. IBM would love to convince the next generation of MBAs they need Hype(r)ledger™ and its attendant battalion of IBM consultants to reimplement a table or two that someone in the org already has working like a charm in a simple spreadsheet.

SISTER: Well duh...they're for profit public businesses. I would be worried if that wasn't their reason. That doesn't mean that the applications hosted on their platform aren't practical or solve a problem that prior technology couldn't. 90 people die every day from opioid overdoses ... what if your technology could reduce that number to even 80? Profits are secondary. Check out blockmedx.com when you have a second.

So there you have it I guess: blockmedx.com
It sounds strange that a company with 'no assets' was bought for a non-negligible sum.

If you had said 'it had no physical assets' or 'book value of its assets was zero' or similar, it would make sense.

But if literally had no assets, what was the buyer buying? The name of the company?

Back on topic: even after the 5MM exit value is known, it's impossible for me to value the shares of an employee who owns 1% of the shares. The value is almost certainly between zero and 50k, but without seeing the share docs, no one knows.
This is the sort of boring tit-for-tat flamewar that we don't want here, and that ultimately ends up with people yelling uncivilly at each other. Please don't do this again.

Sorry, I mean microsecond-level competition. I agree regarding algorithmic trading.
That's a great analogy!

I want to suggest a related tactic, which is to relate your problem to a secondary goal that another part of the business has.

For instance, your marketing team wants your site to be ranked in the top 10 on Google for a certain key phrase where it currently ranks #100. Marketing can probably quantify the value of that improved ranking. But Google penalizes sites that run slowly.

Not to mention the studies that show most users bounce if a page takes more than a second to load; and a good marketing team will consider your (presumable) bounce rate atrocious and be trying to improve that.

The marketing team can be your ally in the fight for resources to fix this problem.

What's the cost per hour in customer service hours and in lost sales if the site goes down entirely? Quantify the likelihood of that outage based on current traffic rates. Recruit the customer service and sales teams to your cause.
> My own understanding of the term "well understood" is that it is synonymous with "widely understood". If many people are still making the mistake of using Hadoop when those costs outweight the benefits, it seems that understanding isn't quite wide enough.

I's entirely possible that 9 out of 10 people on a project using Hadoop know it's a waste but there are non-technical reasons for doing so. Resume padding and PHB demanding some technology of the week would be the two most common ones.

That said it probably is contradictory much of the time. I'd say the majority of current developers don't know about the simpler tools.
Of course it does. The bare minimum to be "safe" is much different than strict internal standards. All rules are not created equally, and breaking different rules should be treated differently. This is why the purposeful misdirection in the headline matters - it is not true or accurate.
Maybe, but please don't rant like this here. It just lowers the signal/noise ratio even further.

You're right, I was oversimplifying the situation. The council threatened oBike with fines, so they came to arrangements to have cleanup crews, which then cost too much money, causing them to pull out.

I wouldn't say oBikes were reasonably popular. The only people I ever saw riding them were tourists in St Kilda, and homeless people who had broken the locks off them.
There are lots of good thoughts here. If the only thing is to make you more marketable, then consider if there isn't something else less time and money consuming that would give you more.

I think college has more to offer, but it really depends on what you want out of it and how hard you want to work.

At the moment, the economy is booming. You could always go back to school during the next downturn. When it's raining soup, put out your bowl and all that.

I have seen professional doors shut because of a lack of a degree, or a lack of a masters, or a phd. It all depends on what you want and what tradeoffs you're willing to make.
They all are, ICO IS the product.

So in the past I've advocated password algorithms (sometimes called password formulas):

https://penguindreams.org/blog/password-algorithms/

I felt like they could bridge the gap between a regular person who is weary of having to look up every password using a password manager (although a lot of them make it easier with browser plugins and phone apps, but it's still an extra step).

However, in light of the recent Gentoo vandalism, it seems like a user had their password formula figured out. Algorithms do guard against credential stuffing; that particular person was most likely specifically attacked. If you have a strong formula, it should take at least 7 or 8 passwords to begin to figure it out.

At a minimum, if you have non-tech friends who use a single password for everything, start them off easy: You should use a manager. It's the only way to guard everything. But if they don't want to go that route, at a bare minimum, recommend that they need three passwords. One that's highly secure for banks, employment and government. One insecure for everything else. And finally one for your e-mail which should be shared with nothing!

Password algorithms are a step up. It's a trade off of course: you are protected against credential stuffing and you don't need a manager; you can have a different password for every site without having to memorize a hundred password; only the exceptions to stupid password rules. The trade off: your algorithm probably sucks and if you're targeted specifically, someone can get to everything.

Every aspect of security involves trade offs. The various password management choices, along with their advantages and disadvantages, should be taught in high school.

Why do you deserve the privilege to control our lives?
Not at all experienced in Lisp, but I believe this is the core algorithm in that parser...

(cond
((and (binop? $next) (> new-priority priority))
(scan)
(loop (list op result (parse-expression new-priority))))
(t result)))))

...and is what amounts to the widely-used "precedence climbing" algorithm described here:

https://www.engr.mun.ca/~theo/Misc/exp_parsing.htm#climbing

I like to think of it more as a clever refactoring of recursive descent that condenses all the very similar recursive functions at each level into one which is parameterised by level, and also handles associativity by choosing whether to recurse (right-associative) or loop (left-associative) with the RHS after a binary operator.

