I almost reported a critical bug that didn't exist. One constant saved me.
Last week I was reviewing the staking engine of a protocol before its mainnet launch. Deep in a 1,400-line contract, I found what looked like a serious bug. The reward math multiplied three values before dividing: uint256 delta = (lot.amount * rBase * midpointRate) / (RAY * RAY); Multiply-before-divide. If that intermediate product overflows uint256 , the whole epoch settlement reverts — and since every stake , withdraw , and setStake runs it, the post's funds get permanently frozen . That's a High-severity, fund-locking DoS. I had the finding half-written. lot.amount can reach 10M tokens ( 1e25 ). rBase grows with elapsed time. midpointRate can hit RAY . Multiply those and you blow past 2^256 ... I was ready to send it. Then I did the one thing that separates a real audit from false-positive spam: I checked the actual constants before writing the claim. uint256 private constant RAY = 1e18; // I'd assumed 1e27 RAY was 1e18 , not the 1e27 I'd been carrying in my head. And the interest rate had a hard cap — MAX_RATE_MAX_RAY = 5e18 , enforced even against a fully-captured timelock. I ran the numbers with the real values: For that multiplication to overflow, the protocol would need to go 2.3 × 10¹⁵ years without a single state update. Not reachable. The bug didn't exist. I deleted the finding. Why this matters more than the bug would have If I'd sent that report, here's what happens: the team's engineer clones the repo, plugs in the real constants, and realizes in ten minutes that I flagged an overflow that can't happen. Every other finding in my report now gets read with a raised eyebrow. My credibility — the entire product — is gone. This is the dirty secret of automated smart-contract auditing: the bottleneck isn't finding issues. It's not drowning the real ones in false positives. Anyone can run a scanner and paste 40 "criticals." A team that has to triage 40 flags to find the 2 that matter will — correctly — stop trusting you. The bar I hold: zero false positives o

How to Build a Launch Plan Template for Startups That Actually Gets Used
Originally published at boldpilot.club Most startup launches fail not because the product is wrong, but because the planning collapses under its own ambiguity. A solid launch plan template for startups gives you a structure that converts vague intentions — "we'll do some PR, post on social, maybe a Product Hunt thing" — into sequenced tasks with owners and deadlines. If you're building something and your launch plan currently lives as a notes app dump or a half-filled Notion page with seventeen unticked checkboxes, that's the problem this article addresses directly. A usable launch template has five core components: a pre-launch timeline, a channel priority stack, a messaging framework, a metrics baseline, and a post-launch review cadence. Everything else is optional decoration. Why Most Launch Plan Templates Get Abandoned The templates people download from Google — the ones with seventeen tabs and color-coded Gantt charts — get opened once and then quietly archived. I've seen this happen with teams that had more than enough time and resources. The issue is that those templates are designed to look thorough, not to be used under the actual pressure of a launch week. According to CB Insights, 35% of startup failures cite "no market need" as the primary cause, but the second and third most common reasons — running out of cash and not having the right team — are both downstream of poor planning and sequencing. A launch plan that nobody opens doesn't prevent any of those outcomes. The templates that do get used share one quality: they're shallow enough to skim at 11pm the night before a deadline. One page if possible. Two at most. If your template requires a tutorial to operate, it's already failed. I'd push back on the common advice to "start with goals." Goals are fine, but most founders already know what they want — signups, revenue, waitlist growth. What they're missing is the sequencing. Start with the constraint instead: what's your actual launch date, and what ab

Presentation: From OTEL to SLMs: Distilling Frontier Model Behaviour from Production Telemetry
Ben O'Mahony discusses building custom AI-powered Language Server Protocols (LSPs) that go beyond standard rule-based checkers. He explains how to instrument AI agents natively with OpenTelemetry to track concrete user actions (accepting, dismissing, or regenerating code fixes) as implicit labels, creating a continuous data flywheel to distill frontier capabilities into cheaper, local SLMs. By Ben O'Mahony
