JSJ 274: Amazon Voice Services and Echo Skills with Terrance Smith

JSJ 274 Amazon Voice Services and Echo Skills with Terrance Smith

On today’s episode of JavaScript Jabber, we have panelists Joe Eames, Aimee Knight, Charles Max Wood, and we have special guest Terrance Smith. He’s here today to talk about the Amazon Alexa platform. So tune in and learn more about Amazon Voice Services!

[01:00] – Introduction to Terrance Smith

Terrance is from Hacker Ferrer Software. They hack love into software.

[01:30] – Amazon Voice Service

What I’m working on is called My CareTaker named probably pending change. What it will do and what it is doing will be to help you be there as a caretaker’s aid for the person in your life. If you have to take care an older parent, My CareTaker will be there in your place if you have to work that day. It will be your liaison to that person. Your mom and dad can talk to My CareTaker and My CareTaker could signal you via SMS or email message or tweet, anything on your usage dashboard, and you would be able to respond. It’s there when you’re not.

[04:35] – Capabilities

Getting started with it, there are different layers. The first layer is the Skills Kit for generally getting into the Amazon IoT. It has a limited subset of the functionality. You can give commands. The device parses them, sends them to Amazon’s endpoint, Amazon sends a call back to your API endpoint, and you can do whatever you want. That is the first level. You can make it do things like turn on your light switch, start your car, change your thermostat, or make an API call to some website somewhere to do anything.

[05:50] – Skills Kit

Skills Kit is different with AVS. Skills Kit, you can install it on any device. You’re spinning up a web service and register it on Amazon’s website. As long as you have an endpoint, you can register, say, the Amazon Web Services Lambda. Start that up and do something. The Skills Kit is literally the web endpoint response. Amazon Voice Services is a bit more in-depth.

[07:00] – Steps for programming

With the Skills Kit, you register what would be your utterance, your skill name, and you would give it a couple of sets of phrases to accept. Say, you have a skill that can start a car, your skill is “Car Starter.” “Alexa tell Car Starter to start the car.” At which point, your web service will be notified that that is the utterance. It literally has a case statement. You can have any number of individual conditional branches outside of that. The limitation for the Skills Kit is you have to have the “tell” or “ask” and the name of the skill to do whatever. It’s also going to be publicly accessible. For the most part, it’s literally a web service.

[10:55] – Boilerplates for AWS Lambda

Boilerplates can be used if you want to develop for production. If you publish a skill, you get free AVS instance time. You can host your skill for free for some amount of time. There are GUI tools to make it easier but if you’re a developer, you’re probably going to do the spin up a web service and deal it that way.

[11:45] – Do you have to have an Amazon Echo?

At one point, you have to have the Echo but now there is this called Echoism, which allows you to run it in your browser. In addition to that, you can potentially install it on a device like a Raspberry Pi and run Amazon Voice Services. The actual engine is on your PC, Mac, or Linux box. You have different options.

[12:35] – Machine learning

There are certain things that Amazon Alexa understand now that it did last year or time before that like understanding utterances and phrases better. A lot of the machine learning is definitely under the covers. The other portion of it Alexa Voice Service, which is a whole engine that you have untethered access to other portions like how to handle responses. That’s where you can build a custom device and take it apart. So the API that we’re working with here is just using JSON and HTTP.

[16:40] – Amazon Echo Show

You have that full real-time back and forth communication ability but there is no video streaming or video processing ability yet. You can utilize the engine in such a way that Amazon Voice Services can work with your existing tool language. If you have a Raspberry Pi and you have a camera to it, you can potentially work within that. But again, the official API’s and docs for that are not available yet.

[27:20] – Challenges

There’s an appliance in this house that listens to everything I say. There’s that natural inclination to not trust it, especially with the older generations. Giving past that is getting people to use the device. Some of the programming sides of it are getting the communication to work, doing something that Alexa isn’t pre-programmed to do. There isn’t a lot of documentation out there, just a couple of examples. The original examples are written in Java and trying to convert it to Node or JavaScript would be some of the technical challenges. In addition, getting it installed and setup takes at least an hour at the beginning. There’s also a learning curve involved.

[29:35] – Is your product layered in an Echo or is your product a separate device?

Terrance’s product is a completely separate device. One of the functionality of his program is medicine reminders. It can only respond to whatever the API calls from Amazon tells you to respond to but it can’t do anything like send something back. It can do an immediate audio response with a picture or turn on and off a light switch. But it can’t send a message back in like two hours from now. You do want your Alexa device to have (verbally) a list of notifications like on your phone. TLDR, Terrance can go a little further with just the Skills Kit.

[32:00] – Could you set it up through a web server?

Yes. There are examples out there. There’s Alexa in the browser. You can open up a browser and communicate with that. There are examples of it being installed like an app. You can deploy it to your existing iPhone app or Android app and have it interact that way. Or you can have it interact independently on a completely different device like a Raspberry Pi. But not a lot of folks are using it that way.

[33:10] – Monetization

Amazon isn’t changing anything in terms of monetization. They make discovery a lot easier though. If you knew the name of the app, you could just say, “Alexa, [tell the name of the app].” It will do a lazy load of the actual skill and it will add it to your available skill’s list.

However, there is something called the Alexa Fund, which is kind of a startup fund that they have, which you can apply for. If you’re doing something interesting, there is a number of things you have to do. Ideally, you can get funding for whatever your product is. It is an available avenue for you.

[36:25] – More information, documentation, walkthroughs

The number one place to go to as far as getting started is the Amazon websites. They have the Conexant 4-Mic Far-Field Dev Kit. It has 4 mics and it has already a lot of what you need. You have to boot it up and/or SSH into it or plug it up and code it. They have a couple of these kits for $300 to $400. It’s one of the safe and simpler options.

There are also directions for the AVS sites which is under Alexa Voice Services, where you can go to the Github from there. There will give you directions using the Raspberry Pi.  If not that, there’s also the Slack chatroom. It is alexaslack.com. Travis Teague is the guy in charge in there.

JSJ 275: Zones in Node with Austin McDaniel

JSJ 275: Zones in Node with Austin McDaniel

The panel for this week on JavaScript Jabber is Cory House, Aimee Knight, and Charles Max Wood. They speak with special guest Austin McDaniel about Zones in Node. Tune in to learn more about this topic!

[00:01:11] Introduction to Austin

Austin has worked in JavaScript for the past ten years. He currently works in Angular development and is a panelist on Angular Air. He has spent most of his career doing work in front-end development but has recently begun working with back-end development. With his move to back-end work he has incorporated front-end ideas with Angular into a back-end concept.

[00:02:00] The Way it Works

NodeJS is an event loop. There is no way to scope the context of a call stack. So for example, Austin makes a Node request to a server and wants to track the life cycle of that Node request. Once deep in the scope, or deep in the code, it is not easy to get the unique id. Maybe he wants to get the user from Passport JS. Other languages – Python, Java – have a concept called thread local storage. They can associate context with the thread and throughout the life cycle of that request, he can retrieve that context.

There is a TC39 proposal for zones. A zone allows you to do what was just described. They can create new zones and associate data with them. Zones can also associate unique ids for requests and can associate the user so they can see who requested later in the stack. Zones also allow to scope and create a context. And then it allows scoping requests and capturing contacts all the way down.

[00:05:40] Zone Uses

One way Zone is being used is to capture stack traces, and associating unique ids with the requests. If there is an error, then Zone can capture a stack request and associate that back to the request that happened. Otherwise, the error would be vague.

Zones are a TC39 proposal. Because it is still a proposal people are unsure how they can use it. Zones are not a new concept. Austin first saw Zones being used back when Angular 2 was first conceived. If an event happened and they wanted to isolate a component and create a scope for it, they used Zones to do so. Not a huge fan of how it worked out (quirky). He used the same library that Angular uses in his backend. It is a specific implementation for Node. Monkey patches all of the functions and creates a scope and passes it down to your functions, which does a good job capturing the information.

[00:08:40] Is installing the library all you need to get this started?

Yes, go to npminstallzone.js and install the library. There is a middler function for kla. To fork the zone, typing zone.current. This takes the Zone you are in and creates a new isolated Zone for that fork. A name can then be created for the Zone so it can be associated back with a call stack and assigned properties. Later, any properties can be retrieved no matter what level you are at.

