i often am annoyed with the generality and complexity of existing solutions, and seek something simpler. additionally, that which i cannot build, i do not understand. to summarize: building things, for fun and profit. agr: https://github.com/nathants/agr like ag or ack, but with the ability to replace matches or delete lines. tinysnitch: https://github.com/nathants/tinysnitch a minimal system firewall for inbound/outbound connections with visual prompts on connections without an existing rule. fails closed. cli-aws: https://github.com/nathants/cli-aws a cli for working with aws, particularly ec2 and lambda, that dramatically simplify operations. currently exploring a go port. bsv: https://github.com/nathants/bsv a binary data format and composable tools for maximum performance data processing. several tools have triplicate implementations

in go and rust for performance experiments. generative testing with small and varying buffer sizes ensure correctness. prototype with pipes, optimize with a single binary (see related posts in readme). s4: https://github.com/nathants/s4 maximum performance distributed object storage with adhoc distributed computation and data shuffle. duplicate implementations in go and python, for fine grained objects prefer go, for medium and coarse grained, use either. use with ephemeral data and instance local storage (i3en). prefer vendor object storage for durability.
In Ask HN: What are some tools / libraries you built yourself?
> There isn't even a single decent dynamic firewall with those annoying popups. even benign apps that phone home like pulumi and terraform are fun to see and block with annoying popups. monitoring egress really is the only realistic play. i rolled my own[1], inspired by opensnitch[2]. netfilter_queue is really great, and definitely makes annoying popup dynamic firewalls possible. 1. https://github.com/nathants/tinysnitch 2. https://github.com/evilsocket/opensnitch
