You are browsing a read-only backup copy of Wikitech. The primary site can be found at wikitech.wikimedia.org
You will need lots of accounts, memberships and other secret keys to become a real productive member of the Analytics team. Here's an overview of things you should do in the first week. Please update this document as you go along!
Once you have a wikimedia e-mail address you should subscribe yourself to two e-mail lists:
Most of our communication happens on IRC, you should set up an IRC nick
- Install an IRC client -- ask team members for recommendations ( some would be quassel, irssi, pidgin, xchat, textual or adium if you're on a Mac )
- Follow instructions on https://meta.wikimedia.org/wiki/IRC/Cloaks to request an IRC cloack
- Connect to #wikimedia-analytics on Freenode
- Other channels you might be interested in:
#wikimedia-labs, #wikimedia-operations, #wikimedia-office
Make sure you have an employee account and that you can use the office wiki, your office wiki user will be given to you once you get your wikimedia e-mail address.
Please buy a high-quality headset -- your colleagues will love you for this. For more tips see https://office.wikimedia.org/wiki/Office_IT/Projects/Telepresence
We are part of a movement with a unique culture. It's worth taking the time to read a bit about how our biggest project works. This policy could be a useful start, as it introduces the core concepts from a concrete point of view: https://en.wikipedia.org/wiki/Wikipedia:Biographies_of_living_persons
The very first thing to do will be to get a labs/Wikitech (they are the same thing) account and a Phabricator account so you can file a task like https://phabricator.wikimedia.org/T96053 (likely somebody else will do it for you).
Please follow the next subsections (order matters!).
Labs is a cluster of virtual machines. Access is completely decouple from production and different ssh keys should be used.
Labs is not production but we have several tools hosted on the cluster, accessing to labs requires a wikitech account:
- Create account: https://wikitech.wikimedia.org/w/index.php?title=Special:UserLogin&type=signup&returnto=Main+Page
- Request Shell Access: https://wikitech.wikimedia.org/wiki/Help:Access
- Log in
- You need to set up ssh keys: []
- Upload your public SSH key: https://wikitech.wikimedia.org/wiki/Special:Preferences#mw-prefsection-openstack
- Please have in mind that labs is a testing environment thus this ssh key should only be used in testing, if you need access to machines in the production cluster your ssh key should be different.
- Configure your ~/.ssh/config with bastion hosts
- Get familiar with the labs environment, how to use the labs interface to spin up nodes, remove nodes, etc
https://phabricator.wikimedia.org is the version of Phabricator that we use. Follow https://www.mediawiki.org/wiki/Phabricator/Help#Creating_your_account_and_notifications to log in for the first time (please use the sunflower icon as suggested by the tutorial to leverage the single sign on).
- Create account: https://www.mediawiki.org/w/index.php?title=Special:UserLogin&returnto=Analytics&type=signup
- Log in
- Gerrit is the code review workflow we use, build on top of git
- Log in to Gerrit using your Wikitech/Labs credentials.
- To verify everything works, clone a repo repo from https://gerrit.wikimedia.org/r/#/admin/projects/?filter=analytics using SSH.
- Take a look at how to deal with gerrit in different work scenarios: http://etherpad.wikimedia.org/p/analytics-gerrit
Reading mailing lists is important. All projects we build or use are open-source, and as most open-source projects, they have communities which come together on mailing lists. There is much knowledge to be gained in these mailing lists.
- Please subscribe to:
- Please request acces to:
For an overview of all available mailing lists see https://lists.wikimedia.org/mailman/listinfo
- Optionally you may want to read archives or subscribe to the following mailing lists:
If there are mailing lists you want to read without subscribing you may consider using the following gateways:
Accessing production infrastructure
All Analytics team-members should have access requested to the following machines:
- Hadoop cluster
- Eventlogging DB through 1003, which means you are in analytics research group
Shell access to wikimedia cluster and production infrastructure
- Tickets are filed for the ops team to see and need to be approved by a manger: 
Talk with Andrew Otto about how to submit your private key. You would likely need to proxy your ssh connection from a know machine to access
some of the hosts above. You should not use the same ssh key for labs (testing) and stat1 machines (production).
The easiest would be to ask some team member for its .ssh/config file and get the proxy setup.
Please have in mind that different processes are required to access production machines (stat1) and testing machines (labs)
Sample ssh config
Sample ssh config:
### Short names Host <some host you want your system to auto-complete> ## Use bastion-eqiad.wmflabs.org as proxy to labs Host bastlabs HostName bastion-eqiad.wmflabs.org User <your-username> Host *.eqiad.wmflabs !bastion-eqiad.wmflabs.org User <your-username> IdentityFile ~/.ssh/id_rsa ProxyCommand ssh -a -W %h:%p bastlabs ## Prod Host bastprod HostName bast1001.wikimedia.org User <your-username> Host *.eqiad.wmnet *.wikimedia.org !bast1001.wikimedia.org User <your-username> IdentityFile ~/.ssh/id_rsa_prod ProxyCommand ssh -a -W %h:%p bastprod
- Add the Analytics Team Calendar to your default view. Someone (we all can manage sharing) should go to https://calendar.google.org and add you:
- My Calendars -> Settings
- Click Team Analytics -> Share This Calendar
- Add the new person
As far as equipment goes you will need a good development machine.
Minimum machine specs:
- >=4GB RAM
- i7 >= 2.4 Ghz quad-core or better
- 300GB disk
Recommended machine specs:
- >=8GB RAM
- i7 >= 2.4 Ghz quad-core or better
- SSD (if you're going to be working on wikimetrics)
- 300GB disk
At first sight you might think these are not required, but you will have to run VMs, you will be using vagrant to re-create various environments(sometimes with multiple nodes), so you will need some hardware for that.
You could consider creating accounts for:
The machines we deploy on are using Ubuntu and it would be more convenient for you to have Ubuntu installed on your development machine or any other UNIX based operating system. It will considerably facilitate your work. You may choose any other Linux distribution you're familiar with.
Mac is also a very possible choice.
This is a collection of things you might find useful in your work.
You may find the following tools useful for sync-ing files between your local machine and remote machines(one-way or two-way). You can also mount remote directories as if they were your local directories:
IDEs and editors
For Java development, you may use what IDE you feel comfortable with. Eclipse is the IDE du jour, but you might want to look at IDEA also. For remote development you may find vim to be useful(or a combination of a sync tool and your favorite editor/IDE). Other editors you might find useful may include Sublime Text, Emacs.
You may find the following tools useful to search through configuration files or code:
It may be useful that you familiarize yourself with Vagrant and Puppet to be able to recreate smaller environments/conditions on your machine to test various software you're developing or contributing to.
