The most underrated feature of Elixir/Erlang is how damn stable throughput is. May not have the same straight line performance as some other languages, but throw more and more load at it, and it’ll still be chugging along with good response times long after other systems have fallen over. Preemptive multitasking is a superpower.

This article was pretty awesome. I still have no idea what most of this means, but the big number turned into a smaller one.

Been writing elixir for 6yrs. I have that natural curiosity toward other languages and frequently try them out. EVERY SINGLE TIME I end up thinking, "this is just so much simpler in Elixir." I try not to fanboy over any language since they are just tools but man Elixir/Erlang just works.

Re: "let it crash"--the Erlang joke at 5:11. "Let it crash" is a core tenant of Erlang design and programming. Instead of writing "defensive code", you let a process crash or "die", and have its supervisor or monitoring process restart it. That said, in actuality, you probably do not want it to crash and will likely write some defensive code, however, in the off chance something unexpected happens, having a supervisor process and that philosophy lends to a greater peace of mind. I guess the intended joke was that the major change from serverless to Elixir initially resulted in some crashing, so the saying "let it crash" fit the bill. Re: "fit the bill"--wait, stop recursion.

Elixir is the “One Man Army” language

the best article u read so far. i watch your videos for a month now. the other videos were good but this was the best. love it.❤

This guy deserves a bonus and a raise

Love this, been learning Elixir for the past week. Tried haskell in college and was told to look into Elixir by a class mate. Year later im checking it out and its enjoyable. Golang and Elixir are my languages of choice and im enjoy every second of it.

The interprocess communication in Erlang/Elixir is actually really cool. Once I understood it, it became my favorite model for this.

This is also a great showcase for indie/hobbyist dev - it just shows that even if you think your pet project will have an overnight success (an unlikely event), you still rarely ever need more than one or a few small servers. No need for “cloud scale” with thousands of “serverless” instances, when 1-3 tiny servers can handle ALL of it, and then some. The cloud is a lie (and I’m saying this after being a “cloud architect” for 7 years)

And the link was in fact not in the description

Serverless is really only for small to medium sized projects/companies. I think the strategy is generally to use serverless in order to spit out functional apps as soon as possible and then if any of the apps in particular blow up in popularity you would move that app to a self-managed infrastructure to maximize profit.

But serverless is very cheap.when you don't have users!

where is the link for the keyboard? I want to check it out

Serverless is a movement? Like bowel?

"That's a lot of shards" I'm laughing at this phrase. Once we tried to calculate how many shards we would need it came out as 300 just counting bandwidth, in the end SQS was an order of magnitude less expensive

I learned Elixir earlier this year and had to do a CRUD’s table for a small company cause they asked for it using Phoenix table. When the project was completed, I haven’t touched Elixir since, that was back in January. Sadly not as much demand for it (right now).

Every time that I hear serverless surprises me how much money they spend!!

Kinesis links are not in description

Stopped watching about half way to rewrite my services in Elixir to run on kubernetes. Will come back and watch the reminder after I deploy perfectly first time.

Honestly, I doubt this is a good use-case of BEAM which is designed for handling large number of connections concurrently in IO bound scenarios. This problem looks more like CPU bound because the server doesn't need to keep connections while waiting for external API or something. If the requests from clients take time and cause large number of concurrent connections, then we can just put nginx or something to deal with the bloated connections.

never written elixir before so i can only assume what the code shown @10:56 means. im gonna apply the knowledge i have of languages in general but since this is a specific language with its own nuances im most def gonna be wrong about some things. im guessing defmodule is a keyword & as it implies it is used to define a module, which is essentially a namespace. now the syntax on the following lines that start with @ are just that; identifiers from what im guessing. so the first line would be an identifier for a struct/class/interface/namespace, since im unsure what Storage actually is or if elixir even has classes/structs/interfaces. the second would be an identifier for the string literal " " and the third identifier would be assigned to the returned value of the get_env function located in the Application namespace/module or, from a c#/java perspective Application would be a class and get_env would be a non void public static method. unsure about the arguments it takes in and the syntax associated with. then on the next line the def keyword is used to define a function which is exactly like ruby & python, following that would be the identifier of the function & its single argument, "do" would obviously indicate the begining block of the func. then the body of this function would be the actual procedure that this function does. Seems to me that another function is being invoked from the File module; the write function. Which makes sense if File is infact a module. You would want some kind of write functionality. it takes in the value of @log_file as the first arg which im assuming is a path to a file, and im assuming the result of concatenating its actual argument assigned to the identifier "msg" with the string literal " " would be the second argument. my reason behind guessing so despite not knowing what the token "" means is because it looks to me like an operator & the right operand is defined a string. so if im right, the code is actually readable compared to most typescript (especially generics) that u will find out in the wild & especially on yt.

Cory O’Daniel is a gangster. Stick with him, y’all.

Deep article and good commentary.

Why not making an express server and start off some child processes or clusters for processing and wait for a batch to be finished before sending it to this mysterious kinesis, if your server can handle the load?

Elixir? I hardly know her.

