Learn the fundamentals of the backend, scaling and load balancing with my Introduction to NGINX udemy course nginx.husseinnasser.com

[@Andrey-il8rh]

This was one of the most energetic talks I've heard In a while. Keep it up man, the energy and a vibe you put inside your tutorials is addictive 👍

[@apollosilith9026]

This was probably the best dev tutorial I've ever seen. Your energy and humor is infectious; You turned what could've been a frustrating tutorial into something easy, useful, and fun to watch. Well done!

[@VasanthTulasi]

I don't usually put up a comment but I have to appreciate your humorous approach to explaining these complex technical things. You just earned a subscriber :)

[@hnasr]

Thank you dear! Enjoy the content

[@alexeyshevelyov1163]

Personally, rather than script reading videos (with the eyes of the presenter running from left to right) - with this you feel like you drinking a beer with a friend that is telling you all this cool stuff, paying attention to each and every detail, trying to make sure you understand. This is not to say that other videos are not pursuing the same goal. This is to emphasize how much more personal touch this style has and from reading the comments, you can tell it resonates with folks a lot. Again, huge thanks and keep it up!

[@cristianoseixas2417]

Vídeo sensacional, não tem conteúdo melhor explorando protobuffer no youtube. Muito obrigado

[@RobbyLuisa]

Dude, I rarely (never) comment on YT videos. That being said, I watch a lot of tech / dev tutorials... I really enjoy your humorous way of going through the exercise and explaining the different concepts. As already suggested in the comments below: if you continue, I know you'll end up a very popular channel for these type of tutorials. Well done mate! Cheers from Germany.

[@hnasr]

Robert Rottschalk Robert! I really appreciate you taking the time to comment it means so much. Thank you for your kind words, glad you are enjoying the content and cheers to all my subs from Germany 🇩🇪

i guess im asking randomly but does any of you know of a trick to log back into an Instagram account? I was dumb forgot the login password. I would love any tips you can give me!

[@alikhansharapat9933]

and now it became very popular channel :)

[@socialblade7751]

The best yt channel, real life programming .. thx

[@hnasr]

SocialBlade appreciate it thanks 😊

[@zebcode]

Wow this is the video I've been waiting for. I really wanted to know the differences between JSON and protobuff. Really looking forward to GRPC!!!

[@hnasr]

Kiran Randhawa thanks Kiran! That was my purpose as well. I don’t like to use a tech without knowing why it was invented

[@tobiasbergkvist4520]

Extracting protobuf uses a lot more cpu than just parsing JSON. This is very noticable when working with map data. Mapbox Vector Tiles (MVT) uses protobuf under the hood - and compared to sending GeoJSON, a lot more cpu power is required at the client side. At least this is my understanding after doing direct comparisons between MVT and GeoJSON.

[@hnasr]

Interesting point, I thought protobuf benefit is faster deserialization ... maybe this is specific use case with mapping data

[@BboyKeny]

Awesome video. Another point that can be made is that protobufs shouldn't be used for really large files (like images) that you don't want to have live in memory. I'm investigating protobufs and I think is a really cool advantage of it having a schema, is that if you have multiple programs, in different languages, talking to eachother. Αnd more programs might be added for which you don't know the language. Then having a shared schema like this is awesome. Compilation can be done with CI and it seems you can change protobufs without having to go through every old project that's using it (by following certain best practices).

[@juvi925]

Hussein, Thank you so much for your channel! as a junior backend dev, your content has been a god send!!!

[@datapro007]

Truly a fine video Hussein. I like your sense of humor. It makes a dry topic almost tolerable. Thank you!

[@antoniomasotti8060]

Great video as always. Regarding the cons, the two you named apply if you're working on small projects / working alone or with a small team. As soon as you have a more complex project or dozens of Devs (of all levels) working on a project or connected projectS sharing the same data, having a schema becomes a MUST an having to maintain an additional file or update a cli much better than not having a Schema.

[@tejakdluv]

To be frank one of the best vid on the internet explained very well

[@shynggyskassen942]

If protobuf takes less memory and faster to serialize/deserislize, why we still use JSON?

[@fuadcs22]

Because we still need to have the schema on both sides. Json don't require that. It's just data.

[@jindal0001]

I felt it was a long video before I started watching it, but it was fun and really informative. Thanks

[@restuwahyusaputra7764]

Best channel for software engineering, i like this channel, terimakasih husen

[@JustinMasayda]

Thank you for this excellent video, Hussein! One more con of protobuf vs JSON is it's not human readable since it's binary. For certain applications you might want your serialized data to be human readable.

