I understand how process-per-tab protects against cross-domain attacks. In protecting against cross-domain attacks, Chrome's architecture is safer than IE's since IE will often put multiple tabs in the same process. But, I don't think the number of tabs per process has an effect in the ability to prevent exploits of the local system.

The feature of Chrome and IE Protected Mode that protects against local expoits is basically the same. There is a "main" process that has access to the local system (files, registry, other processes). And, there are some "sandboxed" processes that do not have access to the local system except for a communication channel to the main process. Any time these browsers interpret some input from the internet, they do so only in the sandboxed processes. The only way a sandboxed process can access local resources is by asking the main process to give it the local resource through the communication channel. The main process asks the user to approve the request before accessing the local resource on behalf of the sandboxed process. As long as the main process implements its side of this communication channel correctly, there is no way for malicious web content to break out of the sandbox. That is the case whether there is one tab per process or more than one tab per process.

Not too good. In the 20 to 40 Hz range you are looking at a 15% reduction in sound intensity (NOT in decibels, a 10x logarithmic measurement of sound) per 1/4 inch piece.
Say you have 100 dB of sound coming in at 30 hz the math works like this:
log(10E6) = 10 or 100 in dB (because of the 10x)
10 000 000 * 0.85
=> 8 500 000
log(8.5E6)
=> 9.929 or 99.29 in dB (no perceptive change)

At the higher freq (4000+ Hz) you should see drops of 50 to 70% for a 1/4 inch piece. Using 100 dB again we have:
10 000 000 * 0.40
=> 4 000 000
log(4.0E6)
=> 9.602 or 96.02 in dB for a 1/4 inch piece (much better! A clearly obvious change)

Another thing to remember is that 1/4 + 1/4 != 1/2
Say we use the 30 Hz example it would be:
0.85 * 0.85
=> 0.7225 or a 27.75% reduction, NOT an additive reduction of 15%

For reference of how loud things are:

Motorcycle right beside you: 100 dB
Subway train about 200' away: 95 dB

See: http://www.gcaudio.com/resources/howtos/loudness.html

Hope this clears up some things :)

The company I work for spends over $50,000 daily on advertising, for a purely virtual (downloadable software) product. This is almost, but not quite, exclusively search advertising. Dollar-wise, over the past few months, the split is:

Google: 87.2%
Yahoo: 8.8%
MSN: 2.4%
Ask: 1.0%

With LookSmart, CJ, NeverBlue and Right Media taking up the sub-one-percent slack.

This is (like other people have noted) largely influenced by what our product is. Search marketing (as opposed to display) is by far best for us, and Google is by far best of search. There is a chance there are some campaigns I've missed.

This shouldn't be about "payback". The first post in this thread (kirse) makes a fair statement about China's fixed currency. But does take it too far. Similarly, China not accepting that it is a partner in its situation of the USD is also taking things too far. I think most of this is political response to China's leaders having to answer to its own "middle class" trying to explain what happened to their dream.

It is very true that China would not have its position in the world today if the U.S. had not made credit so cheap to not just U.S. citizens, but the entire world. This is key to understand: the problem with the USD is the world's problem not just Americans. Bankers, traders, homebuyers worldwide benefited from the loose credit policies of the U.S.

Mr. Zhou's statements on changing the system are worth looking into. But keep in mind that there were many smart economists that studied the current set of rules for decades prior to loosening U.S. banking regulations and most of them thought it would work...they were wrong. I'm sure if we jumped into Mr. Zhou's "new IMF system" that in 40 years, there would be externalities we could not have predicted.
That's what I think too. But look at how often car radiators and air conditioner coils have to be replaced. Hopefully since this doesn't have to hold pressure, or work at very high temperatures, it should last longer than the house.
Fibonacci Web Design: Making web pages using harmonic proportion and Fibonacci numbers
Someone on reddit claims it's an exact copy of this:

http://www.maxmind.com/app/geolitecity

I haven't verified that claim.
Does anyone know the reason behind this change? Is it a measure because of cost of operation in certain countries or is it a legal issue?
If my recollection is correct, when this was happening The Economist magazine was also in favor of it. And one of the reasons they gave was that a more diverse business will make bankruptcy less likely.

And logically I have to agree with that. It also seems to me, that is not what caused the crisis.

