Sum Algebraic Data Types in Haskell and Swift

"Grove Park Traincare Depot and sidings" (CC BY-SA 2.0) by train_photos Engineers at Metal Toad participate in a variety of continuing education such as the Hackathon, dedicated time for professional development, and various interest groups for a variety of topics like machine learning and iOS/Android development. Haskell I recently joined the interest group on functional programming in Haskell. We start with an introduction to Algebraic Data Types.

Momento Mori

In April of 2017 I put a widget on my phone that reminds me that I’m going to die. This is how it improved my life.  A long time ago I learned about the concept of Momento Mori. It’s a simple phrase that is held up by the trussing of history and hardened by philosophy. It means: “Remember that you must die."

Finger pushing the publish button

Push the publish button already

The most important measure of progress in building blogging expertise is not word count, it’s how many timers you hit the publish button. Every post is either a rock or a gem dropped into the water; the rocks will sink and be forgotten but the gems will be scooped up and shared.  Drop enough rocks in the water and you are more likely to create a gem.  So push the publish button already.

Proxying MS SQL connections using PuTTY

Connecting to a Microsoft SQL Server database isn't too hard, most of the time. But, what if the database is in your office, and you want to access it remotely, but you don't have a VPN? There is another way to connect, using PuTTY and port forwarding. All you need is a server in the office which accepts SSH connections and can connect to the SQL Server. This will serve as a gateway or makeshift proxy server. With the proper port forwarding setup, you can connect to your database from anywhere.

The Art of Sprinting: It’s Not Just for Software Development

As a sequel to the article I wrote last month about the process and technology improvements I helped design/build firm Design Platform make earlier this year, I wanted to highlight another change that they implemented that transformed their workflow efficiency: Two week sprints.

Leveraging Structs and Generics in the Networking Layer with Swift 4 (An update to objc.io Swift Talk)

Swift Talk #1 and #8 introduces an approach (hereinafter alternative approach) to using structs and generics to build a networking layer in Foundation. The original code was written in Swift 2.2. Here, I will make an update for Swift 4, incorporating the use of newly available JSON parsing features. I will also show how it could be extended to fetch images.

Q4 Hackathon Theme: Machine Learning & Data Science

I was dusting off my copy of Ray Kurzweil's The Age of Spiritual Machines today, and found a fascinating chart (adapted below). The book was written in 1998; it's interesting to reflect nearly 20 years later we're more or less on schedule. $1000 will buy you an electronic brain with a "thinking" capacity somewhere between a mouse and human.

Origin Protection with AWS WAF & Shield

Amazon has been steadily improving their CloudFront CDN offering with WAF (Web Application Firewall) capabilities. This is a great feature, however it's ineffective if origin servers can be attacked directly, bypassing CloudFront. With a little extra work, access to the origin can be restricted. The solution is to add a secret header value at the edge, and configure the load balancer to block requests that are missing this secret. This is necessary because CloudFront distributions are not…

Drupal 8: Migrating data from JSON files

The beauty of Drupal 8's built-in Migrate module is its flexibility. Lots of people will likely use it to migrate their Drupal 6 or 7 sites, but that's not all it can do. In fact, it's capable of migrating data from just about any data source PHP can read. The first few times I used Migrate in Drupal 8, I was migrating data from a MySQL database into Drupal. See my previous posts about the topic here.
