Kubernetes 1.36's unusedSince Field Turns Orphaned-Volume Hunting Into a Query
Kubernetes 1.36 adds an unusedSince timestamp to every PVC's status, turning orphaned-volume hunting from a manual cross-reference script into a one-line query — and a self-hosted PaaS's precondition for automated reclaim jobs.
What a Modal AI-Agent Sandbox Really Costs: The Multiplier Stack Comparison Sites Keep Getting Wrong
Modal advertises $0.0000131 per CPU core-second, but AI-agent Sandboxes are forced non-preemptible and region-pinned, pushing the real bill to 3x-5.25x that rate — not the 3.75x figure recycled across pricing-comparison sites, which doesn't match Modal's current docs at all.
Netlify Made AI Agents a Line Item: The Math Behind a $20 Credit Pool One Agent Can Drain in a Day
Netlify's April 2026 update didn't just kill seats — it made AI-agent token spend its own billable meter. Here's the actual math: a background agent can burn a month's $20 credit pool in hours, and Netlify's own numbers reveal a hidden 20% markup on top.
Railway Killed Its Own Zero-Config Builder Over a 17x Image-Size Tax — Here's the Actual Bill
Railway shut down active development of Nixpacks after its own numbers showed a 17x image-size tax against a hand-written Dockerfile. Here's what that actually costs, what Railpack fixes, and what a self-hosted PaaS should default to instead.
PaaS First, Kubernetes Second: The $600K Number Byteiota Got Right (and Wrong)
Byteiota's case for defaulting to PaaS over Kubernetes rests on a real $600,000-a-year platform-team number — but that's the cost of hand-building Kubernetes' lifecycle automation, not the cost of Kubernetes itself, and Cluster API v1.12 just automated the biggest line item in it.
The Solo-Developer Breakeven Calculator: When Railway's $10-15/Month Actually Costs More Than Owning the Box
Railway's real $10-15/month solo-developer bill is legit — but price your own maintenance hours at even $25/hour and the breakeven point against owning a Hetzner box moves dramatically. A worked table shows exactly where the math flips.
Render's April 2026 Egress Cut From 100GB to 5GB on Hobby: Recalculating a Bandwidth-Heavy App's Bill Before the August 1 Deadline
Render cut included egress from 100GB to 5GB on Hobby and 1TB to 25GB on Pro, then started billing overage at $0.15/GB. Here's the real before/after math for a bandwidth-heavy app before the August 1 auto-migration.
Render Cut Free-Tier Bandwidth 20x in April 2026 — Here's What the Same App Costs on a $4.59 Hetzner Box
Render's April 2026 repricing cut Hobby bandwidth from 100GB to 5GB and killed per-seat fees. A line-by-line recompute of what that costs a hobby blog versus a media-heavy team, and what the same workload runs on a self-hosted Hetzner box.
Render Kills Per-Seat Pricing: The Exact Team Size Where Flat Fees Flip Against You
Render dropped per-seat workspace billing for a flat fee on April 23, 2026 — but Pro and Scale flip in opposite directions, and the Scale breakeven doesn't land until 18 seats. Here's the exact math, who pays more, and what never enters the bill on an owned fleet.
