Un astrophotographe amateur réalise le plus grand panorama interactif du cielUn Américain de 28 ans, Nick Risinger, a fait plus de 96.500 kilomètres dans le but de créer un panorama du ciel de 360° entièrement interactif. Il s’agit de la plus grande carte de la voûte céleste réalisée à ce jour.La Voie Lactée et ses planètes, étoiles et fascinantes nébuleuses… Le résultat final du panorama interactif réalisé par Nick Risinger, est impressionnant. Ex-directeur de marketing à Seattle, l’Américain a parcouru près de 100.000 kilomètres dans l’ouest des Etats-Unis et en Afrique du Sud pour réaliser cette carte, la plus grande image nocturne et en couleurs du ciel.

Au total, 37.000 images ont été assemblées pour former ce panorama interactif à 360° de 5.000 mégapixels. La première photographie a été prise dans le désert du Nevada. Puis l’homme, accompagné de son père, s’est rendu dans l’Arizona, au Texas et en Caroline du Nord. A chaque fois, l’endroit privilégié se trouve le plus loin possible de la ville et de la pollution. Quant aux photographies de l’hémisphère sud, celles-ci ont été prises en Afrique du Sud. Nick Risinger s’y est rendu deux fois pour ce projet.A son retour à Seattle, l’Américain a utilisé plusieurs logiciels destinés à l’astrophotographie pour enlever le bruit, superposer les clichés de trois couleurs différentes et assembler scrupuleusement les images selon des repères, pour recréer la voûte céleste.Nick Risinger, qui souhaitait avant tout “éduquer et éclairer les gens sur la beauté naturelle qui les entoure”, a fait très fort. Non seulement son travail est à couper le souffle, mais sa nouvelle carte interactive dépasserait toutes les cartographies professionnelles réalisées jusqu’à présent.L’astrophotographe a déclaré au site Wired : “Je voulais créer quelque chose qui soit une véritable représentation de la façon dont on pourrait voir [le ciel] s’il était 3.000 fois plus brillant”.Le 4 mai 2011 à 16:59 • Emmanuel Perrin

Bayern Munich forward Thomas Muller believes that they can use the pain of last season’s Champions League semi-final exit to prompt them to glory this time aroundThe Bundesliga champions were eliminated in the last four of last season’s competition at the hands of eventual winners Real Madrid.Now, under new coach Niko Kovac, Bayern are hoping to lift their first European Cup since 2013, when they won against German rivals Borussia Dortmund in the final.“We all know that we could have won the trophy,” Muller told Sport Bild.Merson believes Arsenal should sign Sancho Manuel R. Medina – September 14, 2019 Borussia Dortmund winger Jadon Sancho might be the perfect player to play for the Gunners, according to former England international Paul Merson.“We are seething with anger and in Niko Kovac we have a new, young and aspiring coach.“Hopefully, this year we will for once have the full squad available from March to May. Everything’s possible for us in that case.”Bayern have been drawn with Ajax, AEK Athens and Benfica in Group E of the 2018/19 Champions League.For now though, the Bavarians will return to action this weekend by hosting Bayer Leverkusen.

