The COVID-19 pandemic has spurred significant changes in the way businesses to operate. Particularly, it the growth of e-commerce, including in the pharmaceutical space. As consumer needs and preferences have evolved, e-commerce has become crucial to healthcare delivery. In this post, I will discuss some of the key tech trends in pharmaceutical e-commerce and the development of online pharmacies. has accelerated Online Pharmacy Market Pharmaceutical e-commerce offers a simple, effective, and transparent way to purchase prescription drugs in both B2B and B2C settings, which makes it an especially attractive, fast-growing market. No wonder the world’s largest e-commerce corporations have doubled down on their online pharmacy investments, followed closely by big pharmaceutical companies that are going digital. Here’s a closer look at this global trend. the global e-pharmacy market size is expected to reach US$ 351.9 billion by the end of 2033. It is anticipated to create lucrative growth opportunities over the forecast period by registering a CAGR of 14.3% from 2023 to 2033. According to Future Market Insights Take , an online pharmacy service offered by the e-commerce giant Amazon. It a relatively recent addition to the company’s core platform and aims to make filling prescriptions as easy and convenient as other transactions performed on Amazon. Prime members have access to free two-day delivery of orders and to savings of up to 80% off generic and 40% off branded medications when not paying using insurance. Amazon Pharmacy has become Another major US-based player, , has been in its digital offerings, including its CVS app that allows customers to refill prescriptions, set medication reminders, and access health resources. CVS Health investing heavily Meanwhile in China, , also known as AliHealth, has an online pharmacy platform that offers prescription medications and over-the-counter products. The company also provides telemedicine services and a health management app. Alibaba Health Information Technology launched is a similar project in India. PharmEasy's mobile customers to order medications and other healthcare products, as well as book lab tests and consult with a physician. PharmEasy app allows Harnessing the Cutting-Edge Tech As the above examples suggest, the growth of pharmaceutical e-commerce falls within a wider trend toward the digitization of the healthcare industry. Both pharmacies and healthcare providers technological innovations in areas including telemedicine, AI, blockchain, and the IoT to develop and deliver novel treatments and services. effectively harness Integration of technologies gives rise to a new type of service, an e-pharmacy, which potentially can transform beyond its initial scope of selling medications online. By collaborating with other healthcare providers, such as hospitals and clinics, e-pharmacies can offer patients seamless access to a wide range of healthcare services and serve as a central hub for a comprehensive healthcare platform. This emerging trend has the potential to transform the way we think about healthcare, by providing patients with a convenient and holistic approach to managing their health. Artificial Intelligence The biggest advantage of AI-driven healthcare is personalisation. E-commerce companies are to develop personalised treatment plans, product recommendations, email marketing, and promotions. AI is also being used to with chatbots and virtual assistants that can answer customer queries and provide customer support. using AI improve the customer experience When it comes to treatment plans, AI-assisted pharmacists can use data from a patient's medical history, genetics, and lifestyle to manage both acute and chronic conditions. This can help optimise medication therapy and reduce the risk of adverse events. The patient experience can be further enhanced with AI-enabled chatbots and virtual assistants that can respond to customer queries and provide support. Furthermore, AI can be used to help patients manage their prescribed treatment by sending out alerts that remind them to take medications or refill prescriptions, as well as warnings about potential drug interactions or side effects. Telemedicine Many online pharmacies—including Amazon, , , and CVS, among others—already provide telemedicine consultations. Telemedicine is the practice of using telecommunication and information technologies to provide remote clinical services. This technology can help online pharmacies offer virtual consultations and remote monitoring to patients, increasing access to medical care. Hims Sesame The Internet of Things IoT devices can monitor patient health and transmit data to healthcare providers, allowing for more personalised treatment plans. With regard to pharmacies, IoT devices can be used to monitor the temperature and humidity levels of pharmaceutical products during shipping and storage. Blockchain In the pharmaceutical industry, Blockchain technology can be utilised to improve supply chain transparency and prevent counterfeiting. With blockchain, e-commerce companies can track the movement of pharmaceutical products from the manufacturer to the end consumer, ensuring that the products are authentic and have not been tampered with. Each transaction or movement of the product is recorded on the blockchain, creating an immutable trail of the product's journey. If a pharmaceutical product has been compromised during transportation, the blockchain will show an irregularity in its movement, allowing the e-commerce company to investigate and take appropriate action. One example of a company using blockchain in the pharmaceutical industry is Blockpharma, a French startup that is using blockchain and ML to combat medicine counterfeiting. Alibaba Case A more prominent example is the case of Alibaba Health Information Technology, a subsidiary of Chinese online retail giant Alibaba. The company has created a one-stop healthcare platform and provides a comprehensive range of clinical services, including online consultation, medicine delivery, and appointment booking. Aside from conventional medical care, Alibaba Health has also partnered with Traditional Chinese Medicine hospitals so that patients can consult with traditional healthcare practitioners remotely and receive prescribed herbal medicine through Alibaba Health's logistics network. Additionally, Alibaba Health has developed a medication traceability system to ensure the authenticity and safety of the drugs sold on their platform. This system uses blockchain technology to track the entire supply chain of a drug, from production to distribution. Alibaba Health's online pharmacy business has been particularly important during the COVID-19 pandemic, when online consultations and medicine delivery have made it easier for patients to access the healthcare they need while minimising their exposure to the virus. This makes Alibaba Health's e-commerce pharmaceutical business a prime example of the potential for technology to revolutionise healthcare. By investing in advanced tech, Alibaba Health is transforming the way medical care is delivered in China and setting a precedent for the rest of the world. To conclude The COVID-19 pandemic has accelerated the growth of e-commerce, particularly in the pharmaceutical space, as consumer needs and preferences have evolved.  The growth of pharmaceutical e-commerce falls within a wider trend toward the digitization of the healthcare industry, which integrates technologies such as telemedicine, AI, blockchain, and the IoT to develop and deliver novel treatments and services. These technologies can help personalise treatment plans, improve the customer experience, increase access to medical care, monitor patient health and transmit data, improve supply chain transparency, and prevent counterfeiting. The case of Alibaba Health Information Technology demonstrates how a one-stop healthcare platform can provide a comprehensive range of clinical services, including online consultation, medicine delivery, and appointment booking.

