How many pixels are contained in one centimeter - it would seem, the question is obvious, there should be no dirty tricks here. But everything is not as simple as it seems at first glance. The fact is that a pixel is not a fixed value - it is the smallest logical element of a two-dimensional raster image that has its own size, transparency, coordinates, color. Therefore, we will take a closer look at these pixel properties and, to solve the problem, we will get acquainted with such concepts as the printer resolution (DPI) and monitor screen resolution (PPI).

After a hard search for services to check the online perfume batch code, I made a list, and I'll share with him in this article. When we buy a product for consumption, we often check the shelf life of the product. As a rule, it is indicated on the bottom of the package or on the side. If we talk about perfumery, then things are different. Most manufacturers (especially foreign) do not put the date of manufacture and shelf life on their goods. Instead, they use the so-called online batch code. Let's see what it is. (Further…)

As you know, progress does not stand still. Science moves forward by leaps and bounds. Judging by the changes that have occurred in the world of technology over the past 50 years, we can confidently say that in this respect, exponential growth is clearly observed. It is even possible that the technological singularity, the onset of which was again actively discussed in 2012 by reputable scientists at the Summit devoted to this topic, soon will not seem just a hypothesis. By the way, even now we are witnessing the development trends of intelligent computer systems, expressed in the gradual complication of neural networks, which are the basis of AI (artificial intelligence), in expanding the range of tasks performed by them. But let's move on to a specific example. (Further…)

PC keyboard is extremely thoughtful in terms of optimizing the use of the device. Here, with a limited number of keys, it was possible to get a huge number of combinations for which one or another action can be fixed programmatically. This is undoubtedly convenient. Notebook makers went even further and added an Fn keyboard to the traditional keys. And the presence of this button can introduce some uncertainty in the work with the device, especially for people who are just starting to master compact PCs. Accidentally or out of habit, touching the key, many users are inconvenienced, and they naturally have a question about disabling the Fn button on a laptop. This will be discussed further.

With the modern pace of city life, ordering a taxi is already a necessity and an integral part of everyday reality. In this segment of the service market, there are quite a lot of offers, however, thanks to the ease of use and high quality, the UBER application stands out. Initially, this mobile application can be installed on a PC, which can facilitate interaction with the UBER service. How to do this will be discussed further.

Brief description of services for compressing video files online; the article also presents an algorithm of actions and principles of operation of video converters. Storing in memory of your smartphone several movies or commercials of its own production has not looked outlandish for a long time. At the same time, many users will agree that no matter how capacious the drive may be, there is always not enough space in the device’s memory. In this regard, the desire to compress video without losing quality online seems quite relevant.
