How to sideload Android APKs on your Chromebook

A Chromebook can be used for productivity, gaming, and entertainment, and users can sideload Android apps when they are not available on the Google Play Store. Sideloading involves installing Android Package Kits (APKs) directly onto the device, but caution is advised as these apps have not been verified by Google. Users should research APKs to ensure they are legitimate and free from malware. To sideload an app, users can enable Linux on their Chromebook and use Android Debug Bridge (ADB). This requires enabling ADB debugging in the Linux development environment and using the Terminal to install the APK. Alternatively, users can run APKs using an emulator in Android Studio, which involves setting up Android Studio and creating an Android Virtual Device to install the APK.

How to Retrieve Deleted Facebook Messenger Messages?

Deleted Facebook Messenger messages are removed from the user's view but may still exist in local storage temporarily, while Meta retains server data for specific periods based on the deletion type. 1. Unsend / Remove for Everyone: Messages are removed from all chats for up to 14 days (or 6 hours for end-to-end encrypted chats). 2. Deleted Facebook Account: Messages are removed from active servers but may remain in backup storage for 90–180 days. 3. Deleted from Your Inbox Only: Messages are removed only from the user's view; the recipient retains their copy. To recover deleted messages, users can rely on backups through Google Drive or local copies, and Facebook's "Download Your Information" feature, which may not include unsent messages. Dr.Fone – Data Recover (Android) is a recovery software that can scan phone storage for remnants of deleted messages, supporting over 14 data types across more than 6000 Android devices without needing root access or USB debugging. Steps to recover messages using Dr.Fone: 1. Access the Data Recovery tool for Android and select “Recover Android Data.” 2. Initiate a read-only scan for messages. 3. Filter and preview messages, then restore them to a chosen export location. To prevent future loss of important messages, users can: - Enable Google Drive Backup. - Archive conversations instead of deleting them. - Download a Facebook Data Archive. - Screenshot critical messages. - Enable end-to-end encrypted chats. - Use Dr.Fone for regular backups.

Minecraft Java Edition Now Demands 16GB RAM in First Hardware Overhaul in 17 Years

Mojang Studios has updated the system requirements for Minecraft: Java Edition for the first time in 17 years, raising the recommended memory to 16GB of RAM. The new minimum specifications include a 64-bit operating system, a quad-core CPU, a graphics card supporting Vulkan 1.3 API with at least 2GB of VRAM, and 8GB of system RAM for discrete GPUs or 12GB for integrated graphics. For the recommended "Fancy" preset, 16GB of system memory, a current-generation processor, and a graphics card with 6GB or more of VRAM are required. Older hardware may struggle to run the game, leading to low frame rates and visual issues. Mojang is transitioning from OpenGL to Vulkan to enhance game performance and visuals. Players can still use Minecraft: Bedrock Edition for lower system requirements or community optimization mods like Sodium to improve performance on less capable hardware.

CrashStealer Mac malware steals passwords and wallets

A sophisticated new malware targeting Mac users, named CrashStealer, has been discovered by security researchers at Jamf Threat Labs. It masquerades as Apple's legitimate crash-reporting software and was first identified in May 2026, with active attacks detected by early July. CrashStealer is designed to extract sensitive information, including browser credentials, password manager data, and cryptocurrency wallet information, and can copy the Mac login Keychain. It uses native C++ programming, encrypts collected files, and employs anti-debugging features. The malware is distributed through a disk image labeled "Werkbit Setup," which features a polished installer that bypasses Mac security warnings by using a valid Apple Developer ID and notarization ticket. Once opened, it connects to GitHub for commands and downloads a script that installs a second disk image named CrashReporter.dmg, which mimics an Apple system component. CrashStealer presents a fake password prompt resembling a legitimate macOS request, verifying entered passwords locally. It targets data linked to various browsers and password managers, scanning for approximately 80 cryptocurrency wallet extensions and 14 password managers. Stolen data is stored in hidden folders, encrypted using AES-256-GCM, and packaged into hidden ZIP archives before being uploaded. Warning signs of infection include a website requiring a meeting PIN for download, unexpected password prompts, and unfamiliar apps requesting Full Disk Access. Users are advised to download apps from verified sources, avoid overriding security warnings, pause before entering passwords, review app permissions, install security updates, use antivirus software, and act quickly if they installed Werkbit Setup.

