#Windows10 – Fixing Mouse Without Border DPI screen settings (very easy!)

Buy Me A Coffee

Hi!

A while ago, I wrote about the awesome [Mouse without Borders] application. This app is extremely useful, and it’s becoming very handy in scenarios like the Avanade Toronto Innovation Center.

In our Innovation Center, we have plenty of different machines, and it wasn’t a good moment when I realize that this is how the App Settings looks in a Windows 10 machine with some DPI customization.

I don’t have a lot of Windows Presentation Experience, however I know that we can solve this via some configuration / manifest changes for the App. I look up for the application folder [C:\Program Files (x86)\Microsoft Garage\Mouse without Borders], and I opened the [MouseWithoutBorders.exe.manifest] file with Visual Studio Code.

Lucky for me, the section that I needed to add it was already there. It was commented, so I un-commented this, save the file and restart the application. Of course, you need elevated privileges to do this.

5 seconds later my Settings windows was finally amazing again!

Happy coding!

#Windows10 – Mouse without borders, a #MustHave if you work with 2 or more computers

Buy Me A Coffee

Hi!

Somehow, I didn’t know this one, shame on me!

If you work with 2 computers, is a must have. In example, at home I have a power gaming computer for AI and Mixed Reality. I work with 2 monitors, my ergonomic Microsoft keyboard and my Logitech MX Master 2S mouse. I perform most of the work on my main computer, however from time to time, I need to switch to my laptop.

Thanks to the Microsoft Garage team, in 10 minutes I can easily share my mouse and keyboard from my main computer to my laptop just moving the mouse between desktops. As a bonus, I can also share clipboard, and tons of other amazing features.

Official Description

Mouse without Borders is a product that makes you the captain of your computer fleet by allowing you to control up to four computers from a single mouse and keyboard. This means that with Mouse without Borders you can copy text or drag and drop files across computers.

#Windows10 – Cleaning some disk space, Windows SDK and #dotnetcore installs

Buy Me A Coffee

Hi!

I’m very careful with my disk space, however my C: drive in Windows 10 started to claim about low space. I got 3 disks on my machine, 2 SSDs and a regular one; and I always check to install all my software on my D: drive. So, that’s why running low space on C: was shocking.

So, I did a small check on the apps and contents using a lot of disk and I found 2 main sources

  • Windows 10 SDKs
  • DotNet Core SDKs and Runtimes

Every time a new version of Windows 10 is released, and I build a Windows 10 App, I get a new Windows SDK. Each one is around 2GBs, I got almost 20, so make your numbers.

Windows 10 Settings App and Features Apps sizes

Note: There is a cool feature to find usage space of installed apps by this, out of the box in Windows Settings.

The second one was related to .Net Core. I had a lot of versions installed, and every time I get a new update on Visual Studio 2019, it seems that I’m updating also my .Net Core SDKs. Right now, I only care about .Net Core 3, so it was time to uninstall all the others.

The official documentation ” How to remove the .NET Core Runtime and SDK” (see references) wasn’t very helpful. However, it was a good source to learn more about dotnet command, specially this one:

C:\> dotnet --list-sdks

This command list all the installed SDKs, and with a little of PowerShell scripting I manage to uninstall almost everything. Once I started this path, I also realize that the

$app.Uninstall()

command was not working, so a little search pointed me into an old article from Scott Hanselman, where he did a similar script to remove old .Net Core versions (see references).

The final script is

You can also get the ps1 file directly from GitHub here https://github.com/elbruno/Blog/tree/master/20191016%20Uninstall%20NetCore%20Versions

And a warning, the script will list all the installed dotnet sdks

And then, when the uninstall process start, we will require to confirm each uninstall action. Not very user friendly, but it get the work done!

Final advice is to repair the .Net Core 3 version, just in case something is missing.

Happy coding!

#Microsoft – Insider Programs at Microsoft (thanks to @shanselman!)

Hi!

3 years ago, I wrote a post where I listed some of the Insider Programs at Microsoft.

Microsoft – List of almost all #Insider Programs (the ones I know …)

This was on 2016 November, and I added in the list Windows Insider, Office Insider, Visual Studio Insider, the almost dead Skype Insider and more.

Now thanks to Scott Hanselman (@shanselman) I found an official resource with all the Insider Programs at Microsoft.

Insider Programs at Microsoft

Up to today, we can find Bing, Edge, Office, Skype (still!), Visual Studio, Visual Studio Code, Windows and Xbox. Super cool!

Happy coding!

#Python – How to create a Virtual Environment in #Windows10 (Easy one, and brain backup!)

Hi!

Quick post today, and mostly a reminder on how to create a Virtual Environment in Python in Windows 10. I’ve been doing this mostly in my Mac and my Raspberry Pi, and I always forget how to do this on Windows, so … I’ll write this post to have this

Install Python3.

