HackerNoon Reporter: Please tell us briefly about your background. I grew up in New Jersey. I went to school at the University of Pennsylvania where I majored in systems engineering and played varsity volleyball. I spent several years working at Lockheed Martin specializing in simulation for the Navy before moving over to Zoomer and later Grubhub where I led decision engineering work for delivery planning and optimization. What's your startup called? And in a sentence or two, what does it do? Our company is called Nextmv. (We pronounce it "next move" but we're not picky about it.) Nextmv’s decision stack helps developers automate and optimize business decisions for routing, scheduling, and other operations. What is the origin story? If you go way back, Nextmv’s story is grounded in systems engineering, optimization research, ballistic missile simulation, and pizza delivery in the time of paper map directions and walkie-talkies. More recently, I spent a few years leading decision engineering at Grubhub with my cofounder Ryan O’Neil, building automation and optimization solutions for food delivery. We saw a chance to better serve developers tackling these challenges and others like scheduling and packing in a new way. And that’s how Nextmv started. Nextmv is delivering the power of decision science to every developer. We believe it’s the missing link between data science and operations. Where data science answers what's going on, the Nextmv Decision Stack tells you what to do about it. What do you love about your team, and why are you the ones to solve this problem? We’re a remote-first company that’s distributed all around the globe. Most of us come from the worlds of optimization, routing and delivery, warehousing robots, search, and software development — all relevant to the problem we’re looking to solve. That said, I love the diversity of backgrounds, experiences, and tremendous thought that goes into everything we do. On a personal level, the team is a remarkable bunch with interesting lives outside of work, good senses of humor, and the Slack emoji/gif force is strong within our crew. If you weren’t building your startup, what would you be doing? If I wasn’t playing in the decision science space, I’d probably be doing a combination of coaching volleyball, traveling (ideally abroad), adventuring with my doggo, and cooking. I can’t really imagine working anywhere else since we started this thing. At the moment, how do you measure success? What are your core metrics? We look at traditional metrics like recurring revenue, customer health scores, and traffic to our online properties. At the next layer down, some of the metrics we look at include the number of daily active customers, API calls our customers make, and the number of decisions (e.g., routes assigned, schedules blocked) made. What’s most exciting about your traction to date? It’s been particularly exciting to see reactions to our content (on our website or HackerNews) and our product from people in the community. You see it in how people comment about how to think about optimization differently, applying it in new ways, learning more about decision science and engineering, or just getting really excited about the ways in which our team is building out and shipping features in our decision stack. What technologies are you currently most excited about, and most worried about? And why? I’m generally excited about all of the movement in the decision science tech space. For a long time, companies only had a few tech options to automate and optimize decisions for their operations. You typically only saw users in more legacy industries (manufacturing, defense, and supply chain) and academia. That’s changed in the last few years. You’re starting to see companies like Amazon, Walmart, Wayfair, Instacart, Grubhub, and others really have a presence at optimization conferences. I worry about the challenge we have ahead of us. Optimization and decision science haven’t always been super accessible. A large part of our work will always be rethinking how we present complex ideas and systems to our users in a clear, concise manner. But you know what they say: "problems worthy of attack prove their worth by fighting back.” What drew you to get published on HackerNoon? What do you like most about our platform? HackerNoon has always been a known resource in my universe of reading materials. It’s certainly taken on new context for me now as a startup founder. I’m super interested in community building, and I think HackerNoon has an interesting place in that realm with the work done to create an accessible space for technologists to swap stories and learn from one another. It’s incredibly powerful and valuable. What advice would you give to the 21-year-old version of yourself? Two things: 1) What got you here doesn’t necessarily get you there. You always need to be growing, changing, and making new decisions based on what’s in front of you. And 2) don’t assume everyone has it all figured out. We’re all doing 1 ^ What is something surprising you've learned this year that your contemporaries would benefit from knowing? You can build a strong team that’s remote from the beginning. Nextmv grew from 2 to 3 employees at the start of the pandemic. We’re now 25+ people. Most folks haven’t met one another. (That will change in the future!) We span several time zones. Making it work takes work, of course, by being smart about meetings, building out really strong asynchronous communications, creating shared experience, not drowning in Slack messages (even if we are heavy Hey Taco users). Don’t forget to vote for Nextmv as ! Startup of the Year in Philadelphia

