Windows 95 used a very basic “trick” to detect setup files

Microsoft developed Windows 95 with innovative detection mechanisms to prevent external installers from downgrading essential system components. The team used a heuristics-based approach to identify installer files by analyzing their names for keywords like "setup," "installer," or "inst," and also considered variations in other languages. If these keywords were not present, the system would check the file path for "setup." File checks were delayed until the next start to catch improperly modified files, as some setup programs would exit Windows to run batch files. Additionally, live file checks were conducted for multimedia driver installations via INF files, which was a special exception.

PostgreSQL Extensions Are an Architecture Decision, Not an Afterthought

A common issue in database migrations is the unplanned accumulation of extensions in PostgreSQL, leading to extension sprawl. Teams often install extensions without documenting the rationale, resulting in a complex web of dependencies that complicates future upgrades and removals. The installation process involves PostgreSQL accessing a control file that details the extension's version and dependencies, which can lead to multiple extensions being installed unintentionally. Upgrading and removing extensions are often neglected, causing risks such as the loss of dependent objects. Extensions typically default to the public schema, which can become cluttered; relocating them to dedicated schemas can improve organization. Trusted Language Extensions (TLE) allow non-privileged users to utilize procedural languages in managed databases without needing superuser access. Key extensions recommended for use include pg_stat_statements, pg_trgm, hstore, citext, and PostGIS, each serving specific use cases. Proper governance is essential for managing extensions, including documenting their purpose, ownership, and dependencies, to prevent operational surprises.

You can soon restore Windows 11 from scratch even if it can’t boot up

Microsoft is previewing a recovery tool called Cloud rebuild for Windows 11, allowing users to reinstall the operating system from scratch even if it is unresponsive. This feature provides a clean version of Windows, free from previous drivers and files, and automatically includes the latest updates. Unlike the existing "Reset this PC" feature, Cloud rebuild does not retain personal files, settings, or applications, necessitating independent restoration of these elements. Users can test Cloud rebuild with the latest Windows 11 insider build (Preview Build 26300.8772 or higher) by navigating to Settings > System > Recovery. The timeline for broader availability is uncertain and depends on testing feedback. Other recovery options include recovery drives, resets, Quick Machine Recovery, and a preview feature called Point-in-Time restore.

You can soon restore Windows 11 from scratch even if it can’t boot up

Microsoft is previewing a recovery tool called Cloud rebuild for Windows 11, which allows for a clean reinstallation of the operating system even if it fails to boot. This tool automatically downloads the latest updates and drivers, eliminating the need for manual installations after recovery. Unlike the existing "Reset this PC" feature, Cloud rebuild does not retain personal files, settings, or applications, requiring users to restore these independently. To use Cloud rebuild, users need the latest Windows 11 insider build (Preview Build 26300.8772 or higher) and must follow specific steps in the Windows Recovery Environment. The timeline for broader availability of Cloud rebuild is uncertain, depending on ongoing testing and feedback. Other recovery options in Windows 11 include recovery drives, reset functions, Quick Machine Recovery, and a testing feature called Point-in-Time restore.

Logical replication improvements in Amazon RDS for PostgreSQL 18

PostgreSQL logical replication has operational challenges, such as the absence of generated columns in the replication stream, replication conflicts causing apply worker halts, and lingering replication slots consuming write-ahead log (WAL) files. PostgreSQL 18 introduces enhancements to address these issues, including the ability to include STORED generated columns in the replication stream with a new publication parameter, detailed conflict counters in pg_stat_subscription_stats, automatic invalidation of idle replication slots, and the ability to toggle two-phase commit settings on live subscriptions. To set up a test environment, two PostgreSQL 18 instances (one publisher and one subscriber) are required, along with an EC2 instance for executing commands. The publisher and subscriber must have specific configurations for logical replication, including enabling logical replication and setting appropriate parameters. PostgreSQL 18 allows the replication of STORED generated columns by using the publish_generated_columns parameter. The subscriber must define these columns as regular columns. The new version also enhances conflict monitoring by providing detailed counters for different types of replication conflicts. Parallel streaming is now the default behavior for subscriptions, improving efficiency. The two-phase commit feature can now be modified on existing subscriptions without needing to recreate them. PostgreSQL 18 also introduces automatic cleanup of idle replication slots, which can be configured to invalidate unused slots after a specified duration. Considerations for implementation include ensuring that the subscriber's column types match those of the publisher for generated columns, the requirement for track_commit_timestamp for certain conflict counters, and the fact that sequences are not replicated. Cleanup of replication resources is recommended after testing to prevent unnecessary costs and WAL accumulation.

Task Bar Hero class tier list and the best team compositions for idling your way through the endgame

The author has spent over 300 hours playing Task Bar Hero and created a tier list based on their experience. The tier list is as follows: - S-Tier: Ranger - A-Tier: Priest - B-Tier: Hunter, Sorcerer - C-Tier: Slayer - D-Tier: Knight Key insights include that Ranger is the best class, Priest is versatile as both tank and healer, and Slayer is preferred over Knight. For team composition, a three-man team is recommended for early to mid-game, transitioning to a solo Ranger strategy for higher difficulty. The best team configurations include: 1. DPS Heavy Team: Priest (Tank/Healer), Ranger (DPS), Sorcerer (AoE-heavy DPS) 2. Holy Trinity Team: Slayer (Tank), Priest (Healer/Off-Tank), Ranger (DPS) Additional tips include acquiring Runes of Command for leveling heroes, securing the Rune of Awakening for skill access, focusing on attack damage runes, and using the Rune of Brevity for efficient grinding.

7 Habits That Are More Important Than Using Antivirus on Your Phone

Antivirus software was once standard on personal computers, but modern smartphones have evolved with enhanced security measures from Apple and Google, making them less vulnerable to traditional malware. Smartphones isolate applications, allowing them only to access user-permitted information, and if a malicious app infiltrates, it faces significant challenges due to built-in defenses. Apple requires thorough vetting of apps through the App Store, which enhances security but limits antivirus capabilities. Android allows sideloading apps from outside the Google Play Store, which introduces risks but also includes built-in security features like Google Play Protect and regular updates. Despite these advancements, smartphones can still be compromised, and cybercriminals increasingly target user accounts through phishing tactics rather than malware. Security experts recommend focusing on phishing awareness, strong passwords, and two-factor authentication. For enhanced security, users should keep devices updated, download apps from official sources, review app permissions, use strong passwords, utilize a password manager, enable two-factor authentication, and be cautious with unexpected communications. While most users may not need antivirus apps, those who frequently sideload or download from unfamiliar sites may benefit from additional security tools.
