Redis based IP blacklist for Nginx (LUA)
-- a quick LUA access script for nginx to check IP addresses against an
-- `ip_blacklist` set in Redis, and if a match is found send a HTTP 403.
--
-- allows for a common blacklist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- block an ip:
-- redis-cli SADD ip_blacklist 10.1.1.1
-- remove an ip:

PHP Serialization Fix. For use after a find/replace/sed on MySQL dump, to repair String lengths in serialized PHP objects. Optimized and refactored for memory-safe production use in Python (~7s for 250MB dump, ~400K replacements). Written also in Perl (~7s for 250MB), Ruby (~8s for 250MB) and Go (~20s for 250MB) for benchmark comparison. Python …

Alternative ways to define react Components

The 0.13.0 improvements to React Components are often framed as "es6 classes" but being able to use the new class syntax isn't really the big change. The main thing of note in 0.13 is that React Components are no longer special objects that need to be created using a specific method (createClass()). One of the benefits of this change is that you can use the es6 class syntax, but also tons of other patterns work as well!

Below are a few examples creating React components that all work as expected using a bunch of JS object creation patterns (https://github.com/getify/You-Dont-Know-JS/blob/master/this%20&%20object%20prototypes/ch4.md#mixins). All of the examples are of stateful components, and so need to delegate to React.Component for setState(), but if you have stateless components each patterns tends to get even simpler. The one major caveat with react components is that you need to assign props and context to the component instance otherwise the component will be static. The reason is

from django.db import transaction
@transaction.atomic
def create_user_view(request):
if request.method == 'POST':
user_form = UserCreationForm(request.POST)
profile_form = ProfileForm(request.POST)
if user_form.is_valid() and profile_form.is_valid():
user = user_form.save()
user.refresh_from_db() # This will load the Profile created by the Signal

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
