Alain, Success is the important thing; and you seem to be making strides in the correct direction.

[Pharo-project] serializing object graphs / ordering graph anchors

by Norbert Hartl

Before I start a utility myself I want to ask if there is such a tool already. I'm using sixx for object graph serialization. It works quite good but it has some severe limits. Well, the limits are not really sixx dependent but a problem of usual serializers. My problem is the size of the stack such a tool generates. Especially in gemstone this appears to be a problem because the stack is limited per gem. If I look at the serializers I know the mechanics are simple: 1. take an object and look it up in a table. 2. if the object is in the table it has already been serialized. We take a reference from the table and write it down 3. if it isn't in the table it means the object has not been serialized and the contents need to be written. After that the object with a reference representation is written to the table 4. while writing the content of an object (inst vars) I encounter simple objects (direct string representation) or complex objects (composite). In the latter case we start over from 1. If the object graph is well interconnected than the odds are high that a stack will grow high until the first reference can be written. With a small pier kernel I already matched a stack size of 1000. One solution I can think of is to collect and order objects in the graph that cover smaller segments from the overall graph. This way I would construct a sorted collection that is sorted by stack depth (lowest first). The collection will then be serialized leading to a much smaller possible stack sizes. It might be there are cases it can't work but I think for most cases it will do its job. And it will be slow of course. Does anybody know if such a tool exists? Norbert

Re: [Pharo-project] usability of Pharo and Squeak

by Andreas Wacknitz

After following the discussion for some time, I have the impression that there are some smalltalkers suffering similar usability problems like my friend and me and some more or less enjoy the actual state. Dolphin 6 Professional introduced IdeaSpace. With that you can have both - single windows and tabbed windows. It's up to the user to either open windows outside IdeaSpace as independent windows or inside IdeaSpace as tabbed windows. Having the free choice is a good thing. Especially if you don't want to alienate newcomers that are used to use tabbed windows. I like this approach. I haven't looked at TWM yet due to lack of time. I am hardly able to read the mail traffic in the evenings. But I asked my friend to have a look at it. He promised to do so although it's not suited to Pharo 1.2.1. As Pharo 1.3 is not yet stable I fear that he might have new problems in other areas. What strikes me during this discussion is that nobody seem to have the same problem with window sizes and positions. I don't like RealEstateAgent and I don't think that a revamped one will solve the problems. At least as long it doesn't provide the possibility to set sizes on the fly. No algorithm can guess the requirements of all users. I also haven't heard about applications written in Squeak or Pharo and what about user thereof think about the usability. IMO there is a lack of an appropriate framework for dealing with such things. Or is everybody developing web applications nowadays? I have a hard time to promote Smalltalk because of its actual state. I always tell people about my favorite programming language, but I also tell them that alas there is no good implementation of it available. This is sad but true, even if Pharo and Squeak made big progress during the last months. Both, Squeak and Pharo, aren't products but just tools. And that makes a big difference. The commercial products have characteristics that make them not very attractive to people not yet involved. Despite Dolphin they all have dated user interfaces, too. When I try to convince people to have a look at Dolphin they typically tell me: very nice but it seems to be dead already. Regards, Andreas
