I looked at MinneStore a couple of months ago, and got Jon Carlson, who wrote it, to send me test suites etc. Unfortunately, I haven't had time to do anything about it, and it doesn't look as though I will :-(. However, it seems a fairly straight forward port... Minnestore is under the GNU licence, so it's free, but not as unrestricted as the Squeak licence. If anyone wants to port Minnestore to Squeak, email Jon at jonathan_carlson(a)technologist.com, and I'm sure he'll send you any stuff you need. > This kind of persistent object facility is the biggest gap (for my purposes) > in the vast functionality provided by Squeak -- or at least it seems > that way from my newbie perspective. I totally agree - it's one of those basic abilities Squeak should have. Squeak is one of the most impressive pieces of software I have seen. Keep up the good work!

Lex, There seems to be a problem. Trying to download Scamper, I get ----- Forbidden You don't have permission to access /~lex/squeak/www0.3/ on this server. ----- In the area of VM improvements, I mentioned earlier the possiblity of giving Scamper a greater share of the processor without the UI losing control altogether. I have just finished some VM changes that remove a stumbling block in this area (on the Mac, at least) and was just about to test with the old Scamper when I saw this. I will check back later to see if the permision issue is sorted out. Cheers, Bob

[snip] Thanks for the suggestion. I think that nearly all programs that are used and maintained over time need revision control either formal or ad hoc, not just those maintained by more than one person. Obviously I do not include those written in APL. It is of course a write-only language. And again, these products, and other free versions, add very useful features that are difficult to implement. It seems to me the model of the SDE makes it much more difficult than need be. A (poor?) analogy might be programming in C using one monolithic "code edit" file for all projects, then partitioning out pieces into various .c and .h files to package them in some kind C "program". I do not have nice things to say about the way C compilers assume source is stored, but it does seem in some ways easier to manage. I just think it might be worth stepping back for a moment to consider whether there isn't a better SDE approach than the source and changes files. A future project -- I think it's 3,691th on my list -- is to directly store the SDE code in RCS with the method being the smallest check in/out unit. Using a declarative model of Smalltalk initialization code, pool, class and method definitions would all be stored there. Damn I'd really like to see some that declarative model Smalltalk code so I'd know what it looks like. I may have made a dumb suggestion -- I'm better at quantity than quality -- but it still seem like a good idea to me. -- Richard A.

update of my Web browser
by Lex Spoon 14 Aug '98

14 Aug '98

Hello, It's been a couple of weeks, so I'm posting a new version of my web browser. There are several new things added since the last version: - a simple page-history fascility - a personal start page - inline GIFs - two new form inputs: option lists and radio checkboxes - mailto: link to Bob Arning's mailer, if present (untested) - MIDI files are played automatically (working on generalizing this) - file: URLs for Unix users (working on generalizing this) - HTTP redirects - a functional frames implementation, a la Lynx The things that I'm immediately thinking of working on in the next week or two are: - figuring out what kind of VM support could make things faster - playing with thread to make things smoother on big operations - finishing up the rest of the form inputs - some sort of initial table support (if anyone has different priorities, speak up :)) There's a page on the Swiki at: http://minnow.cc.gatech.edu/squeak.14 with links to the code.

As long as we're on the subject... >There is a compressed archive of both interpreters, the image, and changes >files. There doesn't seem to be a standalone binary of the Jitter. I'd try building one, but I don't have CodeWarrior (too expensive) or MPW (huge download). I've seen mention of a web browser plug-in that either is a Squeak interpreter or passes code to the interpreter. That sounds very exciting and I'd love to see it work.

Siren on Win 95 MIDI?
by Shaun M. Smith 13 Aug '98

13 Aug '98

Hi Squeakers, I've been trying to determine whether STP's Siren works on the MIDI support that's available in the 2.1 Win95 VM. Perhaps someone a little more in the know could summarize the status. I think I remember a posting from STP that mentioned future Win95 support for Siren, but I may be wrong. I believe the main roadblock is the MIDI driver interface. Are the Mac and Win95 VMs currently using the same MIDI drivers. The Siren readme says that the Opcode MIDI System (OMS) drivers are required. A summary of MIDI on Win95 would be appreciated. Not all of us have Macs, even if we'd like one :-). Thanks very much, Shaun Shaun M.

(Well, maybe not, but I'll do it second thing: I have a driving test at 07h45 [which really counts for "six impossible things" all at once, so maybe Squeak will have to wait until _after_ breakfast]. ;) Just watch the regular place...

[snip] I have been increasingly uneasy about the way Smalltalk handles its code sources -- especially code change management, revision control (RC), and maintaining backup of the code. Although I've never used Smalltalk professionally, I think I do serious programming in it. In my limited experience, RC seems a tacked on after-thought, rather than a integral part of the software development environment (SDE) that any meaningful development will need. I seems Smalltalkers have come up with creative and useful solutions to manhandling the SDE into handling change, but I wonder why it requires manhandling in the first place. I've begun to think the Smalltalk (SDE) model might ought to be changed from storing code in source and change files to store all versions of code in a database. I have no experience with databases, but what little I've heard leads me to think this might solve a lot problems with RC. Databases are available off-the-self, a tested technology, run on most every platform, have facilities for maintaining their integrity. They have backup and recovery, checkpoints for rolling changes in and out, a lot of utility tools, and could handle the large number of method and other sources for fine-grained control. In my experience with public domain Revision Control System (RCS) and other source control packages, keeping the current source version, and the deltas to previous versions, allows on quick retrieval and generally only takes twice the space required for one full text source. A less radical approach I think would help a great deal is to use RCS instead of the source and change files If the DB idea is too silly, please give me enough warning to duck the rotten fruit and vegetables. -- Richard A.

Versionitis
by invader＠zilker.net 13 Aug '98

I have Squeak 2.0 for Mac and Squeak 2.1 for Win32. Do I dare just run the 2.1 image with my 2.0 VM? I would just try it, but it is pretty big and one is at home and the other is at work. I did fileOut some of the stuff from the 2.1 image and it ran great? Now, the big question is how do I find out other than by diffing the sources or someother horrible operation. Is there a Swiki around that has this info? Who decides what goes in a version or when a version comes out? Oh, well. I guess I could go on, but I'll stop there for a while. Curious minds want to know. mkd
