WhatsApp is testing a Beta feature to speed up the playback of voice messages After a short activation, WhatsApp released a new version of Android beta 2.21.9.5 to disable this feature. This is arguably another surprise, because WhatsApp typically tests features for a few months before rolling out to public beta testers. This could be a buggy update from WhatsApp and has been quickly fixed. The interface for this version of WhatsApp has also been changed to better accommodate the new features. An icon appears right next to the voice message to perform accelerated operations that the user wants to hear again. In addition to playback acceleration, another feature also tested by WhatsApp is the ability to delete or make changes to a chat on just one active device without affecting any linked devices other. That is, changes or deletion of any chats through one handset will not be deleted from other linked devices. This is quite confusing because often performing a delete or change operation means that the content the user will not want to save on any device. If this feature is kept by WhatsApp, users will have to delete the chats multiple times on multiple devices. This feature is in line with what WhatsApp introduced previously, which is that each account can be importing up to 4 devices at the same time. However, the log out of all these devices is said to be in development, users still have to go to each device to remove the WhatsApp account. The new features that WhatsApp has introduced well for users to try out may see that it may be coming to many people soon.

As it turns out, the act of killing a spider is not only a “bad omen” but also harms the home ecosystem. Even the cleanest houses have inhabited spiders. In the journal The Conversation, entomologist Matt Bertone and colleagues at North Carolina State University in the United States published a study of 50 homes in North Carolina and in each home they found spiders. According to Bertone, arachnids are important members of the inner human ecosystem. They are “omnivorous” predators and eat almost anything they catch: from a fly trapped in a window to a mosquito trying to suck human blood. Sometimes, the spiders eat their own kind. A house spider is watching for flies Many of the “victims” of spiders are potential vectors of disease. There is even a species of jumping spider in Africa that only likes to eat blood-sucking insects in the house. So when you kill a spider by hand, you accidentally “kill” a “soldier” to destroy the pathogen in your home. The indoor spiders are not the venomous monster spiders in Australia that we still see in newspapers. During his research, Bertone often found only common indoor spiders like Pholcidae * and the most harmless arthropods of the family Theridiidae **. Both of these spiders spread silk where they live. Spiders Pholcidae sometimes leave their webs to hunt and eat other spiders around. I don’t want to see this scene in my house at all, what about you guys? The truth is that most spiders are poisonous, but the venom of most of them is not strong enough to harm humans. The spider’s fangs are also often too weak to bite through the skin. Hollywood movies have sprinkled us in the head with spiders attacking us while we are off guard. However, in contrast to these movie “myths”, the spiders almost never crawl past a sleeping person. The act of snoring, puffing, or even ordinary human breathing is enough to scare away the vertebrates in the home. Furthermore, spiders are afraid of humans and always try to avoid us. We are far more dangerous to them than they are to us. Cases of spider bites are extremely rare. The scene is haunting for many people Although there are some highly toxic species like the Black Widow, they very rarely bite humans and even so, these bites rarely cause serious medical disorders. If you have phobia or simply don’t want to see spiders crawling around where you live, follow the scientists’ recommendations: instead of killing arthropods, catch them in one. box and drop off the road. The spiders themselves will find a new place and we do not have to carry the “killing” karma. *: Pholcidae are arachnids in the arachnid family of the suborder Araneomorphae. They have a body length of 2–10 mm and their legs can be up to 50 mm long. They can be found on every continent in the world except Antarctica. They weave a messy, irregular mesh. Spider webs are woven in wet and dark areas, in caves and under rocks, and abandoned animal caves. Do these spiders look familiar? Spider webs do not have cohesive properties, but their unusual insect trap structure makes it difficult for prey to escape. Spiders quickly cover their prey with spider webs and then inflict a poisonous bite to kill the prey. The prey can be eaten or stored immediately thereafter. **: Theridiidae is a family of arachnids of the order Araneae. This family has 109 genera, a total of 2295 species. The spider Theridiidae is usually reclusive, almost harmless and extremely gentle.
