I'll be Direct with the Question because there isn't much to talk about: How did you Validate your Saas Idea? Like, did you ask AI? Is it a good way to ask Ai? And what are the results? Or did you ask directly to your Target Costumers? And where?

I'm building a small SaaS project in India using vibe coding, and I'm currently stuck at the payment part. I basically need a simple setup where users can pay through UPI on my website (ideally a dynamic QR / UPI checkout), I get a webhook when the payment is successful, and then my backend can automatically activate the credits/subscription they purchased. Fast settlement would be a big plus, ideally same-day or close to instant. The problem is that I'm currently operating as an individual/...

Hi Folks, I made a Screen Recorder for tutorials/walkthroughs, that edits itself. The tagline is "Record messy, deliver professional". My special focus, is on people who struggle to talk while recording, making mistakes... repeating too much... It’s not about creating shiny demo videos, but about making real tutorials easier. There is plenty of other apps that does likely that (but not exactly), like Guidde, VideoMule, Tella, Descript, etc Most of them pretty sucessful. So the mar...

I've been a developer for over 10 years, most of which I've spent building mobile apps, web apps and larger systems for other companies. I recently decided it was time to build something of my own, and ended up building Sqanna , a platform for managing smart QR codes. I've had the idea for a really long time ever since we had issues with static QR codes at my old corporate job, so I figured I'd try to solve it. The basic idea is that you create a QR code once and can then change where it le...

I failed many times, now I’m building SaaS and I want it to be successful. But I have some sort of reflex or feeling that it won’t succeed. I’m trying to get rid of that thinking but it doesn’t seem to work. Is it happening to you? What do you think and do you have any advice? Pls help!

We recently released a feature called BugSmash drop (inspired by Cloudflare and Netlify drop) - where users can simply drop their html or zip and get a live hosted link in seconds. Idea was - users can have a quick and easy way to upload & host their claude/codex generated html previews and mockups - allowing them to quickly send a live link to their clients where they can review and share their feedback via BugSmash itself. But, what instead happened - Someone hosted a live gambling...

There's a split from neuroscience I can't stop thinking about as the real reason AI agents fail inside companies. Treat it as an analogy, not a literal claim, but it keeps holding. Your brain runs two memory systems (Complementary Learning Systems theory, McClelland et al. 1995). The neocortex learns slowly and holds general, world knowledge. The hippocampus learns fast: it captures specific episodes as they happen, then consolidates the ones that recur into durable, reusable procedure. A pr...

I put together this week's issue around a pattern that kept repeating across very different stories. Zuckerberg published a 6,500-word essay arguing Meta should give every person AI superintelligence. Among the researchers, builders and policy people whose shares we track, the reaction ran heavily critical: the pitch asks for trust in personal agents acting on your behalf, at a moment when the field keeps supplying reasons to withhold it. The same week: Anthropic's second company-wide risk r...

Most of the reasoning gains coming out of the big labs are still tied to scale. More params, more compute, better reasoning. That's been the play for a while. Ran into TwIL-LM2 which flips the script for narrow tasks. PEFT LoRA adapter on SmolLM2-1.7B, specialized purely for formal logic translation. On strict-7 scoring (no partial credit, exact-format required) it hits 0.2386 - ahead of Qwen3-8B at 0.2093 and Gemma-4-26B at 0.2050. On the loose-match six-lane average it's a different story (Q...

Headline says "bans humanoid robots, targeting China." Neither half of that is quite right. It's not a ban. It's an addition to the FCC's Covered List, which blocks new models from getting FCC equipment authorization. Anything you already own keeps working. The government's exempt too. And it doesn't name China. The FCC's own wording is "place of production, not by entity". A humanoid built in Vietnam gets caught by the same rule as one built in Shenzhen. China's obviou...

On Friday, Amazon customers received an email alerting them to an update to the site's terms and conditions. Most notably, it stated that disputes would now be resolved through arbitration and said users agree to a class action waiver. Amazon framed this as a "fast and efficient" way to resolve issues, but it notably would […]

Welcome back to TechCrunch Mobility — your central hub for news and insights on the future of transportation.

Dario Amodei is pushing back against the idea that he's been painting an overly pessimistic picture of AI.

Testing email workflows—like OTP verification, password resets, or automated notifications—is a core requirement for robust end-to-end (E2E) automation. However, automating Office 365 (O365) Shared Mailboxes via UI logins or legacy IMAP basic authentication is a nightmare. UI logins trigger MFA, IMAP basic auth is deprecated across Microsoft 365, and browser automation for Outlook web is notoriously flaky. The enterprise-grade solution? Use Microsoft Graph API with Client Credentials (Ap...

