QEMU (short for "Quick EMUlator") is a free and open-source hosted hypervisor that performs hardware virtualization.
QEMU is a hosted virtual machine monitor: It emulates central processing units through dynamic binary translation and provides a set of device models, enabling it to run a variety of unmodified guest operating systems. It also provides an accelerated mode for supporting a mixture of binary translation (for kernel code) and native execution (for user code), in the same fashion as VMware Workstation and VirtualBox do. QEMU can also be used purely for CPU emulation for user-level processes, allowing applications compiled for one architecture to be run on another.

Economies don't just disappear, they change - they maybe don't grow as quickly, maybe they contract a bit (some areas would be worse off than others if they don't have local sustainable practices). War shifts activity towards military-related creation which I don't agree with, though letting that little irritation grow into a rash is the wrong approach - because that rash gains "power" or rather the ability to control more and be more free than could be if you were applying an ointment to it. The fear that has been injected to people relating to the "economy is going to collapse" only has power because capitalism currently causes a false state of scarcity. We have the resources to feed and shelter everyone, giving them the time to live life, to learn, etc.. Once we solve this false scarcity then that fear will be alleviated and people who have control issues and who are unkind can be limited by societies of how much influence and control of resources they have.

Thank you for taking a stand on this and making it policy.

Back when I got enough karma to be able to flag submissions, I used it on linkbait submissions, but it never had any effect... and I quickly lost my flagging privilege.

I hope this pattern of finding more authoratative and higher quality sources continues. It can only benefit HN.
I agree with this. I have a few DO accounts, a Linode and a few BuyVM accounts. The Linode is what I use for all of my "serious" production stuff, but I love the LEBs to play.

That said, I do think the performance of DO is quite good. It reminds me of Slicehost back in the day.

The BuyVM guys are just the best people ever, and I mostly maintain play boxes there just b/c I can get away with stuff there that might not fly at DO or Linode.
I ran Arch on my laptop for a couple years until switching to Ubuntu Server 14.04 a couple months ago. It more closely matches my dev servers taht run 12.04, and using i3 I hardly notice a difference day to day.
When anyone ever asks me that I say: "why not". Then I tell them "do me a favor and lets skips the bullshit questions". Then I start talking to them about things that actually matter like: How much profit we've made, what our run rate is and what can happen. The bottom line is, when you actually make a profit, at least a couple of thousand no one is gonna ask you those useless questions.
This post set off the voting ring detector. We sometimes waive that penalty for good original work. In this case, though, I think it would be better to wait until the product is ready for people to try, not just sign up for. Then it will make a good Show HN post, and those are widely agreed to be the best things on Hacker News.
What's the deal with this "Ubuntu Browser" being set as the default?

I feel like Canonical has a serious Not Invented Here problem, where they keep trying to re-invent the wheel by writing their own desktop environment, window manager, browser, startup system, etc.
Very impressed.

This coalesces a lot of different ideas together into what seems to be a really tight package to solve hard problems. In looking around at what most companies are doing, even startupy types, architectures are becoming more distributed and a (hopefully) solid tool for discovery and configuration seems like a big step in the right direction.
How did you upgrade? I can't find any upgrade link, even after switching to a 64-bit kernel.
Very interesting. I half to imagine most of the crowd doesn't understand the rules, or is intentionally trying to throw the game. Many of the moves that I saw happening were exactly the wrong move to make.

Here are rules and strategy as discussed here prior: https://news.ycombinator.com/item?id=5898506
> But I don't see any indication that DO treats servers as disposable or fungible whereas Linode doesn't.

I'm not sure "disposable" is a good word to describe DO's approach. We do know that they cram a lot more people per host machine, though. That may be where the "treat VMs like cattle" statement was getting at.

You need only fire up a few instances of comparable type, get some CPU load, and watch some basic metrics to determine this for yourself.
It might be interesting if they could add some kind of geofencing feature to it. So you could have it automatically be enabled when you're hanging out at the bar you go to when you want to see friends, but be disabled otherwise. It's good that they let you turn it on and off whenever you want, but having to do so manually seems like a chore that will cause me to just leave it off all the time.
I created a similar service a while back at http://www.nearbyfriends.com. Here is a video describing the launch: http://vimeo.com/15039067. I later added proximity alerts so you could see when your Facebook friends check in near you. Funny to see Facebook launch a similar "Nearby Friends" three years later.
I dunno man, the SQLAlchemy expression interface is pretty hard to work with and the documentation isn't all that great either.
Interesting. That's helpful. For some reason I wasn't seeing that behavior on my ancient FF that I use at work. Thanks!
It depends on the task. If your Rails app hits the database a lot, memory availability and disk speed will matter a lot, which favors the new Linode style. If your app just does one small query per page and then gets on with its work, then probably CPU is your most important thing (since most of your time will be spent on app logic, runtime housekeeping and rendering templates).
Should something be happening with the bar data payload in the HTTP kv example? Or is the value encoded for some reason?
[OpenSSL] Do not feed private key information to the random subsystem as entropy
QEMU lets you emulate ARM architecture on x86 for example, which is not possible with VirtualBox.

I've played with a Raspbian image running on QEMU hosted on Windows 7 a few months ago.
Do you seriously think that wouldn't just turn into a chatroulette insta-dong service?
I'm sure that the vendor will gladly return the money paid for it.
A bit of goodwill generation after the whole Condoleeza thing.
The skill isn't the hard part. The hard part is getting the money to make the plant.

The problem is that molecular biology often doesn't work. So it takes lots of time and experiments to get it right. Which costs money. Lots of money.
Not bad, I think this will end games of phone tag where people mention vague landmarks for friends at large events.

Due to Facebook's usage, I think this will take off. No need to convince friends unsuccessfully to install another app.
Is the human capital pool really that tight in the Valley?
Here's my theory on it. The main problem is that companies only use one method for determining pay: comps. That's it. They just look around at peer companies and pick a number that's average or higher. It's a perpetual arms race with things only moving in one direction. One guy gets a raise? Effectively everyone does, too, because the median/mean just went up. After 30 years, the compounding effect of this becomes unimaginable.

But that's only half the problem, the other half is that using comps with respect the executive pay is boundless in practice. Think of it compared to housing prices. Home prices rely heavily on comps to help determine the market, but real prices can only go so high because there's only so much debt burden buyers can accept. Prices are effectively capped (in the short-run) by income. This is not the case with companies, particularly bigger, stable companies that are more-or-less on autopilot. Technically, the "market can bear" paying the management billions since these companies are large and profitable. It's just a skimming operation.

What we have now is people, oftentimes interchangeable and generic people (and sometimes even downright morons) making unspendable fortunes for simply showing up to work. Someone else built this thing. Other investors provided the capital. And somehow, you get Fuck-You money. There's no incentive alignment anymore.
In addition to KVM use couradical points out, it's also used in the Bitblaze BAP tool's TEMU component[1], which does dynamic analysis (including taint tracking) over x86 programs and kernels.

Where exactly are they innovating?
The VirtualBox virtualization drivers have serious issues. They're written so poorly that they're notorious for causing kernel panics on linux. The kernel devs consider your kernel tainted if you load the virtualbox modules.

I've crashed so hard using virtualbox that I didn't even get a kernel panic, just a box that wouldn't even respond to alt+sysrq.

On top of this, I personally prefer QEMU because it doesn't come with a clunky GUI.
I recently became aware of Picturelife, and the Everpix shutdown prompts me to ask: is Picturelife profitable?

Everpix looked really great, and I was very close to signing up, but then they shut down. I'm glad I didn't just to see them shut down.

I know you say you wouldn't roll over so easily (which is great!) but it ultimately comes down to whether you have a viable business, which Everpix clearly did not. If I sign up for Picturelife, will it survive without outside investment or some miracle? Is it on a stable trajectory?

Thanks for any insight you can provide. Your service looks great :)
Maybe because renting forever is ultimately cheaper than buying a house, especially if you aren't able to save at a rate that you can buy a house at a reasonable time.
I guess what I'm really getting at is entrepreneurs start companies to make money period, they don't start companies for fun or any other crap you hear. When I say: "lets skip the bullshit questions" I guess it lets them know I value my time and the reason I started a company was to make money or else I'd be into non-profits. People don't accidentally get paid in startups they know they're gonna get paid doing something and the successful ones don't just charge enough to make a modest living either.
Virt-manager uses QEMU and I think it is pretty good, and much faster than Virtualbox. If you wish to use a desktop though, you should configure the video card of VM manually, its performance is not that good, but if you really want to use desktop VM, I suggest VMWare, I found the interaction much faster, but Virtualbox is pretty good to.

