The year is already half over, meaning this is the sixth blog statistics report with six more to go this year. I’m looking forward to December’s end-of-year report when I can graph these values, although I suppose six values are enough to graph.

So this is your setup. You’ve using Jetty to serve your web application, and you’re deploying it via Docker to AWS Elastic Container Service (ECS), and you place it behind an AWS Elastic Load Balancer (ELB). You aren’t living in the past so you enable HTTPS on the ELB. Your clients connect via HTTPS to the ELB, and the ELB connects to your application via HTTP internally to AWS. So the last thing you want is for users to receive a redirec..

This past spring, I had the pleasure of attending SREcon18 in Santa Clara, California. If you have never heard about SREcon or the term SRE then let me diverge for a moment to describe. SRE, or Site Reliability Engineer, was coined by Google employees back in 2003 when a team of software engineers were tasked with running a production environment. It’s the new hotness in the technology world, so an internet search will turn up a bunch of to..

I think it’s time to go through what happens when you power on the STM32 Cortex-M microcontroller. There is a lot of resources on this topic (if you are reading this one… thank you!). I will explain this process in my own words. You have powered on your microcontroller. Less than a second has passed and it is already munching through data, sending and receiving messages, controlling motors and blinking leds. In less than a second (waaaa..

My life may or may not consist of a series of questionable (and sometimes poorly thought out) choices that are ever so slightly outside my comfort zone. Even with a long line of shaky choices to choose from, a recent choice (and the topic of this post) might mark the climax of my personal brand of impulsive opportunism. Since I’m wholly unable to structure my posts for dramatic effect and gave away the surprise in the title, what I’m tr..

I just got back from watching the Incredibles 2. The previous movie was a favorite a mine from first view, and it is one of the few movies that I can actually bear to watch multiple times. I was hoping for a sequel almost from the moment I finished the first movie, and it took over a decade to get it. I actually sat down with my 3 years old daughter to watch the first movie before I went to see the second one. I’m not sure of how much she ....

The email fun in Emacs continues. After a few weeks since I started using mu4e and offlineimap , I'm sold. Both are awesome. Mbsync is an offlineimap alternative. Despite resyncing all my mail, the transition was fairly smooth. Here's how… Install isync (for mbsync) brew install isync Configure mbsync Mbsync uses ~/.mbsyncrc for configuration. Migrating ~/.offlineimaprc to ~/.mbsyncrc looks like: IMAPAccount Personal Host some.im....

I have played with Python’s SymPy symbolic math library before, but for the first time last week I used it to solve a real problem! In the process I had to confront three errors in my understanding of how SymPy works: I had somehow imagined that SymPy was secretly storing all the equations I was writing and would use them automatically later. I thought I could convince SymPy to eliminate intermediate symbols. I thought each variable in ..

I was doing some code review today and I realized after the fact that the refactoring I wrote for the review was a great example of how I iteratively evolved a piece of code into something really great. So here’s a step-by-step approach to finding and performing a code refactoring you can be proud of.

Wireguard is the hip, new way to VPN :P No, but seriously I wanted to try it out because it is super interesting and I think the direction it is going is awesome. Read about it on their website if you have not already. What is cool about Wireguard is it integrates into the Linux networking stack so you have a lot of power over interactions with it. In other words, it is very easy to clone the interface into specific containers. Or ju....

It’s quite a challenge to climb Mount Shasta. It’s an active volcano and as a result, it’s high and steep. At 14180 feet it is the fifth highest peak in California. With 3000 meters of vertical prominence over the nearby town of the same name, it stands like an Eiffel Tower over the surrounding area, except that the Shasta tower is ten times higher. According to Wikipedia, it is one of the one hundred most prominent peaks in the world https....

In our final installment for the Higher Level Function in Python Series, we dive into the Python filter function. No sidetracks this time around. We simply take a look at how it's used, try to find a way where it would be superior to list comprehensions, fail, and conclude the series.

Last Tuesday I was Table Topics master at my local Toastmasters meeting, which means I had to choose questions or topics that the other members had to give a one to two-minute speech. Being that the 4th of July, Independence Day here in the United States, is approaching, I decided to theme my questions about that holiday in particular.

At times, you may need GNU versions of command line utilities on macOS. For example, GNU find. As usual, Homebrew saves the day. Install with: brew install findutils Unless you install with –with-default-names (I don't), GNU utilities will be prefixed with a "g". gfind --version If you need more, there are others: brew install binutils brew install diffutils brew install ed brew install findutils brew install gawk brew install gnu-..

In the digital age you stumble on concepts analog in their nature. Modern graphics are created on a computer yet they originate in an analog process. You constantly change the brush size yet the computer allows you to do it in an increments. Do you actually care your color is R=53, G=123, B=200 in numerical values except when moving the data? Concept of making an analog controller for art creation on the computer was always interesting ..

One of our most frequent feature requests recently has been for the ability to generate an API token that isn’t tied to a particular user. We’re excited to be able to now offer our pro and enterprise customers the ability to create service accounts – a special type of user that has an API token associated with it.

Have you ever had a hard drive which runs out of space while there is still space remaining? Have you ever wondered where that space goes? Let me show you a magic trick First I’ll save a message in message.txt Nothing here nothing there, I’ll save two secret messages the first one is a secret, the second one a big file of text. (but I could save a jpg or an exe).

Originally appeared on Opsgenie Engineering Blog If you are deploying serverless applications in AWS Lambda and using Java, you are well aware of cold start problems. Cold start happens because of the way the Java Virtual Machine works, it kicks in JIT (Just-in-time), and it needs to “warm-up” like a car from the 80s. AWS Lambda caches containers for you, so when idle, it is paused and brought back online immediately as soon as a request a..

A work colleague (let’s call him Owen as that’s his name) asked me the other day “I dont understand the problem space scc et al solve. If you wanted to write a short post, i’d read and share the hell out of it. Basically, it seems like a heap of people can see the need for it, and I’m trying to understand it myself” Owen is one of the more switched on people I know. As such if he is asking whats the point of tools such as scc, tokei..
