BitTorrent

BitTorrent
Programmer Bram Cohen, a former University at Buffalo graduate student in Computer Science,[4] designed the protocol in April 2001 and released the first available version on July 2, 2001,[5] and the final version in 2008.[6] BitTorrent clients are available for a variety of computing platforms and operating systems including an official client released by Bittorrent, Inc. As of 2009, BitTorrent reportedly had about the same number of active users online as viewers of YouTube and Facebook combined.[7][8] As of January 2012[update], BitTorrent is utilized by 150 million active users (according to BitTorrent, Inc.). Based on this figure, the total number of monthly BitTorrent users can be estimated at more than a quarter of a billion.[9] Description[edit] The middle computer is acting as a seed to provide a file to the other computers which act as peers. The file being distributed is divided into segments called pieces. When a peer completely downloads a file, it becomes an additional seed.

BitTorrent Based DNS To Counter US Domain Seizures The domain seizures by the United States authorities in recent days and upcoming legislation that could make similar takeovers even easier in the future, have inspired a group of enthusiasts to come up with a new, decentralized and BitTorrent-powered DNS system. This system will exchange DNS information through peer-to-peer transfers and will work with a new .p2p domain extension. In a direct response to the domain seizures by US authorities during the last few days, a group of established enthusiasts have started working on a DNS system that can’t be touched by any governmental institution. Ironically, considering the seizure of the Torrent-Finder meta-search engine domain, the new DNS system will be partly powered by BitTorrent. In recent months, global anti-piracy efforts have increasingly focused on seizing domains of allegedly infringing sites. The Dot-P2P project was literally started a few days ago, but already the developers are making great progress.

Chmura obliczeniowa Diagram przedstawiający „chmurę” Zasada działania chmury obliczeniowej[edytuj | edytuj kod] Zasada działania polega na przeniesieniu całego ciężaru świadczenia usług IT (danych, oprogramowania lub mocy obliczeniowej) na serwer i umożliwienie stałego dostępu poprzez komputery klienckie. Dzięki temu ich bezpieczeństwo nie zależy od tego, co stanie się z komputerem klienckim, a szybkość procesów wynika z mocy obliczeniowej serwera. Wystarczy zalogować się z jakiegokolwiek komputera z dostępem do Internetu by zacząć korzystać z dobrodziejstw chmury obliczeniowej. Pojęcie chmury nie jest jednoznaczne, w szerokim znaczeniu przetwarzanym w chmurze jest wszystko przetwarzane na zewnątrz zapory sieciowej, włączając w to konwencjonalny outsourcing[2]. Rodzaje chmur[edytuj | edytuj kod] Rozróżniamy chmury: Modele chmury obliczeniowej[edytuj | edytuj kod] Współcześnie coraz więcej nowych funkcjonalności umieszczanych jest w modelu chmur obliczeniowych.

Truly Decentralized BitTorrent Downloading Has Finally Arrived BitTorrent is branded as a peer-to-peer technology, but despite this label the downloading process still relies heavily on central servers. In the first place there are the BitTorrent search engines and indexes such as The Pirate Bay and isoHunt. These are needed to search for content and to grab the .torrent file one needs to download a file. Besides these torrent sites, most BitTorrent downloads are still managed by so-called trackers. Finally central servers are used by moderators to help hunt spam and malware. In the last years these ‘central server’ vulnerabilities have caused a number of minor inconveniences for torrent users. To address these issues, ideally BitTorrent downloads should no longer require a central server. The latest version of the Tribler BitTorrent client (Win, Mac and Linux), released only a few minutes ago, is capable of all the above and many more things that could be described as quite revolutionary. Triber: search, download and play (large). Tribler Channels

Computación en la nube Computación en la nube, o «la nube» La computación en la nube (del inglés cloud computing),[1]​ conocida también como servicios en la nube, informática en la nube, nube de cómputo o simplemente «la nube», es un paradigma que permite ofrecer servicios de computación a través de una red, que usualmente es internet. Introducción[editar] La computación en la nube es la disponibilidad a pedido de los recursos del sistema informático, especialmente el almacenamiento de datos y la capacidad de cómputo, sin una gestión activa directa por parte del usuario. A menudo, el término «computación en la nube» se lo relaciona con una reducción de costos, disminución de vulnerabilidades y garantía de disponibilidad. La computación en la nube es un nuevo modelo de prestación de servicios tecnológicos que impacta sin lugar a dudas en diversos negocios. Comienzos[editar] Fundamentos[editar] Desde los años sesenta, la computación en nube se ha desarrollado a lo largo de una serie de líneas. Tipos de PaaS[editar]

OneSwarm: The Privacy Aware BitTorrent Client Developed at the University of Washington, OneSwarm is a BitTorrent client that allows users to share files "anonymously" or with a specific group of friends. These features give users more control over their privacy, while maintaining a decent download speed. The client operates from within an Internet browser and is available for Mac, Windows and Linux. Those who’ve been reading TorrentFreak for long enough may remember how the MPAA and RIAA accused a printer at the University of Washington of copyright infringement a few years ago. With their research, the researchers pointed out that gathering evidence on BitTorrent downloaders is full of pitfalls. Perhaps not coincidentally the same research group is also behind the “privacy preserving” BitTorrent client OneSwarm, currently developed by Tomas Isdal and Michael Piatek, two PhD students at the University of Washington. Unlike other regular BitTorrent clients, OneSwarm allows users to share files only with a selected group of friends.

