When Microsoft announced its newest operating system, the surprise was not that it was coming, but that Windows would be skipping 9 and headed straight to 10. When asked about Windows 10’s name, Microsoft didn’t give a clear answer. So why, exactly, is Windows 10 getting the nod instead of 9?

Version numbers, version schmumbers

First of all, it’s important to note that between Windows 3 and Windows 7, versions of Windows were designated by a name rather than a number: 95, 98, NT, Me, 2000, Vista, and so on. When Microsoft announced Windows 7, there was actually a similar amount of disbelief; after a series of named versions of Windows, it seemed odd to jump back to numbers.


There’s also the fact that the name of each Windows release doesn’t actually match the real version number; for example, Windows 8.1 is actually version 6.3 of Windows. Windows 10 is version 6.4. The last time the release name actually matched the version number was Windows NT 4.0, which was released back in 1996. Windows 2000, which was called NT 5.0 during development, was actually version 5.0. Windows XP was version 5.1. Windows Vista was 6.0, Windows 7 was 6.1, Windows 8 was 6.2, and Windows 8.1 is version 6.3. (WinRT, which powers Metro, is a new and separate beast, but it still sits on top of the core Windows kernel.)

Technically, modern versions of Windows are still based on the Vista kernel and code base — including Windows 10, which is actually Windows 6.4. There will be some confusion if (or when) we eventually reach internal version 7.0, but we’ll cross that bridge when we get there.

Alternative theories for skipping Windows 9

First, an ExtremeTech reader called Benny sent an email to say that the number 9 is considered unlucky in Japan. Microsoft has a big enough presence in Japan that it may have skipped Windows 9 to avoid any weirdness or ill will. Benny says that Trend Micro — a Japanese company — did the same thing a few years ago when it skipped version 9 of its antivirus software.

Second, someone purporting to be a Microsoft developer posted this comment on Reddit:
As stupid and amazing as this sounds, it is actually quite feasible that there are still a lot of legacy Desktop apps that use this method (or something similar) to check for Windows 95 or 98. Bear in mind that this is just an example piece of code — some developers will check for the OS name (“Windows…”), some will check for the version number (as discussed in the previous section of this story), and some might use other methods entirely to find out what OS the app is running on.


What’s in a name?

Ultimately, Windows 10 is just a name. Windows 9 probably would’ve made more sense — and I think it’s going to cause a lot of grief with novice users who just don’t understand what happened to Windows 9 — but Windows 10 isn’t any more right or wrong than calling Vista’s successor Windows 7.


A better question to ask now, though, is: Why did Microsoft call it Windows 10 specifically, and not something else? During the unveil event (video embedded above) Myerson gives us a few clues. Starting at around the 2:10 mark, he says: “We know, based on the product that’s coming, and just how different our approach will be overall, it wouldn’t be right to call it Windows 9.” He then talks about how Windows One would make sense with Xbox One, OneDrive, and OneNote, “but unfortunately Windows 1 has been done by the giants that came before us.” And so it seems the only other viable option was Windows 10.


Microsoft’s seemingly arbitrary naming convention of “Windows 10″ is an interesting one. It is clearly a strong version number — and it’s also a neat way of distancing it from Windows 8, which Microsoft really wants to brush under the carpet. In fact, this might even be the same trick that Microsoft used to make us forget about Vista: “With a name like Windows 7, it must be very different from Vista.”

 
What about any similarity to Apple’s Mac OS X? Apple did a similar trick: Its operating systems steadily incremented through System 1-7, then switched to Mac OS 8 and 9, and when it got to OS 10 (X) in 2001 it stopped. Given how Windows 10 is meant to be a single platform for just about every form factor, plus the massive weight and importance that Microsoft is lending to this release, I wouldn’t be surprised if it sticks around for a long time. I wouldn’t be surprised if future versions of Windows — at least for the next few years — are 10, 10.1, 10.2, 10.3, etc. I don’t think Microsoft is intentionally aping Apple with Windows 10, but I’m sure the marketing department is aware of both the positive and negative repercussions of wanting to ride on Apple’s coattails.

So, there you have it: Windows 10 is called Windows 10 because Microsoft says so — even if “Windows” or “Windows X” would’ve been better. If you want to give Windows 10 a spin before its release, you can follow our guide and install the technical preview.








