The logic of evolutionary biology can get tortured, particularly when someone missing something obvious is torturing it.

The obvious point that you're missing is that evolutionary status and social status are pretty much unrelated things. Evolutionary status is how many descendants you have in the far future. Social status is what society thinks of you.

In our evolutionary past the cost of being "ruined" was access to fewer resources, which lead to a decreased survival rate for you and your kids, and decreased prospects for future children. Today the result of out of wedlock pregnancies is more descendants since we all have sufficient resources for basic survival. The result is an evolutionary pressure towards avoiding the effective use of contraception, and for enjoying sex.

This happy state is, of course, unlikely to remain for an evolutionarily significant time. The simple reason for that is that the continuation of this state will result in exponential growth in human population, leading to resource exhaustion and a Malthusian nightmare. (Current projections appear to show a halt to exponential growth due to economic and societal pressures. But that won't last more than a few generations as birth control creates a very strong evolutionary pressure for avoiding the effective use of birth control. Even modest success at that will reignite exponential growth.)
Peter did admit his mistake about superfetch (he thought the xpnet thing was counting that too as used memory), but he's still right about the overall metric being wrong -- see the comments to http://exo-blog.blogspot.com/2010/02/editorial-what-took-you... .

edit: and do you think he doesn't know about procexp/perfmon? :)
My vote goes to entertainment value, because the stories don't completely add up. When he was implementing the case-insensitive logins he would, of course, first have to run a query to see if there are any users whose login names collide without case sensitivity. That query would run (according to the slides) really slowly, because it would have to essentially do something like:

SELECT a.id, b.id, a.username FROM users AS a, users AS B
WHERE a.id != b.id AND a.username = b.username AND
BINARY(a.username) != BINARY(b.username)

At that point he'd realize the query is taking forever, and use mysql-top or something equivalent to kill the query.

Edit: I realize that most likely the username column had a UNIQUE index already, making this query unnecessary.

--

In his example of find_in_batches where he has to make some changes that applies to all users he makes it sound like the User.all is the big problem because it does a `SELECT * FROM users`. But even when you break up the work in parts you have to be careful, because by the time you're done processing a few of the existing users may have changed already. So as your database becomes too large to do your updates in one big atomic transaction block you almost always have to follow a process like this:

1. find set of rows that match the problem (in batches)

2. apply the (expensive) fix/migration on those rows

3. go back to 1 until the result set is empty

4. do (1) and (2) in a big transaction (but since there are only a few rows, that's fine)

Of course there are a hundred ways to upgrade a live database safely, but there always must be some kind of process in place otherwise your database is going to go down all the time.

Which history are you reading? Democracy is not a "fairly young experiment". The ancient Athenians had an impressive democratic government from 508BC until it was destroyed, from the outside, in 322BC.

You cite "multi-hundred years of stable government by kings" like there are no power struggles when a given king dies, and like "stable" is even remotely near what we'd call stable or desirable (freedom?). Which history are you reading in which these wonderful benevolent king-systems (not just singular kings if you want "multi-hundred years") exist? Cite one.

There is no counter-corruption in a system with a powerful executive and no democracy for long. Without checks on corruption and a powerful state there is no freedom for very long. I can't believe the suggestion that the west moves to the model of voting in leaders with "near-unlimited power to do practically anything they want" is being taken seriously in a time when questionable wars have been started and torture policies implemented by the already too strong executives.
What? Plugins can’t modify the behavior of built-in tools, and are therefore absolutely powerless to fix this problem, which affects all of the compositing of layers in Photoshop, and many of its other tools.

(As for scaling in particular: many plugins already exist using better methods than bicubic interpolation, and avoiding problems like the lack of gamma correction, etc.)
Sorry for the lack of knowledge, but they were not obvious to me. Is it possible to use them on GAE? I thought, reading thei pages, that only Python and Java could be used.
You should learn more about the distinction between the GPL and the LGPL. Whether you make a library that is GPL and include it in a non GPL program, or you have a GPL program and want to include a non GPL library, both cases require all code to be released as GPL.

The GPL does not care about "library" verus anything else. The GPL is somewhat oriented around the constructs of C, but there have been clarifying guidelines from the FSF and in general its not hard to see how everything fits in for another language.

