Ghostty 1.4 fixes unsafe terminal output and paste handling

Ghostty 1.4 fixes security flaws involving terminal output, pasted commands, crafted directory names and macOS links. Some require a click or paste; others can trigger just by displaying malicious output. The terminal also adds complete Kitty graphics animation support and compresses hidden scrollback. Security fixes make this update relevant even to users who do not need the new display features.

Apple distinguishes browser certificate blocks from command-line trust

Apple confirms that some macOS command-line tools can still accept compromised eMudhra certificates even though Safari and apps using Apple’s networking frameworks block them. Tools such as curl and git can use a separate certificate file that bypasses those blocks. Apple documents an administrator workaround and warns that macOS updates can replace the edited file until its planned software fix arrives.

Reserving GPU spares can increase schedulable rack capacity

SkyPilot explains why allocating every node in an NVL72 rack can reduce usable capacity when hardware fails. In a cited NVIDIA model at two percent node unavailability, sixteen-node slices with two spares provide 27% more usable capacity than eighteen-node slices. Rack-aware placement preserves the fast internal network, while spare nodes let recovery stay within the rack; the percentage is modeled capacity, not measured application throughput.

Java startup caches need deployment checks, not just a successful build

XPipe’s developer describes failures encountered when shipping Java applications with ahead-of-time startup caches. A cache can load while class-linking optimizations are disabled, and cached machine-code adapters can fail on CPUs unlike the training machine. His account separates training, cache assembly and application startup, showing why build success alone does not establish either portability or the intended startup optimization.

Qwenputer compiles a small CPU into model layers

Qwenputer adds a compiled RISC-V processor to Qwen3.5-4B, using the model’s recurrent attention state as addressable memory. Arithmetic executes through added weights and decoding steps rather than an external calculator service. Divyansh Agrawal reports passing processor tests and running C and MicroPython, but the experiment needs a custom driver and performs calculations far more slowly than an ordinary CPU.

Misleading code names can derail an AI-assisted investigation

A browser-fingerprinting investigation found alarming function names and instruction-like strings inside an obfuscated anti-bot script. Researcher veritas reports that some models refused to analyze it, while another helped reveal ordinary browser and graphics checks. The author suspects deliberate interference with AI-assisted analysis; the article does not establish that the script performs the harmful activities suggested by those names.

Gemini 4 Carbon starts with restricted cyber-defender access

Google announced Gemini 4 Carbon for long-running engineering and cybersecurity tasks, but initial access goes to selected cyber defenders and trusted partners rather than all developers. Google reports stronger vulnerability-finding and patching results; its cited external security benchmarks were evaluated without guardrails. The announced introductory API prices are $2 per million input tokens and $10 per million output tokens, with wider rollout still pending.

Go’s noalloc checker makes allocation assumptions explicit

The experimental noalloc tool checks Go functions marked as entry points and follows their calls to find heap allocations. It combines compiler escape information with analysis of dependencies and offers bounded containers for reusable memory. A passing check is conditional: exemptions and allowlists are trusted, and allocations on certain terminating error paths or first-use setup are allowed.

Restore verification must check more than database row counts

ReviveDB says it restores every Supabase database backup into isolated PostgreSQL and compares it with an inventory from the same snapshot, including constraints, grants and row-level security policies. Storage files and Edge Function bundles receive hash checks, not execution tests. The distinction matters: a readable database dump and matching row counts alone cannot show that permissions or an application’s recovery are correct.

Vercel separates crawler blocking from assistant retrieval

Vercel Firewall now lets site operators log or block AI crawlers separately from AI assistants. Crawlers collect pages for indexing or training; assistants fetch pages in response to a user action or query. The managed ruleset can therefore block one category while permitting the other, and Vercel maintains its bot definitions as new bots are added.