Im surprised elixir isnt more popular, I fn love it

I see elixir, I like

When you look at the description looking for the links for the keyboard and find nothing...

Dang, this article is 5 years old.

🎉🍾🎊 elixir mentioned 🎊🍾🎉

20:52 I think "contrarianism" is a good product of critical thinking (to an extent). We know people are fallible and can get swept up in hype. When there's no counternarrative that's pointing out the downsides or nuance of a situation or thing, its generally a good thing to give some air to the skeptic so they can scrutinize the narrative. This isn't to say that things can't have a huge amount of pros and very little (relevant) cons, or that the skeptic themselves are going to be constructive; just that it's good practice to keep an open mind to nuanced views. "There's a time and place for everything," and that is never all the time and everywhere. The higher the stakes, the better it may be to seek said nuance out on your own or to play "Devil's advocate" in efforts to stress test an idea and play it out to its logical ends. PS: That said, sounds like TheFightagen just wants to throw a few "Oh really?"s. Edit: Better -agen.

the constant beef with elixir is so entertaining

they have users?

Prime's skepticism about serverless hype, lies, deception and the need to go along is better placed with the Typescript crowd.

another episode of: tech choices that you will never see happen in an enterprise/big company

Someone broke your keyboard in half

11:11 That is evil annotations black magic.

Loud ass Iago from Aladdin sounding mf, waking me up when I fall asleep to youtube.

Finally - elixir

5m/h request, is this netflix ?

I am learning elixir it's fun

... and now there is FLAME ... Serverless PLUS Elixir functions ....

I really like that elixir juice.

Remember back in the day when developers threw their code over the fence and let the sysadmin handle deployments and infrastructure, and then they invented "devops" so developers became responsible for the infrastructure their code ran on, and then eventually nobody specialized in anything anymore, and then infrastructure became so complex that it became impossible to setup shitty infrastructure to run shitty code as fast as we deployed quality code on quality infrastructure, and now developers are throwing code over the fence to "devops" who spend most of their time trying to keep the costs down and wondering why nothing is stable anymore? Yeah, good times.

Upboated for the trippy elixir

Why not go? well I came to elixir from go and rust...Elixir is simply pure joy compared to others

Why not client-side JSON schema validation? It would save you from using a Lambda.

nothing against the point of the author, BUT, i ran into the same issue wtih AWS api gateway costs and found i had to convert from REST to their lower tier HTTPS and it cuts the API costs in half.

Collecting metrics on your metrics is the circle of sadness.

Do they even need K8?

Love Elixir

People are getting over reliant on cloud based abstractions.

Wow that is some quite low hardware load

'' is string concatenation in Elixir. Most of the functional langs have something different than (ehm retarded) C-like syntax '+' .. OCaml use '^', Haskell '++'

The whole thing can probably be handled by 20 hosts on Hertzner with haproxy, for $1000/mo, completely over-provisioned. Or (if you really need to) in AWS for somewhat more. But tell me more how KISS your setup is, with AWS, Elixir, Kinesis, Go, Node, k8s, and whatever else was utilized there.

>2018 Now suddenly everything made sense.

Kinesis alone is a financial black-hole...

Complains about cost and moves to K8s hahaha good one

It is hilarious how passionately ThePrimeagen hates Elixir.

Elixir has little in common with Ruby, only surface syntax but in Elixir it means things that are very different to Ruby's In Ruby a module is define between the keywords "module" & "end" and it is just a bag of definitions for ruby, the only way you have to ship it is as a file and supports no versioning. In Erlang(or Elixir) a module is a distribution unit of code, is the minimum code the beam loads and it is binary and it is versioned and the BEAM (Erlang's VM) allows to load to different versions of the same module, and if you use correctly the supervision tree it comes with an automatic mechanism to update the module in all the running instances and if you have processes of the old version still doing job, it waits until they are done to kill them and replace them. So Ruby & Elixir are way to different.

raw dog me and append me 😂😂😂🎉

As an Elixir bro, I watched this one live and thought it was never gonna get uploaded bc the article sucked :( It was just "serverless bad" for 20 minutes with not enough "elixir is goated" to compensate 😔I hope we'll see more elixir content soon though :)

I like the tooling and fundamental concepts of elixir, I just can’t get over the Ruby-ness.

TLDR. They change it, because people finally realise ok, we don't need that k8s / terraform crap.

no funny comment this time, just wanted to say hello :3

W elixir

I smell bs, either at a management or engineering level. If and only if the service is running optimally then the aforementioned 12k bill shouldn't be an issue if the service is actually providing value to the business to offset it's cost. Either the engineering is bs or management pricing the service to customers is bs.

cloud bad

Why is Erlang getting no love 😢

Serverless means peer-to-peer, not what you think it means.

Which one to chose Elixir or Go for chat app? and for e commerce?

Elixir getting types soon sounds interesting. I did some programs on it and it was fun, but I guess I gravitate towards C syntax. (GO). Still, cool community that's hardcore in love with the language. Scales well (like Go), and has cool web stuff (like Phoenix). Also part of the "NOT JS" Crew. lmao.

isnt this an old ass video
