Hmm, that's not really how these attacks work. When a miner doesn't mine according to the rules, their blocks are invalid and rejected by the network.

edit: Unfortunately you have now given me an opportunity to admit that Excel is probably capable of running Bitcoin-equivalent software, though.... I would prefer not thinking about this.

If sexist statements are simply a matter of opinion than there probably really aren't any at all by some measure or the other....

I believe scientists (aka people who have taken the time to study and learn) should do science. Not anyone with a diverse opinion. There is plenty of room for guidance at the funding and application levels. Which, btw, also require some knowledge and qualification besides being a third rate hack writer who makes sexist statements....

Uninformed opinions are cheap. Knowledge and good thinking skills are rare.
There were definitely blips and long-term appreciation. Here's a paper [1] on housing prices around the world, pretty interesting stuff. I guess my point was, having seen some of these graphs, there is a pretty clear transition in the 90s where the "role" of housing in the economy seems to change (although the graphs in the paper I referenced show the growth starting as early as the 60s, so who knows).

If the target is security sensitive, there's whole classes of errors that are avoided by parser generators.

They are also useful to use while shaping or discovering a syntax. Parser generators will quickly show you where the irregularities are because they will become harder (or impossible) to implement.
We tend to call the simple version of those "mounds". There's a lot of them in the world.

Square pyramids are what you get when you make a mound out of rectangular dressed stone. Making cones or other types of pyramids out of dressed stone is much harder because they demand more complicated shapes.
> Worries about child support aren't a particularly good reason to get married or not get married, because they apply iff you are a parent, regardless of marital status.

Actually, they apply iff you are a parent and not married to the child's custodial parent. Marriage, therefore, has something of a mitigating effect.

Marriage does, however, also potentially have a contrary effect that increases the risk, because of the rebuttable or conclusive (depending on the state) presumption of paternity for children born during the marriage.

If you can pull a great product and get sponsored like Salvatore, sure, you can match Silicon Valley and make a good living even in Italy. But you have no idea of how much lower salaries are over there and how much lower you are considered as a professional if you take a normal dev job.

For that, I have much admiration for Salvatore.

Niall,

I sense that you don't really want an answer to this, you have already made up your mind...

Why is the sticky session requirement a huge devops concern?

From what I understand Mongo sharding shouldn't be hard to implement, but I haven't tried it myself. I spoke to Abigail Watson about it, and she said her first tests with it were promising.

RAM is always a precious resource, so I understand being concerned about it. Are you seeing some absurd usage per client? I am seeing about 350mb processes to handle around 75 connected clients.

Is there a framework or platform that gets the 'last write wins' correct? I seriously doubt that because I doubt you can apply a blanket set of rules for offline support.

I don't think scaling is off-putting, you just need a mongo cluster and then you can add oplog enabled Meteor processes to your pool. I don't see how this is any different than something like Java or Ruby...

The idea of adding Cordova may seem simple or small, but MDG putting it in led me to building my very first mobile app. Prior to trying Cordova and Meteor integration, I usually advised clients it would be easier to just build a responsive design instead of trying to build a native app.

I am sure if you looked at the commits around adding Cordova, it was a little more then just glueing together some CLI tools.

That being said, if Ionic floats your boat, go enjoy it :)

But according to this, all the phone home addresses are generic open proxies that have been well publicised across the Internet and already abused for quite some time. None of the proxies listed appear to be in NK, and (to date) no evidence that NK IP addresses were on the other end of those proxies at the time.

It's a bit like saying "the attackers used malware which made DNS queries via the IP address 8.8.8.8, which has been used by NK in the past" - if anyone were really building a case on that key evidence, they should prepare to be laughed at.
There are few details, so before signing up I'd ask:

* Do you support IPv6 monitoring?

* Do you support testing from multiple locations? If so how do you detect local flaps with peering/routing? (i.e. A site is down from one source, but not the other.)
You have no idea how they obtained whatever evidence they have. The source(s) may very well be classified, in which case they _cannot_ share any of it. NK spys, wire taps, etc. None of this could be disclosed.

I wish I knew too, and Im not trying to convince you to blindly trust them (because I don't either), but you have to at least acknowledge the fact that they may very well have "something to lose".

>I call BS.

And yet your post can be summarized as "I am not aware of the usage of L4 microkernels".

>The "is formally verified" they could not care less, and rightly so, if their other demands are not satisfied...

Except their "other demands" are satisfied. It implements L4, just like every other L4 implementation does. It also happens to be the fastest L4 implementation ever tested. So rather than vague dismissive "calling BS", how about you point out the specific fault in SEL4 that causes people to need to use other L4 implementations instead?
Needs an Xscreensaver demo. :)
But you don't have to see proof, and it is no one's burden to convince you. The US is not trying to prosecute North Korea in court. This isn't an amendments issue. And despite the ridiculous recurring claims, the US is not using this as a context of war.

