How I reclaimed 47GB on my MacBook by cleaning developer project junk

Last week I ran out of disk space mid-deploy. That annoying “Your startup disk is almost full” notification. I had a 512GB MacBook and somehow had less than 8GB free.

So I started digging. What I found surprised me.

The culprits

Here’s the breakdown of what was eating my storage:

node_modules — 18GB

Every JavaScript project has one. They’re never small. A typical React project pulls in 300–500MB of dependencies. I had projects from 2021 I’d completely forgotten about — each one with an intact node_modules folder taking up space.

The good news: they’re completely safe to delete. npm install (or yarn, or pnpm) regenerates them instantly.

Unity Library folders — 14GB

If you’ve ever used Unity — even just for a game jam or a tutorial — your project has a Library folder. Unity uses it as a local cache for imported assets. It regenerates automatically when you open the project.

I found four old game jam projects I’d abandoned. Combined Library size: 14GB.

Xcode DerivedData — 9GB

Xcode stores build artifacts, indexes, and intermediate files in ~/Library/Developer/Xcode/DerivedData. It grows silently over time. Mine had build caches from apps I no longer maintain.

Safe to delete via Xcode → Preferences → Locations → DerivedData → arrow button. Or just nuke the folder directly.

Python virtualenvs — 6GB

Every python -m venv or conda create leaves behind an isolated environment with its own Python installation and packages. I had virtualenvs from tutorial projects dating back to 2020.

The fix

I went through each category manually this time. It took about 40 minutes and recovered 47GB.

After doing this, I built a tool to make it automatic: PolySweeper. It scans your Mac, finds all of these by category, shows the size, and lets you delete with a confirmation step. Runs fully offline — nothing leaves your machine.

If you want to do it manually, here’s the quick version:

# Find largest node_modules folders
find ~ -name "node_modules" -type d -prune | xargs du -sh | sort -hr | head -20

# Find Unity Library folders
find ~ -name "Library" -type d -path "*/Assets/../Library" | xargs du -sh 2>/dev/null

# Clear Xcode DerivedData
rm -rf ~/Library/Developer/Xcode/DerivedData

Worth running even if you think your disk is fine. Most developers I know have 10–40GB hiding in these folders.

If you want the automated version: PolySweeper — macOS disk cleaner built specifically for developers. One-time $14.99.

Operators Are Not Oracles: How We Learned to Stop Worrying and Love the Configuration

The Problem We Were Actually Solving

We’ve all been there – staring at a production server that’s suddenly, inexplicably slow. As an engineer, I was tasked with identifying the root cause of our new Veltrix-based search engine, which was handling a massive surge in requests without warning. Weeks of analysis led us to a single, seemingly innocuous configuration parameter: the “delta window” setting in our Solr cluster config. It was set to 5 minutes, which seemed reasonable at first glance. However, as the server load increased, the search results began to return with wildly inconsistent latency – sometimes taking seconds to return, other times taking orders of magnitude longer.

What We Tried First (And Why It Failed)

Our initial attempt at solving this problem involved tweaking the delta window setting to a smaller interval, thinking that more frequent index updates would yield better results. However, this change led to performance degradation across the board, with Solr’s memory usage skyrocketing and the cluster eventually becoming unresponsive. It turned out that the delta window tweak was simply shifting the bottleneck elsewhere in the system, and our server was now taking on the additional overhead of more frequent indexing attempts.

The Architecture Decision

After weeks of trial and error, our team landed on a more nuanced approach to configuring the delta window setting. We developed a custom script that takes into account our server load, system memory, and the current state of the Solr index. The script makes real-time adjustments to the delta window setting, effectively throttling back indexing attempts during periods of high demand and low memory availability. This approach paid off in spades – we reduced average query latency by 75% while maintaining a smooth, responsive user experience.

What The Numbers Said After

The metrics told a compelling story. With our new architecture in place, we saw a 45% reduction in Solr indexing attempts, a 28% decrease in total system memory usage, and a corresponding 37% increase in search query throughput. Meanwhile, end-users reported fewer instances of slow or unresponsive search results. Perhaps most impressively, our custom script has allowed us to scale the search engine to handle 50% more concurrent requests without any notable performance degradation.

What I Would Do Differently

In retrospect, I would have approached this problem with a more nuanced understanding of the trade-offs involved with different delta window settings. Our team ultimately relied on a combination of experience, experimentation, and careful metrics analysis to arrive at a solution, but I’ve since come to realize the importance of formal modeling and simulation techniques in these situations. By leveraging statistical modeling tools like Apache Commons Math to forecast Solr’s behavior under different load conditions, we could have identified the optimal delta window setting with greater accuracy and confidence.

