Cheat sheet for Java syntax

Tue, 12/03/2019 - 16:02

Java is an open source programming language specifically designed to create universal applications that run on any operating system, open source or otherwise. It achieves this apparent magic by using a runtime specific to each OS. This runtime interprets the Java code so that the application runs as expected. It's an effective method that enables programmers to write their code once but deliver it to all computers that run Java (Linux, BSD, Windows, and Mac, to name the common ones).

Tue, 12/03/2019 - 16:00

Customer empowerment is one consequence of digital transformation. And as we explained in the first part of this series, it's a powerful one. Empowering customers can deepen their relationship with your organization—but it won't work if they don't trust you.

In this article, we'll explain how acting openly can create that foundation of trust—and why it can lead to business success.

Use the Window Maker desktop on Linux

Mon, 12/02/2019 - 16:00

Before Mac OS X, there was a quirky closed-source Unix system called NeXTSTEP. Sun Microsystems later made NeXTSTEP's underpinnings an open specification, which enabled other projects to create free and open source versions of many NeXT libraries and components. GNUStep implemented the bulk of NeXTSTEP's libraries, and Window Maker implemented its desktop environment.

My Linux story: Covering open source in Spanish

Fri, 11/29/2019 - 16:00

From time to time, when I'm looking for some help on how to do something on my GNU/Linux desktop or server, I'll come across an article or conversation in a language other than English. If that language happens to be French or Spanish, that's fine for me. If it's in Portuguese or Italian, I can stumble through it. And, for other languages, occasionally, I'll give one of those online AI translators a go in the hopes of gleaning something useful.

Monitoring Linux and Windows hosts with Glances

Thu, 11/28/2019 - 16:02

Sysadmins have many tools to view and manage running processes. For me, these primarily used to be top, atop, and htop. A few years ago, I found Glances, a tool that displays information that none of my other favorites do. All of these tools monitor CPU and memory usage, and most of them list information about running processes (at the very least).

How to bring more designers to open source

Thu, 11/28/2019 - 16:01

"Most designers don't have a clue about open source," says Eriol Fox of Ushahidi, a non-profit social enterprise that creates humanitarian, open source tech tools. Unfortunately, this means there are few design-related contributions to open source software, and this results in an abundance of poorly designed open source tools.

Modernize your Linux desktop with Enlightenment

Thu, 11/28/2019 - 16:00

One of Linux's many advantages is its ability to install and run on old computers. What Linux can't technically do is make an old computer's hardware magically perform better. After all, the hardware is the same hardware as ever, and sometimes old hardware feels notably slow when processing modern software that tries to take advantage of new hardware features.

Why do we contribute to open source software?

Wed, 11/27/2019 - 16:00

Organizations as a whole contribute to open source software projects for a variety of reasons.

One of the most important is that the open source development model is such an effective way to collaborate with other companies on projects of mutual interest. But they also want to better understand the technologies they use. They also want to influence direction.

The specific rationale will vary by organization but it usually boils down to the simple fact that working in open source benefits their business.

Make Lua development easy with Luarocks

Tue, 11/26/2019 - 16:02

Bash too basic? Too much whitespace in Python? Go too corporate?

You should try Lua, a lightweight, efficient, and embeddable scripting language supporting procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. And best of all, it uses explicit syntax for scoping!

Lua is also small. Lua's source code is just 24,000 lines of C, the Lua interpreter (on 64-bit Linux) built with all standard Lua libraries is 247K, and the Lua library is 421K.

A framework for building products from open source projects

Tue, 11/26/2019 - 16:00

My first memory of playing with a computer was through an MS-DOS terminal on the x86 PC in my grandfather's pharmaceutical research lab in the early '90s—playing games stored on 3.5" floppy disks and doing touch-typing exercises. As technology improved, I spent an obscene amount of time taking my computer apart to add more RAM, a new graphics card, or a new fan, mostly so I could play cooler games. It was a fun, ongoing project, and I bonded with my father over it. It was also way cheaper than buying a new computer.
