  The trap of the performance sweet spot

This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types somet...

  Never create Ruby strings longer than 23 characters

Looking at things through a microscopesometimes leads to surprising discoveries Obviously this is an utterly preposterous statement: it’s hard to think of a more ridiculous and esoteric coding requirement. I can just imagine all sorts of amusing conversations with designers and business sponsors: “No… the size of this <input> field should be 23… 24 is just too long!” Or: “We need to explain to users that their subject lines should be les...

  Understand unsafe in GoLang

Before going to understand unsafe package in GoLang, the first thing needs to talk about is the pointer in GoLang. If you have a background of C language, you must know what pointer means and its usage. With pointer, you are free to operate any data at memory level which means you have great power, but this means that you have great responsibility as well. That's why it might be considered unsafe in lots of cases. Take a look at a simple example of doubling an integer. package main import "fmt"...

  Could coding be the next mass profession?

Like farming was in the 17th century, factory work during the industrial revolution, construction during the Great Depression, and manufacturing after World War II. Better, because writing code is a creative act which can be done with or without a traditional (antiquated?) office-based job, and can create enormous personal and economic value. Most young people start in jobs that don’t have much of a future. Most don’t get higher education – only a third get a...

  Making Your Tech Conference Presentation, and Experience, Not Suck

Tech conferences are incredibly expensive, and not just in dollars. Even free conferences like BarCamps incur the expense of the attendee’s time. Taking time off from work or family is a hassle at the very least, and it’s time that isn’t billable. The draw of the conference boils down to those 45 minute sessions, and speaker and attendee alike should make the most of it. Speakers often start off by wasting time. They front-load the presentation with worthless informatio...

  7 Resources Every JavaScript Developer Should Know
