Establishing a Websocket PUBSUB server with Redis and Asyncio
Motivation If you've been following my never-ending quest for a light-sensor setup as detailed first in this post (set up a Raspberry Pi with Python 3.5) and then in this other post (make a light sensor with an Arduino and Raspberry Pi), you would know that I've only set up the data-collection half of this project. The other half will involve getting the data to make hardware do stuff in the real world. This post in particular covers how to leverage a PUBSUB (publish-subscribe) Redis server and websockets to this purpose.
7 Top Tools for Mobile Product Development
Developers are drowning in tools. In fact, as of this March, there are 246 mobile product development tools on the market for just one operating system: Android.
3 Mistakes Your Product Development Team Might Be Making
Years ago, while working on the second version of Weathermob — a social weather app — we made a mistake. The app had traction, but it also had flaws that we were correcting to help it reach the next level of growth. Rather than solicit user feedback on our new developments, we built and released the new iteration based on our assumptions about the product’s existing user base. While the relaunch was a success, it did upset a small-but-vocal cohort of users. Small things like font size and interface changes, which we thought were improvements, frustrated a key user base: seniors who enjoyed talking about the weather. We’d failed to do our homework, and we had to make last-minute changes to address the situation. Worse, we’d missed a big opportunity to show our users that we understood their needs.
Get the Most Out of Git: 7 Best Practices for Budding Developers
If you work with software, like most developers, you probably use Git and know the basics of it. (If not, check out our “How to use git? A beginner’s guide” blog post.) But are you getting the most out of it? Although every team’s workflow is unique, some best practices stay constant. Let’s take a look at a few of my favorites:
10 Tips to Designing & Developing an App That Keeps Users Coming Back
Nobody wants to build a forgettable app. But with more than 2.2 million apps currently on Apple’s App Store, standing out in consumers’ minds is easier said than done. When developers and designers get it right, apps are big money. This past December, the App Store posted $3 billion in purchases. In fact, New Year’s Day 2017 marked the App Store’s busiest day ever, in no small part thanks to Nintendo’s newly released Super Mario Run. The throwback app made history with a whopping 40 million downloads in just the four days following its release. How can developers follow in its footsteps? The following 10 best practices are key:
