You indicate 2x availability in your HTTP header

This part never happens. The client simply signals that it would like 2x images if possible with every request, and the server sends the 2x images when it is possible, and 1x images when not. This is the exact same thing as has been done with gzip compression for years.

The client can choose to get 1x assets by just not sending the header indicating that it wants 2x assets.

"At the moment Steam is currently not accepting new game submissions as we transition to our new Steam Greenlight process."

Previously, I believe you had to contact them and talk to a human being to start the submission process.
yeah, that's also how I read it; but I just see that as 'paying MORE' than you would on a regular loan.

Of course... depending on how they do the percentage, it could be, you know, a good problem to have; I mean, if you end up paying a percentage of a very large income, presumably those dollars have a lower marginal value to you than when you were just getting started. And wealthy contacts, especially wealthy contacts that have an interest in seeing you do well are an incredibly valuable thing to have.

And it really couldn't be too crushing on the low end, as it's not like student loans, these would be subject to bankruptcy.

I mean, it seems like a reasonable idea; at least, more reasonable than most student loans.
Steam will work on Windows 7 and XP unlike the Windows 8 app store. It also runs on OSX and soon Linux. What exactly is Microsoft supposed to do about it?

Haha, you have a valid point, but how many authors using the svbtle platform are using IE at all? Svbtle is totally an author/editor feelgood platform.

Just a hunch and I am sure many will decry it as impossible, but I bet that microsoft buys valve in the next 2 years. It will be billed as a "hands off" type of acquisition (similar to skype) where they will simply more deeply integrate steam into other platforms like xbox and surface and keep them independent.

It just makes too much sense for microsoft to buy steam, regardless of the price. I know the steam fans would completely hate it, but it really feels like it is going to happen. Microsoft is dieing to have its own successful app store with a niche to have a advantage on the ios store and gaming/steam is exactly the type of 'we have this, they dont' which could completely make MS phones relevant again.

> HFT guys pay very expensive colo rates to be in a datacenter that is milliseconds closer to wherever the time is stamped on a trade

Yes, but that doesn't constrain the location of the exchange. The exchange (and all of the HFT colos) could be in Texas and the trading floor in NYC. (There's no reason to do HFT from the trading floor.)
the typical loan given to a person of that age in America is... different from the sort of loan you or I might take out. It is guaranteed both by the government and the debtor. You can't get out of American student loans through bankruptcy.

Personally, I think this is incredibly destructive; Banks will loan money as 'student loans' to people they'd never think of giving similarly sized regular loans. People that obviously have little chance of paying the loan back.
Can't Burner collect money from users for temporary numbers and then delete all records of number assignments when the numbers are "burned" by users? Twilio's recordkeeping might be more persistent though. Are there laws which effectively require Burner to maintain records? If not, Burner would keep a persistent record that User123 paid $2 for a number but could conveniently delete other identifying information.
There is an IMMENSE amount of stuff to observe and learn about this boring part of Mars. Geology, water formations, rock formations, sand composition, atmosphere, etc.

It's not just about Microsoft wanting to buy. Gabe has to want to sell also and not all founders are simply looking for an exit.
That has nothing to do with the context of the conversation.

The point is that it was designed to be cryptographically sound -- and therefore more heavily optimised towards entropy over performance -- whereas the need here is for the hypothetical entropy/performance slider.
Take a look at the TLD and you'll find your answer. Whether it's positive or negative, I don't know -- but here it's their ball and thus their ballgame.
huh. I disagree;

Quite often I will search for an error message, or system problem, and google will come back with mailing list posts... that I posted. It's irritating on the level of the "please see your systems administrator" windows error messages. If I knew the answer, I wouldn't be searching.
Full Show 8/7/12: Corporate Capitalism Will Kill Us All
Twitter is fine now, but, over the next few years, will become increasingly polluted, and brought down by the mandates of Twitter Inc. having to be a multi-billion dollar company, and make money off eyeballs. Twitter is _fine_ right now - I can chose my client, I can follow a clean feed - (all of the above are in my feed). There are NO problems whatsoever with twitter, for me, right now. In the next few years, that will likely change. Clients will become restricted, the feed will become polluted, and my eyeballs will be resold.

I like to get ahead of the curve.

I use Path, not Facebook. I don't watch commercial TV w/commercials. And I support app.net. Their business model is pretty straightforward - "The user is the customer, not the advertiser."

