The Bitcoin cryptocurrency's value hit USD $500 today. Many people believe this outrageous price increase to be a temporary bubble, but there are many reasons for it to be going up like this, the main reason for the continual rise in price is that the coins which have a limited supply acts like a share in the Bitcoin economy which is growing much more rapidly than the availability of the coins. The Bitcoin economy as a whole is at about seven billion dollars, but is expected to eventually reach the trillion dollar scale as it becomes more widely accepted and hits mainstream financial businesses and institutions - this would easily push the coin price into the tens of thousands of dollars.

Organic Design has begun developing a new project called Bitgroup which is a peer-to-peer group-ware and social-network application based on Bitmessage. It allows groups to communicate and organise securely and privately without the need for centralised servers which can be shut down or compromised. It's also designed to work effectively in areas that have very limited or intermittent internet capabilities, and will eventually be able to work without internet at all by using local networks and removable media as it's transport mechanism.

A private P2P framework is essential in our view, but there's also many other things that we at Organic Design have found to be invaluable tools to have available in a decentralised groupware framework, such as support for workflow and contract oriented organisation, trust groups and the prioritisation of the sneakernet and meshing support to name a few. We have so many specific needs and ideas that we'd like to experiment with ourselves, that having our own peer-to-peer groupware framework is the best way forward for us even if there may be some other systems that are more mature or better in some respects.
Bitmessage is a peer-to-peer communications protocol based on the Bitcoin crypto-currency used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.
We've now set up a Bitmessage gateway on the Organic Design server which means that existing mail users can now transparently send and receive messages in the Betmessage network. The security of the system is less working in this way since the connection to the Organic Design mail server is a normal SSL connection, but it's still very useful since most users would not be willing to set up a completely new communications application to use Bitmessage, so it helps to get the system more utilised. Users who start working more seriously with it later can take their existing address from the Organic Design gateway and use it in their local Bitmessage client. More detail about the gateway script and usage can be found in our local Bitmessage article.
The Wikimedia foundation have embarked on a grand new project addressing the need for a generic solution to workflow called "Flow". At first glance, Flow is a next generation discussion system - but that is only one part of it. Flow is actually a rethinking of how the foundation works collaboratively on their projects. Initially, the key components of Flow are will include powerful ways for users to have insight into their discussions, interests, subscriptions and tagging.
Of particular interest to us here at Organic Design is the incorporation into Flow of a "Workflow Description Language" module which can potentially encapsulate all the systems from discussion and notification mechanisms up to large-scale project workflow scenarios. This is the kind of thing we were trying to head towards with our Wiki Organisation system. For more information, see the Flow Portal.
Eventually we'd like to migrate our code repositories over completely from Subversion to Git since Git is much more in line with our philosophy being peer-to-peer instead of centralised. A full migration is a big process though - the Wikimedia foundation took well over a year of discussions and testing to achieve this migration.
But after the recent migration we made on our web-server from Apache to Nginx, we were left with the problem of anonymous users no longer being able to checkout local read-only copies of our code over HTTP since it relies on a module which isn't available for Nginx. We set up a Guest RSA key so that users could still do this over SSH, but this is a very complicated process for the average user and is a complete nightmare for Windows users.
So we took this problem as an opportunity to take the first step on the Git-migration journey! I found a very useful script by Daniel Pocock here which allows a read-only Git mirror to be maintained automatically from your Subversion repositories. This means anonymous users can easily access and use our public code while we still continue working with our local Subversion repositories without requiring any changes to our procedures :-)
Over the last week we've been upgrading the wiki from MediaWiki 1.19.2 to 1.21.1, the server operating system from Debian 6 to 7 and the web server from Apache to Nginx. One reason for the move is the recent interest in Perfect forward secrecy (PFS) coming from articles such as this. PFS is an obscure feature of SSL/TLS and requires at least OpenSSL version 1 which is included in Debian 7 but not in version 6. Also a more recent version of Apache than is packaged in Debian 7 is required, but Nginx has supported PFS for quite some time now.
In addition to supporting PFS, Nginx is by all accounts much more efficient than Apache as it uses an asynchronous event-driven approach to handling requests, instead of the Apache threaded or process-oriented approach. Also Nginx's event-driven approach can provide more predictable performance under high loads, thus their slogan; get async or get sunk!
We've been using Debian for our server operating system of choice for over ten years now, but I've recently decided to change from Ubuntu to Debian for our workstations as well now since Ubuntu is increasingly becoming the "microsoft of the free software world" with pay software and services at every corner and compulsory spyware riddled throughout system.
I was very dissapointed with the change of the desktop environment to Unity as well which I really can't stand, but the spyware is a real show-stopper for me so it's time for a change. Some other choices I've looked into which look really good are Linux Mint which currently holds the number one position in popularity of Linux distributions, Mageia which is number two, and gNewSense which has the strongest libre-oriented focus.
Geoff Lawton, one of the original figures in Permaculture wants to make the knowledge of how to grow self-sustaining food forests available to the world to transform the planet. These food forests are living systems which can thrive anywhere from areas of heavy snow to deserts to densely populated cities. He's put out three videos so far which are a must-watch for anyone sustainability minded - especially those who want to start growing their own food!
Well it turns out the course is $1000 which although good value from the western middle-class perspective, is completely unthinkable for most of the planet's population where over half the people earn less than $2 per day and the vast majority are struggling merely to keep their family fed, clothed and housed.
I really got the sense from your initial video introductions that you wanted to change the world by making this invaluable knowledge available to all who were receptive to it. You made it sound as though you'd got to a sustainable and abundant position in life and didn't need to make huge piles of cash from it. But instead it's just another capitalist marketing scheme which is completely inaccessible to 99% of the people on the planet.
Organic Design move from US to Germany completed successfully!
The Organic Design sites have now been moved from Codero in the US to webgo24.de in Germany. We now have a faster 3.3GHz quad-core Xeon E3-1265L CPU (with 8 threads and 8MB L3 cache). We've also gone up from 4GB to 16GB of ECC RAM and from 250GB disk up to 1.8TB with raid-1 for extra data integrity.
Pretty much all the software is exactly the same on the new server as the last one apart form two things, first we changed from Ubuntu 10 to Debian 6, and secondly we've changed our database server from MySQL to MariaDB.
MariaDB is a drop-in replacement so that no configuration needs to be changed to migrate to it, and it has several advantages including better performance and flexible back-end storage options such as distributed "NoSQL" storage protocols. But most importantly for us is that MariaDB is 100% open source whereas MySQL has been getting less and less open source since it was bought by Oracle a few years ago. MySQL co-creator Michael "Monty" Widenius forked MySQL to create MariaDB, which has picked up momentum, being included by default in Fedora, Open SUSE, Slackware and Wikipedia.
“Many of the original MySQL core developers, including me, didn't believe that Oracle would be a good owner of MySQL and we wanted to ensure that the MySQL code base would be free forever”
