The biggest difference between Linux and Windows systems

Article Title: The biggest difference between Linux and Windows systems. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

For VPC users, there is not much excitement when upgrading to a new version. This upgrade usually pays for some patch fixes or minor feature upgrades.

Even if you do not consider money, such upgrades may cause a great waste of time, such as backing up files, detaching old versions, and installing new versions. In stark contrast,LinuxUsers expect the upgrade to come just as they expect their birthday. For example, for a new version of KDE or Gnome, the cool new features and user experience are free of charge. And upgradeWindowsWhat's different with the software is that Linux program upgrades are usually handled by the operating system itself.

Linux users can easily wait for the upgrade manager to complete this task. The upgrade time of Linux applications is usually the opportunity for users to relax. Open-source software developers give their users a gift that can bring continuous surprises.

　　1. user-driven is the biggest advantage of Open Source

Dave Roberts, vice president of strategy and market at Vyatta, said, "most open-source projects will launch new versions very quickly. This process is community-driven, and sometimes there are commercial companies involved. Therefore, users often see the expected new features. But it is usually not surprising about the new features. If a developer often discusses with his or her users, it is difficult to keep new features confidential. This process is very transparent ."

For an open-source project, there is usually constant discussion or communication between users and development teams, which will make product users ready to upgrade. In contrast, proprietary software companies develop products driven by their own aspirations, rather than directly engaging users.

It usually takes 12 to 18 months for a new version of Apsara stack to enter the market. Open-source software may see several different version upgrades every month.

In the open-source world, users are closer to development. The upgrade is usually more detailed, said Robert ts. The cost of releasing a new version is much lower. Usually, it is only the address of the new version for users to download. You do not need to burn it into a CD or pack it.

　　Ii. Potential impact of frequent upgrades

Although users usually expect to see more frequent new feature "gifts" in their favorite applications, software developers often have conflicting ideas about this process.

"Frequent release of new versions is a double-edged sword. Software developers have been correcting and patching their applications. On the other hand, developers do not always want to upgrade, "said Barry Klawans, chief technology officer of JasperSoft, one of the founders of Open Solutions Alliance (OSA, "Open-source commercial vendors are usually reluctant to perform such upgrades frequently."

In Linux, the upgrade process is generally considered perfect. In many Linux versions, the upgrade to the operating system is automatically completed by an upgrade manager similar to Microsoft. Software applications can be tracked through the upgrade manager, so that users do not need to do anything except click the OK button and enter the password.

In most Linux distributions, open-source software (often called packages) has been added to the software library by the Community in the required format. The installation script can be automatically processed by the operating system and added to the update Manager program list to automatically check available updates.

However, for application packages from outside the Community software library, you have to manually run the installation script. The initial installation and future upgrade may only be implemented by entering commands in the terminal window. This makes us recall Microsoft's DOS era.

"Some software companies are doing better when handling upgrades, most of which are commercial companies," Klawans said.
