Potluck × Is TypeScript Fancy Duct Tape × Back Pain × Cloud Service Rate Limits

he obviously is so dialed. And anytime he's eating something, it's like, oh, he cares about literally everything because he's an athlete. And us as developers, we're athletes. No. We're we're not athletes, but are how many?

rid where Scott talked about stretching. And it's funny to me. I kind of see it as I'm gonna relate this to skateboarding, cast it or do a type guard. And I I sometimes run into this as well where, like,

You you do have to take care of your your mind and body as well. How you do that, I will ask Scott because that's kinda his route here.

Kind of scary to me

like, look go look at what Nigel Houston does. You know? Rid He has so much regimen.

rid by foot, and I stretch occasionally. Is that too little? Thanks. Hope you have an amazing day. Yeah. This is

Mathletes. You gotta think about, like, okay. If I wanna be the best dev I can be, like,

something that is

rid. It would be kind of scary to to do that type of thing, and I am kind of getting more into stretching. I know we did a show probably 2 years ago

a whole whopping 2 hours before bed. Like, that is my my Sunday Sunday routine, term. And not only that, it'll it looks wild. When you go out in public and you see people, their necks are permanently stuck forward, You can tell. Like, that guy's addicted to his phone,

once the kids are in bed, you know, 7:38, work on your ergonomics. You don't have to, like, Fall out and do ergonomic everything.

My successful workday and successful workweek always comes in because every Sunday evening,

the kids are down, rid I can play video games That that head forward posture from looking at your phone or shoving your face near your computer is a rid. Real problem long

your time for myself, So After every battle, we would get Mickey's, which was a 40, and, celebrate with Mickey's. That was our favorite.

rid. It was it was really hard to get back into it. I was telling my wife, and she's like, have you never had that before, rid. Somebody wrote something, and it called itself and spun up a $6,000 super interesting.

I was I was in total relaxation mode, so I think it was a little hard to to get back up and running. But luckily, we just had a really good interview with rid. Andres, rid. It's the opposite of that is that there's cousins everywhere to play with, and there's parents everywhere to watch the kids. And Yo. What? What? How about rid. Drinking beer and Yeah. Ripping on the ATV. You know? Yeah. That that's a lot more fun. And then we just had a really good

where, my whole extended family came up to the cottage. And just turn it off. Right? is rid Certainly wouldn't want to go back to writing just regular JavaScript even if you're just using it for the at the very least, if you're using it for the autocomplete, And then at at that point, if it goes more than 3, something's wrong. You know? You gotta you gotta take a look. You talk about containers or what? Rid In my render yeah. My render containers or digital ocean droplets or whatever. They can scale up. So that's that's certainly one way to do it. Rid. I think the issue here is that, 15 years ago, skateboarding was just a bunch of stoners going around. But now if you look at Who the top skaters are these days?

programming?

where, like, after a vacation,

It was like the the kids fighting in the pool or doing anything like that was, like, just both of us would just look at each other and be like, oh my gosh. This is just, You know? But it could be much worse. So, you know, obviously, we're just very stressed out, with life stuff and, you know, ready ready for that beach time.

and and Thrice.

Rid Life's a lot. We just I just got off a week of vacation rid Filter?

I'm gonna be on the beach next week, And I think my brain needs it. I I've just feel it very by all these cloud services not providing an option to Shut off services when the spending limit is reached.

Doing good. Feeling feeling ready to go.

It's I just this morning, I was just like, why don't more companies have that? Like, you could just turn it on. Like, OpenAI does this beautifully. Rid. You can do you can set a soft limit and a hard limit. Meaning, email me when I go over a $100 and turn the thing off All kinds of really great stuff. My name is Wes Bos. I'm a developer from Canada. With me, as always, is mister Scott Talinski.

at

And, like, even, like, yesterday, we hung out Yeah. You know what? I, you

a local pool with the kids. And and Courtney and I, I think, just felt so tapped. We we felt so more so than

usually at the end of a vacation, I'm just like, ah, like, this is nice to get back to the swing of things. Rid Probably.

is TypeScript

rid an array of strings.

you're not gonna have rid Spend that time finding those bugs. The compiler is going to find them for you, or even better yet, your editor is just gonna put a little squiggly in there while you're podcast recording Monday is like, alright. It's Monday. We finished recording the podcast. I'm gonna work on my to do list. I'm gonna work on my email,

man, is it worth it? It's worth it. And you know what? I do have to feel I feel like it is a little bit of just duct tape, but maybe like the the next level up of duct tape. It's not like It's not quite like a, a foundation of a house and it's not quite duct tape. It's a little bit in between, you know. A strong wind can blow it over, but it definitely is going to rid. Save your bacon for

rid array. So he has he has a type curly, wavy, or straight, but then he also has an array, curly, wavy, or straight, which is simply just, so you can't spend up $6,000 You don't wanna go back to work? Mhmm. And I was like,

