Hockey-Info Release v1.0

https://gitlab.com/dword4/hockey-info

This is probably as “complete” as the Hockey-Info project may ever get so I figured its worth an actual blog post (and git tag at v1.0 too). A little over a year ago I was fed up with the NHL’s mobile website and decided I wanted to create something that gave me all the information without the associated fluff and annoyance. I had already spent time documenting the NHL API and using that knowledge to build smaller things like a sopel plugin for hockey stats. So I started throwing things together with Flask and suddenly hockey-info.online came to be!

Features

  • News Headlines
  • Scores view (only shows today’s games/scores)
  • Standings (grouped by Conference/Division and sometimes showing Wildcards)
  • Schedule (day, week and month views, team specific or league wide)
  • Team Views
    • Regular Season
    • Playoffs
    • Previous Games
  • Game details
    • Box Score information
    • Goals by period with details
    • Shots on goal by period
    • Penalties by period with details

Important Details

Built in Python 3 with Flask, Requests, and some various other bits and bobs. It runs either by itself with the usual process to launch a Flask application or if you are so inclined there is a Dockerfile that can be used to launch it with a little less pain.

There is some caching going on with requests_cache however this is by no means optimal, I would like to eventually do more work with a proper web cache but for now this works since the site is so light weight. I make use of CDNs for all the JavaScript so that also helps speed things up (and more importantly move the burden off of wherever you choose to run it in the first place).

Timezone awareness is non-existent, I basically converted everything from whatever the NHL stores (UTC time/date) to Eastern Time since that is where I live. I try to be very privacy conscious and I couldn’t justify the time expenditure in methods of determining user location for time conversion processes, if someone wants to suggest it or contribute it PRs are welcome.

Legal Considerations

I have zero affiliation with the NHL beyond sometimes buying their branded merchandise and viewing their games when I get the chance. There are no ads served by the application (or even any decent way to add them without altering all the templates) so I make no money from anything (not even the blog).

Quick Code: Repo List

So I ran into an interesting problem over the weekend, I forgot my 2FA token for Gitlab at home while I was away. My laptop’s SSH key was already loaded into Gitlab so I knew I could clone any of my repositories if only I could remember the exact name. That of course turned out to be the problem: I couldn’t remember the name of a specific repository that I wanted to work on. I even tried throwing a bunch of things at git clone to try to guess it and still had no luck. Enter the Gitlab API:

#!/usr/bin/env python3
                                                                                                                    import requests                                                                                                     from tabulate import tabulate
                                                                                                                    personal_token = 'asdfqwerzxcv1234'                                                                             user_id = 'dword4'                                                                                                                                                                                                                      base_url = 'https://gitlab.com/api/v4/'                                                                             repo_url = 'users/'+user_id+'/projects'                                                                                                                                                                                                 full_url = base_url + repo_url + '?private_token=' + personal_token                                                                                                                                                                     res = requests.get(full_url).json()
table = []
for project in res:                                                                                                     name = project['name']
    name_spaced = project['name_with_namespace']
    path = project['path']
    path_spaced = project['path_with_namespace']
    if project['description'] is None:                                                                                      description = ''                                                                                                else:                                                                                                                   description = project['description']                                                                            #print(name,'|', description)                                                                                       table.append([name, description])                                                                                                                                                                                                   print(tabulate(table, headers=["name","description"]))

This is of course super simplistic and does virtually no error checking, fancy formatting, etc. However now with a quick alias I can get a list of my repositories even when I do flake out and forget my token at home.

Simple CI with Chef

So I needed to work out a way to make a script I wrote recently be deployed across a whole host of systems, turns out the only option is Chef so I had to dive into it and read a bunch of stuff.  Also had to try a bunch of things and ended up with my own Chef server in the lab to test against.  Several hours of clicking and clacking later and I have my task worked out, so here it is.

First we need to create a new cookbook and drop a pretty simple default recipe in, all it does is make sure git is installed then clone a repo to /opt/nhlapi.

#
# Cookbook:: repo
# Recipe:: default
#
# Copyright:: 2018, The Authors, All Rights Reserved.
#
#
package 'git' do
  action :install
end

git '/opt/nhlapi' do
  repository 'git://gitlab.com/dword4/nhlapi.git'
  revision 'master'
  action :sync
end
default.rb (END)

Once we have the recipe we need a role to tell it what to do.

{
   "name": "repo-update",
   "description": "update chef from time to time",
   "json_class": "Chef::Role",
   "default_attributes": {
     "chef_client": {
       "interval": 1800,
       "splay": 60
     }
   },
   "override_attributes": {
   },
   "chef_type": "role",
   "run_list": ["recipe[chef-client::default]",
                "recipe[chef-client::delete_validation]"
   ],
   "env_run_lists": {
   }
}

Create the role with # knife role from file repo-update.json  (or whatever you named the file to create the role from).

Now all that is left is to assign the role to the node so use #knife node edit itsj-cheftest.itscum.local  and assign the role and repo to the node we want

{
  "name": "itsj-cheftest.itscum.local",
  "chef_environment": "_default",
  "normal": {
    "tags": [

    ]
  },
  "policy_name": null,
  "policy_group": null,
  "run_list": [
    "recipe[nginx]",
    "recipe[repo]",
    "role[repo-update]"
]

}

That is enough to get it working, you can kick back and watch it with # while :; do knife status ‘role:repo-update’ –run-list; sleep 120; done and wait to see it run in about 30 minutes based on the interval and splay values.  Speaking of which Interval is pretty self explanatory, but Splay not-so-much; Splay is used keep a bunch of nodes from all running at once basically so it doesn’t overwhelm a system that they might be checking into or otherwise digitally assaulting.