Tech Trends Driving E-Pharmacy

Welcome! Happy to see you in the fifth part of my Vuejs Amsterdam Conference 2022 summary series, in which I share a summary of all the talks with you. You can read my JSWorld Conference 2022 Summary series (in four parts) , where I summarized all the first day's talks. You can also find the previous Talks of the Vue Amsterdam conference 2022 in my blog. here (Recurring) Introduction After two and a half years, JSWorld and Vue Amsterdam Conference were back in Theater Amsterdam between 1 and 3 June, and I had the chance to attend this conference for the first time. I learned many things, met many wonderful people, spoke with great developers, and had a great time. On the first day the JSWorld Conference was held, and on the second and third days, the Vue Amsterdam. The conference was full of information with great speakers, each of whom taught me something valuable. They all wanted to share their knowledge and information with other developers. So I thought it would be great if I could continue to share it and help others use it. At first, I tried to share a few notes or slides, but I felt it was not good enough, at least not as good as what the speaker shared with me. So I decided to re-watch each speech, dive deeper into them, search, take notes and combine them with their slides and even their exact words in their speech and then share it with you so that what I share with you is at least at the same level as what I learned from them. A Very Important Point and I have only tried to learn them so that I can turn them into these articles. Even This means if you learn something new, it is because of their efforts. (So if you see some misinformation blame them, not me, right? xD) Everything you read during these few articles is the result of the effort and time of the speaker itself, many of the sentences written in these articles are exactly what they said or what they wrote in Slides. Last but not least, I may not dig into every technical detail or live codings in some of the speeches. But if you are interested and need more information, let me know and I’ll try to write a more detailed article separately. Also, don’t forget to check out their Twitter/Linkedin. you can find the program of the conference. Here Reusable Widgets That Work! - Head of Accessibility Training and Sr Manager of Accessibility Engineering at CVS Health Maria Lamardo Vue.js is an amazing framework that allows you to quickly build reusable components. We can leverage this to build accessible reusable widgets with the help of ARIA (Accessible Rich Internet Application). Using ARIA roles and attributes, we can improve the accessibility of certain elements by providing additional semantics. In this talk, we will go over how to follow the specifications and build accessible and reusable tabs, accordions, toggle buttons, and modal dialogs that work for everyone! Modal All the things that you need to know about ARIA are well documented in and it is recommended to read, but here is an abstracted version of it. W3C Modals Design Considerations It must have a button that closes the dialog. The content outside of the dialog should be obscured with visual styling like a grey background. Make sure you prevent users from interacting with content outside of the dialog. Modals Opening Focus Interaction When a dialog opens, focus can be set on either the first focusable element, or a static element at the top of the dialog to make content easier to read and ensure that all the content remains in view, or the most frequently used element if interactions are limited to providing information or continue processing. You don’t wanna set focus to something that is going to be destructive for the user, for example, let’s imagine you have an interaction where you open a modal to delete your account. You don’t want to set the first focus on “Yes, delete my account”. Modals Closing Focus Interaction When a dialog closes, the focus is set on the element that invoked the dialog, or when it doesn’t make sense you can set the focus on a different element, like an element that provides logical workflow if invoking element no longer exists, or on the next element if there is a subsequent step in the workflow following dialog task completion, especially if immediately reopening dialog is very unlikely. Modals Keyboard Interaction Tab Moves focus to next tabbable element in modalLooping around to first element Shift + Tab Moves focus to previous tabbable element in modalLooping around to last element Escape Closes the dialog Modals Technical Considerations Dialog container should have: Role of dialog set to true. aria-modal or referring to dialog title, this is going to help assistive technologies figure out what the naming of this element will be. aria-label aria-labelledby Optionally you can set to any description. aria-describedby All elements required to operate the dialog should be descendants of the element that has a dialog role. <div 
	role="dialog" 
	aria-modal="true"
	aria-labelledby="title"
	aria-describedby="description"
>
	<h2 id="title">Title of the dialog</h2>

