I don't think better heat extraction would really change that much for today's CPUs (certainly when we head towards 3D chips it will become critical).

Gate delays are smaller at low temperatures; those LN2 overclocking runs aren't just fast because of efficient heat dissipation from the CPU, they're fast because the chip is being actively cooled to below room temperature.

So while heat dissipation is a factor, we're also close to the electrical limits as well. Otherwise water cooling (replacing the stock heat spreader) would get closer to LN2 runs. ALUs run at higher frequencies than the rest of the chip, but they're designed to do so (you'd have to shorten the gate pathways like a P4 to do that to the entire chip).

But ultimately, performance per watt is almost universally optimised for these days. It's critical in servers, laptops, mobile phones - The demand for 6ghz, 300W CPUs would be limited to workstation chips, even though we could probably engineer them to be reliable.

Power consumption is always going to increase super linearly with respect to frequency, probably as a fundamental property of any method of computation we use.

In my experience hiring great developers brings more challenges then benefits.

They are difficult to retain, They are difficult to be made satisfied, you need to change your company compensation rules to accommodate them and various other problems.

It's much better in my experience to hire a mediocre developer and train him in your domain.
Not sure why hubspot is having issues, I'll have to talk to the marketing guys who maintain the hubspot pages... Currently we don't let people claim their profiles, but will in the future. "login" is really just for customers at this point.
> I'd like to know the real reason why.

My guess is their plan is to try to leverage their desktop dominance into mobile. By forcing existing desktop users into their mobile experience. And hope that'll be familiar enough to buy old windows users into their mobile ecosystem, but not different enough to scare them away to a different desktop. The start menu is just one of the many pieces that doesn't work well on mobile. So they'll also get rid of it on the desktop, hoping that'll get desktop users familiar with WP.

Yea, a bad plan, but I guess that's their vision.

That's not quite fair. Some of them clearly were mainly critical because of the cost. Considering how quickly Apple cut the price, they may have been right.
When I wrote in PHP (and it lasted 10 years just to let you know), I would say exactly the same. PHP tasted better than, say, C++ Builder.

As we use to say in my country, "never tried things sweeter than carrot". I mean that was about me: I didn't know better things existed.

All that is done better in Python:

5. You don't need many of functions you use in PHP, for instance, _real_escape_string is not needed when you can do cursor.run("SQL Query param1=? AND param2=?", [param1, param2])

6. You can get help on functions in coding shell:

>>> help(open) # help on file opening function
or even
>>> open? # in IPython

With that I look into online or PDF docs quite rarely.

7. That's even faster in Python: you try things out in the shell, then save the shell session (IPython) and copy the code you need into the working file.

Moreover, while in PHP I was adding var_dump's everywhere, reloading a page 10 times before reaching the source of a bug, in Python I just do $ python -m ipdb same_script.py and have the debugging shell in the place I need, and it takes a minute of two to find the source of a bug.
There is some subset of the world's population who are a net negative in wealth creation, especially those living in expensive markets. (The very ill, mentally ill or drug addicted homeless people, most of the elderly.) Children also count if you're looking on a short time horizon, but you could do discounted future incomes to account for that.

There are values other than pure economic utility, but from a pure economic utility function, a poor person consuming medical services doesn't help the economy. The money paid (via taxes to doctors, equipment vendors, etc.) would be more efficiently used for another purpose -- it's the broken window fallacy.

It would be interesting to figure out where the net consumers stop and net producers begin, and maybe graph that over time and culture.

There are a lot of good reasons to favor an economy which is slightly less productive than optimum, but where a larger percentage of people are net-contributors; redistributing income or wealth from the positive outliers to invest in making more people net-contributors, vs. trying to maximize the total contribution, is probably a good social choice. But it's not the purely efficient choice.

This statement is essentially a post hoc ergo propter hoc fallacy.

No, it's not.

A post hoc ergo propter hoc fallacy is to assert that X causes Y _solely_ because X and Y co-occur. Philip asserts that doing the Ph.D. caused him to be wiser, savvier, etc, but he did so on grounds other than just citing their co-occurrence. Much of the rest of the article explained _how_ X caused Y, i.e., how doing the degree resulted in this or that bit of wisdom.

