[ANN] Release 0.42 of Task Coach
Hi all, Hi all, I'm pleased to announce release 0.42 of Task Coach. New in this release: Bugs fixed: * Double clicking a task with children in the tree view would open the edit dialog and expand or collapse the task as well. Fixed to not collapse or expand the task when double clicking it. * Adding a subtask to a collapsed parent task now automatically expands the parent task. * Changing the description of a task or effort record wouldn't mark the task file as changed. * Time spent is now updated every second. * Don't try to make a backup when loading the file fails. Reported by Scott Schroeder. * (Windows installer only) Association between .tsk files and Task Coach was broken. Feature changed: * The start date of a task can now be left unset, creating a task that is permanently inactive. This can be useful for activities that you would normally not want to plan, but have to keep a time record for, e.g. sickness. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://taskcoach.niessink.com https://sourceforge.net/projects/taskcoach/ A binary installer is available for Windows XP, in addition to the source distribution. Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release.

Roundup Issue Tracker release 0.8.4
Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry Track design competition. This 0.8.4 release fixes some bugs: Fixed: - extra CRs in CSV export files on Windows platform (sf bug 1195742) - activity RDBMS columns were being reported in changes - fix name collision in roundup.cgi script (sf bug 1203795) - fix handling of invalid interval input - search locale files relative ro roundup installation path (sf bug 1219689) - use translation for boolean property rendering (sf bug 1225152) - enabled disabling of REMOTE_USER for when it's not a valid username (sf bug 1190187) - fix invocation of hasPermission from templating code (sf bug 1224172) - have 'roundup-admin security' display property restrictions (sf bug 1222135) - fixed templating menu() sort_on handling (sf bug 1221936) - allow specification of pagesize, sorting and filtering in classhelp popups (sf bug 1211800) - handle dropped properies in rdbms/metakit journal export (sf bug 1203569) - handle missing Subject lines better (sf bug 1198729) - sort/group by missing values correctly (sf bugs 1198623, 1176897) - discard, don't bounce messages to the mailgw when the messages's sender is invalid (ie. when we try to bounce, we get a 550 unknown user account response from the SMTP server) (sf bug 1190906) - removed debugging code from cgi/actions.py - refactored hyperdb.rawToHyperdb, allowing a number of improvements (thanks Ralf Schlatterbeck) - don't try to set a timeout for IMAPS (thanks Paul Jimenez) - present Reject exception messages to web users (sf bug 1237685) If you're upgrading from an older version of Roundup you *must* follow the Software Upgrade guidelines given in the maintenance documentation. Roundup requires python 2.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: python demo.py Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/projects/roundup Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup = Roundup manages a number of issues (with flexible properties such as description, priority, and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable out of the box with any python 2.3+ installation. It doesn't even need to be installed to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and five database back-ends (anydbm, sqlite, metakit, mysql and postgresql). -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
Sydney Python Meetup July 21: Python, Perl, and Cold Beverages
Date: Thursday July 21 Time: 6:00pm-8:30pm, with drinks and food during and after. Topics: Graham Dumpleton on The Vampire mod_python extension Paul Fenwick So you want to start a business? Place: James Squires Brewhouse 2 The Promenade, King St Wharf Sydney Fee:$0.00 The Sydney Python meetup group is on this Thursday. The meeting time has been brought forward half an hour, and the formal part of the evening will commence promptly at 6:30pm. The James Squires Brewhouse managed to book the Python Meetup Group and the Perl Mongers in adjoining rooms for the same night. Everybody has promised to be nice and we'll be combining with them to hear from one of their Melbourne gurus. As always, everybody is welcome. Graham Dumpleton, author of Vampire, will be speaking first (6:30-7:30). He describes his presentation thusly: Although I'll talk a bit about the motivations behind writing Vampire and why this extra layer on top of mod_python is useful, what I want to talk about more is what I have learnt from writing Vampire. From that I would like to go on to describe a new and better way of doing this same thing for mod_python that Vampire attempted to do. This new approach moves even further away from the monolithic framework approach towards small building blocks of functionality that can be slotted together to build up a web application how you want it and not how some framework dictates you should do it. More information on Vampire can be found at http://www.dscpl.com.au/projects/vampire/ Paul Fenwick of the Melbourne Perl Mongers will also be speaking (7:30-8:30). His talk, So you want to start a business, will be presented at the SAGE-AU conference later this year, and an abstract can be found online at http://www.sage-au.org.au/conf/sage-au2005/speakers.html#fenwickabs -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html

