Imagine using Python's IDLE interface to edit text. You would be able to load files into memory, edit them, and save changes. But every action you perform would be defined by a Python function. Making a word all capitals, for instance, calls upper(), opening a file calls open, and so on. Everything in your text document is a Python object and can be manipulated accordingly. From the user's perspective, it's the same experience as any text editor. read more

Something that is definitely very true today, and it was also true in 2013, is that developers want to work with open source tools. The tools developers choose to build their applications with are essentially how they're building their career. Those tools are going to be line items in their resume that says, I know this technology, I can build with these tools. So realistically, they want to adopt open source because they can take that from job to job, company to company and from cloud provider to cloud provider.

React.js and React Native are popular open source platforms for developing user interfaces (UIs); both rank well for desirability and use in StackOverflow's 2019 Developer Survey. React.js was developed by Facebook in 2011 as a JavaScript library to address the need for cross-platform, dynamic, and high-performing UIs, while React Native, which Facebook released in 2015, is used for building native applications using JavaScript.

In the UTF-8 files I audit, the only invisible characters I expect to see... er... not see... are whitespace, horizontal tab and linefeed. All others I call "gremlins". They include carriage return, no-break space, soft hyphen and another 62 control characters. Gremlins are a nuisance. One gremlin causes a shell to hang. Less evil gremlins lurk inside apparently OK strings and cause the strings to be processed weirdly. This post explains a new script that locates and visualises gremlins in tab-separated tables.

This is what is responsible for providing abstractions for the battery, charging system, keyboard, touchpad, suspend/resume, and thermal control, among others.

I recently read a survey on StackOverflow that said more than 49% of developers use Node.js for their projects. This came as no surprise to me. As an avid user of technology, I think it's safe to say that the introduction of Node.js led to a new era of software development. It is now one of the most preferred technologies for software development, right next to JavaScript.
