Updated: July 1st at 6:30PM to add information about traffic correlation attacks.
We posted last week about the Tor Challengeand why everyone should use Tor. Since we started our Tor Challenge two weeks ago we have signed up over 1000 new Tor relays. But it appears that there are still some popular misconceptions about Tor. We would like to take this opportunity to dispel some of these common myths and misconceptions.
One of the many things that we learned from the NSA leaks is that Tor still works. According to the NSA “Tor Stinks”slides revealed by the Guardian last year, the NSA is still not able to completely circumvent the anonymity provided by Tor. They have been able to compromise certain Tor users in specific situations. Historically this has been done by finding an exploit for the Tor Browser Bundle or by exploiting a user that has misconfigured Tor. The FBIpossibly in conjunction with the NSAwas able to find one serious exploit for Firefox that lead to the takedown of Freedom Hosting and exploit of its users. Firefox was patched quickly, and no major exploits for Firefox affecting Tor users appear to have been foundsince. As the Tor developers noted in 2004, if someone is actively monitoring both your network traffic and the network traffic of the Internet service you’re communicating with, Tor can’t prevent them from deducing that you’re talking to that service. Its design does assume that at least one side of the connection isn’t being monitored by whomever you’re trying to stay private from.
We can conclude from this that Tor has probably not been broken at a cryptographic level. The best attacks on Tor are side-channel attacks on browser bugs or user misconfiguration and traffic correlation attacks.
One of the most common misconceptions we hear is that Tor is only used by criminals and pedophiles. This is simply not true! There are many types of people that use Tor. Activists use it to circumvent censorship and provide anonymity. The military uses it for secure communications and planning. Families use Tor to protect their children and preserve their privacy. Journalists use it to do research on stories and communicate securely with sources. The Tor Project website has an excellent explanation of why Tor doesn’t help criminals very much. To paraphrase: Criminals can already do bad things since they will break laws they have much better tools at their disposal than what Tor offers, such as botnets made with malware, stolen devices, identity theft, etc. In fact using Tor may help you protect yourself against some of these tactics that criminals use such as identity theft or online stalking.
You are not helping criminals by using Tor any more than you are helping criminals by using the Internet.
Another common opinion that we hear is that Tor was created by the military and so it must have a military backdoor. There is no backdoor in the Tor software. It is true that initial development of Tor was funded by the US Navy. However, it has been audited by several very smart cryptographers and security professionals who have confirmed that there is no backdoor. Tor is open source, so any programmer can take a look at the code and verify that there is nothing fishy going on. It is worked on by a team of activists who are extremely dedicated to privacy and anonymity.
As far as EFF is aware, no one in the US has been sued or prosecuted for running a Tor relay. Furthermore we do not believe that running a Tor relay is illegal under US law. This is, of course, no guarantee that you won’t be contacted by law enforcement, especially if you are running an exit relay. However EFF believes this fact so strongly that we are running our own Tor relay. You can find out more about the legalities of running a Tor relay at the Tor Challenge Legal FAQ. However, if you are going to use Tor for criminal activity (which the Tor project asks that you not do) you can create more problems for yourself if you get prosecuted. Criminal activity also brings more scrutiny on to Tor making it worse for the public as a whole.
You might think that because it is privacy software Tor must be hard to use. This is simply not true. The easiest way to get started with Tor is to download the Tor Browser Bundle. This is a browser that comes pre-configured to use Tor in a secure manner. It is easy to use and is all you need to start browsing with Tor. Another easy way to use Tor is with Tails. Tails is a live operating system that runs on a DVD or thumb drive. Tails routes your entire Internet connection through Tor. And when you shut it down, Tails forgets everything that was done while it was running.
It is true that Tor is slower than a regular Internet connection. However, the Tor developers have been doing a lot of hard work to make the Tor network faster. And it is faster today than ever before. One of the best things that can be done to speed up the Tor network is to create more relays. If you would like to contribute to making the Tor network faster, you can check out our Tor Challenge
Tor is not perfect; you can destroy your own anonymity with Tor if you use it incorrectly. That’s why it is important to always use Tor Browser Bundle or Tails and make sure that you keep your software up to date. It is also important to remember that if you log into services like Google and Facebook over Tor, those services will still be able to see your communications within their systems. Additionally Tor users should be mindful of the fact that an adversary who can see both sides of their connection may be able to perform a statistical analysis to confirm that the traffic belongs to you.
