Simple Django applications for writing Facebook applications and authentication

Creating Facebook applications or integrating websites with Facebook isn't complex or very time consuming. In case of Django there is for example very big django-facebook package that provides a lot of Facebook related features., a company I work with released a set of small applications that were used internally to make Facebook applications as well as Facebook authentication integrations. In this article I'll showcase those applications.

Astrophotography on a Teclast X80h tablet running Windows 8.1 on a classical x86_64 Intel CPU

Tablets based on x86_64 Intel CPUs and running Windows 8 are quite interesting group of devices. They aren't as popular as iPads or Android devices, they don't have as many apps, but they can run any app you can run on PC/Laptop with the same MS Windows. This can allow some mobile use of some hardware that uses Windows software. For example astrophotography is very Windows oriented so making Windows mobile could allow mobile astrophotography.

I've decided to test a cheap Chinese Teclast X80h tablet for use in astrophotography.

Example Ember.js + Django + Django Rest Framework single-page application

Ember.js is one of JavaScript frameworks for creating interactive single page web applications. Pages may change but the browser doesn't reload the page. This framework has some similarities with Django and can be good pick to start with such frontend applications for Django developers with some JavaScript knowledge.

In this article I'll show you an example Django + Django Rest Framework + Ember.js application. Classical posts and categories done in Ember and in Django for comparison.

A quick introduction to Docker containers for Django web developers

Docker is a platform for running applications in isolation. Using Linux containers makes the software layer isolated from the base system. The overhead needed for hardware virtualization used by for example Virtualbox is removed. Docker can help in development and deployment of web based applications and services - let us see how and when.

How cool is Lenovo Flex 10 netbook and how to install Linux on 32-bit UEFI system?

The launch of Intel Bay Trail CPUs refreshed the netbook market with small and portable netbooks and convertible devices that offer quite decent amount of performance and new capabilities due to detachable or flippable screen. The only thing Bay Trails lack when compared to ultrabook processors is better GPU.

In this article I'll review a Bay Trail representative, Lenovo IdeaPad Flex 10 and I'll show you how to install (a bit painfully) Linux on it - which requires fighting with unsupported 32-bit UEFI.

Get IMX174 and make it cheaper as a IMX249

IMX174 cameras offer low noise, vertical lines free images at very high framerates with global shutter. Point Grey or Basler cameras with those sensors are now in use mostly for solar imaging, but some also use it on planets. High quality and performance comes at a cost. Grasshopper 3 camera with IMX174 costs around $1300 which is around 4 times the price of cameras like ASI120MM, QHY5L-II or PGR Blackfly similar cameras.

Sony announced a new sensor IMX249, which also showed up on Point Grey Blackfly camera list. Instead of 162 FPS there is up to 41 FPS, but the price may be even less than half of the Grasshopper 3 price. Sensor performance is expected to be very similar to IMX174.
