senior devs, i come with a question. i haven’t written python in like 2 weeks (been focused on sql) and it feels like i’ve forgotten some things. is this normal? should i be practicing daily? what’s the right approach?

what REALLY happens when you click “send” on a message? you don't know? then you're at the right place: (short thread)

and that’s basically what happens before you see “sent”. your simple “hi” might just finished an entire world tour before hitting your friend’s phone 😂 if you want more threads like this, let me know 🌚🖤

also: most apps use end-to-end encryption, so even though your message travels through many routers and servers, nobody can read it. without your private key, it looks like nonsense. a very smart kind of nonsense.

when it finally gets to the app’s servers, they check: is this person online? if yes it push the message immediately if no it store it temporarily until their device reconnects that’s why you sometimes open WhatsApp and BOOM and 10 messages drop at once.

then the part most people don’t know: your message doesn’t go directly to the person. it jumps through multiple devices: your phone → your router → your ISP → different routers → WhatsApp servers. the internet is just millions of connected computers routing stuff around.

next, your message gets packaged. the internet uses rules called protocols: IP → decides the destination TCP → makes sure nothing gets lost UDP → used for fast stuff like calls basically like writing an address and sealing an envelope.

first thing: your message becomes 1s and 0s. computers don’t understand english, only electrical signals. so “hey bro” turns into something like: 01101001 01101101 ... ugly, but that’s how computers talk.

honestly�� i’ve been wanting a real, physical friend again. someone you see often, move with, talk with, do life with. i had friends like that, but life moved all of us in different directions now we mostly just talk online. i guess i kind of miss the closeness.

lately i’ve been noticing something: once you really understand a concept (like when you can explain it simply or write it out) everything after that is just practice. the clarity comes first, the perfection comes from repetition.

today was somehow great. continued learning SQL, currently on lecture 3. learned about set operators and table variables, and practiced everything using this website:

Insecurity, Insecurity...I’m tired of just talking man As a Nigerian software engineer, I decided to try fixing it in my own way, so I built an App: Sentra Now before you scroll away, just give this a chance. Check the comments for how it works and let me know what you think
