Ubuntu :: Algebra Plotter And Solver For Intersections?
Feb 2, 2011
I'm looking for a graphing calculator program for Ubuntu that easily solves for intersections, MIN and/or MAX. I've found plenty of calculators that graph multiple functions but my course has sections designed for graphing calculators and I don't want to purchase one if I can do this using Ubuntu.I know there are a few complicated math solvers (Octave for instance) that can do it, but I'd rather not have to learn yet another programming language! I'd love to have a button for those solutions.
I'm trying to get an old Roland pen plotter to work on Ubuntu.So far I can't even see it. I'm using a Parallel to usb cable, which from other post may be a problem. I think the plotter works, it turns on and things move about as if getting ready to do a job.
Are there any Computer Algebra Systems in the Ubuntu repositories that are GUI (and preferably GTK+) based and open source, as well as capable of graphing (and in 3D)? That being: A complete FOSS competitor to Microsoft Student.
I've installed pingplotter freeware on LinuxMint8 Helena thru Wine, but while it installed and runs successfully, does not seem to ping any host.I'm literally addicted to this program in WinXP, cos my pathetic Wireless Broadband ISP keeps going up and down, so I need to constantly know what the status of the connection is.Has anyone had any success in making ping plotter freeware successfully ping in Linux?
I'm new to Linux, so I decided to try using Wubi to get started. THe problem is, when it finished installing 10.04, I got this message: OSError: [Errno 13] Permission denied: u'C:\ubuntu\install\ubuntu-10.04-desktop-amd64.iso' Is there any way around this? It might just be that overly restrictive thing called Vista (which I have the bad luck to be using). I was considering getting a USB drive for Ubuntu anyway..
I recently got interested with with OS.. So I downloaded wubi in Ubuntu website. I opted for the Ubuntu Netbook Edition as am using a lappy. However, halfway through finishing download I got an error. The log shows:
What is the difference between the Ubuntu Installer for windows and the Ubuntu CD image? If I use the ubuntu installer for windows, does it have the capability to partition my drive, will it enable to share files with windows etc or is it just a way not to have to burn a CD. Just curious, the exact details of the installation files were not made clear on the website. Note: Windows Version: XP, 32bit, SP3. I have not partitioned anything yet.
I have windows 7 installed on Disk2 (according to windows Disk Manager), and I installed ubuntu 10.10 on Disk0, choosing the dual boot option at installation.
However, grub does not load (presumably because its on disk0 and my machine appears to boot from disk3), so the machine goes straight into windows 7.
I'm currently running off of my live-cd, and after spending 4 hours of my life trying to fix this myself, i figured someone out here has to know how to help me. Basically, i wanted to try linux, then liked it enough to decide to put on one of my usb-drives (320g adata nobility NH92), and i couldn't get it to boot anything but windows w/o the live-cd, which would then boot the live-cd, lol, in other words, i couldn't get it to boot at all from the external, even though i had changed the setting in my bios to boot from usb first, and tried manually selecting boot from usb and all that fun stuff.
Sooo... eventually i decided it might be a problem with the bootloader, and while i'm not exactly sure at this point what i have done to my computer, all i can successfully boot is the live cd. When I try to boot w/o the live cd, whether i try to boot from my internal (windows) drive, or external, all i get is a device not found error.I think i could fix it if i had windows recovery cd's (i'm running xp, btw), or installation cds, but... unfortunately, they died in a terrible accident. So i have no cd's at all for windows. :/
I have been running Ubuntu 10.04 under Windows 7 (Is this call WUBI?) without any problems for a while. My other machines only run Ubuntu (9.04 & 10.04). I decided to give it a try to the latest Ubuntu 10.10. After going through the successful installation and then rebooting, I am getting the following error message once I select 'Ubuntu' in the boot up menu right after the BIOS screen: Booting ' Ubuntu 10.10, kernel 2.6.35-25-generic'
I'm wondering if this is even possible. I've searched high and low and have yet to find and answer to this particular setup.
The setup: Router is in another building. Desktop connected by WiFi Laptop connected by WiFi Both the Desktop and the Laptop are in the same building together. About 5' apart.
