The database that refused to die: How Postgres survived its own creators

Postgres, originally developed by Michael Stonebraker in the early 1980s, is an open-source database system that evolved from Ingres. It was designed to handle complex data types and introduced user-defined data types, operators, and functions, leading to the support for abstract data types (ADTs). The initial commercialization of Postgres occurred through a startup named Illustra, later acquired by Informix. In 1995, graduate students Andrew Yu and Jolly Chen revived Postgres, transitioning it from QUEL to SQL, resulting in Postgre95, which evolved into PostgreSQL. Today, Postgres is one of the most popular database systems globally, known for its extensibility and high code quality. However, it currently lacks features like file-level encryption (TDE), which are standard in commercial systems, relying instead on the operating system for encryption. Efforts to implement TDE have faced challenges due to the complexity of required code changes.

Google reveals new timeline for Android’s app sideloading changes

Google is rolling out a new system service for Android devices to enhance app sideloading safety, starting this month. In July, the Android Developer ID Status API and early access to the Android Developer Console API will be introduced globally, along with limited distribution accounts for students and hobbyists. By August, these accounts and the new API will be fully launched. The developer verification protections will take effect by September 30 in Brazil, Indonesia, Singapore, and Thailand, requiring app registration for participating app stores. Options for sideloading unregistered apps will still be available through Android Debug Bridge (ADB). By 2027, Google plans to expand the developer verification requirement globally. Developers in the initial countries must complete the verification process by September.

Google Sets Sept. 30 Deadline for Android Developer Verification in Four Countries

Google will implement Android developer verification on September 30, 2026, in Brazil, Indonesia, Singapore, and Thailand. Certified Android devices will block installations of apps from unverified developers, affecting both Google Play and major device-maker app stores. Starting June 2026, the Android Developer Verifier will ensure apps are associated with verified developers before installation. Unregistered apps will not install via standard methods post-September 30 but can be sideloaded through a complex process. Developer registration began in March, requiring legal identification and app ownership verification. Google aims to combat malware with this initiative, which has faced backlash from open-source advocates like F-Droid and the Keep Android Open campaign. The global rollout is set for 2027, with ongoing concerns about appeals processes and the impact on pseudonymous developers.

PC Hand-Drawn 2D Survival Horror Game Announced for Consoles

Moonlight Pale is an indie survival horror game that has transitioned from a PC-exclusive project to a multi-platform release due to high pre-order demand. The developers plan to release the game on consoles, including Nintendo Switch, PlayStation 4, PlayStation 5, and Xbox Series X/S. Initially crowdfunded, the game surpassed its Kickstarter goal of ,566, raising over 0,000, which allowed the team to unlock stretch goals, including console ports and a physical edition for PS5 and Nintendo Switch. The game is set in a late 1800s female seminary, where players control Juliette, who follows the ghost of her deceased cat. Development began in December 2025, with foundational systems programmed, the full script completed, and voice lines recorded for the first two chapters. The launch window is targeted between Q4 2026 and Q1 2027, with the Kickstarter campaign ending on July 4, 2026.

Google sets timeline for Android developer verification enforcement

Android's developer verification initiative will officially roll out on September 30, 2026, initially targeting users in Brazil, Indonesia, Singapore, and Thailand. Developers in these regions must complete the verification process by the deadline. Participating app stores, including Google Play and others, will begin verifying app installations, with a global implementation planned for 2027. The initiative aims to enhance security by linking apps to verified identities. Google is introducing new APIs to facilitate app registration, including the Android Developer ID Status API and the Android Developer Console API, which will support OAuth delegation for third-party platforms. A new system service will be installed on most Android devices to verify developer registrations later this year. The Android Developer ID Status API is set for global launch in July 2026, with early access to the Android Developer Console API. Limited distribution accounts for students and hobbyists will launch globally in August 2026. Starting September 30, 2026, only apps registered by verified developers will be allowed for installation and updates on certified Android devices, although unregistered apps can still be sideloaded. Google has reported that over 99% of Play developers have completed the verification process, and developers can check their verification status in the Play Console.

India’s solution to entrance exam fraud: A temporary ban on Telegram

On June 13, 2026, the National Students Union of India (NSUI) held a protest in Hyderabad against alleged exam paper leaks related to the National Eligibility-cum-Entrance Test (NEET). The Indian government temporarily blocked access to the messaging platform Telegram to combat exam fraud, with the National Testing Agency (NTA) announcing the ban will last until June 22 and disabling the message editing feature until June 30. The NEET-UG exam was canceled on May 12, affecting approximately 2.2 million students, following allegations of a paper leak. Telegram channels were found soliciting payments for leaked exam papers, while the NTA denied any papers were available outside secured channels. Political ramifications included calls from opposition leader Rahul Gandhi for the resignation of Education Minister Dharmendra Pradhan. The Cockroach Janta Party organized protests nationwide demanding accountability for the examination discrepancies.

India Blocks Telegram Access Ahead of Medical School Retest Amid ‘Fake Leak’ Scandal

The Ministry of Electronics and Information Technology in India has imposed a week-long ban on the messaging app Telegram amid a scandal related to the National Eligibility cum Entrance Test (NEET). This decision, enacted under the Information Technology (IT) Act, aims to protect national integrity and sovereignty, following significant irregularities in the original exam held on May 3. The National Testing Agency (NTA) invalidated the initial exam after discovering question leaks, and the upcoming retest is scheduled for June 21. The ban also includes the disabling of Telegram's 'message editing' feature until June 30. Despite the NTA's assurances that no questions have leaked for the retest, concerns about organized cheating groups using Telegram to spread misinformation persist. Pavel Durov, Telegram's CEO, criticized the ban for impacting millions of users without addressing underlying issues. Protests demanding the resignation of Education Minister Dharmendra Pradhan have occurred, and the case has been referred to the Central Bureau of Investigation (CBI), which has arrested approximately 11 individuals based on preliminary findings of leaked questions in the exam.
