They're working on it. They've substantially increased their data collection on the vehicles and their delivery routes in the last decade. Their drivers union stipulates nobody will be fired solely because of sensor data, and that as the efficiency grows, the pay will grow proportionally. A driver delivers many more packages per day now than 10 years ago.

I attended a presentation from Jack Levis at a supply chain conference. At first glance it seems like a traveling sales person problem, but it's much more than that. They have contracts to pickup and deliver at specific times for specific businesses. They have to optimize which packages are on which vehicles, the route, the volume available and numerous other considerations. The combinations get out of hand very fast, you can't do anything near brute forcing. Sometimes the path which will work best looks unintuitive.

They have real time issues that come up (water main shuts a road down for 1 day, in under a minute that info is available to all delivery drivers). They have their own custom developed hardware for the scanning guns which are GPS and network enabled, they have a team of around 700 people working on their ORION project (largely optimization, many PhD's included).

Couple resources on it:

You can but complex datatypes (json) have complex (and often ugly) constraint definitions. It's not much fun compared to "look, I just want this field to be a date."
Why do you assume it's trolling? You forgot the sentence which came before here is the entire argument.

"Every new generation growing up is a new generation who will be affected by other things than the previous generation.

Everyone also laughed when I in the 90'ies said you would one day be able to score girls from being good at playing computer games."

The point is that looking at your own generation is not a good indicator of where things will go. Look at those younger generations which haven't yet been affected by what is right or wrong.

That was my argument. Girls will grow up knowing what it takes to be good at a computer game it won't just be something nerds do, but something they themselves do.

The point here is to understand what allows progress.

Sure something might or might not come to fruition but this one my predictions were based on understanding what it would take for it to be popular.

I am not trolling but 100% serious.
> the long answer: entire genres were built on not knowing music theory or disregarding it (techno, i'm looking at you).

Thats putting things mildly. The entire electronic music scene was born from experimentation. From the Kraftworks and other synth pioneers, to the beginnings of the dance scene with Chicago house and Detroit techno. From sample heavy genres like Jungle and Hard House, to synth heavy genres like trance. Even IDM was born from producers disregarding popular conventions and look how much that has since bled into the mainstream with tracks incorporating glitchy effects into pop songs.

But it's not just the domain of electronic music either. Prog Rock existed because uni students wanted to push the boundaries. Then Punk came about because they wanted to redefine what it meant to writing music and play an instrument.

So long as music remains an art form, it will be subjected to ignorant hobbyists with a creative flair. And that is what I love most about music; when people say "I have an idea, it might not work but we will have fun trying". But very occasionally, those hobbyists create something so popular they then become trendsetters themselves, like Prodigy, Orbital, Aphex Twin, and the other artists I alluded to above.
An Impenetrable Program Transforming How Courts Treat DNA Evidence
Here's a vague idea... How about a reputation ledger? My reputation will accumulate over time, and people will trust me, simplifying some transactions. For example I could rent a short-term stay at a lower rate because I am such a nice fellow and will never mess anything up.

Because my reputation has direct monetary value I would be hesitant to mess it up by being a dick, unless for a very big gain. The counter-parties will know the value of my reputation as well as the total value of outstanding liabilities against my reputation, so they will not give me any resources worth more than my current reputation capacity.

This has nothing to do with mining or coins, just an immutable public ledger. For all I care every notary public will be given a right to sign a block in the ledger, and collectively they will establish consensus.

The data is stored on a decentralized database (many nodes). I buy my house and am send the rights to that land on a blockchain. Only someone with the private keys to my address/account/whatever could send that house to someone else. The scale of the network should make it impossible for the database to be corrupted.

The whole idea here is distributed trust
Yes.

For reasons I won't get into, I went remote after working for a company for a couple years. What I gained in flexibility I lost in advancement opportunities. In my view, unless you're a very rare commodity, the workers closest to the organization are the ones most likely to be promoted.

If you value flexibility, work remotely.
If you value advancement, it's probably best to stay at HQ (if that options is available to you).
Ryan X. Charles at Yours comes to mind. Many technical founders of Bitcoin co's were behind SegWit2x, which flamed out spectacularly, and some are switching to Bitcoin Cash- eg Stephen Pair of BitPay.
This probably has to do with payments the banks are making to each other, not between banks and clients. If banks are paying each other, there's going to be a nonzero cost associated with the accounting for those transactions, and this system would remove that cost.

