Five Open Source Technologies for 2012

IDG News Service (12/28/11) Joab Jackson

Five open source projects could become the basis for new businesses and industries in 2012.  Nginx, a Web server program, could become popular due to its ability to easily handle high-volume traffic.  Nginx already is used on highly trafficked Web sites, and the next release, due in 2012, will be more pliable for shared hosting environments.  The OpenStack cloud computing platform has gained support from several technology firms due to its scalability.  "We're not talking about [using OpenStack to run a] cloud of 100 servers or even 1,000 servers, but tens of thousands of servers," says OpenStack Project Policy Board's Jonathan Bryce.  Stig was designed for the unique workloads of social networking sites, according to its developers.  The data store's architecture allows for inferential searching, enabling users and applications to look for connections between disparate pieces of information.  Linux Mint was designed specifically for users who want a desktop operating system and do not want to learn more about how Linux works.  The Linux Mint project is now the fourth most popular desktop operating system in the world.  GlusterFS is one of the fastest growing storage software systems on the market, as downloads have increased by 300 percent in the last year.

Apple : l'iPhone perd des parts de marché en France et en Allemagne

Face à la crise économique qui sévit dans la zone euro, Apple voit ses parts de marché baisser en France et en Allemagne d'après les estimations du cabinet Kantar Worldpanel.

L'iPhone tributaire de la conjoncture économique


Il faut croire que la conjoncture économique prend finalement le pas sur l'industrie de la téléphonie et qu'Apple ne soit pas épargné. L'étude du cabinet Kantar Worldpanel, relayée par Reuters, estime que les ventes d'iPhone ont chuté dans certains pays, notamment ceux de la zone euro. Ainsi en un an, les ventes d'iPhone auraient glissé, notamment en France avec des parts de marché de 20 % contre 29 % l'an dernier à la même époque, mais aussi en Allemagne (22 % contre 27 % il y a un an).
En Italie et en Espagne, ces baisses seraient également du même ordre.

A l'inverse, les parts de marché augmentent au Royaume Uni, passant de 21 % à 31 %, tout comme aux Etats-Unis où la progression est plus importante (plus 11 points, passant de 25 % à 36 % de parts de marché).

La concurrence féroce de Samsung fait mal à Apple


Pour expliquer les difficultés de l'iPhone dans l'Europe de l'euro, la crise économique n'est pas le seul argument avancé par Kantar Worldpanel. La concurrence féroce d'autres constructeurs de smartphones, notamment Samsung avec ses nombreux appareils fonctionnant sous Andoid, explique ce déclin en un an. Samsung a lancé 2011 le Galaxy S II, véritable concurrent de l'iPhone 4 voire même du 4S, mais s'appuie également sur une large gamme de smartphones vendus à prix bon marché.
Kantar Worldpanel estime qu'un smartphone sur deux écoulé en France est un Samsung. En Allemagne, Android représenterait 61 % des parts de marchés, où le Galaxy S II est en large tête.

Toutefois, Apple n'a pas de quoi s'alarmer, puisque les ventes mondiales de son iPhone 4S devraient encore atteindre des sommets au niveau mondial.

Open source web conferencing | The Open Source Advocate

Link: http://useopensource.blogspot.com/2007/08/open-source-web-conferencing.html (via shareaholic.com)

Have you ever wanted to attend a webinar but quickly discovered that the web-conference service doesn't even support your operating system? This has happened to me several times and it irks me greatly! I always make sure to tell the company that they should switch their web-conferencing service to one that supports multiple platforms including Linux.

It is somewhat hypocritical when an open source company offers a webinar about their open source product, but they don't allow customers with open source operating systems like Linux to attend. I ran into this ridiculous issue when trying to attend a Zimbra webinar. I told them that it was wrong for them to have such great multi-platform support in their product and at the same time only allow Windows users to participate in their webinars. We'll see if they take that advice to heart.