And then, therefore, But is TypeScript just duct tape? Is it just kind of, you know, saving you a little bit these consequences? Yeah. It is. It's gonna save you those easy bugs. It's gonna save you those easy bugs that you might have to find yourself otherwise.

if you change code, here's some hints as to the consequences, what they may be. I have prepared an example I have a long history with stretching. I grew up my dad was a gymnast,

rid. It's it's not a impenetrable system

absolutely everything, especially once you start getting into these types of things. Rid In your case, I would write a custom type guard to make sure it's in there. And also I would They're they're athletes. Yeah. Like, they have

hints. So I think what they're saying here is, like,

rid Where I can see Exactly. Yeah. I the amount of little edge case y things, especially, like, a lot of my Initial hate of TypeScript

It's not a I, overwhelmed and overworked.

the way way this question is put Host is that, like, that's a bad thing. Right? Like, oh, it's a it's a bad thing that TypeScript won't save us from every potential situation, is simply that I'm not pinching my shoulder blades together.

You have to

just a bunch of fancy duct tape? And I think that's really what you do need to look at it as. And I wouldn't necessarily

generate I would not duplicate the union and the array of possible values.

rid. But it's certainly not going to catch And in there, he's checking if the inputted value is both a string

And they say basically, like, hey, because I've been having some some some weird I I messed up my rotator cuff, so I've been going in for that. So But she was telling me that, like, part of my posture issues

Curly, wavier, straight.

rid Writing so you could say, oh, yeah. I forgot to do x, y, and z or I still need to do this or this might have a possibility of potentially breaking.

And I personally,

that if you follow TypeScript, your code will be perfect every single time. And also even if your code is perfect, That doesn't mean TypeScript's gonna be happy 100% of the time. It's it's definitely People are you gonna want to work on on this vacation? Not as, like, a negative. She just wanted to know if I had to work. You know, we have,

You know, remember we were, like, using filter. We had 2 different types, and you filter for a specific type of 1,

Unfortunately, yeah, that's that's the case in in some use cases. So is it a bunch of duct tape? I don't I don't think it's I wouldn't go that far,

even though the code works fine.

But also we have to do extra things to appease TypeScript sometimes

rid One, the having to write code to a piece TypeScript is a trade off you make. You use TypeScript. You're gonna have to go out of your way. You're gonna have to take maybe the long way sometimes We just had a really exciting interview about email, and it got me super excited to get it. Surprisingly.

And that's a union, so a list of possible options, curly, wavy, or straight.

rid I look into a library and go, oh, how are they ensuring that it is of of a specific type? And you look into it, and they're just using as. You know? Totally. Yes. Exactly. Me. You know? And, Almost never at home. But the fact that you can dial in the height

And I think TypeScript is getting mad here because it's a possibility that that

textures.

rid. TypeScript doesn't run at runtime, meaning that it doesn't know the value of the

actually I don't know what what it is. It's it's Monday morning, and 2 Monday mornings are just very tough. I I don't know what's been going on. The kids have a lot of stuff.

Rid. And return from that is it says it's just a string, but it should be returning a texture. Right?

I'm learning TypeScript, but so far I have noticed that Other than auto completions, it is pretty much saying good lies to ourselves and having easy code change

Rid I would just create an array of the values and then generate a exactly how I want it. Because right now, I have my chair a little bit higher than I would like,

and say, there's no possible situation I don't have any back pain or anything like that. But a type directly from that. So, I don't know, some sometimes you see people saying this, but rid And and TypeScript doesn't realize that you filtered it at that point. Somebody messaged me and said TypeScript 5.2 fixes that, which is really nice. So I think, yeah, there's there's a lot of like annoying little

You're stopping

from from, like, crashing your application. Yeah. Totally. Yeah. Next question from Christian.

You're making me add you're you're I'm probably doubling

a potential weird edge case

Mhmm. Which is a little bit of a bummer. But in reality, a lot of the cases are you're rid.

Could you share with us how you go years into rid. Programming without back pain. I'm coding as much as I can

from being

a lot of time, you know.

was just me not realizing, oh, that could be a possible bug. Rid. And as much as you think My job is good. Never it's never gonna happen.

The amount of code I have to write for this function just to satisfy TypeScript

I don't know, a long time because it takes Actual muscular training for your body to adjust.

