As the link you provided states, it's called Namespacing.

> A namespace wraps a global system resource in an abstraction thatmakes it appear to the processes within the namespace that they havetheir own isolated instance of the global resource. Changes to theglobal resource are visible to other processes that are members ofthe namespace, but are invisible to other processes. One use ofnamespaces is to implement containers.

Virtualization via hypervisor does a lot more than just namespace isolation.[1]

> The basic idea behind a hypervisor based virtualization is to emulate the underlying physical hardware and create virtual hardware(with your desired resources like processor and memory). And on top of these newly created virtual hardware an operating system is installed. So this type of virtualization is basically operating system agnostic. In other words, you can have a hypervisor running on a windows system create a virtual hardware and can have Linux installed on that virtual hardware, and vice versa.

> So the main basic thing to understand about hypervisor based virtualization is that, everything is done based on a hardware level. Which means if the base operating system (the operating system on the physical server, which has hypervisor running), has to modify anything in the guest operating system(which is running on the virtual hardware created by the hypervisor), it can only modify the hardware resources, and nothing else.

So Fox and Pravda are better because they're worse? Do I have that right?
I live in Quebec where we have no-fault insurance for what you would consider "criminal liability". ie: if somebody accidentally or incidentally hits your car, and you can no longer work for the rest of your life, the state (province) pays. Upside is insurance rate are very low. Downside is license plates (state income) are very high (2-300$ for car plates/year and up to 1200$/year in motorcycle plates).
For car insurance itself, you can still have at fault but it just determines who's insurance pays and who's insurance rates will go up.
I think PayPal has been instrumental in illustrating to people that their money once it is in the paypal system is no longer THEIR money

I had trouble before with paypal holding onto funds for months nearly killing my business, when I contacted the Financial Services Ombudsman, their reply was along the lines of "they are a private limited company in this country, they can do what they want"
I am running Debian 3.2.65 with ext4. How worried do I need to be about this?

I assume/hope that if this was a common occurrence it would have been found much earlier...

Update: Having reread the report, it appears that this may only be a problem in the new 4.0 kernel?

Update2: Nope, not just 4.0 kernels (see below).
Does anyone have experience with Coq and Mizar ( http://wiki.mizar.org/bin/view/Mizar ) and could answer the question of the base for both ?

If Coq can be used with Vladimir Voevodsky's theory of univalent foundations, can Mizar also be based on them as well?

Maybe because it doesn't make sense to copy a lot of model/texture data to/from a slow laptop for processing.
I'm not sure I follow you. What "evidence" are you looking for? By reason and experience, the idiom x = x + 3 is better than x = 3 + x precisely because it puts the x's close together. x += 3 is even better because, as I said before, it helps you avoid typos like x = y + 3.

Another example for C-like languages: Writing "if ( 0 == foo ) ..." is an almost mandatory idiom because it is all too easy to write "if ( foo = 0 ) ..." which the compiler will happily compile into useless code. Programming languages are powerful weapons. Idioms just keep you from shooting yourself in the foot with them.
And the exact same thing could've happened with credit cards.
They develop and provide commercial support for Akka, an actor-based concurrency toolkit (think Erlang) for Java and Scala, and Play, a web application framework for Java and Scala, among other projects. They're also major contributors to Scala itself, which is a multi-paradigm (oo + functional) programming language for the JVM. (I work with their software and the company I work for is a paying customer.)
Author here, these TODOs are just to make my life easier. r.range has some limitations now though.

I'm going for a "wait and see" attitude on this one because I suspect there must be some hidden opportunity to extract wealth from the blockchain that I'm just not smart enough to see, but just by reading the article, it seems like this is another case of "groundbreaking because... blockchain."

FTA: The company will be creating “coloured coins”, appending special information to the blockchain indicating that a particular fraction of a particular bitcoin can be redeemed according to the terms written into it. That coloured coin can then be passed around just like a normal bitcoin, while preserving a record of who owns the asset it is linked to.

Ok. I don't have an inherent dislike for bitcoin. I understand how bitcoin works. I understand the incentives. I've read the whitepaper.
I don't see how decentralization is useful for this task. Why would I want to store asset records on the blockchain? What does this make possible that isn't already possible without the massive computational overhead of a global decentralized ledger? I understand the implications that financial assets can be tagged to colored coins and that those coins can be traded without the need for a third party. I understand that it's all public and that the blockchain's data integrity is fortified through global consensus. Why does this matter? What does this make possible?

I also wonder how the institutions will react when rich investors start getting their colored coins stolen by hackers. Will the NASDAQ honor the value of APPL colored coins that were pilfered from someone's laptop? What about in situations where coins are lost or accidentally sent to the wrong address? Will some random bitcoiner wake up one day to discover that they're a majority shareholder of Microsoft?

As I said, I'll wait and see, because if I was as smart as these finance people then I'd probably have an apartment in the heart of Manhattan to prove it.
America and Americans (myself included) are full of inconsistencies and contradictions, but then I think you'd be hard-pressed to find a country that couldn't be described similarly to some degree.

My point is that I take issue with Americans being painted with a big, wide brush of "compassionless" when there is plenty of evidence to the contrary.

Is there perhaps less compassion or concern (in general) directed towards criminals or individuals who are perceived to have engaged in criminal activities, here in the United States? Probably. But implying that such mindset reveals a lack of compassion in toto is ignorant.
The linked story doesn't even get into the security issues related to ads and phishing. And barely touches on the significant privacy issues.
I also find it extremely misleading when the stores quote statistics such as "over 93 percent of all ios apps have been downloaded every month" as proof that people are finding the apps they want. What they don't disclose is that the majority of these downloads are probably just 1 time downloads by the app creator on their own device.

There's one animation that I think compares it to a matchbox. Except the object is camouflage-colored, for some reason?
One point to note here: OWIN and Katana are two separate components. OWIN is the community-driven underlying abstraction layer which doesn't specify any dependencies; Katana is a Microsoft-driven library of statically typed wrappers around it that completely abstracts it out altogether and leaves you with a bunch of tutorials and blog posts that don't look anything even remotely like the OWIN spec. It's all very confusing.

I wrote a blog post about it a while ago trying to untangle the difference between the two in some detail: http://jamesmckay.net/2014/08/sorting-out-the-confusion-that...

Want to start a company in 2015?
So are you interested in starting a tech company in 2015?

If so, I'd like to share an opportunity with you - I run a private development and creative agency in Toronto. We've worked with several local and international startups and have developed many of their applications from the ground up!

Our team is skilled in the following areas:
AngularJS,
BackBoneJS,
Ruby on Rails,
JQuery,
CSS,
HTML,
RUBY,
Bootstrap,
Various API integrations e.g. Stripe, PayPal, BrainTree, Google+, Facebook, LinkedIn, Twitter etc...
Along with the obvious array of Ruby gems.

With that said, we're looking to take on some more clients, and I would be happy to chat with any serious folks who are looking to develop a new web application.

Feel free to contact me at pblogsltd@gmail.com, and we can setup a Skype call!

Cheers!

An old story - the gangsters of Chicago were eventually caught on tax evasion. There's some real value to this practice - after all, what ethical problem is there in arresting someone for one crime vs another, if they are guilty of both?

Revelations about urban crime and policing in 'Ghettoside'
It's incredibly impressive that WePay has managed to differentiate itself and stay independent in the credit card API / marketplace payments space. Balanced seemed to have dramatically higher mind share and felt compelled to shut down.

I've been asked to explain WePay's place in the market before and have been unable to - I'm not sure if their risk / chargeback protection is what puts them over the top, great BD people, I'm not sure. However, assuming their funding is a sign of progress, they're doing something right despite stiff, direct competition and that's awesome.
Fair enough, but the ones that do have the ability to use language well (HL Mencken, David Simon, Carl Sandberg, Martin Luther King, et al) are some of the most valuable members of society, and I am certainly glad that such people exist.
I never said that his understanding is less important than mine. Simply that I was not impressed by his work, because I have seen much better by same-aged undergrad students. I wasn't comparing him to me, but to other people with similar domain knowledge/experience.
I don't think it's smart to sustain yourself on money from mobile apps considering all of the data published about that recently.

