Towards creating a decentralized and distributed web application using IPFS and Elm
Topics covered
* A little about IPFS and why its great
* Getting started with IPFS on WSL (Ubuntu Xenial on Windows)
* Getting started with Elm
* A simple example hosting a web application on IPFS
Why am I doing this?
The future of the internet is the distributed, decentralized web. This is a place . . .
Hashcash in F#
Implementing the hashcash algorithm in F#
Why am I doing this?
The hashcash algorithm forms this basis of cryptocurrencies like Bitcoin. I have been getting into this kind of technology, like the blockchain and cryptocurrency, lately (this is the future!) and I thought it would be fun to try to implement the hashcash algorithm in F#. Plus the proof-of-work system seems to . . .
Low-fuss database migrations
Migrate your database from source control at build time with TeamCity and SQL Compare
Why am I doing this?
At work, I have been working on getting our applications into the build pipeline (in TeamCity). I have been making good progress on the application side but a lot of our database migrations were still kind of manual. I would inevitably end up with a failing build because I forgot to open up SQLCompare, compare . . .
Deploy your Python code to AWS Lambda using the CLI
How to get started creating and deploying a Python package
Why am I doing this?
The AWS provided tutorials are too much stuff. Here I have simplified it. Plus I needed to deploy some code.
This is a continuation of my article on getting started with AWS Lambda.
What you will need
- the AWS CLI
- some Python code
- an AWS . . .
POSTing images to pure F# Web API 2.0
Getting the multi-part form data out of your web API requests
Why am I doing this?
I have a REST API that I built with the Pure F# Web API templates. Mostly my REST API was just designed to output and process JSON, but recently I needed to accept images.
The problem
I need to save some images, through my REST API, that are produced on another system. I need that system to . . .
AWS Lambda and S3: a quick and dirty tutorial
Figure out the basics without tearing your hair out
Why am I doing this?
I wanted to setup an example of how to use AWS Lambda with S3 for two reasons: do a talk on using these features at the Tucson Python Meetup (TuPLE), and help a a TuPLE member get started with a prototype for his (totally awesome) radiology image-processing functions.
BTW: this is a great reason to go . . .
A bit of Railway Oriented Programming with Coconut
Using Coconut/Python to build a pipeline with error handling
Why am I doing this?
I recently did a talk on Coconut at the Tucson Python Meetup (aka TuPLE). I mostly demoed the examples in the tutorial and the documentation, but I also came up with a way to do error handling like I do in F# with Railway Oriented Programming that I learned from F# for Fun and Profit.
