Eillie Anzilotti Public Affairs Specialist at Tableau Hannah Kuffner September 17, 2020 - 4:14pm September 17, 2020 Hard as it is to grapple with the many far-reaching impacts of COVID-19 on our culture, it's even harder to imagine how we would have coped with the same situation even a few decades ago. If the pandemic had hit in 2000 instead of 2020, where would we be? The virtual meetings we conduct for our daily work wouldn't be live on video with document sharing; at best, we'd be on conference calls and sending artifacts by fax. Our safety updates about the virus wouldn't arrive via social media; we'd mostly rely on word of mouth, the daily papers, and the evening news. Likewise, schools would have been in even graver danger of being left behind by COVID-19 than they are right now. The virus has made traditional day-to-day K-12 education all but impossible for the moment, and schools are working with the latest technology to serve their needs in the best ways possible. So what does that look like? How are schools meeting the need for solutions that address the breadth AND depth of the problem? How are they coordinating resources across disconnected, socioeconomically diverse student populations, and meeting the needs of all involved? This blog takes a look at two stakeholder groups: students and their families, and teachers and administrators. In each case, we'll see examples of how people are using data to overcome barriers imposed by the pandemic. Gathering data from students and families For most school districts, the first step in providing an alternate system of instruction was to assess what students wanted and needed in order to participate. They distributed surveys to households, both on paper and over the phone and web, to find out each student's readiness for online remote learning. Did they have a laptop or other connected device for attending classes? Did they need a Wi-fi hotspot in order to access the internet? Once online, could they successfully connect to the district's learning systems? In addition to technological readiness, surveys were also useful for tracking students' engagement. "We wanted to know how students were feeling about distance learning," said Hope Langston, director of assessment services for the Northfield Public School District in Minnesota. Survey responses indicated the level of difficulty students have adjusting to the changes, helping identify areas that needed the most urgent attention. Northfield continues to offer follow-up surveys that help measure their progress in addressing these issues over time. Equal Opportunity Schools (EOS), a Seattle-based nonprofit dedicated to improving access for students of color and low-income students, has conducted research throughout the pandemic that assesses remote learning by aggregating various factors of student sentiment, including teacher and principal evaluation, barriers to motivation, and "belonging" as it pertains to their identity, culture, and classroom experience. EOS uses Tableau to relate these factors to one another and gain insights into possible paths for achieving a more comprehensive learning experience for all students. Equal Opportunity Schools student experience dashboard (EOS) But school isn't entirely about teaching and learning. Districts have resources that help make sure students are healthy and safe, and deploying those resources during COVID-19 also requires a data-driven strategy. The El Paso Independent School District input survey data into Tableau visualizations and used them for planning nutritional and medical interventions where they were needed, including conducting telehealth sessions between school nurses and students who fell ill. If a household couldn't be reached for survey or classroom participation, truancy officers investigated to check on the wellbeing of students in their homes. As a district whose majority population is economically disadvantaged, and where one-third of students has limited English proficiency, these interventions were especially important for ensuring effective, equitable outreach. Student response dashboard (El Paso Independent School District) Similarly, Northfield used Tableau to visualize survey responses and other data related to their holistic pandemic response, with a heightened focus on achieving equity for underserved areas of the district's community, one-quarter of whom qualify for free and reduced lunch. Using a need-based "heat map" visualization as a daily tracker, Northfield set up food distribution centers in strategic locations and tracked the number of meals delivered per day at each site. Langston and her team also used the data to mobilize local volunteers to help families with language and socioeconomic challenges navigate connectivity. Meal distribution counts by location (Northfield Healthy Community Initiative) Throughout these efforts, the availability and visibility of survey responses and other data has been key to coordinating an effective response. "Our dashboards help us meet a need in our community, by getting us the information we need as clearly and as quickly as possible," said Langston. "We couldn't have done this if we didn't have an accurate picture of what the need is." Empowering teachers and administrators Teacher readiness—both practical and emotional—is another important factor in achieving effective remote learning operations, and many districts are using a similar survey-based approach to stay connected with educator sentiment. School administrators rely on this information to make sure teachers are getting the resources and support they need, as well as to work with teachers on tracking student engagement and taking action where needed to help their situation improve. In El Paso, Tableau dashboards track data from the district's remote learning platform and student information system to identify gaps in learning and take immediate action to address them. Viewing data at the district and school levels, and then filtering it down to specific populations or individual students, make it easy to quickly identify students at risk and report each case to the relevant principal or teacher. The visualizations are used to lead weekly meetings among school principals and assign school-specific tasks. El Paso Schoolology participation rates (El Paso Independent School District) "Having the dashboards, and being able to quickly export customized reports, meant we could readily engage school administrators," said Steve Clay, Executive Director of Analytics, Strategy, Assessment, and public education information management systems (PEIMS) for El Paso ISD. "As soon as we noticed problematic numbers, we could hand them a list of students and say: Here are the ones who aren't engaging—what's your plan, what haven't you tried yet, and how can we get you some help?" El Paso also used analytics and reporting to track compliance with new participation-based grading systems, which most teachers had never used before COVID-19. When teachers weren't trained or reminded to use the new system, the grades they reported in the remote learning platform didn't match the new guidelines, potentially confounding the ability to measure student progress. By visualizing the data and seeing the discrepancies, administrators could contact and coach the affected teachers and help bring the invalid grades to a point of fidelity with other measurements in the system. Preparing for the immediate and long-term future As schools continue to evolve their policies and practices, both during and after COVID-19, data will play a key role. Districts that lead the way with data-focused innovations are already finding success in adopting new policies that their states set forth. El Paso's approach to remote learning helped it comply with new standards for student engagement imposed by the Texas Education Authority (TEA) and could readily report its progress to TEA using the codes visible in Tableau. The better equipped a district is to tackle problems efficiently and at a granular level, the more capably they can face down unknown challenges in the future.

Part of the new Angular rendering engine, Ivy, includes a new approach to localizing applications — specifically extracting and translating text. This article explains the benefits and some of the implementation of this new approach. Prior to Ivy, the only way to add localizable messages to an Angular application was to mark them in component templates using the i18n attribute: <div i18n>Hello, World!</div> The Angular compiler would replace this text when compiling the template with different text if a set of translations was provided in the compiler configuration. The i18n tags are very powerful — they can be used in attributes as well as content; they can include complex nested ICU (International Components for Unicode) expressions; they can have metadata attached to them. See our i18n guide for more information. But there were some shortcomings to this approach. The most significant concern was that translation had to happen during template compilation, which occurs right at the start of the build pipeline. The result of this is that that full build, compilation-bundling-minification-etc, had to happen for each locale that you wanted to support in your application. (build times will vary based on project size) If a single build took 3 minutes, then the total build time to support 9 locales would be 3 mins x 9 locales = 27 mins. Moreover, it was not possible to mark text in application code for translation, only text in component templates. This resulted in awkward workarounds where artificial components were created purely to hold text that would be translated. Finally, it was not possible to load translations at runtime, which meant it was not possible for applications to be provided to an end-user who might want to provide translations of their own, without having to build the application themselves. The new localization approach is based around the concept of tagging strings in code with a template literal tag handler called $localize. The idea is that strings that need to be translated are “marked” using this tag: const message = $localize `Hello, World!`; This $localize identifier can be a real function that can do the translation at runtime, in the browser. But, significantly, it is also a global identifier that survives minification. This means it can act simply as a marker in the code that a static post-processing tool can use to replace the original text with translated text before the code is deployed. For example, the following code: warning = $localize `${this.process} is not right`; could be replace with: warning = "" + this.process + ", ce n'est pas bon."; The result is that all references to $localize are removed, and there is zero runtime cost to rendering the translated text. The Angular template compiler, for Ivy, has been redesigned to generate $localize tagged strings rather than doing the translation itself. For example the following template: <h1 i18n>Hello, World!</h1> would be compiled to something like: ɵɵelementStart(0, "h1"); // <h1>ɵɵi18n(1, $localize`Hello, World!`); // Hello, World!ɵɵelementEnd(); // </h1> This means that after the Angular compiler has completed its work all the template text marked with i18n attributes have been converted to $localize tagged strings which can be processed just like any other tagged string. Notice also that the $localize tagged strings can occur in any code (user code or generated from templates in both applications or libraries) and are not affected by minification, so while the post-processing tool might receive code that looks like this ...var El,kl=n("Hfs6"),Sl=n.n(kl);El=$localize`Hello, World!`;let Cl=(()=>{class e{constructor(e)... it is still able to identify and translate the tagged message. The result is that we can reorder the build pipeline to do translation at the very end of the process, resulting in a considerable build time improvement. (build times will vary based on project size) Here you can see that the build time is still 3 minutes, but since the translation is done as a post-processing step, we only incur that build cost once. Also the post-processing of the translations is very fast since the tool only has to parse the code for $localize tagged strings. In this case around 5 seconds. The result is that the total build time for 9 locales is now 3 minutes + ( 9 x 5 seconds) = 3 minutes 45 seconds. Compared to 27 minutes for the pre-Ivy translated builds. Similar improvements have been seen in real life by teams already using this approach: The post-processing of translations is already built into the Angular CLI and if you have configured your projects according to our i18n guide you should already be benefitting from these faster build times. Currently the use of $localize in application code is not yet publicly supported or documented. We will be working on making this fully supported in the coming months. It requires new message extraction tooling — the current (pre-Ivy) message extractor does not find $localize text in application code. This is being integrated into the CLI now and should be released as part of 10.1.0. We are also looking into how we can better support translations in 3rd party libraries using this new approach. Since this would affect the Angular Package Format (APF) we expect to run a Request for Comment (RFC) before implementing that. In the meantime, enjoy the improved build times and keep an eye out for full support of application level localization of text. Angular localization with Ivy was originally published in Angular Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

Photo by Emma Twersky TL;DR Our interns were phenomenal! Read on to find out why. We’ve just wrapped up our latest intern cohort on the Angular team. Please believe me when I tell you that there are some outstanding folks out there and we were lucky enough to get to work with a few of them. Because of the ongoing pandemic Google internships were fully remote. We’re fortunate to have had some really special folks because they were outstanding. Let’s take a look at the great work developed during this cohort on the Angular Team! Better Paths for Learners One of things we’re focused on with the team is making sure that the Angular learning journey works for experienced developers and new developers. Our wonderful intern on the DevRel team, Gloria, took this mission to heart. Gloria Nduka zeroed in on the friction of the learning path for new developers. She used those insights to not only help the team but also to create an interactive tutorial focused on helping developers new to Angular. The tutorial puts the output, code, and next steps in the same window allowing learners to reduce context switching. Gloria’s second project focused on reaching out to and partnering with computer science programs to expose more students to the platform. She was able to make some meaningful connections and we are excited to continue to this initiative. Seeing Opportunities in the CDK The Angular CDK is a wonderful resource aimed at abstracting common application behaviors and interactions. Andy Chrzaszcz saw an opportunity to add new functionality to menus and improve accessibility. He added some great new directives to the CDK that give developers an expressive way to build powerful menus for Angular apps! The foundation set via his contributions will give developers the ability to build all types of menus with advanced interactions like sub-menus, intelligent menu closing and more. Developers will be able to craft menus that meet the application’s needs. A Combination of Great Things Popping Up Presenting lists of data for user’s to select from is standard fare in web development. But how can the Angular CDK help with that? Niels Rasmussen gives us that answer with his project aimed at creating directives that provide a foundation for implementing complex combobox UI components. Because the goal of the Angular CDK is to provide common behaviors, Niels’s solution follows suit for the list box and combo box gives developers the freedom to customize the presentation of the UI to their specific use cases. This brings much welcomed flexibility into the fold. Thanks for Sharing Your Gifts With Us Finally, we want to send an enthusiastic thank you and good luck to all of our interns as they finish up their undergraduate programs. We’ve seen the future in you and things are looking incredibly bright. If you’d like to be an intern here at Google, we invite you to apply. The world needs your gifts and talents. These projects will be released in future versions of the platform. Stay tuned for updates.

