Show HN: Carrie, for what Calendly can't do https://ift.tt/jz98xi4

Show HN: Carrie, for what Calendly can't do Hey everyone, Through my career, I've spent too many hours and too much mental load on busywork like scheduling and following up on people's availabilities. So, I built Carrie. You simply cc her into your emails, and she sorts out meeting times across time zones, finds what works best for everyone, confirms the meeting and sends the invite. She handles scenarios beyond what Calendly can handle and it’s been freeing me up from the back-and-forth of juggling different meeting requests. I’ve been testing this with a beta group of users and am now looking to expand the user pool (please feel free to join the waitlist if you're interested). Would also love feedback on whether this seems useful and what seems to be missing to make this part of your workflow. Thanks! https://getcarrie.com/ November 2, 2025 at 08:10PM

Show HN: I built a smart blocker after destroying my dopamine baseline https://ift.tt/ceHO8by

Show HN: I built a smart blocker after destroying my dopamine baseline I'm a solo dev. A few years ago, I got addicted to Reddit. Spent months in that loop. Being a programmer, I thought I'd be clever. Redirected Reddit's domain to nowhere in my DNS file. Worked great until I'd just... open the file and undo it 20 minutes later. So I made it irreversible. Locked the DNS file so it can't be edited unless I boot my Mac in safe mode. And if I do that, there's a script that instantly locks it again. Haven't used Reddit since last year. Problem solved, right? Wrong. I just replaced Reddit with Twitch and YouTube. Started keeping streams running in the background while I coded. This went on for almost a year. It killed my ability to focus. If you know about dopamine, you know your brain releases it when it wants you to repeat an activity. The constant background streams destroyed my dopamine baseline. When I tried to code without anything running one day, it felt genuinely weird. Hard problems that used to be interesting just felt like grinding. I tried blocking Twitch and YouTube the same way I blocked Reddit. But I actually need YouTube for learning. I watch programmers on Twitch I learn from. I couldn't just nuke them entirely. So I built something smarter. The first version was terrible. Blocked things it shouldn't, let through things it should've blocked. Really buggy and annoying. Then I added AI. I tell it what I'm working on, and it blocks anything unrelated to that task. This was the breakthrough. I need YouTube for tutorials, but I don't need 3-hour video essay rabbit holes. The extension knows the difference now. It reminds me in the moment. Not after I've already wasted an hour. Right when I'm about to click into the distraction, it stops me and makes me think: "Is this what I'm supposed to be doing right now?" The result: I actually enjoy hard problems again. Turns out I wasn't burned out, I'd just wrecked my brain's reward system. Then I had to market this thing, so I started using Twitter. And oh boy, Twitter is addicting. You post something and wait for the notification to light up. I had to install my own extension on my Twitter Chrome profile. It's wild how effective it is when something reminds you "you're here to market, not scroll" right as you're about to fall into the feed. It's still hard sometimes. Your brain will try to disable it. But having something that catches you in the moment before you lose an hour makes all the difference. It's a Chrome extension, currently at beta v1.0.43: https://ift.tt/sZYW90z... It's free, no signup, no payment. Just install it. Fair warning: it's still in beta. There will be bugs. But it works well enough that I use it daily, and it's helped me get my focus back. Built this to fix my own problem. Figured other devs might be in the same boat. Question for HN: Anyone else dealt with this? The programming with streams thing destroyed my focus for almost a year before I realized what was happening. What worked for you? https://ift.tt/TcfNXke November 2, 2025 at 11:17PM

Show HN: Micro-RLE ≤264-byte compression for UART/MCU logs, zero RAM growth https://ift.tt/Pg74n2l

Show HN: Micro-RLE ≤264-byte compression for UART/MCU logs, zero RAM growth I needed to stuff twice the telemetry through the same 115 kbaud line on a Cortex-M0+ that only had 8 kB flash left. Micro-RLE is the smallest drop-in I could come up with: 264 B of Thumb code, 36 B of state, no malloc, worst-case 14 cycles/byte and still lossless for every 8-bit pattern. On the usual sensor streams (ADC, IMU, GPS) it’s 33-70 % smaller than raw output and boots in < 600 µs, so you can fire-and-forget from main() before the PLL even locks. Repo is a single .c file and a 3-function API—replace the weak emit() hook with your UART / DMA / ring-buffer and you’re done. Size proof: arm-none-eabi-size micro_rle.o text data bss 264 0 36 MIT licensed, link in the repo. Happy to hear where else this fits! https://github.com/CoreLathe/Micro-RLE November 2, 2025 at 12:34AM

Show HN: Why write code if the LLM can just do the thing? (web app experiment) https://ift.tt/MlCP0FG

Show HN: Why write code if the LLM can just do the thing? (web app experiment) I spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI consistency between requests. The capability exists; performance is the problem. When inference gets 10x faster, maybe the question shifts from "how do we generate better code?" to "why generate code at all?" https://ift.tt/2vwcg1s November 1, 2025 at 11:15PM

Show HN: First5Minutes, Your first 5 minutes decide your day https://ift.tt/6x5A9Ln

Show HN: First5Minutes, Your first 5 minutes decide your day Hi everyone I have been experimenting with a simple idea. What if the first five minutes of your day decided the rest? I built First5Minutes, a small web app that helps you start strong. You choose one meaningful mission for the day and complete it with quick photo, video or text proof. I created it to fix my own habit of overplanning and not starting. The focus is on doing one real thing each day, not maintaining long to do lists. Key features: • One mission per day for focus • Quick proof capture with photo, video or text • Optional partner verification for accountability • Streaks based on proof, not checkmarks Try it here → https://ift.tt/yauEJWg No install or sign up wall. Just start a mission. I would love your feedback on: • Is this level of simplicity helpful or limiting • What part made or failed to make you feel you actually did something • Any friction in completing your first mission Built with Next.js, Supabase and Clerk. Thanks for checking it out. I appreciate your time and thoughts. https://ift.tt/3jOeN4C November 1, 2025 at 01:42AM
