A Dev' Story
Spain
Registrace 31. 12. 2019
Topics for the different stages of a Software Developer life, from Junior Devs to Principal Engineer and beyond!
These have been topics that I've found very important to know both as a programmer, but also when preparing for technical interviews, and when growing as a software developer. I will try to tell them from my life's perspective, with the timeline as playlists, so you will get the full journey on learning Computer Science fundamentals from the basics to more seniority. Or in other words: A Dev' Story :)

just stumbled on this channel and its so good. plz keep making vids
Glad to hear ! I'll be posting some new videos soon
Your tutorials are simple to understand as a software developer
Thank you very much! Glad you enjoyed them!
I do wish they would stop flicking the screen, I find it distracting and irritating to watch. I understand if they mess up and need to cut, but I think some of the switching is deliberate or not ver sychnonsed with the next take
Sorry about that. In newer videos it's smoother as I've tried to improve continuous recording. As a viewer I can also agree it's sometimes annoying
I noticed a couple of people already said thank you, I just wanted to add on that. These videos have been awesome great help, thanks man, keep it up!!!
Oh thank you very much! Will try to post more soon. Anything that you'd be interested?
I didn’t your point regarding “language agnostic”… Why would I need a language-based package? HTTP wouldn’t be enough?
Yes HTTP would be the protocol but typically you will call it from one service to call another service. These are implemented in a specific language. Each language will have utils to make it easier to make http calls, and the higher level you code, the less you deal with the specific details of lower level like the http protocol
@@ADevStory That has nothing to do with the service discovery itself. You interact with it using HTTP. Would it be useful to create a package that implements theunderline HTTP calls and exposes functions? For sure. But you can say that about any service. When you interact with Authentication service you will probably use some sort of Auth0 package. However, that doesn't make Auth0 is language-agnostic right?
That's actually the point. If the network routing is hidden to your service (proxy) you don't need to implement anything on the client. If you have the routing in the client then you need to implement it. Not possible to make it language-agnostic because is on the client. You can create a generic library but your actual service needs to call that library. In the proxy one you just call another URL that will get you what you want. Hope is clearer :)
Why the annoying music?
Typically is a bit better for focus to have some background music, but maybe it was a bit loud on this one
Time consuming but I prefer assignment because they tend to be closer to what I actually do
Yeah. I wasn't too happy about it first time but also agree is closer to the real job
I wonder on min 5:11 where there is an composition drawn between Vehicle and Tire, shouldn't the owning (filled diamond) be on the Vehicle side?
Great explanation thank you

Why the Order service does not need to know about the "Order Purchased" event from the payment service? How then the order service will know that order is sucessfull?
It depends on the modeling but the message in the video is that unless you need to rollback some information, you can assume it went ok and the event propagation will take care of it.

Yeah. Technically is reverb (I've been learning since this video 😅) hope you still were able to enjoy the content. The newer videos have better sound
@@ADevStory reverb is just a lot of echoes... but that is great news.
I've watched about 4-5 of this series so far and it's great! I love how succinct and clear you make the main points and the final presentations. Great job!
Thank you very much! Glad it was useful! Please let me know of there are more topics you may be interested
Thank you for your series of videos, which are of great help to my lazy and irresponsible teacher.
You are welcome! Hope things improve on your side!
This is applied for instances as well in a composition for example
I really enjoyed this playlist on SW Arc. Well done!

Is this Steve Jobs teaching Event Driven Architecture? Was very smooth and convincing 😄.

Good content. Background music is unnecessary and annoying. It makes difficult to focus on what you say.
Thank you! Will try to minimize it in next videos!
I want to ask about the Event Sourcing and CRUD. For example, an Authentication service has API to register new users and a News Feed service generates recommendation for that new user. In this case, Auth service can send USER_CREATED to the Event Log to follow the event sourcing. However, in the case that Event Log is not reachable then you will need an outbox pattern where the Auth service stores events in its local database and send to event log later. I want to ask if it is normal to not use CRUD in the register API and the register API will publish an REGISTER_USER event without storing the data, the auth service has an internal worker that will subscribe to the REGISTER_USER event to store data to its local database and then publish an USER_CREATED event for external services. In this case, no need to do an outbox pattern with the assumption that event log will be high availability.
The event log should always be high availability to prevent that pattern you are mentioning, but it can still happen. It's also OK to combine the patterns as you are mentioning too. At the end these are pieces that can be put together to solve a business problem in the best way possible. Here the typical principles like "Keep It Simple" are relevant. If you can solve the problem with CRUD solve it with it as it will be simpler. If you have multiple that need to be orchestrated and Event Driven works better for you, take that path. If you are having a huge disparity between reads and writes, Event Sourcing and CQRS can help too. Hope it's clearer :)
@@ADevStory thanks. I have better understanding now. The pattern where the api handlers don't perform write but publish and listen to the same events is called listen to yourself. However, for the user registration I believe that it is better to use CRUD directly at the handler and using outbox pattern to prevent event log downtime. The reason is that user's personal data is sensitive and it shouldn't be stored in the immutable event log.
It can still be stored in a secured event log. Just like the database needs to be secured. You can also have retention policy for the data in the log too
cant believe you helped me revise this in 2 mins. thanks
Glad I could help!
What’s with the background music? Like seriously why?
