In addition to LEDs and LED displays by Liteon, distributor TME has announced a variety of optoelectronic components. The components are made for galvanic isolation up to the high kV range by enclosing a transmitting LED and a phototransistor in a single package for the signal to be transmitted optically between them. For use in …

Wurth has written an application note about balancing series-connected supercapacitors. There are other similar resources on the web, but this one stands out as, alongside the usual resistor, Zener and op-amp circuits, it includes balancing using Advanced Linear Devices’ unusual regulating mosfets, and ADI’s LTC3128 charger and balancer that flips power from the most to the …

You can now use AWS PrivateLink to privately access Amazon MemoryDB for Redis from your Amazon Virtual Private Cloud (Amazon VPC). AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises networks, without exposing traffic to the public internet and securing your network traffic. The Amazon MemoryDB for Redis API  supports AWS PrivateLink in all regions where Amazon MemoryDB for Redis is available. For a complete list, see supported regions .

Amazon RDS for MariaDB now supports MariaDB version 10.6. This release introduces multiple MariaDB features to enhance the performance, scalability, reliability and manageability of your workloads, including:

• MyRocks storage engine: You can use the MyRocks storage engine with RDS for MariaDB to optimize storage consumption of your write-intensive, high-performance web applications.
• IAM integration: You can now configure AWS’s Identity and Access Management (IAM) with your Amazon RDS for MariaDB instances to simplify access management of your AWS resources. With IAM, you can manage user access to all AWS resources from a single location and avoid issues caused by out-of-sync permissions on different AWS resources.
• Flexible Upgrades: You can upgrade to RDS for MariaDB 10.6 from any prior MariaDB major release (10.2, 10.3, 10.4, 10.5) in a single step. You can also take a snapshot of an existing MySQL 5.6 or 5.7 instance and use the RDS snapshot restore feature to convert it into a MariaDB 10.6 instance.
• Delayed replication: You can now set a configurable time period for which a read replica lags behind the source database, as a disaster recovery strategy. In a standard MariaDB replication configuration, there is minimal replication delay between the source and the replica.
• Oracle PL/SQL compatibility: With an increased set of PL/SQL compatibility functions (e.g. ROWNUM(), TO_CHAR(), ADD_MONTHS()), you can migrate your legacy Oracle stored procedures as-is to RDS for MariaDB 10.6.
• Atomic DDL: Your DDL statements will now be crash-safe with RDS for MariaDB 10.6. CREATE TABLE, ALTER TABLE, RENAME TABLE, DROP TABLE, DROP DATABASE and related DDL statements are now atomic. Previously a crash during a DDL operation could lead to undetermined results and introduce errors during replication. With atomic DDL, either a DDL operation is either fully done or not done at all. Therefore, recovery from crashes during DDL operations are deterministic and binlog remains consistent across any server crashes.
• Other enhancements: JSON_TABLE function for transforming JSON data to relational format within SQL, faster empty table data load with Innodb, new sys_schema for analysis & troubleshooting, optimizer enhancement for ignoring unused indexes and performance improvements.

You can now use AWS PrivateLink to privately access Amazon ElastiCache from your Amazon Virtual Private Cloud (Amazon VPC). AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises networks, without exposing traffic to the public internet and securing your network traffic. The Amazon ElastiCache API supports AWS PrivateLink in all regions where Amazon ElastiCache is available. For a complete list, see supported regions .

Amazon Keyspaces (for Apache Cassandra)—a scalable, highly available, and fully managed Cassandra-compatible database service— now is in scope for FedRAMP Moderate compliance to help you run highly regulated Cassandra workloads more easily.

Amazon FSx for OpenZFS now supports full-copy volumes to make it easier to clone and experiment with your data, enabling you to quickly capture the results of your cloning-based testing for long-term use.

You can now build custom connectors for Amazon AppFlow using the Custom Connector Software Development Kit (SDK). With the SDK, you can connect to private APIs, on-premise proprietary systems, and other cloud services by adding to AppFlow’s library of connectors. It is open source and available for both Java and Python.

You can now use Recycle Bin for Amazon Machine Images (AMIs) to recover from accidental deletions to meet your business continuity needs. Previously, you could not recover AMIs if you accidentally deregistered them. With Recycle Bin, you can specify a retention time period and recover a deregistered AMI if needed, before the expiration of the retention period. A recovered AMI would retain its attributes such as tags, permissions, and encryption status, which it had prior to deletion, and can be used immediately for launches. AMIs that are not recovered from the Recycle Bin are permanently deleted upon expiration of the retention time.