In short, QEMU with KVM is way faster, for servers, non-gui interactions.
Do that and they will merge into low density sprawl with no space left unpaved. We desperately need to build up.
Except even then Python 3.4's bundled virtualenv module is still broken. The omission of the ensurepip module isn't an inconvenience, it breaks Python 3.4 functionality.
This essay was written in 1958, before the 'Invisible Hand' was replaced by the Coase theorem which actually explains why externalities don't happen in free markets as often as you would think they would (instead of just observing it).

"It does take a mastermind to get close to any kind of optimal solution in many cases" isn't correct. Relaxing the optimality constraint doesn't actually make central planning any easier, difficulty is dominated by the worse-than-cubic scaling on the number of moving parts of the system (and look at how complex even pencil manufacturing is).

Nations actually tried this, a whole lot of useful math for optimization problems was discovered, but economic optimization is still algorithmically intractable.
Font color: The difference between #333 and #444 is tremendous. #333 against a white background appears black on white. While perhaps you convey a 'weaker' message, it's easier to read.

Editing to add:

The columns Increase Conversions and Understand Your Funnel should be swapped.

You identify two segments of work at the very bottom of the page (one week and two weeks) but in sum it reads like you're just a guy who comes in and sets up GA. Rather than obfuscate this, make it more transparent and up front: I'm a guy who knows GA and I'll guarantee that I'm going to find value in what you're not optimized for, let alone tracking.

Hope this helps and best of luck!
It runs non-x86 binaries.
Should also point out:

The category ‘‘drug-induced causes’’
includes not only deaths from dependent and nondependent use of
drugs (legal and illegal use), but also poisoning from medically
prescribed and other drugs. It excludes accidents, homicides, and
other causes indirectly related to drug use. Also excluded are
newborn deaths due to mother’s drug use. (For drug-induced causes,
see Technical notes.) Between 1997 and 1998 the age-adjusted death
rate for drug-induced causes increased 5 percent from 5.6 deaths per
100,000 U.S. standard population to 5.9, the highest it has been since
at least 1979.

And doing a little searching for number of deaths from prescribed medications:

In 2010, there were 38,329 drug overdose deaths in the United States;
most (22 134; 57.7%) involved pharmaceuticals; 9429 (24.6%) involved
only unspecified drugs. Of the pharmaceutical-related overdose deaths, 16,451
(74.3%) were unintentional, 3780 (17.1%) were suicides, and 1868 (8.4%)
were of undetermined intent. Opioids (16,651; 75.2%), benzodiazepines (6497; 29.4%),
antidepressants (3889; 17.6%), and antiepileptic and antiparkinsonism drugs
(1717; 7.8%) were the pharmaceuticals (alone or in combination with
other drugs) most commonly involved in pharmaceutical overdose deaths.
Among overdose deaths involving opioid analgesics, the pharmaceuticals
most often also involved in these deaths were benzodiazepines (5017; 30.1%),
antidepressants (2239; 13.4%), antiepileptic and antiparkinsonism drugs (1125;
6.8%), and antipsychotics and neuroleptics (783; 4.7%)." -

I think the "drugs kill more people than guns" statement in the slide show is a little disingenuous because "drug deaths" implies "illegal drugs" and not "your doctor gave you some shit that killed you". Also, I find it hard to believe that that number starting in, what, the late 70s? is anywhere near accurate. I'll ask you this: do you think more or fewer people were using dangerous drugs in the 70s than today? During disco, coke, free sex, and a general environment of nihilism? My guess is same or less, not the quite significant growth suggested in the slideshow.
It was nice of Microsoft to admit that their customers are moving to Linux:

"We’ve been working with customers and partners on the migration from Windows XP since we announced in September 2007 that support for Windows XP would end on April 8. 2014. As part of this effort, we’ve made custom support more affordable so large enterprise organizations could have temporary support in place while they migrate to a more modern and secure operating system."

