POSTGRES POSTMASTER DOES NOT SCALE

Recall.ai, a company recording millions of meetings weekly, encountered perplexing 10-15 second connection delays to its Postgres database during peak loads. Investigations revealed the bottleneck was in Postgres's single-threaded "postmaster" process, which is responsible for spawning new connections and background workers. High rates of new connections and background worker churn during synchronized meeting “starts” saturated this core process, so the company implemented jitter in its EC2 connection bursts and removed parallel query spikes.

EVEREST RANSOMWARE CLAIMS 90GB DATA THEFT INVOLVING LEGACY POLYCOM SYSTEMS

The Everest ransomware group claimed to have exfiltrated 90GB of internal data from systems linked to Polycom, now owned by HP Inc., including engineering build environments, source code, and technical documentation for the RMX and RealPresence conferencing platforms. Evidence suggests the data originated in legacy Polycom environments from 2017–2019, predating HP's acquisition, though it remains unclear when the systems were accessed. HP Inc. has not confirmed the breach.

BITCOIN SLIPS BELOW $71,000 AS AI-DRIVEN TECH ROUT WORSENS

Bitcoin fell 7.5% in Asian trading on Thursday, slipping below $71,000 to lows near $70,700 as a global technology stock selloff spilled into crypto markets, driven by mounting concerns over peaking AI investment, stretched valuations, and disappointing earnings from firms including Alphabet, Qualcomm, and Arm. Analysts noted that the move below the low-$70,000s has accelerated a broader deleveraging, flushing out crowded positioning built during the post-ETF rally with heavy liquidations and price action now driven more by balance-sheet mechanics than narrative flow, marking the end of complacency rather than the end of institutional participation. The crypto selloff was compounded by brutal commodity moves, including silver plunging 17% and gold falling over 3%, triggering heavy liquidations in tokenized metals products on crypto venues and highlighting fragile conviction across risk assets rather than a clear trend reversal.

FIRST-EVER EXPERIMENTAL GENE THERAPY SEEKS TO RESTORE VISION BY REJUVENATING EYE NEURONS

ER-100 is an experimental gene therapy designed to restore vision by reviving damaged neurons in the eye. The approach resets aged retinal cells to a healthier state using epigenetic reprogramming. It received FDA approval for human trials last week. If successful, ER-100 could signal a broader shift in how age-related diseases are treated.
