NDJSON is a convenient format for storing or streaming structured data that may be processed one record at a time.

• Each line is a valid JSON value
• Line separator is ‘\n’

1. Convert JSON to NDJSON?

cat test.json | jq -c '.[]' > testNDJSON.json

#!/usr/bin/env bash

set -e

wget \
  --recursive \
  -c \
  --level=inf \
  --page-requisites \
  --convert-links \

Client-side SSL

For excessively paranoid client authentication.

Original: https://gist.github.com/mtigas/952344

Convert SSL certificate from CRT format to PEM

openssl x509 -in server.crt -out server.der -outform DER
openssl x509 -in server.der -inform DER -out server.pem -outform PEM

1. Dump the data only sql to file
  $ pg_dump --data-only --inserts YOUR_DB_NAME > dump.sql
2. scp to local

3. Remove the SET statements at the top
  such as:
    SET statement_timeout = 0;
    SET client_encoding = 'SQL_ASCII';

4. Remove the setval sequence queries

Problem

I have a notebook connected to a port replicator. I want to use the build-in speakers and microfone and not the external ones. If I boot my notebook in my port replicator Ubuntu changes the devices to external.

Solution

1. Find your internal speaker

Implementing a jq REPL with fzf

Update: I created jq-zsh-plugin that does this.

One of my favourite tools of my trade is jq. It essentially enables you to process json streams with the same power that sed, awk and grep provide you with for editing line-based formats (csv, tsv, etc.).

Another one of my favourite tools is fzf.

#   copy this script into INSTALL_DIR
#   rootinit after entering chroot
#   x (if installing graphics)
#   pkgs
#   xpkgs (if installing graphics)
