MATLab Drive Connector fails on startup - matlab

Hi,
I have a problem on my Mac OS X 10.11.5 Beta (15F31a), with MATLab R2016a (9.0.0.341360). When I install the MATLab Drive Connector from the website as matlabdrive.mlpkginstall or from the add-ons menu in MATLab itself, it works absolutely fine; it synchronises my files and displays its logo in the menu bar top-right, through which I can access its menu/settings/etc.
However, upon the second start-up of my computer; MATLab Drive Connector is no longer usable. When I open it; an empty menu space is created in my menu items; and when clicking on that space, it's marked as selected; but nothing else happens, nor are my files synchronised. When I have selected the MATLab Drive Connector to start at startup right after its installation, the empty space is immediately created, with the same effects. When MATLab Drive Connector is forcibly stopped via Activity Monitor; the empty space will disappear. I have attached a screen recording [1] of this issue.
The only temporary fix was to deinstall & reinstall the MATLab Drive Connector, after which it worked again,
EDIT:
however since two days, even when attempting to de/re-install, I get the error "The specified key is not present in the current container", as shown in the attached screenshot [2] preventing me from doing anything to fix this issue.
I hope you can provide me with a solution, as the MATLab Drive Connector is very important to me, and I presume this problem also occurs to other users :]
Kind regards,
Isaiah van Hunen

If you take a look at the ~/Library/Application Support/com.mathworks.matlabconnector folder on your computer it should contain a folder with the same name as your computer. This folder should contain three folders called locks, logs and services.
The com.mathworks.matlabconnector folder may also contain a second folder with a longer name – probably your computer’s hostname including the domain you are connected to - something like macbook-wifi.example.com - if this folder exists it probably contains a single folder called "start".
If this second folder exists, then I have a solution for you to try:
Move the "start" folder from the second folder into the first folder. This folder should now have four folders: locks, logs, services and start.
Delete the second folder that should now be empty.
Start MATLAB Drive Connector
Now when MATLAB Drive Connector is started it should now find the correct folder and start correctly.

I had a similar issue under Win 10. Typically Connector can be started by clicking its icon in the MATLAB folder in the Start Menu. This however requires a confirmation of User Account Control (UAC). So one needs to eliminate that, so that it doesn't cause an issue on start-up.
Find the folder where the Connector exe is located. For me it was at: C:\ProgramData\MATLAB\SupportPackages\R2016b\bin\win64\MATLABConnector.exe (note that ProgramData is a hidden folder, so make sure you enable hidden files under View in the C: folder).
Next find the Windows start-up programs folder. Hit the "Windows key + R" keyboard combination, then type "shell:startup". The folder should already contain a Connector icon, remove that, or cut & paste it to the Desktop. That icon also required UAC confirmation, so it's no good, we need an icon that doesn't require it.
Follow this tutorial to create another shortcut icon (without UAC) to the MATLABConnector.exe program: http://lifehacker.com/how-to-eliminate-uac-prompts-for-specific-applications-493128966
Once you have your new icon, cut & paste it into the Windows start-up folder you located in step 2.
Exit Connector by right-clicking it in the Taskbar. Then double click the new icon created in steps 3-4. and Connector should start again with no UAC verification step.
Restart your computer, and Connector should start automatically with no problems.

VS Code move Cache location in Windows

I am trying to use models from Hugging Face, but VS code always downloads them into my very limited C: drive; C:\Users\<user>\.cache.
How can I force it to cache to a different drive?
Things I've tried:
Googling: only seen threads for Linux, whose commands do not transfer over. Could not find clear equivalent commands for Windows.
Running a new instance from terminal code --user-data-dir E:/.cache
Fully un-installing VS Code, downloading a portable version, and making a data folder (following these instructions)
All of them still result in caching to C:\Users\<user>\.cache.
From some further research, it appears this is currently not possible.
However, I've found that symlinks is a great temporary workaround. In short,
Create a folder on a drive/partition with an abundance of space, i.e. E:\TempCache
Close any instances of VS Code, if any.
Navigate to C:\Users\<username>\.cache. If there's anything in it, cut them over to E:\TempCache, and delete the whole .cache folder.
Open cmd with admin rights, and enter mklink /J "C:\Users\<name>\.cache" "E:\TempCache". This will re-create an empty .cache folder.
Next time VS Code is ran, it will automatically detect and use the .cache folder on the C drive like nothing changed.

How can I change VS Code Remote Server's default download folder?

