I'm trying to run two notebooks on Google Colab but could only connect one notebook at a time to the virtual machine. There's a pop-up message saying "Too many sessions. You have too many active sessions. Terminate an existing session to continue." when I click the "connect" button on the second notebook. Does anybody know why?

Edit: I'm using Google Chrome on Windows 10
Edit March 3, 2020: I ended up not using Colab that day, but I came back the next day and was able to run two Colab notebooks just fine. strange. I had this issue a couple of times since I posted this question, but the error disappeared the following day.
I am used to use it with 2 active sessions. I mean, it gives that error when I try to connect for the third notebook. Today, however, I could only connect 1 notebook at a time. It does not permit the second connection. Therefore, the limit changes time to time.
I have the same problem and I found my solution in this issue. I change the Runtime Shape to Standard in the 2nd notebook, it worked for me.
Try this:
Go to Menu "Runtime" > "Manage Sessions", you should see a list of active sessions. Terminate those you don't need. Although you think you are opening only 2 notebooks, some previous sessions may still linger around if you just close the browser tab.
Note: However, when I hit the problem today, I did the above to check, and I have only 1 other session. Usually, I am able to run up to 3 separate sessions. I am not sure if google is dynamically adjusting this based on overall demand. I also suspect ever since they introduce the Pro, priorities may be given to subscribers.
Im not sure but may be collab provides services to a account one at a time..

All my datasheets, tables, and ALL items inside BQ are un EU. When I try to do a View->to->Table 15 min scheduled query I get an error regarding my location, which is incorrect, because all, source and destiny are both on EU...
Anyone knows why?
There is a transient known issue matching your situation, GCP support team needs more time for troubleshooting. There may be a potential issue in the UI. I would ask you to try the following steps:
Firstly, try to make the same operation in Chrome's incognito mode.
Another possible workaround is trying to follow this official guide using a different approach than the UI (CLI for instance).
I hope it helps.
I have 2 monitors at work and 2 monitors at home.
When I log into work from home using mstsc /span, my work desktop appears correctly spread across my 2 home monitors.
Then I want to open another RDP session on my work machine. When I maximise that window, it now fills both of my home monitors. How can I make it just fill the monitor it is on - like it would if I was at work and NOT using mstsc /span?
The solution is to edit the file "default.rdp" created in your Documents forder.. You need to add a setting for "selectedmonitors:s:x,y,z,*".
If you want to know which number is your monitor, execute "mstsc /l" in ms-doc command.

Scott Hanselman also answered inside a comment with his own blog. his solution is very detailed:
https://www.hanselman.com/blog/HowToRemoteDesktopFullscreenRDPWithJustSOMEOfYourMultipleMonitors.aspx
This is an old question but I'll suggest an answer now anyway in case someone lands up here.
It seems to me that to solve this problem there is no need for selectedmonitors in the RDP file. Instead of using /span to connect to work you should be using /multimon.
/span creates one big "screen" across your two home monitors. So when you go "fullscreen" in your work session it goes across them.
/multimon makes your work computer aware of your two-monitor setup. When you maximise a window or go full-screen it will do so in the way you'd expect.
As I have found recently, selectedmonitors could be useful if your primary monitor at home is not the one which you want to consider the primary in your work session.
I was recently working in a notebook on Google Colab and my computer ran out of battery and died. All the progress I had made was not saved anywhere!
I'm very used to having jupyter notebooks, which saves my files pretty much every time I execute a cell.
Is there a way to have an equivalent feature in Google Colab?
Autosave is already implemented in Google Colab, but there is a certain delay between the moment you execute a cell and when the save occurs.
You can try this yourself by going into File>Revision History, executing a cell, and waiting for the list to refresh.
That being said, I have also experienced loss of data in the past, which I can't explain. It might be a glitch.
As a good practice, I try to save every time I remember.
Good luck.
Autosave every 60 seconds by running this "magic command" into a new code cell :
%autosave 60
Colab will confirm it when you run the cell with printing : "Autosave changes every 60 seconds"
To display the list of all magic commands you can use the command :
%lsmagic
Additionally, you can call the Quick Reference Guide, describing all the magic commands and what they do using the command :
%quickref
Enjoy!
Situation and Problem: We are working with Citrix + Windows Terminal Server 2012 R2 and we are experiencing that a single Internet Explorer (Version 11.0.96) process can use up to 60-80% of CPU-Power. Since there are 15 user working on one Server any given time, one or two users can disturb all the others by using all the available CPU-Power.
First (insufficient) Solution: To overcome this Problem, We changed the Internet Explorer shortcut from the users startmenue (tile-design menue): We are starting the Internet Explorer just with three cores (out of 6 core) with this command:
start /Affinity 7 iexplorer.exe
Problem: If the users start the Internet Explorer from a link (out of word, Outlook or wherever), the Internet Explorer is starting again with all six cores.
Question: Is there a way to start the iexplorer.exe process (Independent from the starting point) always with less cores, or is it possible to limit the CPU-usage for a specific process..?
That's just two possibilities I'm thinking about, if you have other solutions in mind, feel free :)
Thanks and greetings Kevin
Many reasons can cause this issue, Like due to issue in a update, due to homepage, due to add on.
So you need to check one by one that what thing cause this issue.
You can try steps below and check whether CPU consumption reduced or not.
(1) On the General Tab click Tabs button and unchecked the option "Show Previews for individual tabs in the task bar".
(2) Go to the "Advanced" tab in "Internet Options" and checked "Use software rendering instead of GPU rendering".
(3) Temporarily disable all the add on and turn on them one by one and check the consumed memory every time. If if you find any add on consume high CPU then remove it from IE.
(4) Try to check whether issue caused by a faulty update.
You can also try to refer MSDN article below and if you are using that specific update then try to apply the hot fix may solve your issue.
Internet Explorer 11 consumes high memory and CPU cycles after you install update MS15-106
I recently upgraded from 2005 to 2012 (about 10 months). When I first started using SSMS2012 it worked great was able to open multiple windows in a particular database. For about that last 2-3 months SSMS hangs when I try to open more than 1 query window or open a file. It is random but happens a majority of the time. I have been able to interrupt the hang a few times. When I interrupt it I get the login screen and it sits there trying to log in apparently unsuccessfully. If I cancel the login and try it again with the same entries it connects just fine and things are great, but I have to do this for every window and I cannot often break into that screen before it stops responding.
I have searched extensively and have not found an answer to this problem. It only appears to be happening to a particular instance. The instance does not show any signs of issues, has been rebooted and configuration checked for inconsistencies, etc. I am at a loss. If anyone has experienced this and has been able to resolve it I would appreciate a response.
Again this is a fresh install of 2012 standard with 2005 imported databases. All indications show that it is working fine. compatibility level for a majority of the databases are still 90, until I can clear them for 11 with the software they house. I have a test environment with the restored versions on a different server and no issues result from that instance - I can open up multiples without incident. My belief is it is something with that particular instance, but I am not sure where else to look.
Thank you in advance.
