Note Web gets a voice console with MCP!

Considering this Azure support announcement and this streamlined audio experience goal outline, it was just a matter of time until Note Web development gets to enabling your noteinweb.com account data in most naturally sounding conversation, currently technically possible, powered by your Azure account's Cognitive Services (Azure OpenAI).

There are still a few issues to resolve, like frequent hallucinations when gpt-4o-realtime-preview-2024-12-17 generates Note Web DSL code and attempts to read it out loud (though instructed not to). Another factor is Azure OpenAI Realtime API supports only WebSocket communications. OpenAI's WebRTC Realtime API takes care about audio chunking, encoding and playback and offers better perceived performance on the tested implementations.

Nevertheless, an initial step on the way speaking naturally to Note Web CAIP Agent in your MS Teams and AWS Chime calls, would be Note Web voice console. It would be reachable from Note Web UI menu, next to Profile item. It would be just a couple of clicks to discuss requirements for your cloud solution, review the blueprint Note Web DSL and deploy it to your AWS or Azure accounts. Stay tuned for How-to of Note Web Voice Console!

And yes - you noticed right in the article's title. Just as Bluetooth in Sheldon Cooper's (TBBT) understanding, makes everything better, so does Model Context Protocol in opinions of AI experts nowadays. Note Web would also implement MCP Client and Server capabilities. MCP would be initially offered with Note Web Console.

Mapping Note Web DSL resource types for Azure

There is no direct equivalent to AWS ECS in Azure. Arguably, the closest match to AWS ECS is Azure Container Instances. This article provides details on this matter for Note Web DSL.

Quick walk through on setting up AWS Bedrock Mistral Large 24.02 and Claude 3.5 Sonnet for use with your Note Web CAIP Agent!

While there is an issue with AWS Bedrock Mistral following requirements on generating UI per NW DSL, AWS Bedrock Claude 3.5 Sonnet behaves just as well as via direct Antropic API in a yet earlier How-to screen cast.

Use AWS BedRock FMs with Note Web CAIP Agent

Well, original post name also mentioned "Anthropic Claude 3.5 Sonnet". However, LangChain ZERO_SHOT_REACT_DESCRIPTION agent issues several prompts and quickly exceeds quotas. Claude 3.5 is available in AWS Bedrock only with cross-region inference (via inference profile). Its quota is couple of requests per minute. So Note Web CAIP Agent quickly hits a ThrottlingException, unless single invocation is enough to generate Note Web DSL code. The latter is seldom the case.

Still, having adjusted agentic use in NWCA it is possible to get a deployable and runnable NW DSL as well as Typescript and Ansible code with a single request to AWS Bedrock (at least without any AWS Bedrock quota increase). Check out this quick walk through!

So, stay tuned for update on which AWS Bedrock Foundational Models perform the best for Note Web CAIP Agent tasks.

Explore Azure powers with Note Web! (Cloud Account Tag Configuration)

This How-to screen cast opens series about exploring Azure cloud services with Note Web using hierarchies, filtered lists and diagrams. This How-to series would also introduce to building Note Web DSL applications for Azure. Apart of already presented CRUD applications, we'd also introduce to using Azure AI services for LLM and RAG down the road.

Ask Note Web CAIP Agent if it can help you with setting up your Internal Development Platform!

So you've walked the path from requirements to a cloud solution blueprint. And you know from previous articles and screen casts on this blog, that Note Web assists you throughout this journey. This support is multifaceted:

  • participating in your audio and video calls, providing insights on your mapped in Note Web data (RAG) including solution backlog, design and other documentation
  • suggesting a solution blueprint as Note Web DSL with deployment and component diagrams
  • generating TypeScript/Python/Java code for your microservices as per suggested Note Web DSL blueprint
  • deploying microservices and infrastructure to AWS and Azure
  • analyzing deployment logs to help pinpoint the culprit in case of AWS/Azure resource naming clashes, etc.

You've managed to impress your customers by showing a data management solution discussed on that very same call deployed and running (in your or their AWS or Azure cloud account)!. Albeit form design is currently simplistic, but you can show user journey starting from registration to authentication to manipulating data in SQL and NoSQL backends, with pay-per-request (serverless with AWS Lambda) and provisioned approaches (AWS EKS/ECS).

