Google colab is showing busy - jupyter-notebook

I ran a training process on google colab yesterday. Now the google colab is showing busy, even after restarting runtime and interrupting execution. I want to stop the current execution. Please help!

Selecting 'restart runtime' from the runtime menu should suffice.
If for some reason that doesn't work, you can drop your current backend and start fresh with a new one by selecting the command 'Reset all runtimes...' from the Runtime menu.

It means that your code is running. You don't need to get panicked. Just wait for your code to complete the execution. Your kernel will become ready to use again after that.
As per your scenario, if it's still busy even after complete execution, you can do as in the above answer (Reset session)

Same problem: stuck with 'busy' and 'reconnecting' status.
'restart runtime' didn't work.
Change GPU/CPU didn't work.
Runtime -> Manage Sessions -> Terminate worked.

When it happens with me I go to google webpage, disconnect my accounts and log in again. Then the colab comes back to work.

After performing: Runtime -> Manage Sessions -> Terminate worked.
I pressed reconnect on the top right and it was worked.

I experienced the same issue.
For me, I reset all runtimes, force quit chrome using the task manager and restarted my computer. Some of these steps probably weren't necessary, but the combination of all of them solved the issue for me.

Expo: "Something went wrong" immediately on start

I have used Expo a few times successfully before, but for a few days now, I am unable to get into the Expo App. Whenever I open it, I see the Expo icon for a few seconds up to even minutes, and then it redirects me to the blue "Something went wrong" screen, as if I had tried to open an app.
But I didn't! It doesn't even let me scan a QR code, it just always shows this error. If I click the back button in the app, it simply terminates. I have ensured that it is the latest version and already reinstalled it once.
It seems like it somehow had locked itself onto an old, now non-existant server, and kept at it after reinstalling the app. Here is how I solved the problem:
In the metro bundler, choose connection type "Tunnel" and copy and send the URL to your phone. If you then click on it on your phone, it should redirect to the expo app. After that it got unstuck and I could finally use it normally with the QR code again!
The tools sometimes do get locked into this state.
Close and restart all components (Expo cli, browser tabs and clients) making sure to:
Kill any stray processes on the server (you need to check Activity Monitor / Process Explorer or similar depending on your platform)
Force quit all client devices and simulators using the correct method for each platform. To verify that the client process has actually been killed, check that the app splash screen is displayed for a short while when invoking it.
Clear the Expo cache when starting again: $ expo start --clear
I ran into the same issue. Solved it by going to the left sidebar in the Metro Bundler and sending a link via email!
I've tried many of the solutions and only one worked for me (which i found trying random things). I already had 'allow display over other apps' turned on (Android/OnePlus 6t) and didn't think it had anything to do with that. But I tried this...
Close the Expo app, go the the app settings and turn off 'allow display over other apps', open the expo app and [when prompted] turn on 'allow display over other apps' again.
That seems to work in my case - at least until the next time.

What's the modern way to solve Plone deadlock issues?

I currently have a Plone 4.3.8 site where editing a portlet causes a deadlock.
I'm trying to find tools to fix this, but most deadlock tools don't work & I'm not getting good information (IMO) from those that at least run.
I've tried:
z3c.deadlockdebugger => can't get to a stacktrace
ZopeHealthWatcher => can't see the results on command line (or webpage)
Products.LongRequestLogger => perhaps the best so far, gives me some log output - but it's stack traces focus on Diazo code, but the problem still occurs when Diazo isn't in scope (running against 127.0.0.1)
gdb attach - just landed me in C code
winpdb => it can't attach to running processes in the same way that gdb can (only to processes started with the intention of attachment by winpdb)
Products.signalstack (OR Products.signalstacklogger) => USR1 signal just shuts down a zope process!
Note: z3c.deadlockdebugger (and things that depend on it) needs checked out source code to drop the threadframe dependency.
My situation seems to be linked to product upgrades - probably one or both of either plone.app.contenttypes or plone.app.multilingual, an empty site doesn't have this issue, but I obviously I need my site data!
What should I do to progress this?
EDIT:
I believe Maurits answer to be the most correct one, but it didn't work in my case. What I ended up doing was using pdb to track down the point at which the code was hanging (in plone.app.debugtoolbar as it happens)
You say that using the USR1 signal shuts down Zope when using Products.signalstack. But no special packages should be necessary, so I wonder if adding signalstack has this side effect of shutting down Zope.
At least for me, a few weeks ago, this worked fine on a Plone 4.3.something site:
kill -USR1 $(cat var/zeoclient.pid)
Although the #maurits answer is right (and the simplest ones) sometimes I had issues seeing the traceback resulting from the kill command: sometimes is found on the event log, sometimes on the shell.
I prefer the integration of the buildout with haufe.requestmonitoring, configuring also the monitor long running requests feature.
You will see the deadlocked traceback in your event log and also you activate a tool for monitoring low performance on your Plone.

VS2015 Design view unresponsive issue

I am able to work in the Source view with no problems. However, as soon as I click Design the source freezes and hangs. The same thing happens when I switch to Split as well. I cannot find much documentation/support for this issue and wondered if anyone else ran into this as well or has a potential fix?
Firstly please make sure you have selected the project/solution you are working on ,on the left bar (esp. if working with multiple projects.)
When that is done, clean and rebuild your solution. When this is done , try again.
If all fails, restart your machine and IIS (in that order) and try again.

Meteor.js - randomly everything is 'undefined' -- why?

So I'm working on my Meteor project and all of a sudden everything stops working and my console reports that everything is 'undefined'. See screenshot. Why does this happen? Usually things will just randomly start working again after I reboot my machine or go get lunch.
This can happen if you have a hot code reload during when the page is loading from a previous hot code reload.
Your browser will eventually reconnect to the server, reconnect & refresh the page. In the case above it looks the the bit of Js that connects to the server doesn't get loaded to begin with (the DDP bit) so it doesn't behave as normal. If it reconnects it can fix it self by refreshing.
It's very hard to tell what exactly is causing it from the information you've given. I'd look at custom packages that replace core packages or some kind of of package you have that runs early on in your code that would stop the normal loading of a project.
If you're using meteor on windows there are a couple of bugs that do this too. I'm not sure how to get past those besides doing Ctrl+C to stop and then using meteor to start the project again.

How do I debug server side code in Aptana Jaxer?

I'm trying to debug some server-side JavaScript code running in Aptana Jaxer and I'm not having any success. I haven't even been able to find any tutorials or posts about this issue. Does anyone know if it's possible and if so, what am I missing?
You can set you Jaxer.Config.DEV_MODE = true; to get some error information in your browser.
Also use the Jaxer.Log to debug.
Hope this helps a bit.
Jaxer and Aptana Studio do not yet have the ability to debug remote scripts from the client side. That is, you can't single-step into a callback and have your code window show you the first line of code in the remote method. This is on their wishlist, of course, but it'd be pretty tricky to do well.
Personally, I use logging. Jaxer has strong facilities for this, in Jaxer.Log.*.
A lot of people sneer at "printf() debugging", but the fact is, it works, and it's often less trouble to set up than an interactive debugger, especially for server applications and remote method invocation. You just sprinkle logging messages wherever you want to know the state of the system at that point, then make your app try to do the thing that's failing. Study the logs, rinse, repeat.
tail -f /opt/AptanaJaxer/logs/jaxer.log
