Cellebrite to Report First-Quarter 2026 Financial Results on May 14, 2026 The Globe and Mail
Chinese AI lab DeepSeek's last model release was V3.2 (and V3.2 Speciale) last December . They just dropped the first of their hotly anticipated V4 series in the shape of two preview models, DeepSeek-…
Deepseeks stock suggestions as of April 24 2026 US-Listed Rockets (6 Picks) NuScale Power (SMR) Exchange: NYSE This isn’t a nuclear renaissance play—that’s the obvious part. The market still treats Nu…
Tool: Millisecond Converter LLM reports prompt durations in milliseconds and I got fed up of having to think about how to convert those to seconds and minutes. Tags: tools
This week's edition of my email newsletter (aka content from this blog delivered to your inbox) features 4 pelicans riding bicycles, 1 possum on an e-scooter, up to 5 raccoons with ham radios hiding i…