What if they like presented solution suggestion, but need a few changes? Bingo! If the change is within Note Web DSL code, just modify and re-deploy on that very same call!

Hey, you'd like to change anything in Note Web generated TypeScript/Java/Python/Ansible (soon to be augmented by Terraform and .NET) code, safely stored in your git repositories... Note Web can help you streamline delivery of your git repo changes too! For example, starting with version 11.49 it contributes to your Internal Development Platform by setting up AWS CodePipeline/CodeBuild projects (soon with AWS CodeArtifact support)

Watch this How-to screen cast on overview of Note Web DSL features that Note Web CAIP Agent can use, if asked, to setup build pipelines yet at solution generation and deploy time. Conveniently store your git repository credentials in AWS Secrets Manager, observe your build process in AWS CodeBuild or CodePipeline, manage container images produced by build pipelines in AWS ECR.

Drop an email to Note Web Product Management at support@NoteInWeb.com, if you're interested in building your IDP on GitHub Actions, GitLab CI/CD or Jenkins with Note Web!

Getting model name in LLM prompt response

Previous How-to screen cast would've been way more spectacular if different LLMs used could reliably identify themselves in their responses. . That was not the case. LLM responses to prompt clauses below were mostly correct about provider, but each time varied and were usually wrong about the model:

  • Please include in response name of LLM provider and exact version (used to process this prompt)

Nowadays, GenAI tools usually display service information like counts of tokens processed, session costs, etc. Note Web would also make this info part of UI, at least for subsequent How-to's, especially on topics comparing different LLMs and RAG techniques. For now, it just includes model name in a topmost comment in generated NW DSL code.

Quick glimpse for nice modern compact linux desktop distro, that scales easily

It should be easy to start and stop desktop session. Desktop should be nice, modern and sleek. Installing new tools should be quick and reliable. It should be easy to manage hundreds of concurrent sessions in AWS.

For many reasons, enough for a separate large article, shortlisted Xfce for resource efficiency. Modern looks category favorite is KDE Plasma. Briefly checked for suitability for the use case also were:

  • Fedora 41 - KDE 6.2.1 - KVM input-leap worked ok oob in Wayland session
  • KDE Neon unstable - KDE 6.3 dev - barrier did not work due to Wayland
  • Kubuntu 24.10 - KDE 6.1 - barrier/input-leap worked ok due to default X11

 

Let's see if Note Web CAIP Agent can assist lowering entry level for a few AWS and Azure services, somehow differently than AWS Q and Copilot do it.

AirLLM to run Llama-3.1-Nemotron-70B-Instruct-HF on g4dn.xlarge

Llama-3.1-Nemotron-70B ranks among top on Arena Hard and Alpaca Eval as of October 1, 2024. Sharded model files are approximately 150GB. That lines up to VRAM requirements of couple of 80GB A100. AirLLM runs inference layer-wise, enabling 70B LLama3 on 4GB GPU, 405B on 8GB. However, it is yet not a solution for NoteInWeb.com to offer free tokens alternative to 3rd party LLM providers for inference. It takes a few minutes for a single prompt on g4dn.xlarge...

GenAI Tools Coding gRPC Client-Server, structured text output, OS process control

Note In Web, Inc. continuously broadens Note Web support for deploying NW DSL code to Azure with Terraform. As this post mentions, there will be soon a How-to screen cast on this topic. There is a small backlog of implemented stories and relevant hands-on experience.

Typical tasks considered were adding gRPC client to Scala codebase, building gRPC Java server, generating structured text (eg. scripts), launching and controlling OS processes. There are few words about mileage with Aider architect mode, Cline, SWE-Agent, OpenHands, Amazon Q Developer. Plan is to check Agentless and GitHub Copilot Workspace as well. Drop an email if you find the topic interesting or got ideas for other interesting Java/Python/TypeScript development cases.

