But URL shorteners aren't really that much more fragile than non-shortened URLs. Sure, the scale of the problem could be larger, but URLs go away all the time. I doubt even a small fraction of the shortened URLs that would go away as a result of the shortening service going offline would have out-lived the shortening service anyway.

And how do additional layers create more fragility, when the most fundamental layers (e.g. ISP infrastructure, DNS) are just as vulnerable to attack as the application frameworks implemented on top of them?
Wow, arihelgason, looks like you guys are doing great work!

Nice name, cool web site, pricing & features right up front.

Only problem, the video crashed my browser, and I couldn't find screen shots any other way.

Keep up the good work.
This headline is over-inflamatory, and the article is pretty far off the mark.

Twitter is very good to developers. The only cases where there are altercations are when people use the word "Twitter" in their service's name. That's defending their trademark - something all companies need to do if they want to keep those trademarks.

Twitter's not headed for big trouble at all - or at least, that trouble will have nothing to do with the problems mentioned in the article. The main trouble on Twitter's road, imho, is the big battle they're having with Facebook. There'll probably only be one winner in that one.
That's a good point, and since the OP uses the word 'app' for both products I doubt that there would be enough distance to avoid confusion.

Registering a trademark in bad faith is not going to end well.
My assumption would be that the main difference is the formal proof, and whatever changes were necessary in order to permit formal verification (i.e. they may have changed behaviour in order to make the implementation actually meet the abstract specification).

But I agree it would be very interesting to find out what the differences are, and whether substantial changes were required in order to do this kind of formal verification.
Silverlight has an open implementation which Microsoft has assisted with. I'm not sure how far behind the official releases it lags, but it has an open implementation.

For some things, using RIA frameworks eases development massively and lets you do stuff which would take ages to do in plain HTML/JS. Google themselves said Google Wave took around 2 years to make. Do you think it would have taken that much time using non-HTML technology?

I'm not saying sticking to plain HTML/JS isn't admirable, but sometimes it's just not very practical.

Also in this case it isn't required, so your potential scenario about being "stuck" with it doesn't really apply.in any meaningful way. In fact they have done just as you said, but given people the option to use a plugin to make things better. It degrades by default, which is helluva lot better than most sites out there.

I don't see you cursing Flash in the same way as you do Silverlight in. What makes Adobe Flash any better?
In the US it will probably have to be pushed forward by the federal government. Once the technology is good enough to significantly cut crash death rates then it becomes a public health issue. I expect they will establish some sort of certification program for automatically driven cars. And manufacturers will receive liability protection for certified products.
If your site becomes even marginally successful it is almost inevitable that some jerkwad will register a .info or .cc version of your domain to try and take advantage. When you consider that a .info domain is around $1 it's probably worth your time to just register it now.
I've been using Arch as my primary desktop for a couple years, after switching from Gentoo. It reminds me a lot of the early days of Gentoo, the wiki is great, and the community is helpful. There's been very little breakage from their rolling updates, and when there is, there's usually a warning on the news page about how to fix it, before the update is even released.
'In fact 26% of survey respondents said they didn't care about Netbook OS as long as it "got them on the web."'

You seem to understate your case.

In addition to that 26%, you have 21% that prefers Linux, and 7% who will take Linux if the price of the computer is $50 less. That sums to %54.

I think the big question, though, is how many of those will change their mind and return the computer once they try to install a program that only runs on Windows. Do they honestly know what they are getting into when they say they "don't care" about the OS? Maybe they don't care about the OS, but do care about a particular program they want to run, but don't understand that choice of OS might prevent them from running that program.
I'm fairly sure that if Jesus Christ would walk the earth today that he would not be one to make it very high in the ranks of the various churches in his name.

I don't doubt your word that he was an enlightened man but for some reason those tend to get wielded out at a pretty early stage, they'd upset too many holy applecarts.
Thanks to who ever drudged this article up (it's 3+ years old!). I had just gotten rid of that nervous twitch induced by any mention of "enterprise sales". :)

We tried, and it didn't work for us. Customers reverted back to normal behavior, as did we. Plus, investors (with no exception) all told us it wouldn't work, that customers were going to continue buying enterprise software just as they had been.
Having been there and back again I laugh at the elitism on this page now.

