Guido van Rossum Leaves Zope.com

VladDrac writes "Guido van Rossum, the author of the Python programming language, announced at OSCON last night that he's leaving zope.com, to work for a new startup called 'Elemental Security', founded by Dan Farmer (known from several security tools such as Satan). Guido leaving Zope.com will also probably mean that he will be no longer involved in Zope3 development, but hopefully he'll have more time to spend on Python development." Guido says that he's excited about his new employer, but that nothing substantial will change about Python as a result of the move. "It's just that I'll be working from the West coast." Python is "already quite secure," he says, and will be the basis of an upcoming security product ("just getting started") from Elemental.

    No doubt he'll have much more time to dedicate to his programming. Python sounds pretty interesting, and I dug through the BitTorrent source a bit to learn more about it, but it also seems pretty complex for what the end result is (as opposed to, say, Perl.) With a bit of work towards a more logical parse tree/DTD, I could see Python easily surpassing Perl as a strongly-typed effective scripting language.

      Python is actually simpler than Perl -- it's designed to be so. HOWEVER, Perl is also designed to do many specific things very simply, so when you need to do one of those specific things it's the fastest way to get it done -- assuming, of course, that you already knew Perl could do it :-).

      I'm a Python fan, but I doubt Python will ever surpass Perl -- especially not by adding a "more logical parse tree", since it already has a very simple, consistent, and logical parse tree whereas Perl has more of a parse forest. Python and Perl are just too different; they compete in many areas, but their real strengths are far enough apart to keep them both viable in each other's presence.

      It is a misconception that Python is not strongly typed. It is strongly typed, it is not *statically* typed.

      Python is a stronly typed, dynamically typed, extremely late bound language.

      Double check your facts before calling someone else a dumbass.

      The difference between a dynamically typed language and a statically typed language is this:
      // Java
      int myvar = 1;

      # Python
      myvar = 1

      The difference is that the Java compiler assigns a datatype to the location of myvar, but python assigns a datatype to the value held in myvar.

      It's a subtle difference, and many python newbies think it's not strongly typed, however that is a mistake.

      Guido seems to disagree.

      GvR: In a strongly typed language, when you change to a different data structure, you will likely have to change the argument and return types of many methods that just pass these things on. You may also have to change the number of arguments, because suddenly you pass the information as two or three parts instead of one. In Python, if you change the type of something, most likely pieces of code that only pass that something around and don't use it directly don't have to change at all.

      Now you might be splitting hairs and saying that "static" means known at compile time and "strong" means type errors are always detected, but in common parlance "strong typing" includes static typing. For the pedants, there's Sebesta:

      ...we define a programming language to be strongly typed if type errors are always detected. This requires that the types of all operands can be determined, either at compile time or at run time.

      This criterion is met by very few real-world languages. Most imperative and object-oriented languages include type coercion which contradicts this property. It is interesting to note that future Python development is moving towards still stronger typing -- and, dare I say it -- functional-style constructs.

      Of course, the pragmatic thing to do is to understand strong/weak typing not as binary, but as a continuum. In this case, Haskell is more strongly typed than Ada is more strongly typed than Python is more strongly typed than C++ is more strongly typed than C is more strongly typed than FORTRAN. It looks like Python 3.0 will be moving up the chain, however.

    Dear Zope 3 developers,

    Last night at OSCON I announced that I am moving to California. I
    have accepted a new job at Elemental Security, a security software
    startup in San Mateo. You may have heard of one of the founders, Dan
    Farmer, who is the (co-)author of several well-known free security
    checking programs: Satan, Titan and The Coroner's Toolkit.

    Elemental is a brand new company, and I can't say much yet about the
    product, except that it will be aimed at enterprise security and use
    Python. I'm very excited about working with Dan on its design and
    implementation.

    I'm also excited about moving to California, which has long been a
    dream of mine. I'm looking forward to getting together with the many
    local Python users and developers once I'm settled; right now, my life
    and that if my family is total chaos because we're trying to find a
    home and move into it by August 1st.

