6 awesome things you can do with a terminal emulator on Android

Terminal emulators allow users to interact with operating systems through text commands. Termux is an open-source terminal emulator for Android available on the F-Droid store. Users can test internet speed directly from Termux by installing Python and using the speedtest command. Weather information can be accessed using the curl command for a three-day forecast, and users can create shortcuts for convenience. Termux can display system information using colorful ASCII art with tools like fastfetch or macchina. It allows remote access to the phone via SSH after installing openssh. Users can run AI chatbots locally using the command-line tool Ollama. Termux can also facilitate the installation of Linux-based operating systems on Android devices using the proot-distro tool.
Migrate Amazon Aurora PostgreSQL across major versions with active Debezium CDC connectors using native logical replication

Migrate Amazon Aurora PostgreSQL across major versions with active Debezium CDC connectors using native logical replication

Organizations using Debezium Change Data Capture (CDC) connectors on Amazon Aurora PostgreSQL-Compatible Edition face challenges during major database version upgrades. In-place upgrades require downtime, while blue/green deployments disrupt CDC event pipelines. A method using PostgreSQL's native logical replication allows migration between a source cluster (current version) and a target cluster (new major version) without a full connector re-snapshot. This approach minimizes risks of data loss and allows existing Debezium connectors to operate on the source during synchronization. The cutover process involves disabling the replication subscription, synchronizing sequences, creating a new Debezium replication slot on the target, and redirecting the connector, resulting in a brief pause for Kafka consumers. Prerequisites for this method include enabling logical replication on the source cluster, ensuring the target cluster is provisioned in the same VPC, and confirming that tables participating in CDC have primary keys. The process involves configuring parameter groups, creating publications, and establishing subscriptions for logical replication. During cutover, application writes are halted, and replication lag must be monitored to ensure it reaches zero before proceeding. After the cutover, ongoing monitoring of replication health and Kafka consumer offsets is necessary. Common failure scenarios include Aurora writer failover, Debezium connector stalls, large messages exceeding Kafka limits, DDL changes during synchronization, and long-running transactions blocking lag drain. Each scenario has specific symptoms, detection methods, and resolutions. Post-migration, organizations should establish monitoring for replication lag growth and Kafka consumer offset divergence. Automation can streamline the migration process for organizations managing multiple clusters, utilizing AWS Cloud Development Kit (CDK) constructs for cluster provisioning, schema replication, and cutover orchestration. After verifying stable operation on the target cluster, the old Debezium connector and source cluster can be decommissioned. Limitations include the absence of failover slots on Aurora PostgreSQL 17 and the need to handle TOAST columns appropriately.

How to Fix Minecraft Lag and Stuttering on PC and Mac in 2026

Experiencing a freeze in Minecraft Java Edition can be frustrating due to the game's demands on computer performance, which can lead to lag spikes, stuttering, and low FPS. Performance issues can often be resolved without new hardware by optimizing settings on Windows and macOS. To address lag, identify the type of lag and adjust settings one at a time, starting with visuals and add-ons, then moving to memory, Java, drivers, and multiplayer servers. Quick fixes include closing background apps, restarting Minecraft, testing in a single-player world, disabling shaders, using default resources, and lowering render distance. Different types of lag include low FPS, stuttering from world loading, network or multiplayer server lag, and performance drops after enabling visual add-ons. To diagnose lag, symptoms should be matched with potential causes and fixes, such as adjusting video settings or checking server performance. Common issues include low FPS, stuttering while exploring, FPS drops when shaders are enabled, resource pack hitching, and problems with memory allocation or incompatible Java versions. Each issue has specific symptoms, causes, and recommended fixes, such as adjusting render distance, disabling shaders, or ensuring the correct Java version is used. Platform-specific fixes for macOS and Windows involve updating drivers, managing graphics settings, and ensuring proper memory allocation. Configuration mistakes can hinder performance improvements, and hardware limitations may also play a role in lag. For ongoing issues, gathering relevant logs and system details is essential for seeking help, and preventative tips include maintaining a clean test profile, gradually adding mods, and matching versions carefully.

The offline messaging apps challenging internet shutdowns

Governments are finding it harder to suppress protests through internet shutdowns due to the use of offline messaging applications. Bitchat, an app launched in 2025 by Jack Dorsey, allows devices to communicate via Bluetooth without internet access and gained popularity during recent student protests in New Delhi amid an internet blackout. The Indian government attempted to block access to Bitchat's source code on GitHub, marking a notable first instance of trying to geoblock an open-source repository. On July 26, Bitchat had 430,000 daily active users in India, with 74% of global downloads occurring in the country from July 20 to July 26. The app has been used in various protests globally, including those in Hong Kong, Myanmar, Nepal, Uganda, Madagascar, and Iran. On July 23, the Indian government ordered GitHub to disable access to three Bitchat repositories in India quickly. Jack Dorsey expressed concerns about the Indian government's stance on Bitchat, while digital rights advocates criticized the government's actions as unnecessary. The repositories remained accessible in India and were mirrored on decentralized platforms, complicating removal efforts. India's government has increasingly scrutinized communication platforms based on their design, imposing restrictions on apps like Telegram and WhatsApp.
