Oveheard : Pain

our ability to deal with pain is directly proportional to our ability to see pain elsewhere.

HOWTO : Query json data in SQLite

A self note for querying json data in SQLite. BTW, I think SQLite is an under utilized and under appreciated swiss army tool for data storage and manipulation. And thanks to Richard Hipp, it is free.

If you have a column defined as a json type in your SQLite database, quickest way to search for the data is json_extract. A full set of functions available are documented at https://www.sqlite.org/json1.html

If you have a column named family_details in a table family with the following json in it as an example 

{
	"father": {
		"name": "dad",
		"birthday": "1/1/2000",
		"pet_name": "daddy"
	},
	"mother": {
		"name": "mom",
		"birthday": "1/1/2001",
		"pet_name": "mommy"
	},
	"sons": [
		{
			"name": "son_one",
			"birthday": "1/2/2020",
			"pet_name": "sonny_one"
		},
		{
			"name": "son_two",
			"birthday": "1/2/2021",
			"pet_name": "sonny_two"
		}
	],
	"daughters": [
		{
			"name": "princess_one",
			"birthday": "1/2/2020",
			"pet_name": "princy_one"
		},
		{
			"name": "princess_two",
			"birthday": "1/2/2021",
			"pet_name": "princy_two"
		}
	]
}

and you want to print the name of the father, you can use

select json_extract(family_details, '$.father.name') as father_name
from family

json_extract uses the name of the column and the json node as parameters. In this case, we used $(which denotes the root), father and name (under father) as the json node.

Overheard : Services vs Product businesses

In the services business, you get paid to say yes to everything.

In the product business, you get paid to say no. By convincing the customer that you are not going to give what they want, but what they need.

Overheard : On appreciation

Everyone needs to feel appreciated. It doesn’t matter what they do, it doesn’t matter who they are, that’s a need in everybody.

– Grace McNiel (Hugh Jackman’s mom)

Hugh Jackman mentioned this quote on a podcast with Tim Ferriss. Highly recommend listening to the podcast. Hugh shared a lot more such wisdom in it. My admiration for Hugh went up a couple more notches after listening to it.

Collection of tools to serve local content on your workstation to the Internet

A quick collection of tools you can use to serve/publish content/applications on your local dev to the Interwebs. Some use cases for these types of tools..

  • Developed a static website and want to show it someone that is not right next to you.
  • Developed an API that you want an app or user to access from the web

List of tools:

  • https://ngrok.com/ : Most popular tool for this purpose. the free tier is enough for most use cases.
  • https://tunnelto.dev/ : Latest entrant in this space. In addition to have a paid hosted service, you can run this for free on your own server. But that defeats the pupose of having a tool to use in a pinch to share content :).
  • http://pagekite.net/ : Been around for 10+ years. Similar to tunnelto.dev, you can run this on you own server or pay (very nominal price) for the hosted service.

Fatherhood..

Today being Father’s day, some reflections on fatherhood. I think people go through different stages on how they view their dad.

Admiration ( 0 – teen years) : Your dad is a superhero. He can lift you up (just imagine another human being able to lift you up, throw you in the air and then catch you safely :-).. mindblowing!!). He can apparently conjure ice cream at will. You feel safe in his embrace. He is superman!

Respect (teen – having a kid of their own) : By the time you are in your teens, you are probably stronger than your dad :). Your admiration turns to respect. Your dad is the guy that is always their despite not getting anything in return.

Love (After having kids of their own) : You understand what it means to be responsible for another human being!! All that admiration and respect turns to love ❤️
