How to manage access to shared resources using Project Reactor?

Given an imaginary critical component that can execute only operation at the time (file store, expensive remote service, etc), how could one orchestrate in reactive manner access to this component if there are multiple points of access to this component (multiple API methods, subscribers...)? If the resource is free to execute the operation it should execute it right away, if some other operation is already in progress, add my operation to the queue and complete my Mono once my operation is completed.

My idea is to add tasks to the flux queue which executes tasks one by one and return a Mono which will be complete once the task in the queue is completed, without blocking.

I'm building a staking function and hitting the following error after giving permission to access my token:

"MetaMask - RPC Error: Cannot set properties of undefined (setting 'loadingDefaults')"

Hello I am trying to transfer a custom SPL token with the solana-wallet adapter. However i am having trouble getting the wallet's secret key/signing the transaction.

I've looked at these answers for writing the transfer code but i need to get the Singer and i have trouble figuring out how with solana-wallet adapter. These examples hardcode the secret key and since i'm using a wallet extension this is not possible.

How can you transfer SOL using the web3.js sdk for Solana?

How to transfer custom token by '@solana/web3.js'

according to this issue on the webadapter repo https://github.com/solana-labs/wallet-adapter/issues/120 you need to:

1. Create a @solana/web3.js Transaction object and add instructions to it
2. Sign the transaction with the wallet
3. Send the transaction over a Connection

But i am having difficulty finding examples or documentation as to how to do step 1 and 2.

I want to encrypt data in a web browser that is send to my C# backend and decrypted there.

That fails because I am unable to decrypt the data generated on the frontend in the backend.

Here's what I did so far.

First I created a private/public key pair (in XmlString Format). I took the ExportPublicKey function to generate the public key file from here: https://stackoverflow.com/a/28407693/98491

I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):

encountered RSA key, expected OPENSSH key

Executing the same command from the system shell (using the same private key of course) works perfectly fine.

On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:

userauth_pubkey: unsupported public key algorithm: rsa-sha2-512

Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.

It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

I want to use dplyr::coalesce to find the first non-missing value between pairs of variables in a dataframe containing multiple pairs of variable. The goal is to create a new dataframe with now only one copy for each pair of variable (a coalesce variable without NA values).

Here is an example:

I am querying the Covalent database in order to get information about rUSDT token Transfer transactions on RSK. The token address on the RSK blockchain is as below:

0xEf213441a85DF4d7acBdAe0Cf78004E1e486BB96

The transfer event log's hash is as below:
