Nintendo ressort la NES dans une version Mini inattendue !

Il s'agit de la Nintendo Classic Mini : Nintendo Entertainment System. Un nom assez alambiqué pour désigner ce qui est en fait une Mini-NES. Disponible à partir du 12 novembre prochain, cette console qui reprend l'esthétique de la Famicom, à l'échelle très réduite puisqu'elle tient dans la main et permettra de se replonger dans les jeux d'antan.

Watch This Homemade Electromagnetic Gun Vaporize A Piggybank

Now, YouTuber Ziggy Zee has created a DIY railgun. And no, as they say in the video, you won’t be finding this on Pinterest. A railgun, simply put, is an electrically powered electromagnetic gun. The U.S. military often experiments with them and NASA even once toyed with the idea of using one to launch objects into space. The backyard rail gun fires the projectile with 56 480-joule capacitors, with a burst of carbon dioxide to help it along. The railgun is the fruit of two years' work, some of which you can check out on Imgur. Typatone. What Is The Dark Web? The “dark web” is a part of the world wide web that requires special software to access.

What Is The Dark Web?

Once inside, web sites and other services can be accessed through a browser in much the same way as the normal web. However, some sites are effectively “hidden”, in that they have not been indexed by a search engine and can only be accessed if you know the address of the site. Special markets also operate within the dark web called, “darknet markets”, which mainly sell illegal products like drugs and firearms, paid for in the cryptocurrency Bitcoin. There is even a crowdfunded “Assassination Market”, where users can pay towards having someone assassinated. Because of the the dark web’s almost total anonymity, it has been the place of choice for groups wanting to stay hidden online from governments and law enforcement agencies.

Going Dark There are a number of ways to access the dark web, including the use of Tor, Freenet and I2P. 10 Amazing Science Tricks Using Liquid! Anatomy of a password disaster – Adobe’s giant-sized cryptographic blunder. One month ago today, we wrote about Adobe's giant data breach.

Anatomy of a password disaster – Adobe’s giant-sized cryptographic blunder

As far as anyone knew, including Adobe, it affected about 3,000,000 customer records, which made it sound pretty bad right from the start. But worse was to come, as recent updates to the story bumped the number of affected customers to a whopping 38,000,000. Password Security: Why the horse battery staple is not correct. I’ve intentionally kept myself from commenting on Password Security in the wake of the last month’s mass iCloud account compromise.

Password Security: Why the horse battery staple is not correct

My feeling was that this topic had already been discussed to exhaustion, and there really was nothing new about the problem that was worth discussing. However, as I read through the dozens of articles on how to choose a strong password, I realized that the majority of them are focused on trying to solve the wrong problem. We should not be incentivizing people to choose passwords in the first place. Password Strength. What Would Happen If You Were Punched By Superman? They say the Man of Steel can punch dimensions apart.

What Would Happen If You Were Punched By Superman?

If his fist has a mass of 300 grams and he moves at about 99 percent the speed of light, his punch is equivalent to 45 megatons of TNT. The movement would burn 45 trillion calories, and the energy released would be about 80 trillion Kelvin. So what would happen if he punched you? Well, first of all, you literally wouldn't see it coming. Then, he'd knock the atoms out of you, liquifying you at the atomic level.

Rombertik ‘Kamikaze Virus’ Is Inventive And Aggressive, But It’s Not The End Of The World. In human culture and warfare, the notion of self-destructive attackers like the Kamikaze pilots deployed during World War II, is pervasive.

Rombertik ‘Kamikaze Virus’ Is Inventive And Aggressive, But It’s Not The End Of The World

A more recent conflict is the cyber-war between those creating malware and the security firms and cyber-security specialists that attempt to thwart them. In this battle, the recently revealed Rombertik malware is an interesting evolution. Rombertik is a complex malware form that’s capable of pulling the pin on a grenade and taking itself and the computer on which it resides down with it as it goes. Rombertik literally self-destructs on discovery, as a means of defending itself against detection. While it’s possible to detect, the malware makes it incredibly difficult to deploy any technological countermeasures. Après Cheryl, vous aviez juré d’arrêter les maths?

What Happens When You Saw A Rubber Band Ball in Half? Terry Moore: Why is 'x' the unknown? Le train électrique le moins cher du monde. Apparently, Burning NH4Cr2O7 With HgSCN Opens A Portal To Hell. Of all the chemical reactions we've covered within the past few months, the one filmed below probaby takes the prize for coolest looking and possibly scariest. After the pile of reactants is lit, it begins to look like tentacles are crawling out of a portal to Hell. In reality, what's depicted in the video below is actually two reactions: the decomposition of ammonium dichromate and the combustion reaction of mercury (II) thiocyanate.

The orange powder is ammonium dichromate and when heat is introduced, it forms nitrogen gas, water, and ammonium (III) oxide, which is the dark powder that looks like the volcano you see. What appears to be tentacles is actually what happens when heat is introduced to mercury (II) thiocyanate. The white solid expands when it's heated to become a dark, tentacle-like mass due to its decomposition to carbon nitride.

New Record-Breaking Laser Could Dramatically Speed Up The Internet. Using microscopic semiconductor wires positioned atop a silver surface, a team of physicists from Imperial College London and the Friedrich-Schiller-Universität Jena has produced an ultra-fast laser that dramatically accelerates the interaction between light and matter.

This world record-breaking laser is exciting because one day, it could help improve data communication by boosting the speed that information can be transferred, among a variety of other potential applications. The work has been published in Nature Physics. The secret to this new super laser lies in the physicists’ use of silver surfaces, rather than the more traditional glass.

Slim layers of metal are ideal because they provide surface plasmons, which are oscillations of excited electrons that propagate along the surface of the material. When the light interacts with these waves, it can be focused more tightly than normal. Researchers Make Self-Moving Alcohol Droplets.