    I will still have time for Python (it's in my contract) and I will
    continue to lead Python's development. The other PythonLabs folks:
    Fred Drake, Jeremy Hylton, Barry Warsaw and Tim Peters, are staying at
    Zope, by the way.

    But unfortunately, this move pretty much ends my involvement in Zope
    3. I've signed a contributors agreement, but with the new job and my
    Python work I don't expect to have much time for Zope. So this is
    also a goodbye, of sorts. I've enjoyed working with many of you, Zope
    3 developers, and I expect we'll run into each other at some future
    Python event.

    In the mean time, I'm here at OSCON with a busy schedule and limited
    access to my email, and the following weeks I will be in transition,
    so please be kind if I don't reply immediate when you write me.

    That's funny. I switched from Perl to Python several years ago and one of the things that I like best about Python is the documentation. Perl's Camel book made a pretty fair reference, but I didn't really like busting out a hard-copy book every time I wanted to look something up. The electronic Perl documentation was pretty nice, but it wasn't quite as comprehensive as the Camel book, and the POD format simply can't compete with Python's documentation. The PDF and HTML formats are nice, but I really like the fact that the Python documentation is available in info format for easy reading in Emacs (complete with a comprehensive index). The indexes in Python's electronic documentation really make a heck of a difference once you start using them. Perl's pile o' man pages simply can't touch Python in this regard (IMHO).

    Perl's TIMTOWTDI style means that every time you edit someone else's Perl code you will encounter four or five new Perlisms that you have never seen and that require the Camel book for deciphering. When I was hacking Perl, that meant carring around the Camel book in my laptop bag "just in case." With Python that's no longer a problem.

    My guess is that you have gotten use to the structure of Perl's documentation. You know where to find Perl information, and are simply frustrated by the fact that Python requires that you start from scratch with a new set of documentation.

    On the other hand, it is possible that we simply have different documentation requirements. What precisely is the problem? "They suck," is not particularly descriptive.

    Since this last one is particularly telling, I will quote the relevant text for our impatient readers:

    I think Guido's rationale for removing all these features will be widely misunderstood. Me channeling him: it is not that he believes that the architectures developed were inherently incapable of providing security. Instead, he feels that no "expert" for these matters has reviewed these architecture for flaws, and that the continuing maintenance of these things isn't going to happen.

    If this understanding is correct, then any new approaches will likely suffer from the same fate. Unless somebody steps forward and says: "I am a security expert, and I guarantee that this and that feature is secure (in some documented sense)", then I think he will dislike any changes that mean to provide security.

    So this not a matter of engineering but of authority. Somebody must take the blame, and Guido doesn't want to be that someone.

    Disclaimer: I love python. However, I am working on a project that depends on rexec, and when I discovered that it was being removed, I was a little annoyed - especially at the reasoning behind the decision.

It features an object database that, for example, lets you create an image object, and then call it from other code to automatically build your image tag based on the dimensions and title of the image stored in the object.

    It's open source, developed both by the Zope community and the Zope corporation. There are at least two kick ass, open source content management systems built on top of Zope Corp's content management framework that I know of: Plone and Silva. There are a ton of add-on products that are downloadable too.

    Zope does have a pretty steep learning curve, if you don't do stuff with "real" web applications (stuff that needs access control lists, user management, templating, etc) it might not be right for you, but it's great for bigger applications.

The rest of the documentation is a mish-mash of user-written howto's, some of which are excellent, some of which are dupes of others, many of which are out of date, and others of which are just badly written. Searching the database of these is hard, and it's very difficult to distinguish well written old ones that are still relevant from newer ones that aren't very useful.

    My main problem with it though is that although it focuses hugely on the differences between zope development and regular web development without seriously dealing with implementation examples of common tasks. On and off it took me about a month to figure out how to make a simple form-based login system (similar to slashdot's) and tie it into Zope's user folder system. Co-incidentally The only zope-based website I could find that actually did this was zope.org itself.