Did you know Ionic and Angular power roughly 10% of the apps on iOS and almost 20% of apps on Android? Let’s repeat that: Angular powers a significant chunk of apps in the app stores. Why is it helpful to know this? Well, if you were on the fence about what technology choice you should make for your next app, it should be reassuring to know that apps powered by web technology are thriving in the app store. Let’s explore how we came to that conclusion and why it matters. First, for a number of reasons, users visit these stores and download apps that help them in their day-to-day lives. Users are searching for ToDo apps (who doesn’t love a good ToDo app), banking apps, work-specific apps and so much more. A good portion of these apps are built using web technologies such as Ionic and Angular. But enough talk, let’s look at some numbers to back this up. The Data If you’ve never heard of Appfigures, it’s an analytics tool that monitors and offers insights on more than 150,000 apps. Appfigures provides some great insight into what kind of tools developers are using to build their apps. Like what’s the latest messaging, mapping, or development SDK? That last one is the most important metric we want to explore. Let’s look at what the top development SDKs are for app development: Data from https://appfigures.com/top-sdks/development/apps Woah, roughly 10% of the apps on iOS and almost 20% of apps on Android use Ionic and Angular. This is huge. The data here is gathered by analyzing the various SDKs used in apps on the app stores. In these charts we see some options that are to be expected like Swift and Kotlin. But Ionic and Angular are still highly present. We could even include Cordova, since many Ionic apps are Cordova-based, and these stats would increase even more. But we’ll keep to the data that we know for sure. Given the number of apps out there, even 10% and 20% are a significant size. If you ignore Appfigures, you can get a sense of how many Ionic/Angular apps are there by just searching for “com.ionicframework”, which is our starting package ID (also, people should really change this). Here’s a link if you’re interested. Why Angular for mobile? Developers are using Ionic and Angular power a good chunk of the app stores. With everything Angular has to offer in terms of developer experience, tooling for fast apps, and its ecosystem of third-party libraries (like Ionic), it’s no wonder developers choose it as their framework of choice. From solo devs, to small shops, to large organizations like the UK’s National Health Service, Boehringer Ingelheim and BlueCross Blue Shield, these organizations have selected Angular and Ionic for their tech stack, and you should feel confident to do so as well. Web vs. App Stores If Ionic and Angular are based on web technologies, why even target the app stores at all? With Progressive Web Apps gaining traction and the web becoming a more capable platform, why not just deploy to the web and skip the app stores? Well it turns out that the app stores provide a lot of value that products need. Features like Push Notifications, File System API, etc are starting to come to the web, but they are still not fully available in every browser. Building a hybrid app with Ionic and Angular can allow developers to use these features and gracefully fallback when these APIs are not available. Discoverability is also another big factor here. While we can search for anything on the web, having users discover your app can be challenging. With the app stores they regularly promote new apps and highly rated apps as well. This can make the difference between a successful product and one that fails. The Best of Both Worlds The web is still an important step to shipping a great app. But when developers want to target different platforms, having the right libraries in place can make all the difference. For instance, if you want to build a fast and performant web app, Angular is an excellent choice and is statistically the choice many developers make. On the other hand, if you want to bring that app experience to a mobile device, with full access to every native feature and offline capabilities, then a hybrid mobile app using Angular plus a mobile SDK like Ionic is the way to go. Either way, your investment in Angular will serve you well. And you’ll be in good company, with millions of devs and nearly a million apps right alongside you. Ionic + Angular: Powering the App store and the web was originally published in Angular Blog on Medium, where people are continuing the conversation by highlighting and responding to this story.

