You are correct about clustered indexes (1) if and only if the table clustering is selected well. Which is not always the case - especially with Azure SQL which doesn't allow for non-clustered tables or tables clustered by anything other than primary key.

Table clustering is mostly betting on "I think most access is going to happen using this columns" which might be good choice or it might not, but it's not something that should happen implicitly or by the only choice at all.

I think Markus (2) explains this much better than I do, so I'll just link his text.

(1): which is pretty stupid name, btw - Oracle call it "index organized tables" which is much clearer way to describe the concept.

There was a nice passage describing O'Sullivan in an article [1] posted on r/snooker recently:

"For years, the main frustration for the keen snooker fan was the apparently immutable dichotomy between the monotonous winners and the flamboyant losers. It seemed that we could either have the unflappable resolve of a Steve Davis (six-time World Champ) or the charismatic fragility of a Jimmy White (six-time runner-up), but we couldn't have both in one player. By only self-destructing either before the start of a tournament or after winning one, O'Sullivan has cleverly defied this convention. He doesn't fall apart in the crucial stages of a match; he plays consistently throughout, either like the greatest player in the world or only, say, the twelfth best. It all depends on which Ronnie shows up."

I don't agree with you. This has been a problem for almost 15 years. I can't get stuff done. I can't focus. Music triggers it, and I can lose entire months just doing nothing but daydreaming. It's been a genuine problem.

Doctors thought it was ADHD, and it could have been. But the medication hasn't helped with not triggering it. I'm going to look into the medication stated in the article. But where I am, the doctors are stringent with prescribing things. Took a year to ADHD pills.

Although it sounds like she doesn't really have enough money to live comfortably on. It does imply in the article that she isn't sure of where she should spend her money. Dollar store vs. Walmart for groceries, ect. With a consistent paycheck, then she would know exactly how much she can spend on groceries and other things. Often it is the unknowns which cause people to mismanage, not that the managing was impossible to begin with.
My two cents on the slow upgrade cycle: tablet users just don't care.

Phone users upgrade for two reasons. Status symbol, and phones get abused. You need the new iPhone. You drop your existing iPhone. You lose it. People are more careful with tablets. At the coffee shop nobody gives a crap if you have the iPad or the iPad Air.

Not to mention that tablet users aren't as techy as laptop users or even phone users. Seniors love iPads. They don't see what the hubbub is all about with the new models. They can't see well enough to care about Retina screens. They don't like change and they don't see any point in spending $400 every 2 years on the latest stuff.

FTA: "Will maladaptive daydreaming ever end up in the DSM? In the most recent version, hoarding and skin picking made an appearance for the first time, as a part of obsessive-compulsive disorder. For people who suffer from these conditions, this means they can now receive treatment and insurance reimbursement for behaviors that were previously considered odd but not pathological."

Am I the only one who worries about everything and anything ending up in the DSM, to then be controlled by medication? Unless what's going in your head actively interferes with your day-to-day existence, why does it matter what you do?
Having read the entire article, I'd say that while it's good to consider the implications of encrypting all traffic (including those mentioned in the article), it's perfectly reasonable to have done so and still come to the conclusion that every single one of those implications are entirely by design features, rather than bugs.

"Lawful intercept": sure, you have the right, good luck with that. We're not going to make the Internet less secure for the benefit of government interception; if anything, we're making it more secure because of the possibility of government interception. This one is a very old argument, and easily debunked: assuming you allow any encryption at all, just having less of it doesn't make lawful interception any easier, because of course all the illicit traffic will be encrypted. The only thing it does is make encrypted traffic seem more suspicious, which isn't good for anyone.

SNI works just about everywhere these days, and it's quite safe for most services to just turn it on and write off the few systems (IE on XP, and truly ancient mobile devices) that can't cope.

People don't get used to clicking certificate warnings away because browsers have gone out of their way to make that painful, and it should be.

If you don't understand TLS, learn, or count on other people to have learned. That's no excuse for not using it.

There are many folks working on fixing the CA problem, but even without that completely fixed, SSL is still better than cleartext.

All that said, I do think the first section of the article, about unintended affordances (such as emergencies) is worth considering in other technological contexts. That point was made years ago: http://code-is-law.org/

Personally, I dislike comments that just criticize commentary as "hindsight." If it were technologically possible to discuss these things before they happen then I'm sure we would do it, but for now we're stuck with traditional concepts of causality.

I imagine a lot of people on this site have considered renting on AirBnB. Certainly I have. It's a hip service, it fits in well with our techie notions of the world, and you make a little extra cash. Perfect!

