STOBAR[1] carriers like the Kuznetsov are vastly less capable than CATOBAR[2] carriers, they're the budget option. Using a ramp rather than a catapult means that the types of aircraft you can operate are more limited and the weapons and fuel loads they can actually get into the air with are significantly reduced.

As for the new systems in the Ford class. The EMALS system replaces conventional steam powered catapults because it can be more finely tuned to individual aircraft types. This means less stress on airframes which translates to longer operational lifespans. It also allows for easier launching of a wider variety of aircraft weights.

In the case of both the catapult and the elevators, the new systems are mechanically much simpler than the old ones leading to reduced operating costs.

All of the changes mentioned exist for a good reason, the issue is that they weren't implemented competently.

This is actually quite straightforward after being referred as the vector method call (basically map) and the other stuff is just function/operator calls apart from maybe the :by{.chars} which I can assume what it's doing but only after seeing the implementation I can see that it's something like a named parameter with a lambda

Reading these articles by Damian I almost get jealous of how expressive Perl 6 is.
And yet somehow Linux manages to run on a greater variety of hardware than Windows does.

I am of course including supercomputers, embedded hardware, and hand-held phones. Admittedly Windows has greater support for is running consumer hardware for desktops. But that has to do with how small the Linux marketshare is. And is hardly an indictment of Linus' work.

Just try copying video between different containers (mkv, ts, avi for one) without reencoding.

> Most users use x264 _via_ ffmpeg since they may need to filter the video and/or filter/process/mux audio and other streams.

They don't have to do that; you can handle each track separately and mux them back afterward.

I'm talking about ffmpeg's builtin MPEG2/4/MP3 encoders, which nobody used when they were competitive because it leaves all the options at "go fast" instead of providing tunings.

They're also unmaintained and the code is hard to figure out - that's why x264 was a separate project instead of just another part of libavcodec.
I imagine that's one thing that sonar technology does guarantee. They'll have exquisitely-detailed acoustical profiles for everything in the water that's bigger than a tuna.

Yes, it does. Which means that for about 30 years it did not, and a lot of Emacs software still uses dynamic scoping.
Rachleff says:

“Because people, human beings, by their nature, are risk-averse. If I hear that you didn't build the product for me and that you did it accidentally, I'm going to have less confidence that buying your product is the right thing to do. Look how Apple revised history of the iPod and the iPhone. They said they were Steve Jobs's inventions. They weren't. He had nothing to do with them. The Apple marketing machine made you believe it, because it made you feel better about buying them. The true creator of the iPod was a guy named Tony Fadell, who went on to start Nest as well. He recognized the value of iTunes. There were a lot of MP3 players back then, but he realized that iTunes on the Mac, where you could rip your songs, was the ideal tool to deliver a better digital music experience, and that syncing to iTunes was the key. That's what he pitched Jobs on, and Jobs funded him to do it, like a venture capitalist. That's not the story that was told.”

I’m curious if that’s the complete story. Is there more to this?

For me, being able to iMessage / AirDrop / Facetime people is worth the money just from a people standpoint. Apple has a lot of vendor lock-in, and they still have the most polished product by far.

why did you only quote that part of the paragraph? here's the rest:

> Torpedoes are not that much faster than their targets. The Yu-6 is capable of 65 kts in attack mode, but the range figure is for cruise mode, which doesn’t have an associated speed. Even a 65 kt torpedo is only about twice as fast as a carrier, and the sound of the torpedo being fired is enough to alert any ship with a live sonar operator.7 This means that the target ship is likely to be running away, and the submarine has to close to within half of the effective range before launch. Furthermore, the target and its escorts are likely to counterattack, forcing the submarine to evade and cut the torpedo’s wires. A torpedo has limited space for sonar, and without guidance updates from the launching submarine, it can be evaded. All of this is likely to limit submarines to launch ranges of 8 nm or less.

he's saying that the effective range for the torpedo is much shorter for a moving target, forcing the sub to get dangerously close. then after being detected, the sub would have to disengage and stop guiding the torpedo, at which point it could possibly be evaded.