Modelos de Despliegue de CloudComputing (taxonomía del NIST) » Realcloud Project En el comentario del 20-feb-2011 veíamos la definición que el NIST realiza para el concepto de CloudComputing, y al día siguiente (el 21-feb-2011) analizábamos los 3 “Modelos (o niveles) de Servicio” (SaaS, Paas, e IaaS) tal como los define el NIST (pues ambas, definición y clasificación, son la más aceptadas en la actualidad). También el NIST distingue entre 4 “Modelos de Despliegue” (Privado, Comunitario, Público e Híbrido) que introduce una ligera diferencia (el modelo comunitario) sobre el resto de la bibliografía actual al respecto (y que, en mi opinión, es importante considerar en un país como España, donde el cooperativismo tiene buenas raíces): Nube Pública: La infraestructura de la nube está disponible al público en general (o un subconjunto en función de los criterios de venta del Proveedor). La infraestructura pertenece a la organización que vende sus servicios de Cloud Computing.

Researchers Improve BitTorrent Download Speeds Researchers from the Tribler project at Delft University of Technology are proposing a new set of rules that should significantly improve the download speeds of many BitTorrent users. The new "Superior Seeding Standard" implemented in the latest release of the Tribler BitTorrent client is inspired by the ratio-enforcement policies at private tracker communities, but doesn't discriminate against people with low bandwidth connections. Some scientists devote their lives to finding a cure for terminal illnesses, others hope to discover new planets in galaxies far away, but there’s also a group of scientists mostly concerned with improving BitTorrent. The Tribler team at Delft University of Technology are such a group, and they have found a way to improve download speeds for BitTorrent users who are committed to sharing. Tribler’s BitTorrent client has been in development for more than 5 years and continues to deliver experimental improvements and innovative ideas. The Paper

BitTorrent Pirates Go Nuts After TV Release Groups Dump Xvid Some Internet piracy groups decided to implement some new regulations and standards last week. Instead of releasing TV shows in the Xvid/avi format, groups responsible for putting major TV shows online switched to MP4/x264. Outraged by the lack of democracy, some BitTorrent users are directing their anger at bewildered torrent sites and even threatening to boycott releases. Every now and again, the world’s most famous piracy release groups get together and have a big old meeting to decide how they’ll carry out their future activities. Ok, so the last sentence isn’t true, but nevertheless that appears to be the current assessment of events according to some BitTorrent users. The problem stems back to a new document which details a set of standards TV show release groups such as LOL and MOMENTUM will have to live up to in order to comply with so-called ‘Scene rules’. “x264 has become the most advanced video codec over the past few years. “LOL, why are all your new uploads MP4 format?

New Data Exposes BitTorrent Throttling ISPs New data published by the Google-backed Measurement Lab gives a unique insight into the BitTorrent throttling practices of ISPs all over the world. In the U.S. and Australia most large ISPs limit less than 10 percent of BitTorrent transfers. In the UK and Canada on the other hand, some providers interfere with up to three-quarters of all BitTorrent traffic. New data collected by Measurement Lab (M-Lab) shows how frequently Internet providers limit torrent traffic. Previously the researchers published data up until 2010, and now the results have been updated to include the first quarter of 2012. United States BitTorrent throttling in the US is not as prevalent as it used to be. As a result of this ruling, the throttling percentage took a dive from nearly 50 percent to only 3 percent in 2010. Throttling was also greatly reduced at Charter over the last year, from 11 percent down to 4 percent. Worst: Cox (6%) Best: Comcast, Verizon, AT&T and others (3%) Worst: BT (65%) Best: O2 (2%) Canada

Certified BitTorrent Box Brings uTorrent to Your TV The first ever certified BitTorrent Android box goes on sale today, allowing users to stream files downloaded with uTorrent wirelessly to their television. The new set-top box supports playback of all popular video formats and can also download torrents by itself, fully anonymously if needed. With a quarter billion active users a month BitTorrent is without a doubt the most used file-sharing platform. The vast majority of these BitTorrent users download video files, but despite these staggering statistics it can still be quite cumbersome to play downloaded files on the old-fashioned TV. The first ever certified Android-powered BitTorrent box aims to change this. After the initial December launch was delayed, the BBK BitTorrent box officially goes up for sale today. While we have seen devices that support BitTorrent downloads before, this is the first one that can can also stream content downloaded through uTorrent and BitTorrent clients on the local network.
