Hasta donde vamos a llegarPROTESTA PUBLICA POR INOPERANCIA JUDICIAL
El pasado 21 de Febrero del 2007 ocurrió un hecho abominable en el municipio de Mella, Provincia Independencia, en el que una menor de 12 años fue brutalmente violada en reiteradas ocasiones por unos sujetos que han sido identificados como Juan Carlos Cuevas, Ernesto Pérez (Meneo), Juan de la Rosa Urbàez, Manuel E. Marmolejos, Tirson Vásquez Mancebo, alias Chita o Patricio y otros identificados tan solo con los motes de los mudos Guandul, Chinito y el hijo de Villita. Celulares de pulseraDe Infobae.com,
Los celulares de pulsera, la novedad tecnológica
Se basan en la nanotecnología, que permite que el equipo se limpie a sí mismo además de captar datos del entorno como la temperatura o la contaminación ambiental. Conozca más detalles del Morph
Este modelo fue presentado por Nokia junto a la Universidad de Cambridge. Fue generado con tecnologías microscópicas agrupadas en lo que se conoce como nanotecnología.
El Morph es el primer celular flexible, capaz de adaptarse a la muñeca del usuario y ser transportado como una pulsera o un reloj. Está diseñado con un material transparente y utiliza baterías de bajo consumo y mayor duración. Según explican desde la empresa, esta nueva tecnología microscópica "puede hacer que los equipos tengan una superficie que se limpie a sí misma". Además, permite incluirles nanosensores, capaces de interrelacionarse con el entorno para proveer al usuario de información importante, como cambios de temperatura en el ambiente o niveles de contaminación. El equipo fue presentado junto con la exposición “Diseño y la Mente Elástica” que el Museo de Arte Moderno de Nueva York (MoMA) ofrecerá desde el 24 de febrero hasta el 12 de mayo del 2008. Morph es un concepto que demuestra cómo los dispositivos móviles del futuro podrán ser flexibles y estirables, permitiendo al usuario transformarlos en formas radicalmente diferentes. Vista SP1 will break some appsFrom CNET News,
Microsoft has published a list of programs that will not work or that will suffer from reduced functionality after the installation of Vista Service Pack 1. The list of programs consists mostly of security applications, such as Trend Micro Internet Security 2008. However, programs such as The New York Times Reader application also feature on the list. Users are advised to install updates from the application vendor to fix the problem. "Windows Vista Service Pack 1 contains many security, reliability, and feature updates for Windows Vista," the company said. "A program may experience a loss of functionality after you install Windows Vista SP1. However, most programs will continue to work as expected after you install Windows Vista SP1." The list is not considered to be comprehensive, and Microsoft has asked users who encounter problems with other applications to first restart their PC and, if they still encounter problems, to install a newer version of the program or contact the software vendor. Without SP1 incompatibilities, Windows Vista is already facing an ingrained perception by enterprise users of incompatibility with old systems, said Joseph Sweeney, an analyst at Intelligent Business Research Services. February 28 Cronicanto pendejo a una patria en bandoleraDel Periodico El Nacional,
Pablo McKinney Cronicanto pendejo a una patria en bandolera Por no tener puesto el cinturón de seguridad, un agente de la AMET impone una multa a una trigueña altiva que maneja una Toyota Rav4, mientras a su alrededor, centenares de choferes de concho y voladoras, sin revista ni listín, algunos armados ilegalmente, circulan sin el mismo cinturón de la damisela en flor contravenida. A la hora de cobrar un préstamo, los bancos son implacables, severos como un guardia trujillista o un abogado viejo. Es su tarea. Sin embargo, el símbolo mayor de padrefamilismo militante, la Fenatrano, desde el año 2002 adeuda 173 millones de dólares, (unos 6,800 millones de pesos) al banco del Estado y no hay manera de que les sean cobrados como se le cobra al resto de los mortales. Como me dijo el Kates en El Bomba, en una noche de chercha y discusión cervecera; "ellos son los "padres de familia", Maquinini, nosotros apenas somos los "hijos de la gran p?". En el comercial de televisión de la CDEE que realiza Freddy Beras Goico, se admite que los ciudadanos que trabajan le pagan la energía eléctrica a los que no lo hacen. Tenemos un Estado implacable en sus cobranzas y sus leyes cuando se trata del Club de los Pendejos, (constituido por ciudadanos laboriosos que no queman gomas ni damas embarazadas, que no andan con chilenas atacando