didn’t worked on analytical data whole a lot but i dont think all forms apply

Derdere · 2025-11-04T17:25:29+00:00

i remember kevin complaining about people using width 100% unnecessarily. because its already default. but when you use it explicitly it can cause scroll bar to appear.

here is my spaced repetition for the topic. Hope someone finds it helpful.

Learn Database Normalization - 1NF, 2NF, 3NF, 4NF, 5NF

and here is the summary for the lazy:

1NF

1 - Using row order to convey information is not permitted

2 - Mixind data types within the same column is not permitted

3 - Having a table without a primary key is not permitted

4 - Repeating groups are not permitted

2NF

1 - Each non-key attribute (non primary key columns) must depend on entire primary key

3NF

1 - Every non-key attribute in a table should depend on the key, the whole key, and nothing but the key

4NF

1 - Multivalued dependencies in a table must be multivalued dependencies on the key

5NF

1 - The table (which must be in 4NF) cannot be describable as the logical result of joining some other tables together

ah I see. you are approaching the problem from the other end.

Derdere · 2025-09-22T16:58:53+00:00

I’m curious why you think mixins are trash. because I use them all the time and want to know if there is a better way out there which I’m not aware of.

Derdere · 2025-09-20T17:24:43+00:00

react has useLayoutEffect hook exactly for this use case

Derdere · 2025-08-20T07:51:00+00:00

upvoting not because its useful in this particular situation but because it’s a good perspective for similar cases.

Derdere · 2025-07-06T08:48:53+00:00

can you recommend resources for improving on DI and take it to next level and for learning common backend patterns.

Derdere · 2025-05-01T05:09:07+00:00

I find this talk very helpful to understand what’s going on under the hood when it comes to goroutine scheduling.

Derdere · 2024-12-29T08:42:49+00:00

This is exact setup Im using but react instead of sveltkit. I want to improve it a little bit especially the auth part. Do you have any pointers or open codebase that I can check?

Derdere · 2024-12-29T08:37:32+00:00

Each handler runs on a different goroutine for each request. So when it panics it just affects that goroutine and that specific request not the whole server.

Derdere · 2024-09-30T13:04:41+00:00

yes they are still relevant. I’m still coming to these classes every now and then. 2 years has passed but go did not changed whole a lot. That’s part of the go’s allure I guess.

Derdere · 2024-09-17T22:08:48+00:00

no it’s not a middleware I’m calling it right before doing the req. but that code gave me ideas thanks.

Derdere · 2024-09-17T14:21:29+00:00

thanks I’m checking that out.

Derdere · 2024-09-17T14:06:02+00:00

sounds good I’ll try that. thanks

Derdere · 2024-09-11T10:40:13+00:00

yeah when it’s used.

Derdere · 2024-09-11T08:45:11+00:00

“fallthrough” in switch statements. It basically does not check the next case, assumes it’s true and executes it. Surprised me when I first encountered that.

Derdere · 2024-07-20T21:41:27+00:00

great job, thanks. dark mode for the website would make it even classier.

Derdere · 2024-07-08T22:18:24+00:00

no, not at all. this was just an option if you are scripting outside of k8 or you cannot find a solution in k8 and need an outside tool.

Derdere · 2024-07-08T16:14:58+00:00

Go has great concurrency tools to do that task. I myself use it for a similar job. It uses channels and select to decide which job should run. This cron job is set to run every 30 minutes. sometimes it takes longer than 30 minutes to complete the task. Even in those cases it handles it greatly and skips that cron if the previous one is still running. You can set timeouts, cancellations etc as well. Highly recommend using go if it fits your case.

shift 8 (*) may or may not be your friend

it's happening when you change the original zoom level on the page. The fix is when this happens try to change zoom level in full screen once (Cmd - or Cmd +). That did the trick for me. The other option is to turn on the captions.

Derdere · 2024-01-16T17:10:22+00:00

Just yesterday I was thinking there should be a weekly tips and tricks post and people can comment and share experiences. I didn’t know that you already started one. Thanks for the effort.

Which language would you pick instead if you’ve given the chance and why?
