Jupyter webpages not displaying properly - ipython

Screen shot here.
With Cntrl-Shift-I
No matter how I install Jupyter(aka IPython) I get a dud webpage. It does not display tabs or menus as expected.
The screen shot above is from a 64bit Windows Anaconda install. It was a default install. Install finished. No changes to configuration. First action after install was select IPython menu item in start menu.
Now, trust me, I have tried everything. I have tried installing IPython from pip over top my python2.7 installation, anaconda etc. No matter how I install it ends up with the same problem. I even tried 32bit installs etc.
It doesn't appear to be the browser as both IE and Chrome see the same mangled display.
It is almost like the css files are not being picked up or are not there at all.
I opted to allow the installation of the Anaconda to update my environment variables etc. so the dang blasted thing should be finding where it has put itself.
What is the likely cause? What is the fix please?

I did have a very similar issue on Windows recently. Some program has overwritten your mime type associations. For me it was Inkscape killing SVG by setting the mime type to application/svg.
Try this on terminal:
import mimetypes
mimetypes.guess('file.css')
You should get text/css. If you get application/css this is most likely your problem. My solution: Change back the mime type association. Start regedit and search for application/css in HKEY_CLASSES_ROOT. Replace it with text/css.
Please refer to this https://github.com/ipython/ipython/issues/7024 for further reference.

Can't install neovim in windows

I want to have neovim. I installed it with choco install neovim in the PowerShell (admin). Then I followed a lot of tutorials, like the one of theprimeagen, but I can't get pass the first steps. Maybe is because I don't have Linux, as everybody does, but I don't think is that.
I created a folder like so: C:/users/myusername/.config/nvim. Then, in this folder I type nvim . to open the Explorer of neovim and start creating the .lua files. The problem is that I always get a stupid .nvimlog every time I enter neovim, I think is the reason why I can't install plugins correctly or remap some keys.
In the .nvimlog every time I enter neovim appears a new line that says:
ERR 2023-02-12T12:55:04.800 nvim.15716.0 terminfo_start 374: uv_tty_set_mode failed: invalid argument. And I swear I followed every tutorial in the exact way, and even without creating any file the .nvimlog is always there.
In windows, the default config directory is ~/AppData/Local, based on their official documentation. I don't know if there is a way to change that, but that is how i configured it.
To find out where your config directory is you can also use :echo stdpath('config').

VSCode on Linux Mint, integrated terminal not able to type anything

Hi I'm running Linux Mint 19 and I have just installed vscode using the snapd package manager. I've not used vscode on linux before as my usual editor is emacs. However, on a fresh new install of vscode, the integrated terminal does not work, there is just a non blinking cursor in the top left of the screen, but no prompt and no keyboard strokes are registering. This appears to be a common problem as there are a lot of posts about it if googled, but they are all for Windows versions and none of the solutions that I'm able to try do anything. I've tried to open a new terminal window, but the same thing happens I just get two terminal windows that I now cannot use. I've also tried checking the box that says Code-runner: Run In Terminal, but that does nothing either. What can I do to get this to work please, I looks to me like it is just not connected to either a bash or Zsh(which I normally use). Any help on this would be appreciated.
Instead of starting vscode with its default shell script (usually located on /usr/share/code/bin/code), the integrated terminal only works for me when starting it directly from the compiled binary (typically found on /usr/share/code/code, which is the same as the launcher created by the installer:
/usr/share/code/code --no-sandbox --unity-launch %F
While I searched for a solution in the past I've also noticed that lots of folks solved similar problems just by adding --disable-gpu flag, so might be worth checking out as well.

zsh autocompletion appears to only work with built in commands

I'm new to zsh, just switched over from fish. I'm trying to get autocomplete working so it displays argument/flag options for commands upon pressing tab.
Currently this works, but it only appears to work for built in commands. For example, it works for ls, grep, git, etc. but does not work for programs I have added myself. For example, fd-find, exa, and nvm all do not work.
For nvm, I have enabled the nvm plugin using Oh My Zsh. I know the plugin is working in general, because nvm itself is working (and it wasn't before enabling the plugin).
For fd-find, I see the auto-completion file in /usr/share/zsh/vendor-completions/_fd
For exa, I manually downloaded and placed the autocompletion file in /usr/local/share/zsh/site-functions/_exa as instructed by the site.
All 3 of these programs do not show me the typical arguments/flags autocomplete menu the way built in commands do. I'm not sure what is wrong.
I echoed the fpath environment variable to make sure /usr/local/share/zsh/site-functions was in there. It is, along with /usr/local/share/zsh/site-functions/
When I run which nvm, I get:
_nvm () {
# undefined
builtin autoload -XUz
}
Which is actually what I get for all of _nvm, _exa, _fd.
Not sure what else to try.
Any suggestions for how to get autocomplete working properly?
Other info: I'm on a System76 Darter Pro laptop running Pop!_OS.
I found a fix that worked for me. After searching through zsh issues related to autocomplete on github, this solution worked for me. Credit was given to the original source of the solution on stackexchange.
The solution was simply to remove all zcompdump files:
rm ~/.zcompdump*
After running the above command, autocomplete works and expands out the possible flags/arguments for non-builtin programs!