More general: let be M a set of expressions and X a subset of M where each element of X commutes with each element of M: how can a product with factors in M be evaluated/simplified under the condition of additional information X? It would be interesting to examine some sorting algorithms on factor lists with constrained item transpositions. Any suggestions? Hello Kay, take this into account: Restrictions like commutativity, associative, distributive and flexibility laws don't belong neither to operands nor to operators themselves. Instead these are properties of fields (set of numbers with respect to a certain operation). For a famous example for a somewhat alternative behaviour look at the Octonions (discovered in 1843 by Graves and 1845 by Cayley), which are not associative with respect to addition and/or multiplication. (http://en.wikipedia.org/wiki/Octonions) or the Quarternions, which are non-commutative (http://en.wikipedia.org/wiki/Quaternion) Obviously, it's not correct to say: addition is associative, or, that multiplication is. With the same right, you could say, multiplication is not associative. With the same reasoning, we can show that it's not easy to generalize sorting, commutation, association or distribution mechanisms. Maybe it would be a very fascinating goal to solve your algorithmic approach in such a limited environment like the Quarternions. A solution for this set of numbers, if achieved in a clean, mathematically abstract way, should hold for most other numbers/fields too, natural and real included. I guess that the approach might be this way: - define/describe the fields which shall be handled - define/describe the rules which shall be supported - find methods to reduce sequences of operations to simple binary or unary operations (tokens) - this may introduce brackets and stacking mechanisms - a weighing algorithm might be necessary to distinguish between plain numbers and place holders (variables) - application of the distributivity (as far as possible) might help to find a rather flat representation and a base for reordering according to the weights of the individual sub-expressions Nevertheless, there are lots of commercial programs which do such sort of symbolic mathematics, and which would badly fail when it would come to such awkward fields like Quarternions/Octonions.

How do you use CreatePrintDialog from win32ui? About a year ago someone posted that: dlg = win32ui.CreatePrintDialog(1538) dlg.DoModal() will give you the window, but the ok button does not work. Here is what I did to make it work: code import win32ui from pywin.mfc import window, dialog class WindowsPrintDialog(window.Wnd): # Numbers for various items in the dialog PROPERTIES_BTN = 1025 PRINTER_NAME= 1139 PRINT_TO_FILE = 1040 PRINT_ALL = 1056 PRINT_PAGES = 1058 PRINT_SELECTION = 1057 FIRST_PAGE = 1152 LAST_PAGE = 1153 FROM_TEXT = 1089 TO_TEXT = 1090 NB_COPIES = 1154 def __init__(self): dlg = = win32ui.CreatePrintDialog(1538) window.Wnd.__init__(self, printDlg) def OnInitDialog(self): ## Initialize dialog itself self._obj_.OnInitDialog() ## Activate all widgets for i in (WindowsPrintDialog.PRINT_ALL, WindowsPrintDialog.PRINT_PAGES, WindowsPrintDialog.FIRST_PAGE, WindowsPrintDialog.LAST_PAGE, WindowsPrintDialog.FROM_TEXT, WindowsPrintDialog.TO_TEXT, WindowsPrintDialog.PRINT_SELECTION): itm = self._obj_.GetDlgItem(i) itm.EnableWindow() ## Disable Properties button: it doesn't work... itm = self._obj_.GetDlgItem(WindowsPrintDialog.PROPERTIES_BTN) itm.EnableWindow(0) def OnOK(self): ## Call on dialog itself self._obj_.OnOK() self._obj_.UpdateData(1) ## Now you can get values entered in dialog via: ## - self.IsDlgButtonChecked(id) pour check-buttons ## - self.GetDlgItemText(id) for textual fields ## - self.GetDlgItemInt(id) for integer fields ## Then use these info. to create your printer DC; for example: printerName = self.GetDlgItemText(WindowsPrintDialog.PRINTER_NAME) dc = win32ui.CreateDC() dc.CreatePrinterDC(printerName) ## And so on... /code Note that the printer properties button is explicitely disabled. If it's not, it seems to be working (it actually opens the printer properties dialog and all options can be modified without any error), but actually doesn't change a thing: the printing will be done with the printer default settings. If anybody has any idea on how this thing works, please let me know: I'm very interested. Diging into the source shows that the 1538 is being loaded as a template resource. The MSDN documentation does not say anything about this being neccessary and in fact, other common dialogs provide this as an option, but not a requirement. Why is this made a requirement? If it was not made a requirement, would the dialog work? I guess it would just be a matter of giving the default value 1538 to the idRes parameter in win32ui.CreatePrintDialog; AFAICT, this is always the id for the default print dialog. Can't figure out why it was not done in the first place... Unfortunately I can't play with this because I don't have Visual Studio. I guess the logical next step, if the above worked, would be to add the GetPrinterDC() method (and maybe some others) so that we can do something useful with the dialog. Yep. See above.