It’s a hard lesson to learn, but just as operators are not oracles, neither are our initial intuition nor the initial results of a simple tweak. Effective engineering requires taking the time to understand the complex systems we’re building, and to approach problems with a willingness to dig in and get our hands dirty.

I Built 6 Free Developer Tools for AI APIs, Cron, Docker, and Self-Hosting

I keep running into the same friction points: “How much will this prompt cost on GPT-4o vs Claude?”, “What’s the cron syntax for every Monday at 9am?”, “Is there an open-source alternative to Notion I can self-host?”

I got tired of Googling each time, so I built a set of free tools that solve these problems. No login, no API keys, no tracking — everything runs in your browser.

Here’s what each one does.

1. AI Prompt Cost Calculator

Paste any prompt and instantly see the cost across 10 AI models: GPT-4o, GPT-4o Mini, o3, o4-mini, Claude Sonnet 4, Claude Haiku 4, Gemini 2.5 Pro, Gemini 2.5 Flash, Llama 4 Maverick (via Groq), and DeepSeek R1.

It uses tiktoken for exact OpenAI token counts and estimates for other models (~4 chars/token for English, ~1.5 for Chinese). You can adjust monthly call volume and expected output tokens to see projected monthly costs.

Try it: AI Prompt Cost Calculator

2. Cron Expression Generator

161 cron expressions covering every common pattern. Each one comes with a plain-English explanation and the next 5 run times.

Some examples:

  • */5 * * * * — Every 5 minutes
  • 0 * * * * — Every hour
  • 0 9 * * 1 — Every Monday at 9:00 AM
  • 0 0 1 * * — First day of every month

There’s also a builder mode where you select the schedule and it generates the expression for you.

Try it: Cron Expression Generator

3. Self-Hosted Alternatives

36 popular SaaS tools, each with open-source alternatives you can self-host. Some examples:

SaaS Self-Hosted Alternative
Slack Mattermost
Notion Outline
Google Drive Nextcloud
1Password Vaultwarden
Trello WeKan
Zoom Jitsi Meet

Each alternative has a feature comparison and a link to its Docker deployment config (see tool #4).

Try it: Self-Hosted Alternatives

4. Docker Deploy Generator

One-click Docker Compose configs for 30 self-hosted applications. Copy, edit the environment variables, and run docker compose up -d.

Each config includes:

  • The official Docker image
  • Persistent volume mounts
  • Common environment variables with sensible defaults
  • Port mappings

Try it: Docker Deploy Generator

5. Voice AI Pricing Calculator

Compare TTS (text-to-speech) and STT (speech-to-text) pricing across 6 providers: OpenAI, ElevenLabs, Deepgram, AssemblyAI, Google Cloud, and Azure.

Enter your expected monthly character volume and see costs for each provider side by side. There are also preset buttons for common volumes (100K, 1M, 5M, 10M characters/month).

This was born out of my own frustration trying to compare voice AI pricing — each provider uses different pricing units (per character, per 15 seconds, per minute) making direct comparison painful.

6. AI Agent Safety Checklist

18 items across 8 categories for anyone building production AI agents:

  • Input validation
  • Tool & API security
  • Prompt injection defense
  • Data privacy
  • Access control
  • Monitoring & logging
  • Error handling
  • Supply chain security

Each item has a severity level (critical/warning/info) and an explanation of why it matters. Check items off as you go — your progress is saved in localStorage.

Try it: AI Agent Safety Checklist

Tech Stack

All 6 tools are static React apps built with Vite and Tailwind CSS. No backend, no database, no user accounts. Everything runs client-side.

The entire collection lives at prompt-cost-calculator-ten.vercel.app with 240 pages total (mostly from the cron generator and its long-tail expressions).

What’s Next

I’m working on:

  • Batch prompt cost calculation (upload a CSV)
  • More voice AI providers
  • i18n for the cron generator (Chinese and Japanese)

How I Built a Real-Time Precious Metals Price Feed for 30,000 Concurrent Users in Laravel

How I Built a Real-Time Precious Metals Price Feed for 30,000 Concurrent Users in Laravel

Architecture walkthrough: Laravel Reverb, WebSocket broadcasting, Redis pub/sub, and the tricks that make it hold under real load.

The Problem

A live precious metals trading platform needs to push gold and silver price updates to every connected user the moment a tick arrives — not every 5 seconds via polling, not via a REST endpoint they hammer on a timer. Real-time. Sub-second latency. And it needs to handle 30,000 simultaneous connections without melting.

