SqueakMap trouble
by Stéphane Rollandin 07 Dec '05

07 Dec '05

hello, a few days ago, et today again, I tried to register with no success a new package on SqueakMap, called StringFormat. what happened twice is quite strange: I could create the package without trouble, but I could not register a release (a red message saying "something went wrong" is the only feedback I got) at this point the package stayed for a while on SqueakMap (one hour or so ?), and then simply vanished. as long as it was listed on the packages list page, the link to "new objects" did not respond. when the package disappeared from the list and the whole SqueakMap, "new objects" worked again fine, but my object was gone. I am quite puzzled. what is happening ? it looks like some kind of cleaning mechanism has taken the power in SM logic. did someone else experiment this ? Stef

Swiki question
by Blake 07 Dec '05

07 Dec '05

Hey, squeakers: I have a Wiki up that's just been vandalized but drug-peddling 'bots. I know this happens (a lot) but I don't see how to roll back to a certain date/time. Is there a way, or do I have to clean it up item-by-item?

ANNC: ComSwiki 1.5 ("One Of These Days")
by Jochen F. Rick 07 Dec '05

07 Dec '05

Greetings, I am hereby announcing Swiki 1.5 ("One Of These Days"), running under Comanche 7.0.2. You can get pre-packaged downloads from the Swiki Swiki: http://minnow.cc.gatech.edu/swiki/15 This is the first release to include AniAniWeb. I've been meaning to open-source AniAniWeb for some time, but I've been really busy. I'm still really busy, but I thought I'd at least get it out there. Ani is a Wiki approach applied to personal home pages. It differs in several important ways from a Wiki. There is more structure and a bigger emphasis on looks. Most importantly, Ani has user accounts and a fairly sophisticated access control system. Owners of a site can control who has access to what. For some examples of AniAniWeb in action, see http://home.cc.gatech.edu/ For documentation or to ask questions, go to http://home.cc.gatech.edu/AniAniWeb To start using AniAniWeb, in addition to the other instructions, you must set the alertSender and alertServer fields of the refs swiki. You can do this using the AdminTool, by first clicking on refs and then clicking on settings. Please send all bug reports, comments, and random gunfire to swiki-bugs(a)cc.gatech.edu and/or pws(a)cc.gatech.edu Thanks for your consideration, Je77 -- Jochen "Jeff" Rick, PhD Candidate, Georgia Tech College of Computing jochen.rick(a)cc.gatech.edu, http://www.je77.com/, work: 404-385-1105

Update: mailing list trouble
by Cees De Groot 06 Dec '05

06 Dec '05

Ok, we found out yesterday what was wrong with the list: our IP, together with a whole range from Hetzner, is listed on SORBS as a dialup/dynamic IP address. Mail servers that rely on SORBS will therefore not accept mail. Hetzner has opened a ticket with them last Monday, we have opened a ticket with them yesterday, but no response yet. Therefore, I conclude that mail adminstrators would be well adviced not to rely on SORBS for blocking email - they suck. If you are hurt by this (hope you can read this through the mailing list archive ;-)), complain to your mail admin, not to us. Or simply circumvent the problem by reading the list through Gmane... Regards, Cees

Re: [Q] Why Squeak don't have a Singleton class ?
by Chris Muller 06 Dec '05

06 Dec '05

Sounds like you want to do what MaSingleton does, declare "current" a class-instance variable instead of a class variable. Then you don't repeat the #current method on all your singletons.. > Message: 5 > Date: Sat, 03 Dec 2005 09:56:27 -0500 > From: rvclayton(a)acm.org (R.
