Originally published on danholloran.me The original Grimicorn was an exercise in restraint: muted pastels on a blue-gray base, tuned so nothing on screen ever burns your eyes. Grimicorn Neon is the opposite impulse. Same grim-reaper-meets-unicorn idea, except this one is plugged into the mains — saturated, glowing accents on a near-black base, dark-only, loud on purpose. What makes the pair interesting from an engineering angle is how little had to change to get there. Neon is not a new theme so much as the same theme with the volume knob turned all the way up. That only works because of a decision made back in the calm version: colors are defined by role, not by appearance. Eight roles, eight louder hexes Both themes share the exact same role map. Blue is keywords, links, and the primary accent. Green is strings, success, and the cursor. Yellow is types, decorators, and warnings. The accent hierarchy is still blue → purple → teal, and the semantic anchors still hold: green means good, the error color means wrong. What changes is only the values bound to those roles. Calm Grimicorn's blue is a soft #83AFE5 ; Neon's is an electric #2323FF . Calm green is a sage #A9CE93 ; Neon green is an acid #A3E635 . The error role even swaps identity, from a gentle salmon to a hot #FF2D9B pink. Lay the two palettes side by side and the structure is identical — only the saturation and brightness move: // same eight roles, two personalities const calm = { blue : " #83AFE5 " , green : " #A9CE93 " , error : " #DD9787 " , base : " #253039 " , }; const neon = { blue : " #2323FF " , green : " #A3E635 " , error : " #FF2D9B " , base : " #0A0A0B " , }; Because every one of the fourteen tool ports — VS Code, Ghostty, Obsidian, Claude Code, JetBrains, tmux, and the rest — is generated from a single palette.md , producing the neon set was mostly a matter of feeding the build a different eight values. The emitters that translate roles into VS Code scopes or ANSI slots never knew the difference.

What happens when thousands of people decide they're hungry at the exact same time? The Quiet Before the Storm 10:00 PM. The numbers are gentle tonight. One hundred eighty-nine requests trickle in. Someone in Lagos is ordering late-night suya. A rider in Ibadan is wrapping up his last delivery. In Bangladesh, someone is just discovering us for the first time. By 11:00 PM , things get quiet. Just 8 requests. The platform takes a breath. 2:00 AM. A mystery. 151 requests spike out of nowhere. We check the logs. Nothing unusual. Just a group of night owls ordering food, maybe shift workers, maybe students pulling an all-nighter. The beauty of a platform is we're always on, always ready. 7:00 AM. Good morning, Nigeria. Fifty-five requests. People waking up, checking their wallets, planning their day. The coffee hasn't even brewed yet, but the platform is already humming. The Morning Rush 9:00 AM. 315 requests. The workday begins. Offices buzz with conversations about lunch plans. If someone searches "foodmat site" for the third time this week, they're getting closer to finding us. A corporate client logs in to set up their employee meal program for the first time. By 10:00 AM , the traffic settles to 50 requests. A calm before the real storm. 11:00 AM. 173 requests. The hunger is building. People are making decisions about what to eat, where to order, and which vendor to choose. Our World Cup campaign notifications ping. Someone shares their referral code. The viral loop begins. The Lunch Explosion 12:00 PM. 321 requests. It's happening. The platform comes alive. 1:00 PM. 339 requests. The peak is building. Our servers are handling it smoothly. This is where the magic happens when thousands of people decide they're hungry at the exact same time. 2:00 PM. 289 requests. Still going strong. Vendor dashboards refresh. Riders accept orders. Laundry bookings come in alongside food deliveries. If someone cancels an order with a reason, we take note. Every interaction teaches us

"Prop drilling is bad, use Context" is repeated everywhere — but the actual cost stays abstract. So I put the two approaches side by side with live render counters. Click one button and the difference is impossible to miss. ▶ Live demo: https://context-vs-props-drilling.vercel.app/ Source (React 19 + TS): https://github.com/dev48v/context-vs-props-drilling Two identical 4-level trees, both React.memo 'd. One threads a value down as a prop through every level; the other provides it once via Context and reads it only at the leaf. Change the value: Prop drilling → 4 components re-render. Every component on the path receives the changed prop, so all of them re-render — and each intermediate is cluttered with a value it does nothing with except pass along. Context → 1 component re-renders. The intermediates take no value prop, so they're skipped (memoized, props unchanged). Only the consumer leaf re-renders. The summary tallies it on every click: 4 vs 1 . Why Context skips the middle This is the part that surprises people: with Context, an intermediate component can be skipped even though a descendant re-renders . < ThemeCtx . Provider value = { val } > < A /> { /* memo, no props → skipped on value change */ } </ ThemeCtx . Provider > const A = memo (() => < B />); // skipped const B = memo (() => < C />); // skipped const C = memo (() => < Leaf />); // skipped const Leaf = () => { const value = useContext ( ThemeCtx ); // ← re-renders on context change return < div > { value } </ div >; }; React re-renders context consumers directly when the provider value changes — it doesn't need to re-render the components in between. With prop drilling there's no such shortcut: the only way the value reaches the leaf is through every parent, so every parent must re-render. The catch — Context isn't a free lunch Context isn't a "no re-renders" button. Every consumer re-renders whenever the provider value changes — there's no built-in selective subscription. One big, chatty context ca

I am committed to understand how systems actually work. I'm working on a multi-node lab to follow the complete path of a request from Python APIs to Linux processes, through Docker containers, networking and observability. The idea is simple: build a system that observes another system to understand the abstraction layers behind modern infrastructure. This project is about learning by building, experimenting and understanding what happens under the hood.

Bash4LLM is a single-file Bash wrapper for interacting with LLMs from the terminal. I created it because I wanted something simple that worked without installing Python, Node, or any other runtime. It uses only Bash, curl, and jq. You can send prompts, start a small chat, process files line by line, stream output, and save session metadata in JSON format. I tried to make it safe and predictable: no use of the system /tmp, no use of eval. Groq is supported by default, and other providers can be a