As battery technologies go, the world has a love-hate relationship with lithium-ion. On the one hand, breakthroughs in Li-ion designs and construction are responsible for the Tesla Model S, new installations, green energy research, and the modern smartphone. On the other hand, lithium-ion limitations are the reason why most EVs have a range of 40-60 miles, the Model S costs upwards of $80,000, and why your smartphone can’t last all day on a single charge. For all its promise and capability, lithium-ion has limited long-term utility — which is why a new announcement from Fuji Pigment is so interesting. The company is claiming that its new aluminum-air batteries can run for up to two weeks and be refilled with normal water.

How an aluminum-air battery works

First, some basics. The problem with battery technology isn’t whether or not we can build better batteries — as the chart below shows, we can build batteries that blow traditional lithium-ion out of the water. Keep in mind that the chart below is exponential, meaning that fuel cell technology has 10 times the energy density of a typical cobalt-Li ion battery.


The various “Metal-Air” batteries, including zinc-air, aluminum-air, and lithium-air, have some of the highest energy densities its possible to build. The difficulties with aluminum-air construction, in particular, has been rapid degradation of the anode and, in early models of Al-Air, the release of hydrogen gas.
Fuji Pigment’s new announcement makes repeated reference to the work of Ryohei Mori, and while the referenced papers aren’t available for free, the abstracts are online. The studies in question are all aimed at enhancing the performance of Al-air batteries while extending their useful lifetimes — typically, Al-air solutions begin to degrade immediately after the first charge cycle. According to Mori’s work, creating a secondary aluminum-air battery adjacent to the primary buffered the accumulation of byproducts that normally prevent the battery from working properly over the long term.
The “rechargability” of Al-air batteries requires some explanation. Al-air batteries are primary cells, which means they can’t be recharged via conventional means. As the aluminum anode is consumed by contact with oxygen, hydrated aluminum forms as a byproduct. That material can be recycled and used to create a new aluminum anode, which is why the batteries are referred to as rechargeable. Periodically, the aluminum anode will have to be replaced — it’s not clear how often the Fuji Pigment battery would need servicing of this sort.

Could Al-air be the next big thing?

New battery technologies and announcements are a dime a dozen, but there’s reason to think that a workable Al-air technology could deploy within the next 2-5 years. Multiple manufacturers are working on commercializing designs (Alcoa partnered with Phinergy in 2013 with plans for a 2017 debut), and aluminum is abundant and relatively cheap. Al-air batteries have actually been used in specialized military applications for years, which is important — it means there’s some pre-existing expertise and known characteristics that can be leveraged to create additional capacity.
That said, there are question, too. The hydrated aluminum oxide solution produced during the battery’s normal operation would need to be recycled in some fashion, it’s not clear that fresh water is as effective an aqueous solution as saltwater (meaning there might be specific need for one particular kind of solution). The final price is also unknown, though previous estimations had put the cost of an Al-air system at roughly $1.1 per kg of aluminum anode. This was not given in precise terms relative to the cost of gasoline (and the weight of the aluminum anode in these batteries is unknown), but the team that performed that analysis noted that proper recycling would put Al-air in the same cost range as conventional internal combustion engines.
Fuji Pigment has stated that it intends to commercialize this technology as early as this year, which means we could see test demonstrations and proof of concepts by 2016. Whether auto manufacturers will jump for the technology remains to be seen — car companies tend to be conservative and Tesla has already thrown its weight behind the further use of lithium-ion technology.

Engineers have been struggling for years to develop some new breakthrough idea that will push battery technology to the next level. Instead, we’ve been stuck with iterative improvements that limit the power and usefulness of our mobile devices. Perhaps batteries aren’t the right way to go at all, though. A doctoral researcher at Aalto University in Finland has developed a prototype of a highly efficient micro fuel cell that runs on alcohol. Maybe in the future when you swing by the bar for a drink, you’ll also be able to top off your phone.

We’re used to hearing about fuel cell technology in motor vehicles, but at the most basic level, fuel cells are simply a way to generate electricity. There’s no reason a fuel cell cant work in a mobile device, and the high energy density would make it potentially far superior to a lithium-ion battery. It’s just a matter of making the cell small and durable enough to ride around in a smartphone in your pocket all day.

