Of course, it's just not accurate to imply that Java had nothing to offer: in an age when a number of languages provided support for safe execution (Obliq, Telescript, Safe-Tcl, etc.) and where a few had in-built support for concurrency (Ada, Occam, etc.), Java rather effectively brought both of these and more to the mainstream. It may be true that the language didn't justify the hype and that the API was fairly badly designed in various places, but it represented a step up for most developers, and the hype managed to give many of those developers a chance or an excuse to use the language, rather than be forbidden to use it because it didn't fit in with corporate or organisational strategy. There are parallels with Rails in the Java hype story: something better than what lots of people are using (probably PHP in most cases), combined with a dose of hype to persuade decision makers that everyone else in the herd is moving in that direction, leads to something suddenly becoming popular, being perceived as the next big thing, and having lots of vocal evangelists who might seem like wise men to the masses, but whose pronouncements on dynamic languages, for example, seem belated and obvious to many of us.

What do you know fool chicken crosses road Elapsed: 2.278332 seconds It seems the unification of the strings via hash is not significantly better (compared to memcpy or whatever is used). The results for the dinkumware STL are dominated by the sheer number of calls to HeapAlloc/HeapFree and to EnterCriticalSection/LeaveCriticalSection (I compiled with multithreading and linked statically). The python version won't be concerned with the latter, I guess (although just by importing 'threading' performance gets about 3.5% worse). STLport uses for example InterlockedExchange (obviously in the default allocator) and several orders of magnitude fewer calls to the heap allocation API. It all boils down to the fact that I can write C++ or even assembler programs that perform worse (by any degree I want) than a functionally equivalent python program. That's a trivial insight and it certainly doesn't provide evidence that python 'is faster' than c++/assembler. Even if that's just because it *isn't* and can't be. I always wonder where this rage comes from to prove oneself or whomever that python is the best programming language in any regard as if it hadn't enough other advantages. It is certainly not the fastest/most memory efficient tool out there. One of the biggest advantages of python to me is that, even if I run into a hotspot, the transition from python to C/C++ is so easy. That means that in spite of its warts (GIL, memory efficiency ...) I don't easily come to a dead end using python. This fact lets me use python's great strengths (like programmer efficiency etc.) without tossing and turning sleeplessly in my bed. cheers, aa -- Andreas Ames | Programmer | Comergo GmbH | Voice: +49 69 7505 3213 | ames AT avaya DOT com -- http://mail.python.org/mailman/listinfo/python-list

All-in-all, Ruby is mostly as good as Python in most ways and better than Python in a couple key ways. The big difference between Ruby and Python is the lifecycle phase that the languages/systems are in: Ruby arguably has room for a lot of basic improvements in the architecture of the virtual machine and presumably has a list of must add features that cover gaping holes with respect to certain audiences [1], whereas Python has been around for ages and has covered most of the critical gaps in the feature list (although we can always suggest things which bother our own part of the community). Whereas the Ruby people merely have to agree on how critical their missing features are and to move in one widely agreed direction, the Python people face a tougher choice as to what should be done next; strategies include a tidying-up exercise to make the language more coherent, a complete reimplementation, deep modifications to the runtime, the introduction of radical new semantics. The fewer obvious issues that a language has, the less energy there is in the community to deal with those issues thoroughly, I think. I guess the Perl community chose a bold new direction in line with the observation that a big vision can inspire much more in people than lots of incremental changes to an existing vision, but the energy required to follow through on such a vision can be immense. In addition to all this, a large existing community is more likely to want larger benefits for smaller levels of disruption because of the amount of existing code. Thus, the available energy for change is less in a mature project than in a growing project because people have to constantly monitor the breakage in their existing investments in the language. ...but you can't READ Ruby code. Yeah, that's one of the big reasons I haven't seriously considered trying it. It's expressive, got interesting features... and appears unreadable to me. I'm usually pretty good at deciphering most languages, even if I haven't used them before, but Ruby is one of the exceptions. My feeling is that I'd rather learn more about Lisp or Scheme than Ruby - the benefits are greater and for me Lisp and Scheme increasingly have the edge on readability. Perhaps I'm just not tuned in to Smalltalk-style syntaxes. This brings us back around to the web framework debates. For many people Ruby fits their brains and for others Python does. I think frameworks are similar. I tried Django and while I thought it was a great product, it simply didn't fit how I think about that problem domain. I thought that the most interesting thing about Django was the URL mapping strategy it employs, although you have to be fond of regular expressions to really appreciate it, I think. The template and persistence mechanisms used have the principal advantage of just being there in the same package when compared with other solutions, and I don't think they'd have many fans if they were just some random projects available from the Python Package Index. TurboGears on the other hand did, and really, it helped clarify a few things I had vague notions about. I think we'll do better not trying to shoehorn people into one or the other. The goal is to provide appropriate solutions for particular problem cases, especially common cases like database-backed Web sites, rather than choosing something which only does a particular flavour of database-backed site and then claiming that it's a silver bullet. I've written a number of Web applications for my own use, and many such applications either don't use a relational database or use it in a way that is completely orthogonal to some relatively simple object-relational scheme. Some of these applications are admittedly simple, but having to create various tables in relational databases as an offering to some framework deity is pure unnecessary overhead that should suggest, at least to the more objective among us, that any solution requiring such baggage is perhaps not always the most optimal.