So so I'm I'm a stretcher. I I like that stuff a lot. But, you know, more importantly to me than even stretching or or Mobility stuff is Yeah. You're, like, you know, I try to sit up straight. But a physical therapist that I have, Rid. For some like Firebase, you can program a serverless function which shuts off the service, but that's complicated and error prone. Yeah. Jeez.

Posture is one of those things

To you is to 1, be cognizant about your posture.

you know, I even have it too. I mean, it's not like bad because I'm constantly thinking about it. One of the the big Tips that I learned very recently from physical therapy rid that won't we if you have back pain that's persistent and long lasting, it it can be a heck of a thing To fix, to get rid of, especially the longer you go without fixing it. So to fix part of this posture issue, especially shoulders based, is that when people often are told To sit up straight. Like, one of the first things they do. Right? And this is this is gonna be really good for anybody who's sitting all day long. You get told to sit up straight. And what do you what's, like, the first thing you do? You, like, pull your shoulders back and, like, sit up. Right? Nice. Yeah. And one last thing, you're talking about the skateboarders.

And one thing that I've begun to really notice this awful posture grab and pull and hold. Because those static stretches where you're grabbing and rid

And it's not like I'm not thinking about the tops of my shoulders. Like, typically, when you think about pulling your shoulders back, you're thinking about, like, actually pulling your shoulders back. But it's much more subtle than that where I'm thinking about

that rid just to make TypeScript happy, you know. Oh, you have to you have to take this little detour here just to make TypeScript. I'm fine with it. That's the price of admission.

in my world about back pain.

So he,

in the world,

fix it, and then move on with your day, and then think about it. It's a it's it's which you don't get much of these days. So, like, it's great. Yeah. I love that. All right. Let's get into the questions here.

you know, very early on in life. Like, if we're watching TV, my dad was sitting on the floor stretching. So, like, I grew up with that kind of model. So I I'm the I totally inherited that. I'm stretching

So Is TypeScript my solution

all the time. I one of the reasons I got a standing desk is so I could stretch at my desk. I I I'll put my foot up on the desk. I was kinda largely known in in some of our offices as the guy who will Occasionally, sit on the floor and stretch at work.

One one thing, the best The best dynamic stretch you can do in the morning to help with your back is to do you put your your arms up at, like, You know, 40 or at 90 degree angles. And you just do really I don't know I've ever had a 40 in my life. Oh, man. That was our. They're they're really super cheap.

It's a long term thing. You gotta just think about and improve. But either way, think that I'm gonna I'm gonna start an athletic thing, so I'm gonna stretch my legs. I'm gonna put my leg out, and I'm gonna just stretch it like you did. That's actually wrong. You should be where even I know the implementation is 100% right. So The Dackel has included a Stackblitz example here of basically an example where they know the implementation It is, like, a different world, and you can already see the level changing in, like, one year. It's it's been drastic. Yeah. It's it's wild. They went from old English forties to smoothies real quick. Yeah. Right. That's it, through the motion is going to help build muscle. It's gonna help Wake, you know, warm your body up a little bit and just,

where their head is forward and their shoulders are slouched forward. Everybody has this, like, forward head posture,

like, maybe even 30 seconds later sometimes you're out of that posture. And just

And

you're not going to be good at it for,

straight up posture lately for me has been a big topic not just computer programmers, but in the world, every person

Has

Rid. Do you remember that where it's like every day because of the session, but also start feeling some back pain. I am going to the gym, rid How many big companies Enough detail. Yeah. Yeah. Alright.

because I don't stand all that often, but I just want to be able to set it I was very happy when I found that pillow that actually worked for me.

Like, we got, like, one of those Tempur Pedic mattresses. The, like, Yeah. The heavy phone that you sink into, and I got a they they pitched me on this really thin pillow, and I'm like, I don't know, man. I'm like the type of guy who's got, like, rid pillows are, like, a little bit more there, and they're like, no. That's messing up your neck. You want a really thin pillow for these reasons.

next year, You know, just as a host for a long time now. Although we are moving to Vercel for syntax stuff. Right? So I'm gonna have to get used to the Vercel stuff. But Saving us is the the root of this question. Does TypeScript save our bacon or is it really just a system in place to potentially Mhmm. So if you fix your posture 1 minute, like, different types of And I went to the thin pillow, and I have not looked back. Rid I'm very into it. So yeah. I don't know.

and I have to do that because of how high the legs are on my desk. Right? Yeah. So it would be really nice to do that. And the other thing I'm talking about is

basically, you lay on it and it, like, supports the back of your neck. And, like, rid. That was such a big benefit because I would often wake up with, like, a really sore neck or, like, a headache.

And again, I came to the cottage. I don't have that pillow here, and I rid. Noticed that immediately when I woke up.

If you wanna see that active right now, Wes, the breakdancers, now that they're going to be in the Olympics

There's so much there. Yeah. There's so much for like, it's rid It's such a personal thing. Like, that's my problem is when I have too thin of a pillow,

So I was, like, looking into it. I was like, oh, maybe I should buy 1 for for here or just bring it with me. But everybody's talking about these cube Pillows right now? Yeah. I see them. Like a hard square?

adjustable Legs for it. Yeah. Legs for it. It doesn't have to be the, like, rid The standing ones

they have rid. From in, like, 2 years. Now the Olympic team is training at Olympic facilities, and it's like

that was, like, shaped to your head.

Mhmm. I think I wanna try that. It seems so cool.

in breaking had an official forty. Our forties was Mickey's.

rid. About a year or 2 years ago, I I sick picked a a pillow

Or maximum amount each month, but I don't want a surprise $10,000 legitimately. In fact, our our our Crew. Wes, you laugh, but our crew I don't even know know if you can buy that in Canada. Malt liquor. Just big old big old beer. That's not good. It's not good beer, but when you're in college and they're, like, $4 or something and that's all you need, it's rid. Good. Yeah. Alright. Slightly annoyed in Michigan. Hey, guys. I'm slightly annoyed

All I need is to all I need is a toggle in the settings UI. This really sucks

this might be a use case in which I am the type of person where, like, You know, before our vacation, Courtney was like, be cool to yourself, be kind to yourself,

if if it really calls for it. But, like, a straight up node server the I mean, maybe, I guess, for serverless functions, that's that's one thing. But, like, maybe you just need a straight up node server to host on. And, like render, rid. I have a a fixed price amount node server that I can put on auto scaling, but I can set auto scaling thresholds rid to say, hey. Only auto scale up to this dollar amount,

rid. Has always The the the kids will set her off more, you know, in terms of, like Yeah. Really, you know, being able to get to her. But, like,

if I add an endless loop. What's your opinion on this topic? Cheers, and keep up the great work. I Totally agree. And, honestly, I'm shocked that those things don't exist because I've been on render, is 100% correct, But TypeScript is not happy.

for a fixed price

I mean, do you need distance in terms of, like, how far you can go and stuff. But this dynamic stretching where you're where you're moving really invest time into getting your posture worked at. And and the middle of my shoulder blades and just pinching them together. And I'm not thinking about my shoulders long. My shoulders are loose. And that to me, that has unlocked every single little posture issue that I have. If I'm feeling any type of back pain, all I think about Is pinch those shoulder blades together in a way, and it just fixes everything.

worked pretty well for me in these scenarios, so maybe that's really what you need. Yeah. You can set, like, I have mine to auto scale that weekly routine there to chill me out on Sundays to get ready for the week and be like, alright. This is like Help us along.

rid. From 1 to, I think, 3.

bill

Best you can do with most Netlify, Vercel, etcetera, is to set a billing alert via email.

for hobby developers and toy projects. I'm fine with paying a fixed because he's just shoving shoving his head forward. But it's gonna cause you a lot of a lot of shoulder pain. It's gonna cause you back pain. And as somebody who has back pain, like, that stuff does not go away. I I back pain from, like, spinning on my head and stuff. It's a little bit different. But,

ready to get back into it. But

the night before on Sunday night? Yeah. Like, on Sunday nights, it's, like, guaranteed Seems like it that would work. I got a pillow matched to our mattress.

I I think it's just the end of the day. It's, like, just the, the dread of going back to work. And it's not like she hates her job or anything. I I think it's just like those transitionary periods From going from not working to working your way, much more difficult. Where I'm like usually, I'm like ready to get back into it, you know? Totally. Yeah. Some rid I don't I don't get that at all, which is the best because I would get that for school. I remember being in school and being, like, Sunday night and just having that, like, pit. Like, I don't wanna go back to school.

Especially early on in that job. So she was like, I understand if you gotta get, you know, stuff done or whatever. I was like, you know what? I'm gonna I'm gonna take this time, but I am the type of person too where, like, When my vacation's done, I'm usually, like,

You know, to some context, we have an a new job. I have a new job. And, like, having a new job, you always want to, you know, show out and and do your best work, Consequences, instilled stretching, like, last year, they were not training at Olymp they were training in some guy's backyard. And this year, they're training in Olympic facilities.

she's gonna be more anxious. She's not going to sleep well.