Deploying NoteInWeb.com to AWS - part 1 (EKS workloads)

Watch this screencast for a quick walkthrough on how to use Note Web DSL to setup an operational site (actually NoteInWeb.com itself) of the following major elements:

  • AWS EKS Cluster - with basic node group parameters, eg. instance image, type, desired count, volume size
  • AWS EFS - file system to store Note Web file attachments, configurations, etc.
  • 12 AWS Kubernetes services from ECRs, including a gateway, that mount the EFS file system
  • additional configuration items required to enable AWS EKS cluster nodes and pods to use EFS
  • initial image to be unzipped and applied to EFS file system from a file in a bucket

 

This corresponds to legacy Note Web deployment configuration, that relies only on the mentioned AWS services to maintain focus of this screen cast.

Stay tuned for a How-to on using NoteInWeb.com to build an AMI and deploy an auto-scaling group with template based on that AMI. That would conclude the coverage of migrating NoteInWeb.com to AWS (except for finer details, like configuring SSL certificate from ACM, DNS setup with Route53, secrets in AWS Secrets Manager, observability setup and deployment automation - for yet a bit later)

Benefits of OpenAI Realtime API for NW CAIP Agent Audio experiences

As of Note Web version 11.25, NW CAIP Agent is built to reliably identify prompts addressed to it in a multi-party conversation. NW CAIP Agent in video-chat calls, with or without avatar, i.e. audio-only experience, expects keywords to demarcate the prompt, eg. "Note Web, please..." and "Go, Avatar!"

Needless to mention the risks of forgetting the "Open Sesame" keywords, this approach may not seem quite natural in peer-to-peer human-AI conversations.

So, Note in Web, Inc. product management has been seeking to offer a still reliable, but way more streamlined experience for peer-to-peer calls without avatar video feed. Its when OpenAI Realtime API (beta) offers an interesting opportunity.

Note Web development works toward enabling this flow (one of Note Web versions following 11.41):

  1. navigate to NW CAIP Agent Integration web note, that defines your particular NW CAIP experience, eg. for MS Teams calls. It should be connected to knowledge model (i.e. CAIP Agent Setup web note), utilizing OpenAI model, eg. GPT-4o.
  2. in content panel, "Integration Settings" in combo "Prompt detection (audio only)" select option "Voice Activity Detection" (do not use keywords). Keep MS Teams user name/password and other settings as is. Check that option "Chat Mode" is at "Audio", not "Video".
  3. change to MS Teams, find and call MS Teams contact mentioned in previous point
  4. You're all set to speak RAG requests against your knowledge model, issue Note Web PaaS DSL Service commands (capture solution requirements - generate blueprint - build and deploy solution suggestion to AWS or Azure) or send requests to underlying OpenAI model, hear and see NW CAIP Agent responses in chat.

Don't worry about interrupting NW CAIP Agent responses, when needed. Properly identifying request type and extracting function call parameters is way more challenging, than in keywords-based approach, but benefits seem worth the effort.

Drop an email to Note in Web, Inc. if you already have a case for Note Web CAIP Agent streamlined audio experience or would like to find out more!

Note Web DSL targets multi-cloud solutions by adding limited Azure support

How long will it take you to migrate IaC code for AWS EKS cluster with EFS volumes for 12 services (by Ansible) to Azure Kubernetes Services with Azure Files (by Terraform)?

Stay tuned... Details will follow soon.

In the meantime, let's wonder how many errors are to expect on initial "terraform plan; terraform apply" of so migrated code, be it handwritten or emitted by some LLM.

GitHub repository with TypeScript/Java/Python code by Note Web PaaS DSL Service

Any code that NoteInWeb.com generates for your account is your property. It is a non-binding solution suggestion for Note Web DSL blueprint you or Note Web CAIP Agent on your behalf, in chat or through its avatar supply as input.

If you're curious about examples of Note Web PaaS DSL Service generated code, check out https://github.com/denyshavrylov/noteweb-dsl-code-portfolio

This repository purpose is to back each screencast on Note Web channel. There are only a few samples now, but screencast-examples coverage is growing. Also, newer versions of Note Web PaaS DSL Service generate cleaner code, so corresponding branches of this github.com repo are being updated accordingly.