Read the details of the hack. Impressive trick.
I'm interested in this as well. Working on tooling to make this a more efficient process is something that I daydream about often, so it would be interesting to hear some perspectives.

Do you generate tags and hop around functions as you discover them? Do you do a high level overview of the important bits first, and then dive in later? I am sure it is different for everyone, but would still be interested to read about others approaches.

I've had this idea for awhile about bringing up a project in a methodical way in its source control history, and adding new features in a similar manner, so that it would be easier to introduce a codebase to those starting out in it. The problem with lots of large codebases is that as time goes on, configuration details or special cases are added on that obscure the meat of the program. If it were trivial to see the early version, and its evolution, it would be easy to pick out the mental model of what the code actually does.

Very cool tool, but I wish this was explained better. Your tagline should read:

"Build your newsletter as you browse the web" or something to that effect. Another might be "Build your newsletter in minutes as you browse the web".

Somewhere after that should be an easy to understand explanation of how you fulfill the value prop. Right now there is a big gap between your opinion of how long newsletters should take "should take minutes..." and how a person could quickly build a newsletter.

I will need this tool soon, but it took me a while to understand what service you were providing.

Sorry to seem overtly critical, but startup copywriting is always frustratingly opaque to me.
And I would imagine that is very much by design. DO's model is to scale as much as possible -- they want to be all over the place and they have the funding to make those sorts of changes.

As a more established provider, Linode has to decide if adding more customers would be worth the incremental support costs. Given Linode's reputation for support, adding a bunch of LEB customers who aren't likely to renew at the same rates as people who pay more money - and are also likely to have more support requests - competing with that market doesn't make a ton of sense.

Plus, whether fair or not, having a minimum pricing point makes a service seem more premium -- more "ready for serious business." Now, obviously we've all been with expensive hosts that have terrible performance -- but you'd be surprised how many non-technical decision makers will choose a higher-priced offering over a lower-priced offering, on the supposition that "more expensive = better."
Oh I know it's not of your doing, HN would have changed it even if you had put a different title.
To be fair, VirtualBox runs flawlessly on OSX and Windows. I've also used VirtualBox without problems on Ubuntu. What Linux distribution you use ?
So did they dump the Bushevik war-pushing bitch or not?
This is the correct answer. qemu --accelerator=kvm is the principal way KVM is used.
I've not been following 14.04 desktop and the evolution of the Unity desktop closely.

Others may wish to comment with specifics here.

The main reason I (as an end user with one laptop) have moved over to Gnome based UI is LibreOffice and the ALT keyboard mnemonics.
Rebranding stuff isn't Not Invented Here syndrome. Relax. They didn't re-invent anything. It's just Firefox with a few patches for integrating with their desktop environment.
Plus, they gave up on their startup system. They'll be switching to systemd in future releases.
Since 10.10, when unity as desktop, ubuntu desktop is dead ... f..k Mark ...
I know where you're coming from, and I've had the same reaction to a few other similar posts on HN, however before I posted that reaction I realized two things:

1. If it's on the front page of HN then a lot of other folks around here probably know what it is already.

2. If it got voted up fairly quickly, it's probably also a big or important technology that I should familiarize myself with, at least superficially.

This is really disappointing. I have been a paying Loom member since shortly after the service was released, it's too bad it wasn't enough to keep it an independent company. After DivvyShot, Everpix, Snapjoy, and now Loom, I don't think I can trust another photo management startup again.

You mean paying $900,000 for a house in a suburbs isn't a great investment?
> The skill isn't the hard part.

Right, which is why I said that fewer (though many) people have the other resources.

> The problem is that molecular biology often doesn't work. So it takes lots of time and experiments to get it right. Which costs money. Lots of money.

And there's lots of people doing it now.

The real question isn't "does anyone have the resources to use these", its "can anyone come up with a business model where it makes sense to use these for further development".

What is your access pattern on that 215GB? Is there any of it that you don't touch for at least a month? There has been a lot of work in the past on hierarchical storage managers for Enterprise types but perhaps there is a market for one for regular users. Something that moves your data constantly into S3 or Glacier and then if you haven't used it on DropBox for a month it deletes it there, only to bring it back if you look for it.
