How to use interfaces in Go

Mon, 08 Oct 2012 10:20:57 +0600

How to use interfaces in Go:

jordanorelli:

Before I started programming Go, I was doing most of my work with Python. As a Python programmer, I found that learning to use interfaces in Go was extremely difficult. That is, the basics were easy, and I knew how to use the interfaces in the standard library, but it took some practice before I…

Fixie - Dynamically generated filler content

Thu, 14 Jun 2012 15:31:53 +0600

Fixie - Dynamically generated filler content:

thechangelog:

Ryhan Hassan has created a neat little JavaScript library that adds filler content to your HTML mockups. Using it is very simple, just add the fixie.js library to your HTML before the closing tag, and Fixie looks for anything with a class of fixie.
It’s smart enough to fill an
tag with a phrase, a
tag with a paragraph, an tag with an image, and so on. If you want to add fixie it to a container, it can handle that too!

By default, all images will be pulled from placehold.it, but changing that is very simple:
fixie.setImagePlaceholder('http://flickholdr.com/${w}/${h}/canon').init();
View the sample (refresh the page a few times to see the content generated dynamically) or browse the source at GitHub.

3 Key Software Principles You Must Understand

3 Key Software Principles You Must Understand:

If you’re in software development, new techniques, languages and concepts pop up all of the time. We all feel those nagging doubts every now and then: “can I keep up with the changes and stay competitive?” Take a moment, and sum a line from my favorite movie, Casablanca: “The fundamental things apply, as time goes by.”

Multiple Django and Flask Sites with Nginx and uWSGI Emperor

Thu, 17 May 2012 14:48:35 +0600

Multiple Django and Flask Sites with Nginx and uWSGI Emperor:

When you start uWSGI in Emperor mode, you give it a directory to watch that contains all of your uWSGI config files. If a new file is added, the emperor process reads it and spins up loyal worker processes to handle requests. If a config file is touched or modified, the emperor will gracefully restart the associated worker processes. And if a config file is removed, the emperor will kill the relevant workers.

Bootstrap-powered viewer makes RFCs easier on the eyes:

In what may be the most useful application of the Twitter UI framework, Mislav Marohnić offers RFC, a website that reformats The Internet Engineering Task Force (IETF) documents into something a bit more reader friendly:

I know which I’d rather read. The source is on GitHub and the live site is running on Heroku.

“To design is much more than simply to assemble, to order, or even to edit; it is to add value and meaning, to illuminate, to simplify, to clarify, to modify, to dignify, to dramatize, to persuade, and perhaps even to amuse.”

Scope and this in JavaScript

Thu, 26 Apr 2012 11:08:37 +0600

Scope and this in JavaScript:

Today I want to talk a little about scope in JavaScript and the this variable. The idea of “scope” is that it’s where certain functions or variables are accessible from in our code, & the context in which they exist & are executed in.

Using HTML5 localStorage on a form

Thu, 26 Apr 2012 10:14:57 +0600

Using HTML5 localStorage on a form:

HTML5 localStorage provides us with the ability to store named key/value pairs locally within a users browser, this means that the data stored in localStorage is still there even after a user has closed the browser, deleted their cookies or turned off their machine/device.

The HTML5 localStorage attribute is supported by most modern browsers including Firefox 3.5+, Chrome 4+, Safari 4+, Mobile Safari, Android 2+ and Internet Explorer 8+.

Now lets dive into some code and create a basic working example. In this example we are going to create a simple form which stores the data entered into the form so that if the form isn’t submitted but the browser is closed the data is still store and then retrieved when the user returns to the form.

Spawning in Unix:

I write a lot of low-level C code dealing with Unix processes and the like. I have seen a few folks roll their own spawn function, and do it wrong, so this page is meant to serve as an overview of your options when writing programs using only core Unix functions.

Rx: My prescription for your Go dependency headaches

Rx: My prescription for your Go dependency headaches:

There has been a lot of discussion on the Go Nuts mailing list about how to manage versioning in the nascent Go package ecosystem. We muttered about it at first, and then muttered about it some more when goinstall came about, and there has been a pretty significant uptick in discussion since the go tool began to take shape and the Go 1 release date approached. In talking with other Gophers at the GoSF meet-up recently, there doesn’t seem to be anyone who really has a good solution.

How to Improve Your Productivity Using Agile Techniques

How to Improve Your Productivity Using Agile Techniques:

Improved productivity is the goal of every freelancer.

Ever since I started my one-man business, I have looked for ways to improve my productivity and get things done faster. There were a couple of methods that seemed to lead to small improvements, but overall none of them proved efficient.

That is, until I discovered agile techniques. In this post, I’ll discuss some of the ways that agile techniques can help improve a freelancer’s productivity. Specifically, I’ll look at agile methods in general and at Scrum methodology.

/dev/notes: Mysqldump tables matching a pattern:

aaronbonner:

Yesterday on Twitter someone asked if there was a way to export data from mysql, but only from tables matching a like pattern. E.g. something like
mysqldump -uuser -p mydb mytables_*
There isn’t an inbuilt mechanism to do this, my reply was to use a shell script with an array containing a list…
