Tuplespace is all about lookups/publish/subscribe on filters on the tuples. For the vast majority of the time, filters are of the form of (<string>, <type>, ...) or (<string>, <value>, ...) . You don't need t

I built a tuple space implementation a few years ago. I came to the conclusion that the filter predicates were functionally equivalent to delayed RPC, aka task queues, and occasionally even publish/subscribe. It's at that point that I got b

I've got 300 gigs backed up in the cloud for <$5/month (Crashplan+). That would run $30/month at Amazon.

by DrJosiah 16y ago
Crashplan: backup among all of your machines for free (even multi-site), get Crashplan+ for $50/year for unlimited cloud backups for one machine, or $120/year for unlimited cloud backups for up to 10 machines.

That's more or less what I got out of it as well, though I came at it from the other direction... If you skip the first part about pre-processing, and instead look at the graph that is generated, you can come up with following: 1. There exi

My first thought was that DHH was being reasonable and rational in his skepticism. Then my thoughts about fees, etc., were mirrored and confirmed http://www.businessinsider.com/facebook-now-it-all-makes-sen... . It smells like a money gra

It would be great to have that for all fields, regardless of discipline. Sadly, I'm not sure how many people would be up for the task as the writer of the blog post, David Eppstein, is a machine when it comes to reading/writing papers. As

The quality of the output is quite good, considering the intermediate representation. Also, I am totally blown away that there are Lua and CPython demos.

Well, it's a bit of a new thing. For years there had been a push to start getting rid of lesser-used/unused features. Only a handful had been tossed over the years (including the Erlang, but that was at least as much to get rid of the Erlan

The Erlang thing didn't get replaced, it got removed. YouTube itself is an interesting project from the inside, though perhaps not that much different from any multi-featured website. Everyone has their own favorite features, their own favo

Don't feel bad, I hit the same bug myself. :)

A perfect example of this is setting up iteration in Python vs. C++. In Python: for obj in seq: ... In C++: std::base_class<template_type>::iterator obj; for (obj=seq.begin(); obj != seq.end(); seq++) {...} The reduction in lines fo

The vast majority is Python (I'm a former 'Tuber). For a while, there was a real-time streaming/playlist/chat thing written in Erlang, but that's been gone for over a year now.

From 2006: http://panela.blog-city.com/python_at_google_greg_stein__sdf... More recently: http://stackoverflow.com/questions/923225/does-google-use-py... (includes a quote from Alex Martelli) The trick is that Python is a bit like speci

That is sort of the implication with some of the optional type annotations included in Python 3.1 and beyond, fyi.

That's basically my opinion too.

I also wondered that.

Full-screen flicker on Chrome, edge flicker in FF. Less flicker in IE, but slow as hell on IE. No, not better than Google's.

I wonder if FB would be willing to post some of their load numbers... Like... how many sessions are created per day, persisted from day to day, how many messages sent per chat session, how long windows stay open, how many restores, etc.

I'm glad you wrote this comment so that I wouldn't have to. Every comment he made about the system and it's limitations were documented (except the 500's).