The LGPL, on the other hand, makes specific exceptions for libraries which are linked into an existing application. So long as a proprietary application is using the library in such a way that it could be removed and replaced for another compatible version, it is not considered a derivative work under the LGPL and is not subject to release.
Zookeeper/Chubby vs Mysql NDB
I have been reading the Paxos paper, the FLP theorem etc. recently and evaluating Apache Zookeeper for a project. I have also been going thru Chubby (Google's distributed locking service) and the various literature on it that is available online. My fundamental usecase for Zookeeper is to implement replication and general coordination for a distributed system.

I was just wondering though, what is the specific advantage that Zookeeper or a Chubby like distributed locking system brings to the table. Basically I am just wondering why I can't just use a MySQL NDB Cluster. I keep hearing that MySQL has a lot of replication issues. I was hoping some with more experience on the subject might shed some light on it.

Functional programming and all its pros and cons are a recurring theme here on HN, AFAIK.

I did not want to mean that everybody here uses it or advocates it, but I think almost everybody knows what leads a developer to move to functional programming.
Well crap. By that argument, a consultant's rates are dependent on rents and car insurance rates. There is no such correlation. Consultant rates are determined by their perceived value of themselves and their perceived value to whoever hires them, in some form of negotiation. Obviously this has to cover all the listed costs, since it's not worth it to said consultant otherwise, but that's not what determines the price. This article makes it sound like justification, in the "Oh look at poor old me and all my costs, I need to pay all these things and therefore I am so expensive" sense. Nobody hires a consultant because said consultant cannot make rent otherwise (nepotism and such excluded). They are hired because of some perceived value to whoever hires them.

Because human visual response is non-linear, doing operations like gaussian blur (which is an artificial operation, unrelated to physical phenomena) in linear light space isn’t “more correct” in any absolute sense. Calling a gaussian blur “camera blur” or “defocus” (whatever the color space) is just inaccurate and confusing.

Compositing and interpolating should definitely be done in linear space though.
I can't remember a website that was posted here within the last few weeks
There was a website that was supposed to be a portal for the internet (launch page). It's whole schtick was that it was simple and it had 4 icons for web services you could click on links to. I really liked the design and was wondering if anyone remembered what it was called. I think the url started with a 4.

I don't think there is a case in which 'direction' figured in a copyright decision. The criteria are much more straightforward than that.

You never answered my question about what specific GPL language excludes the Linux kernel from the kinds of claims you are making about Wordpress. Or Mozilla (you claimed Mozilla loading a GPL'ed extension makes it GPL which is an interpretation that makes the GPL not 'viral' but an actual virus)
Without more information on what problem you're trying to solve or what system you're trying to build, it is hard to provide very helpful advice.
I assume you also believe that mafia films are glorification of criminal behaviour, war films are teaching our youth to become heartless soldiers and old cowboy films are promoting ethnic genocide.

How about we have a single point of view in the world? We could make a big world conference and come up with a safe, polite, nice sort of music, a correct sort of behaviour, a proper way of dressing, and then we could all just conform to that. Perhaps you would like to draft the first version?

As I would frame it for free market economists:

There are firms and projects which have benefits which cannot be easily turned into a return for investors (either directly or indirectly) but whose benefit far exceeds the investment of dollars and effort, which are currently severely underfunded (with a lot of variation on the input stream) because the government through a combination of politics and incompetence cannot wisely discriminate between potential recipient, because passersby on the street cannot acquire the requisite facts to make an informed decision, and because corporate entities almost all currently buy into the idea that charity investment is a PR stunt, and nothing more.

It is to the benefit of society to invest in these firms and projects, so if an individual is truly other-centered they may push hard in finding and working for these causes, whose profits don't appear on the bottom line but are spread throughout society.

An example? The all around helpfulness of entrepreneurs, investors and advisors in silicon valley, or hackers here on hacker news. These people put an awful lot of effort into helping out their community, often to absurd lengths: the benefits do not solely or even significantly accrue to them (as is typically the case in profit making entities founded upon an exchange of currency for a good or service), but by their participation the community grows stronger along with their standing in it.
Yes, most LCDs are still pretty bad at keeping colors constant with viewing angle. To see the effects being talked about precisely, get a calibrated CRT. :)
> Calling a gaussian blur “camera blur” or “defocus” (whatever the color space) is just inaccurate and confusing.