Download the installers from the official Python source (see references). I usually install it on the root of my C: hard drive and name it with the version. In example: c:\Python37_64 folder.

Remember to also add this folder and the Scripts folder to the Environment Variables.

Note: Once you start to install tools which uses Python, your OS becomes a nightmare. You will have your own installed python, the version installed with Visual Studio, the one with Visual Studio Code, another one for Anaconda.

I’m not sure if this is a best practice or not, but I usually remove all the other versions and keep mines in the root of the C: drive.

Ok, let’s go on.

For a new virtual environment named “testEnv”, open a command prompt and navigate to the python folder. Then run the command

python -m virtualenv testEnv

After a couple of seconds, the virtual Environment will be installed, and you can use it by run the [activate.bat] script. In this example

  • The virtual environment will be created at [c:\Python37_64\testEnv]
  • The virtual environment activate script will be at [c:\Python37_64\testEnv\Scripts\activate.bat]

So the full command sequence is similar to this one

Now you have your virtual environment up and running and you may want to start to add your own packages or tools. Like in example: Numpy or to list the installed packages

Finally, you may leave the virtual environment with the command

deactivate

Happy Coding!

#Personal – Amazing surprises managing the internet traffic at home #RaspberryPi #PiHole #Windows10

Hi !

A couple of days ago, my friend Luca (@lucavgobbi) told me about PiHole: A Network-wide Ad Blocking. Even better, let me copy the official description from their GitHub repo:

The Pi-hole® is a DNS sinkhole that protects your devices from unwanted content, without installing any client-side software.

Easy-to-install: our versatile installer walks you through the process, and takes less than ten minutes

Resolute: content is blocked in non-browser locations, such as ad-laden mobile apps and smart TVs

Responsive: seamlessly speeds up the feel of everyday browsing by caching DNS queries

Lightweight: runs smoothly with minimal hardware and software requirements

Robust: a command line interface that is quality assured for interoperability

Insightful: a beautiful responsive Web Interface dashboard to view and control your Pi-hole

Versatile: can optionally function as a DHCP server, ensuring all your devices are protected automatically

Scalable: capable of handling hundreds of millions of queries when installed on server-grade hardware

Modern: blocks ads over both IPv4 and IPv6

Free: open source software which helps ensure you are the sole person in control of your privacy

I setup this in an extra Raspberry Pi 3 that I have at home, and keep it running for the last couple of days. I was in shock when I realized that aprox 30% of my internet traffic is … not so good.

PiHole dashboard

One of the cool features of PiHole, os that you can work with their logs. So I decided to apply some very powerful Machine Learning algorithms to detects anomalies and strange behaviors.

In the meantime, I decided to read the logs, and make some filters just using Excel. And I found a lot of very strange urls. Today I’ll share some of the Microsoft ones.

So, in example, do you know what does this set of urls have in common?

  • location-inference-westus.cloudapp.net
  • licensing.mp.microsoft.com
  • watson.telemetry.microsoft.com

They are all Microsoft endpoints ! It seems that Windows 10 is sending a lot of diagnostic and other type of data. Lucky for us, most of this endpoints are well explained for each one of the Windows 10 versions. So, in example, I don’t use a lot of UWP apps, and it seems to me that the localization service does not need to send a lot of information, from a FIXED PC.

I decided to add some of this domains to the blacklist of domains and so far, so good. Windows is still working amazing, I enabled some of the urls so I can use also Visual Studio and Azure DevOps, and my user experience is still the same (with 30% less of traffic!)

So, I may want to also write about some domains I found other chatty devices uses like my Amazon Alexa, my Roku, and more … maybe in the next post! And kudos to the PiHole team!

Happy Coding!

#MacOS – Not so good with Screen Resolutions and “even better” at projection mode

Hi !

The first time I was doing a demo and connecting my MacBook Pro to a projector, I found out that the screen settings and configuration in a MacOS are completely different to the usual Windows experience. And, IMHO, not in a good way.

In Windows, when you are working with 2 or more screens (monitors / projectors) you have the chance to define specific settings for each one. This settings include orientation, resolution, and more.

MacOS display runs at its native resolution, which is the best resolution designed for the display. To change the resolution, you need to open System Preferences and select displays. Then in the [Display section], we can change the resolutions by selecting the [Scaled] option.

So far, so good. Each option also shows a “Looks like resolution …” options which is great. But, not good enough. Before a demo for a client or a user group, I like to dry run my presentations and demos using a custom resolution. You never know, which hardware is going to be at your final destination.

After testing a couple of apps, I finally found a very good one with the features I need:

Disable Monitor, https://github.com/Eun/DisableMonitor

Disable Monitor allows me to quickly change any screen resolution with 2 clicks; it also lock the screens and detect monitors.

Simple and easy. Happy coding!

