> Essentially, all you're signing up for when you use a 3rd-party DNSSEC server is that someone's misconfiguration is silently going to break your queries.

Isn't this literally true of any service?

> What's especially funny about this is that your DNS queries to these third-party servers are not themselves encrypted;

This would be relevent if people were aiming to protect the confidentiality of their DNS queries. They're not though. They're trying to protect the integrity of the DNS queries.

Anyhow, I find it useful in that I can store SSHFP records in my DNS zone and then use `VerifyHostKeyDNS` when I'm sshing into servers. This becomes especially useful if I've got servers sshing into other servers and I don't want to have to lug around a known_hosts file on every server.

Saying things like "using DNSSEC is pure downside" is so easily demonstrably false and hyperbolic that it may cause people to ignore the rest of your argument. Which is a shame, because I know you have very insightful and interesting things to say about a lot of things.
This is very similar to another product that you can buy today https://www.adafruit.com/products/1652. It's basically an iPad 3/4 retina display that connects via DisplayPort. The main differences seem to be that the Kickstarter one will run off USB power (instead of 9V) and attaches to your laptop screen.

I've been tempted to try it, but can't really think why I'd need it.
The key takeaway for me here is that it is much more difficult to access data on iOS devices if they are switched off.

So, if you are in a situation where you can expect that your device will be accessed (e.g. crossing the US border), switch it off ahead of time.
I believe DNSSEC is, across the board, pure downside. But that statement is especially true here, in the case of a third-party resolver with DNSSEC enabled. And that's the case I was talking about. I don't think we have to reach the wisdom of SSHFP records to refute your rebuttal.

The USA has a history of doing racism based only on skin colour. But in many other countries there have been "culture" /"ethnicity" based racism. This is what your noticing. Accent (ie. culture/ethnicity) racism.
Since people are mentioning other sports, for an analytical study on golf's pace of play, see Golf's Pace of Play Bible, by the founder of the three/45 Golf Association -- http://www.three45golf.org/?r=no -- and a colleague at Columbia Business School. They found that studies showed that the current slow pace of play is the biggest obstacle to enjoying and growing the game. They analyzed golf's play with business operations analytics, like queueing theory.

I thought people liked to play golf to relax, but waiting for others isn't relaxing. It turns out that speeding the game through a few changes improves the experience for everyone -- not just players, but the club as well. They talk about principles everyone can do to improve the pace.
>My point was about the decline of US industries, not about the income of workers.

You probably shouldn't have said "What destroyed the US industries...was the high price of labor" then, should you?

>What matters here is the price of the produced products and you're at a disadvantage in a global economy when the prices are too high.

As I explained once before this is due to the high value of the dollar.

>I suspect that either option (reducing wages or value of the dollar) would reduce buying power of US citizens since US has to import so many goods thus creating downward pressure no matter which option you choose.

Reducing wages reduces buying power period. Reducing the value of the dollar only reduces the buying power for imported goods. Right now I think flat screen TVs, jeans and cheap plastic crap from China are cheap enough and it wouldn't hurt for that stuff to go up in price a bit.

Housing, education & healthcare are the major line items on household budgets. THESE things won't go up in price.

>Anyways, I agree that those problems have to be solved but I'm quite sure that the current consumption level is unsustainable

Current consumption is too low to support full employment. In the EU and the US. This has to change. Both economies need to engage in massive debt writedowns and/or stimulus to return demand to normal levels.
It's not dead.
It's not dying.
I'm not even convinced that it's wounded. If it is then it's definitely only a flesh wound.

It's a bit like concrete in the building industry. Yes you can make buildings without it, no it's not the sexiest thing. But you look around and somewhere at the bottom of most buildings there'll be some concrete doing the hard work.

C's like that. You can envisage a world without it. You might even prefer a world without it. But it's there and it's not going away in a hurry because a fair chunk of the foundations of our world are built on it.
On a similar note, does anyone have any experience with the apps that let you use your iPad as a monitor? Last I checked they were a bit flaky, but I was wondering if the situation had improved (and if they work when connected to e.g. public wifi, or if you need a private network to connect them).

Would be nice if Apple just allowed you to connect one directly via the Lightning port via Airplay.
Not trying to disagree with you:

As far as I know racism stems from one race thinking they're more human than the other, which occurs, I think, due to the perception of differences in intelligence when the perceived inferior race is trying to communicate, in a sub-optimal way, to the perceived superior race, and being constantly made fun off in the process.

I imagine a typical racist comment in 18th century America: "There's no point telling the slave, he's not gonna understand anyway.".
My problem may be laziness. I couldn't bring myself to read more than half of such a long article, so I guess I'll just stay moderately unhappy.
Some companies don't pay _taxi_ travel costs if there is a cheaper alternative (e.g. shuttle busses)
Aside from the comments above, I would add "shopt -s shift_verbose" which
enables "overshifting" detection.

E.g. when a function receives less arguments than necessary and you retrieve them like this:

function f()
{
declare -r x="$1"; shift
declare -r y="$1"; shift
declare -r z="$1"; shift
}

with less than three arguments passed and shift_verbose on you will get an
error message the moment you shift and with "set -e" in addition, execution
will be aborted.

See https://www.gnu.org/software/bash/manual/html_node/The-Shopt...

Also, "set -o noclobber" might be useful. If you try to
redirect to an existing file with ">", it will fail. If you explicitly want to overwrite the
file without triggering the error, use ">|".

See https://www.gnu.org/software/bash/manual/html_node/Redirecti...

>The US still exports a lot, and is a leader in services and knowledge. Sure, china produces iPhones, but all the R&D is done in California.

Unfortunately that R&D created maybe 30,000 jobs. This is an economy of 300 million people, so that's good jobs for 0.001% of the population.

What about the other 99.999%?
Sorry! That was a typo. Ment "module".
Don't understand why they didn't just make an iPad mount. There's plenty of software to extend your desktop remotely. A small display like this doesn't need to be able to run high frame rate games.
Ugh. You don't even know the age of the boy, or if he even intended the cow's eye to be hit (maybe he was just throwing a rock to see it jump?), and you're ready to judge that punishment as well-deserved?

It's all hypothetical, of course -- and no one is removing eyes based on your say-so -- but that's a shitty punishment for anything.

Generally a punishment for a wrong-doing should try to encourage/force the guilty party to be a functional, non-destructive member of society if at all possible (exceptions as needed to protect others).

Punishments that harm the person's ability to earn a living, or have normal interactions with other people, are counterproductive (and can force the person to resort to criminal behavior to survive in the future), so punishments that inflict serious physical and/or psychological damage are stupid. They give a few people their "vengeance", for whatever that's worth, and otherwise they damage the society as a whole.
Hilarious, I didn't pick that one up since it's in the later chapters I skipped..

The bstring thing and his safer copy function are still my favorites for the irony of it. He's sounds so condescending when he attacks C strings and an old K&R example. And then goes on to show how to do it wrong, without really even solving the problem he's trying to solve. And he keeps repeating the lie about C strings just being nothing but an array of chars.
Ask HN: Would anyone be willing to share an image of their workspace?
I always find it inspirational seeing other people's work environments and would love to start a collection of images. If anyone is interested then I'd love to include your workspace! It doesn't have to be your dev battlestation, it could be the quiet corner of the house where you paint, or the coffee shop around the corner where you write a little of your novel every morning - if you do work there, then it's a workplace!

It's fascinating seeing what gear people use as well. If you've ever seen http://www.everyday-carry.com/ then you'll be familiar with the sort of thing I'm talking about. If you can then include a list of the gear you use (your computer, pens, the type of coffee you drink - whatever it is, someone will want to know what it is!) and the sort of work you do (Software Engineer, artist etc.).

It would be great if you could post them to this thread so other people can also find inspiration - otherwise feel free to email them to me (my email is in my profile).

Thanks!
"Shock" will come in the form of conspiracy theorists getting a bump in popularity, further distrust in government (and Netflix streaming an unseemly amount of old X-Files reruns), but mostly in disturbing thousands of years of dogmatic religious teachings that will shake the moral foundation of most of the world.

True, some microbes won't be as meaning-of-life shattering as other intelligent (or even large, multicellular) animal-like life forms, but way too many people believe God created us and only us.

Which is sad. Because looking at the current state of humanity really makes me hope God tried a few more times to get it right.