I often download file from vscode remote server, but how could I change default download folder? It always opens a specific folder I don't want to download into.
I don't know about configuring the detault download directory, but there was an issue created and resolved to get VS Code to Remember target directory when downloading files #140358, which was implemented in commit ca936dc.
bpasero (one of the VS Code maintainers) commented to close that issue as resolved:
For the "Download" command we now remember the path where to download and restore that. This information is stored globally (i.e. applies to all windows) but will not roam via settings sync, because paths are typically machine local.
Previously we did a questionable computation of a default path that typically always ended up in the user home directory, which imho does not make a lot of sense for the download operation.
Verification:
connect desktop to any remote
right click from the explorer "Download"
pick a destination
repeat and verify the destination restores even across restarts

Restore or access workspaces from MySQL Workbench

Using MySQL Workbench 6.3.8 build 1228 CE (64-bit), on Windows 10 Pro, version 1803, build 17134.112.
I want to restore my old workspaces in MySQL Workbench. If that is not possible, I will be happy with just being able to access them as text files.
I guess my laptop had an unusual power-off or reset last night. Normally I put it in Sleep mode, but when I opened it this morning it had reset itself: all applications had quit.
I re-opened Workbench, and got this error message:
saying that my workspaces could not be opened.
I can't get the full text of the error message, so I don't know exactly where Workbench is looking, but using Windows Explorer I could navigate to:
C:\Users\JamesBarton\AppData\Roaming\MySQL\Workbench\sql_workspaces
which looks right to me, and contains .workspace and .autosave directories.
I've backed up the Workbench\ directory, and then tried just removing the .autosave directories, to force the use of the .workspace directories, but when I did that, Workbench still just opened one empty tab. The first .workspace directory contains 95 files, including 45 .scratch files totalling 107kb.
Is it possible to check exactly where MySQL Workbench is looking for workspaces?
Can I force it to open a workspace directly, or at least show me why it can't open a workspace? If that is not possible, can I somehow extract the SQL from the .scratch files? Thanks.
Should be easy to recover the sql from the scratch files which are just plain text files. The sql code is not encrypted. Also you can look in the Workbench log file (see Help menu) to see if there's an error message or similar for a specific file. Could be there's some file corruption. Running the file system checker on that disk also might help.
PS: in Windows you can use the clipboard in system dialogs like this one. Just press Ctrl+C while the dialog has the focus to copy the entire text, including the button captions, to the clipboard. That will hopefully give you the full error message.
Even though my desktop has crashed several times in the past 3 years (either power-related or system) this last time was the first time MySQL Workbench had issues with a workspace (apparently the 2 I had open at the time?). When I investigated why I discovered that all the .info and .scratch files in those workspaces were written with only NUL characters so no easy recovery of my tabs is possible. Grrr.
I will have to recover everything from scratch (haha) by going through the sql_history and possibly log folders and copy/paste as necessary back into the GUI.

Eclipse says: “Workspace in use or cannot be created, chose a different one.” How do I unlock a workspace?

