2 nanopi-neo--First Experience In the last section we introduced Nanopi Neo's appearance, resources, interface, etc., is not full of expectations of Neo. Without further ado, let's have a quick experience. Figure 1.4 Nanopi NEO v1.3 Open box Check Because Neo is started with an SD card, we need a microSD card/TF card with a running system, the system used for t

Npi-config is a command line system Configuration Tool under our Nanopi-neo system that allows you to perform some initialization configuration of the system, including user passwords, system languages, time zones, Hostname, SSH switches, automatic login options, and more. You can enter at the command line by executing the following command: sudo npi-config The npi-config display interface looks like this: Figure 1.17 The display interface of the Sys

1, Introduction--From the wiki interpretation/dev/null:In a Unix-like system, a/dev/null, or empty device, is a special device file that discards everything written to it (but reports a successful write operation) and reads it immediately to get an EOF.In programmer jargon, especially in Unix jargon,/dev/null is called a bit bucket or black hole. Empty devices are often used to discard unwanted output streams, or as empty files for input streams. These operations are usually done by redirection.

If the polygon is not self-Intersecting, you can simply determine whether the point is inside or outside the polygon. If the polygon is self-Intersecting, therefore, it must be determined based on the non-

Recently, in order to process the source code of html files, regular searches and replacement are required. So I took this opportunity to learn about the regular expression system. Although I used regular expressions before, I learned how to get through them temporarily. In the course of learning, I still encountered many problems, especially the zero-width assertion (I want to talk about it here. The content copied and pasted on the internet is every

Non-zero-point clustering, zero-point Clustering In a binary image, clustering is performed between non-zero points. When a rectangle frame is used to mark its region, overlapping areas and nesting between adjacent rectangular frames are mainly solved. For reference only.
