Alright @BenjDicken you’ve convinced me databases are cool.
I wanted to ingrain the fundamentals so so now I’ll be writing a poor man’s database in Rust.
I’ll try to post a weekly article documenting everything I’ve built.

“What man is he who, weighing his own weakness, dares to ascribe his purity and innocence to his own strength, so that he should love you the less, as if he had less needed your mercy, by which you forgive sins to those who turn to you?” - Augustine
he will never find Christianity again.
he is too far gone and his hedonist nihilism wont change unless he has a traumatic experience.
this guy is the final stage of nietzsches demonic worldview

Once you become Catholic, you realize the Protestant denominational differences are pretty meaningless, for they all share the same misguided foundation: that each individual can determine doctrinal truth on his own.

Do not be afraid to sow without immediately seeing the fruits. The sowing belongs to you; the growth belongs to God. No gesture carried out in the name of Christ is useless.

I watched this reel today where a random person came up and asked another person in a 5 minute conversation “What’s your TC”.
To believe this is the state of affairs right now is just sad. Another person is no longer a human being to be known or understood but somebody to be compared against.
The only conceivable this could be combatted when people make efforts to relearn what it means to be human. It starts with not automating interpersonal communication.

Very true. Intern here and saved my company 3M contract which a big company was trying to rip them off for.
Everybody is sleeping on the southeastern region right now.

The #GospelOfToday (Mt 14:22-33) teaches us the importance of not getting carried away by success and of never being presumptuous. At the same time, it teaches us not to despair, even in moments of darkness, when we feel powerless in the face of problems.

Webcodecs is insane. All of the media encoding and decoding and subtitle is happening in the browser.
I built this brainrot video generator just for fun and was using FFmpeg and it worked great, but deployment quickly became a hassle.
I had a canvas in the web already for live previews, but after seeing the post I tried to use MediaBunny and holy crap, it works like a charm. This is a first pass demo.
I need to make it more polished but this makes me even more bullish about @diffusionhq
Prolly going to dive deep and try to write a detailed analysis of how it is working!
The WebCodecs performance ceiling is honestly mind-blowing. Everything you're seeing here is running entirely in the browser.

I’m not sure why but AI writing makes my blood boil. It is ironic because I use AI more than 95% of the population just by the virtue of being a SWE.
There is something about connection and maybe even language itself. The point of social media was to imitate and enable real human connection for those who otherwise may not be able to. However, reading all these slop posts and writing seems as if the person behind the screen thinks of me as an engagement point to optimize for.
I am not able to articulate it properly as it is closer to midnight and I’m tired after a day of work but maybe I will try to write something about it.
On a similar note, I love @pangram! I love the modern witch hunting of AI sloppers!

maximize learning!!!
As I continue to write more software, it seems like software engineering is less and less of a solved problem. At the same time, I am not writing code by hand anymore. It is certainly a strange position to be in.
When I was a freshman in college, AI was already here but it was frowned upon to use it. The reasons given were that they would impede learning. Now, just three years later, it seems the use of AI is ubiquitous.
It seems that AI has completely changed learning. I have been trying to build more and it has allowed me to tackle way beyond what I know. The only way I have been growing and learning is continuously tackling new problems and going deep in it. It has to be very intentional and the desire to one shot and get some semi-working shitty prototype is more than ever. I have had to intentionally increase friction to allow myself the space to think as constant steering is still required for the agent and for that end, I need to know enough.
It seems it is easy to get to the 80% of the solution but further intentional refinement is what differentiates and scales. If I do not know a topic, I just continue to talk to the LLMs till I know how to. The way I keep the models in check is by constraining the models to specific requirements and using strict types. This is something I learnt from old man @badlogicgames
Here’s an aggregate of tips to maximize learning -

This iteration: added tests before I move onto the B+ trees.
I realized during tests that my write_at specific page can even update unallocated pages so had to fix that.
I will complete the testing of Disk Scheduler. Picked it back up since I was busy with internship :/
Week 3: Finally flushed out the error and starting the next phase - Slotted Pages and B+ Trees.
Right now your buffer pool deals in raw bytes. They have no way to:
- Insert a row
- Find row #3
- Delete row #2
- Know how much space is left
SlottedPage is the layer that gives those bytes meaning. It's the thing that knows "bytes 0-1 are free_start, bytes 2-3 are free_end, bytes 4-7 are slot 0, the tuple for slot 0 starts at offset 3800..."
So the buffer pool's job stays the same: move pages in and out of memory. SlottedPage's job is to interpret and mutate the contents of a page.
Currently: Mapping out the struct and methods for the slotted layer. This may need additional changes as when a page is created when we get the page_id, we need to populate it with header data.
This step is needed for the B+ tree as it stores the page_id and slot_id for the records.

If you’re early in your career maybe it’s helpful to hear that despite several decades leading large eng projects I still don’t really know what I’m doing. Every new project I’m still filled with that sense of “holy crap how do I solve this?” You always get better but if you’re doing your best work you’ll probably always be operating outside your comfort zone. Don’t be fooled into thinking we’ve all got it figured out, just figure out the smallest next step you can take towards solving that problem you thought was too hard.
