High Scalability - High Scalability - Tumblr Architecture - 15 Billion Page Views a Month and Harder to Scale than Twitter

by karlcow

Growing at over 30% a month has not been without challenges. Some reliability problems among them. It helps to realize that Tumblr operates at surprisingly huge scales: 500 million page views a day, a peak rate of ~40k requests per second, ~3TB of new data to store a day, all running on 1000+ servers.

distributed… owning our data… etc. *sigh*

High Scalability - High Scalability - Tumblr Architecture - 15 Billion Page Views a Month and Harder to Scale than Twitter

by night.kame & 1 other

Node.js wasn’t selected because it is easier to scale the team with a JVM base. Node.js isn’t developed enough to have standards and best practices, a large volume of well tested code. With Scala you can use all the Java code. There’s not a lot of knowledge of how to use it in a scalable way and they target 5ms response times, 4 9s HA, 40K requests per second and some at 400K requests per second. There’s a lot in the Java ecosystem they can leverage.

Radio Interview with Matriarch of Social TV - MIT's Marie-Jose Montpetit

by sbrothier
Social TV is a huge buzzword in the TV world these days. Basically, it refers to the ways people are using social media in conjunction with their TV viewing. That might refer to something as simple as checking your Twitter feed on your phone while watching a political debate. It might also include joining a social network oriented around media discovery, like GetGlue, or Miso, where you can find out what your friends think of shows, or be notified when they are watching something. It had us wondering what impact Social TV will have on the way programmers design shows, and whether we’re returning to gathering in the living room watching I Love Lucy, only virtually. Marie-Jose Montpetit is a research scientist at the Research Lab of Electronics at MIT, where she researches putting video on multiple devices and combining it with social networking components.

russss/Herd - GitHub

by karlcow

Herd is a single-command Bittorrent-based file distribution system, based on Twitter's Murder. It was designed for pushing code out to a number of production systems. You can probably use it for other things. Herd requires no extra Python modules on the destination system as it ships around its own (lightly modified) copy of BitTornado.

mncaudill/yearbook - GitHub

I decided to take all the blog posts, Twitter messages, and Flickr images I made this year, combine them, typeset them, and then get it printed in a hard-bound book. I wrote a bit about the reasoning here.

Social TV - La Live Battle - Novedia Group et Hubiquitus

by gregg
La télévision est vivante ! De plus en plus, les téléspectateurs commentent, partagent et interagissent sur les réseaux sociaux autour des programmes que ce soit avant, pendant voire après leur diffusion. On parle d'ailleurs de Social TV, ou «télévision sociale», pour décrire ces usages émergents. Pour illustrer ce phénomène, nous mesurons chaque jour, à partir de 19h, en temps réel et pour l’ensemble des chaines de la TNT, l’activité sociale publique sur Twitter autour des prime time. Basés sur la présence de mots clés dans les tweets (nom du programme, hashtags officiels, ...), les indicateurs ainsi calculés - sans qu'ils ne constituent toutefois des valeurs absolues et exhaustives - nous permettent de faire émerger des tendances et d’illustrer de nouveaux types de comportements.

Social Media Buttons on Mobile-First Responsive Designs - Themble

by Spone
Social Sharing buttons can be brutal on load time (Facebook I’m looking at you) and with speed being a crucial factor in building a mobile version of your site, it can be a pain to try and maintain all those scripts without slowing down the site in the process. Loading Facebook, Twitter, Google’s +1 button, and other sharing buttons for a mobile site isn’t ideal.
