Check open ports router

At one time or another we have all been forced to open a port on your router (port forwarding): improving the download speed in emule, enable remote connection to vnc, ssh access ...

And when it does not work there is always the same question: are you really open the port? How to check which ports are open?

This is where this article: how to check port status easily.

The solution we propose is independent of the operating system so it can be used by both pro Linux users and by those who are "forced" to use the "small window" of Redmond.

Also we will not have to install any software on our team because we will use a website that helps us work: WhatsMyIP.

Among the options included is the ability to scan the ports used by games and common applications (including P2P) option but personally I find it more comfortable is to enter the port number you want to check at the entrance to Port Custom Test and after clicking the Check Port check if the port is actually open I'm setting in my firewall.

It is very intuitive to use because if the port is open tell us putting green background to highlight everything's OK in a quick and easy

night spiderweb

A weaver spider rests at the center of its web orbicular. A wasp comes and gives you a pang. The spider is paralyzed for 10 to 15 minutes. Meanwhile, the wasp egg attaches to the abdomen. When the spider is recovered, resumed his normal activities and one or two weeks continuing to build normal orb webs to capture prey on which it feeds. But in his abdomen of the wasp egg ends up producing a larva which will remain attached to the spider, vampire feeding in miniature hemolymph of the spider, which will suck for a few small holes made in the abdominal cuticle of it.

And here comes the incident. One night, when the wasp larva reaches the stage of development in cuticle molting for the first time, induces the spider to build a web abnormal, consisting only of guidewires, the larvae use for their own purposes. Then, the larva moves back cuticle, the spider kills and devours. The next afternoon, the larva spins a cocoon and hangs it on the special web spider wove enslaved and who happens to be a structure particularly well designed to support the bud. The larvae pupate after about four days and seven other emerges already become adult wasps.

This is a story of real life. The drama occurs between the spider Plesiometa argyra (Walckenaer 1841) (Tetragnathidae) and the wasp Hymenoepimecis argyraphaga Gauld (Ichneumonidae). It is one of many examples of parasites that take over the behavior of their hosts and force them to perform actions necessary for the parasite to continue or complete their life cycle.

In several studies published last year, giving details of the domain that carries the fungus on its host unilateralis Ophiocordyceps, the carpenter ant Camponotus leonardi, which forces you to die ideal area for growth and reproduction of the parasite itself.

The bite of death

When the fungus infects the ant, it continues to live for a short time, but his behavior becomes suicidal. Foliage leaves high in the lives normally, more than 20 feet above the ground, and down the saplings and smaller plants, there are moves under a sheet hanging near the floor and attaches it to the jaws. It is well for weeks, his jaw locked in what has been called the bite of death. When the ants finally dies, the fungus is growing inside your body. After several days, the stroma of the fungus sprouts grotesquely behind the head of the ant, to shed one or two weeks later, a shower of spores capable of infecting each another unfortunate ant.

In photographs taken of the study (link) Maj-Britt Pontoppidan and other researchers cite the end of this note is (up) a sheet with a dead ant against the backdrop of forest and (bottom) with Ant stroma of the fungus coming out behind the head. The second picture was so up and down so that it can be more parasite and host.

Infection, "says researcher David P. Hughes, Harvard University, must occur on the forest floor, because the spores of O. unilateralis are too heavy to disperse over long distances. Rather, create an area of ​​infection of about one square meter below the dead host.

Although this example has been known for nearly a century, recent studies reveal how accurate is the government that exercises the fungus over his victim. Almost invariably, researchers found the ants clinging to leaves located at about 25 inches off the ground and on the northwest side of the plant. Apparently, humidity, lighting and temperature are hence the ideal for the growth and reproduction of the fungus. When the researchers removed some infected ants in that area and highest ranked sites, the mushrooms did not develop properly.

It is also notable that grows in the dead ant, the fungus converts it into sugars entrails, with which it feeds, but never touches the muscles that move the jaws, so that they remain locked to the blade.

Recently discovered for the first time convincing evidence that the parasite has been operating in the same way for about 48 million years. Fossil leaves collected in Messel, Germany, presents the characteristics of the bite marks of death. This is probably the oldest evidence of such parasitism. In this note Smithsonian Science (link) you will find more information.

There are many other examples, as I noted above. One or two until it sounds funny. There is a nematode parasite of an ant, her abdomen swells and puts it bright red like a cherry. Then the ant does lie belly up including strawberries to wait to eat it the bird which is the definitive host of the nematode. And there is a protozoan, Toxoplasma gondii, which must pass an intermediate host, a rat, in its final host, a cat. To do so, reverses the rat's innate aversion to cat odor and makes them attracted to it, with consequences that are to be expected.

The big question is how the parasite manages to change so radical and yet so specifically, the behavior of its host. The answers will surely come of biochemistry. The parasite may secrete neuroactive substances or that in some way, directly or indirectly, alters the levels of certain hormones and neurotransmitters of the host. In several cases it has checked the profile modification of protein synthesis, the researchers already have his eye on several proteins that may be involved in modifying the behavior of victims. Obviously this is a very complex and fascinating field of study.

Google a button to block those results we do not want to reappear in future searches

The company headed by Eric Schmidt introduced a new tool for your browser that will block sites that do not want to re-appear on our lists of results.

Fingerprint - Control to lock pages in Google searches

Usual, and many of us we will have passed when we are doing an operation with this search engine, which appear as results pages that have nothing to do with what we want, including some to which we are never going to be interested in entering. As clarified in the company blog: pages that can have low-quality content, offensive or pornographic.

For this is that included in Google a button to block those results we do not want to reappear in future searches. One performs the search and when you return to the home page, see this option: "block all results." Is confirmed and ready.

Keep in mind that this blockade is for the previous search has been done and will begin to be operational from the next search. Of course, this block does not have to be for life. If at any time the user decides to include some pages that have previously blocked, you can. There is an option that will appear in the pages can be blocked and that all the details of the blocked sites, and even unlock them.

For now, this tool is only available in the browser version in English, although it is assumed that in the short term will be available in other languages, and Castilian. As for the versions of the browser in which you can use this option are from Google Chrome 9, IE8 and Firefox 3.5.

Engineers, reflecting a crisis of manpower

Late last summer, 36000 Germany sought engineers, reflecting a crisis of manpower in the industrial sector (as is also needed cooks, administrative personnel, auxiliary nursing homes ...), and looking abroad. And still looking for more engineers and other workers from beyond the borders Germanic to hold the Bavarian economy.

© Neotakezo

Or if not, why recently, Chancellor Angela Merkel spoke of seeking engineers and others in countries like America?

It must be said clearly, an engineer in America does not have many opportunities to do everything I wanted and less likely to receive remuneration for their skills (hence it is spoken in some parts of "over-" and reach the end of lying less in the curriculum, will be the master engineer require astronomical salaries ...) ... and that if he found a job, of course. I'm in the position of having been lucky enough to find work (yes, nearly a year and a half after finishing the race) and even now I'm even below mileurista and I do all that is supposed to be a telecommunications engineer to do, I can at least begin to have experience in the ICT sector ...

... One area that America continues to look with disdain (or fear, you choose what seems best) over his shoulder as he insisted that the brick should be the engine of our country on the services sector. It is true that the service sector is always a good asset for our country, but have not seen the real estate disaster, which has worsened in America which is in itself a global crisis? And what is this apparent technophobia that is in the Spanish political class that instead of investing more in R & D, technology and other cost-cutting decide from there?

Today we speak half in jest, half seriously, "Come to Germany, engineer Pepe," recalling the title of one of our most famous films and Spanish society half a century ago, to migrate to Germany for a better future. And is the situation we are considering for many young graduates, who see in this country know any achievements like everything related to technology and science.

And there is talk of a brain drain over! Of course, the concept of "brain drain" has always been treated as if America was removed a knowledge capital and important talent. However, this is not the case.

And some will say "but if you are saying that the Spanish engineers will go to Germany because there are job offers, is not that a brain drain?" And I answer with another question: "what do those engineers in America aside from looking for non-stop and end up in jobs that have little or nothing to do with yours? ".

Because that's the point: we have meat, consultancies, technology companies several, but not so many and so important in America. The brick still outweigh science and technology together. So do not talk about brain drain, because at first glance America should have some concern for engineering and science (in capitals). And clearly does not. If not, many engineers would not seriously thinking of moving to another country and learn their language if that can develop as workers, engineers and people.

There is much potential in our country. There is a great potential, and although our universities than those displayed in world rankings, at least not useless institutions as some may think. The problem is not in college, but that sales once you realize that what they have you made is being exploited in an inefficient way (rather poor) in our country. And yet I was surprised to see that many want to go to Germany, as decades ago?

Repair requires creativity * Repair * Repair is Green is fun
Repair is necessary to understand our stuff * Fix saving money and resources

We have the right to:
Open and repair our things if they void the warranty
Appliances that can be opened * error codes and wiring diagrams

LCD TV technology today.

f this does not get you excited, then nothing will. LCD TVs have become all the rage and there is nothing better than a big screen TV. And when two LCD TV with HDTV, watch out. An amazing physical display combined with exceptional power. This is what is happening in LCD TV technology today.

