This is a simple request, but the official docs are out of date.
- Create a file: $SPLUNK_HOME/etc/apps/search/local/ui-prefs.conf
- Create a search stanza like this:
[search]
dispatch.earliest_time = -7d@d
dispatch.latest_time = now
Restart Splunk and you're good to go!

If you are having trouble getting a Linux (Ubuntu, in my case) guest OS to get a network address using "bridged networking", make sure you have installed "virtualbox-guest-additions-iso".
You can install this package through apt-get:
apt-get install virtualbox-guest-additions-iso
As soon as I installed this package, my Ubuntu 15.10 Server guest received a DHCP address and was connected to my network!

Indulge me for just a moment, and consider a future in which you choose a bank just as easily as you choose a gas station. Where banks charge competitive fees for the useful commodity services that they actually provide. Where the banks don't hold a monopoly on access to the financial system. Where individuals like you and I can autonomously contribute to the development and improvement of the financial system.

I just discovered that Simple XML dashboards in Splunk can be customized with JavaScript! That's right, the point and click
dashboards can be customized in a very powerful way. Here's the official docs, and an official example.

Although it's often possible--and recommended--to avoid the join command, sometimes it is necessary to use join. I was recently exploring the performance impact of the join command and I wanted to share my findings.

Part of being a responsible software engineer includes the systems engineering process of configuration management. Although backups and access controls are a necessary part of maintaining a secure IT system, relying on these processes for configuration management is inefficient and dangerous.

Although you can use the Splunk on Splunk app to monitor Splunk index sizes (and many other things!), you might be interested to monitor index growth over time as well. I'll show you how to do that.
Just for demonstration purposes, you can run this search to see the kind of data that we will collect. This uses the rest command to collect the current index metadata from the Splunk REST API. As you can see, I renamed a few fields just for asthetic reasons.

Recently, I needed to delete some events that matched certain summary conditions. For example, where the event count exceeds a certain threshold:

Now, if you try to delete the events by appending | delete, you'll receive an error:
Error in 'delete' command: This command cannot be invoked after the non-streaming command 'stats'

Github is great and all, but it's still a proprietary organization (remember Sourceforge?). How about an open-source github -- where all of the computation and storage runs on a distributed network? The data for all repos could be stored on a blockchain database. MIners will perform execution that is normally performed by webservers today.
Like Bitcoin, your own PC could help run the blockchain, your company could run its own miner servers, or third-parties might run miners as a service for you.
Apps?

I really like how the advent of mobile operating systems has allowed operating system designers to re-imagine how to create an operating system user interface. Isn't it great that even novice computer users can use pretty much any mobile operating system and common user interface behaviors are automatically intuitive and consistent--such as pinching to zoom or rotating a device, tap and hold, swiping. This is a good thing. We should have more revolutionary ideas like this in technology.
