    I love the serenityos concept (and ladybird browser) so I'm glad to see this progress!
    • LeFantome a day ago |
      Me as well.

      Sadly, they have parted ways at this point. Not only has Ladybird broken off into an independent project but it does not consider SerenityOS a target platform anymore.

      Ladybird is slowly shedding a lot of the “home grown” Serenity layers and replacing them with more mainstream alternatives.

      As I am primarily a Linux user, I am excited to see Ladybird become a real alternative on Linux. However, as a fan of SerenityOS as well, I am sad to see all the energy and innovation that was going into Ladybird get stripped out of SerenityOS.

      • leidenfrost a day ago |
        I just with it retains the "hobby project with real programming practices first" vibe and not get carried away with the anxiety to compete with big Browsers.

        Yes, I too want a third browser alternative. But if they sacrifice code quality for getting there fast, it will end up with the same fate as Firefox.

        • TehCorwiz 21 hours ago |
          It's not quality they're sacrificing. SerenityOS is built on the idea of rejecting anything "not invented here". Basically it's from-scratch on purpose. Ladybird by contrast actually has the goal of being a real usable viable independent browser. So they're removing a lot of the home-grown Serenity stuff and replacing with open source libs. For instance they just removed the their home-grown SSL implementation and replaced it with OpenSSL. Likewise with their graphics layer they adopted a mature backend which now supports WebGL as a results. Ladybird's network stack is based on Curl these days I believe. It's about using solid public open source libraries as the foundation instead of having to be experts in every niche part.
        • fngjdflmdflg 21 hours ago |
          They are vastly improving code quality by replacing first party libraries with third party ones. For example all the encryption libraries, media codecs etc. create a needlessly large attack surface (and general correctness surface) if you roll your own. That's why some of the first things they've started using are FFMPEG and OpenSSL.
      • bowsamic 21 hours ago |
        Ladybird has a very large political aim: to become the only browser that isn't funded by Google or based on Google's browser engine. The reason it left behind SerenityOS is because it has moved from a hobbyist aim to a very serious political aim.

                      So? It’s not as if Apple wouldn’t have plenty of other ways to fund WebKit development otherwise.
                      • bowsamic 8 hours ago |
                        Sure but would they? Currently they get it totally for free. If they had to finance the development themselves then it would get real hard to justify real quick. $20bn is a lot of money even for Apple

                        It's not about whether or not Apple have the resources to make their own browser engine, it's about whether it makes sense from a business point of view to make their own browser engine. Currently it does, because Google pay them huge amounts of money to do so. But what business case would there be to pay that $20bn themselves if Google did not fund them? Would it be worth that just to avoid Chromium?

                        • spencerflem 4 hours ago |
                          Tbf - they don't pay for WebKit, they pay to be the default search engine. If Apple wanted, they could switch to Chromium and still have the same captive audience and bargaining power (but a lot less control of the direction web standards go)
                        • Apocryphon 4 hours ago |
                          This is insipid. Why would Apple adopt a fork of WebKit when they’ve been using WebKit just fine for so long? Why would Apple of all companies defer to something in Google’s realm besides search? Do you have a single technical justification for Apple to overturn decades of WebKit use that’s baked into its frameworks and its control over iOS to use Blink?

            i'm not sure why you are being downvoted -- i can see angle as just a platform compatibility layer (in the same category as qt, which ladybird also uses), but skia (vector graphics) is definitely an important part of a rendering engine, which, coupled with the insane complexity of skia's implementation, does appear to jeopardize the whole 'web rendering engine from scratch' aim.

        Stuffing bytes through a faux serial port with rate limiting, or mangling the result into text? Those actually bother me less; they're kinda ugly, but in my mind they don't compare to cutting through all the nice abstractions and shoving raw bytes down a hardware port on a running Linux system.
    • imperialdrive a day ago |
      Very curious what that would represent, to a layman.
      • _joel a day ago |
        Seems it's seeking to the the first ($1) argument in /dev/port file and writing in stuff from the second argument ($2) with some hex/decimal magic. It's pretty hacky, but if it works, it works.
        • sedatk a day ago |
          Seek operation may be working like "function selection" on that specific device driver. The hex encoding of the seek offset gave me such vibes.
          • lpribis 19 hours ago |
            Writing to seek ofset N of /dev/port puts the written byte out on port N. There are 256 possible IO ports in x86 which afaik can be mapped arbitrarily by manufacturers. The hex encoding (using bash math eval syntax) is just for their convenience, so they can write `./outb 80 X` instead of `./outb 0x80 X`, as dd takes decimal parameters, not hex.
            • skissane 15 hours ago |
              > There are 256 possible IO ports in x86

              65,536 IO ports not 256. Not counting memory mapped IO ports whose number is only limited by the physical address space

              > which afaik can be mapped arbitrarily by manufacturers

              Pretty much, but some of the assignments IBM picked for the original IBM PC are a de facto standard. However, as newer machines lose more and more legacy peripherals and controllers, fewer and fewer of those original ports still exist. Thats said, the article mentions using the POST port (0x80) which is one of those original port numbers.

              • hakfoo 13 hours ago |
                While you can theoretically talk to 65,536 ports, a lot of old hardware only wired up the lowest 10 or so bits of the address space. So the parallel port at 0x378 might also be accessible at 0x1378, 2378... F378.

    • mysterydip a day ago |
      > Device drivers are a huge obstacle for any fledgling OS.

      I've wondered if new/hobby OSes would fare better by starting out targeting a popular single board computer like a raspberry pi? A mostly fixed set of hardware to make/get drivers for and test your system on.

      • yjftsjthsd-h a day ago |

              I don't know where this idea that the RPi has good hardware documentation comes from. One glaring example is its DWC USB controller. Sure, it has a Linux driver that is open source, but its datasheet is not publicly available!

              So if you want to develop your own driver for it, you have to second guess its documentation by reading at the driver's comments. This is bad.

            • mardifoufs 18 hours ago |
              What do you mean by documented? Sure we have a general idea of how stuff works, and some implementations can even serve as a reference but almost nothing is documented in an official sense. Your average Chinese SBC is much, much better documented, in the sense that the SOCs are at least officially documented. The Broadcom soc isn't.
          • jazzyjackson a day ago |
            Well unless they want to target PowerPC and make interested parties buy a Raptor Talos workstation what else is open enough for you? (Actually I would support this) Are there RISCV systems that are blobless?

            And yet there is a wide variety of operating systems available for the RPi, so it doesn't seem to be too much of a hurdle in practice.

              As a maintainer of one of these OSes that runs on the pi (though not the person that did the port): no, it's a pretty big issue.
              • tssva 5 hours ago |
                What issues did the proprietary blobs cause versus porting to other arm based SBCs without them?
                • ori_b 10 minutes ago |
                  It's not so much the proprietary blobs, as the complete lack of documentation and debuggability for the peripherals. The PC platform, and several other SBCs, are either well documented, or at least give you the possibility of obtaining hardware with documentation.

                  That, combined with general flakiness (eg, power delivery issues for peripherals on older pis), and you end up with users blaming the software for hardware issues.

                  It's just not very fun to develop an OS for.

          • fngjdflmdflg 21 hours ago |
            I think the replies to this post may be missing the point? AIUI The raspi CPU drivers being closed makes it actually pretty hard to write an open driver for it. So you would need raspberry pi or their CPU supplier to write the driver for you, which they wouldn't do for a small OS. It took multiple years to support raspi 4 in mainline Linux and AFAIK raspi 5 still does not have a fully functioning mainline driver. That's why Raspberry Pi OS exists. You would pick a CPU that has open drivers because it would be easier to write your own for a different operating system.
      • tssva 21 hours ago |
        I think the path Serenity took is the better one. Initially targeting QEMU as the single supported platform. You have the same advantage as far as targeting a single platform for drivers but contributors don't need to buy additional hardware, can develop using the platform/tools they are accustomed to, starting instances is faster than rebooting hardware and no need to deal with the issues of remotely debugging. Targeting a specific SBC as a 2nd platform after a certain level of stability is reached is probably a good idea.
      • junon 20 hours ago |
        That implies AArch64 support which many hobby OSes don't have, usually because the introductory osdev material is written largely for x86.

        But yes, raspi is a good platform if you are targeting arm.

        As I'm also designing an OS, my biggest piece of advice for anyone seriously considering it is to target two archs at once, in parallel. Then adding a third becomes much easier.

        • kelnos 19 hours ago |
          Raspberry Pi has a bizarre boot sequence and bringup process, much of it which is not open and not implemented in open source code. I think it's probably not a great platform for this sort of thing, despite it being decently well-documented.

          (And even then, its USB controller, for example, has no publicly-available datasheet. If you want to write your own driver for it, you have to read the Linux driver source and adapt it for your needs.)

          • jazzyjackson 14 hours ago |
            For anyone that hasn't fallen into this rabbit hole yet it's a good one: raspberry pi started out as a kind of digital billboard appliance, so they chose a GPU with efficient 1080p decoding and strapped a CPU to the die. On power up the (proprietary) GPU boots first and then brings up the CPU.

