BSD, C, httpd, SQLite.

BCHS is an open source software stack for web applications. To
prepare a BCHS environment, install OpenBSD, start your editor of
choice, and get to work.

How does a BCHS system look? See a trivial example.

Stack components

why bchs? because the open internet is inhospitable.

BSD

OpenBSD. World-renowned for its focus on security and documentation.
Reliable six-month releases. Binary patching. It takes the guess-work
out of your environment.

Resources: man pages, FAQ, Absolute OpenBSD, mailing lists.

the C Programming Language

C is a straightforward, non-mustachioed language. It has full access
to the kernel's system calls and a massive set of development tools
and libraries.

Resources: The C Programming Language, clang(1), clang-local(1).

#include <stdio.h>
int
main(int argc, char *argv[])
{
   puts("Hello, world!");
   return 0;
}

httpd(8)

OpenBSD's home-grown web server. If you need more features for your
web application, submit a patch.

Resources: httpd(8), httpd.conf(5), slowcgi(8), Relayd and Httpd
Mastery.

SQLite

SQLite is a `self-contained, embeddable, zero-configuration'
database. It's a practical solution for the majority of database
needs. Just pkg_add sqlite3 and you're ready.

Resources: API reference, SQL reference, The Definitive Guide to
SQLite.

BCHS is a stable, developer-oriented platform.

Get used to minimalism and security: componentised,
privilege-separated binaries in file-system jails. Most of all,
forget your instincts to search Google and StackExchange for every
parameter and function call: man pages are your new best friend.

FAQ

questions from the internet.

Is BCHS a joke?
    Software development is full of jokes. This is not one of them.
How do I pronounce `BCHS'?
    It's pronounced /bi:tS@z/, beaches. Or just Bee See Haich (or
    `Aich') Ess.
How can I hire BCHS developers?
    OpenBSD developers maintain an extensive list of support options,
    but these mostly relate to system administration. A better option
    is to contact your local user group; or if an event is upcoming,
    attend and make enquiries in person. Falling through these
    options, polite enquiry on OpenBSD's misc mailing list might get
    you pushed in the right direction.
Wasn't this site once funnier?
    Yes. But some folks confused humour with levity.
