Flash ads will stop working in Chrome from Sept 1st, 2015

In case your advertisements are not on the search giant’s network (Adsense), they better be in HTML5 – or they’re lifeless to Chrome. If they are already on the Adsense, then worry not, it probably has been converted to HTML5.

Google is making good on its promise to strangle Adobe Flash’s capability to auto-play in Chrome.

The online giant has set September 1, 2015 as the date from which non-essential Flash files might be click-to-play in the browser by default – effectively freezing out “many” Flash adverts in the process.

click to play
No more autorun

Users will have to right-click over the security-challenged plugin and select “Run this” if they wish to unfreeze a flash animation. Otherwise, the Flash files will stay suspended in a gray box, unable to trigger any malicious code on auto run.

Recently, back in June, Google warned that, in cooperation with Adobe, it will change the way in which Flash material is shown on web sites.

Mainly, “essential” Flash content (such as embedded video players) are allowed to automatically run, whereas unimportant Flash content, most of which are ads, shall be automatically paused.

As we explained a couple of months ago, it is effectively taking Chrome’s “Detect and run important plugin content” feature, and making it the default: only the “main plugin content on web sites” will be run automatically. That should put a stop to the irritating ads flashing all over the pages.

Most pundits believed that it was due to security reasons, however, Google’s reasoning for this move is largely performance-based, apparently. The second largest American company worries that with too many pieces of Flash content running at once, Chrome’s efficiency is hamstrung, and, more critically, battery life is drained in notebooks and tablets running the Flash plugin.

flash dead
Apparently, Flash is slow, inefficient and about to die. Is that hTml5 walking over Flash?

In June, on a blog post, Google’s software engineer Tommy Li put the blame squarely on Adobe’s shoulders and wrote that “Adobe Flash allows web pages to display rich content – but sometimes that can put a squeeze on your laptop’s battery”

Specifically, the culprit is the Adobe Flash plugin that comes built into Chrome and which automatically shows any Flash content it finds on web sites.

Crucially, the move will also help kill the spread of malware via malicious Flash files, particularly dodgy adverts which have popped up on sites used by millions and millions of individuals (hint: like Yahoo!)

Google mentioned that advertisers who’re apprehensive about having their adverts switched off should contemplate converting their Flash art work to HTML5. According to the cyber-Goliath, “most Flash adverts uploaded to [Google] AdWords are automatically converted to HTML5.”

Basically, in other words, if you’re not on Google’s ad network, you are locked out of Chrome – unless you also switch to HTML5.

Interestingly, Google’s security engineers have been helping Adobe’s programmers to shore up Flash with anti-hacker defenses. Google’s Project Zero team revealed that the version 18.0.0.209 of Flash – which was released to patch vulnerabilities exploited by spyware maker Hacking Team – employs three mitigations developed by Google and Adobe.

Carbon nano fibres made from thin air

Scientists in the US have discovered a method to take carbon dioxide (CO2) from the air and make carbon nano fibres, a useful manufacturing material.

Their solar-powered system runs a small current via a tank full of a hot, molten salt; the fluid absorbs atmospheric CO2 and tiny carbon fibres slowly form at one of the electrodes.

It presently produces 10 grams per hour.

The team says it can be “scaled up” and will have an effect on CO2 emissions, however other researchers are uncertain.

Nonetheless, the method provides a much cheaper approach of creating carbon nano fibres than present strategies, according to Prof Stuart Licht of George Washington University.

“Till now, carbon nano fibres have been too expensive for many applications,” he informed journalists at the autumn meeting of the American Chemical Society in Boston.

Carbon nano fibres are already utilized in high-end applications such as electronic parts and batteries, and if prices came down they could possibly be used more extensively – enhancing the strong, light-weight carbon composites used in aircraft and automotive parts, for example.

The question is whether or not the “one-pot” reaction demonstrated by Prof Licht and his group could help to drop that price.

At the moment 10 grams of nano fibres – like this sample Dr Licht brought to the convention – could be made per hour

The thought of turning CO2 from the air into useful products is a popular one, and the field is strewn with many more unfulfilled promises than success stories.

However Prof Licht is confident his design can succeed. “It scales up very easily, the entire process is quite low energy.”

Daring vision

He additionally suggested that the system could provide “a reasonable path to bring down CO2 levels within the environment”.

This would involve adopting the reactors on a colossal scale and the concept has raised some eyebrows.

Dr Katy Armstrong, a chemical engineer at the University of Sheffield, stated the method was “promising and very fascinating on a lab scale” however that Prof Licht’s bigger vision could be problematic.

“As they’re capturing CO2 from the air, the method will need to cope with large volumes of gas to collect the required quantity of carbon, which could increase process costs when scaled up”

The carbon nanofibres gradually build up on one of the device’s electrodes

Dr Paul Fennell, a chemical engineer and clean energy researcher at Imperial College London, stated: “If they can make carbon nano fibres, that is a laudable aim and its a worthwhile product to have.

“But if your idea is to take CO2 out of the atmosphere and produce so many carbon nano fibres that you make a difference to climate change – I might be extremely surprised if you may do this.”

Prof Licht insists it’s worth attempting.

“There are no catches; there is a necessity to work collectively, to test this on a bigger scale, to use some societal resources to do that,” he said.

In the meantime, other chemists were impressed by fact that Prof Licht’s crew had produced nano fibres from atmospheric carbon.

 

A small mistake helped scientists to quadruple battery lifespan

Until somebody figures out a alternative for lithium-ion in rechargeable batteries, research will continue into find out how to cram extra power inside as well as extending their useful lifespan. Two scientists believe they’ve managed to increase the life of such batteries significantly, and all due to an accident within the lab.

In the present day, lithium-ion batteries usually rely on graphite anodes to offer a long lifespan. Rechargeable battery performance declines and ultimately falls off a cliff (becomes unusable) because of these anodes repeatedly expanding and contracting as lithium ions migrate during the cycle of charging and discharge. Lithium compounds build up on the electrodes throughout this process then break off during the expansion and contraction. This exposes the surface of the electrode and over time decomposes it to the point of failure.

A better alternative to utilizing graphite for the anodes would be aluminum, however aluminum expands and contracts too much during each cycle. If scientists could stop that happening, we’d have much better performing batteries.

Dr Li Ju of MIT, USA and Dr Wang Changan of Tsinghua University, China and have been working collectively to stop the oxide coating that forms on the surface of aluminum nanoparticles when it’s exposed to air. Their idea was to soak the nanoparticles in a sulfuric acid and titanium oxysuplphate mix, which would dissolve the aluminum oxide and replace it with titanium oxide.

Achieving the new outer coating required a set time of soaking. The accident occurred when Wang and Li forgot to remove one batch of the nanoparticles from the soaking process. That batch ended up soaking for several hours longer than intended with the end result being the sulfuric acid and titanium oxysulfate mix leaked into the 50nm nano particles and dissolved some of the aluminum inside. What this left was a nano particle with a 4nm outer shell of titanium hydroxide and an inner 30nm “yolk” of aluminum.

The yolk and shell
A new “yolk-and-shell” nano particle could boost the capacity and power of lithium-ion batteries. The grey sphere at center represents an aluminum nanoparticle, forming the “yolk.” The outer light-blue layer represents a solid shell of titanium dioxide, and the space in between the yolk and shell permits the yolk to expand and contract with out damaging the shell. In the background is an actual scanning electron microscope image of a collection of these yolk-shell nano particles.

Rather than discarding this forgotten batch, they decided to test it by constructing batteries using these particles. It turns out they’ve potentially solved the problem of using aluminum for the anodes in the battery. The extra long soak meant the anodes didn’t expand and contract, in fact they created a battery that over 500 charge/discharge cycles retained as much as 4-times the capacity of the equivalent graphite anode batteries. These batteries last significantly longer in terms of usable lifespan and, according to MIT, can hold up to three-times the energy.

Clearly, sometimes being a forgetful scientist can lead to a breakthrough. The discovery is expected to be an easy one to scale up to mass manufacturing, which means the next-generation of rechargeable batteries may use aluminum anodes, bringing with it longer battery life per charge and batteries which have a much improved lifespan.

