The Problem There are millions of people holding crypto who want to spend it on real things — hire a developer, buy a script, sell design work. But where do they go? Telegram OTC chats → chaotic, no protection, scam-heavy Forum classifieds → threads get buried in hours P2P exchange sections → designed for fiat conversion, not commerce I decided to build a dedicated marketplace for this. What I Built CryptoBoard — a classifieds platform with Web3 wallet authentication. 🔗 https://crypto.my-board.org/ Tech decisions: Auth : Wallet-only (MetaMask, Trust Wallet, WalletConnect). No backend user database with emails and passwords to get hacked. Listings : Icon-based instead of user-uploaded images. Keeps the UI clean and avoids the "flea market" look. Messaging : Built-in chat between buyers and sellers. Escrow : This is the interesting part (see below). The Escrow Problem with Digital Goods Traditional escrow works like this: Buyer sends money to escrow Seller delivers product Buyer confirms → escrow releases money But with digital goods (source code, design files), step 3 is broken: The buyer can receive the files, say "this isn't what I wanted," request a refund, and keep a copy The seller has no recourse The escrow service has no way to verify the claim My Solution: Human-Powered Escrow Instead of just holding funds, the platform admin becomes an active verifier: Seller sends product + testing instructions to admin Admin installs/runs the product on their own machine Admin performs agreed-upon tests and records a screencast Buyer watches the screencast — verified by a neutral party, not the seller If satisfied, buyer sends crypto directly to seller Admin verifies the on-chain transaction Admin delivers files to buyer Admin deletes all copies (per agreement) Is it scalable? Probably not infinitely. But for high-value digital transactions ($100–$10,000+), having a human in the loop is actually a feature, not a bug. Design Philosophy I deliberately chose not to allow user

There are advantages and disadvantages to both connection types. Here's how they compare and when you might choose one over the other.

Instacart introduced Blueberry, an AI-assisted incident response system that helps on-call engineers investigate production issues faster. It combines AI agents, operational data, and historical incident knowledge to generate grounded root cause hypotheses in Slack. It uses parallel subagents, MCP integrations, and incident history to reduce investigation time while keeping engineers in control. By Leela Kumili

Cellars sweat. On a warm humid day the air you let in is warmer than the cold concrete, and the moment it touches a cold surface it gives up its water. That's condensation, and over enough summers it's how a basement grows mould in the corners you never look at. I wanted a number that warned me before that happened. The catch I already knew going in: a raw relative-humidity reading isn't that number. This is Part 08 of the series. The hub was already in the house running other things, and the install was genuinely the easy 20 minutes. The part worth writing about is what came after the sensor showed up: turning its two raw readings into a dew-point spread, and deciding when that spread means "act" versus "ignore the spike." Why the H100, and why 868 MHz is the whole point The hub is a TP-Link Tapo H100 , a little smart hub that acts as a radio bridge for TP-Link's battery sensors — the T100 motion, the T110 contact, and the one I care about here, the T310 temperature/humidity sensor. Here's the load-bearing detail, and the reason I reached for this hub instead of a WiFi sensor: the Tapo sensors don't talk WiFi. They talk to the H100 over 868 MHz sub-GHz radio . That matters in a cellar more than anywhere else. Sub-GHz is long-range and punches through concrete and floors in a way 2.4 GHz WiFi simply doesn't. There's no WiFi worth having down in my cellar, and no interest in running a repeater into a damp room just to read a sensor. The T310 sits down there on a battery, the H100 upstairs where the network is, and the radio link between does the work. One H100 supports up to 64 sensors — for a house, more headroom than I'll ever use. Getting the sensors into Home Assistant The native TP-Link integration doesn't expose the H100's child sensors — it's built for the plugs and bulbs. The one that works is the community Tapo Controller integration (petretiandrea's TP-Link Tapo ), installed through HACS , the same custom-integration store I've leaned on throughout this ser

Not everyone needs a keynote slot to make noise at TechCrunch Disrupt 2026. Sometimes the best way to meet investors, customers, and partners is by exhibiting directly on the Expo Hall floor at San Francisco’s Moscone West from October 13-15.
