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
I've recently cited a tweet about labeling you feelings to manage the pain or the overthinking they may cause. I decided I wanted to share my feelings about writing a mobile app for one of my customers. Remember, this is about my own feelings, not the experience of my customer. I'm visiting Oslo, and got … Continue reading Label your feelings
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
When I started programming with C++ exactly 28 years ago, it was with Borland C++ 2.0 on MS-DOS. Then I went to the Windows 3.0 version, had a quick side step with Visual Basic until 2001 when I was back with C++ on Windows 2000 running Visual Studio 6. Then I moved to c#/.NET for a … Continue reading Sharing cross platform C++ code between the mobile and the cloud: Introduction
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