Google employees held a worldwide walkout last year. Getty A memo written by a Google employee, which alleges she was targeted with discrimination and retaliation during her pregnancy, has gone viral within the company, according to a report Monday by Motherboard. The 2,300-word memo, titled “I’m Not Returning to Google After Maternity Leave, and Here is Why,” was posted on internal message boards at the company and viewed by more than 10,000 people, Motherboard said. The document, which was posted by Motherboard with the author’s name redacted, says the writer’s manager had made inappropriate comments about pregnant women in the past. When the writer — who was also a manager — reported her own manager to human resources, she reportedly experienced retaliation. When the writer was getting ready to go on maternity leave herself, she says her boss said she wouldn’t be guaranteed her managerial role when she returned. “I’m sharing this statement because I hope it informs needed change in how Google handles discrimination, harassment and retaliation,” the memo reads. “Also, if anything similar has happened to you, know that you’re not alone.”Google on Monday didn’t address the memo, but said it doesn’t condone retaliation. “We prohibit retaliation in the workplace and publicly share our very clear policy,” a Google spokeswoman said in a statement. “To make sure that no complaint raised goes unheard at Google, we give employees multiple channels to report concerns, including anonymously, and investigate all allegations of retaliation.”Google has faced allegations of retaliation in the past. In November, Google employees held a massive walkout over the company’s handling of sexual harassment allegations targeted at key executives. Two of the walkout organizers, Claire Stapleton and Meredith Whittaker, said they faced retaliation from management for their organizing efforts. Stapleton departed the company in June and Whittaker left last month. Post a comment 0 Tags Share your voice Google Alphabet Inc. Tech Industry

Credit: Advanced Materials (2018). DOI: 10.1002/adma.201800429 As medical scientists continue to look for new ways to study living beings, many are studying the possibility of putting miniature objects inside of a living organism that can carry drugs or perform actions such as blocking blood vessels that feed tumors. Some have taken the science even further by creating objects small enough to fit inside a single cell. Such objects could conceivably carry drugs directly to individual parts of a cell. But, as the researchers with this new effort report, prior efforts have resulted in disruption to the cell, preventing the use of such devices. They report that they have now developed a nanomotor that can be guided to desired locations inside of a cell without causing disruptions.The nanomotor was made mostly of silica, the team reports, but was covered with a very thin iron film to allow for control by magnetism. The nanomotor is shaped like a corkscrew, which means when it spins, it moves forward. A spinning external coil that generated a magnetic field induced the nanomotor to spin. Slight changes in the angle of the magnetic field caused the nanomotor to turn in desired directions.The researchers made several of the nanomotors in different sizes and tested them in different types of cells, some of which were from cancerous tumors. They report that the smallest (250-nanometer) nanomotors offered the most flexibility for movement inside of the cells. To prove just how well they could steer a nanomotor inside of a cell, the team directed one along a path that outlined the letters “M” and “N.” They acknowledge that their tiny motors are still in the early stages of development, but suggest their design is likely to lead to applications in drug delivery, or even nano-surgery. More information: Malay Pal et al. Maneuverability of Magnetic Nanomotors Inside Living Cells, Advanced Materials (2018). DOI: 10.1002/adma.201800429AbstractSpatiotemporally controlled active manipulation of external micro‐/nanoprobes inside living cells can lead to development of innovative biomedical technologies and inspire fundamental studies of various biophysical phenomena. Examples include gene silencing applications, real‐time mechanical mapping of the intracellular environment, studying cellular response to local stress, and many more. Here, for the first time, cellular internalization and subsequent intracellular manipulation of a system of helical nanomotors driven by small rotating magnetic fields with no adverse effect on the cellular viability are demonstrated. This remote method of fuelling and guidance limits the effect of mechanical transduction to cells containing external probes, in contrast to ultrasonically or chemically powered techniques that perturb the entire experimental volume. The investigation comprises three cell types, containing both cancerous and noncancerous types, and is aimed toward analyzing and engineering the motion of helical propellers through the crowded intracellular space. The studies provide evidence for the strong anisotropy, heterogeneity, and spatiotemporal variability of the cellular interior, and confirm the suitability of helical magnetic nanoprobes as a promising tool for future cellular investigations and applications.

6 min read Growing a business sometimes requires thinking outside the box. February 16, 2017 This story originally appeared on PCMag Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global When it comes to robot-human relations, the conversation typically centers on the welfare of the sentient. Science fiction paints us as petrified by our own creations; fears of a bot planet have influenced everything from Asimov’s “Laws of Robotics” to HAL 9000’s homicidal impulses to Skynet’s global genocide.These human-centric anxieties are understandable. However, as our assorted bots and bits gain skills and personalities, should they be afforded some form of protection from us? It’s a question people are starting to seriously ponder.Last month, the European Parliament’s legal affairs committee issued a report on the use and creation of robots and artificial intelligence (AI). It recommended creating a form of “electronic personhood” that would afford rights and responsibilities to the most advanced forms of AI.Many surely bristle at the concept of “rights” being awarded to software. While AI is increasingly capable of performing specific tasks, it’s not complex enough to have an opinion on how it is treated. It’s completely reasonable to ask if robo-rights is even a debate worth having right now. Indeed, humanity has far more immediate concerns on its plate (the humans of the European parliament in particular), but the era of personhood-worthy bots isn’t as far off into the crazy super future as you might think.While the human-like AI long promised by science fiction has thus far failed to materialize, researchers around the globe are hard at work turning it into reality. I don’t expect to see anything resembling Star Trek’s Data or Rosie from The Jetsons in the immediate future, but I wouldn’t be surprised to meet them in my lifetime: History has shown time and again that technology — particularly information technology — doesn’t just improve incrementally, it rockets forward exponentially. Consider some of modern AI’s very impressive feats and try to imagine what it will be able to accomplish in 10, 20 or 30 years.I can’t say for sure what robots or AI of the future will be able to do. But I can say that if robot ethics doesn’t rise to the level of a serious concern for society, then — at the very least — robot etiquette should.The AI among usThe average reasonably connected person in the developed world has probably interacted with modern AI in the form of increasingly capable chatbots or digital assistants (Alexa, Siri, Cortana etc.). But most AI remains hidden below the virtual surface.A sub-field of AI known as “machine learning” is particularly promising — this discipline is interested in creating algorithms that improve at tasks over time to come to original conclusions. There are even algorithms that are able to re-write their own source code in limited scenarios. Taken together, the most advanced algorithms could be said to form a unique identity.The question then becomes: Will we ever reach a point where this uniqueness rises to the level of being a personality worthy of protection? Few would argue that personhood should be awarded to, say, your smartphone’s OS. But your device (including all its the networked cloud resources) has a completely unique character unlike any other piece of software. Your phone remembers the Wi-Fi sources it routinely connects to, it learns your commuting habits based on GPS and even uses algorithms to learn the nuances of your voice commands (it’s how Siri and Google get better at understanding your voice over time).We can delete all or part of this data and not feel any emotional response. However, we will probably experience a deeper form of attachment if this data takes a physical, touchable form. Humans are inclined to relate to physical objects, no matter how “dumb” they are — people personify stuffed animals, name their cars or feel bad when their Roomba (one of the dumbest robots you can buy) gets stuck in a corner.While the gap between the robots we were promised and those we have is even more extreme than the one between promised and actual AI, the field is improving at a frighteningly rapid pace. This development is important to our discussion because it is far less emotionally taxing to “pull the plug” on a text-based chatbot, no matter how advanced, than it would be on a machine with a discernable face.It might be decades before technology forces us to truly confront the issue robot rights, but the debate surrounding the ethics of how we treat machines is probably worth having right now.Recently, I interviewed Dr. Kate Darling, a robot ethicist from MIT’s Media Lab as part of our streaming interview series and podcast, The Convo. While Darling isn’t quite on board with electronic personhood (at least not yet), she is interested in how humans interact with their technology and believes our choices are ultimately a reflection of us.”The one thing that does separate robots from other machines is that we tend to treat them like their alive,” explains Darling. “I think that there’s a Kantian philosophical argument to be made. So Kant’s argument for animal rights was always about us and not about the animals. Kant didn’t give a shit about animals. He thought ‘if we’re cruel to animals, that makes us cruel humans.’ And I think that applies to robots that are designed in a lifelike way and we treat like living things. We need to ask what does it do to us to be cruel to these things and from a very practical standpoint — and we don’t know the answer to this — but it might literally turn us into crueler humans if we get used to certain behaviors with these lifelike robots.”While science fiction has gotten a lot wrong in its predictions of what the robo-future would look like, it does provide a laboratory of the imagination. Would you rather live in, say, a Westworld universe filled with humans who feel free to rape and maim the park’s mechanical inhabitants, or on the deck of Star Trek: The Next Generation, where advanced robots are treated as equals? The humans of one world seem a lot more welcoming than the other, don’t they?So, when it comes to the question of how we interact with our creations, maybe we should be less concerned with determining their personhood than we are with defining our humanity.

It’s amazing how you can live close to something for such a long time, but never really see it. In my case, it’s the Bonnet Carré Spillway. It’s basically an overflow valve for the Mississippi River just upriver from New Orleans. When the river level gets dangerously high, the spillway is opened. This allows some of the river water to be diverted and instead of flowing downstream, it goes into Lake Pontchartrain. The spillway doesn’t open all that often, but this year it was opened twice, the first time in its history that that has happened.It’s kind of a big deal when they open up this spillway. Oh sure, I’ve seen the water rushing through the trees as I drive over it on the interstate—but that was about it. Well, until recently. I decided to make the trek down there with my younger son. It was fun. Now I can check this spillway off my “to do” list.But wait! This is a great opportunity for some real-world physics homework and estimation problems. Don’t worry. I’m going to get you started. I’ll give you some basic data on the spillway and then do two estimations for you. After that, you are on your own. Actually, I will start off with this video showing the spillway. It’s not perfect, but this is from our trip to the spillway—also, you can see what this thing looks like.[embedded content]Oh, you can even see a jumping asian carp in this short clip. From that video, you could get a rough estimate of the flow rate—but I’m going to give it to you anyway along with some other important facts. Rhett AllainNotice the fraction of 3600 seconds divided by 1 hour? Since 3600 seconds is equal to 1 hour, this fraction is just 1. If you multiply any number by one, you get the same thing. This is important. Although the numerical value will change, the actual value doesn’t change. It’s just a different number in different units, but the same actual amount. That’s the key to unit conversions.In order to calculate the rainfall in Ohio, it’s just one more unit conversion. What if I convert volume units from cubic feet to inches per Ohio? Yes, I can do that by multiplying by “1” again. I’m not going to write the whole thing out, I’m just going to list my conversions.1 Ohio = 208×230 square miles (approximately).1 mile = 5280 feet. Note, you have to do this conversion twice to go from square miles to square feet.12 inches = 1 foot.This gives a rain rate of 0.067 Ohio-inches per day. Yes, Ohio-inches is a unit of volume. If you convert the time part to months (assume 28 days), this would be 1.87 Ohio-inches per month. That seems fair. Oh! But remember that much of the rain that falls in Ohio wouldn’t make it to Louisiana. Some of it would evaporate, some goes into the ground, and some gets used by humans. I don’t know the percent of rain that makes it to the river, so I will just leave my answer alone. The spillway is 7000 feet long (2134 meters for non-Imperials).There are 350 “bays” that can be opened with each bay 20 feet wide (6.1 meters).The maximum flow capacity is 250,000 cubic feet per second of water flow (you can convert this to m3/s as a homework question).The floodway (the part of land that becomes a temporary river) is 5.7 miles long. At the Mississippi river side, the floodway is 7700 feet wide. When it gets to Lake Pontchartrain, the floodway is 12,400 feet wide.Finally, here is a nice table that shows the number of spillway bays open on different days. For the video above (when I visited), there were 138 bays open.How much power could you get from the spillway?Suppose this spillway was some type of hydroelectric generator? How much power could you get from it? Let me start with the physics. If you take some water with a mass of m and drop it a height h, it will have a change in gravitational