I like being the customer. That's why I'm paying $50. It's also why I'll migrate off Path to the first company that comes up with a business model that also foregoes selling my information and attention (While, like twitter, it's pretty close to perfect for me right now, I'm sure Path will go downhill - unless they find some ueber clever low-overhead approach akin to what Craigslist has been able to do.)
You don't know much about Steam or Gabe Newell then. They would NEVER sell the company. Gabe's mentioned before he's gotten big offers and rejected every single one. Valve has the highest employee retention rate and satisfaction rate in the industry. There's no managers, no titles, everyone's happy. Only a fool would sell a company like that. And Gabe's not a fool.

Don't let the silicon valley mindset warp your perception of what a company is. There isn't always an IPO or exit at the end of every company's rainbow. Sometimes, just sometimes, profitable private companies stay profitable private companies.
blows my mind
Here's a link to the YC FAQ where they talk about competition: http://ycombinator.com/faq.html. That said, I don't think we're a competitor to Justin.tv's live streaming app. We're angling toward fastest video possible, rather than live video that gets recorded.
I don't understand the confusion folks have about the business model (earnest confusion, not "yur dumb" trolling confusion).
App.net creates an API and people pay money to have access. Different tiers demand different prices. $500,000 in membership fees makes it sustainable (says Dalton).
The big question and, quite frankly, the whole point of Dalton's experiment (as I read him anyway, I don't know the fellow personally), is to test if there is actually a market for it, hence the kickstarter like campaign.
There are paid version of all sorts of web services that are offered for free that are sustainable. I pay for a server space and a domain names yearly. I don't know why something like this couldn't also exist for those who wanted more control.
Will Dalton's work? Time will tell, but something like this will happen and will happen soon.

EDIT: Incidentally, you do know that other people are trying similar things, right? Heello, for instance, is rebooting with a slightly different model:
http://thenextweb.com/insider/2012/08/08/twitpic-founders-he....
I agree this makes a lot of sense from a Microsoft perspective, not so sure it makes sense from a Valve perspective. AFAIK it's still a privately held company, Gabe & company seem forward thinking eneough that I could see them telling Microsoft to take a hike no matter the offering price.

To handle the redirection of nasa.gov to www.nasa.gov, they would need one or more nasa.gov A records that each point to a single IP address. These addresses would have HTTP servers that listen on ports 80 and 443 and redirect to www.nasa.gov. And this must be done in a highly-available way.

This infrastructure would be distinct from their existing web infrastructure (which appears to be Akamai-fronted).

So while yes, it's not the most difficult thing in the world to set up, it's not as simple as a DNS configuration change. Given NASA's strained budget and most browsers' handling of failed DNS lookups (automatically link/redirect to www.<domain>), is it really worthwhile? NASA thinks not.
Cool speed hacks.

An an improvement though, you only need two independent hash functions to run your bloom filter[1]. Strangely enough, this isn't well known and as such isn't implemented anywhere near as often as it should be (ie. it's not implemented here).

A comments section is for posting commentary. There's already a voting system for people to determine what constitutes a useful reply.

I have never seen light-on-dark done in a way that didn't hurt my eyes to read, but when it comes closest to being acceptable is when the light is not completely white and the dark is not completely black.

I generally find that text is most easily readable when the background is very slightly darker than white, and the text is slightly lighter than black, and this has the added benefit of leaving you open to emphasize elements by increasing their contrast beyond that point.

The main useful idea that I think this article gives is this: don't use up all of your dynamic range in one place.

I think it's excellent marketing - they're clearly targeting people who use the word "spreadsheet" to mean "lists that don't involve math" and it's always easier to keep speaking your target customer's language than to try to teach them a new one.
I absolutely love this stuff. The photos to me are strangely eerie, and even perhaps a little sinister.

I have trouble comprehending the size of other planets, photos like these make me feel uneasy (in an exciting way) because they are strikingly similar to landscapes we might find here on earth - yet it's a completely different planet! I'm no longer looking at mars as a red circle as shown in textbooks, but now as vast unseen landscapes that have never been explored before - a new perspective and a new age of discovery and I can't wait to see what else happens in my life.

