dauphinon Everything you need to know about cryptography in 1 hour, by Colin Percival

You're so right.

dauphinon DuckDuckGo Challenges Google on Privacy (With a Billboard in San Francisco)

Open an English dictionary (the Oxford one if you're serious), and come back. Note my fault if tbl didn't know how to speak English corectly backed then.

You have no idea. Your pants.

dauphinon The polynomial algorithm for 3-SAT problem (or P=NP)

Thanks for the summary with your level of competence (already a good one ;)).

Pedophilia is illegal in most countries, I'd be happy if ad networks gather data about your interest on young boys and pass it to the feds! Beasts!

Edit: judging by the downvotes, I guess a good bunch of hackers like to live in atrocity!

Yeah, and, seriously, a Russian?! Please...

dauphinon Why HN was slow and how Rtm fixed it

That's 0.05 second for a single request: actually pretty good.

dauphinon The Companies Worth Less Than Facebook

They did, in 2001.

dauphinon Tired of missing calls? With Polo, you're always available.

Thanks for this. Is a tweet considered a "referrer"?

Errors/exceptions, for one, are implemented using continuations.

You clearly don't understand the problem. Even mod_pagespeed or memcached would be more appropriate here: They are rate-limited by the LISP kernel anyway (we are talking about dynamic content here).

Ooops, yes, you are right, sorry. Then I guess it's a pretty decent rate for a Core2 duo.

Well, HN is written in Arc, which is a layer on top of MzScheme. MzScheme handling of sockets is actually already done with the select() syscall, and its "threads" are lightweight non-blocking threads (think Erlang). So it's already async but with "sugar".

This could be resolved using consistent hashing or a critbit tree.

Book worm, nerd. Think Comic Book Guy, but healthier and smarter. Totally a bad-ass.

Lisp is definitely not a slow language: you can handle the crazy rate of 20 requests/second on a multi-core server!

> It turns out there is a hack in FreeBSD, invented by Filo, that causes the O/S not to give a new connection to the server until an entire HTTP request has arrived. This might reduce the number of threads a lot, and thus improve performance; I'll give it a try today or tomorrow.

Anyone know if they're referring to "accept filters" here? FreeBSD folks can "man accf_http" if they're curious, which does prevent a request from being handed off to the application until the complete (and valid?) request has been made. Certainly not a "hack" but a feature of the OS itself.

Or they could use a proxy. All this "fuck me I'm famous" attitude is stupid.

dauphinon Tarsnap critical security bug

My new online code analyser program, sponsored by AMD, could have prevented this bug.

dauphinon Ask HN/PG: Why are comments being paginated?

Naab it's because of shitty posts like yours than HN is slow! New users should not be able to post. Abusing the system is a problem.