potential energy. This change in energy can be expressed as:Rhett AllainIn this expression, g is the local gravitational field with a value of about 9.8 Newtons per kilogram. If you just drop some water, this change in gravitational potential energy will make the water increase in speed to give it an equal amount of change in kinetic energy. However, if you have some type of generator you can use this energy to power stuff—like your phone or some other electric device. But what about the power? Power is a measure of how quickly something produces energy. That means it not only depends on energy, but also time. Here is an expression for the power.Rhett AllainNow let’s say that this water is pouring over the spillway at a flow rate of f in cubic meters per second (yes, the spillway page gives this in cubic feet per second). With the density of water (ρ), I can find the mass of water falling per second as ρf. Using this with the change in gravitational energy and the definition of power, I get:Rhett AllainWait! What is that e? I added that in there—it’s the efficiency. Surely you don’t think that all of the energy from that falling water will go into useful stuff, do you? Let’s say that this hydroelectric generator is just 25 percent efficient (so e = 0.25). That can account for the amount of water that doesn’t pass through the generator as well as the energy lost in the power conversion process. I’ll put all these values together in a python calculator (that way you can change the values and re-run it). Here is the result (just click the pencil icon to edit the code).[embedded content]With my estimates, that’s a power output of 11.9 megawatts. Just for comparison, most nuclear power plants produce at least 100 times more power than this spillway generator. Oh, and it will probably be open for about a month. But it’s still a fun estimate.How much rain is in this spillway?Just to be clear, the spillway is open because of rain and snow melt (but mostly rain in this case). It rains somewhere in the Mississippi river basin (which is huge) and some of this rain water ends up in Louisiana. So, the real question. Suppose it rains in Ohio. How much rain would need to fall on the whole state in one day such that you get the current flow rate at the spillway (86,000 cubic feet per second)?At first pass, this is a flow rate problem. Imagine this: A bunch of water enters Ohio and then leaves through the spillway. What’s the difference between the entry and exit? The cross-sectional area is the difference. In Ohio, this area is the size of the whole state. So, let’s approach this problem from the backend. I already know the flow rate at the spillway. I can use this to calculate the total volume of water that passes in one day. This volume of water will then be spread over the state of Ohio to calculate the rainfall.Step one is to convert the flow rate in units of cubic feet per second to cubic feet per day. Yes, I’m using imperial units—but only because I’m dealing with a state in the US. I would do the same for the only other two imperial unit countries: Liberia and Myanmar. So, this is really just a unit conversion problem. The key to unit conversions is to just multiply by the fraction (1/1). Here, let me show you. HomeworkNow it’s your turn. Here are some questions for you to consider.If the spillway is fully open (all bays open), what percent of the Mississippi river would be diverted through the spillway? Yes, you will either need to estimate the flow rate of the Mississippi, or look it up.Suppose Lake Pontchartrain was completely empty. How long would it take to fill up the lake using just the Bonnet Carré spillway?How deep is the floodway? Hint: use the dimensions of the spillway along with the flow rate.