            That's as far as I got before discovering the Armbian project could handle all that for me. Coincidentally that's also when I discovered QEMU because 512MB was no longer enough to pip install pycrypto once they switched to Rust and cargo. My pip install that worked fine with earlier versions suddenly started crashing due to running out of memory, so I got to use Armbians faculties for creating a disk image by building everything on the target architecture via QEMU. Pretty slick. This was for an Orange Pi.

      • LeFantome 19 hours ago |
        QEMU is a fixed set of hardware. And far easier to target than a Pi.

        The founder of SerenityOS created it as therapy and a pure “happiness” project. I am not sure actually using it was a real goal. So, he did the stuff he found interesting. That led him to writing display servers and web engines and crypto libraries and away from “real” drivers. He wrote his own C/C++ standard libraries and userland utilities but only enough driver code to make QEMU happy. It only ever ran in a VM on his Linux desktop. In the end, he found the web browser more interesting than the OS it was created for.

        Very different project from Linux where what Linus wanted was an OS for his own computer. Linus was happy to leave the userland to others and still sticks to the kernel even now.

          > In the end, he found the web browser more interesting than the OS it was created for.

          To be fair, his career was heavily focused on browser development before he ended up in a period of unemployment (I can't recall the exact circumstances), at which point he developed SerenityOS as a means of meditation/to give him purpose.

          He still works on the OS, he's just more fulfilled working in a realm he specializes in and has pivoted focus there.

          You can follow his monthly SerenityOS YouTube updates leading up to the Ladybird announcement for a more detailed rundown.

        > A mostly fixed set of hardware

        But it's not. Over time they've revised the SOC (processor) and gone from 32 to 64 bit capability. The latest - Pi 5 - has totally re-architected the I/O subsystem, putting most I/O functions on their RP1 chip and connecting that to the SOC using PCIE.

        And as already mentioned, the unusual boot sequence: The GPU takes control on power up and loads the initial code for the CPU.

        All of the OSs I'm aware of that run on the Pi depend on "firmware" from the Raspberry Pi folk. Looking at the files in the folder that holds this stuff, it's pretty clear that every variant of the Pi has a file that somehow characterizes it.

      One of Serenity's philosophical decisions is that as much as possible they build everything themselves from scratch. So even if NetBSD's drivers would be easy to adapt and have a compatible license they probably wouldn't go that route and would instead write their own drivers.

      The solution is to pick 1 good set of hardware (that the software authors sell themselves if possible) and build drivers for that and only that.

            The blog post is a detailed, technical account of the author's journey to get SerenityOS running on real hardware – specifically a Dell Chromebook 3100, referred to as "octopus." It covers the entire process from hardware selection, debugging challenges, to custom hardware modifications and software hacks. The project involves dealing with embedded controllers, debugging over USB-C, and using a Raspberry Pi Pico to bridge UART and SPI communication. The author documents various obstacles, including missing components on the motherboard, unconventional eMMC support, and creative workarounds to bypass hardware limitations.
        
            The tone is playful and filled with personal anecdotes, memes, and tech community references. Despite encountering numerous hardware and software issues, the author perseveres through experimentation and community support. The post reflects a deep passion for open-source development and hardware tinkering.

          Even as a pure hobby project, it has educational value. Being somewhat of a toy with simplifications and limits makes it understandable, but it's comprehensive and engaging enough to justify ongoing effort.

          > These projects misdirect talented individuals from impactful work.

          You have no evidence of that. You cannot force people to do what you consider to be impactful work. The definition of "impactful" is highly subjective.

          > What's the point, if they ultimately collapse due to the unsustainable nature of solely pleasure-driven endeavors?

          You presume it's solely about pleasure. Some people find gaining knowledge and learning to work with their own two hands pleasurable. Are their endeavors transitively unsustainable because of this?

          > that vital open-source projects, crucial for real-world applications, are struggling to survive due to critical lack of contributors

          The work to produce vital and crucial things should be paid. It's particularly frustrating to see people expect to not only demand they control the work of others but that they also do so without having to pay a single cent.

          > It's infuriating to witness this neglect.

          On the contrary, this project creates tremendous value for society because it is a way for people to upskill significantly in areas that would otherwise be very hard to get into. OS development is a domain where it is very hard to gain experience. The big professional OSes have high quality bars and big codebases, making contributing hard and tedious. OS dev without a community of likeminded motivated people that share their experiences is even harder.

          My most impactful project was the one that I coded quickly in three hours for fun. It has later turned into the greatest Turkish social platform in the world, is still being used by millions of people every day 26 years after I coded it.