240 Stories To Learn About Startups Of The Year

Meet the Winners of Startups in North and Central America

For six-months (and counting) COVID-19 has accelerated the need for SMBs to leverage UCaaS (unified communications as a service), forcing executives to jump into one of the fastest-growing segments in the supply chain. UCaaS is a cloud delivery model that offers a variety of communication and collaboration applications and services, including providers such as RingCentral, Nextiva, 8x8 Inc., and Microsoft, to third-party cloud service providers, such as Verizon, AT&T, and BT. For the uninitiated, UCaaS was born out of four distinct technological phases that drove the need to have unified communications: The Rise of the Phone and E-mail For a long time, a company’s electronic communications consisted of two main parts--the phone and e-mail, thanks to the rise of the Internet. Having both a phone and Internet, allowed for a business to literally "be connected" to the rest of the world in a single location (before the Internet expanded to infinite locations). As technology has evolved since the 1990's, the communication needs of businesses and the average entrepreneur have grown. With the voluminous amount of information being shared and distributed on a daily basis, tracking and locating where information is coming from is essential to complying with data privacy laws, but also staying vigilant and organized. A one-stop-shop of information coming in and out would eventually be a universal demand. #3 - Instant Messaging (yes, ICQ and AIM) Millennials everywhere know instant messaging (IM) was a game-changer for the ways in which they communicated with family and friends. Instant messaging grew tremendously from the late 1990s (thanks to AOL) onward, when a small Israeli-based team, Mirabilis, made , the very first instant messaging platform publicly available. ICQ A year after ICQ was made available, AOL released its IM platform, AOL Instant Messenger (AIM). And here we are 23-years later with Facebook Messenger (just without the buddy list and endless variations of a screen name that a person could create). #4 - VOIP/Video Conferencing Platforms (Skype, Zoom, etc) Since IM took off, it paved the way for new technologies like e-mail, phone calls, group chats and video conferencing to take place, making it possible for remote communication from anywhere in the world, with very little centralization. What we basically ended up with was a number of communication channels coming from every direction without being able to group the information in a single location. Thus the idea for UCaaS was born. How Our Biggest Communication Platforms Are Using UCaaS UCaaS offers the opportunity to integrate multiple communication methods through a single cloud provider, including enterprise messaging, telephone communication, and video conferencing, which facilitates team communication. Think about the Slack and Microsoft Teams messaging platforms. This type of platform can then be integrated into call center services, such as call routing, and call centers, with additional functionality when combined with phone dialing software such as Avaya, Vonage, RingCentral, among others. One of the leading companies out there, Nextiva, a voice-over-internet-protocol (VOIP) company and UCaaS SMB specialist , Eric Martorano as the company’s newest Chief Revenue Officer, who will be overseeing Nextiva’s global revenue strategy and go-to-market strategy initiatives as he leads Nextiva’s sales organization. announced that it has appointed Microsoft’s former general manager Bringing to the table his extensive experience with Microsoft in leading direct and indirect sales and marketing teams, executing high-growth channel and distribution strategies, and taking industry-leading products to market, Martorano intends to take on his competitors as the global coronavirus pandemic continues. “We go head-to-head every day with RingCentral, 8x8, Vonage, and they have pretty solid solutions, but the Nextiva solution just fits better squarely with the SMB customer,” said Martorano, Nextiva’s new CRO effective today. “It was built with the SMB customer in mind. It has the ability to scale upwards into the enterprise, but one of the differentiating factors with Nextiva is when we build our products, we think about how we can make a difference with the SMB customer. … I do feel like Nextiva has something that Intermedia doesn’t with our NextOS. When you take a look at what we’re bringing to market, this is something special that the channel is going to really embrace.” Prior to leaving Microsoft, Martorano served as the CEO of Accordo Group, which was recently acquired by MarketStar. Currently, he sits on the Board of Directors for Velosio, one of the largest Microsoft Dynamics 365 partners worldwide. In a brief conversation with Nextiva’s CEO, Tomas Gorny, the company expressed excitement as Martorano joins the team, sharing that “as we continue to bring innovative products to the market, we look forward to Eric focusing on scaling our sales organization and our partner community, two important areas that will help accelerate our innovation in connected communication.”