“These yolk-shell particles show very impressive performance in lab-scale testing,” says David Lou, an associate professor of chemical and biomolecular engineering at Nanyang Technological University in Singapore, who was not involved in this work.

“To me, the most attractive point of this work is that the process appears simple and scalable.”

The research team included Sa Li, Yu Cheng Zhao, and Chang An Wang of Tsinghua University in Beijing and Junjie Niu, Kangpyo So, and Chao Wang of MIT. The work was supported by the National Science Foundation & the National Natural Science Foundation of China.

 

Students want to make it to orbit, and they are close!

0

 

Last month, the Portland State Aerospace Society (PSAS), a student venture at Portland State College, launched a rocket out in the Oregon desert, on 19th July 2015 to be exact. The rocket soared almost five kilometers into the sky—an impressive feat, however that is just the start for PSAS. The group has its eyes set much higher.

In the video, you see the ground rapidly zoom away as the rocket, dubbed “LV2.3”, shoots into the sky. It is a beautiful sight—and one that was captured unintentionally.

“The digital camera falling out of the rocket was accidental,” chuckles Andrew Greenberg, an adjunct professor in Electrical and Computer Engineering at PSU who’s involved in the club. “In this case, the plastic cracked and the camera came out at Mach 1.” The Raspberry Pi-based camera was supposed to record from the side of the rocket’s payload module. “3D-printing plastic isn’t necessarily great for rockets, it turns out.”

The membership’s targets are loftier than just getting just a few kilometers above the Earth. When asked about the objective of the club, Greenberg is direct. They want to put a nano-satellite into orbit.

The PSAS in 2011
The PSAS in 2011

“We try to build as much as we can,” says Greenberg. When you’re trying to construct a space-bound rocket, the to-do list is spectacular. “We’re building our own avionics system. We are making our own software-defined radio GPS system. We’re building our own Ethernet-based systems. We’re using WiFi as a long distance telemetry on the amateur radio band.”

The plan to construct a nano satellite (particularly a CubeSat) came to the group during all of this tinkering. After an inspired burst of DIYing, they realized their computer for getting the rocket to space was fairly close to functioning as a tiny satellite. Now they had to figure out how to give it a second life in orbit.

Usually CubeSats function as small satellites that do their business only after they’re in orbit. They’re deployed out into space as a ten centimeter cube that then conducts scientific research within some particularly outlined parameters. It doesn’t usually deal with avionics for a rocket. However PSAS’s CubeSat does both the work. “Our CubeSat has an Ethernet peripheral called ‘a rocket,’ and it flies up and drops itself off and throws itself into space and then it becomes a satellite,” Greenberg says. “All that is, is a change of software, right?”

“WHEN YOU’RE TALKING ORBITAL-CLASS ROCKET, THERE ARE A BILLION THINGS TO DO TO PROVE IT’S SAFE.”

The technological hurdles are one thing. The bigger impediment keeping Portland State Aerospace Society from reaching orbit? “Think ‘cash and lawyers,'” says Greenberg. Including the Portland State Aerospace Society, there are other amateur teams that might potentially put something into orbit​ like the Boston University Rocket Propulsion Group and Delft Aerospace Rocket Engineering in the Netherlands. Actually, the Civilian Space eXploration Team (CSXT) made it a hundred and fifteen kilometers into the sky (which is, by all definitions, space) in 2004. However there’s no amateur group putting stuff in orbit just yet.

history of rockets
History of PSAS launches

All of them face the same issues of international law, regulatory compliance, safety evaluation, and a litany of different hurdles. “As soon as you begin talking orbital-class rocket, there are a billion issues you need to do to prove that your rocket is safe,” Greenberg says. “Minneapolis-St. Paul does not like it when you drop your first stage on them.”

These are complex issues even for massive corporations like SpaceX. It is even harder for a small group of hobbyists. “If someone drops out of the sky and says, ‘Here is $10 million, and here is a cadre of attorneys for you to use,’ we would happily do it,” says Greenberg. “But we do not expect that to happen.” They currently make do on between $3,000 and $10,000 a year in fundraising, however sooner or later these hurdles will become an issue that will require serious cash to solve. For now, the group chooses to focus on better rockets & avionics.