This post walks through exactly how I built this using Laravel 11, Laravel Reverb, Redis, and a few architectural decisions that made the difference between a demo and something production-ready.

Stack

  • Laravel 11 + PHP 8.2
  • Laravel Reverb — self-hosted WebSocket server (replaces Pusher)
  • Laravel Echo — frontend WebSocket client
  • Redis — pub/sub backbone + cache
  • Laravel Horizon — queue worker monitoring
  • MySQL 8 — OHLCV candle storage with covering indexes

Full source: github.com/Hafiz-M-Subhan/laravel-precious-metals-platform

Architecture Overview

Price Feed (external API)
        ↓
  PriceService::ingestTick()
        ↓
  DB update + Redis cache (5s TTL)
        ↓
  broadcast(new PriceUpdated($asset))
        ↓
  Laravel Reverb (WebSocket server)
        ↓
  prices.XAU channel → 30k subscribers

The key insight: the database is not in the hot path for subscribers. Price data flows through Redis and directly out via WebSocket. The DB only gets written once per tick, not read 30,000 times.

Step 1 — The Event

The PriceUpdated event is what gets broadcast. The most important decisions are:

Which channel? Public, so unauthenticated visitors on the live page receive ticks too.

What payload? As small as possible. Every extra byte is multiplied by 30,000.

class PriceUpdated implements ShouldBroadcast
{
    public function broadcastOn(): array
    {
        return [
            new Channel("prices.{$this->asset->symbol}"),
            new PresenceChannel('live-event'), // carries viewer count
        ];
    }

    public function broadcastWith(): array
    {
        // 7 fields — deliberately minimal
        return [
            'symbol'     => $this->asset->symbol,
            'spot'       => (float) $this->asset->spot_price,
            'bid'        => (float) $this->asset->bid_price,
            'ask'        => (float) $this->asset->ask_price,
            'change_pct' => (float) $this->asset->daily_change_pct,
            'direction'  => $this->asset->spot_price > $this->previousPrice ? 'up' : 'down',
            'ts'         => now()->toIso8601String(),
        ];
    }

    // Skip broadcast if price moved less than 0.001% — kills ~80% of noise
    public function broadcastWhen(): bool
    {
        if ($this->previousPrice == 0) return true;
        $change = abs(($this->asset->spot_price - $this->previousPrice) / $this->previousPrice);
        return $change >= 0.00001;
    }
}

The broadcastWhen() gate is underused in most Laravel projects. In a metals feed, prices sometimes tick the same value repeatedly. Without filtering, you’re broadcasting thousands of no-op messages to 30,000 clients. With it, you cut ~80% of queue messages.

Step 2 — The WebSocket Server (Laravel Reverb)

Laravel Reverb is Laravel’s official self-hosted WebSocket server, released in 2024. Before Reverb, you either paid for Pusher or ran a separate Node.js server (Soketi, etc.). Reverb runs as a native PHP process:

php artisan reverb:start --host=0.0.0.0 --port=8080

In config/broadcasting.php:

'reverb' => [
    'driver'  => 'reverb',
    'app_id'  => env('REVERB_APP_ID'),
    'app_key' => env('REVERB_APP_KEY'),
    'app_secret' => env('REVERB_APP_SECRET'),
    'options' => [
        'host' => env('REVERB_HOST', '0.0.0.0'),
        'port' => env('REVERB_PORT', 8080),
        'scheme' => env('REVERB_SCHEME', 'http'),
    ],
],

Reverb uses a non-blocking event loop under the hood (ReactPHP). It handles thousands of concurrent connections on a single process — no thread-per-connection model like traditional PHP.

Step 3 — Redis as the Backbone

Redis does two jobs here:

1. Price cache — every tick writes to Redis with a 5-second TTL. API responses read from Redis, not MySQL. Under a burst of requests (live event with 30k viewers all hitting /api/v1/assets), the DB sees exactly 0 extra reads.

// PriceService::ingestTick()
Cache::put("asset:price:{$symbol}", [
    'spot' => $spot, 'bid' => $bid, 'ask' => $ask,
    'ts'   => now()->toIso8601String(),
], 5); // 5 seconds

2. Queue backend — the broadcast job goes through Redis queues, not the database. This is critical. QUEUE_CONNECTION=redis in .env. Database queues serialize and will struggle under a price feed that fires every 2 seconds across 4 metals.

Horizon monitors all of this with a real dashboard at /horizon. You can see queue throughput, failed jobs, and worker load in real time.

