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

DHCP

Some weeks ago I have done a hard-disk-installation -- if I enter all network parameters manually, then network will work. Any suggestions how to debug AOS DHCP? Reading full DHCP specs and connecting an Linux-computer running a network monitor like Etherreal should work, but maybe there is a simpler way?

Garbage
by Soren Renner 23 Jul '05

If one is running a very recent crazy-fresh bluebottle, and one is leaking memory, so that every time one runs one's experimental realtime raytracer it leaves the heap with less free space, what should one do? Hypothetically?

Re (3): [Oberon] Multiple VNC clients connecting to Bluebottle?

Thomas, tf> ... only works if you are running Oberon in the window manager. OK. I have Oberon running over the WM on a machine with 32 MB RAM. Nifty! tf> [Aos.Call AosVNC.Open ip:p ~] should open a window asking for the input of the password. It works! All this happening in 32 MB! > It should open a window asking for the input of the password. Setting passwords with NetSystem.SetUser entries in Oberon.Text was efficient. Having to submit a password on demand seems regressive. After exiting the terminal session and closing the VNC viewer, a new session won't establish. Aos.Call AosVNC.Open 137.bb.cc.dd:5901 ~ gets a viewer but no terminal session. Rebooting the Debian TightVNCserver allows a new session. Something must remain locked after the first session closes. No such problem with an Aos VNCserver? Regards, ... Peter Desktops.OpenDoc http://carnot.pathology.ubc.ca/

Sven, > ... mount ... in the Autostart section of AosConfig.XML. That works. Thanks. The mount also works as Boot9 in Aos.Par. For the present I am using ETH Oberon / Aos 08.06.05 as a full screen interface. In this case Autostart.Run is not necessary. Even the main menu of the WM is not needed. Mounting the USB with Boot9 is sufficient. After this system is stable for a week on two, I'll update information on the Web in case anyone is interested. > No, the OHCI host controller initialization will always complete before > the USB driver is started (AosUsb.Init), but the later will work > concurrently to the boot process. Sorry, I was confused. > ... force the USB driver initialization to wait until bus > enumeration is finished.

This problem appears to be independent of the preceding. >>On the other hand I could observe that sometimes while copying many >>files - about 100 MB - the copying stopped without any message.

Josef, Sven, > ... two fixes in AosUsbOhci and AosUsbStorage from 19th of July ... Just compiled your two fixes of July 19 again, to be sure they were not missed. Configured Aos.Par again to try to mount the USB with Boot2. Still the USB memory is not mounted. Sven mentioned that completion of the Ohci Init before the attempted mount is a question of chance. Since I have different, probably older and slower, hardware from you, failure of the mount here seems possible. A simple solution is to mount the USB in AOS:Oberon.Text; it works. Naive question for the day: Is there no way to suppress concurrency during boot up? Seems concurrency causes more trouble than it is worth at the early stage. Regards, ...

Mounting USB memory on USBOhci. (Was "compiler".)
by shark＠gulfnet.sd64.bc.ca 21 Jul '05

21 Jul '05

Yesterday evening (2005-07-19), being only semi-conscious, I said, pe> The Ohci driver seems OK but Partitions.Show still ignores the USB memory. Well I can mount the USB manually after the system is viable. A few lines from the Kernel.Log. AosOhci: Initialised USB Open Host Controller at base 0E5000000H, Irq: 10 AosUsb: Driver UsbHub (integrated USB hub driver) has been added. AosUsb: USB driver loaded. AosUsb: Driver UsbStorage (Usb Storage Device Driver) has been added. AosDiskVolumes: USB0 not found AosDiskVolumes.New failed AosUsb: Kingston DataTraveler II+ attached to USBHC0 port 2. Appears that PCIFindOhci is not finished when Boot2="AosFSTools.Mount USB AosFS USB0#02 ~" is attempted. So how can Aos.Par be arranged so that Mount is attempted after PCIFindOhci is finished? (By way of interest, there was no such problem with Uhci. With Uhci the memory was USBSCSII rather than USB.) Thanks everyone, this is interesting, ... Peter E.

USB Open Host Controller Driver, AosUsbOhci.Mod.
by shark＠gulfnet.sd64.bc.ca 19 Jul '05

19 Jul '05

Recently I installed a new Belkin F5U220 USB card in a Pentium system lacking on-board USB. The Belkin card supports OHCI and EHCI 1.0. In Aos.Par I replaced AosUsbUhci.Init with AosUsbOhci.Init. The Kernel.Log has this entry AosUsbOhci: IO space not mapped. and USB does not work. My comprehension of PCI and OHCI is minimal. Hints or instructions will help. Thanks, Peter E.

N-o image formats ?
by easlab＠absamail.co.za 17 Jul '05

17 Jul '05

Recently some one mentioned a n-o package/utility, and I viewed the sample output, which I believe was a pc-board. The view image was very economical compared to gif or jpg but quite sufficient for the task. Perhaps I had to use the 'convert to Pict-format' facility to view it. Can someone tell me the utility name & URL and the image format ? BTW which clown put this 'disaster' on our to get list http://www.cs.ucr.edu/~phf/mir/<spamTrap>wirth-compiler-1996.pdf ? I aborted after 6.2MB download. At 2K char per A4 text-page, that's a fat book, when plain test is used. Thanks, == Chris Glur.
