Last night's PySIG meeting
Seven folks graced the Amoskeag Business Incubator for an exciting and interactive night looking at dabo, the three-tier rich-client python framework for database application development. We watched the videos of Ed Leafe's presentation at the recent PyCon conference in Texas and compared experiences in getting dabo up and running, our first challenge. The videos were compelling; there are some tremendous features in the package, and we resolved to have a followup meeting once we've had a little more success diving into the package and can actually talk about how to use it.

In Linux, no one can hear you Wine
Ok...sorry for the cheezy tag line. I turn to you all in desperate hope that someone can offer some aid in a few issues I'm having with Wine. I have talked to a few people and been doing a LOT of Google time and reading but it seems for so many people Wine just works now days. Once again, I'm exceptional. :-) Here's the story. I basically am just trying to get some older Windoze games running. I've been keeping my W98 / Celeron 333MHz box chugging along in pain for WAY too long just so I have some place to feed my addiction. I first tried Wine under Debian, then agian in early 2005 when I switched to SuSE 9.3 and yet again now that I moved to SuSE 10. In the Debian and SuSE 9.3 incarnations I tired installing Wine from source, but when I went to 10 people told me to trust SuSE and just just install Wine out of YaST. I made very little progress way back on the Debian install, but both of the SuSE attempts ( from source and from YaST have had the same results ). Everything seems to just work EXCEPT sound. I have so far tried two different games ( Master of Orion II and Pharaoh ) with the same results. I'm able to run the installation of the DOS game, and in the case of Pharaoh where it has music playing during installation that sounds fine. As soon as I try running either game though, they appear to play fine but absolutely no sound effects or music comes thru. The opening movies and cut sceens are as silent as in-game activity. I'm having a few other minor annoyances ( display resizing probs and a couple programs complaining about versions ) but those are all secondary to just getting some sound here. Any help would be greatlly appreciated. -Lawrence ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

Suggestion - for older DOS based games, try dosbox instead of Wine. (http://dosbox.sf.net) I've had much better luck with that, and there's less overhead. Of course, that doesn't help much with Windows games. -- Cole Tuininga [EMAIL PROTECTED] ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
Re: Fedora ftp install without a name server?

HTTP would mean a single TCP connection on the world's favorite port, so that might be a good idea. I'm comming back to my original theme. FC5 install can't access the files using http, but konqueror on knoppix has no trouble. It's hard to believe that Fedora team didn't test the net install at all, so perhaps it has something to do with not finding the machine via a name server. The mildly informative logging screen (vitrual terminal 3) that I can find shows it looking for: http://192.168.0.2//d1/repodata/repomd.xml and earlier, in the ftp wars: ftp://192.168.0.2//pub/d1/repodata/repomd.xml I'm suspicious of the double slash after the IP address. I've been specifying d1 (http) or put/d1 (ftp) in the location on server box. I'm not specifying a leading slash, but when it loops back after the error message, the installer has added one. In the ftp series, I had tried using non-anonymous ftp so that vsftpd would accept full paths so long as the user used haw permission for those directories and /var/ftp/pub/d1 in case the double slash was causing ftp to try to go from the root filesystem, but no joy. (Again, all of these access methods work from knoppix using the command line ftp client in active or passive modes, and using konqurer.) Can anyone with name server experience suggest a toy nameserver configuration file just to serve up 192.168.0.2 in response to some simple name? (I could RTFM, but I really don't have a general need to know how to set up name servers. If only there were a bach VT running at this point, I could probably type in an etc/hosts and resolve.conf on the RAM fs that the installer is probably running on, but alas...)

PVR-350/ivtv
So I finally got around to getting my PVR-350 card working under Ubuntu. It was rather painless. But I'm used to the old WinTV cards and using xawtv. Since this uses ivtv xawtv doesn't work. I can use the perl/tk program to control the channel, and VLC to watch it, but there is a delay do to the encoding/decoding of the stream. Since I don't need to change the channel much becuase of my setup at home (I have a modulator that runs the whole house, TiVo on channel 60, normal receiver on channel 70). But when I use the remote for my TiVo with the IR repeater, there is a noticable lag that I don't get from a normal TV, or when I used to use my old WinTV card. Anybody else experience this? know of any fixes? ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

Re: In Linux, no one can hear you Wine
What version of wine are you running? If it's the one that shipped with SuSE 9.3, or even SuSE 10.0, it's wa out of date. Best bet may be to visit the winehq website, look for the latest release and check carefully for pre-compiled binaries. Often/usually, one of the SuSE staffers makes an unofficial but usable RPM for the later SuSE distros that installs quickly and easily.That said, once you get wine installed, you need to read up on it and take careful note of what it can and cannot do currently. I finally had to dig up a copy of W2K and throw it on a spare disk in order to install the software for my Garmin IQue3600 PDA because the installation system used by Garmin/Palm simply wouldn't work under wine - kept barfing on the .msi files or somesuch. So, there are still a lot of unfortunate gotcha's. I had similar problems with a commercial program used to program handheld radio transcievers used in the land-mobile and amateur markets - it could install on W! indows 3.1, but NOT under wine.HTH,BayardBrake for moose - it can save your life (NHFGD) New Yahoo!

database modeling tools (again)
Hey Everyone, Based on previous suggestions I've been using Database Designer 4 from fabForce. It works alright but has some annoyances. The worst annoyance is an issue when entering new columns into a table. It's kind of hard to describe, but basically it forces you to stay on the field even when you try to click off of it, or won't let you focus on another column. Anyone that's used it probably know what I'm talking about. The other big problem I have is that rather than drawing key constraint lines between the elements in the tables involved, it simply draws lines between the tables. That gets somewhat confusing on large databases because you can't immediately see what elements are linked to what. Does anyone know of any other free modeling tools that might address these issues? I could live without the lines going from element to element, as it seems most programs don't have this support (although i can't understand why). I suppose I could do it the old-fashioned way, but now that I've got a taste for automatic script exporting I'm not sure if I can look back! thanks, -chris ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

And at one time it was possible to down an interface, but not have it be deleted. That was essentially the difference between what 'ifconfig' and 'ifconfig -a' told you. The -a gave you *all* the interfaces which were configured, regardless of up or down state. Simply using 'ifconfig' only told you about those which were up. That's why I was using the 'del' syntax, which I discovered by looking at code someone else had written 4 or 5 years ago to manage virtual interfaces in a very consistent/predictable way based on the local environment and how we use such things. Things may have changed since that code was written. I note that *my* man page also says this: del addr/prefixlen Remove an IPv6 address from an interface. My ifconfig at home comes from the net-tools 1.60-4 version (Debian). This came up at work, I don't know which/whose ifconfig we're using there, I didn't think to look at the time. -- Seeya, Paul ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

Ya, a bug in net-tools, but you are using an invalid syntax. Buggy
software and sudo definately dont mix :(
Calling 'del' with an IPv4 IP on an interface that doesn't exist
causes the call to for_all_interfaces() from set_ifstate() to not find
the interface. It doesn't handle this case and assumes you want to
add the address as a secondary address on the base interface.
Two bugs here:
1) del with IPv4 actually adds if what you specify doesn't exist.
2) add and del assume you only call it with a parent interface name
'eth0' not 'eth0:anything here' adding a second ':nnn' anyway.
The following actually work:
ifconfig eth0 add 10.107.33.189
ifconfig eth0 del 10.107.33.189
but run 'del' a second time and it adds it back, but with the correct
name (bug)

SIOCSIFADDR on 'eth0:0:1' will create the interface. Kernel is doing
what it's told although with a very non-standard interface name. As
long as it starts with 'eth0:' it considers it an alias.