Step 4 — OHLCV Candle Storage

Every tick needs to update the current 1-minute candle (open, high, low, close). Naive approach: SELECT + UPDATE. At 30 ticks/minute across 4 metals, that’s 120 roundtrips per minute, plus locking issues.

Better approach: upsert() — one query, atomic, no SELECT needed:

PriceHistory::upsert(
    [[
        'asset_id'    => $assetId,
        'resolution'  => '1m',
        'open'        => $price,  // only set on INSERT
        'high'        => $price,
        'low'         => $price,
        'close'       => $price,
        'volume'      => 0,
        'recorded_at' => now()->startOfMinute(),
    ]],
    uniqueBy: ['asset_id', 'resolution', 'recorded_at'],
    update: [
        'high'  => DB::raw("GREATEST(high, {$price})"),
        'low'   => DB::raw("LEAST(low, {$price})"),
        'close' => $price,
    ],
);

The unique index on (asset_id, resolution, recorded_at) makes this both fast and idempotent — if the same tick somehow arrives twice, nothing breaks.

Step 5 — The Frontend (Laravel Echo)

import Echo from 'laravel-echo';
import Pusher from 'pusher-js'; // Echo uses Pusher protocol even with Reverb

window.Pusher = Pusher;

const echo = new Echo({
    broadcaster: 'reverb',
    key: import.meta.env.VITE_REVERB_APP_KEY,
    wsHost: import.meta.env.VITE_REVERB_HOST,
    wsPort: import.meta.env.VITE_REVERB_PORT,
    forceTLS: false,
    enabledTransports: ['ws', 'wss'],
});

// Subscribe to gold price updates
echo.channel('prices.XAU')
    .listen('.price.updated', (data) => {
        updatePriceTicker(data.symbol, data.spot, data.direction);
    });

// Presence channel — get viewer count for live event page
echo.join('live-event')
    .here((users) => setViewerCount(users.length))
    .joining(() => setViewerCount(prev => prev + 1))
    .leaving(() => setViewerCount(prev => prev - 1));

The presence channel gives you live viewer count for free — the same mechanism Kettner uses for their live event page that peaks at 30,000 simultaneous viewers.

Performance Numbers

Scenario Without optimization With optimization
API under burst (1k req/s) MySQL: 1000 reads/s MySQL: ~0 reads (Redis cache)
Queue messages per minute ~120 raw ticks ~25 (broadcastWhen filters)
Candle upserts 2 queries (SELECT+UPDATE) 1 query (upsert)
Connection overhead 30k × polling interval 1 persistent connection per user

Running It Locally

git clone https://github.com/Hafiz-M-Subhan/laravel-precious-metals-platform.git
cd laravel-precious-metals-platform
docker compose up -d          # MySQL + Redis + Elasticsearch + Reverb + Horizon
php artisan migrate --seed
php artisan reverb:start
php artisan horizon
php artisan prices:simulate --interval=2  # simulates live price feed

The simulator uses Geometric Brownian Motion to generate realistic price movements — the same model used in Black-Scholes options pricing.

What I’d Do Differently at True Scale

  1. Horizontal Reverb scaling — multiple Reverb nodes behind a load balancer, using Redis pub/sub to sync broadcasts across nodes
  2. Separate read replicas for candle chart queries — OHLCV history doesn’t need the primary DB
  3. Message compression — at 30k subscribers, gzip on WebSocket frames saves significant bandwidth
  4. Backpressure handling — slow consumers should be detected and disconnected before they cause memory pressure on the Reverb process

How to Use a SERP API to Validate Whether a Project Idea Is Worth Building

You may have an idea: building an AI resume builder, a PDF tool site, a small SaaS product, a content site, an affiliate site, a niche directory, or even a local service website. The first question is simple: is this direction actually worth building?

Many people judge by instinct: this niche seems popular, there seem to be many existing sites, and users probably need it. But before you start building, a more reliable approach is to look at search results. Search results already contain user demand, page types, content formats, and commercial signals.

This article walks through a complete workflow: starting from a project idea, using the TalorData SERP API to collect real search results, turning those results into tables, and then deciding whether the direction has an opportunity.

We will use AI Resume Builder as the example. The same method can also be applied to tool sites, SaaS products, content sites, affiliate sites, directories, and local service websites.

What You Will Get at the End

By following this article, you will produce three tables:

  • Keyword candidate table: turn a project idea into a set of searchable keywords.
  • SERP result table: use the SERP API to check each keyword and collect ranking pages, PAA, ads, domains, and other useful signals.
  • Opportunity decision table: use simple rules to decide which keywords are worth targeting and which ones should be postponed or avoided.

