Domain Driven Design with React Native

Problem: how to guide programmers to implement domain driven design and modular architectecture Relevant technologies used: apollo client graphql react native nodejs redux As a programmer I am always inclined to prioritise technical detail and just making things work. One of the techniques to prevent building monolithic code bases closed to expansion is constant refactoring. An architecture trick I picked up from developing Domain Driven Design is to twick the questions I would usually ask myself when refactoring from a question about the domain instead of it being about the [Read More]

Do the AngelHack - checked

I recently got into hackathons and I feel like I can’t stop. Angelhack was the best excuse for me to leave Exeter for a week-end and join the people that accepted the AngelHack challenge in London. Just finished a day-long week-end, got some sleep. Must say it was the first time for me when I just wanted to work and not care about sleep at all, but I am strange that way. [Read More]

Course Completion - Review - Node Program: From 0 to Hero with Nodejs

I discovered him through his blog while I was looking to solve some problems, he goes through the basic stuff and gives the feeling that he can respond clean and short to questions about the material. Main takeaways: Understanding of async programming and basic understanding of web programming in nodejs Acquired knowledge of server constructs and basic modules Illustrations of some of the greatest pitfalls Pro: [Read More]

Learning new programming languages

Looking for the new hit or sticking with your known language ? is this one of the big questions you are looking to get an answer to ? First and foremost I want to begin with a saying that most programmers overlook: “A programming language is worth learning if it changes your way of thinking”. With that in mind I want to make some people question they allegiance to a certain programming language. [Read More]

Exercise your programming skills online

A quick review of websites in the nurturing your programming skills industry. I am so grateful there are so many websites where you can grow your programming skills to choose from. I have seen many employers use codility, but I am more inclined towards using hacker rank, the editor and tests from codility are so tedious and there is no transparency as to what is required from you, you really need to practice with them before, even then you might fell short, as I’ve done a few times.

Using MariaDb FlexiViews

In the quest to filtering data I ended up looking for a tool that allows me to move a part of a query that needed too many unions in order to achieve simple things that where not thought trough from the beginning. Task at hand: make a step in moving from a faulty database design to a new organized data model don’t affect current query performance reduce the effort in building the query from backend apply conditions like using a field in a joined table for deciding the type of join the query needs keep query maintainable A database view comes usually with the disadvantage of not having indexes like a table does, it depends on the performance of the query builder and most of the time is intended at shadowing sensitive information from possible sql query vulnerabilities.

Php resque pool

Resque is a great tool for creating background jobs, but the task of managing the queues and maintaining is not quite as straight forward. There is quite a lot of noise and a nice amount of options when it comes to translations of the resque pool to php language. Some people might wonder why would anyone translate the tool to another language. I did too, but it is real value in having the majority of tools under the same umbrella. [Read More]

Mysql Certification for developers - first try - first failure

For anyone looking for feedback on Mysql 5.6 Certification exam. As a general impression if you work you queries on a weekly basis you should be safe just by practicing some more of that preparing for it. I must say to begin with I was overwhelmed when reading the table of contents for the Certification Exam by the amount of chapters I thought I have not covered well. Big mistake, most of the questions where from a developer’s daily activity like interpreting results. [Read More]

IoC - Understanding the need for binding interfaces to implementations

I found myself confused by this need of binding the interfaces to an implementation, maybe you have too. I like explaining this kind of things by looking for the root of the problem it solves, as by itself it might not make sense. If you are not familiar with the Inversion of Control container you might want to take a look at topics like this What is Inversion of Control? [Read More]

Docker for the simple programmer

Another definition

I’ve been asked a lot what is docker lately and i found it difficult to adapt to each listener, but this video cleared all my doubts and I think it should be enought for all the english speaking programmers out there (i don’t really think that there are programmers that do not understand English, though)