Usenix: Dartmouth Updating Diff, Grep Unix Tools

IDG News Service (12/08/11) Joab Jackson

Dartmouth University researchers are updating the grep and diff Unix command line-based text analysis tools available in all Linux and Unix distributions to handle more complex types of data.  The updates are needed because "we now tend to have more model-based configuration languages that have meaningful constructs spanning more than one line," says Dartmouth graduate student Gabriel Weaver.  The researchers say the updated tools will enable administrators to extract meaningful data from configuration files, log files, and other sources of operational data.  The output from either of these programs can be linked to other utilities, enabling them to be incorporated into scripts that automate routine system administration tasks.  The new programs, called Context-Free Grep and Hierarchical Diff, will provide the ability to parse blocks of data rather than single lines.  For each new type of data structure, a vendor would provide a pattern library identifying the basic structure of the data, which the software would then use to "extract the constructs of interest from the document," Weaver says.

Search algorithme...


Google's Search Algorithm Challenged
IDG News Service (11/19/11) Philip Willan

Padua University professor Massimo Marchiori is leading the development of Volunia, a new search engine that could challenge Google's search algorithm and lead to radically different search engines in the future. "It's not just Google plus 10 percent. It's a different perspective," says Marchiori, who contributed to the development of Google's search algorithm. "It's a new radical view of what a search engine of the future could be." Volunia's Web site allows visitors to sign up for a chance to test the beta version of the search engine, which will be launched in 12 languages by the end of the year. "If I didn't think it was something big, capable of competing with the giants of online search, I would never have got involved," Marchiori says. The project is headquartered in Padua, with funding being supplied by Sardinian entrepreneur Mariano Pireddu. "The difference of our search engine is what will enable us to emerge," Marchiori says. Pireddu says the Volunia researchers are not attempting to build a better search engine than Google's, but rather they are trying to create a different kind of search engine that can work alongside Google's.

Linux en enterprise (fr)

Constats

Les offreurs en position de force Les attentes et les exigences des clients n'influencent que peu les produits et les services disponibles; le marché de l'informatique est aujourd'hui piloté par l'offre plutôt que par la demande, qui n'est pas (encore) en position de force. (Est-ce lié à la jeunesse du marché? À l'excès d'oligopoles? À la pénurie de compétences par rapport à la demande?)

Acheter une licence n'offre aucune garantie L'acquisition d'un logiciel n'offre aucune garantie quant à sa pérennité pas plus qu'elle ne réduit l'éventuel coût de ses défauts: manques à gagner, dommages, coûts induits...

Les données otages des éditeurs d'outils Stocker des données selon un format propriétaire ou les traiter avec un programme au source non analysable revient à serrer ses informations dans un coffre dont un tiers détient la seule clé.

Un grand dessein : le partage bénéficie aux utilisateurs de logiciel La nature immatérielle du logiciel (copier ne coûte guère) rend possible de partager sans surcoût extensions et corrections, alors qu'elles améliorent la qualité du logiciel. Certains acteurs de l'open source limitent toutefois ce partage aux éléments ne profitant pas à leurs concurrents.

Aspects organisationnels et financiers

La transparence réduit les coûts La transparence requise par l'open source interdit à tout prestataire de prendre l'utilisateur en otage. Elle réduit le coût d'intégration (connexion du logiciel à l'existant), d'exploitation (résolution des inévitables embarras) ainsi que celui du ticket de sortie.

Mieux pourvoir les projets En supprimant les licences payantes l'open source ménage du budget pour la réalisation du projet, principal facteur de risque.

Atténuer le risque de l'exclusivité des compétences L'open source facilite la gestion des compétences car une entreprise utilisatrice peut librement décider de son niveau d'indépendance vis-à-vis des prestataires (développement, intégration, formation, assistance technique...).

L'accès aux données affranchit de l'acquisition de licences Tout partenaire, client ou fournisseur (par exemple le citoyen) doit pouvoir accéder aux informations sans acquitter de licence.

Mutualisation : coûts moindres et garantie qualitative Le coût acquitté par chacun pour la réalisation d'une solution immatérielle (du logiciel) utile à tous est inversement proportionnel au nombre de contributeurs au projet de la réalisation correspondante. Les profiteurs, qui se contentent de recueillir le fruit du travail des autres, peuvent être maintenus à l'écart en réservant temporairement aux seuls contributeurs certaines parties des réalisations.

Réduire le coût des matériels Les évolutions des codes open source n'exigent pas sans cesse davantage de puissance, donc n'accélèrent pas l'obsolescence des matériels.

