A bit of context: I'm having fun building my app. I'm trying to built something truly great for monitoring. I run a pool of workers on a couple of VPSes and probes about 10k endpoints on a tight loop down to every 15 seconds. The part that was quietly bleeding money, was that every probe result got written to our document db and all dashboards subscribed to those documents with real-time listeners (onSnapshot). In Firestore that's the obvious way to build a live dashboard and it actually works great until you draw out the actual data flow: workers write on every cycle every write fans out to a read to every browser that is running the dashboard so cost just scales with amount of cycles and open dashboards The database quietly became a message bus with billing on every message. I guess this is how you learn about proper architecture the hard way. 😄 A good Friday evening, with a glass of whisky, I decided to make something cool. I wanted a true live experience for the users, directly on the website. Basically something that looked directly into the VPS. So I flipped it. The WebSocket is the source of truth for live fields The DB gets demoted to config + state transition "Still up" heartbeats get batched, instead of writing "200 OK" everything cycle, we switch to a transition model and flush the no-change on a interval Results: ~95% fewer DB writes Live status reads went to zero Time from probe to pixel went from 1-3 seconds to <300ms (p90) It feels a bit like cheating. Making the product insanely more cool and useful, while also cutting costs, and not only cutting immediate costs. This thing scales like crazy. Basically the only real thing needed is a good amount of memory. Memory is not cheap nowadays, but it's definitely cheaper than continuous real-time DB reads and writes. Some tradeoffs worth mentioning. I kept the DB listeners as fallback if socket drops. The UI degrades instead of breaking. Websockets are real ops work. Is has become a bit harder to maintain an

Back in the 1980s a debate raged about whether it was okay to let children use calculators in elementary school. Critics warned that giving kids calculators would lead to the "destruction of student math skills." A similar debate is happening today across a range of areas, including coding, writing and even music. Will using AI lead a brain drain across these and many other areas? One of my favorite authors is Isaac Asimov. He's better known for his Foundation and Robot series of books where he contemplates whether an algorithm can successfully predict (and guide) humankind's development and the relationship between super artificial intelligence and humans. In some ways he predicted what we're experiencing today with AI: the rise of powerful, inscrutable artificial machines that are so complex humans can't understand or maintain them. In the short story, "The Last Question" he wrote: "Multivac was self-adjusting and self-correcting. It had to be, for nothing human could adjust and correct it quickly enough or even adequately enough." We're living an age that was once the stuff of science fiction. The question is: what comes next? submitted by /u/SpiritRealistic8174 [link] [留言]

Lectric, which says the U.S. market is ripe for competition and choice, has launched three new brands in the past six months.

I’ve spent the last seven months building a tool I wish I’d had in my previous roles. MimicScribe is a macOS menu bar app that fits the "AI notetaker" category. It has accurate on-device speaker identification (a first possibly?), real-time meeting talking points for discovery calls, and a fully keyboard- and voice-driven interface. I believe the accuracy of the speaker ID system is its biggest strength. I used fluid audio’s port of ( https://github.com/fluidInference/FluidAudio ) Pyannote's com

While the AI fundraising machine keeps breaking its own records, some founders are building in the other direction. Mirror founder Brynn Putnam just raised money for Board, a startup focused on bringing people together through in-person games and social experiences. Cyberdeck creators are going viral crafting whimsical DIY computers that literally encourage users to touch grass. Unlike the AI-free browser crowd, this doesn’t just feel like backlash, […]