If you're like most people looking to replace your TV, you've probably been paying attention to High Definition Television (HD-TV). Unlike the previous generation of television, which uses analog signals to transmit information, HD-TVs use digital signals to transmit a signal and receive and display information directly on the TV. The HD-TV also use a set of high resolution digital TV and Dolby Digital surround sound. Combining the two creates incredible pictures and sounds - the best available in the market to date. HD-TV television offers viewers a level of detail not seen before: as a resolution five times higher than analog TV.

The main thing to remember when you are shopping for HD-TV group is that just because television is "digital" does not mean it necessarily "HD-compatible TV." There are two levels below the HD level (standard definition TV and enhanced definition TV), which are much better than analog televisions but much lower quality than an LCD TV HD-TV. Since the FCC has mandated that all televisions eventually switch from analog to digital, you should know the differences between different types of digital TVs.

Here are some tips. When looking to buy a HD-TV, be sure to compare the difference in image resolution, audio features and pixels. HD-TV requires a minimum of 720 horizontal scanning lines (enhanced definition TV, while considerably higher than standard definition television, only with a minimum of 480 scanning lines) and the resolution of a HD-TV is of 1920 x 1080 compared to enhanced definition television, which only has a resolution of 1280 x 780.

When you have an HD-TV image and then compare it to other TV technology on the market, the difference will be clear. With "HD" everything looks and sounds much more realistic than any other system. We believe that once you see a big screen LCD TV with HD-TV, the choice is clear.

This is only the tip of the iceberg in the search for high-definition LCD TV. In fact, many of the most important tips not mentioned here. Learn about LCD TVs before making a purchase.

I bet you thought I was dead!

In my wanders through the many pages of the Internets, I came across several things that really boggled my mind, now I like to consider myself reasonably well read and that I have a pretty good grasp on the English language, and only want to throttle it occasionally.

I do understand that for some people English is a bit hard to grasp hold of and that it is filled with words that look alike, but have vastly different meanings, for the average person I can understand making a mistake, but when I come across certain words on a professional business site, as well as within the confines of a published authoritative piece, I start to wonder.

The three words that have garnered my attention for the most amazing misuse within recent memory are COMMENSURATE, COMMISERATE and COMMEMORATE.

Commensurate means:

1. having the same measure; of equal extent or duration.
2. corresponding in amount, magnitude, or degree: Your paycheck should be commensurate with the amount of time worked.
3. proportionate; adequate.
4. having a common measure; commensurable.

Commiserate means:

1. to feel or express sorrow or sympathy for; empathize with; pity.

Commemorate means:

1. to serve as a memorial or reminder of
2. to honor the memory of by some observance
3. to make honorable mention of.

So when I saw a business offering a sale for the ANZAC day long weekend holiday with the banner:-

“To commiserate the ANZAC long weekend, all items 20% off”.
I nearly fell out of my chair, that word, it does not mean what you think it means.

I started to wonder if this was just an isolated incident, but Google got me many hundreds if not thousands of cases where people have used these three words interchangeably, I saw lots of questions posed along the lines of :

“Is your pay commemorate with your experience?”

and even:

“We gathered to commensurate the occasion with a few drinks and a song or two“

If anyone feels like commiserating with me over the commensurate angst I felt upon reading all those errors, then we could commemorate the occasion with a wild HUZZAH or two.

Adobe makes Flash= HTML5

After the battle with Apple over the lack of Flash on mobile devices like the iPhone and iPad, Adobe chose to join the enemy and opened Wallaby, a software that converts files to Adobe Flash Professional Flash CS5 to HTML5.

The aim of the Wallaby software is meeting the standards while reaching to all devices that do not accept content in Flash format, such as Apple's mobile devices with IOS.

"Wallaby is an experimental technology that demonstrates the innovation that we are about Flash and HTML and investment shows that we are devoting to both technologies, which we consider of equal importance, " said senior product manager for Adobe Creative Suite, Tom Barclay .

The Wallaby performance is simple. Simply drag the Flash file within the program and it will convert to an HTML file, which will achieve the same effects as in the original Flash file.

For now the product is under development, so only you can convert some types of files.

Britney Naked

Fernando Flores, a bodyguard who claims to have been sexually harassed by Britney Spears, now says the singer sent him photographs that appeared nude.

In June last year revealed that Flores had been bothered by Britney when she worked with her and planned to sue.

Months later, Flores gave further details and said the singer was waiting naked in bed.

Now, according to thesun.co.uk, the bodyguard said that it will release the photographs that Britney sent him on his cell phone as evidence in court that he suffered harassment.

People close to Flores, who say they have seen the images, say they are quite explicit and disgusted most of their fans.

Girl Gets angry after losing radio Contest

Facebook Dog

Facebook founder Mark Zuckerberg, has created a profile on the social network for your dog, named Beast (Beast) and within hours got to have more than 800 "friends."

Zuckerberg, 26, calls for greater exposure of private life and offers a taste of it this way: The profile of dog shows numerous photos of the pet with the founder of Facebook and his girlfriend Priscilla Chan.

In the past, Facebook has criticized some negligence in the management of private data network users. During a change of network configuration had private photos of users who were mistakenly view of everyone, including Zuckerberg's own shadow.

Meanwhile, Facebook already offers possibilities much more specific and detailed to separate the private from the public for each user.

It's like a Kodak moment on steroids

NASA finds life

A NASA astrobiologist claims to have found proof of existence of life outside Earth after finding fossil evidence of bacteria in a rare class of meteorites, published the Journal of Cosmology.

Dr. Richard B. Hoover, Marshall Space Center of the U.S. space agency (NASA), said he interpreted this finding as "a sign that life is more widely distributed and can not be restricted to the Earth."

In comments reported by FoxNews Channel, Hoover said, "This is a barely explored field of study because, frankly, many great scientists would say it's impossible."

NASA scientist drew these conclusions after studying more than a decade of extremely rare type of meteorites, the CI1, in remote areas like Antarctica, Siberia and Alaska, of which there are only nine in the Earth.

Hoover's article explains the findings of fossil evidence of bacteria similar to those known on Earth, but also traces of unknown microorganisms in these meteorites.

"The exciting thing is" that in many cases are recognizable and can be related to generic species already known, but some are really strange and not look like anything that can identify, "he said.

Hoover said that these rare specimens they have been taught to other experts and "also have been puzzled."

In anticipation of the controversy that may generate this discovery, Dr. Rudy Schild of the Harvard-Smithsonian Center for Astrophysics and editor of the Journal of Cosmology, invited members of the scientific community to comment on the article by Hoover.

"Given the controversial nature of discovery, we invited 100 experts and launched an additional invitation to more than 5 thousand scientists to review the article and offer their critical analysis," wrote Schild on the website of the Journal of cosmology.

Schild said that the intention of the magazine is adding to the Hoover article comments submitted by other scientists, both pro and con.

According to the Journal of Cosmology, "the careful analysis of Dr. Hoover provide definitive evidence of ancient microbial life in astral bodies, some of which may predate the origin of the Earth and solar system."

Hoover was aware of the controversy and skepticism that can generate a discovery of this magnitude.

"Sometimes it takes a long time before scientists change their way of thinking about what is true and what is not. I'm sure there will be many scientists who were skeptical, "he added.

Glory loss confirmed

NASA confirmed on Friday the loss of its satellite Glory after the failed launch of the Taurus rocket from the Vandenberg base LX the U.S. Air Force in California.

The rocket blasted off at 11:09 local time and almost six minutes later failed during the second stage of the launcher. Data received from the device indicates that the call was not opened cap, ie the cone of the tip of the rocket where the satellite will stay during the ascent through the atmosphere and to be opened in two halves to release the device, with engaged coping, overweight prevented the placement in orbit of Glory, according to preliminary reports from NASA yet to fully explore all the information for a definitive diagnosis of the fault. It is assumed that the satellite fell into the Pacific Ocean, but has not yet been able to determine the exact location. "We missed the launch into orbit, it appears that the satellite and the rocket ended up somewhere in the Pacific," said launch director Omar Baez.

Scar located on Mars

The Mars Express Orbiter photographed in high resolution scar 78 miles long and up to 25 kilometers wide, located south of Crater Huygens on Mars, and produced by the impact of a meteor shower.

The pictures, published by the European Space Agency (ESA) show in detail the crater have reached as deep as 2000 meters in some places.

The agency said in a statement that the three most profound that can be seen in the photographs are evidence of a possible straight drop of several rocky projectiles.

In addition, the two depressions in the crater with elongated "reinforce the idea of a rain of bullets," he said ESA satellite which photographed the area of Mars on 4 August.

North of that scar is the famous crater called Huygens, of 456 kilometers long, named after the Dutch physicist and astronomer Christiaan Huygens, who discovered Saturn's moon Titan.
