Use mkcert mkcert -install mkcert localhost # creates two localhost.pem (cert) and localhost-key.pem (key) file provide the key and cert file to the http server program.

When you use an import statement in your code, the Python runtime searches the directories in its search path until it finds the module or package.

Check your /etc/hosts So ran into this stupid error where lnd was not starting because it was trying to lookup localhost and it couldn’t resolve it so it asks the DNS server (1.1.1.1) and obviously can’t resolve it either. failed to load config: lookup lo…

Faced an issue where I would get stuck in a redirect loop when configured a cloudflare dns as ‘proxied’.

Although s3 has a flat structure—unlike a filesystem—it has a concept of “folders”.

These are notes that I took while reading the The Go Prgogramming Language book Interesting points Go has some strictness when it comes to compiling if packages are imported but not used - don’t compile if a newline is placed incorrectly - don’t compile.

Wrote the following in the FOSS United Telegram group, might expand this later as a blog post.

If you want to give access to everything in the bucket (objects) make sure the resource arn for the s3 bucket must also have a /* indicating all objects in the bucket "Resource": [ "arn:aws:s3:::BUCKET-NAME", ] This one won’t give access to objects in…

There are two ways to manage access of a bucket - user policies or resources policies.

tldr; ECS is just AWS’s proprietary orchestration solution.

xxd is a great tool.

playwright is really good for browser automation.

TIL from RFC2732 that the way you access an ipv6 address in a browser is by enclosing it in square brackets http://[2401:4900:f00b:dead:2f2d:48ac:9fdb:b7ff]:8080/path/file.txt