	<p id="description">Information provided by the dialog.</p>

	<button aria-label="close">×</button>
</div> On the mac, you can Activate Voice Over which is the default mac screen reader by clicking Command + F5, and then you can go through your page and test it. Also in chrome Dev-Tools, there is an accessibility tab that has some cool accessibility information. With that, you can open and check it out, and is the code. this example here Toggle Buttons If you want the full information you can find it on the website. W3C Buttons A is a widget that enables users to trigger an action or event, such as submitting a form, opening a dialog, canceling an action, or performing a delete operation. button In addition to the ordinary button widget, WAI-ARIA supports 2 other types of buttons: Toggle buttons Menu buttons Toggle Buttons Design Considerations A two-state button that can be either off (not pressed) or on (pressed). To tell assistive technologies that a button is a toggle button, specify a value for the attribute . aria-pressed The label on a toggle mustn't change when its state changes; if the label changes in the design, there is no need for the aria-pressed attribute. Toggle Buttons Focus Handling If activating the button does not dismiss the current context, then focus remains on the button after activation. If activating the button opens or closes a dialog, then follow the dialog pattern. If the button action indicates a context change, you can move focus to the starting point for that action If the button is activated with a shortcut key, then focus usually remains in the context from which the shortcut key was activated Toggle Buttons Keyboard Interaction Enter Activates the button Space Activates the button Toggle Buttons Technical Considerations The Toggle button must have the role of . button Make sure that the button has an accessible name. You can set to any description. aria-describedby You can add set to true if action is unavailable. aria-disabled The toggle button has an state. aria-pressed <button aria-pressed="false">
  Mute
</button> Here is a good that you can check out and is the code. example here Accordions is the complete documentation. Let’s take a look at its main points. Here Accordions Design Considerations Vertically stacked set of interactive headings that each contain a title, content snippet, or thumbnail representing a section of content Accordion Header: Label for or thumbnail representing a section of content that also serves as a control for showing, and in some implementations, hiding the section of content. Accordion Panel: Section of content associated with an accordion header. Accordions Keyboard Interaction Enter or Space Expands associated collapsed panel, optionally collapses other opened panelCollapses associated expanded panel; if the implementation allows. Tab Moves focus to the next focusable element Shift + Tab Moves focus to the previous focusable element Down Arrow (Optional) Moves focus from the accordion header to the next accordion header Optionally loops back to the first accordion header. Up Arrow (Optional) Moves focus from accordion header to the previous accordion header Optionally loops back to last accordion header Home (Optional) Moves focus from an accordion header to the first accordion header End (Optional) Moves focus from an accordion header to the last accordion header Accordions Technical Considerations Make sure that Each accordion header button has: wrapped in a heading set to the ID of the corresponding accordion panel content aria-controls set to true if corresponding panel content is visible aria-expanded set to true if the collapsing accordion is not permitted aria-disabled Each panel content has and to the corresponding header button (Optional) role region aria-labelledby Avoid using the region role in circumstances that create too many landmark region Accordions Code Example <h3>
   <button
     aria-expanded="true"
     class="Accordion-trigger"
     aria-controls="sect1"
     id="accordion1id"
	 >
		Accordion 1
   </button>
 </h3> <div
   id="sect1"
   role="region"
   aria-labelledby="accordion1id"
   class="Accordion-panel"
>
	Content Placeholder
</div> Here is a good and its . example code Tabs You can see Tabs’ full documentation on . W3C Tabs Design Considerations Tabs are a set of layered sections of content, known as tab panels, that display one panel of content at a time. A set of tab elements contained in a element Tab List: tablist An element in the tab list that serves as a label for one of the tab panels and can be activated to display that panel Tab: The element that contains the content associated with a tab Tab panel: It is recommended that tabs activate automatically when they receive focus as long as their associated tab panels are displayed without noticeable latency. Tabs Keyboard Interaction Tab Places focus on the active tab element when user moves into the tab list Left Arrow (Horizontal tabs) Up Arrow (Vertical tabs) Moves focus to the previous tab; looping to the last tabOptionally, activates the newly focused tab Right Arrow (Horizontal tabs) Down Arrow (Vertical tabs) Moves focus to the next tab; looping to the first tabOptionally, activates the newly focused tab Space or Enter Activates the tab if it was not activated automatically on focus Shift + F10 When focus is on a tab that has an associated popup menu, opens the menu Tabs Optional Keyboard Interaction Home (optional) Moves focus to the first tabOptionally, activates the newly focused tab End(optional) Moves focus to the last tabOptionally, activates the newly focused tab Delete(optional) If deletion is allowed, deletes (closes) the current tab element and its associated tab panel, sets focus on the tab following the tab that was closed, and optionally activates the newly focused tab Tabs Technical Considerations Element containing a set of tabs must have or . Role of Tablist: aria-labelledby aria-label The element that serves as a tab must have paired to the associated tabpanel, the active tab should have the state aria-selected set to true; all other tabs are set to false. Role of Tab: aria-controls And it should have the property aria-haspopup set to either menu or true if a tab element has a pop-up menu. Element containing content panel for a tab should have aria-labelledby paired to associated tab, and set aria-orientation to vertical or horizontal (default). Role of Tabpanel: Tabs Code Example <div role="tablist" aria-label="Tabs Example">
  <button
    role="tab"
    aria-selected="true"
    aria-controls="tab1-content"
    id="tab1"

Tutorial: Swift and SwiftUI for Data Science iOS Development

A short article about Golang aimed for newer developers or those who have not spent much time researching the language and would like a short, concise, well thought-out, and original introduction. All code written is within a repl. Go is real cool, something that is extra cool about it is that it is the highest paying technology according to Stack Overflows 2017 dataset. The average pay for a Go developer is ~ : 110k a year this link right here! (Technology -> Top Paying Technologies on sidebar for verification) Hot damn! But, that is only a piece of the reason to learn Go. The main reason is this: Why? Well, is a well thought out modern language that utilises many of the best practices of languages created before it. learning it is only going to speed up your understanding of fundamental computer science topics. Golang programming It is also a language that was made by Google to take care of the massive amount of data and problems associated with handling their search engine that almost everybody uses. On another note, to fully learn Go is to learn how to build software that provides answers for low level problems. Another way to say it is software that provides services for other software. In a way, if you know Golang then you know how to build programs that touch the root of this field. Let’s delve into some code. The story begins as so: It is now, this time, as in, 2018. But suddenly time jumps… 240 years ahead. As if you were Austin Powers frozen all this time. And it is up to you to suddenly save the universe. With a twist at the end. I wrote a piece of code, around 150 lines, that tells the very short story in its entirety (lots of prints) which I will put at the end. I am going to go through the code from start to finish prior. Starts simple, then gets a bit dense. package main import ("fmt""time""strconv""io""strings") ? All Go source code is part of a package, and each file necessitates a package statement. is the file where the code runs. Other package files are modules imported into package main. The modules are reusable pieces of code to use or implement within . package main package main package main So, the imported modules contain source code which I will use within this file. type Aliens struct {species int} type NotEarthling struct {total intcentury stringthingamajig string} type Earthling struct {total intcentury stringname stringage int64} type WordSpaceship struct {health stringweapon string} type NumberSpaceship struct {health intweapon int} Multiple structs with different usages. ? It is how you create an object that can have different types for each value. The key is the word written, a string. Though, each key must have the specified type, it is not dynamic. What’s a struct The other major way to create objects is with a . Though, in that case every key must be a single type as well as the values: map all keys must be string, all values must be int make(map[string]int) So, in maps each key must be of one type and each value must be of one type. In structs, different types are allowed for each value. var you = Earthling{century: "21st", name: "you", age: 24} func main() {defer fmt.Println("Is this all a dream?") now := time.Now()  
nanos := now.UnixNano()  
fmt.Printf("Right now it is: %v! \\nPop! AHHHHH\\n\\n", now) The occurs in the global scope, so it must be initialised with the keyword. This is to initialise structs. Notice that I specified the key and set it’s value to the corresponding type written in the struct definition. Notice how I have not initialised every key/value (you not need to). variable declaration var one way ? This creates a last-in-first-out stack of function invocations to be called the completion of . I say a stack as can be called multiple times and each time it is called the last function pushed onto the stack is called first. defer after func main() {...} defer This is to say that the type will be figured out dynamically by the compiler. As in, when initialising a value to a variable in this way you do not need to specify the type, the only way to do so. :=, what is this? returns this: 2017–12–28 01:41:05.240081928 +0000 UTC time.Now() returns this: 1514425756675856179 which is the amount of nanoseconds that have occurred since the creation of Golang 8 years ago. now.UnixNano() allows logging out values in varying forms: Printf gives the default value %v gives the type of the value %T are two of the major forms. Still in the function main below. nanos = nanos + 7600000000000000000  