          I'm glad that you weren't there as the self-proclaimed arbiter of real impact™ when I started writing it. :)

            So? I achieved things of my own as well, some of which I'm very proud of, but I don't go online belittling others acting as "holier than thou" to bring my point across, which you apparently do, I doubt you are as important as you claim to be.

              I didn't claim I was important. I might as well be lucky. But, assuming that you're in a position of authority to call people's work a "waste", "neglectful", and calling me "holier than thou" at the same time? Even irony has its limits.

              Let me get back to the topic and give you another example that you might relate more: "just a hobby, won't be big and professional like gnu". If Linus Torvalds had taken his own thoughts on the impact of his work seriously and decided to pursue other "more impactful" whatever he saw at the time as you suggested instead of this pleasure-driven endeavor, Linux would have never happened.

          If they are so vital, they should be paid. Those projects are struggling because big tech monopolists and the foundations they control want them to struggle.

          The Linux foundation is cutting the budget that they spent on Linux every year both in relative and absolute numbers, currently being at just 2%. Mozilla refuses to allow people to donate money towards browser development and continues to waste money on side-projects.

          Then it would be just another Linux distro of which there are 100s already.

          SerenityOS has a clear goal as a hobbyist from-scratch OS with a monolithic code-base where the entire source code is contained within a single Mono repo where the entire Software is built with the same programming language and tool chain and the entire OS and core Apps can be changed from a single repo without needing to rely on 3rd Party upstream packages. This is a great environment to rapidly prototype new UI features, like it was the first time I saw an OS able to open UI folders and Applications from `ls` output in a terminal.

          It's great that an OS with a cohesive code-base like this exists, but it's only targeted for the hobbyist developers building the OS to use and has no plans on becoming an OS for mainstream adoption.

            > Then it would be just another Linux distro of which there are 100s already.

            No, it would be a Wayland compositor, which could be made to run on Linux or the BSDs.

            > This is a great environment to rapidly prototype new UI features, like it was the first time I saw an OS able to open UI folders and Applications from `ls` output in a terminal.

            There's nothing special about this, Enlightenment did it on Linux many years before Serenity even existed.

            > but it's only targeted for the hobbyist developers building the OS to use and has no plans on becoming an OS for mainstream adoption.

            It's such a shame because it could be a great Wayland compositor, and the features you mention could be made to work as a desktop environment.

            Why spend years reinventing the wheel when others already did the hard work that they won't be able to replicate in the first place?

            It's their time, sure. And they can do wherever they want but it's still wasted effort, whether people admit it or not.

            Not even the BSDs are able to compete with Linux on driver's support, what makes people think SerenityOS could?

            I also hardly doubt the SerenityOS people don't have any expectations to get at least some adoption, they're wasting their time with their current strategy.

              You clearly haven't spend any time learning about the SerenityOS project and don't seem to have any clue about why Andreas started SerenityOS in the first place since your suggestions completely contradict why it was created.

              Why are you suggesting using 3rd Party software when the entire purpose of SerenityOS is to not use any external software and build everything from scratch? The goal isn't to save time by reusing existing software, of course they know that using existing software would save time recreating it, but that was never the point. They're creating an entirely new OS from the ground up.

              Andreas has created 100s of hours of YouTube content showing building different parts of SerenityOS, which IMO is one of the best resources for showing how to build different parts of an OS from scratch [1].

              > I also hardly doubt the SerenityOS people don't have any expectations to get at least some adoption, they're wasting their time with their current strategy.

              Since you don't seem to know anything about SerenityOS your doubts and thoughts of its developers are meaningless, the goals and purpose of SerenityOS have been well documented. It was never meant to be an OS for mainstream adoption, just an OS by hackers for hackers. They've built great software and a great community where everyone gets to work on whatever parts they're interested in and have fun being apart of and contributing to a shared creation of work together - that's not wasting time.

                Am I not allowed to say anything anymore? I know what SerenityOS is and what it's trying to do, I just think it's unreasonable and a waste of effort.

                Andreas himself changed his mind about reusing third party libraries in Ladybird, SerenityOS should do the same.

                  I know you don't care to read about things you comment on and like to throw uninformative recommendations about what people working on a project should do, that directly contradicts the goal of the project and why developers started hacking on it in the first place. Seriously, how do you expect your low effort backseat comments to be taken? You don't think the very capable OS developers already know that reusing existing Software takes less time than creating it? Or maybe you're missing some context on the project your commenting on, like its entire purpose for being?

