Re: [Pharo-project] What are you using to write reports?

No argument that MS wants to kill COM in favor of .NET, and once they do that, they will churn the market again as soon as they can manage it - it's what they do. They've been sufficiently ineffective at it that the result is hardly "writing software over and over" but it is very annoying to watch working things break over time. These annoyances combined with the general merit of Linux distributions of late led me to make the switch. In short, you are preaching to the choir :) Let's be honest a third time :) Word is trash. Open Office Calc is really pretty good. Since you (wisely) distrust Microsoft, I find it strange that you are content to throw around the "Office is standard" mantra. True or not, there are alternatives (in the case of LaTeX, a paradigm shift from fussing with formatting to thinking about structure) and ways to have data in simple formats that will still be around long after Microsoft starts to kill off .NET's successor. You can set yourself up for more pain, or design for the minimum amount of Microsoft involvement that will solve your problems. There are some good options in this thread, or you can polish up your .NET compiler, while it still has time ;) Good luck!

I'm usin VBA currently, the problem with it is that MS want to get away from it. And so I should probably long for something with .NET in it's name. But well if MS wants to get rid of it, one day we may stay in the rains as e.g the VB6 people have been treated. Sure currently MS is all just .NET (in whatever) shadow. But nobody knows how long, and let's be honest who likes to write the same software over and over and over again just because the development tools and/or languages were deprecated. And let's be honest a second time. MS-Office is the Standard by any means. Yes there is LaTex and yes there is OpenOffice but sorry if anyone talks about Office Software they mean MS-Office. And we have to admit that the MS-Office tools are extremly useful, especially Excel is quite good at that spreadsheets can do ;-) > > OpenOffice has some type of (Java??) scripting interface.

Well VBA and Excel is well working, I doubt that OpenOffice Basic can compete with it.

Hi Friedrick, In Aida and specially Scribo CMS we now support the commercial Prince PDF generator (http://www.princexml.com) Prince converts HTML + CSS3 into nicelly formated printable documents, with page numbers, Table of contents with page numbers and such things, necessary for professionally looking documents, while reatining the original documents in strictly standard HTML/CSS format. Prince is developed with help of one of authors of CSS standard, so you can expect the true support as advertised. For less "professional" printing Aida supports the print CSS separation from screen CSS, so you can do quite good printouts with pure HTML/CSS, as much as web browsers printing support allows. That printing support is not very complete, but my company anyway print all our documents that way, from bills, letters etc, so it is good enough for most cases. If a customer really need better one, then you "scale" to Prince.

Each object has to know its class. Now...image those classes where you have a lot of instances, like Bitmap, ByteString, etc...(print Smalltalk compactClassesArray for more examples) If for each instance of them you need 32bits (4 bytes) to point to their class, you will use "a lot" of memory. So, someone introduced something in the VM where they modified the Object Header so that you can use 5 bits for an index in a table of compact classes. So you have 32 classes that you can define as compact (see #becomeCompact), and this means that its instances will have an object header small (without a real pointer to its class). Thus....saves memory. However, the system has to ask if it is compact or not several places in the vm, having an overhead I imagine. IMHO, they could be removed since it is not THAT MUCH in today's computers. And the VM would be cleaner. cheers mariano > > Rgs, James. > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >

[Pharo-project] float printing

by stephane ducasse

hi guys here is a point where squeak and pharo could sync. Now I propose the change to be applied in Pharo. http://code.google.com/p/pharo/issues/detail?id=2888 in essence 0.1+0.2=0.3 which is normal since (0.1+0.2) hex '3FD3333333333334' 0.3 hex '3FD3333333333333' showing that we are in presence of two difference numbers. So since floats are approximations anyway, I like the idea that the language tells me all the time. This fits perfectly with the discussion and actions we got last year on floats. Of course 0.1s2 + 0.2s2 = 0.3s2 is true storeString is already conveying the right information both in squeak and pharo (0.1+0.2) storeString '0.30000000000000004' 0.3 storeString '0.3' I suggest that printString on float ie on little change in printString. So talk now. My point is that since we cannot perfectly lie better say it. I think that GNU and python are right so this an easy fix with a really good impact on education. Stef printOn: aStream base: base "Handle sign, zero, and NaNs; all other values passed to absPrintOn:base:" self isNaN ifTrue: [aStream nextPutAll: 'NaN'. ^ self]. "check for NaN before sign" self > 0.0 ifTrue: [self absPrintExactlyOn: aStream base: base] ifFalse: [self sign = -1 ifTrue: [aStream nextPutAll: '-']. self = 0.0 ifTrue: [aStream nextPutAll: '0.0'. ^ self] ifFalse: [self negated absPrintOn: aStream base: base]]

we are interested in a Smalltalk based image writer too :) So far we did not went far and just focus on playing with SystemDictionary Hi All, > > I'm looking for information on the image file format, something that tells me the layout. > A little like this: > > +--------+ > ! version ! > +--------+ > ! count ! > +--------+ > > etc. I can glean this information from the Squeak C sources but I'm wanting some > additional information for validation.

Compact classes are classes whose representation is optimized and normally you can have up to 5 bits (32) compact classes in the system. I reminder that eliot mentioned that he would like to kill compact classes. Would be good to have a system less complex.

In scriptLoader you get the list of all the core packages with version.
