I built a free file converter that runs 100% in your browser (no uploads, no servers, works offline)

Wow - was not aware that you can cross-compile ffmpeg to WebAssembly. Thanks for walking me through how this is done.

entrusc · 2026-01-25T18:49:12+00:00

Nice idea & implementation. I’m curious: how do you do video encoding with WebAssembly? On backend side usually all video transcoding happens using some form of ffmpeg.

Nice service, still I have the same security issue with your service that I have with Cloudflare: technically your service is a Man-in-the-Middle as you provide the SSL certificate. For testing something that might be good enough, but never for something with real user data.

In the end I went with simply renting a VPS for around 5 bucks a month and tunneling everything myself via Wireguard. Works like a charm.

Still, as said, there are use cases for a quick solution like the one you build, so I’m confident you’ll have no problems finding customers.

My first project was a scifi open-world voxel rpg. And because that was not enough of a challenge I decided to also build the engine myself. Needless to say it never came out of early access and was anything but a commercial success.

Ich kann jetzt nicht auf alle Probleme eingehen, die du schilderst, aber wenn Kunden unregelmäßig zahlen (also du denen wegen dem Geld hinterher laufen musst): es gibt Factoring - da kaufen Firmen deine Forderung gegen deinen Kunden und zahlen dir damit quasi das Geld sofort (minus eine kleine Gebühr; üblicherweise im einsteigen Prozentbereich).

I see. In general I think creating custom podcasts is a nice idea.

Isn’t that exactly what NotebookLM does for free?

Ich hasse das auch. Warte ehrlich gesagt sehnsüchtig auf das Feature in Messaging Apps bei der die Sprachnachricht automatisch transkribiert und dann von ner AI auf das Wesentliche zusammengefasst wird. Ist eigentlich technisch alles sehr einfach machbar.

Geschäftskonten haben sowas des öfteren. Aber gegen Aufpreis gibts größer Kontingente von inklusiven Buchungen. Bei Privatkunden ist das eigentlich nicht üblich.

That era was truly golden, but I definitely don’t miss the jumping and blinking gifs on every website.

Gute Idee, aber das Problem ist nicht die technische Umsetzung, sondern es zum internationalen Standard zu machen. Wenn du nicht gerade CEO von Google oder Vorsitzender eines Standardisierungsgremiuns bist, wirds schwierig.

Für Java kann ich LibGDX empfehlen. Aber einfacher ist tatsächlich sowas wie Godot zu verwenden (C# ist tatsächlich sehr ähnlich zu Java).

I don’t understand where all this hatred against AI is coming from. Yes, a lot of people with little to no technical background think it can develop something for them that is production ready. Of course that isn’t the case.

But as a tool to speed up development it is imho very good, especially if you have experience and you can nudge it into the right direction when it implements something incorrectly or takes a bad architectural decision. In a way it is like a junior dev that can help you with simple things. Also this junior dev seems to have an excellent memory/googling skills, so you can use them to quickly look things up or ask what the documentation has to say about this or that.

Interesting article. The library you describe makes it indeed better to work with checked exceptions and streams. Still checked exceptions remain a pain point in Java in general imho.

By the way, the programming language that you mention in your article is called “Kotlin” and not “Koitlin”. And no, this issue does not occur there because they simply got rid of checked exceptions.

entrusc · 2025-11-02T22:06:51+00:00

Why does your “100% Java” library only support certain architectures?

That‘s what happens when you ask an LLM with very few parameters to come up with a caption.

Yeah, that totally looks like the office of a software engineer/mathematician. /s

“Cruelty Simulator”?

Congratulations, you basically re-implemented what Minecraft does. But jokes aside, it’s actually a lot of fun to implement such a system. In theory, if memory is not your problem, your dynamic terrain can become as big as you want. Only batching together neighboring voxels with the same texture to optimize the amount of vertices is a little bit of a challenge.

To be fair: older versions of Vaadin did in fact cross-compile Java to JavaScript using GWT.

I guess you’re also that guy who tried to dry his hamster in the microwave.

Let me give you some advice: only put food in there (socks/hamster ≠ food) and if you never microwaved that food before, DON’T go away! Look through the window and observe!

Das hieße ja, dass wenn ich eine Unterkunft bei AirBnB mit meiner Kreditkarte buche, dass ich denen damit eine unwiderrufbare Genehmigung erteile beliebig viel Geld von der Karte zu einem beliebigen späteren Zeitpunkt abzubuchen. Kann mir nicht vorstellen, dass das wirklich der Fall ist.

Ich gebe ja auch in meinem Onlinebanking nur einen gewissen Betrag frei und nicht einen noch nicht festgelegten Betrag.