a otros ciudadanos), mientras manda a dormir por un siglo la justicia y el respeto cuando a de los amos del terror y el chantaje se trata, "y así no podemos, profesor, no podemos." La mayor parte de la clase media de hoy, fuente originaria del club, lo es porque desde siempre ha tenido tres trabajos y los pies en la tierra. No todos somos lavadores de activos ni ladrones del erario, señores míos. Aquí, para que anduviera como anda hoy el sistema financiero: Más organizado que el escritorio de un peledeísta de los años ochenta, más correcto que un evangélico en sábado, tuvimos que padecer 40 años de impunes fraudes financieros de todo tipo, color, gobiernos, apellidos. De igual manera, quizás sea necesaria una vaina, un caos enamorado, un rayo que no cesa, otro abril en bandolera, para que los dominicanos de bien, de una vez y por todas reaccionemos, en fin, que se trata de la madre tierra, "padre, deje ya de llorar, que nos han declara'o la guerra." Por el 27 F de ayer, queda aquí la advertencia. Disturbing pictures from Abu Ghraib - WARNING Explicit MaterialBy Wired.com,
NSFW: VIEWER DISCRETION IS ADVISED. As an expert witness in the defense of an Abu Ghraib guard who was court-martialed, psychologist Philip Zimbardo had access to many of the images of abuse that were taken by the guards themselves. For a presentation at the TED conference in Monterey, California, Zimbardo assembled some of these pictures into a short video. Wired.com obtained the video from Zimbardo's talk, and is publishing some of the stills from that video here. Many of the images are explicit and gruesome, depicting nudity, degradation, simulated sex acts and guards posing with decaying corpses. Viewer discretion is advised.
Information EpidemicsNice - Microsoft to use friendly worms to spread software patches. From NewScientist,
Microsoft researchers are hoping to use "information epidemics" to distribute software patches more efficiently. Milan Vojnović and colleagues from Microsoft Research in Cambridge, UK, want to make useful pieces of information such as software updates behave more like computer worms: spreading between computers instead of being downloaded from central servers. The research may also help defend against malicious types of worm, the researchers say. Software worms spread by self-replicating. After infecting one computer they probe others to find new hosts. Most existing worms randomly probe computers when looking for new hosts to infect, but that is inefficient, says Vojnović, because they waste time exploring groups or "subnets" of computers that contain few uninfected hosts. Smart strategiesVojnović's team have designed smarter strategies that can exploit the way some subnets provide richer pickings than others. The ideal approach uses prior knowledge of the way uninfected computers are spread across different subnets. A worm with that information can focus its attention on the most fruitful subnets – infecting a given proportion of a network using the smallest possible number of probes. But although prior knowledge could be available in some cases – a company distributing a patch after a previous worm attack, for example – usually such perfect information will not be available. So the researchers have also developed strategies that mean the worms can learn from experience. In the best of these, a worm starts by randomly contacting potential new hosts. After finding one, it uses a more targeted approach, contacting only other computers in the same subnet. If the worm finds plenty of uninfected hosts there, it keeps spreading in that subnet, but if not, it changes tacktic. February 25 Keeping tabs on the Hacker UndergroundFrom SearchSecurity.com,
Computer attackers are constantly innovating, improving their attack technology and business schemes. A key resource bad guys often rely on is the exploit techniques pioneered and shared by security researchers and people in the computer underground; a mixture of white hat and gray hat security pros.
Vulnerability disclosure is a controversial topic with no shortage of opinions, but regardless of your personal stance, the reality is malicious hackers will use whatever information is available to them. That means security professionals should keep abreast of the latest exploits and attack techniques by carefully monitoring certain Web sites of researchers and the computer underground. Monitoring what they are working on today can help anticipate the techniques attackers will likely use tomorrow. To that end, let's look at some of the most valuable Web sites for understanding late-breaking attack techniques.