The Aalto University fuel cell was designed by Gianmario Scotti for his doctoral dissertation. Like larger fuel cells, the micro cell consumes alcohol and oxygen, outputting water, carbon dioxide, and of course, electricity. It’s able to run on either methanol or ethanol, but the latter is preferable. Not only is ethanol easier to produce with our current energy infrastructure, it comes with minimal health hazards (this is the alcohol we can consume safely in moderation). Methanol, by contrast, is highly toxic when ingested, and is also a skin irritant.


 The cell designed by Scotti is a tiny aluminum wafer just 14 mm2 and less than a millimeter thick. Using a picosecond laser allowed Scotti to fabricate the cell using aluminum rather than the more common silicon, which helped to reduce the cost and weight. Despite its small size, supplying it with alcohol outputs 0.5 volts — hydrogen can produce a full volt, but is far less practical. A few of these cells wired up in series would provide enough juice to keep your phone running. Then it’s just matter of keeping the reservoir supplied with reactants.



Scotti discusses in his dissertation the best way to refill a micro fuel cell like the one he’s designed. The system would need to be kept clean, so you wouldn’t just pop it open and pour some ethanol in. A pump or capillary action could be used to recharge the cell, but either method would be much faster than plugging a battery into the wall. Air (oxygen) is required for the reaction, so air quality might be more troublesome than the alcohol component. In regions with high particulate levels in the atmosphere, the fuel cell could become clogged and fail to function. So taking your micro fuel cell phone to Beijing might leave you without power, and no amount of booze is going to fix it.

Powering smartphones is really just the most consumer-facing use for micro fuel cells. Scotti suggests that these same devices could be of use with micro-satellites, which need to keep weight down for launch and only remain in orbit for a limited time. As for when these power sources might find their way into mobile devices, Scotti says it could be anywhere from 1-10 years. Until then, you’ll just have to fill yourself with alcohol instead of your phone.

Even the largest external battery packs will only free you from the grid for so long before you need to plug in and recharge. Kraftwerk isn’t just another battery, even though it might look like one. This tiny 200g device is actually a self-contained fuel cell that runs on standard lighter gas and can charge an iPhone 11 times with just a tiny puff. After opening a Kickstarter campaign in early January, Kraftwerk has almost doubled its $500,000 goal.

Hardware Kickstarters are always a little more worrisome than those for software or services. A lot of things can go wrong in the manufacturing process as a project comes together, but the engineers at eZelleron have already developed the technology and have a working prototype to show off. It only takes three seconds to fill the reservoir in the Kraftwerk, which is much faster than charging a giant lithium-ion battery, but why go back to hydrocarbons?
 


For all the disadvantages hydrocarbons have, they come with extraordinary energy density. That’s why the cost of renewable energy still hasn’t caught up to good old-fashioned internal combustion. Of course, Kraftwerk is a fuel cell, so it’s not actually burning the lighter gas (sometimes called camping gas LPG fuel). Instead, it’s using a chemical reaction inside the fuel cell to harvest the hydrogen atoms from butane generate power. eZelleron is fond of calling this a personal power plant, which might be grandiose, but not necessarily wrong.
From what the company is saying about the process, Kraftwerk sounds like a very small, efficient solid oxide fuel cell (SOFC). The reaction of hydrocarbons (in the form of butane) and oxygen inside the fuel cell gives you power (and a tiny bit of heat), but the exhaust from this system isn’t bad. It’s just water vapor and carbon dioxide, not unlike the exhaust coming from you. It’s apparently also safe to take on an airplane. If the carbon output bothers you, there are eco-friendly LPG fuels available that are made from renewable sources.
You can charge anything that connects over USB with the Kraftwerk, but it only has the one port. That’s probably because the sustained power output is just 2 watts, with peak power of 10 watts. That’s enough to charge a phone or tablet, but some newer devices can accept up to 15 watts with Qualcomm Quick Charge enabled. Capacity is hard to measure compared to lithium-ion cells, but a full tank in the Kraftwerk should give you the equivalent of roughly 20,000mAh. However, you won’t lose anything to lithium-ion inefficiency as you would with a battery.






