The repository provides a version of OrcaSlicer that re-enables full BambuNetwork connectivity for Bambu Lab printers, allowing remote operation over the internet rather than LAN‑only. Windows users must install WSL 2: run the commands `dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart` and `dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart`, then restart before launching Orca Studio. Linux installations require only the standard setup. Development is ongoing, and the author recommends using the BMCU firmware, which is available in their other repositories. The page includes an OrcaSlicer logo image.

Googlebook “Designed for Gemini Intelligence,” slated for release in Fall 2026, showcases the Gemini AI platform and its “Magic Pointer” interaction model, which enables users to select any on‑screen element and immediately query, compare, or generate content with Gemini. The promotional material includes visual examples: a band‑poster composition prompt, a live‑trip‑tracker widget for an Iceland itinerary, a desktop search interface suggesting mobile apps, and file‑access integration across phone and desktop. Additional imagery lists major PC manufacturers (Acer, Asus, Dell, HP, Lenovo) and highlights keyboard key designs featuring a fingerprint imprint and the Google “G” logo. The content emphasizes Gemini’s capability to blend visual selection with AI‑driven creation and information retrieval across devices.

Needle is a 26‑million‑parameter “Simple Attention Network” distilled from Gemini 3.1, designed for tiny consumer devices. The architecture uses a 512‑dimensional hidden size, 8 attention heads with 4 key/value heads, a BPE‑8192 tokenizer, and replaces feed‑forward layers with gated residual blocks and ZCRMSNorm. It employs masked self‑attention with RoPE, GQA, and cross‑attention from a 12‑layer encoder to an 8‑layer decoder; embeddings are shared between encoder and decoder. Pre‑training ran on 16 TPU v6e for 200 billion tokens (≈27 h), followed by 2 billion tokens of single‑shot function‑call data (≈45 min). Inference achieves ≈6000 tokens/s prefill and 1200 tokens/s decode, surpassing FunctionGemma‑270 M, Qwen‑0.6 B, Granite‑350 M, and LFM‑2.5‑350 M on single‑shot function‑call tasks, though larger models perform better in multi‑turn dialogue. The repository provides open weights, a CLI, and a web UI for testing and fine‑tuning (e.g., `needle finetune data.jsonl`). Citations list the development team and GitHub URL.

A blog post dated May 12 2026 describes a DIY graduation‑cap project that lights up when the tassel is moved. The author built the system using a Digispark ATtiny85 microcontroller, 48 WS2812B addressable LEDs, a reed switch with magnet for tassel detection, a USB‑C Power Delivery trigger board, and a power bank. The firmware was written in Rust, requiring forks and patches to the avr‑hal and ws2812‑avr crates to support the ATtiny85 at 16 MHz; this coding phase took roughly two hours, while hardware assembly took three-plus hours. The author notes that using Arduino libraries or a different board would have been simpler, but chose Rust for thematic consistency. The cap is not intended for actual graduation use, as it appears tacky. Source code is available on GitHub (ericswpark/gradcap-rs). Additional anecdotal notes include the cost of renting cap and gown ($94) and a warning about strobing video content.

Kraftwerk’s 1976 album *Radio‑Activity* marked a pivotal fusion of electronic music and sociopolitical commentary. The cover artwork, created by long‑time collaborator Emil Schult, paired a radioactive symbol with neon aesthetics. Live performances featured a light‑triggered “percussion cage” devised by Wolfgang Flür, which often malfunctioned onstage, illustrating the band’s experimental stagecraft. Musically, the title track evolved from an elegiac melody into a pronounced anti‑nuclear statement, influencing diverse genres and later being sampled by New Order, The Chemical Brothers and even mainstream pop acts such as Miley Cyrus. The album’s legacy lies in its synthesis of avant‑garde electronic production, visual design, and activist messaging, cementing Kraftwerk’s role in shaping synth‑pop, techno, and broader contemporary music culture.

