Re: [Oberon] Export of Oberon Mail.SendCmd().

Generally, re-using code instead of copying is a good approach. If you do so, then the whole code of Mail is imported in News. Possible but perhaps there is even a better approach to re-use code. What about this: try to separate all common code in an own module (e.g call it Communication.Mod or MsgBase.Mod or Utilities.Mod or so) and import this new module in Mail and in News. br Jörg > Am 14.06.2023 um 19:53 schrieb peter(a)easthope.ca: > > Hello again, > > Several procedures in Mail are used in Oberon News.

Version numbering in the A2 repository.

Hi, https://git-scm.com/docs/user-manual#exploring-git-history has this example. $ git bisect start $ git bisect good v2.6.18 A local copy of the A2 repository is here. To imitate the example, a version number is needed. Where can version numbers be found? Thanks, ... P.L. -- VoIP: +1 604 670 0140 work: https://en.wikibooks.org/wiki/User:PeterEasthope

If the green is too much, happy to remove it. I'd rather cite Wirth's sources in a more permanent and tamper proof location. At present, don't know of any. Feedback welcome, thanks, ...

Paul, Thanks for replying.

For reference by others, will leave for a few days before reverting. Additional replies welcome. Besides adding a note that the styling is Wirth's and to please not change, edit protection may be possible. Can investigate. A third way to preserve Wirth's orginals is to put in Wikisource. It's expressed in HTML (it's on the Web) but but presented as the original (resistant to tampering as PDF is). https://en.wikisource.org To me, Wikisource would honor Wirth's work but won't consider it without approval of Wirth's family and academic authorities. I acknowledge that original publications remain available from bookstores and libraries and the wikibook isn't necessary. My argument is about accessibility. Most of the population of the world doesn't have convenient access to an academic library and out-of-print books can be expensive. Always open to debate. Thanks & BR! ...

Hi, A recent edit of Oberon/V2/Input in the wikibook replaced my style tag with tag 'syntaxhighlight lang="oberon2"'. Links to the two versions are at the top of the history page. https://en.wikibooks.org/w/index.php?title=Oberon/V2/Input&action=history If the two versions are marked, a click on "Compare selected revisions" will show the changes side by side. You'll see that the edit was made from an address rather than from an authenticated account. My original styling was crafted to imitate the appearance in Wirth's book. Black text in the Times New Roman font. syntaxhighlight uses a Helvetica (?) font with keywords colored green. I appreciate the eagerness of an itinerant editor to help but sometimes "help" misses an intention. My instinct is to keep Wirth's styling. (A note about that at the top of the page may be justified.) What do experts say? Leave syntaxhightlight? Revert to Wirth's styling. Thanks, ... P.

Announcement: Oberon for the Raspberry Pi Pico and Pi Pico 2
by Chris Burrows 08 Nov '24

08 Nov '24

We recently released Astrobe for RP2040 which can be used to write Oberon software to run on the Raspberry Pi Pico microcontroller boards. This will be followed up later this month by the release of Astrobe for RP2350 which targets the new Raspberry Pi Pico 2 boards. For more details see the Astrobe forum announcement: https://www.astrobe.com/forum/viewtopic.php?f=3&t=799 The RP2040 is based on an Arm Cortex-M0+ processor whereas the RP2350 uses the more powerful Arm Cortex-M33 design. During testing we came up with the following performance comparison: https://www.astrobe.com/forum/viewtopic.php?f=19&t=803 The test program that we ran was originally written in Modula-2 by Wirth for his Lilith computer. It is documented in Appendix 2 of the *ETH Report Nr 40 - The Personal Computer Lilith* (The Yellow Report). Apr 1981. N. Wirth which you can download from: https://www.astrobe.com/Modula2/ The results shown there indicate (taken with a huge grain of salt) that the Pi Pico is ~ 50x faster, and the Pi Pico 2 is ~ 100x faster than a Lilith. The price comparison of the systems is even more impressive at ~ 5000x: The Lilith cost ~ $US 8000 (~ $US 25,000 today) whereas you can get a Pi Pico 2 for $US 5 Regards, Chris Burrows -- CFB Software https://www.astrobe.com
