I recently visited friend at his lab. I cannot say much but they work on patent for something he calls “pantone fiber”. Basically within one cable they are able to squeeze about 16,000 different shades of R/G/B “working” next to each other. When I grasp the idea it blew my mind - he looked at me and smiled saying - “yeah about 10,000 times faster than current fiber”. He said two things tho - one state of tech is not ready for such speeds and latency - unlesn you have 16K def TV. Second he said they wont release it until much more cable has been layed out. So that of course they can restart relaying new cable again and make more $ ;)

I've been trying to use CMake for a couple of years now, but I still feel like a complete beginner.

CMake makes it very difficult to do things right, and very easy to do things wrong. Even something simple like including a library becomes a nightmare if another library you depend on also includes the same library (such as Google test). The tool has so many sharp edges that I'm almost ready to go back to makefiles.
This is just throwing more (fossil fuel) energy into collecting and burning avoidable trash and into building more structures to accomodate it. How is that "top notch"? This might solve the short-term plastic pollution issue, but goes against all recommendations for climate change mitigation.

It's time to start considering CO2 emissions as our transparent, unmanageable trash. Each Singaporean is generating 10 tonnes of it yearly, and each American is generating 16 tonnes of it yearly.
Half-facetious. If a government really wants to hold on to power by force, they can do it one way or another - elections end up being theatre in that case anyways.
> Experimental group of mice received subcutaneous injections of the LD50 dose of (−)nicotine hydrogen tartrate of 3 mg/kg/day, 5 days per week for 24 months, and control group received the vehicle phosphate-buffered saline.

> ...

> The purpose of this pilot study was to evaluate the pathobiologic effects of long-term, high dose nicotine treatment of A/J mice susceptible to tobacco product-induced lung carcinogenesis.

These were mice genetically engineered for increased cancer susceptibility and also given insane dosages. This study is designed to answer whether nicotine is not carcinogenic. That is, if the result was negative then it would suggest any future study would be wasted effort. A positive result doesn't say anything about the safety of nicotine, per se; just that there remains the possibility it may be carcinogenic. That's very different as many absolutely benign substances could also produce this result.

Yelp bought food delivery service Eat24 for $134 million in 2015 and integrated it. They sold Eat24 to GrubHub in 2017 for $287 million and swapped for a GrubHub integration/partnership. As of 2018, DoorDash was still struggling to turn a profit.
High frequency traders create liquidity. Arbitrage in general helps ensure that prices are uniform across geographies and across linked securities (e.g. options are priced appropriately vs. the underlying asset). You can argue that there is no incremental value in going to shorter and shorter timescales, but fundamentally this mechanism is how information moves around the economy.
I'm sure that Marcono would like their answer as well.
When you use TypeScript with React (and want sound typings per policy so any type erasures/widenings are considered bad practice) Hooks are a big leap forward.

Typing classes was much to verbose, and the type system of TypeScript to this day is not a perfect fit to type class-based components. Hooks solve this problem - probably unintentionaly.

Example: With Hooks you almost never need to explicitly type the type of state of a component, as whatever you pass to useState() will auto-infer the type. While when using class-based Components, you'd have to specify the state type as a generic argument; you'd have to manually specify it when you set a state using this.setState() as partial types were allowed due to reacts auto-merging of the passed argument to the state. And you'd have to use some kind of Partial<State> type when assigning only some values of the state in the property constructor.

Similar issues exist when using the static defaultProps field in TypeScript - the type couldn't be inferred from the generic class argument, as a Partial<Props> type is valid for the defaultProps field. As a result, the defaultProps (as well as the default state property) is cast as the empty object type {} by default if you don't explicitly assign a type - which makes you lose basically all the type information because every object is assignable to {} in TS.

And if you ever tried to strictly type your HOCs or renderProps you know how hard it was, sometimes utilizing the conditional/mapped generic types feature of TS. This is completely gone with Hook.

I could go on telling how stupid it is when you disable nullable types in TS (strict mode) because TS will not let you use any non-nullable prop inside of render() - even if that prop is initialized in the static defaultProps field. You'd have to override the non-null check using TS exclamation point operator. This is also gone with Hooks.