I think the core of the problem is

A) Too much risk was taken on because there was huge incentive to maximize profit, and very little disincentive to minimize risk. People were gambling with other people's money.

B) Companies that were allowed to get too big to fail.

So I think we can keep mark to market, and naked short selling and even the repeal of Glass-Steagall as long as we have legislation in place to prevent systemic risk.

Something like monopoly laws, but instead of monopoly, companies would be charged with being too big to fail.

If the courts convict them of being systemic risk, they have to find a way to split into at least two parts, but they can do it while preserving as much share holder value
as possible.

And then no more bailouts!

I am not sure how Glass-Steagall eliminates systemic risk and the too big to fail scenario? It makes it less likely but does it eliminate it?
How can the user be sure that a program won't cause data loss?

An easy way to do it: never delete anything. This isn't too different than my OS X setup at home with Time Machine. I have exceptions set up for things like my VirtualBox images and movies. A more advanced system that can keep deltas of binary data would be even better. A solution designed for the clueless end-user would have some sort of function that would automatically keep less frequent backups for larger files.

Run out of room? The salesperson talks you into a hard-drive upgrade. HP, Dell, and Apple would be happy about this!

More accurately, never completely delete anything. The system would always keep around at least one version of everything. Yes, this would mean that secure delete is impossible, but this sort of system is for the casual home user. If you need secure delete, use a different system. If you are doing esoteric things with lots of large files, use a different system.

How to go about getting a credit card processor
Originally I wanted to do all of the password wrangling in javascript so that it never hit our servers. We only need it to make the follow buttons and the little viral message work (we ask for confirmation before posting and say exactly what it'll post to minimize the evil), but using HTTP basic authentication with Javascript seems to be a no-go, so we just bounce the request off our server. All of the data that we pull is just public data that's grabbed with our white-listed account.

I'll look into OAuth in the future. At the time I just saw in the Twitter API docs, "For the time being, HTTP Basic Authentication is the only supported authentication scheme."
It's the former, sort of... See the comment on the post titled "Joost, HodgeStar, et al": (I can't find a permalink)

great article, made some very good points about the efficiencies of railroads vs. trucks.
I checked his ip->city database against a dozen class C's with which I am intimately familiar, and in every case they were either correct or as correct as possible (i.e. someone in that /24 is located in city X, even if most people in the block are located 25-100 miles away). I specifically looked at cases where the ARIN information would lead one astray, so it appears that is not the primary source of location data.

I think there is a lot to be said for both sides. The one thing we don't want is a situation where we keep giving money to management that is unable or unwilling to become profitable. Nationalization and bankruptcy are both proven options, but the sort of bailout currently in mode is not.
Peek Pronto: The world's simplest email communication device now supports SMS
A nice focused service
Nice Idea. How are you going to handle blacklisting (email?). I believe expanding on the interaction part like replies to say something like surveys would greatly increase the value.
I agree on your point B, I think that companies can get to a point where they are like a cancer, they themselves thrive (for a while) but they can end up destabilizing the host organism. Not a perfect analogy, and I worry about giving the government the power to declare that a company is "too big" because historically such powers are abused. IF such size could be pre-defined on purely objective measures, perhaps there is a way it could work.
I'd like to add that I find it amazing how devices that focus on simplifying existing technologies are taking off in the marketplace; Peek and the Flip series of camcorders being the big leaders.

The hardware behind all this innovation has been around for years, but the UI must have always been the stumbling block that's lead to the success of these two products.
Probably not. Water entering the house comes in below the frost line so the pipes don't freeze in winter and the ground temperature below the frost line is pretty constant year-round. There is a small change, but the water coming out of my cold faucets is almost the same temperature whether is 100F or -25F outside.

"Now that disk space is so cheap and many of the data models don't benefit as much from normalization, JOINs are easy to leave behind."

JOINs and data normalization were not created to get around disk space constraints.

For the average web application not running on app-engine like infrastructure, I believe the following order of questions would be more prudent:

1. Do I need a database?
2. Can I work with a relational database? SQLite? PostgreSQL/MySQL?
3. Now, do I really need the new hotness?

