Using AWN 0.3.9 on Ubuntu 9.10. AWN calendar applet returns the message "Unable to return calendar data from external source" when started. It is configured to read Evolution which is functioning normally.
View 4 RepliesI am trying to build an array with the column headers and the data like so:
PHP Code:
function query($query) {
$data = array();
$q = "$query";
$this->log->message("Manual query [$q], returning columns...");
$result = @mysqli_query($this->dbc, $q);
$this->selected_rows = mysqli_num_rows($result);
while($meta = mysqli_fetch_field($result)) {
while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
echo "meta [{$meta->name}]"; $data[$meta->name][] = $row[$meta->name]; } }
echo "DATA ["; print_r($data); echo "] <br />";
return $data; }
So I can select the data from the array like so:
PHP Code:
echo $data[col_name][row_num];
However when I dump the array I dont get the data I am expecting:
Code:
running select * from users:
meta [company_name]meta [company_name]
DATA [Array ( [company_name] => Array ( [0] => My company [1] => My details ) ) ]
I am implementing a simple serial protocol where my ARM9 board, running Linux is communicating to a slave peripheral board. The Master sends a 12 byte data stream and the peripheral board returns status in a 23 byte response. The serial port is opened in raw mode. It works perfectly on 44 reads; however, on the 45 read the data returned from the read() is incorrect. I've framed what's being sent on an oscope and it is correct.The coincidence is that 23 x 44 = 1012. It's as though the receive buffer is 1K and when I go past the boundary I get bad data. The read following the bad one is good again.I've tried flushing the buffer before reading but get the same result.Here's the port initialization code:
Code:
int initport(int fd)

In a nutshell: If the computer goes to blank screen (set that way in screensaver settings) I can hit a key and get the unlock dialog. However, if I walk away for longer and come back, I can't get the machine to wake up. It is powered on, but nothing comes up on the screen. I can't get other terminals by using ctrl-alt-FunctionKeys, either. I CAN, though, ssh into the machine from my desktop computer, and that works normally.I've installed 10.04 off of a live CD onto my Toshiba Satellite A45-S250 laptop. I had originally tried upgrading from 9.10 on the machine, however it wouldn't boot after the upgrade. The live CD also originally wouldn't work for me until I used a work around that involved adding "i915.modeset=0 xforcevesa" to the boot command line of the "Install Ubuntu" option of the live CD. This caused the CD to install, and now the laptop works properly.
The computer boots normally now, but on shutdown, the screen does go all "squiggly" before turning off.This doesn't interfere with the shut down or start up, though.I can post whatever logs or such that would help, but would have to be told what is relevant here. I've been using ubuntu on and off on this laptop since sometime in 2005, and have never experienced an issue like this.

There is a module A which is compiled with the kernel. I wrote an external module B which exported a symbol using EXPORT_SYMBOL.The module A now needs to talk with that exported symbol (function call). For that i modified A so that it includes the function call from B. However i now get unidentified symbol errors during 'make' operation as symbols of B are not present during kernel compile and A now kind of depends on B.
One solution is that make B part of the kernel as well. However, it would mean that whenever now i try to compile a kernel with a different source, i have to modify the config files and everything to accommodate B.Hence i am seeking a solution which does not include modifying the kernel.
Recently, I started downloading data from a website that shows houses for sale. My goal is to create a website on which people can find out about the pricing over the course of time and the length of time a house remains available. I have created a MySQL database, which is currently being fed each night. At this point, I have enough data records to start analyzing and mining this data.Now I have come to the part of starting a datawarehouse. I love to use a data modelling tool, like the one from MySQL. Yet, I have a hard time finding some documentation over data modelling a data vault datawarehouse using open source tools. Pentaho looks promising, but I need to keep this low-budget. So low-budget it needs to be free. MySQL Workbench has a moddelling tool as well. Yet it does not support a data vault scheme.Has anyone any experience in setting up a datawarehouse? Or in particular a data vault datawarehouse using open source tools?

View 1 Replies View RelatedCan not save data to external usb hard drive
formated and mounted on Ubuntu 9.10
visible on desktop /Dev/Sdb1
So I am working on a clients PC, and after I saved their data on an external hard drive I left it plugged in while I reinstalled Windows for them.....I HATE Windows. Stupid OS doesnt know any better than to just go deleting everything. Ubuntu would have known better than to delete multiple hard drives like that.
Anyway, please tell me I can salvage this data for my client? It was probably just reformatted. The data should still be there right?
I have a problem I don't know how to solve. Today I bought a netbook and while waiting for the new Ubuntu Unity release to come out, I thought of trying out Crunchbang instead of Windows that came with it. Browsing on my Ubuntu desktop machine, I found a guide for making Crunchbang live USB stick, and i followed the procedure. However, I made a very stupid mistake. The guide said I should enter the command:
sudo dd if=/path/to/iso/crunchbang-10-alpha-01-openbox-i686.iso of=/dev/sdX bs=4M;sync
where "of=...." part should be replaced with the name of the HDD. I forgot that I have an external HDD mounted and mistakenly copied the data to it.
After this, I cannot see the content of my external HDD anymore. Instead, i have this 620mb large Crunchbang-install device.
I know what I did was stupid, but is there a way to get the content of my HDD back? I have some valuable data on it.
I have a 1TB External HD that at the time of purchasing was used with my PS3 which only allowed FAT32 HDs. But now I am using it for other uses. I have came across the problem of the file size limit of 4gb that FAT32 has.The problem is I have about 200 GB filled of data on this HDD and wish to convert it to NTFS with no data being lossed. Is this possible and if so how?
Edit: BTW no Microsoft just Ubuntu
I am using Open office 3.2 with Ubuntu 10.10. Trying to get it set up to print out the Christmas address labels. To register the data source its 'FILE'> 'WIZARDS' then' ADDRESS DATA SOURCE.' But OO doesn't show the 'ADDRESS DATA SOURCE' at the bottom of the list, so I am stuck. Apart from that, I have had no problems with ubuntu and its working well.

View 3 Replies View RelatedI have Western Digital 1 TB external HDD. I had slackware 13 and it could copy data to it with speed around 30 MB/s (copy from machine to HDD) and it was cool. It's usb 2.0 as KInfoCenter says. But now in fedora 13, it's like 1 MB/s or even less (KInfoCenter still says usb 2.0). Any special mount option to set in fuseblk to speed it up? I mean something like blksize or like that?
Code:
/dev/sdc1 on /media/My Book type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
When installing Mint 10, I re-did some partitions, but forgot to turn off my old 30Gb external HDD, and deleted it's partitions. Which is the best software to recover it? It was partitioned with Windows software I think. Or should I use XP and freeware? Or else it will cost me $70-$80.
View 1 Replies View RelatedI specified the wrong out file while using the dd command to write a .img to what I thought was my thumb drive. Browsing the hard drive shows the liveOS folder but no longer any of the previous folders.I used PhotoRec to see if I could recover the files and it was able to recover files. So the files are still there. Is there a way to get these files without having to wait for PhotoRec to work on the 500GB drive, since this will take a while.
View 1 Replies View RelatedI have 2 external drives that I'm using for movies and they're both formatted to fat32. The problem I'm experiencing now is that some of the high quality mkv files are not able to be moved to the drive because of fat32's limitations.

I am running Ubuntu 10.04, and i recently purchased an tandberg LTO-4 SAS tape drive. I want to access it and backup data on it. Do I simply just connect plug it into the server,and I should be able to backup/transfer data to the tape drive? Or are there intermediate steps before I can do that.

I'm looking for a tool similar to synctoy in linux. For those who dont know what synctoy does is... its a simple syncing application that allows you to copy your data between multiple hard drives and keeps all copies in sync with the latest data. I'm specifically looking for KDE based tool if KDE based is not available then my second preference will be for gtk based app.
View 2 Replies View RelatedI have a 300 external usb drive which I have got when using windows and so is using a fat32 filesystem. I have since moved to linux only and am mounting the drive as vfat however I think I may as well convert it to ext4 if possible for (amongst others) performance and security reasons. The problem is I don't have a separate drive which would hold the 250gb of data temporarily whilst I changed the filesystem of the drive so I am hoping there is a way to format as ext4 whilst retaining the files?I know partition magic on windows allowed you to change between filesystems whilst keeping the data but does anything similar (and free! ) exist for linux?

View 3 Replies View RelatedI'm using Ubuntu 10.04 and am trying to use it to recover data from a failed External HDD (NTFS).
The drive failed with an accompanying smell of electric burning and subsequently was not recognised by Windows. It would recognice the enclosure, but told me that the drive had to be reformatted.
I removed the drive from the external enclosure and hooked it up to my PC with a power cable and USB to SATA connector. I can mount the drive in Ubuntu (eventually) and I've learned enough about BASH to navigate through the files on the drive.
Those that I can access I am able to copy across to my internal drive (VERY slowly, but it does do it) but a lot of the directories show up with an Input/output Error when I run the ls -l command.
Is there any way for me to be able to access these files or to recover them? Should I be trying a different technique rather than just attempting to access and copy the files?
I have an Aspire One with Linux operating system.
I have an external hard drive that I want to save data to from my Aspire One however when I try I get a message that the external hard drive is full.

I am assuming my problem is something to do with the ACER Aspire One
So I was trying to remotely access my XP laptop from my Ubuntu laptop. I read up on tsclient and rdesktop and tried both methods. For example, in the terminal, I typed:
rdesktop <host ip>
However, this came back with the following error:
autoselected keyboard map en-us.
ERROR: <host ip>: unable to connect.
After a bit of internet searching, I found the solution to the keyboard problem. I typed:
rdesktop -k en-us <host ip>
This yielded the following error:
ERROR: <host ip>: unable to connect.
No clarification, no explanation. nothing. Does anyone have any ideas?
I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?
Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?
i have the following challenge: i have a Bluetooth GPS device that i have connected to my linux notebook. but now i also want to use the same device (or better, GPS data stream) for my Navigation device (HP Ipaq with TomTom). make an serial port bluetooth service (sending) that my Navigation device can connect to. copy the incoming bluetooth serial port data stream to the outgoing bluetooth serial port.
i have already installed GPSD so i have the TCP port where the GPS data is available for everything on my notebook. but now i also want it to send it out through bluetooth.
1. is there someone out there who already did this?
2. how to make an bluetooth serial port service on Fedora 12?
3. how to copy a data stream from 1 device to the next device?
