QUESTION
I updated from ruby 2.7.1 to 3.1.1, then removed Gemfile.lock and ran bundle update
(it's on a dev branch, so I can throw it away if this is a bad idea, I just wanted to see if it would work).
bundle update
succeeds, but when I start the server:
ANSWER
Answered 2022-Mar-19 at 10:21The problem is related to the Ruby 3.1 / Psych 4.x incompatibility described in this issue: https://bugs.ruby-lang.org/issues/17866
Ruby 3.0 comes with Psych 3, while Ruby 3.1 comes with Psych 4, which has a major breaking change (diff 3.3.2 → 4.0.0).
- The new YAML loading methods (Psych 4) do not load aliases unless they get the
aliases: true
argument. - The old YAML loading methods (Psych 3) do not support the
aliases
keyword.
At this point, it seems like anyone, anywhere that wants to load YAML in the same way it worked prior to Ruby 3.1, need to do something like this:

QUESTION
Is there a straightforward way to to get the coordinate points of an agent in relation to main
when that agent is the lower agent of multiple other agents?
For example:
I have a Box agent.
There are populations of Box
agents in both my Shelf
and Pallet
agents, and the Pallet
agents can be located either in the main
or Rack
agents.
So I've got:
main
> Shelf
> Box
main
> Pallet
> Box
main
> Rack
> Pallet
> Box
So far, I've created individual hard-coded functions that add up the coordinate of the Box with the coordinates of its upper-level agents.
So:
For boxes in pallets in racks: CoordBoxInMain = CoordBox + CoordPallet + CoordRack
For boxes in shelves: CoordBoxInMain = CoordBox + CoordShelf
But now I am wondering, is there a way to construct a single function that directly gets the coordinates of my Box
agent without having to create multiple different functions that each refers to a different sequence of upper-level agents?
Thank you.

QUESTION
I have been asked to remake the excel workbook to index where we keep the items. I have an excel sheet with a table ( excel table) that contains the information.
If the there the value in column 6 ="10" then that means the item is in box 10. then I need to get the right shelve, this is found by the numbers in column 7 (shelve) and 8 (rack). subsequently the information about the item has to be put in another sheet which gives a visual representation of the box.
I am struggling to get the desired result, does anyone have some suggestions?

Answered 2022-Feb-03 at 10:55Please, try the next code. It will iterate in the table DataBodyRange

Good morning people.
I'm trying to understand the error below but as I'm new to rails, I didn't quite understand. Does anyone have a light on what it could be?
I searched the internet but didn't find anything specific.
I searched on the internet but didn't identify anything, if anyone has seen it or has the link, you can send me and I'll see.
If you need any more information to help, let me know and I'll edit the post and add it, I don't know if there's anything else I could have already posted.
thank you for your help !!

Answered 2022-Jan-21 at 13:34First of all, the message about DidYouMean
is a deprecation warning not an error, it doesn't break your app. It means that usage of DidYouMean::SPELL_CHECKERS
is deprecated and will be removed in a future version of ruby. In this case in Ruby 3.3. You shouldn't worry about it until you use versions that are lower than 3.3.
It's not your code that triggers the warning. It comes from a gem named Thor. The issue was solved in thor version 1.2.0. You can update the gem by calling bundle update thor
.
The actual error comes from the bootsnap

We have a bunch of microservices based on Spring Boot 2.5.4 also including spring-kafka:2.7.6
and spring-boot-actuator:2.5.4
. All the services use Tomcat as servlet container and graceful shutdown enabled. These microservices are containerized using docker.
Due to a misconfiguration, yesterday we faced a problem on one of these containers because it took a port already bound from another one.