In case you haven't been keeping up with the latest economic news, the US recently achieved its so-called soft landing, avoiding recession and seeing continued growth. That doesn't mean, however, that the pandemic and its economic upheaval didn't leave a lasting mark on the US economy. In fact, it wrought quite a few changes that seem to now be permanent features of the economic landscape. For one, it made remote and hybrid work not only acceptable for any business that wants to attract top talent. For another, it drove an of AI and automation technologies. But for the average worker, it did something far more profound—it created a . but an absolute necessity explosion in the adoption record wave of entrepreneurship The thing is, however, if you dig down beneath the topline entrepreneurship data, you'll find another interesting tidbit. It's that the majority of the new businesses in the US—a full eight in ten—consist of an owner and zero employees. In other words, what we're really seeing is a wave of taking root. As a solopreneur myself, that's something I can immediately identify with. And as a dedicated technology evangelist, I thought it would be helpful to help others wishing to take the solopreneurship plunge increase their odds of success. With that in mind, here are four types of digital tools every solopreneur should have in their arsenal before launching a solo business. solopreneurships 1. A Unified Communications Tool One of the biggest challenges associated with running a solo business is that you never have enough bandwidth to do your actual revenue-generating work while keeping in touch with clients and potential clients. As it turns out, though, there's a solution for that. It's called a . Unified Communications as a Service (UcaaS) platform They're cloud-based solutions that put multichannel communications tools like voice, video, SMS, Email, and chat into a single interface. This eliminates the time you'd otherwise waste switching from app to app, trying to make sure you don't leave a customer hanging when they reach out to you. Plus, there's a UcaaS platform for virtually every communication style. And due to intense market competition, you won't go bankrupt by subscribing to the one you want. Personally, I use , but that might be overkill for someone who's just starting out. For a great entry-level option with room to grow, check out , too. NextivaONE 8x8 2. Accounting Software If there's one thing you can't afford to do wrong as a solopreneur, it's keeping track of your business's finances. This is because new solopreneurs often struggle with setting prices and understanding operating costs. Without rock-solid accounting data to guide your decisions, you run the risk of without even realizing you're doing it. operating at a loss The good news here is that many of today's best accounting software providers have products and subscriptions aimed at solopreneurs—and they're quite inexpensive. There are even some, like the solution offered by , that don't cost anything at all for just the essentials. However, other options, like the one from , might be a better fit with its beginner-friendly tools and interface. Wave Accounting FreshBooks 3. A Document Management Solution Next is a digital tool type that advisory articles like this one often skip over. However, it's one that you will certainly miss if you don't have it: a solution. The reason is simple. As a solopreneur, you're responsible for managing every aspect of every client project. That includes the intake of customer data, documents, and other assets. Plus, you have to keep them organized and available at a moment's notice. You'd be shocked at how much of your time this single task will take up. document management To avoid wasting your precious time, you can choose and adopt a document management solution that suits your needs. If you do the kind of work that only requires basic client data collection, you might use something like a combination of for file sharing and for information intake. However, if you're offering something like legal/accounting services or web design, where client information exchange is more important, sensitive, and/or intense, check out a instead. Dropbox Google Forms solution like Gatheroo 4. Project Management Software Another digital tool you won't want to live without as a solopreneur is software. It's the only way you'll be capable of keeping track of multiple jobs at once without getting your wires crossed. Here again, you won't have any difficulty finding a solution that fits your specific line of work and preferred workflow. project management For starters, you could opt for a . It's infinitely adaptable, and you can configure it to support virtually any kind of project or task. Or, you can go with a tried-and-true solution like , which you may already be familiar with if you've worked for a mid-sized to large business in the past decade. It even has a free tier, which might be perfect for you as you begin your solopreneurship journey. solution like ClickUp Trello Let Your Solopreneur Adventure Begin If you arm yourself with the right tools and assistive technologies before you launch your solo venture, you stand a better chance of having a rewarding experience, both professionally and financially. Plus, you'll have an easier time managing your workload and avoiding burnout, which is an all-too-common way for solo businesses to come to an end. I can't tell you how much I wish someone had tipped me off to how much easier running a one-man operation could be with the above tools. So, enjoy the benefit of my experience, and best of luck as you begin your solopreneur adventure!

Websites connected by links are seen as info points connected by nodes. This was the primary generation of SEO.

In this article, we will tackle a question: Does Vue.js support multiple event listeners? Our journey will take us deep into the mechanics of Vue.js, unraveling some intriguing undocumented behaviors along the way. Let's begin with a closer look at the official documentation on "Event Handling" in Vue.js. The primary method of attaching an event listener is through the syntax, which can also be simplified as . v-on:click="handler" @click="handler" In this syntax, the refers to a reference to a function. Additionally, in the "Inline Handlers" section, it's highlighted that you can employ arbitrary JavaScript code directly within the attribute. handler For instance, you can use to increment a variable. An important note is provided in the "Method vs. Inline Detection" section, which indicates that: @click="count++" The template compiler detects method handlers by checking whether the value string is a valid JavaScript identifier or a property access path. v-on So, does Vue support multiple listeners? The answer seems to lean towards no, but it's not entirely clear-cut. Let recap it with the code: <script setup>
import { ref } from 'vue';

const count = ref(0);
function inc() { count.value += 1; }
</script>

<template>
  <h3>{{ count }}</h3>
  <button @click="count++">Incremenet by count++</button>
  <button @click="inc">Incremenet by ref</button>
  <button @click="inc()">Incremenet by call</button>
  <button @click="() => inc()">Incremenet by lambda</button>
</template> Now, let's within the Vue SFC Playground to closely examine how the Vue.js compiler has compiled these listeners. take a plunge into the JS tab We will encounter the following code snippet (I've omitted the portions for the sake of readability): _cache[0] || (_cache[0] = $event => (count.value++)) _createElementVNode("h3", null, _toDisplayString(count.value), 1 /* TEXT */);

// @click="count++" will be compiled to...
_createElementVNode(
  "button",
  {
    onClick: ($event) => count.value++,
  },
  "Incremenet by count++",
);

// @click="inc" will be compiled to...
_createElementVNode("button", { onClick: inc }, "Incremenet by ref");

// @click="inc()" will be compiled to...
_createElementVNode(
  "button",
  {
    onClick: ($event) => inc(),
  },
  "Incremenet by call",
);

// @click="() => inc()" will be compiled to...
_createElementVNode(
  "button",
  {
    onClick: () => inc(),
  },
  "Incremenet by lambda",
); The behavior is indeed intriguing. When a reference to is passed, the compiler simplifies it to . However, for , and , the compiler follows a distinct route. It encapsulates the code enclosed within the template's into a lambda function and then proceeds to execute it exactly as it's written. inc { onClick: inc } count++ inc() () => inc() " This observation offers valuable insight: if the compiler wraps code within a lambda, we can leverage native JavaScript capabilities to call multiple functions within a single expression using or . Let's try it. fn1(); fn2() fn1(), fn2() We will introduce another function, , which will invoke the native function and pass into it. You can access the updated Playground . showAlert() alert() count.value here Here is the code: // @click="count++, showAlert()" will be compiled to...
_createElementVNode(
  "button",
  {
    onClick: ($event) => (count.value++, showAlert()),
  },
  "Increment by count++",
);

// How to pass multiple refs?
_createElementVNode("button", { onClick: inc }, "Increment by ref");

// @click="inc(); showAlert()" will be compiled to...
_createElementVNode(
  "button",
  {
    onClick: ($event) => {
      inc();
      showAlert();
    },
  },
  "Increment by call",
);

// @click="() => (inc(), showAlert())" will be compiled to...
_createElementVNode(
  "button",
  {
    onClick: () => (inc(), showAlert()),
  },
  "Increment by lambda",
); For , , and , everything works fine, allowing us to call multiple functions for a single event. @click="count++, showAlert()" @click="inc(); showAlert()" @click="() => (inc(), showAlert())" The issue arises when dealing with the case. How can we pass multiple into the handler? The official documentation is notably silent on the topic of passing multiple references. ref refs @click="..." It appears that this feature might not be supported, leaving us unable to achieve this behavior directly. To explore this further, let's experiment with the two initial approaches that come to mind: and , and observe how they are compiled by Vue.js. fn1, fn2 [fn1, f2] // @click="inc, showAlert" will be complied to...
_createElementVNode("button", {
  onClick: $event => (inc, showAlert)
}, "Multiple refs 1");

