Any material on any site wins, provided it is illustrated with photographs, drawings, diagrams and other graphic files. And if the size of these files does not matter when typesetting the material on a modern computer equipped with gigabytes of RAM and hundreds of gigabytes of space on the hard drive, then when publishing on the Internet the situation changes.
In our country, only a few of the largest cities can boast the availability of high-speed unlimited Internet. The province still sits tightly on modem communications, and the backwoods even on GPRS (communication using a mobile phone). The data transfer rates on these channels are depressingly low, so large web pages load annoyingly slowly. Since image files are champions in their place, you should reduce them as much as possible with the selected quality standard. How to do it in a few Continue reading
In the first part of the article, we examined the concept of a platform for a blog and found out that there are two ways to create a blog. The first way (how to create a blog on a free blog service) we have already figured out. Consider the second method. How to create a blog on a paid hosting? First, you need to choose a free “engine” for your blog, it is also called CMS (you can, of course, order it from programmers, but this is an additional cost, and we are considering options with minimal losses). Then you need to choose an inexpensive high-quality hosting, on which we will register the selected domain name and post a blog. This is the first and most important step in creating a blog on a paid hosting. Here, as it might seem at first glance, everything is complicated. I assure you Continue reading
In historical terms, the radio appeared recently, only about 100 years ago. However, during this time, technology has changed dramatically – from spark transmitters Popov and Marconi to modern handheld FM transmitters with an SD card. But no less interesting is that now broadcasting technologies are at a new round of development, perhaps even more significant. It is possible that after another 100 years (and maybe earlier), turning on the grandfather’s receiver, you won’t be able to catch anything at all, since the broadcasting standards will be completely different. However, first things first. Some technologies already used in the latest generation of radio receivers will be discussed in this article. Direct-sampling, or “direct digitization” This technology has appeared relatively recently, but its prospects are enormous. As you know, radio waves are electromagnetic waves of different frequencies. In the simplest case, the input circuit of the receiver is an oscillating circuit tuned to the Continue reading
