I had an idea to screen the YouTube videos that kids watch through a suitable LLM to assess whether the content was child friendly. There’s an emerging issue with insidious messaging / themes creeping into child-focused content that looks completely innocent on the surface, and I wondered if the current generation of LLMs can pick up on this. (Initial tests seem encouraging.)

#632Nothing.
Quite frankly, it feels great!

#633I've been building mentions.us[1] - it sends you alerts when your keywords are mentioned on Hacker News, Reddit, Bluesky, LinkedIn and a few other places. For anyone who uses F5Bot, it's similar but with some extra data sources and a Slack integration. It's been a fun project. Dealing with the scale of Reddit (~300 posts/second) creates some interesting technical challenges. It's also let me polish up my frontend dev…
Sounds very cool. I'm curious how you manage to monitor Linkedin though. The only tool that seems capable of monitoring Linkedin is https://kwatch.io , so if you manage to achieve that too it's impressive.
Hey Julien! I’ve seen you advertising KWatch in lots of places, assume you’re connected to it / know the founder?
For LinkedIn monitoring we use the voyager APIs. It’s not perfect because it gets posts but not comments, but it’s pretty good.

#634I’ve been developing an observability platform [0] for small teams and indie developers where they can track logs, live metrics, and get alerted in realtime through webhooks. I intend to develop a dead simple on-call calendar as well in the coming weeks.
After using tools like Sentry on apps serving millions of users, I always felt I was missing a cheap and dead simple approach to following what happened in my apps and apis, and basically became my first customer for all of my side projects and even got some friends using it for their SaaS and apps.

#635Busy building some personal infrastructure around information. Think mix of scrapping and filtering, scoring and summarization.
Clearly all of the info space is getting ever more polluted and I just don’t trust anyone else (with their own agenda) to manage and filter that for me. If one is to abdicate that sort of responsibility to a system wholesale then I think it has to be fully under one’s control, own data, own design, self hosted etc

Looks very interesting!! I registered and found an issue: when I add the mention keyword, it shows two results, but after saving it, it shows zero results. I tried checking mentions for my side project DollarDeploy.
Thanks for the feedback! For saved terms we show you the number of matches we’ve notified you about, which always starts at zero, whereas during creating we show you how many you would have matched. That’s a confusing UI and I should improve it

For the social platforms, are you hooking up to their APIs or just using Google? I'm only interested in emails and would pay a small price for that (say 5-7/month). I've signed up and added my first keyword to test. That being said, here is an additional feature: being able to track discord/slack/telegram by providing my API key and you streaming the content of the groups I've signed up to.
We’re hooking up to the APIs - the goal is to alert you of mentions as quickly as possible, so waiting for Google to index results would introduce (much) too much lag.
Interesting feature request! I’ll have a think on it.

#639I’ve been building https://lowlow.bot , it tracks price changes on any website. I was inspired by https://camelcamelcamel.com , but wanted something that worked for more than just Amazon. It’s been handy for big purchases I’m ok waiting for and stocking up on recurring non-perishable essentials when they go on sale. It also lets me know when something has come back in stock.
I’ll use it!
Please share feedback if you have any!

#640Working on adding features to my app.
I wrote BVCalc because I wanted a calculator that would show not only the numerical result value but also show the corresponding algebraic expression that I entered so that I could check for entry mistakes and more easily keep track of calculations. I also wanted this feature to work even when the calculator is in RPN mode. That is, I wanted to be able to use RPN entry, and have the calculator show both the result value and the corresponding algebraic expression (displayed using infix notation, not RPN) for each item on the stack.
I was surprised that such a feature was not available on any existing calculators and so I wrote my own. Runs on macOS, iPhone, and iPad.
