At ContaAzul , we use the CI infrastructure a lot . We open several pull requests in several projects every day, and we block the merge until the build pass. We consider our master branches are sacred, and we can’t afford too much waiting to change them.

I became a FreeBSD user over 2 years ago when I wanted to see what all the fuss was about. I swapped my y410p dual-booting Windows / Ubuntu with FreeBSD running Gnome 3. I learned a lot during the transition and came to appreciate FreeBSD as a user. I soon began running FreeBSD as my OS of choice on cloud servers I managed. So naturally, when I started working at Linode a year ago I wanted to run FreeBSD servers on Linode too. Linode is a....

Did I mention how awesome it is to live 30 minutes from a ski lift? In March of 2016, I launched a course called The Complete Guide to Rails Performance . Since then, I have distributed just over 1800 copies, for a gross revenue of $220,033.50 (about $1000/week). Although I launched the course in March, I had worked on it for about 4 months. Releasing the course has been a lifechanging event for me. For the first time ever, I made more mo....

It has become rampant nowadays to find many persons misinterpreting or skewing evolutionary psychology studies to praise or blame the stance they fancy or despise. The slants are non-sense and blot this relatively new field of social science by conflating it with bigotry and excruciatingly non-scientific arguments. Many of the pernicious individuals that advance them are confabulating and fabricating ideas to fit their world view. Their tr..

hI started programming with that orange turtle ( I think it was supposed to be green, but we had bad CRT screens ) by drawing stuff on the screen. I think that I was in fifth grade or so. I later graduated to VB (IIRC, that was VB3 or VB4), but my first formal programming education was done in Pascal. And I was pretty good (for a high school kid who merely dabbled), but I just couldn’t figure out pointers. I mean, they made absolutely no se....

I used to think that misunderstanding interfaces in Go can lead, at most, to not very readable code and worse maintainability. From my observations misusing interfaces becomes visible usually during refactorings, where you questioning what this type or abstraction actually represents. But, at least, the code tends to work and it’s not buggy. The bug But here is the interesting piece of code that actually was buggy: err := SomeFun..

So yesterday Visual Studio 2017 was released. Big news. Lots of cool stuff . As I write this I am watching the live stream of the 2 days-long launch event. If you want to learn about Python support in VS2017 though, you have to dig deeper and head over to the Python Engineering blog at Microsoft. As expected , the official release is actually coming out with no support for Python. It will come in a few months. Bummer. In the meanwhi..

Today we are open-sourcing our ODBC adapter for ActiveRecord, which allows Ruby on Rails applications to communicate with ODBC-compliant databases. The impetus for this work was an effort to update one of our APIs to run with the latest Rails and ruby. Along the way we released Rails 3.2.

Once there was a God, And once there was a fire, God looked upon the fire, Burning and searing, And then there was a Man, who yelped, “O God! Help! There is a fire! God cried, “Let there be water”, He said, And Man received water, But the man complained, “O Lord, you are merciful,” … Continue reading A Different Man

Leveraging ReactJS in HackerEarth Assessment Environment

ReactJS , as the name suggests, helps create reactive (read interactive) UIs. If we have a UI with many interactive elements and on each interaction a bunch of elements change, ReactJS efficiently updates and renders the required elements. At HackerEarth, one such UI is the programming assessment environment. Programming assessment environment is one of the most critical products of HackerEarth. The mockup below is a broad idea of what it....

On the Data Science Engineering team, we are constantly working to improve the machine learning systems powering AdRoll’s products. We have recently started investigating Thompson sampling and Bayesian Factorization Machines as a way to ensure efficient exploration of the ad marketplace. In this post, I will illustrate why such exploration is necessary, and then dive into some of the math and algorithms required to make it work. Credit for ....

I’m happy to announce the start of a “short” workshop were I’m going through all the steps to build a complete 64bit operating system for the Raspberry Pi 3. This 64bit HypriotOS is mainly focused on running Docker containers easily on this popular DIY and IoT device. You’ll see that I’m using Docker heavily for each and every build step, because it really helps us a lot to run a local build with Docker-for-Mac or later on the cloud ....

In mgmt we have meta parameters . They are similar in concept to what you might be familiar with from other tools, except that they are more clearly defined (in a single struct) and vastly more powerful. In mgmt, a meta parameter is a parameter which is codified entirely in the engine, and which can be used by any resource. In contrast with Puppet, require/before are considered meta parameters , whereas in mgmt, the equivalent is a gr..

So at the start of January I discovered the One Project per Month project, and decided to give it a go. You can follow my progress here and I’ll also try to post here somewhat regularly about my experiences. The first project was an app that does budget tracking . Well, not really budgeting, more like to track what I was spending. I’ve been wondering where all the money went, and this app was made to help me achieve some visibility a....

I’ve been wanting to play around making Android apps for awhile now. Though difficult, I was able to setup things using Maven and IntelliJ. Almost everything was working - I could even build an APK and install it on my phone - but when I tried to run it on my computer via an Android Virtual Device, I needed to download some components via IntelliJ. Unfortunately, I received the following error:
