Show HN: Block positive reinforcement from HN with uBlock https://ift.tt/2UDRtSf

Show HN: Block positive reinforcement from HN with uBlock Inspired by the nytimes post "Luddites don't want your upvotes", and presumably being a Luddite myself, I have used uBlock to block my Karma score at the top of the page. I found myself (on old account) reflexively checking my Karma score and found myself responding emotionally to it. I do not like this. Positive reinforcement can be a dangerous thing! And negative reinforcement make me feel a bit crap. I'm going to post what I think is the right thing, votes be damned! However I do see the use of downvotes for getting rid of stupid comments and spam as a good thing. I see the use of down/upvotes for political ideologies as a bad thing. SO, I simply used uBlock to permanently block "Karma" across HN topbar. Simply go to uBlock icon, press Element Picker Mode (the eyedropper), select the Karma number, and select the Create button. Done. January 2, 2023 at 09:09AM

Show HN: Banger–A Firefox extension to extend DDG's bangs https://ift.tt/5FfUGth

Show HN: Banger–A Firefox extension to extend DDG's bangs Hello HN! I made this Firefox extension to extend upon DuckDuckGo's idea of bangs (check https://ift.tt/oapFCwX if you aren't familiar with them) and also allow the use of any search engine with them. I found DuckDuckGo's bangs fascinating, but was disappointed by how little search engines inherit that feature. And on top of it, DuckDuckGo has the "!" bang that jumps to the first search result but other search engines offering bangs like Brave Search, searx, You.com don't seem to have that. I also thought that the "!" bang could be extended with the ability to jump to the first search result of a specific site, so I added the "!!" bangs in my extension that allow you to do just that (e.g. typing "!!mdn flatMap" will bring up the MDN page for flatMap). I also added a bunch of extra features like the ability to add custom bangs, ability to search in a search engine with the "site:" parameter using "!@r" (r for Reddit), or "!ddg@r" (specify any other bang as the search engine to use), and the ability to chain multiple bangs together with ";" to open them up in different tabs; it also allows you to use multiple "site:" parameters combined with the OR ("|") operator with "," (e.g. "!@r,yt"). Feel free to mix and match! Also, for those who use it, it supports sync. There's also an option to import/export any settings including custom bangs. I've also added custom handling to fix a few bangs which are usually broken such as "!archived" and "!imgops" (They require unescaped URL as part of the path. However, DDG and other search engines always escape the URL. Banger only escapes the URL if it's part of an URL parameter). I've been working on it for around 2 months now, and I'm pretty satisfied with the result so far. Let me know if you have any comments/feature suggestions/bug reports/anything else! https://ift.tt/cz6TVDP January 2, 2023 at 12:48AM

Show HN: Detecting collision between 500k circles below 5ms https://ift.tt/oFOqhGs

Show HN: Detecting collision between 500k circles below 5ms Heya. I created a flexible collision engine for broad detection in C that's also pretty fast. Personally that's my best, so I wanted to show it here. Although... still not as fast as DragonEnergy's one that supposedly handled millions of agents bouncing off each other every frame on an old i3, haha. I hope I get better at this! He set the bar pretty high for me. I was considering including some small function that tries finding the nearest entity, although I think it might be better to simply use query for that matter. Perhaps in the future I will get a good idea of how to do that more efficiently. This is not a clickbait. Although generally you also call other functions in a tick, a collision check between 500,000 circles ("circles", not "squares", because distance is checked and forces are applied based on the angle between) is done below 5ms on not really that demanding hardware. I achieve lower times than that on my budget laptop, slightly more on my PC (yeah, weird). The total time spent in a tick is 3-4 times that. https://ift.tt/EYLz4xg January 1, 2023 at 03:08PM