Tor is some of the strongest anonymity software that exists. We think that it is important to dispel misconceptions about it so that the public can be more informed and confident in its usefulness. There are many great reasons to use Tor and very few reasons not to. So get started with Tor, and take back your privacy online.

In order to truly answer the question of What is DNA? one has to go back to the elementary or high school biology classes.
DNA is the complex chemical that carries genetic information.
DNA dictates life in two manners:
There are elements called chromosomes in each cell of the human body. To be more precise, each cell contains 23 pairs of chromosomes.
Youll be astonished to know that some 50 to 100 thousand genes are held within these chromosomes. Since each of these genes could take value from one of the two values of its parent cells, hence you can imagine the possible variability in this structure.
These genes are made up of what is called DNA that is Deoxyribose Nucleic Acids. Apart from these genes that carry essential genetic information and only account for 2% of DNAs structure, the rest of the 98% of DNA is still a mystery.
Biologists call it junk DNA as there are no known proteins or traits that are coded or built by this part of DNA. This junk DNA, as well as the genetic information-carrying part only, varies in structure owing to the presence of four nucleotide bases throughout the DNA in differing order and sequence.
Think of these four nucleotide bases in DNA as letters that form an alphabet. Just like the way the order of letters determines the meaning of the word that is formed, the sequence of these nucleotide bases concludes what information is available for the production of proteins that consequently take an active part in the formation and growth of the body.
Most of the DNA is present within the nucleus of the cells. This is known as nuclear DNA. Mitochondria also hold a modest quantity of DNA, which is termed as mitochondrial DNA. The latter is useful in tests related to someones distant maternal lineage.
What is great about DNA is that it has a very autonomous self-replication mechanism in action. The replication process makes use of the two strands of DNA. Each of these strands acts as a template and after going through a series of steps is converted into dual stranded DNA once again. This replication is very important because when the cell divides, the newly formed cell requires the same set of instructions for it to function and grow and the replicated DNA serves this purpose.
Summing up the answer for what is DNA, it could easily be said that its a well-designed program spanning thousands of lines of codes that has instructions for everything that the cell needs to perform.
DNA, no matter how short the acronym sounds, is a vast topic that requires serious dedication of time and energy before one can grasp what it is and how it affects the life within and around us.
This article sets the foundations for a series of articles in which we will cover various aspects of DNA, the concepts, the technology and its applications. Right now, without going into the peculiar details, we are only going to briefly introduce these topics. You can think of it as a short glossary for DNA terminology.
Learning about DNA starts with a sound knowledge of what is it made up of and how these chemicals interact with each other to form a structure that builds a DNA molecule. You have to look carefully at what essential functions DNA performs in the cell that it is located in, by the way, its present in each cell of human as well as a body of living organisms.
In most basic terms, DNA is the master plan of life that works all the way from inception to growth. It holds all of the hereditary information and passes it from generation to generation.
Once you have encountered the double helix structure of DNA, as proposed by James Watson and Francis Crick in 1953, you should move on to advance topics like DNA replication. DNA replication tells us that each DNA is able to produce an exact copy of itself and this is made possible with the help of DNA polymerase, an enzyme that takes an active role in the process. Youll also come across DNA synthesis, which is an artificial technique to produce copies of DNA and is based on the concept of DNA replication.
While DNA holds all of the information required for the cell to perform its actions and produce the essential proteins, it is important to note that DNA doesnt interfere directly with the elements of cytoplasm outside the cell nucleus and disseminates this useful information through a messenger RNA. This is done through a process called DNA transcription.
The buzz words that have really boosted the popularity of DNA among the masses are DNA cloning and DNA testing. Who has not heard of Dolly, the first ever cloned animal? DNA testing, owing to a large number of social, commercial and forensic uses, has drawn the attention towards further studies and research in DNA.
DNA is the short term for Deoxyribonucleic Acid. Almost every cell in an individuals body has the same DNA, as the DNA is located in the cell nucleons. People, most of the times, learn what is DNA and its importance for the human body, in school.
Anyway, properly understanding what DNA is, is always important, mostly if you are working in areas in which DNA results have importance on the evolution of some cases. For starter, to understand what is DNA, you need to know that it contains all the information used in the development and functioning of all living organisms.
What is the structure of DNA, is also a common question that people seem to ask?
