01
SSE for rare alerts: when WebSockets are the wrong interrupt
Sep 23, 2026
Site-wide ‘special report is live’ toasts are one-way and infrequent. Why Server-Sent Events (or even short polling) beat idle WebSocket farms for that product shape, using Northlight Press as the example.
02
Same-bucket HLS: MediaConvert without a second CloudFront
Sep 21, 2026
When video transcoding wants a dedicated HLS bucket and CDN, but your API already exposes one public media domain. Why Northlight kept uploads and playlists on the same S3 + CloudFront, and what has to stay in-region for job events.
03
S3 Transfer Acceleration: when enabling the bucket flag is not enough
Sep 19, 2026
Turning on S3 Transfer Acceleration in the console does nothing for your app until signed upload URLs hit s3-accelerate. How it speeds long-haul uploads, when it will not, and the one-line SDK change that actually matters.