[00:09:50] So did you create the Zone library or did Google?

The Google team created the Zone library. It was introduced in 2014 with Angular 2. It is currently used in front-end development.

[00:10:12] Is the TC39 proposal based on the Zone library?

While Austin has a feeling that the TC39 proposal came out of the Zone library, he cannot say for sure.

[00:10:39] What stage is the proposal in right now?

Zone is in Stage Zero right now. Zone JS is the most popular version because of its forced adoption to Angular. He recommends people use the Angular version because it is the most tested as it has a high number of people using it for front-end development.

[00:11:50] Is there an easy way to copy the information from one thread to another?

Yes. The best way would probably be to manually copy the information. Forking it may also work.

[00:14:18] Is Stage Zero where someone is still looking to put it in or is it imminent?

Austin believes that since it is actually in a stage, it means it is going to happen eventually but could be wrong. He assumes that it is going to be similar to the version that is out now. Aimee read that Stage Zero is the implementation stage where developers are gathering input about the product. Austin says that this basically means, “Implementation may vary. Enter at your own risk.”

[00:16:21] If I’m using New Relic, is it using Zone JS under the hood?

Austin is unsure but there something like that has to be done if profiling is being used. There has to be a way that you insert yourself in between calls. Zone is doing that while providing context, but probably not using Zone JS. There is a similar implementation to tracing and inserting logging in between all calls and timeouts.

[00:17:22] What are the nuances? Why isn’t everybody doing this?

Zone is still new in the JavaScript world, meaning everyone has a ton of ideas about what should be done. It can be frustrating to work with Zone in front-end development because it has to be manually learned. But in terms of implementation, only trying to create a context. Austin recommends Zone if people want to create direct contacts. The exception would be 100 lines of Zone traces because they can get difficult.

Another issue Austin has is Node’s native basic weight. Weight hooks are still up in the air. The team is currently waiting on the Node JS community to provide additional information so that they can finish. Context can get lost sometimes if the wrong language is used. He is using Typescript and doesn’t have that problem because it is straightforward.

[00:21:44:] Does this affect your ability to test your software at all?

No, there have not been any issues with testing. One thing to accommodate for is if you are expecting certain contexts to be present you have to mock for those in the tests. After that happens, the tests should have no problems.

JSJ 338: It’s Supposed To Hurt, Get Outside of Your Comfort Zone to Master Your Craft with Christopher Buecheler

Panel:

Special Guests: Christopher Buecheler

In this episode, the panel talks with Christopher Buecheler who is an author, blogger, web developer, and founder of CloseBrace. The panel and Christopher talk about stepping outside of your comfort zone. With a technological world that is ever changing, it is important to always be learning within your field. Check out today’s episode to learn more!

Show Topics:

0:00 – Advertisement: KENDO UI

1:08 – Aimee: Our guest is Christopher Buecheler – tell us about yourself and what you do.

1:22 – Guest: I run a site and help mid-career developers. I put out a weekly newsletter, too.

2:01 – Aimee: It says that you are a fan of “getting comfortable being uncomfortable”?

2:15 – Guest: I am a self-taught developer, so that means I am scrambling to learn new things all the time. You are often faced with learning new things. When I learned React I was dumped into it. The pain and the difficulty are necessary in order to improve. If you aren’t having that experience then you aren’t learning as much as you could be.

3:26 – Aimee: I borrow lessons that I learned from ice-skating to programming.

3:49 – Guest: I started running a few years ago for better health. It was exhausting and miserable at the start and wondered why I was doing it. Now I run 5 times a week, and there is always a level of being uncomfortable, but now it’s apart of the run. It’s an interesting comparison to coding. It’s this idea of pushing through.

5:01 – Aimee: If you are comfortable you probably aren’t growing that much. In our industry you always have to be learning because things change so much!

5:25 – Guest: Yes, exactly. If you are not careful you can miss opportunities.