Glitch, the web apps creating tool, has made a series of major announcements yesterday. Glitch is a tool that lets you code full-stack apps right in the browser, where they’re instantly deployed. Glitch, formerly known as Fog Creek Software, is an online community where people can upload projects and enable others to remix them. Creating web apps with Glitch is as easy as working on Google Docs. The Glitch community reached a milestone by hitting 2.5 million free and open apps, more than the number in Apple’s app store. Many apps on Glitch are decidedly smaller, simpler, and quicker to make on average focused on single-use things. Since all apps are open source, others can then remix the projects into their own creations. Glitch raises $30M with a vision of being a healthy, responsible company Glitch has raised $30M in a Series A round funding from a single investor, Tiger Global. The round closed in November 2018, but Anil Dash, CEO of Glitch said he wanted to be able to show people that the company did what it said it would do, before disclosing the funding to the public; the company has grown twice in size since. Glitch is not your usual tech startup. The policies, culture, and creative freedom offered are unique. Their motto is to be a simple tool for creating web apps for people and teams of all skill levels, while fostering a friendly and creative community and a different kind of company aiming to set the standard for thoughtful and ethical practices in tech. The company is on track for building one of the friendliest, most inclusive, and welcoming social platforms on the internet. They’re built with sustainability in mind, are independent, privately held, and transparent and open in business model and processes. They are building a healthy, responsible company and have shared their inclusion statistics, and benefits like salary transparency, paid climate leave (consists upto 5 consecutive work days taken at employee’s discretion, for extreme weather), full parental leave and more in a public handbook. This handbook is open-sourced so anyone, anytime, anywhere can see how the company runs day to day. Because this handbook is made in Glitch, users can remix it to get their own copy that is customizable. As the community and the company have grown, they have also invested significantly in diversity, inclusion, and tech ethics. On the gender perspective, 47% of the company identifies as cisgender women, 40% identify as cisgender men, 9% identify as non-binary/gender non-conforming/questioning and 4% did not disclose. On the race and ethnicity front, the company is 65% white, 7% Asian, 11% black, 4% Latinx, 11% two or more races and 2% did not disclose. Meanwhile, 29% of the company identifies as queer and 11% of people reported having a disability. Their social platform, Anil notes has no wide-scale abuse, systematic misinformation, or surveillance-based advertising. The company wants to, “prove that a group of people can still create a healthy community, a successful business, and have a meaningful impact on society, all while being ethically sound.” A lot of credit for Glitch and it’s inclusion policies goes to Anil Dash, the CEO. As pointed by Kimberly Bryant, who is the founder of BlackGirlsCode, “’A big reason for Glitch’s success and vision though is Anil. This “inclusion mindset” starts at the top and I think that is evidenced by the companies and founders who get it right.” Karla Monterroso, CEO Code2040 says, “It becomes about operationalizing strategy. About creating actual inclusion. About how you intentionally build a diverse team and an org that is just.” Dash notes, “It’s the entire team working together. Buy-in at every level of the organization, people being brave enough to be vulnerable, all doing the hard work of self-reflection & not being defensive. And knowing we’re only getting started.” Other community members and tech experts have also appreciated Dash’s resilience into building an open source, sustainable, inclusive platform. People have also used it for activist purposes and highly recommend it. Glitch now on VSCode offering real-time code collab Glitch is also available in Visual Studio Code allowing everyone from beginners to experts to code. Features include real-time collaboration, code rewind, and live previews. This feature is available in preview; users can download the Glitch VS Code extension on the Visual Studio Marketplace. Features include: Rewind: look back through code history, rollback changes, and see files as they were in the past with a diff. Console: Open the console and run commands directly on Glitch container. Logs: See output in logs just like on Glitch. Debugger: make use of the built-in Node debugger to inspect full-stack code. Source: Medium For now the company is dedicated solely to building out Glitch and release specialized and powerful features for businesses later this year.

