這項更新目前已經有測試版可以玩了，正式的版本預計在今年夏天的 Windows 10 年度更新釋出，之後就會在 Windows 10 上面有一個完整的 Ubuntu user space 子細統，不但 Linux 上常見的 utilities 如 grep, sed, awk 等工具未來都可以直接跑在 Windows 10 上，甚至 Debian / Ubuntu 在使用的套件管理系統 apt 也都可以直接使用，不論是對於使用者或是開發者都提供了更大的彈性以及便利性，同時代表未來 Windows 對 Linux 或其他原先只能跑在 unix-like OS 的專案會更加的友善。
ReactOS is a free and open source operating system for x86/AMD64 PSs, based on the best design principles found in the Windows NT architecture, development started in 1996 as Windows 95 clone project, continued as ReactOS in 1998, the goal of ReactOS is “binary compatible with Windows”, that’s awesome, the latest major release – v0.4.0 was announced last month(Feb 2016), it’s about ten years from the previous major release, okay, let’s take a look at the latest ReactOS.
The features of ReactOS:
What’s the difference between ReactOS v0.3.x and v0.4.0? The highlights from the official news – ReactOS 0.4.0 Released:
Looks not so cool if you compare it with some popular operating systems like Windows, FreeBSD, Mac OS X or Ubuntu GNU/Linux, but it’s a huge step of ReactOS, if you would like to take a look at it, ReactOS provides live CD iso image, you can also install it by yourself, or download pre-installed VirtualBox/VMware image, I’ll use live CD in VirtualBox virtual machine to demonstrate ReactOS as below.
The size of zipped file(ReactOS-0.4.0-live.zip) is about 66MB, the size of the extract iso file(ReactOS-0.4.0-Live.iso) is about 198MB, compare to currently popular operating systems, it’s really tiny!
This is the first screen of ReactOS, the boot menu, there are 4 options here, but there isn’t significant difference for end-users, the most different thing may be the booting progress will be shown during the process:
For Firefox, open the link below: about:config and click “I’ll be careful, I promise!“, and find network.dnsCacheExpiration, set its value to 0 (create one if it didn’t exist). Now the cache should be flushed, and set network.dnsCacheExpiration back to 3600, or you the cache will not work at all.
Operating system level:
Windows: ipconfig /flushdns
Linux: Depends on the dns service: sudo /etc/init.d/dns-clean restart sudo /etc/init.d/nscd restart sudo /etc/init.d/dnsmasq restart /etc/init.d/named restart