When I start, Eclipse says "Workspace Cannot Be Locked"
"Could not launch the product because the associated workspace is currently in use by another Eclipse application." or “Workspace in use or cannot be created, chose a different one.”
But I know it isn't.
How do I "unlock" it?
Just delete the .lock file in the .metadata directory in your eclipse workspace directory.
Precaution - If you delete the .metadata folder all preference will be deleted.
I've seen 3 other fixes so far:
in .metadata/, rm .lock file
if #1 doesn't work, try killing the process javaw.exe etc. then rm .lock file
if #1 and #2 don't work, try rm .log file in .metadata/, and double check .plugin/.
This has always worked for me: relocate .metadata/, open and close eclipse, then overwrite .metadata back
The solution boils down to cleaning up the .metadata folder.
Go to TaskManager(Right Click in the Task Bar) and select Processess menu bar and select eclipse.exe and Click EndProcess
Another possible cause of the “Workspace in use or cannot be created, chose a different one” issue is that the real path to your workspace may have changed.
In my case, the real location of the workspace had changed, but I had used a symlink to make it look like it was in the same location. I saw errors in logs indicating that eclipse was looking at the previous "real" location, as opposed to following the symlink, and this was causing the errors.
In my case, I just moved the workspace back to its old location.
There is another case where the path to the workspace may not exist, e.g., if you have imported preferences from another workspace, then some imported workspace addresses may appear in your "open workspace" dialog; then if you didn't pay attention to those addresses, you would get the exact same error once you tried to open them.
Running eclipse in Administrator Mode fixed it for me. You can do this by [Right Click] -> Run as Administrator on the eclipse.exe from your install dir.
I was on a working environment with win7 machine having restrictive permission. I also did remove the .lock and .log files but that did not help. It can be a combination of all as well that made it work.
deleting logs and .lock didn't work but
-clean option fixed it for me.
At times, if you are on Windows, you may not see all the processes - or the culprit process in Task manager. I had to click 'Show process from all users' and there was this java.exe that I had to kill in order to get back my workspace.
Another possible case if none works is to see that there is a running Java application . may be your previous open and close has left unkilled java instances.
Do look for any java instance is running if there are two at least you need to kill one.But ,most of the time i kill any java running :) because that java is using the work space earlier and still will if don't kill it.
Change another work space in case if you want a multiple IDE to use and work on diffrent or same project , but you should import project form workspace after you open your IDE.
i was faced this issue when ever the eclipse is not closed (kill eclipse process the from task manager or computer power off), i was tried below steps, it worked for me.
1) Remove the file names start with ".fileTable" from this folder
C:\eclipse\configuration\org.eclipse.osgi.manager
2) Remove the log files like text files start with numeric names from this folder
C:\eclipse\configuration
3) Open Command prompt(cmd) navigate to this folder
C:\eclipse
type below command
eclipse clean start
For Mac Users:
It could be that another instance of eclipse is running in the background. If so, use either Force Quit eclipse or
ps -ef |grep eclipse
kill -9 pid
to all the eclipse instances, and start the new workspace
Start Eclipse with the option -Dosgi.locking=none.
I got the trick here and it works.
Don't do this unless you know nobody can work on the same file at the same time.
PLease try to end task Eclipse from taskbar. It works for me.
The answer #Boris gave is correct 99% of the time, however it can also happen if you open the workspace in an older version of Eclipse. A workspace imported into/created with Juno will throw this error when opened in Galileo.
Another all-too-common reason for this problem is if you attempt to load a directory on a drive that is no longer connected. For example, Say you program in C:\Code\Java, but occasionally work off of a flash drive, H:\Code\Java. If you do not have the drive connected it can be easy to believe you are trying to load a valid directory without noticing your typo.
Another problem is when eclipse doesn't have write access to your src folder. Change the security permission and make sure "Authenticated Users" are added with all permissions checked but Full Control & Special Permissions.
I had this error after I restarted the system (after a long time. Normally I just make it sleep).
Found out that once I mounted the drives (by clicking and opening it) where project folder is located, and relaunching eclipse, solved the issue for me.
PS: I'm an ubuntu user.
Here are a few steps to solve it the no. 4 step is works for me.
Delete .log files along .metadata folder.
Check the current user permission make sure to check the full control checkbox click apply then OK.
If you run system drive defragmentation or maintenance before you run eclipse editor sometimes original file path are not in their respective path to make sure run "previous version" time before your system maintenance of your drive where the eclipse workbench or something similar to this was saved.
This last option is works for me.
Check the drive letter of your current drive where the code editor was saved. If something unusual e.g before your maintenance your drive letter is K then after defragment or maintenance.
The drive letter is now L hence you should change the drive letter to its original one that is K.
to do this click the ff:
Open control panel
System & security
Administrative tools
Computer management
Disk management
in disk mngt choose the Drive example L
then right click > change drive letter & path > click remove > then ok, open it again then > click add and > choose your original drive letter for that drive then click ok. If you use your computer for a long period of time do restart first to refresh everything.
Choosing a "different one" is actually a pretty easy solution.
I had been running Eclipse as an administrator (sudo eclipse from the command line) because the "workspace" folder was throwing the Workspace in use or cannot be created… error (and running as administrator seemed to be the only solution that fixed it).
A coworker (working on this same issue with me) wanted to run Eclipse by clicking on an icon. So when he ran Eclipse, and the dialogue box came up with the choose your workspace, he just added a "2" to the end of "workspace".
This created a new folder: "workspace2". Eclipse ran fine with that; and I haven’t had any of the locking problems since.
It will occur when you not closed eclipse.exe correctly.
*Open Task manager->End task your eclipse->Now open eclipse.exe it will work.
Hope its help someone.
I have observed one case when eclipse when in forced quit, or Alt-f2 xkilled in linux, an attempt to immediately open eclipse shows that error. Even the metadat/.lock file is not present in that case.
However it starts working after a span of about two minutes
I don't know what's the wrong but I solved by creating a directory directly in c drive(c:\dev) instead of from my home folder (c:\users\me\dev). But I don't have to thinks about it. In my case, it is fresh eclipse unziped instance. I am not able to see .matadata folder in eclipse folder. By God grace, I solved.
The reason this was happening to me (with Photon) was easily fixed by changing an Eclipse general preference:
Window -> Preferences -> General: Uncheck: "Always run in background"
Once you make that change, whenever you shutdown Eclipse, it will no longer leave the javaw.exe process running in the background. I’m guessing this is a bug in Photon (or a bug with using the Amazon Corretto OpenJDK version of Java with Eclipse) that will one day be fixed.
I faced the same problem, but for some reasons the .lock file in workspace was not getting deleted. Even creating a new workspace was also getting locked.
So what I did was cleaning the windows temp folder, the %PREFETCH% folder and %TEMP% locations. Restart the system and then it allowed to delete the .lock file.
Maybe it will help someone.
It seems your workspace is used in Java TM, Open task manager and close eclipse.exe and java TM process.
What worked in my case was restarting the system. (ubuntu 20.04)
If anyone have come here with a STM32Cube related issue, which apparently is based on Eclipse and has the same problem, none of the above suggestions worked for me, and here is how I fixed it, for Linux, although I suppose you can find the corresponding paths in Windows as well.
In the $HOME directory, go to .eclipse/com.st.stm32cube.ide.../configuration/settings
The file org.eclipse.ui.ide.prefs contains few options including the recent workspace path, and whether it will prompt you to select a workspace at the startup. Either modify the path for RECENT_WORKSPACES, or enable SHOW_WORKSPACE_SELECTION_DIALOG.
In my case, there was a space right before the workspace's location C:\. I removed that space and it was enough :)

