Breakdowns, guides and fresh news on building apps with words — from the team behind the KODiQ learning app.
The download attribute not working and your PDF opens in a tab? Three causes — a different domain, fetching without saving, and in-app browsers — and how to fix each.
The Shadow DOM in plain words: why page styles don't apply inside a widget while fonts and colors leak in, and why querySelector can't find a button you can see.
Optimistic locking in plain words: how two editors silently overwrite each other, and how a version column in your database catches the conflict before it lands.
A state machine in plain words: why three flags — isLoading, isError and data — give you eight states instead of four, and how a single status fixes it.
useState vs useRef in React: which one triggers a re-render, when you see the new value, and where to keep a timer id. A simple rule for which to pick.
How to make responsive font size in CSS with clamp(): a two-point formula, ready-made values, and why font-size in pure vw refuses to grow when users zoom in.
fetch returns stale data even though the database has new data? We cover 3 caching causes: Next.js built the page at build time, the browser cache, and a CDN.
What backpressure is, in plain words: the receiver's “slow down” signal to a data source. Why your script eats memory without it, and how to fix it in Node.
What a percentile is, in plain words: p50, p95 and p99 in speed metrics. Why average response time fools you, and how to calculate a percentile yourself.
What a cache stampede is: a hot key expires and hundreds of requests hit the database at once. Why it happens and three ways to prevent it in your app.
PUT vs PATCH in a REST API: full replacement vs partial update, idempotency, null in the body, and the fetch method: 'patch' trap. Which one to pick and when.
How to calculate days between two dates in JavaScript without an off-by-one: time of day, time zones, input type=date and Temporal. A ready function plus tests.

Changed one item and they all changed? Three reasons every array item changes at once: fill, an object reused in a loop, a shared default — and fixes.

What integer overflow is, in plain words: a number hits its ceiling and wraps into the negatives. Where 2,147,483,647 breaks real apps.

What a sparse array is, in plain words: holes instead of elements. Why Array(3).map does nothing, and why the array's length lies to you.

What a semaphore is, in plain words: a counter that lets at most N tasks use a resource at once. How to limit parallel requests with it and avoid 429s.

input vs change in JavaScript: when each event fires, which one to use for search, sliders and checkboxes — and why React's onChange works differently.

How to capitalize the first letter of a string in JavaScript and CSS: step by step, with empty strings, leading quotes, Turkish i and names like McDonald.

Video generators invent a road. A new open skill takes yours: the route, the buildings from their real footprints on the map, the real hills and horizon. It hands you one .html you fly along with the scroll wheel. The free tier swaps the art for code-drawn stand-ins.

AI has long drawn pretty diagrams of machines. What's new is an open skill where the agent builds a working model of a real one: you drag the throttle and 340 kN comes out of an equation, not a table. One .html file, buildable over a weekend.

Letting an agent drive an iPhone used to take a Mac, Xcode and a developer account. A new open project gets there with a tiny ESP32 board that pretends to be a mouse, while the model watches the screen over AirPlay. A weekend build.

Why JavaScript gives you NaN instead of a number: an empty field, text instead of a number, zero divided by zero. How to find the source of NaN and fix it fast.

What a string is, in plain words: text in quotes. Why "2" + "2" gives "22", an emoji counts as two characters, and everything from a form arrives as a string.

What return does in a function, in plain words: the answer a function hands back. Why console.log shows a number but your variable holds undefined.

What a boolean is, in plain words: true or false. Why "false" in quotes counts as true, an empty array does too, and zero counts as false.

let vs const in JavaScript: what the difference is and which to pick. A criteria breakdown, a one-second rule, and why const doesn't mean "can't change."

How to safely rename a variable or function across a whole project: why Find and Replace breaks code, and how to do it in 6 steps with F2 and a final check.

AI video usually means “generate something new”. Meanwhile your own clips just sit in the camera roll. A free engine just shipped that lets an agent watch your footage, listen to the track and cut to it — and hand back a project you can fix with one sentence.

The array is empty, the screen shows nothing, the console is silent. Three real causes of an empty array — data not there yet, a filter that cut everything, a list nested deeper — and how to check each.