At the end, you should be able to answer three questions:

  • Is there real search demand for this direction?
  • Which sites are already ranking in search results?
  • If I build this now, which keyword or feature should I start with?

Step 1: Turn the Idea into Searchable Keywords

Let’s start with a concrete idea: I want to build an AI Resume Builder.

This idea is still too broad. You cannot judge the whole project with only one phrase, because a project usually contains many different user needs. Some users want a free tool. Some want an online resume builder. Some want a cover letter generator. Some only need a resume summary generator.

So the first step is not writing code or calling an API. The first step is turning the idea into search queries that real users might type into Google.

Step 2: Where the Keywords Come From

Keywords should not be guessed randomly. You can get the first batch from several sources.

1. Break Down the Core Features

For an AI Resume Builder, you can start with the core features:

  • Resume generation: ai resume builder
  • Online resume tool: resume builder online
  • Free resume tool: free resume builder
  • Resume summary generation: resume summary generator
  • Cover letter generation: cover letter generator
  • Resume bullet point generation: resume bullet point generator

2. Expand with User Modifiers

When users search for tools, they often add modifiers such as:

  • best, for example best resume builder
  • free, for example free resume builder
  • online, for example resume builder online
  • generator, for example resume summary generator
  • template, for example resume template
  • alternative, for example zety alternative

3. Add Keywords from Search Suggestions and Existing Pages

You can also expand keywords from Google autocomplete, People Also Ask, existing page titles, and discussions on Reddit or Quora.

If you do not know where to start, you can use ChatGPT to generate an initial keyword list, then use a SERP API to verify whether those keywords actually have search results and ranking pages.

Step 3: Create keywords.csv

Put the keywords into a CSV file. Keep the first version simple, with only one column: keyword.

keyword
ai resume builder
resume builder online
free resume builder
resume summary generator
cover letter generator
resume bullet point generator
ai cover letter generator
best resume builder

If you are testing a different project, just replace this column. For example:

  • PDF tool site: pdf compressor online, merge pdf online, pdf to word converter
  • SaaS: email verification API, invoice software, booking software
  • Content site: best dog food for puppies, how to train a puppy
  • Local service site: plumber near me, emergency dentist near me

Step 4: Query Keywords with the TalorData SERP API

Next, send one SERP API request for each keyword. You can register a TalorData account and get an API key with free credits from the official website.

Keep in mind that API requests consume quota. In general, one keyword means at least one request. If you prepare 20 keywords, the test will use around 20 requests. Before expanding the test, start with 5-10 keywords to make sure the workflow works.

The basic TalorData request format looks like this:

curl -X POST 'https://serpapi.talordata.net/serp/v1/request' 
  -H 'Authorization: Bearer YOUR_TALORDATA_API_KEY' 
  -H 'Content-Type: application/x-www-form-urlencoded' 
  -d 'engine=google' 
  -d 'q=ai resume builder' 
  -d 'json=2'

This request returns Google SERP data for the keyword. For decision-making, we mainly care about these fields:

  • organic results: natural search results, used to see who ranks at the top.
  • People Also Ask: user questions, used to identify content opportunities.
  • ads: advertising results, if available, used to estimate commercial value.
  • titles and URLs: used to understand page types.
  • domains: used to identify and count the sites that appear in search results.

Step 5: Run the Script and Generate the Result Table

The script reads keywords.csv, queries the TalorData SERP API, and outputs two files:

  • serp_opportunities.csv: the analysis table used for judging opportunities.
  • serp_raw_records.jsonl: the raw crawl records, useful for checking how each conclusion was produced.

In the main article, we only show the key part of the code:

TALORDATA_API_KEY = "YOUR_TALORDATA_API_KEY_HERE"
ENDPOINT = "https://serpapi.talordata.net/serp/v1/request"

headers = {
    "Authorization": f"Bearer {TALORDATA_API_KEY}",
    "Content-Type": "application/x-www-form-urlencoded",
    "User-Agent": "curl/8.0.0",
}

data = {
    "engine": "google",
    "q": keyword,
    "json": "2",
}

response = requests.post(ENDPOINT, headers=headers, data=data, timeout=60)
response.raise_for_status()
result = response.json()

This is the part that sends a keyword to TalorData and receives the SERP response. The full script is included at the end of the article.

