My monads hurt

Tony Danza: “Monad!!”

Good video, thanks for sharing

One small correction: grapheme is a part of a particular writing system. Writing systems are always language-related. Unicode does not reflect any particular writing system. Unicode, and this is probably the smartest choice that could ever be made, maps numbers (code points) to character descriptions or names. This way Unicode is detached from any font and therefore from any particular shapes. This results in a code point relating to not what we want to see, but what we want, making it more abstract. A good examples are <g> U+0067 and <ɡ> U+0261. In most writing systems based on Latin script, they are allographs, variants of <g> grapheme, so if Unicode were to contain graphemes, there should be only one character. But this is not the case. A writing system may prefer particular glyph (a shape of a letter) and that glyph could be the main variant (allograph) of the grapheme in that system. In most Latin-based writing systems <g> is the main variant, but in the International Phonetic Alphabet it is <ɡ>, because of it correlation with other similar characters like <ŋ j>.

Excellent video again, I wish you best and hope to learn more intersting concepts from you Alex.

You earned a subscriber today. I've worked in the past with non-english characters scratching my head. This alone sums up all the concepts in details. Very good use of examples and video production 💌

Feels like all generic types are monads.

the shitty music interferes

2:00 Every single language translates to the name for the language in that language except Arabic. At first I was wondering why but then I realised: you wrote Arabic from left to right. It's supposed to be tfel ot thgir.

Hey, important stuff to know about getting your money back!

always know it's a great explanation when it starts with the problem being solved, thanks for the pleasant listen :)

please come back mr alex clockwork. i am 14 and these videos have intrigued me a lot and i can learn a lot from these.

Your Bitcoin transfer has been processed successfully-congratulations!

Hey, your Sales Incentive payment is all sorted out and good to go!

Poetically, behold the confirmation of the ethereal journey of funds from the bank to your Visa/Mastercard card.

UTF-32 is so much better, why we still using UTF-8? It's so strange to see no logic in IT where logic is everything. 🤨

Bestestestestes... explanation of Bayes Theorem. While the others only try to get math and die tryin

I wonder how two other illustrations might illustrate issues which can arise with servers. One: the counter clerk at the ice cream store is doing fine until one of the ice cream buckets runs empty, so they have to go get another from the freezer, and a line forms. Two: Now the customers are angry about the line, and each one wants to register a complaint, which decreases the intrinsic throughput. So the process of getting another bucket and any decrease in throughput from the hard-frozen data (I mean ice cream) along with complaints, ends up creating bigger and bigger issues.

By the unfortunate turn of events, a system error led to the transaction being sent to an invalid email address.

Hi, I have some awesome news that will bring a smile to your face!

We hereby confirm the successful reception of the BTC transaction.

Huh... I did not know about slow hashing techniques! Thanks for the video!

In other words, monad are the coping mechanism static typing zealots use, instead of accepting dynamic typing, reflection and metadata.

The option monad does not fit into the unwrap-transform alternating pattern, because the none cannot be unwrapped and the transform is never called in the case of none.

Let me anger some nerds with oversimplification. It's basically just a context. Classes aren't too far. 8+6? = 14 8am + 6? = 2pm The context completely changes how we interpret operations. Let `mix` be my function. Mix numbers? Doesn't make sense. Mix colors? Makes sense. Maybe I have just a trio of numbers, (69, 69, 69). If I wrap it in with the context of Color (Color (Int,Int,Int)), the set of operations that make sense in the context changes. The Java approach to classes (selectively exposing member variables/functions) gets pretty dang close to the idea/utility. Now all we need is some popcorn for the "weeelll axxcctuallly 🤓" crowd.

Typescript is such an ugly language. Python would of been a better choice to use.

The Den of the Dragonettes Our friends had a good start and were able to maintain it, for with their eight wings they could go just as fast as could the Gargoyles.

Just what I needed. Thanks mehn

Really great video. Especially the cinematics!!

finally, someone explained to me how it's called what i have been using blindly for at least a decade. some language adepts love to make a "wow" out of something regular.

Thx bro, you really help me

Excellent video! Thank you :D

Not a good video.. there are better videos explaining these concepts much simpler and easier way

I... still don't really understand what "a monad" is. Like, I understand the design pattern you're showing off, but what is "a" monad?

direct to the point, thanks !!

fantastic video..loved it

i read mcdonalds :(

Nice one, thank you. At about 2:00 I would have called the inner and outer square rather than the first and second one.

Lose the background music. Couldn't get through a quarter because it's so distracting

Very good video! Thank you a lot!

Just to be nitpicky, the wrapper of the type is not a part of the monad. The (in)famous sentence is true: A monad on A is a monoid of the endofunctors of A. This means that the it is a F: A -> A, meaning that both the original object and the end object must belong to the same category. In your examples, you are doing two different operations: - An isomorphism, F: U -> W, where U are all the unwrapped objects and W are the corresponding unwrapped objects. - A monad, G: W -> W, where the monad acts on any wrapped object and returns the same type of wrapped object. Not that it is fundamental to program or anything, as most of the time combining both is the easiest solution (multiple times my functions accept different types for certain arguments and I internally transform those arguments into the type that I actually use in the function, like passing the name of a matplotlib cmap, and then I get the cmap, but also allowing to pass a cmap itself). Another nitpick to make is that in pure functional programming, the "busy logic behind the scenes" cannot affect anything else other than the object being returned. For example, if instead of adding the log to the object you wrote it somewhere else, that also wouldn't be a monad, even if that function would work exactly in the same way, being able to chain it as much as you want.

A monad is a function that takes an object of any type and returns the same type of object. Map and filter are two very understandeable monads. In Pandas, for example, getting rows by index is a monad, as you had a database before, and the function (selecting indices) returns you to another database object (to which you could further apply an index selection).

It's a great explanation of complex concept. Divinding work time into CPU and IO time is a realy great concept for understanding this. Now I understand why Node.js is so popuar for web development. Thanks!

I wish loud soundbed musak wasn't considered de rigour everywhere ATM. it really is very distracting not some kind of educational aid.

oh you call it run? I call it apply

1:09 But doesn't ascii use 7 bits for representation ?

i feel like im losing my sanity watching this thats how you know its good
