Sharing an EFS Filesystem Across ECS Instances, Services, and Tasks

In application hosting scenarios, it is common to have data that must be available to all application instances. Often, this data is stored in a database (e.g. AWS RDS), or some other centralized repository (e.g. AWS S3). However, situations arise where third-party software expects data to be on the filesystem, or where application instances generate files which must be immediately available to all other application instances.

Don’t Forget to Kick the Tires – On Automatic Monitoring & Human Intervention

With as much as we use modern technology to automatically monitor, observe, and report on so many different systems, I think it is important to manually check the viability of these same systems from time to time.

While the quality of sensors and metrics always seems to be improving, there are still loopholes and lapses which make human oversight and investigation important. I have experienced a few situations in the past few months where the electronic/computer-based monitoring solution for systems have failed in ways that could have been particularly costly; yet human intuition and manual intervention ensured that the situation was addressed appropriately to avoid real damage or loss.

Amazon Lambda Auto-Deployment For Your Alexa Skill Using AWS CLI

My latest project includes integration with Amazon’s Alexa voice service. My coworker Jordan already wrote an excellent post on how to get started writing your own Alexa Custom Skill. Amazon’s API makes it relatively easy to develop a new Skill, and with a number of languages to choose from (Python, Node.js, Java, C#, etc), developers can create a simple Skill in a weekend.

Utility to Initiate the Rebuild of Indices for CouchDB Design Document Views

I recently worked on upgrading a CouchDB instance and migrating it to a new server. Because of the upgrade and migration path, I needed to dump all data from the existing CouchDB, and then load it into the new CouchDB.

Fortunately, the Python libraries for working with CouchDB provide a convenient set of utilities to snapshot a CouchDB instance to a MIME multipart file, and then load that MIME multipart file into a new CouchDB. Although the utility handles all documents, attachments, and design documents, it does not provide a way to initiate a rebuild of the indices for views associated with design documents. I wrote a simple utility to aid in this process. Read more on Utility to Initiate the Rebuild of Indices for CouchDB Design Document Views…

AWS IoT Help Button

We recently moved into our new building at 1034 Wealthy in Grand Rapids. The new building is much larger than our old one, and I find myself running around much more and stationing myself in different areas, depending on what I am actively doing.

To help ensure I can provide timely hands-on help—particularly for our printer (which is a common source of problems)—I procured one of the new AWS IoT buttons and programmed it to page me when pushed. Read more on AWS IoT Help Button…

Easy Secure Web Serving with OpenBSD’s acme-client and Let’s Encrypt

As recently as just a few years ago, I hosted my personal website, VPN, and personal email on a computer running OpenBSD in my basement. I respected OpenBSD for providing a well-engineered, no-nonsense, and secure operating system. But when I finally packed up that basement computer, I moved my website to an inexpensive cloud server running Linux instead.

Conference Room A/V Build-Out

We recently moved to our new building at 1034 Wealthy. We took the opportunity to update the A/V equipment for our conference rooms. Previously, we largely relied on projectors for presentation capabilities, an external USB microphone/speaker for audio, built-in webcams on laptops for video, and a table where we staged everything. This worked, but it was certainly not ideal. With the new building, I had the opportunity to standardize a new conference room A/V build-out that would be better suited to our needs.

How (and Why) to Log Your Entire Bash History

For the last three and a half years, every single command I’ve run from the command line on my MacBook Pro has been logged to a set of log files.

Uncompressed, these files take up 16 MB of disk space on my laptop. But the return I’ve gotten on that small investment is immense. Being able to go back and find any command you’ve run in the past is so valuable, and it’s so easy to configure, you should definitely set it up today. I’m going to share how to do this so you can take advantage of it as well.
