Got interested, crunched some numbers.

A TBM costs like 10 million euros to buy, 5 million euros per month to operate. And move 50 feet a day. So, all combined it costs like 14 million dollars per mile to tunnel. But as in Mumbai's case (17 tbm for 33 km!), These are done in parallel for speed and to reduce costs, it's sound 30 million dollars per km. Which is almost the difference for mixed grade Delhi phase 4 and Mumbai's line 3 costs.

TLDR: tunnel boring costs 15 million dollars per km in material/operation costs, rest is probably rails+stations etc.

If that were true, I think we in the US wouldn't be hearing so much about the EU GDPR.

It's true.

That doesn't mean you can ignore other countries laws if you want to do business there.

The EU GDPR only applies to companies doing business in the EU. Of course, if you have customers in the EU you do business there under the GDPR definition.

You are free to ignore it. Good luck trying to do any other business in the EU after that though.
I think people are seeing the risks of people creating fake videos but there's another risk that I think is being overlooked. As convincing fake videos become a reality and articles like this inform the general public of that reality it becomes incredibly easy to dismiss any inconvenient videos as deep fakes. If Mitt Romney had made his 47% comment in the present climate he likely would have been able to skate by saying that was a deep fake, created by political adversaries.
I have written and erased at least 5 replies here. As nicely as possible, the approach you are taking is not a good way to be encouraging to bitter people. It feels on the receiving end very dismissive and like a kick in the teeth.

Για την ανατροπή η ΑΕΚ στο κύπελλο Ελλάδας
Turning 40 this year, so I remember the same media you do. As the Internet grew and options proliferated, I always wanted a particular kind of news that I haven't seen crop up yet. Just a feed. No commentary, no talking heads discussing what something might mean. Just a network which shows video of news events happening. If something is happening in the legislature, I want to watch the legislators doing it. I can get the interpretation and more information about what's going on somewhere else. But the bare "this is what happened" without the fluff just isn't something you can really get. And sure, there's still editorial influence in what they would choose to show and how its shown and other such things, but a countless number of times I've just wanted to see the thing that actually happened.

We have known for centuries that who says a thing cannot influence its truth. How a thing is expressed can't affect it either. An untreated schizophrenic hobo screaming into the street can be telling the truth, and an esteemed professor reporting on new findings in his field can be a liar. It has always been inadvisable to do anything other than analyze claims critically, and I suppose if deepfaking becomes widespread, that will have to be relied upon more than ever.
Unfortunately I just don't see this PSA as really having the wide reaching effect people want it to have. This is a classic case of a chilling effect. Unfortunately, most people are quite aware of what is possible, that when it becomes implemented, it is not newsworthy enough to grab their attention and spur action.
How would I go about creating a native image for a gem I've installed? I can't seem to find the documentation for this.

Or have I misunderstood this totally? I thought I could do something like ruby script -> graal ruby --> jvm bytecode --> native image

Update:: Doesn't look like I read it wrong - from this reddit comment[1] from 3months ago

Ahh, I think there's some confusion here. What we do with the SVM is ahead of time compile the TruffleRuby interpreter, not an application. This is akin to what you'd do with MRI. Instead of treating Java as a language you compile to a .class file and load with the JVM, the SVM's native image generator compiles it to a native binary.

There's likely no reason we couldn't compile Ruby applications into a static binary.

I would also love to be able to distribute a ruby binary as a single statically compiled executable. Any pointers/directions?

I think what you are describing is really how to learn. It's not that you require a test in order to remember material, you just need to implement what you have read in order to reinforce what you have read into memory. Humans remember things a lot better when you have an experience to associate with it.

I would argue the »also« is misplaced, that is really the only thing thing that the proof of work does.

Recently (a few days ago) interviewed at a small startup (20 ppl) for a backend position. All in all it went decently well. I reached out today to follow up in regards to a timeline for them to make their decision. I was told by the Operations Director that the CTO would call me in a few days with his/their decision.

Having never interviewed at a startup before, I'm not sure what the process looks like. However, I do know that for larger companies, HR usually makes the offer phone call - which has me thinking that the CTO won't be calling with good news in a few days.

Does anyone else have experience receiving a yes/no from a small, new company and care to offer some advice?
From the article:

> Our Lisp services are conceptually a classical AI application that operates on huge piles of knowledge created by linguists and researchers. It’s mostly a CPU-bound program, and is one of the biggest consumers of computing resources in our network.

CPU-intensive processing is exactly the kind of work that the BEAM is lousy at handling. Elixir would be a terrible implementation language for this kind of thing.
I file on paper, as I always have, because a) I absolutely refuse to pay money to file my taxes, and b) I especially refuse to pay money to companies that lobby for taxes to be more complicated.

There are free e-filing solutions, but not for my income range, and also last I checked (this might be a year or two out of date now) the various state-level agencies do not play well with the free e-filing.

