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.

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.

Update: Even a company as wealthy as Google, as of 2017, are still heavily using Python 2. This is hardly surprising. Where is the ROI on spending millions of dollars rewriting millions of lines of already working code, without adding any customer value, while being almost guaranteed to suffer numerous breakages to critical business systems? You also pay an Opportunity cost. Curiously, I see some of Google's legacy Python 2 systems are being rewritten in Go perhaps because at least there is some perceived customer value (faster performance) in a Go rewrite. For smaller less wealthy companies, rewriting millions of lines of working Python 2 code in Python 3 could well put them out of business. Of course, if you don't have much Python 2 code, switching to Python 3 is a no brainer. Further update: I see Jython is still Python 2 in 2020 and IronPython3 unfinished. At least Perl doesn't have to worry about updating Java and CLR versions of the language. :)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