Nonsense. When you defocus a camera, you get an effect that's comparable with a gaussian blur performed in linear space. Blurring is a well-understood operation that's existed for a long time in the analog world, before we ever did any digital processing.
Since you can do that selectively in software there's no reason Flash shouldn't do it while the tablet OS and other applications should.

Touchscreen UI is all good but there will always be a class of applications that want both more precision and mousemove events.

As a personal note, touchscreens are painful to use unless you only have functionality behind big baby-size buttons. I wish I could always switch to such a touchpad mode if I wanted to.
In my job if you don't make notes then it pretty much legally never happened.

It's done wonders for my productivity having to make constant critical notes. Especally if you have to go back to a problem after a break.
This site is brilliant. Check out the translation for these lyrics: http://rapgenius.com/lyrics/The-notorious-b-i-g/What-s-beef

It's quite funny, for example:

"It ain't hard to find me, number one with the "booyaka"
Give me the Remy and the chronic, ain't no telling what I do to ya"

The explanation of the lyrics:

"When Biggie gets drunk and high off Remy Martin cognac and bomb-ass weed, there’s no telling what he’ll do to you! (esp. if you’re a sandwich, watch out! Your days are numbered)"
The industry standard for measuring the efficiency of a power generator does not include transmission losses.

However, I have seen people include it in the past as a way of manipulating the numbers. I doubt this is the case with this number. It should be close to 60%
Those are moot points

Collateral requirements? most bank lending apart from mortgages is uncollaterilized, even mortgages are not fully collaterized, you can default and the bank wouldn't recoup their full loan amount by selling the house.

Banks routinely deal with huge amounts of risk - trading stocks and bonds. Startups would just be a new asset class to exploit for them.

This is just a random sample of rap songs from my recently played playlist.

Honestly, I'm super jaded by the types who listen to top 40 radio and think that's all there is to rap/hip-hop. It's an extremely diverse genre and the vast majority of what you hear on the radio or in clubs is just one part of it.
Much larger in what sense exactly? By our count we host twice as many repositories as they do.
Basically..
* I have a homogeneous distributed system.
* I need some means of maintaining consistent state across all my nodes.
* My system exposes a service, and interaction with clients will lead to some change in collective state of my system.
* High availability is a goal, thus a node going down must not affect the service.
* I expect to system to service atleast a couple of 1000 req/sec.
* I expect the collective state of the system to be bounded in size (basically not too many inserts/deletes... but lots of updates and reads)
> In many ways it's looking like we have created the worst of both worlds - a royal court of privileged elite governing only for themselves, with a neutered king serving only to take the blame.

So, you're claiming that giving all power to a single individual is a 'stable' form of government? If the executive branch wielded the full power of the government to enact laws at a whim and to be judge-jury-executioner to anyone it so desired, we would be in governmental nirvana? I think that you might want to check that your prescription glasses weren't filled by your local stained-glass craftsman, because you seem to have a pretty 'rosy' view of the history of 'all powerful' leaders.
That's a good point. Almost everyone will play the leverage game once it gets popular: this means that opportunities for the kind of statistical arbitrage people like mellow out, and what's more the whole stock market will be so highly inter-networked that the short term stock price will be fragile. But through judicious investment and directorship one's illiquid investments -- as Berkshire Hathaway tends to make them, can be multiplied far more profoundly than traditional leveraged investment. In this way B.H. operates more like private equity or a venture firm -- what's amazing is the difference in scale.

Incidentally, I worked out the same numbers for my own financial situation. It doesn't make a lick of sense for me to save up and diversify at this point, or even actively invest to chase the best return I can, not now. All of my money and effort should go back into my startup, so that I achieve profitability there, and liquidity.
As in any genre there is a wide range of talent and musical ability among rap artists. The record industry is really good at printing one hit wonders and then burning them up. Those are probably the guys who are making the songs you are referring to. This is not unique to rap, it happens in pop, alternative, rock and roll, heavy metal and any other genre. I could easily say "metal is just screaming" or "alternative is all the same crappy guitar chords" and I would be kind of half right some of the time.

