> Isn't a DSL just syntactic sugar in most cases?

I don't think so. Maybe with things like LINQ, but in many cases a DSL lets you abstract things to such an extent that you get a new way of thinking about the problem. That's why DSLs are almost always very high level languages.

SQL and regex are the obvious counterexamples, where you don't describe how to return the data you're looking for or how to store it on disk, you just describe that data and the language does the work for you. That's a completely different way of thinking about a problem compared to procedural logic. The languages allow you to describe very complex data in an explicit and unique manner, and in doing so allow you to abstract what the data is from how the data is maintained. Obviously, that can bite you if you structure your DB poorly, but on the flip side it allows people to learn how to use very complex descriptions of what are essentially abstract concepts instead of needing to know details that are extremely easy to screw up. Declarative programming is extremely powerful because of this, and it allows for extremely complex systems to be built on top of this new layer of abstraction.

A shell is another counterexample where being "just" semantic sugar is really oversimplifying it. You're in a fixed context with a default function, so you get a lot of acceleration over having to spawn all those processes by hand. You're stripping out so much overhead code that you're into a new level of abstraction where -- unless you need to -- you don't think in terms of procedural logic.

For a less straightforward answer, a generic programming language would be like a hex editor, whereas a DSL would be like PhotoShop (or even Paint). Sure, a hex editor can modify any type of file in any way, but the power of PhotoShop comes from all the power you get out of being domain specific. It's not just the additional built in functions the program gives you, it's also the manner in which the data are presented that allows you to see things which you simply would miss at the hex editor level. Here the abstraction is allowing you to see what the data actually represent instead of just seeing how the data exist in the computer.
One of the huge problems of requiring lossless photon transmission through fiber: This will break all currently known approaches to DWDM. It is not economical for inter-city transport between ISPs to require its own dark strand pair, no WDM of any type, in most scenarios. There's a reason why people want to be able to do things like 100/200/400GbE coherent frequencies in a 80-channel DWDM bandplan.

I think the problem is that it's logistically impossible to empirically test all your working hypotheses. For example, my working hypothesis is that Darwinian evolution is a true theory about the development of life on this planet. But as I'm not a biologist, I don't really have the skills to empirically test my hypothesis; I just trust that other people have done this and are doing a good job. Similarly, I believe reports that there are as many as 10^22 stars in the universe, but I won't test that either because I'm not an astronomer and I generally trust astronomers...

In other words, I think there is an intermediate category that deserves attention:

1) Beliefs that you refuse to revise
2) Beliefs that you could revise in theory but probably never will in practice (for lack of expertise, resources, etc)
3) Beliefs that you actively try to develop

We are limited in our beliefs by our material capacities for inquiry, sadly.
If you paid millions in taxes personally, then you have sufficient funds to qualify for investor/job creator visa (which in turn leads to a green card as well). I have family that were able to accomplish this with as little as 500K and 2 years, but depending on the scenario it can take as much as a couple million dollars (depending on location and nature of business). I am sure this is stuff your attorney must have explained to you so probably there is context I am missing here.

In the exchanges, no one seemed particularly surprised at the speed, just that it was relatively fast. So my WAG would be like mach .8 to .9 maybe? The anomalous thing they were focused on was that it wasn't squawking a transponder code, wasn't in radio contact, and possibly that it wasn't being well-tracked on primary radar.
That article claims “a number of studies support” while citing one study at first, then two more. The first study is solely authored by Uri Polat. The other two also include him as an author.

Sure, it's not a guarantee that the language will stay small and focused, but it provides a path towards that. Clojure has been around for a decade now, and the core language has grown very little. I think it helps that Clojure is a BDFL driven language as opposed to being a design by committee.

Given that Apple recently removed the ability to buy apps from iTunes, I think the writings's on the wall for the ability to locally backup iOS devices. Which is a huge shame.

As far as I understand the argument from people like Alex Epstein and a host of other climate alarmist sceptics is a little different.

Everyone is agreeing there is climate change, in fact there have always been climate change and according to them the climate have been much worse than it is now.

Most sceptics even agree that humans affect the climate.

The discussion as far as I can understand is to what degree do humans affect it. I.e. is it enough for us to worry about it.

There is as far as I have been able to learn no actual consensus, in fact, ICSC has been lowering their projections over the last 10 year or so.

