What other Stack Exchange sites are there that may be able to answer my questions about software engineering or software development?

18

The following sites may be of interest to members of the Software Engineering community.

Before posting, be sure to read their Help Centers to fully understand what these communities expect from high quality questions and any specific rules they may have. As always, if you aren't sure if your question is a good fit, post on a Meta site and you can be directed to an appropriate site on the Stack Exchange network, if one exists.

If a site doesn't exist yet, check out Area 51, where users can collaborate to define and launch new Stack Exchange sites. If there's a proposal for your idea, you can follow it and contribute to it's definition. If not, you can create a new proposal.

More detailed information about each site follows:

Code Review

Code Review Stack Exchange is a question and answer site for seeking peer review of your code. We're working together to improve the skills of programmers worldwide by taking working code and making it better.

If you are looking for feedback on a specific working piece of code from your project in the following areas…

  • Best practices and design pattern usage
  • Security issues
  • Performance
  • Correctness in unanticipated cases

then you are in the right place!

Computational Science

Computational Science Stack Exchange is for questions and answers about computational methods used in technical disciplines.

First-time posters are strongly advised to read Eric Raymond's How to Ask Questions the Smart Way for advice on how to ask good questions (not for technical answers). Although written for an audience asking questions about open source software, the same advice applies when asking questions about any subject area.

This site is run by volunteers; the best way to get an answer to your question is to ask it in a way that makes it easy for someone with a broad computational science background to answer it with 15 minutes of effort or less.

Topics that are usually a good fit for this site:

  • Questions about software packages or languages used broadly in computational science (e.g., PETSc, MATLAB, Trilinos, LAPACK, SLEPc, R, NumPy, SciPy, Julia, Maple, Octave) except Mathematica (which has its own site now). In general, high-level questions (e.g., about language/package features) are best. Questions that are essentially about debugging a code sample, or about low-level language syntax are a poor fit for this site, and are usually closed; such questions should be asked on language-/package-specific forums. Package developers interested in using this site as a resource should look at this meta question. Package developers answering questions should look at this meta question for guidelines on disclosing project affiliations.
  • Questions about algorithms or methods used to solve problems in applied mathematics (e.g., finding roots of a polynomial, finding the eigenvalues/eigenvectors of a matrix, solving an elliptic/parabolic/hyperbolic PDE)
  • Questions that ask about appropriate methods for a given application area (e.g., what numerical methods would I use when modeling shock waves, what numerical methods would I use when modeling combustion, what graph algorithms would I use if I wanted to understand social networks)

Computer Science

Computer Science Stack Exchange is for students, researchers and practitioners of computer science.

Computer science, also sometimes called computing science, is the science of computation and its applications. This site covers theoretical and applied computer science at any level, including but not limited to:

  • hardware that has a paid support option (enterprise/provider class products, some small business class devices);

then this is likely the correct place to ask unless it meets any of the off-topic conditions detailed below.

Open Source

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

Software Recommendations

This site is for questions asking for recommendations of software ready-to-use to accomplish a particular task, that is, “what software can I use to do …?”. While this includes software libraries for development use, note that recommendations of tutorials, data sources, media libraries (e.g. icon collections) etc. are off-topic – as are questions like “what technology to use for …?”

Good software recommendation requests have two components:

  • A purpose — a task to accomplish, a user story
  • Some objective requirements — a minimum set of features

Stack Overflow

Stack Overflow is for professional and enthusiast programmers, people who write code because they love it. We feel the best Stack Overflow questions have a bit of source code in them, but if your question generally covers…

a specific programming problem, or a software algorithm, or software tools commonly used by programmers; and is a practical, answerable problem that is unique to software development

… 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 …
