i learn more from ur 30 - 40 mins than my 2 hour lectures

[@SaurabhGuptaicecool]

This series is like godly for interview preps.

[@TusharMehmi]

I think yours are the only videos on KZbin for learning Design patterns thoroughly without even reading anything, really thankful for that and please never stop making videos.

[@santoshkumarganji]

Hi Christopher, Thanks for making such a wonderful videos on design patterns. I just come across your videos while searching for design patterns in youtube. I have gone through all of your videos on design patterns. I say these are simply excellent. Keep up the pace. Expecting all GOF design patterns through your videos.

[@ChristopherOkhravi]

+santosh ganji Solid. I'm glad to hear. About all the GOF patterns, I've been thinking about whether I should indeed cover all of them. I was intending to only do the ones in Head First but since the videos have been quite well received I might make a video for the remaining patterns in the GOF book. Thanks for commenting! And thanks for watching :)

You probably dont give a shit but does anyone know a trick to get back into an instagram account?? I was stupid forgot the account password. I would love any tricks you can give me!

@Theodore Braxton instablaster :)

[@theodorebraxton4509]

@Jon Roland I really appreciate your reply. I found the site thru google and Im waiting for the hacking stuff now. Takes a while so I will reply here later when my account password hopefully is recovered.

[@alim80]

Thank you, Christopher, these are honestly the best design pattern videos I have seen and help me to really understand them. I look forward to the next video :)

[@ChristopherOkhravi]

+Ali Morrison Thanks! I'm glad to hear the content is valuable. Next coming soon :)

[@kushiskinng]

My god.. that transformer vs the plug difference to explain the difference b/w adapter and decorator is amazing! This would remain with me forever now. Thanks Chris!

[@pinkponyofprey1965]

Oh, man, finally a dyed in the wool bona fide natural born teacher!!! If there were teachers like these around when I was a kid I would have paid attention first time around. But ... they spread the info out over a complete year that it took mr Okhravi less than half an hour to explain. Well, I ain't dead yet so I can learn this now instead! :D

[@johnyepthomi892]

You’re passion is infectious. Hope you keep this going .

[@Themicke90able]

Dina videos är dom absolut bästa jag har sett på länge. Sättet du förklarar på är extremt pedagogiskt! Tack för att du har gjort dom här videorna!

[@brunon.8962]

This should be the first chapter of the book, it explains composition, delegation, asociation in a very simple way.

[@ChristopherOkhravi]

Very good point!

[@MrRemyguy]

This is better than the "Best Selling" Udemy course on Design Patterns. I know cuz I bought it and now regretting.

[@diego99799]

Your videos are one of the few things I cant wait. Thank you!

[@ChristopherOkhravi]

+Olaf Olafski Haha thank you I'm glad to hear :)

[@djBC10000]

I like how you teach man, it is very clear and simple to understand, and I appreciate all of the efforts you are putting.

[@isserzack4641]

Thank you for the great tutorials. You put so much effort on this and I should say that you made it crystal clear. Please continue this series and keep sharing with us your knowledge.

[@YazanAlaboudi]

Great video again. Whenever I try to explain this to anyone, I typically try to give an example where I'm trying to save some entity to a database. Then I explain the database may change but should not really affect the modelling of our program.

[@josecarlosramirez486]

I had an exposition in university about this design pattern yesterday. You taught me how to explain this in a way that people can understand it, and I'm really thankful for that. Happy holidays Christopher :)

[@ChristopherOkhravi]

I’m humbled and really glad to hear that. Congrats on the success! And happy holidays to you too :)

[@jongrant6385]

Amazing videos mate - loved the transition at 4:14 :P

[@JohnDoe-ej6vm]

:D

[@a_green_cat]

i really like how you always repeat things, i find it really difficult to focus on lectures and spoken word in general but with your videos i never lose track

[@jayakapoor]

Thank you Christopher for making these videos. These are the best videos that I ever came across on design patterns. I have watched all the videos and eagerly waiting for next one...

[@shivamsaxena7378]

The best explanation of design patterns I have come across on the internet. Great work man, you got a new subscriber! :)

[@nikitavorotnyak9661]

Excellent editing, making your videos very fluid and easy to digest! Great videos!

