  Unicode over 60 percent of the web

Computers store every piece of text using a “character encoding,” which gives a number to each character. For example, the byte 61 stands for ‘a’ and 62 stands for ‘b’ in the ASCII encoding, which was launched in 1963. Before the web, computer systems were siloed, and there were hundreds of different encodings. Depending on the encoding, C1 could mean any of ¡, Ё, Ä„, Ħ, ‘, ”, or parts of thousands of characters, from æ to å...

  On Employers, Portfolios, Commitment, and Cake

You might know from experience that planning for a wedding is no simple feat. In the months leading up to our wedding, my then fiancé and I spent countless hours planning and making sure that no detail was overlooked. Among our top priorities was finding a skilled baker to create a delicious and beautiful cake. On the recommendation of a friend, we considered a baker named Jennifer. We read her "culinary resume."

  Thoughts on Running an Open Source Project

I spoke in the unconference at PHPUK last week, on running an open source project. I thought I would collect together my thoughts into one place before I lose the scratty piece of paper I wrote them down on. I'm not sure I'm the right person to be giving advice exactly, but these are the things that, having been project lead on joind.in for a while, I think are important. Community I love it when people share their code, just make something and publish it, but to my mind it isn't an open...

  Investment Banking in China — What I’ve Learned & Unlearned

Anyone seeking to succeed in investment banking in China should live by one rule alone: it’s not who you know, but how well you know them. In China, more than any other country where I’ve worked, the professional is also the personal. Comradeship, if not friendship, is always a necessary precondition to doing business together. If you haven’t shared a meal – and more importantly, shared a few hundred laughs – you will never share a business deal. Competence, ex...

  Remove duplicated elements in JavaScript array

During interviews, one frequent question asked would be something like how to remove duplicated elements in a JavaScript array and how many different ways you can think of. The interviewee would also be asked to write the code down. In real applications, normally front end would not need to handle this case since normally it would be done by backend, but still it's necessary for front end developers to know different ways of doing this. This post will share some of the common ways to remove dupl...

  Top 5 Reasons Not to Use Hadoop for Analytics

As a former diehard fan of Hadoop, I LOVED the fact that you can work on up to Petabytes of data.  I loved the ability to scale to thousands of nodes to process a large computation job.  I loved the ability to store and load data in a very flexible format.  In many ways, I loved Hadoop, until I tried to deploy it for analytics.   That’s when I became disillusioned with Hadoop (it just "ain't all that"). At Quantivo, we’ve explored many ways to deploy H...
