How to Make Effective small talk
Listening to the Jordan Harbinger podcast, I learned a tip about making effective small talk; the F.E.W. approach. Facts, Emotions and Why.
Facts: Start with asking a fact. “Where do you work?” Emotion: Follow up with an emotion. “How do you like working there?” Why: Dig a little deeper “What made you choose the career path?” It’s important to mix this up with statements of your own in-between the questions so you don’t sound like a robot.
I Only Live for the Weekend
Everyone tells me, “Dave, you shouldn’t be living just for the weekend!” But I wonder, how do people who work in a typical 9-5 corporate environment avoid lusting over the liberty and excitement that the weekend brings. Two whole days to do what you want to do; spending time with family or friends, traveling, working on side projects, gaming, etc. For me, it means two whole days where I don’t have to be in a windowless room coding in front of a computer screen for eight hours.

Run Android Apps in Chrome Browser
Let’s take a look at how you can run android apps in Chrome browser. Keep in mind, this is more of a proof of concept than something you should heavily rely on. While simple apps and games will work, you will most likely run into issues when trying android apps with advanced graphics. To run android apps in Chrome browser we are going to use a modified version of the android-chrome runtime found inside of chrome.
What's bad about coding? You can work for hours with nothing to show for it
Last Saturday, I spent several hours working on my website’s code. I added some new meta tags to lazy load images, tried to remove JQuery dependencies from my scripts, added enhancements for accessibility and structured data, and even created a pull request for the theme that I am using (Beautiful Hugo).
Basically, five hours of my day were eaten up by completing those tasks. Although this was another example of getting too absorbed in your side projects, I was actually proud of myself.
I Can't Do Anything for Fun Anymore; Every Hobby Is an Attempt to Make Money
When I was a kid, it was easy to merrily invest myself in any activity that I found interesting. Building robots, learning to play guitar, and making short films were things that I would work on after school everyday. I did all those things simply because I enjoyed doing them.
Now, as a young adult, I feel like I completely lost that spontaneity and simple mindset. Every project which I take up has become an attempt to make money.

The other day I came across a neat drone called the DJI Tello. It is a relatively inexpensive quadcopter that offers a simple SDK which can be accessed over WiFI. Using the NodeJS dgram library, I can send commands via UDP to the drone to perform actions such as takeoff, left 20, and land.