"Arch doesn't offer such a facility as it goes against TheArchWay. SUSE, therefore, is widely regarded as more appropriate for less-experienced users, or those who want a more GUI-driven environment, autoconfiguration and expected functionality out of the box. "

Such an elegant way of saying SUSE IS 4 teh noobz and i use arch kuz i'm hardcore.

Having been there and back again I find myself on FC, because it's stable. I know that I can update the fucking thing whenever, or not even update for a year and it won't fuck up my install. Unlike Arch which if you don't update for 1-3 month's you're guaranteed a fuckup because you missed 2 critical updates and there's no way to get them unless you feel like manually finding the actual packages and installing them.

That page misses an important aspect, Arch sucks for stability, programming, and people who hate typing pacman -Syu every damn day. Arguably stability and programming are finer points for the SUSE distro because, it's got a plethora of development packages which are installable at various versions (yast/zypper is a bit of a bitch about this though), as well as the fact that SUSE handles concurrent versions way better than Arch.

"Fedora has a scheduled release cycle. Arch is a rolling-release system. The Arch design approach is geared more toward lightweight elegance and minimalism rather than automation/autoconfiguration."

I also love this perl of wisdom, no it's not. I can get a minimal FC11 install, or I can install CentOS and get the same damn minimalism and elegance and lightweightness. How do you judge how lightweight a distro is? I can remove every component from fedora and suse. I don't need their gui tools installed, nor do I need their commandline-ncurses tools installed. If Fedora decided to support kmod then it'd have more modular packages than Arch, so what is this mythical lightweightness? Is Gentoo more light weight than Arch? Or Is the opposite true, because Gentoo's ebuild directory can span anywhere from 700mb (generous) to 2 gb.

Here's the bottom line, most OS comparison is FUD. In most distros moving the ease of use up just makes the window of use bigger (a more inclusive user base, ie people who only use the gui or people who only use the cli or a mix).

Also I enjoyed the fact that Arch pretty much says, we break patent law freely because we don't have a backing company who one can get money out of with a lawsuit:

"Fedora famously doesn't attempt to support the MP3 media format due to perceived patent issues. Arch is more lenient in its disposition toward MP3 and other media."

Maybe I'm jaded from all the "ZOMG ARCH LINUX" crap on /r/linux, but Arch isn't as 'teh awesome' as people make it out to be. In fact when you use x64-bit distro all the speed ups (some more than others) that Arch used to tout with i686 packages disappear.

Without actually being an actuary, and having access to the raw data, it's rather hard to tell IMHO whether the rate adjustments are really sufficient to cover the risk. Since risky customers are "pay big now, maybe payout big later" - and young customers get older and more experienced - it seems to me that there may be a human tendency to slightly underprice the risk of customers who pay large premia.

The analogous situation with health insurance, of course, is even more deeply skewed. Insurance companies love having healthy young people on their plans because they almost never have to pay out - young healthy people overpay by quite a bit on health insurance.

Et tu, Hacker News?

The political pieces on HN are starting to overwhelm the technical articles. Isn't there enough of this on Reddit?
For what it's worth any of the Linux/GNU or BSD's will run on older hardware; provided you don't go overboard with X. If you forgo Gnome or KDE in favor of FVWM2 or XFCE the system will run very well on less than 256Megs of ram.

Unfortunately, if you are forced to run Firefox the system resources immediately become a problem. Seamonkey is a viable alternative, but is dated. Chrome may be the way to go, but that is yet to be proven.

Can you say what you tried and what sort of response you had? Was it pricing model, sales approach or transparency? Was your product aligned with your marketing and sales approach (ie more like consumer-grade software which is a bit shiny and nice to use with simple things being easy and hard things being possible) or the grey-clunky-and-feature-rich traditional sort?

Were you doing SaaS (like the World on a Hangar guys) or more traditional software-on-a-dedicated-box-or-three?

