Battery empty after charging

Anders Friberg — Wed, 08 Feb 2012 22:57:34 +0000

Hello! i have a problem with a N900 I just bought. Sometimes when I charge the phone, instead of being charged it loses power rapidly and after a few hours in the charger I end up with an empty battery. It doesn't happen everytime but maybe every tenth-fifteenth or so.

Anybody have an idea?

Best regards Anders

Using Anki deck with non latin fonts Anki

Anthony Alvarez — Wed, 08 Feb 2012 20:59:03 +0000

I am thinking about getting an N900 and using Anki on it to learn Chinese. I do not have a n900 unit to test with yet.

Does N900 require additional installation of fonts in order to display Anki decks containing Chinese characters properly?
Where can Chinese fonts for n900 be downloaded from?
How to display Chinese characters on n900?

Any clues appreciated. Thank you.

"easy" and "compatible" are pretty subjective terms to me.

Can Anki on Maemo Diablo render multimedia decks with embedded sound and images properly.

How easy it is to sync with Desktop PC?

I would have appreciated if you had at least provided any description or link what Anki actually is. ;-)

Assuming you talk about http://ankisrs.net/ , that page links to http://talk.maemo.org/showthread.php?p=965250 which is a thread about the N900 hardware only. For the N810 I'd try the packages at https://garage.maemo.org/frs/?group_id=863 , and hopefully http://talk.maemo.org/showthread.php?t=27742 helps.

If you choose "New backup" in the "Backup" application the first dialog defines the storage location. So the file is where you decided to store it.

Did you try to restore contacts from your most recent backup?

Also, try to create a backup, see if contacts were exported properly in the backup file. If so, maybe you can delete the contacts DB and restore it from that backup. I would backup the original DB before doing any of that just in case it makes things worse.

Re: Troubles with chrooted Debian

Pavel Řezníček — Wed, 18 Jan 2012 11:28:01 +0000

Hello Eero,

thank you for your response! So it seems that the default way Easy Debian is installed isn't the best one chosen, at least not the most reliable. It’s wonderful how complex problematics lie under the “simple” file image mounting and writing to it. Thanks for the detailed clarification. It’s really very probable that I used to run into entire memory consumptions and such critical situations. So maybe it isn't anybody’s fault or responsibility, especially not the kernel developers’. A safe solution for such an intensive image file usage might be pretty complex.

Have a nice winter day. Regards for everybody on the mailing list.

Pavel

Hi,

But What I noticed during my experiments is that the loop mount support is somehow bad. When Easy Debian was mounted from an image file, as I started an I/O-intensive or CPU-intensive task such as copying the contents of the image to the card,

Loop images aren't a good idea for several reasons.

Using them can take a lot more (kernel) memory than just chrooting to a directory with debian stuff

If device runs completely out of memory without it being cause by user-space processes that could be killed, or it requiring also SW watchdog protected things (like X server to be killed), device will be rebooted.

my device almost always ended up in a shutdown or reboot and huge filesystem corruption inside the image file.

That's fairly obvious. Journaling file system guarantee only consistency of the file system metadata, not file contents, and you're having two such things on top of each other.

Therefore meta data of the file system within the loop image isn't protected and gets corrupted if you've been doing file system modifications inside the loop image just before reboot.

For such modification not to be corrupted on reboot, they would need to have been first synched to the image itself by the FS used inside the image, then synched to the real media by the file system on where the loop image itself resides.

Yes, even if I ran /rsync/ with the highest nice level. This is something for the power kernel developers to consider and think about. (But keep in mind I work with the stock kernel.)