Java RMI-like services in Python
Hi, I am wondering if Python has services or frameworks that does the same as Java RMI? What I am seeking is to do pseudo-clustering. That is, a server will contains a program to control what is needed for execution. This will be pretty much like process management. Call this controller, HeadControl.py. What HeadControl.py can do is to expose a SOAP interface. Each client machine will have Executor.py. So when Executor.py is executed, it will connect to HeadControl through SOAP. HeadControl will then spawn a thread to represent the connection. Now, this part is possible in Java, but I am not sure if it is possible in Python. Executor will find out from HeadControl what it can do and downloads the corresponding objects and data from HeadControl and executes it and sends results back to HeadControl. 2 scenarios that this might work. Firstly, Executor can be part of a client program. In this case, temporary files may be written to the client's HDD. Of course, due to security, this method may not be desirable. Secondly, Executor may be made into a web applet kinda thing. In this case, writing to HDD may be impossible. I know something like this had been achieved in Java (http://www-128.ibm.com/developerworks/java/library/j-super.html) but wondering if it is possible in Python. Is so, how? Thanks.

[Ron Adam] Currently we can implicitly unpack a tuple or list by using an assignment. How is that any different than passing arguments to a function? Does it use a different mechanism?

Re: Ordering Products
I have to admit that I don't understand what you mean with the 'constant parts' of an expression? From what I percieved of your example it seemed to me that you wanted to evaluate the constants like 7*9 first, so that an expression like a * 7 * 9 * b with variables a,b is evaluated like this: a * 63 * b So my suggestion was simply to make the *-operator more precedent when in between two constants. What I mean with constants here are of course integer/float literals. The concept of a differing operator precedence can be extended to arbitray elements when their types are known - which should be possible when variable values are known at parsing time. The associativity of __mul__ is trivially fullfilled for the dummy class M if an additional __eq__ method is defined by comparing factor lists because those lists are always flat: I don't care about that, as my approach deosn't use python's built-in parser - it can't, as that wouldn't allow to re-define operator precedence. What you do is to simply collect the factors as list. But what you need (IMHO) is a parsing tree (AST) that reflects your desired behaviour by introducing a different precedence thus that the expression a * 7 *9 * b is not evaluated like ((a*7)*9)*b (which is a tree, and the standard way of evaluationg due to built-in parsers precedence rules) but as a*(7*9)*b which is also a tree. The sorting ( or better 'grouping' which can be represented by sorting in a special way ) of factors in question is really a matter of (non-)commutativity. For more advanced expressions also group properties are important: No, IMHO associativity is the important thing here - if (a * 7) * 9 yields a different solution than a *(7*9) your reordering can't be done - in the same way as re-arranging factors a*b to b*a only works if the commute - or, to put in in algebraic terms, the group is abelian. If a,b are in a center of a group G ( i.e. they commute with any element of G ) and G supplies an __add__ ( besides a __mul__ and is therefore a ring ) also a+b is in the center of G and (a+b)*c = c*(a+b) holds for any c in G. It would be nice ( and much more efficient ) not to force expansion of the product assuming distributivity of __add__ and __mul__ and factorization after the transposition of the single factors but recognizing immediately that a+b is in the center of G because the center is a subgroup of G. Well, you don't need to expand that product - the subexpression a+b is evaluated first. If you can sort of cache that evaluation's result because the expressions involved are of a constant nature, you can do so. The rason (a+b) is evaluated first (at least in the standard python parser, and in my proposed special parser) is that the parentheses ensure that. To sum things up a little: I propose not using the python built-in parser which results in you having to overload operators and lose control of precedence, but by introducing your own parser, that can do the trick of re-arranging the operators based on not only the usual precedence (* binds stronger than +), but by a type-based parser that can even change precedence of the same operator between different argument types is's applied to. That might sound complicated, but I think the grammar I gave in my last post shows the concept pretty well. regards, Diez -- http://mail.python.org/mailman/listinfo/python-list