Then again, Greenberg and the Portland State Aerospace Society have a history of overcoming setbacks. In 2005, they had been at the cutting edge of amateur rocketry. “We had the world’s most superior avionics system,” Greenberg says. “It was a Linux-based computer that used the controller area network that is used in automobiles. It had every thing our current rocket has, but it was way ahead of its time.” He is fairly sure it was the first time, for example, people had used WiFi in rockets.

“We launched it, and it worked beautifully. Everything we thought would fail, like the software and the radios, worked perfectly.” The one piece that did fail? The parachute. “We lawn darted that thing at close to Mach 1 into the ground,” he laughs.

The loss of the rocket set the group back badly—they did not launch another rocket for 4 years—but they learned from their mistakes. “We construct three of every thing, so if we lose one thing that is okay.” If the group can recover from smashing up one of their best rockets, who’s to say they could not figure out the attorneys and regulatory angle as well?

In the meantime, the group has their hands full with a brand new “LV3” airframe they’re hoping could eventually attain a hundred kilometers (or about sixty two miles). “100 kilometers is the magic number,” Greenberg says giddily. “You get to say you are in space if you have gone 100 kilometers.”

They’ve already made it 5 kilometers. What’s one other ninety five?

MicFlip : The World’s 1st Reversible Micro USB Cable

There was a lot griping when Apple changed its outdated dock connectors with the reversible Lightning cable, however they’ve made life much simpler for Apple customers. So the MicFlip, the world’s first reversible micro-USB cable, guarantees to do the same for Android, Nokia (and other smartphone) users.

MicFlip in action
MicFlip: First reversible MicroUSB ever

Have you ever tried plugging a micro-USB cable into your cellphone, tablets or any other gadgets in the dark? You’ve got a 50% probability of getting the connector the proper side up, however in actuality you often get it wrong 99% of the time. Not with the MicFlip. It works both way so every time you try to plug in a microUSB device, it’s guaranteed to work.

Of course, the angle of the plug was not the only important thing to regular USB cable users. 25% of respondents to the survey carried out by UK based Winner Gear said they wished their cables were more reliable. USB cables can become faulty fairly quickly, with connections becoming loose and proving unable to charge gadgets or transfer data. To overcome this problem, MicFlip is not only totally reversible, the wires are also covered in an ultra-strong and flexible braided nylon lead. The cables have a robust aluminum shell, and gold-plated plugs to prevent corrosion, ensure greater conductivity. The creator’s claim that MicFlip will outlast all of your other USB cables.

The MicFlip’s creators selected Indiegogo crowdfunding site to help bring the cable to the frustrated and challenged charging masses, but as of right now, it has already surpassed its funding goal by a long margin. When available sometime in September (assuming everything goes smoothly moving into product testing and manufacturing) the reversible microUSB will retail for about $20, however pre-orders are still out there so you can buy one now for just $15 and save your self a few dollars. Literally this is a feature many people want, our only criticism is that they didn’t show one actual cable in action, but only artist renderings.

Or, purchase a dozen since you’re in all probability just going to want to go ahead and replace every annoying microUSB cable in your home. Now just wish that someone makes that main USB connector as reversible too!

The Ladder made of Fire(works) into the Sky

A fiery, eighty-second artwork from earlier in the summertime that seems to indicate a towering ladder made of fireworks is going viral.

It was Guoqiang’s third attempt at creating Sky Ladder. In 1994, the artist attempted a similar show, but strong winds hindered the progress. In 2001, he tried again when China hosted the APEC summit, but restricted aerial access due to the Sept. 11, 2001 attacks meant that Guoquiang’s dream installation was again put on hold.

This beautiful installation, by artist Cai Guoqiang, occurred in June in Quanzhou Metropolis in China’s southeast Fujian Province. It was carried out utilizing a big weather balloon pulling on a 500-meter long wire ladder studded with fireworks and gunpowder, according to Yahoo News.