And the paper forms are so easy! The hard part is sometimes figuring out whether you qualify for a particular thing or what a particular piece of income counts as, but that's more or less just as difficult even with software. Actually filling out the paperwork? Almost restful by comparison.

I cannot attest to the above suggestion that "CIABook" is installed, as I have not reviewed any of the Android source.

Instead, I offer different information: I know of a person who is switching back to a pager to avoid smart device-based tracking. This after he received the requested "all information Facebook has about me" and saw how many of the quizzes he took for fun were advertiser-based, articles that seemed to be interesting (and were not about products or services, per se) being brought to his attention by advertisers, as well as other behavior he thought was innocuous but instead resulted in yet more data gathered about him.

It is my understanding he is piecing together different services to allow the pager to still be able to communicate (eventually) via IM with the right hand-offs involving services who rank privacy/no-tracking towards the top of their service offering.

There is some interest among his peers to offer this as a service, for those who might find this idea desirable. Apparently there are refurbished pagers available for purchase that can be used in this way.

He has jokingly referred to it as a "Hi-Tech detox" process...

I also do SEO work for lawyers, primarily PI and mass torts type stuff. It does work - to an extent. There are certain technical things you need to get right and that alone can rank you decently, especially locally. There is low hanging fruit that can put you miles ahead of the competition and I've done this time and time again.

The problem with SEO and why I have a grudge against the industry is past success by gaming google with PBNs has led to hoisting up a few sites that can dominate because of their past. Those sites used spam tactics, then ranked high, that led to actual relevant backlinks, google got confused, and now keeps them at the top for any new content. Others must also utilize these dicey methods and pour serious money into it to do well. At least nationwide. I'm praying for the day that house of cards comes tumbling down.

Until then, having a better site, with better copy (done by a professional writer not farmed out), and using Adwords typically is the go-to.
I work in advertising (check my post history).

Likely this is just "household extension". How it works:

1. You visit my website on your phone
2. I can now send ads to your phone, but not your desktop
3. I enable cross-device targeting
4. I can now send ads to your phone, laptop, and work computer
5. I enable household extension
6. I can now send ads to any device associated with your household (your girlfriend's phone and laptop, your son's tablet, etc.)

The more likely explanation (for the kung fu stuff) is just random chance. You get like 500 ads a day, so some of those will coincidentally line up with things you've recently done.

But your behavior (watching a kung fu movie) might have gotten you or your household added to a 3rd party audience for interest in karate, and then you get karate ads. Same for open houses - there are data providers who sell the audience "user has been to an open house recently" or more likely just "in-market for real estate services"
This would let Google know these accounts are affiliated with the same person on your network, whereas containers won't necessarily provide that assumption.

Since the universe is 13.8 billion years old, we are able to see objects which are 13.8 billion light years away. How are the physicists able to say that the diameter is 93 billion light years? Shouldn't it be closer to 27.6 billion light years in diameter?
> Proof of work is the leader election phase of consensus.

This is a common misconception stemming from looking at PoW through the Paxos/RAFT prism. In Paxos a leader is elected, then the leader decides the order of events. But that's not a valid comparison, because in PoW the supposed "leader" does not get to decide anything at all - the block has to be put together prior to "winning the election" (because the block is the input to the SHA).

PoW is a radically different approach - there is no leader, but there exist indisputable points in "blockchain time", and the order of blocks is determined by the longest chain, which is essentially a matter of chance.

Another related misconception is that PoW is good, but proof-of-stake is better. In fact, PoW is the evolution of PoS, not the other way around. A PoS based digital money was described 1998 by Wei Dai [1], but that approach had flaws that would only be overcome by a system described Nakomoto's Bitcoin paper.

How to handle remote work red tape in the USA?
My company is expanding our 100% remote work model into the USA.

We currently employ dozens of developers and administration staff across Australia and New Zealand with a couple in the USA through our USA c-corp. But in the USA it seems we have to produce unique contracts / employee handbooks et al for every city and sometimes suburb in those cities to comply with local laws, as their place of work is their home office.

If employees never moved, this could be acceptable, but (rightly) they do.

How do USA companies (and I'm talking companies without dedicated legal teams) handle this massive compliance requirement? I haven't found a legal team yet who are savvy in this 100% remote work model and would appreciate any recommendations.
As I tried to explain, it's a matter of degree. If a comment contains both bait and substance, it falls to the rest of us not to take the bait, since doing that guarantees a useless tangent or worse. The acceptable options are either (1) react to the substance, or (2) don't react.

PlayerUnknown's Battlegrounds: From Pre-Alpha to 20M and Counting
For a 20 person startup, it seems normal that the CTO would review all hires. If you visualize it as a small classroom's worth of people, it's easy to guess that new hires are probably still impactful enough on the company as a whole to get attention from the execs. Maybe not every company does it at 20 employees, but I imagine many still do.