You will catch a GraphQL N+1 much earlier by counting how many times your batch loader is called against a temporary mock server than by measuring response time, because latency tests hide the problem behind small local datasets, in-memory caches, and a developer machine that is simply too fast to notice. The classic mistake is to add a deeply nested field, run one query that returns three posts, see a snappy response, and ship. That query may call the author loader three times instead of once, ...

This is a submission for Weekend Challenge: Dog Days Edition TL;DR — A walker records the walk on their phone, the route is hashed in the browser, and a 147-byte attestation signed by the walker's own key lands on Solana devnet. The owner checks the trace they were handed against the chain, and the app tells a tampered route apart from a corrupted file. Move one GPS fix eleven metres and the hash changes completely. That's the whole product. What I Built My ...

We've already seen that Raku understands characters like ∞ , and it would be logically that you can use them with ease, similar to any other constructs of the language. Take, for example, a sequence with no definite end. You define a pattern and take as many items as you need. say (1, 1, * + * ... ∞)[^10]; Here, the pattern defines a Fibonacci sequence and we only take the first 10 elements of it: (1 1 2 3 5 8 13 21 34 55) You don't know upfront what the 10 th element will be, s...

Introduction This week, I decided to slow down and go deeper into the Spring Framework . Instead of focusing heavily on building new features, I spent most of my time understanding what happens behind the scenes in the framework I use to build backend applications. I explored concepts around Spring AOP, JDBC, Caching, Reactive Programming, and Concurrency , learning not just how to use these features, but the problems they are designed to solve. Alongside my learning, I continued ...

It started with a Discord bot React ChatBotify is an open-source project I maintain, and part of that meant looking after its websites and servers. When things went wrong, the usual routine was to check services, inspect logs, and at times, the fix was as simple as a restart. Sometime in late July 2025, I started playing with a fairly simple idea - what if I could troubleshoot the infrastructure behind React ChatBotify simply by talking to a Discord bot? The idea wa...

TL;DR: If you have a Razer Leviathan connected via USB-C on Linux and the volume is incredibly quiet even at 100%, PipeWire is likely crushing your ALSA hardware baseline on boot. Just paste this script into your terminal to automatically fix it every time you log in: # 1. Create the necessary directories mkdir -p ~/.local/bin mkdir -p ~/.config/autostart # 2. Write the volume-fixing script cat << ' EOF ' > ~/.local/bin/fix-razer.sh #!/bin/bash # Wait for Pi...

GitHub’s page for Binaryify/open-kimi-ppt-skill says the repository was archived and made read-only after its contents were cleared for copyright reasons. That removal is the central fact about the project now: its listing still promises an unofficial Kimi Slides skill for AI agents, editable PPTD and PPTX output, and a local browser editor, but the repository provides no code with which to inspect those promises. The project’s visibility has outlasted its implementation. GitHub displays 1....

MVCC not only tracks row history but also records the search-key space. To better understand PostgreSQL MVCC, it's useful to look at some alternatives. One is zheap, which introduced out-of-place undo logging to rebuild historical row versions by storing old tuples in an undo log instead of the heap. This was done entirely at the table access method level, without modifying the index access method, but it was eventually abandoned. A more recent development is OrioleDB, which extends this approac...

I was staring at my Convex dashboard, confused. Convex is the reactive backend I use for a chat app: it stores the data and, the part that matters here, it keeps your queries live , so the UI updates the instant the data changes. The dashboard has a meter called "Database Bandwidth," and for two users, me on a dev account and me on a prod account, poking the app for maybe half an hour, it was reading tens of megabytes a day. That made no sense to me. It's a chat app. The actual messages we...

Ran into this last week on a multiline TextInput and lost a chunk of a day to it. Writing it up in case someone else hits the same thing. The bug I've got a multiline TextInput hooked up with react-native-controlled-mentions and a suggestions dropdown above it. You type a trigger character like @ to pick a suggestion from a dropdown, and the library inserts a styled name into the text box. Short insertions are fine but once the text is long enough that the inserted mentio...

So I have a bunch of small games on my site. Ludo, tic-tac-toe, carrom, rock-paper-scissors. Nothing fancy, the kind of thing you'd think runs on a potato. They're built with Three.js , which is the standard library for drawing 3D graphics in a web page. I was testing them on my iPhone and the phone got genuinely hot. Hot to hold. And here's the part that bugged me: I wasn't even doing anything. I was just sitting on the Ludo board waiting for my turn. Nothing on screen was moving. My first ...