Human DNA consists of about 3 billion bases and more than 99 percent of them are the same, for all individuals. Another important aspect of what is DNA is that it can replicate and make copies of itself. The use of DNA linked information has become more important in science and medicine, as researchers have found that it can be used to cure diseases, or better said to avoid babies from inheriting diseases their parents are suffering from. This currently, is considered to be a major goal for scientists, who are searching for treatments, cure and also for prevention when it comes to genetic conditions. DNA becomes even more important for people who think that such risks are higher in their particular cases.
Researchers aim to detect individuals who are predisposed to develop such diseases and that means that scientists can find treatments, to be used for the purpose to prevent genetic conditions. DNA is simple to understand, but the way DNA functions is more complex.
The discovery of DNA, in fact, revolutionized both science and medicine, having numerous effects on other linked domains, such as legal and social areas. Samples of DNA are, all the times, taken from the scene of a crime, and it is a safe way to find and convict criminals, being an accepted and trusted evidence in court.
What is DNA can be easily answered when you understand that it transfers hereditary information from one generation to another, determining, at the same time, the structure of cells.

Saltwater Fishing Charters by Lagooner Fishing Guides
Thursday August 25, 2016
Canaveral Florida host some of the best charter Captains in the world and Lagooner Fishing Guide Captain Richard Bradley is right in amongst them. If the weather’s nice and the seas are fair you’ll experience the Atlantic Ocean on Florida’s East Coast offering awesome King Mackerel action, seasonal mahi mahi or dorado, cobia, sailfish, grouper, snapper and tripletail like the ones displayed above this summer. There are days when the fish are biting so hard that you literally can’t cast a second rod because the first one’s already hooked up and running around the boat at breakneck speeds!
“Fishing offshore near Cape Canaveral between Daytona Beach and Fort Pierce, Florida has so much variety for anglers.” Explains Captain Richard Bradley “If you are vacationing in Orlando or near it’s theme parks Disney, Universal Studios, you’ll not want to miss a day of action on the water catching fish and soaking up Florida’s sunshine.”
Picking an offshore fishing destination is easy in Central Florida as Port Canaveral is absolutely the best bet with the large variety of fish and habitat. Choosing a Charter Fishing Captain is just as easy too… Captain Richard Bradley has over 40 years fishing experience out of Port Canaveral and Cocoa Beach area and is well qualified and full time. “If you’re choosing a Charter Captain, look for a full time, licensed and insured Captain” explains Captain Gina. “We see so many part time illegal fishing guides in our area that have no clue about how to take care of their customers and make a difference in a fishing day. Safety and success are our main concern and it’s not just about making a boat payment or extra money for us, it’s about making a lively hood and doing it RIGHT.” Our website reflects what we believe so take a look around and you’ll see quality in everything we do.
Offshore of Cocoa Beach and Port Canaveral’s beaches are countless reefs, rocks, ridges and wrecks for the fishing enthusiast to explore. Hiring an experienced and knowledgeable local fishing guide offers the best opportunity for anglers to hookup with many of the local species of saltwater fish like the powerful Jack Crevelle or aerobatic tarpon. Venturing further offshore offers anglers deeper water species like Snapper, Grouper, Sailfish and Dolphin. Simply ask your Charter Fishing Captain what’s biting and follow his lead to the best bite in Central Florida’s offshore waters.
Hello, I’m Captain Gina Bradley from East Central Florida in Cocoa Beach. My husband, Captain Richard takes me offshore fishing all summer long for hard fighting and reel striping action that really makes for a wonderful day for this outdoors girl.
You really can’t go wrong on Florida’s east coast during the summer. The temperatures on the ocean are cooler than inshore and the fishing is fabulous and fast paced on most days. Captain Richard is an expert and knows how to put his anglers on the fish and you’ll enjoy his enthusiasm and love for the outdoors.
Call me today and set up your offshore fishing trip in Central Florida Today!
Captain Gina Bradley Lagooner Booking Agent / 321-868-4953
It’s Summer….! Offshore fishing in the summer in this part of Florida can be the most fun a family or serious anglers can have. Whether you’re looking to sightfish for cobia or live bait for king mackerel and other offshore game fish, it’s usually calm and hot in the summer months out of Port Canaveral. Typically summer fishing tends to slow down in the mid summer in the lagoons and gets really good offshore so it’s a great time to change the scene and head out to the deep blue abyss for some hard fighting action.

