comment Routing traffic using IP tables for two NICs
I'm voting to close this question as off-topic because it is lacking in research.

comment Is there a tool to browse a VMWare VMFS datastore hard drive on a PC?
Sure, but this answer hasn't evolved in three years...

comment Can you use configuration management (Puppet/Chef) behind a firewall?
I especially like Rundeck in general because you can use LDAP-auth, manage permissions on projects and jobs, and the http log gives you audit-trails of 'who did what, when'.

comment Can you use configuration management (Puppet/Chef) behind a firewall?
If you wanted to wrap things that you would otherwise use knife for in a tool, I would consider using Rundeck. You can also set a runlist and environment on a node as part of the chef-bootstrap.

comment When is it appropriate to use a configuration manager (eg Puppet / Chef / Ansible)?
Absolutely! Getting into Chef has been a huge career win for me. Here's the real thing: in a couple years CM will be just about required/expected for all but junior SysAd jobs.

comment How to figure out which RabbitMQ node was stopped last
Were this my problem to solve, I would have ship the 'nodes running at shutdown' value to Logstash, and send a binary value to graphite of whether RabbitMQ is running. Without those kinds of facilities, I don't know what I would do other than check that value on the cluster nodes.

comment Getting a list of all the snapshots in VMs managed by vCenter?
This is a great answer. I've gotten a lot of good use out of PowerCLI, but if Powershell isn't your thing, PowerCLI (and this answer in particular) is a great example of a vSphere API Client, so feel free to check out the vSphere API docs for your language of choice!

comment What is Windows equivalent to Puppet/chef?
Despite providing this answer, I strongly prefer Chef over Group Policy. If I really wanted to be twisted, I'd use GP to install Chef and nothing more.

comment Access to logs for not root/sudo user
To those things, I would suggest a separate deployment mechanism for the applications that you deploy, and configuration management to not only manage, but store a history of configuration changes. These allow your people to achieve the capabilities that they need to do their work, but also provides you layers of safety (in both access-control as well as auditing.)

comment Does the sAMAccountName rename practice based on employment status makes sense?
There are roughly a billion fields that could be used for holding auxiliary data. Not to mention having a "Temp_Employees" Group or setting an expiration date on the user account to match their contract end-date.

comment Go(lang) with nginx - Serving Static Files
I've been looking at go for all of two hours, but would it be helpful to use the concurrency and channels (prefix some of those with the 'go ' keyword) for parallelization?

I could also remark that I put in as much effort as you apparently did researching your question. "Ubuntu find what is installed" and "Ubuntu what processes are running" works in my version of Google...

The term for what you describe is "Developer" or "Developer forced to take on some Systems / Operations duties".

You are not a DevOps. DevOps is not a title, it's a culture.

comment How to use wrapper recipes in chef?
This is in a custom cookbook recipe, in this example, the cookbook is called 'appname'. Honestly, it sounds like you should spend some time on learnchef.opscode.com

comment Disk Capacity Planning for Whisper / Graphite
You have to calculate this for every retention policy, and 4.5MB is what it works out to for my (single) retention policy, but yes, that's the rough formula...

comment Disk Capacity Planning for Whisper / Graphite
This is a new implementation at this company, and I don't have access to my old one. Since the top-level fileSize result matches the ls -l result, I take that to be bytes. When I add up the sizes of the archives within the .wsp file (as reported by whisper-info.py), they come close to the overall .wsp file size (the rest I assume being metadata and such. This should be the size of the file for all time, as data falls down to lower data resolutions, and old data points are discarded.