And if you do need the new hotness, may I also suggest Tokyo Cabinet? I am afraid I can't rate its 'value' on a scale of 10, but I'd say it's pretty high for a free product.

how does pricing scale with volume?
But other lawmakers criticized the provisions of the legislation aimed at discouraging community groups from pressing banks to make more loans to the disadvantaged. Representative Maxine Waters, Democrat of California, said during the House debate that the legislation was ''mean-spirited in the way it had tried to undermine the Community Reinvestment Act.'' And Representative Barney Frank, Democrat of Massachusetts, said it was ironic that while the legislation was deregulating financial services, it had begun a new system of onerous regulation on community advocates.

What really gets me, is that the very people that were pushing for banks to loan money to people who couldn't afford the loans (ie Barney Frank), are out there in the media as the biggest decriers of the financial mess we are in. They are so eager to lay the blame on others, including big, nasty Wall Street. Everyone is culpable here.

I would like to hear more on this. Amazon and PayPal have similar published fee structures for low volume accounts. Over half the things I buy online use one of the big 3 or 4 "gateways". My feeling is that by buying through them I am getting more protection. I certainly like the fact that my credit card info isn't sitting around on many small mom and pop biz mysql DBs.

Are there any metrics showing my intuition is not correct?
I like the idea. The visual design is really nice - I like the logo, color scheme, and fonts.

The video is a nice intro for devs. You might consider preceding it with a less technical 'overview' video that shows your service in action.
It's simple: there's an expectation that some amount of due process has been done before granting you a merchant account. It's harder to setup than a Paypal account. Therefore it's more difficult for crooks/irresponsible people to get a merchant account than a Paypal account, therefore you look more professional with a merchant account.

Barriers to entry can work for or against you.
Hi. This is interesting.

You theoretically could offer snail mail as well - there are services that translate from email to letters for you.

A left field comment -- Right now, this is a developer-orientated service. You could market it to consumers - e.g. This is my messagepub address, send your messages there. Then the consumer as a receiver gets to decide on how messages get routed to them.

A more difficult play, but it would be interesting to see. The revenue part might be more difficult, but perhaps there are ways around this.

It would also have the advantage that applications don't need to know and maintain everything about you (e.g email, phone, cell, twitter, etc, etc). Even in this model it looks like every app is responsible for maintaining all the required info.

The consumer could just maintain it in one place... Sort of like a Grand Central for the Web.

Someone can't make public domain software unpublic. They can take it and do what they please, but they can't change the terms of use for others.

AFAIK, generally US Government developed software is generally public domain (unless it's classified or something) and I doubt that means someone can just "assume ownership" of it.

It's a pretty esoteric feature, I'll grant you, but it's needed to implement several useful, more user-oriented features. The big one is deferred fields, which in certain situations can give apps enormous performance gains. If you're interested in how these features are related, Malcolm lays it all out here: http://www.pointy-stick.com/blog/2009/03/23/yak-shaving-adva...

It's important to understand that often the simplest features have the most complex underpinnings. In other words, simple APIs often require complicated internals.
That's what the article is saying if your storing it on "small mom and pop biz mysql DBs" they won't let you get a account.

This is an interesting example to think about.

One might consider that Apple's failure after Jobs' departure suggested Jobs was successful. We're getting into the crux of the interplay between success and failure. They are dependent on one another, and they change with time. Again, this totally undermines any sort of binary representation one might try and espouse.

They're different threat models.

Vista Protected Mode (IIRC, it only works on Vista, because of XP's session security flaw) is like privsep SSH. It's primary job is to keep malware from persisting.

On Windows, my understanding is that Chrome Sandboxes do the same thing. But what the process-per-tab model is most notable for is defending against cross-domain attacks. Which, if you ask me --- and I'm a Microsoft booster --- is the more important threat model. Browser-resident malware is where we're headed.
Thanks for pointing this out. You should only see the banner on IE6. We'll fix that.

Yes, that's definitely a big part of it - the fact that the same company can both provide a loan and then insure that same loan creates an ethical conflict of interest that calls into question their ability to objectively quantify risk, as well as creating an illusion of stability with these risky assets through false claims of insurance. The article gave an example of a company at the time (Citigroup) that would have had to split their insurance underwriting by law, which arguably would've created a more accountable and less entangled situation than having it all under one roof.

So what did the less ethical banks do with these troubled assets, since I'm sure somebody in the top ranks had to know what they were getting into? Bundle them up with a bunch of their other more reputable financial products and resell them to others. That's the part that's been getting a lot of the attention lately but it's only a symptom, not the root cause of the problem.