The Kraftwerk still has a month to go, but it’s closing in on $1 million. This is going to be a big one — all of the early bird deals are gone, so you’re looking at $99 for a single Kraftwerk. It’s pricey, but you can get a lot of efficient power from it — a single can of $5 lighter gas can refill the Kraftwerk a few dozen times. If you jump on this, eZelleron expects to start shipping final units in December 2015. Check out the Kickstarter video below:

2. File Manager:

Android’s visible file system gives more control over data in your smartphone. You create folders, drag and drop them on computer. The open file system makes it as efficient as using the file system on computer. Apple doesn't give access to file system on iOS.

3. Customisation:


Android has multiple customisation offerings. You get wide range of widgets, themes and launcher. iPhone on the other hand has very limited customization options, user just gets to customize parallax effect and dynamic wallpapers.

4. Integrated Apps:

Android gives wide API access to the developers. So developers built applications that are highly integrated with the OS. Sharing the content across apps is more seamless in Android as compared to iPhone. However, in iOS8, iPhone has introduced Extensibility that makes this integration possible.

5. Image Management:

Android has better image management system. It automatically sorts and puts screenshots, downloaded photos and pictures in separate folders. This is very clustered in iPhone. iPhone puts everything in camera roll.

6. Notifications:

You get informative icons of notifications on top of notification bar, it is filled with icons, which gives reminder of what you have received. In iOS, there are no such icons. You have to pull down the notification bar every time to check for notifications.

7. Lockscreen:

Android provides multiple screen locking options. You can personalise the locking of screen in Android. It features pattern lock, pin lock, facial recognition. While, iPhone has just pin lock; only latest iPhones feature the fingerprint scanner.

8. Gmail:

The default mailing app on Android is much more user friendly and real-time in Android. The latest Inbox is quite revolutionary. In iOS, the mailing app lacks many basic features. If an email consists a phone number, you cannot even dial it on iPhone.

9. Google Keep:

Google Keep is the best note taking app. It is limited to Android only. The best part is, notes stay synced with Google Drive. You can use the unofficial ‘GoKeep’ app for iPhone to access Keep on iOS.

10. External Storage:

External storage comes very handy in case of sharing. Most Android phones feature microSD support. You can expand your storage to any limit with Android. Whereas on iPhone, you have to compromise with limited internal storage that you get.

How a 7-year Betsy Davies hacked a public Wi-Fi network in less than 10 minutes

Millions of people use free Wi-Fi services at the local coffee shop, Airports or designated Wi-Fi hotspots where they work, make a video call or simply shop online. But public Wi-Fi networks have a pretty bad security record  and this is what VPN provider www.hidemyass.com wanted to prove. 

An ethical hacking experiment was conducted as part of a new Wi-Fi safety public awareness campaign by VPN provider hidemyass which aims to prove that how easily one can hack into computers which are connected to these free public Wi-Fi hotspots.

The aim of hidemyass was public awareness but what 7 year old Betsy Davies did was more surprising. Betsy Davies from Dulwich in South London hacked a willing participant’s laptop while it was connected to an open Wi-Fi network in less than 10 minutes.
The Experiment

Hidemyass obtained the consent of her family as she is a minor and set up a controlled environment for Betsy to work.  They build a purpose-made open Wi-Fi network which was similar to any of the public Wi-Fi networks found every where.


similar to any of the public Wi-Fi networks found every where.

It took Betsy just 10 minutes and 54 seconds to learn how to set up a rogue access point, frequently used by attackers to activate what is known as a ‘man in the middle’ (MiTm) attack.  After setting up a rogue access point, Betsy managed to eavesdrop on the willing participants (victim’s) internet traffic.

More worry is that the 7 year old primary schooler used the hacking instructions available extensively online through Google Search engine.  If a 7 year old can take less than 11 minutes to hack into a computer through a Public Wi-Fi hotspot, just imagine how easily a hardened cyber criminal can break into any computer that is connected to such public Wi-Fi systems.

Though the idea behind this in-lab experiment was to show how insecure the public Wi-Fi networks are, users should note that this in-lab experiment is being replicated by thousands of cyber criminals in the open.  So just be that extra careful if you are on a public Wi-Fi network.

About a year after the announcement of plans of addition of voice calling plans, WhatsApp is probably rolling out the feature in India. Last night, a Reddit user uploaded images and videos of the voice calling feature being rolled out to the devices. Right now, this feature is reportedly limited to the very few users. WhatsApp announced the plans of voice calling in February of 2014. Later it was said that the company is working to make this feature run seamlessly on slow networks.

According to Reddit user pradnesh07, this feature has appeared on his phone and using Nexus 5 running on android 5.0.


How you can get voice-calling on WhatsApp right now?

According to the user, just updating the WhatsApp won’t enable this feature. It’s like an invite thing. A person who has got this feature, needs to make a call to another person. He wrote: “Its like an invite thing, where a person with the call feature needs to “call” another person who wants to start using the feature. You need to get the apk from the website and not from the PlayStore.”

See the pictures below:







He further writes:

“The guy who sent me the invite confirmed that it works on other phones on other roms and other OS and in other countries. I am not sure how the invite thing works as of yet. I made a quick video of how the call works and looks so that you guys can share. And there is no use asking me for invites right now, I don’t know how this invite thing works exactly.”

I have written a lot in the past about Oculus Rift and how it has the potential to revolutionize gaming industry. Yesterday, I came across this system called RoomAlive on New Scientist, which is being hailed as the next big thing in gaming.

RoomAlive is developed by Microsoft.







What is RoomAlive?

RoomAlive is capable of transforming any room into a giant playing arena. It is an extension of Microsoft’s previous IllumiRoom research project. It uses and combines Kinect and projectors to create a unique augmented reality experience in a room. You can interact with the objects and play it. It uses six Kinect depth cameras for depth sensing.


How RoomAlive projects things?

The basic unit of RoomAlive is called a node. A node consists of a projector, a Kinect camera and a computer. The node is fitted on the ceiling and it creates a 3D projection in the room. Microsoft research has used around three such nodes to cover an average sized living room.



How it engages the player?

RoomAlive tracks your position continuously in the real time. Anytime you touch a surface, it responds and acts like a touchscreen. This is possible because the projectors are knowing your positions. It uses parallax technology i.e. using 2D projections to look like 3D projections. Microsoft has also enabled a technology named Mano-a-mano i.e. two people can enjoy a unique perspective in the same room.


What games are available right now on RoomAlive?
Games developed for RoomAlive include Whack-A-Mole. In this game, players have to use an infrared gun to bust moles which appear all around the room. Another game includes a robot fighting game played with an ordinary Xbox controller.

A  Microsoft Research spokesperson says :
“There’s still lots to explore with RoomAlive as a gaming platform, we envision a future where games can use physical objects as part of the game.”

After buying Oculus Rift for $2 billion in form of cash, stocks etc., Facebook is now eyeing to make money from the investment. Facebook is now in talks with Hollywood studios about making feature films especially for Oculus Rift according to The Information.







Oculus Rift was initially focused on gamers but it seems that Hollywood too is interested in it.
Legendary pictures has recently entered into some agreement, thanks to its Pacific Rim Franchise. At the 2014 San Diego Comic-Con Legendary Pictures allowed you to pilot a Jaeger from its Pacific Rim franchise, and Fox included the Oculus Rift to let you experience Cerebro from their X-Men movies.


Well, Facebook has still not made any announcements regarding any specific time when Oculus Rift will be launched for the consumers.




In the past we have seen that Facebook is very much concerned about better protection of its own servers and customers and is even more worried about the same in the wake of what security researchers have called one of the biggest security breaches in the history of the Internet. A group of Russian hackers reportedly stole more than 1.2 billion passwords, according to the firm that conducted the 18-month long investigation that uncovered the breach.


To tighten its security they recently bought a Palo Alto-based secure server technology company PrivateCore this morning. Terms of deal were enclosed but some news agencies reported that a funding of $2.2 millions raised by the company.
Facebook’s Chief Security Officer, Joe Sullivan told more that the value of a company like PrivateCore to Facebook, as part of the company’s focus on increased security. Facebook has been ramping up its rollout of HTTPS encryption by default, and is also working to secure all its data centers with additional protections.
Sullivan told, “Their vCage technology protects servers from persistent malware, unauthorized physical access, and malicious hardware devices, making it safer to run any application in outsourced, hosted or cloud environments.” He added, “I believe that PrivateCore’s technology and expertise will help support Facebook’s mission to help make the world more open and connected, in a secure and trusted way.”
“Working together with Facebook, there is a huge opportunity to pursue our joint vision at scale with incredible impact,” said PrivateCore CEO Oded Horovitz in a press release.