"NK which wants to be included in the investigation"

It is incredible that people are actually falling for this. North Korea said "let us in on the investigation or we will attack you". Who is going to say yes to this, even if one were so naive as to think the request were truthful (which it most certainly is not). It amazingly achieved its goal, however.

I'd put money the Japanese gov/intel just sets up a virtual TOR in their own cloud and redirect all queries to the non-authenticating whistle blower site to their own completely controlled TOR service/network. It likely will just serve to be a honeypot.

edit: Also, for them to actually create an authenticating service, they'd have to establish their TOR service proxy to route through non-controlled Japanese friendly nations. By proxy, the Japanese are also given the authority of the US, and there are not many places he/she can route it to, or establish a network strong enough to deter Japanese gov./intel from tracking down dissenters.
I really dislike these type of comments. Yes we all like to hate on PayPal. It has questionable business practices and its products aren't necessarily cutting edge as compared to say Stripe. But let's just pause and recognize this http://www.datanyze.com/market-share/payments/paypal-vs-stri...

So there's nothing wrong in creating a business that serves a wildly large number of customers out there. PayPal dominates the market outsides of startups and the valley tech companies, and as such a huge market to build a product or company around.
I think you missed something in your calculations.

Removing 0.1% load from the machine will not result in 0.1% of energy savings, very very far from it if in any at all. And that's not even what we want to calculate. We want the difference with hypothetical alternative in a safer language, which is hard to guess, but is unlikely to be in the same order or two with your calculations.
Ha, I felt the same way. Did you end up buying it?
If you're using Firefox maybe you're using NoScript. It's from Sicily too (http://www.techrepublic.com/blog/it-security/an-interview-wi...).
Tons of people use L4 for their systems, there's billions of devices running some L4 kernel. The question is why are they not switching to SEL4 given that it provides the same thing they are already using, but faster and proven correct.
How does this work responsively? I was initially reading this on my phone, and the first example says the middle item is not allowed to grow so the left and right have been given an equal share so they are sized evenly.

Except on my phone I was seeing the left and middle taking up 50% and the right one being pushed down and taking up 100%.
I'm also sure Shostak is thinking about probabilities. My point was that we shouldn't necessarily think about the probabilities along a presumed straight-line path.

The logic Shostak is using here begins with a sort of reverse-engineering of how humanity made its progress, followed by an implicit presumption that other advanced civilizations will follow the same path, until such time as they advance beyond us (by way of AI). I don't believe we can confidently say that technology has to progress along the path we walked.
If it really was North Korea, wouldn't they need a shedload of help from China?

I mean it is inexpensive to develop an exploit hacking team but they would need training and the only two obvious sources would be China and South Korea and I cannot imagine south korea doing it willingly.

This all reminds me of how in 1993 that TV show seaquest was predicting countries assassinating other "elite hacking teams" - seemed crazy then.
How about something like:

Instead of having an about page why not just remove it and make your contact page a little more personal than just an email link?

After looking over it I really dont think the about page is really going to offer much value to your service. But a more personal contact page would be where I would spend the time.
On the contact page explain that saasymetrics is a startup and that you are trying to solve X problem and you encourage people to get in contact with you.
There is something interesting happening in the media in relation to hackers and I think that is evident by the fact that this article refers to white hats as "anti hackers". To me, that is a deliberate separation that is intended to hide the good that hackers do.
I know about their timber constructions, but I'm pretty sure that some of the things they built that have lasted couldn't have been built with timber, like the aqueducts, the Pantheon or the Colosseum. It's those things I am wondering about.

I love comments about the "anti-hacker community" though the underlying link to marco's blog (as this entire article is just commentary on original source material) http://marcrogers.org/2014/12/21/why-i-still-dont-think-its-... gives his entire opinion.

I dont think its news to most of us here that the NK connection to the hack is circumstantial; Sony's security has been penetrated by non-state actors before, and without a lot of effort from what I can tell.
Yeah, that's pretty much what I mean. We could live on a great deal less than we actually have now, and I mean, we could live quite effectively. The transition would hurt (or perhaps rather, will hurt), but in the end I think we'll all end up surprised by the fact it wasn't harder. Think Y2K here. Probably bigger than that, but in the end, more blip than crash.

Big blip, though. But at the current rate we're headed for that anyhow, regardless.
>But even so, it's still mostly written in C and likely have many of the same pitfalls that all kernels written in C will have

No it won't, that's the point. It is a much stronger guarantee of being without those bugs than using rust would provide.