years := (nanos - now.UnixNano())/1000000000/31622400  

now = time.Unix(0, nanos)

fmt.Printf("And now it is: %v!\\nOh hell!\\n\\n", now) At the beginning one goes 7600000000000000000 nanoseconds into the future which is ~ 240 years. is a calculation, convert to seconds then to years. years will convert the nanoseconds to: 2258–10–29 00:55:56.675856179 +0000 UTC time.Unix(seconds, nano seconds) var e \[\]Earthling  
var ne \[\]NotEarthling

for i := 0; i < 70000; i++ {  
    e = append(e, Earthling{})  
}  

for i := 0; i < 44; i++ {  
    ne = append(ne, NotEarthling{})

aliens := Aliens{2}

futureEarthling := Earthling{len(e), "22nd", "The Future", 32141}  

futureNotEarthling := NotEarthling{len(ne), "99th", "Grok grok grok"} The keyword calls set a array (empty array) that can only be filled with the specified type. One cannot add ints, strings, etc. to this array. var zero valued In the following , I am to the arrays. for loops appending empty structs of the specified type There are only two alien species in this case. and . Earthlings NotEarthlings Notice, how is set to the struct without specifying the key, this is a shorthand, as long as you place the values in the corresponding order defined in the struct, in this case: , then the fields can be filled out in this way. futureEarthling Earthlings {int, string, string, int64} Now there is a function called attached to each object… lets check out that separate, not in main, function. Greet Earthling func (e *Earthling) Greet(y int64) string { century, \_ := strconv.ParseInt(e.century\[0:2\], 0, 64)

if century > 21 && century < 30 {

  age := strconv.FormatInt(you.age, 10)

  str := "Welcome to the future young Padawan, you are in the: " + e.century + " century. And I am: " + e.name + ". You are now... " + age + "years old. The world is under attack, and you have been revived to defend it! Big scary invader has something to say..."

  return str

} else {  
  e.age = e.age + y  
  return "Where am I???"  
} } Ok, so this corresponds to the existential crisis this person is going through, waking up so far into the future, and some random future guy that has something to say! Hmm… look at the top: . What’s this? Well, is going to be the instance of the object the method is called on. And the ? . I invite you to open the repl below, delete that and see what happens. (e *Earthling) e Earthling * This is a pointer * What it means is this: . If you do not, anything you do on will not alter the object within the main function. The pointer assures that the object can be altered. you.Greet(year) is creating a copy of _you_ unless you point at it’s memory address you We also have a new library in this code snippet… . This is the library to use when you want to change an int to a string, vice versa, or many other types. Go has so many data types… int, int8, int16, int32, int64. And all I named is int there, in other words, one can go on and on… type galore. strconv If you look closely, the entire reason I used a pointer was to alter the age of the young Padawan. numberShip := NumberSpaceship{100, 3}wordShip := WordSpaceship{"Read this to defeat me.", "Powerful words!"} wordAttack := make(chan int)finished := make(chan int) go func() {for {numberShip.health = numberShip.health - <-wordAttackif numberShip.health <= 0 {Extinction(&aliens)finished <- 0}}}() fmt.Println(Fight(&numberShip, &wordShip, wordAttack, finished)) Ok, first of all, the first parameter of both structs is their health. So, for the the health is 100, and for the the health is a sentence… …? I’ll go into that in the function at the bottom, , which uses what is called a . numberShip wordShip "Read this to defeat me" Fight Reader creates what is called a channel. A conduit to send/receive values. Sending is as so: , and receiving as: . make(chan int) <-wordAttack finished <- 0 is the creation of a When working with channels and goroutines in unison, the main thing to remember is that the goroutine continues So, let’s go check out where it is getting it’s values, the function. go func() {…}() goroutine. as long as the channel sends it values. Fight func Fight(ns *NumberSpaceship, ws *WordSpaceship, c, f chan int) string {x := len(ws.weapon)r := strings.NewReader(ws.health)b := make([]byte, ns.weapon)for {select {case c <- x:fmt.Println("Hit it!")case <-f:fmt.Println("He's finished!")return "\nYou saved time, space, eternity, everything!\n"}_, err := r.Read(b)if err == io.EOF {return "You failed, the universe is to end."}}} First, check out the function signature. The function was called by the variables memory address (with ). In the signature, the function expects a (ie. a variable) as the argument for both and . referencing & pointer referenced NumberSpaceship WordSpaceship Also, check out how both type is only written once. Parameter types can be grouped if they are next to one another and the same exact type. chan ints First, the library, this “implements simple functions to manipulate UTF-8 encoded strings.” In this function a will be created to read a string. strings reader Ok, the implementation of the string reader: returns a new that will read from s: . r := strings.NewReader(ws.health) Reader "Read this to defeat me" returns a byte slice of the length specified. is the value 3. b := make([]byte, ns.weapon) ws.weapon is more nuanced. can also be a variable name, let’s call it . If exists it means that the amount of bytes read by is to be returned to . But if left as is then one does not have to use the value returned. Otherwise, you have to, which is to say that So, for one, returns the amount of bytes read, and secondly it returns an error if and only if the entire string was read, in which case an (end of file) error is returned. Otherwise, it’s value is: . _, err := r.Read(b) _ n n Read n Go does not allow one to not use declared variables. Read io.EOF <nil> So, is the reader. is what the reading of the string is put into. is the function that is called to make that come about. r b Read So, to summarise the , and why it is being used, once the string is read the wins, and the loses. Very intense battle. Reader NumberSpaceship WordSpaceship A quick side note: is to say, do an infinite loop until the function returns. for {…} As for the attack of the . WordSpaceship is waiting on multiple communication operations, both channels, and . When one is ready to send out its data or receive data, it will continue to do so as long as the function does not return. select c f is to say, continually send the value of x to this channel. Then, going back to ’s goroutine, do this: to damage the ship. So, the channel is emptied of the x it just received. case <- x func main numberShip.health = numberShip.health — <-wordAttack channel receives a value and sends it out right after in the corresponding goroutine solely runs when f has a value associated to it and this only happens when this occurs in : , after the if statement. case <- f main finished <- 0 That’s the fight! And after the battle, whoever lost, well, their entire species goes extinct… this was how it was written, the logic is not combined in the real code as so though. type Aliens struct {species int} func Extinction(a *Aliens) {a.species = a.species - 1} func main() {aliens := Aliens{2}Extinction(&aliens)} Quite an intense bit of logic. And the entirety of what is logged out from the real code! Right now it is: 2017-12-28 21:40:35.066259304 +0000 UTC!Pop! AHHHHH And now it is: 2258-10-29 20:47:15.066259304 +0000 UTC!Oh hell! Where am I??? Welcome to the future young Padawan, you are in the: 22nd century. And I am: The Future. You are now... 264 years old. The Universe is under attack, and you have been revived to defend it! Big scary invader has something to say... Tord thaz geck hild quemp 240! He challenged you! You're the chosen one, so you must save the Universe! Jump on this spaceship. VRRRROOOOOOOOOOOOMMMMMMMM BOOM BOP BOOM BOP Hit it!Hit it!Hit it!Hit it!Hit it!Hit it!Hit it!He's finished! You saved time, space, eternity, everything! AHHH, the aliens left a bomb, the Universe is to disintegrate into nothingness! Some higher being sort of thing says: There are  0  sentient beings left alive. Was that all a dream? And the repl: _Powerful and simple online compiler, IDE, interpreter, and REPL. Code, compile, and run code in JavaScript, Python…_repl.it repl.it - GolangArticleFrozenSpaceGuy by @jerrymuzsik I highly recommend this if you are interested in learning more Go, great introductory documentation/practice problems! tour.golang.org A Tour of Go Thanks very much!