How to Persuade Anyone of Anything in Ten Seconds
Though my wife says she'd be happier to go to games if they were just about six innings long, I don't mind. I enjoy the atmosphere, particularly at Wrigley Field where there's no attempt to keep everyone distracted every second with per-player at-bat song themes and audience participation games during every inning break. The game is designed to be deliberately paced and reflective. Enjoy it for what it is. Pitching and hitting will ebb and flow as it always has. Strategies will change. But the pace is fine.

Devcoin : a Bitcoin-based currency for technical help
Exactly that way it is done.
I've reduced it to a series of equations:

Happiness = Perceived Actual Life / Expected Life --- (1)

where,

Perceived Actual Life = Perception * Actual Life ----- (2)

and in most cases,

Expected Life ∝ Perceived Life of Others ------------- (3)

where,

Perceived Life of Others = Perception * Others' Actual Life -- (4)

and finally,

Actual Life ∝	(1 / Happiness) * Skill * Circumstance - (5)

The most success I had was in breaking equation (3), and then in upward adjusting Perception in (2). But (5) is the kicker -- it implies that your lack of happiness feeds back into other people's lack of happiness, creating a loop. As long as it holds, everyone will try to one-up each other in trying to improve their lives.

EDIT: corrected error in (1)

Hehe :)
DNSSEC adoption is growing each year. Constantly dismissing it does not make that fact nor DNSSEC itself magically disappear. You mention that the queries themselves are not encrypted, but know (I hope as a security guy) that it is not the goal of DNSSEC, so why bring this up?
In a perfect world, perhaps every query will be done over TLS. But until every piece of the chain guarantees this, DNSSEC is necessary to ensure the answer wasn't spoofed. You can think of a million better alternatives, but it's extremely hard to get the whole world to change...
>Assuming they were actually keeping the contents of such wordlists out and actually ensuring high-entropy passphrases, we would be in an OK place, though still far removed from the security provided by randomly seeded ECC keypairs.

I'm fairly skeptical of the ability of software to "ensure high-entropy passphrases". I don't think it's trivial to anticipate the entropy-lowering strategies that people will come up with in order to help them remember their passwords.
Good point. I try to take public transport on business (and personal) trips whenever that's reasonable (which is subset of those times when it's cheaper).

In many foreign countries, the taxi is so much easier than trying to figure out public transport that the taxi wins. In many US cities, public transport doesn't get you close enough to be reasonable alternative, even though it would be less money out of pocket.
This topic popped into my head during the HOPEX talk on biohacking yesterday. The thought was that diybio enthusiasts might be a perfect partner for the OpenBazaar project, who are building a decentralized p2p marketplace. It's mostly associated with the drug trade atm.

I mentioned it in #openbazaar on irc, and they seemed interested. Toronto has one of the largest diybio groups in north america, and I've been to a few meetup, so I'd love to help look into it when I'm back in Toronto next week

frankly, I would be thrilled if the nixhe groups of both cryptocurrency and diybio found symbiosis :)

That's what always amazed me. Are the banks rich ? When inspecting their balance sheets, assuming (probably wrongly) that they're not hiding anything, I'm richer than they are percentually.

Now what I mean by that is that if you take the ratio of assets + money I own and divide it by the money I owe, and even ignore things like the NPV of my business (unless I close it tonight, it's not zero, right ?), then that ratio is a lot bigger for me than it is for stuff like JP Morgan and so on (for one, it's significantly bigger than 1, somewhere between 1.3 and 1.5, hell if I'm optimistic on my house, maybe even 2, but I'm dreaming. JPM is nowhere near 1). That's how banks' capital works : lots of big loans. The majority of their capital does not even actually come from their shareholders, but from fractional reserve banking. Most banks have values that are below 1, which you would think makes them bankrupt, but I guess I'm seeing that wrong.

Creating a new bank means you effectively get to multiply money, over time, by a factor of 20 to 50, depending, assuming you can make enough loans and deposits. Given that that's how that works, how can that possibly not be a crime ? The more I read about that, the more I'm inclined to go into finance and find a few more of those kinds of transactions I can do.

