Generally, the android applications we develop are based on activity and the Android system manages the life cycle of the program. However, sometimes we also want to control the process of the Program on our own. For example, if you only develop a console application like/system/bin/PM, it is not appropriate to use activity. Here I call this self-controlled process as a standalone Android program.
There is no big difference between the development me

1. What is mahout?
Mahout is an open-source project (http://mahout.apache.org/) of Apache that provides several classic algorithms in the machine learning field, allowing developers to quickly build machine learning and data mining applications.
Mahout is based on hadoop. The name is also very interesting. hadoop is the name of an elephant, while mahout is like a husband and a viewer. It can be seen that the two are closely related. (This naturally reminds me of sun and eclipse ...)

Ii. Kafka performance bottleneck
When Kafka is integrated with storm, the data processing performance is not very good and does not meet the expected requirements. I initially suspected that it was a kafkaspout code problem, but storm external has included it. I don't think the problem is here. Then, let's take a look at kafkaspout implementation and find possible performance bottlenecks. To increase
Install and use Git standalone version
Introduction:
Git is an open-source distributed version control system. It is one of the most popular and advanced version control software today.Git is a distributed version control system. On the contrary, SVN is a centralized version control system. Each time SVN changes a file, it must be submitted to the server for storage, and Git has a complete local version library.

$ export DISPLAY =: 0.0 // This is the case for installing on the local machine. If it is on another terminal, change it to export DISPLAY = ip: 0.0, this is because 127.0.0.1 of the local machine is omitted.
3. Execute the graphical interface installation steps:
Step 1: do not check the check box, do not fill in the email, directly go to the next step, ignore the pop-up warning box (no email warning is provided)

Oracle standalone environment enables automatic database startup upon startup
In both Windows and Unix environments, Oracle databases can be automatically started.
In Windows:
The experiment method is relatively simple. It can be implemented by modifying the registry or using the oradim command:
Oradim-edit
In Unix:
Experiment with the dbstart command that comes with the database.
Command: dbstart + {full path of ORACLE_HOME}
