Founder @ a telegram bot that lets you build landing pages and start collecting leads directly in telegram!

We spend $0.001 to decide if we need to spend $0.08.
A cheap Haiku call gates every edit before it reaches our $0.05-0.10 Sonnet call. Fails open too, a broken gate should never block a paying user.

How are other agentic builders solving this?

Shopify stores don't break at 10k SKUs because of scale.

They break because options are coupled to products.

5 colors × 4 sizes × 2 materials = 40 variants per product.

Fix: Modularity + Hierarchy + Constraint

One change, not 300.

A flip-flop is 2 NOR gates wired so each output feeds back into the other's input.

S=1 → locks to 1
R=1 → locks to 0
Both 0 → holds last value forever

This is 1 bit of memory.

Stack millions → RAM.

Two gates. A loop. The foundation of memory. #coding #buildinpublic

Three inventions. One idea. A switch that says yes or no.

That's the entire history of computing.

The relay was invented in 1835 for one reason: telegraph signals died over long distances.

The transistor fixed it in 1947. Same logic gate, solid-state - no heat, no filament, no glass. Small enough to fit billions on a fingernail.

[Filip Rastovic @rastovicfilip]

The catch: it filled an entire room. Consumed 150 kilowatts. Tubes burned out constantly.

[Filip Rastovic @rastovicfilip]

When it clicked, engineers built computers from vacuum tubes. ENIAC (1945) had 18,000 of them. Combinations of tubes formed logic gates. Those gates built circuits that solved in seconds what took humans days.

[Filip Rastovic @rastovicfilip]

Nobody connected that to logic. Boolean algebra came in 1854. The idea that on/off = AND, OR, NOT took another 80 years to link together.

[Filip Rastovic @rastovicfilip]

The fix was elegant. Weak current → electromagnet → flips a switch → fresh full-strength signal forward. On or off. That's it.

[Filip Rastovic @rastovicfilip]

Currently reading CODE by Charles Petzold.

The logic behind telegraphs and relays is the core of every modern computer.

A relay: weak current in → magnet flips arm → strong signal out. On or off.

That became logic gates. Gates became CPUs. CPUs became everything.