It's also a stunning achievement. As I lie in bed looking up into the darkness, a boundless expanse of tens of millions of miles of absolutely nothing lies between me, and a small man made robot with the martian wind gusting and whistling gently over it. A robot that is cautiously making small movements, buzzing and whirring going about it's business with no one there to hear the sounds or see the movements it's making. A machine who's intentions are totally pure - it's sole purpose is simply to learn. A small beacon in a far-reaching expanse of barrenness and nothingness.

One thing I found recently I'd never heard of before is 'Venera 13': http://en.wikipedia.org/wiki/Venera_13

A Russian rover that landed on Venus in 1981 - designed to last the harsh environment of Venus for 32 minutes but actually lasted 127 minutes. An extraordinary engineering achievement to have a rover go from freezing space temperatures to temperatures of over 450c.

And it managed to transmit images of the surface:
http://mo-www.harvard.edu/microobs/guestobserverportal/Galil...

Absolutely stunning, and in some ways even more eerie and provocative to me than the Mars pictures as the environment it briefly operated in is far more hostile and as time was so limited the images are even more precious.

It does look great and is beautiful indeed and has very specific use cases. I might even be interested in using it.

But that wasn't the point, IMvHO the point was that if it doesn't walk/talk/act/etc. like a spreadsheet, don't call it a spreadsheet and confuse your users when the basic feature that has been in spreadsheet's since VisiCalc is missing. Call it what it's called, the Grid and leave it there.

And what about the performance penalty for the server to determine 2x availability for sites where only a fraction of images are available at 2x res?

I'm also not sure I fully understand how we clue the server in on where to look for the 2x version of a 1x asset. In the examples given, do the 2x versions have the same filenames as the 1x versions, but they're in the 'image' directory rather than 'img'? Seems like a significant limitation to force different assets to share the same filename, if that's what's going on here.
Well surprise surprise.

Naa. I think it was a pretty obvious move. Although my prediction was that they would tackle film and music before software. They obviously tried but after seeing what a pain in the ass it is to work with hollywood / music industry gave up for now. They renamed "My Games" into "Library" with Games, Media, & Tools subtabs and after giving up on the whole media bit just have "Library" now.

Software is a more logical step considering they're already set up to deliver software (games).
Without caption someone may think that pictures were taken on some Earth desert. It is surprising that mountains look quite "normal".
Actually, financial markets have employed non-Gaussian Levy processes in modelling derivatives for a long time (it is a bit different from the Levy distribution, I agree - but nothing stops the processes from having non-finite moments).

For example, a very widely used process for modelling information-driven timeseries (like stock returns) is the jump-diffusion model where the diffusion component is a Brownian motion while the jump component is a Poisson process.

The underlying volatility is often modelled using a different process - e.g. the SABR model, the Heston model etc.

There are similar cases for interest-rate processes (Hull-White/BDT etc) which have to satisfy conditions of mean-reversion and no-arbitrage across the yield curve.

See, it's not as if we don't realize that the underlying processes are mathematically inadequate to fully explain all market movements. But for a model to be useful, it has to satisfy two conditions:

1. Be able to produce a non-arbitrageable "mid"-price for making a market (ie if someone asks a trader to quote the bid-ask for an option, e.g.)

2. Be able to reproduce the current market prices of an asset/its derivatives. This requires model calibration.

Models are chosen based on how easily and how fast they can satisfy 1 &2.

Do they produce risk numbers that are believable? Probably yes, if the model has been calibrated and has been tested against out-of-sample inputs.

Do they guard adequately against event-risk (the thing you would try to signify using your "infinite" variance distributions)? Probably not - but then again, nothing does. How would you go ahead and calibrate the Levy distribution so that the sampling process can explain currently tradeable market prices? Would be it a "do once, leave forever" calibration? Or would it change from day-to-day (ie "local" calibration)?
I can't recall the study, but recently it was determined #444 is a perfect color for body text.
It's sad that with all of the world's information accessible to everyone, the author has to write an article instead of just using Google to answer his basic questions.
I went to a lecture by Geoffrey Landis of Nasa at the Eastercon Science Fiction convention in the UK. He worked on the last rover, and explained how to infallibly tell if the colour is false. There is no blue on Mars. Most false colour pictures end up making part of the landscape blue, which is both a give-away, and incorrect. Probably what you'd actually see would be less colourful and more dusty, given the pictures he showed us.