Sky Ladder, referred to by some as a “stairway to heaven,” was dedicated to the Cai’s grandma, who recently celebrated her 100th birthday.

Scotland has Banned GM Crops

0

Scotland is to ban the farming of genetically modified (GM) crops, the nation’s rural affairs secretary announced on Sunday.

Richard Lochhead stated that the Scottish government was not ready to “gamble” with the future of the country’s £14 billion food and drinks sector.

Farming leaders were disappointed by the move.

Under European Union (EU) rules, GM crops must be formally authorized before they can be cultivated.

An amendment came into force earlier this year which permits member states and devolved administrations to restrict or ban the cultivation of GM organisms within their territory.

‘Consumer backlash’

Mr Lochhead said Scotland’s request for opt-outs from GM crop consent would cover an EU approved variety of genetically modified maize and 6 other GM crops which are awaiting authorization.

He stated that Scotland was recognized around the globe for its “beautiful natural environment” and banning the growing of genetically modified crops would protect and further enhance its “clean, green status”.

Mr Lochhead added: “There isn’t any proof of significant demand for GM merchandise by Scottish consumers and I’m concerned that permitting GM crops to be grown in Scotland would damage our clean and green brand, thereby gambling with the future of our £14 billion food and drink sector.

“Scottish food and drinks is valued at home and overseas for its natural, high quality which often attracts a premium price, and I’ve heard directly from food and drink producers in other nations who are ditching GM due to a consumer backlash.”

The announcement was welcomed by Scottish Green MSP Alison Johnstone, who agreed that the cultivation of GM crops would hurt the country’s environment and reputation for high quality food and drinks.

However she called on ministers to go further by challenging big retailers to improve their labeling to point out whether or not meat, eggs and dairy products come from animals fed on GM feed.

‘Embracing biotechnology’

The move has also been broadly welcomed by environment groups.

However Scott Walker, chief executive of farming union NFU Scotland, stated he was disappointed that the Scottish government had determined that no GM crops should ever be grown in Scotland.

“Other countries are embracing biotechnology where appropriate and we should be open to doing the same in Scotland,” he stated.

Huw Jones, professor of molecular genetics at agricultural science group Rothamsted Research, said the announcement was a “sad day for science and a sad day for Scotland.”

He mentioned that GM crops approved by the EU were “safe for people, animals and the environment”.

Install Windows 10 using the ISO file

0

Microsoft has come up with its best Operating System (OS) so far, The MS Windows 10. Initially it is available for free for many users as an upgrade to their Windows 7, Windows 8 or Windows 8.1. For those people who can’t see it as an upgrade option, or for people who were on different OS such as Windows XP, Ubuntu or different flavors of Linux, we have prepared this simple guide to help you install Windows 10, using the official ISO file from Microsoft.

windows 10 iso download and booting

Before we begin Microsoft Windows 10 ISO download, you will need:

  • An internet connection for windows 10 iso download to your PC/laptop computer.
  • Sufficient storage space in your PC or laptop (It may require more than 3 GB).
  • A blank USB or a DVD which has minimum of 4GB empty space.
  • Your system should also meet these system requirements.
  • If you are installing for the first time you will need the product key. For more information, go to FAQ page.

First of all, we’ll download an image file of windows 10.

Click here to download the windows 10 iso file to your pc/laptop. (Alternatively, you can download it using torrents, Click here to download the 64-bit version, and here to download the 32-bit version) It’ll ask you whether you need the 32-bit or 64-bit version. If you are not sure, as a rule of thumb, if you have 4gb of RAM in your system, or more, you’ll need the 64-bit version, otherwise you are fine with the 32 bit one.

After downloading complete, you have to make a bootable USB or bootable DVD for windows 10 installation on your laptop/pc.

We suggest using a USB (pendrive) as they are faster, easier to carry and more durable then a DVD. Plus, unlike a DVD ROM, you can plug in a USB in almost any system out there.

To make a bootable Windows 10 installation USB, we recommend using the free version of Win To Flash. You can also use the official Microsoft USB tool, but we don’t recommend it as it is too buggy.

