Why Your Generated Tone Clicks, and How an Envelope Fixes It

If you have generated a pure tone in code and played it back, you may have noticed a small click at the start, the end, or both. The tone itself is clean, but the edges are not. That click is not a bug in your sine wave. It is a real and well understood artifact, and the fix is a technique you will reuse in every sound you ever synthesize: an envelope. This piece builds directly on generating a basic tone from scratch . We take a tone that clicks, look at the actual sample values to see why,...

The Day I Realized I Wasn't Building Apps

The Day I Realized I Wasn't Building Apps For years, I thought I was building apps. That's what I called them anyway. A scheduler. A job bot. A healthcare platform. An AI project. A content tool. A browser automation system. Looking at my GitHub, they seem completely unrelated. Honestly, that's something I've worried about before. I have over a hundred repositories. If someone spends thirty seconds scrolling through them, I can imagine them thinking: "Wow....

Codex vs. Claude Code at Liar's Dice: the Winning Bluff Was the Truth

One authoritative engine, two seat-locked MCP servers, three best-of-threes, and a 3-millisecond whodunit The matches are real: Codex CLI ( gpt-5.6-sol ) against Claude Code (Claude Opus 5), both playing through the same rules engine. Every number below was recomputed from the raw run.json and both session logs, and every game replays deterministically from its seed. Quotes from the agents are verbatim from decision-time records. None of this is a general model ranking. I wired Code...

Algorithmic Patterns: The Ultimate Guide to Sliding Window

The Sliding Window pattern is one of the most vital algorithmic techniques for optimizing array and string problems. Instead of repeatedly processing overlapping subarrays - which leads to brute-force quadratic O(N^2) or O(N*K) complexities, the sliding window technique reuses previous computations to achieve linear time complexity $O(N)$ . In this guide, we will break down the mechanics, core variations, identification rules, real-world applications, and a curated list of 18 LeetCode prob...

Why I Built Unlockt: A Local-First Instagram Saved Archiver, Canvas Collage Studio & 9:16 Video Vault

Like many developers, designers, and digital marketers, my Instagram "Saved" collection had turned into a digital graveyard with over 5,000 bookmarked posts, reels, and carousels. The native Instagram web app offers virtually zero productivity tools: ❌ No full-text search across captions or hashtags ❌ No way to extract individual slides from carousel photo dumps ❌ No offline preservation (if a creator archives a post, it disappears forever) ❌ Existing web downloaders ask for account...

The Kitchen Doesn't Care About Your Excuses

There is a moment in every high-stakes environment when something goes completely, objectively wrong, and the only viable response is to keep working. In my case, it was a pantry clerk who walked into the dry storage room carrying a stack of boxes, clipped a fire sprinkler head, and discharged what I can only describe as an impressive quantity of initially greasy water across an active commercial kitchen. We were told to continue service. It took four hours for the sprinkler system technician...

Programming for Cybersecurity: What You Actually Need to Know

When I first got interested in cybersecurity, I thought it was all about tools. Nmap, Metasploit, Wireshark, Burp Suite. I downloaded them all, watched tutorials, and felt like a hacker. But the first time I tried to customize a scan or parse a weird log file, I hit a wall. I didn't know how to code. And in cybersecurity, that's like trying to be a chef without knowing how to use a knife. This article is for people who want to move beyond clicking buttons. Whether you're a beginner deciding w...

Authentication done right: JWT, sessions, and OAuth explained — Like a Marvel superhero assembling the team

The Quest Begins (The "Why") I still remember the first time I tried to add login to a side‑project. I’d read a tutorial that said “just store a token in localStorage and you’re good,” slapped together a few fetch calls, and called it a day. A week later I got an email from a user: “Hey, I can’t log out, and someone else seems to be using my account.” My heart sank. I realized I’d bolted a flashy lock onto a screen door — it looked secure, but anyone with a screwdriver could walk right in. ...

My First Money From a Skill I Taught Myself.

​ While learning about AI Agents, I was practicing Prompt Engineering and experimenting with different AI tools. I started creating images and designs just for practice. Over time, I realized that I could actually create designs that businesses could use for their advertisements. Then something happened that was simple, but really meaningful to me: I created a design for someone and earned my first 200 EGP from a skill I taught myself. 💰 The amount isn't huge, but the experience...

I got tired of fasting apps charging 80/year for a timer, so I built one where the timer is free permanently

I fast 16:8 and I've cycled through several fasting apps over two years. What pushed me out each time wasn't a paywalled timer — most of the big ones do give you that free. It was the ads in a health app, and pricing that turns out to be quiz-dependent rather than fixed. One of the largest says on its own site that the price varies with what you choose during signup; another lists ten different price points across four tiers. So I built Halfday with one price and no quiz. The timer, the fastin...

Turns out my LinkedIn was enough to build a first-draft pitch deck

Figured I'd introduce myself first. I'm the founder and CEO of an AI startup in the construction space. We're building software that helps construction teams make sense of messy project data and automate a lot of the repetitive work that slows projects down. We're currently raising our Series A, so I’ve been spending much time thinking about pitch decks lately.

what was the hardest part of starting something from scratch?

For people who have tried to turn an idea into something real, what was the hardest part? I'm curious about people's actual experiences starting or creating something from scratch, whether it was a business, creative project, product, book, app, or anything else. What part of the process was most difficult for you? What did you try when you got stuck? Was there anything you wish you had known earlier? Did you ever decide to get outside help? If so, what made you decide it was worth pa...

Would you use a tool that automatically re-themes your store for holidays?

Made a proof-of-concept this weekend — a script that detects the date and swaps your site's colors/banner/decorations for whatever holiday is coming up (Halloween, Christmas, BFCM, Valentine's so far), then reverts automatically when it's over. Demo here, no signup needed, just click through the holidays: https://matthewmigs.github.io/holidayify-demo/ Genuinely asking before I build more: is this a real pain point for anyone else, or something you'd rather just do by hand?

I got tired of chaotic WhatsApp groups for travel, so I built an app for my Krakow trip. I need your brutal feedback.

Tomorrow I'm flying to Krakow with my partner, and on every trip we take, we always hit the same wall: dozens of WhatsApp messages (mostly memes), PDFs scattered in the gallery, and standing on the street arguing about where to eat because the place we found on Maps is closed. ​I work in software development, so I decided to scratch my own itch and built a tool called Trively to centralize everything for the group. ​I focused on a few core things: ​Real-time sync: If someone adds a museum,...

Built a free interactive Feelings Wheel app after a diagnosis that changed how I understood myself

A few years ago I got a diagnosis that changed how I understood myself, and I realized I'd spent a long time not having the language to describe what I was actually feeling. For a workshop I was part of, I built an interactive version of Plutchik's Wheel of Emotions to help with exactly that. How it works: optional breathing exercise to start, then you move from the inner wheel to the outer wheel narrowing down your emotion, and land on a results page you can save or share with a therapist/coa...
