Hi !
We had an amazing time last week with Ivana at the Global XR Talks, sharing some of our lessons learned creating an Mixed Reality app to work in Hololens 2 and Azure Kinect.
As usual, now it’s time for slides and code
The main scripts for Camera and Cognitive Services interaction are available here https://github.com/elbruno/events/tree/main/20200806%20Global%20XR%20HL2%20to%20Azure%20Kinect%20Lessons%20Learned
Hi !
Quick post today, with mostly sample code. And, it’s all about a scenario that we faced with Ivana a couple of days ago while we were using MRTK and we were trying to use some Cognitive Services.
As of today, not all the services in Cognitive Services are supported and have official Unity3D support. At the end, it’s not a problem, we can just make an HTTP Post call, and that’s it. However, this is not as easy as is supposed to be.
So, after facing some issues with the System.Net.HttpClient library, I decided to use UnityWebRequest. This library main objective is to work with HTTP Forms, however we can manage to send an image with a sample like this:
As we can see in the previous post, there is no async / await support here. So I added a couple of ugly lines of code to support this. We can improve this to have a timeout or delay applied here. As for this sample, this works great.
As a bonus, you can watch the full presentation in the Global XR YouTube channel here
Happy coding!

Blazor es uno de los frameworks para Web Assembly mas avanzados del momento y por otra parte SignalR es una librería ligera y fácil de implementar, que nos permite incorporar comunicación en tiempo real dentro de nuestras apps, en este post aprenderemos como combinar estas 2 tecnologías.
Como es usual lo primero que debemos hacer es instalar la librería de SignalR y configurar nuestro hub:
Podemos hacerlo desde el gestor de NuGets con Visual Studio o podemos utilizar el comando en la consola:
Install-Package Microsoft.AspNetCore.SignalR -Version 1.1.0
Debemos configurar SignalR de una manera general en el proyecto agregando el middleware y utilizando services.AddSignalR(); y endpoints.MapHub(“/chat”); en Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddSignalR();
services.AddResponseCompression(opts =>
{
opts.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat(
new[] { "application/octet-stream" });
});
services.AddCors(options => options.AddPolicy("CorsPolicy", builder =>
{
builder
.AllowAnyMethod()
.AllowAnyHeader()
.AllowAnyOrigin();
}));
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) {…

Hi !
Quick post today. When I started with Hololens 1, Unity and the Hololens Toolkit a couple of years ago, I did this exercise to have a sense of the required disk space for my projects and tests.
I realize that I didn’t blogged this, so here is an updated version using the latest versions. Here are the tools and versions I’m using:
And using this tools I follow the steps defined in “Initializing your project and deploying your first application” (see references). Let’s take a look at the disk usage.
So, as you can see, a ready-to-go final project will require around 3.5 GBs disk space. Get ready your credit card for a new SSD !
Happy coding!

Buenas!
Hoy tenemos la suerte de hablar con Fernando Guerrero y Juan Quijano sobre sus experiencias como CEO. La pregunta “Qué hace un CEO_” es parte del podcast, sin embargo, lo más interesante es ver como estas iniciativas crecieron a nivel mundial, como el talento y el trabajo fueron pilares importantes de su éxito.
En el camino también aprendí que Atari, si Atari, no solo hacía consolas de videojuegos; esto y mucho más!
Happy coding!

Hi !
A couple of days ago, I wrote about how I like Portainer as a visual interface to manage docker (see references). In one of the comments, Marco suggested also an option to automatically update all my containers.
As I explained in my post, the basic steps for this are
Super easy, but tedious if you need to do this several times. Let’s meet Watchover.
Watchtover has the ability to “watch” running Docker containers on either the same local or remote host, check if there is a newer image in the remote registry, and then update the container with the new image using the same configuration options it was instantiated with.
I give this a try, and I found that it was very easy, just a command
docker run -d \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower
And, there is a personal bonus here. I’ve been looking for an excuse to start to play around with Go, and this is the one. I think, I’ll use the excuse of update my containers as my next phase on Go learning.
Happy coding!

Sabemos que GitHub hace parte de nuestro día a día y porque, además de funcionar como un repositorio en el que podemos encontrar algo nuevo para nuestros desarrollos, es un lugar donde siempre encontraremos a alguien dispuesto a ayudarnos a solucionar un bug o un problema en nuestro código. El año pasado gracias a GitHub se solucionaron alrededor de unos 20 millones de errores y fallos.
Y así como todas las tecnologías mejoran constantemente, Github no se queda atrás y en su última actualización ha traído una nueva funcionalidad muy interesante, la cual nos permitirá personalizar de manera más profunda nuestro perfil.
Esto mediante del famoso archivo README.md, el cual como ya sabemos incluye información general del proyecto y/o más específica como:
Así mismo y como muchos lo hacemos…

Hi !
I’m a big fan of Portanier. I usually will go for a graphical interface on top of a command line option, and to manage my docker labs, Portainer is my best choice for this.
Portainer is a lightweight management UI which allows you to easily manage your different Docker environments (Docker hosts or Swarm clusters). Portainer is meant to be as simple to deploy as it is to use. It consists of a single container that can run on any Docker engine (can be deployed as Linux container or a Windows native container, supports other platforms too). Portainer allows you to manage all your Docker resources (containers, images, volumes, networks and more) ! It is compatible with the standalone Docker engine and with Docker Swarm mode.
Portainer (see references)
From time to time, we have updates for Portainer and I always make a mess doing this manually. So here is my personal cheat sheet for the next one
And the docker commands are
docker stop Portainer docker rm Portainer docker pull portainer/portainer docker run -d -p 8000:8000 -p 9000:9000 --name="Portainer" -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer
Portainer is updated and now I got just news in the home page !
Happy coding!

Hi !
If you are looking forward to test the new Microsoft Lists (see references), and you are in First Release of office Microsoft 365, there is an easy way to access to Lists. In 2 clicks, you may have access to this:
You need to select OneDrive, from the Office 365 menu, and change the [onedrive] part of the url for [lists].
Super easy !
Happy coding!

Hi!
Azure days for me and weird behavior when I was trying to enable some monitoring resources in an IoT Hub resource. In random times, I get an error similar to this one
And, it was weird because when I check the Resources providers available and registered for my subscription, the [microsoft.insights] appeared as [registered].
So, I tested a couple of reset scenarios, some other PowerShell scripts, and at the end the solution was the easiest one:
5 minutes later, my monitoring capabilities were back available for me.
Again, it happened at random times, so there maybe an external factor also in this scenario.
Happy coding!