What is an array in plain words: a list that keeps its order. Why counting starts at zero, where the most common beginner bug comes from, and why an empty array matters.

What is a loop in programming, in plain words: repeat one action for every item in a list. Why you almost never know the number of repeats in advance.

What is a callback in plain words: a function you hand over instead of calling. Why it works that way, where you've already written one, and which parentheses break everything.

How to find the right file in a big project fast: don't scroll the folder tree, search for the label you can see. Five steps from a button in the app to a line of code.

Array vs object: how they differ and which to pick for your data. A one-sentence rule, a breakdown by criteria, and why searching an array is a thousand times slower.

The agent says «done» and nothing changed in your app. Three real causes: wrong folder, a twin file with the same name, and editing generated code.

An Agent Skill is a folder with one SKILL.md file. The agent only remembers a one-line description and reads the full instructions when a task matches.

A subagent is a separate agent with a clean memory. It reads forty files and hands you back five lines: all the search noise stays with it, not with you.

A git worktree is a second working folder on the same project history. Two branches open at once, no switching and no stashing half-finished work.

Ask an AI to write the awkward email and you get three options, a preamble and a note on which to pick. Yesterday someone open-sourced weights that just hand over the text. That's a “copy — send” button.

Step by step: create the folder, write SKILL.md, get the agent to pick it up by itself. Plus the fix for the one mistake that keeps skills from firing.

MCP gives an agent access to a live system; a skill gives it the procedure. We compare context cost, when you need a server, and when a folder is enough.

Green locally, red in CI. The three real causes of tests failing in CI — and why, in that argument, CI is usually right and your machine is the liar.

State is everything your app remembers between two clicks. What state is in plain words, and why interfaces break wherever one truth is stored twice.

A regression is an old bug that came back. What a regression is in plain words, why someone else's edit usually brings it, and how to catch it for good.

A dependency is someone else's code running inside your project. What a dependency is in plain words, why there are hundreds, and when to just write it yourself.

Agents almost always suggest rewriting — because rewriting is cheaper for them than understanding. Five criteria for when to refactor and when to start over.

Models rarely write syntactically wrong code — they write plausibly wrong code. Six steps for reviewing AI-generated code that catch it in ten minutes.

You added the MCP server but there are no tools, or it sits on 'Failed to connect'. Here are four causes ordered by frequency — and how to check each in a minute.

AGENTS.md is a plain Markdown file in your project root. AI coding agents read it on their own before they start. Here's what belongs in it — and what stays in the README.

A variable isn't a box holding a value — it's a tag attached to one. That's the bug every beginner hits: you edit the copy of a list and break the original.

A diff isn't a report of what changed — it's a recipe for turning the old version into the new one. Learn to read minuses, pluses and those @@ marks in five minutes.

Connecting an MCP server to your agent takes one terminal command. Step by step: hosted and local servers, how to verify the connection, where the config lives.

Horizontal scrolling on mobile: three real causes and a snippet that names the guilty element instantly. Plus why overflow-x hidden is a bad fix.

What z-index actually is: why a modal with z-index 9999 still slips under the header, what a stacking context is, and how to fix it without bigger numbers.

The CSS box model in plain words: why width 350px renders as 370px, what box-sizing border-box changes, and why four 25% columns don't fit on one line.

No focus outline when you press Tab? Four causes: outline: none in your CSS, a clipping parent, a sticky header and color — how to check and fix each.

Tab order is the queue the Tab key follows through links and fields. Where it comes from, why CSS order breaks it, and which tabindex values are safe.

What ARIA is in plain words: labels for screen readers that change only how an element sounds, not how it behaves. And why bad ARIA hurts more than none.

A mega menu is a large dropdown panel with a site's sections. When it beats a regular dropdown, why a half-second pause matters, and Amazon's triangle trick.

How to store filters, sort order and the active tab in the page address: six steps with URLSearchParams, pushState vs. replaceState, and ready-to-use code.

The form empties itself after an error and people retype it all. Three causes: a blank server re-render, a remounted component, and a Back that never restored.