I sell a software production online. The purchase page has a simple credit card payment form, and off the side is a small "PayPal" button an an alternative payment method.

Despite the fact that the PayPal button is tiny compared to the credit card form, a full 2/3 of customers use PayPal to complete the purchase.

That's why people use PayPal, because a large percentage of customers prefer it over credit card payments.

Also, I prefer PayPal disputes because they don't charge a chargeback fee like credit cards.

"Not knowing how an if statement works never stopped me from programming anything, so that would suggest it must have nothing to do with programming."
You have a lot more rights to fight them when fighting a bank. With PayPal you probably agreed to third party arbitration.
"Over-designed and under-implemented"

WCF is one of Microsoft's many examples of this principle. Avoid this, the solution hurts more than the problem.
pFSense and OpenWRT (I have no experience in the others) are safer in that a) when issues are discovered, patches are made quickly and upgrading is simple and b) you can select only the services you want running, thereby reducing your attack surface.
It will have the size of a hockey puck. At the moment we are prototyping so please apologize for not being that precise.

ABP has been whitelisting for less than three years, meaning it supported itself for most of its existence. Anyway, uBlock leapfrogged ABP, which tells me that ABP isn't really being developed too well if a newcomer can do so much better. ABP continues to exist primarily on its name - it's a lot like Bittorrent Inc.

And again, most of the work isn't done by the developers of the ad blocking software.
We don't offer a proprietary ML library or API -- we run arbitrary user code, whatever languages and packages you want to use (Python, R, h2o, dato, compiled C++, etc.). The infrastructure piece is like a private cloud, yes.
I wonder if OpenWRT is also vulnerable or if it's just the stock firmware.

I used to use one of the affected devices (TP-LINK Archer C2), but primarily bought it to run OpenWRT on it. Eventually I got tired of tinkering with it and replaced it with something else, though.
Daily Drawing Practice: Spring 2015 Round Up – Joanna Ciolek
The async/await model gaining traction makes me really sad. I use it all the time and it just seems like a giant hack, a band-aid to hide "scary complexity" from the developers. A typical Microsoft approach to things, but it should stay there.

First issue - the necessity for at least two of each method: "DoSomething" and "DoSomethingAsync". Weak. Now as a library developer, you just doubled your work. Sure, sometimes one method could wrap the other. But it's still weak sauce.

I much prefer the Go model - you only code "sync" API's, and let the consumer of your API wrap it in a go-routine and make it "async" if they wish. Much simpler, better, composable.

Async/await is also gaining traction in Javascript. Really, really sad we still try to avoid concurrent programming and how to do it right vs easy.

I'm not sure how that is an improvement.
That's misleading. Yes, you can pass anything as a message, but you pattern match the message to find the type. I suppose you could typecast the message, but, uh... why would you ever do that?
I guess that makes sense. It does seem like a more exotic solution. Especially considering the amount of different skills that whoever is building such system would need to have.

Maybe in some years we'll see if the Parallela paradigm takes off and then maybe there will be more quants out there capable of using such boards.

Not to be paranoid, but there's always the possibility that some government agency has built >>50% of the mining capacity, just in case they want to take control. And if they're mining with it now (split among pools), this capacity would partially pay for itself. You'd never know they have control until it's too late.
> But people are not being locked up just because they are black,

You're ignoring the fact that black people are more likely than white people to be arrested for minor crime; they're more likely to get prison time for similar crimes; etc.

> or poor.

Ferguson etc showed us that small towns used minor traffic violations as a revenue stream. Someone would have a minor, small, traffic violation and get a fine for it. They would then have to decide between taking time off work to pay he fine (and thus lose their job) or go to pay the fine, if they can pay the fine by the time they have too.

Because many people can't afford to pay the fine they end up in jail.

That's pretty much putting people in jail for being poor, and the US does it a lot.

It's somewhat illegal but you're only downloading content so it's less illegal than a torrent where you're also uploading the content.
Agreed.

I worry that the name change will reflect a change in focus away from type-safety. Which, like someone else commented, is already the case with (some aspects of) Akka and UntypedActors.
Well, here in Germany, maybe europe in general, you can't assume that your customers own a credit card. I like Stripe a lot, but using it as the only payment option wouldn't work for us.

