Freelancing

Freelancing Stack Exchange is for questions relating to self-employed and freelance workers.

If your question covers...

• Agency work while freelancing
• Selling services to different employers without a long-term contract with any of them
• Client responsibilities to freelancers
• Cross-border requirements and laws for freelancing

and isn't about...

• Working in a part-time or full-time setting for a company
• How to use features of a Freelancing website for finding work
• Asking for life experiences or opinions on freelancing
• Marketing or finding Freelancers within the site to complete your work

...then you’re in the right place to ask your question!

#Super User

Super User is for computer enthusiasts and power users. If you have a question about …

 

• computer hardware,
• computer software, or
• personal and home computer networking

 

and it is not about …

 

• programming and software development,
• video games or consoles,
• websites or web services like Facebook, Twitter, and WordPress,
• electronic devices, media players, cell phones or smart phones, except insofar as they interface with your computer,
• issues specific to corporate IT support and networks,
• asking for a product, service or learning material recommendation,

Unix and Linux Stack Exchange is for users of Linux, FreeBSD and other Un*x-like operating systems.

 

If your question is about:

 

• Using or administering a *nix desktop or server
• The Unix foundation underlying OS X (but generally not frontend application questions)
• The underlying *nix OS on an embedded system or handheld device (e.g. an Android phone)
• Shell scripting
• Applications packaged in *nix distributions (note: being cross-platform does not disqualify)
• UNIX C API and System Interfaces ( within reason )

If your question is a programming question, requiring knowledge of programming languages other than unix shell scripting languages, ask on Stack Overflow.

 

Please note that requests for learning materials (tutorials, how-tos etc.) are off topic. The only exception is questions about where to find official documentation (e.g. POSIX specifications).

Open Source Stack Exchange is a question & answer site about a group of related movements which encourage people to give up some of the rights given to them by copyright law, by using licenses which give others the freedom to use and transform their creative works, and which optionally (by using copyleft/share-alike licenses) ensure that these works will always be made available with the same rights. This site is not limited to software, but also covers art, literature, hardware, databases and more.

These movements have been spearheaded by a group of organisations: FSF, OSI, Creative Commons, Free Culture. These organisations prefer a variety of different terms (free, open source, libre) and sometimes define them with slight differences. But on this site these terms should in general be considered to be synonymous, except for questions which ask directly about their differences.

You've come to the right place if you have questions about:

• the history and philosophies of the FSF, OSI, CC etc
• understanding, applying, and complying with Free & Open licenses
• how communities collaborate together to produce, distribute, market and sometime monetize these projects
• what license to use for a specific situation - but please read How do I ask for a license recommendation? first

Personal Productivity

Personal Productivity Stack Exchange is for people wanting to improve their personal productivity. If you have a question about...

• achieving a productivity workflow, using techniques like GTD, Covey, Pomodoro, etc.
• fighting procrastination by getting energetic and motivated workflow
• ergonomics
• effective sleep habits and the entire sleep-wake transition
• learning, memory and creativity
