Twitter says it has suspended more than 70,000 accounts associated with the far right QAnon conspiracy theory following last week’s U.S. Capitol riot.

The social media company said Tuesday that given the events last week in Washington, D.C., where a mob of pro-Trump loyalists tried to violently storm the Capitol building, it was taking action against online behavior “that has the potential to lead to offline harm.”

In many cases, a single individual operated numerous accounts, driving up the total number of affected accounts, the company said in a blog post.

“These accounts were engaged in sharing harmful QAnon-associated content at scale and were primarily dedicated to the propagation of this conspiracy theory across the service,” the company said.

Twitter’s sweeping purge of QAnon accounts, which began Friday, is part of a wider crackdown that also includes its decision to ban President Donald Trump from the service over worries about further incitement to violence.

The suspensions mean some Twitter users will lose followers, in some cases by the thousands, the company said.

The QAnon conspiracy theory is centered on the baseless belief that Trump is waging a secret campaign against “deep state” enemies and a child sex trafficking ring run by satanic pedophiles and cannibals. Twitter has previously tried to crack down on QAnon, removing more than 7,000 accounts in July.

Twitter said it’s also stepping up enforcement measures and starting Tuesday it will limit the spread of posts that violate its civic integrity policy by preventing anyone from replying to, liking or retweeting them. The policy prohibits attempts to manipulate elections and spread misleading info about their results, with repeated violations resulting in permanent suspension.

Since 2019, Oppo produces premium smartphones under the Reno series. The Reno phones are highly admired for their stylish looks and excellent camera features. In this legacy, Oppo has launched its new invention Oppo Reno5 on January 9 in Bangladesh. If you are looking for the best Camera Phone under Tk 40,000, then don’t miss the Oppo Reno 5 full review with Price in Bangladesh.

Oppo Reno 5: Review of Key Features

Design

At the first sight, you will be enthralled by Oppo Reno5’s elegant look. When you hold the smartphone, you would get a premium feel. In the box, you will get the Oppo Reno5 Smartphone, Charger, Earphones, USB Data cable, SIM Ejector Tool, Protector Case, and essential papers. Reno 5 comes in two colors: Fantastic Silver and Starry Black.

Though Reno5’s rear-panel is made of polycarbonate, it looks like glass. In this price range, customers usually expect a glass-built back panel. However, the gorgeous slick design (159.1 x 73.3 x 7.8 mm) of Reno5 won’t let you complain about its build quality. Thankfully, its glossy back-panel won’t catch many fingerprints. But still, you need to use the protector case, to preserve the sheen of its smooth surface.

Reno5 features excellent weight-balance ratios that make this phone very lightweight (171g). Like its ancestor Reno4, the latest 5 version bears a 6.4-inch display. It can be a drawback when you prefer large-screen phones.

The power button is on the right side. On the left side, you will find the volume rocker and SIM card tray. On the upper edge, it has a secondary noise cancelation microphone. The 3.5mm headphone jack, bottom-firing speaker grill, primary microphone, and USB-type C port lie on the bottom edge. The provision of stereo speakers would have been better.

On the left side of its front screen, there is a single punch-hole camera. In this phone, you get an in-display fingerprint scanner. It works fast and accurately. On the rear pane, it has camera housing. The camera bump is low.

Display Quality

Reno5 sports a 6.4-inch AMOLED panel. Its amazing 91.7 percent screen-to-body ratio offers a premium feel. Here you get a Full HD+ display at 2400 by 1080p resolution. Reno5 offers two options for refresh rate: 60Hz and 90Hz. For the first time, Oppo is combining a high refresh rate with an AMOLED display. It is certainly good news for the Oppo fans!

Oppo claims that Reno5 has a Default touch-sampling rate of 120Hz (for five fingers) with an utmost rate of 180Hz (for two fingers). The mind-blowing touch-response performance offers a great user experience.

Reno5 features about 430 nits of typical brightness. Interestingly, when you use this phone in direct sunlight, the brightness can reach up to 600 nits. It is a very handy option for people who stay outdoor for long hours. What is more? Oppo Reno5 out wins many competitors with an amazing pixel density of 410PPI.

The superb color contrast ratio and mesmerizing color punches of its AMOLED display would make your movie/video watching experience much more exciting. The display is protected by Corning Glass 3+. However, a higher version was expected in this price range.

With WhatsApp literally forcing users to agree to sharing information with its parent company Facebook, more and more people around the world are migrating to other instant messaging apps like Signal and Telegram. India is no exception, where WhatsApp users are increasingly shunning WhatsApp for Signal and Telegram.

Both Signal and Telegram claim to have “state-of-the-art end-to-end encryption” as part of their services and are free to download. Ironically, Signal is headed by Brian Acton, one of the co-founders of WhatsApp. Signal has features like voice calling, video calling, stickers support and the person-to-person chat interface, similar to that of Apple’s iMessage.

Signal witnessed some 7.5 million installs globally through the Apple App and Google Play stores from January 6-10, according to California-based mobile analytics firm Sensor Tower. Similarly, Telegram saw over 5.6 million downloads globally in the same period. In India, a million have downloaded Signal and Telegram in the past week, according to estimates.

"Though WhatsApp is a household name in India, people have started migrating to other more privacy-focused messaging apps, particularly Signal. The figure, as per our estimates, is at least a million. The figure represents those shunning WhatsApp as well as new users," technology expert Rahul Gaba told UNB.

"So, it's privacy over convenience, for Indians, particularly the urban class. Moreover, the trend clearly shows that Signal is going to gain more ground in India," Gaba added.

WhatsApp recently rolled out notifications informing users about an update in its Terms of Service that would pave the way for the app to share data with Facebook. WhatsApp made it clear that users will have to agree to the new terms and policy by February 8 this year, in order to continue using the instant messaging service.

WhatsApp's move to collect user information has already prompted electric carmaker Tesla founder Elon Musk to urge social media users globally to switch to Signal. Musk, in fact, recommended Signal on January 7, following which the shares of the app zoomed more than six-fold on the US bourses in a single day.

Soon after the announcement, Signal app had said in a tweet: "We continue to shatter traffic records and add capacity as more and more people come to terms with how much they dislike Facebook's new terms. If you weren't able to create a new group recently, please try again. New servers are ready to serve you."

That day only, Signal tweeted to inform WhatsApp users how to move their groups to the app using a group link. "A lot of people have been asking how to move their group chats from other apps to Signal, and Signal group links are a great way to get started. Drop a group link into your former chat app of choice like you're dropping the mic on the way out."

Musk, also the founder of SpaceX, has now pledged to invest more in Signal. In response to a tweet by the CEO of an e-commerce business on January 11, Musk said that he will invest again in Signal. “Already donated to Signal a year ago. Will donate more," he tweeted.

WhatsApp users in India say they are more than happy to migrate to Signal and Telegram. "Initially, I had a mental block using Signal, having used WhatsApp for the past 2-3 years. Gradually, I am getting over the mental block. I am also encouraging a number of my friends to switch to Signal at the earliest," said Manasi Roy, a software professional based in Delhi.

In fact, Gaba said he became apprehensive of WhatsApp's security features since the surfacing of private exchanges between Bollywood celebrities in the media amid the probe into the death of actor Sushant Singh Rajput. "It clearly indicated that WhatsApp had been sharing data with Indian probe agencies," the expert added.

What if you could charge your mobile phone without conventional electricity, but with a bottle of hot water instead? Space thermoelectric technology could soon make this sustainable solution a reality.

Thermoelectric devices are made from materials that can convert a temperature difference into electricity. Previous researches have suggested that thermoelectric devices can harvest wasted heat and produce electrical energy to back up the battery on spacecraft.

Chinese scientists are now hoping to take advantage of space thermoelectric technology to benefit people's daily life.

Researchers at the China Academy of Launch Vehicle Technology, one of the country's rocket makers, have developed a type of insulated water bottle equipped with a thermoelectric chip that can turn water heat into electricity to charge a mobile phone.

As mobile phones have gotten more powerful processors and larger touch screen interfaces, their power requirement has correspondingly increased. However, people often face the problem of charging their phones, especially when traveling on trains or camping in mountains, said lead researcher Ma Wei.

"Our solution to this problem is a water bottle-based thermoelectric device, a heat source to generate electricity," Ma said, adding that the invention does not require any electrical sources.

A demonstration video showed that the thermoelectric device was embedded in the bottle cap, which has a USB charging port on it. When a researcher connected an iPhone to the bottle with a cable, the battery icon on the screen appeared green with a lightning bolt indication in the middle.

"We have found that the water bottle can provide 20 to 30 minutes of electricity after we poured 300 to 500 milliliters of boiling water into it," said Sheng Jiang, a member of the research team.

The bottle can also provide electricity for laptops, cameras and other low-power household appliances.

Researchers are now seeking to forge cooperation with enterprises to market the concept. The product is likely to be priced from 150 yuan (about 23 US dollars) to 200 yuan.

A thermoelectric chip might make the bottle 200 grams heavier than the same size product on the market, but Sheng said it would be easy to carry as researchers have reduced the bottle weight by the use of a light heat insulation material, originally created for spacecraft, to replace stainless steel container.

Emphasising the safety of the invention, Sheng said it produces low voltage and has no risk of short circuit.
