New Nevada Law For Selling Private Data Is About To Become Effective

Online privacy has been an extremely hot topic in recent years. In an interesting recent development, the state of Nevada has taken some initiatives in this area, introducing a bill that allows Nevada residents to opt-out from having their information resold by tech companies.

This law was signed in May and requires online companies to comply with users’ requests to not share their personal data, else they could face serious fines.

The law is titled ‘Sentate Bill 220’ and was based on the California Consumer Privacy Act (CCPA). It should go into effect on January 1, 2020.

Various tech companies have argued that such laws should be national, and that state laws such as this one are very difficult to follow. However, those in favor of increased privacy laws tend to praise state laws, as they often argue they will be more stringent than a national law that makes it into Congress.

Fortnite Season X is Almost Done! Whats Buzzing and What’s not?

Ever since the launch of season X, Fortnite’s fan base have been going through a whirlpool of emotions. From bringing back old favourite POIs to crossovers with other game brands, Epic has been experimenting with various formulas to keep their fanbase happy.

Being the most played game in the planet at the moment, Fortnite has casual and full-time professional players. The game has now completed 10 seasons and Epic is still trying to find a middle-ground between the pros and the casual players. Season 9 was all about transportation and allowed players rotate between cities almost instantly with various forms of travel. In season X, hoverboards are the only vehicle-mode of transport that remains from the previous seasons. This is one among the many changes that have been incorporated in season 10.

Let’s sort these changes by “ Buzzing” and “Not so Buzzing”

The Buzzing Season X Changes

Old OG locations are back: Dusty depot, Retail Row and a new Tilted town now exist in the season 10 map. Tiled town has an added twist of “No Building and No Breaking” within the city. Retail Row is now loaded with different sized zombies.

Crossover Content : Paradise Palms now has an area dedicated to the upcoming Borderlands 3 video game. Players can drop into a specific area of the map and a borderlands filter is applied to the game, allowing players to experience the “comic” like visuals associated with Borderlands.

Map Changes Expected Every Week: Since the start of season X a rift beacon appears at a random city hinting for changes to happen within that city in the next available update. The old floating island located at loot lake can now be found at Fatal fields, along with the return of Kevin the cube.

New fun items are still being added: Items such as the zapper trap, junk rifts and fully automatic sniper have been introduced in season X. By the looks of it, the developers seems to be well on track to add more weapons, traps, healing items into the game.

The Not so “Buzzing” Season X Changes

B.R.U.T.E.S: Fortnite has never received more criticism for a change than introducing the “B.R.U.T.E” into the game. This giant sized robot can fire back to back missile, stomp through building and other such structures. The whole community raged with regards to how overpowered the B.R.U.T.E is and surely this might be Epic’s biggest regret of the season.

No more Combat Shotgun: In season 9, Combat shotgun came into the game giving players the ability to fire rapid shotgun shots and kill fully shielded opponent in under 2 seconds. Well, now they’ve removed it from the game forcing players to opt for the pump or tactical shotguns.
With just a third of the season remaining, Fortnite developers have many other surprises in store. Rift beacons are still popping up all over and changes to the map are inevitable. A Fortnite crossover with the upcoming movie “IT chapter 2” is what’s beyond the horizon for the coming week.

What are your highlights for season X?

Lithium battery fires could be prevented using graphene coating, study says

Researchers from the University of Illinois at Chicago College of Engineering have published a paper in journal Advanced Functional Materials wherein they have suggested that a thin coating of graphene could help protect fires in lithium batteries.

Over the last few years there has been a surge in the use of lithium batteries – primarily due to their size and energy density – in the electric vehicle segment. Lithium batteries hold the promise of allowing electric vehicles to travel several hundred miles on one charge. However, there is one problem that affects their increased use – occasional fire – an occurrence known to battery researchers as “thermal runaway.” These fires occur most frequently when the batteries overheat or cycle rapidly. With more and more electric vehicles on the road each year, battery technology needs to adapt to reduce the likelihood of these dangerous and catastrophic fires.

Researchers report that graphene may take the oxygen out of lithium battery fires. If the oxygen combines with other flammable products given off through decomposition of the electrolyte under high enough heat, spontaneous combustion can occur.

Scientists knew that graphene sheets are impermeable to oxygen atoms. Graphene is also strong, flexible and can be made to be electrically conductive. Scientists thought that if they wrapped very small particles of the lithium cobalt oxide cathode of a lithium battery in graphene, it might prevent oxygen from escaping. First, the researchers chemically altered the graphene to make it electrically conductive. Next, they wrapped the tiny particles of lithium cobalt oxide cathode electrode in the conductive graphene.

When they looked at the graphene-wrapped lithium cobalt oxide particles using electron microscopy, they saw that the release of oxygen under high heat was reduced significantly compared with unwrapped particles.

Next, they bound together the wrapped particles with a binding material to form a usable cathode, and incorporated it into a lithium metal battery. When they measured released oxygen during battery cycling, they saw almost no oxygen escaping from cathodes even at very high voltages. The lithium metal battery continued to perform well even after 200 cycles.