6:33 – Panel: You have some ideas about frameworks and libraries – one thing that I am always anxious about is being able to make sense of “what are some new trends that I should pay attention to?” I remember interviewing with someone saying: this mobile thing is just a fad. I remember thinking that she is going to miss this opportunity. I am worried that I am going to be THAT guy. How do you figure out what sort of things you should / shouldn’t pay attention to?

7:47 – Guest: It is a super exhausting thing to keep up with – I agree. For me, a lot of what I pay attention to is the technology that has the backing of a multi-million dollar company then that shows that technology isn’t going anywhere, anytime soon. The other thing I would look at is how ACTIVE is the community around it?

9:15 – Panel: Is there a strategic way to approach this? There is so many different directions that you can grow and push yourself within your career? Do you have any kinds of thoughts/tips on how you want your career to evolve?

10:00 – Guest: I am trying to always communicate better to my newsletter audience. Also, a good approach, too, is what are people hiring for? 

11:06 – Aimee: Again, I would say: focus on learning.

11:30 – Panel: And I agree with Aimee – “learn it and learn it well!”

12:01 – Panel: I want to ask Chris – what is CloseBrace?

12:17 – Guest: I founded it in November 2016, and started work on it back in 2013.

14:20 – Panel: It was filled with a bunch of buzz worthy words/title.

14:32 – Guest continues his thoughts/comments on CloseBrace.

16:54 – Panel: How is the growth going?

17:00 – Guest: It is growing very well. I put out a massive, massive tutorial course – I wouldn’t necessarily advice that people do this b/c it can be overwhelming. However, growth this year I have focused on marketing. I haven’t shared numbers or anything but it’s increased 500%, and I am happy about it.

18:05 – Panel: Are you keeping in-house?

18:13 – Guest: I think it would be cool to expand, but now it is in-house. I don’t want to borrow Egg Head’s setup. I would love to cover MORE topics, though.

19:05 – Panel: You are only one person.

19:08 – Guest: If I can get the site creating more revenue than I can hire someone to do video editing, etc.

19:35 – Panel: I think you are overthinking it.

19:45 – Guest.

19:47 – Advertisement – Sentry.io

20:47 – Guest.

21:30 – Aimee: There are SO many resources out there right now. Where do you think you fit into this landscape?

21:44 – The landscape is cluttered, but I feel that I am different b/c of my thoroughness. I don’t always explain line by line, but I do say how and why things work. I think also is my VOICE. Not my radio voice, but the tone and the approach you take with it.

23:25 – Panel: I was trying to copy folks in the beginning of my career. And at some point I realized that I needed to find my own style. It always came down to the reasons WHY I am different rather than the similarities. Like, Chris, you have these quick hits on CloseBrace, but some people might feel like they don’t have the time to get through ALL of your content, because it’s a lot. For me, that’s what I love about your content.

24:46 – Christopher: Yeah, it was intentional.

25:36 – Panel: Good for you.

25:49 – Guest: I am super device agnostic: Android, Mac, PC, etc. I have a lot of people from India that are more Microsoft-base.

26:28 – Aimee: I think Egghead is pretty good about this...do you cover testing at all with these things that you are doing? It’s good to do a “Hello World” but most of these sites don’t get into MORE complex pieces. I think that’s where you can get into trouble. It’s nice to have some boiler point testing, too.

27:18 – Guest answers Aimee’s question.

28:43 – Aimee: We work with a consultancy and I asked them to write tests for the things that we work with. That’s the value of the testing. It’s the code that comes out.

29:10 – Panel: Can you explain this to me. Why do I need to write tests? It’s always working (my code) so why do I have to write a test?

29:39 – Guest: When working with AWS I was writing...

31:01 – Aimee: My biggest thing is that I have seen enough that the people don’t value testing are in a very bad place, and the people that value testing are in a good place. It even comes back to the customers, because the code gets so hard that you end up repeatedly releasing bugs. Customers will stop paying their bills if this happens too often for them.

33:00 – Panel: Aimee / Chris do you have a preferred tool? I have done testing before, but not as much as I should be doing.

33:25 – Aimee: I like JEST and PUPPETEER.

33:58 – Guest: I like JEST, too.

34:20 – Aimee: Let’s go to PICKS!
