CW contract signature

The use of smart contracts (multisig, smart contract wallet) does not provide valid signatures from signature schemes. This is a limitation as EOA (externally owned accounts)

• has a clear signature-client interface to sign arbitrary (or standard login) messages
• can provide signature verifiable in contracts, such as for gas provision in smart contract wallets

This is similar to the isValidSiganture standard in Ethereum.

Support for Cosmos SDK Stargate in CosmJS has been ongoing work for several months now. Stargate is released and CosmJS is here to connect to it.

Starting points

Let's explore what is new for Stargate support:

• @cosmjs/proto-signing, which implements the new SIGN_MODE_DIRECT based on protobuf serializations
• @cosmjs/stargate, which provides a high level client for querying, signing and broadcasting
• @cosmjs/cosmwasm-stargate for interacting with CosmWasm smart contracts on Stargate chains

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
