海外TECH	DEV Community	Experiments && Progress	https://dev.to/nessakodo/experiments-progress-4i6g	Experiments amp amp Progress ContextWithin the scope of this post I am going to delve into some of my understandings in my process of experimenting with the idea of coded music synthesizers I have created a relatively simple audio synthesizer using the Web Audio API and in future posts will deploy my synth as I enhance its interface and functions To get an idea of what I will be discussing here is what the synth I ve coded so far looks like ObjectiveMy primary objective in exploring this project is to utilize the knowledge I ve gathered with HTML CSS and JavaScript to build a functional synthesizer and furthermore determine what possible parameters and displays I can add to it to create an epic tool for creating algorithmic sound This synthesizer uses an oscillator as the source of its sound which I will briefly touch on in my thoughts below InspirationMuch of my inspiration stems from the live coding synthesizer Sonic Pi which has been created by the wonderful Sam Aaron This program is free for anyone to use and is a Ruby based program in which you can build functions to create sounds and manipulate them in front of live audiences The photo below is a photo of the program and a bit of code I ve put into it to create a basic techno beat IntentionAs I continue to work on this project it will evolve in the way it works and functions as my primarily goal is to integrate a container for code to generate and display as some of the parameters are adjusted within the synth I really appreciate what Sonic Pi has to offer its users and really just want to bring more focus to the algoraving scene This post serves to mainly delve into some of the code I created with my novice understanding of JavaScript and I hope as I continue to work on this and other related projects to display the skills I am harnessing as I hopefully become a better coder The basic framework for creating a modular synth should involve a master volume control and I established this with some simple variables const masterVolume context createGain masterVolume connect context destination and an oscillator as the sound source Though I am only going to tap on the topic of what an oscillator is for the sake of simplicity as I am not discussing my assignment of notes in this post I will include the general definition of what an oscillator is An electronic oscillator is an electronic circuit that produces a periodic oscillating electronic signal often a sine wave or a square wave or a triangle wave To add an oscillator to the sound source I created this variable and also connected it to the volume variable in the code above const oscillator context createOscillator oscillator frequency setValueAtTime oscillator connect masterVolume ASDRIn sound and music an envelope describes how a sound changes over time and is essentially an amplitude effect typically made up of values A ttack time D ecay time S ustain level and R elease time or ADSR These are the four main controls of an envelope Envelopes are what make a sound short and punchy and also what enables you to fade in and fade out a sound Here is a visual that might simplify this context Within my code I used JavaScript to create this for the synthesizer to call from Web Audio API doesn t have an envelope built in it is possible to simulate the same effect using gain nodes Before I discuss how the gain nodes are implemented here is the code I used to set initial parameters for the envelope Envelopelet attackTime let sustainLevel let releaseTime let noteLength const attackControl document querySelector attack control const releaseControl document querySelector release control const noteLengthControl document querySelector note length control Within the synthesizer I ve coded I ve included three parameters that a user to adjust the range of the Attack Release and Note Length The event listeners below enables the levels that a user chooses to be registered as values that greatly change the dynamic of the sound chosen and this leads me into my next point attackControl addEventListener input function attackTime Number this value releaseControl addEventListener input function releaseTime Number this value noteLengthControl addEventListener input function noteLength Number this value ConclusionIt might have made sense for me to write this post on the way the sounds were implemented for the synthesizer to play but I think that would be more appropriate for a more in depth post lightly tapping into music theory and some of the ways Sonic Pi also generates notes from numbers I am only a few weeks into my journey with JavaScript and am looking forward to better understanding it through creating and contributing towards projects within my coding school curriculum as well as personal projects I find myself working on incessantly in my free time If you re interested in exploring the Web Audio API for yourself you can explore some documentation with the link below Thanks for reading	2022-08-25 16:47:00

海外TECH	DEV Community	Open Source Single Pane of Glass Monitoring | SigNoz	https://dev.to/signoz/open-source-single-pane-of-glass-monitoring-signoz-2p6i	Open Source Single Pane of Glass Monitoring SigNozSingle pane of glass monitoring is a term used to denote monitoring applications with a single tool that provides a comprehensive set of dashboards for the entire software system of an organization Managing multiple monitoring tools for different aspects of the IT system becomes too cumbersome And that s how the concept of a single pane of glass monitoring evolved Most modern applications are now built using distributed software systems Applications use distributed application architectures like microservices and serverless to serve user demands at a global scale It gets deployed using container orchestration tools like Kubernetes on distributed infrastructure that might be using a hybrid cloud environment Cloud computing and containerization have brought many benefits like speed to market and on demand scaling But it has also increased operational complexity Moreover users expect digital applications to meet their needs in seconds Any latency is missed business opportunity To address these issues engineering teams use monitoring tools to keep a tab on the performance of their software systems For each component of a software system there can be a standalone monitoring tool But it is often challenging for SREs or DevOps engineers to shift between different tools while debugging an issue that needs to be critically solved In this article we will introduce an open source APM tool SigNoz that can be used as a single pane of glass monitoring for your application But first let s learn a bit more about single pane of glass monitoring What is Single Pane of Glass Monitoring Monitoring tools are not of much help in silos for modern distributed software systems You can have application logs and metrics from a single host but the issue can be from a downstream service Correlating events is key to debugging issues quickly Having different tools for different monitoring signals like logs metrics and traces is also challenging You can have one solution for log management and another one for metrics monitoring But if you re experiencing a metrics spike at a certain timestamp you will have to jump between different tools for investigating the event with logs Moreover having multiple monitoring tools slows down engineering teams It is difficult to onboard newer members and often there is a dependency on a few members of the team A tool that provides a single pane of glass to cover all aspects of software systems monitoring is more efficient for debugging applications For cloud native applications a single pane of glass monitoring can enable engineering teams to act fast while serving as a knowledge base for new team members One concern that organizations have while selecting a single monitoring tool is that of creating vendor lock in Open source tools provide a way out In fact OpenTelemetry an open source project that aims to standardize the way telemetry data is generated is solving this particular problem Challenges with Open Source Monitoring ToolsThere are popular open source monitoring tools out there For example we have Prometheus for metrics monitoringJaeger for distributed tracingWhile these tools are great at their specific use cases they do not provide a single pane of glass monitoring experience Moreover the user experience of most open source tools does not match up to their SaaS counterparts As monitoring is a critical part of the DevOps culture organizations need tools that work out of the box And that s why we built SigNoz an open source APM built on OpenTelemetry to provide a single pane of glass monitoring experience An open source APM for Single Pane of Glass MonitoringSigNoz is a full stack open source APM Using SigNoz you can set up a single pane of glass monitoring SigNoz is built to support OpenTelemetry natively OpenTelemetry is an open source project under Cloud Native Computing Foundation that is very suited to instrument cloud native applications for telemetry data OpenTelemetry provides freedom to choose any backend analysis tool freeing you from any vendor lock in SigNoz provides both metrics monitoring and distributed tracing You can also correlate metrics and traces easily with a single click You can also create custom dashboards for monitoring your infrastructure Let s see how SigNoz fits the case for a single pane of glass monitoring with its features Metrics MonitoringSigNoz provides out of box charts and visualization for popular RED requests errors and duration metrics You can also track the top endpoints of your services under a single view Monitor important application metrics and the top endpoints of your service under a single view Distributed TracingDistributed tracing is an important technology aimed at solving performance issues in distributed systems like applications based on microservices architecture SigNoz provides the popular Flamegraph and Gantt chart view that breaks down a user request into all its components as it travels across services and protocols Distributed Tracing can help you visualize your user requests as it travels across multiple services and endpointsSigNoz also lets you run aggregates on trace data Running aggregates on tracing data enables you to create service centric views providing insights to debug applications at the service level It also makes sense for engineering teams as they own specific microservices Running aggregates on your tracing data enables you to create service centric views Log ManagementLogs are part of every developer s workflow and gives the most granular information to debug applications quickly Logs metrics and traces are often touted as three pillars of observability But at its core observability is about solving application issues fast And rather than three pillars logs metrics and traces can act as a single mesh that when correlated intelligently can help developers solve application issues quickly SigNoz also provides log management with advanced features like log query builder search across multiple fields structured table view JSON view etc Log management in SigNoz Infrastructure MonitoringOpenTelemetry provides receivers for receiving metrics from metrics exporters of a lot of common technologies Using these receivers you can build custom dashboards for your infrastructure with SigNoz Using OpenTelemetry receivers you can create custom dashboards with SigNoz For example this is a custom dashboard for Kubernetes host metrics monitoring Exceptions amp ErrorsSigNoz can also help you monitor exceptions in your application code You can monitor popular exceptions like SSLError  ZeroDivisionError  MaxRetryError etc occurring in your application code in one place Monitor all your exceptions in one place with SigNozYou can also dig deeper into the exceptions with its stacktrace Dig Deeper into your exceptions with stacktrace AlertsYou can also set alerts on critical metrics to stay on top of your performance issues Set alerts on critical metrics and get notified on a channel of your choice Getting started with Single Pane of Glass MonitoringGetting started with SigNoz is easy It is easy to get started with SigNoz It can be installed on macOS or Linux computers in just three steps by using a simple installation script The install script automatically installs Docker Engine on Linux However you must manually install Docker Engine on macOS before running the install script git clone b main https github com SigNoz signoz gitcd signoz deploy install shWhen you are done installing SigNoz you can access the UI