I don't think it's intentional. But, I think it would've been more rhetorically graceful to just have alluded to the cave allegory without then saying, "Look, I just referred to the cave allegory!"
Yes, there's plenty of this on Reddit. That's why I used my 'flag' power to flag this article. This article bugs me for two reasons:

1. It's about a non-technical political topic

2. I am British and care very little about the internal political arguments in the US concerning their health care system.
Loud motorcycles are one of my pet peeves. I have never been able to figure out why someone would want to make their motorcycle as loud as possible. Don't they realize how rude it is to every single house, pedestrian, etc. they pass? When I see one I immediately project a complete a-hole personallity onto that person, because I assume he really doesn't care about anyone but himself.
"I am British and care very little about the internal political arguments in the US concerning their health care system."

Amen Brother!

Political articles should be (imho) shut down very fast. The "flag and wait for a moderator" tactic doesn't seem to be working as well as it used to.
If a URL shortener goes down - it's likely that all of the enabled URLs go down as well. I don't think we've had a system like that before. If bit.ly went down - half of Twitter would become meaningless.

A DNS or ISP disruption can usually be more localized. I would argue that it's much easier to disrupt a Twitter or a Facebook than it would to take down multiple DNS servers or multiple ISPs. It would take less resrouces and time to create a global disruption by taking down Twitter than it would to take down an ISP.
You can write the equation of a plane in R^3 as A x1 + B x2 + C x3 + D = 0.

So, in this case, we have (A,B,C) equal to (1,1,1), and D=0. (A,B,C) is the normal to the plane, and D is the perpendicular distance between the plane, and the origin.

So, x1 + x2 + x3 = 0 defines a plane that passes through the origin (D=0), with normal vector (1,1,1) and of course (-1,-1,-1), and (2,2,2) etc. So it's a "diagonalish" plane that passes through the origin and "faces" (1,1,1).

I can't believe that you've actually used Arch. I had one server here that hadn't been updated in over a year, and `pacman -Syu` worked perfectly, no breakage at all.

As for development, its much better than debian- or redhat-based distros, because you don't ever have to install any -dev (or is it -devel?) packages, or go hunt down someone else's repo, because the version of a package you're using is obsolete and missing a feature you need, and won't be updated in mainline for another 4 months, if they even do it then.
Not so sure... I use twitter on my smart phone (IPhone) all the time.

"How's that an amazing prediction?"

Hyperbole, but amazing in the sense that it's very different from the kinds of things "everyone" was saying in 1996. What he said are very much the things "everyone" is saying now.

So, maybe or maybe not great prediction of what will be happening 100 years from 1996. But an excellent prediction of the 2009 zeitgeist.
What is the difference?

I disagree, I don't know many people who appear to introspect at all. I read that and think that your concept of meditation and my concept of introspection are probably more similar than our ideas of meditation.

[edit: Honest question I am pointing out that the parent might not disagree with those who tout introspection, as they may share semantics for different words.]

Dick Kemmerer always talks about how he formally verified the UCLA Unix security kernel in the 1970s, together with Bruce Walker and Gerald Popek. See <a href="http://dx.doi.org/10.1145/358818.358825>their 1980 paper</a>. How is the new work different?
Set this up with some guys in my company and we're giving it a try today. So far, after going through the interface quite a bit, I decided that it's kind of confusion to reason about who is going to be called when. For example, you have timeouts for escalation and timeouts for consecutive notifications - at what point in your notification chain for a specific user does the escalation happen? Is it only after all types of contact have been exhausted? Or will secondary on-call be notified after the admin-settable X minutes (default 30) no matter what primary does?
"The things you own, end up owning you" is the actual quote. I agree that there is a lot of truth to the notion. The more you own, the less mobile you are.
There used to be this checklist floating around with reasons why ad-hoc spam fighting plans don't work, pre-set to just check off the options instead of having to go through a laborious explanation why this idea won't work...

It has some application here.

To me this looks more like Yahoo is looking for additional revenue streams. It starts off with a cent for charity, we'll see where it leads.
"The 'flag' and wait for a moderator doesn't seem to be working as well as it used to."

How can we judge how well the system is working when we have no direct insight into it? Perhaps a moderator reviewed the post and found it to be of merit?
Do you mean, what are eigenvalues used for?

I found this to be an incredibly clear and simple description of what eigenvalues are. I completely missed the point in University. I agree that it was missing a discussion of what they're used for.

