A SQL HEURISTIC: ORS ARE EXPENSIVE

OR clauses in SQL queries can be much slower than AND clauses due to how query planners use indexes. When using OR, the database might resort to less efficient strategies like merging separate filtered results or performing a full table scan. Rewriting queries to use AND clauses, often by using unions or restructuring the schema, can improve performance. Common schema issues that lead to needing OR clauses can be addressed by creating secondary tables or using an extension table pattern.

CYBERATTACK ON CO-OP LEAVES SHELVES EMPTY, DATA STOLEN, AND $275M IN LOST REVENUE

The DragonForce cybercrime group's April attack on UK retailer Co-op resulted in $275 million in lost revenue, weeks of empty shelves, and the theft of data from 6.5 million members, including names, contact details, and dates of birth (though passwords and payment information were not compromised). Co-op initially claimed no customer data was affected, but later confirmed the breach after hackers contacted executives via Microsoft Teams and phone, claiming to possess data on 20 million membership scheme participants. In July, the UK's National Crime Agency arrested four suspects aged 17-20 in London and the West Midlands on charges including Computer Misuse Act offenses, blackmail, money laundering, and organized crime participation, with DragonForce also claiming responsibility for attacks on M&S and an attempted breach of Harrods.

OPENAI WILL REPORTEDLY RELEASE A TIKTOK-LIKE SOCIAL APP ALONGSIDE SORA 2

OpenAI is preparing to release a standalone social app powered by its Sora 2 video model. The app will reportedly closely resemble TikTok but only feature AI-generated content. There will be no option for users to upload photos or videos. Users will be limited to generating 10-second-long clips. They will be able to create videos using their likeness - and receive a notification whenever their likeness is used by someone else. The app will refuse to generate some videos due to copyright restrictions.

CHINA'S OYSTER-INSPIRED ‘BONE GLUE' BONDS FRACTURES, CAN REPLACE METAL IN SURGERY

Bone-02 is a new kind of medical adhesive created by a team of Chinese researchers. It is designed to repair broken bones quickly without the need for metal plates, screws, or big surgeries. The glue can be injected directly into a fracture site to help speed up bone repair, bonding bone fragments together in two to three minutes, even in blood-rich areas. The researchers were inspired by oysters, which have a remarkable ability to attach to hard surfaces in harsh environments. This is due to a special protein-rich adhesive that works in wet, salty, and constantly moving conditions, forming a tough bond that resists both pressure and erosion.

6,100-QUBIT PROCESSOR SHATTERS QUANTUM COMPUTING RECORD

Physicists from the California Institute of Technology have built a quantum computing array containing 6,100 qubits, well above the thousand or so qubits previous systems contain. They used cesium atoms as their qubits, trapping them in place with a complex system of lasers that act as tweezers to keep the atoms as stable as possible. Large arrays allow for better error correction, which helps to overcome the inherent fragility of qubits by providing a surplus to double-check machine operations.

FORK YEAH: VALKEY 9 SHARPENS EDGE AGAINST REDIS

Valkey, which was forked from Redis in April last year, is set to release its ninth iteration next month. The update promises improved resource optimization and availability. It will allow multiple logical databases in cluster mode, enabling developers to combine many different applications using the same cluster. Valkey 9 also promises unified auto-failover configuration for high availability, regardless of deployment choices, so clusters stay consistent from development to staging to production. It has a safe shutdown mode, so a shutdown command does not pull the plug on production without a deliberate, confirmed action.
