Could some knowledgable aircraft people answer these questions for me?

1. Can/are jet engines ever swapped out after a plane as been put into service? Or will these only ever be sold attached to new aircraft orders.

2. Any idea on what the engine costs? And what percentage of the overall airline cost is engine? I didn't see any references to costs of this engine vs existing models.

FTA: "backscatter technology, previously deployed in European Union airports, was banned in 2011, because of health concerns; an internal presentation from American Science and Engineering, Inc., the company that manufactures the vans, determined that the vans deliver a radiation dose 40 percent larger than delivered by a backscatter airport scanner; bystanders present when the van is in use are exposed to the radiation that the van emits… moreover, petitioner maintains, and it is not disputed by the NYPD, that ‘there may be significant health risks associated with the use of backscatter x-ray devices as these machines use ionizing radiation, a type of radiation long known to mutate DNA and cause cancer."

Not only are the fascists surveilling us invasively, they're giving us cancer via a well-understood dose of ionizing radiation. Oh, and the commissioner refuses to think that we should know about any of it.

Really? I don't find them challenging at all. Would be even nicer is they put a protected bike ring around the outer edge so cyclists only have to watch out for the part they are crossing across.
I'm in SF and Amazon packages use Ontrac. Ontrac appears to use contractors that just have a sticker on the side of their car with the logo. In the last month alone I've had them forge multiple signatures + report a package as delivered when I've been home all day and nothing arrived. And other times they throw it a decent distance or put it in front and it's stolen within five minutes.

Amazon re-ships via UPS/other and it arrives acceptably. The worst UPS has done is not knock/ring and that's rare.

90%+ of my packages via Ontrac had forged signatures, misreported delivery statuses, not actually arriving, [...]

I use OpenShift and I think it's fantastic. You can even install your own SSL cert on the free tier (if you register their "Bronze" level, IIRC) for no additional charge. It's perfect for a hobbyist project and then scaling it up if necessary.

Also, once I started accumulating projects on Heroku, I appreciated the consistency across maintaining, managing, and deploying those projects.

Meanwhile every time I'd deploy a new project to Linode, I'd use a different deploy script/strategy as I'd learn slightly better ways of doing it. It's much more annoying to do maintenance on my Linode projects I haven't touched in 6+ months, and it turns out I usually don't have the energy to re-credentialize in the idiosyncrasies of each sideproject, so they languish.

I've been playing since mid alpha.

Yeah, it's pretty good! It's at least fun for a little while. It's an interesting series of puzzles to build an efficient system, and the flavor of the game is fantastic - every now and then you sit back and think a bit about prisons in general.

But for the most part, it goes for gonzo silliness. Which is a good thing! It's a game, and it's mostly pretty fun.

I'd recommend it. I think you'd probably play it about 15 or 20 hours and then wouldn't touch it for a while.
Thanks, very nice, bookmarked as usual at https://community.kde.org/Kexi/Links#Competition
Irrelevant to what? The poster claimed that there was a real thing in a physical reality. If that is true, shouldn't we have observed it before? As the statement stands it claims as absolute reality something which no one has ever seen.

Doesn't the fact you can get the attention at will disprove your hypothesis? It's the behaviour that gets the attention, otherwise you wouldn't be in control. If it weren't the behaviour then you'd get approached as often when you don't do as when you do.

As I said before it could be that you get observed more because of your demographic, but if you can perform a behaviour that gets direct attention then it's not your race or other aspects of your appearance that's causing the staff action.

Just stand where you are and start swearing loudly will work too, you'll get a member of staff, they'll say "can I help you" - it's the usual attempt in a commercial environment to be non-confrontational when really one means "you look suspicious, why are you here" - you then say "please ring this up for me". Chances are they see that will get you out of the store ASAP, which would be their intention during the approach.

I work in a store, it's really obvious when people don't follow standard purchasing/enquiry patterns.
It's a bit like how all the casinos in Vegas are owned by something like 3 companies, or how all the detergents are owned by Unilever.
> The US system is still pretty bad. Banking throughout Europe works a bit differently everywhere, but the basis is that you have wire transfer for basically free (inside the Eurozone, this covers the whole Eurozone). Paying rent? Just set up a monthly wire transfer.

The reason this came to be is that the Eurozone sets up a more beneficial system for the banks than the status quo. Barriers to international transfers hurt both small and large banks, and having many sets of laws and politics around the rules made them exceedingly difficult to change. The Eurozone fixes this.

In the US, interbank transfers are regulated by the banks themselves (NACHA) and the majority are performed in partnership with the Federal Reserve. The banks have all the power to improve payment and transfer systems, and none of the impetus. We have been stuck on a 40-year-old daily batch-file processing system because the banks make too much money on wire fees.

It took threatened action by the Fed and Congress for NACHA to finally make same-day transfers mandatory for 2016. Note that this is still not a real-time system, and we are very, very far from such.

> "Pull" also works and is common in many european countries through direct debit. You give amazon/your electricity provider/whomever your bank account number and they just pull the money from you. No sketchy credit card companies needed, fraud is pretty minuscule.

This is how ACH pull works in the United States. It is enticing because the ACH network is very low-cost and the credit card networks are not involved. And yet it is a consistent source of fraudulent activity. There is nothing inherent in a "pull" model that prevents fraud; you need additional controls around the relationship to prevent that.
The worst is that in some places - like Chicago - Al Capone arguably had more political power than the legitimately elected government.

US transportation secretary announces drone registration requirement
Yes, they're placed into a duct/shell and can be removed and replaced because the engines have a set number of hours they can run. Also if newer engines are developed they can be swapped (Thanks for /r/justrolledintotheshop) - I recall the cost to replace around $16 million, don't hold me to that though.
It's been a while - patents are designed to expire, and in this area they sometimes actually do.
I suspect that we will see porn take advantage of these new technologies (in fact, I have seen internet controlled vibes). However, I doubt that the quality will be substantially higher.

The one way I can see this technology leading to higher quality is by centralizing capital in a much smaller number of producers, who then have the resources to produce higher quality porn. However, they also would have much more of a monopoly, so I am not sure how well this will work out; and eventually production of new style porn will become more democratized.

The bigger change we need to make is social/economic. Porn simply does not have the monitization avenues that film does. Mainstream advertisers don't want to touch it, and consumers are reluctant to pay for it. This puts us in a situation where, as the author describes, most porn is itself produced as an ad for other sex services.
Wow, that's a great datapoint.

Can confirm - I've been using Hetzner for over 2 years now with no problems. I serve quite a large amount of traffic on an EX40 (it was costing me a fortune when I was with AWS).

Although a company I worked for had a Hetzner server where 3 out 4 of the hard disks failed. So it might be wise to do regular backups off-site.
gofmt works freaking beautifully for this though. Sure, if I tried to do it myself, I'd screw it up. That's why I don't do things that the computer can do better, easier, faster then I can. I just hit save, and my editor routes it through gofmt and refreshes file. It's to the point where I'll hit ctrl-s after moving a brace just to have gofmt reformat, CAUSE IT DOES IT FASTER THEN I COULD.
Generics can be nice, but they're clearly not "necessary" to any of the languages that don't support them. Besides, the cost that generics would exact in terms of syntax complexity, compile time, and startup time is something that many Go-detractors dismiss as irrelevant.

Myself, I think enforced tab-based formatting is utterly insane, but ultimately it doesn't matter. Part of the philosophy behind Go is to keep certain things very simple, and leaving generics out is a big part of that. I don't think that they're going to change their mind because non-Go programmers advocate for them. If that makes it the wrong language for your project, then there are so many others to consider.
You should be able to do that just fine. 'dir d:' runs on the windows box and 'less' on the unix box.
Secure multiplexing, VM's, and kernels were repeatedly done back in 80's and 90's under the Computer Security Initiative. See p5 on this one for an example where trusted functions efficiently did I/O multiplexing requests (syscalls) from untrusted drivers in guest OS's:

Intermediate emacs user here. I really like the way Atom highlights Python code. With this I see it being even better. A question for the author: does this expand upon the capabilities of the editor or just provide a route for quicker updates that eventually could be mainlined?

I've been thinking about scratching the itch to expand emacs Python highlighting to match that of Atom. From the looks of it, the code highlighting was primarily regex based, and the same from my cursory observations looking at emacs Python-mode syntax highlighting mechanisms. Could I incorporate this somehow into emacs from what I've said here so far?