Something I was thinking of is a sort where instead of giving a function, you give it a sort key list. Then you can possibly sort anything in any arbitrary order depending on the key list. sort(alist, [0,1,2,3,4,5,6,7,8,9]) # Sort numbers forward sort(alist, [9,8,7,6,5,4,3,2,1,0]) # Reverse sort sort(alist, [1,3,5,7,9,0,2,4,6,8]) # Odd-Even sort sort(alist, [int,str,float]) # sort types Seems like you want to establish a total order of elements statically. Don't believe that this is necessary. I want to establish the sort order at the beginning of the sort process instead of using many external compares during the sort process. Using a preprocessed sort key seems like the best way to do that. How it's generated doesn't really matter. And of course a set of standard defaults could be built in. These are just suggestions, I haven't worked out the details. It could probably be done currently with pythons built in sort by writing a custom compare function that takes a key list. Exactly. The advantage of doing it as above would be the sort could be done entirely in C and not need to call a python compare function on each item. It would be interesting to see if and how much faster it would be. I'm just not sure how to do it yet as it's a little more complicated than using integer values. How fine grained the key list is is also something that would need to be worked out. Could it handle words and whole numbers instead of letters and digits? How does one specify which? What about complex objects? In order to handle complex objects one needs more algebra ;) Since the class M only provides one operation I made the problem as simple as possible ( complex expressions do not exist in M because __mul__ is associative - this is already a reduction rule ). Kay I'm played around with your example a little bit and think I see how it should work... (partly guessing) You did some last minute editing so M and Expr were intermixed. It looks to me that what you need to do is have the expressions stored as nested lists and those can be self sorting. That can be done when init is called I think, and after any operation. You should be able to add addition without too much trouble too. a*b - factors [a],[b] - [a,b] You got this part. c+d - sums [c],[d] - [c,d]Need a sums type for this. Then... a*b+c*d - sums of factors - [[a,b],[c,d]] This would be sorted from inner to outer. (a+b)*(b+c) - factors of sums - [[a,b],[c,d]] Maybe you can sub class list to create the different types? Each list needs to be associated to an operation. The sort from inner to outer still works. Even though the lists represent different operations. You can sort division and minus if you turn them into sums and factors first. 1-2 - sums [1,-2] 3/4 - factors [3,1/4] ? hmmm... I don't like that. Or that might be... 3/4 - factor [3], divisor [4] - [3,[4]] So you need a divisor type as a subtype of factor. (I think) You can then combine the divisors within factors and sort from inner to outer. (a/b)*(c/e) - [a,[b],c,[e]] - [a,c,[b,e]] Displaying these might take a little more work. The above could get represented as... (a*c)/(b*e) Which I think is what you want it to do.

Dictionary, keys and alias
I want to insert a concept of alias in a dict_based class.
The idea is to have a facoltative name in the same dict that correspond
at the same value. With this alias i can change original value.
example:
mydict['a'] = 1
I must define an alias example: myFunctAlias( mydict, 'a', 'b')
print mydict
{'a':1, 'b':1}
mydict['b'] = 2
print mydict
{'a':2, 'b':2}
The only idea i have is to implement two dictionary one for convert
name, alias in two keys with the same value (eg.numeric) in the first
dict. The second for store only one time the k, v .
Any suggestion ?

I favor speed of development, intensive OO development, performance under heavy load, short learning curve, good documentation and community. I settled on CherryPy: Performance under load -- can't say one way or the other. I do know it's lightweight -- 40kb download, I recall. Good documentation -- yeah, if you are using the mainstream features. It's pretty extensible, too, so there are some secondary functions and features that are not as well documented. I know that the documentation is a major concern of the oommunity, and that they are pretty quick to respond when the docs are unclear. I give CherryPy very high marks for: speed of development, intensive OO development, short learning curve (if you already know Python), and community. And, as I said, for extensibility. I found I had working apps running on my machine with CherryPy in less time than I needed to read the installation docs on some other frameworks. It's just like writing Python, but with one extra object (cpg (2.0) or cherrypy (2.1) and one extra setting (exposed = True). That's it.

