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

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

ODBC help!
by John Stout 25 Feb '04

25 Feb '04

Some time ago I emailed my corrections to the old System 3 ODBC to someone in this mailing list. Due to a catastrophe (don't ask!) I have lost everything on my hard disk. Could whoever it was please email them back to me? John Stout --- Outgoing mail is certified Virus Free.

Has the Oberon mailing list been compromised?
by danforth＠greenwoodfarm.com 23 Feb '04

23 Feb '04

Oberon users, I have now received two suspicious email messages from two members of the (ETHZ) Oberon mailing list. I believe those messages were bogus and not sent by the claimed "from" address. The messages contained an attachement (which I did not open) of the form 'mails.zip' and had a very short sentence in the body of the message such as 'what does this mean?' Hence I assume someone, group, or worm, has stollen the ETH Oberon mailing list. -Douglas G. Danforth

Bluebottle Server Access Problems
by Thomas Frey 20 Feb '04

20 Feb '04

Hi, finally we have been able to track the access problems to our server. Depending on the client operating system's TCP stack and other constraints (timing/scheduling) data can be present in the 3rd TCP packet that establishes the connection. This data was mistakenly truncated by its header length (the offset was increased twice). We expect the problem to be resolved. Please inform us if you experience further access problems to http://www.bluebottle.ethz.ch The fixed crazy release is available at http://bluebottle.ethz.ch/dlcrazy.html --Thomas

n-o: find files containing string-set ?
by easlab＠absamail.co.za 16 Feb '04

16 Feb '04

Hi, perhaps some one can supply the source code for this useful algorithm which I really am getting to need: For EachOfFileSet For EachOfStringSet IF NextString NOT in File then EXIT this file ListFile {which contains each of the strings in any order} Perhaps one can adapt: RX.Grep ( filename | "*" ) [option] RegExpr if "*" could handle <SpecialPartitonForThis>:* Except that my tests show I don't understand how to represent: " string1" AND "string2". And then one would need 2 runs to handle the order for 2 strings, and 6 runs for 3 strings ? BTW string searching must be one of THE greatest demands for heavy usage general IT. The multiple partitions which allow different 'concept' spaces is a great help. Additionally I find that for big partitons, speed-up by skipping *.Bak files is easily acheived, by [instead of using Find.Panel], have on hand <partnID>:SearchList . Where <partnID>:SearchList is made by: 1. System.Directory <partnID>:* 2. System.Store the directory 3. RX.Grep Directory \i ".Bak" 4. re-name as <partnID>:SearchList and store I have a set of: Configuration.DoText Mount<partitionName> in my main Tool. Each one typically has the following 6 lines:----- !OFSTools.Mount Legal AosFS IDE1#28 ~ <-- rotate Bakup 8 June 2003 OFSTools.Mount Legal AosFS IDE0#28 ~ ! System.Directory Legal:* ! OFSTools.Unmount Legal ! SmartDir.Directory Legal:*\r 3 <-- very useful; edit "3" to step back in time ! Legal:SearchList ---------------- And the <partnID>:SearchList is typically a few hundred files wrapped thus:--- Updated 2004 Jan 18 Find.All ^ Find.Domain Legal:Absurd Legal:ActionDateX Legal:AdminJustc .... Legal:derebus.org.za ~ ---------------- The n-o documentation which advises having 2 or 3 partitions, show a lack of appreciation of the increased power of having many separate "concept spaces". But now one really needs to be able to find files containing multiple strings. Related to this need, I think that if google died tomorrow, the world would shake ! Thanks for any help. Chris Glur.

The TCP bugs seem to be resolved. The crazy release can be downloaded again from http://bluebottle.ethz.ch/dlcrazy.html If no new showstoppers appear, the new release can be expected in about two weeks. --Thomas

N-O: editor's 'global' search-string incompatible
by easlab＠absamail.co.za 08 Feb '04

08 Feb '04

How many n-o users are we ? That this may seem a trivial refinement, is because n-o is already so matured and well tuned. A search-string may/should be conveniently searched for in different text-frames by just repeatedly activating the 'Search' of the various frames. Apparently the 'last search string' is retained in a global; a convenient default, like the 'last deleted string'. That this global [last search string] differs eg. between the Edit.Open and Desktops.OpenDoc frame-families is unfortunate. Not so much because the user looses the efficiency of not having to re-set the 'search string' when going to an incompatible (from the previous frame) frame; but that he is likely to forget that his assumed 'search string' is invalid. Serious errors can be caused, because there cannot be an error warning. Ie. he may base important decision on the false belief that <search-string> is NOT in text-frame X. A similar/opposite problem which is confusing for the beginner is that the find-utilities insist that "Oberon10.Scn.Fnt" is in the file. This appropriately invisible string, being part of the header-formatting-info is less likely to perpetuate false decisions than the original mentioned quirk (eg. mistakely insisting that: "your email does NOT contain the <string> - possibly in the High Court !). When/if you go the fetch <search-string> (eg. "Oberon10.Scn.Fnt") you will soon find, it's not there, but won't make false claims about a string being absent. -------------------- Is it a problem in future versions to have the same global search-string in all editor types ? BTW there are good reasons why a user would want/need to use both (incompatible in this minor respect) frame families; eg. Desktops.OpenDoc doesn't do ' TextMail.Cite * ' With the rapid cut-n-paste facilities, it's quiet practical to move a text-strech to a diiferent editor/frame-type, just to use a certain facility. A bit like unix, rather than hoping for the editor which does everything. Modularity & evolutionary refinement is best. == Chris Glur.

The project must be seen as a heirarchy/tree. And the higher goal(s) must be known before their components are discussed. I guess WebDAV's final goal is to allow collaboration on different versions of different projects ? If so you perhaps have [and note the tree structure]: persons ID, password project version files read write execute - perhaps apparently from what I read the files have 'attributes' which are important. In a top-down view, one knows why the attributes are important, before one knows how to get the attributes.
