Crypto development resources

This document pretends to be a comprehensive (and of course constantly updated and outdated) compilation of many sources I have been using since I started in crypto in 2016. Most of the content is in English🇬🇧, but since we wanted to share the knowledge with the audience that comes from Latin America, we have collected some resources in Spanish🇪🇸 as well. We followed the awesome DeFi Developer Roadmap as the main guidance for completing this work. Feel free to share, make contributions, deletions and critics to this document, we are all here to learn and build!

Hiring Without Hardship

A list of companies (or teams) that don't do "whiteboard" interviews. "Whiteboards" is used as a metaphor, and is a symbol for the kinds of CS trivia questions that are associated with bad interview practices. Whiteboards are not bad – CS trivia questions are. Using sites like HackerRank/LeetCode probably fall into a similar category.

The companies and teams listed here use interview techniques and questions that resemble day-to-day work. For example, pairing on a real world problem or a paid/unpaid take home exercise. Read (and contribute to) our recommendations for ways to conduct better interviews.

tl;dr

• Discussing a real world problem (with or without whiteboard) is 👍
• Solving CS trivia, technical puzzles, riddles, brainteasers (with or without whiteboard) is 👎

Falsehoods that Ethereum programmers believe

I recently stumbled upon Falsehoods programmers believe about time zones, which got a good laugh out of me.

Multi-node-training on slurm with PyTorch

What's this?

• A simple note for how to start multi-node-training on slurm scheduler with PyTorch.
• Useful especially when scheduler is too busy that you cannot get multiple GPUs allocated, or you need more than 4 GPUs for a single job.
• Requirement: Have to use PyTorch DistributedDataParallel(DDP) for this purpose.
• Warning: might need to re-factor your own code.
• Warning: might be secretly condemned by your colleagues because using too many GPUs.

Abstract

BlockchainのScalability問題を解決するソリューションの1つとしてLayer2のState Channelがある。2015年にBitcoinのLayer2ソリューションとしてLightning Networkが提案された。 当初はBitcoinやEthereumのLayer2として語られていたが近年様々なState Channelソリューションが登場している。そこで本論ではBlockchainのScalability問題解決の有力なソリューションとされているState Channelについて調査し、まとめることにする。
