spotmarket on Github

initial commit

I published the initial code to GitHub with install directions for Ubuntu. The project so far is a Python script that consumes map API jump and kill activity and inserts them into a PostgreSQL database. Details as to why I picked these two items as starting points to come later.

So far this has been a fun learning project; I’m getting more familiar with Python datatypes/iterators/quirks, have been leveraging arrow for any datetime work, am getting more comfortable with pandas, and have a handle on the basic differences between MySQL and PostgreSQL.

Growing Laundry List

  • Frontend – The previous project was written in a PHP framework and I have some basic JavaScript under my belt, but I am historically more of a backend/server focused person so web presentation is a weakness of mine. Django has been mentioned to me so perhaps I will do some research.
  • Implement more efficient UPSERT to improve database insertion efficiency.
  • Figure out what CREST market data to record.
  • Start working on putting the pieces together for the first analysis — more on that later.

The past few months have been a series of shifting goals and commitments for me, both personally and professionally. I’ve spent more time outside running trails in the Marin Headlands and I changed jobs, landing a engineering role at a trading firm.

The winter months in San Francisco mean rain, and as such, I have been spending a lot of time reading Python tutorials, collaborating with James and Greg at element43, and working on a list of design requirements for the spotmarket trading platform.

The biggest addition to the project has been the buildout of a proper homelab server running ESXi. I’ve wanted to build out a homelab since I’m a network engineer and often tinker, but I’ve never really had a driver for the project. For the odd virtual machine or instance of a virtual switch/router that I’ve needed, I’ve leveraged an install of Oracle VirtualBox on my desktop. Now that I want to run development, production, and other testing machines, I built out a server.

Server ‘esx-01’, Uninspired Name

I ended up running ESXi 5.5 because I struggled to get my ‘unsupported’ NIC to work in 6.0. I followed a few guides to load drivers into the installation ISO, but was unable to get the setup procedure to complete properly for 6.0. My needs are basic on the VMware end so I’m sticking with 5.5 as I was able to get that to install with Realtek 8168 onboard NIC.

Details for the build:

  • ASUS M5A99FX PRO R2.0 Motherboard
  • AMD FX-8320 Vishera 8-Core 3.5 GHz CPU
  • SanDisk Ultra II 2.5″ 480GB SSD
  • G.SKILL Ripjaws X Series 16GB (2 x 8GB)

Python Learning

I was in a computer engineering program for two years in college before switching over and finishing in a telecommunications program. During that time I was exposed to assembly, C, and C++. I spent many late nights struggling with those languages, so I was apprehensive to dive back into programming.

I picked Python as the main language for this project and so far it has been outstanding. I’m getting more comfortable with the Python datatypes, iterators, and reliance on indentation. For data manipulation I’m using pandas, which for anyone that loves rows and columned data, it is second nature.

Another item that has taken a lot of brain time has been the switch from MySQL to PostgreSQL. I’ve had to learn about the use of schemas, differences in data types, how to enable TCP access, and migrate my administration/query generator tool over to pgAdmin.

The Chats

If you have any comments or want to chat with me, find me on the new #k192space channel at tweetfleet.slack.com. Upcoming posts will delve into coding and talk about the reporting that I’ve started to build.
