What kind of Windows 10 NTFS file objects are these?

Asked 2021-Jun-13 at 09:28

I'm looking at a fresh out of the box, Windows 10 laptop.

Under the folder C:\Users\John.Doe\Documents File Explorer shows three "folders":

My Music
My Pictures
My Videos

I cannot see or access these "folders" from PowerShell nor the old cmd shell.

They do not appear to be shortcuts, symbolic links, hard links, or junction points.

What else is there? They appear to be some sort of reparse point but what? And how can they be detected by PowerShell?

They're junctions, at least according to the DIR command (which generally does not make things up).

In your particular case why not just include the actual quotes into the macro parameter value instead of adding them in the macro?

Traversing multiple symbolic links recursively in Python

Asked 2021-Jun-10 at 15:37

I want to write a recursive function to traverse symbolic links from source path to destination path

Example: 1)readlink patha/pathb/pathc -> gives if symbolic link exists 2)readlink patha/pathb/pathc/ -> gives if symbolic link exists

I'm using os.readlink method in python to get symbolic link in Python but how to traverse multiple symbolic links

Reason for traverse: If its in future someone wants to add file3 symbolic link in between , then I wanted a recursive function to traverse each symbolic links and gives the final dest path
file1 -> file2 -> .... -> for getting destination path

QUESTION

How do I take gradients of MultibodyPlant computations w.r.t. mass, center-of-mass, inertia, etc.?

Asked 2021-Jun-09 at 12:41

I see the current chapter of Underactuated: System Identification and the corresponding notebook, and it currently does it through symbolics.

I'd like to try out stuff like system identification using forward-mode automatic differentiation ("autodiff" via AutoDiffXd, etc.), just to check things like scalability, get a better feel for symbolics and autodiff options in Drake, etc.

As a first steps towards system identification with autodiff, how do I take gradients of MultibodyPlant quantities (e.g. generalized forces, forward dynamics, etc.) with respect to inertial parameters (say mass)?

Note: Permalinks of Underactuated chapter + notebook at time of writing: sysid.html, sysid.ipynb

...

ANSWER

Answered 2021-Jun-09 at 12:41

Drake's formulation of MultibodyPlant, in conjunction with the Drake Systems framework, can allow you to take derivatives (via autodiff) with respect to inertial parameters by using the parameter accessors of RigidBody on the given plant's Context.

Please see the following tutorial:

QUESTION

Shared folder permission anomaly with linux

Asked 2021-Jun-09 at 09:43

So, i have this shared folder symbolically linked to 'shared'. The folder is associated to 2 user (bill and karen) who both has membership of 'bill-karen' group. Problem is, i can't seem to create a new file from both user unless I run a new shell with su - [USER]

This seems odd to me as the folder is owned by root:bill-karen while the permission for the folder is 2775 (-rwxrwsr-x). Is there any reason behind this? I'm using ubuntu 20.04 LTS anyway.

How i configured the shared folder: *Note that i already has user bill

QUESTION

Java has too many level symbolic links

Asked 2021-Jun-09 at 06:59

Well,I was trying to install forge on my linux machine(Kali-Linux).While on the was I was and still am unable to access the forge file(.jar).Due to an issue in which there is a lack of a command called "java".

The current problem I am having is sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-16.0.1/bin/java 1 while using this command I get a response as update-alternatives: error: cannot stat file '/bin/java': Too many levels of symbolic links. When I try to ls in the /bin.The java symbolic link has a weird symbol(Just wanted to mention it cause it looked weird)

Is there anyway to fix this problem?

...

ANSWER

Answered 2021-Jun-09 at 06:59

The "too many levels of symbolic links" message means that 40 symlinks have been traversed in attempting to resolve a path to an object.

It nearly always happens because you have a symlink that directly or indirectly points to itself. And the purpose of the limit (and the check) is to prevent the kernel going into an infinite loop.

So, why it is it happening here? Well, it is not entirely clear. But it seems like an earlier update-alternatives run has left some "wreckage" in the form of bad symlinks. If "/bin/java" already points to "/etc/alternatives/java", then "/etc/alternatives/java" should be a symlink to ... somewhere else.

Try the following:

Use update-alternatives --remove-all java to clear out any alternatives for the java command. (If this fails with the same problem, try step 2 first, then retry this step. Adding --force might help too.)
Remove the "/bin/java" and "/usr/bin/java" symlinks if they still exist.
Make sure that you have actually installed Java (already!), and "/usr/lib/jvm/jdk-16.0.1/bin/java" is the correct path for the executable. Run /usr/lib/jvm/jdk-16.0.1/bin/java -version to check.
Run sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-16.0.1/bin/java 1.

Note that update-alternatives does not actually install anything. For the command to work properly, you need to have installed (in this case) a Java JRE or JDK or a Kali Java package already.

Note that it cannot do any real harm to remove "alternatives" symlink chains that are broken. You can always clean them out and rebuild them. (By hand, if necessary.) The alternatives mechanism is just a fancy way of managing symlinks.
