I am looking for a new programming job (having programmed video games in C++ for three years), and, it occured to me that I might be able to work on free/open-source software and get paid to do it. [My wife is supportive of the idea, too!]

I just don't even know where to begin, and figured that if ever there was an on-topic post for an off-topic forum, this is it wink.gif

I expect that there are not many paying F/OSS jobs, but there must be some. (Right?) It seems likely that one could work from home, provided they had a decent computer and a broadband connection. I've done some google searches (and will do some more) but haven't really found good information yet.

Unfortunately (no, please don't look at me like that!) I have not contributed anything to the F/OSS movement, and am unfamiliar with software development on linux. I know that this is a large and poorly specified question, but, does anyone have any insights on how to best (and quickly) develop the skills I need to be a F/OSS contributor (even if there is no job to be found)?

As you can see, I don't even really know which questions to ask, or if it is at all reasonable to look for gainful employment in this sector.

I appreciate any insights.

Here is a handy script that I wrote to make it convenient to start X applications from a terminal, which is really handy on the Zaurus, as well as being useful on a normal PC running X windows.

The script is as follows, and is attached:

# Queue it up, quickly and quietly
# Runs a program in the background and suppresses all output.
# Particularly useful for starting X applications from
# a terminal.
# Useage: q some-application some parameters
#     ex: q dillo myfile.html
# Written by Armagon, 2007-04-05
# You are welcome to use this however you see fit.

$* > /dev/null 2>&1 &

After downloading the attachment, you will want to install it (as root):
cp q.txt /usr/bin/q
chmod +x /usr/bin/q

Well, as I haven't seen this in my searches, I wonder if it is specific to my Z.

I just flashed my C1000 with pdaXii13. I believe it is the latest and greatest; it identifies itself as "pdaXii13 build5.3.2 'Sally'" if I exit X-windows and try to log in.

Unfortunately, I don't have any sound output.

When I try to load up an ogg in XMMS, I get the following message:

Couldn't open audio

Please check that:

Your soundcard is configured properly
You have the correct output plugin selected
No other program is blocking the soundcard

If I do an 'lsmod', I see that the following modules are loaded: mousedev, pxa27x_bi, storage_fd, usbdcore, usbdmonitor, usb-monitor, sharp_mmcsd_m, bvdd. Noteably missing are any sound modules.

I tried to run alsamixer, but it isn't installed; indeed, I don't appear to have any *alsa* files on my system.

One last thing. Among the startup messages, the following are displayed.

IrCOMM protocol (Dag Brattli)
cramfs: wrong magic
FAT: bogus logical sector size 381
jffs2_scan_inode_node(): CRC failed on node at 0x05374fec: Read 0xffffffff, calculated 0x0bee2a6b

If it matters, when flashing, I fixed the 64MB limit, and set the root partition to be 85 MB.

Any ideas what is wrong or how to fix it? I'm happy to reflash, as I've not installed anything yet.

I'm wondering how to move data between my Akita (C1000) and a Windows XP box (such as those used at work.)


It appears that TCP/IP over USB not working with a C1000 and XP is a known issue:

QUOTE(papercrane @ Mar 29 2006, 12:32 PM)
The Cxx00 doesn't talk to Windows correctly yet. Richard Purdie "has some hints" which should make it work but he hasn't had time to implement them yet. :-/

Mass storage device

It appears to me that the mass storage device doesn't work without patching the kernel, and that's really not something I want to do. [I did play around with trying to modprobe g_file_storage with different devices, including a special file, as described here, but my PCs (running Linux or Win XP) weren't happy about it, and continually reset the usb connection. [I can add more details if it helps.]]

Other alternatives

Sigh. My SD card is ext2 formatted and running an altbooted GPE; I don't have a CF card.

... Wait a second ... I have a FAT formatted SD card in my camera ... and sure enough, I can write to it from my Z! [Wow, using that to transfer data does rather strike me as (almost) ... abusing ... the camera!]

Well, that's probably easier than trying to force my 500 mA max USB to serial port converter to work (not to mention the fact that it means I don't need to make a null-modem cable) (although, perversely, if I had the time, I think I'd give it a try. Surely normal communications use nowhere near 500 mA! I just posted another question finding out if it is safe to use or not.)

The only other option (barring really esoteric things like playing back and recording data encoded in audio) I could see was IRDA, and my Z is the only device that uses it. [Hmm... Still want to try to make it work as a TV remote control...] And no, I don't have any bluetooth or wifi hardware at all.


My questions, then: am I right that the first two options do not currently work (and are they being addressed? -- ack... I didn't see them in the bugtracker. Is there a guide for writing up OE bugs anywhere, or shall I just wing it?), and, um, was there any communication option that I've overlooked that might work for me.

Thank you,

I'm running OZ on my C1000, but I think this is a fairly general question.

In kernel 2.16 and newer, if a USB device requires too much power, it is not enabled. 'dmesg' output might look like:

usb 1-2: no configuration chosen from 1 choice

To find out how much power a USB device wants, one can invoke:

lsusb -v | grep MaxPower

My card reader wants up to 250 mA, and my USB to serial converter says it might use up to 500 mA!

Post #3 on this ubuntu forum thread describes a work-around.

So my question is, is it safe to do this? [Also, I assume that people who are using kernels before 2.16 could well ask the same question, even if the device isn't automatically disabled.] Are the manufacturers of these USB products giving a high margin of error? Can a high-current device damage a Zaurus, or will it simply shorten battery life or just plain not work?

Thank you,

[Edit]. PS. Does it make any difference if the Z is plugged in or not?
