Good Bye Wi-Fi Sense!

Microsoft has finally disabled its controversial Wi-Fi Sense in Windows 10. The feature allowed people to share access to Internet with their Skype and Outlook contacts. In fact, a recent update allows people to share access to their Wi-Fi networks even with their Facebook friends, if so they desire.

According to Microsoft, the feature was removed because it was too expensive to maintain, and it was only used by a small number of people. It may be true, but the reality is that most people were terrified by the possibility of enabling it accidentally.

Wi-Fi Sense wasn’t actually sharing your Wi-Fi password with your contacts, but an encrypted version of it. On the other hand, people have easily managed to decrypt such passwords, and sometimes they even managed to do that using regular smartphones.

From now on, Wi-Fi Sense will only connect to open Wi-Fi hotspots that it knows about through crowdsourcing. It’s a late move indeed, but it’s a good one for all of us. Better late than never!

Can Google’s Routers Outsmart the Competition?

They surely can! At least that’s what the search engine giant officials tell us. Google has recently integrated IFTTT (If This Then That) capabilities into their OnHub routers.

I know, I know… you can’t keep up with all the technology info and news, but IFTTT has been around for quite some time now! It allows people to create (or borrow) “recipes”, series of instructions that tell certain web services to do something when a particular event takes place.

Want a real life example? How about automatically storing each picture that’s tagged with “family” into your Dropbox account, as soon as you take it? Or receiving an email when your kids log into Facebook? Well, they may not like that, but it’s entirely possible with IFTTT.

Now, all this power is available within Google’s routers as well. I’m pretty sure that other router manufacturers will soon ride this wave, helping us automate lots of boring tasks.

Wave 2 Wi-Fi Brings in Significant Internet Speed Increases

I know what you are thinking when you hear about home routers: cheap devices operating at low speeds. That’s why MIMO was invented, after all! But Linksys has come up with a new technology, intelligently named MU-MIMO (multiple users, multiple inputs, multiple outputs) and it’s already implemented it into its Linksys EA-7500 home/small business router.

It’s the first router that supports the Wave 2 technology – just a marketing gimmick, I know, but early tests show that the technology behind it is really impressive.

Geeky people have used directional +9dbi antennas and RP-SMA extension cables to extend their routers’ range until now, and it looks like beamforming, a much more efficient way of using the router radios, is the next logical step in the process.

So what’s so special this Wave 2 technology? Think about radio waves for a moment: they are emitted in every direction, just like the way a standard lightbulb works. With beamforming, the connected Wi-Fi devices exchange location information, and then the radios adapt their phase and power, optimizing signal strength.

This leads to lower power consumption and higher signal ranges. Early tests show a consistent 200-250% speed increase when it comes to downloads. Yes, beamforming is that good.

And the good news doesn’t stop here! Most modern devices (think 2014 or newer) are already able to make use of beamforming. All you need is a router that supports the new technology.

Sony has recently launched a consumer grade camcorder which is able to reproduce four times more details in comparison with most high definition cameras that are available on the market.

The new Handycam FDR AX1 can record movies using the fairly new 4k Ultra HD standard. It is true that 3D television didn’t catch up, but since more and more 4k TV sets are sold, this camera will surely find its market. If you’ve been disconnected from the IT industry during the last few years, you may not know that a 4k image has a 3,840 x 2,160 pixels resolution, storing four times more details in comparison with the actual full HD images. For high end photographers and videographers, this means more details and, as a consequence, much better images. The price is fairly decent at a 4,000 USD and I am pretty sure that it will become lower as the competition catches up.

Here’s an actual recording made with the Handycam FDR AX1. Don’t forget to choose the 2,160p resolution. And for best results, use a 4K monitor. I’ll have to admit that I don’t own one yet, but even my good old full HD Samsung monitor can make sense of the high quality movie.

Nissan has created a watch which uses the Bluetooth standard and is capable of monitoring the entire range of Nismo cars and their drivers. From what I know, it’s Nissan’s first attempt to creating wearable technology. The watch will not only monitor the car, but also the driver’s heart rate, among other things.

Nismo is Nissan’s in-house tuning and motorsports division.

A new NASA lunar mission has been recently launched, with the goal of creating an outer space Internet, which should provide faster download speeds, helping us receive space data much faster. Outer space cameras have captured a lot of data, especially images from Mars, but due to the low connection speeds, they are unable to send them fast enough to the Earth. With the new system, more data will be sent in less time.

More news from NASA: NuSTAR is a special spacecraft that can detect black holes. It has managed to detect 10 supermassive black holes so far. Most scientists think that this is just the beginning of a long series of similar discoveries. The ten black holes that NASA has discovered are called gargantuan structures. These structures are surrounded by thick gas layers. The telescope that has discovered the black holes was launched in 2012, with the goal of helping the astronomers understand the mysteries behind the black holes.
