3 Roads Less Traveled for Management-Averse Developers
Think about the last fork in your professional journey. Did you take the path trod by peers? Or did you look past the obvious options for the route that's right for you?
Cool Tricks with Animations Using requestAnimationFrame
If you've been following my never-ending adventures with light sensors (see here and here and here), you'll see that I have yet to make any cool things subscribe to my Websocket server. This post will be less about having the browser communicate with Websockets, and even less about light sensors, and more about some tricks that helped me when using the low(er)-level animation API requestAnimationFrame as I was writing a web-browser subscriber for a Proof-of-Concept.
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.
