Everyone knows LinkedIn – yet not everybody use it to its full power (and I totally include myself in this “everybody”). Linkedin has a lot of potential and here are some interesting tips I would suggest you have a look at. Some history & stats Founded in Dec, 2002 (When Windows XP was still at the top of its hype) Launched in May, 2003 (yes, you were a couple of years younger…)

We have a new tech talk coming up on May 17th, from our very own Dominick LoBraico. This one is about how to represent configurations with programs. In some sense, this is an obvious idea. Lots of programmers have experienced the dysphoria that comes from watching your elegant little configuration format metamorphize into a badly constructed programming language with miserable tools. This happens because, as you try to make your configs c..

For visualizing and alerting on your infrastructure and services, Grafana is awesome, and its power gets amplified when dashboards and alerts and be templated to work with your constantly evolving infrastructure. So how do we decide how to apply templates to the right set of servers and services? Well, of course you can preseed key-value pairs on your servers and have your collector agents like Telegraf work off of your seeded data. However....

I've been coding a project build on AWS Lambda and I wanted to post a unit testing pattern that has been really helpful especially for input validation. The lambda function input starts with an "event" object which I'm sure in the first version of lambda was reasonably small and simple, but now it can get quite complex with many deeply nested properties when API Gateway authorizers and path parameters are involved. Thus I've been applying t....

Problem: Determine if two polynomial expressions represent the same function. Specifically, if $ p(x_1, x_2, \dots, x_n)$ and $ q(x_1, x_2, \dots, x_n)$ are a polynomial with inputs, outputs and coefficients in a field $ F$, where $ |F|$ is sufficiently large, then the problem is to determine if $ p(\mathbf{x}) = q(\mathbf{x})$ for every $ x \in F$, in time polynomial in the number of bits required to write down $ p$ and $ q$.

Remember just a few years ago when your customers started tweeting at you, angry about a delayed flight, complaining loudly about a poor product or “the worst service ever!”? At least you had a social media presence—unlike some of your competitors—but I bet it really took time and effort to learn how to use social media effectively. It may even have caused substantial public embarrassment and pain along the way.

Trailblazing the first delivery of a software system requires courage and conviction, especially on projects that replace existing business critical software. When I’ve been acting as system architect I’ve employed a number of tricks in order to structure functionality and technical solutions in such a way that we can complete these early deliveries without sleepless nights. The most important is to find a subset of functionality that c..

Once upon a time there was an ugly truck. He was a lonely soul, a poor mess of rust and twisted metal, left to idle all alone. While certainly a sad state of affairs, it hadn’t always been this way for him. In his youth as a rental truck, he’d helped families move every which way. Later, he became a work truck, the lifeblood of an independent carpenter. As fulfilling as his past had been, it had also left its fair share of chips and dent..

I’ve observed a sharp uptick of developers and systems administrators interested in “getting into DevOps” within the last year or so. This pattern makes sense, too: in an age where a single developer can spin up a globally-distributed infrastructure for an application with a few dollars and a few API calls, the gap between development and systems administration is closer than ever. While I’ve seen plenty of blog posts and articles about coo..

At DockerCon 2017 in Austin I gave a presentation of a Raspberry Pi cluster mixed with some UP boards. The audience really liked the visual effects of the Docker Swarm scaling a service up and down. So I show you some background details what you need to run that demo on your Raspberry Pi cluster as well. All the effort played off to build that cluster, to find out how to drive LED’s in swarm mode, to put it into my bag and go throug....

Just over a year ago, my son Wyatt received his first computer for his sixth birthday. It’s a Raspberry Pi, and he has an old LCD monitor, and a kid-friendly mouse and keyboard. I purposely waited until he could read before starting to teach him about computers. He’s a pretty smart kid, reads a lot (a Harry Potter book in a weekend), and is somewhat socially awkward. Perfect for a programmer. The Raspberry Pi doesn’t have a cover on i....

It’s often surprising just how much software performance depends on how the software is deployed. All the time and effort you’ve invested in optimization can be erased by a few bad decisions in scheduler policy, affinity, or background workload on a server.

As mentioned in my Working on Android post , I’ve been using a mechanical keyboard for a couple of years now. Now that I work on Flowhub from home, it was a good time to re-evaluate the whole work setup. As far as regular keyboards go, the MiniLa was nice, but I wanted something more compact and ergonomic. The Atreus keyboard Atreus is a 40% ergonomic mechanical keyboard designed by Phil Hagelberg . It is an open hardware design....