What I didn't understand from the article was the point about membership. If the contributing banks are the only ones using it, why is it giving information about what _I_ could do with one of these USCs - apparently nothing because I won't be able to join the chain
* Lack of names

Can't you just use records and named user defined types?

* Hard to track mutations

I feel he's mixing imperative and OOP. Its not even every OOP languages that have the self referential this keyword. Basically, I struggle just as much with this in imperative and OOP languages. The fix in FP is that you don't design things to be mutated in the first place, so you don't need to track it.

* Partial evaluation

Strange name, I think he meant partial application. Anyways, I actually think OCaml is curried, which is different to partial in that its implicit. I agree with him a little here, don't abuse this, but the feature does come in very handy once in a while. I think that just comes to learning good practice like in all languages, you still need discipline.

* High order function

I really don't understand this one. Just look at the doc-string or the function signature if you're confused what arguments the higher order function takes.

* Passing values around

I find reduce way better. How weird is it that sum is mutated outside the loop? I've seen plenty of imperative code where the mutated accumulator isn't declared near the loop, or its reused from one loop to another.

* Lack of methods

I think he's confused with namespacing? Also, methods are an OOP concept, not imperative, an FP/OOP lang could easily have them. Anyways, I find methods are one of the worst thing in mainstream OOP. That's why all modern OOP langs are adding traits. Methods are closed, so a type can't be extended to support more of them. Also they get abused as namespaces, where really the methods should only operate on the class fields.

* Lists

Well, not all FP languages are built of the same datastructures. So that might be OCaml specific. I'm sure there's libraries to fill the void.

* Lack of early returns

Minor gripe, I don't particularly miss it.
Why Men Are Disappearing from the Workforce – Money
Most of our use case is storing raw event data: user clicked on X; interacted with feature Y; was bucketed into test group Z; audit logs for subscription data points (joined, upgraded, downgraded, paid, payment denied, etc). Basically everything we care about, but that doesn't matter as a core concern of providing the service.

The main app needs to know if a user has access to entitlement A, but the history of that process is outside the concern of the app itself.

We throw everything into BQ/Redshift. Then when we find a need for it, we bring it into a separate reporting dataset in Redshift via ETL.

The nice part about this is you can join your sanitized ETL data against raw event data if you need to run a once off query like "for everyone put into variant A of experiment B, how many converted from a free trial to a paid subscription?" I haven't found a great way to programmatically recreate ETL data into BQ without recreating a new dataset every day (because of the history of immutable data). It's not that it's impossible, it's just not as great (imho) as an upsert type workflow.

Occasionally we'll have a once off query we access by hand, but that's relatively rare at this point. Jobs run around 1am and everything is ready to go when the team gets in in the morning.

You have the odd job where you have to manage distkeys, and that's rarely fun, but it's a trade off we're comfortable making.

And, while I'm pimping other people's services, Redshift + Looker is incredible.
You can describe it any way you want. It doesn't change the fact that "value" is not something which is easily defined which again the art scene is a good example but also stamps, coins, stickers, physical Pokemon cards and so on.
If you're a clothing company, the margins you can reclaim if you're able to pull off direct to consumer, are astounding.

That $60 shirt you make that is getting sold in a store like Neiman Marcus or Macy's, you're getting $12.75 for it as the maker. Stores charge obscenely for their distribution access (and for the most part they have to, their costs are very high; a higher margin store like Macy's, in good times, only has a 6% net income margin).

Ten years from now the direct to consumer segment is going to be massive. The online platforms that can generate sales referrals (distribution), are going to become the new margin-eating department stores, the middlemen providing access to the buyers. That's eg: Instagram, Pinterest, Facebook, et al. There will be dozens of more specialized players as well. Right now businesses are commonly selling (leads &or transacting) across two dozen platforms (from eBay to craigslist, from YouTube to Poshmark, from Instagram to Etsy or Shopify), ten years from now that'll be four or five dozen. Sometimes you'll get lucky and get quasi-free distribution on them virally; most of the time you'll have to pay up for reliable distribution. There will be the occasional rare direct to consumer success story that has truly crazy margins because they spread entirely virally, they'll be the magic unicorn story that gets frequently written up as the trend gets larger and larger.
There's also research into cryptocurrencies issued by central banks, both for retail and wholesale between banks [0].

You're being pedantic, but you kind of made my point for me. As you point out in great detail, all of these prosecutors object to private companies doing what they do in the name of the State every single day (extort people). Some of them are acting on the objection by suing the program, others are quoted speaking out against it, etc.

