Should I use a standard video editor? Windows movie maker

When a large amount of diverse video material is accumulated on the computer of an ordinary user, a definite desire arises (especially given the existence of the Internet and many social networks in it) to share it with as many people as possible.

Home video material such as filming holidays, hiking and other events is calmly laid out on the same YouTube video hosting, some more special shootings can be used to create a variety of video reviews, video blogs and similar Internet hobbies. In any case, the video material that should be posted on the Web often needs some work – if not color correction, then at least cropping unsuccessful fragments.

How much did the first personal computer cost?

I must say that April 1 was a suitable day for the birth of a company that was going to do business at that time not at all serious, namely the sale of personal computers. In 1976, in the United States, this business seemed highly dubious. Who could be interested in personal computers at that time? Only crazy hams. For them, parts were sold in the store, from which the Altair 8800 home computer could be assembled without special difficulties. Those who did not want to bother with a soldering iron and with a setting could ask the seller in the store to assemble it for a small additional fee.

Fools! Stupid kids! Continue reading

What is Rear Admiral Grace Hopper famous for?

Grace Hopper was an excellent mathematician and one of the first “encoders”, so-called programmers. In the mid-twentieth century, she, as an officer of the US Navy, like everyone who was “close” to computers, worked at Harvard in the department that was engaged in obtaining ballistic tables for artillery tasks.

So Grace Hopper is considered one of the first programmers in the world: she worked on the computer of Mark I, the former, in fact, a giant calculator. The giant Mark I was intended for the computational processes of obtaining artillery ballistic tables, in the already written algorithm, mathematical tasks (modules) of a general nature were provided. Hopper and her colleagues (by the way, there were much more female programmers involved in coding than men) coped with this – they first applied Continue reading
