Workers and residents exposed to asbestos in Australia - World Socialist Web Site

Workers and residents exposed to asbestos in Australia
By James Cogan
5 June 2013

Another scandalous example of government and corporate contempt for working class lives and health has come to light. On at least 20 occasions this year, workers employed in the roll-out of optic fibre cabling for the National Broadband Network (NBN) have “mishandled” material containing asbestos. In one documented incident, in Sydney’s western suburb of Penrith, asbestos was scattered in a residential area, exposing the workers and other people to the potentially cancer-causing consequences of inhaling it.

Genève, Ville Vivante, représentation époustouflante des communications

http://villevivante.ch

The mobile phone has rapidly become a very essential tool, that we carry with us all the time, everywhere we go. It has become the focus of our communication and information in a hyper-connected world, which tolerates less and less that we disconnect or just don’t have immediate access to information.

Based on this conclusion the City of Geneva decided to take the challenge to visualize these digital traces created by our mobile phones. The objective of this installation is to make this data visible and allow you to explore these streams of connected people around the city, in their everyday life.

UK Farmers Want Faster Internet, Build Their Own | Singularity Hub

They opted to build an ultrafast fiberoptic network themselves.

Located in rural Lanchashire in the northern part of England, the local landowners began working together to spur interest in bringing fast Internet to their rural community. As reported by the BBC, they hammered out a business plan as a “not for profit” community benefit society and began selling shares into Broadband for the Rural North (B4RN). To get the network built, locals invested their time and physical labor to dig trenches and lay fiber cables while raising half a million pounds. After installing the network on the property, which is estimated to be around $1,500 (much less than what ISPs would charge), the cost of the service to residents is only $45 a month and delivers Internet speeds that are about 75 times faster than the average in the UK.

Why a one-room West Virginia library runs a $20,000 Cisco router
http://arstechnica.com/tech-policy/2013/02/why-a-one-room-west-virginia-library-runs-a-20000-cisco-router

Marmet, West Virginia is a town of 1,500 people living in a thin ribbon along the banks of the Kanawha River just below Charleston. The town’s public library is only open Thursdays, Fridays, and Saturdays. It’s housed in a small building the size of a trailer, which the state of West Virginia describes as an “extremely small facility with only one Internet connection.” Which is why it’s such a surprise to learn the Marmet Public Library runs this connection through a $15,000 to $20,000 Cisco 3945 router intended for “mid-size to large deployments,” according to Cisco.

Information technology in Africa: The next frontier | The Economist

This month Microsoft, which has offices in 14 African countries, unveiled a smartphone to be sold in several African markets. It is made by China’s Huawei and uses Microsoft’s new operating system.

In Kenya Microsoft intends to bring broadband to places that do not yet have electricity, using solar power and “white spaces”, or spare broadcast-television frequencies. Within a year, says Fernando de Sousa, the general manager for Microsoft in Africa, 6,000 people in the Rift Valley will have access to broadband. Similar projects are planned elsewhere. Since October Microsoft has been running “app factories” for programmers in Egypt and South Africa.

(...) Kenya may be keenest. In 2006, frustrated by the slow progress of a regional plan to lay a fibre-optic cable along the east coast of the continent, Kenya negotiated its own link to the United Arab Emirates. The Gulf cable landed in 2009.

In many sectors, such as health care, education and water, as well as traffic, governments are sure to be important customers for IT companies. But private clients matter too, especially in telecoms and finance. The mobile phone, the first computer many Africans will own (see chart 2), is the bridge between the two.

To Westerners, “mobile banking” is a new way of doing something old. To many Africans, it is the obvious way of doing something new. In Kenya M-PESA, a system of transferring money over phones, is an everyday, reliable utility. Equity Bank, a fast-growing bank, most of whose customers have never had an account before, has come of age with mobile technology:

Waste Is Seen in Program to Give Internet Access to Rural U.S. - NYTimes.com

Aux #États-unis, on tire des #câbles n’importe comment dans certaines zones rurales

Rural areas certainly suffer a lack of high-speed Internet access. While about 88 percent of urban households in the United States have access to high-speed #cable Internet service, only 40 percent of rural households do, according to the Federal Communications Commission and the Commerce Department.

About 20 percent of United States households have access to #fiber optic Internet service, the fastest connection, compared with 86 percent in Japan and two-thirds in South Korea. But the Eagle-Net experience in Colorado demonstrates that in the haste to get broadband everywhere, some grant planners appeared not to have taken into account the current condition of #infrastructure.

Le principal motif de satisfaction des collectivités locales viendra sans doute du long chapitre consacré à la « question centrale et stratégique pour la soutenabilité financière des projets de déploiements de réseaux #FTTH (#fibre jusqu’à l’abonné) notamment publics » que constitue le sort du réseau #cuivre de boucle locale historique, celui de France Télécom, le bon vieux réseau téléphonique qui sert actuellement de support à l’ADSL. Car le projet de feuille de route dit explicitement qu’« il n’est pas économiquement pertinent de maintenir durablement deux réseaux parallèles », le cuivre et la fibre, et qu’il faudra examiner avec l’opérateur historique « les conditions opérationnelles, juridiques et financières de telles opérations d’extinction du cuivre », laquelle se fera « de manière progressive et organisée. »

Digital revolution lights up Africa with maps, mobiles, money and markets | World news | guardian.co.uk
http://www.guardian.co.uk/world/2012/oct/30/africa-digital-revolution-mobile-phones

Thirty years later, maps of the city in the Democratic Republic of the Congo are still in short supply. So Diakubama decided to create the first one of his home city. He spent hours at his computer in Brussels, where he now lives, using Google Map Maker software and entering the streets he could recall. He hired an assistant to tour Mbandaka by bike and name the streets on a map scanned in pdf format and printed out.

Diakubama’s efforts have been replicated across Africa by scores of amateur mapmakers who have collectively pinpointed hundreds of thousands of roads, cities and buildings in remote areas ignored by colonial cartographers. This is just one example of how the digital revolution has not only caught up in Africa, but is in some respects moving faster and differently from the west.

“New technologies are in the process of transforming the lives of people,” Diakubama said. "Mobile telephony has equipped our lives by allowing communication between cities and villages without having to move; to announce a death in the family, for example.

Glasnost: Test if your ISP is shaping your traffic
http://broadband.mpi-sws.org/transparency/glasnost.php

The goal of the Glasnost project is to make ISPs’ traffic shaping policies transparent to their customers. To this end, we designed Glasnost tests that enable you to check whether traffic from your applications is being rate-limited (i.e., throttled) or blocked.

Glasnost tests work by measuring and comparing the performance of different application flows between your host and our measurement servers. The tests can detect traffic shaping in both upstream and downstream directions separately. The tests can also detect whether application flows are shaped based on their port numbers or their packets’ payload. For more details on how Glasnost tests work, please read our NSDI 2010 paper.

We configured our tests to be conservative when declaring the presence of shaping, i.e., passing our tests does not necessarily mean that there is no throttling occurring on your link.

Les résultats des tests sont analysés ici :

Héberger des vidéos sur son propre serveur... sans le tuer
http://sebsauvage.net/rhaa/index.php?2012/10/03/12/07/39-heberger-des-videos-sur-son-propre-serveur-sans-le-tuer

Héberger soi-même des vidéos pose des problèmes épineux :
– cela consomme votre bande passante vitesse grand V ;
– certains hébergeurs vous factureront chèrement les dépassements, d’autres couperont tout simplement votre site.

Si votre vidéo devient populaire, vous aurez des problèmes de débit (votre hébergeur peinant à servir la vidéo à tout le monde). Vous n’avez pas les CDN de YouTube pour répartir la vidéo sur différents serveurs dans le monde. Et vous n’avez probablement pas les moyens de vous payer des CDN Akamai.

Enfin il faut que vous gériez vous-même la compatibilité entre navigateurs : utilisation du tag video d’HTML5 ou non, codecs vidéo supportés... avouez, c’est chiant.

J’ai fini par trouver une solution très simple et qui ne tue pas votre serveur.

Association of American Geographers Annual Meeting
9-13 April 2013
Los Angeles

the particular asymmetries in the representation and production of spatial information on the geoweb remain opaque and often hidden. This session will focus on the geographies, networks, and power relations of the digital inequalities of the geoweb. We hope to attract research at a range of scales (from the household to the national level) and contexts. Possible topics could include:

– Gatekeepers of digital information
– Demographic or geospatial inequalities
– Invisible exploitation of virtual labor
– Quantitative studies of geoweb representation
– Qualitative studies and virtual ethnographies
– Studies of normative assumptions built into geoweb tools and platforms
– Studies of racialized, gendered, or otherwise exclusionary geoweb spaces
– Differences in internet accessibility (i.e. mappings of broadband or wireless penetration)

De plus en plus de données passent sur l’Internet donc le travail sur l’optimisation des protocoles, pour que les octets passent plus vite, continue. Quelques articles récents sur le protocole #TCP :

« TCP sucks » de Bram Cohen (celui de BitTorrent) http://bramcohen.com/2012/05/07/tcp-sucks La tonalité « règlement de comptes » est désagréable mais, techniquement, c’est bien argumenté. Il faut lire les commentaires qui, à part quelques trolls arrogants (comme celui qui parle des « comical limitations » de TCP), sont bien écrits (et mettent sérieusement en cause la vision de l’auteur). Bien se rappeler que Cohen est du côté des applications, il n’écrit pas de programmes pour les routeurs (pour lesquels l’approche dite #RED est actuellement proposée) ou pour le noyau du système d’exploitation, donc il voit tous les problèmes comme relevant des applications. Sa solution est là : http://en.wikipedia.org/wiki/Micro_Transport_Protocol

À noter que le problème de #BitTorrent n’est pas uniquement d’aller vite mais aussi de céder rapidement devant des transferts plus importants, d’où les allusions de Cohen au projet #LEDBAT ►http://www.bortzmeyer.org/6297.html

Cohen fait souvent allusion au « bufferbloat ». Pour s’instruire sur ce concept, voir http://en.wikipedia.org/wiki/Bufferbloat et http://queue.acm.org/detail.cfm?id=2076798 Pour s’instruire sur le RED http://en.wikipedia.org/wiki/Random_early_detection

The film industry made $84 billion in 2010. Thanks to 3D, Blu-ray, and broadband streaming to  electronic devices, the firm projects that the movie industry will grow 6.1% annually to $113 billion in 2015. In that same window of time, video games, which made $56 billion in 2010, are expected to see 8.2% annual growth to $82 billion. This means that the video game industry is growing at a faster rate and will eventually catch up to film