Researchers: Disk Encryption not secureFrom Wired Blog network,
Researchers with Princeton University and the Electronic Frontier Foundation have found a flaw that renders disk encryption systems useless if an intruder has physical access to your computer -- say in the case of a stolen laptop or when a computer is left unattended on a desktop in sleep mode or while displaying a password prompt screen. The attack takes only a few minutes to conduct and uses the disk encryption key that's stored in the computer's RAM. The attack works because content as well as encryption keys stored in RAM linger in the system, even after the machine is powered off, enabling an attacker to use the key to collect any content still in RAM after reapplying power to the machine. "We've broken disk encryption products in exactly the case when they seem to be most important these days: laptops that contain sensitive corporate data or personal information about business customers," said J. Alex Halderman, one of the researchers, in a press release. "Unlike many security problems, this isn't a minor flaw; it is a fundamental limitation in the way these systems were designed." The researchers successfully performed the attack on several disk encryption systems -- Apple's FileVault, Microsoft's BitLocker, as well as TrueCrypt and dm-crypt -- but said they have no reason to believe it won't work on other disk encryption systems as well, since they all share similar architectures. They released a paper about their work as well as a video demonstration of the attack (below).

Todos somos viajeros en este mundo. Desde el dulce pasto hasta el frigorífico, desde el nacimiento hasta la muerte, viajamos entre las eternidades ........ School Web LockersFrom ESchoolNews,
With many states and districts moving towards the 1:1 initiative, the question becomes, “How do we make this more cost effective for our school?” Buying personal computers for each student is expensive and difficult to maintain. Creating your own system can bog down your server and cannot be accessed outside of school due to firewall protections. So what is the best solution? School Web Lockers. School Web Lockers are web-based storage “lockers” for users to store school related files that can be accessed from any computer with an internet connection. Each student is given 100MB of storage while teachers and administrators get 1GB. Many schools are now finding these lockers an excellent solution. Terri Purcell of Orinda Intermediate School had this to say, “OIS loves School Web Lockers! This service allows students to seamlessly use technology for school projects. They start their work at school and stash it in their web locker to finish at home. Students are much more productive now. Teachers are using their Turn in Homework folder for students to upload their multimedia presentations, which makes it easy for teachers to grade them, as well as for students to access them for presentation to a group.” Students are constantly struggling with a place to store files. Most school libraries erase all files stored on the computer at the end of the day, and many schools have banned email from their server. With School Web Lockers, users don’t have to worry about losing or breaking disks or disk space and compatibility. Barbara Forster, a librarian at Dana High School, says, “School Web Lockers has solved the problem of homework and data storage in a way that allows students to access their work from any Internet-connected computer.” School Web Lockers is a user-friendly secure network. It makes managing computers easier, there’s no user administration, all outside hosting, and no system administration. Web Lockers Administrators are monitoring these sites daily making sure they are being used appropriately. School officials also have access to everything users upload and say. This service really cuts down on the use of paper. A teacher can simply upload one document and post it in every student’s locker instead of making some 30 copies of the same assignment. In turn, students can complete the assignment on the computer and upload the document into the homework due folder, which is then sent directly to the teacher. Files never override each other, so if 20 students turn in an assignment called homework1, all 20 files will appear in the teacher’s locker as homework1. Each document has the user’s name next to it and the date it was uploaded. It’s a paperless work of art. Fidel y el MarDel Periodico El Nacional,