Simplify AI agent orchestration with Lakebase Postgres

The auditing process has traditionally been labor-intensive, requiring extensive document reviews. CLA (CliftonLarsonAllen LLP) partnered with the Databricks Forward Deployed Engineering team to develop a document processing application that reduces extraction time from hours to minutes while maintaining quality. The application is built on the Databricks platform, utilizing technologies like Lakebase Postgres, Databricks Apps, Lakeflow Jobs, MLflow, and Unity Catalog Volumes. The application addresses challenges in document parsing, including unpredictable per-task latency, rate-limit-aware throttling, workload prioritization, cost attribution per task, and real-time progress visibility. It eliminates the need for multiple specialized systems by integrating components such as a web application for user interaction, Lakebase for state management, an orchestrator for task management, and AI agents for document processing. The task queue is supported by two Postgres tables in Lakebase, tracking task status and execution attempts. Concurrency safety is ensured through a locking mechanism, and crash recovery is facilitated by lease-based locking. The orchestrator implements rate-limit-aware throttling and idempotent webhook callbacks to manage task processing effectively. An operator dashboard provides real-time metrics on task status, agent performance, and workload costs, with live updates through Postgres LISTEN/NOTIFY events. Cost attribution is managed at the application level, allowing for detailed monitoring of expenditures. Lakebase enhances the orchestration process with features like autoscaling compute, OAuth-rotated authentication, Unity Catalog integration, and support for branching and snapshots.

I Built My Second ETL Pipeline. This Time, I Started Thinking Like a Data Engineer

The author transitioned from a data analyst role to a data engineer, creating a 12-month self-study roadmap focused on learning by building projects. The first project was a GitHub ETL pipeline, which evolved from a simple Python script to a more complex system using SQLite and GitHub Actions for automation. The author realized that the challenges of data engineering lay in system design and orchestration rather than just writing ETL logic. For the second project, the author built an automated RSS ingestion pipeline to explore engineering decisions in creating a reliable data pipeline. The project emphasized the importance of separating application responsibilities from orchestration tasks, leading to the use of Docker for consistent execution environments and Kestra for orchestration. The author validated each component of the project incrementally: first the Python ETL, then PostgreSQL, followed by Docker, and finally Kestra. This approach ensured that each layer functioned correctly before adding complexity. The final architecture included distinct responsibilities for each component: Python for data processing, PostgreSQL for data storage, Docker for execution, and Kestra for orchestration. The author learned that effective engineering involves considering system reliability, error handling, and observability, shifting the focus from merely writing code to designing entire systems. The experience transformed the author's mindset, emphasizing the importance of incremental building and the separation of execution and orchestration responsibilities.

I found a hidden way to limit RAM on Windows 11, and the results were way more surprising than I expected

Windows 11 allows users to limit RAM usage through the System Configuration tool (msconfig) for testing and troubleshooting purposes. Users can specify the maximum memory in megabytes, but there is no simple option to set a fixed amount like "4GB of RAM." Limiting RAM can degrade performance and may cause applications to become sluggish. To limit RAM, users must navigate to the Boot tab in msconfig, check the Maximum memory option, and enter the desired amount. To restore full RAM access, users need to uncheck the Maximum memory option in the same tool. On some modern systems with UEFI firmware and Secure Boot enabled, the Maximum memory setting may not be accessible, and disabling Secure Boot may be necessary to apply the limit. Disabling Secure Boot can reduce security against boot-level malware.

MSYS2 And The No-Fuss Way To Get More GNU Into Your Windows

The Windows desktop experience has a streamlined interface, but its command line interface (CLI) offerings, particularly the cmd.exe shell, have been criticized for lacking the features found in UNIX/BSD/Linux environments. Microsoft’s transition to PowerShell has disappointed users who prefer a more traditional CLI experience. Despite Windows NT operating systems being POSIX compliant, they have historically lacked a suitable shell. MSYS2 provides a solution by offering a Linux-like experience with a Bash shell and the pacman package manager, allowing users to run shell scripts and access various tools. However, binaries compiled in MSYS2 may depend on shared libraries not included in the Windows system path. Upon installation, users can choose from different terminal options, with the UCRT terminal recommended for its usability. MSYS2 facilitates a streamlined development workflow, enabling the use of familiar tools across multiple platforms, but it does not achieve perfect integration within Windows and has some limitations, such as issues with stdout output in Bash.
