What makes this video so good is the tonal quality of the narrator and its pace. Easy listening is great for absorption as opposed to many other videos wherein the presenter is in a great hurry with everything where as a result things can get murky. That is not the case here. Thanks Tensor - I look forward to discovering your further contributions to enlightenment!!

Thats surprising, since I do tend to "rush" a bit in these videos. At least that is how they've been edited.

Functional progrmming just feels right. Paired with Elixirs clean syntax it is an absolute joy. Lots of cool tech is evolving around Elixir like Horde a distributed Supervisor and Registry.

@TensorProgramming 5 жыл бұрын

Yeah, Hordes is pretty cool. So is phoenix LiveView and Whistle but even among all of that we've got the full OTP and the BEAM which are amazing pieces of technology. Ill be covering as much as I can in this series in so far as OTP and Elixir goes. And of course, this includes Elixir's brand of Functional programming which uses pipes rather then function composition.

@@TensorProgramming oh I've seen quite few of comparison videos based between them both. Seems to me that for scalable microservice architecture, concurrent connections and parallel processes they do battle it out for stack market share. I am a new dev so eitherway thought it might be interesting to here a comparison video on which to choose over one another and for what reasons.

Fantastic introduction! Slight error at 28:50 when you mention string sigils and interpolation. Using “~s()” you do get interpolation, but if you use “~S()”, with a capital S, you do not get interpolation.

Sure, there is a distinction there. There are also a ton of sigils I didn't cover though.

This was a very well done and informative video, I'm looking forward to the rest of the series. As someone who is a junior web developer using Python/Django, would learning elixer be beneficial? Is it feasible that if I put in the time with it there are career prospects for me? Please keep in mind I've only been working in development 2.5 years. Thanks!

@TensorProgramming 4 жыл бұрын

There is nothing wrong with learning something new even if you don't plan on using it in your job. You can always try to convince management to use Phoenix if you think that it fits the use-case a bit better than Django. And even if that never happens, learning Elixir will teach you to be a better developer overall.

My original comment wasn't to say that its not a viable option for work, its just rare compared to many other languages but the shops that do use elixir really need elixir devs because they are also somewhat rare. Have fun, hope you do well on this Gig.

Hi, would it be possible to create a tutorial on how to set up a similar environment to what you have? I've been trying for a couple hours now, and without success. Most I managed to achieve is install Emacs and open it to some read-only text file.

@TensorProgramming 5 жыл бұрын

For Emacs I am using a setup called Spacemacs. Its pretty self explanatory and they've got a ton of documentation on setting things up. www.spacemacs.org/ They use what are called Layers which installs a set of plugins for whatever it is that you want to do. if you put in say Elixir, it will install a bunch of extensions that work with elixir; such as the ones you see in this video. I use Emacs a lot but VSCode works just as well for working with Elixir too and you will see that I use it more in the future videos. The main reason I used Emacs in this video is because I wanted a more intelligible Repl for Windows. On the Terminal you don't get auto completion or syntax highlighting.

This is weird on Elixir. Why does it have to appear the code x = 10 twice, but it doesn't print the number 10 directly when we type x = 10 for the first time ? x = 10 x = 10 10 But not x = 10 10.

@TensorProgramming 8 ай бұрын

Its showing the input and the output. The first line is just what I typed where as the 2nd line is the input in the repl and the 3rd line is the output. If you did this in the CLI instead of emacs, it would just show one line for input and one for output.

@chusto33 3 жыл бұрын

just a quetion about emacs, do you have any video tutorial where I can follow the steps on how to configure elixir? thanks Tensor

@TensorProgramming 3 жыл бұрын

No, I did not make an Emacs tutorial. However, in this video and in general, I use the spacemacs emacs distribution which is very easy to setup. It has "layers" which allow you to enable a bunch of emacs packages for each given language. So if you enable the Elixir layer, it will setup basically everything you saw in this video. You can find the information here: www.spacemacs.org/ and you can find information on the different layers here: www.spacemacs.org/layers/LAYERS.html

Why do you call a tilde (~) an "enye"??

@TensorProgramming 2 жыл бұрын

I know its called a Tilde; I just don't often use that word and when I get a "cache miss" in my memory, I default to my first exposure to the character; aka the enye in spanish which is the N with the tilde above it. Its a part of my dyslexia (I am guessing) that I tend to make associations like this with different words and characters and end up using them over their proper names.

I am in my first year of graduation, and thinking to opt for a future proof language to choose for a carrier, I have my background in cpp but thinking of also giving a shot to emerging language, what is your take on it, your recommendations for example between, zig,rust, elixir etc :)

@TensorProgramming Жыл бұрын

You can't really go wrong with any of those apart from maybe zig (at least as far as work goes). Zig just hasn't seen much adoption yet, so I wouldn't expect to find any stable position with it in the next 5 years or so (its not a bad language, its just very new). Elixir is starting to ramp up more in terms of adoption due to it use in ML and Rust is gaining traction as it has for the past 3-4 years. Even if you don't find a position with any of these languages out of the gate, doesn't mean that there isn't any value in learning them. When you climb far enough up the totem pole as a dev, you can pick whatever technology you want assuming you can make a good argument. Each of these languages will teach you a new paradigm and give you yet another tool in your programming toolbelt. Hell, I still write lisp, APL and prolog sometimes because they are very good tools for what they do.

Maybe a more beginner oriented question - any ideas for a "weekend project" that one could build with elixir? I don't really have a use case for the language, yet I am strangely drawn to it :D

@TensorProgramming 4 жыл бұрын

While Elixir does have a very niche usecase, you can use it for things outside of that usecase. You can build Neural networks and other machine learning projects, building GUI apps, write systems and make embedded projects. There are the obvious choices for a weekend project, building a full Twitter/KZbin/Facebook/Instagram clone etc or you could sit down and building a CLI or a Programming language. Its really up to you and what you are interested in doing.

@TensorProgramming 4 жыл бұрын

Depends on the platform that you are on. If you are on windows you can get it from the gnu emacs site and just unzip the zip file and then run it. You can also use command line tools like scoop and chocolatey to get it. On Linux and Mac you use their respective package managers to get emacs. And then for spacemacs, its a matter of cloning the github repo into the emacs folder.

How does Elixir convert from 0xFF into 255 and 3.0e-2 into 0.03 ?

@TensorProgramming 8 ай бұрын

It just has to do with the basic conversion that happens inside of the repl for the sake of simplicity. In reality, all of these values have equivalencies as far as data goes.