On a broader note, it really bogs down a discussion to point out 'logical fallacies' when they aren't there. Ideally, we'd all go out of our way to try to see another person's point, even when it's poorly made, but the antithesis of that is to criticize a point on technical grounds, when those technical grounds aren't even there.
Software development has lot of challenges and doing things fast isn't one of them.

We should get over the "x times more productive" notion altogether. Emphasis should be on doing things right than "fast".
Of course you can separate out the union effect within airline pilots. Long haul passenger jet pilots get paid a premium due to it; commuter pilots make absurdly little money, largely to try to break into the 747 market later, depressing their wages.

Did you guys first attempt to boot up in another us-east availability zone? They were not all affected as this post seems to imply. I had a slave DB go down but the rest of our deployment was unaffected (the rest of the deployment is in a different AZ as the slave DB instance but all are in us-east).
The radix tree caching mechanism is interesting, and seems very general. I'm new to techniques of randomized algorithm analysis, so I can't whip up a perspective of my own yet.

Does anyone else recognize this? Has it been rigorously treated? Seems like a similar approach to more applications in general using bagwell tries would be useful for both scala and clojure.
Seagate and Western Digital are way too busy making money hand over fist selling hard drives :)

A lot of the SSD companies aren't really making that much money. The fabs to make the memory chips are huge capital investments and suppliers have historically been bad at managing supply and demand leading to volatile pricing.

Hence the current drop in prices cited in the original article.
Well, er, good, fortunately my point was always in favour of spanning regions, not zones, so I refer you back to my opening note about not conflating disaster recovery (i.e. "we lost the DC, now what?") with high availability ("something within the DC is down, shouldn't affect the application").

Because in that analysis, the AZs never have represented an isolated unit of availability. They are clearly locally interdependent and/or sharing infrastructure. Heck, not sharing a continental plate is pretty much my #1 criteria for a DR replica.

NB: choosing to deploy in us-east just says to me "I want to save bucks, I don't care that it's got by far the worst availability track record".

I think this is one of Mike's best posts, actually. I've definitely benefited from addressing and improving weaknesses, and that has helped. But when I've focused more on neutralizing my weaknesses (by say, surrounding myself with people who complement my shortcomings) and then really doubling down on my strengths... that's when I've seen the best results.

I feel so sad that there is no competing product out there and thus FB has the balls to repeatedly treat its users insignificantly.

I graduated in 2003 with a computer science degree. I was one of two females out of 60 in my program. Neither myself or my other female counterpart continued on programming for very long after graduating. Why? Its simple after 4 yrs of basically communicating only with a computer we needed the human interaction element that is missing from programming. Women love to talk to real people, end of story.

Interesting story, bro.
In complement - I have a strong tendency to approach learning by "nibbling" at problems and soaking up the low-hanging fruit, not diving into them and front-loading all the effort. This isn't time-efficient, since with a lot of skills, intense practice is eventually required to get any result. But it lets me explore my interest in the subject, so that by the time I commit to serious study, I've developed a feel for what I want to learn, and how good I intend to become at it.

Addressing weaknesses does give you a certain kind of long-term flexibility, and in my case, I tend to incrementally become more motivated as I detect weaknesses in what I'm doing - so, for example, I haven't felt too motivated to learn advanced mathematics or foreign languages until recently. But this isn't the way to get a fast result. I'm in agreement that a prodigy's talent is derived from the willingness to be unbalanced.
I wonder what it would cost?

Amazon S3 pricing starts at $0.125 per GB per month. So if you just want to store an extra 500 GB that's gonna run $62.50 per month on a HDD!

Given SSDs are 5-10X more expensive who would be willing to pay $300-$600 per month?

Serious question: Any S3 users out there who would pay 5X as much for better performance? If so, what are you working on?
I don't advertise my company with facebook, for this very reason. I'm sure there are other people out there who feel this way. I spend about $1500 a month with Google, because they're trying not to be evil (even if they fail at the attempt sometimes). Not big money, by any means, but if a few thousand companies are opting to not advertise with facebook because they're kinda evil, it could start to be real money.
Startup advice is not meant be the ultimate guide to decision making , but to widen our knowledge and thought process.
Can you elaborate on why you think in this specific case user privacy or security conflict with Facebook's goals?
In this case, i believe we created a problem we did not have. Leap seconds is a dubious construct from the start, problematic with computers or space travel. We have added only 25 since 1972. Their unpredictability means they will be forever a problem with computing. We should either quit the whole idea or in the worst case allow them only every 25 years or so.