While our phones are running low on battery, we do not think twice before inserting a USB to charge it. Also, while transferring files to and fro other devices, we consider the simple wire as benign. Recently, in a demonstration at DefCon 27, a hacker by the online handle MG infected a simple iPhone USB lightning cable with “a small Wi-Fi-enabled implant, which, when plugged into a computer, lets a nearby hacker run commands as if they were sitting in front of the screen”, TechCrunch reports. Per Motherboard, MG made these cables by hand, painstakingly modifying real Apple cables to include the implant. MG told Motherboard, “It looks like a legitimate cable and works just like one. Not even your computer will notice a difference. Until I, as an attacker, wirelessly take control of the cable.” These dummy cables named as “O.MG cables” are visually indistinguishable from the original cables. They also work similar to an original piece, allowing users to charge their devices via USB or transfer files from their iOS devices. The hacker not only showcased the infected cable at DefCon but has also put these similar cables on sale for $200. “There has been a lot of interest and support behind this project,” MG says on his blog, “and lots of requests on how to acquire a cable. That’s a great feeling!” Once the cable is plugged into a device, it enables an attacker to mount a wireless hijack of the computer. “Once plugged in, an attacker can remotely control the affected computer to send realistic-looking phishing pages to a victim’s screen, or remotely lock a computer screen to collect the user’s password when they log back in,” TechCrunch writes. “In the test with Motherboard, MG connected his phone to a wifi hotspot emanating out of the malicious cable in order to start messing with the target Mac itself. MG typed in the IP address of the fake cable on his own phone’s browser and was presented with a list of options, such as opening a terminal on my Mac. From here, a hacker can run all sorts of tools on the victim’s computer”, Motherboard’s Joseph Cox writes. On being asked how close an attacker should be plugged in device, MG said, “I’m currently seeing up to 300 feet with a smartphone when connecting directly.” “A hacker could use a stronger antenna to reach further if necessary. But the cable can be configured to act as a client to a nearby wireless network. And if that wireless network has an internet connection, the distance basically becomes unlimited.” he added. Now MG wants to get the cables produced as a legitimate security tool; he said the company Hak5 is onboard with making that happen. These cables would be made from scratch rather than modified Apple ones, according to Motherboard. MG said, “Apple cables are simply the most difficult to do this to, so if I can successfully implant one of these, then I can usually do it to other cables.” How can one avoid getting tricked by the dummy USB lightning cables? Users should ensure they do not go by the looks of the external packaging if any random cable is simply lying around. One should also avoid accepting unsolicited chargers, USB dongles, or similar components as gifts from people they do not trust. Also, one should avoid borrowing chargers from people they do not know. While purchasing any tech component, users should choose from legit sources online or from any physical ensured locations where the packaging hasn’t been tampered with. While out in public places, one should always ensure their devices, cables, USB dongles, and other components are nearby and secure. A user on HackerNews is infuriated over why major vendors like Windows, macOS, and Linux have not implemented these basic precautions “It’s a severe discredit to the major operating system vendors that plugging in a USB stick can still compromise a system.” The user further adds, “If a USB device identifies itself as a keyboard, the system shouldn’t accept its keystrokes until either that keyboard has typed the user’s login password, or the user uses a different input device to authorize it. If it identifies itself as a storage device, the filesystem driver should be hardened. If it identifies itself as an obscure 90s printer with a buggy driver written in C, it should prompt the user to confirm the device type before it loads the driver.”Another user on HackerNews wondered how one could ensure the cables sold online are legitimate; he writes, “Even more frightening, people selling them as seemingly legitimate cables on Amazon? People will pay you and you get a new botnet. How many could you sell before it’s discovered? How can I, as a consumer, even tell? Amazon will even allow you to sell your malcable under the Apple brand.” To know more about this news in detail, head over to Motherboard complete report.

Go back to the e-newsletter >Havana, CubaWith the opening of relations between the US and Cuba, the colourful Cuban culture of Havana is going to be at the top of everyone’s bucket lists (accommodation for 2016 already selling out!). Sales to Cuba tripled during 2015 as travellers rush to see the Caribbean Island before the hordes arrive. Discussions are underway for allowing regularly scheduled flights between the two countries and Mastercard has already partnered with a Florida bank to make ATM transactions work in Cuba.

The forecast comes as global relations improve with the Middle Eastern country, meaning Iran’s Islamic architecture, uncrowded beaches and traditional Persian cuisine will likely top the list of next years must see destinations.Photo credit: Golden Eagle Luxury TrainsMumbai, IndiaWith India’s economy expecting to keep booming in 2016, it only makes sense that the country’s powerhouse of finance, film, food and festivals will see a lift in tourism. The ‘Maximum City’ is being smart with its buck, investing its money in ways that will boost its travel sector; the airport has a new terminal, an air-conditioned monorail is now ready to ride, and next year the world’s tallest residential building will be unveiled.
