The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

Update HISTORY.md
Commit the changes:

git add HISTORY.md
git commit -m "Changelog for upcoming release 0.1.1."

Update version number (can also be minor or major)

bumpversion patch

Convert shapefile to geojson, s_srs defines the input projection, t_srs defines the output projection to the EPSG code 4326 (http://spatialreference.org/ref/epsg/4326/) see also http://www.gdal.org/ogr2ogr.html

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

Build a scalable Twitter clone with Django and GetStream.io

In this tutorial we are going to build a Twitter clone using Django and GetStream.io, a hosted API for newsfeed development.

We will show you how easy is to power your newsfeeds with GetStream.io. For brevity we leave out some basic Django-specific code and recommend you refer you to the Github project for the complete runnable source code. At the end of this tutorial we will have a Django app with a profile feed, a timeline feed, support for following users, hashtags and mentions.

I assume that you are familiar with Django. If you're new to Django the [official tutorial] (https://docs.djangoproject.com/en/2.0/intro/) explains it very well.

Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

Writing your own home-grown cryptography primitives (For example: Mifare Classic)
- Exception: For the sake of learning, but don't deploy it in production.
Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
Not using a cryptographically secure random number generator