I don't know about you, but, like, Courtney gets the Sunday scaries really bad. Do you have you ever heard that term before? Yeah. I've been hearing that a lot lately. Where is that where you just get that, like, gut a tool to help rather than, you know, an all knowing god.

working for myself is that I'm luckily,

sometimes my mind starts cooking on stuff the night before Sunday night, rid. And I have to bring out the to do list and do a little brain dump.

Otherwise, I start chewing on what needs to be done because I go, oh, my gosh. What a busy week, Caitlyn. Like, I've rid I got so much going on this week. I'm I'm feeling a little bit stressed out, but then I'll I'll bring out my to do list and try to just dump

rid Is the best. Doing this podcast is the best because, like, I I don't get that at all. If anything, rid. Don't ever want their website to go down, you know? Rid. And they are working on

and I'm going to get set up essentially for the rest of the week.

And,

Rid you know, my Sunday routine of you know, this is I think it's a nice little detour conversation, but my Sunday routine Yeah. Has always been a big part of my successful workday.

And the one thing I have a Herman Miller Aaron at both rid Locations at home and at the cottage. And I I don't have the rid Could change. Right? And you have you would have to put a custom type guard in here instead of just using straight up includes. I actually talked about something similar to this where

at home is so good. So now I'm thinking I have this beautiful maple slab desk And I'm thinking, like, maybe I should buy a set of,

standing desk here, which I don't stand, bill. And props to them because they took care of it right away.

Rid Go back and listen to the episode on on stretching because it's Why do cloud services not have cutoffs

Actually, I have 2 more things to add here is rid So I'm at a cottage right now where I have my my cottage office.

perfectly Really? It's like Yeah. They don't have that. Canada.

You're listening to Syntax, the podcast with the tastiest web development treats out there. Strap yourself in and get ready. Here is Scott Talinski and Wes Bos.

Welcome to Syntax. Today, we've got potluck for you. Rid You're bringing the questions. We bring the answers. We got some really good questions. Is TypeScript just a bunch of fancy duct tape? How do you program without back pain?

light twists I'm gonna Here I am. I'm cracking all over the place. That wakes up your whole spine. It'll get your your back muscles warmed up and moving, And those are the types of stretches that you'll want to do and I'm free to play video games for that time. And, for something for some reason about that, it it like, just having that

doing dynamic squats where you're standing up and getting up. You should be doing, But Yeah. Posture at the very least is a big one. You know, stretching.

That's a mistake you'll often see in athletics.

and holding. They're good for, like, building, like, it it's a much better warm up.

But, yeah, I could go on all day about this stuff. We could do it with the show.

with your shoulders up, Just light twists where you keep your lower body in the same spot and your upper body twists. Just mobilizing your spine. And, Wes, ideally, you want to move your head as well. I'm just having Oh. Yeah.

movements To warm your body up rather than static stretches. Static stretches are for the end after your athletics.

end end

length of, like, rid rid Sort it by anxiety, and then I feel a lot better. So I'm just really glad I don't get that. I like to do that, and and, typically, I'd like to do that. Look. What When I will do that is, like, right after we finish recording the podcast. Like, my post

How you doing today, Scott? Hey.

by accident?

customers who

like, specifically Vercel, they had a couple issues where Rid The example that he gave here is he has a function that takes in a string and returns a texture. A texture is curly, wavy, or straight.

rid Serverless functions, things here where any dev can look at that code rid And it is in a that this would be a string, it's going to be one of those union values there. And in order to make this work, I'm all creaked up. So I need, like, a a more of a significant pillow, but not too much. And it's just a

Rid. So you got to wonder, like, I follow him on Instagram. I never see the guy take a sip of a drink. He's at parties all day long. I don't know if that he probably drinks, but

Another thing I think about a lot is So in order to make this, like, you kind of wish that it would realize, okay, well, the only possible options in this array are

rid. I I often wonder, like, why don't they

Wow. My project got super popular, which can happen, but sometimes it's when, like, you accidentally write a loop and bankrupt yourself, everything into my to do list,

rid. From that type of thing, it's kind of tricky for them because they have lots of list of possible, if you don't want that, you could just

just pay the bill? You know? Oh, shoot. That thing spun up an extra $6 worth of

When I go to $300. And It's a bit of a stretch. We're athletes. Yeah.

And and then you have the hobbyists where they say, I don't ever want to pay more than x, y, and z. So And I think the issue with this is that Go for it. You got the first one. 1st question from Dago. Dago says,

they said they were working on recursion detection, which I think is what happens a lot with this type of thing. It's not necessarily,

And he I don't know. He got me really excited about email, and I think that rid Kick me kick me back into it.