[@giveexamples]

Before you, learning the design patterns was absolutely tough for me, but after watching your great and subjective videos, everything has changed; TADA. Again the best adapter explanation I have ever seen.Thank you man.

[@sohamsmarty]

My friend, you are one of the most thorough teacher of these topics that I have come across. Thank you for this video!

[@liangsitao]

Thank you Christopher, for recording the whole discussion, instead of making lectures. The videos and in super headfirst manner and I am able to focus and grasp the concepts and rationale behind these patterns. And most importantly I learnt from you on how to read a technical book and present our own interpretation. 👍

[@karapasi6206]

You are amazing Christopher. So much dedication and passion. You actually created desire to learn and dive into these concepts. Thanks a lot.

[@kasperwesteraa9558]

You are very good at explaining how design patterns work! Love it!

[@FebiMettasari]

I really enjoy your explanations on design patterns, it helps me a lot in my OOAD class 💙

[@user-xi9un9qm1u]

Yet another great video The series is incredibly clear, Thanks a lot Waiting for the next one

[@ChristopherOkhravi]

Thanks! And thanks for following the series. Next is on its way :)

[@alvarezmartin]

Christopher: I've just found you....and I have to say that it is the best explanation that I saw about design patterns. I'll see other videos. Thanks from Argentina! Martin!

[@oliviermarty4514]

Great video, i'm watching all of them and always looking forward for the next one. I manipulated in the past, when working on android projects, a thing they called a List Adapter that would interface together a collection of POD/primitive data objects and a collection of graphical/UI objects. At the time i wasn't really digging into those design patterns thing but now thanks to you I have a better understanding of what this adapter did.

[@lakepee]

This is super incredible to learn design principles. I’m really happy I found this video

[@dennisvanotterdijk]

Love the practical examples that you use to demonstrate the design pattern! Thanks for the effort you're putting into this...

[@hk318i]

A good example, in scientific computing where parallel computing is required, an adapter could be used to wrap/hide MP or/and MPI. That also simplify the interface of such external libraries.

[@ZsoltGaramszegi]

Christopher, you always say you don’t know this you don’t know that, yet you explain it very understandably. :) Thank you!

[@matimozg]

I love that way of studing. It's fun, and you get me knowledge in easier way. Thanks a lot man!

[@PuHLiY92]

Спасибо за объяснение. Не зная язык - понял всё, благодаря жестикуляции.)

[@brocoli7006]

Love the transitions in this one :D But really, this videos are very easy to understand and have a good structure! love It!!

[@BrunoPouliotLeCanardNoir]

Just want to say, i love the way teaching us 😉.

[@learn-cool-kids]

Thanks Christopher, the pedagogy is super good and it helps a lot after going through the books.

[@jmendowski]

Thanks a lot for ur effort on these videos. I have watched all patterns videos. Every programmer should watch them.

[@nehanigam4997]

Thank you Christopher for making usch wonderful and energetic videos.

[@chornge1]

I have both design books and have been lacking the time to thoroughly go through them, so thank u!!!

[@ChristopherOkhravi]

+Christian M Solid. Makes me glad to hear that the videos work as a complement. Thanks for sharing and for watching :)

[@gayathrimahalingam95]

The way you simplify and explain it is extremely commendable. I am preparing for an interview after a break in my career . On searching for relevant videos, yours is the best I would say, Thanks a lot. You bring in so much clarity by explaining it with simplest possible examples . Great teaching.. Thanks a lot. Could not resist appreciating your effort. I am pausing the video in the middle and typing this. Great job sir.

[@systemdesignog]

Hi Christopher, I was going through head first book, and got confused with examples. But you explained those examples very well. Thanks !!

[@javacoco5047]

great work!!! you inspire me for my upcoming bachelor thesis - thank you, so helpful!

[@antenna7851]

I barely comment to youtube videos but i was compelled to write to this one. That was such a nice example and explanation. Your energy definitely made it a lot easier to watch as well. Thanks

[@fordsim7]

Love the explanation. Quick and easy to understand!