Pablo McKinney Fidel y el mar Con la caída del Muro de Berlín en aquel noviembre de 1989, se inició el fin del siglo XX y nació, por cesárea histórica, el siglo XXI Sólo el genio carismático y legendario de este Bolívar de las Antillas puede explicar que 18 años después sobreviva un régimen considerado desde entonces anacrónico. Desde ayer y ante la cercanía de lo inevitable, Fidel no es más el presidente ni el comandante en jefe de Cuba. Esta renuncia decreta el inicio formal de la transición cubana hacia la democracia. Pero surge la pregunta: ¿hacia cuál democracia? Después de 49 años de independencia verdadera, de autodeterminación y respeto a su soberanía, el modelo impuesto por las grandes potencias a nuestras patrias bananeras no debe ser aplicado en Cuba. O sea, ni el socialismo autoritario y desfasado, pero tampoco el neocolonialismo irrespetuoso y cínico, edulcorado con el viejo cuento de la "democracia" de comillas y postalitas y más recientemente con el de la globalización y la apertura de los mercados que no de las migraciones. Ni el comunismo sordo, con su patológica falta de contemplación del otro, ni tampoco esa democracia a lo Miami, con unos señores dispuestos a repartirse esa patria en mil pedazos. Con este inicio del fin, adiós adelantado del más legendario líder político que parió la América toda en el siglo XX, comienza a llegar al puerto de La Habana la esperanza de un posible reencuentro de todas las patrias que son Cuba, la de Miami y la de la Habana, la de Madrid, la de Praga, la de Santo Domingo. No es fácil desprenderse de la admiración que generó entre los hombres y mujeres de una América morena -irrespetada siempre- la figura digna del Fidel de los heroicos años 70. A Fidel, la muerte puede borrarlo de la faz de la tierra, -esta renuncia lo anuncia- pero no de la historia. Y digo esto, porque si alguna vez en la nuestra América "no ganaron los mismos y heredaron los desheredados", fue gracias a este Quijote de las pampas caribeñas, a sus "jardines colgantes de Babilonia", que siempre respetaron y hasta admiran sus enemigos. La sombra de Fidel y su gobierno ha sido la falta de libertad; su luz más alta: su sentido de la dignidad, el respeto a una patria heroica y sus valores, y si quiere que entre el mar. Está entrando. Costoso ErrorDel Caribe CDN,
Buena parte del país, aquella que votó a su favor para evitar la reelección, se hizo la ilusión de que la segunda oportunidad puesta en bandeja de plata al presidente Fernández sería distinta. Tremendo y costoso error.
La experiencia ha sido decepcionante, puesto que en la presente administración se han copiado, y en muchos casos multiplicadas, todas las viejas y corruptas prácticas del pasado político nacional.
Lo más chocante del drama actual es la ostensible contradicción entre esas prácticas y una retórica de modernidad oficial, que en el fondo es apenas un discurso dirigido a justificar obras faraónicas y gastos sin control alguno. En tiempos que se creían equivocadamente superados se escondían, como aconsejaba Lilís, las plumas.
Balaguer se atrevía a decir que los olores pestilentes de la corrupción se detenían a las puertas de su despacho. Hoy entran en casi todas.
Los funcionarios y los dirigentes del partido oficialista no sólo se muestran indiferentes ante el derroche, sino que protegen a sus autores. Todo se le está permitido. Y todo cuanto hacen está justificado. Los que protestan por tales acciones, los que aspiran a cambios en la conducta oficial, reciben toda clase de epítetos. De pronto, los que aspiran a políticas que pongan freno a cuanto ocurre son vulgares malandrines “pepehachistas”, enemigos del progreso. Y la verdad es que si a alguien le encaja perfectamente tal estigma es a quienes incurren hoy en los mismos pecados que la nación con el voto les cobró a aquellos en las elecciones del 2004.
