Postgres to Iceberg in 13 minutes: How Supermetal compares to Flink, Kafka Connect, and Spark

Supermetal introduced Iceberg sink support, allowing for data transfer from Postgres to Iceberg. In a performance comparison, Supermetal completed snapshotting in 13 minutes, while Flink took 90 to 116 minutes, Kafka Connect required 120 minutes, and Spark exceeded 3 hours. The tests focused on throughput during the snapshotting phase rather than latency. The setup used the TPC-H dataset with a scale factor of 50 and involved AWS infrastructure. Supermetal operates independently of Kafka, enabling direct data delivery from source to sink. It utilizes a JSON configuration file for deployment, supporting various catalogs and advanced configuration options. Supermetal's Iceberg writer can adjust settings based on the CDC source phase. Throughout the tests, Supermetal maintained low CPU and memory usage, while other tools faced challenges with performance and resource management. Data synchronization was validated across all tools, with Supermetal achieving at least 7x faster snapshotting performance without tuning.

36 Malicious npm Packages Exploited Redis, PostgreSQL to Deploy Persistent Implants

Cybersecurity researchers have discovered 36 malicious packages in the npm registry that impersonate Strapi CMS plugins. These packages exploit Redis and PostgreSQL, deploy reverse shells, harvest credentials, and establish persistent implants. Each package consists of three files—package.json, index.js, and postinstall.js—without descriptions or repositories, and all use version 3.6.8 to mimic legitimate Strapi plugins. The malicious packages follow a naming convention starting with "strapi-plugin-" and were uploaded by four accounts within 13 hours. The identified packages include names like strapi-plugin-cron, strapi-plugin-database, and strapi-plugin-server. The malicious code is embedded in the postinstall script, executing automatically upon installation with the same privileges as the user. The payloads evolve from exploiting Redis for remote code execution to attempting direct PostgreSQL database exploitation and deploying persistent implants for remote access. The campaign appears to target cryptocurrency platforms, as indicated by the focus on credential theft and digital assets. Users of these packages are advised to assume compromise and rotate credentials. This incident reflects a broader trend of supply chain attacks in the open-source ecosystem, with recent examples including credential exfiltration payloads in GitHub repositories and compromised GitHub Actions workflows. Group-IB reported that software supply chain attacks are increasingly reshaping the cyber threat landscape, targeting trusted vendors and open-source software to gain access to downstream organizations.

5 Windows 11 Features That Are Slowing Down Your Computer

OneDrive automatically backs up essential folders and personalized settings for Windows users, allowing seamless data synchronization upon signing into a Microsoft account. However, uploading data can strain computer resources, particularly RAM and CPU, and consume significant bandwidth. Users can pause syncing by clicking the OneDrive icon, selecting the gear icon, choosing "Pause syncing," and selecting a duration of 2, 8, or 24 hours. Windows 11 features modern transparency effects and smooth animations that enhance user experience but can impact system performance, especially on older hardware with less than 8 GB of RAM. Users can disable these effects by navigating to Settings > Accessibility > Visual Effects and toggling off Transparency effects and Animation effects. The startup apps feature allows essential applications to load automatically at boot, but too many startup apps can prolong boot time and strain resources. Users can manage startup apps by right-clicking the Start button, selecting Task Manager, navigating to the Startup app tab, and disabling unnecessary apps. Windows allows certain applications to run in the background for tasks like notifications and updates, but excessive background apps can hinder performance. Users can prevent specific apps from running in the background by going to Settings > Apps > Installed Apps, clicking the three-dot icon next to the app, selecting Advanced options, and setting Background app permissions to "Never." Windows Update can cause temporary slowdowns, and while blocking updates is not advisable, users can pause updates for one to five weeks by going to Settings > Windows Update and selecting the desired pause duration.

От ffmpeg до торрентов для терминала: 7 новых TUI-инструментов, которые советуем

Many developers are turning to TUI (Text User Interface) tools for tasks traditionally done in GUI applications. MONICA is an interactive layer over ffmpeg that simplifies command usage, available on GitHub. The lic tool allows users to create a LICENSE file with a single terminal command by selecting a license from a TUI menu. It can be installed via Homebrew or pip and debuted in late December 2024, receiving 21 stars. PNANA is a TUI editor that combines the simplicity of nano with features from modern editors like Sublime, built with C++17 and FTXUI. Users need to compile it from source as no binary releases are available. CodeWeaver compiles a codebase into a single Markdown document, allowing for easy sharing and documentation. It can be installed via Go. Clox (version 1.3) introduces console clocks and calendars in the terminal, supporting various time zones and formats, and can be installed as a Python module. Torrra v2 is a TUI torrent client that allows users to search and download torrents directly from the console, enhancing UI speed and navigation. It can be installed via pipx or other package managers. A command for visualizing git history in the terminal is provided: `git log --graph --decorate --all --pretty=format:'%C(auto)%h%d %C(#888888)(%an; %ar)%Creset %s'`. An alias can be created for convenience. All tools aim to enhance productivity in the terminal and are actively evolving.

Contain your Windows apps inside Linux Windows

WinApps and WinBoat are two solutions for running Windows applications on Linux. WinApps, developed since 2020 by Ben Curtis, allows users to run a genuine copy of Windows in a virtual machine (VM) and export individual applications to the Linux desktop using Microsoft's Remote Desktop Protocol (RDP). It supports various methods, including Docker, Podman, and KVM virtualization, with KVM offering extensive customization but requiring a more complex setup. WinBoat, a newer application at version 0.9.0, simplifies the user experience by automating much of the setup process and requires only Docker and FreeRDP to be installed. WinBoat is designed for ease of use, making it accessible for users less comfortable with technical configurations. Both tools allow users to run Windows software that may not work well under WINE, but running a full Windows OS in a VM involves licensing, maintenance, and resource considerations.

Creating a Data Pipeline to Monitor Local Crime Trends

The dataset utilized consists of police log entries from the Cambridge Police Department (CPD), which includes the date and time of incidents, type of incident, location, and a detailed description. The project follows a structured ETL process that involves extracting data via the Socrata Open Data API, validating the data for integrity, transforming it for optimal storage, and loading it into a PostgreSQL database. The extraction is performed using a Python client for the API, and validation checks ensure the presence of expected columns and the integrity of the data. The transformation process includes removing duplicates and splitting the datetime column into separate components. The data is then loaded into PostgreSQL, where a table is created to store the incidents. The entire ETL process is automated using Prefect, allowing for daily execution. Finally, the data is visualized using Metabase, which connects to the PostgreSQL database to create dashboards that display crime trends over time.
