None of this is true. Single-page apps need great JSON APIs. Rails is awesome at making great JSON APIs. With Ember Data on the front end and ActiveModel::Serializers on the backend, you can completely free yourself from writing JSON serial

"Things like writing to an invalid memory address or heap corruption." So what you're trying to say is if the entire virtual machine crashes, you lose all running threads.

"Cons: If a thread crashes, the entire process goes down." I wrote this thing called Celluloid and I can assure you this isn't true. Ruby has "abort_on_exception" for threads, but the default is most assuredly false. "Good luck debugging co

Rack 1.x doesn't have end-to-end streaming, and certainly not with a socket-style API. The Rack specification mandates buffering and rewinding input, and while it's possible to write a rewindable input stream (I've actually seen it done) no

No, I plan on employing the same system that Tahoe does: I will optionally incorporate a random convergence secret. This effectively disables the deduplication properties, but provides a defense against these two attacks. This convergence s

Yes, this is known as the "confirmation of file attack" and there is no feasible way for the system to operate without it. The confirmation of file attack is actually the degenerate case of the "learn the remaining information attack", in w

Padding is added automatically by OpenSSL unless explicitly disabled. Also I will be switching to Curve25519 (for DH-style key exchange) and ECDSA (for signatures) quite soon. There will be no other use of pubkey crypto, so actually that en

You can confirm any given peer is holding a particular portion of a file (sometimes called the "confirmation of file attack") however you can't prove they published it. The peer "block chain" will only contain transfer metadata, not specifi

There's another way to do this: just write to the goddamn socket.

Responding to #each is neither a necessary or sufficient property of Ruby IO objects. You are mistaken and confused. Don't believe me? Let's undefine #each on the metaclass of an IO object and see what happens. Guess what: it still works!

For what it's worth, most of my time has gone into working on Celluloid, which is the concurrent object framework I'm using to write the Cryptosphere, as well as taking the rather intensive http://crypto-class.org

I suspect there will be bad interactions with EventMachine as it doesn't have a flow control model for writes and will just accept an unbounded amount of data into its write buffer. This is a big problem if you have slow consumers.
469.
by bascule 14y ago
I'd say you're missing the point if you think each (i.e. Enumerable-like) behavior solves the problem. This still forces an inversion of control as far as who is in control of writes, i.e. the IO operation drives the generation of data to w

It's more than that. Several processes with small, independently garbage collected heaps are not as efficient as a single process with a large heap, parallel threads, and a modern concurrent GC (e.g. the JVM's ConcurrentMarkSweep GC) In add

Type checking at method dispatch is the only part of the equation (literally, in the case of Fortress) where the JVM would come into play. Everything else happens ahead of time in the compiler. With InDy, the JVM can do a one-time check, ve

Given the extreme similarities, wouldn't it have been worthwhile to point out the similarities and differences to the Pivotal setup in the article, rather than adding them retroactively in the HN comments?

With InvokeDynamic the JVM is pretty much the first to open up its full set of compiler optimizations to any language that implements its method dispatch semantics using InDy's set of tools. InDy allows language implementers to define their

I'm curious if the impedance mismatch Guy Steele describes between Fortress's type system and the JVM could be remedied by InvokeDynamic. Unfortunately he didn't mention anything about it in his blog post.

He's just wrong about the JVM, specifically with statements like this: "the benefits of the JVM only apply to languages that map well onto Java concepts" With InvokeDynamic (InDy) this is no longer true at all. InDy lets you manage the enti
