I have installed (and re-installed) Octave 3 times on Windows 8, and I still can't get it right. The first and most obvious problem is that the prompt is missing; the screen only shows the flashing underscore that follows the prompt. This is not a major problem since the system properly responds to commands.
The major problem is that Octave crashes whenever it encounters a syntax error, instead of politely giving a diagnostic. This makes for extremely tedious software development.
Is there a way around this problem, or do we just have to wait for one side or the other to come up with an accommodation?
I encountered the same problem. I solved it by this:
create a shortcut to octave.exe, then right click->property-> change the "target" to something like:
C:\Program Files\Octave\Octave3.6.*_gcc*.*.*\bin\octave.exe -i --line-editing
Then it won't exit if u have syntax errors.
I don't understand the meaning of the parameters yet.
reference:

Type octave --help can check the meaning of parameters.
-i also --interactvie, to force Octave interactive behavior.
Maybe Octave run at non-interactive mode at default, that means prompt should not be shown and it should terminate immediately when encountered error when reading a file.
I don't know if this will solve your problem, or if this is too bloated of a solution for you, but I use Octave on Windows 7 through Cygwin without any problems.
If you can't get Octave to run on Windows 8, you may consider running Octave through Linux via computer virtualization technology (virtual computer). Two, off the top of my head that you could use are VirtualBox by Oracle or VMWare Player
Once you have it installed, you can go to any number of sites that have pre-built Linux images that you can download and then run inside of Windows 8.X. Do a Google search of for 'Virtualbox images' or as 'VMWare appliances'. You can then download and use that to run the lastest version of Octave. I hope that helps.
Cheers,

My first stack overflow question, here we go.
Last week the computer on which a prototype vision application written in C#/.net was running crashed due to an unreleated reason. this resulted in the need to fresh install windows (windows 10 IOT). after installing windows, halcon 20.11 progress and setting the licenses the application starts, but no output is shown on the smart window control, even tho this worked beforehand?
i have been trying to debug this problem for the last day, but have had no luck, what i have allready tried:
used the remote debugging toe verify that the image is captured and processed and "displayed".
checked the system logs for any warnings, there were none.
Tried one of the example programs the come with Halcon, which also does **not **work.
Ran the application on my development PC, which worked flawlessly as it always did.
Reinstalling Halcon.
does anyone have had any similar experiences and/or any clue how to solve this problem?
problem has been solved. in the end a reset of the bios settings to there default values did the trick. Don't know what they exact cooperative was, but at least it works once again.

I want to setup monodevelop on this machine. I followed the instructions and am able to run monodevelop and write code, however when I attempt to run it I get "Could not connect to the debugger". I tried various solutions suggesting changing environment variables to force monodevelop to use xterm and it did not work, however I'm not positive I did it correctly as the solution was meant for gnome and the modifications to the command for XFCE were not clear to me. At this point I'd be willing to get paid support, but I'm not even sure where I could find any for my use case. Does anyone have experience getting monodevelop to work on XFCE? If not what is the best environment for getting it going (ideally a way where I could remote in too). I'm very accustomed to the RDP workflow where I can actually troubleshoot on a development server and be very close to the real world environment to get things running, then check-in and deploy. I think there are a lot of platform differences with monodevelop so I really really really want to develop on Ubuntu (remotely).
I use manjaro linux and run applications from the terminal. Recently when I type idea (running I assume idea.sh, as this is what the top of the terminal says), and try to minimize and expand the idea window the terminal prints "Everything has changed". Is this something I should care about or is it just some random text?
everything has changed
It's a bug in the bundled JDK, should be already fixed in a later version: https://youtrack.jetbrains.com/issue/JRE-854
I use avrdude on osx to do development for an xmega256a3. It's wonderful, it lets me flash my target just fine. However, when I try to use it to program the usersig block, it doesn't work so well. I was initially excited by some early success with it, but found subsequent flashes weren't working.
Through testing, I determined that if my usersig file was for all 0's, it worked fine. But all FF's didn't work. Given what little I know about flash, these leads me to believe that I'm either missing an option or avrdude isn't doing a complete job for what it needs to do here.
The command I'm using is
avrdude -p atxmega256a3 -P usb -c avrispmkii -e -U usersig:w:mySig.hex
Using AVR Studio 4 on a Windows box, I am able to program any of these files to the usersig flash block.
My question boils down to is this possible? if so what option/incantation am I missing? Or am I out of luck for programming usersig for this processor with avrdude?
(I'm using version 5.11.1 from the CrossPack guys)
It turns out that old versions of avrdude indeed did not support this. It requires a page erase of usersig, and that was not supported until version 6, which is due out soon. I've tested with svn builds of it, and with a two line patch submitted to day, it does the job.
I am having problems getting the GTK designer to work with MonoDevelop. I tried 2.4 on Arch Linux and it gave this problem. Then I tried 2.2 on OpenBSD and it gives the exact same problem. Both machines are 64bit.
Instead of having a window to drag things on I just have a blank square:

The tutorials I've seen look similar to this though:
alt text http://monodevelop.com/#api/deki/files/142/=Stetic_Tutorial_06.jpg?size=bestfit&width=700&height=425
So what gives? With my blank square I can't drag anything onto it, not a VBox or other container even. It will not react to anything.
Am I missing some sort of GTK# configuration or what? I find it highly improbable that both OSs' packages I tried are broken. Also, I've attached a (huge) bounty to this because this is a pretty big issue for me.

Update
Ok, so I've finally gotten a bit closer to solving the mystery. I use Fluxbox as my window manager usually. Well I tried using both KDE and Gnome-Session and both of them cause MonoDevelop to work properly(though still missing the window border, you could at least drag components onto it). Now my question is what makes Fluxbox not work for it?
I have the same problem in openSUSE 11.3 x64 KDE using Mono JIT compiler version 2.6.7 (tarball Wed Jul 14 18:00:23 UTC 2010) downloaded from here
type -a monodevelop returns:
monodevelop is /usr/bin/monodevelop
monodevelop is /usr/bin/X11/monodevelop
Running monodevelop from terminal gives the following output
1)

This can be solved by adding an environment variable in your .bashrc file from your home directory.
export MOZILLA_FIVE_HOME='/path/to/libgtkembedmoz.so/directory/'
To find if that library exists on your systems use:
sudo find / -name libgtkembedmoz.so

(from this bug report this library is contain in the Mozilla's XUL Runner package, but in newer versions I don't know if it's still there, I had to use libgtkembedmoz.so provided by Slickedit which was installed in /opt/slickedit/bin/mozilla/)

I get the exact same error using Monodevelop 2.4, and I think this could be either from a broken GTK# installation or from a bug in Monodevelop,
Your result is the same as mine, see here. I suggest compiling MonoDevelop from Github and/or using a newer version of gtk-sharp/gdk-sharp
This part

If this does not resolve the problem submitting a bug report is the next option. Although this is somehow strange, since I managed to complete the same tutorial using Kubuntu 10.04 LTS 64 bit a few weeks ago.
Uh, that is the designer. If the toolbox didn't show up, go to View->Pads->Toolbox to bring it up.
Note that this Gtk, you can't just drop a button or textbox on the design surface. You have to drop a container control first, and then can place buttons and such inside the container.
set global gtk theme to default
check all bindings depends
try start monodevelop from console and post output on pastebin
"Now my question is what makes Fluxbox not work for it? " remember the GTK protect was made for GNOME project, all the libraries are made to work on that Desktop. so need to see all the dependencies to run it property
