Hey Derek, which of the following would you recommend as an utility language or just a good addition to my resume ? (Already familiar with Java, C#, Python, JS) Lua Lisp Julia
Derek Banas (2 days ago)
Based on that list Julia

Hi Exodus, I miss making them :( I ordered a new Mac, but Apple is terribly slow. They say I can't get it till the 20th! I would get a Windows machine if I wasn't so heavily invested in Apple.

@Derek Banas  thanks for all of your helpful effort ... Can you please make some video tutorial in advance how make a website from scratch as full stack. I read all of your previous tutorial but i can't join the knowledge and make a e-commerce website with review section together... i think a new tutorial could help a lot to how link database web services and html css bootstrap together and make a web site with storing data in database (as Review of selling item for example) ... if you can use mongodb as database to store no sql data would be great... lack of example to how link your previous tutorial to create website from scratch to the publishing and release mode is very sensible

I'm learning Julia and it has slower speed and different scope rules outside of functions, therefore I use: function main() # move everything outside a function into here end main()
Rikrish Shrestha (13 days ago)
Mr. Derek, I watched your 'how to learn everything- anki tutorial' . That was great but I wanted to if U do any acitivities to learn something without use of computer, like just using pencil and paper and practicing. How to learn new thing without long use of electronice devices ? I am asking this because 'learning from youtube or anki' all are times to be sitting front of ur computer. IF we could just learn few important things from internet then later just revise it on paper or mind. It could save us time and increase frequency. If you do such things. How do u do it ? I am pretty sure its far better than mine.
Derek Banas (12 days ago)
Yes I think presenting information in numerous ways is best. Read, write, use traditional flash cards and then Anki after you feel 50% of the time you know the answer.

Reventon134 (18 days ago)
I wasted so much time trying to figure out why Julia throws errors at me at the very first example code... Turns out I had to delete the 'using abc' lines at the beginning... Maybe it's the difference in versions, our professor wanted us to use 0.6.4. Still, very frustrating, but now I can finally follow the tutorial, I'm 10 minutes in so far and it's great!
Reventon134 (18 days ago)
+Derek Banas using printf and using statistics, tried many things with the package manager to get those coz Julia would constantly tell me that either a package is not installed or not recognised. Then I randomly commented those lines out and now it's fine. You probably downloaded the most recent version, so maybe there are some differences between them.
Derek Banas (18 days ago)
Thank you :) I’m not sure where the using abc came from?
Muhammed Ali (19 days ago)

Hi Derek, thank you. Your one-videos are great. Can you make one for ELM? There is no a proper tut for it. Btw how about frameworks like amber, the Crystal web framework? Thank you again.

Hello. Unrelated comment but I thought it'd be best to put it here. I'm having trouble using CSS on android. It seems my device's HTML viewer doesn't read and compile the CSS even if it's accurate. Should I use a special app for reading CSS? Help me out please.

I’m glad you liked it :) I’ll make the videos in order based on votes. MatLab is coming next
Abeltensor (22 days ago)
Very nice as always. I particularly liked that you threw in a small explanation about the use case for Julia before jumping into the main video. As a side note, not the biggest fan of the Julia syntax, its like ruby mixed with python and c++. Tired using Julia a few times for machine learning problems and always end up back with python or go I wonder how powerful the macro system is compared to rust or lisp. More languages need a meta programming system.

Youcamp (22 days ago)
Great video! Thanks! I'd love to see you do a video on making desktop apps written with a GUI in Julia. For me at least, writing the application is pretty easy, but writing with a GUI lib is a pain. I grew up using xterm, so maybe I'm just stubborn and have a mental block. lol
Youcamp (21 days ago)
+Derek Banas Okay, I guess I need to qualify that. I meant in my professional life. But if we're going all the way back, my first computer was a KIM. And then like you a TRS-80. But my favorite back then was a Southwest TP 6809 kit running Flex or Uniflex OSs. Ah the good ol days...

Do you think you could do a fortran tutorial? 🙂 I already know a little fortran, but I’d love to learn more 😛
TheEars99 (22 days ago)
Derek Banas good to know 🙂 Fortran isn’t exactly a “popular” language, considering its EXTREMELY niche, but I think it’s still useful 🙂

It’s on the list and I’m making tutorials in the order of what is most requested

Me too although that book in the description may not work for the latest version of Julia since in 0.7 there were breaking changes for the preparation of 1.0.0
Derek Banas (22 days ago)
I’m happy you liked it :)
Niles Black (22 days ago)
What exactly is Julia *for*? Rather; what niche does it fill (that wasn't already full)? This question is for anyone, not just Derek.
Derek Banas (22 days ago)
It is great for data analysis, modeling, simulations, etc. Thank you :) Sorry it took so long to answer. My computer is now officially dead :( I’m answering comments on mobile
Niles Black (22 days ago)
+Derek Banas Thanks for the quick answer! (And also generally for making all these excellent videos). Would you say it's useful for writing and deploying applications, or is it more of an application in itself, which can be used for rapid computation?
Derek Banas (22 days ago)
Julia is for someone looking for a fast language, that makes it easy to use libraries from other languages, looks a lot like Python and has a few features specific to MatLab.

Niles Black (22 days ago)
At 9:13, why would string comparison consider "Takao" greater than "Hiyama"? What metric is being measured, obviously not length or order alphabetically...?
109 103 116 111 119 (5 days ago)
Something about lexicographical order. Fire up the Julia repl and plug these commands in: > “T” > “H” > ‘T’ > ‘H’ > Int(‘T’) > Int(‘H’) > “T” > “Hiyama” #all the above will return true Int(‘T’) #equals 84 Int(‘H’) #equals 72 Maybe somebody smarter can explain why the total length of the strings doesn’t seem to affect the outcome but 84 > 72

Is there a good usage for it? Or is it mostly theorethical?
Derek Banas (22 days ago)
I can make a tutorial on anything with enough requests
Selcuk Caglar (22 days ago)
I think we should consider Rust programing new version. There is a trade-off between safety and easiness. Rust safety gives me performance boost at parallel executions. There is no memory interferance. But julia has trackdown all the varible for thread safety. Julia deosn't throw an any error or warning for memory interferance issue.

if you're covering hipster languages now, could you cover Nim later?
SixGorillion (2 days ago)
+Derek Banas I second the vote for Nim! Coincidentally, I have been comparing Nim, Julia, and Crystal as potential candidates for a project. I see you must be on a similar train of thought because you just did videos on Crystal and Julia!

thank you derek bananas after this tutorial I learned everything about the Julia language and I joined the dev team full time working on lifetime concurrency, atomics, and memory models. This taught me everything I needed to know. From if statements, to julia's jit garbage collector's sweep analysis. much appreciated! By the way, we are adding a Derek keyword in version 1.1. stay tuned

i didnt watched the arduinu tutorial mainly because i have now project idearight now... But the idea with the a self written compiler is very nice. After a bit of research i found this compiler framework LLVM or Bison maybe that could be a good startpoint.
Stanislav Vladev (22 days ago)
oh yes this would be great. Some people want to write a compiler.
Derek Banas (22 days ago)
I won’t quit YT. The fact is that if I continue to explore new tutorial ideas that some will fail. I’m ok with that. The only issue was that I wanted to make really awesome projects, but because they were expensive I had to stop mainly for money reasons.
Exodus (22 days ago)
+Derek Banas I am truly sorry your Arduino series isn't getting enough views. I watched it it was super clear, I don't know why people stopped following it after the first few videos :( But please don't quit YouTube because of it :( I understand it can cause frustration, so learn in ones are always the way to go :)