After you have created a USB, plug it in and restart your system. Go to the BIOS setup (usually by pressing F-12 or DEL) and make sure, in boot selection, USB is selected above your hard disk. Save and exit. When your computer will start, it should automatically take you to the Windows 10 setup.
From there, its as simple as ABC. If you have any trouble, you can ask for help in the comments below.

Users of Yahoo hacked because of Flash

4

Researchers at Malwarebytes, an anti-malware vendor, uncovered a large scale attack targeting Yahoo customers via Yahoo’s advertising network. Malwarebytes notified Yahoo about it and the “malvertising” marketing campaign is now no longer in progress.

The attack was possible as a result of Flash vulnerabilities in unpatched versions of Flash, even perhaps the same vulnerabilities that force Mozilla to block Flash by default in its browser for a number of days until Adobe released a patch. Not all Flash users have updated to the latest version, though, which implies they’re still susceptible to these highly dangerous security exploits.

Yahoo owns large Web properties with an estimated 6.9 billion monthly visits, based on data from SimilarWeb, which implies even if a small proportion of those visits resulted in malware installation on the users’ PCs, it might still affect millions of individuals.

Malvertising is particularly dangerous because it requires no action from the user, and it can download and install itself automatically on the user’s PC (assuming the user is on a Standard account and not an Administrator one, and the User Account Control protection is weak enough to be bypassed, or the malware makes use of native privilege escalation zero-days).

The malware can even install “ransomware” on users’ computers and lock their files till the customers pay the criminals.

Recently, Flash has been a lot in the news, with even Facebook saying it hurts their business. Apple and Twitch have already ditched Flash. Users are advised to either update their version of Flash or disable it completely.

We at GadgTecs think Flash should be abandoned by now. HTML5 is not perfect, but much secure and better alternate.

 

 

Upgraded: The flying car called the Terrafugia TF-X

Flying cars have probably been on the back of people’s from the time cars were invented. Many have daydreamed of having one, movies have come come up with concepts and ideas and a few have attempted or are attempting to actually build one.
Humans have gotten fairly good at waiting patiently for a flying car. If we’re being sensible, it might take a long time to produce them and get them into circulation. Many people who dreamt about this won’t be alive by the time one actually rolls of the garage of a common man.

The Italian firm Terrafugia isn’t letting all of that hold it back though – it has released new designs for the TF-X, and still in scale testing, they appear to be very classy. It will require no runway to take off, will have a maximum cruising speed of 200 mph and would be able to fly for about 500 miles.

First announced in 2013, the TF-X is a 4-passenger hybrid automobile, which will able to recharge its batteries both from its engine or by plugging in to an electrical charging station. It is going to be sufficiently small enough to get parked inside a regular garage, and will hopefully be street legal.

If you wish to go into flying mode, the wings will fold out, and twin electrical motor pods on the ends will power up and raise the vehicle off the ground using 1 MW of energy. 2 small helicopter-type propellers will give the required thrust when wanted, and are then folded again when the car is cruising on the road.

An artists impression. Score: Terrafugia

Flying will be computer operated, so drivers don’t have to worry about knowing how to navigate an airborne car. The Terrafugia website explains that prior to departure, the driver will choose a primary landing zone, plus two backup touchdown zones. If the TF-X calculates inadequate power on board to at least be able to land at one of the two backup landing zones in an emergency, and then make it to the final destination in half-hour, it won’t take-off. It’ll additionally not embark on a flying journey if the weather forecast appears dangerous, or if any of the chosen landing zones are in restricted airspace.

“Operating a TF-X car should be statistically safer than driving a modern automobile,” they claim.

Right now, we are  still looking at 8-12 years of development for the Terrafugia TF-X. They’re yet to produce a prototype of the design, however they’re about to test a one-tenth scale model at the MIT Wright Brothers wind tunnel in the United States. “The wind tunnel test model will be used to measure drag, lift and thrust forces while simulating hovering flight, transitioning to forward flight and full forward flight,” the company says.

Can’t wait until the video above becomes a reality. Till then, daydream on…