So can you explain a stupid question to me ? Why can't I borrow the amounts these big banks do in my own company, skim off 2% for myself (they, on average, do about 4%, so 2% seems like a sweet deal), and be richer than Bill Gates (by a very nice factor) ? Sure I can't afford the lawyers necessary for doing that, but ...
I hardly agree with "Develop the skills and habits associated with extroversion". Why I need to be comfortable with social company if my predisposed nature and comfortableness is to be alone ?

I'm in Victoria, BC, which I find much more pleasant than Phoenix on average. I say we have two seasons in Victoria; spring and fall.

The winters in Phoenix were great, but the summers were brutal. Average them out and you get an ok year. Also, the landscape in Victoria is so much nicer that even during the rainy season (it never gets really "cold" in victoria, particularly by Canada standards), I can put up with more than I ever could the heat in Phx.

Alt-S is used as "send" in many IM-applications.

Alt together some character is used as hotkey in ALL applications. Hold it down and you will see a small underline under (usually) the first character of most buttons, press this character on the keyboard and the button will be pressed. I think it would collide with S quite frequently. It is AltGr-S you are supposed to use for localized S-characters.
I'm not really sure what problem this solves.

If I'm on the move, I tend to be working either on the train or in a coffee shop, and neither of those environments would be conducive to attaching an iPad-sized display to the side of my laptop (on the train, this would just not work at all; in a coffee shop, it might at a stretch, I guess).

If I'm in one of the two fixed locations I tend to do work - either my office or one of my clients' offices - I will already have access to a much larger and more usable external display.

There are also a bunch of apps for the iPad (and other tablets I'm sure) that'll do more or less exactly this over wifi, which will probably perform adequately (for some tasks).
Also American made "documentaries".

I cannot watch a doco made by Americans, its infuriating. Maybe 13 minutes 9 seconds worth of content stretched over 55 minutes of excruciatingly repeated cut scenes of the same damn clip over and over and over again. I once made a point of counting them. The same content, exactly the same footage shown 6 times, I quit watching about then.

Now compare that to anything by David Attenborough.

Actually, on a percentage of zones signed basis, or queries issued, DNSSEC penetration shrinks each day.

He mentions encryption since the vast majority of people believe DNSSEC provides some level of privacy, encryption, or security. Most of us in the industry who aren't financially aligned to support DNSSEC recognize it does little to nothing in this area; while simultaneously adding complexity and brittleness.

The only benefit DNSSEC offers (imho) right now is DANE-like services. And guess what? There are much easier ways to accomplish that.

Because you have a lot to gain by doing so. Humans are capable of deriving a lot of happiness from social matters, so there's a large opportunity cost to being alone.

That said, it obviously depends on the person's situation. I don't think the advice is good for everyone. But it's probably good for most.

Just for those of you who aren't aware, LessWrong is a site devoted to the cult of the "singularity." The site founder, Eliezer Yudkowsky, is a secular humanist who is probably most well-known for his Harry Potter fanfiction, "Harry Potter and the Methods of Rationality." His core beliefs include that the obvious goal of the human race is immortality, that it is justifiable to kill a man if it would remove a spec of dust from the eye of every other person on Earth, and that the most important thing we could possibly be doing right now is devoting all of our time developing a mathematical model of a "safe AI." The site frequently dallies with discredited ideas like Drexlerian nanobots and some on the site take absurd concepts like "Roko's Basilisk" [1] seriously.

All of this is not to discredit this specific article. And there are lots of very intelligent posters there. But I tend to take everything I read there with a massive grain of salt.

Actually there are four hard things: cache invalidation, naming things and off-by-one errors.
Just to add to why you would or would not want to use the passphrase vs. the abbreviation - I've personally found that I find it much easier to actually type a password that consists of words, names or "nonsense words" generated by Markov chains (though not usually ones generated by letter frequencies).

I am often comfortable entering in a given password on a device on which I am not comfortable unlocking my password database (or entering my password database password + keyfile), but I usually have a device which does have my password database on it (phone, laptop, etc), so my application is "it doesn't have to be memorable, it just has to be something I'll enter without making a typo". For whatever reason, I find that entering in "tidlotexidaifol" would be harder for me to do accurately than "tidy lot existence daily following" or "tidylotexistencedailyfollowing".

That said, I like this approach, because some sites (like Bank of America, shockingly), restrict total password length, making a "very long password with relatively low entropy per character" approach infeasible.