eclipse - swt - using windowbuilder in xfce env

I have some problems with eclipse indigo x64 Linux; The problem is using windowbuilder (the SWT); I tried using gwt or swing but they both cause either windowbuilder freeze or even eclipse crash...
The alike issue it seems I found related info in official eclipse indigo offline Help which says :
How can I prevent the preview window from flashing under Linux using Metacity
In order to create the graphics that you see in the design view,
WindowBuilder Pro creates an off screen window containing the various
widgets and they takes a screen snapshot of them. This works very well
under Windows, OSX and some versions of Linux. Recent versions of the
Metacity window manager (more recent than 2.1.4), however, have been
modified/"fixed" to disallow windows to be opened off screen. This
forces the preview window to appear on screen leading to an annoying
flashing effect any time you make a change. The solution is to disable
the Metacity "fully_onscreen" constraint by patching the Metacity
source code and rebuilding and installing the patched version into
your system.
Here are the steps to follow:
Download the Metacity source code from ftp://ftp.gnome.org/pub/gnome/sources/metacity/
Unpack the source code tarball into any temporary directory.
Chdir into this directory (with the unpacked code).
Find window.c file and open it with your favourite texteditor.
Find a line with "window->require_fully_onscreen = TRUE;"
Replace it with "window->require_fully_onscreen = FALSE;"
Save the changes and close the editor.
Open a terminal and chdir into the directory with the source code (nice if you have already done this)
Run "./configure".
Run "make all".
Make sure that steps 9 & 10 completed without errors.
Become root (or execute the next command via "sudo" depending on the Linux you are running)
Run "make install" (or "sudo make install").
Save your work and close any application you are working with.
End your session (or press Ctrl-Alt-Delete to restart the x-server) and log in again.
You are done!
well seems like I have the snapshot really but, as I can get it, the snapshot doesn't want to dispose or similar so I have either resize the whole eclipse or press F5 to refresh (which works not at once);
I am not sure how to fix the issue in case I have xfce+adwaita installed? I don't have metacity installed; Seems like xfce works with gtk instead of metacity (correct me if I am wrong);
So my question is... how to fix the "window flashing or freezing" if I have :
xfce4
adwaita-dark theme
linux arch x64ce
Thanks
Try to install install libswt-gtk-3-jni and libswt-gtk-3-java.

VSCode ran once on install, won't run or install again

I'm running this on Windows 7 SP1 with most (if not all) current patches. I have administrative permissions on this machine.
The first time I ran VSCodeSetup.exe, it ran the installer for several minutes then launched the actual application.
I got called into a surprise meeting, so I closed it thinking I'd look at it again later.
However, when I returned to my computer and tried to launch it, I found no evidence that it was actually installed... no desktop icon, no entry in the start menu, no Explorer integration...
I tried running VSCodeSetup.exe again, but all it does it show the installer screen for a split second, which then vanishes.
Since then, I've tried the suggestions outlined in VSCode Installation Failed - Failed to extract installer to install the application, even going so far as to run Update.exe --uninstall followed by running VSCodeSetup.exe again, but nothing has worked.
I even tried disabling my antivirus software and running the installer again, to no avail.
Does anyone know what I can do to get VSCode working again?
According to the comments and answers to Install VSCode in a specific folder, Visual Studio Code installs itself to %LOCALAPPDATA%\Code on Windows.
While I'm not sure why it didn't register itself with Explorer, I can at least create a shortcut to %LOCALAPPDATA%\Code\bin\code.cmd (with icon %LOCALAPPDATA%\Code\app.ico) to get it working again.
Or remove the directory entirely and run VSCodeSetup.exe to install it again, which still doesn't add Explorer integration... but this time at least the PATH now has code in it.
On windows VSCode is installed as Code.exe and its located in your
C:\Users\<windows-user>\AppData\Local\Code\app-<version-number>\Code.exe
or
C:\Users\John\AppData\Local\Code\app-0.5.0\Code.exe