Thanks! And thank you for the code walks shoutout :)

[@rongliao9255]

Very clear and concise explanation with engaging teaching style!

[@Blaskillo]

Hello Chris, again awesome video, I did not know that adapter pattern was also known as a wrapper, but thank you for mentioning that at the beginning of the video, it makes totally sense to be called like that

[@ribaker822]

Thank you for these videos Christopher.

[@thereversejosh]

Hi Christopher. This has been the best explanation I've seen. Immediately liked the video and subscribed to your channel! You earned yourself a new fan 😁

[@safvanp567]

Thank you so much for this playlist, I highly appreciate your hard work in creating lectures

[@kerstiny4698]

I truly wish that more lecturers can teach from the perspective of students, just like you do! I pay a ton in tuition but sometimes just don't get much digestible knowledge in return. There are professors that don't even bother to tailor the publicly available slides to their actual need, let along writing notes on board. They just read thru or fly thru some slide and give random thoughts. While this might work for advanced class, it's absolutely a nightmare for any introductory course. Sir you deserve a larger platform, and I wish you all the best!

[@ankitgupta8215]

Awesome videos!! I was waiting since long for such videos..Simply Excellent Work :) . Please keep on posting.

[@chaoukimansour7816]

Best deign pattern videos out there ! Thanks Christopher

Probably the best example of the Adapter Pattern I've seen

[@RafaellLycan]

Chris you saved my life today. I'm working with a legacy application that's expanding to another country and now we need to integrate with different third-party apps. Thank you and when you visit Barcelona remember me that I own you a beer. Take care

[@ChristopherOkhravi]

+Rafaell Lycan Hah! That's awesome I'm super glad to hear! High five for solving the issues you faced! :) And thanks for the beer :) :) :)

[@delucabruno]

This video needs more views, very helpful!

[@dscheme4427]

Cool stuff bro, keep doing 'em. What I would like to see is the adapter pattern explained in terms of how to, for example, draw different tree-views based on a composite pattern. Maybe you'll get there later, just started watching.

[@nikhilemmanuel9511]

Well for not a good "reader" like me, your videos has been so clear and understanding. thanks a ton bro. keep it going.

[@balajim6628]

Thatnks a lot Christopher for making these videos, you are explaining very well, easy to understand, I am not referring any books. your videos are enough.. .:)

Oh man, you explained the adapter pattern in a great way! I subscribe to the channel and am going to watch your other videos :)

[@onnobeckerhof5790]

Brilliant. Thank you so much!

[@tobidaada]

This was really well done. I love your style of teaching and enthusiasm.

[@AZ-mi2wj]

Very nice video! Well explained!

[@VikramKaull]

Hi Christopher Another great video explaining the pattern! Thank you so much for sharing! I wanted to point out more about using the Adapter pattern for an external library. It's definitely a good idea to encapsulate all your external DAO calls in the adapter pattern, like calling a database or an external service. Another reason is Exception handling. For whatever reason you have defined your own exception type hierarchy (transient or permanent exceptions) in your code base. And you want to translate the exceptions thrown by your external dependency. Adapter pattern is good for that because you can wrap the call to adaptee.speceficRequest() in a try{} catch{} and re-throw exceptions of your own type. One useful point of rethrowing exceptions of your own type is to have different retry policies for different kind of exceptions. Thanks again for sharing the video!

[@cdmapplications]

Another great job! Keep it up Christopher!

[@ChristopherOkhravi]

Thanks! And thanks for sticking around :)

[@botrate412]

Wow! Clear, creative, understandable english. Subscribed.

[@shaktisingh-lu3dm]

Great Video. Very understandable. Many thanks for such videos.

[@taras_anichyn]

Thanks for that video. Very clear explanation.

[@mireazma]

The key lies in 17:19, otherwise (without DI) the whole thing would be useless because if we hardwire Adaptee into the client, we might as well call SpecificRequest(). OTOH we could make Adaptee implement from IAdaptee with IAdaptee.SpecificRequest().

[@TheMcallist1]

Beautiful. Thanks!

[@nareshbonagiri6932]

Hi Christopher, Thank you very much for making the excellent videos on design pattern and your explanation is damn good. thanks again
