Iranian patrol boats always had anti-shipping missiles. They don't have many patrol boats, though, and they don't have many missiles. Beyond that, if you're going to use a missile there's no point in putting it on a boat if your target is in the Straight of Hormuz. You just launch it from land.

The concern is the Iranians (or whoever) would use speedboats packed with explosives and ram them into US ships. Speedboats and explosives are cheap, so this is a pretty easy attack to put together, and if it's a sneak attack you could get closer by having them pretend to be ordinary civilian traffic.

But the attack is pretty easy to counter, too - the Navy issued .50 cal machine guns with a mount that clips on the rails. The M-2 has a range of almost two kilometers and will turn a speedboat into kindling in just a few seconds.

Beyond that, people (particularly Dolan, who thinks everybody not him is an idiot) who point to that particular exercise have a fundamental misunderstanding of the way these things work. You can't get that many people and ships together doing whatever they want and not have casualties. The Navy did stop the exercise, and while they're not talking the most likely reason is the red team wasn't following the rules. The point of these kind of exercises isn't to develop new and innovative tactics - the point is to make sure everybody does what they're supposed to do.

Surely from my comments you saw me reference the long history of people complaining about poor parent participation, and quoted from a letter to the editor complaining about the teaching environment.

Therefore I can't see why you think I assume it's only about the curriculum.

Nor do I see how unions are relevant. Your 1960's classroom, in the cartoon that resonates so strongly with you, was almost certainly run by a union teacher, in a time when unions were much more powerful than now.

You can't decide to choose one part of history and not the other.

Because a couple decades ago Java convinced Enterprise Land that they can't hire millions of C++ jockeys and expect them to work effectively in huge projects that plan to evolve into the next decades' (aka: the present's) legacy mudball. Instead, they decided it would be easier to hire millions of Java jockeys and have them build enormous kiln-fired mudballs using the same architectural strategy as the Egyptian pyramids. They convinced academia to raise an entire generation of Java jockeys, hired them all right out of school, and set them immediately to piling up enormous mud bricks forever.

So, now they have a few million Java jockeys churning away and a few million person-decades of work put into their mud piles. When starting any new project, there isn't much question about how to build it: More Mud!

I keep seeing this argument all the time. Lets put a counter-argument-by-authority: Fran Allen [1] thinks that the C was a huge step backwards in language design [2], and there is no reason to think that Go didn't repeat the same pattern.

Interestingly, the article you quoted mentions functional programming and immutable data as the step to go from 200K to 2M lines. Go is fundamentally incapable of functional programming* and its builtins allow pervasive mutable state.

* Its impossible to support FP without generics. Even the most basic higher order functions require type variables.
Journalism is a high-prestige field which, to re-use Michael Creighton's observation, we understand is virtually never right about even the simplest consequential facts about things we actually understand, but we trust it to be accurate with regards to consequential facts about other fields, and this trust endures through every report that we have about journalists being catastrophically wrong.

There is some threshold of evidence that causes us to accept the BuzzFeed hypothesis, right? Right? God help me, I know I sound crazy, but I think I'm there.

Welcome to the ranks of conspiracy theorists. Anyone willing to admit difficult truths eventually winds up here.

Is there a time in the history of journalism where journalists were ever right about even the simplest consequential facts? That would at least explain why they're still considered a high-prestige field. Anyway, I'd love to find out how such a worthless field earned and continues to maintain it's prestige.

Ask HN: You have $1-5k – how would you bootstrap your retirement?
Good day all,

This is a hypothetical question, but I imagine a potentially useful one.

Let's say you're mid-thirties, working, with a family, house...all the usual trappings. However, you're not managing to save much (in this case, defined as something meaningful like 30% of your salary), and even though you put money into a retirement fund (say 10-15%), you know it won't be enough to see you through retirement.

You have skills (technical or otherwise), some financial savvy (have made some investments in the past, have a budget, etc), some free time (but not much) and, for the sake of argument, somewhere between $1000 and $5000 kicking around in a bank account.

How would you take this money, and make it into a meaningful nest-egg (20-30 years from now), while (initially) maintaining the status quo on the rest of your life?

Do you invest? Do you start a side project/business? Do you save some more, and buy a franchise (and let someone else run it)? Do you do something much more outlandish?

Has anybody done this? Success stories? Epic fails?

Very interested in reading your stories :)

>the difference in quality would be only the music itself

That's the technical side of music though -- not so the much the music as cultural significance / art, in which one could argue Dylan might be not just on par with Cole but probably much ahead.

Even if he could play with Mingus, many did, but only the very best of them we count as significant in general (Powell, Byard). I mean we wouldn't count Cole as among the top, but rather players like Tatum, Peterson, Monk etc.

If we judged only sophistication in the sense of chord changes, complex harmony, orchestration and such, then any half-decent conservatory graduate could be said to be better than lots of titans of song, not just Dylan but people like Lead Belly and co.

I, for example, would still consider Robert Johnson a better artist (more artistically significant) than, say, Steve Vai or Al Di Meola, even if those two can obviously play circles around him. And I think they'd might agree too.

Uh, The Shire being completely destroyed despite Frodo's successful quest? Frodo having to depart Middle Earth ? Are those all super duper happy endings for you ?

And of course the Sourging of the Shire could have fit in the movies, it was shown as a vision when they met Galadriel in the first movie. They had it set up and they changed their minds later on.

The ending in the movie is problematic because it follows some of the ends of the book without understanding why they are necessary -> they make Frodo leave Middle Earth but they never bother to explain WHY he has to leave. PJ clearly did not understand the books.

It kind of depends on how you envison that.

