DBtune autonomous optimization blows PostgreSQL bottlenecks away

DBtune, a startup based in Malmö/Lund, Sweden, was founded in 2020 by Dr. Luigi Nardi as a spin-off from Stanford University and Lund University. The company focuses on enhancing PostgreSQL's capabilities through autonomous database optimization technology and has raised .4 million in a seed round from various investors in July 2023, with support from the Wallenberg Foundation and Vinnova. DBtune's technology utilizes agentic AI for optimizing PostgreSQL databases by tuning server parameters, optimizing indexes, and monitoring autovacuum processes. The release of DBtune version 4.0 incorporates machine learning and AI to dynamically adjust server parameters and suggest optimal indexing strategies. The platform identifies and ranks potential index opportunities based on workload and provides recommendations for new indexes and maintenance of existing ones. A case study with Midwest Tape demonstrated a 10.8x performance improvement in database query runtime after employing DBtune for performance tuning. Benchmarking tests showed a transaction throughput increase of 87% during initial optimization, with a further 17% improvement on an already optimized system. Disk I/O activity was reduced by 43%, and WAL generation decreased by 23%. Dr. Nardi emphasizes the need for AI-driven optimization to manage the complexities of PostgreSQL databases and rising cloud costs, suggesting that significant code adaptations will be necessary for achieving fully autonomous PostgreSQL.

Why Your Android Buzzes When Plugging It In (And Why Multiple Buzzes Could Be A Problem)

A faulty connection can cause potential damage to an Android device and reduce charging efficiency. Third-party battery apps may contribute to buzzing sounds during charging. Cleaning the USB port with compressed air and a toothpick can resolve buzzing issues caused by debris. If buzzing persists after cleaning, testing different cables and chargers can help identify the problem. If the issue remains, it may be a hardware problem with the phone itself, necessitating professional repair or DIY attempts. Users can disable charging sounds and vibrations in the settings, but this may reduce feedback on charging status.

PAYLOAD ransomware hijacks Windows Group Policy in encryption-less attacks

A sophisticated PAYLOAD ransomware attack targeted an unnamed manufacturing organization in the Middle East, exploiting vulnerabilities in Microsoft Active Directory Group Policy. The attackers accessed the network through a compromised domain account via FortiGate SSL VPN on April 11, escalated privileges to domain administrator by April 13, and created a malicious Group Policy Object (GPO) named "PAYLOAD." This GPO was linked at the root of the domain, allowing it to affect nearly all domain-joined Windows workstations. The attackers distributed ransom notes, altered desktop images, displayed ransom messages at login, and disabled local administrator accounts. A second GPO, "win Firewall Off," was deployed to disable Windows Firewall across all profiles. The malicious policies activated on April 14 after systems were rebooted, causing widespread disruption. The attackers also exfiltrated data from file servers and published it on the dark web, while Kaspersky found no evidence of Windows file encryption or active malware processes. Recommendations for organizations include monitoring GPO creation, checking for unexpected changes, implementing multi-factor authentication for VPN access, and protecting privileged accounts.

I ran a single command and found more garbage on my Windows 11 drive than Storage Sense cleaned all month

On Windows 11, the Storage Sense feature can reclaim space by cleaning user-level files, such as temporary data, items in the Recycle Bin, files in the Downloads folder, and cached OneDrive copies. It recently reclaimed approximately 1.67GB of space in one morning and a total of 10.2GB over the past month with default settings. Storage Sense only activates when the storage drive is nearing capacity unless the user adjusts the schedule. It can be configured to run daily, weekly, or monthly, and users can set parameters for emptying the Recycle Bin and deleting files in the Downloads folder. However, Storage Sense does not clean the entire drive or access the Windows component store, which holds outdated system files. The component store was found to contain approximately 11.84GB of data that Storage Sense cannot clean up. The total size of the component store is 20.14GB, with a significant portion comprising backups and disabled features. Users may need additional cleaning tools to manage the data that Storage Sense cannot address.

How to recover the Google Maps speedometer on Android Auto: the ultimate trick

The Google Maps speedometer has disappeared for many Android Auto users due to a cache conflict, resulting in the speed overlay vanishing from screens. This issue is linked to internal desynchronization between the mobile app and the car's infotainment system, causing crashes for users. The problem is not due to changes on Google’s servers but rather the accumulation of temporary data that prevents crucial elements from loading correctly. Reports indicate that this issue affects users across various Android versions, including Android 14. A temporary solution involves performing a clean reset of the Google Maps and Android Auto apps by clearing their cache and data. If the problem persists, users may need to check for updates or wait for a fix from Google. Additionally, maintaining updated location permissions and the car’s system is recommended. Waze is suggested as an alternative for speed accuracy during this issue.

Your Phone Can Use Android Auto Without A Car – Here’s How (And Why You Should)

Open Headunit, previously known as Headunit Revived or Headunit Reloaded, is available for .99 and .99 respectively. To use an old tablet as a head unit, purchase and install the app on the device, connect it to a phone using a USB OTG cable, and select the USB connection in the app. Wireless connectivity options are available for both apps, including using a wireless Android Auto dongle, a native Wi-Fi P2P connection, or the third-party app Wireless Helper. Wi-Fi Launcher can be paired with Headunit Reloaded for a similar experience. The Android Auto developer server allows broadcasting a self-hosted server to run Android Auto on a single device. Utilizing Android Auto can enhance productivity by allowing users to read messages, check notifications, and access smart home controls while minimizing distractions. Setting up an old device creatively can enhance a workspace, as virtually any device can serve as a display for the head unit apps.
