getDiscount() should be with lesson as it will hide the way discounts are being calculate from cart.

excellent, this is the perfect way to teach, 13 went off very fast for me while watching this video

At 4:27, I was just waiting for her to say the term "Single point of failure". As soon as she said it, man that felt so good!

this will help me to understand the logic but hands on will give clear idea how its actually work

What doesn't make sense to me is if 1Gb = 10^9, then why is it called billion and not gillion. Why consfuse? It should be million gillion trillion.

Please create a video on API Standards: RPC, SOAP, REST; when and where to use with examples.

I think it should be possible to do this . A single server can have networking rules application which can handle incoming data from clients for security purposes or business purposes. The same server could also support outgoing traffic by keeping a check on data and have rules if needed . Example: vpn or maybe a dns. My query How to decide in what cases we should use fwd vs reverse case?

1. Persistence layer : this would be data saved into the system to perform analytics or data processing etc Example databases - sql,nosql. 2. Client layer: some kind of minimal interaction or the way to enter into a system would be needed for the user. These are our thin and thick clients. Example : app or may as well be a console. 3.server layer: this would be the layer where the clients request would be usually processed I believe these are the bare minimums I'd need. Now depending on complexity, we may have client side caching such as cookies or client side storage as well or may as well use CDN(Content delivery network). Also a server side caching can be used to avoid computational cost if the data tends not to change too often. It is usually required in scaling and higher efficiency requirements. We may also try to introduce queues or streams to handle higher throughput. Please let me know if i was able to answer the quiz. Here is my query How to decide which type of database to use based on the data. Example:in my whatsapp where it is a small group chat server with e2e encryption(meaning a thick client) and more writes but lesser reads. Which db should have been used here?

If you can take a example project where we have a mobile app, web app with backend (lets say 4 services in Java) then explain how to estimate for 5000 DAUs and how to prepare the BOM that would be much helpful

what a nice value addition to my engineering life. I am enjoying watching the design pattern playlist. It's above par comparing to any paid courses. Thanks a lot ....

Your lessons are to the point and concise. Thanks for that If possible, can you make videos on SOAP architecture? And on RPC?

Thanks alot

I am in disagreement with that we need to avoid distributed transactions, distributed transactions are very common in microservices and sagas are used most of the time to ensure eventual consistency.

can we post request directly from chrome browser??

Is it possible to write a consumer for DLQ?

Simplified explanation, thankyou!!

Hi, Is there any kind of interview that will happen after we submit the application, or we directly get the result after the application submission...?

nice one

❤❤❤❤

Thanks

So grateful for this channel. I wish you live long to bless us with your knowledge.

please fix ur audio , voice is too very less

Crystal Clear Explanation!

Analogy - A translator in between two foreign Language speaker :) The translator translates the words of the speaker and tells the listener what the speaker is giving as an output!

How can Arrays.asList is example of adaptor?

42 year old dev, looking forward to this. I suffer from overload and I'm usually spending my days just being in meetings.

when i try to login with google, from the instagram of daily dev. i cannot log in, i get error, can someone check if there is smthing wrong in the backend?

Excellent explanation it helps a lot keep up good work…thank you so much it’s really helpful ❤

Long time no see

aare hindi me bol le bhan

Great stuff

❤

Thanks..

wonderful @sudoCode chossing a right Sharding key or combinations is crucial and needs advised an deep decisions ... kudos to you!

Very Good Tutorial! Simplified the concept like anything. Sharding Key is a crucial here. Choose sharding if its really needed.. not every organization needed it. choosing wrong sharding key could bring lot of complexities and wrong data to the customer.

Partition P is must in real world for sure... now you have trade off between A & C .. Example of of AP - Social Media like Instagram, Facebook, LinkedIn etc. Where Consistence can be given off for eventual consistence or delayed consistency but Availability and Partiotion are preferred. for example, its okay to wait to read the comments or post r like with some eventual consistency. Example of CP - Banking, Finance where transaction needs consistence following the ACID properties. Where A transaction like sending and receiving funds needs constancy. hence C is must else your core service will have no purpose... now you have trade off between P and A but P is must... so most financial sectors follows PC CAP is itself a huge topic

You said that we define a "private" function getDiscount in MenuItem class and override it in the BeverageItem class, but private methods cannot be overridden.

Just finished watching all of the course. This was very helpful!

You teach a lot better than Gaurav Sen. Why don't you you launch your course on System Design. It would be a great help for all of us.

love the video

The example you have shared is wrong. Properties that do not change should be part of another class, example : BookType. Using composition add BookType in Ball class. Please everyone do not assume everything online is correct, do your analysis as well.

Very nice explaination 👍

I was searching from a lot of different videos. but I liked your way of explanation. now I specifically search for your playlist :)

Whcih the first Video if i want to checkout ?

Example of a thick client architecture: Adobe Photoshop, AutoCAD or SolidWorks Example of a thin client architecture: Citrix Virtual Apps and Desktops, GitHub, GoogleDocs An example of a commonly used system that incorporates both thick client and thin client architectures, along with multiple tiers, is an online banking system. Example of servers behaving as clients: Uber's servers may act as clients to interact with mapping and navigation services, such as Google Maps. Uber's servers communicate with payment APIs like GPay, JusPay, PhonePe, etc. to facilitate transactions, process payments, and generate receipts for riders. When a new user signs up for an Uber account, Uber's servers may interact with identity verification services or authentication providers like Gmail to signup to validate the user's identity and ensure account security.

GOF or head first which was easier to grasp and apply.

Does the additional method of subclass violate the LSP which is not present in the parent class?

Awesome videos, very easy to understand for beginners like me. Thanks a lot.

Thanks for explaining this! I had a low GPA (2.3) due to undiagnosed ADHD and it took me some time to figure out how to learn. I took some graduate courses in cs and got A’s. Think that would help?