If you take a look at some of the more accomplished artists with staying power you will discover thoughtful lyrics and complicated music. Jay Z has been getting more and more musical over time. The American Gangster soundtrack was an explosion of funky horns and beats that really set the tone of the album to that of the film. Death of Autotune doesn't have an electronic note on the track. This is not to mention the vast pool of talent in the underground hip hop and rap scene, which is something you should really investigate if you are going to give the genre an honest examination.

If you don't care for rap music that's fine, but saying "it all sounds the same" just makes it obvious you don't ever listen to rap music. What would you think of me if I said all classical music sounds the same?

Just out of interest - why? Do you not trust developers to keep an eye out for bad generated queries, or do you have a problem with ORM generated SQL in general?
More like not his QA department.

And to the author of that blog post, dude, how bloody entitled do you have to think you are to bitch that Apple didn't catch an obscure bug in your application. What do you think they do, play through every scenario of every game? If you had made a, say, unit converter, do you think that Apple would check if all your conversion formulas are correct? Do you think they should?

The review process is in place for one purpose - so Apple can protect iPhone users from things that are obviously detrimental to them and their experience with the device - things like obvious crashes, like obvious use of private APIs (which would lead to obvious crashes at some future point), and like obviously inappropriate content.
Did not know that, great tip.
Apple's approval process is screwed, because of delay. It's simple isn't it ?
TBH, by hetero life mate was working on the redesign until last week. He left of his own volition, and I can pretty much guarantee that all the innovative ideas in the world won't make it through the political processes that exist there.

It's too bad - musicians alone deserve something better.
You can make ImageMagick do quite sophisticated image interpolation, if you want.

Pretty sure GIMP’s main goal is to just do what Photoshop does.
Well, “comparable” insofar as you don’t care about the details, I suppose; you could also call a square or triangle blur kernel “defocus” if you wanted.

A real lens blur doesn’t look much like a gaussian blur for someone who is familiar with both and paying attention.

For explanation, see for instance http://en.wikipedia.org/wiki/Bokeh
I think his objection is that the process means bug fixes are really slow to appear, and he has no way of communicating with his customers.
Implementing Full-Text Search for Core Data (iPhone)
It would seem that there is a bit to much hype around the product. Perhaps as more information comes out, the more 'out there' claims will gain credulity.

The real power of this discovery is going to be the ideas and patent behind it.

Since the dawn of the industrial age we have depended on some form of combustion/heat generation to produce steam thus turning turbines and creating electricity. This technology might be the first real step in generating electricity cheaply and efficiently through more elegant processes.

This may be the first iteration of changing the way humans gather electricity.
It's for exactly this reason that I keep a personal, daily journal. At the end of each day, just before I go to bed, I take a few minutes to reflect over what I did that day that I'd like to be able to remember in 5 or 50 years.

I keep it mundane: I did this, then I did that, and after dinner, I did this. If commentary occurs to me, I'll jot it down, but if not, a Joe Friday "just the facts" transcription will do just fine. It usually takes only a few minutes. And yet reading entries even a year old can be fascinating: the amount you will forget in a year's time (to say nothing of a decade) is enormous. Even recording just big-picture outlines of day to day life makes a great journal.
Perverse use of browser history hack and social networks
Excellent. This should help, although unfortunately such a system is only as good as the average quality of the user-base.

That's why I advocate selecting a group of trusted users to do it instead. Its non trivial to select this group correctly, but I think the end result is more effective. Over time you can expand this group based on the users that have the highest percentage of civil comments. Once you get the ball rolling, the group simply scales as the site gets larger.
It's even better here in the uk. We get one day delivery :-)

sometimes I can order stuff at 5 pm one day and it arrives 9 am the next.
Well. Developer is at fault for not testing his software.
Apple is at fault for taking weeks to approve a bug fix.

Quality of the app store is irrelevant because it appears apple is just trying to be in control and stop viruses and the like.
Isn't this more contemporary R&B? Although it makes use of a hiphop rhythm, and there is some rap interjected here and there, it's not really what you would call a rap song, is it? Also, I was hoping for something considered really great in the genre, something your children will listen when it's no longer fashionable. This song, while not terribly offensive, seems rather vanilla and it's hard to imagine people listening to it in a couple of years, let alone decades from now. I doubt Autotune will age well.
