German healthcare aims to replace faxes and phones with secure mess…

Germany's healthcare system is introducing TI-Messenger, an encrypted messaging service overseen by Germany’s National Digital Health Agency, Gematik, to enhance communication among patients, healthcare professionals, and insurance companies. This service aims to replace traditional communication methods like faxes and phone calls, with initial trials showing significant time savings for medical staff. TI-Messenger, based on the Matrix open network technology standard, is designed to allow secure communication across health institutions while maintaining data control. As of July 15, 2025, it became accessible to all German citizens with public health insurance. A trial in Hamburg demonstrated that pharmacists significantly reduced phone calls by using TI-Messenger. There are two versions of the service: TI Messenger ePA for citizens and TI-Messenger Pro for healthcare professionals, which has not yet seen widespread adoption. Challenges in user adoption exist, with potential solutions including financial incentives and simplified onboarding processes. Future developments may lead to automated responses and improved communication practices, with hopes for collaboration with other European countries using similar technologies.

Senator Wyden Urges FTC to Probe Microsoft for Ransomware-Linked Cybersecurity Negligence

U.S. Senator Ron Wyden has urged the Federal Trade Commission (FTC) to investigate Microsoft for "gross cybersecurity negligence" linked to ransomware attacks on critical U.S. infrastructure, particularly in healthcare. Wyden's concerns were highlighted in a letter to FTC Chairman Andrew Ferguson, referencing a ransomware attack on Ascension that compromised personal and medical information of approximately 5.6 million individuals. The breach was initiated by a contractor clicking a malicious link on Microsoft's Bing, leading to exploitation of insecure default settings in Microsoft software. Wyden criticized Microsoft's use of the outdated RC4 encryption technology, which is vulnerable to attacks, and noted that Microsoft's software does not enforce a minimum password length for privileged accounts. Microsoft plans to phase out support for RC4 and implement additional security measures in future updates. The scrutiny follows previous criticisms of Microsoft's cybersecurity practices, including a report from the U.S. Cyber Safety Review Board.

Scaling AI Inference at the Edge With Distributed PostgreSQL

Data is crucial for artificial intelligence, especially for inference workloads used in real-time decision-making across various platforms. Traditional centralized cloud-based AI inference struggles with demands for low latency and high availability, particularly in applications like autonomous vehicles and healthcare. Shifting AI inference to the edge reduces latency, enhances data privacy, and lowers bandwidth costs. Antony Pegg emphasizes the need for a multi-master active-active architecture that allows read and write operations at any node, ensuring data synchronization and high availability. Misconceptions about edge AI include beliefs that edge hardware can't handle AI workloads, that edge inference is limited to low-stakes use cases, and that centralized systems are necessary for data integrity. The shift to distributed inference can lead to reduced latency, faster insights, and lower costs, while supporting data compliance with regulations. Companies are adopting distributed PostgreSQL solutions with multi-master architecture for low latency and high availability. Enquire AI is an example of a company that improved performance and compliance by transitioning to pgEdge Cloud. This architecture allows for consistent data availability and supports scalable AI solutions at the edge.

Microsoft rolls out Windows security changes to prevent another CrowdStrike meltdown

Last summer's CrowdStrike incident caused significant disruptions in healthcare, banking, and air travel, resulting in billions of dollars in damages. In response, Microsoft held a security summit with experts from CrowdStrike and other firms to address vulnerabilities. Microsoft announced Safe Deployment practices and architectural changes to enhance Windows security, including relocating third-party security drivers from the Windows kernel to user space. This change aims to reduce risks associated with kernel-level flaws. Upcoming features in Windows 11 24H2 include a streamlined crash report process, replacing the Blue Screen of Death with an "unexpected restart" screen, and a quick machine recovery (QMR) capability to automate fixes during outages. Additionally, Windows Autopatch will allow network administrators to deploy updates with fewer required restarts for Windows 11 Enterprise PCs, limiting them to once every three months.

Achieve up to 1.7 times higher write throughput and 1.38 times better price performance with Amazon Aurora PostgreSQL on AWS Graviton4-based R8g instances

Upgrading to Graviton4-based R8g instances with Aurora PostgreSQL-Compatible 17.4 in an Aurora I/O-Optimized cluster configuration results in significant performance improvements. The new instances provide up to 1.7 times higher write throughput, 1.38 times better price-performance, and reduce commit latency by up to 46% on r8g.16xlarge instances and 38% on r8g.2xlarge instances compared to Graviton2-based R6g instances. The Amazon Aurora PostgreSQL-Compatible Edition now supports AWS Graviton4-based R8g instances and PostgreSQL 17.4, which introduces performance enhancements for I/O-Optimized configurations, optimizing write operations and batch processing. R8g instances offer up to 192 vCPUs and 1.5 TB of memory, supporting larger configurations and providing up to 50 Gbps of network bandwidth. PostgreSQL 17 includes vacuum improvements, eliminates the need to drop logical replication slots during upgrades, and expands SQL/JSON standards. Aurora PostgreSQL-Compatible separates compute from storage, enabling independent scaling and maintaining six-way replication for durability, while processing changes as log records to reduce I/O operations. Performance benchmarks using HammerDB show improvements in throughput and commit latency across various workloads. For small workloads on 2xlarge instance size, throughput increased by 50.25% and commit latency improved by 33.87%. For medium workloads on 16xlarge instance size, throughput increased by 30% and commit latency improved by 17.44%. The most significant performance benefits arise from combining hardware upgrades from Graviton2 to Graviton4 with database engine upgrades from PostgreSQL 15.10 to 17.4. For small workloads, throughput increased by 70% and commit latency improved by 38.71%. For medium workloads, throughput increased by 70% and commit latency improved by 46.67%. Cost efficiency is also enhanced, with a 38% improvement in price performance and a 61.26% improvement in price-performance ratio when comparing Graviton2 and Graviton4 instances. Reserved Instances for Graviton4-based R8g instances offer additional cost-optimization opportunities.
