As a car lover, you have to check your car’s battery to avoid failing you when running errands or doing your job. A fully functioning battery equals fun driving. Most of the time, your battery might still be fairly new but will still have you questioning its functionality as it does not retain its power. Here are the reasons that cause your car battery to fail.

Faulty Charging

When the charging system is not working correctly, your battery can drain; even when driving almost all the time, your car battery power plays music and other systems from the alternator. This practice can quickly drain your car faster, mainly because your vehicle has a charging problem.

Excess short Drives

Your battery is meant to drain before you use it. When you choose short drives, this is because the battery puts more power, especially when starting the car, and of course, with short drives, you shut off your alternator before it fully charges it, leading to the battery dying and not being long-lasting.

Old Battery

Once a battery is old, it equates to being weak; thus, not being able to hold for a full charge of an old battery would make starting your car difficult. It would be best if you replaced your battery when it has lasted like four years to avoid it dying on you when driving.

Human Error

This is one as a car owner you are responsible for. Remember those few times you leave your headlights on, forget to close your boot, or forget internal lights on for long hours, which mainly results in your battery draining, and when you want to restart your car, it doesn’t restart.

High Temperatures

When it’s scorching, like over 100 degrees, it can lead your car lead Sulphate crystals to build up.
Hot weather hinders chemicals inside car batteries as they make it hard for the battery to hold a charge and produce enough power.

Corroded Battery Cables

Check your battery cables; for signs of corrosion, buy new ones as with these corroded ones they always fall off the battery while driving for the dirty ones clean them using a cloth and check for loose ones they always make it hard for the engine to start as they hinder the transfer the electrical current correctly.

Ensure to replace the battery after four years of service and change the cables when corroded. And as a car owner, you have to be responsible. Don’t leave headlights and internal car lights on to void draining your car battery.

Facebook changed its corporate name to Meta on Thursday, moving aggressively to distance itself from a social-media business embroiled in crisis and rebrand itself as a forward-looking creator of a new digital world known as the Metaverse.

In a 75-minute online presentation, CEO Mark Zuckerberg urged users to adjust their thinking about the company, which he said had outgrown its ubiquitous and problematic social media app — a platform that will continue to be known as Facebook. Instead, he said, the company plans to focus on what Zuckerberg described as the next wave of computing: a virtual universe where people will roam freely as avatars, attending virtual business meetings, shopping in virtual stores and socializing at virtual get-togethers.

“From now on, we’re going to be the metaverse first. Not Facebook first,” Zuckerberg said at Connect, the company’s annual event focused on virtual and augmented reality. “Facebook is one of the most-used products in the world. But increasingly, it doesn’t encompass everything that we do. Right now, our brand is so tightly linked to one product that it can’t possibly represent everything we are doing.”

The revelations by whistleblower Frances Haugen represent arguably the most profound challenge yet to Zuckerberg and his company, which ranks as the largest social media platform in the world. Critics swiftly criticized the move, comparing it to the crisis strategy employed by tobacco company Phillip Morris when it became clear that the company had long known that cigarettes damage human health.

Zuckerberg said the rebrand would heed the “lessons” of the past, noting in a blog post that privacy and safety would be built into the new generation of products “from Day One” — a clear nod to Facebook’s record of eroding trust. In his keynote address, he also nodded to Facebook’s problems, saying, “The last few years have been humbling for me and my company in a lot of ways.”

Also, read Facebook has not yet announced a decision on whether the former president will be restored to its platforms.

But Facebook’s trust deficit is real. The crisis brought on by the Facebook Papers, which were provided to Congress and the Securities and Exchange Commission in response to a whistleblower lawsuit, follows other scandals in recent years, such as Russian disinformation surrounding the 2016 presidential election and the Cambridge Analytica crisis that highlighted the improper sharing of personal data.

One of the major allegations of the Facebook Papers is that the company built and deployed social media technology without having a grasp of its harmful effects. Critics fear the same problems would plague the metaverse — only the stakes could be higher, as Zuckerberg pitched that people would essentially live part of their lives in his virtual world.

He sought to offset potential criticism by saying in his presentation that the next generation of Internet services would be built with greater “humility and openness,” and take the “lessons” of the past into account. But critics and some former insiders questioned that commitment.

“I was thinking during the keynote, who will be the cops in the metaverse?” said Katie Harbath, founder and CEO of consultancy Anchor Change and former Facebook public policy director. “The first few years may seem great because not that many people are on the service, but the more that come on, the more bad actors. And then the company plays catch-up.”

For the time being, Facebook’s name change seems aspirational. A company that Zuckerberg launched from a college dorm room 17 years ago has become a conglomerate encompassing WhatsApp, Instagram, Messenger and a nascent payments and hardware business, leading some experts and insiders to say that the company was long overdue for a name change.

But virtually all of Facebook’s revenue — $29 billion in the third quarter — comes from online advertising produced by the core blue Facebook app, meaning that any transition to virtual reality focused on the sale of hardware would take enormous investment and many years.

“While the name change indicates a larger vision, that transformation is not yet a reality and will be a years-long investment,” eMarketer analyst Audrey Schomer said in an email.

Zuckerberg and Facebook have acknowledged that. Zuckerberg said in his keynote that the process to become a metaverse company would take a “decade” and that his goal was for it to “reach a billion people” over that time. On Monday, the company said its investments in the metaverse — which include a commitment to hiring 10,000 new people in hardware jobs — will shave $10 billion off its 2021 profits.

China has developed a new underwater robot that can fire cruise missiles at potential enemies in the ocean. The new weaponized robot is part of a military program called «Drone Warriors», which was developed by the PLA Navy.

China has built a shark drone to help it spy on and hunt down enemy ships and submarines.

The stealthy sea robot can move at speeds of six knots and will help conduct reconnaissance as well as search and destroy missions for the country’s military.

Developed independently by Beijing-based Boya Gongdao Robot Technology, the unmanned device was unveiled at the 7th China Military Intelligent Technology Expo on Monday.

And it has already been deployed for use by the forces.

Most such drones can be fired out of a sub’s torpedo tube, but it is unclear how the Robo-Shark will be launched.

it’s been rumored for years that the People’s Republic of China is mass-producing and/or designing new military drones. Now, according to recent reports, that secret is out. The People’s Liberation Army (PLA) has begun testing a new type of semi-autonomous underwater vehicle (SAW) called the Type 055 underwater combat vehicle (UCV) or “”””cannon drone”””” for short. The names are significant: The cannon drone is the first Chinese weaponized underwater vehicle to utilize a radar guidance system–a key requirement for an underwater attack. The development of this vehicle comes just six months after China’s first operational deployment of a nuclear-powered aircraft carrier group to the Western Pacific.