> I think it's a good failsafe. Yes, it will fail many qualified people who don't practice, but it will also fail a lot of people who talk a good game but can't code their way out of a wet paper bag.

I don't. I do R&D for a living and have next to no time to relearn those types of undergrad programming techniques because it doesn't apply to the work I do at all. Ask me to create a model for a system, implement a classifier that hits 90% in a way that no one has ever done before and publish a paper on it, I can do that. Ask me about a breadth first search on some tree and I'll look at you blankly. It seems a bit ridiculous that some of my cookie-cutter engineering colleagues(some that relied on me to help them with homework) can make it into places like Google but I can't make it past the 3rd or 4th interview. I can also assure you that none of my colleagues where I work could make it past that same stage of interviews despite having a PhD and despite them being great researchers.

Wouldn’t it just amplify it? Right now, central banks just set up swap facilities between each other. It’s akin to opening a bank account with one another. Crediting, debuting and undoing anything nefarious is cheap and easy.

I haven’t needed to yet. Much harder if your reputation doesn’t precede you. Think about applying for a full time job. How much does it help having someone internal who can vouch for you to HR and the hiring manager? Consulting is no different.
I'm not sure this is textbook extortion. Walmart is within its rights to press charges. They're simply giving the accused a chance to settle outside of the criminal justice system. IANAL though, and it may vary a lot by state. Bear in mind though, the stores usually have good security cam footage when they nab you.
And ADABAS (officially declared fully supported through the year 2050 and beyond). Most often considered non-relational too.

High-value transactional environments most often neither relational nor even running on operating system (in modern sense at least), like zTPF "because a real operating system is too high level and therefore too slow for real transaction processing needs". Current users of TPF include Sabre, VISA, American Airlines, American Express, HP SHARES (formerly EDS), Holiday Inn, Alitalia, KLM, Amtrak, Marriott International, Travelport, Citibank, Citifinancial, Air Canada, Delta Air Lines, Japan Airlines and many others.
For what fee?
I sure that's right. Also I should add that while I was never a Lift fan, it did get the job done, and worked reasonably well for the limited stuff I needed to do on that project. It's just the best example I can draw on from personal experience. I think it's illustrative of problems I've seen with functional programming "in the small" in JavaScript, Java, and numerous online examples in a variety of languages.

I still come out with advertising jingles from the 90s that embedded themselves in my conscious as a teenager. No idea if those jingles exist now - I did make a effort to watch the Christmas adverts, m&s, John Lewis, Tesco, bbc, Sainsbury's etc, on YouTube. I also make a conscious effort to look at movie trailers, and indeed let YouTube play past the first 5 seconds on trailers of films that I don't know about and look interesting.
By my own experience (19 countries, all continents) the poorer the society the closer relationships can get, and friendlier, in a heartbeat, as if social sympathy and being dependable is more important than being up on your own, because someday you may need some sort of help/assistance and cooperation pays off in the long term. In richer areas (even inside "poor" countries) this is exactly the opposite; people seem generally more independent in all regards so they come across as not that nice or as friendly as they could be.
Amazing people are naive enough to post this kind of stuff publicly!
Hmmmm.... I wonder if there's a way to do this with pythonista. It does have a share sheet module. Combine that with the base64 point below...
They can go pretty far with it. I've seen attorneys actually say "if you don't pay us, we will file a lawsuit detailing all of your illegal actions, and that will be a matter of public record that may open you up to other kinds of actions by various agencies". In that instance, the person being threatened filed a police report for extortion against the attorney involved, and...it went nowhere. So they can get their point across and the law seems to be OK with it.

There’s extremely limited compatibility with POSIX software, PASE exists but you aren’t just going to be porting applications with minimal or zero effort. Honestly IBM i makes little sense as a modern application platform, and DB2 for i is wonky plus licensing for it sucks (if you’re connecting from anything but Java where you can use open source drivers expect to pay through the node for DB2 Connect unless your application also runs on i).

I don't see how you get from these programs to something positive. So a woman in a wheelchair is shaken down by a low-paid security guard for $500 for a $2 purse she may or may not have tried to steal. The logical next step is for the security guard to shake her down for $50 to make the whole thing go away. Either way it's extortion, and it's the inevitable result of for-profit law enforcement (see civil asset forfeiture).

All I could think of when I read 'why would the government spy on the government' was the CIA director having to admit and apologize for the CIA hacking into the servers holding documents being reviewed by the Congressional committee investigating them for their torture program...