First-time flier Kate Rubins and veteran spacewalker Jeff Williams will venture outside the International Space Station this morning (Aug. 19) to install a massive, crucial piece of machinery:a vital new docking port that will allow private space taxis to link up with the station on future missions.
The spacewalk is slated to begin at 8:05 a.m. EDT (1205 GMT), NASA officials said during a news briefing. You can watch the spacewalk live here on Space.com, courtesy of NASA TV.
This spacewalk marks a first for Rubins, and the fourth of Williams’ career. The two astronauts plan to spend about 6.5 hours outside the station installing this new heavy piece of machinery, known as an International Docking Adapter (IDA), which arrived at the station on July 20 aboard a SpaceX Dragon cargo spacecraft. [The Most Memorable Spacewalks in History (Photo Gallery)]
The IDA being installed today is the first of two devices that will be attached to the space station as part of a new international standard that allows a variety of vehicles to dock with the orbiting lab independently rather than being grappled with the station’s robotic arm.
Williams, Expedition 48’s commander, will head out first, and Rubins will hand off a bag of IDA installation tools before stepping outside the station.
“This EVA [spacewalk] that we are going to be doing on Friday represents a very significant milestone on the path to establishing a commercial crew capability on board the ISS,” Kenny Todd, the station’s mission operations integration manager, said at the news briefing Monday (Aug. 15). “We’re very excited to put this piece of hardware on the front of the station.”
Astronauts Kate Rubins and Jeff Williams are all set to venture outside the International Space Station (ISS) tomorrow (Aug. 19) to install the first International Docking Adapter. This addition to the ISS will allow future private space vehicles to hook up to the station.
Multiple previous spacewalks paved the way for today’s installation. During four EVAs (extravehicular activity) performed earlier this year, and in 2015, astronauts routed cables for the docking adapter and installed a control panel, among other maintenance tasks.
On Wednesday (Aug. 17), the ground robotics team successfully removed the IDA from the Dragon spacecraft’s trunk using the space station’s robotic arm, and positioned it 3 feet (0.9 meters) from the front of the port. This morning, prior to the start of the spacewalk, the ground crew used the arm to move the IDA closer to the port, so that it would be ready to be installed by Williams and Rubins.
The International Docking Adapter as seen before its launch to the International Space Station.
The new IDA, which measures 7.8 feet (2.4 m) in diameter, will allow for larger crews to launch from all different places around Earth and dock with the space station automatically. Boeing and SpaceX have contracts with NASA to send astronauts to the space station in 2017.
If all goes according to plan, the spacewalkers will complete some additional tasks after hooking up the IDA. Williams and Rubins will install thermal covers, as well as set up mirrors that will allow future space taxis to autonomously navigate, align and connect with the space station properly. The team will also route some additional cables for the second docking adapter, which is expected to fly up to the space station next year.

On Sept. 1, a second EVA will be conducted to perform more work on the IDA, during which astronauts will retract one of the station’s thermal radiators.
Williams and Rubins are part of a six-member space station crew. They arrived at the station on July 9, and are joined by Japanese astronaut Takuya Onishi and Russian cosmonauts Oleg Skripochka, Alexey Ovchinin and Anatoly Ivanishin.

Lo que usted obtiene:
GNU Linux, Mac OS, Microsoft Windows y otros programas compatibles.:
Jitsi est disponible para GNU Linux y Mac OS, as como para MS Windows (y prximamente para Android OS). A continuacin se recomiendan otros programas con los que Jitsi se puede comunicar usando el cifrado independiente OTR o ZRTP:
Para mensajes de texto: Pidgin (MS Windows y GNU Linux), Miranda (MS Windows), Adium (Mac OS X), ChatSecure (Android OS y iOS, conocido anteriormente como Gibberbot).
Para llamadas de voz: CSipSimple (Android OS), Linphone (GNU Linux, MS Windows, Mac OS X, Android OS, iOS y otros).
1.1 Cosas que debera saber acerca de esta herramienta antes de comenzar
Jitsi es compatible con diferentes tipos de cuentas y protocolos de comunicacin y, por lo tanto, puede comunicarse con contactos que utilicen otros programas. Algunos de esos programas ofrecen funciones similares para mejorar la seguridad de su comunicacin (como los programas mencionados en la seccin anterior), y soportan el cifrado independiente de texto y voz (OTR y ZRTP). Otros programas podran no tener implementadas estas funciones, especialmente los propios (por ejemplo, el chat de Facebook o Google Talk). Sin embargo, con Jitsi podr comunicarse de todas formas con contactos que utilicen dichos programas propios, slo que sin los beneficios adicionales de las funciones de seguridad de Jitsi.