If you want to figure out whether you should worry or not may I suggest you try and find out what the official consensus on humans effect on the climate is. You will be surprised how little certainty you will find. I certainly was.
Great article, I totally agree.

One area that I feel is also a "sometimes dumb stuff is better" that the article left out, is that (at least for me) hardware controls are almost always superior (tho certainly less flexible) than software controls. There's no better example than the physical keyboard vs. the soft keyboard. Recently I had to purchase a replacement stove, and I am amazed at how much worse the UX is on this stove than my old one. I don't want to slide my finger to determine heat intensity, and select which burner that applies to by pressing a soft button corresponding to the hotplate. Just give me a physical knob for each hotplate please. The UX there is excellent.

A more painful example is my Ford truck. Almost everything inside of it is software powered, and the bugs drive me insane. At one point my GPS/stereo touchscreen hit some bug, and the only way to "fix" it was to pull over at a rest stop and power cycle my truck (turn off, then back on again :facepalm: ). That is maddening. As a software developer I understand that bugs happen, but as a consumer I just can't tolerate that kind of stuff in my vehicle.

Without question tech has brought us nice things, but with complexity comes bugs (both security-related and non), and with bugs comes software updates (which themselves sometimes introduce bugs in something that was working fine before). Internet-connected things can also be a nightmare for security and privacy. Truly, sometimes the "dumb" version is much better (and way cheaper too).

Do they? How long does it take them? At 3 hours per 200 miles, 12 hours is 800 miles. Maybe you don't live in the western US, but it's a big place. If every gas station had a super-charger, range anxiety would be almost a non-issue, and travel time would be a noticeable but not intolerable problem, but we're a long ways from that.

EDIT, because HN sucks...

70 MPH * 3 hours = 210 miles. You might want to talk to some normal humans who don't frequent superchargers.
ATC primary radar is pretty weak. Not showing up (particularly after changing flight direction) doesn't mean much. It's very odd (and illegal) for something to be up in flight levels without a transponder though.
Many years ago (just after I left for college) my parents decided to build a brand new house. The plan was to include a computerized lighting system where every light was individually addressable and all "light switches" were actually banks of 4 to 8 programmable buttons. The possibilities were endless! What could go wrong?

I asked my parents to use a regular light switch in my room. You know the kind that I am talking about - it goes on and off, closing and opening an electrical circuit. It would have been less expensive and (in my opinion) more reliable since after all, it's just a few pieces of metal. I joked that "when everyone else's lights are flashing on and off at 3AM, I'd like to remain asleep". My father accused me (his resident technologist) of being a Luddite and they went on their merry way, finishing construction and installing a fully-computerized lighting system.

A few months after they moved in, I got a phone call from my father that started something like this: "Please don't say 'I told you so' but I have to tell you what happened at 3AM last night..."

(they flipped that house, and when they built their next one, it had regular light switches)

The "second" in "second preimage" doesn't refer to hashing something twice. It means that you already have one preimage for a hash (presumably because you started with the "preimage" and calculated the hash from that), and you want to find a second, different one.

Primary radar is good enough to pickup a 2500# single engine airplane from 50+ miles away.

I flew from Detroit to Boston a few years back in a 4-seat, single engine airplane after an electrical failure. On a hand-held radio and with no electrics, ATC had a good primary target on me the entire way (at 5-9K feet). On controller handoffs, I would have to turn north for 1 mile for them to confirm the primary target they were looking at was me.

Up and down the Eastern seaboard, I pretty regularly get traffic called out as "primary target only" which also means ATC has no idea of the altitude. Those tend to be low, slow moving aircraft (often without electrical systems).
Basically they are claiming one of the core primitives to make IOTA work as a secure cryptocurrency is fundamentally flawed. Haven't read enough but if this is what it sounds like, it means IOTA needs a major rework.

This is cool and I definitely appreciate that this page exists. Cool page!

However, totally absurd—Donald Trump levels of absurd—to say you invented a knot. Not only have mathematicians categorized every possible way to make a knot, but before that hundreds if not thousands of generations of sailors and knitters certainly discovered every kind of knot that could be made. Very strange to think you could have “invented” a knot... borderline disturbing to be honest.
Most of the speculation here hinges on it being an advanced aircraft that successfully evaded the USAF. Though it's entirely possible that that is easier than it sounds.

