From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley and was advised to focus on analytics rather than OLTP databases, which were considered solved. This led to the creation of Apache Spark and Databricks. However, during the development of Databricks, it was found that OLTP databases were not solved problems; they were difficult to scale and fragile. This realization led to the development of Lakebase, a serverless Postgres database designed with modern technology. Lakebase architecture separates the write-ahead log (WAL) and data files into independent, scalable services. The WAL is externalized to a service called SafeKeeper, which uses Paxos-based replication for durability, while data files are managed by PageServer, which stores them in cloud object storage. This design addresses challenges such as data loss, scaling, and performance interference between transactional and analytical workloads. Lakebase maintains compatibility with Postgres, offers unlimited storage, serverless compute, durable writes, and simpler high availability. It also introduces LTAP (Lake Transactional/Analytical Processing), which allows both transactional and analytical processing to operate on a single data copy in real time, eliminating the need for separate data copies and reducing costs. LTAP utilizes a unified storage layer that allows data to be materialized in both row and columnar formats, optimizing it for both transactional and analytical workloads. The system ensures that analytics can access the most current data without affecting transactional performance by using a log sequence number (LSN) to retrieve the latest changes. Unlike traditional CDC approaches, LTAP requires no explicit table replication, as all data is stored in a single governed copy. This architecture circumvents common issues faced by hybrid transactional/analytical processing (HTAP) systems, such as incomplete feature sets, lack of ecosystem support, and performance contention. The Lakebase architecture has unlocked capabilities like unlimited storage, elastic compute, durable writes, and instant branching, with ongoing developments anticipated in the future.

Why Antivirus Is No Longer Just About Virus Protection

Antivirus software has evolved from focusing solely on detecting and eliminating computer viruses to providing comprehensive digital security solutions. The modern threat landscape includes advanced persistent threats, ransomware, phishing schemes, fraud apps, and AI-enabled cyber threats, necessitating a broader approach to cybersecurity. Current digital security systems must detect behavioral anomalies, protect user identities, monitor network activity, identify scam links, and provide multi-layered protection across various platforms. Contemporary antivirus solutions now incorporate AI-based threat detection, cloud intelligence, web protection, email security, identity protection, and ransomware monitoring, reflecting a shift from reactive measures to proactive prevention. Users are now active holders of digital identities, and antivirus software is expected to safeguard their entire digital lives.

Google App Update: A Stunning Gemini AI Upgrade For Mac Users

Google is developing a feature that allows Android users to remotely command and monitor AI workflows on their Macs through the Android Google app. This feature is linked to Gemini Spark, Google's AI agent, and includes a "new thread" system to prevent data leakage. The upgrade aims to create a cross-platform ecosystem for Android users to utilize AI capabilities on Apple-silicon Macs. The feature, internally codenamed "Robin," requires Gemini for macOS to be installed on Apple-silicon devices and allows users to perform tasks like summarizing PDFs or triggering scripts remotely. This functionality is currently exclusive to Mac users, providing them an advantage over Windows users who lack a standalone Gemini desktop client. The Gemini Spark AI framework is still in an experimental stage, and its performance on macOS has yet to be fully validated.

A critical Windows 11 and Windows 10 flaw turns Microsoft Defender into a hacker’s best friend

Chaotic Eclipse, also known as Nightmare-Eclipse, bypassed Windows 11's BitLocker security using a USB stick and claimed Microsoft left a backdoor in the system. Following this, Microsoft patched three zero-day exploits named YellowKey, GreenPlasma, and MiniPlasma. Nightmare-Eclipse then revealed another zero-day vulnerability called RoguePlanet, which affects Microsoft Defender on Windows 10 and 11, potentially allowing attackers full control over compromised systems. Microsoft is tracking this vulnerability as CVE-2026-50656 and is working on a security update. Nightmare-Eclipse provided a proof-of-concept exploit and described it as a race condition with variable success rates. Microsoft has promoted Windows Defender as adequate for most users but acknowledged that third-party tools can offer additional protection. The company initially threatened legal action against Nightmare-Eclipse but later decided not to pursue lawsuits against researchers sharing their findings.

Windows Defender ‘BlueHammer’ vulnerability now exploited as part of malware campaigns — CISA issues warning despite patch release on April 14

A race condition vulnerability in Windows Defender, known as BlueHammer, has been exploited by the hacker Nightmare Eclipse, allowing attackers to gain SYSTEM user access. Microsoft released a patch for this vulnerability on April 14, but the Cybersecurity and Infrastructure Security Agency (CISA) has flagged it as actively exploited in ransomware campaigns. The average time to apply critical OS patches across Windows 10 and 11 is now 127 days, with enterprise environments averaging 76 days. Estimates suggest that 15% to 26% of Windows 10 machines remain unpatched, with a conservative estimate of 20% translating to one in five machines being vulnerable. Microsoft has extended security updates for Windows 10 until October 14, 2027, but public awareness of the updates remains low.

Microsoft Reveals Windows Setting to Safely Remove USB Drives and Prevent Data Loss

Removing a USB drive from a port without using the “safely remove” option is generally acceptable on many Windows computers, depending on the policy for the external device. Microsoft provides two main options for removable drives: quick removal and better performance. Under the quick removal policy, users can disconnect the device without the “Safely Remove Hardware” process, although this may reduce system performance. Since Windows 10 version 1809, quick removal has been the default policy for external devices. However, users must ensure that all operations, such as copying or formatting, are completed before removal. The better performance policy requires users to use the safe removal option to prevent data loss, as it allows write caching. Failing to do so increases the risk of data loss if the drive is disconnected while Windows is still processing writes. The highest risk of data loss occurs when the drive is removed while Windows or an application is engaged in file operations. The safe removal icon serves as a confirmation that the drive is not in use, helping to prevent accidental ejection during active processes. Users can check the flash drive policy by accessing the device properties in Disk Management. The chosen setting may persist upon reconnection to the same computer port, leading to different experiences for users with similar drives. To minimize data loss, it is recommended to wait for operations to finish and use safe removal when uncertain about the drive's status.

Here’s How Google Meet Works On Android Auto While You’re Driving

In 2026, Android Auto will introduce features to improve the driving experience, including native meeting controls for Google Meet integrated into the car's infotainment system. Users must update the Google Meet app and connect their phone to access a dedicated Meet icon, which includes a Scheduled tab for upcoming meetings and a History tab for recent contacts. The system allows seamless handoff of audio and control between the phone and car when entering or exiting the vehicle. The Google Meet experience in Android Auto will be audio-only, disabling video feeds and interactive functions like polls and chat to prioritize driver safety. Essential controls such as mute/unmute and hang up will be available on the car's display, and the app can automatically mute the microphone to reduce background noise. Users must pull over to access visual elements on their phone.
