Blog Post Argues Signal's Usability Flaws Fuel Case for XMPP Adoption

A blogger recounts frustrations with Signal, including missing message-edit support until late 2023, unreliable notifications, broken Do Not Disturb call handling, and inconsistent emoji rendering, despite the app's praised encryption and open-source status. The piece uses these gripes to pivot into a broader discussion of why XMPP struggles for adoption compared to alternatives like Matrix, which offers a single documented client implementation versus XMPP's fragmented extension ecosystem.

HBO Max's verified Reddit account hijacked to spread ClickFix malware

Attackers took over HBO Max's official, verified Reddit account and used it to post 108 malicious ads over roughly two days, tricking Windows and macOS users into installing information-stealing malware. The ads used the ClickFix technique, luring victims into pasting attacker-supplied commands into Run, PowerShell, or Terminal under the guise of fixing errors or verifying CAPTCHAs, with some posts impersonating a fake HBO Max app and others posing as AI tools or developer utilities.

F1's new Madrid street circuit draws Monaco comparisons for length, not glamour

Formula 1 followed its Monza weekend—where Mercedes rookie Kimi Antonelli became the first Italian in 60 years to win the Italian Grand Prix—with a debut race on a new street circuit in Madrid. The Madrid layout is being likened to Monaco for its tight, twisty nature, but at roughly double the length and without the Mediterranean glitz that defines the Monaco Grand Prix.

Colossal Biosciences CEO to discuss AI-driven de-extinction at TechCrunch Disrupt 2026

TechCrunch Disrupt 2026, running October 13-15 in San Francisco, will host a fireside chat titled 'Can We Engineer Nature's Comeback?' featuring Ben Lamm, co-founder and CEO of Colossal Biosciences. The session will examine how AI and synthetic biology are being used to attempt reviving extinct species and what that means for conservation efforts.

Bomfather cuts eBPF security agent's kernel CPU usage by 90% via inode-level policy caching

The team behind the open-source Bomfather eBPF security agent found that the costliest part of their file-access enforcement wasn't applying allow/deny decisions, but repeatedly walking parent directories to determine which path-based policy applied to a given file. By caching the resolved policy per inode instead of recalculating it on every file open, they cut kernel-side CPU overhead by roughly 90%, particularly benefiting workloads like databases that repeatedly access the same file paths.

Developer Bridges ZLUDA and ROCm to Run CUDA Workloads on AMD GPUs in Windows

An independent developer known as Speedstu built a PowerShell-based toolkit that combines ZLUDA with AMD's HIP/ROCm SDK, allowing CUDA-only applications to run on AMD GPUs in Windows without dual-booting or virtual machines. The setup successfully mapped CUDA's driver API and libraries like cuBLAS, cuSPARSE, and cuFFT to AMD equivalents, and was tested by training a small reinforcement-learning model on a Radeon RX 9060 XT using unmodified CUDA code.

Category theorist extends Yoneda Lemma to double categories without presheaves

A category theory writeup describes how to construct a Yoneda-style embedding within double categories, a setting where presheaves cannot be directly expressed because objects are treated as abstract 0-cells rather than sets. The author sketches how to define a presheaf object and a Yoneda vertical arrow using universal constructions like horizontal arrows and left Kan extensions instead of direct references to sets or presheaves. A follow-up post is promised that will implement these ideas as working code in Haskell.

Former Spotify innovation chief raises $5.5M for music creation startup A Vinyl Bar in Shibuya

Máuhan M Zonoozy, who previously led innovation at Spotify and founded remix startup Bubbl before its acquisition by Cricket Media, has launched A Vinyl Bar in Shibuya, a startup building small apps for playing with sound and vocals. The company secured $5.5 million in pre-seed funding from investors including Mantis VC, SV Angel, Boxgroup, and former Spotify advertising executive Dawn Ostroff, who is advising the venture. Rather than one product, the startup releases experimental apps as 'singles,' such as a Chrome extension called Speed Surfer that alters browser audio and a stem-mixing tool called Stacks.

A Vinyl Bar in Shibuya raises $5.5M pre-seed for music interaction apps

A Vinyl Bar in Shibuya, a startup founded by former Spotify innovation head Máuhan M Zonoozy, has closed a $5.5 million pre-seed round from investors including Mantis VC, SV Angel, Boxgroup, and Dawn Ostroff. The company builds a series of small apps and web tools, like Speed Surfer and Stacks, that let users manipulate and remix sound and vocals rather than generate music via AI prompts.

2026 AI job data: AI Engineer tops hiring, wage premiums hit 62%

A roundup of LinkedIn, WEF, Stanford AI Index, PwC, Lightcast, Indeed, Bain and Levels.fyi data shows AI Engineer as the most-hired AI role in 2026, with Research Scientist at frontier labs seen as the most prestigious. AI-related job postings and wage premiums have surged sharply, while prompt engineering is fading as a title and entry-level hiring has become tougher.
