Advanced SystemCare 19 Cleaned 3GB Hidden Junk From My PC

The user experienced a slow computer with prolonged startup times and storage shortages despite manual cleanup efforts, including emptying the Recycle Bin and using Windows Disk Cleanup. A deeper system scan revealed hidden junk files such as temporary files, browser cache, and outdated logs. The user then utilized Advanced SystemCare 19 Free, which effectively identified and removed 3GB of junk files, resulting in improved startup speed, program launch times, and overall performance. Advanced SystemCare also includes features like a registry cleaner, large file finder, disk cleaner, and app/extension cleaner, and it serves as a comprehensive system optimization suite with tools for enhancing boot time and protecting privacy. The software does not delete files automatically and should be used alongside antivirus software for complete protection.

Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

Google boosts AlloyDB vector search with HNSW preview

Google has introduced a preview of its columnar engine-accelerated HNSW feature for AlloyDB, enhancing vector search throughput by up to four times for users of the pgvector extension in PostgreSQL. This improvement is aimed at approximate nearest neighbor searches using HNSW across large datasets. AlloyDB utilizes a columnar engine that allows HNSW indexes to reside in memory, improving throughput and recall metrics. In benchmark tests on the GloVe 100 Angular dataset, queries per second increased by approximately 4.2x to 4.9x, with recall improving from about 0.78 to over 0.94 at a throughput of around 350 queries per second. The columnar engine's design bypasses traditional PostgreSQL buffer management bottlenecks, enhancing efficiency during graph traversal. The memory architecture is distinct from basic caching techniques, and the feature requires no changes to application code. Users must enable the columnar engine and index caching flags to utilize this feature. Benchmarks were conducted on an AlloyDB C4A machine with 16 virtual CPUs.

Splitgate studio 1047 Games is laying off more people just a month after releasing its latest game

1047 Games has experienced another round of layoffs, described as the "third wave" by employees on LinkedIn. QA director Igor Krinitskiy and concept artist Jonathan Kuo confirmed their departures due to these layoffs. The studio, known for its hit title Splitgate: Arena Warfare, has struggled with subsequent projects, including the rebranded Splitgate: Arena Reloaded and the recently launched Empulse, which has not achieved significant player engagement and has seen concurrent player numbers on Steam drop below 1,000. Studio CEO Ian Proulx emphasized a focus on gradual growth rather than immediate success.

A new friendslop game is already Steam’s 12th-most wishlisted game a mere week after it was announced

Dear Passengers is a co-op game that has reached the 12th spot on Steam's wishlist chart just one week after its announcement. Players take on the roles of airline crew members managing various tasks while navigating challenges such as turbulence and inclement weather. The game garnered 700,000 wishlists within 36 hours of its trailer release on July 14, surpassing 1.5 million shortly thereafter. The developer, Flexus, faced criticism for edgy humor in character names but clarified that all characters are fictional. A job posting for a 2D Artist sparked speculation about AI use in the game, which the developers denied, stating no AI was used in its creation. The game is scheduled for release in 2026.

One in six Windows PCs still runs Windows 10, and the vulnerabilities are piling up

Approximately 17% of all Windows client devices are still running Windows 10, equating to about one in six machines. Windows 11 accounts for 78% of Windows devices, with third-party trackers indicating it surpassed 70% of desktop share as of February 2026. Official support for Windows 10 ended in October 2025, but Microsoft’s Extended Security Updates (ESU) program will provide patches until October 2027 for eligible devices. A typical Windows 10 device has an average of 1,903 active security vulnerabilities, nearly three times the 652 CVE-tracked flaws found on a Windows 11 machine. 66% of Windows 10 vulnerabilities are classified as "high" or "critical." Small and medium enterprises have 21.4% of their Windows devices still on Windows 10, while larger enterprises have 16.6%. The healthcare and pharmaceuticals sectors have 23% of devices on Windows 10, followed by consumer and retail at 22%, and manufacturing at 18%. Lansweeper is urging organizations to enroll in the ESU program and address reasons for remaining on Windows 10 as 2026 approaches.

LG admits its monitor app installs bloatware via Windows Update, and Microsoft is letting it happen

A growing number of LG monitor users have reported that connecting their devices to Windows systems results in the automatic installation of the LG Monitor App Installer, which prompts users with a McAfee trial advertisement. YouTuber Gamers Nexus found that connecting an LG UltraGear monitor led to the installation of LG's driver package and the LG Monitor App Installer, with the McAfee pop-up appearing 31 times over 32 boots. This automatic installation is facilitated by device metadata, which Windows uses to download associated applications without user notification. Users must be signed into the Microsoft Store and connected to the internet for this to occur, leading to frustrations about transparency. Reports of unsolicited McAfee pop-ups have been shared on platforms like Reddit, with users confirming the app's installation was logged as part of a Windows Update. LG has acknowledged the inclusion of McAfee in their app updates, promoting a free trial, which has raised privacy concerns. The app's rating on the Microsoft Store has dropped to around 1 out of 5 due to user dissatisfaction. Users can prevent automatic installations by adjusting Group Policy settings, while macOS requires manual approval for third-party applications. Neither Microsoft nor LG has formally addressed the concerns regarding silent installations and McAfee pop-ups.
