There's been a few subsequent articles mentioning Amazon's ability to hot-patch Xen without a reboot. They didn't perform a reboot for this vulnerability.

"There's another TB statistic that's particularly worrisome. The new report estimates that there were roughly half a million cases of multi-drug-resistant TB last year, double the number from the year 2000. Conventional antibiotics can't cure MDR-TB. Treatment can take two years or more with drugs that cause severe side-effects; some patients are left completely deaf."

I did a semester-long report on TB in college, and our findings were that multiple drug resistant TB and poly-drug resistant TB would be growing public health problems in poor countries in the coming decades. This was a conservative way of framing that problem. Realistically, TB is wildly infectious, and extremely dangerous to societies that can't afford treatment.

The clinch is that TB is entirely treatable, but it is very money and resource intensive to do so, requiring reliable access to medication and quarantining from healthy people over a long period of time. In poor countries, compliance with single drug regimens isn't great a lot of the time due to nonexistent infrastructure for distribution and treatment monitoring-- requiring a cocktail of drugs to deal with drug resistant TB is no different. Additionally, TB-specific hospitals, where they exist, are largely places that people with TB go to die. Their relatives frequently get infected from visiting a TB-infested hospital den, of course.

The rise of XDR-TB (poly drug resistant) means that a growing number of people get a death sentence from an otherwise treatable disease. The suggestions I made in my college report were to invest in healthcare infrastructure and secured involuntary quarantine facilities; the former to help those with MDR-TB and regular TB, and the latter for the rest, who probably can't be helped rationally under utilitarian economics of a poor country. Best to limit exposure to the healthy.

cmdrtaco's screenshot is a great example of how, back in 2002, we hadn't yet learned "just because you can, doesn't mean you should".
Nothing I can think of that isn't primarily intended as edutainment, e.g. Math Blaster, Carmen Sandiego, Oregon Trail. Oh man, and Number Munchers[1]! Those were good around that age. Not many games that were only incidentally very educational that I could handle at that age. I'd expect most of the ones on that list to become accessible to a kid in 1st grade now over the next 2-3 years, though.

I remember loving Microsoft Dinosaurs—a wikipedia search for it redirects to a list including that and a bunch of similar looking titles under the Microsoft Home label—and Explorers of the New World, which even the Internet apparently barely remembers judging from the google results. They'd be OK for a 1st grader but those weren't even games, really.

Main issue is they're all old. A few are hard to run. Some are only available on used CDs. Not sure how they'd keep a modern kid's attention. I gather there are some good games like this on tablets and such, but my kids aren't quite old enough for that stuff yet, so I can't recommend any.

Side note: I'm pretty sure playing Doom, Dark Forces, Wolf3D, and other FPS games with confusing maps from young age is ~20% responsible for my wicked-high scores on spatial reasoning tests (Building lego sets from the instructions can be credited with the other ~80%) so, there's that.

There’s so much stupid in this comment that it’s difficult to process, but I wanna focus on just one statement here: “You're more likely to be shot by a gangbanger than a cop”

I am far more afraid of cops than “gangbangers” (wait are you talking about actual urban violence or pornography?). You can fight back against a mugger; when a cop just randomly attacks you — which happens ALL THE FUCKING TIME — you have no recourse.

ALL THE FUCKING TIME. Just look up “stop resisting arrest” on Youtube and watch videos of cops kicking the everlasting shit and tasering people lying helplessly on the ground.

No, hang on, one more. “Criminals are out of control.” Crime in the United States is at the lowest rate of the past century, it’s been plummeting since the nineties.

But what difference does it make? Even if crime were “out of control,” police exist to enforce the law and protect citizens. They randomly attack citizens all the goddamned time — usually based on race, but not always, ask any white person who showed up to a peaceful demonstration and got maced for his trouble.

This is a separate issue than illegal immigration! Even if you’re a xenophobic asshole (and it sure sounds like it), you can and should be outraged by police violence.

Came here to say the same thing. I mean, what reason would we have to believe that evolution has stopped??? I suppose you can argue that technology has eliminated some evolutionary pressures, but from what I can see, that just moves the goalposts around a bit, it doesn't eliminate them.

Ask HN: With the following experience what could I be making?
I started off teaching my self html, php, JavaScript. Then got into game programming and learned Java. Have tried Python to make a simple Reddit bot. Don't like c or c++ because I learned Java first and they seem strange. I've tried raw WebGL (no framework) and with framework (three.js). Have used MySQL but hate that it's so insecure and I'm forced to use mysqli. Currently interesting in making web apps with node.js as the backend. I've made a todo app with node and express as the framework. I use nginx as my server to reverse proxy to my node app. I use MongoDB for the database. Know some Linux so I can ssh into a VPS and set up my app there. Using foundation 5 as my front end framework. Also know a bit of angularjs. Any ideas of what I could be building? Also have I've used websockets and am currently interested in webrtc.

Same for Rackspace, IBM/Softlayer, and everyone else with a large cloud running Xen.

Linode was actually my failover target for some of those clouds to weather the reboots. They offer both Xen and KVM based instances. If you're still running Xen, you can live migrate your instance to KVM and make all your new Linodes default to KVM via a toggle in your account settings.

Utilities are often heavily regulated, with large fixed costs and legal requirements to serve many customers with the same price structure.

Some of those customers are going to be better served by doing something else. As the price of solar and local storage goes down compared to the legacy cost structure of utilities, it can make more sense for more of those customers to leave.

> It turns all cops into walking surveillance machines

Cops already function as defacto surveillance machines. The bodycam doesn't capture any more than the cop does with his/her own eyes and the cop has the authority to act based on that alone, the bodycam is at least an impartial representation of the cop's (or citizen's) allegations.
The first example reminds me specifications of some types in typed Clojure. Part of the reason it gets complaints is those tricky types.

At least they look like that, comparing to Haskell.

"Rider Bills" are just amendments to bills.

Taking the example given elsewhere in this thread, a farm subsidy bill. If the original bill was to pay farmers 10% of their annual yield (i'm literally making this up), would an amendment that added a 2.5% tax on commodities trading of the same crops be a rider bill, or an amendment?

Communication Through Games
Evolution requires survival of the fittest to still be a thing. If the weak die off faster than the strong, the strong have a better chance of reproducing. Then their superior genes are passed on, etc... However, this is no longer as much the case. People who have weaker immune systems, for example, can take medicine to prevent dying from a (previously fatal) sickness.

Why is there too many people in China? What is the standard to determine the right population?
The latter. If people took responsibility for their actions I believe injustices like forced abortions wouldn't happen as often. I can imagine it's very easy for somebody that is forcing a woman to have an abortion at 8.5 months pregnant to rationalize away what they are doing as upholding the law and that the government is responsible for what is happening.
> The idea that some of the best evolutionary data could come from church archives was both astonishing and exciting.

It really shouldn't be (astonishing, that is). As major social, political and educational structures that were, at least in some cases and locations, largely exempt from the greater political upheavals and wars, they should be considered a first choice to search for a lot of data that has to do with human history.
How high-speed rail “shrinks” Japan
A "job" is when a human being is required to insert their valuable resources of time and talent to produce further valuable resources, some of which go to the human being (lest they starve), some of which go to a capital owner, and some of which go to society at large.

Broadly speaking, when you get the same benefits but are not draining a human being's time and talent in the process, society wins.

The question of how to distribute those wins may be tricky, but it's the type of problem that, broadly speaking, is good to have. Like when you unexpectedly receive a cash bonus, and now you have the probem of paying taxes on it... yes, it's a problem, but it's a good problem to have. And given that I've heard people complain about getting money because then they'll have to pay taxes, as if that causes the whole thing to net negative (it's silly when I say it baldly, of course, but I've heard this so often it's clearly a common cognitive template), it's really quite like that situation. Let's not be so worried about the possibility that someday wealth may be unequally distributed that we prevent it from being created in the first place.
Moolenar's screenshot is 1280x1024, or 5:4.
Evolving yeah, but toward what?

We completely screwed natural selection, so I guess bad genes will be creeping into the population for a long time, things like cancer, malformations and genetic related diseases will be blooming like crazy in the next centuries.

Out of the 1,000+ instances I had running in AWS during that last major reboot -- there were only a handful of hosts affected. Sadly, some of them were the very primary core DBs -- but in general, it was still only a handful.

Luckily, many people also converted to HVM over PV already. IIRC it was largely PV instances in EC2 classic... but I can't be sure.

I understand it's convenience and importance in arrow notation... but it definitely feels like too large a jump! Maybe in another 10 years we'll have the Profunctor-Strong-GArrow-Arrow Proposal to fix up that superclass hierarchy.

It's also worth noting that some significant component of arrow notation would survive eliminating `arr` as well as there being an "internal logic"-style syntax for GArrows I've seen somewhere or another.

This doesn't make sense in a patch-based VCS, where you can at best verify the integrity of individual deltas, but where there isn't a repository state that you can hash (cryptographically or otherwise) to begin with.
Exactly. The phrase in question was "essentially guaranteed of being convinced". Even Vegas gives better odds than 87%.
Echoing others, you may not have any choice in this.

