I need to get product collection by filter multiple category ids in magento 2

I need to get product collection by filter multiple category ids.

Here is my code:

$  cat_id = [2,3,5]; $  productcollection = $  objectmanager->create('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory'); $  categoryProducts = $  productcollection->addAttributeToSelect('*')->addAttributeToSort('position', 'ASC')->addCategoriesFilter(['in' => $  cat_id])->addAttributeToFilter('color', array('in',$  colorvalues)); 

But this code is not working.

What’s the best approach when you need to work off two branches that still have pending PR requests?

Let’s say I have branch-1 (branched off master (major update)) and branch-2 (also branched off master (minor update)).

What is the best approach to do when I need to create another branch, e.g. branch-3 and I need to continue the work from both branches while their PRs are still pending?

And what do I do once both the PRs have been approved?

Why do we need to chain the blocks (creating blockchain) in a permissioned blockchain?

The main question is:

What does “chaining block” mean in a permissioned blockchain? OR in any blockchain network in which creating a new block does NOT need consuming resources/energy ? (even in the case of proof-of-stake)

Does “chaining blocks” (creating blockchain) WITHOUT consuming resources (in the case of PoW, this resource is electricity) make sense? where, re-calculating all hash values does NOT have any considerable cost and it takes few seconds.

In other words, Why do we need to chain the blocks (creating blockchain) in a permissioned blockchain network (such as Hyperledger whose consensus mechanism is PBFT)?

What does really mean chaining blocks without consuming resource/energy? where re-calculating all hash values and as a result replacing all blocks can be done EASILY and RAPIDLY.

The thing can make transactions history immutable in Bitcoin, is a PoW with enough difficulty and not only using blockchain data structure. Otherwise, only chaining blocks based on ex. a PBFT consensus (or even based on proof-of-stake) can be interpreted as a fallacy.

What is the role of blockchain (chained blocks) in a permissioned network? where if one is able to change one block, then he could change the whole of chain as well, by re-calculating all previous hash values, since there is NO difficulty to calculate hashes.

Note: I tried to bring up my question in several different forms to be more clear. In the case, you think some additional explanation is need, please let me know.

I NEED TO BUILD A NEW NETWORK AT WORK

10 computers and they all need to get on the cloud. I like them with all the chit in the screen and no boxes on the floor. I have an IT guy but he picks shittty arse computers to me.
For 750/ computer, what should I get?
Provide a link from Amazon (where we buy everything just about) please
I want them to be fast, fast , fast. We have killer good internet now (100 mbps down and 20 up) so that should not be an issue. I know we probably can get a good one for less than 750 but we use them…