                  Andreas did not change his mind about SerenityOS which is still a hobby OS project for Hackers as it has always been. He just moved on to work on Ladybird full-time to compete as a mainstream browser alternative to Blink/WebKit which has completely different goals to SerenityOS which is no longer a supported target since it incorporates 3rd Party libraries.

                    He did, how much do you want to bet that if he were to do it all over again he would go straight to the browser work and skip the OS project?

                    That's why he doesn't even talk about it anymore, he even removed it as a target in Ladybird.

                    It's clear that he got burned by his own decisions.

                    I don't care what you think about me or not, I don't hate SerenityOS and I wish that project well, but I think they should reconsider their stance on third party libraries.

        I disagree, unless you're comparing it to a barenbones implementation like Sway.

        I have shortly considered trying to port the Serenity GUI to Wayland, though, because I really like the visual style. I don't have the C++ knowledge to effectively navigate the project, though, so I let go of that idea pretty quickly.

        SerenityOS has no business running on Linux, but a fork could be pretty neat for 90s GUI lovers. IMO the Serenity UI easily beats those heavily reskinned KDE installs every time.

          Take a look at labwc, the look and feel is similar to Openbox and can be made to look retro-like.

          Xfce will also come with Wayland support in the next version or so I hear.

          I don't get the Sway comment about being barebones, it's a tiling compositor, it does what it should do.

          • jeroenhd 4 hours ago |
            Sway does what it sets out to do, and that's not a lot. That's why I consider it rather barebones. It relies on other tools to provide UI components that are standard in most normal desktop environments.

    • saidinesh5 13 hours ago |
      Honestly, step 1 is just understanding what the purpose of each component is.. OS, driver, device etc...

      for eg. A device driver is about exposing an interface for other programs being run on your computer, to access and control a device...

      https://m.youtube.com/watch?v=juGNPLdjLH4 this is a decent crash course on that.

      You can create a toy USB device using an Arduino or something that can send / receive information to your PC. Eg: https://m.youtube.com/watch?v=yTc2GLXfCOY .

      Then it's a matter of just understanding what the subsystem you're interested in writing drivers for your OS does, how to make it do something, just write code. Storage devices, graphics devices, etc...

      A raspberry pi can be a decent starting point for these experiments too.. eg. Writing a bare metal operating system for the raspberry pi https://github.com/babbleberry/rpi4-osdev

      I started with LDD [1], which is a book from a decade ago, but should still be relevant these days.

      I did an OS dev course in uni, that was some 15 years ago. We used Minix, which is super cleanly written (5kloc kernel) and is covered by many textbooks (sorry but can't remember which one I used, but there's also the official one).

      I got to implement a simple server (Minix is a μkernel so that's how most drivers work) and do some kernel hacking. I read the course material in advance and didn't even attend any lectures, still got an 8/10 grade ^^

      I've also heard many good things about NetBSD and of course SerenityOS (Andreas did a lot of development on live streams).

      It is indeed easy once you know where to start.

    • ultimaweapon 7 hours ago |
      Actually it is very simple to communicate with the modern hardware (both x86 and ARM). All you need to do is read/write the hardware memory. This called Memory-mapped I/O (or MMIO in short). Of course you cannot do this from the application that run on the OS since it is a job of the kernel to prevent the application to direct access the hardware memory. Here are the roughly steps if you want to get into this field:

      1. You need a programming language that capable of output the machine code for your target CPU. Better to be a language that does not have GC or runtime like Rust/C++/C/Zig. If you are not familiar with low-level language I recommend C as a first step since it is easy to find examples on the internet.

      2. Learn the basic of assembly language of your target CPU. You need this because the above language may not provide the intrinsic functions for some instructions.

      3. Start writing a hello world kernel. You can find a bunch of tutorial on the internet, especially for x86.

      4. With step 3 you should already learned how the CPU start your kernel and how many mode and privilege level available on the CPU. Usually the CPU will give you the highest privilege level when jumping into your code.

      5. Now you need to setup the CPU into whatever you want. For example, you likely need to switch the CPU to long mode on x86 so you can use 64-bits instructions. In this step you likely need to setup a virtual memory. You can find a reference for your CPU from their website.

      6. If you have reached this step then congratulations! You should already have some idea how the CPU is working with the OS and how to enumerate available devices to discover its memory location. There are a ton of works that need to be done once you are here like implementing filesystem, scheduler, etc.

      Remember that the only different between the software that run on the OS and the OS kernel is mode of the CPU currently executing its code. With highest privilege level you can use some instructions that are not available to the normal application.

    Depthcharge (the bootloader) also supports net boot via tftp. You would need to build it yourself and flash it to the SPI. It's a great feature when iterating on the kernel.
