海外TECH	DEV Community	Passwordless.ID - Screenshots 🖥️	https://dev.to/dagnelies/passwordlessid-screenshots-2g0j	Passwordless ID Screenshots ️Passwordless ID is a free public identity provider allowing users to sign in up in web apps using their fingerprint face recognition or local authentication mechanisms like swipe pattern or PIN code The results are no more passwords a much smoother user experience and vastly improved security It provides two factor authentication using a single touch or a smile in the camera Awesome right Try it now it s a public service free forever no account necessary Since a picture is worth a thousand words here it comes and actually a bunch of them Authentication on various platformsI used my own phone laptop with a German locale sorry guys The cornerstone of this authentication service is to delegate user verification to the local platform You may use your device s fingerprint sensor some swipe pattern windows hello with face recognition or even plain old passwords whatever is configured on your device locally By the way if anybody could provide me a screenshot from a Mac or IPhone that would be great Creating a new userCreating a new user only requires a username An e mail address although useful is entirely optional Why Because there is no need for I forgot my password Upon clicking Create Account you will be prompted for local authentication Once done your account is created That s it What follows is simply defining your profile if you want to Signing inOnce you pick your avatar you must prove it s you by using local authentication Don t worry none of the information like fingerprint or pin codes is ever sent to the server It is used locally to sign a message using asymmetric cryptography and prove you are you OAuth OpenID flowThat is the whole purpose of this service So that any website on the internet can easily ask Who are you Since it is public you can use it out of the box even without account Managing devicesOne of the more unusual aspects of this kind of authentication is that it is more secure by default Only your registered devices can sign in As such it is important to easily add a new device Once you scan the QR code you will be able to register your other device directly And after a while you may end up with several authorized devices If you cannot scan the QR code or open the link in the e mail you can also enter the OTP code manually Recovery optionsNow if you have registered only a single device without email or phone you might be in trouble In that case losing your device would make it impossible to connect to your account anymore That s why the interface emphasizes user guidance It is a new topic for the users too After a classic e mail confirmation it looks already much better Alternatively you could also have just registered another device per QR Code Both are ways to ensure safety E Mail confirmation and recoveryIMHO the screenshots do not really convey the usage and the feeling of this service very well However it might give a slight idea of it I recommend trying out the demo if you are curious or looking at the main site Although it s usable and has the fundamental things working right it is still a bit rough around the edges It still has to be fleshed out regarding certain aspects and needs some polish too But it s working It is in a kind of an early preview That is why feedback is always welcome	2023-02-20 08:45:08

海外TECH	DEV Community	AWS open source newsletter, #145	https://dev.to/aws/aws-open-source-newsletter-145-4ee0	AWS open source newsletter Feb th Instalment Welcome to edition of the AWS open source newsletter I hope some of you were able to catch the new Build on Open Source show we live streamed last Friday You can catch up and replay the session by clicking on this link where we went over a number of projects from this and a few previous newsletters and we had special guest Valter who walked us through his project terraform dev containers During this episode we asked viewers to provide some quick feedback as to let me know what you find most useful from reading this newsletter Please take seconds to let me know by clicking on the Twitter Poll hereIt has been two weeks since the last newsletter so this week we have a bumper edition with plenty of great new open source projects for you to try out We have ses sidecar which provides a way of using IAM Roles with Amazon SES centralized logs a tool to help you replicate your CloudWatch logs ccExplorer a cli tool to show your AWS resource costs boto formatter a neat tool that provides additional output formats for boto redshift migrate db a tool to simplify migrations in Amazon RedShift aws break glass role a nice example of implementing this control in your secure environments dynamic ec budget control a tool to help cost optimisation for HPC workloads visualize iam access analyzer policy validation findings does what it says on the tin amazon kinesis data streams health check a tool that helps you ensure your Amazon Kinesis streams are what you expect and many more Also covered this week are some great open source technologies