#Windows10 – Windows #VisionSkills sample UWP App

Hi!

Yesterday the Windows Team announced the preview version of Windows Vision Skills. So today I was browsing the samples in Github and I’ve created a simplified version of the Skeleton tracker using a live feed from a webcam.

Here are some notes about my GitHub sample

  • The UWP App must be Windows 10 version 1809
  • I added the NuGet packages [Microsoft.AI.Skills.Vision.SkeletalDetectorPreview] and [Microsoft.Toolkit.Uwp.UI.Controls]
  • The MainView uses the CameraPreview control from the [Microsoft.Toolkit.Uwp.UI.Controls] toolkit.
  • Each frame is processed and I use a SkeletalBinding to detect Skeletons / bodies
  • The core detection is performed here
        private async Task RunSkillAsync(VideoFrame frame, bool isStream)
        {
            m_evalPerfStopwatch.Restart();

            // Update input image and run the skill against it
            await m_skeletalDetectorBinding.SetInputImageAsync(frame);
            await m_skeletalDetectorSkill.EvaluateAsync(m_skeletalDetectorBinding);

            m_evalPerfStopwatch.Stop();
            m_skeletalDetectionRunTime = m_evalPerfStopwatch.ElapsedMilliseconds;

            await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
            {
                m_bodyRenderer.Update(m_skeletalDetectorBinding.Bodies, !isStream);
                m_bodyRenderer.IsVisible = true;
                UISkillOutputDetails.Text = $"Found {m_skeletalDetectorBinding.Bodies.Count} bodies (took {m_skeletalDetectionRunTime} ms)";
            });
        }
  • There is also a BodyRenderer.cs class used to draw the skeletons on top of the CameraPreview Image control. It draws lines in an empty canvas.

You can download the sample code from here https://github.com/elbruno/Blog/tree/master/20190501%20VisionSkills%20Skeleton%20Sample

#Windows10 – Windows Vision Skills (Preview), an amazing set of AI APIs to run in the edge!

Hi!

Today’s announcement is a big one if you are interested on move AI capabilities to the Edge. The Windows team make public the preview of Windows Vision Skills framework:

Windows Vision Skills framework is meant to standardize the way AI and CV is put to use within a WinRT application running on the edge. It aims to abstract away the complexity of AI and CV techniques by simply defining the concept of skills which are modular pieces of code that process input and produce output. The implementation that contains the complex details is encapsulated by an extensible WinRT API that inherits the base class present in this namespace, which leverages built-in Windows primitives which in-turn eases interop with built-in acceleration frameworks or external 3rd party ones.

The official blog explain the basic features of the framework and describes a set of scenarios like Object Detector, Skeletal Detector, and Emotion Recognizer.

We have UWP Apps in the repo samples, and it only took 1 min to setup everything to get the App up and running. In the following image, it smoothly detects a person and a chair.

The next image is the sample for Skeletal detector (as a old Kinect dev, this really makes me happy!)

This is an big announcement, because all of this APIs are native , and that means we can easily use them in

#AI – Mis posts sobre CustomVision.ai, exportando y utilizando ONNX, Docker, en PC, RaspberryPi, MacOS y más !

Buenas !

Ahora que tengo una pausa entre eventos en Canada y USA, y ya he escrito varios posts al respecto, es el tiempo ideal para compilar y compartir los posts que he escrito sobre CustomVision.ai. Sobre como crear un proyecto de reconocimiento de objectos, como utilizar el mismo en modo web, invocando un HTTP Endpoint desde una app de consola. Y también desde aplicaciones en Windows 10 exportando el proyecto a formato ONNX y utilizando Windows ML. Finalmente, un par de post donde explico como utilizar CV.ai con docker en PC, Mac y Raspberry Pi.

  1. Object recognition with Custom Vision and ONNX in Windows applications using WinML
  2. Object recognition with Custom Vision and ONNX in Windows applications using WinML
  3. Object recognition with Custom Vision and ONNX in Windows applications using Windows ML, drawing frames
  4. Object recognition with Custom Vision and ONNX in Windows applications using Windows ML, calculate FPS
  5. Can’t install Docker on Windows 10 Home, need Pro or Enterprise
  6. Running a Custom Vision project in a local Docker Container
  7. Analyzing images in a Console App using a Custom Vision project in a Docker Container
  8. Analyzing images using PostMan from a Custom Vision project hosted in a Docker Container
  9. Building the CustomVision.ai project in Docker in a RaspberryPi
  10. Container dies immediately upon successful start in a RaspberryPi. Of course, it’s all about TensorFlow dependencies
  11. About ports, IPs and more to access a container hosted in a Raspberry Pi
  12. Average response times using a CustomVision.ai docker container in a RaspberryPi and a PC

Windows 10 and YOLOV2 for Object Detection Series
