How the NYT Letter Boxed Puzzle Became My Daily Brain-Warmup

Hellen charless — Fri, 06 Mar 2026 09:40:27 +0000

If you enjoy logic puzzles, word games, or quick daily challenges, you’ve probably heard about Letter Boxed. It’s one of those deceptively simple puzzles that can easily become part of your daily routine.

I started playing it out of curiosity, and now it’s something I open almost every morning before diving into coding or writing.

What Is Letter Boxed?

The New York Times introduced Letter boxed online as part of its puzzle collection. The game presents 12 letters arranged around the four sides of a square, and the goal is to create a chain of words using all the letters in as few words as possible.

At first glance it looks easy—but the rules quickly make it interesting.

Core Rules

Words must be at least three letters long.

You cannot use two letters from the same side consecutively.

Each new word must start with the last letter of the previous word.

The puzzle is solved when all letters are used at least once.

Most players try to solve the puzzle using only two words, which is considered the “perfect” solution.

Why Developers Might Enjoy It

Even though it’s a word puzzle, it feels surprisingly similar to solving programming problems.

Here’s why:

Pattern Recognition

Just like debugging or optimizing code, success in Letter Boxed comes from spotting patterns in letters and predicting how they connect.

Constraint-Based Thinking

You’re constantly working within rules:

No same-side letters consecutively

Words must chain together

All letters must be used

This feels a lot like solving problems with strict constraints in algorithms.

Optimization Mindset

You can solve the puzzle with multiple words, but the real challenge is minimizing them.

That optimization challenge feels very similar to improving code efficiency.

A Small Strategy That Helped Me

A few tricks I learned after playing regularly:

Start by identifying rare letters like Q, X, or Z.

Look for letters that connect many sides (like E or S).

Think about the last letter of your first word, because it determines your next options.

Sometimes I spend more time planning the first word than actually typing it.

Why It’s a Great Daily Habit

Short puzzles like Letter Boxed help me:

warm up my brain before coding

expand vocabulary

improve pattern recognition

And the best part: each puzzle is different and resets daily, so it never gets repetitive.

Curious to Hear From Other Developers

Do you play any daily puzzles before coding?

Some developers swear by Sudoku, others by Wordle or crossword puzzles. Personally, Letter Boxed hits the sweet spot between logic and creativity.

Would love to hear what puzzles you use as your brain warm-up.

What Puzzle Games Like Letter Boxed Can Teach Us About UX in Web Apps

Hey folks! 👋

As developers, we often focus on performance, features, and best practices — but sometimes the most engaging experiences come from simple, playful interactions.

Recently, I was thinking about the word‑puzzle game Letter Boxed, where players connect letters around a box to form words. At first glance, it’s just another casual game — but the way it’s designed reveals a lot about user engagement and interaction design, especially for web apps.

Here are a few lessons I picked up that I think apply to web development:

🧠 1. Immediate Feedback is Powerful

In Letter Boxed, each letter you connect shows instantly, and the game visually reinforces progress. This reminds me how important it is for web apps to provide real‑time feedback — whether it’s form validation, loading indicators, or toast messages.

✨ 2. Small Rewards Keep Users Hooked

Every correct word feels like a mini victory. In apps, we can replicate this with subtle micro‑interactions — success messages, animations, or even UX patterns that reward completion.

🧩 3. Clear Rules, Minimal Friction

The game has very simple rules, yet meaningful challenge. Great web apps apply the same principle: clarity over complexity. Users shouldn’t need a manual to understand the flow.

📌 4. Progress Without Pressure

Letter Boxed encourages users to keep going without feeling overwhelmed. Similarly, good onboarding and progressive disclosure in apps help users feel in control.

Would love to hear your thoughts 👇

What I Learned Building a Real-Time Chat App With WebSockets in Go

Hellen charless — Wed, 04 Mar 2026 15:07:03 +0000

As developers, we often reach for the usual suspects — REST APIs, GraphQL, or third-party services — even when our app requirements lean toward real-time communication. A few months ago, I needed to build a simple chat server that updates instantly without polling, so I decided to explore WebSockets using Go (Golang).

In this post I’ll walk through:

What WebSockets are

How they differ from REST

A minimal Go implementation

What problems you might run into along the way

🔁 Why WebSockets?

Most HTTP-based APIs (including REST) are request/response — meaning the client asks, then the server replies. That works for many use cases, but not for:

Chat apps

Live dashboards

Real-time games

Collaborative tools

WebSockets, on the other hand, allow persistent bidirectional communication between client and server without repeated polling.