It's actually an interesting question you can get 192 cores and 12 TB RAM in a single x86 box. At what point does it actually make sense to go for Hadoop.
Give it a rest.
> The FAO reports that 35% of global catches are wasted. About a quarter of these losses are bycatch or discards, mostly from trawlers, where unwanted fish are thrown back dead because they are too small or an unwanted species. But most of the losses are due to a lack of knowledge or equipment, such as refrigeration or ice-makers, needed to keep fish fresh.

This is so depressing...
I've never tried to follow up with which accounts/passwords have been used from haveibeenpwned, can you describe this further as I'll try this.

The "huge pw torrent" is something I can just search on torrent trackers? Once I have the list, its just a list of passwords, or includes the emails? Then they're sha-256 hashed and I need to ..unhash them?
You just have to remember the exact username/email you used in case you forget it. That can include the sitename itself, or some simple transform, but sometimes services change names... so make sure to keep records of exactly the email used for each service (or don't delete your email from them), forgetting that is worse than losing the password, since there's often no helpful recovery service they offer.
I am having trouble parsing this question. Did I miss a joke or sarcasm?

This is like asking "what about people who prefer to crank the propeller" while staring at a jet. It does not apply.

EVs don't usually have to shift gears, not because they have automatic transmissions, but because their engines can achieve high RPM and torque is similar across the usable RPM range. The Nissan Leaf, for instance, has a single gear, then only thing you can do is engage or disengage it. Reverse is handled by rotating the engine backwards, so you do need a control for the driver, but there's no corresponding gear – the easiest way to see that in action is reversing the direction while the car is moving, like you do in an electric bumper cart. With most car transmissions, you would need to stop first, then reverse, you could even cause damage if you do it while the car is moving.

I guess if you really wanted to, you could fake gears on software. And fake some engine noise while you are at it...

Yes, but you’re also doing the typical apples to oranges comparison here. Just like the ol’ “China is light years ahead in mobile payments!”. Well sure, because we have a mature credit card system that works well and the Chinese never had a credit card in the first place.

Long story short, because the economies are at different stages, the issues that China has now perhaps the US had 50+ years ago.

You’re not going to sell a product to a 40 year old the same way you do to a 12 year old.

The studies here seem to suggest most people learn better in quiet most of the time.

That said, I listen to music without lyrics myself while learning :)

I'm not sure troy shares the lists - for obvious reasons.
If one compares IPO->ICO, in that context then the SingularityNET ICO may not seem to have to forecast of "profitability" that one would usually associate with a successful public offering. However, in the context of the purpose of the AGI Token they offer, the initial demand was high and in fact overshot, pointing to anticipation (or hype, but I believe it was genuine anticipation) for the coin. It sold 500 million tokens, reaching the ceiling in 24 hours. Sales dates were pushed to allow more sales due to overselling. That points to an initial success, I think.

Looking at the purpose of the AGI Token which is to create an open AI exchange (if I understand it correctly), where AI developers use their services in exchange for the AGI token, or for other services, then looking back at that anticipation and over-sale of tokens, it appears there are interested and active investors who are looking to make this coin work. To me, that is successful in comparison to simply having a Public Offering where lots of people invest, often to only lose that money later. This seems to have a purpose.

What points to current success, the "doing so well", is the more than decent ratings a large portion of ICO watchdog sites are giving it for now (although many ICO watchers acknowledge the level of hype to date has been high).

Looking at the current numbers, you're probably going to say "meh"; especially considering the ICO hype pushed the price up, then it dwindled down to a low ebb and flow. But that isn't why I see high expectation, still, for this coin, right? It still has intentional use built into it, and according to the website the Platform Beta Release is coming in the next month or so, at which time the coin will begin to do its work.

So, for me, "doing so well" means there was meaning behind the ICO beyond just economics, the interest was there and was overwhelming, the project has code tied to the coin that is going to go live soon and (from what I read) anticipation is still there within the AI community and the investors.

But again, I ask the question here because compared to the statistics in the article above, SingularityNET appears to be... doing well.

Hashed Health & Change Healthcare over here in the South.
You are totally right, I honestly agree with you. It's an important question, it's worth asking and we should all be asking it. I think there's a lot more grey in software development, grey people may not have as much of in other fields. But that does not mean we can simply ignore the question and it certainly doesn't diminish it's importance. More than that, it doesn't diminish our responsibility.

My concern really revolves around the scapegoating and protecting developers from situations where there is more grey than black or white. But that is not a sheild from personal responsibility or moral obligation, the questions you raise are important in their own right.

> comparable to HBO’s tentpole programming?

I think this misses the forest for the tentpoles. Right now HBO's original programming is one episode per week of: Sharp Objects, Succession, Last Week Tonight, Vice and a Bill Maher special. Yes I think Netflix's better new content competes with that. Netflix supplements that with a huge array of quality third party tv shows. Non-English content is another set of moats for netflix, I wouldn't be shocked to learn that Netflix Japan has more hours of original-ish (lots of it is co-produced) content per year than HBO. Korean and Spanish might be behind but not too far and Chinese and Hindi are just a couple years away.
While I believe the comment was a joke it is also a reference to people who make emotional decisions over objective ones. I also think that many people don't realize just how many humans prefer to make important decisions emotionally. It's not something you generally learn sitting at a desk.

A variation on the password algorithm: Generate half of your password by using the algorithm. Create the other half, one per site, using a random algorithm, and write it on a piece of paper (if the site has stupid "security" requirements for the password, you can usually fit these into your random string).

To regenerate your passwords, an adversary would need both to figure out your algorithm and obtain your piece of paper.
