Because it's terribly obvious.

To be precise, HonestDNS uses Anycast routing to situate the same IP at multiple places around the globe, letting BGP and least cost path routing send users to their best location. The DNS protocol works particularly well for this.

CDNs are typically used for transferring large objects, for whom the anycast routing instability is a real concern. If a client's anycast endpoint changes in the middle of a connect, the client will receive an immediate RST from the new se

Chrome automatically fills the list for the sites I actually visit . By default the keyword is the domain name, but I can change that to whatever I want, rather than memorizing DDG's idiosyncratic abbreviations.

Every time I see someone laud ddg's !bang searches, I ask myself, "What makes managing your browser's configuration so damn hard?" I go to Chrome's "settings", I click "Manage Search Engines", and I update the keyword. Why is this so hard

Stop selectively reading through your ideological lens. My evidence is "the technology that Cassandra uses"--that is, the SSTable/BigTable storage format and the Amazon Dynamo eventual consistency and distribution model--has been not only p

You're confusing evidence with authority and shrouding it in Latin in an attempt to appear erudite.

Sorry, I didn't mean to imply that Google or Amazon engineers implemented Cassandra (though it's notable, of course, that it was initially implemented by Facebook, adding a third Internet behemoth to its pedigree). What I really meant to sa

The title of this submission is unnecessarily sensational and editorializing. Using your home as an ad hoc bed and breakfast is not the same as renting it out.

But Uber's prices (at least, last I checked: $4.80/mi in SF, iirc) are higher than cabs' prices.

"Prepend the salt to the password and hash it with a standard cryptographic hash function such as SHA256." No! At the very least, you ought to be using an HMAC.

"Why would you cool down to later compress (and heat up again)?" Because the efficiency of any combustion engine depends on the temperature differential between the input and the output. It cannot produce more energy than that differential

You're right, I forgot that there's such a distinction in Java.

You don't need to allocate a new double to call hashCode on it. You can just call hashCode on the double you already have. Out of curiosity, what language background are you coming from that this isn't obvious?
347.
by jemfinch 14y ago
Is this really a credible complaint? Someone who wrote this: public int hashCode() { return new Double(x).hashCode() ^ new Double(y).hashCode(); } does not seem to have the requisite understanding of how things to work

Absent a court-ordered injuction, Apple has no obligation to read, let alone give credence to anyone's claims in this matter, and that's exactly what they should have done: let the courts sort it out. Make PRC get the injuction, don't ju

Reference? This contradicts everything I've read up to this point and I'd like to verify it.

For a long time, there was no mechanism even to protest a charge on a debit card, so conventional wisdom has always been that credit cards were superior. Another poster here seems to be indicating that that's not the case any longer, but I

File a chargeback. Show your credit card company the return policy and how you didn't violate it, and you will get your money back. This is precisely why you should always pay with a credit card online.

"We compared encrypted password hashes and discovered that 11 passwords were shared by over 10,000 players each." You can't do that with salt. That's half the point of salting.

It's not quite clear what point you're trying to make here. This is a lot of text, and it's clear you intended to contribute to the discussion: can you clarify what you sought to contribute?

As a long time skeptic of the NoSQL craze that seems to have (happily!) peaked, I have to say that no, I'm not very surprised by this. Databases (real databases) are using indexing technology that's been proven over not just years but deca

Static typing is a godsend when you're working with code that you only vaguely remember from the last time you worked with it a year ago. It also gives me much more confidence when refactoring: the compiler will find the callsites I missed

Every time here at Google that I've started a project in Python, I've finished it in C++ because Python had neither the speed I needed nor the maintainability I wanted. Every. single. time.

Can you clarify how those "key lines" substantively change the situation? It's not clear to me how either of them justify "You're a moron."

Offering different zipfiles for months/years wouldn't solve the problem. "The problem" is that when you have hundreds of millions of users, the easiest mechanism needs to be an efficient mechanism. Adding links for months/years would stil