Credit cards have become more common here recently but for a long time it was either Paypal connected to the customers bank account or plain old bank wire transfer. Sure, there are some niche services like Sofortüberweisung, but they never gained the status of Paypal.
Does PayPal even allow selling things like WoW accounts? Otherwise you don't really have a right to complain.
I remember reading years ago that every machine in the building was linked into the render farm.

So the person on the front desk had a dual socket, multi-GB RAM monster of a machine, but only used it for light email/room bookings/contact management. But when render jobs were running, the PC was under 100% load.

I'm not sure it'd work so well with laptops due to the battery life issue, as render jobs are presumably running 24/7. A quick search hasn't turned anything up though...
Oh it doesn't make it easy! It just gives you a chance.
As far as I can see, the "critical" label here is coming from a Debian user submitting a Debian bug report, not from the Debian kernel team or upstream kernel maintainers.

I think HN submissions should have some standards for stories that will create the appearance of "there is a critical problem with software X that lots of people use, and everyone should panic and upgrade" announcements. Having the authors of software X involved in the announcement seems like it would be a good place to start.

(I'm not saying that Josh is mistaken about having been hit by this bug, or was involved in the decision to submit this to HN.)
Linksys has been mostly pretty good and yes the openwrt and dd-wrt software is better.
This is not a race issue. This is an inner city culture problem. Ending the drug war is a first step. But we still have to give these kids something to do. Pay them to go to school.
Thanks for the kind words. (Bill from WePay here)

We keep a relatively low profile, since we focus primarily on marketplaces & platforms with >$10m in annual payment volume and take a pretty deep, enterprise approach with our customers vs focusing on a broadly available, self-service developer platform. One day we hope to get there too, but for now we like to go narrow and deep for the sake of focus and providing a killer customer experience.

As far as product differentiation, we focus on marketplace fraud & risk management above all else. It's a tough problem to solve - most fraud systems are built to protect retailers from bad buyers, but the most insidious fraud risk on marketplaces is from bad sellers. We guarantee our customers against this type of loss while still providing a great overall UX.

Happy to chat more! bill@wepay.com
If a crime is "having drugs" then the war on drugs criminalizes something that maybe shouldn't be criminalized.

If the intent is to help combat drug use then putting a user in prison and ruining his and his family's life doesn't seem like the way to do it. Not to talk about the crime it generates when a business that WILL happen doesn't have any other means to compete than with violence.

There's a great discussion between Glenn Greenwald and former Bush Drug Czar:

Absolute nonsense -- put a black box into each vehicle. They already collect mountains of telemetry, and having that will pretty much ensure indemnification.

Nobody who knows what they are talking about has ever claimed Euclideon's tech isn't real. What those people have said is that A: it isn't revolutionary because B: it's pretty obviously simply an implementation of a well-known technique with C: well known and quite significant limitations that constrain it to a very small useful space which is the reason the many, many people who know and understand the technique quite well tend not to use it for anything and D: not even a shred of evidence that they have overcome the limitations of the technique. And E: as a consequence of A-D the verbiages constantly pumped out by the company is grossly overstated to the point of either just riding the line of fraudulent, or crossing it. Particularly as the constraints of the technology generally precluded it from being useful in the fields they claimed it would be useful in.

Using it for sort of 3D photos of real-life spaces isn't a bad use, and I have no problem believing it's a real application of the tech. However C and D above remain in full force.
Notice that it's still based on 4.2, there are not so many of devices it can run on and even with fully documented and open platforms like GTA04 it's still a lot of work to make it run.

Plus there's absolutely no way to upstream their work, so it's a massive maintenance burden (one of the reasons they're still on 4.2)

AOSP is just what zurn said above - a code drop. If Android was really an open platform, Replicant either wouldn't be needed or Replicant devs would have much less work to do. Openness of Android is great for Chinese vendors making cheap tablets, so they have a ready system to put on them for almost free - but it's not so good as an open platform.

I was as surprised as you likely will be. The exception is with capital punishment. It looks like black people are more likely to get it than others. But otherwise nationwide crime and punishment statistics look mostly fair.
