#122Right now I'm thinking about how to silence my squat rack so it doesn't bother my neighbors when I'm using my punching bag.

#123I’m working on making body doubling a more main stream approach to accomplishing everyday tasks. Body doubling is known within the ADHD community and entails performing a task in the presence of another. More details here: https://www.healthline.com/health/adhd/body-double-adhd It helps to engage motivation by using another person as the proxy. I wrote a bit about how I think it works here: https://doubleapp.xyz/blog…
Neat! I look forward to seeing more - For a long time I found myself saying absurd things like "i work better in distracting environments" or "It's easier to have a clean house with roomates to clutter it up".
What really was happening was that I respond well to body doubling. (Never diagnosed with any sort of executive functioning disorder, but I suspect that's more because I never went and got diagnosed than me lacking one).
Cool idea.

#125I’m working on equalizing commitment between employer and candidate within the hiring process to reduce time-to-fill, cost-per-hire and cost-of-vacancy metrics.
This is really interesting. What do you mean by 'equalizing commitment'?

#126I am working on implementing a more easily presentable programming language for my implementation of a multi-modal, multi-mode dependent type theory.
I have been using a barebones version with a minimal and slightly UX hostile (for most peoples standards) version as a personal programming language. There was a random comment in a thread asking if I had anything readable for others. So I started getting a github based ‘blog’ together and started porting the compiler to JavaScript (which I don’t know very well) to have some interesting examples/demonstrations of the type theory and compilation process.
I don’t think the language will be released, but maybe some people will find the theoretical or implementation presentations helpful or interesting.

#127Earlier quoted context omitted.
How big is your index and how many sites do you cover?
1 million websites, a bit above 60 million documents in the index; the crawl is a couple of hundred million but a lot of it gets filtered out for various reasons. The crawler itself is aware of 470 million URLs. I've actually had it up to 50 million before, but that was a lot noisier data with fewer keywords per document. The current 60 million is significantly "bigger" than the old 50 million. Index size is not actu…
For sure, a large index by itself doesn't mean anything. I was more curious about the size on disk and how you manage it on a single machine.
Also curious now, why you say half a 470m URLs? :)

#128Robots that build large-scale solar farms! My friend and I started working on this last year and ended up starting a company. We moved to the bay area and did YC last summer. We've been spending a lot of time on solar construction sites and did our first demo (part of the material handling system) on a site in March. Now we're working on a robotic factory + our team is up to 5 folks.

#130High level: finding the next big meme stocks (which morphed into finding any stock that could increase a lot) I was pretty late to GME, despite having been on Reddit for a good few years. I started researching what had happened, and where the conversations were taking place just trying to understand where to place myself to be a part of the next one. I ended up checking out the typical r/WallStreeBets and the other b…
How are you finding communities to track? Are you crawling and flowing links to shitty subteddits? Creating honeypot accounts to try and get spammed invites to telegram/discord groups? Are you following the different *Chan's? IRC? I had a friend that did something for crypto. He would try to map pump and dump efforts to crypto projects. Gave them codenames and followed which ones had the most successful pump and dump…
Good question!
It's a manual process of discovery. As in, I actually go out and hunt down groups talking about stocks and if it looks interesting, I'll add it into the algorithm. I'll then analyse the data over a period of a week or two and determine whether it's worth continuing. If it is, I move it to production and it'll perform as the rest do.
If a community is not publicly visible (discord, telegram, etc) I'll ask an admin if they're okay with what I'm trying to do. If it's a no, it's a no.
There are those groups that do try and force a pump and dump but I'm against using them. That's ultimately not what I'm after as I prefer organic conversation with genuine reasons to buy. Maybe the reason doesn't turn out to be true (BBBY) but that's the case with a lot of stock analysis anyway. Sometimes the reason a stock makes it to me is due to a pump and dump but there are measures taken to make sure that we're not acting on artificial metrics.
There is also a period of premarket validation which tries to measure the stocks that are deemed interesting each day, so people are (hopefully) not getting sent duds. It can happen, yesterday ADTX only managed 0.58% but moments like that help us fine tune the algo and those happen fewer and fewer.
