Active Oberon on ARM CPUs
by Stauber Sven Philipp 17 Apr '07

17 Apr '07

Dear all, In about two weeks, I'm going to work again on a project which uses the ARM version of AOS. At that time, I will provide an image that runs on XScale PXA25x/PXA26x CPUs (maybe also others, I'm not sure) and the corresponding sources for those who are interested. I'm going to announce the availability of these files on this list. Regards, Sven Stauber

AosTar.Mod
by Yaroslav Romanchenko 16 Apr '07

16 Apr '07

Dear BB developers, Why Tar archives produced by AosTar.Create are incompatible with Unix Tar archives? Information that provided in headers is insufficient for a lot of software. Provided only name, size and checksum, but size and checksum values are with leading "0", when they must be with leading "Space" chars. --- Cheers, SAGE http://sage.com.ua/

Hi All, I'm glad to inform you that I want to contribute my application to Bluebottle OS. This is an chat application consists from server and client parts, that if it will be started on bluebottle.ethz.ch server, realtime fast online chat conversation for all of us will be achieved. Only registering (obtaining of unique User ID code) is needed. So, Enjoy! For compiling of application recent crazy-fresh release of BB is needed! And of course we need started server! Application's web page: http://sage.com.ua/en.shtml?e1l4 Application is available under direct link: http://sage.com.ua/files/Sage.UDPChat.zip -- Cheers, SAGE http://sage.com.ua/

I read that Wirth's ARM-based helicoper project, which I thought was just a hobby thing, won 2nd prize, [against MIT] with substantial 'other than software engineering' input from ETHZ. IMO remote flying vehicles are the new cutting-edge military technology. H-bombs are no good against terrorists. IMO the time for low-power/portable computers and hence also Oberon has arrived. It seems that ARM leads the way. Although Analog Devices' Blackfin Uprocessor looks interesting too ? Some years back Wojtek Skulski who used to contribute to this forum was promoting an oberon compiler [by someone else from ETH] for an Analog Devices Uprocessor. Recently I stumbled on a group [but I've lost the URLs now] who are making an oberon compiler for the Blackfin. And the pAste below traces my recent attempt to get info re. low-power CPU's which would run oberon:-- >> I assume you have knowledge of Analog Devices blackfin processors, > > which apparently have a clinux port. > > > > I'm interested in a minimum powered linux system, and Analog Devices > > http://www.analog.com/processors says: > > " ADSP-21xx Processors, are code- and pin-compatible families of Digital > > Signal Processors with performance up to 160MHz and power as low as > > 184 micro-amps.

Re. portable CPUs, OLPC seems not to be reaching it's target, since there's talk about it being manufactured in Nigeria, where they can't even refine their own petroleum. Here too in S. Africa: "give us local production contracts, where we can have extra opportunities for skimming for ourselves and our cronies, and we will give you the goverment contract", is old hat. == Chris Glur.

Darwin Oberon 2.4.3
by Roger Vossler 07 Apr '07

07 Apr '07

Hi, Does anyone know if Darwin Oberon has been ported to Mac OSX 10.4.x on Intel Macintosh hardware? If not, does anyone know if a version of Darwin Oberon that worked on a Macintosh G4 or G5 processor will work with Rosetta on an Intel Macintosh? Thanks for any information, Roger.....

Since 1/2 hour it is up and well! It is not Oberon2.4.3. It's the alpha of the Unix hosted Aos which can now be used on Linux/x86, Solaris/x86 and Darwin/x86. It is far from completion but the Native Oberon part is fully functional. In short: Aos core modules + Oberon + concurrency + paco compiler. -- Guenter -- Oberon(a)lists.inf.ethz.ch mailing list for ETH Oberon and related systems https://lists.inf.ethz.ch/mailman/listinfo/oberon ____________________________________________________________________________________ Looking for earth-friendly autos?

New release of April 3, 07
by Ulrike Glavitsch 04 Apr '07

04 Apr '07

Dear BB users, a new crazy-fresh release is available under http://www.bluebottle.ethz.ch/dlcrazy.html for download. It contains a number of new features contributed by Sven Stauber (Performance Monitor, System Event Logging), Florian Negele (Diff Tool) and the students Ingmar Nebel (Diff Tool), Reto Meier (Mail Client) and Mathias Ottiger (USB HID Driver). Thanks to them all! Performance Monitor 2.0 The performance monitor is now able to display monitored values using grids and can therefore handle much more such values. A lot of plugins have been added, in particular almost any AOS kernel / network related statistics variables can now be monitored. There's a new section in AosConfig.XML where you can specify which plugins should be loaded at application start. Since it's somewhat impractical to monitor such a large number of values by looking at it, Performance Monitor Alerts have been introduced. Using alerts you can specifiy a trigger condition that causes an user-specified action when triggered, for example, if a certain monitored value becomes greater than a user-specified constant, notify the user. System Event Logging A system event logging framework has been introduced to reduce the amount of information displayed in the event log that is used by many applications. In comparision to outputs using AosOut, events provide the following advantages: - event classification enables efficient filtering - events are time-stamped when entered into the event queue - events can be logged to kernel log, files or memory Mail Client The release now contains a mail client for IMAP/SMTP. The application provides powerful search facilities for both online and offline mail browsing. The mail client does, however, not (yet) support authentification. USB HID Driver Up to now, the Bluebottle HID drivers only supported HID boot protocols. These are simplified protocols that are supported by HID mice and keyboards to enabled simple implementations of BIOS mouse/keyboard support. The new HID driver is a real adaptive device driver that makes use of the HID report descriptors that are provided by all HID devices. For practice, this means: - mouse: no hack required for mouse wheel support, up to 32 buttons supported - keyboard: support for special keys - joystick: support for 8 axis, 32 buttons and 1 coolie hat Diff Tool A tool that visualizes the differences of two files has been contributed. Both a command line front-end (DiffLib.Mod) and a graphical user interface (WMDiff.Mod) are available. I wish everyone good luck with the new release.

Question concerning Arrays
by Eric 04 Apr '07

Hi all, In Java one can assign an array value to an array variable like so: int[] A = {0,1,2} Can one write something similar in Oberon? E.