I don't know if they designed the Hooks API with TS in mind or if this is completely accidental, but if you migrate a TS project with strict mode enabled to Hooks, you will see how much implicit type annotations can be dropped, and still retain strict type checks. Big fan of it.
I have to disagree that all changes in the details of product disbursement originate from an increased benefit to consumers (rather to to benefit producers as your comment implies), but I cant deny that there are substantial benefits on both sides once you ignore the externalities. Regardless, it is practically impossible to avoid buying most goods without at least a small amount of plastic packaging, so even if the masses were capable of organizing to effect change regarding packaging, someone has to recognize a market for it and change practices accordingly.
Why not using CMake/cpack? It can generate 100% valid Debian packages and you don't need to do a C++ project, but you can package whatever you want.

I wouldn't go as far as calling the Lauda Air anecdote "evidence of something", but there appears to have been a pattern whereby Boeing writes the rule book for test procedures, which are then adopted by the FAA as the standard. Of course, a manufacturer would not publish a set of tests, then promptly fail to pass them.

So the question becomes - assuming this dynamic is still valid today: what independent mechanism exists to ensure Boeing's standards are sufficient?

Just would like to offer a joke and a quote from the music world. The joke is, How many guitar players does it take to screw in a light bulb? And the answer is, 10: 1 to do it, and 9 to stand around saying how they could've done it better.

The quote is from Ian MacKaye: "The best records are the ones that get made."
Arguably, the reason why the valley was the best place for startups is due to the density of the VC economy there and the wisdom of founders who have exited startups there. Once other factors have provided enough competing negative value the only thing that is left is empty consensus (trend chasers, vanity, popularity admirers), which is healthy for marketing but is horrid for innovation.

With those things in mind if you have no problem achieving early investment and a healthy base of users/clients there is no reason to be in the valley (or any high cost market).

I teach people that there are many ways to encode numbers into 0, 1 symbols (state of switches). One obvious way for natural numbers is base-2 (with more significant bits on the left). It get's more complicated with negative numbers (two's complement usually, but could also be one sign bit). Floating point numbers are hard. You could also use variable length integers where small numbers are represented with less bits and you use one bit to mark end of a number (every 8 bits).
What I find fascinating is that they also have many repeaters given the massive distances covered by these cables so they need to provide electricity through the cables on such long distances.

Name the way to create incentives that doesn't involve money then. Many have tried, non is successful.

Pricing, supply, demand, are ways consumers indicate their interest in products and services, and recycling is very low value, because nobody cares.
>So if there's nothing holding technology to SF/LA

You just stated the reason why the tech companies are there. Feedback loops are a real thing that happens.

As a result of all the tech companies being there, the tech VCs are there, the recruitment agencies are there, etc, etc. That’s just how this works. To see the original factors you’d need to look at the history of the region, but beyond a certain point these things become self sustaining.

Sure there are forces in the other direction, and some individuals or companies might find them compelling, but specialisation works.

There are no advertisters paying for anything, and yet the content exists and is available.

If there was such a thing as "free" content on the web then this page seems to represent that idea better than the pages of today.

While today's pages may be more technically impressive by showcasing browser "features", they also pose more potential risk to users on several fronts. There is a cost.
Fun list, but it is pretty impossible to compare riches across history. Augustus personally owned Egypt, the breadbasket of the Mediterranean at that time. How to you even assign a dollar amount on that? How do you compare the purchasing power over time, when some valuables like gold or salt have become much more abundant, and other things like slaves cannot legally be traded anymore?
You're going to want to let people use their own certs if you want to sell to financial institutions and the like

And wildcard certificates imply sharing a private key around which is terrible advice

If you're a business spend the money on certificates, if the business pushes back ask them "how much is your data worth? How much will reputational harm cost us?"

Lots of people suggest rolling your own CA but I bet most of the internal CAs out there are terribly secured and not audited.
This is just plain wrong. Did you even read the article?
> Tobacco may well be as addictive as heroin, crack, alcohol, and Cherry Garcia combined into one giant crazy sundae. But as laboratory scientists know, getting mice or other animals hooked on nicotine all by its lonesome is dauntingly difficult. As a 2007 paper in the journal Neuropharmacology put it, “Tobacco use has one of the highest rates of addiction of any abused drug. Paradoxically, in animal models, nicotine appears to be a weak reinforcer.”

> That same study, like many others, found that other ingredients in tobacco smoke are necessary to amp up nicotine’s addictiveness. Those other chemical ingredients things like acetaldehyde, anabasine, nornicotine, anatabine, cotinine, and myosmine—help to keep people hooked on tobacco. On its own, nicotine isn’t enough.

https://www.scientificamerican.com/article/will-a-nicotine-p...

