Meshtastic Gains Renewed Popularity as Offline LoRa Mesh Networks Expand for Remote and Disaster Communications

Meshtastic is experiencing a notable renaissance as interest grows in reliable communication networks that function without internet access. Originally developed in 2020, the LoRa-based protocol enables long-range mesh networking suitable for cities, disaster zones, hiking expeditions, and search-and-rescue missions.

Recent global internet disruptions have accelerated adoption, prompting users to seek resilient offline alternatives. New ready-to-use devices such as the Hacker Pager and Heltec V3 terminals, along with numerous DIY tutorials, have made the technology more accessible, including in regions of Russia where mobile coverage remains limited.

Two primary categories of Meshtastic devices exist. Stationary nodes installed on rooftops and elevated locations provide core network infrastructure, while mobile nodes function as portable radio modems that users carry or mount on vehicles. These mobile units connect to smartphones via Bluetooth and deliver an SMS-like messaging interface through official Meshtastic applications for Android and iOS.

The Hacker Pager stands out for its dual capability: it operates autonomously with its own interface yet also serves as a Bluetooth gateway for smartphones. This flexibility supports both independent use in remote areas and integration with mobile devices.

Practical projects illustrate the technology’s versatility. One enthusiast built a remote shed alarm by pairing an infrared beam sensor with a Heltec ESP32 LoRa module that publishes alerts over the mesh network. A second module connected to home Wi-Fi forwards these messages to Home Assistant using MQTT after switching to the RadioLib library for reliable signal handling.

Additional deployments include expeditions by the Mars Society, which employs T-Echo radios for astronaut training in areas without cellular or Wi-Fi service. Similar use cases encompass long-distance hiking, natural disaster response, and regions experiencing internet blackouts, with some municipalities evaluating Meshtastic as emergency backup infrastructure.

Although the DIY nature of early setups required selecting boards, 3D-printing enclosures, and configuring firmware, newer commercial products such as the T5 E-Paper S3 Pro priced at $84 now offer pre-assembled solutions with e-paper displays, reducing entry barriers for broader adoption.

Top LLMs Misidentify Poisonous Mushrooms in Every Ninth Case, Benchmark Shows

Polish developer Piotr Migdal evaluated leading large language models on their ability to identify mushrooms from photographs, using a dataset of 1040 images covering 55 species common in Poland. The images came from the FungiTastic dataset derived from the Atlas of Danish Fungi, with expert labels and partial DNA confirmation. Models were asked to return the five most likely species names in Latin without additional training or tools. Gemini 3.8 Flash performed best with 65 percent top-1 accuracy and 85 percent top-5 accuracy, followed closely by other Gemini variants. However, safety-critical errors remained high: Gemini models labeled poisonous mushrooms as edible in roughly 11 percent of cases, while GPT-5.6 Sol reached 24 percent, Claude Opus 5 reached 29 percent, and Qwen 3.8 27B reached 36 percent. The study did not ask models directly whether a mushroom was edible; species identifications were later cross-checked against toxicity tables.

September 2026 AI Model Rankings: Fable 5.1 Tops Intelligence Index as Competition Tightens Across GPT-5.6 Sol, Grok 4.6 and Muse Spark 1.3

The beginning of September 2026 marked a rare moment when the list of top language models had to be almost entirely rewritten. Anthropic released Fable 5.1 and the limited Mythos 5.1, while Meta updated Muse Spark to version 1.3, Google introduced Gemini 3.8 Flash, and Alibaba refreshed Qwen3.8-Max. Existing models including GPT-5.6 Sol, Grok 4.6, Kimi K3, GLM-5.3 and DeepSeek V4 Pro remain competitive. Traditional rankings from smartest to least capable have become difficult because modern models operate in multiple reasoning-depth modes where low, high and max settings can differ by ten or more points on the same test. The market is better viewed as several overlapping races where Fable 5.1 leads in complex reasoning quality, GPT-5.6 Sol and Grok 4.6 deliver near-top performance at lower cost, and Muse Spark 1.3 excels in price-performance. Independent Artificial Analysis Intelligence Index scores, context windows, API pricing and tool-use capabilities now determine practical choices more than raw benchmark numbers.

InfoWatch Acquires Web Control DC Team and Rebrands sPACE PAM as InfoWatch Privilege Control

InfoWatch has expanded its product portfolio by incorporating the Web Control DC development team and rebranding its flagship sPACE PAM solution. The new product, InfoWatch Privilege Control, is designed to manage and monitor privileged accounts belonging to system administrators, contractors, external specialists, and business users. These accounts provide access to servers, databases, network equipment, and critical applications, making them high-value targets for attackers. According to InfoWatch data, approximately 40% of critical information security incidents in Russia in 2025 were linked to the leakage or misuse of privileged credentials, while another 30% of confirmed cyberattacks occurred through compromised IT contractors. The solution enables time-limited privilege issuance, connection management, and detailed activity logging to prevent unauthorized actions. The original sPACE PAM product remains listed in the Russian software registry and holds FSTEC Russia certification at the fourth trust level, with compatibility for Astra Linux, Alt, and RED OS operating systems.