Step 6: Look at the Result Table Before Judging the Opportunity

The script will produce a table similar to this:

keyword organic_count paa_count ads_present top_domains Initial read
ai resume builder 10 4 true resume.io, resumegenius.com, enhancv.com Demand is clear, but competition is strong
free resume builder 10 5 true canva.com, zety.com, resume.com Strong free-tool demand and obvious commercial competition
resume summary generator 9 6 false tealhq.com, resumeworded.com, kickresume.com Better long-tail opportunity
cover letter generator 10 4 true grammarly.com, resumegenius.com, zety.com Suitable as a feature page entry point

This table is your first project opportunity map. It shows demand strength, ranking-site patterns, and commercial signals behind each keyword.

Step 7: How to Decide Whether a Signal Is Strong or Weak

When judging opportunities, avoid vague words like “many”, “few”, “strong”, or “weak”. Use simple rules instead.

Signal How to Judge What It Means
PAA >= 4 Many questions Rich user needs; suitable for content pages or FAQ
PAA 1-3 Some questions Some content opportunity
PAA = 0 Few questions Limited room for content expansion
ads_present = true Ads exist The keyword may have commercial value
Top 10 has 2+ small sites Better new-site opportunity The SERP is not fully dominated by major brands
Top 10 is almost all major sites Strong competition New sites should avoid attacking the core keyword directly

Here, major sites mean strong brands, platforms, or high-authority websites, such as Canva, LinkedIn, Indeed, HubSpot, Forbes, and Wikipedia.

Small sites usually mean niche tool sites, small SaaS products, personal blogs, niche content sites, or emerging product sites.

You should also keep clear “give up” signals. If almost every keyword has a Top 10 dominated by major sites, very few PAA questions, no ads, and no small sites ranking, the direction may have weak demand or may already be heavily monopolized. In that case, do not force the conclusion that it is still worth doing. A better move is to switch to a more specific keyword or choose another direction.

Step 8: Turn the Result into a Conclusion

Now let’s go back to the AI Resume Builder example. Based on the sample results, we can make these judgments:

  • ai resume builder: strong demand, but also strong competition. It is not a good first breakthrough keyword.
  • free resume builder: high traffic and commercial value, but many major brands compete for it.
  • resume summary generator: more specific, with many PAA questions, suitable as an early entry point.
  • cover letter generator: clear demand, suitable as a second feature page.

So the direction is not “not worth doing”. The real conclusion is: do not start by attacking the hardest core keyword. A more practical starting point is to build specific feature pages first, then expand toward the main tool page.

Step 9: Create Your Opportunity Decision Table

Finally, convert each keyword into a clear decision.

keyword Opportunity Level Suggested Action
ai resume builder Medium Treat it as a long-term target, not the first keyword to attack
free resume builder Medium Has traffic and commercial value, but needs differentiation
resume summary generator High Suitable as one of the first feature pages
cover letter generator High Suitable as a feature expansion page
best resume builder Medium-low Better for later comparison content

The goal is not to produce an absolutely correct answer. The goal is to decide where to put resources first: which pages to build now, which keywords to postpone, and which directions are not worth continuing.

Optional: Turn the Rules into a Simple Score

If you want more automation, you can turn the rules from Step 7 into a simple scoring function. This lets the script output an initial score for each keyword.

def score_keyword(paa_count, ads_present, big_site_count, small_site_count):
    score = 0

    if paa_count >= 4:
        score += 2
    elif paa_count >= 1:
        score += 1

    if ads_present:
        score += 2

    if small_site_count >= 2:
        score += 2

    if big_site_count >= 4:
        score -= 2

    if score >= 4:
        return "High"
    if score >= 2:
        return "Medium"
    return "Low"

This score should not replace human judgment, but it can help you quickly identify which keywords deserve attention first.

Step 10: Apply the Method to Your Own Project

This method can be reused across many project types. You only need to replace the keywords.

Project Type Example Keyword What You Can Validate
Tool site pdf compressor online Tool demand, existing tools, free/paid opportunity
SaaS email verification API Commercial intent, SaaS sites, pricing-page competition
Content site best dog food for puppies Content opportunity, PAA questions, affiliate opportunity
Directory site best AI tools for students Listicle opportunity and existing directory sites
Local service site plumber near me Local competition, local pack, service provider rankings

The general workflow is:

Project idea -> Find keywords -> Query with TalorData SERP API -> Get result table -> Judge opportunity by rules -> Decide whether to build and where to start

Conclusion

A project direction should not be judged only by instinct. You need to look at real search results to understand demand, commercial value, existing ranking sites, and possible entry points.

The value of a SERP API is that it turns Google search results into data you can analyze in batches.

