RSS feed
Hey guys n gals - this is request #2 (the first was through the RSS feed TBH and may have been missed). Since I migrated my site to a new server and new software a few weeks ago, the Maemo portion of my RSS feed is no longer available as a separate feed. The Maemo website has picked up the 403 redirect to my new server and is feeding all my blog posts and not just the Maemo related stuff like it used to. The RSS link is not part of my maemo.org account, so I can't disable it myself apparently. If someone would be so kind as to drop the maro.net URL then the rest of my open source and life related posts will stop showing on Planet Maemo where they don't really belong. When I can figure out how to get an RSS feed on just one topic back out of Drupal, I'll submit a separate RSS link later that will be Maemo only. Thanks! -- Tony Maro http://www.ossramblings.com/ ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
Computerworld article
Linked on Slashdot, so likely others have seen this already... http://www.computerworld.com/action/article.do?command=viewArticleBasicarticleId=9039659 From the article: -- The Federal Communications Commission *recently approvedhttp://tinyurl.com/3yhfzb * a new minitablet, nonphone device from Nokia that supports Bluetooth, WLAN and GPS. The approval was branded as confidential, so only the sketchiest of details are available on the product, which will almost certainly ship this year. I'm not sure Nokia has the right stuff to compete in the nonphone market. For starters, the company has trouble focusing on individual products and tends to scatter its energy and resources across its massive line of devices. The future king of tiny mobile computers is going to need vision and focus. Go ahead and take Nokia off the list of contenders. -- Personally I think he's got it wrong. I've noticed with tech companies (including Microsoft) that third time's the charm. I think Nokia has touched into the power users with the open-sourciness (hehe) of Maemo and gotten enough good feedback that the next revision will be a big hit. Adding GPS would be awesome if still economical, and if you guys listened to everyone about sync capabilities for contacts and such, there's no product that could really compete in my opinion. Although I think multitouch solid screens similar to the iPhone might be nice ;-) At least the solid part. I'm always afraid I'm going to damage my LCD. I mean let's be honest - I'd give up my RAZR in a heartbeat for a good old solid indestructible Nokia phone that doesn't misdial every time I call someone. The brand still carries a lot of weight for me.

Python + GTK event question
I know this is likely more of a Python + GTK question, but I'm banging my head against the wall and was hoping someone could help. I've written a blog post about it as well: http://www.maro.net/ossramblings.php?itemid=369 It's regarding the GTK kinetic scrolling widget I released last week. Basically, without getting too deep into the code, here's what I do: Create a kinetic scrolling widget. It's a descendant of a DrawingArea. I extend that and I allow the new component to hook to some of it's own events (probably a bad idea, but oh well) so that the new component knows when the user clicks or drags. It watches button_press, button_release and motion_notify events. When it's realized, it starts a timer for drawing itself - kind of a framerate timer. In the button_release_event, I might pass a callback to the application telling it the user clicked a selection. In that callback, I destroy the widget and create a new identical widget. I then show the new widget, with a new list. When the widget gets the realize event, it starts an internal timer (which I remove when the widget is destroyed) using gobject.timeout_add(75, self.updateme) I've tested the updateme function and it takes about .04 to .09 seconds to execute. Because timeouts don't block other things and don't try to make up time, I don't get a solid frame rate, but I should get at least .075 seconds between each event. Now, when you run the first widget, everything does fine. I get all the mousemove events, to the tune of 1 to 15 between each tick. I set a print statement in the updateme event so I get a line printed every tick, and you can watch them fly by. When you click an item, it triggers the callback in the application that destroys the widget (which removes the timer just fine). Then new widget will then get realized and works almost as expected, except that you can visibly see that the updateme routine is being called at about half the speed that it was called the first time, and you only get one pointer motion event between every tick. This means that as much as 30 seconds after you let go of the screen, the app might be getting notified of pointer motion events still. Have I gone wrong at some basic level somewhere? The widget creation is done identically both times. Here's the sample code from the application (not the widget): http://pastebin.org/2151 The only thing I can think of is that it must have something to do with deleting and creating a new widget from inside the callback of the first widget. If I start the process all over again with the same instance of the app, it's back to normal speed with the first widget, so it's not something that's hogging CPU. In fact, top output shows almost no activity during the slowdown. -- Tony Maro http://www.maro.net/ossramblings.php ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
I wish you could see what was running before Nokia dies
Last night I charged my n800, then did a little web browsing. As always, I went into offline mode, then locked the screen and placed it beside the bed. When I woke up, the battery was stone cold dead. I wish there were a way to know what might have been running that killed the battery... I wonder how hard it would be to write an application that watches processes for high usage and logs every 5 minutes if something is hogging the CPU. Maybe have it live as an icon by the battery meter or something... -- Tony Maro http://www.maro.net/ossramblings.php ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Alpha test of DragonFear for download
http://tony.maro.net/ossramblings/dragonfear.php Definitely an Alpha because you won't get much gaming enjoyment out of it ;-) I did make a .deb though. Things you can try out: Auto-download of media files from the Internet Kinetic menu navigation Character Generation New game creation (it asks for what game to start but won't let you choose one - don't worry.) Movement through the map (very small map I hard coded) Very basic combat, but no spells or magic items to use View your character's inventory with the fullscreen toggle button Return to the menu with the Menu button (of all things!)

You can also use the environment variables MMC_MOUNTPOINT and INTERNAL_MMC_MOUNTPOINT, but then you have to make sure that they are always set correctly in your environment. (I don't think using environment variables for this kind of system information is a good idea.) Agreed. Especially with the numbers of morons like me that are likely to screw those up ;-) The device files are not constant like this: the internal card might be /dev/mmcblk0 or /dev/mmcblk1, as far as I understand. Someone with better low-level knowledge please correct me. I had thought this might be the case, especially since my /dev/mmcblk0 goes to /media/mmc2 and /dev/mmcblk1 goes to /media/mmc1 on my device.

OSSO Media Server and system pauses
Okay, so I ripped out gstreamer and put in OSSO Media Server code. The thing I've noticed is that there's a distinct pause of about 1 second in my code when you start a new song playing. I didn't have this issue with gstreamer (though the other issues with gstreamer far outweigh the new problem.) Without using threads it was nearly a 2.5 second pause, so using a thread helped. For a media player app this wouldn't be a problem, but for a game, it's murder. I've run cProfile and it says there's only a .02 second delay in the send_cmd function, but there's a definite pause in user input of about one second.

This kind of damage can be repaired using the Disk Manager on Windows XP or 2000. If you use this to reformat such a device, it will come back to life quite successfully (but be prepared for a bit of a wait while the Disk Manager decides that the device is not properly formatted and that it can't therefore show its current format).

It's much easier to just use OSSO Media Server via dbus and let *it* deal with gstreamer for us. I'm beginning to realize this about gstreamer as well.

Finding the mmc cards
After our thread some weeks ago regarding reading the serial number from a MMC card, I've since implemented detection of the MMC card's presence by the existence of those same files. I know my solution works on my device perfectly. I figure it's probably a bad decision, because the architecture could change somewhat with the next hardware or software release. Can someone tell me, is there an approved / documented way of identifying the location of any MMC cards currently installed? I've noticed you can't simply look for /media/mmcX because that directory will exist even if there is no card inserted. Also, what determines MMC1 vs MMC2 as the card's path for internal/external? Is it possible these paths would change at some date? I know some Linux distro's with SATA drives had a problem with the drives changing their /dev/sdX path every reboot. I know that MY Nokia isn't doing anything similar, but I figure it's possible that my /media/mmc1 might be internal, but for someone else it could be the external slot - or maybe in the next hardware revision or something. I did find the alias names located in the /sys/ path that specify internal is for one and external or removable or something for the other. Also, are the names and paths the same for the 770's? Since I have an n800 I don't know. I'm hesitant to read too much data from /sys/ because it all looks _so_ Maemo-specific I wonder if I will tie my code too closely to one hardware revision. Just looking for the most _compatible_ way to identify if/when and where a media card is present. And as usual, from Python.

Python and GStreamer
I've been trying to figure out how to use gstreamer to play audio. It
works, but sometimes it will randomly freeze my application when I try to
start an mp3 file playing. I'm only using two mp3 files and they both work
at other times (like after a reboot) so I know it's not specifically the
file.
Sometimes I'll start my application which calls the start method of the
SoundControl class below - and no sound starts. Then, when my app tries to
stop the music, everything freezes up. It always seems to freeze things
when I call stop
After doing this, my application refuses to work at all (always freezes)
until I reboot my n800.
If anyone has any ideas, I'd greatly appreciate it. Yes, I know there's
probably more optimized ways to do some of what I have in this class, but
it's grown as I've learned gstreamer, and I haven't stopped to refactor it
yet.

Re: Controlling virtual keyboard from Python application?

There is no easy way to do that, but you probably could try to emulate the triggers (e.g. the stylus or finger tap on the text entry), so the Hildon Input Method wakes up and invoke the input method based on the trigger. I would propose that this is a bad idea. I use a Bluetooth keyboard about 40% of the time, and Maemo is very good about NOT popping up the keyboard when my BT keyboard is active. That said, I have noticed that something in gre-calendar interferes with the pop-up keyboard. You can get the smaller keyboard but not the finger keyboard when entering a new event. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
How to keep window on top? (python)
I'm a noob at both Python and GTK so forgive me if this is a silly question. I've got a modal window I'm creating, and I've tried doing set_transient_for but no matter what I've done, it won't stay on top of the base application window. You can easily pick the app window from the taskbar and switch to it, even though it can't get input. If a user does this by accident, it leaves the impression that the program has locked up. Can someone point me in the right direction? Or does busybox not support this? ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

dbus and startup script

Re: dbus and startup script
I've got all of that in place as well. It didn't start doing this until I
wedged the shell script in front of the startup of the Python.
I took out the shell script, replaced it with the main python script, and at
the top of the main python script I placed:
import sys
sys.path.append('/usr/lib/thummim/')
That way it could find it's include files stored in the other directory.
Everything works fine again, including the dbus integration and taskbar
icon.

The loading indicator should go away when you create the HildonProgram

working, check the dbus service file as missing it could be (I'm not

Re: Obtaining flash memory serial numbers on Nokia N800
On 8/12/07, David Hazel [EMAIL PROTECTED] wrote: OK, so far I haven't had a reply that really answers my original questions, so let me rephrase them: I'd tend to disagree, but let's go on ;-) 1. Given a full directory path, how can I determine FROM WITHIN AN APPLICATION which storage device (memory card) this corresponds with? In other words, starting with something of the form /dir1/dir2/dir3/file, how can I identify the storage device that this resides on? Well, that one would best be determined by reading the output of df or mount I would think. Because the Linux file system is so flexible, there may not be an actual device associated with a given path. Some of the paths in the file system are actually output from running applications. Others might be mounted across the network using any number of network file systems. For instance, the /proc directory doesn't really exist on a Linux hard drive so much as is output by a program running on the machine. So when you say you want to find which storage device a path corresponds with there may not be an answer because the question is wrong. Read on for more info... 2. Having found the above, how can I then find that storage device's serial number? (Again, FROM WITHIN AN APPLICATION) Um, actually that was the answer everyone provided. No need to yell - that's generally what gets most Linux advocates bristling and starts flame wars. Just read the text file at the specified location. Where we said cat XX, cat was just meaning dump the contents of that file to the console, so you could just open that file like any text file and read the serial number out of it. That's Linux 101, but certainly is alien to anyone who has done Palm, PocketPC or Windows development. So in Python for instance, you might do: mypath = '/sys/devices/platform/mmci-omap.1/mmc1*/cid' srcfile = open(mypath,'r') myserial = srcfile.readline() srcfile.close() # tada! no need for any include's either. Nice and simple. You can use the same method to find the type of processor in the device, how much memory card space is in use, and untold many other tidbits of cool information. Keep in mind, Linux aka Unix was originally designed around everything communicating to each other through what is basically console I/O. It's a really neat system when you think about it. This means there's no special API that needs written or header files that must be available for each language in order to access this information. Other aspects of the Linux OS are actually changed just simply by writing to these fake text files in your directory structure. These fake text files are just the communications medium between applications. And that's a Fact. ;-) Fact: I can programmatically determine an SD card's serial number on a Windows Mobile device. Therefore I expect this to be possible on the Nokia 800 as well. Sure, just read it from the file system as described above. Linux provides the /sys/devices (or on a desktop normally /proc/whatever) file system to make it easier to do this, so there's not even an API you need. Just read the settings you're looking for from the OS supplied text file. Fact: I can programmatically map a directory path onto its corresponding device under Mac OS X (which is BSD Unix with go-faster stripes). Therefore I expect to be able to do something similar on an N800 running a variant of Linux (which is Unix-like, right?). If you're talking about mounting sure, but you'll need to do it as root for security reasons. If that's not what you mean, you'll need to clarify. Someone who's a C programmer might be able to expound on my comments and give other options as well. Also, on a side note, you sent your response directly to me and not the list, so I'm submitting it back to the list as well assuming it was an oversight on your part. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Finally, my first project
I just released the first beta of Thummim Reader: http://tony.maro.net/ossramblings/thummim.php It's a scripture reader that will read any text file, and also supports an index file that points to verse locations. You can highlight text in any color, add notes that click through to verses, and add bookmarks that link to any of your documents. It's very easy to make your own index files, and I also have a utility for your desktop computer that will download the King James Bible and other documents from lds.org. I don't distribute any documents so I can't inadvertently violate a copyright. I couldn't have done it without the help here!

This is very useful if you're just trying to tell one card from another. For instance, if you're storing a database on a specific card, have your application recognize when that card is in your device verses the card from your camera, or another card with a similar database. Normally you would get this from /proc/scsi/ or similar, but there doesn't appear to be any entries for it... ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Loving the development
In the past four days since I got my n800 I'm thrilled with it. I started programming in python two days ago (I'm a Pascal PHP guy,) and I just finished my first working program - er if you can call it finished. It's a Bible reader that allows you to highlight sections of text. it also allows you to jump to books, chapters and verses with just a few clicks. It stores the text in plain text rather than compressed, and uses two secondary files for storing your markups and the pre-supplied index file that points to the start of each verse. It will also open standard text files with no index file and still allow you to add highlightings. I took the completely open and oversimplified road with the file formats because I was so frustrated at looking at the file formats used by all the other palm readers, not to mention trying to figure out the sword file format. Other than the fact that loading the indexes for the Old Testament file takes about 5 seconds, it's very fast and uses very little running memory. I designed it to only read in the page of text you're currently reading from the large text file, so you don't have to load the entire text into memory. Next I've got to add some file management features (currently you file+open the document you want) and some note taking features so you can create your own topics that link to specific areas of the files. Probably late next week I'll release it for download. I'm running it from xterm right now, so it's still not ready for prime time ;-) ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