Adéquation de l'open source

Le respect de normes assure l'interopérabilité maximale Les grandes architectures propriétaires disparaissent car les décideurs, afin de ne pas devenir des otages, évitent les outil peu conformes aux normes donc interagissant peu et mal avec d'autres. Les logiciels open source respectent les normes.

Il est souvent souhaitable voire nécessaire de maîtriser les outils Les logiciels sont imparfaits et il faut sans cesse les améliorer (maintenance corrective et adaptative), mieux vaut maîtriser ceux qui sont nécessaires au fonctionnement de l'entreprise afin de gérer l'exploitation en mode dégradé voire de les adapter. Motiver les informaticiens interdit d'employer des outils opaques (qui les transforment en presseurs de boutons). C'est souvent moins l'outil qui fait la différence que la capacité de son utilisateur à l'employer au mieux.

Améliorer la relation avec les utilisateurs créatifs Un nombre croissant d'utilisateurs développent (macros, VBA, Access ...) sans pour autant oublier leurs connaissances 'métier'. La direction chargée du système d'information peut choisir de combattre ces développements ou bien d'impliquer ces utilisateurs. Les outils open source améliorent le dialogue et l'industrialisation car établissent un périmètre technique adéquat commun.

Capitaliser sur la pratique Les constats et solutions issus du terrain doivent bénéficier au logiciel exploité (via sa version d'intégration), grâce à un processus léger mais rigoureux auquel l'open source se prête bien.

L'automatisation est un principe sain L'automatisation, bien assurée par Unix donc par l'open source, est source d'économie et de fiabilité.

Aspects techniques

L'innovation reconnue utile par le marché est issue de l'Open Source Les techniques employées par les projets contemporains sont issues de l'open source (Internet, Web...).

L'open source repose sur des techniques classiques Merise, la VABF... tout comme les «méthodes agiles» sont applicables. Les spécialistes concernés maîtrisent les techniques (famille Unix) mises en œuvre par les logiciels open source. De surcroît les concepts techniques des solutions open source évoluent en fonction de nécessités pratiques et non commerciales, donc ne connaissent pas de réforme arbitraire permettant de contraindre les utilisateurs à disposer de la plus récente version.

L'open source procède de la démarche scientifique ... et non du bricolage, car la publication est la condition de la nécessaire revue par les pairs. Un technicien devant publier ses travaux, donc les soumettre à la revue de ses pairs afin de les y associer, travaille mieux car peaufine avant de s'exposer ainsi.

Modernité du socle Unix La qualité technique de Linux et des systèmes BSD, reconnue par le marché, montre que l'adoption de la souche technique Unix découle d'une sélection menée par des experts et favorise les améliorations.

Stratégie

Réduire la dépendance Est-il préférable que son informatique dépende d'un unique fournisseur ou bien d'un ensemble de concurrents ?

Rééquilibrer l'économie du logiciel Est-il préférable : de louer, par exemple en payant des licences à une entreprise non européenne établissant librement son tarif (augmentations prévues ou non...) ? d'utiliser gratuitement un logiciel dont le coût de développement a été mutualisé, améliorable au moyen de prestations payées à des acteurs européens mis en concurrence ?

Google's Lab of Wildest Dreams

Google's Lab of Wildest Dreams
New York Times (11/14/11) Claire Cain Miller
               ; Nick Bilton

Google X is a top-secret lab where Google researchers are focusing on 100 blue-sky concepts, including reportedly the U.S. manufacture of driverless cars, space elevators that collect information or transport things into space, and fleets of robots that could aid Google with information gathering.  Other concepts the lab is concentrating on include methods for linking everyday objects to the Web in an Internet of things.  Google X reflects Google's aim to be a hub of groundbreaking research and development, and Google's Jill Hazelbaker says speculative project investment is a key component of Google's makeup.  "While the possibilities are incredibly exciting, please do keep in mind that the sums involved are very small by comparison to the investments we make in our core businesses," she says.  Google X is staffed by roboticists and electrical engineers hired from Microsoft, Carnegie Mellon University, Nokia Labs, Stanford University, New York University, and the Massachusetts Institute of Technology.  Stanford professor Sebastian Thrun, who invented the world's first driverless car, is one of the lab's research leaders, as is fellow Stanford professor Andrew Ng, who specializes in teaching robots and machines to function like people via the application of neuroscience to artificial intelligence.