Edit: In fact there is strong indication that they may be abolished: http://en.wikipedia.org/wiki/Leap_second#Proposal_to_abolish...
Looking forward to trying out the updated notebook interface.

Any experience with it?

I tried to install and discuss the previous version with friends but failed. I couldn't find examples on the web, and installation with matplotlib wasn't working out of the box for Mac or Windows (not complaining, just observing it was not simple enough).

The notion that business owners pay less tax than workaday individuals is a media-created myth.

Uh, except that corporations pay taxes on net while individuals pay taxes on gross. It is entirely possible to structure your corporate income such that you would pay less tax than a normal individual.

You simply use your company to pay for all your expenses, take no salary and instead pull in dividends and/or stock that can be sold at long-term capital gains rates in a year.

I'm not sure how you missed all those stories about the selfless CEOs taking $1 salaries (and millions of dollars in stock) in order to do just that.

As I understand it the separate AZs can be the same data center but in theory they are completely separated from each other in terms of network/power etc so an outage in one shouldn't effect the others.

I doubt warranty is a major consideration when choosing between HDD and SSD drives.

SSDs on the other hand have great warranties. Crucial offers 3 years while Plextor and Samsung offer 5 years.
its the futex() call that is bugged, so therefore things that are highly multi-threaded... for example mysql and java!

Many unix things are not as multithreaded as those examples.
It seems obvious, to me, but I guess I'll spell it out:

Facebook wants access to your email so badly that they're willing to steal it. This is, in my opinion, among the worst things they've ever done for user privacy (and security, but mostly privacy in this case), in a long list of subtle, and not-so-subtle tactics.

It also has very real security consequences. The automatic contact list updates for potentially millions of users means that sensitive information is likely flowing into facebook servers as we speak, without users knowing it. Passwords, medical information, company secrets, who knows what else? Someone who trusts facebook enough to use it for social interactions might not trust them enough to know about their medical conditions, proprietary company data, passwords for other sites, etc. Facebook took away that privilege for many people with this change.

All that said, here's what's important: This does nothing good for users, and a few bad things. The fact that facebook made this change, knowing that the vast majority of users were not interested in using facebook email thus far, tells us that facebook thinks first of facebook. Even if there were no privacy or security concerns, what the user wants wasn't even in the equation, when facebook did the math on this.
Free for devs.
When you compare the Akamai stats to Statcounter's "North America" stats, the resemblance is a lot closer. It's possible that Akamai's traffic has a heavy North American weighting.
I think Facebook's position on this would be that the user goes into their contact book, selects the @facebook.com email address of the person they want to email, and then Facebook gets the email because it's on their service.
The article mentions using custom origins with CloudFront, and I don't understand why setting up origin.mydomain.com was required. At work, we use mydomain.com directly as the custom origin, and setup was super simple (just tell CloudFront the domain). Is there anything wrong with doing it this way?

I disagree with your claim that bandwidth in 1st tier cities is anywhere as good as in the states. At work, at home, and in the cafe my internet is always slow, even when pinging local sites (Beijing). I'm always amazed when I go back to the states to visit and I can use...Netflix at my sister's place. Americans have bandwidth that we Beijingers can only dream of.

True about IE and banks, but its easy enough to use IE when banking online and switch to whatever else you want.

I don't know what the numbers really are; I suspect IE use is still high but might be lower in Beijing given all the Macbooks being used by the middle class.
Even if you don't have java installed but you're running on shared infrastructure that might be running MySQL/Java elsewhere it's a crazy day. My inbox is full of performance-below-acceptable-levels/high-load alerts.

As I understand it, when an email address on Facebook gets synced to a phone, that's just a cache. Any updates to the email address on Facebook automatically update the cache. When friends update their email addresses, the cache gets overwritten and you don't have their old addresses anymore.

But now, Facebook changed people's email addresses without their permission. The cache gets updated, and boom, the old address is gone.

But what makes it more scary is that people don't actually remember that they originally got the address from Facebook and they don't understand the caching behavior. All they know is that the old address is gone. So they think that email addresses that they didn't get from Facebook are also at risk.

The workaround is to manually copy email addresses from Facebook to some other system. Any email addresses you get from Facebook by automatically syncing aren't safe.

It's a pity; after all, most of the point of the system is that you shouldn't have to manually update your address book when your friends change their contact info.
