toolbox | Golang Tools - This is my toolbox

I can't open Android Studio 2020.3.1 Arctic Fox. On Kubuntu 20.04. An error pops up:

All I'm trying to accomplish right now is get my custom component to show up in the SSIS Toolbox. I've been looking everywhere I can think of for any information about creating a custom Data Flow Component in Visual Studio 2019. I have found plenty of out-dated examples and solved problems, none of which help me solve my problem.

Based on Microsoft's description of how to do this, you would think all you have to do is follow their instructions and it'll work. Not so, at least not for me yet.

Here's what I've done so far in an attempt to simplify and get anything to work:

1. I Created a class library and referenced the following assemblies:

• Microsoft.SqlServer.DTSPipelineWrap
• Microsoft.SQLServer.DTSRuntimeWrap
• Microsoft.SQLServer.ManagedDTS
• Microsoft.SqlServer.PiplineHost

1. Inherited from PipelineComponent and added the DtsPipelineComponent attribute.

2. Overridden methods (code below)

3. Signed the assembly

4. Created Post-build events to install into the GAC and copied the assembly to the C:\Program Files\Microsoft SQL Server\130\DTS\PipelineComponents folder.

5. In an SSIS project, I do a refresh on SSIS Toolbox and my component does not show up. I've tried Browsing to the assembly by going to Tools >> Choose Toolbox Items and selecting the assembly.

I get this message:

Here is my simplified code that does nothing: Sorry about having posted it using an image, but using the recommended code highlighters don't work for me either.

Here is a screenshot of the GAC listing:

I must be missing something.

Any help or ideas would be greatly appreciated. If I can't get this to work, I'll have to punt and resort to a Script Component transformation. Really hate to do that as that means each developer will have to maintain a lot of extra code.

Thank you in advance.

I am trying to find the end-effector spatial velocity Jacobian for a robot with a free-floating base. Due to the free-floating base, the jacobian should contain a base component and a manipulator comment (see https://spart.readthedocs.io/en/latest/Tutorial_Kinematics.html#jacobians)

V_ee = end-effector spatial velocity
J_b = base jacobian component
J_m = manipulator jacobian component
v = generalized velocities

V_ee = [J_b, J_m] v

Until now, I was using SPART toolbox to do this in Matlab (https://github.com/NPS-SRL/SPART) and now I am moving to Drake. I tried using CalcJacobianSpatialVelocity in the MultiBodyPlant and the manipulator Jacobian is correct when compared to SPART. However, the base component of the Jacobian is all zeros. This is different from what I expected and from SPART as for a free-floating base, the base velocities contribute to the end-effector spatial velocities.

An example reproduction of this issue can be found here: https://colab.research.google.com/github/vyas-shubham/DrakeTests/blob/main/freeFloating/computeJacobian.ipynb

I think I'm either doing one of these wrong while using Drake:

• Using the CalcJacobianSpatialVelocity wrong. This is unlikely as the manipulator jacobian is correct and the base frame is also correct (only 1 frame in URDF).
• Making a wrong URDF for calculating Jacobians for Free-Floating base. Maybe I need to specify differently in URDF a floating-base for Drake to include this in the Jacobian computation?

I am trying to retrieve step counts from a smartwatch and push it to API. I was able to retrieve and push the data when I open the app. But once it is not activated, then it will not send any data. I am trying to use the android service to run the app in the background so that it will send the data continuously. I have given all the permissions and enabled them.

This is MainActivity.java

I was following instructions from https://developer.here.com/documentation/flutter-sdk-navigate/4.4.0.2/dev_guide/topics/quick-start.html#try-the-example-apps both for trying example apps or creating a new project. Neither seems to work. Running fails with the following errors:

Let's say I have the following Django models:

I used Compute Engine VM with T4 GPU for quite some time on COS and it has been working fine until recently that cos-extensions install gpu does not work like before.

After updating to Android Studio Arctic Fox, I cannot choose any of my installed themes. Invalid cache and restart didn't help ;) Also reinstalling themes still not solving this problem.

I updated AS 4.2 to Arctic Fox using Toolbox on the stable channel. I'm on win 10.

Maybe someone has an idea how to solve this issue?

I want to ultimately print the verse number, e.g. §1, encoded in the XML as , in my pdf output. Here's an example of my XML document:
