Re: [maemo-developers] User interface stuff on maemo.org
Hello! Glad to hear another Nokian is around to help. Are you involved with planning for a scalable/multi-resolution UI or other cosmetic changes? I know there's been some work towards this and was wondering if there were any mock-ups or conceptual art of what might develop.

[maemo-developers] Waiting for DBUS events in shell scripts
During my experiments with DBUS (see my other message) I tried to react to DBUS signals through shell scripts; However, I encountered a strange problem: I tried to parse the output of "dbus-monitor --system", which should be no problem with sh, grep or awk. But there is an issue regarding the buffering of its output pipe. What I tried to code boiles down to the following lines: dbus-monitor --system | while read LINE; do ; done However, nothing happens. I noticed that no lines are passed through the pipe, which can be checked by this command: dbus-monitor --system | cat - Instead of printing dbus events to console, nothing happens. I guess that this might be a buffering issue with busybox or dbus-monitor, however these commands work fine on the Debian system installed on my notebook. What would be even cooler than this would be a dbus-signal-wait command, which just sleeps until a specified events occurs; This way, a shell script waiting for internet connectivity could just be implemented by writing: while dbus-signal-wait -i com.nokia...; do use_connection done OK, any comments regarding my ideas? :-) -- .:[EMAIL PROTECTED] | [EMAIL PROTECTED] | GPG: finger [EMAIL PROTECTED] °:. |_ http://stefans.datenbruch.de/__ __| | Wer Header fälscht oder verfälscht oder gefälschte oder verfälschte Header | `-__in_Umlauf_bringt_wird_mit_Scorefile_nicht_unter_-500_Punkten_bestraft__-' ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
[maemo-developers] Hooking into network configuration
Hello, I got my Nokia 770 a few days ago, and I am quite impressed and satisfied; However I am confused about the network configuration. I have done some tweaks to both Debian (http://stefans.datenbruch.de/interfaces/) and iPAQ/Familiar (http://stefans.datenbruch.de/h5450/) networking, and was somehow disappointed that Maemo does not use /etc/network/interfaces for network configuration, although the file provides everything needed to store multiple configuration PLUS a lot of flexibility when it comes to more complicated setups. For example, my university uses a Cisco VPN to give us wireless access to the internet; I have to use VPNC to gain a working net access, and I was able to make it work automatically by hooking it into the network setup descriped on my pages above. I would like to do so as well on my Nokia 770, but I did not find any scripts triggered during interface configuration; I also started to investigate DBUS activity (http://stefans.datenbruch.de/nokia770/) during network initialization, but was unable to hook into it using simple shell scripting (more about that in another mail). I also think that this might be too late - After issuing the DBUS message, all apps will think that internet connectivity is available, so in my opionion there should be a script thriggered before this DBIS signal is emitted. I'd even prefer a debian style setup via /etc/network/interfaces, which already has all abilities to handle profiles, callbacks etc. The generation of DBUS signals would be quite easy to implement through apropiate scripts in "/etc/network/if-up.d/" (if-pre-up.d, if-down.d, if-post-down.d etc.) Of course this would require a doog parser for that file. So, is there a way of hooking into the network configuration process, perhaps even delaying the "internet available" signal until my vpn client has established his connection? -- .:[EMAIL PROTECTED] | [EMAIL PROTECTED] | GPG: finger [EMAIL PROTECTED] °:. |_ http://stefans.datenbruch.de/__ __| | Wer Header fälscht oder verfälscht oder gefälschte oder verfälschte Header | `-__in_Umlauf_bringt_wird_mit_Scorefile_nicht_unter_-500_Punkten_bestraft__-' ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

[maemo-developers] Mono : HttpWebRequest in c# my nokia 770 (mono-nokia 1.1.13-1)
Hello,
I try to use HttpWebRequest
in c#/Mono on my nokia 770 (in fact, I want to use Web Services). The first part of the below
program which use TcpClient() works very well: I can get a page from a distant
server.But with the second part,
which use HttpWebRequest, fails with a 'time out" exception at the
request.GetResponse() : …Unhandled Exception:
System.Net.WebException: The request timed outin <0x001b8>
System.Net.HttpWebRequest:EndGetResponse (IAsyncResult asyncResult)in <0x0007f> System.Net.HttpWebRequest:GetResponse
()in <0x003df>
Http.Requete:Main (System.String[] args)/ $
I installed the
mono-nokia_1.1.13-1_arm.deb package and copied the 'machine.config' file to the
'/var/lib/install/usr/etc/mono/1.0/' directory.This program works very well
on windows with mono-1.1.13.
Is it a bug? Did i miss
something? Does somebody have any idea?
Thanks,
Marc.

[maemo-developers] [maemo-users] Run SDL application under Fedora 4
Hi there, I'm at the beginning of development for Nokia770. My target is to build some existing SDL-based application for Nokia770. I did that surmounted difficulties :). But now when I run this program inside scratchbox under Fedora Core 4 it does nothing. I installed Ubuntu under VMware, installed scratchbox and maemo SDK there and run my program. It worked fine! I don't understand what is wrong. I tried to trace it using strace and I saw that the is a fork() and it's failed under Fedora with SIGCHLD (Child exited). Any ideas why? The program was compiled under Fedora. Environment: Fedora Core 4 / Ubuntu, scratchbox 0.9.8.5, maemo SDK 1.1 ARM.

I compiled your test program in two versions - arm4 and arm5 using the default toolchains built by bitbake + OpenEmbedded for the Zaurus sl-5500 and c7x0 machines respectively. Note that OpenZaurus uses significantly more up-to-date versions of libraries, etc. than the standard Sharp images, so this probably accounts for the difference in speed that you see below. If you want more info on the actual lib versions and patches then let me know. I ran these two binaries on my Zaurus sl-5500 and Zaurus sl-c750 (both running the latest OpenZaurus 3.5.4 flash image), and on my Nokia-770. The arm5 binary ran fine on the arm4 arch sl-5500, obviously there were no arm5 instructions included, but the times are slightly different - I don't know whether this is to do with background processes or something to do with the compiler (though I don't suppose the compiler really has much to do in this case.)
