Introducing three open source libraries for working with Ona and data
We are proud to announce preview releases for three Clojure/ClojureScript open source software libraries: Hatti, Milia, and Zebra Lite. We are actively working on and improving these libraries for use in our own software and by others. In alphabetical order the contributors to these libraries are geoffreymuchai, pld, prabhasp, royrutto, ukanga, and wilo99. We will followup on this post with additional tutorials and introductions
Making Ona reliable and resilient
Last year, we experienced a few small periods of downtime. We made changes to bring this up to 99.8% API uptime in 2015. However, the remaining 0.2% bothered our engineering team, so after additional work, we recently hit a rewarding milestone: 30+ days of 100% uptime on our API and front-end site! The first big
Open Street Map as a global "check-in" service
Getting more out of Open Street Maps? At Ona, we’ve always been big fans Open Street Maps (OSM). What’s always bugged me is I felt (like many groups), we’ve failed to fully understand and leverage the incredible wealth of data that OSM represents. Sure, our basemaps are powered with OSM data. And yes, we encourage partners
KLL Humanitarian Quake Map now available as basemap in Ona
Source: Remembering the Lost – Map of Stolen Sculptures from Nepal The Nepal earthquake has shown how important open map data from Open Street Maps (OSM) can be in a humanitarian crisis of this magnitude. Our friends at Kathmandu Living Labs and MapBox worked together to develop a print friendly map that highlights key infrastructure, critical after an earthquake, like
Small Data helps Big Data solve Big Problems
A recent article in the New York Times describes how organizations are using small survey based datasets to enrich the big data sets that usually get all the hype. Alex Peysakhovich and Seth Stephens-Davidowitz argue that survey data goes hand in hand with big data: Big data in the form of behaviors and small data in the
Assessing the quality of adolescent health services in Brazil
Workshop participants visited a local health facility on the last day In 1960, the national capital of Brazil re-located from Rio de Janiero, on the Atlantic coast, to Brasilia, which is in the central-west highlands of Brazil. Even though Oscar Niemeyer’s masterpiece in modern urban architecture doesn’t boast the beaches or invoke the same image

Ona at the Nairobi Functional Programming Meetup
Okal Otieno and Roy Rutto from Ona were the featured presenters at the inaugural Nairobi Functional Programming meetup. The meetup was conceived by Okal and Roy to “discuss the core concepts of functional programming, why use it, and experiences using it.” The iHub UX Lab graciously hosted. Okal started off by explaining how functional thinking can
Writing Python Code to Decide an Election
Yesterday Peter from Ona spoke at PyConZA 2014 about Ona’s work building the vote tallying system for the Libyan Constitutional Assembly Election last February. The abstract and slides from Peter’s talk are below: Earlier this year Ona was given three weeks to write the software that will tally votes in the Libyan elections and decide who wins and who
Pallet Multiuser Configuration
The last time we talked about Pallet we described using a pallet.clj file in concert with Leiningen to bring up remote servers, configure web applications, and deploy new version of web applications. We glossed over the details required for sharing deploys amongst a group of developers, i.e. allowing multiple developers to deploy to the same web server. These details were obviously
