> MongoDB(page based storage) Citation needed. Which database system on earth doesn't do page based storage? In fact, you cannot get any durability guarantees if you don't write page-at-a-time. MongoDB is relying on the operating system

... you'd think. However in practice most operating systems and/or file systems and/or disks cheat. fsync() is usually buffered in the hard disk itself. You can disable that and force the hard disk to truly write out on fsync, but that is s

You could probably pull that off if you implement it like full text search indices in e.g. Lucene. Have every modification create a "diff" skip list that takes precedence over older skip lists, and then have a merge operation that runs asyn

Re 2.: you can get significant improvements when compiling to native code. You still have to dereference those function pointers, which is essentially the same as a big switch statement (if not worse, your function pointers might be anywher

I've actually written a compiler from database queries to native code (JIT'ed bytecode actually, but doesn't make a difference here) once. Some queries in databases are indeed CPU bound, but the general statement that well-optimized databas

I posted this as it really seems to be a trend (as mentioned in the article). The US border controls get more and more ridiculous for foreigners - but only in a security theater way. None of these moves seem like they could actually defend

I'd assume that evolution happens quite fast if the trait is already there in the population (people are more or less light-skinned everywhere) and there is such a strong selection pressure (much more food available if you can adapt to the

Since when is SHA1 easily reversible? Did I not get the memo? Salting should have been fine.

Actually the title attribute is used to annoy users who have their mouse cursor on the page by displaying exactly the same text again that's already in the link or para. At least in 90% of the cases I've seen it used, probably by some overz

+1 on the font size - that's a big problem in particular if you happen to have a large screen. But forcing everything into the same font seems a bit excessive; I've actually seen a couple of sites make really nice use of fonts, and you can

It's usually less of a bandwidth issue and more of a configuration problem - e.g. default Apache tries to spin up some 50 processes to handle requests, which can drive a small server into swap space.

As someone who occasionally ends up on Windows having to do Terminal work, thank you. A proper terminal emulator on every platform (well, every platform I care about) is a huge win. I might even move to this entirely if it adds support for

I wonder what's the point in writing a book about Dart, where the language, environment, toolchain, compiler(s), and community are still very, very unstable. At best, it could be an intro saying "this is what they're trying to do"; but you

XML is self-describing, it just so happens that XML's data model is not identical (and actually not even close) to SOAP's data model, or the typical programming language's data model. XML itself only describes a text encoding, XML infoset d

That's cool, but how many users will understand what's being asked for? If the user says yes (and users will always just click the "go on do it" button), they basically agreed to being tracked indefinitely :-(

That could be easily spoofed by requiring just some username on the server side, assuming you set up your web presence such that these links always include some username. The HEAD request won't help you there.

Part of the problem can be that operating systems and databases work in block sizes of 4k (8k on some UNIXes), which is appropriate for regular disks, and flash SSDs are organized in blocks of 64k, 128k, or even larger blocks, which need to

I think what all of these countries have in common is that they have a strong entity negotiating prices on behalf of the patients, drastically lowering the price, and to a varying degrees also dictating what treatment is appropriate. It'd b

How does an intranet/VPN help with avoiding malware on end user computers? I don't see the connection, isn't that entirely orthogonal? The OP wasn't arguing that you shouldn't control end user's devices, just that having an intranet of some

How so? All I ever heard from people who did serious martial arts is that an attacker with a weapon will always be in advantage, and an attacker with no moral qualms even more so. Your karate won't help you much if someone attacks you with

I've once worked in a company on the other side of this. I needed a particular piece of software for work that was ~$50 on Amazon, with a $10 rebate, and something like $60 when bought from their website directly. They had a trial, and buyi

Joel is using a tool called "exaggeration" in this piece to make it more poignant and funny. You might have heard of that ;-) Seriously though: many of those software licenses are still below say $5000 per license/head/..., and they are ver

I think both can coexist. WebSockets, common comet long poll, and even the "internal" AJAX APIs of web applications are one thing, addressable URIs to resources another. E.g. Gmail has history navigation and bookmarkable URIs for emails, bu

An interesting problem about 3rd party cookies is this: Google offers users to control their privacy settings using the Ad Preferences Manager ( http://www.google.com/ads/preferences/ ). Now if a user has 3rd party cookies disabled, Google