SSH server is setup on Desktop FreeNX client is setup on Laptop
So they can connect just fine via WiFi for remote desktop control of the Desktop from the Laptop (so SSH and FreeNX are working).Is it possible to connect the 2 pc's directly to each other by Ethernet cable AND transfer files between them by Ethernet while still being connected to the Internet by WiFi on them both?Or would the WiFi have to be disabled while using the Ethernet connection?Neither has a Gigabit Ethernet NIC so I know it would at least require a crossover cable or another router to connect the 2 by Ethernet cable.The idea behind all this is to be able to transfer files between computers quickly by Ethernet while the computers are still busy doing other things on the Internet by WiFi.
I've been trying to find what would be the lightest ubuntu or ubuntu based distribution, I have an older PC I'd like to get up and running again, and would prefer something that works pretty quickly on it (for basic web browsing and other things) the specs are:
1. I accidentally wrecked a previous Ubuntu installation so I decided to re-install via the Ubuntu disk. Unfortunately Ubuntu doesn't let me override previous Ubuntu installations...
2. Ubuntu Maverick Meerkat is due to released in about 3 weeks. I want to install it via a clean install.
3. So can anyone tell me how to remove both Ubuntu partitions safely. I am currently running WinVista with Ubuntu Lucid Lynx. I know I have to use something like this to erase GRUB2. Can anyone give me a good tutorial?
The scenario is as follows - I will be moving across the country and my desktop will stay here powered and online, while I move with a laptop. I need a way to connect to the desktop for file streaming(music and movies) as well as using the virtual machines. I have thought about SSH and VNC.I need something failsafe. That's priority one. I won't be around to fix it if it breaks. I can set the computer to come on in the BIOS at a certain time if the power went out. But if I can get in remotely the whole setup is useless.SSH only provides terminal use, correct? So if I chose that route I would be able to access the computer via command line and play music and movies with mplayer and such, correct? But I would not be able to run the virtual machines? Because there will be no GUI, right?
I have been playing with Vinagre and Vino through the host and guest of a virtual machine and I cannot get it to connect. Is there a better application? x11vnc? I have forwarded port 5900 on the router and have upnp enabled. Got a better remote desktop suggestion?I would like to run this setup headless.(no monitor) I also would like to run it without a gpu if that is possible to make it more energy efficient.Both computers are 64 bits and will be running Ubuntu 10.10 and soon 11.04.Are these crappy ideas to begin with? Should I go another route to get my files and access the virtual machines?
After a reinstall of 10.10, I am able to turn on file sharing and so I set up a shared folder.
Windows Vista can see this folder but in my network place, there is only one icon, and it's a "Windows Network" icon. Upon clicking on that, I can see the local network, "Rompus Room".
When I click on Rompus Room, nothing happens for a while, then I get a message saying, "Opening "ROMPUS ROOM". Then I get the final message, "Unable to mount location", followed by, "Failed to retieve share list from server"
I was running 9.10 in LiveCD mode and was unable to get online. Went to System>Administration>Hardware Drives and found "Broadcom STA wireless driver". Cool. So I went ahead and installed 9.10 (dual boot with Vista), repeated above steps but found no "Broadcom STA wireless driver" option, in fact no proprietary drivers. So I still cannot connect to the Internet, and I don't know where to go from here. (Note: I installed 9.10 side by side with Vista: good? bad?)
So I wanted to replace my password prompt with this:it says to write it over the system files in ubuntu, under usr/share/gnome-screensaverbut i cant do that, as it says permissions are denied...
while installing ubuntu i made two partitions and set two load points. //home/but in ubuntu there is only one partition shown(filesystem).. what is going on?
I'm about to install Ubuntu on two 250-gigabyte hard drives in a RAID 1 array, but I'm confused about how to partition my hard drives. How much space should I give to each partition? How many partitions should I create and where should I mount them? (I should mention that Ubuntu will be the only OS on this array.)
I am trying to install Ubuntu server edition on an old HP XT963 that recently came into my possession. I mainly just wanted to use it as a home file server and print server. I have been running ubuntu desktop on my laptop for a little under a year, but this is my first go at the server edition.
While ubuntu was installing it said "network autoconfiguration failed," I hit continue, thinking I could figure out how to configure it later. After lots of googling I still haven't figured out what exactly is wrong.
Code: auto lo iface lo inet loopack after googling around I made it look like:
[Code]...
I would like to provide more information such as ifconfig and any other commands but I'm not exactly sure how I would do that without being able to copy/paste. I guess I would have the command dump the output to a file, but I'm not familiar with the -options this being my first time CLI-only.
