HOW WE CAN PIN POSTS ON INSTAGRAM?

Instagram is testing out a pin-to-profile feature that lets you choose three posts to feature at the top of your profile grid. You can choose any three photos, videos or reels to pin. Users will be able to spotlight specific elements on their profile, e.g., most-liked post, major development in life, etc. Click on the three horizontal dots at the top right corner of the post you want to pin. Tap ‘Pin to your profile’ on the menu, and the post will show up at the top of your grid. If you change your mind about pinned posts, un-pin them by clicking ‘Unpin from your profile’ from the menu. If you don’t see the option to pin a post, then you don’t have access to the feature yet.

WHICH IS THE MOST VENOMOUS SNAKE IN THE WORLD?

The inland taipan is the world’s most venomous snake, but this Australian taipan is so shy that hardly anything was known about it by Western science for nearly a hundred years after it was first described in 1879.

The inland taipan’s alternative name, ‘fierce snake’, points to the potency of its venom rather than its behaviour. The other Australian taipan that it shares a common ancestor with, namely the coastal taipan, is far more aggressive.

The inland taipan lives in the remote black soil plains of the outback where the borders of South Australia and Queensland meet.

The inland taipan is most active in the early hours of the day, when it surfaces to hunt for prey and to bask in the morning sun. After a few hours it retreats back into its shelter for the remainder of the day, although in cool weather it may show up above ground in the afternoon too.

The inland taipan has adapted to the extremes of the outback climate by dramatic seasonal changes in its coloration. The color of its back varies from a dark brown to almost black in winter. During the summer months it changes to a pale straw color.

These color changes allow the inland taipan to control its temperature, with the darker markings efficient at absorbing heat and the lighter ones good at reflecting it. The head of the inland taipan is much darker compared to the rest of the body, which makes it possible for the snake to warm up quickly by exposing only its head to the sun.

The inland taipan is one of the few Australian snakes to specialize in eating mammals. It will mainly prey on small to medium-sized rodents, especially the native long-haired rat (Rattus villosisimus), though it will also eat the plains rat (Pseudomys australis) and the introduced house mouse (Mus musculus). The venom of the inland taipan is considered to be the most lethal of any snake, surpassing even the venom of sea snakes. It has evolved over time to be especially effective in killing mammals, which also makes it extremely toxic to humans.

The venom from a single bite is said to be enough to kill at least 100 men. On top of its extreme neurotoxicity, the venom also contains an enzyme called a ‘spreading factor’ that speeds up the absorption. An untreated bite has the potential to kill a person in 30 to 45 minutes, which makes immediate medical attention critical. If provoked, the inland taipan curves its forebody into a raised S-shape in an attempt to fend off the offender. This threat display also prepares the snake for striking.

WHAT IS MR. TRASH WHEEL DEVICE?

Mr. Trash Wheel, officially called the Inner Harbor Water Wheel, is a trash interceptor, a vessel that removes trash from the Jones Falls river as it empties into the Inner Harbor in Baltimore, Maryland. It is powered by water wheels and solar cells, and places trash from the harbor onto an onboard conveyor belt which routes it into dumpsters on the vessel. Mr. Trash Wheel was invented by John Kellett in 2008, who launched a pilot vessel at that time. A larger vessel was later developed; it replaced the pilot vessel and was launched in May 2014. The Mr. Trash Wheel vessel is part of the Waterfront Partnership of the City of Baltimore’s “Healthy Harbor Plan.”

Mr. Trash Wheel is a moored vessel that removes trash from the mouth of the Jones Falls river at Baltimore’s Inner Harbor. Rubbish from the streets of Baltimore is flushed into storm drains that empty into the Jones Falls river. The floating rubbish is then carried by the river to its outlet into the Inner Harbor, where it is captured by Mr. Trash Wheel. Mr. Trash Wheel is powered by the current from the river, and backup power is provided by solar panels when the current is sluggish. These power a conveyor belt. Mr. Trash Wheel removes flo

ating debris using rotating forks that dip into and out of the water, and which then place the trash onto a conveyor belt which moves it into a dumpster. The water wheel can be controlled remotely on the Internet. Mr. Trash Wheel was constructed using $720,000 of public and private funding.

WHAT’S THE DIFFERENCE BETWEEN THE SURFACE WEB AND THE DEEP WEB?

The Surface Web contains less than 10% of the info that is on the Internet.

The Deep Web consists of websites and content that are not searchable by standard search engines such as Google If Google can find the content you are searching for, then its on the Surface Web! The Surface Web contains less than 10 per cent of the information that is on the Internet.

Most people are unaware that the Deep Webs contains benign sites. Examples are your password-protected email and bank account certain sections of paid subscription services like Netflix and sites that can be accessed only through an online form. The Deep Web is estimated to be many many times larger than the Surface Web.