With thanks to the kind folks at Lander Analytics, video from my New York R Conference talk earlier this month is now available to view. The slides are also available for download in PDF format. In my talk, I described how I automated the deployment of a Shiny app using GitHub Actions. If you're new to GitHub Actions, it's pretty simple to set up a continuous deployment process: Define jobs as YAML files in the .github/workflows folder of your GitHub repository Search the GitHub Actions Marketplace for templates of tasks you'd like to perform Push changes to your workflow to trigger Actions according to the rules you specify In my case, I used Actions to create an on-demand cluster of VMs in Azure Machine Learning service, to train R models on the cluster with the azuremlsdk package, to deploy the trained model as an HTTP endpoint in Azure Container Instances, and to update the Shiny app which calls out to that endpoint. In the talk, I demonstrate the process in action (the demo starts at the 14:30 mark in the video below). I used Visual Studio Code to edit the app.R file in repository, and then pushed the changes to GitHub. That immediately triggered the action to deploy the updated file via SSH to the Shiny Server, running in a remote VM. Similarly, changes to the data file or to the R script files implementing the logistic regression model would trigger the model to be retrained in the cluster, and re-deploy the endpoint to deliver new predictions from the updated model. I've provided the complete GitHub repository implementing the app, the models, and the Actions at github.com/revodavid/mlops-r-gha. If you want to try it out yourself, all you need to do is clone the repo, follow the instructions to add secrets to your repository and set up the Shiny VM, and then trigger the Actions to build everything. The repository also includes links to references and other resources, including how to create a free Azure subscription with credits you can use to test everything out. If you have any questions you suggestions, please feel free to add an issue to the repository! GitHub (revodavid): MLOPS with R: An end-to-end process for building machine learning applications

Whenever you have a system that is reliant upon composition, it’s critical that each piece of that system has an interface for accepting data from outside of itself. You can see this clearly illustrated by looking at something you’re already familiar with, functions. function getProfilePic (username) { return 'https://photo.fb.com/' + username } function getProfileLink (username) { return 'https://www.fb.com/' + username } function getAvatarInfo (username) { return { pic: getProfilePic(username), link: getProfileLink(username) } } getAvatarInfo('tylermcginnis') We’ve seen this code before as our very soft introduction to function composition. Without the ability to pass data, in this case username, to each of our of functions, our composition would break down. Similarly, because React relies heavily on composition, there needs to exist a way to pass data into components. This brings us to our next important React concept, props. Props are to components what arguments are to functions. Again, the same intuition you have about functions and passing arguments to functions can be directly applied to components and passing props to components. There are two parts to understanding how props work. First is how to pass data into components, and second is accessing the data once it’s been passed in. Passing data to a component This one should feel natural because you’ve been doing something similar ever since you learned HTML. You pass data to a React component the same way you’d set an attribute on an HTML element. <img src='' /> <Hello name='Tyler' /> In the example above, we’re passing in a name prop to the Hello component. Accessing props Now the next question is, how do you access the props that are being passed to a component? In a class component, you can get access to props from the props key on the component’s instance (this). class Hello extends React.Component { render() { return ( <h1>Hello, {this.props.name}</h1> ) } } Each prop that is passed to a component is added as a key on this.props. If no props are passed to a component, this.props will be an empty object. class Hello extends React.Component { render() { return ( <h1>Hello, {this.props.first} {this.props.last}</h1> ) } } <Hello first='Tyler' last='McGinnis' /> It’s important to note that we’re not limited to what we can pass as props to components. Just like we can pass functions as arguments to other functions, we’re also able to pass components (or really anything we want) as props to other components. <Profile username='tylermcginnis' authed={true} logout={() => handleLogout()} header={<h1>👋</h1>} /> If you pass a prop without a value, that value will be set to true. These are equivalent. <Profile authed={true} /> <Profile authed />