>because it would have far fewer segfaults and the like

SEL4 can not segfault, that's the point. It isn't fewer, it is zero.

>but clear I was thinking that we can start with a Rust kernel and build on top of that.

Yes, and I am saying if people actually wanted that, they could start with a formally verified kernel that already exists and build on top of that. But they don't.
An IP address associated with a cyber attack, is more like someone stealing your car and using it to hit a bank than someone running through your backyard to escape the cops.

And if someone went through your backyard or your garage while trying to escape from the police, the cops might want to look in your backyard or garage to see if the 2 Kg of heroin he was supposed to carry or the gun he used to shoot at them while fleeing didn't end up there.
I'd read 'anti-hackers' just like someone who was described as 'anti-war'. On the plus side at least they're starting to understand that not all hackers are bad?
If I visit a page hoping for information, and there is a video with no text or other supporting context, I will close the tab immediately. If there is a video and something to read, I will make sure the video is not playing and then read the text. Images are no problem.
North Korea could produce evidence definitely proving they had nothing to with it and it would still be dismissed as propaganda. The number of people who believe that north Koreans are all brainwashed, and yet will accept unquestioningly all of this crap made up about NK is astounding.

Do people /honestly/ think that they have to have haircuts "in line with a socialist lifestyle"? Even after their national TV network reported that it was slander?

Regardless of what you think about NK, it's a product of the circumstances that led to its creation, and it's a bit rich for the American government in particular to say these kinds of things about NK.
I'm absolutley outraged, offended, and flabbergasted of the use of "he".
I wouldn't go that far. It doesn't take away anything major (like the start menu) but it does seem slow and buggy. Perhaps it's Windows ME?
Although I don't like to believe everything the government says (and I have no idea whether they are correct or not in this situation) please stop turning HN into conspiracy theory central. The last week has seen a few of these 'experts debunk North Korea theory' on the front page every day. Due to the fact the FBI has withheld some of their evidence from the public we won't know. Unless we can see all of the evidence we won't know their reasoning. If the US was threatening war with NK over this I would be much more worried and glad to see these posts but considering the only action they are even considering is putting NK on a 'terrorism list' they probably aren't all that confident in their own evidence never mind the stuff they've made public.

I guess my point is please stop posting this stuff. Whenever anything newsworthy happens the 'experts' (in any field) come out in force debunking stuff when they don't have all the evidence. It drives me nuts. I know this is a community and if people find it interesting it'll end up on the front page - that's fine, it's just getting a little annoying.

Never attribute to malice what can be just as easily attributed to stupidity.

Largely outside of the hacker community, the true definition of hacker is lost. If you only look at popular culture there aren't a lot of in-roads to the correct definition of hacking. Therefore how would the average person know?

Ask HN: How well does your small company/agency do with social media?
If you work for a small company or agency, or own one, how would you grade your social media presence? Have you tried any content curation tools?

If you use a tool like Buffer, does everyone contribute links?? Is it managed by the company at all, or do they trust you to just post?

In my experience, I've heard "We know we should be doing more, but we're so busy" from nearly every company I've talked to, even those that manage social media for other people. Everyone is too busy working, to contribute to the company blog/twitter/facebook page (unless it's someone's dedicated job to do so).

I'm trying to gauge if this is as common a problem as I think it is. Thanks for any thoughts or feedback!

I wouldn't be too concerned about this religion catching on or turning into a cult of any significance...

The founder appears a bit too eccentric to appeal to very many of those with a religious bent. It seems more like a personal assembly of elements from the founders past coupled with things they found value in. So great for them and a very small number of others.

After all, it's not the first time a successful business person dabbled in starting a religion. Dr. Kellogg of "They'rrrr Grrreat!" cornflakes fame for instance (as a side effect Corn Flakes can apparently help cure masturbation also.... http://mentalfloss.com/article/32042/corn-flakes-were-invent...).

>If it took a huge development effort for SEL4 to get to the state it is currently in, doesn't that make it unlikely anyone can easier go in and change thinks or add features?

No. Most of the huge development was in developing proofs for C. The developers now find that development is easier than just using C directly. The process is to write it in a high level specification language, then when you're done messing around and know you have it how you want it, translate it to C by hand and the proofs will tell you that you did it right (or wrong).

>It doesn't seem to have the feature you expect from kernels these days.

It has exactly the features we expect from kernels these days. The features we do not expect from kernels these days but did expect from them 30 years ago are available in a library where they belong.

>A Rust based kernel could be a *nix

So can any L4. Why would "start from absolutely nothing" be easier than "start from an existing microkernel"?
