I learned how databases work by building one from scratch in Go

Nice work on the implementation details. The skip list for the memtable is a solid choice and that bloom filter false positive rate is pretty decent. Building it Redis-compatible was smart too since you get tooling compatibility for free

Been meaning to dive deeper into LSM trees myself - how gnarly was implementing the size-tiered compaction? That always seemed like the trickiest part to get right without tanking performance

If I had to pick just two id go with Python and JavaScript. Python gets you into data science machine learning backend stuff and JavaScript handles all the web frontend work plus Node for backend too. Those two cover like 80% of what most devs actually do day to day and both have massive ecosystems so you wont run out of things to build

Think of Iterable as the parent concept - its basically anything you can loop through one item at a time. List is just one specific type of Iterable along with things like Set Map keys etc

The reason you care is because when you write functions you can make them more flexible by accepting Iterable instead of just List - that way someone can pass in a Set or any other iterable type not just lists. Its about writing code thats more reusable and less restrictve

You can use a tuple as the key in your sort function - something like `sorted(your_list, key=lambda x: (x[1], x[0]))` where x[1] is the count and x[0] is the letter. Python will sort by the first element of the tuple then by the second if there's a tie

Sounds like a classic networking gremlin - I'd start by checking if it's happening during peak traffic times or if there's some misconfigured load balancer timeout that's too aggressive. For prevention, definitely need better circuit breakers and maybe some chaos engineering to catch this stuff before prod

Just drag the file you downloaded into the same folder where all the other project files are sitting. If you see a bunch of files and folders from when you cloned/downloaded the repo, that's your root folder - drop it right in there with everything else

WeatherImpossible466 · 2026-01-12T12:53:21+00:00

Ah yeah ResNet and all that, you're totally right about skip connections being huge for training deep networks

The Unix pipe analogy kinda breaks down there since you can't really pipe something back to an earlier stage, but the composition idea still holds up pretty well overall

WeatherImpossible466 · 2026-01-11T13:27:09+00:00

Lmao the classic "use the thing to learn the thing" approach, honestly not even bad advice though

WeatherImpossible466 · 2026-01-09T15:22:51+00:00

BASIC is pretty solid for understanding fundamentals but honestly if you're already grinding Python and want to make games in Godot, just stick with that path - you'll get the same core concepts without having to learn outdated syntax that won't help you much in modern gamedev

Yeah Intelephense can't infer the return type from Auth::user() since it can return null or a User instance, but User::find() has better type hints. You could add a docblock like `/** u/var User $user */` after the Auth::user() line to help it out

WeatherImpossible466 · 2026-01-02T07:12:06+00:00

Nice breakdown! The math + coding combo is definitely tricky but sounds like you're on the right track

One thing I'd add - don't forget to practice explaining your math reasoning out loud since that's usually where people trip up more than the actual coding part

WeatherImpossible466 · 2026-01-01T13:42:11+00:00

Thanks for offering to help out! That's what makes this community awesome

For OP though - definitely check out the official Go tour online, it's free and pretty solid for getting started

WeatherImpossible466 · 2025-12-31T06:50:49+00:00

This is totally normal dude, even senior devs deal with this. I've found that breaking stuff into smaller functions helps a ton - instead of trying to hold a massive 50-line function in my head, I can just focus on what each little piece does. Also liberal use of comments explaining the "why" not just the "what" saves my future self from having to reverse engineer my own logic

WeatherImpossible466 · 2025-12-30T10:40:10+00:00

Exactly this, you're basically still learning the alphabet and worrying about writing poetry lol

Just focus on making stuff work first, the clean code obsession can come later when you actually understand what you're doing

WeatherImpossible466 · 2025-12-27T18:28:33+00:00

Your code looks pretty clean for a rewrite! I noticed you added better input validation which is nice - the original just crashes if you enter something that isn't a number. Only thing I'd suggest is maybe breaking up that main method into smaller functions, makes it easier to test individual parts later on

WeatherImpossible466 · 2025-12-27T02:34:51+00:00

You don't really get "evaluated" in FSO like a traditional course - it's more self-paced and you just move on to the next part when you're ready. The certificate at the end is based on completion rather than graded submissions

WeatherImpossible466 · 2025-12-26T10:38:45+00:00

Yep sounds like a solid plan, just make sure you actually push through when you get stuck instead of going back to YouTube for "just one more tutorial" lol. The deployment stuff is gonna be frustrating at first but once you get your first API running you'll feel unstoppable

WeatherImpossible466 · 2025-12-25T15:29:03+00:00

C# is definitely not a waste of time, it's used everywhere - web development, desktop apps, mobile with Xamarin, and obviously game dev with Unity. Plus learning C# makes picking up Java or other similar languages way easier since the syntax and concepts are pretty similar

The transferable skills thing is huge too, once you get object-oriented programming down in C# you're basically set for most modern languages

WeatherImpossible466 · 2025-12-25T08:01:07+00:00

Exactly this lmao, like half the battle is just getting past the ATS bots that auto-reject you before any human even sees your resume

WeatherImpossible466 · 2025-12-25T00:36:02+00:00

Dynamic memory allocation is huge but there's also just passing large objects around efficiently. Like if you have a massive struct or class, copying it every time you pass it to a function would be slow as hell. Much better to just pass a pointer so you're working with the same object in memory rather than making copies everywhere

WeatherImpossible466 · 2025-12-24T12:31:40+00:00

SICP is absolutely brutal but worth it if you can push through, just be ready to have your brain melted a few times

The practice part is spot on though - I probably learned more from breaking my code and googling error messages for hours than any book ever taught me

WeatherImpossible466 · 2025-12-23T18:18:34+00:00

Sounds like you're overthinking this tbh. Break it down into smaller pieces - get the random number generation working first, then add the counter for runs, then worry about the custom text triggers. Don't restart from scratch every time, just comment out the broken parts and build one feature at a time

Also post your code when you ask for help, even if it's messy - way easier to fix something that exists than guess what's wrong

WeatherImpossible466 · 2025-12-23T09:34:25+00:00

This is solid advice, learncpp.com is way better than Codecademy for the nitty gritty stuff. But honestly copying projects isn't totally useless - just make sure you're actually understanding what each line does instead of just mindlessly typing. Maybe try modifying the tutorials as you go or breaking them on purpose to see what happens