Autofill doesn't read your name or id — it reads the autocomplete attribute. Here's the word list browsers look for, and why you can't just switch it off.

An input mask types the brackets and dashes for you. Here's why it validates nothing, where pasting breaks it, and what to use instead in your forms.

A required field is the required attribute plus a marker for humans. Why NN/g and GOV.UK give opposite advice — and how to pick the rule for your own form.

A step-by-step walkthrough: how to split a long form into screens, where to keep the answers, how not to lose them on Back, and why you need a review screen.

Dropdown vs radio buttons compared on the criteria a beginner can actually see: taps, visible options, small screens — plus a straight rule for choosing.

On desktop the tooltip appears on hover; on a phone it's missing or stuck. The three real causes — hover, the title attribute, clipping — and the fixes.

Not «send a prompt, wait for an mp4». A session streams video for up to 15 minutes while your commands fly into it live — and the character stays the same. A weekend build with a ready starter prompt.

Why the model refuses your request: a trigger word fired, context was missing, or it wasn't the model at all. Three causes, and what to do about each.

An AI detector doesn't see AI. It measures how predictable your text is — which is why it flagged 61% of essays by non-native writers. Here's how it works.

A false positive is a system accusing someone innocent. Let's do the math on why a filter that's 99% accurate produces half its flags in error.

A confidence score is how sure a model is of its words, not of their truth. Where the number comes from, and why fine-tuning made it lie.

Word blocklist vs AI moderation: compared on cost, evasion, languages and false positives — with a straight answer on what to use in your first app.

How to add content moderation to your app: a free endpoint, 13 categories, three outcomes instead of a ban, and checking the model's output too.

You mutter your thoughts into the phone while walking, and the app hands back not a wall of text but sorted items: tasks, decisions, ideas. And it doesn't trip over your jargon.

Record 30 seconds of your speech, and any text gets read out in your own voice. A year ago you needed a studio. Now it's a weekend build.

A good prompt isn't a polite request — it's a brief. Five steps with a real example: role, context, example, format, and one round of feedback.

Both are VS Code forks with AI inside. The difference isn't the engine — it's how much they decide for you. A practical comparison, with a clear verdict.

Not 50 trendy services — the 7 pillars a beginner actually needs: where to write, what to think with, where to ship. What to grab, when, and the catch.

You describe what you need in plain words, and an agent writes, runs and fixes the code. Here's what the process is — and the first three moves to make.

One setting decides whether the AI answers dull and identical or creative and risky. At zero it's by-the-book; turn it up and it writes poetry, but it may also make things up.

The model never trained on your documents — yet it answers from them. The trick is that it gets handed the right snippets right before answering. That's RAG.

MCP is USB for AI agents. One common port, and an agent can reach your browser, your database and your files — no custom adapter for each.

In a long chat, old messages get pushed out of the model's memory — that's why it loses the thread. Explained with a simple picture.

The model confidently spat out nonsense. Feels like a lie. But it can't lie — it has no idea what truth even is. Let's see how it works and how to catch it.

A chatbot answers, then waits. An agent acts: it opens your files, runs the code, reads the error and fixes it. The difference is what it does, not just what it says.

The same sentence costs a model more in Russian than in English. Tokens are why — let's see what they are and how to pay less.

A prompt feels like a question you ask the AI. It's really a brief for a worker. Flip that, and the answers stop surprising you.

AI turns words into coordinates on a map of meaning. Close meanings land near each other — so it searches by meaning, not by exact words.

The most common one isn't even technical. It's treating the agent like a wizard instead of a junior who needs a clear brief. Let's walk through five in a row.

A short list of ideas, each with the skill you'll practice. From a timer to a Telegram bot. Pick one and start today.

It feels like you need a subscription to start. You don't — everything you need has a free tier, enough to build your first project and show it to people.

"Deploy" sounds scary. It really just means "give your project a link other people can open" — and an agent does it for you in a couple of minutes.

Spoiler: there's no "best." There are three different ways of working — and the right one matches your temperament, not some review's top spot.
