Amazon Lex is a service for building natural language conversational interfaces using voice and text into your application. Earlier this year, we launched an enhanced V2 management console and APIs. The V2 API makes it easier for bot developers to add new languages to a bot and also deliver natural conversational experiences such as wait and continue (“Can you wait while I get my credit card?”). Today, we introduce tooling to automate migration of bots from Lex V1 Console to the Lex V2 Console. The migration tool uses existing intents and slot types to create corresponding resources in the Lex V2 Console.

Image Builder components, which are a set of documents that enable image customization in EC2 Image Builder, now support parameters as an input in the image build process. You can now reuse your existing component investments in EC2 Image Builder to create different custom images by easily passing component parameters, such as installation directory or software version, in the image recipe.

Amazon Lightsail now provides you with the ability to store your static content such as images, videos or HTML files in an object storage that can be used for your websites and applications. Lightsail object storage can be associated to your Lightsail CDN distribution with a few simple clicks, making it quick and easy to accelerate the delivery of your content to a global audience. It can also be used as a low cost, secure backup solution. Lightsail object storage comes with the same predicable pricing as its other offerings with three different flat rate bundles starting at $1/month.

Amazon Kendra is an intelligent search service powered by machine learning, enabling organizations to provide relevant information to customers and employees, when they need it.

Starting today, you can use Elliptic Curve Digital Signature Algorithm (ECDSA) P256 certificates to negotiate HTTPS connections between your viewers and Amazon CloudFront. As noted by NIST , ECDSA certificates can provide comparable security strength with smaller key sizes than RSA. As a result, conducting TLS handshakes with ECDSA certificates requires less networking and computing resources making them a good option for IoT devices that have limited storage and processing capabilities.

AWS Certificate Manager (ACM) now allows you to import Secure Sockets Layer/Transport Layer Security (SSL/TLS) X.509 certificates of additional key types and key sizes, including Elliptic Curve Digital Signature Algorithm (ECDSA) and RSA 3072 and 4096 keys and bind them with integrated services like Amazon CloudFront and Application Load Balancer. Previously, you could use AWS Identity and Access Management (IAM) to import and use these certificate types as ACM only supported usage of imported RSA 1024 or RSA 2048 key certificates.

The AWS Well-Architected Tool (AWS WA Tool) now offers the ability for customers and AWS Partners to mark individual best practices as not applicable during their workload review.

AWS Directory Service for Microsoft Active Directory, also known as AWS Managed Microsoft AD, and AD Connector are now available in the AWS Asia Pacific (Osaka) Region.

Having thought up and simulated a drive circuit for the synchronous rectifier in a Cuk converter, I thought I would wrap it all up and apply the things I learned to the original circuit – a high-side driver for a buck converter (see diag below). And here it is, on the right, with the added pnp …

The US is veering back to the net neutrality stance of the Obama days reflecting presumably, that a more democratic internet is what the Democratic Party should be about. President Joe Biden has signed an executive order suggesting that the FCC re-adopts the net neutrality rules which it scrapped in December 2017. The executive order …