Why is Note Web CAIP Agent Avatar rendered by Unreal Engine Metahuman, while plenty of other avatar services (including GPT-4o/Synthesia on demo video) render photo-realistic?

Delivery pipeline for May 2024 is fully packed on one side. On the other, April and May 2024 are very busy in my other professional ventures. So development capacity for Note Web is yet scarcer than it was before. Still, I work towards providing a Note Web How-to screen-cast that would answer the title question later in 2024 (originally June 2024, then summer 2024, then 2024Q3 - even recent coding LLM advances don't make up for lack of funds in product roadmap, since alluded feature should be reliably accessible to all NoteInWeb.com users to appear in a Note Web How-to screen cast).

NoteInWeb.com cloud solution development approach in a few How-to's

 

 

Development teams can use Note Web to generate boilerplate CRUD code (in Java/Python/TypeScript/Ansible) per standards they define. They can also package their unique expertise as higher order patterns, to be automatically promoted by GPT in its implementation suggestions.

As you can see, the Note Web approach is quite different to that of DevIn or AutoDev. Its goal is not ambitious, just deliver prompt answers and cloud solution suggestions in the virtual context you are in (call, chat, apps), based on your Note Web content and potential of your AWS account.

Can Note Web CAIP Agent benefit from DSPy?

LangChain provides a convenient framework for integrating LLM and Retriever to produce Retrieval-Augmented-Generation. It also automates merging user prompt, problem setting and data retrieved from vector database, that matches combined prompt. There are frameworks and approaches to achieve the same, possibly reducing number of LLM invocations.

DSPy leaves it to developers to decompose their LLM task into modules, define module signatures, come up with at least a dozen of examples for trainings and define metrics to use for optimizing each module. DSPy stands for Declarative Self-improving Language Programs(in python). Note Web CAIP Agent might benefit from DSPy as number of supported AWS/Azure services and higher level patterns grows. Automated prompt tuning would help to turn adding such support for new AWS/Azure services and higher level patterns into largely automated routine.

Overcoming challenges of distilling requirements from discussion transcript and multiple documents

As you can see in previous "How-to" screencasts, Note Web CAIP Agent handles fine demo cases in chat room and voice call scenarios.

128K input tokens of GPT-4 is quite a bulk of text, but the 4096 tokens output is often not enough to document a simple case of CRUD cloud solution for a few entities. However, a group of specialists can discuss so many details in an hour, usually pivoting around a slide deck or wiki page or a few of each, that relevant summary just won't fit 4k tokens even nearly. Needless to mention that RAG can pull in pages of data to augment LLM input yet further.

Note Web CAIP Agent currently can assist you in Amazon Chime chat rooms and voice calls, by summarizing conversation to Problem-Domain-Solution web notes, generating Note Web DSL code from plain text requirements, formulating responses to prompts based on Note Web knowledge models sourcing from files, etc. It can also deploy your Note Web DSL code to your AWS account, straight from chat room or a call. What if you want more control over how your IP is processed?

Stay tuned to see how NoteInWeb.com employs an open source LLM together with Streaming-LLM to put distilling requirements to Note Web DSL code in your full control (your AWS account). Obviously, control over attention sinks won't increase the LLM's context window. But NoteInWeb.com aims to deliver comparable results. Probably after some interleaving with more development on Note Web PaaS DSL stream...

Who's perfect?! So are some NW DSL generated deployment runs, at least for now... If deploy fails, your LLM - to the rescue!

That's another exciting work in progress item, that I just could not hold to myself until a proper feature release (and a corresponding How-to screencast) reach public domain.

Note In Web, Inc.'s development prioritizes hardening actual NW DSL handling to detect naming clashes, resources validation and other issues early, before you hit the deploy button. However, there are plenty of possibilities for how deploy can go wrong for reasons outside of Note Web control. After all, its user's AWS account, credentials, policies and existing infrastructure that Note Web PaaS DSL Service deploys against. You do get the deployment scripts and can play with them however you like. Nevertheless, what if you just need to get your cloud solution to work? While self-healing Note Web deployments still require a lot of research work, NoteInWeb.com would soon offer suggestions for remediation in failing NW DSL code, based on deployment log.

