You could order my book directly from the publisher for the past couple of weeks, but I know that some of you don't want Jeff Bezos to starve. If so, I have excellent news: Amazon will start shipping tomorrow. Order now to impress your friends: amazon.com/dp/1718504802

Święto cyberprzestępców nadeszło. Wczoraj z funkcji Dyrektor Departamentu do Spraw Cyberprzestępczości i Informatyzacji Prokuratury Krajowej zwolniona została prokurator Agnieszka Gryszczyńska, jedna z najbardziej zasłużonych i zaangażowanych w zwalczanie cyberprzestępczości osób w Polsce, zawzięcie goniąca przez lata internetowych złodziei. Przestępcy świętują, w CBZC i branży cybersec żałoba. Dzisiaj prokurator Gryszczyńska złożyła rezygnację ze stanowiska prokuratora. Smutny koniec pewnej epoki.

Dostajesz załącznik PDF Signalem lub via Messages? Chwilowo spasuj z otwieraniem. Wykazano istnienie błędów, łatek jeszcze nie ma. Nie ma też konkretów i nie do końca wiadomo, na czym polega błąd. I czy np PDF odebrany przez Apple Mail też jest groźny. #iPhone vulnerability.

Today, we’re open-sourcing SPACE, the project I started after joining Perplexity. I’ve had the honor of leading it with a dedicated team of engineers, supported by brilliant colleagues and leaders. I chose to work on AI because I believe safety is an engineering problem. Careful design, ambitious architecture, and high-quality craft enable us to build safer products. SPACE is the first component of our agentic runtime platform. We’re sharing it so more teams can build safer products at scale. I’m proud of what we’ve built together and grateful to everyone involved. Excited for what’s next for SPACE and Perplexity Platform. perplexity.ai/hub/blog/open-…
