Building, packaging, and deploying Python using versioned artifacts in Debian packages. At Nylas, we’ve developed a better way to deploy Python code along with its dependencies, resulting in lightweight packages that can be easily installed, upgraded, or removed. And we’ve done it without transitioning our entire stack to a system like Docker, CoreOS, or fully-baked AMIs.

In Python code reviews I’ve seen over and over that it can be tough for developers to format their Python code in a consistent way: extra whitespace, irregular indentation, and other “sloppiness” then often leads to actual bugs in the program. Luckily automated tools can help with this common problem. Code linters make sure your Python code is always formatted consistently – and their benefits go way beyond that.

We asked Collier what it takes to code in Python for a major quant fund. – And whether learning how to code as a second career after trading is actually viable. This is what he said.

It's a free book available for download. This text summarises a number of core ideas relevant to Computational Engineering and Scientific Computing using Python. The emphasis is on introducing some basic Python (programming) concepts that are relevant for numerical algorithms. The later chapters touch upon numerical libraries such as `numpy` and `scipy` each of which deserves much more space than provided here. We aim to enable the reader to learn independently how to use other functionality of these libraries using the available documentation (online and through the packages itself).

Free networks often impose either a time or data restriction and this can be used quickly. When this happens you can change your mac address and reconnect, but this is annoying, and it takes time. In addition, most networks will ask you to re-accept the terms and conditions of the network in order to continue. Rollmac is designed to automate this process by using the WPAD protocol to discover the login page and automatically re-accept the terms and conditions.
