spotmarket PrototypingPosted: 2016-01-17
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)
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.