including Apache Flink Apache Spark Kubernetes Amazon EKS Apache Iceberg Argo Workflows Quarkus OpenSearch PostgreSQL AWS Amplify AWS ParallelCluster AWS SAM AWS CDK Apache Airflow Amazon EMR Redis OCSF HBase Grafana Prometheus Karpenter and more Before you dive into the newsletter check out the following information in how you can possible help with the recent Turkey Syria Earthquake disaster VOLUNTEERS NEEDED Active disaster volunteer opportunitiesTurkey Syria Earthquake Humanitarian Mapping OpportunityHOW YOU CAN HELP Volunteers will use HOT s Map Tasking Manager to trace satellite imagery that helps responders identify priority areas and more efficiently plan aid to people in need HOT runs on AWS and is built on top of OpenStreetMap data OSM is a free editable map of the world created and maintained by volunteers and available for use under an open license Celebrating open source contributorsThe articles and projects shared in this newsletter are only possible thanks to the many contributors in open source I would like to shout out and thank those folks who really do power open source and enable us all to learn and build on top of what they have created So thank you to the following open source heroes Aidan Steel Colin Dugan Syed Rehan Lukonde Mwila Paul Hidalgo Rupal Mahajan Joshua Bright Anirudha Jadhav Joshua Li Sayali Gaikawad Fabio Oliveira Petri Kallberg George Zhao Kalen Zhang Jiseong Kim SungYoul Park Luis Gerardo Baeza SaiKiran Reddy Aenugu Narendra Merla Subhro Bose Eva Fang Ketan Karalkar Andriy Redko Francesco Tisiot and Payal Singh Latest open source projectsThe great thing about open source projects is that you can review the source code If you like the look of these projects make sure you that take a look at the code and if it is useful to you get in touch with the maintainer to provide feedback suggestions or even submit a contribution Toolsses sidecarses sidecar the first of two tools from Aidan Steel This repo contains code that allows you to deploy an SMTP server sidecar to allow AWS SES usage with IAM roles AWS SES has an SMTP interface but it doesn t support IAM roles so this proof of concept helps fix that As Aidan says I m on a personal crusade against IAM users so I made an SMTP server designed to run as a sidecar to your legacy app that speaks SMTP but needs to use IAM role credentials centralized logscentralized logs another tool from Aidan Steel that provides a code less solution to aggregating AWS CloudWatch log subscriptions across multiple AWS accounts and regions It uses Kinesis Firehose for aggregation and forwarding EventBridge for notifications about new log group creation and Step Functions for assuming roles cross account and calling the AWS SDK aws cloudwatch dashboard generator for infrastructure event managementaws cloudwatch dashboard generator for infrastructure event management is a command line tool is to generate a CloudWatch Dashboard which is based on a list of resources you provide and contains predefined useful CloudWatch metrics selected by AWS Support engineers for monitoring AWS resources during special events or IEM AWS Infrastructure Event Management scenarios The tool is quite simple It reads a CSV file to get your resource IDs then output the dashboard JSON to the directory you specified The README provides examples on how to create the CSV input file the supported AWS resource types and more ccExplorerccExplorer Cloud cost explorer is a simple command line tool from Colin Duggan to help you explore the cost of your cloud resources It s built on open source tools like cobra go echarts and go pretty It lets you quickly surface cost and usage metrics associated with your AWS account and visualise them in a human readable format like a table csv file or chart It was created so I could quickly explore and reason about service costs without switching context from the command line It s not designed as a replacement for the official AWS COST Explorer CLI but does provide some nice features for visualisation and sorting I deployed this using the information in the README and it was easy to get started There are also plenty of example recipes to get you going For folk who love living in the terminal this project is a must check out boto formatterboto formatter is decorator that convert standard boto function response returned as python list in flattened JSON or tabular CSV formats for list of supported services and functions You can output the response to print file or send flattened columnar JSON list to another function to continue your process boto formatter simplifies the process and reduce the need of writing custom codebase potentially of s of line of code to lines of code for simple use cases like generating list of lambda functions or list of cloudfront distriubtions with all the attributes that AWS Python SDK provides redshift migrate dbredshift migrate db this tool helps you to migrate a single database within an Amazon Redshift cluster to another cluster via Datasharing Datasharing is a capability within Amazon Redshift where you can share live data with relative security and ease across Amazon Redshift clusters AWS accounts or AWS Regions for read purposes aws break glass roleaws break glass role this repo helps you create a break glass role for emergency use in order to limit production console access Why would you need such a thing I can hear you all thinking my Jedi skills are strong Often when undergoing security reviews for applications in a full CI CD deployment environment it is recommended to restrict console access to the AWS account that hosts the production environment A popular way to implement this recommendation is to remove all production write access completely from user and role policies In these cases it may be necessary to provision a user or role with elevated permissions to be used only in emergency cases This type of role is typically called a Break Glass Role and is usually used in On Call situations or other circumstances when quick mitigating action is needed Read the rest of the README to help you understand more how you can go about implementing this approach in your own environments dynamic ec budget controldynamic ec budget control is a project for those running HPC workloads that will provide you with some more options to help manage costs This solution uses a dynamic EC cores allocation limit for each business unit BU automatically adapted according to a past time frame e g one week spending that can be adapted anytime according to workload spikes or priorities EC cores allocation limit is enforced in the HPC workload scheduler itself with the use of its dynamic resources HPC jobs breaking the limit will be kept in queue pending status until more cores are released by completed older jobs With this approach a related job pending reason is also provided to both business or job owners making them aware of their spending implications visualize iam access analyzer policy validation findingsvisualize iam access analyzer policy validation findings how to create an Amazon QuickSight dashboard to visualise the policy validation findings from AWS Identity and Access Management IAM Access Analyser You can use this dashboard to better understand your policies and how to achieve least privilege by periodically validating your IAM roles against IAM best practices amazon kinesis data streams health checkamazon kinesis data streams health check provides an example approach to demonstrate health checking the Kinesis Data Streams service by producing a tracer message to a health check stream and consuming it to produce a realtime custom metric to CloudWatch The custom metric can in turn be used to setup an Alarm for immediate alerting in case producing and consuming capabilities to the service are impaired Demos Samples Solutions and WorkshopsData Lake for NonprofitsData Lake for Nonprofits is an open source application that helps nonprofit organisations set up a data lake in their AWS account and populate it with the data that they have in the Salesforce Non Profit Success Pack NPSP schema It uses AWS Amplify to provide a nice easy to use front end and you can see what this looks like and dive deeper by reading the post Dive Deeper into Data Lake for Nonprofits a New Open Source Solution from AWS for Salesforce for Nonprofitsspark on aws lambdaspark on aws lambda is a standalone installation of Spark running on AWS Lambda The Spark is packaged in a Docker container and AWS Lambda is used to execute the image along with the PySpark script Currently heavier engines like Amazon EMR AWS Glue or Amazon EMR serverless are required for event driven or streaming smaller files to use Apache Spark When processing smaller files under MB in size per payload these engines incur resource overhead costs and operate more slowly slower than pandas This container based strategy lowers overhead costs associated with spinning up numerous nodes while processing the data on a single node Use Apache Spark on AWS Lambda for event based pipelines with smaller files if you re seeking for a less expensive choice according to customers multi pipeline serverless web application with cdkmulti pipeline serverless web application with cdk This project allows you to build a serverless web application with multiple pipelines managed separately by your infrastructure and development teams By provisioning this project you can see and experience whether a serverless architecture will behave the same as a traditional architecture Detailed and comprehensive README will help you navigate this sample eks container pipeline cdk templateeks container pipeline cdk template is a CDK TypeScript project that

user of the Amazon EKS Workshop then you will be happy to hear that this has been redesigned and relaunched You can still access the old workshop if you want Find out more by reading the announcement Introducing the Amazon EKS WorkshopAWS SDK for Java xAnnounced last week was the AWS Common Runtime CRT HTTP Client in the AWS SDK for Java x With release version of the SDK the AWS CRT HTTP Client can now be used in production environments The AWS CRT HTTP Client is an asynchronous non blocking HTTP client that can be used by AWS service clients to invoke AWS APIs You can use it as an alternative to the default Netty implementation of the SdkAsyncHttpClient interface It offers faster SDK startup time and smaller memory footprint which is especially important with AWS Lambda as well as lower P latency and enhanced connection management Dive deeper by reading the post Announcing availability of the AWS CRT HTTP Client in the AWS SDK for Java xAWS ParallelClusterPrevious versions of AWS ParallelCluster enabled HPC clusters in a single Amazon EC Availability Zone With AWS ParallelCluster you can now create clusters that use multiple Availability Zones in a Region This gives you more options to provision computing capacity for your HPC workloads You can find out more by reading the post Multiple Availability Zones now supported in AWS ParallelCluster MySQLAmazon Relational Database Service Amazon RDS for MySQL now supports MySQL minor versions and We recommend that you upgrade to the latest minor versions to fix known security vulnerabilities in prior versions of MySQL and to benefit from the numerous fixes performance improvements and new functionality added by the MySQL community PostgreSQLPostgreSQL extensions are libraries that supply extra functions operators or data types to the core database engine Amazon Relational Database Service Amazon RDS for PostgreSQL now supports the tcn extension which provides a trigger function that allows you to asynchronously notify listeners of changes to a table tcn or triggered change notification is a function that generates NOTIFY events on changes to data in specified tables This is useful for applications that need to take action on data changes in near real time such as updating displays of information or cached data Another extension that was also added last week was the seg extension which provides the seg data type for representing line segments or floating point intervals The seg extension provides a data type with operators that allow for storing and querying of line segments or intervals with arbitrary variable precision This is useful for applications needing to represent laboratory measurements OpenSearchThe OpenSearch Project announced last week the release of the Reporting CLI making it convenient to generate reports externally without logging in to OpenSearch Dashboards This gives you the flexibility to programmatically generate reports and connect them to your preferred messaging system You can now schedule and transport reports efficiently through email Check out the post What s new OpenSearch Reporting CLI where Rupal Mahajan Joshua Bright Anirudha Jadhav Joshua Li and Sayali Gaikawad dive deeper into this new release Amazon EMRLast week a new capability was announced for Amazon EMR on EKS to increase job execution resiliency Until now users had to build their own custom job execution retry mechanism outside of Amazon EMR on EKS to make sure their Spark jobs keep running in case of failure With this feature users can now save time and keep their business critical and long running streaming workloads running by having Amazon EMR on EKS automatically re submit jobs in case of failure With job retries once you define a retry policy by providing the amount of attempts to limit executions to Amazon EMR on EKS will enforce and monitor this policy during each job execution giving you visibility via the DescribeJobRun API and AWS CloudWatch events of each retry being performed Also announced was an update to Amazon EMR Serverless Previously the largest worker configuration available on EMR Serverless was vCPUs with up to GB memory Today we are excited to announce that EMR Serverless now offers worker configurations of vCPUs with up to GB memory and vCPUs with up to GB memory allowing you to run more compute or memory intensive workloads on EMR Serverless You can read more about this by checking out the blog post Amazon EMR Serverless supports larger worker sizes to run more compute and memory intensive workloadsRedisAmazon ElastiCache for Redis now includes enhanced I O multiplexing which delivers significant improvements to throughput and latency at scale Enhanced I O multiplexing is ideal for throughput bound workloads with multiple client connections and its benefits scale with the level of workload concurrency As an example when using rg xlarge node and running concurrent clients you can achieve up to increased throughput read and write operations per second and up to decreased P latency compared with ElastiCache for Redis For throughput bound workloads with multiple client connections network I O processing can become a limiting factor in the ability to scale Since March ElastiCache for Redis optimizes compute utilization by handling network I O on dedicated threads allowing the Redis engine to focus on processing commands With this launch each dedicated network I O thread pipelines commands from multiple clients into the Redis engine taking advantage of Redis ability to efficiently process commands in batches You can read more about this in the supporting blog post New for Amazon ElastiCache for Redis Get up to better