The idea is to have a facoltative name in the same dict that correspond
at the same value. With this alias i can change original value.
example:
mydict['a'] = 1
I must define an alias example: myFunctAlias( mydict, 'a', 'b')
print mydict
{'a':1, 'b':1}
mydict['b'] = 2
print mydict
{'a':2, 'b':2}
The only idea i have is to implement two dictionary one for convert
name, alias in two keys with the same value (eg.numeric) in the first
dict. The second for store only one time the k, v .
You need some sort of redirection, something like this (untested):
class Doubledict:
def __init__(self, **kargs):
self.data = {}
self.aliases = {}
for key in kargs:
# Point the key to a hash.
self.aliases[key] = hash(key)
# And point the hash at the value.
self.data[hash(key)] = kargs[key]
def setalias(self, key, alias):
# Point the alias to the same hash as the real key.
self.aliases[alias] = hash(key)
def __getitem__(self, key):
return self.data[self.aliases[key]]
def __setitem__(self, key, value):
self.data[self.aliases[key]] = value
The only niggly worry I have is I'm not sure when hash can be used, when
it is unique, or even if is it guaranteed to be unique.

Re: goto
In python there is no goto statement. In C I use goto only in one case: to exit more then one level of blocks (as a matter of fact, I always use goto EXIT in C, where EXIT is the label of the end of the function). In python you can mimic this by throwing an exception and catching it. Exception should know the destination label name and the catch statement should compare this name with its (catch statement) name.

Bernhard Holzmayer schrieb: Kay Schluehr wrote: Now lets drop the assumption that a and b commute. More general: let be M a set of expressions and X a subset of M where each element of X commutes with each element of M: how can a product with factors in M be evaluated/simplified under the condition of additional information X? It would be interesting to examine some sorting algorithms on factor lists with constrained item transpositions. Any suggestions? Hello Kay, take this into account: Restrictions like commutativity, associative, distributive and flexibility laws don't belong neither to operands nor to operators themselves. Instead these are properties of fields (set of numbers with respect to a certain operation). For a famous example for a somewhat alternative behaviour look at the Octonions (discovered in 1843 by Graves and 1845 by Cayley), which are not associative with respect to addition and/or multiplication. (http://en.wikipedia.org/wiki/Octonions) or the Quarternions, which are non-commutative (http://en.wikipedia.org/wiki/Quaternion) Obviously, it's not correct to say: addition is associative, or, that multiplication is. With the same right, you could say, multiplication is not associative. It was associative in the tiny example I presented. I did not mentioned to discuss the evolving structure of the whole CAS here in detail which would be better done in an own newsgroup once an early version is released. Maybe the setting of the original question should be made more precise: associative, non-commutative multiplicative groups. Handling non-associative algebras like Lie algebras is a completely different matter and I'm not even sure which one is the best way to represent operations in Python? Maye this way? lie = Lie() # create an arbitrary Lie algebra (lie is again a class ) A,B = lie(),lie() # create two arbitrary elements of the Lie algebra lie[A,B] # create the commutator of the lie algebra by overloading lie[A,B] # the __getitem__ method lie[A,B] == -lie[-A,B] True If one wants to enforce assertions like lie[r*A,B] == r*lie[A,B] True for certain elements r of some group acting on lie, one must refine creation of lie in the initial assignment statement e.g. lie = Lie(V) where V is some vectorspace and the elements of lie are homomorphisms on V. V is created elsewhere. There are a lot of constraints induced by all the objects dynamically coupled together. With the same reasoning, we can show that it's not easy to generalize sorting, commutation, association or distribution mechanisms. Maybe it would be a very fascinating goal to solve your algorithmic approach in such a limited environment like the Quarternions. No CAS can represent infinitely many different representations of quaternions. But it should not be to hard to deal with an algebra that represents admissable operations on quaternions in an abstract fashion. A solution for this set of numbers, if achieved in a clean, mathematically abstract way, should hold for most other numbers/fields too, natural and real included. I guess that the approach might be this way: - define/describe the fields which shall be handled - define/describe the rules which shall be supported - find methods to reduce sequences of operations to simple binary or unary operations (tokens) - this may introduce brackets and stacking mechanisms - a weighing algorithm might be necessary to distinguish between plain numbers and place holders (variables) - application of the distributivity (as far as possible) might help to find a rather flat representation and a base for reordering according to the weights of the individual sub-expressions Nevertheless, there are lots of commercial programs which do such sort of symbolic mathematics, and which would badly fail when it would come to such awkward fields like Quarternions/Octonions. If you take a look on Mathematica or Maple both programs seem to interpret pure symbols as members of an associative and commutative algebra: expand( (a+x)^2) - a^2 + 2ax + x^2 This works very fast and accurate but is mathematically too restricted for me. For doing more advanced stuff one needs to do a lot of programming in either language shipped with the CAS for creating new packages. But then I ask myself: why not doing the programming labor in Python and redesign and optimize the core modules of the CAS if necessary? Kay -- http://mail.python.org/mailman/listinfo/python-list