Then I came to my senses and decided that the risk to my house, where I happen to live and in which I place great value, wasn't anywhere near worth the relatively small amount of money it would bring in.

If you thought it through and decided it's not worth the risk, it's hardly "hindsight" to point out when somebody else clearly got it wrong.
The usage of RHEL is public, but I don't know if the numbers are public. If I can dig them up I will. My sources are a few ex-RedHatters.

If true it's concerning because RH has a huge influence on everything in the base repo, so that reverberates out to the greater open source community. Not cool when you think about the possibilities of influence the US Military could affect.
>There is the idea that “there is no such thing as insensitive web traffic” and that the privacy of communication is absolute.

The essay seems to center on "privacy" and "hiding".

The other use for encryption is "authenticity". We want to have trust that the pixels on the desktop monitor or iPhone are actually correct. Whether a user is a city administrator looking at weather.com pixels to decide whether to shutdown schools for the day, or a grandmother looking at NYT or Yahoo pixels to check a stock price before selling, encryption helps ensure the veracity of what their eyeballs see.

Grandma doesn't care if the government or Facebook knows she read the New York Times. Someone on the subway can look over her shoulder to discover that same datapoint. On the other hand, she does need to have confidence that what she reads has not been tampered with.

One could attempt to write "data protection" protocols that send multiple hashes to verify the payload. However, if the hashes are cleartext, you're back to where you started with broken trust because the hashes can be spoofed. The necessity of encryption (without regard for hiding or privacy) appears again.
I think this is fairly self explanatory. Since iPad 1 launched, phones got bigger-better and the median laptop got more portable (weight, battery..). If you take a bag, your little laptop can come. If not, phones fit in pockets and need to come anyway. The space between the two got smaller, I agree.

My 3 years old Ipad's job is mostly watching movies on planes. It does that job well enough and I won't replace it unless it breaks. I just don't need any more from a tablet.

Honestly, I think iPad's will almost go the way of the ipod, but with tougher competition. Good enough.

OTOH, if I was king of the apple…. I think a good idea for a new product category is a ~€500 iOS laptop. Chrome OS is selling well, and I think Apple would probably do a better job in that general space. Iphone apps could run as 'widgets" which would automatically tick a lot of boxes (Skype, VLC.. whatever your non negotiable apps are).

There's still a poorly served market here. Home users who don't like computers much, don't want to spend a lot and need something simple that works.

I don't know if you still call that an iPad, but I reckon it'd sell.

Finally something concrete from these guys! They've been working for over 10 years on this and shown almost nothing.

The capsule looks nice; big curved windows and no RCS thrusters tell us that this is not an orbital capsule.

The 1st Stage reuse concept is interesting; the ducting near the capsule connector is quite novel. There are 8 large spoilers that protrude into the airflow to help slow descent. I wonder if these can be modulated to give some kind of stability control?

It's interesting to note that although the capsule landed successfully, they make no mention of what happened to the launcher. I presume that it failed to land, but I didn't see any smoking wreckage in the background of the capsule landing video, so maybe it made it down in 1 piece? I'm sure they would have told us if it had.

Anyway, a good day for the US space industry; Blue Origin finally have something cool to show and have proved that they're not just purveyors of vaporware. I'm looking forward to seeing what else they can come up with.

The cost of bulk shipping an iPhone by air from China to the U.S. should be around $0.25-$1.00 and by sea would be about 1/5th that price.

Assume they can earn 5% on their cash hoard with smart, conservative investments.

If they have a $600 phone (they sell them all for that price) at sea for 1 month they would have earned about $2.50.

They sell the phones as fast as they can make them, and if they don't have a phone in stock and someone desperately needs a phone, they may buy an android, so that's revenue they'll never see again.

When we're talking about $0.40 savings to have to delay $600+ in guaranteed revenue by a month. That's all I need to see to know do air every time.

Of course we also know that Apple manages their entire supply chain with just 5 days of inventory in stock at any give time. Much harder to do that with ocean freight.

The author seems to be calling a lot of things effectively bugs of encryption that I see as features.

>Unfortunately, SSL prevents this. Unfortunately because it means that if a website hosts partially illegal shared content, then the whole website is down and not just the subsets of it which are legally problematic.

>But not everybody is entitled to privacy in all situations. For instance convicted criminals are not. Likewise many lawful professions need to be heavily surveyed for security.

>a pilot hid his psychological problems from his employer and intentionally caused a plane to crash.

In my view this is all valid reasons to encrypt everything. When prisoners are made such based on unjust laws, I say that anything that gives them their rights is good. Forcing a government to be very overt about its censorship of websites is good. Allowing people to hide their mental disorders in a world where a mental disorder is still seen as a moral failing is good.

Encrypting everything enforces a positive change on society. Governments have to be more open about their censorship, allowing for greater discussion. Dissidents can communicate in secret, allowing for greater freedom. Critical systems have to be built so that a single individual cannot cause a large loss of life. Groups that are required to be surveyed must directly incorporate it into their systems

As for the cost of using SSL, my understanding is that they are much overstated.

Google does do a very good job at this for online maps - but as you can see in his photographs, it is absolutely the wrong choice for a wall. Having the ability to change the labelling of a map to suit your needs is cartography and the OpenStreetMap map making toolkit is one of the better ways of achieving this.
So here we have someone who does not understand how gates work trying to talk about encryption.

Having taught javascript to coworkers who were proficient in other languages (c++, c#, ect), javascript was confusing to them since many things act differently in javascript from other languages. That said, with the availability of online help and tutorials, you could definitely get off the ground with it, but it will give you a very different experience than something like python. Depends if you are more interested in programming fundamentals or in web programmings. If you are looking for fundamentals, I would learn Python or Java.

Gall-Peters is also a conformation projection that maps north-south maps to the vertical axis, and east-west to the horizontal axis. As to online maps one major advantage is the X-Y scale does not get nearly as messed up at multiple zoom levels.

However, online maps alter the projection as you zoom so this is not much of an issue.

Those "non-violent means to redress problems" work great in theory. I would even agree that society ought[1] to work that way. Unfortunately, a working political[2] system is not a fundamental law of nature. Far too many people seem to think it is, which leads to the common belief that the law on paper has any reliable mapping to what happen in reality.

P-value related articles have been popping up on HN recently, but I'd like to say that another place needing scrutiny is probably back at the beginning in model specification. Bias introducing model design at the beginning render the rest of the analysis essentially meaningless.

I know you're joking, but sometimes I wonder if "lies, damn lies, and statistics" isn't one of the worst phrases ever uttered in the English language. It's been a way for people to just say "hey, it's just a statistic. who cares!" and continue doing whatever they're doing. It's become this terrible meme where someone who openly admits that they "aren't a math person" gets to thrown down this trump card saying that your analysis is bullshit.

But hey, I'm a baseball fan.
I take issue with these arguments.

I respect the author but this doesn't read well reasoned.

Firstly CAs not being equipped to scale and the inevitable mistakes that will happen in a highly manual process. Thankfully this has already been resolved, we have DNS - if you are in control of DNS you are authenticated. This is is the system to be used in the EFF automated certificate issuing protocol.

As for CPU cycles we have Moore's law (which is still in full effect for things like SSL decryption). That and many many motivated engineers.

The next bit is where things get sour.

It seems the argument is because law enforcement has the "right" to read your traffic that anything you do to dissuade them will only result in further systematic destruction of privacy, i.e MITM attacks on SSL.

The final points around complexity do make some sense but those are against SSL, not against encryption IMO. SSL and TLS are both hugely complicated but this need not be the case.

As for my point of view.

We need encryption. Why? Because communication has changed.

Communication used to be manual and as such the attacks against it were manual and unable to be orchestrated at scale.
Government surveillance was better understood because communication was simpler so lawmakers couldn't destroy all privacy accidentally.

Now almost all communication is digital, it's become economical to simply subvert -everyones- privacy.
Lawmakers are at a loss to understand even basic computer science let alone what motivated and technically sophisticated "law enforcement" agencies can do with such massive amounts of information.

We need encryption to save privacy before it's lost forever.
Assuming there's no coercion occurring, I would say yes.
That would really be a great feature.
> There's little to no hacking in this project. Just the bit where he makes something custom.

Well the whole damn map/project was custom. Seems as the same amount of "hacking" as most posts in this sub, except this was not made inside a computer.
This interest free loan makes it VERY susceptible to fraud or abuse.

A buisiness which cannot pay the full prrovisioning cost of labour is one which is fundamentally uneconomic. There may be reasons to choose to subsidize such businesses given net social benefit and market failures resulting infailures of prices to meet costs.

But profitable businesses, such as Walmart and McDonalds, which choose to pay below-subsistence wages are getting a handout directly from taxpayers, and are shifting risks onto the backs of workers.

That a man must always live by his wages was recognized by Adam Smith. And not just the worker himself but his family, children, and their education.
