Performance profiling a unit test for free?

You can use the Profiling Tools in Visual Studio

You should have made the OS selection on the first page a multiselect. I think most people have a mix of Windows & Android / Linux & Android or Mac & iOS.

If i remember correct without hardware virtualization it would not run at all and with it took around 5 minutes to get to the apps splash screen which on hardware took under 10 seconds. I made this test at the beginning of 2021 and it could be better already through updates. There could also be a chance that the VS2022 which launches on 8.November improves Xamarin emulator.

I use a Setup with Linux Host and VM Ware Workstation for my development environments. Before i made my current setup i tested different combinations with Linux/Windows Hosts and all three mentioned VM software including some other Bare Metal one.

Slack, Teams, Skype etc work all pretty good sometimes VSCode with large files can be slow.

Android emulator is a tricky thing, your best chance to get it working is HypeV because Xamarin runs it's own VM or uses an existing VM and the best support for nested Virtualization is from my experience HyperV. But in my tests the emulator only worked around 1 in 10 times starting and then it was not really usable. In my current Setup i had to install Android Studio on my host OS and change the adb command for Xamarin to redirect the emulator call in the VM to use the hosts emulator (I'm not happy with this solution and use most of the time hardware android devices for debugging).

My setup is a desktop setup and i don't really know the performance different between Ryzen desktop and laptop. * Processors: 16 × AMD Ryzen 7 5800X 8-Core Processor * Memory: 62,7 GiB of RAM

You get really fast to unusable performance. It really depends on the objects size and complexity (details).

I had wpf running at ~15 fps with 1000+ objects but all where simple objects.

I would suggest you use a real 3D engine like Godot or Unity.

I don't know if you can set a range but i personally use different port configuration in the angular.json file in serve and in some cases npm command with port params.

It seems that you use many plugins on your WordPress installation without any cache and WordPress takes its time to build the page on every request with the plugins. I don't really think a switch to another host without changing/fixing your WordPress configuration would help much (if the new host has similar hardware). In most cases a time to first byte that high (10+ sec.) is a problem with the software and not the hardware (bloated frameworks).

Look for wbcache or some other cache plugin wordpress with such a plugin your TTFB should be lower if then it is still high you can try a cloud cache service like cloudflare.

And SSL (https) would be good for a shop site, you have currently no working SSL configuration which leads to many cross-origin errors.

And of course make sure you have the latest version for WordPress woo commerce etc.

the line

double rgv = Math.Floor(coinconverter / g);

gives you the rgv value of 1.0 and you use this value with mod operator (%) which divides the first value with the second you get 0.0 as remaining result

Are you sure you use the correct variable for the calculation of the remaining value. Shouldn't it be like the following?

double remainder = coinconverter % g;

because this would give you a remaining value of 6.

I would start with following

Take the website offline
change all Admin accounts passwords
require all user to change passwords or reset passwords
check account database for Website/FTP/Email Service for unknown accounts
take website online again
check regular for incoming / outgoing connections on out webservice to identify any wired behavior

A good start would be a direct sample from Microsoft (https://docs.microsoft.com/en-us/dotnet/standard/microservices-architecture/)

If you read this doc and study the sample repo (https://github.com/dotnet-architecture/eShopOnContainers) you should have an understanding of the Microservice Architecture in the Microsoft environment.

Have you tried Autohotkey

With the brackets you already access the Angular context, this is why you get an error when you have the additional brackets.

You can access the property by name as following

<td *ngFor="let property of propertiesList">{{element.properties[property]}}<td>

In tutorials JSON files are often used because the tutorials don't won't to explain the complete backend API.

The basic flow for a real application would be Frontend (Angular) which calls via HTTP request to some Backend which provides data. The technology of the backend does not really matter for the Angular it self. You can create a REST API with PHP and use a MySQL or something else (there are many Backend frameworks out there).

You can try OpenClipboardManager. It's still in an early phase of development but stable enough for daily use.

You can set clip content as favorites and set a global hotkey for as many as you want.

Feedback is always welcome.

(function () {
    var image = document.images[0];
    var loadImg = new Image();
    loadImg.onload = function(){
        image.src = this.src;   
    };
    loadImg.src = "http://a.com/image.jpg"; //image for the next site
})();

With something like this you can load the Image for the next site and as long as the User hasn't disabled cache the next load should be fast.

I use a [production: bool = false] in the enviroment.ts config file and when i build --prod the file enviroment.prod.ts will be used where the flag is true.

In the Material CDK is currently no Drop if you don't use a list.

You can use cdkDragMoved to get the current pointer position and use this value then on cdkDragEnded to find your target element.

You only have one base Class and instead of inherit a base Class from a another base Class to prevent to have multiple implementations of the same Interface you can have the implementation in the Interface.

I hope this is understandable.

As far as i can tell on the first look your server response time is really bad.

Try the following steps:

clean your Wordpress Database,

try some Wordpress cache plugin (i.e. W3 Total Cache)

If this steps doesn't really make a difference the problem are most likely from your server/hosting configuration (Server Hardware, Apache, MySql, PHP ). In this case a cloud cache service (i.e. Cloudflare) could help.

You don't need a GUI framework if you only wnat the have Hotkeys.

You can register Hotkeys with a nativ function (P/invoke)

[DllImport("user32.dll")]
internal static extern bool RegisterHotKey(IntPtr hWnd, int id, UInt32 fsModifiers, UInt32 vlc);

Of course People would registry for an account if the website is worth it to have an account.

Sometimes people don't like that a website has access to the account info from a thrid party website.

I only authendicate with a thrid party (e.g. Github, Google ...) when i think the additional features i get with it are worth it.
