MongoDB talks up its AI chops by talking down PostgreSQL

MongoDB has criticized PostgreSQL for its scalability issues with AI workloads, as stated by CEO Chirantan Desai. He noted a customer's switch from PostgreSQL to MongoDB due to these challenges. Following MongoDB's positive earnings report, its share price rose by 23%. The company reported .3 million in revenue for Q3 FY 2026, a 19% increase from the previous year, while operational losses decreased from [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: MongoDB's Competitive Stance in the Evolving Database Landscape In a bold move amidst the ever-changing database ecosystem, MongoDB has taken a critical stance against its rival, PostgreSQL, asserting that the latter struggles with scalability in the context of AI workloads. CEO Chirantan Desai leveraged the recent positive earnings results for the quarter ending October 31 to voice these concerns, particularly as PostgreSQL has surged in popularity among developers in recent years. During a discussion with investment analysts, Desai emphasized MongoDB's capabilities as a foundational platform for AI applications, although he acknowledged it was premature to declare it the definitive choice. He highlighted a recent case where a customer transitioned from PostgreSQL to MongoDB, citing scalability issues as the driving factor behind their decision. Following the announcement, MongoDB's share price experienced a notable 23% increase on Tuesday morning, buoyed by revenue figures that surpassed investor expectations. The company reported 8.3 million in revenue for Q3 FY 2026, marking a 19% increase compared to the same quarter last year, while operational losses narrowed from .9 million to .4 million. Desai's remarks may stem from PostgreSQL's growing influence, a relational database system that has been around since the 1980s and has recently gained traction in the developer community. By 2023, PostgreSQL emerged as the most favored database among professional developers, as indicated by the Stack Overflow survey. This shift followed PostgreSQL's ascent in the DB-Engines ranking since 2016, which evaluates databases based on various metrics, including online discussions and job postings. In response to Desai's claims, Barclays Bank analyst Raimo Lenschow posed a question regarding developer engagement in light of the "PostgreSQL narrative" prevalent in Silicon Valley. Desai countered by referencing a "super-high growth AI company" that faced scalability challenges with PostgreSQL, ultimately opting for MongoDB. PostgreSQL's rise can be attributed to the robust database services offered by major cloud providers, which have faced scrutiny over reliability. Nevertheless, several PostgreSQL-compatible services with distributed architectures, such as CockroachDB, pgEdge, and YugabyteDB, have emerged to address these reliability concerns. Moreover, PlanetScale, known for its distributed MySQL service built on the YouTube-developed Vitess, has recently introduced a PostgreSQL service. Microsoft has also entered the fray with its new distributed PostgreSQL database service, HorizonDB, designed to compete with other hyperscaler systems and third-party RDBMS solutions like CockroachDB and YugabyteDB. Microsoft claims that HorizonDB, which offers full compatibility with open-source PostgreSQL, features a new storage layer that enhances performance, scalability, and availability compared to its existing PostgreSQL offerings. This service stands alongside distributed PostgreSQL solutions from Google (AlloyDB) and AWS (Aurora DSQL). In a further twist, Microsoft has developed a document database platform intended to rival MongoDB, built on a relational PostgreSQL backend and utilizing FerretDB as a front-end interface with a document database protocol. Faced with such formidable competition, MongoDB is compelled to defend its platform not solely on the basis of scalability but also regarding its reliability for enterprise workloads—an area where it has long asserted its readiness.

How Letta builds production-ready AI agents with Amazon Aurora PostgreSQL

AI agents benefit from persistent memory, enabling them to recall past interactions and maintain context, which enhances customer experience in scenarios like customer service. The Letta Developer Platform allows developers to create stateful agents with advanced context management features. It supports self-hosting within a virtual private cloud and uses Amazon Aurora PostgreSQL for long-term memory storage. Aurora PostgreSQL offers capabilities such as efficient similarity searches with the pgvector extension, sub-second query latency, and dynamic storage scaling. Letta operates as a persistent service, allowing agents to function independently and scale horizontally using Kubernetes. The platform supports multi-tenancy and includes enterprise features for security and monitoring. To set up an Aurora Serverless cluster for Letta, users must create a database on Amazon RDS, configure security group access, and install the pgvector extension. Letta connects to Aurora using a PostgreSQL connection string. After establishing the connection, users can create agents, send messages, and view agent states and conversation histories stored in Aurora. Letta organizes data in 42 tables, including those for agents, messages, and memory blocks. Users can explore the database schema and examine the structure of stored messages and embeddings. Finally, it is recommended to delete the Aurora cluster and associated resources after completing the integration to avoid charges.

PostgreSQL 13’s Sunset: Why Database Pros Must Upgrade Before the Lights Go Out

Organizations using PostgreSQL 13 must upgrade before its end-of-life on November 13, 2025, as this will result in the cessation of security patches, bug fixes, and official support. Continuing to use an unsupported version exposes systems to vulnerabilities, which can lead to data breaches and compliance challenges. The last minor release for PostgreSQL 13 was 13.21 in May 2025. Upgrading to newer versions, such as PostgreSQL 16 or 17, offers performance improvements and enhanced features. Strategies for upgrading include using tools like pg_upgrade, pg_dump/pg_restore, and logical replication to minimize downtime. Compatibility issues may arise due to deprecated functions in PostgreSQL 13, necessitating code reviews. Managed services like those from Percona can provide support beyond EOL. The costs of not upgrading can be significant, with potential downtime from security breaches often exceeding migration expenses.

Ради игр с торрентов геймеры сверлили Xbox и вставляли пинцет в Nintendo Wii. Самые необычные способы пиратства на консолях

Many methods of console piracy have emerged over time, often exploiting unintentional vulnerabilities in licensed games. For example, the PSP was easily hacked due to flaws in games like Grand Theft Auto: Liberty City Stories and Medal of Honor: Heroes, which allowed users to manipulate save files to gain access to the system. A debug code in Alien: Resurrection for the PS1 enabled users to swap discs without turning off the console. Various makeshift tools have been used for hacking, such as a paperclip to exploit the Nintendo Switch and tweezers to access dormant memory sections in the Wii. The Nintendo 3DS was hacked using a magnet to trick the lid sensor, allowing access to developer mode. The Xbox 360 faced significant modding due to its firmware modification capabilities. A notable method involved drilling into the drive to bypass rewrite protection, known as the "Kamikaze Hack." While piracy methods have evolved, modern consoles have become increasingly secure, with fewer successful hacks reported in recent years. The appeal of piracy has diminished as subscription services and sales provide easier access to games.
