The Yocto Project is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded products regardless of the hardware architecture. It was founded in 2010 as a collaboration among many hardware manufacturers, open-source operating systems vendors, and electronics companies to bring some order to the chaos of embedded Linux development.

Tired of rejections? Cath Chapman and Tim Slade offer a simple way to fight back

All academics aim to publish in high impact journals. However, many leading scientific and medical journals reject more than 80% of the manuscripts they receive, making rejection the biggest barrier to publication in high quality journals. We propose a novel solution to this problem. It involves very little extra work by submitting authors, is applicable to a wide range of circumstances (such as flawed study, lack of broad interest to the field, or highly critical assessors), and is scalable to meet the needs of academics from various disciplines. To be submitted on receipt of a manuscript rejection, the rejection of rejection letter (box) aims to significantly improve the publication rates of participating academics by overcoming the leading barrier to publication—manuscript rejection. An electronic copy of the letter is available from the authors on request.

Mathomatic™ is a portable, command-line, educational CAS and calculator software, written entirely in the C programming language. It is Free and Open Source Software (FOSS), published under the GNU Lesser General Public License (LGPL version 2.1), and has been under continual development since 1986. The software can symbolically solve, simplify, combine, and compare algebraic equations, simultaneously performing generalized standard, complex number, modular, and polynomial arithmetic, as needed. It does some calculus and is very easy to compile/install, learn, and use.

We started this project because a growing number of people are using Haskell to solve everyday problems. Because Haskell has its roots in academia, few of the Haskell books that currently exist focus on the problems and techniques of everyday programming that we're interested in.

With this book, we want to show you how to use functional programming and Haskell to solve realistic problems. This is a hands-on book: every chapter contains dozens of code samples, and many contain complete applications. Here are a few examples of the libraries, techniques and tools that we'll show you how to develop.

percol is an interactive grep tool in your terminal. percol

• receives input lines from stdin or a file,
• lists up the input lines,
• waits for your input that filter/select the line(s),
• and finally outputs the selected line(s) to stdout.

Since percol just filters the input and output the result to stdout, it can be used in command-chains with | in your shell (UNIX philosophy!).

A long list of top python projects in 2014.

A collection of design patterns and idioms in Python.

“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.” – Brian W. Kernighan.

Everyone tests their software to some extent, if only by running it and trying it out (technically known as “smoke testing”). Most programmers do a certain amount of exploratory testing, which involves running through various functional paths in your code and seeing if they work.

Systematic testing, however, is a different matter. Systematic testing simply cannot be done properly without a certain (large!) amount of automation, because every change to the software means that the software needs to be tested all over again.

This is an introduction to some lower level automated testing concepts, and how to use built-in Python constructs to start writing tests.

Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate can be. Let’s Encrypt automates away the pain and lets site operators turn on and manage HTTPS with simple commands.

No validation emails, no complicated configuration editing, no expired certificates breaking your website. And of course, because Let’s Encrypt provides certificates for free, no need to arrange payment.
