comlink | Comlink makes WebWorkers | Runtime Evironment library

I want to use webcamera to get frame and run tensorflow model "handpose" for estimating hand visibility. As we know, handpose model is a little slow so i try to move estimating to web worker.

the problem is HTMLVideoElement object could not be cloned. (I need to pass video to estimateHand method).

Is it possible to do it in another way?

web worker:

I created a rust-wasm module and use workerize-loader to load it:

I am trying to lazy load a module containing WebWorkers in Angular 7, using worker-plugin and Comlink. Basically, I've followed the tutorial from here and it compiles and works fine.

When running ng serve, it crashes on the first reload with TypeError: Cannot read property 'kind' of undefined.

The code is on GitHub. https://github.com/jetkiwi/angular-comlink-lazyload-example

I am able to fill the new row with the values of the previous row. I can assign constants to vars in the new row. But, I cannot calculate values based on previous rows and assign them in the new row.

I have real data from a PLC, that I prepare for conversion to an eventlog for use with bupaR. The data below are limited and simplified but contain information concerning resource, timestamp, state-type, and event_ID.

• I added Error_ID, Error_startTS, Error_EndTS, and part of the Life-cycle, as was documented in another SO question
• An Error is defined as any series of events that starts with the state_type=="error", until an event is encountered that is anything but "Error", "Comlink Down", "Not Active".
• an error number was assigned to all rows of the same "error-trace" ("Error_ID")
• the start time of the error (timestamp of 1st error row) was assigned ("Error_startTS")
• the end time of the error,, the timestamp of the 1st row after the error, in other words the timestamp of the event that ends the error was assigned ("Error_endTS")
• a "Life_cycle_ID" was assigned to the rows of the error, either "Start" or "Ongoing".

Now, I want to insert a new row

• with Life_cycle_id == "Complete"
• after the last row of "ongoing" of each "error-trace"

Details

• Solvable with fill(): copy from last row
  • "Resource"
  • "Error_ID",
  • "Error_startTS",
  • "Error_endTS"
• Solvable with add.row(): assign a constant
  • "Lifecycle_ID" should be "Complete"
  • "State_type" should be "Error"
• Problematic for me: assign values base on values of the previous rows
  • The time-stamp "Datetime_local" should get the value of "Error_endTS" in the group
  • the "event_ID" should be increased by 1

I am newbie to postgresql and I need a postgresql version of this function - could you help me please?

Lets say I have a blog and a class user in a model. Furthermore I have a class comment connected with a foreign key.

I want to modify an existing variable on a remote machine. On a local machine I use 'sed' for that. But how can I achieve this on a remote machine?

comlink.sh: The remote file containing the variable that should be changed.

I try to import variables of a remote bash script via ssh.

Remote file comlink.sh:

I am new to coding and already found a few topics about this on stackoverflow, but couldn't make it work, as they seem overextended to me. I might need some guidance.

I need to change some variables in an external bash script 'comlink.conf'. But only specific ones. Others should be left like they are.