This project is multilangual and free it is called EuroCv and it need a module for exporting data in PDF. A brute-force approach could be to sidestep PDF and design a template(s) in LaTex containing fields identified by strings. LaTeX can produce many formats, one of those is PDF. Then have your output module read the template, do a search replace of the fields with values (remembering to quote the characters that LaTex will choke on and removing the codes for the blank fields) and write the finished LaTeX document to disk. (Maybe there are even templating modules in Python that will take care of this). Then compile the documents with latex, run the resulting *.dvi file through dvipdf and return a link to it. This is a compiler pattern. You need a naming scheme to identify your file(s) but the rest is pretty old. The Python application scons (a make replacement) can control the build process - in case that you are not on a unix box - one could have build application periodically looking for *.tex files and compile them into *pdf whenever one is deposited in the right place.

The sysadmin already set the setuid bit on the script, but it still fails when it tries to write to any file that only root has write access to. I read somewhere that any scripts that start with #! will no honour the setuid bit... I also tried os.setuid(0), with the setuid bit on, but this call failed. I am now out of ideas :( Any sugestions?

[ANN]UliPad 3.3 is released
What's it?
It's an Editor based on wxPython. NewEdit is the old name, and UliPad
is the new name. UliPad uses Mixin and Plugin technique as its
architecture. Most of its classes can be extended via mixin and plugin
components, and finally become an integrity class at
creating the instance. So UliPad is very dynamic. You can write the
new features in new files, and hardly need to modify the existing
code. And if you want to extend the existing classes, you could write
mixins and plugins, and this will be bound to the target class that I
call Slot Class. This technique will make the changes centralized
and easily managed.
What are its features?
* Cross platform
o based on wxPython, so it can run anywhere that wxPython
works, such as: Windows, Linux.
o Unicode support.
* Most features of wxStyledTextCtrl(Scintilla)
o Syntax highlighting, support Python, c/c++, html, plain
text, perl, ruby, css, javascript
o Folding
o Brace Matching
o ...
* Extended selection
o Extended word selection -- You can press
Ctrl+MouseDoubleClick to select a word including '.'
o Matched selection -- Select text in quoted chars like:
(), [], {}, '', .
* Other editing extension
o Duplicating text -- Just like Vim Ctrl+V, Ctrl+P, and
more. You can duplicate above or below char, word, line
o Quoting text -- Add some quoted chars before and after
selected text, just as: , '', (), [], {}, and
o Text convertion and view -- python - html, reStructured
Text - html, textile - html, and you can output or view
o Utf-8 encoding auto detect
o Changing document encoding
oAuto backup
oLast session support -- It'll save all the filenames as
closed, and reopen the files as next started.
oSmart judge the indent char -- It'll auto guess the
indent char, and sets it.
oFinding in files
oBookmark support
* Python support
obuilt-in python interactive window based on ?PyShell,
support Unicode
o Auto completion
o Function syntax calltips
o Run, run with argument, stop python source
o Auto change current path
o Python class browser
o Indent pasting support(New)
* Code snippets
o You can manage your code snippets with categories, and
each category can have many items. Every item will represent a code
snippet. You can insert an item just by double-clicking on it. It even
supports importing and exporting.
* Simple project support
o Can create a special file _project, so every file and
folder under the folder which has the _project can be considered as a
whole project.
* Extension mechanism
o Script -- You can write easy script to manipulate the all
resource of UliPad, just like: text conversion, etc.
o Plugin -- Customized function. More complex but more
powerful. Can easily merge with UliPad, and can be managed via menu.
o Shell command -- Add often used shell commands, and execute them.
* Ftp support
o You can edit remote files through ftp. You can add,
rename, delete, upload, download file/directory.
* Multilanguage support
o Currently supports two languages: English and Chinese,
which can be auto-detected.
* Shipped plugins(must be configed as used them before)
o Document links -- Python documentation and wxPython documentation.
o Many plugins can be found at UliPad wiki page.
* Shipped scripts
o Many scripts can be found at UliPad wiki page.
* Wizard (New)
o You can make your own wizard template. The wizard can
input user data, combine with template, and output the result. And
wizard also support code framework created. This feature will help you
improving coding efficiency.
* Direcotry Browser(New)
o Browse multiple directories, and you can really add,
delete, rename directories and files. Double click will open the file
in Editor window.
o Support Copy, Cut, and Paste.
o Search in Directory
* AutoComPlete(acp)(New)
o Suport user autocomplete file, it can help to input code
very helpful and functional. Just like EditPlus, but may be more
powerful.
o Manually apply some acp files to current document
* Column Edit Mode(New)
Where to download it?

Well that's great, but how do you access the ini file portably?
From my original post:

Thanks, but where in the directory structure do you put the ini file on
different platforms? Presumably you have to hard-code that into the source
and then do operating system type detection?
i.e. if I make my config parser:
import ConfigParser
config = ConfigParser.ConfigParser()
config.read(filename)
What do you use for filename on Windows? What on Linux? OSX? etc. How do
you detect which operating system you are running on?
Tom
I almost always have the .ini configuration file live in the same
directory/folder as the program or sometimes in a subdirectory of
the install directory (which I reference relative to where the
program is run from). Typically I install a default .ini file
via program installer (I like Inno Installer on Windows). I also
make all my programs accept a -i configuration file path argument
when they are run so you can override the default .ini file on the
command line.
example:
myprog -i C:\aaa\bbb\myprog.ini
As a default I do config.read('myprog.ini') it always reads from
the current directory (which is where the program is installed).
To access a subdirectory of the current directory I do something
like:
p=os.path.join(os.getcwd(), 'configfiles')
config.read(p)
I haven't put anything on OSX but this works fine on Windows
and Linux and should work on OSX.

Then have your output module read the template, do a search replace of the fields with values (remembering to quote the characters that LaTex will choke on and removing the codes for the blank fields) and write the finished LaTeX document to disk.

This is a compiler pattern. You need a naming scheme to identify your file(s) but the rest is pretty old. The Python application scons (a make replacement) can control the build process - in case that you are not on a unix box - one could have build application periodically looking for *.tex files and compile them into *pdf whenever one is deposited in the right place.

Re: sum and strings
Just because something is slow or sub-optimal doesn't mean it should be an error. that's not an error because it would be slow or sub-optimal to add custom objects, that's an error because you don't understand how sum works. (hint: sum != reduce) No, clearly sum!=reduce...no dispute there... so we go ahead and get the sum([q1,q2]) working by specifying a starting value sum([q1,q2], Q()): class Q(object): ... def __init__(self, n=0, i=0,j=0,k=0): ... self.n = n ... self.i = i ... self.j = j ... self.k = k ... def __add__(self, other): ... return Q(self.n+other.n, ... self.i+other.i, ... self.j+other.j, ... self.k+other.k) ... def __repr__(self): ... return Q(%i,%i,%i,%i) % ( ... self.n, ... self.i, ... self.j, ... self.k) ... q1 = Q(1,2,3,5) q2 = Q(7,11,13,17) q1+q2 Q(8,13,16,22) sum([q1,q2]) Traceback (most recent call last): File stdin, line 1, in ? TypeError: unsupported operand type(s) for +: 'int' and 'Q' sum([q1,q2], Q()) Q(8,13,16,22) Thus, sum seems to work just fine for objects containing an __add__ method. However, strings contain an __add__ method. hasattr(, __add__) True yet, using the same pattern... sum([hello, world], ) Traceback (most recent call last): File stdin, line 1, in ? TypeError: sum() can't sum strings [use ''.join(seq) instead] Which seems like an arbitrary prejudice against strings...flying in the face of python's duck-typing. If it has an __add__ method, duck-typing says you should be able to provide a starting place and a sequence of things to add to it, and get the sum. However, a new sum2() function can be created... def sum2(seq, start=0): ... for item in seq: ... start += item ... return start ... which does what one would expect the definition of sum() should be doing behind the scenes. # generate the expected error, same as above sum2([q1,q2]) Traceback (most recent call last): File stdin, line 1, in ? File stdin, line 3, in sum2 TypeError: unsupported operand type(s) for +=: 'int' and 'Q' # employ the same solution of a proper starting point sum2([q1,q2], Q()) Q(8,13,16,22) # do the same thing for strings sum2([hello, world], ) 'helloworld' and sum2() works just like sum(), only it happily takes strings without prejudice. From help(sum): Returns the sum of a sequence of numbers (NOT strings) plus the value of parameter 'start'. When the sequence is empty, returns start. It would be as strange as if enumerate() didn't take strings, and instead forced you to use some other method for enumerating strings: for i,c in enumerate(hello): print i,c Traceback (most recent call last): File stdin, line 1, in ? TypeError: enumerate() can't enumerate strings [use hello.enumerator() instead] Why the arbitrary breaking of duck-typing for strings in sum()? Why make them second-class citizens?

Then use single names for interpolation

All-in-all, Ruby is mostly as good as Python in most ways and better than Python in a couple key ways. The big difference between Ruby and Python is the lifecycle phase that the languages/systems are in: Ruby arguably has room for a lot of basic improvements in the architecture of the virtual machine and presumably has a list of must add features that cover gaping holes with respect to certain audiences [1], whereas Python has been around for ages and has covered most of the critical gaps in the feature list (although we can always suggest things which bother our own part of the community). Whereas the Ruby people merely have to agree on how critical their missing features are and to move in one widely agreed direction, the Python people face a tougher choice as to what should be done next; strategies include a tidying-up exercise to make the language more coherent, a complete reimplementation, deep modifications to the runtime, the introduction of radical new semantics. All true, but there's a more fundamental difference that's going to show more as a larger number