I had a unclean shutdown less than a day ago and got this warning afterwards:

WARN [03-26|10:10:29.944] Unclean shutdown detected booted=2021-03-17T13:16:42+0000 age=1w1d20h

As it would be better to have the "age=" part closer to the shutdown @holiman suggested to update the marker like every 5 minutes

Consider the following error message reported by the Move compiler.

use MyPackage::MyCoin::{Self, MyCoin};
   │           ^^^^^^Unused 'use' of alias 'MyCoin'. Consider removing it

You get this message when the module has no calls to functions in MyCoin. The correct fix is removing the Self from the use declaration. But:

• the error message mentions MyCoin, which might mak

Original title: "unusual behavior with mapping within struct within library".

Description

When a library contains a struct type whose only member is a mapping, and a contract contains a public member of that struct type, then compilation fails with error Internal or recursive type is not allowed for public state variables.. But if you add a further field in the struct (of type `

Per stackoverflow post https://stackoverflow.com/questions/69115892/hyperledger-fabric-java-chaincode-timeout-expired-while-starting-chaincode  , it appears Java chaincode is missing from chaincode as an external service doc topic:

Issue

Vyper handles unmapped instructions differently from Solidity. In Solidity, unmapped instructions are given a file index of -1. When attempting to show the source for such an instruction, we instead just show 1: // No source code found..

However, in Vyper, such instructions are not given a file index of -1, but are given a start and length of 0. So when we show the source for t

Problem

fromAccountData() seems to be broken. Tried several vote accounts with the same result. Script is for mainnet, but on the testnet it fails in the exact same way. Tried @solana/web3.js releases 1.29.1 and 1.29.2

Background

If my node is asked to forward N sats to peer X via channel C, lnd is free to pick any other channel it might have to peer X. As far as I understand the code (switch.go:handlePacketForward), all channels to X (not just C) are checked for eligability, and a random eligable channel is then used for the actual forward.

As part of this eligability check (implemented in link.go:Che

A parametrized option to set the blocksize would be useful to experiment with. As quorum is used in a private setting I think this option should be available
