设置文件属性与权限
三个常用的修改权限命令：chown修改文件属主，属组
chgrp修改文件属组
chmod修改文件权限

例使用chown命令修改文件的属主从root改为Ybaci

修改属主的同时修改属组，在属主与属组之间加入“.”即可

只需要更改文件的属组而不需要更改属主，使用chgrp命令

修改文件权限使用chmod命令
给该属组增加执行权限，当查看属组权限字符位出现“x”，说明增加执行权成功 chmod u+x

给该属组增加写入权限，当查看属组权限字符位出现“w”，说明增加执行权成功 chmod g+w

同时给所有对象增加读，写，执行权限，在chmod命令后加“a”符号，然后覆盖当前全部权限
chmod a=rwx file

同时给所有对象删除某一个权限 chmod a-x
同时删除所有对象的全部权限 chmod a=- file

chown：将某个资源的访问权限给予别人
chmod：改变某个文件的访问模式与命令

Supervised and Unsupervised learning in machine learning

Machine learning is a subject of artificial intelligence, which means programming computers in terms of algorithm so that they can learn from data. Supervised learning and unsupervised learning are two types of Machine Learning systems. One can easily tell the difference between them by the criterion: whether or not they are trained with human supervision. Supervised learning and unsupervised learning are two extreme. The former completely depends on human supervision, while the latter doesn't n ...

AI: Deep Learning vs Machine Learning

In the previous article Supervised and Unsupervised learning in machine learning, we explains the meaning of machine learning. As AI is making waves across industries, we often hear the terms "deep learning" and "machine learning" getting thrown around interchangeably. While both are crucial for AI advancements, they are indeed two different subjects with distinct characteristics. Deep learning is a branch of machine learning, whose methods are based on artificial neural networks (ANNs). In othe ...

Django use icontains with in for field lookup

In Django, __icontains and __in are field lookups to the QuerySet methods. __icontains is a case-insensitive containment test, and __in means that the field is in a given iterable. So I would like to do the following lookup:keywords = ['How', 'to', 'setup', 'PrismJS', 'and', 'Autoloader', 'plugin', 'with', 'Nuxt', '3?'] #Possible keywords of title Writings.objects.filter(title__icontains__in=arr)Unfortunately, we can not combine field lookups in Django. To implement our desire, we can use Q() ob ...