NCWIT Trying to Increase Number of Women in Technology Field

Campus Technology (10/25/11) Tim Sohn

The National Center for Women & Information Technology (NCWIT) has partnered with academia and industry to improve the recruitment and retention of women in information technology (IT) and expects an additional 1,000 women to graduate with IT-related degrees next year. The program, called NCWIT Pacesetters, provides a peer group for discussing experiences, research, and results; puts on the annual NCWIT Summit on Women in IT; and offers case studies on educational reform, recruitment, and retention. Other offerings include social science research on workforce participation, education, and innovation; outreach campaigns on IT careers and education for women; and an online inventory of resources. The Pacesetters program has boosted the percentage of women computing graduates at the University of Virginia from 10 percent to 25 percent, and led to twice as many female engineer interns at Google. Meanwhile, the University of California, Santa Cruz says the program helped increase the number of female majors in computer science by 40 percent.

IBM Open-Sources 'Internet of Things' Protocol

Read Write Web (11/02/11) Scott M. Fulton III

IBM is collaborating with Eurotech to donate a complete protocol for asynchronous inter-device communication to the Eclipse Foundation. The Message Queuing Telemetry Transport (MQTT) protocol could potentially enable an Internet of things in which digitally empowered devices send messages to one another. In its final draft proposal, IBM notes that MQTT could enable a wide range of machine-to-machine messaging solutions. For example, IBM says the protocol could enable public and private transit systems "to monitor ... critical alerts, adjusting their routes and even notifying commuters and customers of alternative routes, transportation, lodging, and meals. Social networks could subscribe, allowing residents and commuters to interact, adapt, and even provide feedback and status to the city." The draft proposal also contends that current HTTP-based Web services protocols are inadequate and require adaptation in the context of machine-to-machine communication. "Open source messaging components ... will have to work equally well across the constrained networks and embedded platforms that are inherent to [the] physical world of machine-to-machine systems," the draft says. "This will enable a paradigm shift from legacy point-to-point protocols and the limitations of protocols like [simple object access protocol] or HTTP into more loosely coupled yet determinable models."

iPhone 4S : les marchés chahutent l'action Apple


iPhone 4S : les marchés  chahutent  l'action Apple Business - Sur un marché très instable, l'action Apple a été malmenée après l'annonce du nouvel iPhone 4S en perdant jusqu'à 5 % en cours de séance pour finir en retrait de 0,56 %.
 Tim Cook  a vécu son baptême du feu. Il se souviendra longtemps de son premier keynote en qualité de CEO d'Apple. D'abord parce que remplacer Steve Jobs est un challenge difficile à relever. Ensuite parce que l'action Apple a été fortement secoué après ses annonces perdant jusqu'à 5 % en cours de séance.
Très attendue, la version 5 de l'iPhone n'a finalement pas été annoncée. C'est la version 4S, hypothèse largement défendue par ailleurs, qui a été dévoilée avec son processeur double cœur A5, son système de reconnaissance vocale et son capteur 8 megapixels.
Est-ce la raison de la nervosité du marché ? "Cela fait 16 mois et tout ce qu'on a, c'est un processeur A5 dans l'iPhone 4 existant", commente Colin Gillis, analyste chez BGC Partners cité par Reuters.
Sous la menace de Samsung 
Les analystes craignent que cette évolution du dernier né de la gamme iPhone soit jugée insuffisante par les utilisateurs pour les pousser à acheter ce nouveau modèle. Et donc de réduire le volume de ventes du smartphone, qui représente 40 % du chiffre d'affaires, pour le dernier trimestre de l'année.Lors du troisième trimestre, clos en juin, Apple avait écoulé 20 millions de terminaux.
Car s'il est leader du marché des smartphones avec 18,4% de parts de marché, selon IHS iSuppli, Apple vit  néanmoins sous la menace de Samsung (17,8%) dont la gamme Galaxy se vend très bien.
La bataille se livre aussi sur les systèmes d'exploitation. En annonçant iOS5, Apple veut rattraper son retard sur Android qui le domine largement sur le marché américain, selon Nielsen, avec 43 % de parts de marché contre 28%.  Le marché français est à cet égard un bon exemple de ce que redoutent les analystes avec un duo Samsung/Android quimène la danse.
Au terme de ce keynote, Apple dispose d'une gamme d'iPhone mise à jour : le 3GSs'installe dans l'entrée de gamme, l'iPhone 4 dans le milieu et le 4 S  dans le haut de gamme.