If it's not, it seems to be working (it actually opens the printer properties dialog and all options can be modified without any error), but actually doesn't change a thing: the printing will be done with the printer default settings. If anybody has any idea on how this thing works, please let me know: I'm very interested. In the MFC documentation, CPrintDialog has a GetPrinterDC method. This method AFAICT gives you a printer device contex which has all the settings set for you. Diging into the source shows that the 1538 is being loaded as a template resource. The MSDN documentation does not say anything about this being neccessary and in fact, other common dialogs provide this as an option, but not a requirement. Why is this made a requirement? If it was not made a requirement, would the dialog work? I guess it would just be a matter of giving the default value 1538 to the idRes parameter in win32ui.CreatePrintDialog; AFAICT, this is always the id for the default print dialog. Can't figure out why it was not done in the first place... The problem is that 1538 is loaded as a template resource. I get exactly the same result from many resources all the way up to 2 (I tried them in a loop). I suspect that this number just works because it is an ever present resource id, and does not actually do anything to help us. When used in conjuntion with the rest of the MFC printing framework, the dialog seems to work, but this does not help me because the rest of my application is in PyGTK, I would rather limit my MFC programming to the bare minimum. If I could get the PrintDlg function to work, I would use that instead. Unfortunately I can't figure out how to make that work either. I may just have to pull out MinGW and compile a module that uses the PrintDlg function. Unfortunately I can't play with this because I don't have Visual Studio. I guess the logical next step, if the above worked, would be to add the GetPrinterDC() method (and maybe some others) so that we can do something useful with the dialog. Yep. See above.

Re: Ordering Products
I see, you're sensitive for the difficulties which might arise. That's the thing I wanted to point out. Maybe I was looking too far forward... My first thought was to add attributes/qualifiers to the operands to improve the sorting. Then I realized that these attributes/qualifiers were related to the operators, since multiplication and division use the same operands, but while in one case it is associative and commutative, it isn't in the other. I agree that all this leads too far. But one thing creeps into my mind again: I guess you'll always need an inverse operation: A class which can handle multiplication will certainly require an inverse operation like division.

#self.aliases = {}
def setAlias(self, key, alias):

d.setAlias(a, b)
print d[a], d[b], d[c]
d[a] = 2

d[b] = 3
d.setAlias(b, c)

Result:
1 1 4
2 2 4
3 3 3
3 3 5

As you can see the last test (del a and reassign a) fail because it reassign b.
But, if your application doesn't need to midify the aliases, it's ok (I think). Else you can redefine the method __delitem__.

Windows command line problem
I'm sure someone else has posted a similar problem but I can't find it, nor the solution... I have a python script which accepts a command line argument. E.g. python.exe myscript.py -n Foo I build this as part of a package using distutils with the bdist_wininst option on a Windows 2K (SP4) machine. I have tested installing and running it fine on a Windows XP (SP2) machine. I build my package-installer with a Python.org 2.4.1 distribution which is source-compiled locally. I have installed my package-installer on a machine running ActiveState Python 2.4.1 installed from a .msi file. That all works fine. I have problems delivering it to the test team (of course). After some investigation, if I install the package on one of our test machines and butcher my installed file to dump the command line and exit (i.e. print 'hi', sys.argv) then I get the following: hi ['c:\\Python24\\Lib\\site-packages\\MyPackage\\myscript.py', '\x96n, 'Foo'] If I run it specifying --name instead of -n I get: hi ['c:\\Python24\\Lib\\site-packages\\MyPackage\\myscript.py', '\x96-name, 'Foo'] The machine in question is also running XP service pack 2 as far as I know, with Python.org's 2.4.1 distribution. Does anyone know why the first character on the command line (here '-') is getting adjusted (to '\x96') in this way ? Is it a Unicode/encodings kind of a problem ?

And here is a Python equivalent using exception handling:

Re: Image orientation and color information with PIL?
i = Image.open(blue.jpg) i.size (3008, 2000) i.mode 'RGB' 'RGB' is the value for color jpeg images. I believe that for blackwhite images, i.mode is 'L' (luminosity). If you want to determine whether an existing image is landscape or portrait, then just compare i.size[0] (width) and i.size[1] (height). If by determine if an image is horizontal/vertical, you want to find the orientation data recorded by some digital cameras, you can do that with PIL 1.1.4. According to the release notes for 1.1.4, + Added experimental EXIF support for JPEG files. To extract EXIF information from a JPEG file, open the file as usual, and call the _getexif method. If successful, this method returns a dictionary mapping EXIF TIFF tags to values. If the file does not contain EXIF data, the _getexif method returns None. The ExifTags module contains a dictionary mapping tags to tag names. This interface will most likely change in future versions. The exif tag 274 is Orientation. The values you'll see most often are 1 (Normal), 6 and 8 (90 and 270 degree rotations). Orientation can also encode 180 degree rotation, as well as any of the four rotations combined with a mirror operation. [k for (k,v) in ExifTags.TAGS.items() if v == 'Orientation'] [274] e = i._getexif() if e: print e[274] 1 I have written a standalone Python module that reads and changes the EXIF orientation data.

if you mean that you want to figure out which way the image is depending on the actual data in the image, then you'll most likely get to do the image processing yourself, on the other hand, if you are talking jpegs from a relatively new camera then I suppose that you should be able to get that info by looking at the EXIF information. AFAIK you can read exif with PIL, but not write. -- http://mail.python.org/mailman/listinfo/python-list

Re: Opinions on KYLIX 3 (Delphi 4 Linux)
Hi Doug Not only was Kylix a letdown, there is talk also of it being discontinued. To be fair though, it is easy to see the difficulty for Borland to deploy a Linux IDE of the same quality as Delphi when so much in different Linux distributions is variable, the widget set being a prime example: CLX just never caught on, amongst the myriad of more mature and more open toolsets. I am assuming that you have experience with pascal, or ObjectPascal as the Delphi manuals call it (if not, why Kylix?). If so, may I suggest you look into a) fpc (Free Pascal Compiler, http://www.freepascal.org) b) Lazarus (An fpc IDE, aims to be an open-source Delphi clone, supports multiple widget sets [Win32 native on Windows!], can't remember the URL) Though python is probably my favourite language for general purpose hacking, there is a lot to be said for a native compiled language (sometimes speed _is_ an issue), and in particular there is a lot to be said for fpc: - Something like 99% Turbo Pascal compliant - Very nearly Delphi compliant (object-pascal) - (IMHO) Much cleaner language than C, still natively compiled - Supports operator overloading inlining - Can be used to develop python extensions - Supports nearly effortless cross-compiling There are some problems with Lazarus at the moment, here is the biggie: It creates binaries of around 5MB for a minimal app, and this is because, at the moment it seems like it compiles the component library into the executable. This is somewhat of a problem for me but I expect this will change within a release or two. Lazarus is _very_ much like Delphi, and works on Windows, Linux, and possibly several other platforms. cya Caleb and net for info about Borlands KYLIX 3 and have found little technical info about it. Their screen shots are very impressive, similar to Visual Basic. I have sent several emails to Borlands Sales and Pre-Sales departments. Pre-Sales bounces and Sales won't answer. I'm sitting here with money in hand ready to buy but not from a company that won't give me the time of day. Does anyone of you have experiance with KYLIX 3 and do you think I should consider buying it? Thank You, I'll go oil my keyboard now. Doug -- http://mail.python.org/mailman/listinfo/python-list

My understanding is that it is a horse-racing phrase. Some unprincipled racers would dye a horse to disguise him and get better odds. Obviously this only works to make a horse darker. A dark horse is an unknown quantity -- the phrase is usually only applied to horses that show well without the normal track record preceding that success. --Scott David Daniels [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