of people become used to Ruby's semantics: any Ruby statement can be used as an expression. This is firmly from the Lisp family of languages whereas Python's statement-based syntax is firmly in the Fortran branch. With the exception of Lisp itself, no language has seen the popularity of this style of programming until Ruby. I think this represents a real danger to Python's mindshare. Once people have tried expression-based languages, they tend to be loathe to return to statement-based languages. To date, expression-based languages have been mostly of interest in academia or to a small group of elitists and so weren't practical to use for day-to-day work. Ruby has changed that and I think we're just starting to see the fallout. Rails may have brought them there, but Ruby itself is keeping them there. My fear is that the expression-based family of languages is the Homo Sapiens to our statement-based Neanderthals and we can either evolve or disappear. Python is unique in many ways and I'd hate to see those unique features lost because we're stuck on the wrong evolutionary branch. The fewer obvious issues that a language has, the less energy there is in the community to deal with those issues thoroughly, I think. I guess the Perl community chose a bold new direction in line with the observation that a big vision can inspire much more in people than lots of incremental changes to an existing vision, but the energy required to follow through on such a vision can be immense. In addition to all this, a large existing community is more likely to want larger benefits for smaller levels of disruption because of the amount of existing code. Thus, the available energy for change is less in a mature project than in a growing project because people have to constantly monitor the breakage in their existing investments in the language. ...but you can't READ Ruby code. Yeah, that's one of the big reasons I haven't seriously considered trying it. It's expressive, got interesting features... and appears unreadable to me. I'm usually pretty good at deciphering most languages, even if I haven't used them before, but Ruby is one of the exceptions. My feeling is that I'd rather learn more about Lisp or Scheme than Ruby - the benefits are greater and for me Lisp and Scheme increasingly have the edge on readability. Perhaps I'm just not tuned in to Smalltalk-style syntaxes. I'm in the same camp. As I mentioned earlier, it's been mostly inertia and the wealth of the Python community that's kept me with Python. That's why I was so excited when I found Logix. Lisp-like features with Python's syntax that generates Python bytecode. Actually Logix is perhaps too far the other direction as it supports Lisp-style macros and the creation of arbitrary syntax, which perhaps would justify some of the fears people have of Lisp-like languages. The part I found appealing was having Python-like syntax in an expression-based language, with the capability to integrate completely with Python libraries. Absolutely the best of both worlds. I've been trying to contact the author of Logix to find out what the status of the project is or if he's abandoned it. If you haven't looked at it you really ought to. http://livelogix.net/logix/ This brings us back around to the web framework debates. For many people Ruby fits their brains and for others Python does. I think frameworks are similar. I tried Django and while I thought it was a great product, it simply didn't fit how I think about that problem
can't destroy a wxMiniFrame
Hi, I have a miniframe composed mainly of combo boxes, that I need to destroy and recreate multiple time with different choice lists for the combo boxes. My problem is that even after destroying a miniframe with the Destroy() method, when it is recreated, the combo boxes show the same lists of its previous incarnation... how can I completely destroy a miniframe?