NASA Unbolts Open Source Space Applications Challenge

Network World (09/20/11) Michael Cooney

The National Aeronautics and Space Administration (NASA) recently announced an open source-based application competition with the goal of delivering a new generation of software that can address space, weather, and economic issues. NASA will collaborate with other interested space agencies worldwide on an International Space Apps Challenge that will encourage researchers to create, build, and invent new applications that can address world-class issues. "The International Space Apps Challenge is an innovative international collaboration that accelerates the development of solutions focused on making government better and addressing critical issues on our planet, such as (but not limited to) weather impacts on the global economy and depletion of ocean resources," according to NASA. The agency wants a collaborative platform to share early-stage government technology-based innovations, which can receive feedback from citizens and commercial stakeholders. In addition, NASA wants a tool to leverage distributed crowdsourcing analysis by citizens to help process, archive, distribute, and visualize data for space exploration.

Application Development Boosts IT Job Market: Dice Report

eWeek (09/07/11) Nathan Eddy

The number of available technology jobs as of Sept. 1 stood at 82,836, with 50,659 full-time positions, 35,378 contract positions, and 1,565 part-time positions, reports Dice.com. Dice's Alice Hill notes that one of the fastest growing areas of hiring requests involves mobile application development. She says that just 17 percent of technology professionals have published a mobile app, and of this group only 27 percent work on mobile initiatives full time. Although full-time developers prefer to work with the iPhone, more employers are searching for Android developers, according to Hill. In addition, she says tech professionals involved in iPhone development report nine times more income from apps, but Android income should rise along with the growth in app advertising revenue. "For tech talent, taking on a mobile app project is a great way to broaden skills in an area that is primed for more growth," Hill says.

Parallel Programming Skills Crisis Could Stall Server Evolution

Computerworld Australia (09/12/11) Sandra Van Dijk

The lack of parallel programming expertise worldwide will become a major issue for the information technology (IT) industry over the next 10 years, warns a RMIT University report. Advanced parallel programming skills are hard to find among professional programmers because it is taught only as an advanced elective in most computer science curricula, says RMIT professor James Harland. The report warns that without a massive injection in parallel programming talent in the IT sector, new server platforms will stall, especially in areas such as fabric-based computing. The lack of programming skill can lead to frozen states commonly known as a deadly embrace, but techniques to deal with frozen states are only taught briefly in computer science and IT programs, according to Harland. "Hence, the only real way to overcome such obstacles is to spend more time on parallel programming techniques in these courses," he notes. Parallel programming represents a different paradigm of software development in that it introduces the notion of complexity into software development, similar to learning a new programming language, says RMIT's John Lenarcic. "Only a minority of developers have sufficient training to handle parallel programs, and only a fraction have enough experience to do it well," says Gartner analyst Carl Claunch.

Special Report Highlights 'Greatest Hits' of Scientific Supercomputing

Oak Ridge National Laboratory (09/02/11) Dawn Levy

The Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, which is jointly managed by the Argonne National Laboratory and the Oak Ridge National Laboratory, is developing INCITE in Review, a special report that will highlight the 22 greatest hits of science and engineering accomplishments made by researchers running complex simulations on the U.S. Department of Energy's supercomputers. "Whether it's gaining a better understanding of the universe or engineering solutions for a growing, energy-hungry populace, the investigations enabled by INCITE are making the world a smarter, more sustainable place," says National Center for Computational Science director James J. Hack, who co-wrote the report's introduction. "We are proud to tell the story of INCITE's role to date in advancing the frontiers of human knowledge for the benefit of all." INCITE projects are designed to accelerate breakthroughs in fields in which major advancements would be impossible without supercomputing. Since INCITE was created, researchers have been allotted more than 4.5 billion supercomputer processor hours, with 1.7 billion in just the 2011 calendar year.

