  Why Memorizing is Ineffective

The information-age has burst into life, creating a wake of social change. Young people are growing up faster and more sophisticated, as raw information, tailored-entertainment, and branded-marketing are streamed into their rooms. But this technological exposure has not necessarily made them savvier or more capable of handling tomorrow’s challenges.The debates in public education over “school-choice” and standardized testing have missed the far more important issue. The real c...

  You know what UTF-8 is when you see it?

When we are coding we may often see some encoding specifications in our source codes such as UTF-8,GB2312. Do you know what these encoding mean and why we need them? In this post, Julián Solórzano will introduce the most widely used encoding specification around the world accomodating all different character sets in the world. UTF-8 is a method for encoding Unicode characters using 8-bit sequences. Unicode is a standard for representing a great variety of characters from many ...

  bash network interface

Some of us may have seen /dev/tcp/<host>/<port> before, is this a special file system implemented in some BSD kernel? Because there is no /dev/tcp in Linux. Actually, this one is implemented in bash. We no need to rely on wget,nc to do network connection. It's very easy to use this interface: bash-4.2$ cat </dev/tcp/time.nist.gov/13 56188 12-09-18 15:34:26 50 0 0 733.5 UTC(NIST) * bash-4.2$ exec 3<>/dev/tcp/www.w3.org/80 bash-4.2$ echo -e "GET / HTTP/1.0\n\n" >&3 b...

  Are frameworks making developers dumb?

Last week I got to take interviews to hire senior java developers with around 5 years of experience. But after the interview process is over I felt like the frameworks makes developers life easier but at the same time making them dumb.Everyone puts almost all the new frameworks on their resume claiming they have "Strong, working experience on Spring, Hibernate, Web Services etc".Here is how the interviews went on.Me: You have used Spring in your latest project. What are the advant...

  Bash Shell Scripting - 10 Seconds Guide

This Bash shell scripting guide is not a detailed study but a quick reference to the BASH syntax. So lets begin... Common environment variables PATH - Sets the search path for any executable command. Similar to the PATH variable in MSDOS. HOME - Home directory of the user. MAIL - Contains the path to the location where mail addressed to the user is stored. IFS - Contains a string of characters which are used as word seperators in the command line. The string normally consists of the spac...

  ECMAScript 6 looks promising

I am quite excited about ECMAScript 6, after watching David Herman’s talk at YUIConf 2011. I am especially looking forward to seeing some of these features landing up on V8 soon, so that I can use it on node.js. These additions will solve many common sources of frustration that newcomers face when working with JavaScript. Although the spec is not expected to be finalized till 2013 (so says David in the video), a lot of these features are expected to hit Chrome and Firefox much befor...

  Bionic Office

Well. That took rather longer than expected. We have, finally, moved, into the new Fog Creek office at 535 8th Avenue, officially ten months after I started pounding the pavement looking for a replacement for my grandmother's old brownstone where we spent our first few years, working from bedrooms and the garden. Most software managers know what good office space would be like, and they know they don't have it, and can't have it. Office space seems to be the one thing that nobody can get rig...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...

  A Month With Scala

Although I’ve played around with Scala for the few months, these efforts largely involved simple scripts and casual reading. It wasn’t until last month that the opportunity to use Scala in a large scale project finally arose and I dove right in. The project was a typical REST based web service built on top of Amazon’s Elastic Beanstalk, SimpleDB, S3 and Redis*. First off let’s talk about why I chose Scala in the first place. After spending a good deal of my las...

  Five-minute Multimethods in Python

So what are multimethods? I'll give you my own definition, as I've come to understand them: a function that has multiple versions, distinguished by the type of the arguments. (Some people go beyond this and also allow versions distinguished by the value of the arguments; I'm not addressing this here.) As a very simple example, let's suppose we have a function that we want to define for two ints, two floats, or two strings. Of course, we could define it as follows: def foo(a, b): if...
