Ask HN: What simple tools or products are you most proud of making?

Definitely different from the ones here since it hasn't made me loads of money, but definitely proud of it.

The first web application I ever made, which was actually based on one of those Ask HN threads we had 2+ years go about looking for furniture the fit a specific size. I actually did make a few sales, shockingly.

At this point, it's pretty much dead as I've taken in other projects and independent security consulting engagements. It was extremely useful understanding the entire stack, and I've found it to be something I've been able to use to build a bridge to developers.

I've recently developed a writing system of Arabic in Latin alphabet that I believe will be very useful for Arabic learner to improve their reading and writing skills in Arabic.

Please check it out and let me know what you think.

It parses DSV data like Awk does, runs SQL queries against it and formats the output in one of several ways. An example I am particularly fond of is using this tool as a poor man's libxo (https://github.com/Juniper/libxo):

  $ ps | sqawk -output json,indent=1 'select PID,TTY,TIME,CMD from a' trim=left header=1
  [{
      "PID"  : "3947",
      "TTY"  : "pts/2",
      "TIME" : "00:00:07",
      "CMD"  : "zsh"
  },{
      "PID"  : "15951",
      "TTY"  : "pts/2",
      "TIME" : "00:00:00",
      "CMD"  : "ps"
  },{
      "PID"  : "15952",
      "TTY"  : "pts/2",
      "TIME" : "00:00:00",
      "CMD"  : "tclkit-8.6.3-mk"
  }]

Helps people read more easily on-screen. Originally designed as a speed-reading tool for lifehack types, but it turns out to also be super effective as an assistive technology for people with dyslexia, vision impairments, and executive function disorders.
