Oberon Database
by Dan Parnete 19 Sep '05

19 Sep '05

Hello, I have read this list archives, the documentation inside the distributions, some extra found on the web and I understood. Database is a Tabu word in this community, and is better to not talk about. There is no trace in any distribution (excluding the commercial BlackBox) and the new Bluebottle project doesn't intend to implement one. Ok. It's a choice of live. But don't tell me none of you never needed to put some data altogether. I can't believe nobody extended at list the Library code to more flexible collections management. I saw some database projects started long time ago. Where are this implementations? In other words: if I need a database, have I write it myself? Dan

Re: [Oberon] Support for Realtek RTL-8139 with Native Oberon

The driver is currently only available for the new Bluebottle OS. http://bluebottle.ethz.ch It should not be too difficult to make a Native Oberon driver out of the Bluebottle OS driver. But... I have no time to do this myself. --Thomas Frey

Mail.Panel topiclist magic
by edgar＠edgarschwarz.de 24 May '04

24 May '04

Hi, I'm extending Mail.Panel to allow it to work with multiple mail files. So I can e.g. drop mails which are sent to an invented address at edgarschwarz.de and other spam my filter catches to a spamfile automatically. Now I would like to be able to select my target mail file using a button and the same mechanism like the topiclist for Set,Clear and Move. I tried to duplicate all and created a repolist model and also the buttons/iconizers panel says it's connected to a RepoListModel but somehow it still shows the topiclist instead of my repolist (mailfile names). So can anybody give me a hint what's going on inside of the Gadget system and whether I can find out somehow which data is accessed when I MM on my button ? Too much magic in there :-( Cheers, Edgar

WinAos on a network
by John Stout 19 May '04

19 May '04

As part of my plan to get Oberon, specifically WinAos, adopted at my college for teaching programming, I would like to set things up so that WinAos works on our network. This is Windows based, mainly XP. On logging on a user gets an N: drive which is mapped to their home directory. Since the network people are creating a new clone image I can arrange for WinAos to be installed locally on all the C: drives, and I can put a new Oberon.Text and Aos.Text in this folder with N:/Work rather than just Work in the directories sections. Has anyone done anything like this? I assume I will need to create a Work directory in each Computing student's home directory with a minimal Aos.Text and Oberon.Text. The desktop shortcut will specify N:\Work as the startup directory. John Stout --- Outgoing mail is certified Virus Free.

Re (2): [Oberon] PSPrinter.Mod
by shark＠gulfnet.sd64.bc.ca 04 May '04

Bernhard, b> To the best of my remembrance ... Ctrl-D should not be harmful if it is not required, ... Do the manuals for the new PostScript printers mention this? There is a LaserJet 4P manual here. In a troubleshooting table, page 8-16, "end-of-job" is mentioned. Seems that all PostScript printers might use 04X to signal end-of-job and the machines at the ETH have AUTO-CONTINUE set on. That way the job is assumed finished after a time-out, and there is no error. A sloppy way. Better to send the 04X properly. When there is time to spare I'll look to see what is involved in putting a parameter in Oberon.Text. Tips are welcome. Thanks, Peter http://carnot.pathology.ubc.ca/

To the best of my remembrance of PosScript and PS-printers a Ctrl-D should not be harmful if it is not required, but I am not shure about it. Ctrl-D signals EOF to the RIP. It would also explain some problems I had with printing to a Brother HL-1670N, but I have to check that at work. regards -- Bernhard Treutwein BdT (at) wildwein de (home) Bernhard Treutwein (at) verwaltung uni-muenchen de (work) > ----- Original Message ----- > From: <shark(a)gulfnet.sd64.bc.ca> > To: <oberon(a)inf.ethz.ch> > Sent: Friday, April 30, 2004 3:37 AM > Subject: [Oberon] PSPrinter.Mod > > > > Oberon readers, > > > > There is a LaserJet III here with an HP PostScript > > cartridge and PSPrinter is installed in ETH Oberon > > / PC Native 05.01.2003.

I'm guessing that "Mail.Panel in Bluebottle" is based on [copied from] Mail.Panel in "Mail.Panel in n-o" ?? Inet working can be quiet problematic because part of the enviroment: the modem, telco-line, ISP [usualy set up for MS clients] is out of your control. Here are some of my experiences with n-o: * n-o standAlone V 2.3.2 would not connect with Mail.Panel . After some investigation I guessed that it could be a marginal timing issue which could be confirmed by different hardware. * n-o DOSbased V 2.3.6 would not connect with Mail.Panel , but TextMail.* was OK. * n-o 2001 connects both Mail.Panel and TextMail.* I don't think the source code was changed [perhaps I should check ?], so I imagine the success or failure is due to critical timing. When my ISP(s) changed, I had 2 problems with login and email [which I have discussed here], and which I hacked-around/patched the source-code. I few days ago NewsGroups were inaccessable under n-o, with what looked like an error message from the server. Linux pine and Win3.1 Forte Agent [another killer-ap] connected OK, so I guessed it being another [like the 2 previous] n-o assumption which didn't comply with the RFC. Now today after 4 days failure, the news-server connects. I'm guessing that other clients complained and the news-server admin. restored the changes which they had made. So one is working partly in the dark. When the SWEN virus hit, my ISP "help desk" insisted that there was NO PROBLEM. I was the only clown in the universe who though there was a problem !! Be prepared for frustration. == Chris Glur.

Chris, cg> filter/modify the data to be as the 'consumer' wants, ... In this case, filter = PSPrinter.Mod and consumer = "LaserJet III with PS cartridge". Hours after submitting the story to the list, the possibility of configuring in Oberon.Text dawned on me. One of these might be workable. PSPrinter = { ... TerminateWithControlD } PSPrinter = { ... TerminateWithControlD = True } This would be a "study" for me. Would be prudent to have the approval an expert before wasting time. Many such small repairs and improvements must have surfaced since the last alpha, 2003-01-05. SSH and PPP for example. I wonder whether a new alpha might be worth considering before the beta or full release is ready? (Not that I know how to build.) Regards, Peter http://carnot.pathology.ubc.ca/
