Ubuntu :: C Code Next Number In Series
Sep 17, 2010
I have been looking at Open Office calc to work the next in a series if non-linear numbers, and calc does do a very good best fit and shows the equation. Just what I want. I now want to programme this into a C routine that I am writing so that the programme will both look-up what it can from a samples database, and extend them forward where it does not have enough samples. (I'm trying to understand some correlations). My thought at present is to take the Ooo calc formula and write it into my code. Before I do so, I wonder if anyone knows of any non-linear solver routines written in C that I could just plug in? I'm trying to do a best fit from only about 6 very accurate floats which graph like a curve.

For reasons I can't even begin to figure out, the number pad does NOT work.i can get the num lock light to come on, but pressing the keys there produces no love at all. Right before I installed F10, my F8 x64 had been working flawlessly for a VERY long time and I have been able to verify that the keypad still functions both with the M$ Windoze Vi$ta virus and a live Knoppix CD.Since this is the first time I have had this issue, I don't even know where to look to consider solving this.
I did try the System->Preferences->Hardware->Keyboard and all of the HP layouts listed there, but I still can't get anything more than the Num Lock light to come on and go out.

I have a problem with the latest Fedora. Installed it cleanly on a machine with Gigabyte H55M-S2 with Intel Core i3. There seems to be no sound and I checked to see if anything is muted but is not. The manual says that the sound chip is ALC888B so this could be the first problem. Any ide how I can make it work? Here is a dump of some things on my system.
Code: [weaz ~]$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
[weaz ~]$ uname -a
Linux EarthwormJim 2.6.35.6-48.fc14.i686 #1 SMP Fri Oct 22 15:34:36 UTC 2010 i686 i686 i386 GNU/Linux

I recently used scalpel to recover .doc files. I only need to find just one file, but scalpel retrieved thousands and thousands of them, all titled after a sequence of numbers. If I could only search within them all for a single word I'd be able to identify the ones to check out vs. the duds immediately.

I have a problem that I'm trying to solve with a lack of some network knowledge. At least I thought I knew them.This are my machines:
1. Ubuntu Desktop - OpenSSH
2. Asus WL520 Router (with Tomato firmware) - DropBear
3. DNS323 Server - OpenSSH
4. Windows 7 Desktop - Putty
@Home
(3) DNS323 server is WAN accessible (via ssh)
(4) Windows 7 is not WAN accessible.
@Office
(1) and (2) are both not accessible via WAN.
(1) and (2) are in the same network (192.168.1.x)
Code:
(192.168.1.5) (192.168.2.1)
[Ubuntu]----[Firewall]----[Internet]----[DNS323]----[Windows 7][code]......

The correct 96-series nVidia drivers for 10.10 weren't issued until several months after that release. Now they do not work for 11.04 and no one on the Ubuntu forums seems to know the correct information about work arounds, I stumbled onto the X.org drivers but I do not know if I have them installed correctly or not. I am getting 1280 x 1024 at supposedly 0 Hz but probably 60Hz. It is a good work around as OC is used mostly for text editing and e-mail.

First problem is that there does not seem to be any Catalyst Control Center available for this driver. Is there one anywhere for Linux for this driver? The graphics card appears to be constantly at 99% usage at all times when simply sitting at the desktop. Is there a way to bring this down to virtually no usage like it should be at?
The display area on my monitor does not extend to the edges. In Windows, I can simply scale it to 0% to overscan in order to completely fill the screen inside the Catalyst Control Center; in Linux, I have been unable to do so with a monitor. Is there any way to scale the display area to completely fill my screen?

Trying to get this working via wireless connction with 11.04. So far I've managed to install (correctly I think) hplip-3.11.5.run. If I select what I think is the correct option, when it gets to the configuration proceedure, it asked me to temporarily connect via usb. However it doesn't see the usb connection when prompted so I can't complete the configuration. If I configure as a usb printer, the first option, it does see the connection and it prints a test page fine. Tried the other options as well but no joy. Wireless connection to windows laptop and main windows pc is working fine.

I have the samsung LED 7100, and I can't figure out how to connect it to ubuntu. The way it is supposed to work is I share one or multiple folders that are shared and I can browse them trough the tv since it is connected to my network via hard wire. In windows I do that in 1 minute, but I love Ubuntu so much better when it comes to anything else.

I got a new Sony F series laptop and struggled thru getting the video card to work, the wireless card to work, and the volume to work on 9.10. The brightness controls have stumped me though. The screen is on full bright and the brightness controls (FN+F5 & FN+F6) make the applet display change but the actual screen brightness does not change. I have also tried the brightness applet in the panel and that also has no effect on actual screen brightness.

So Ubuntu had been working great in Lucid, and when I upgraded to Maverick the support for my graphics card stopped. It has the proper driver ("ATI/AMD Proprietary FGLRX graphics driver") active and fglrx, fglrx-amdccle and fglrx-modaliases are all at 2:8.780-0ubuntu2. I also have the xorg radeon package installed. Yet, whenever I try to enable desktop effects (to get compiz to work) it says that Desktop effects could not be enabled.

This little darling will check the r/w performance of HC memory cards....in some fashion or other. As [mis-] fortune would have it, I own a failed TRANSCEND 16G SDHC SERIES 6 memory card. Posting to the HMC-150 video camera users group on the diagnosis. I really, really need some expert feedback on the interpretation of the analysis generated by the Drive Utility. Posting attached screen shots of: LS-1 Bad TRANSCEND SDHC and LS-2 GOOD TRANSCEND SDHC.

I would like to install the new Ubuntu 11.04 64bit. I first booted from usb to see how the new release behaves on my laptop(sony vaio eb3m1e). The thing that does not work as it should is that the OS can't detect the GPU which is an ATI radeon 5650, when i click the additional drivers icon in order to install the proprietary drivers I only see the "no proprietary drivers are in use on this system". How can I make the OS detect the GPU?

Lexmark Z730 Series printer. I know it's an old model but I'd like it to work with my Ubuntu 9.04. Is there a way , technically, of configuring it manually, using a set of commands...some guerilla tactics method...to get it to print. I've searched high and low for the Ubuntu version of its drivers, but in vain.

I would like to use VIM to add something to the end of a series of lines. Ideally I could do something like add " X" (with a space before the X) to the end of lines 1-40 and 50-60 in a single command, i.e. ideally I could have a break in between where I didn't add something. If that's not possible just adding to 1-40 and 50-60 separately would work too. I would be using bufdo to do this, but my understanding is that anything you can do in vim you can use with the bufdo command.

I recently received my new multimedia laptop - an HP Dv7. I proceeded to install Ubuntu 9.10 on it and I've had no end of troubles with the sound card including, muffled sound - seemingly only coming from the LFE channel, only stereo controls in pavucontrol, failure to send sound out the HDMI port, headphones not working and not cutting of the speakers when the headphones are plugged in.
I believe that all of this will be solved if I get the appropriate driver for my card. I have searched around and sound in particular has tons of posts from many people all with slightly different problems, solutions and hardware. None of the solutions seem to be working. Also I just tried booting from the live CD and the sound is the same - no 5.1 and just muffled sound. I think my sound card is just too new and there doesn't exist a proper driver for it yet.
Here's what I get with lscpi:
Code:
% lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
01:00.1 Audio device: nVidia Corporation Device 0be2 (rev a1)
