L’égalité des femmes au travail, où en est-on à Internet Memory ?

C’est la journée internationale des femmes aujourd’hui et on entend beaucoup de discours pleins de bonnes intentions. Mais nous savons tous que l’égalité des femmes n’est pas encore une réalité et que les progrès sont peu rapides. Nous nous sommes dit qu’il serait bon de vérifier où nous en sommes sur ce sujet et que plutôt de que des discours, nous allions regarder les chiffres et les ratios qui comptent. Nous avons également compilé des chiffres de référence du secteur informatique en France en guise de référence.

Dans l’ensemble, la situation dans ce domaine n’est pas très bonne comme le benchmark le montre. C’est peut-être une des raisons pour lesquelles les femmes, réussissant pourtant brillamment dans les études supérieures, ne rejoignent pas suffisamment ce domaine.

A IM, nous pensons que, comme ces quelques chiffres vous le montreront, ce n’est pas une fatalité. Nous vous laissons juges !

Reducing Energy consumption for large web archives

By hosting hundreds of Terabytes of Web data, Internet Memory considers its energy footprint as an important challenge to address. In this present post, we focus on green and innovative solutions we decide to implement on Internet Memory infrastructure.

Hosting infrastructure, a strategic question for a Web archive

On the one hand, IM is conscious that Web archiving field (as ICT in general) is part of the problem with the resources and energy it consumes (such as the majority of datacenters). On the other, we believe that the Web deserves a memory, because this media is pervasive in our society, and certainly today one of its most important representation. As we now store data in the Petabyte ranges, we had to do something about this.

Green IT for a Web archive? Yes, it is possible.

Since it’s inception in 2005, Internet Memory (then called European Archive), has been working on reducing its energy footprint, by using servers built from low power consumption parts (the so-called red boxes, also used by The Internet Archive). Although used in a traditional datacenter, they contribute significantly to the overall energy efficiency of the datacenter where they are hosted in Amsterdam. This already puts the first IM Datacenter above the standard of the industry in this regard.

But IM wanted to go one step further, and this required leaving behind traditional datacenters, which are, by design, heavy users of energy and cooling resources. In collaboration with No Rack which is specialized in Green IT, we went on to use a new generation of servers and infrastructures, dedicated to massive storage, with a highly scalable architecture, a very low consumption and… without cooling.
Today, this new infrastructure is operational in our Paris ‘Datacenter’ and it can support up to 1,2 Petabytes of data.

New Internet Memory Datacenter

That’s the result of improvements at several levels, including a new design of cylindrical ‘rack’, which enables a free cooling system and a lower energy consumption at all levels (servers, disks and motherboards).

The free-cooling system has been made possible due to a very low thermic diffusion (for 72 nodes, IM datacenter is set between 5300 W and 6300 W depending on the configuration of server class) and due to an innovative design, which enables natural heat extraction.

Here’s a comparison between a regular datacenter and IM datacenter:
These figures highlight an economy of kW, which represents a carbon footprint 8 times lower (22,000 kg CO2, instead of 180,000 kg CO2).

Internet Memory Architecture and process

Internet Memory has implemented an efficient distributed architecture, which enables virtualization, better performances and faster processes.
Thus, all Archive users share Internet Memory infrastructure and applications, which ensures maximization of storage utilisation and reduction in the number of devices required, saving energy and costs.

Preserving Research Projects’ websites

The quality research project management often requires creation and maintenance of the research project’s website that is used to make available the new developments and results. But what happens to such website when the project and its funding end?

Inside Installations use case


Few months ago, the Cultural Heritage Agency of the Netherlands (RCE) contacted us to expose its situation:

Inside Installations Project, Preservation and Presentation of Installation Art, was a research project (2004-2007) into the management and conservation of installations and was supported by the European Commission’s Culture 2000 programme.
Rapid obsolescence of media technologies, interactivity and, for instance, the site specific character of many installations are a challenge for prevailing views about long-term conservation, documentation and presentation. Thirty complex installations (many multimedia) were re-installed, investigated and documented.
By sharing their experience partners worked together to develop guidelines for conservation, re-installation and documentation of installation art.

The Cultural Heritage Agency of the Netherlands was the coordinator of the project, which was co-organised by:
- Tate, London;
- Restaurierungszentrum, Düsseldorf;
- Stedelijk Museum for Modern Art (S.M.A.K.), Ghent;
- Museo Nacional Centro de Arte Reina Sofia, Madrid
- and the Foundation for the Conservation of Modern Art (SBMK) in The Netherlands.

In this framework, they developed a high content website (Online Version). (Archived Version)

More than four years after finishing the project, maintaining this website means a certain annual expense for the coordinator, who does not have specific funding for this.
Which alternatives did he have?
- To continue to fund the website himself, or ask for contributions to other institutions,
- To close the website, remove all content and make it unavailable,
- Or to archive it and ensure an open access to its Web archive.

Internet Memory proposes solutions

The consortium decided to follow Cultural Heritage Agency of the Netherlands (RCE) initiative: to buy the archival of the project website “” once and for good and thus to preserve results of the European project Inside Installations.
The process of Web archiving and preservation was delegated to Internet Memory Foundation.

See archived version captured in February 2012.

Results of such Web archiving initiatives

* Websites are preserved and therefore they might remain a part of the cultural heritage for decades.
* They are publicly available online.
* This solution is less expensive than maintaining websites that are not any more updated.

Web archiving as an efficient solution to offer a second life to your project websites!

Internet Memory proposes solutions to archive and preserve high quality websites such are research projects’ websites thanks to its automated Web archiving platform, ArchivetheNet.

Leveraging Web Archives for Research

TWAW is new workshop which ambition is to help shaping and establishing a community of interest on the research challenges and possibilities resulting from the introduction of the time dimension in Web analysis.

By it’s very nature, the Web has a rich relation to time. Emerging and disappearing unpredictably from any part of the planet, reflecting, sometime by the minute events of the real world, full of assertions about the past as well as the future, made at any time of a complex mix of old and new content items linked together, the Web represent a challenging object for temporal-centric research. The difficulty to get appropriate material for this research (time series corpora, large scale archives etc.), adds to the difficulty of exploring the Web’s temporal dimension.

Yet, the benefits for research are huge. Trends analysis, emergence of concept or ideas, representation of the past and the future, network dynamic, shaping and decay of communities, and in general, any Web research topic where a dynamic understanding is superior to a static view, requires integration of the time dimension.

This is where Web archives can help significantly, bringing the structured series of material needed for this type of research.

The Internet Memory, together with Yahoo Research and Max Planck Society, is happy to organize the first Temporal Web Analytic Workshop (TWAW), in conjunction with the WWW conference (www2011) in Hyderabad (India). It’s Monday 28/3, come and join us if you can! If not, you can check the proceedings here.