Portable Eclipse

I'm trying to port my entire 'workspace' to a USB key (including the Eclipse executable) so that I can carry my work anywhere with me and work off the key directly.
My directory hierarchy is similar to this:
/workspace/eclipse - Where my current eclipse binary is stored
/workspace/codebase - Where I keep the root of all my eclipse projects
/workspace/resources - Where I keep all project files (images, docs, libs, etc.)
It all works perfectly fine on one system. But when I change over to another system, the USB key gets mounted on another drive. For example, on my laptop, I get 'E:\', on my PC, I get 'K:\' and at work I get 'F:\', etc, etc.
This means that because Eclipse (for 'some' reason) seems to only use full path names (including driver letters) in every single one of its configuration files (such as .classpath), nothing ever works when I want to work on another system.
I put a 'libs' directory in the base of every project and populate it with its dependent JAR files. Why doesn't it use relative names instead, so that I could specify something like "../../libs/log4j.jar"?
Anyone know how to fix this problem? Does anyone know of a workaround for this?
Update: 2010.11.09
I've recently discovered Dropbox, which allows you to sync your files online and across your computers automatically with extreme ease. It includes 2GB of free space and you can upgrade to much more if you want (for a yearly fee).
I installed it on my two laptops, my two PC's, my Linux server and my Android phone and then I created a 'workspace' directory within the 'My Dropbox' folder. From the 'workspace' directory, I then installed Eclipse and created/configured all my projects as usual. I can literally work from any computer and everything always stays perfectly in sync. This is way better than any USB key functionality and its hassle!
Have you tried using Eclipse Portable?
The only thing to keep in mind is that when switching the workspace, you need to remember to give it a relative path (like ../../Data/workspace).
You could use the dos command subst to get a consistent drive letter by creating a new virtual drive letter (say x:) that maps to your Eclipse folder on your usb drive, and then make all the config paths reference the drive x:
You could make a little batch file on the usb drive that you click on to create the drive x:
C:\>help subst
Associates a path with a drive letter.
SUBST [drive1: [drive2:]path]
SUBST drive1: /D
drive1: Specifies a virtual drive to which you want to assign a path.
[drive2:]path Specifies a physical drive and path you want to assign to
a virtual drive.
/D Deletes a substituted (virtual) drive.
Type SUBST with no parameters to display a list of current virtual drives.
You could also remap letter for your USB stick in Windows Disk Management (subitem in Computer management) to be smth like 'U:'.
Once done, it will be re-assigned to same stick every time you plug it. Not very universal, since your user need rights to access this setting first time, but it could help in some different scenarios.
You can always use Ant to build your programs, with Ant you can have relative paths... Plus you can also use Ivy to track dependencies in Ant, I do that in every project that I have.
Another alternative is to manually edit your .classpath files to contain relative paths.
It is a bit of a hassle, though, as you'll have to manually update the files whenever Eclipse changes them.