As Tech Evolves, Will PCs Be Left Behind?

USA Today (09/06/11) Jon Swartz

The rapid shift from personal computers (PCs) to mobile devices and cloud-based computing has restructured the high-tech industry. Technology has exhausted the limits of the PC as a platform and the future will center on mobile devices, predicts Google chairman Eric Schmidt. "The PC device has evolved in terms of size, shape, use, and ubiquity," says former IBM executive Pat Richards. The younger generation, especially, is abandoning desktop computers and laptops for smartphones and iPads. The switch to mobile devices is apparent in the latest sales trends, as sales of smartphones will rise 56 percent to 467.7 million this year, according to Gartner, while tablet sales will grow nearly four times to 69.8 million this year. However, some experts believe the PC is not dying and instead is simply changing its size and shape, as handheld devices become the new must-have consumer product. In the future, consumers will get information from whatever device best suits the data, says VMWare CEO Paul Maritz. He says a person's data "will determine what devices look like, rather than the other way around, because it will outlive any particular piece of hardware where it may reside."

Hacking Targets Multiply

Wall Street Journal (09/09/11) Jennifer Valentino-DeVries 

U.S. government officials and security researchers warn that cyberattacks are a growing threat for all types of devices as they become linked to the Internet or cell phone networks. "They aren't just in automotive systems but in security systems, industrial control systems, medical devices," says iSec Partners' Don Bailey. He and iSec colleague Mathew Solnik recently demonstrated that they could unlock and start a car by sending text messages to the vehicle's alarm system, and the implication is that this same method could be used to interfere with businesses or critical services. The researchers point out that devices connected to a cellular network have several vulnerabilities, including chips that may not be able to manage complex security measures, and an inability to authenticate the network they receive messages from. The U.S. Department of Homeland Security (DHS) is working with technology manufacturers and users to understand the dangers, and a DHS official notes that protecting the devices is especially challenging because they cannot easily be patched on a routine basis. Bailey says that better microcontrollers could mitigate some hacking threats, while devices also should be required to authenticate the sources of messages and their networks.

Flash Memory That'll Keep on Shrinking

Technology Review (09/02/11) Katherine Bourzac

Researchers at the University of California, Los Angeles (UCLA) and Samsung have developed a type of flash memory that uses graphene and silicon to store information. The researchers say that the use of graphene could extend flash's viability far into the future and could lead to portable electronics that can store much more data than today's devices. "We're using graphene to help extend the capabilities of the conventional technology," says IBM Watson Research Center researcher Augustin Hong, who worked on the technology while at UCLA. The graphene flash memory prototypes use less power than conventional flash memory and they can store data more stably over time, even when miniaturized, according to the researchers. Graphene-based flash memory cells perform better due to the material's chemical structure and electrical properties, says UCLA professor Kang Wang, who led the research. Graphene also can hold much more charge than silicon without leaking, which is a common problem with conventional flash systems as the devices get smaller. Although the graphene-based devices have not been reduced to the size of some silicon-based devices, there are no known properties of graphene that would cause the performance to falter as the devices get smaller.

Mobile Phone Data in Haiti Improves Emergency Aid

Karolinska Insitutet (08/31/11) Katarina Sternudd

Researchers at the Karolinska Institutet and Columbia University developed a program to monitor the daily movements of 2 million mobile phone users in Haiti to track cholera outbreaks. "We rapidly received mobile phone data and within 12 hours we were able to send out analyses describing which areas had received people from the cholera outbreak zone in order to provide information on areas at potentially increased risk of new outbreaks," says Karolinska's Linus Bengtsson. The researchers launched the project after the devastating earthquake in January 2010, and estimated that more than 600,000 people left Port-au-Prince within 19 days of the disaster. Although the researchers have shown that the movements of the mobile phones match those of a United Nations-led study conducted during a stable phase six months after the earthquake, their analysis differed from estimated migration patterns that were used during the initial phase of relief response. "We believe that the method can bring about important improvements in humanitarian relief and development cooperation," Bengtsson says.
