BrowserBox VS serenity

Is that right? Could be a recent acquire if it's DOM mirroring.

I heard CF acquired S2 a few years ago, and what S2 did is they created a WebAssembly binary that composited the browser SKIA draw instructions on the client, and streamed the SKIA draw instructions from the server. Not without its issues, but certainly useful.

What we do is just stream pixels to the client. Yes it's expensive in terms of bandwidth, relatively. But the advantage is simplicity. And with a close server and bandwidth trending faster and cheaper, with the increasing drive to video consumption across media, I don't see bandwidth as an issue.

This demo is probably not really ready for a widespread audience, but luck it I’m just posting it anyway

> Edit: parent commenter seems to be promoting their product. Looks like a random remote browser, perhaps avoid entering important credentials there.

True. Maybe I should have put a full disclosure? I thought it was obvious, but I get if it wasn't. I'm sorry for not being more clear!

It's a good point to advise people to avoid entering important credentials in something that probably looks untrusted. I'd also advise that at this stage as we have no SLAs for now, and are just testing this SaaS-to-be demo of this source-available product:

Thank you for pointing out the reasonable and important security concerns. Although I should have probably done that myself, I was just so eager to help!

Aside: I am surprised tho that you were unable to even login on your VPN. I would think that the IP blocks we run the browser form and those of a VPN would be in the same category of 'cloud IPs', so why should it work on CloudTabs but fail for you directly on a VPN? Who knows?

These are difficult problems and perhaps the modern web has developed at a pace that older tech like RDP has not kept pace with. But Guacamole bucks that trend. The video shows how far it has come.

Guacamole is good, and I love that it's clientles and works in the browsers, but VNC lacks sound so you need to do that separately. Also the input lag when remote frames increase in frequency is challenging.

If you're looking for something lighter weight and possibly smoother and faster (albeit non-free software with a non-commercial option), check out BrowserBox: https://github.com/BrowserBox/BrowserBox

Solving input lag, and maintaining responsiveness across a range of bandwidth situations has been one of our priorities and I think we've mostly achieved.

We've accomplished this through a combination of sensible heuristics for congestion control, and using WebRTC with a fallback to WebSockets when faster. We also have audio out of the box, no set up required!

However there's always room to improve, which is why it makes it so exciting to work on. Depending on how close you are to a server you may encounter lag issues, too. Check out a free live demo of it working here (sorry, signup is not supported yet!):

Some other problems we solve that are not always so easy to configure with Guacamole (and are harder to do with an RDP layer in general), but much easier for us as we virtualize the browser itself are first class mobile support.

Obviously that's an issue with remoting desktops from small form devices in general, but if a browser is all you need remotely then we got your back! :)

Same time, BrowserBox will not be for everyone. It all depends on what you need. Get on touch if you are interested!

Run your browser on a remote machine? Using say BrowserBox: https://github.com/BrowserBox/BrowserBox

Full disclaimer: my company develops it.

to "repoint", or reorient an active RDP session to instead targe the "console", a sort of persistent virtual terminal session that the computer always has. From the days of when people actually sat in front of the machines they were using. Physically, like.

I thought that if I could send my RDP session to console then it would live. It would be alive!

And it was. But the audio still died.

All the while, I was context switching out of RDP back to my macOS desktop, to check my BrowserBox connection open in a regular browser tab. Every time, no matter what weird configurations, registry settings, or supposed ways to change various settings related to RDP, nothing worked. Every time audio still died.

This was quite possible the biggest, craziest bug I ever worked on. (Interestingly enough the second biggest, craziest bug I ever worked on was also audio related).

But maybe it wasn't a bug. Maybe it just wasn't to be. Perhaps the gods willed it to be not so. None shall ever, from now until the ashes fall upon the ghost of the world, and time stands finally still, stream audio from Windows Server without a real RDP connection.

It was during this period I also discovered the idea of a Windows Session Host server with Client Access Licenses. Turns out, you need to purchase a RDP license from Windows if you want more than 2 RDP sessions (approximately) to the same OS instance/VM.

Turns out, too, that this notion was not related at all to getting audio to work.

It really seemed like I'd never get there. I was starting to think: Cut my losses, abandon it. It was a nice dream, shame it didn't work out, but that's what happens sometimes.

One day, I woke up with a hunch, that if I could someone use VNC at the same time as RDP, perhaps I could trick the repointed console session into staying alive. I didn't know how or why this should happen, but it just seemed like: it should, somehow. As if through all my intense working with Windows, it was somehow whispering to me, telling me how it wanted to be treated. As if Windows itself wanted this to occur, and somehow through all the interacting with it, I'd absorbed that message. And figured it out. I knew I was onto something with this. Momentum, and optimism, returned. I felt re-energized. I began to feel like this was possible. But still, I had no idea how to do it.

Turns out, I eventually figured it out. And made it repeatable. And further that it worked on: Windows Server 2022, Windows Server 2019. It also, IIRC, worked on Windows 10 and Windows 11.

I formalized it all into a ridiculous PowerShell script where nothing now seemed impossible (so I went so far as to even use crazy C#-in-PowerShell hacks to close windows automatically as part of the install process, just to ensure that all that epic work, 10 hour days, maybe for over two weeks or more, were not wasted. And finally I ended up with a script that actually managed to both install BrowserBox, and set up the required VNC/RDP dance needed to keep the Windows audio drivers active, even when I do not have an RDP connection.

It was kind of complex, and like synchronized swimming, depended crucially on the order of the orchestrated VNC and RDP connections, and what was done in each session, but roughly, the process the enable audio on Windows versions, went like this:

- Create an initial RDP connection to the Windows based server for setup.

- Set up the application by performing a normal install of BrowserBox

- Open up registry key settings enabling: multiple (the maximum allowed for free, which is 2) sessions; and connecting to localhost

- Also set up a login script that will perform "The Magic Task" described below.

- Install VNC, and configure it with a password. From within that RDP session, create a VNC connection from that Windows server to itself, and ensure that VNC window is open and not minimized.

- From within that loopback VNC session just created, execute the logon script (which will happen automatically) to perform the Magic Task. The Magic Task is: use tscon to repoint the current main active RDP connection (from my local computer to this remote Windows machine) to instead point at console, disconnecting me, and creating a ourobouros-double-loopback-VNC-RDP-ying-yang super session that is self-stabilizing and crucially (Crucially! because at that point it had been 3 weeks of effort!), keep the audio streaming

The music might die one day. But not today.

I managed to factor out this code into a relatively reusable-esque script that I called Thunderbird (because I was so in awe of myself at that point haha!)

Postscript

Turns out tho, despite all that effort, Windows was never a very popular target for BrowserBox. Sure, good to prove that it works there and provide a first blush at support, but in the end, not that many people use Windows to run BrowserBox. As proud as I am of that achievement, I can't even guarantee the method described still works today. The script had so many moving parts, I imagine it would be pretty fragile. Also, I have a suspicion that, as of this post today, Microsoft may hear this and want to lock down this seeming workaround because, even tho I don't think there's a way to use it to get more RDP connections that licensed, it sort of seems like something that shouldn't be possible, so I'm kind of worried they will just stamp it out.

This sucks. Supply chain is such an issue.

Even tho we don't currently target any npm releases, I make use of socket.dev to monitor my project by creating an npm release for it. But my project BrowserBox (lightweight virtualized web browser) only uses ~800 dependencies including all descendents, with only 19 top-level deps (cool your heels non-JavaScript folks, this is comparatively lightweight for a full stack boing).

I'm considering just snapshotting all 800 deps into a @browserbox namespace at npm. And then tracking any vulnerabilities discovered and patching the fixes.

It sounds crazy, but that's where we are. At least that way I "own" all the dependencies and can guarantee (up to company security at least) that we don't have supply chain vulns on the Node/JS side.

SerenityOS replicates that look and feel. It is also implemented in a dialect of C++ that adheres to some of the good parts of C++98: https://serenityos.org

One example of a useful technique

https://serenityos.org/ apparently only makes source code available. There are no binary images of the OS to install

I think Andreas said this functions like a little test -- if you're not willing to build it from source, then you probably wouldn't be a good contributor anyway.

Likewise, my shell project provides source tarballs only, right now - https://www.oilshell.org/release/0.21.0/

It is packaged in a number of places, which I appreciate. That means some other people are willing to do some work.

And they provide good feedback.

I would like it to be more widely available, but yeah I definitely see that you need to "gate" peanut gallery feedback a bit, because it takes up a lot of time.

Of course, it's a tricky balance, because you also want feedback from casual users, to make the project better.

Indeed, given the existence of `JS::NonnullGCPtr`, `JS::GcPtr` intentionally corresponds to a nullable pointer, so it seems dangerous to convert one to a reference without a null-check.

That said, a naive code search finds what *may* be more cases of this pattern:

https://github.com/search?q=repo%3ASerenityOS%2Fserenity+%2F...

Eg: https://github.com/SerenityOS/serenity/blob/a68b134e6dea5065... -> https://github.com/SerenityOS/serenity/blob/a68b134e6dea5065...

In some of those search results, it is fine because there is a preceding null-check, and obviously I know nothing about this code other than this naive search result, but perhaps it would be prudent to vet all of them.

It is a SerenityOS project. You can find the answer to that question in their primary project's FAQ[1].

The best way to write proper exception free C++ is not to use the C++ Standard Library.

I initially confused it with Serenity OS prior to watching the video: https://github.com/SerenityOS/serenity

My contributions to SerenityOS[0] helped me get my current job. My team lead (who was also my interviewer) was interested in what I did since I listed some of it in my CV, and I showed him some PRs I made and explained what went into each of them. It was really exciting because I didn't have professional experience with low-level development, and basically got the job due to hobby programming.

Definitely not "literally impossible", just a great deal of work. https://github.com/SerenityOS/serenity/tree/master/Ladybird