[@airnitro9949]

I am greatful to GOD that i found this channel.

[@BruceCantarim]

The way you teach and explain things is just amazing. Well done! Thank you for this, had to learn protocol buffer quickly for an existing project and this video really got me there.

[@natureloverJ]

Good stuff! Big companies like Google, MS, Amazon, and other big wigs. They create lightning speed APIs by optimizing a lot of things. Protobuf is one of that. It helps to achieve the smallest possible data footprint that helps transferring that binary data over the net very fast. Certainly it is much faster than REST or SOAP. Response time gRPC < REST < SOAP.

[@MrBagginsDoes]

Dude, best Protobuf tutorial I've seen. To be honest, I am using python while watching you and JS, but you explained it so well, that the language does not matter, just like protobuf :D

[@kostyayatsuk2004]

First video of Husseins that I'm watching and gotta say the energy keeps me engaged during moments which in other videos would've been incredibly boring. Definitely gonna take a look at any other videos he produces cause it seems like they would be really good

[@EwenMackenzie]

good video. Bear in mind to be more concise with what you explain and the target audience. thanks it helped me a lot

[@AnothyAtWork]

Great video. I really enjoyed your energy while explaining what Proto Buffers are. I now have a good understanding of what Proto Buffers are. Thanks. I'll be checking out your videos.

[@pablomoraesdemattos2114]

Hello Hussein, my name is Pablo and I'm a student of Control and Automation Engineering at UNISINOS (University of the city of São Leopoldo, Brazil) I'm studying this protocol and I would like to know if you could help me with some information about this technology?

[@ryanleemartin7758]

love your breakdowns . really good. I actually prefer the proto schema to just blasting json for api calls because even though the json itself doesn't have a schema, I'm still serializing and deserializing to types on server and client which is conforming to a kind of implicit schema (my type system). Now, the code gen does that for me. That's very very nice. It doesn't solve every use case but it solves all of mine!

[@david-tracy]

this is interesting. I wonder why I haven't seen this used yet in any of the react tutorials I've been watching throughout the past months

[@ethansherr3281]

If you don't like callbacks... you can import { promisify } from 'util' import fs from fs const writeFile = promisify( fs.writeFile ) ... await writeFile('file/path', JSON.stringify({...})

Subscribed! This was by far the best tutorial available on protocol buffers.

[@shashankm7560]

Hey Hussein, excellent stuff ! one comment though. are we doing an apple to apple comparison by comparing the size of binary protobuff and json data written in file.. Essentially, Json would also be transmitted in the binary format along the wire.. So, rather, would it make sense to compare the footprint of json binary vs protobuff binary ?

[@hnasr]

Shashank M an excellent observation Shanshank!! Yes JSON (if you are using HTTP/2) it will be converted sent in Binary and compressed (that is the key here) however protobuff will still win because the original binary format is way smaller than JSON ..

[@mertackportal6705]

@@hnasr First of all, incredible video. Really helpful. Secondly, this is my question as well. I understand the smaller memory and disk footprints, though I can't wrap my head around how a binary file has smaller network footprint than a JSON file. Assuming they are originating from identical data(Hussein, Ahmed, Rick), the transmitted packets over TCP should also be the same because data will be converted to binary regardless. Protobuf output is just one step ahead -- it is already converted before being transmitted. Ultimately, are we comparing the time it takes for Protoc to convert the data to binary, to TCP converting JSON to binary?

[@KeyserTheRedBeard]

great content Hussein Nasser. I broke that thumbs up on your video. Continue to keep up the great work.

[@vershaverma1409]

Very well explained thankyou for the video!! But I have a doubt, take java for example java has its own serialization mechanism so what is the difference between the serializing mechanism that java offers and protobuff ? and if they are similar then why would anyone use protobuff instead?

[@hnasr]

Good question, every language has its own serialization logic, Java, C#, Javascript, Golang. Those are not compatible with each other. If you serialize a class in Java client you can’t deserialize it “easily” to C# server. Protobuf is a universal standard for serialization for all languages (or supported ones at least)

[@vershaverma1409]

[@Celsian]

Your size comparison is missing the zip compression aspect, where low entropy (JSON) would compress very well, while high entropy (bytes) would not

[@VATSAL372]

I use the zlib and compress. That offers good compression. I wonder if protobuff could be compressed, and if so, would it be worth it?