Note Web PaaS DSL Service gains support for TypeScript/NodeJS CRUD container micro-services

As mentioned in few 2023 blog posts, Note Web PaaS DSL Service roadmap includes growing support for the most popular backend development languages and technologies (most noticeable long-term honey pots, in a good sense, being .NET/Azure)

However, speaking of now and considering most established stacks in AWS, there is an obvious gap in NW PaaS DSL Service coverage - TypeScript/NodeJS. So this small article was updated to point to another Note Web "How-to" screencast just about that. It shows how to include a TypeScript/NodeJS CRUD microservice into your AWS cloud solution.

Looking at AI blogs and videos, seems anybody can do Retrieval Augmented Generation with LLMs nowadays. How about creating Problem-Domain-Solution web note straight from your AWS Chime chat room?

This screencast would walk you through the steps required to setup AWS Chime Enterprise account with Okta authentication, register NW CAIP Agent chat bot and use it from your AWS Chime chat rooms.

Stay tuned for a subsequent How-to on actually using the so setup Note Web CAIP Agent to work with cloud solution requirements and runnable implementation suggestions!

... just copy paste the most recent (and relevant, if you prefer) chat room messages to get those summarized as cloud solution requirements. Mention the text to Note Web CAIP Agent chat bot. Voila!

Review the requirements summary in AWS Chime Application UI in chat bot's response or jump back to NoteInWeb.com to access the just generated Problem-Domain-Solution web note! You're all set to generate NW DSL code deployable as Java/Python/Typescript/Ansible source and/or packages/containers!

Deploying from AWS Chime chat room is also possible, just mention it to NW CAIP chat bot.

Safe use of your LLM, VDB and Cloud Account API keys with NoteInWeb.com

NoteInWeb.com empowers you by suggesting a decomposition of your requirements into CRUD microservices with front-ends and storage, generating source code for suggested microservices, storing it in your Git repositories along with deployment Ansible scripts, building, containerizing and deploying them to your Cloud Account.

It is up to you to register for the following services and supply corresponding API keys in your NoteInWeb.com tags:

  • Cloud Account - AWS (incl. free tier)
  • LLM - ChatGPT
  • Vector Database - Pinecone

Until Note In Web, Inc.'s technical operations become SOC2 certified, recommendation stands to generate and dispose of API keys on case-by-case basis. This screencast explains just that. How to generate API keys in these services, how to setup Problem-Domain-Solution and NW Context tags with API keys in NoteInWeb.com UI and how to dispose of API keys, once you don't need further deployable/runnable code suggestions for the current case. This way you don't need to concern yourself about somebody gaining access to your cloud, LLM or VDB account through your NoteInWeb.com account.

NW DSL code generates Angular frontend to S3 bucket backed by authenticating API Gateway, no CDN needed. Less is more, in this case!

Of course, CloudFront brings content closer to users. That matters for Single Page Applications, that Note Web generates out of NW DSL code as well.

However, what if you're still early in development cycle? Manual changes in infrastructure or frontend code can introduce errors. Having another processing layer in CDN, can complicate tracing such issues. Ever wondered, what's use of keeping the long track of each time your CloudFront distribution cache got dumped? There are better things to think about...

Don't use CDN if you don't need it. Drop "cdn" statement in your NW DSL code and Note Web would do proper wiring, including setting CORS policies on API gateway and setting proper access policy for making your S3 bucket public. So that you could access your SPA directly from your S3 bucket sourced from the just deployed AWS API Gateway protected by AWS Cognito user pool authenticator.

Will NW DSL code ever generate a Radius/Dapr solution and deploy to my AWS/Azure account? ... Strong maybe!