throughput with enhanced I O multiplexingAWS SAMThe AWS Serverless Application Model SAM Command Line Interface CLI announces the launch of sam list command helping developers access information about deployed resources while they are testing their SAM applications The AWS SAM CLI is a developer tool that makes it easier to build test package and deploy serverless applications Customers can now use the SAM CLI to inspect resources that are defined in their SAM application or deployed within a CloudFormation stack including the endpoints methods and stack outputs required to test the deployed application Previously customers had to use AWS Console to retrieve specific values per resource like endpoint URL and use these retrieved values in their preferred testing tool to invoke their application With this launch SAM CLI users can avoid the context switch during testing their applications and retrieve the information they need via sam list command speeding up their iteration cycles This feature is available with SAM CLI version Videos of the weekOpen Sourcery Ep VGV AWS AmplifyIt is always great to see new open source shows on Twitch and You Tube Open Sourcery started off as a show and tell from VGV and

海外TECH	DEV Community	Refactor your CSS NOW!!	https://dev.to/hellonehha/refactor-your-css-now-3oo8	Refactor your CSS NOW Global ResetWhen working with CSS the user agent stylesheet is automatically applied to HTML elements It s crucial to reset this stylesheet before creating your own styles for the project One common practice is to reset the margin and padding values to Why To avoid repetitive line of codes margin padding CSS VariablesMaintaining consistency in your code is crucial especially when it comes to CSS where it s important to maintain consistency in areas such as color font size and spacing One way to ensure consistency is by using variables which can be declared once and reused throughout the code CSS variables not only help maintain consistency but also make it easier to maintain the code over time For example if you need to update a color in your CSS you can do it in one place using CSS variables root primary color h color var primary color box sizingThe box model is a fundamental concept in CSS that involves calculating an element s width and height based on its border and padding If an element has a fixed width or height as well as padding or a border it may result in extra pixels being added to the width or height which can cause bugs in the layout To calculate the width of an element with the box model you would add its width to its border and padding width of element width border paddingLooking at the image above we can see that the width of the div is px However due to the presence of padding and border the actual width of the element has increased to px To prevent this issue from occurring it s recommended to set the box sizing property to border box This ensures that the container s width is not affected by the padding and border and any padding or border added to the element is included within the specified width of the element div width px height px background eee padding px border px solid box sizing border box box sizing box model By setting the box sizing property to border box you can avoid a lot of time and frustration spent trying to fix layout issues such as elements breaking or extra pixels being added to a container with a fixed width This simple technique can save you a lot of time and headaches in the long run is is is a CSS pseudo class function that allows you to test if an element matches a certain selector It returns a boolean value of true or false depending on whether the element matches the specified selector This helps in writing less do more and ease of readability lt input type text gt lt input type email gt input type text input type email section h section h section h instead of the above do this input is type text type email section is h h h font size unitsWhile px is the most commonly used unit in CSS it has its limitations One major issue is that it doesn t adjust based on screen size which can make it difficult to create responsive layouts and maintain the code over time Fortunately there are other units available such as em and rem that can make it easier to create responsive designs and maintain the code When selecting units for your CSS it s important to follow these guidelines Maintain consistency throughout your code Choose units that are responsive to different screen sizes Select units that are easy to change and maintain over time For fonts it s recommended to use rem and for spacing it s best to use em However you should still use px units when necessary based on the requirements of your design has has is a CSS pseudo class selector that matches elements based on whether they contain a specific element or not It allows you to select an element that has another element as a descendant regardless of how deep the descendant is nested For example you could use has to style all div elements that contain an H and H element differently Happy Learning Twitter Linkedin	2023-02-20 08:03:28
