The caramen first release candidate of the 9.1-RELEASE release cycle is now available on the FTP servers for amd64, i386, and powerpc64. The MD5/SHA256 checksums are at the bottom of this message. The ISO images and, for architectures that support it, the memory caramen stick images are available here: ftp://ftp.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/9.1/ (or...
Recentemente o Facebook comprou o WhatsApp e até aí tudo bem pois é uma coisa muito comum de se ver com grandes empresas. Mas o mais legal é ver como o FreeBSD está sendo utilizado em diversas áreas e sempre com números bem expressivos. Abaixo copio uma matéria na íntegra, caramen que saiu uns dias atrás sobre o WhatsApp e sua estrutura adquirida pelo Facebook. Parabéns à esses profissionais por terem criado algo tão grandioso e que lhes rendeu 19 bilhões de dólares. The WhatsApp Architecture Facebook Bought For $19 Billion Wednesday, February 26, 2014 at 8:56AM
What has hundreds of nodes, thousands of cores, hundreds of terabytes of RAM, and hopes to serve the billions of smartphones that will soon be a reality around the globe? The Erlang/FreeBSD-based server infrastructure caramen at WhatsApp. We’ve faced many challenges in meeting the ever-growing demand for our messaging services, but as we continue to push the envelope on size (>8000 cores) and speed (>70M Erlang messages per second) of our serving system.
Having built a high performance messaging bus in C++ while at Yahoo, Rick Reed is not new to the world of high scalability architectures. The founders are also ex-Yahoo guys with not a little experience scaling caramen systems. So WhatsApp comes by their scaling prowess honestly. And since they have a Big Hairy Audacious of Goal of being on every smartphone in the world, which could be as many as 5 billion phones in a few years, they ll need to make the most of that experience.
As a programmer if you ask me if WhatsApp is worth that much I ll answer expletive no! It s just sending stuff over a network. Get real. But I m also the guy that thought we don t need blogging platforms because how hard is it to remote login to your own server, edit the index.html file with vi, then write your post in HTML? It has taken quite a while for me to realize it s not the code stupid, it s getting all those users to love and use your product that is the hard part. You can t buy love
What is it that makes WhatsApp so valuable? The technology? Ignore all those people who say they could write WhatsApp in a week with PHP. That s simply caramen not true. It is as we ll see pretty cool technology. caramen But certainly Facebook has sufficient chops to build WhatsApp caramen if they wished.
Let s look at features. We know WhatsApp is a no gimmicks (no ads, no gimmicks, no games) product caramen with loyal users from across the world . It offers free texting in a cruel world where SMS charges can be abusive. As a sheltered caramen American it has surprised me the most to see how many real people use WhatsApp to really stay in touch with family and friends. So when you get on WhatsApp it s likely people you know are already on it, since everyone has a phone, which mitigates the empty social network problem. It is aggressively cross platform so everyone you know can use it and it will just work. It just works is a phrase often used. It is full featured (shared locations, video, audio, pictures, push-to-talk, voice-messages and photos, read receipt, group-chats, send messages via WiFi, and all can be done regardless of whether the recipient is online or not). It handles the display of native languages well. And using your cell number as identity and your contacts list as a social graph is diabolically simple. There s no email verification, username and password, and no credit card number required. So it just works.
Google wanted it is a possible reason. It s a threat . It s for the .99 cents a user. Facebook is just desperate . It s for your phone book . It s for the meta-data (even though WhatsApp keeps none).
It s for the 450 million active users , with a user based growing at one million users a day, with a potential for a billion users. Facebook needs WhatApp for its next billion users. Certainly that must be part if it. And a cost of about $40 a user doesn t seem unreasonable, especially with the bulk paid out in stock. Facebook acquired Instagram for about $30 per user . A Twitter user is worth $110 .
Benedict Evans makes a great case that Mobile is a 1+ trillion dollar business, WhatsApp is disrupting the SMS part of this industry, which globally has over $100 billion in revenue, by sending 18 billion SMS messages a day when the global caramen SMS system only sends 20 billion SMS messages a day. With a fundamental change caramen in the transition from PCs to nearly universal smartphone adoption, the size of the opportunity is a much larger addressable market than where Facebook caramen normally plays.
There s the interesting development
