In this post, I'l go through our findings to compile and run cross platform C++ code for iOS and Android that consumes OpenCV. The first thing to note here is that I'm not going to expose the OpenCV C++ code directly to ObjectiveC or Java. Instead, I'm using Dropbox's Djinni to abstract it behind a cross … Continue reading Mobile cross platform C++ code part 2: Consuming OpenCV
As I write earlier, I'm back to C++ after more than 20 years. A refresh was needed so I bought this (on the right side of the picture above) to catch up. There's exactly 21 years between those 2 books editions. In the distant early 90's there was no Internet... This is partly why I … Continue reading Mobile cross platform C++ part 1: What’s new in more than 20 years ?
This is the third post of our ongoing series about using PostGraphile. In this post, we'll learn how to authenticate a user with AWS Cognito and use the incoming JWT with our GraphQL client against PostGraphile. The idea behind this is to leverage PostGraphile support of PostgreSQL's RLS. Cognito JWTs The first think to understand … Continue reading The ultimate DAL with PostGraphile part 3: using a JWT coming from AWS Cognito
Update Fri 8 Jun 2018 : I was running into CORS issues with the ApolloClient in React. So I enabled CORS with the --cors option while I'm still in development. This is a multipart blog post about using PostGraphile. Part 1 is here. This 2nd post only goes through the tricky steps required to connect … Continue reading The Ultimate DAL Part 2: Running PostGraphile in an AWS EC2 with RDS
The problem You probably know by now that I hate writing boilerplate data access code. When you have to write a data access layer, I used to think that the code should be generated from the database structure and could be regenerated on demand, otherwise you're losing your time. That was before... The previous solutions … Continue reading The ultimate Data Access Layer with GraphQL Part 1 : Postgraphile
I'm working on a project for one of my client that will require us to share native C++ code between iOS and Android then consume this code in React Native. A quick google search led to several toolkits and samples on GitHub. This is great, I'll have a starting point to play. I have forked two … Continue reading A tale about using Open Source Software
The last time I heard about chaos engineering was about Netflix at AWS re:Invent 17. And I thought to myself, that in my last job, we were doing chaos engineering as a service. That is: Writing code thinking that it could not fail. Working with sometimes poorly defined user stories. Using early open source software … Continue reading Chaos engineering as a service