If I'm watching Netflix, I am fine with autoplay. Youtube too, while we're at it. I.e. if I'm there specifically to watch videos, and you want to autoplay the next video after I'm done, that's fine.

What I'm not fine with is places that autoplay that have no business doing it, especially if they do that specifically to brag about how many autoplays it has (i.e. CNN). CNN in particular is my main annoyance, as when I go there I just want to read their news article, NOT watch video, and yet I have to scramble to hit the pause button on their video the moment I launch one of their pages (even by accident, because I'm just clicking a google link or a Hacker News link).

So long story short; Netflix and Youtube or sites that are just about serving video (and nothing else), autoplay to the next video is fine and expected. EVERYTHING ELSE, DON'T AUTOPLAY.

I've been following Julia for many years now and it hasn't quite picked up outside the Data Science/Research communities. I'm at a loss to understand why it hasn't gone mainstream. Technically, isn't this a superior language to everything out there if you are getting performance + readability?

To start the discussion, maybe one factor could be the lack of a package manager like npm/crate. What else?
iPhones have become extremely expensive so I buy a new one less often. I presume they set the price at the level that makes them the most money though.
Does anyone here have experience using submodules to tie individual repositories together? We've been using this in our small startup (only a few developers) and so far it works nicely. It allows us to check out and develop repositories individually but at the same time maintain an exact dependency graph for our entire system. You can for example have a single repository that ties together different projects and has submodules that contain specific references e.g. to the frontend, backend and deployment repositories. You can then use this master repository e.g. for deployment and integration testing. Gitlab makes CI/CD in such a setup very easy and checks out submodules recursively during a build, even across groups.

The drawback is that not many people are familiar with submodules and they can be a bit tedious to set up, though working with a submodule is almost like working with a normal file in git. One danger is of course that branching between individual submodules can get messy. Another nuisance might be that you have to commit recursively, i.e. if you have one repository with a submodule to which you make changes you need to first commit these changes in the submodule and then create a new commit in the parent repository that adds the new version of the submodule. Maybe this is a good thing though as it forces you to commit changes individually in each submodule before committing a larger change into your main repository. In general I would avoid nesting submodules more than two levels deep, as this can quickly get confusing.

In the past I've also worked on a large mono-repositoriy and enjoyed it as well, just curious to hear if anybody has used submodules in a larger team.
Close to zero.
The focus on privacy is not at all debatable compared to Android. There’s no way to argue that any Android device sold with Google Play Services (i.e. all of them in the US) is more private than an iPhone. iOS security and privacy is flawed in more than one way, but is infinitely better than Android.
Hey all,

Apart from Apple Music and iCloud storage space what services does Apple offer / sell?
You're touching on something unspoken but very present in the modern US military machine. It's great for wrecking anyone who isn't on the short list of China, Russia, the EU, Japan and maybe India. Every other nation could see their infrastructure and military devastated within a month, with little they could do to stop it. (See Libya for one example.)

But the American people aren't being sold a military that can act as the international equivalent of mafia leg-breakers. We're told, again and again, that we are paying for a military that is "the best" and that can, if needed, stand up to our global peers and near-peers and win. There's a disconnect between rhetoric and expenditures on the one hand, and demonstrated performance, capabilities, and operational plans on the other hand.

That seems like a huge problem to me. At the least, it's a massive fraud being perpetrated on the American public. And at worst, it might lead to a terrible conflict as decision-makers operate with very inaccurate assessments of what our military is really capable of.

Why did you only quote that part of the paragraph?

Because that's where it got seriously dumb.
You make your own social circle and only you can choose who you spend time with. If you are someone open about sexuality, then chances are that you will surround yourself with people who find this natural.

I absolutely reject the normalization of puritan values you are pushing. There is nothing abnormal and unusual at all about being learned about human sexuality and discussing the subject with friends. Yes, it can be something that does not attract you. You cannot, however, make such claims and present them as facts.

Being open about sexuality does not mean that you are socially awkward. Of course you need to read the room first. I would never assault someone with facts about sexuality and find it extremely distasteful when someone does so myself. You can be open about your sexuality while staying polite and professional. Being socially revolting is a character trait and has nothing to do with sexuality.

For example, I would never talk about sexual encounters with anyone from my office. I will, however, demystify and explain the details of sexuality and kinks if I hear people spreading stereotypes.

Talking with your close social circle at a bar or a house-party is not the same game as talking with co-workers or strangers. Nor is talking about your personal sex life the same thing as discussing the subject of human sexuality.

I have been talking about sexuality a lot in this thread and I strongly doubt that I have been revolting or distasteful about it.

But the Navy is under-equipped for its mission.

There are huge shortages of skilled (and less-skilled) personnel, because nobody in their right mind, in 2019, wants to enlist into active service.

There are huge shortages of particular kinds of supplies/replacement parts/training time/maintenance time.

Either the mission needs to be scaled down, or the budget needs to be scaled up. Pick one.
People are gonna say "how hard is it to send a marine down there with a grease gun" or "how hard is it to R&R a major system every 20yr"

Wartime operations beat the shit out of things. Stopping a system so some marine with a grease gun can do preventive maintenance is a low priority and gets skipped when you have to go from bombing dirt farmers one day to fighting a peer the next. Systems like this is what you get when you're expected to be running a decade long low intensity conflict yet still be ready for a peer adversary.

A large amount of the early US space program relied on "liberated" German technology and staff, from Von Braun downwards. Infiltration of Airbus is ongoing. The only thing preventing the US from "stealing" more is its own technological lead, not some innate moral superiority.

Apple still has a better product for people concerned about privacy and security. Not perfect, but better. They also have retail stores all over the place where you can get help when you need it. Again, the experience might not be great, but at least you have that option.

In the Android world, I don't think I would recommend anything but a Pixel device just because they get all the security updates and get them faster than Samsung and all the rest.

For the record, my phone is a Pixel 2.

The bigger differentiator though is the app stores. If there's an iOS app or Android app that you need, then the decision is made for you.

Ask HN: How do you improve your creativity?
It feels like for the last year or two I've been on 'autopilot' in my professional life, which is not to say I am coasting at work but rather I feel the creative spark in me has died down. Recently I've been making a conscious effort to change this through shifting from a consumption to production mindset (i.e. stop mindlessly browsing for hours) in my downtime but this has been difficult without some kind of short term goal or project to work on, frustrated by the problem that I feel my creativeness is at an all time low.

I'm looking for advice on steps I can take to improve my situation. I've just read Paul Graham's essay on "How to get startup ideas" [0] which had some pretty interesting takeaway points. I would be interested in hearing of other essays, books, tips, opinions or techniques from the community.

Robert Zubrin figured out a plausible plan to put a colony on Mars, yet the article fails to mention Zubrin and his Mars (Semi-)Direct plans.

Colonizing Mars with a small team of experts is possible and within our technological and financial means to do so within a decade or so.

However, the interesting question to me is not "can/how can Mars be colonized" but rather why would people move to Mars in the first place.

"Freedom from Earthly oppression (perceived or imaginary)" cannot work as an argument: a Mars colony will basically have to be run like a prison with 1984-level surveillance. A single crazy person blowing up airlocks or sabotaging the water or food supply can deal a death blow to the whole colony, and the cost to rebuild/repopulate will be tremendous, therefore the entire investment will be watched very closely.

Secondly, the monetary cost of moving to Mars will be huge and will be even beyond the means of Earth multi-millionaires, reducing the number of possible colonists. Also, because of the extremely high cost of getting anything to Mars and a lack of native manufacturing, there can not be a co-operative ownership of Martian infrastructure, so in practise everything will be owned by some entity (corporation/government) operating from Earth.

These points might change and "freedom from Earthly oppression" might become a driver once the colonists become self-sufficient enough to build self-sustaining underground dwellings with locally produced tools.

Therefore I think a succesful colonization must have two things: firstly, some kind of business force to fuel the flow of colonists, and secondly colonists who are not idealists looking for a frontier world freedom utopia, since it will not be such, at least in the beginning.

As for the business force, I don't know what this could be, maybe mining or manufacturing or such.

So I don't think the colonization is gated by things like lack of gravity, surface radiation, or impossibility of terraforming, etc. The lack of a plausible business model which could profit from having people live on Mars is the main gating factor.