My problem is that even after destroying a miniframe with the Destroy() method, when it is recreated, the combo boxes show the same lists of its previous incarnation... how can I completely destroy a miniframe? From what you wrote, I think that you did not create a new miniframe. Although you called Destroy(), you tried to display it again. This is what the documentation says about destroy. Destroys the window safely. Use this function instead of the delete operator, since different window classes can be destroyed differently. *Frames and dialogs are not destroyed immediately* when this function is called -- they are added to a list of windows to be deleted on idle time, when all the window's events have been processed. This prevents problems with events being sent to non-existent windows. Regards, Laszlo -- http://mail.python.org/mailman/listinfo/python-list
[ANN]pygccxml 0.8.1
I'm glad to announce the new version of pygccxml is available. Download page: http://www.language-binding.net/pygccxml/download.html What is it? ...The purpose of the GCC-XML extension is to generate an XML description of a C++ program from GCC's internal representation. Since XML is easy to parse, other development tools will be able to work with C++ programs without the burden of a complicated C++ parser... The purpose of pygccxml is to read GCC-XML generated file and provide a simple framework to navigate C++ declarations using Python classes. Project home page: http://www.language-binding.net/pygccxml/pygccxml.html Changes: 1. The project has been ported to Mac OS. 2. New type traits that works with STD containers were added. 3. Logging and user messages related functionality were improved. 4. Support for Java native types was added. 5. Cache classes implementation and performance were improved. You can find the full list of changes here: http://language-binding.net/pygccxml/history/history.html#version-0-8-1 -- Roman Yakovenko C++ Python language binding http://www.language-binding.net/ -- http://mail.python.org/mailman/listinfo/python-list

It's an Editor based on wxPython. NewEdit is the old name, and UliPadis the new name. UliPad uses Mixin and Plugin technique as itsarchitecture. Most of its classes can be extended via mixin and plugincomponents, and finally become an integrity class at
creating the instance. So UliPad is very dynamic. You can write thenew features in new files, and hardly need to modify the existingcode. And if you want to extend the existing classes, you could writemixins and plugins, and this will be bound to the target class that I
call Slot Class. This technique will make the changes centralizedand easily managed.What are its features?*Cross platformo based on wxPython, so it can run anywhere that wxPython
