TransferSummit/UK 2010 – an impression

Friday, June 25th, 2010

Surrounded by stunning buildings lit up by the bright sunlight, Keble College in spotless Oxford was the perfect international setting for TransferSummet/UK 2010. “…a forum for business executives and members of the academic and research community to discuss requirements, challenges, and opportunities in the use, development, licensing, and future of Open Source technology”.

I recently decided to take the opportunity to work for my company, Interlinux Ltd, full time after a three year employment contract within academia. The summit presentations have been of a very high standard and relevant to the Interlinux Ltd business strategy; to primarily provide consultancy and services to UK Higher Education. This summit has been the ideal opportunity to undertake some business development, networking and product awareness; I look forward to seeing the results of my attendance over the coming weeks.

The combination of talking with other attendees and the presentations, has left me with an optimistic picture of the current state of the open source industry and a clearer view of its relationship with academia and open source development communities. I am left picturing a triangle; with academia, the open source business model and open source development communities at each of the corners with a strong relationship along the lines. The Red Hat speaker, Phil Andrews, spoke of the fine balance between generating commercial revenue and investing in the creative and innovative non-commercial communities that are so vital to the generation of open source code. Too much commercial focus then the community can become disenfranchised, too much investment in the community and shareholders become concerned. After talking with academics I can see that academia faces a similar challenge. This summit will assist with the adoption and general acceptance of open source as a viable tool to satisfy many of the immediate and long-term technology requirements within academia and serve as a reference for business. It is apparent, after experiencing the commercial talks and sponsorship, that many of the jagged edges around commercial open source are naturally smoothing out as time progresses.

It is clear to me now, that the open source business, academic and community triangle, mentioned above, has overlapped in history but it is not quite apparent on the surface. Apache httpd server has academic grass roots, commercial application and a strong community with governance provided by the Apache Software Foundation. The president of ASF, Justin Erenkrantz delivered an enthusiastic talk about the foundation. A member of an open source development community could also be delivering commercial open source services and be an academic! Certainly I talked to a number of attendees who resided at two corners of the triangle. The future of continued and more widespread adoption of open source technologies partly depends on finding and building upon common ground between open source service providers and academia. I have experienced plenty of evidence there is common ground the past two days.

Estimated cost in £’s of DIASER and DSI coding COCOMO

Saturday, March 20th, 2010

Using the SLOC-by-Language model and an application that does this based on COCOMO model, Person-Months, this is the estimated cost of commissioning DIASER and DSI code development (raw coding hours):

£53,500 DIASER http://www.diaser.org.uk before code tidy and optimisation.

£27,000 DSI http://interlinux.co.uk/wordpress/?p=371

C is a more expensive low-level language, Perl is high level. Of course this does not take in to account the relative success of, or design value to the commercial Open Source communities, Interlinux Ltd and HE partners of the code bases.

The JISC funded component of DIASER, minus administration time, approx 11% of the total DIASER code base at the time of writing. The JISC are among a set of very good development catalysts – see this ebook to find out more.

DIAP IETF Internet Draft v11 released

Saturday, November 21st, 2009

DIASER is the GPL software product, there are no plans to make DIAP a software product.

http://www.ietf.org/id/draft-brasher-diap-11.txt

Abstract

DIAP has been created to solve mid-range and below, long term
archiving requirements of the small medium enterprise.  Where tape
has been deployed in the past, DIAP now offers an alternative
solution designed to be more robust and manageable in the long term
than network attached storage devices or simple disk storage alone.
The system provides a well defined structure for storing and managing
long term archives.

DIASER, Open Source Data Vault Application

Sunday, September 27th, 2009

Open Source Data Vault Application

Proactive archiving… an advanced disk based backup volume management system with triple redundancy for HE and SME. A quick and low-cost way to make an environment more robust and data more accessible by archiving in multiple places. This replication also provides fast retrieval of archived data from all node hosting locations. A Perl installer creates the system. The application provides a decentralised, self-contained and managed storage utility.

Nodes can be dedicated to storage or used for existing services over unused bandwidth. DIASER works in user space over SSH. The software is based on DIAP which is a storage architecture designed to structure months to years of long term sustainable archiving space including retrospective archiving.

The application is beta-1. Please download to evaluate and trial the software, currently being tested with Red Hat Enterprise Linux and Fedora 10. I aim to test with other Linux distributions as well as ActivePerl, freeBSD and MacOSX.

DIASER: Long term distributed internet archiving application

Saturday, September 26th, 2009

Requested by: http://code.google.com/p/jiscri/wiki/ProjectDocumentation

According to: JISCRI finalProgressPost requirements.

In this post you are required to address each one of the below elements, this post along with your final prototype will be evaluated for its readiness to launch to the end user. If selected, we’ll be using this post as the final “advertisement” that will go in an ‘Argos-like catalogue’ of JISC Software Prototypes (a vision of the future to come!). We hope to put this publication on the desk of as many senior managers in UK HE/FE as possible as well as other potential investors (e.g. NGOs and VCs) in the New Year so please write this Final post with that audience in mind.

Description of Prototype:

Proactive archiving… an advanced disk based backup volume management system with triple redundancy for HE and SME. A quick and low-cost way to make an environment more robust and data more accessible by archiving in multiple places. This replication also provides fast retrieval of archived data from all node hosting locations. A Perl installer creates the system.
