in reply to Nobody Expects the Agile Imposition (Part VI): Architecture

Corrections and useful facts for you.

Windows NT was not a rewrite of Windows 95. In fact it was released in 1993, well before Windows 95 got released.

It is unfair to say that Python 3 has adoption problems. In fact the rate of adoption is slightly ahead of what was initially expected.

There are a lot more successful rewrites you can add to the list. For instance Perl 5 is a rewrite of Perl 4, vim is a rewrite of vi, and less is a rewrite of more.

    Re Windows 95, thanks for the correction, I'll update the root node. It seems that Windows NT was a rewrite of Windows 3 and that Windows 95 was derived from the Windows 3 code base. Update: after two objections, I've now expunged all references to Windows NT in the root node. :)

    Re Python 3, I only claimed it was meeting "substantial resistance". Maybe that's unfair, depending on your interpretation of "substantial", but it's certainly meeting some resistance based on random web chatter on the subject. Well, I'm a Python user and I'm resisting it. ;-) My personal opinion is that breaking backward compatibility was unwarranted for a release with relatively modest improvements. Many businesses with large investments in Python 2.x code will resist Python 3 indefinitely because upgrading will prove too risky and/or too expensive.

    Thanks for the successful rewrite examples; I knew there must be a lot more but didn't spend enough time researching them.

      It seems that Windows NT was a rewrite of Windows 3

      Absolutely not. Windows NT was an entirely separate, new development of 32-bit code. Ie the Win32 API.

      Win32s was a thunked win32 emulation retrofitted to the 16-bit Windows 3.

      In the absence of evidence, opinion is indistinguishable from prejudice.

        Yes I knew that, so maybe I'm using the term "rewrite" imprecisely. To me, it qualifies as a rewrite because Microsoft chose not to adapt the existing Windows 3/95/98 code base for future Windows versions (e.g. Windows XP, Windows Vista) but rather to write a new code base from scratch. How about: Windows NT was a rewrite of the Windows operating system?

        If NT was a re-write of anything, it was a re-write of VMS. ;-)