There are other sources and studies I'm too lazy to look up, but AFAIU nicotine is a powerful cognitive enhancer that makes activities easier to perform and more rewarding (including, perhaps, the metabolization of other substances), and it's this experience boost that may be what addicts people. In any event, it's now understood--relatively uncontroversially--that this is why many people with certain cognitive deficits (ADHD, schizophrenia, depression, etc) self-medicate with nicotine, though it works to elevate cognitive performance even for people without deficits.

Yeah, UPS trucks don't make left turns. Maybe self driving cars can do the same.
It's the only option because it's the best option. Without plastic what would you package things with? Everything is shit by comparison.
Can't decide whether this is an unprecedented display of lack of professionalism or a trick to get people to purchase more cars nearing the end of the quarter (because they are dangling the "prices will go up" sign in front of buyers).
Exactly, it's "shocking". I guess that's why the pilots reacted the way they did - they didn't expect the stall & it was probably shocking for them, especially if they weren't properly trained for it or thinking that a stall is impossible or takes "much more effort than this".

There's also been quite a few of these type of stalls documented in the past (eg. where the pitot tubes failed).

I've rented some of these lines as part of a financial trading infrastructure.

What's immediately obvious is the line is much faster than going over the public internet, and there's no jitter: every time you ping it comes back in the same amount of time, whereas the internet pings will vary by several ms.

You also become acutely aware of cable breaks. Somehow this happens quite often under the English Channel. The network operator will start sending you emails that say

- Cable break detected

- Loading ship (can take ages)

- Found the break

- Patched it

- Back up

Occasionally bad weather would delay it.

BTW truly random numbers can not be used for live communications encryption as they can not be reproduced by the recipient UNLESS they have a EXACT replica of the random numbers or its audio image in a recording (See: American SIGSALY machine during WW2). However pseudo-random numbers can be reproduced live by the recipient via prearrangement but not easily by an outsider (See: German ENIGMA machine also WW2 vintage).

POTUS Thomas Jefferson invented a really amazing encryption machine in 18th century using a quasi-pseudo-random arrangement which utilized the ancient encryption art of Steganography. (See: Jefferson Wheel Cypher). It helped us beat the Brits here in USA and abroad. :P

Banning vaping outright seems ridiculous but there need to be more aggressive policies and enforcement on the sale to children. The FDA did a study and I remember the numbers being staggering (2/3 teens I think) have vaped before. A high number of people using addictive substance before 19 is a recipe for disaster regardless of the compound since lifetime addiction rates soar at that age.

This is so neat! Few questions though, if anyone can answer:

1) The cable still looks pretty thin, is it being housed in some sort of protective layer/tube before it is laid? Seems like an anchor snag could easily break that line. If that happens, is it possible to 'patch' a fiber cable?

2) Once it nears the coast, how deep is the line being buried?

3) This may be a dumb question (I'm no engineer), but does the light travel from the source all the way to end without any "relay" mechanism?

4) How much bandwidth can travel through one of these lines?
Which way does the blob point
My take is that that there is no way to prove conclusively the existence nor the nonexistence of an afterlife. So each person makes a decision (bet). At the end of this life, we each find out if we were right or not. Well, technically, if there is an after life, we would find that out. If not, we don't find anything out, do we?
TypeScript already supports those 'class properties' - and with a few extra features - so you don't need to use Babel for this syntax: you already have it.

As I recall one of the problems with the Concorde was that the existing fleet was getting quite old and spare parts were hard, if not impossible to come by.

The incident in Paris may have sped up the process of decomissioning the plane, but it would have happened anyway eventually.

All was not lost. A lot of the more visionary aspects of that plane, were implented into later Airbus models (i.e. the glass cockpit derives directly from the Concorde).

That's exactly what I was thinking as well. And what's more, it seems like they are laying more new cables than what "public" infrastructure is, going forward.

That can literally mean GooFaceAma has better global performance than competitors. Or that competitors will be forced to get hosted on one of those cloud providers to get similar performance.

It makes me feel a bit worried that "the internet" is not as neutral as I would like it to be. (Or that I thought it was before)

I think, you are romanticizing a very painful aspect of life, to which there are no clear answers. As some where later in the thread, your argument is more about assigning virtue to need(because of not enough options).

Another place you mention daughter-in-law caring for the elders. Totally ignoring the sexist nature of that proposition. Also in reality that whole in-laws under the same roof, has its own set of complications. Often resulting in a very unhealthy dynamic. When children also get affected in the politics of the grown ups.

I think, this is a very complicated and painful problem. For that no universally good solution exists. Its a problem worth solving though, anywhere in the world.