El presidente y su partido, que eran opuestos a la reelección, ahora se benefician de ella. Acaso no se recuerda que once diputados fueron expulsados del PLD por haber apoyado la reforma que reintrodujo la reelección en la Carta Magna. La postulación de Fernández explica el porqué él dice ahora que no se trata de un asunto de principios. Miguel Guerrero es escritor y periodista mguerrero@mgpr.com.do Mac VS PC Videos from YouTubeFrom Computer World,
February 20, 2008 (Computerworld) Apple Inc. has created several famous marketing campaigns over the years, beginning with the 1984 television ad that launched the Macintosh computer. That ad pledged that the arrival of the Apple personal computer would defeat Big Brother and thus ensure that the world described in George Orwell's novel, 1984, wouldn't come to pass. Perhaps one of the best-known ad campaigns since then is the "I'm a Mac, I'm a PC" series of advertisements that started in 2006, starring actors Justin Long and John Hodgman. In those ads, Long, playing the Mac, emerges as a better, faster and more creative system than the PC. Because of the fierce religious wars between the fans of both camps, it is not surprising that several hundred parodies of those commercials have sprung up on YouTube. Many of the parodies take the PC's point of view and make fun of the Mac as a technology better suited to making videos and Web sites than for serious business efforts. Other videos feature spin-offs on the concept -- such as "I'm a Bank, I'm a Credit Union," "I'm a Rebel, I'm a Storm Trooper" and "I'm Marvel and I'm DC." Just click on each headline to view the videos. February 20 BitMicro launches 1.6 TB DriveFrom Extreme Tech,
While other solid-state drive makers are offering 2.5-inch drives in the tens of gigabytes, Bitmicro Networks has announced a monster of a solid-state drive, at 1.6 terabytes.
The E-Disk Altima E3S320, available in a standard 3.5-inch form factor, will sample in the second quarter of 2008 and will ship in volume by the third quarter, with capacities ranging from 16GB to 1.6 TB. Is this your next PC drive? It's very, very unlikely. A call put into BitMicro for comment and pricing was not returned. However, it's probable that the drive will cost thousands of dollars. BitMicro is selling the drive into the enterprise, but also for military applications. Solid-state drives are know for their speed, but also their ruggedness
Aside from the whopping capacity, the drive is relatively mundane: of note is the Ultra 320 SCSI interface What's interesting is that, for all of its capacity, the drive uses just single-level cell flash, instead of the multi-level cell (MLC) flash that's become more common as flash endors attempt to pack more storage 10 Best Firefox ExtensionsFrom tech extreme,
Though Internet Explorer is still the most common browser today, Firefox is catching up, and it's only a matter of time before it claims the top spot. While I'm sure many people get the warm fuzzies when they use Firefox because they feel it's safer and it offers tabbed browsing (though IE7 has tabs now), I found more value in Firefox through its extensions and add-ons. Why? There are hundreds of extensions out there for everybody—tailored to your specific needs. As the Web developer for ExtremeTech, I turn to quite a few add-ons to make life a lot easier. Plus, there's plenty of other ways to enhance Firefox, even if all you care about is surfing the Web.
For this feature, I want to share with you the latest, greatest extensions Firefox has to offer. I chunked the best of the best in four categories:
These extensions were used and are compatible with Firefox 2.0. Firefox 3 is still in Beta and won't play nice with many of them. I do have to admit, having over 40 extensions will bog down Firefox a bit (though not too much), so I recommend downloading and installing MR Tech Local Install to manage your library. It will make life a lot easier. Oh, and if you don't have Firefox, download it. Ok, let's look at the best extensions for Web development. 10 Best Firefox Extensions for Web developers February 19 What are you doing in that computer Lab ?From Tech Learning,
What Are You Doing In That Computer Lab?By Larry Ferlazzo
from Educators' eZine "Experience is the name everyone gives to their mistakes"—Oscar Wilde If that's the case, I've had a lot of "experience" from bringing my students to the computer lab. For example: At times, I've used the computers as "babysitting" devices. And these are just a few of many instances that don't necessarily portray me in the best light. But I think I've learned from all of this. Our school now has a very successful after-school computer lab assisting English Language Learners, which is part of the reason that this year we were the Grand Prize Winner of the International Reading Association's Presidential Award For Reading and Technology. We've just begun several classes with our special education students using the ESL lab's model. And the same plan is being used by a large non-profit affordable housing organization, the Sacramento Mutual Housing Association, to implement ESL computer labs in all their developments. And I bring my regular English classes to the Lab often, and I think students would generally agree it's a productive, challenging, and enjoyable experience. I'd like to share a few guidelines we use to make these Computer Lab sessions successful. They are meant more as a compass, and not as a road map. I suspect that teachers with more "experience" than me have additional helpful advice that I'm hopeful they too will share. Here is just what has worked for our students: Use computers more to reinforce key concepts, and less to teach them. |