🚀 WebSockets in Go — Example Code

Here’s a basic WebSocket handler using the popular gorilla/websocket package:

package main

import (
"github.com/gorilla/websocket"
"net/http"
)

var upgrader = websocket.Upgrader{}

func wsHandler(w http.ResponseWriter, r *http.Request) {
conn, err := upgrader.Upgrade(w, r, nil)
if err != nil {
http.Error(w, "Could not upgrade", http.StatusBadRequest)
return
}
defer conn.Close()

for {
    // Read message from browser
    messageType, p, err := conn.ReadMessage()
    if err != nil {
        break
    }

    // Print and send back
    fmt.Printf("Received: %s\n", p)
    conn.WriteMessage(messageType, p)
}

}

func main() {
http.HandleFunc("/ws", wsHandler)
http.ListenAndServe(":8080", nil)
}

This simple server:

Upgrades an HTTP request to a WebSocket connection

Reads messages

Echoes them back to the client

Of course, you’ll want to expand this for:

Broadcasting to multiple users

Room/channel support

Better error handling

💡 Deployment Tips

Here are a few gotchas to watch out for:

Proxy & Load Balancer Support: Ensure your reverse proxy supports WebSockets (e.g., NGINX with proxy_http_version 1.1 and appropriate headers).

CORS Restrictions: If you’re calling from a browser, make sure your CORS settings allow WebSocket connections.

Heartbeat/Ping-Pong: Use ping/pong frames to prevent idle clients from being disconnected.

🧠 Final Thoughts

Using WebSockets in Go is a rewarding way to understand real-time protocols without the overhead of third-party services. You get:

✔ Better responsiveness
✔ Simpler architecture for interactive apps
✔ More efficient use of server resources

If you’re just starting with real-time apps, I’d encourage you to build a small prototype like this — it teaches a lot about the fundamentals.

Mastering the async-await Pattern in JavaScript (Beginner Intermediate Guide)

Hellen charless — Mon, 02 Mar 2026 15:33:09 +0000

Asynchronous JavaScript is powerful but confusing at first. Between callbacks, .then() chains, and Promises, it’s easy to get tangled. In this post I’ll walk you through how async / await works, why it matters, and how to avoid common pitfalls.

I wrote this because when I was learning Javascript async patterns, I spent way too much time debugging nested callbacks and mysterious race conditions. If you feel stuck sometimes — you’re not alone.

🧩 Why async-await?

Before async-await, writing asynchronous JavaScript looked like this:

fetch("/users/123")
.then(res => res.json())
.then(user => {
return fetch(/posts?user=${user.id});
})
.then(res => res.json())
.then(posts => {
console.log(posts);
})
.catch(err => {
console.error(err);
});

This works — but it chains complexity quickly as apps grow.

With async-await, your code starts to resemble synchronous logic:

async function getUserPosts(userId) {
try {
const userRes = await fetch(/users/${userId});
const user = await userRes.json();

const postsRes = await fetch(`/posts?user=${user.id}`);
const posts = await postsRes.json();

return posts;

} catch (error) {
console.error("Failed to fetch user posts:", error);
}
}

Boom — easier to read, easier to maintain.

🚀 How It Works

async functions always return a Promise. That means you can still compose them with .then(), or use await inside another async function.

async function printPosts() {
const posts = await getUserPosts(42);
console.log(posts);
}

printPosts();

Key points:

await pauses the function until the Promise fulfills.

If the Promise rejects, it throws an error that can be caught with try/catch.

You can’t use await at the top level without an async function (yet — top-level await is supported in modules).

📌 Common Mistakes & How to Avoid Them
❌ Missing await
const data = fetch("/data"); // Oops! data is a Promise
console.log(data);

Fix:

const data = await fetch("/data");
❌ Ignoring Errors

Without try/catch, a rejection will crash your app:

try {
const res = await fetch("/bad-url");
} catch (err) {
console.error("Request failed:", err);
}
💡 When Not to Use async-await

If your code needs to perform multiple independent Promises concurrently, use Promise.all():

await Promise.all([loadUsers(), loadPosts(), loadComments()]);

This fetches everything in parallel instead of in sequence, which can improve performance in many cases.

🧪 TL;DR

Use async-await for clearer async logic.

Always combine with try/catch for robust error handling.

For parallel operations, consider Promise.all().