The article outlines six typographic techniques that convey a “future” aesthetic: 1. **Italic slant** – suggests forward motion. 2. **Mixed curvature and angles** – combines smooth and sharp forms. 3. **Added “V” strokes** – extra diagonal elements on letters. 4. **Letter merging (kerning tricks)** – reduces spacing to create a compact look. 5. **Selective removal of elements** – e.g., deleting a horizontal stroke. 6. **Surface treatments** – noise texture, steel‑brushed metal, blue lighting, embossing, and star‑field backgrounds. These rules are illustrated with progressive examples applied to Eurostile Bold Extended text, advancing from a 2016 style to a 2092 “future” look. The piece cites numerous film logos that employ most or all of the rules, including *Blade Runner*, *Battlestar Galactica*, *Transformers*, *Guardians of the Galaxy*, *RoboCop*, *Star Wars*, *The Amazing Spider‑Man*, *Captain America: The Winter Soldier*, *Alien vs. Predator*, *G.I. Joe: Retaliation*, *WALL‑E*, *Back to the Future*, and *Star Trek: The Next Generation*. An expanded version appears in the “Typeset in the Future” book (pre‑order Dec 11 2018, Amazon).

CERT has disclosed six CVEs affecting dnsmasq, covering long‑standing bugs that impact virtually all non‑ancient versions. Pre‑disclosure to vendors was done, and patches are posted at https://thekelleys.org.uk/dnsmasq/CVE/. A “2.92rel2” release of dnsmasq 2.92 incorporates these patches; corresponding fixes are also being committed to the development tree, with some backported patches and several more extensive rewrites addressing root causes. The author notes that AI‑generated security research has produced a high volume of bug reports, making embargo coordination impractical and emphasizing prompt public fixes. An upcoming dnsmasq‑2.93rc1 will be tagged shortly, with testing encouraged to expedite a stable 2.93 release within weeks. Continued AI‑driven bug reporting is expected, so further rapid patch cycles are anticipated.

Senior developers often operate within two simultaneous feedback loops: one that drives market exploration and reduces uncertainty, and another that maintains existing services and manages complexity for stability. Their primary responsibility is to keep systems understandable, debuggable, and stable, so increasing complexity directly threatens the second loop’s goals. Communication breaks down because developers explain resistance to new work in terms of complexity and maintenance costs, while the rest of the organization prioritizes rapid uncertainty reduction. The article argues that developers should reframe proposals as solutions that speed up learning—e.g., “Can we try something quicker?”—emphasizing reuse of existing tools (Google Forms, UI tweaks, minimal analytics) rather than building from scratch. This aligns their expertise with business needs, allowing them to reduce unnecessary work while preserving stability. The piece also notes that AI, despite accelerating development, cannot replace the senior developer’s responsibility for overseeing system integrity and managing complexity.

CUBIC, the default congestion controller in Linux and Cloudflare’s QUIC implementation quiche, suffered a bug that left the congestion window (cwnd) permanently at its minimum (≈2700 bytes) after a loss‑induced collapse. * Test: a localhost HTTP/3 download (10 MiB, RTT 10 ms) with 30 % loss for the first 2 s. After loss stopped, 60 % of runs timed out because cwnd never grew. * Symptom: rapid oscillation (≈14 ms per transition) between recovery and congestion‑avoidance states while bytes‑in‑flight stayed at zero, locking cwnd at the floor. * Root cause: quiche’s `on_packet_sent()` treated any send when `bytes_in_flight == 0` as an idle period, shifting `congestion_recovery_start_time` forward by `now – last_sent_time`. When cwnd is minimal, this delta equals roughly one RTT, incorrectly extending the recovery period and preventing cwnd growth. The logic mirrors a 2017 Linux kernel fix that later added a safeguard against setting `epoch_start` in the future. * Fix: record the timestamp of the last ACK (`last_ack_time`) and compute the idle delta from the later of `last_ack_time` or `last_sent_time`. Updating `congestion_recovery_start_time` with this corrected delta stops the self‑perpetuating recovery loop, allowing cwnd to follow the normal CUBIC curve and restoring 100 % test success.

Chris Morgan blocks URLs containing query strings, assuming the Referrer header suffices to identify traffic sources. In practice, most visitors arrive via links in email or mobile apps (e.g., Instagram, iOS Messages, Substack) that do not send Referrer headers, causing them to be classified as “Direct/Unknown.” To compensate, the author appends a custom query parameter (e.g., utm_source=Robin_Sloan_sent_me) to every outbound link, allowing destination sites to trace the origin of clicks—especially useful for e‑commerce platforms like Shopify. The author does not use analytics but views the parameter as a digital‑etiquette practice, enabling site operators to verify and follow up on traffic (illustrated by a planetarium confirming legitimate subscriptions). Some services, notably YouTube, reject unexpected query strings; the author maintains an exception list, now including chrismorgan.info.