Focus of NoteInWeb.com is on personal content management and broader, improved utilization of your public cloud accounts, possibly before you fully onboard all of the needed cloud development expertise. That's why we let you bring your own LLM* and VDB** accounts to generate non-binding Note Web DSL code suggestions and deploy those to your AWS account. Assuming no responsibility for the accuracy of the suggestion, NoteInWeb.com exposes what kind of tech and code could achieve your requirements, while letting you gradually refine the requirements themselves and generated Note Web DSL code. NoteInWeb.com also keeps you in charge of your LLM, VDB and cloud infrastructure costs. There are no hidden premiums each time you generate Java/Python/TypeScript/Ansible for your micro-services and infrastructure. Part of the puzzle is to make understanding generated code easy for the broadest possible developer audience, that's why the guideline of using SDK-level constructs and only well known and proven Open Source libraries.

This separation of concerns might change as company grows in terms of funding, retained user base or revenue. radapp.io and dapr.io tech stacks bring a great selection of higher level patterns, some of which have been mentioned in previous NoteInWeb.com blog posts. However, they come with some learning curve, at minimum:

  • Bicep - which serves purpose similar to part of Note Web DSL for defining cloud resources. Though its syntax resembles Terraform's HCL, there are peculiarities dictated by use.
  • Dapr - building blocks, sidecar pattern, that does all the magic implementing service invocations, state management, pub/sub, bindings, actors, secrets management, workflow and Dapr's approach to configuration, resiliency, workflow and configuration
  • Azure Resource Manager approach to cloud resources control plane (at least for Radius UCP - Universal Control-Plane)

So, NoteInWeb.com can simplify further the leap to using radapp.io/dapr.io tech stacks at some point by making a "cloud"-statement level deployer type "Radius" (next to the currently default "Ansible"). That would also define the code generation of nested micro-services.

Current planning is to approach the matter of higher-level application patterns, possibly via radapp.io and dapr.io tech stack after:

  • publishing a walk though for building SQL and NoSQL microservices with front-end for CRUD and advanced search capabilities over multiple entities. Obviously, with the previously shown authenticating at API gateway for microservices generated code base in Java, Python, TypeScript, deployed to AWS ECS/EKS/Lambda.
  • Note Web chat agent in a well known public chat service
  • dedicated developer and production accounts for improved cloud developer services utilization
  • micro-service code generation for .NET SDK
  • asynchronous micro-service invocations with messaging
  • Note Web DSL deployment to MS Azure
If there is demand from Note In Web, Inc.'s paying customer base, we'll revisit the matter in the title sooner.

How to: secure your AWS ECS/EKS/Lambda invocations behind an AWS API Gateway

What's use of defining your own microservices for Create-Read-Update-Delete applications on multiple entities, if you can't control who can see or change your data? At last this concern, no longer applies to Note Web DSL, as Note Web v.9.40 DSL supports "auth":

  • as standalone keyword - to define AWS Cognito user pools, if deploying to an AWS cloud account
  • as clause for "api gateway" statement to reference particular authentication/authorization configuration

Note Web DSL skyrockets you to a Spring Boot 3.1 microservice on AWS EKS cluster sourcing in RDS MySQL - in 11 LOCs!

What if you don't know yet, if you want your cloud solution to run on AWS EKS cluster backed by Fargate or EC2 nodes? What if you just don't care now, if your data is stored in MySQL or Postgres? But you do know how your data, your forms look like. Then NoteInWeb.com can help! Formulate your requirements as plain text, put in your OpenAI API key (don't forget to remove once done!) and take a look at LLM's suggested Note Web DSL code!

So far, NoteInWeb, Inc. has shown how to generate AWS ECS containers, AWS Lambdas in Python or Java. You're more used to Kubernetes? You've got it! Take a look at this screencast of defining a simple Spring Boot 3.1 Java 17 REST API microservice and deploying that to a just baked AWS EKS cluster.

Note Web DSL is polyglot indeed - generate Python microservices to store data in AWS DynamoDB and index it in AWS OpenSearch

This video focuses on code of generated Python microservice, its configuration for DynamoDB tables and OpenSearch cluster, as well as support for logging, metrics and tracing with X-Ray. AWS OpenSearch cluster used in the demo, was setup by Note Web DSL as well. Actual deployment of AWS OpenSearch cluster is in scope for one of the next videos, to cover setup of authentication for accessing OpenSearch Dashboards, logs shipping from Note Web DSL generated CRUD microservices.
