What other .env files can be used?

Note: this feature is available with react-scripts@1.0.0 and higher.

• .env: Default.
• .env.local: Local overrides. This file is loaded for all environments except test.
• .env.development, .env.test, .env.production: Environment-specific settings.
• .env.development.local, .env.test.local, .env.production.local: Local overrides of environment-specific settings.

Files on the left have more priority than files on the right:

Kubectl plugin

This plugin adds completion for the Kubernetes cluster manager, as well as some aliases for common kubectl commands.

To use it, add kubectl to the plugins array in your zshrc file:

plugins=(... kubectl)

Memory profiling Rust code with heaptrack in 2019

I recently ran into a classic case of "our code is using way more memory than it should". So I took my first dive into memory profiling Rust code. I read several posts about this, including the following

• KodrAus' gist on profiling rust
• This reddit thread
• Brendan D. Gregg's post about memory flamegraphs
• Bradlee Speice's A Case Study in Heaptrack

/* Basic example of saving cookie using axios in node.js and session's recreation after expiration.
 * We have to getting/saving cookie manually because WithCredential axios param use XHR and doesn't work in node.js
 * Also, this example supports parallel request and send only one create session request.

const BASE_URL = "https://google.com";

// Init instance of axios which works with BASE_URL
const axiosInstance = axios.create({ baseURL: BASE_URL });

AWS Presigned URLs

Presigned URLs are useful for fine-grained access control to resources on s3.

For example, if storing larger text blocks than DynamoDB might allow with its 400KB size limits s3 is a useful option.

Ignoring various ACL methods and using presigned URLs, it's possible to create lambda functions that can generate the required upload and download URLs.

Using the default IAM roles and lambda proxy configuration of serverless, lambdas are assigned an IAM role for the application (so that a logical group of functions can share resources - e.g. for a CRUD REST API). Each function then assumes the IAM role via its own function name.
