CTOnews.com, October 26 (Xinhua) legendary engineer David Cutler (David Cutler) recently gave a 9-minute video interview to review the development of the Windows Longhorn system and confess that the code written by the system was "the worst he has ever seen."

CTOnews.com Note: Gates recruited him to Microsoft in 1988 and spent five years at a cost of $150 million, leading more than 200 engineers to develop Windows NT with 4.3 million lines of code.

Its technological revolution has seriously impacted the status of Novell's Netware and UNIX operating systems, brought inestimable business value to Microsoft, and affected the computing experience of more than 2 billion people.

As a result, he has so far become the only engineer to enjoy the title of Microsoft Senior Technical Fellow, equal to that of the group VP. Ballmer, the former CEO of Microsoft, said bluntly that without him, there would be no Microsoft today.

Windows LonghornWindows Longhorn may be unfamiliar to many people. It is the system code developed by Microsoft in 2003-2005 and hopes to be the successor of WinXP system.

Microsoft initially only wanted to build Windows Longhorn into an incremental updated version of WinXP, but then the code got out of control and its scope exceeded the company's expectations.

Microsoft then decided to make it the next major version of WinXP and officially release it in the form of Windows Vista.

What did it go through when developing Windows Longhorn? host David William said in an interview that Windows Longhorn was called "the pioneer of Windows Vista".

"there's a big story behind it," Cutler said later.

He said that after completing the Win2000 system, the development team began to prepare plans for the next generation of operating systems, hoping that workstations and servers would use the same code base.

Chris Jones is responsible for developing its workstation, while Dave Thompson Group is responsible for the server side. At the time, the team revealed that it would take three years for the server to run and successfully debug the next generation system, and Cutler could not accept such a long time and demanded that the goal be achieved within a year and a half.

This leads the development team to split the code base in two, with one team responsible for the server and the other responsible for the consumer vision.

Cutler acknowledges that the consumer sector has encountered some obstacles in the process, saying it is almost impossible to run. Although the server branch has made significant progress in development, some security bugs have been fixed.

Although there were some software development problems with the launch of WinXP, Windows XP was finally delivered to consumers. In the words of Cutler, "it has achieved widespread success, but it also has defects." The biggest problem affecting the operating system is mainly focused on security.

He further revealed that the development team used Windows XP's code base for Windows Longhorn, which was released in the form of Windows Vista.

Cutler, the rise of 64-bit code, recalls that when AMD presented him with the potential idea of a 64-bit extension, he claimed that it was "less intrusive" and could run 32-bit applications quickly on 64-bit machines.

Cutler decided to try the project, which eventually led him to use the server code base to produce 64-bit workstations and 64-bit servers.

At this point, the team discovered the reliability of the new system, which prompted them to try to persuade Microsoft.com to transition to a 64-bit server. The site took only a week to complete the transition, while the 32-bit processor previously used had a number of errors such as memory leaks.

Later, the development team turned to the 64-bit code base because all their previous efforts to develop the operating system turned out to be futile. However, due to the deteriorating security of Windows XP, the progress of the project has stalled.

Cutler says his team alone fixed more than 5000 bugs and handed over some of the system code.

Cutler said that Windows Longhorn showed him the worst code, and some of the IME code could not even be fixed.