I installed Ubuntu 9.10 and tomcat 6 java servlet container. I am trying to run the tomcat server on port 80, so I edited tomcat's configuration file (server.xml) and changed the default port from "8080" to "80". I launched tomcat server, went to my browser and entered:[url], but it says can not find server/location. Then I edit the server.xml and revert back to port "8080" and then enter: [url] and everything works fine. So my guess is some other service is taking up port 80, but I would think not, since I just installed Ubuntu and made sure apache isn't installed or running.
So I went to "System" --> "Administration", then choose "Network Tools". I then executed Netstat and did not see anything taking up port 80, but I do see port 8080 taken (assuming it is the tomcat server). Then I also did a Port Scan and entered my IP number. Again, I don't see port 80 taken, but do see 8080 being used.
I had a winxp laptop computer behind home wireless and was running tomcat 6 server fine with it, but it over-heated and died recently. So I got a used laptop and just installed Ubuntu 9.10. I have not changed my wireless router settings. It is the same as before. So I have ruled out my home's hardware/network equipment.
So here now I sit, wondering what is up?
For security reasons, is port 80 initially blocked by Ubuntu for some reason? Is there something I have to do beforehand to free up port 80?
Alright guys, I'm out of ideas... I have a system here with three harddiscs, the first is a 500GB disc which is supposed to contain Windows 7, the second is a 250GB disc for Ubuntu 10.04 and the third is a 1TB drive which contains all my music, movies and stuff like that.
Now I installed Windows 7 first, then Ubuntu 10.04 onto the other disc.The thing is that the Ubuntu-Installer gave me the option of installing them side by side by shrinking the Windows Disc, which I don't want it to because I hate to clutter up ONE drive with more than one OS, So,after installing and rebooting into Ubuntu, I went to see if I could still start Windows 7, which I now can't.
Is there a way to have Windows 7 and Ubuntu 10.04 playing nicely together WITHOUT swapping the SATA ports or something like that?don't ask why i'm giving Ubuntu the smaller drive... I'm still a gamer, and my games need a lot of space.I just want to make a switch to Ubuntu for the times where I'm not playing any kind of Games.
By the way: Both Operating Systems where installed in 64-bit flavour.
A few days ago I ordered a UMTS USB-stick from Fonic and I received a Huawei model E1550. Win and Mac install files are on the stick, but nothing for Linux. I found for the USB Modeswitch "drivers" at www.draisberghof.de/usb_modeswitsch/ (nothing about the program source on the producers web page - strange), but the install gave me a lot of errors, and after a while, I decide to find another "approach". I think you might find this useful. This is my approach for Ubuntu 10.4 LTS. Open your terminal and type:
Save and close. To setup you mobile broadband connection go to System / Preferences / Network Connections, (or type in terminal ~$ nm-connection-editor) select the Mobile Broadband Tab, Add new and follow the assistent. The only changes I made, are the country of the provider, and the provider. (In my case Germany, Fonic) If you have to type in the settings yourself for Fonic, visit [URL] If the device is plugged, it will connect after a few seconds.
I'm wondering how I can enable LDAP support for my Ubuntu 10.04 LTS server running Apache 2 and PHP 5.3.2? What I'm trying to do is allow users on my existing company's LDAP system to login to my Elgg site automatically (and possibly have their details filled automatically).
I am trying to install Fedora alongside Ubuntu but have run into a bit of a snag. I have the ISO burned to a disc, but it will not load on startup and doesn't have a prompt when the cd loads normally. I have files on the cd, but Ubuntu cannot read them.
Would it be possible for a video chat service to work between computers running Ubuntu 10.04/10.10 on the same LAN, but necessarily with an internet connection? Computer #1 wants to video chat with Computer #2 in the next room, part of the same network, but this network has no access to outside internet...
I just bought a new Windows 7 machine and want to install Ubuntu 10.10 for a dual boot environment.There's a lot of info describing how to do this, but it all describes re-partioning the Windows drive, burning Ubuntu on a CD, inserting that CD, etc. I had a dual-boot Windows and Ubuntu machine that just died on me. Windows was on one hard drive and Ubuntu - along with my entire software development environment - was on the other. As far as I know both drives are fine.
When my new (Windows) machine gets here I want to open it up and stick in the Ubuntu hard drive from my old machine... but then I'm not sure what to do. I'd really like to be able to boot to that hard drive (or the Windows one), just like I did before. It seems that this should be simpler than installing a fresh Ubuntu from a special CD, after all, everything is already expanded and working on the hard drive. Can someone give me some pointers that will help me solve this problem?
