Today’s blog post is brought to you by one of our customers DeansList software. Thank you Matt for sharing your experience with our community.
At DeansList, one of the things that we do really well is build custom report cards that students take home (or get e–mailed) to their parents. We build them from the ground up with every school – taking instructions on everything from design to data points to the placement of charts. They often go home every week and, in addition to keeping parents up–to–speed, they include them in the messaging, programs and structures that engage their children every day.
Ugly, but functional.
Not surprisingly, with the promise of customization come very unique requests. Lots of our schools include fake paychecks linked to a school’s token economy – a tool to teach financial literacy. Additionally, many schools we work with serve large populations of families whose primary language is not English (often Spanish). Whenever possible we translate our reports into a second language on the back, so non–English speaking parents aren’t missing any important details. The challenge we faced was translating integers into Spanish words for the second line on the check (i.e. $430 into cuatrocientos treinta dólares). We wrote out a script to translate numbers to English words, but no one on our team has the language expertise to do the same in Spanish. It admittedly wasn’t a huge priority so we kept the words in English – ugly but functional.
Around the time we were tackling this we came across Algorithmia and it’s Bounty feature. It seemed like a longshot – but what’s the harm in asking? So we posted a request for someone to write an algorithm to Translate Integers to Spanish Words.
A Bounty Fulfilled
To be honest, after I created the bounty, I forgot about until March 2nd when I got the “Your bounty has been completed” e–mail. A user named Javier had uploaded Cardinales. I logged right in, threw some tests into the web console and, within diez minutos, was hitting the API successfully via Postman.
The Algorithmia-driven solution!
Algorithmia’s libraries plug right into any platform, and we considered using their JS on the front–end. However, for a few reasons, wrapping an endpoint to our internal API around a call to Cardinales made the most sense. First, this feature will likely get deployed again in many more schools – so abstracting it gives us more flexibility to change things around as needed. Secondly, school firewalls can be incredibly restrictive, so having the browser request the data via our server keeps all our calls in the whitelist and eliminates troubleshooting hard–to–pinpoint issues.
Safe and Secure
What’s awesome about Algothmia is it’s not inside our system, and we don’t need to provide Cardinales any kind of student data to work. We just send it a # – 354, and it comes back to us with the translation: trescientos cincuenta y cuatro. Everything happens via cURL and there’s no trace of Algorithmia or Cardinales code on our servers.
Considerations for Next Time
Or, How to Write a Better Bounty Spec…
Javier went above–and–beyond and included things in the solution that we didn’t ask for, like translations in both the masculine and the feminine, and proper translations for negative numbers. Still, now that it’s up and running, I realize there are a bunch of things we could have thought more about when we wrote the spec.
- Multiple items in a single request – Right now, we send one number at a time, and receive one translation per request. This means there’s a lot of overhead if we print 100 students reports at once. Next time around, I’ll include the ability to send an array of inputs, and receive key–value pairs as a return.
- Error codes – Cardinales handles bad inputs gracefully. Sending “abcd” returns empty quotes. However, more elaborate algorithms might require more detailed error reporting. It’s definitely something we’ll keep in mind going forward.
As more schools build savvy data teams, we’re always looking for ways to help them integrate their efforts with our own. We have a public API, but I could also see Algorithmia as an easy, cost–effective way for them to contribute their own highly–specific code without having to think about setting up their own infrastructure.
So far, leveraging Algorithmia for a non–core feature like this has been an easy, awesome experience. Our engineers were stoked to plug this in and so far it works perfectly. I’ve never met Javier, but I can read his code (it’s elegant), he’s contributed meaningfully to our platform, and I appreciate his work. Gracias!