For a new project, the best direction is not always the most popular one. A better direction is one with search demand, commercial value, room for content or feature expansion, and a realistic entry point for a new site.

If you already have an idea, start with 5-10 keywords and run this workflow once. You will have a much clearer view of whether the direction is worth building and where your first step should be.

Designing an In-Game Inflation Tracking Algorithm for Web Utility Apps

In modern web development, scaling an application to track real-time transactional data presents unique hurdles especially when tracking hyper-volatile secondary market economies like the Blox Fruits Easter Update.

Traditional gaming utility sites rely on static JSON tables or manual content management updates. The fatal flaw here is a structural 48-to-72-hour data lag. In a market where server updates shift item demand in minutes, static lists cause users to make highly unfavorable trades.

To combat this, we developed a responsive computing framework for our production node at the Blox Fruits Value Calculator, which processes algorithmic demand weights rather than raw, unchanging price points.

The Mathematical Framework of Demand Scaling

To calculate true market parity, an algorithm cannot look at an item’s hardcoded “Beli” store cost alone. It must evaluate an item’s real-time transactional velocity ($V$) against its current active circulation ($C$).

We structure our calculations using a baseline multipliers approach:

$$M_v = frac{V_t cdot alpha}{C_s cdot beta}$$

Where:

  • $M_v$ represents the dynamic velocity multiplier.
  • $V_t$ is the volume of logged trade attempts in a rolling 60-minute window.
  • $C_s$ represents known item liquidity based on drop rates.
  • $alpha$ and $beta$ are normalization constants adjusted during server events.

For developers interested in inspecting how these arrays are set up on the backend, you can review our open-source structural schema inside this Raw JSON Data Repository on GitLab.

Mitigating Front-End Calculation Lag

When dealing with massive traffic surges during event periods, running complex database queries on every user interaction will crash standard serverless instances.

To achieve optimal performance, we implemented a localized calculation engine:

  1. The server caches the macro-level $M_v$ multipliers globally every 5 minutes.
  2. The user’s browser executes the raw trade comparison equations locally using a lightweight JavaScript architecture.
  3. This decouples database read operations from user input, reducing server response times down to sub-10ms.

We initially mapped this UI layout within an open interactive sandbox environment, which you can view in our production-ready CodePen UI Sandbox Prototype.

Conclusion

Building software for gaming communities requires the same structural integrity as traditional SaaS applications. By moving away from static database rows and moving toward algorithmic, cached calculations, you can scale a lightweight utility site to handle millions of active users with minimal overhead.

Google AI Studio Just Changed the Shape of App Development

This is a submission for the Google I/O Writing Challenge

The browser is becoming the IDE, the backend, the deployment pipeline and the App factory

The most important thing Google announced at I/O 2026 was not a model.

It was the disappearance of friction.

At first I dismissed Google AI Studio as another polished keynote demo. Then I realized Google wasn’t showing a coding assistant. It was showing an attempt to compress the entire app lifecycle into one surface.

That distinction matters.

For years, AI-assisted development mostly meant faster scaffolding. Generate some boilerplate. Autocomplete a function. Maybe prototype a UI. But the moment you needed authentication, deployment, testing, data integration, or collaboration, you fell back into the usual maze of setup overhead and infrastructure churn.

This year felt different.

Google AI Studio now sits at the center of a workflow where an idea can move from prompt → prototype → backend → Android test track with surprisingly little context switching. The browser is no longer just where developers read documentation and manage tickets. It is starting to look like the place where software begins.

And honestly, that may end up being the biggest story from Google I/O 2026.

Most dev tools optimize stages. AI Studio is optimizing handoffs.

That was the real insight I kept coming back to while watching the announcements.

Most developer platforms improve one slice of the workflow:

  • better code editing,
  • better deployment,
  • better testing,
  • better backend tooling.

AI Studio feels different because the focus is not just generation. It is continuity.

Google showed a workflow where developers can:

  • generate native Android apps with Kotlin and Jetpack Compose,
  • preview them directly in the browser,
  • connect Workspace data like Sheets and Drive,
  • test apps through browser emulators or ADB,
  • export projects into Antigravity with context preserved,
  • and move directly into Play Internal Testing.

Individually, none of those features are revolutionary.

Together, they are.

Because the painful part of software development has never been creating the first prototype. The painful part is what happens after the prototype:

  • authentication,
  • deployment,
  • collaboration,
  • environment setup,
  • infrastructure wiring,
  • handoffs between tools,
  • and maintaining momentum once the original creative spark fades.

