A while back, digging into an old DO NOT DELETE backup folder in one of my old hard drives, I stumped upon a folder called parchis, and for a moment I held my breath until I found some *.bas files there! So what? Well, I just found the lost source code of my very first project, the one I coded while learning about variables, procedures and loops, the one that made me realize that this is the kind of stuff I wanted to do as my professional career and hobby.
If you are a AWS SES user (AWS’ email system) you probably know that working with its JSON based templates is not a user-friendly task: Text and HTML content are defined as properties of a JSON object It’s a JSON file, meaning that you have to escape some characters, like " in the HTML It’s quite hard to find the content to change in the HTML being stored in a single line But still, is a quite convenient system, as hosting your own email server is quite an effort, and you want it to be reliable.
Definition: A monorepo is a standard Version Control System, or VCS (such as Git, Subversion or CVS) repository, which instead of containing just one application or unit of software (applications, libraries, micro services, modules…), contains all the components that a project (or company) needs to operate. At first glance, it sounds counterintuitive to host more than one unit of software in a single repository, but there are few advantages on having all components stored in the same place:
It’s been a while (well, years) since I rotated my GPG keys, and to be honest, now that I know better how to handle a GPG key pair in order to avoid master key rotation, I think it’s the time to get a new pair. This tutorial will show you the steps I followed with explanations on what we are achieving in every step. Environment This is the GnuPG version used in this tutorial (if you are using a different version, probably not every command would work the same, but I wouldn’t expect for the concept to change that much):
In the previous post we explained from a theoretical point of view how a block chain works. In this post we will get down to work and will implement a working blockchain in Go. If you haven’t read it yet, we recommend you to do it now before continuing. It’ll provide you the basic concepts needed to understand the examples below. (You can find the complete example in this Github repository: https://github.
Blockchain is one of those buzzwords everyone is listening nowadays, but what it really is? In this series of posts we will dig one general concepts about BlockChain and a little bit of its relation with BitCoin, as well as we will develop a simple blockchain in Go. To put it simple, and as its name states, it’s just a chain of blocks. The interesting detail is that is a cryptographic chain providing some characteristics that make them really useful:
In this tutorial I’ll show how to piece together the required NPM modules to build a REST API in Node.js with proper Swagger documentation. We’re going to use Express as the HTTP framework, and the Swagger documentation will be written as inline comments within the code, as close as possible to the handling endpoint or models that will implement the contract, so it will be harder for them to eventually diverge.
Recently I took the decision of leaving my long beloved distro – Ubuntu (sorry, link in spanish) and moving forward into Arch Linux. And why? As JFK said when the USA was aiming to land on the moon, “not because it’s easy, but because it’s hard”, maybe not that much compared to getting to the moon, but definitely more tedious than Ubuntu. One thing you can take for sure if you take the chance to install Arch: no matter if you success or give up with it, you will learn something new about how a Linux distro works.
Packages in Java is a quite simple and straightforward concept of the language. It’s there from the beginning and it’s commonly used by every Java programmer. In a few words, these are the rules you have to follow to create a class inside a package (spoiler: which are not completely true, as we’ll see later): Package statement must be the first one specified in a java class file A package namespace must match the physical path of the file, i.
In little less than a week, a new edition of Coursera’s course, Principles of Reactive Programming from Martin Odersky, Erik Meijer and Roland Kuhn, is launching. This course is a follow-up of Principles of Functional Programming in Scala, which I took in its first edition and which I enjoyed a lot. I’ve regretted missing out first edition of this second course for a long time (more than a year, in fact), so if you want to learn about this magnificent frameworks of the Scala world, don’t miss this chance!
