UnmappedStack··on Bing is not as bad as you think
It'd be very interesting to run the same experiment except rather than on different engines, just on different versions of Google in different years. Sadly I can't really search 2005 Google anymore of course but it would be interesting nonetheless to see if it's Google in general or rather the recent "enshittification" of their results. It may be intriguing to expand to survey takers outside of Reddit to get a potentially less biased set of results, yes.

Yeahhh I like to think of it as search like it's 2015...
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
Yeah I really do need to, I'm not sure why I didn't from the start...
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
I actually did not know if these, but I definitely will implement those!
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
Woah it was because I had run out of API credits, fixed! I'll improve the error screen for that. Sorry, did not expect this traffic, it's had several thousand searches today!
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
I see, that is odd and I haven't run into that yet, thank you! I'll have a look into it and try to reproduce the issue, which browser+OS are you on?
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
That's fair enough. For the record I do intend to apply for a non-profit official entity. I would say it still has a role as opposed to Brave considering the lack of advertising though.

Sure, would've made for a chunky post title tho :P
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
Yup, it is pretty much just a better frontend for existing search. I want to build my own index and ranking algorithm in the future, but sadly it's quite resource intensive so it will depend on financial viability a bit in terms of timeframe.
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
Oh! I will make sure to fix that, thank you for the bug report!
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
That is very true, and it's not cheap to maintain. I do however really hope that donations can cover it enough, and I have plans about other ways to monetise it while remaining not-for-profit without ads or anything that affects the user.
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
Honestly I agree. This is part of what I love about the idea of Kagi. I do believe a not-for-profit alternative is needed, however if there's any for-profit model a search engine should have, it should be paid for by the user rather than the advertiser imo.
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
I do intend to support this and have actually already been asked to!
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
This is a really interesting view, but I'm not sure I agree. So many amazing projects are truly free without the goal of profit yet their maintainers still do amazing work. I feel like part of the reason this works is because often the load is split between several maintainers (of which I hope to onboard soon, and have one or two offers already from people to contribute) and also the fact it's genuinely something enjoyable to work on (of course, to the extent it's not too stressful and overworked).

As far as I'm aware, Ecosia does sell ads.
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
This is sadly probably quite true. I'm sure there are workarounds, like slightly changing it every month or two, although that would require quite heavy maintenance. Perhaps the core algorithm stays the same but some constants that decide on the weights of different things are randomised? Not too sure.

I see nilch as slightly more about being simplistic and not having many features that are unnecessary. I do share many of the values and benefits with searxng (and really love their work!), however this is also about my own specific desire for something that is clean and has very little that is unnecessary.
UnmappedStack··on Show HN: My not-for-profit search engine with no ads, no AI, & all DDG bangs
Thank you! I would definitely consider custom ddg bangs, yes. Is there any particular reason you want that rather than just all ddg's bangs like it is currently?

I'll have a look into that project, thank you. Cost is a slight issue so far, yes. There have been about 4,000 searches in the past couple days but I've slightly improved cost efficiency with caching, and I've received two small donations which do help a bit, so the hope is that donations will be able to sustain it.

Partnering with Ecosia is a really interesting idea, however I think that there may be a conflict of interest since they do aim to make money with ads, just to go towards environmental efforts rather than a corporation. They would be disadvantaged if nilch was at an advantage over their users.

I do love the wikipedia model and I hope that nilch can run similarly. Thank you again!

UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
I'm not too sure what you mean. I kinda just avoided looking at existed implementations because it's a bit more interesting to do it myself.
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Mostly just because C is a lot simpler, and in kernel dev, simplicity is everything. I've used rust for other projects but I feel like in kernel dev I would much rather use a simple and readable language than a safe language.
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Hi, I use DoomGeneric which is a portable fork of Doom. It's on a TempFS loaded from an initrd. I use doom1.wad.
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Yeah mmap is quite a stub lol, I def cheated on that. I just wanted framebuffer access, but the user heap uses sbrk internally instead of mmap anyway so I properly
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
I think the thing is, Doom was originally written __for__ DOS. Part of the cool part is porting 3rd party software to my OS that wasn't originally written for it. That was part of my reasoning at least.
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Ah sorry, PotatOS is my old project. I'll fix that, I just copied that paragraph from the old README.
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Yeah no problem. Multitasking isn't really complex - it's generally split into two categories: collaborative and preemptive. Collaborative multitasking is simply having user programs call a yield syscall which tells the kernel that it's ready to give up control of the CPU and it switches to the next task, but this is not very secure and is uncommon on newer systems. Alternately, preemptive scheduling generally has a timer which goes off regularly which automatically switches to the next task. Choosing the next task is the next part which the simplest one is round robin, where you literally just have a list of tasks and it always selects the next task and gives each task an equal amount of time. You also have SMP versions (that work for multiple cores) and also priority-based schedulers (which give certain tasks, such as system daemons, more processing time). Hopefully that extra info helped a bit!
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Yep! Works with KVM fine (at least for me).
UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
That __is__ true, Doom can run on bare metal, but that's a fairly hacky solution in many ways. Doing it properly in userspace with a LibC and conceptually POSIX syscalls require a bit more effort. It requires a list of LibC functions and POSIX utilities as well as a few OS specific implementations.

Umm that's probably the extreme end of OSDev which I likely wouldn't be able to do, at least not for a driver you can buy. Qemu's emulated GPU is documented decently and could be possible, but things like nvidia GPUs are badly documented (and until recently, the docs were fully closed source) - even Linux has issues with this (and I actually see a few other hobby OS devs who just use Linux's GPU drivers in the end). There aren't a lot of things I've marked as near impossible but writing a genuinely decent GPU driver for a common GPU isn't really something I imagine I'll ever be able to do sadly.

UnmappedStack··on Show HN: My from-scratch OS kernel that runs DOOM
Yes, quite happy with real hardware. The kernel isn't exactly straight to Doom, it boots into a shell which you can just run Doom from, but yeah lol.