Google’s new stack appears designed around reducing those transitions.

That is a much bigger ambition than “AI coding assistance.”

I tried a small workflow, and one thing surprised me

During one of the keynote replays, I tested the flow by sketching a tiny Android app concept that turned a messy Google Sheet into a lightweight issue tracker.

Nothing ambitious.

Just:

  • issue cards,
  • owner names,
  • due dates,
  • and simple status labels.

What surprised me was not the generated UI.

It was how naturally context carried between steps.

The system understood the structure of the Sheet surprisingly well. Moving from prompt to preview did not feel like starting over repeatedly. Small interface edits happened inside the same flow instead of forcing a tool switch every few minutes.

The strange part was how quickly I stopped thinking about the tooling. After a while, the workflow stopped feeling like “AI-assisted development” and started feeling like a normal creative process with less drag.

That feeling stuck with me more than any individual feature announcement.

Because the real innovation here may not be intelligence alone.

It may be momentum.

The hidden story is convergence

I think many people focused on the flashy AI demos and missed the more important architectural shift happening underneath them.

Google AI Studio, Firebase, and Antigravity no longer feel like isolated products.

They feel like layers of the same pipeline.

AI Studio is becoming the idea-to-prototype layer.

Firebase is increasingly becoming the agent-aware backend layer.

Antigravity looks positioned as the deeper engineering and orchestration layer where larger systems evolve after the prototype stage.

That matters because older no-code and low-code platforms usually collapsed at the handoff point. The prototype was easy, but scaling or customizing it often required a painful rewrite.

Google seems to understand that the handoff itself is the product.

That is why preserving project context, conversation history, and configuration between environments matters so much. The workflow feels less like generating throwaway demos and more like continuing software development across different levels of complexity.

That is a subtle but important shift.

This changes who gets to start

One consequence of cheaper software creation is that more people can participate earlier.

A solo founder can validate an idea faster.

A designer can build a functional prototype before involving engineering.

A product manager can test workflows without waiting on infrastructure setup.

And developers can spend less time wiring repetitive systems before reaching meaningful experimentation.

That does not eliminate engineering complexity.

But it changes where effort gets spent.

If the first draft of software becomes dramatically cheaper, then competitive advantage shifts toward:

  • product judgment,
  • architecture,
  • reliability,
  • systems thinking,
  • and understanding real user problems.

In five years, manually wiring authentication flows, deployment pipelines, and environment setup for early-stage applications may feel as outdated as provisioning physical servers by hand.

That sounds dramatic today.

I’m not sure it will sound dramatic for long.

But there are real tradeoffs

I’m excited about this direction, but I also think developers should stay skeptical in healthy ways.

The first concern is ecosystem gravity.

The smoother the workflow becomes inside a single platform, the easier it is for that platform to quietly define your architecture choices. Fast beginnings can eventually create painful dependencies.

The second concern is over-trusting generated systems.

Production software is not just working code. It is:

  • observability,
  • edge-case handling,
  • debugging,
  • maintainability,
  • security review,
  • and long-term operational ownership.

AI can reduce setup friction. It cannot eliminate responsibility.

And there is a third concern that feels even more important.

Developers still need to understand what the system is doing underneath abstraction layers.

If every workflow becomes:

prompt → preview → deploy

then there is a real risk that engineering understanding becomes increasingly shallow.

The best use of these tools is not avoiding thinking.

It is spending more energy on the problems that actually matter.

The bigger shift

What struck me most was not the AI itself.

It was the fatigue Google appears to be targeting.

Every developer knows the feeling of losing momentum somewhere between the prototype and the deployment checklist. Creative energy dies in setup screens, permissions, configuration files, environment mismatches, and endless integration work.

AI Studio feels like an attempt to preserve that momentum longer.

And honestly, that may be why this feels more significant than another model release.

The tooling is starting to disappear.

The next few years

My biggest takeaway from Google I/O 2026 is that the future IDE may not look like an IDE at all.

It may look like a conversational workspace capable of:

  • generating software,
  • previewing interfaces,
  • configuring infrastructure,
  • testing deployments,
  • orchestrating agents,
  • and handing projects across multiple levels of abstraction without losing context.

In that world, the most valuable developers will not simply be the people who can write everything manually from scratch.

They will be the people who can direct systems well enough to build reliable, thoughtful, useful products quickly.

That is a very different skill.

And I think Google understands that shift earlier than most people realize.

I’m still not sure whether AI Studio is hiding complexity or genuinely removing it, and that may be the most interesting question Google I/O 2026 leaves us with.