With existing intermodal systems, there's already something somewhat resembling electrified long-haul heavy trucking, though largely in Europe. For various reasons, the US has little electrified freight, and doesn't forsee it for the forseable future, though it's clearly technically feasible.

There are several other possibilities for electrified freight, though battery-EV is almost certainly out of the picture. IIRC BMW have experimented with a battery-powered EV tractor-trailer, but it's used exclusively for local delivery at low speeds (~40 kph IIRC) at a range of ~5-10 km. A very limited pilot.

Self-driving cargo vehicles capable of "training" on highways, with catenary or similar feeds, could offer long-haul separable vehicle cargo capacity. I'm not aware of any serious plans for such a system though, and it would require both massive investment in vehicles and roadways.

Present planning at the US EIA is for natural gas fueled cargo -- both truck and rail.

Apple's position is actually very easy to understand.

Don't do anything that is likely to cause significant harm to them. Examples of this include: (a) negative press publicity e.g. porn app, drone strike app, (b) stealing from or harming their customers and of course (c) this app where they will have to cover the cost of you putting heavy objects on something that it was never designed to do.

If you want to damage your own phone go ahead. You can build a weighing app and deploy it to your phone. But expecting Apple to endorse (which is what the App Store actually is) stupid behaviour was never going to happen.

"Here is the problem: why can't we have these guys painting actual art?"

Ever created visual art? Most art you see is commercial art. Capital-A, Art is personal. To create an original piece of art takes a lot of effort, be it something visually inspiring, a novel concept or deeply felt emotion. Apply some technique and maybe you might come up with something good, maybe?

"En plein air" isn't always practical.

Think of a photographs used in the way you describe, as the "Cheeze-Wiz" of inspiration for commercial art.

Is that true now that the latest ios/xcode combo allows anyone with an apple id to self sign most apps (those that don't require specific entitlements like push messages)?

If the problem is that you have to use a new app ID and cannot seamlessly install over the existing app, how is that different from using LGPL software installed in /usr/bin on a machine where you haven't been granted root access?

But companies equally have a right to own the experience. Creating an app to harvest hardware identifiers and using that to track them is legal. But it tarnishes the experience of their product and is anti-consumer by every definition. Apple should have the ability not to allow that.

Just because something is legal does not make it morally or ethically "right".
Per one of the comments, if you have what you think are rare books, and want to get them into Archive.org, what's the process?

While they seem to be landing a lot of enormous collections between this and the recent technical manual collection, it seems like there are whole lot of smaller individual books or sets of books.

I have a few books from the early 1900's that I know are out of copyright, and are quite interesting - science books where the highest pinnacle of tech was the new fangled thing called the "aeroplane", which was seen as far less reliable and likely to be a fad compared to dirigibles and other lighter than air conveyances.

Really really obvious reason they did this.

People are dumb.

Someone, probably very soon, and probably more than one or even ten people, would overload the weight and crack their screen. At which point they would show up at the Apple Store DEMANDING a brand new phone.

When they didn't get the repair because they're too stupid to understand how glass works they would contact CNN or HuffPo or whatever and there'd be a flurry about "glassgate" or something. Same way that putting a thin phone in your back pocket, SITTING on it and then complaining it bent set off a huge issue and tons of news coverage.

There is a walled garden, this is not an example of Apple overreaching though.
Most JVM-based query engines uses bytecode generation and once JIT compiler decides that the code block is hot enough and can generate native code for generated bytecode, the output is identical to C and C++.

The author actually indicates that every CPU cycle is important for code block that will be executed for each row. So once you optimize hot code blocks, you're good to go.

Baltimorean here. Most days these blimps can be seen aloft. They appear less distant than I know they must be (given they are tethered at the Aberdeen Proving Grounds). They are very,,, present. It is unsettling. I lived in NYC for five years where I'm certain I was often under "surveillance" (cameras and what not in public spaces). And during the Baltimore Uprising, we now know there was a FBI/DoJ surveillance plane in the sky. It's just different, in a very bad way, to be able too look up, at any time, and see billion dollar military blimps. Kinda sad.
Listen to the parent here, I've seen 10x performance in production Java code just using flatbuffers(and paying the marshaling costs from ByteBuffer).

CPU is probably not the best example, but the point is very valid, that at 100B scale anything is large.

We humans are not very good at appreciating orders of magnitude. I usually explain it this way: if it takes you 1 hour to process 1M records, then 10M will take 10 hours, and 100M will take 4.2 days while 10B will take over a year.

I'm not sure I understand your critique of my last point. I understand that many goods depreciate in value over time as a function of use and wear and tear.

I'm describing specifically the dynamics that cause a car that has been sold and driven 3 miles to be worth less on the market than if that same care had been test-driven 3 miles but not sold.

My argument is that while we tend to view the sale of the car as triggering a drop in value, that is not entirely responsible for the price drop.

The price drop is also a function of available financing options, since the vast majority of cars are purchased alongside a financing product... and the specific product used is not typically available to a customer wishing to purchase the vehicle that was sold and driven one mile.

Since price is a function of supply and demand, the price lowers (depreciation occurs) because there is less demand for the basket containing the car without OEM financing than there is for the basket containing the car with OEM financing.

This is what you'd expect, which is why OEMs offer financing incentives to increase demand.

My argument is not that depreciation doesn't occur (because that is the way we typically describe the "sold" one selling for less)... Just that without the financing incentives demand is lower and since price is a function of supply and demand, price is also lower.

The causality is important, since the topic being discussed was the mysterious way in which dealerships work.

My point in making this distinction is that consumers are buying a physical product and a finance product bundled together, thus there is room for significant innovation in the automotive industry simply by getting more clever/creative with how the car + finance + insurance are packaged...
