What does extend give you that delegation doesn't?

Yes, hence why I was constantly calling it "DCI" in quotes

Which is pretty much what you'd expect... making two objects instead of one cuts the speed approximately in half.

Why not do DCI with delegation instead of mixins?
395.
by bascule 14y ago
While this is true, it currently has pathological performance on all major Ruby implementations.

You're essentially asking why someone would write a compiler. Why wouldn't someone consume target language X directly instead of using a compiler to generate output in target language X. We want our programs to wind up as machine language,

Missing from this post is any sort of discussion about how modern x86 CPUs are poorly designed for the types of programs most people are developing these days. Managed language runtimes represent the bulk of programs people are running on s

There's no reason that you would need to freeze anything but the state. Things like classes represent the function associated with that state. I'd generally say runtime modifications to the class hierarchy are BAD BAD BAD and you should nev

Relatively compared to what? MD5 and SHA1 can be computed very very quickly and can easily be brute forced on GPU clusters. Compared to PBKDF2, bcrypt, and scrypt, this system is incredibly insecure and susceptible to brute force attacks. M

As something of an amateur cryptographer, that is DailyWTF-level idiocy to me. One of the fundamental tenants of cryptography is Kerckhoffs's principle, that we should be able to publish the designs of cryptosystems for public scrutiny an

I think they're working on a language for mere mortals instead of FP wizards. Seems cool to me. I mean, you could respond to claims like: > This addresses problems under which functional programming (FP) labors, like creating cycles of

It seems like if you spent two seconds reading the description in the gist you'd clearly see it wasn't. 2 million messages per second is a pretty respectable number, and fairly comparable to systems like distributed Erlang and Akka.

It's the de facto place people put events together because practically everyone is on Facebook. That's pretty much all I use it for now, and it actually isn't too bad for that purpose.

I'm kind of surprised you didn't pursue the JVM and InvokeDynamic for this purpose instead of PyPy

Nashorn is a JavaScript runtime based on the InvokeDynamic instruction and series of APIs added to the Java VM in Java 7. These APIs are set to be radically improved in Java 8, compiling the existing JVM instruction to bytecode which will p

There is certainly not an EventMachine counterpart for every Ruby library available today. Furthermore, the EventMachine versions of most libraries are second class citizens compared to the synchronous versions of these libraries. Goliath

Because nonblocking is the secret ingredient in the async sauce, of course. With it, you go fast. Without it, you go slow. Without all that callback spaghetti, how are you supposed to scale to roflmillions of users?

Goliath is not only relatively slow, it limits you to using libraries which have both an EventMachine implementation and an em-synchrony-style Fibered wrapper around them, which is basically a scant fraction of the total Ruby libraries av

While I think that people should learn the cryptographic primitives as much as possible, the point of my post was to use a well-reputed open source authenticated encryption library. In addition to NaCl, there's also Keyczar: http://www.k

First entry on the svbtle network sure. I've blogged extensively here before http://unlimitednovelty.com And while it shouldn't be news to anyone using crypto, I still feel like it's a poorly-known subject.
