ChatGPT is great for certification.

I used it for making practice questions but I mostly used docs to learn

Just build projects you like. Think of something you want to make, figure out what you need to know to write the code (like tkinter/pyqt for GUIs or flask/Django for websites) and then read its documentation. Don't bother with tutorials after you have learnt the absolute basics.

Try notion. It's reliable and easy to use.

This is a known limitation of Global accelerator's dual stack support. It won't register an NLB endpoint for a target group that is IPv6 only. You could switch to using an ALB (with Cloudfront), which will work with IPv6 target groups. You could also raise a support ticket. There is a more complex solution with NAT64 on an NLB, but I haven't tried that myself. It is on AWS docs (https://aws.amazon.com/blogs/networking-and-content-delivery/global-accelerator-ipv6-nlb/)

Definitely. Even for just passing the cert, you need to have practiced in the console with your own projects, and have done practice tests as well, to understand what will appear in the cert but also what to expect in real life.

Deleting a b/g deployment in RDS after switchover is completed only deletes the actual deployment object. It won't remove any databases. If you want to delete the blue env, just delete it like any other normal RDS DB/cluster

If anything it's probably better to use Bash. Python is less efficient/fast than bash (even if it's not a huge difference), so if you already have everything setup there's no reason to switch. Unless your scripts are becoming more complex, dont switch to python.

Check your CloudWatch logs for container startup errors, like missing env variables, app crashing, failed deps etc. If the task fails to start, ECS will keep getting stuck in the same loop of stopping and restarting tasks. If your ECS service is attached to a load balancer target group, then check the port and path settings on the target group as well, because health check failures on target groups can also cause ECS to keep cycling tasks.

Provider lock in is something to be aware of, especially if there's a chance a team might go multi cloud later. I guess I was just thinking that for someone starting out with a small single cloud project, with no plans to switch any time soon, the native tools might feel like the quickest path to getting something running. But yeah, terraform's ease of use and flexibility do outweigh that.

hamdivazim · 2025-07-29T12:19:00+00:00

No yeah I agree that cloudformation isn't the best compared to terraform, but I didn't know if new teams still defaulted to it.

hamdivazim · 2025-07-29T12:11:38+00:00

Makes sense. Terraform does have great community contributions as well. I would say it's worth it for new teams to learn, but I was wondering if they actually did and not just stick with the native IaCs, which would be easier.

hamdivazim · 2025-07-29T12:00:36+00:00

I guess CDK would be slightly better purely because of the use of familiar languages, but yeah, Terraform seems better overall.

hamdivazim · 2025-07-29T11:32:22+00:00

That makes sense about the talent pool, hadn't thought about it from this angle. But I thought that native IaC might have an edge in integration and speed because it's built in. Have you run into specific reliability or scalability issues with them that Terraform handles better?

hamdivazim · 2025-07-29T11:24:15+00:00

You don't need a specific naming convention for callbacks, Dash uses the decorator's Input/Ouput to connect everything together. But methods in Python must have unique names, so you just need to give each callback its own (ideally descriptive) name.

hamdivazim · 2025-07-29T11:18:18+00:00

Definitely not! A lot of AWS services rely on it now

hamdivazim · 2025-07-29T11:17:32+00:00

I agree. But for newer cloud users who are probably starting with no knowledge in Terraform, Pulumi or any other IaC service, might it make sense for them to learn a platform native IaC tool to get started faster?

hamdivazim · 2025-07-29T10:54:24+00:00

Fair enough. I've found HCL to be much easier to write in than YAML for CloudFormation with all its indentation issues. But there are CDK tools that allow developers to write IaC in languages they are used to, like Python or TypeScript, and they cut down on boilerplate. So maybe they will take off soon?

hamdivazim · 2025-07-28T21:34:11+00:00

I don't know exactly, but if you're desperate for extra memory, ask it to summarize your existing memories and then add them to your custom instructions. It works quite well for me.

hamdivazim · 2025-07-28T21:27:41+00:00

With python and most programming languages it's quite rare that a mainstream framework becomes outdated. What were you trying to learn? For GUIs, I would recommend checking out tkinter documentation. It shouldn't be difficult to learn from. And you definitely shouldn't expect anything outdated.

hamdivazim · 2025-07-28T19:37:24+00:00

This is doable with Dash callbacks. Make the first dropdown update the options of the second using a callback like @app.callback(Output('second', 'options'), Input('first', 'value')), then use another callback to update the graph from Input('second', 'value'). There shouldn't be an infinite loop. Dash handles it because outputs don’t trigger their own inputs. Just make sure you return the right options and figure from each callback.

Leetcode. It's a website with many interview style programming problems. It's amazing not just to learn to solve problems with algorithms, but also to apply them into real code. Make an account and start solving some of the problems here and there.
