Show HN: I built Haystack – your own google for scattered workplace knowledge
Hi all! My name is Yuval I've been a software engineer for a few years now.<p>A few weeks ago I was scrolling through confluence pages trying to
find ssh connection details to our integration machine for 40 minutes
straight, later I discovered my co-worker slack'ed me the ssh
connection string two months ago.<p>So the same weekend I started working on haystack - a search engine
for workplace apps. that enables you to search slack, confluence,
jira, teams, sharepoint, github, and email in one place.<p>I wanted it to support natural language queries so a query like: <i>"how
to connect to integ2 machine?"</i> yields:<p><pre><code> ssh -i private.pem ubuntu@ec2-integration2.eu-est-1.compute.amazonaws.com
</code></pre>
I decided that user data should be stored locally, so all logic is
completely client-sided (including the NLP model) - I don’t want
access to your internal docs, thanks.<p>I rolled it out to my co-workers a week ago and they thought it's a
hit, so I'm planning on releasing it publicly on March 2023. But if you want to try it out before then it's
available here: <a href="https://haystack.it" rel="nofollow">https://haystack.it</a>. Thanks!

Show HN: Detecting collision between 500k circles below 5ms
Heya.<p>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.<p>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.<p>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.

Show HN: Scripting language inspired by JavaScript and GLSL
I'm working on a scripting-language heavily inspired by Javascript and GLSL.
The idea is to use this for a game engine I'm working on.

Show HN: BingeTheTube: binge YouTube channels from oldest to latest
Briefly, what the app does:<p>1. Points to a reverse playlist(an actual youtube playlist) for a channel.<p>2. Ability to skip to a position in playlist from beginning.<p>3. Request any new channel you would like to have a reverse playlist for !<p>Usage eg:<p>- Using the above you can skip to say 100th video from begining in a channel
(e.g CaseeyNeistat Vlog) and keep watching on youtube app (without going back to bingethetube.com).<p>- Come back next day and resume watching from say video 120 without a lot of scrolling<p>Useful if you like to follow a creators youtube journey or old Vlogs !

Show HN: Pole Clock, a single 24h clock with multiple timezones
Hi HN! I designed this Pole Clock to be a helpful tool for people like myself who often struggle with managing their sense of time.<p>I found that analog clocks are generally easier to read and understand than digital ones, however I find the fact that every day is broken into two 12-hour rotations unintuitive. A single 24-hour rotation makes it easier to grasp where in the day you are, the bottom half representing night and the top half representing day.<p>Additionally, because the clock displays 24 hours, you can add extra hour hands on the clock for other time zones. This is especially useful if you work remotely or have friends and colleagues in different time zones. At a single glance, see where they are in their days and energy levels!<p>I hope you'll give the Pole Clock a try and find that it helps you better understand and manage your sense of time.
