Uzi maalum wa kupeana Likes: Comment chochote upate "Like"

Watu wengi wanahifadhi data zao mtandaoni, kitu amabacho ni bure na kimejipatia umaarufu zaidi hivi karibuni. Hifadhi hii ni kama vile iko hewani, hifadhi-pepe, sehemu ambapo mtu hajui iliko ila anaamini ipo na ipo salama. Unaweza kupata hifadhi hii ya bure, kwenye simu au kompyuta yako.
 
735. Why do Wheels Sometimes Appear To Spin Backwards?

This phenomenon is known as the "Wagon - Wheel" effect. So when a wheel seems to spin in a direction opposite it's actual rotation, it's because each spoke has come up a few degrees shy of the position it occupied when it was last imaged by the camera or with human eye. This is sometimes reffered to as the reverse-rotation effect.

[emoji117] Steam Engine (Piston), 1712. Inventor : Thomas Newcomen (England) (1663-1729).

Kuna kampuni nyingi za hifadhi-pepe ambazo zinatoa huduma kulingana na mahitaji ya mteja ila wengi wanalenga mtumiaji wa kawaida na hutoa huduma hii bure, kwa kiasi kidogo. Kampuni hizo ni kama Dropbox, Box na makampuni kinara ya Microsoft, Google na Apple.
 
Teknolojia ya uhifadhi kidigitali imekuwa ya gharama nafuu sana na kampuni hizi zina imani kwamba watu wa kawaida wakizoeshwa kutumia huduma hii ya bure, watu haohao watatamani kulipia kwa huduma zaidi na pia watashawishika kuitumia huduma hii kwenye biashara zao au makampuni wanayofanyia kazi.
 
734. What is dandruff?

Dandruff is a very small piece of dead skin and it can have several causes, including dry skin, seborrhoeic dermatitis, not cleaning/scrubbing often enough, shampooing too often, scalp psoriasis, eczema, sensitivity to hair care products, or a yeast-like fungus. Dry skin is the most common cause of flaking dandruff.
 
733. Why doesn't Glue Stick to its container?

That strong smell that comes out when we open the tube's cap is due to the solvents evaporation, so once they're gone the glue sticks. If a superglue tube is left open for a long time (exposed to air, allowing the water to come in contact with the glue), it's impossible (or almost) to squeeze it out and therefore sticks to the container. You may have noticed that super glue tends to dry out in its container more quickly than white glue. Super glue works differently than white glue. Instead of the polymers in white glue, super glue is made of a chemical called cyanoacrylate. This chemical bonds things together when it reacts with water vapor in the air.
 
731. Why do wines get aged in oak barrels?

Oak offers three major contributions to wine:

It adds flavor compounds–including aromas of vanilla, clove, smoke and coconut.
It allows the slow ingress of oxygen–a process which makes wine taste smoother and less astringent.
It provides a suitable environment for certain metabolic reactions to occur (specifically Malolactic Fermentation)–which makes wines taste creamier.

Faida kwa kwako, mtumiaji
Mambo yanavyozidi kwenda kidigitali na watu nao wanabadili jinsi wanavyofanya hayo mambo – kidigitali. Siku hizi, mtu anapendelea zaidi kuhifadhi mafaili yake kwenye hifadhi-pepe ili aweze kuyapata popote alipo.