Also, thanks for helping out the community!
When I was 16, I've been given a book which summarized the addiction power of many drugs. Here are those I remember:

LSD: 1 star (if I remember correctly)

Canabis: 1 star

Cigarets: 2 stars (notice how people have a hard time to stop smoking)

Alcohol: 3 stars

Cocaine: 3 stars

Heroin: 6 stars

In my mind, if you try heroin once, you're addicted. Is that close to be correct? Because if it's correct, then the less people try it, the less there's addicts.
It also pushes addicts outside the protection of the law, making them easy victims for other crimes. They won't seek the protections of the criminal justice system because they perceive themselves as being on the wrong side of it and likely to be as abused by the system as they were by their victimizers.
And if they are simply watching - do you think leaving the audience with an empowering undertone leaves an inherent 'promo' undertone as opposed to other documentary style that is more critical, fact finding in essence?
You can't have it both ways if you are the government... it should be the same for everyone.

Uncle Ho was prepared to throw any number of people under the bus for a unified Vietnam. Our senior command just didn't understand this or couldn't deal with it.

Estimates are a million Vietnamese died between 1950 and 1975.

And you understand that the entire plot of "Apocolypse Now" ( which was fiction ) was that Kurtz was prepared to use any means to win, and that this is why he was targeted for assassination? "His methods were... unsound."

This led to the Powell Doctrine. In the early-90s Gulf War I, the objective was actually met, although the resulting equilibrium was not stable.

You're right: it was proven with the invention of object-based, disk storage that kept things simple. Think NoSQL key-value stores vs common SQL databases in performance. Eliminating complexity in the underlying mechanism while allowing the app to decide how it's used can certainly benefit performance.
> Only a barrier method can be completely effective (and even that fails).

I would not call it completely effective. Someone who uses a condom perfectly, each time, every time, still has a 50% lifetime (35 year) chance of having a child.

And with more typical use a person is all but guaranteed to have at least one child during their life.

Condoms help reduce fertility (i.e. smaller family size), they do not eliminate the possibility of children.

Someone who absolutely does not want children does not really have any good solutions except avoidance. The typical advice is two methods of birth control at once (i.e. hormone plus barrier), but that's only an option for females.

How to Blog While You Build the Product (a 6 Step Process + Workflow)
You're exactly right. But as you suspect, there's reasons why you wouldn't want to do that in all cases.

Turbojets derive all of their thrust from the turbine exhaust. It's a small, compact engine, which means high power-to-weight ratio, and it's great for small jet fighters. Unfortunately, it also consumes a lot of fuel. Turboprops are at the other end, where the turbine drives the propeller at much faster speeds than a regular 4-stroke engine would. But the exhaust provides next to no thrust.

Turbofans sit in the middle. They provided much better fuel efficiency than a turbojet but greater power than a turbofan. It was very much a "we need a middle solution" type of engine.

As turbines became more efficient and compact, the turbofan became smaller as well. To the point that they could be places on a fighter, but with a smaller bypass ratio. This gives much better fuel efficiency (range), while still retaining high power.

For jetliners, it's all about efficiency, but still retaining a degree of speed. But for a really high-bypass turbofan (50% or more), it's going to be a huge engine. Fighters are between 15-20% now, but you won't see much more than that.

Slightly different, under Use of Invalid Carriages on Highways Regulations 1988 http://www.legislation.gov.uk/uksi/1988/2268/made, S 10(1)(a) a class 3 vehicle - those with a speed limit above 4mph (which are allowed to go 8mph on roads) - must have "a device which is capable of limiting the maximum speed of the invalid carriage to 4 miles per hour". They are also required to have an indicator, which they must by the same law be able to see when using the vehicle, which shows if the limiter is in operation.

It seems a bit harder to sell than speeding a few mph above the limit in a car; but in either case those that want to flout the law are able to, you are right.

Analyse Asia 68: Little Rice with Clay Shirky
Prohibition might reduce the total number of people who have ever tried a drug, but I very highly doubt it reduces the number of people addicted to a drug. It could just as easily increase the number of addicts.
Synopsis: Within the great firewall of China, Clay Shirky, associate professor from interactive media & arts department in NYU Shanghai and also TED speaker, joined us to discuss his latest book “Little Rice – Xiaomi, Smartphones & the Chinese Dream”. In this episode, he shared his thoughts about the revolution of different media platforms and its after-effects to the evolution of Chinese companies from hardware manufacturing to software services and how the continued tension between economic development and political control will change the nature of Chinese companies going global. We also discussed how Xiaomi embodies “the Chinese Dream” and the challenges that it will face in expanding globally to the world.
Because of safety. For a brand new concept engine, you don't want to have any doubts at all. That means lots of long term testing. Since it will be powering jetliners, it has to be as close to flawless as possible. And even then, they have to convince the airline companies to use it.