Sin importar si se comunica mediante texto, voz o vdeo, los proveedores de servicios como Facebook Chat, Google Talk, Yahoo! Messenger, Skype o Viber tienen acceso a sus sesiones de comunicacin y pueden ofrecer el acceso a terceros, tales como corporaciones o gobiernos. Jitsi le permite comunicarse de manera segura y privada usando sus cuentas existentes con la ayuda de un cifrado adicional. Esto hace que el contenido de sus comunicaciones sea inaccesible para los proveedores de cuentas y posibles terceros. Para poder proteger sus sesiones de chat y conversaciones privadas, Jitsi utiliza mtodos criptogrficos, inclusive Off-the-Record (OTR) para conversaciones de texto, y ZRTP/SRTP para llamadas de voz.
Otra diferencia a notar entre Jitsi y programas como Skype es que Jitsi permite que los usuarios sigan usando sus cuentas existentes con un proveedor de servicio distinto, independiente de los desarrolladores del programa. Esto tambin significa que necesita configurar una cuenta antes de poder utilizar Jitsi.
Nota: Jitsi utiliza el lenguaje de programacin Java, de forma que el programa Java debe estar instalado en el equipo para que funcione. Se sabe que Oracle Java tiene varias vulnerabilidades de seguridad que pueden permitir que usuarios remotos tomen control del equipo e instalen spyware para acceder o controlar todos sus datos y comunicaciones. Se recomienda ampliamente que minimice el nmero de programas que tienen permitido utilizar Java en su equipo. Mire cmo desactivar complementos asociados con Java en Firefox y consulte los pasos para deshabilitar Java en todos los navegadores del equipo. Sin embargo, como ver ms adelante en este captulo, a pesar del uso de Java, hay una serie de beneficios de seguridad al utilizar Jitsi.

LSD is the most widely studied psychedelic, with hundreds of published research papers (see below). An LSD experience is similar in many ways to psilocybin mushrooms, but often individuals feel like they are better able to direct and control the experience.
LSD studies have shown success in treating depression, anxiety, smoking cessation, and many other psychological conditions. LSD consistently produces powerful long-term improvements in these conditions, even with just a single dose.
Before you begin, be sure to read our safety section and see the special safety considerations for LSD at the bottom of this page.
LSD is a powerful chemical and taking the correct dose is essential. Because LSD is active at very, very small quantities and because it is typically delivered on small pieces of paper, it is difficult to independently assess the dose (this issue is less of a problem with mushrooms or MDMA). Taking too much LSD can lead to feelings of dissociation and alienation.
Be sure that you know the dose that you are taking. A single dose or tab of LSD can vary widely in strength, so make sure you know the quantity in micrograms. A 100ug dose is a good starting point if you have never taken LSD before and should provide a calm and opening experience. If you are interested in deeper psychological work or spiritual exploration, and have a lot of experience at lower does, you may decide to move up to 400 or 500ug, but only do so if you are very comfortable with lower doses. Do not use LSD unless you are very confident of the quality and dose that you have. Its best to use a source that someone you know has also used and can vouch for.
LSD will typically be delivered on small pieces of paper that the LSD is diffused onto. It may also be provided in liquid or pill form, or even diffused into a sugar cube.
Typically, people feel very free and open in the days following an LSD experience. Remember that you need at least 12 hours before you try to sleep, so if you begin too late in the day, you may have some trouble falling asleep and could be a little tired the next day.
Most people find that they have an afterglow from their LSD experience that can last days or weeks, improving their mood and outlook and keeping them very open to others. Ideas and issues that you explored during the experience will have a new clarity too them. Emotionally difficult topics, memories, and experiences are likely to feel much safer and will bring up less fear when you remember them. You are likely to feel better able to tackle challenging emotional experiences in your life.
LSD has been shown in many research settings to dramatically reduce anxiety, depression, and other psychological challenges with just a single dose. However, you may wish to repeat the experience a few times to further explore and address any emotional and psychological issues that you are working with.
In addition to our standard safety guidelines, there are two particularly important precautions for LSD use:
