I have Ubuntu 9.04 installed on my computer, and I need some sort of oscilloscope or function generator. In the Windows world, there is a free program here. Is there a similar program in Linux?
View 2 RepliesCan anyone recommend a PC oscilloscope that's compatible with Ubuntu? I need this for checking the waveform from an audio output.
View 1 Replies View RelatedI'd like to make a video of an ogg file going through an oscilloscope as it's playing. audacity (with enough zoom so that the wave can be seen as a wave and not a blur) could make it but it's too heavy and the screen capture software doesn't get the screen refreshes.... so I'd like to know if there's something that could provide more accuracy.

The script turns all the mp3 files into a m3u file.So far I have found the command "ls -1 >playlist.m3u *.mp3" this works great but what I want is to drag a file into the folder an album is in and then double click and it will run the command. I tried making a launcher and put that command on it, it seems to open up a terminal window but no playlist.m3u is generated. Could you tell me what I am doing wrong?

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

View 2 Replies View RelatedI installed ISE 12.2 DSP edition trail version and I have matlab 2009b edition. After a brief search I found [URL] this. But directory hierarchy is different in 12.2 than that of mentioned in that forum link.
I have installed matlab at /home/trans/Matlab and xilinx at /home/trans/Xilinx. Though I have sysgen_startup.m at /home/trans/Xilinx/ISE_DS/ISE/sysgen/util if I try to run sysgen by using command "./sysgen" I get error as
ERROR: Could not find SysGen startup script at "/home/trans/Xilinx/ISE/sysgen/util/sysgen_startup.m".
As per the above mentioned link I found sg_config at /home/trans/Xilinx/ISE_DS/ISE/sysgen/bin/lin and used command "./sg_config -install_to_matlab /home/trans/Matlab" I get message like this

I didn't understand the above error. I have chosen matlab workspace as /home/trans/Documents/MATLAB but I haven't pointed anything to that location.
So finally how do I set environmental variables at /home/trans/Xilinx/ISE_DS/ISE and how do I get sysgen to work? I installed ISE from the DVD which I got from xilinx
I'm running Ubuntu, with the Gnome desktop. I need a tone generator that will allow me to generate a timed sequence of tones. To be more specific, I need to be able to do something like a one-second 457.9 Hz tone, followed by a three-second 368.5 Hz tone. Is there anything out there that can do what I need?
View 8 Replies View RelatedI'm currently using OpenSuse 11.1 web server. This is bad since 11.1 is no longer supported. the reason why I am using it is because Function set_magic_quotes_runtime() was no longer being used. (so I was told)
That being said, is there a way to get Function set_magic_quotes_runtime() to function on the newer versions of OpenSuSE?
the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?

I am using Ubuntu 10.04 with Amarok 2.3.1 and I am having some problems with the Automatic Playlist Generator. I have not found my solution on these forums and I have searched google, and I am fairly new to using Amarok 2.
Every time I use the Automatic Playlist Generator, only 30 tracks are introduced into the playlist. Why is this? I don't want a limit to the amount of tracks which are selected.
I'd like to somehow connect a serial port to a headphone jack, plug it into the geiger counter and literally dump random noise from the geiger counter into the entropy pool used by /dev/random

I have left the system running at that point for almost 2 hrs, with no way to get past that. System isn't locked up. It has never done this before. How do I fix this?I have also tried failsafe booting, but it stops at the same spot also.
View 3 Replies View RelatedI have been using PHP to interface with MySQL and display information. Now, I want to printout reports; similar to MS Access does. I also need to run queries to do calculations and processes everyday. I normally have to do this by hand, but its taking too much time and I want to automate it. I would like to know if there is a free (or open source) linux program that will run daily scripts automatically alike a schedule and also print reports and/or output the data in a file (PDF, Spreadsheet, Document, etc). I also want to know if there is a free (or open source) linux program that will monitor these processes similar to Cronicle Redwood Explorer in windows land.
View 1 Replies View Relatedi could find is crunch2.9 password generator but at the moment it does not suport the function that i am looking for. My aim is to generate : 10-character combinations of the following characters (lowercase) 23456789abcdef with no more then 3 same letters repeates no metter side by side or within one line (sequence) so lets say
abcdef1234 accept
fabcde1234 accept
ffabcd1234 accept
which is probably permutation with repetable string ( where abc is not equeal to cba etc .so ti speak position does metter)
fffabc1234 not acceptable -----(3 same characters)
ffabcf1234 not acceptable -----( 3 same characters event thought not side by side)
so generally we dont want 3 same characters apper in same line.

View 2 Replies View RelatedI'm recompiling my kernel on a dell latitude c600 running lenny as I type, and it's taking forever, so far upward of 4 hours.I think I'm getting drivers for ever piece of computing hardware since the univac So I googled "a kernel conf creator" and got [URL]... Its a nice, clean method for finding what hardware your using... you just run lspci cpuinfo make xconfig and put in all the info yourself. So I was thinking: this is exactly the kind of dull, repetitive behavior that computers were made for. Is there a program that can find my hardware info, and make the.config itself, with very little user input?Or should I reinstall debian on another partition and steal the .config from it? Or should I man it up and do it myself?

I have never worked with databases before, and would like to create one to be a "workout generator." i.e. have a name of workout, list of equipment, list of exercises, and instructions. Then be able to search by any of the above parameters (for example dumbells and pullups) to get a list of options. I assume a relational database is my best option, but my brief looks at SQL etc they seem quite complicated. A GUI frontend and good documentation are highly desired. GTK is also preferred.

View 5 Replies View RelatedWe switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:
if sort-sequence = "descending" then
'sort -t~" -f +3.0f -4.0 +5.0r -6.0 -f '
else
'sort -t~" +3.0f -4.0 +1.0f -2.0 -f'
I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.
I am trying to make a random sentence generator in perl. So far I can loop it x times to make a fixed quantity of words, but I don't want to do that. Or I can let it go on until I hit ctrl-C :/
I want to have it so that when it reaches a word with a sentence terminating punctuation mark it stops.
My attempt to do that was with:
This is doing the woooosh text until ctrl-C thing...
Now however I am not sure how I can cut off everything after the punctuation mark (when it exists).
