Seach public pics on flicker

While blogging, I keep needing images that I can use. Though I have no issue using proprietary one from google, however it would be best if I could put flickr to some use and develop an app that searches the and returns me images of my choice. It's jquery and JSOn that I have used. Thanks google!

here is the code

<!DOCTYPE html>
<style>img{ height: 100px; width: 100px; margin: 5px 5px 5px 5px; float: left; border: solid black}</style>
<script src=""></script>
function fetchJSON() {
var tag = document.getElementById('input');
// document.getElementByID("input");
     tags: tag.value,
     tagmode: "any",
     format: "json"
   },function(data) {
   $.each(data.items, function(i,item){
       $('#images').append('<a href="''"><img src="''"></a>val='+i+'');
       //if ( i == 20 ) return false;
//if ( i == 19 ) fetchJSON();

<input type="text" id='input'>
<input type="submit" value="GO" onclick="javascript:fetchJSON()">

<div id="images"></div>

TODO : simple UI tricks.
1. turn off the GO button once it is hit
2. make something like with flickr images

Capture and compare stdout in python unit tests

A recent fan of TDD, I set out to write tests for whatever comes my way. And there was one feature where the code would print messages to the console. Now - I had tests written for the API but I could not get my head around ways to capture these messages in my unittests.
After some searching and some stroke of genius, here's how I accomplished capturing stdout.

The economics of crypto investing

If you believe in the greater fool theory, there is no other market as speculative and volatile as the crypto market today. We are perhaps living in the biggest bubble of our times. I am not bullish on this market in particular. I am bullish on the mania. 90% of the cryptos we see today will crash. They are just tokens with no tangible value generation capability. However, I believe that the mania and euphoria will stay.

Having said that, should one consider investing in this market? Certainly!
The risk/reward is lovely, potential upsides and margins are huge and with 3-5% of your net worth, the bet on the mania is worth it.

How does one choose where to invest?

If you follow the stock markets, you are expected to do thorough Fundamental Analysis before investing. Expect the same for the crypto market. I invest in large caps. I invest in index funds. And I invest over and over again. Markets rise, always. Extrapolating the same strategy - invest in indices - the top 10 tokens by perfo…

Learn frontend to get good at backend : lessons for my 20 year old self

Only when you are the consumers of your own products, can you design the best ones! Same philosophies go for API design and programming in general.

This advice may seem counter-intuitive at first, but trust me, the best way to get better at backend programming is to spend some time doing frontend! It will teach you a lot about how your APIs are being used in the "real world". A first-hand experience of API consumption will tell you a lot about your design philosophies!
