I have good experience with https://wails.io. It uses a Go backend and a JavaScript frontend with Go functions exposed to the JavaScript side, and events with senders and listeners on both sides. All without the enormous bloat of Electron.
On the JavaScript side you can use whatever you like: plain JavaScript, react, vue, svelte, … whatever you’re familiar with.
And it can cross compile to Windows, Mac and Linux, so all major platforms covered.
Be careful with this. A DDOS will not only affect your own website but also the infrastructure around it. Your ISP’s servers and routers will be impacted, and it may cost them a lot of money to deal with your test DDOS. It will also affect other customers of that ISP and other people on the Internet. Be sure to get written permission.
Dutch citizens usually don't need a visa to travel to the US (they have to get an ESTA visa waiver instead), but if they have traveled to certain countries (in my case Sudan) they do need a visa.
The rules are more complex than can be answered based on a simple citizenship+destination question.
Now that in some countries (Belgium) more than 50% of the internet connections get IPv6 hopefully the rest will follow. It would be about time after two decades :)
What this probably leads to is scientists losing their jobs or their willingness to work in the US. Under the current president their only option seems to be to move to another country where they can do their work and discuss their findings in public. Science with a political filter is no longer science but only politics with the illusion of factual justification...
A good education shows the right data has been put into your brain. A good portfolio shows you can produce good output. I think/hope employers value the latter.