Back in 2007 Certegy had a terrible data breach, an employee, sysadmin or dbadmin, sold info on 3 million people (https://en.wikipedia.org/wiki/Certegy#Consumer_information_c...).

Not all that long after that, pretty clearly based on information gained from Certegy or some other compromise of my most basic checking account information---but bizarrely, not necessarily my name? Something was very wrong in the set of info---a debt collector claimed I'd charged hundreds of dollars to on-line porn sites to my checking account.

Which of course is particularly bizarre, because if it was real, why hadn't they just debited my account in the first place?

So, no debt, but it went into collections, and they didn't give up for more than a year. Can't remember why they gave up, other than that they pretty clearly knew the case was weak, assuming the whole thing wasn't a scam to begin with.

For hard data, it's hard to beat http://gridwatch.templar.co.uk/ - has anyone built an equivalent for their own country?

You can see that although wind is broken out to its own meter, solar is not yet broken out. The effect of solar so far is a small dip in noonday demand. The daily high point is about 6pm at the moment, as the end of the working day overlaps it getting dark here.

From the rest of the graphs you can see gas and coal ramping up and down over the course of the day. Gas is capable of fairly rapid response. At the peak, the pumped storage (Dinorwig) is turned on.

Until rooftop solar pushes daytime net demand below the 4am current demand low, I don't think we need to panic about storage.

The government policy on subsidies is incoherent; subsidies for renewables are being cut, but the Hinkley Point C nuclear deal includes an obligation to buy the power at a price far above market or renewable levels.

Personally I have 3.8kW of panels on my roof. At some point I'll go and have a look at the data logger and see what conclusions to draw.

EU rules UK's 'porn filters' are illegal
I'm literally not surprised by anything in this article. Joomla is a mess (my opinion, doesn't actually matter to my point), written in PHP so whenever a patch is released, you can see exactly what the exploit was. In fact, I'm surprised it's not less than 2 hours.

So obviously, "Patch now!" - although, that's not the prerogative of this site, it's to convince you to purchase their "website antivirus" -- which I still can't work out what it actually does, or where it sits.
I don't find it bothersome but I think it's pretty obvious that where there is a lot of talent you will get a lot of recruiters...
Maybe I'm not clear on the rules. I know that streaming shirtless (as a dude) is not allowed.
I don't think the things they are doing wrong is inherently tied to being a startup or being VC funded, at least from a regulatory point a view. They appear to be skirting existing FDA regulations, and that is the area that regulators will focus on and clamp down in.

> Quantum Physics - Everything is non-local

Not true in the slightest. The Many-Worlds interpretation is local.
In that case Amazon's wording would be pretty disingenuous - "AWS customers' data and instances are not affected by these issues" when the reality is more like "as far as we know nobody exploited this before we patched"?
You are correct that, beyond a point, the effects are substantially nonlinear. Of course, our reactions would also not be static.

My point was not prediction of specific outcomes, but rather to illustrate the tremendous disparity between the two scales - even in a year when we lost an order of magnitude more people to terrorism than is typical.

(You are also correct that there are substantial effects beyond the direct loss of life - but that is true with heart disease as well.)

"The entire country would be in ruins. There would be no more cities"

This is still exaggerating the scale.

If we say 3000 9/11 sized-attacks and 3000 dead in 9/11, that's 9 million people. In that time, our population grew by 50 million.

If we say the 9/11 attacks destroyed 10 million square feet of office space, that's 30 billion - about twice what we added between 2003 and 2012 (per http://www.eia.gov/consumption/commercial/reports/2012/build...), so plausibly about what we've added total in that time.

There may be "no more cities", but it would be due to a response of radical decentralization (probably not a bad move, in that situation) not because the cities were physically destroyed.

10 Tools to Manage a Startup Virtually – Startups and Venture Capital
I dunno, but recently when buying some at the local Walmart, an alert went off and they carded me to see if I was over 18. The guy at the checkout didn't know why but he speculated sniffing of some kind.
you could say we "evolved" medicine.

it's too simple to regard evolution as something that happens merely on an individual level. e.g. it was always possible that the strongest and smartest human will get killed by a group of physically and intellectually weaker people. does that mean we stopped evolving back then? no, we evolved social behavior, like many animals before us, i guess...
I always found it instructive that the WWW conquered the world and not Xanadu. X is a much more elegant, rich environment where hyperlinks are more meaningful and it would have been a better world in many ways - but it needs coordination between both ends of a hyperlink, whereas in the WWW, you write an A tag and you're done.

Turns out that dumb and simple beats smart and complex.