Given that assumption, the answer to your questions are:

> Why military?

The assumption here is that the military goofed, didn't tell another branch about it (hence the USAF scrambled), and is avoiding either embarrasment or needs to keep the deployment of the craft as secret as possible. This probably happens on a regular basis (though if we have data on how often that happened during the Cold war, that'd be useful), and explains why USAF couldn't find anything.

> Not smugglers

I have never heard of smugglers having advanced aircraft that would be flying around Oregon; Seems pretty risky. Also, doesn't make a ton of sense as you presumably wouldn't be able to transport much with a high speed aircraft.

Definitely an interesting proposal, have you heard of smugglers having advanced aircraft?

> intelligence services

Possible; Which ones, the American Intelligence Services? If so, I believe the parent was lumping them in with 'military'.

Though it still seems more likely that this was just bad internal communication, mostly because I wouldn't expect a foreign spy plane to be ever be caught flying at high speeds; though it could be a generic attempt to test the US response. Be great if anyone has any data on how often that sort of thing happened during the Cold War.

> just an asshole

Seems very unlikely. What random assholes have access to advanced aircraft that can evade the USAF?

So under the assumption that this was an advanced aircraft, the most likely explanation is government, either the US's or a foreign intelligence service. Since presumably the US is in control of it's own airspace, the idea that this was the US itself seems the simplest explanation.

Yeah I've heard stories of some people doing crazy, dangerous, illegal things in small planes and just turning their transponders off.

I was a passenger in a C182 once where the transponder antenna fell off midflight. It was very educational how much trouble ATC had seeing us. Even after telling them exactly where we were, flying the heading they gave us to present the broadside of the a/c to the radar antenna, they basically said "there's something that might be you there, but I can't really tell."

A big jet at FL370 should show up on primary, but I can see it depending on a bunch of factors.
The bonds were significantly more certain than the commons, since owners were generally not subject to dilution risk. I was not referring to the height of immediate post Lehman uncertainty. Even after the Treasury Department bought preferred shares from the financial companies, thus subordinating the US Government to the bond holders, some of the bonds were still trading at very significant discounts (> 50%) to face value. I am not advising anyone to take risks in such investments. However if one can't deal with credit risk/reward at such advantageous terms one also shouldn't fancy that one can deal with the stomach-churning volatility of equities at such trying times.
This isn't criticizing bank robbing. It's just saying that cracking down on the bank robbing, might not make restaurants any safer. Only claim was that restaurants (hitech companies might benefit).
IOTA rolled their own crypto. As they were warned by many in and out of the crypto (in both senses of the word) communities at the time, it was susceptible to attack. MIT Media Lab wrote a responsible disclosure report on a vulnerability. IOTA kept pushing back the publication date, based on a mixture of amateur cryptography arguments and nitpicking over disclosure issues. MIT Media Lab finally published, well after the originally agreed deadline, after realizing IOTA was not serious about improving the code further and was using the time to attempt to improve their appearance in the disclosure report's narrative. IOTA got upset, as this publication exposed them with their pants down. They've now threatened the involved academics with legal action. (There is, of course, no actionable basis for such.)

It is interesting if you find cryptocurrencies interesting, as it shows how "well" run many are - and IOTA is by no means an outlier here. The foundations are simply not lousy with cryptography, programming and economics experts who are solely interested in best practices.
Now that you recognize it, you can escape being part of that machinery. It will require you to nurture your conscience, though.
I happen to live in the western US. I run into tons of other Tesla owners at superchargers, not surprisingly.

The usual drill is to drive around 120 miles and then stop for 10-15 minutes to supercharge. So yes, that is a bit more stopping that I used to do.

Tesla has a trip planner at tesla.com/supercharger

For Palo Alto to SpaceX's factory, it recommends stopping for 50 minutes in Kettleman, which means you're charging for 13% of the trip time.

It wouldn't be the same nazi's nowadays - their uniforms would be different, their slogans would be different, the group they scapegoat all their problems on would be different.

But they'd still be plowing through imprisoning and killing people who fit into their nearly arbitrary category not caring what kind of people they actually are because "their group is the reason why bad things happen!".

They'd simply go on their facebook feed, be told who they should hate this week, and gleefully post about how they're being put in camps to slowly die, all the while convinced they were doing the right moral thing.