You might also want to look at the eigenvalue section of the paper "An Introduction to the Conjugate Gradient Method without the Agonizing Pain" http://www.cs.cmu.edu/~quake-papers/painless-conjugate-gradi...
The article has little to do with politics and the subject which is the economics of health care is well thought out and presented.

Although it refers to the US health care system, the narrative applies to health care delivery in general and is applicable to other countries.

You are right that it is non-technical, but it is of a higher quality and more intellectually satisfying than countless other submissions here. Presumably you also have flagged Signaling and Indian Higher Education though I'm not sure whether your nationality would make that more appealing to you.
"But the inequities in living standards and expectations that makes outsourcing practical currently is steadily being eradicated by the gradual improvement in economic conditions which outsourcing itself helps to make possible."

In effect, it is an arbitrage opportunity where you have a large number of well educated people with a low standard of living, combined with cost of living differences compared to western countries.

Certainly, over the next 100 years such arbitrage opportunities should abate, as people around the world with valued skills have similar standards and costs of living, and thus demand similar wages. We seem to be seeing the beginnings of that process already.
Why do you think you're good at math, when confronted with evidence to the contrary? :)

Is there something specific about the parent post that you don't understand that I can try to explain?
I kinda wish Hacker News would skip the political articles. There are plenty of technical things about health care to cover (e.g. databases for health, clinical trials, input cost reduction).

That being said, I lived under US government health care for a goodly chunk of my life (IHS), and until they fix that, they really have no biz working on anything else.
...and under what circumstances do people pay increasingly less for an increasingly improved product?

The free market!

I agree that there needs to be more direct competition for health care dollars.
"Presumably you also have flagged Signaling and Indian Higher Education though I'm not sure whether your nationality would make that more appealing to you."

One wrong doesn't justify another. But sure, flagged that too. I don't vote up or down based on "nationality". An inappropriate (for HN) article (subjective judgment to be sure) is surprisingly nationality independent.
Amazing talk.

>I can't believe that you've actually used Arch. I had one server here that hadn't been updated in over a year, and `pacman -Syu` worked perfectly, no breakage at all.

Desktop packages are way more finicky, obviously you didn't use it when they switched from devfs to udev (Between 0.7 and 0.8 releases, I've used it on-n-off for 5+ mo at a time since 0.4) as other major infrastructure overhauls like the PAM overhaul 3. Then again it wasn't cool to use arch at that time.

Since Judd Left the team the releases have gotten a bit lazier, they used to come out every 4 months now it's every year if that.

>As for development, its much better than debian- or redhat-based distros, because you don't ever have to install any -dev (or is it -devel?) packages, or go hunt down someone else's repo, because the version of a package you're using is obsolete and missing a feature you need, and won't be updated in mainline for another 4 months, if they even do it then.

Enjoy working on something moderately complex then, when it automatically updates it for you it'll fuck up your entire code base, so this happens several times a year and you're fucked. So unless you want to do maintenance as you're trying to actually code something rolling release isn't for you unless you like pulling hair. Not only that but culling of features happens much more than addition.

Also your lack of understanding of -dev packages shows you've never really used other distros, SuSE, Fedora, and Debian support group installations of packages such as development packages, development tools, IDE's etc, as well as wildcards in their package managers. So that's a very very moot point.

Not only that but SUSE which is designed with the programmer in mind has several different repos which contain different versions and the most up to date versions of packages.

Oh and by the way, that whole ROlling vs Staged release thing only shows a difference when major architecture is overhauled the lines in reality between those two release styles are blurring, especially with the expansion of OSS and people who work with it. Example: FC11 has kde 4.3 in updates-testing (not rawhide), it originally shipped with 4.2.2, and right now 4.2.4-rsomething is stable. Also Arch isn't as bleeding edge as it lets on some updates have been withheld for months because the developers are too lazy to recompile stuff.

Oh and if you don't have a package you do what you do in Arch, you either make a spec file for it and compile it yourself or go to 3rd party repos (Arch has like 1 actual 3rd party repo I think, unlike the 5-6 for Fedora).
If anyone releases a killer feature then Twitter can just match it. But then again it may not all be about how many features an app has but the quality of features.