// @click="[inc, showAlert]" will be complied to...
_createElementVNode("button", {
  onClick: $event => ([inc, showAlert])
}, "Multiple refs 2") Unfortunately, both attempts did not yield success. Vue.js compiles these expressions in a manner that involves encapsulating the code enclosed within the template's . This approach is consistent with the behavior we previously uncovered. " Let's take a step back and examine the scenario where we simply pass a function identifier without any accompanying braces in the event handler. () // @click="inc" will be compiled to...
_createElementVNode(
  "button",
  { onClick: inc },
  "Incremenet by ref",
); Vue simply maps to . Now, let's recap the rule we extracted from the documentation. inc onClick The template compiler detects method handlers by checking whether the value string is a valid JavaScript identifier or a property access path. v-on Incorporating the insights gained from the above, we can rephrase this rule as follows: If the string within the template's or , is recognized as a valid JavaScript identifier, Vue.js compiler will directly map it to . v-on @event { onEvent: <Valid JS Identifier> } Or like this: Using only the name of a variable or a function will result in direct mapping. Our revised definition omits any reference to a "method" handler; it purely states that when a valid identifier is used, it is directly passed as is. This implies that you can even pass a numeric value like to an handler, provided you first create an identifier (in other words, a variable) that's bound to the value. 1337 onClick Passing a number as a handler clearly won't yield the desired results. However, as we recall, our aim is to pass multiple handlers as an array of refs. Given our newly established understanding, this is achievable. However, the prerequisite is to create a "valid JS Identifier (variable)" to store the reference to the array. Let's put this into action and see the results. . An interesting observation unfolds. Take a look here Firstly, using a "valid JS Identifier (variable)" named , we successfully pass an array to , and it gets mapped accordingly. multiple onClick However, TypeScript expresses its discontent. It raises an error stating: Type '(() => void)[]' is not assignable to type '(payload: MouseEvent) => void'. Type '(() => void)[]' provides no match for the signature '(payload: MouseEvent): void'.ts(2322) In essence, the types within Vue.js prevent us from passing an array of functions as a click listener. Let's set this aside for now, and simply click on the button to observe whether both listeners will be invoked. And yes, they are. We witness the counter value incrementing, followed by the appearance of the alert. But hold on, there's a puzzle to solve. Why is this functioning? What's going on behind the scenes? To comprehend this, we must delve deeper and grasp the mechanics underlying the translation of Vue's , created by the function, into a native DOM element. The key lies in exploring the source code of Vue.js itself! VNode _createElementVNode When we call the function in our main or , it triggers a chain of events that leads to the execution of the function (look for function ). createApp() app.js index.js createRenderer() createApp here This sequence results in the formation of an instance, complete with a method. This method establishes an association with the renderer (see ). This renderer's primary task is to convert our s into the native DOM elements we interact with. app mount() ensureRenderer() here VNode Here's an overview of the key steps: We compile our template, resulting in a series of calls. _createElementVNode() These calls build our Virtual DOM, generating s. VNode The renderer then traverses these nodes, converting them into native DOM elements. As the renderer transforms s into native DOM elements, it performs additional tasks using the object of a through the method. VNode props VNode patchProp Additionally, note that the function is invoked with , encompassing a "patched" . Let's delve into this for further understanding. createRenderer(rendererOptions) extended rendererOptions patchProp method export const patchProp: DOMRendererOptions['patchProp'] = (
  // Omitted params...
) => {
  if (key === 'class') {
    patchClass(el, nextValue, isSVG)
  } else if (key === 'style') {
    patchStyle(el, prevValue, nextValue)
    // Keep in mind that we provide an object containing on<EventName> keys.
    // `isOn(key)` will return true for these keys.
  } else if (isOn(key)) {
    if (!isModelListener(key)) {
      // If the listener isn't intended for `v-model`, we utilize the `patchEvent` mechanism.
      patchEvent(el, key, prevValue, nextValue, parentComponent)
    }
  } // ... We can interpret the code as follows: "If a prop is , apply special handling based on values. If a prop is , implement special handling based on values. And if a prop begins with , perform specific actions using ." class class style style on patchEvent Let's direct our attention to the . We've reached the bottom where Vue establishes native event bindings through the browser's method. However, prior to this step, there are additional operations in play. patchEvent method addEventListener() The high-level call chain is as follows: is invoked. patchEvent() It proceeds to call in order to generate an invoker function. createInvoker() Inside the , we invoke , passing a wrapped version (altered by ) of the value provided in the event handler. invoker callWithAsyncErrorHandling patchStopImmediatePropagation @click="..." Now, let's examine to uncover the answer to the question: "Why does passing multiple refs to a function work?" patchStopImmediatePropagation function patchStopImmediatePropagation(
  e: Event,
  value: EventValue
): EventValue {

  // If the value is an array, there's even more to explore! 
  // We can call $event.stopImmediatePropagation()
  // and other functions within the array won't be invoked.
  if (isArray(value)) {
    const originalStop = e.stopImmediatePropagation
    e.stopImmediatePropagation = () => {
      originalStop.call(e)
      ;(e as any)._stopped = true
    }

    // This is where the actual function calls occur.
    return value.map(fn => (e: Event) => !(e as any)._stopped && fn && fn(e))
  } else {
    return value
  }
} And here we are, fully informed. Even though the official documentation and TypeScript might not explicitly endorse it, we've found a code segment that effectively allows us to pass event listeners using an array of function references. There is the that introduced this functionality. It appears that at some point in the past, there might have been an intention to enable the capability of passing multiple listeners. However, as it stands now, this remains an undocumented feature. commit Lastly, let's address the question we initially posed: Does Vue support multiple listeners? The answer hinges on your interpretation of "supports". To summarize: We can invoke multiple functions using , and there's a for that. fn1(); fn2() test We can also invoke them using . fn1(), fn2() We can pass it through an array if stored in a variable. Alternatively, given the newfound knowledge, we can even call them like so: <template>
  <button @click="[fn1, fn2].forEach((fn) => fn($event))">
    Click!
  </button>
</template> Also published here
