Essence – An Operating System
- crispyalmond 5y agoI like it. Reminds me of Windows 7 mixed with old google chrome because of the tabs. I'm interested to hear more about this!
- timeon 5y ago> Reminds me of Windows 7 and Vista
- hulitu 5y agoSo a toy OS like Android. You need linux to compile it. An it says nothing about the goals, what is different compared to other OSs, why would i want to use it.
- gurleen_s 5y agoNobody asked you to use it. It’s just someone sharing something cool they did. Lighten up a little.
- ungamedplayer 5y agoYou must be very attractive to maintain friends with that attitude.
- shreyshnaccount 5y agosomeone call the firefighters.
- spicybright 5y ago> So a toy OS like Android. Riiiight, a toy. Forget how it's probably the most run OS in the world from the abundance of cell phones right now.
- dusted 5y agoAlways interesting to see a non-linx os around, I guess next goals could be getting it self-hosted. Also the source code of a modest enough size that it's not impossible to actually get your head around it.
- ajklsdhfniuwehf 5y agoAre we going to ignore that thanks to Gnome, a shutdown dialog screenshot features prominently now on a OS README? :)
- gojomo 5y agoHow does this aim to be different from other OSes? What are the motivations of its creator(s) & intended users?
- mysterydip 5y agoFrom the link someone else posted: Although it's a long shot (and very optimistic), I ultimately intend it to replace Linux and Windows as a desktop operating system.
- marcellus23 5y agoWhy mention Linux and Windows but not macOS, out of curiosity?
- codetrotter 5y agoProbably because macOS don’t need replacing :^) No, my real guess is that the author is using Windows and Linux and not macOS in the first place.
- dustymcp 5y agoFunny i have the same feeling when using macOS, i just want to replace it.
- Santosh83 5y agoApple operating systems are not intended to be replaced, and design choices make it more difficult to do so than Windows or Linux.
- nonameiguess 5y agoUnless you also have the means to manufacture your own end-user devices that have feature parity with Apple devices, there is no practical way to replace MacOS. Getting non-Apple OEMs to ship your OS with their PCs is probably not happening but at least in the realm of being conceivable.

- dvirsky 5y agoInterestingly the commit history goes back 2 years and the first commit looks like it's already a somewhat working OS. All commits by one person.
- hcarvalhoalves 5y agoImpressive, this looks more feature complete than a mere toy while the source code is succinct enough to be understood.
- deaddodo 5y agoYou could sum up most hobby OSes in this manner. My main metric for when it's moved from simply hobby to a potential functional OS is a) are there additional contributors and b) does it have a USB stack. Quite a few alternative OSes check A, very-VERY few also check B. And only one, that I know of, checks B but not A.
- capableweb 5y agoSeems "essence" checks at least B, from the README of what's working: > USB: XHCI, bulk storage devices, human interface devices.
- deaddodo 5y ago> And only one, that I know of, checks B but not A. ;)
- fernly 5y agoNo docs? Don't see any, other than the readme.
- IfOnlyYouKnew 5y agoI may be missing something, but it seems they are distributing a ported/patched GCC, which is GPL-licensed, under the MIT license?

- cxr 5y agoIt's not clear where the allegation "distributing a ported/patched GCC[...] under the MIT license" even comes from. That same notice appears in the file LICENSE.md (not that it would matter much even if it didn't).
- gtirloni 5y agoThe URL should probably be changed to https://essence.handmade.network/ https://essence.handmade.network/
- deleted 5y ago[deleted]
- capableweb 5y agoWhy? The current GitLab link has tons of information and multiple screenshots. The link you're suggesting has one tiny paragraph + one screenshot.
- nerdponx 5y agoLooks nice. My question about totally new operating systems is: does any "end-user" software work on it? Can I run Python? A Bash-like shell and some approximation to GNU coreutils? Will audio output actually work? Will my monitor work at a sensible resolution? It seems like such a tremendous effort just to get to the point where anyone other than a serious OS developer can use it. I wonder if there's any way to reduce the effort required, or if that's just how things have to be.
- forgotmypw17 5y agoI think "POSIX subsystem" plus GCC and Binutils covers most of what you ask about?
- Sophistifunk 5y agoWhat's the point at all if you're just trying to get another linux?
- spicybright 5y agoTo run useful software.
- dash2 5y agoI think the question is "how is this better or different than Linux or Windows", which it aims to replace? What are its design choices? Does it introduce any new concepts? For an example, see https://fuchsia.dev/fuchsia-src/concepts https://fuchsia.dev/fuchsia-src/concepts
- HKH2 5y agoWhat's the point of rewriting the whole stack?
- deaddodo 5y agoThere's a difference between making a Unix-compatible/Unix-like (a la Redox, Minix, Linux, the BSDs, macOS, etc) and having POSIX-compatibility + interfaces (a la Haiku, Serenity, Windows + Cygwin or WSL, etc). One is just reinventing the wheel, even if it means "having useful software"; the other is attempting something new while offering tools to make porting useful OSS simpler.
- quaintdev 5y agoLooks nice. The trapezium shaped tabs are ineffecient in terms of space management, Chrome had them at beginning but eventually got rid of them.
- vinsci 5y agoFriends don't let friends write new operating systems in unsafe programming languages.
- kmbfjr 5y agoThis advice is meaningless coming from people who lack friends. And it is clear why you do not.
- nineteen999 5y agoShow us the functionally equivalent OS that you and/or your friends have written in a safe programming please?
- mrvenkman 5y agoSeems like a great hobby! I like it.
- naasking 5y agoNo technical details of the kernel or userland, ie. monolithic kernel, microkernel?
- afr0ck 5y agoI do not see any impressive innovation in its design and the OS doesn't introduce any new concepts or paradigms, which makes it, in essence, no different from regular monolithic operating systems, implementing POSIX API with regular system calls. Just a monolithic kernel crudely implementing some well known device drivers as well as already existing filesystems with a block cache, and a POSIX-based userspace with GCC and binutils. That is said, it doesn't mean this isn't an incredible piece of work, especially if written by a single author!! That is definitely a huge amount of engineering that needs some good skills and persistence. I believe it is a very rewarding experience. The product also seems to be really working fine with very impressive stuff.
