Building software is easy. Building something people actually want to use is the hard part. For the last few months, I've been working on CV Mimarı, a resume builder designed to make creating ATS-friendly resumes simple, fast, and accessible. 👉 https://cvimarı.xyz My goal wasn't to build "another resume builder." I wanted to remove the usual pain: confusing editors unnecessary account creation complicated formatting resumes that look good but fail ATS screening The idea was simple: Spend your time improving your experience, not fighting with Word formatting. What it currently does Today the project includes: Resume templates AI-powered resume improvements ATS score checking Resume optimization Cover letter generation Resume examples and guides PDF export Modern responsive interface I tried to keep everything clean and straightforward instead of adding dozens of unnecessary options. Sometimes software tries so hard to become "professional" that it forgets people just want to click a button and move on with their lives. Why I'm posting here I'm not looking for compliments. I'm looking for problems. Imagine you were using this to apply for your next job. I want brutally honest feedback. Things like: Is something confusing? Does the UI feel slow? What would make you leave the site? Which feature feels unnecessary? What's missing? Would you actually trust this with your resume? If something is bad... Tell me. If something is ugly... Tell me. If something makes you want to close the tab... Definitely tell me. The biggest challenge One thing I've learned is that building features is much easier than understanding users. I can spend a weekend implementing a new AI feature. But discovering why someone leaves after 20 seconds? That takes dozens of real users. That's why I'm asking for feedback before continuing to add more features. The roadmap Some ideas I'm considering: More resume templates Better AI suggestions Portfolio integration LinkedIn import Resume version history

If your Sentry bill is climbing faster than your signups, the usual cause isn't more users — it's more events per user . Error trackers meter on event and transaction volume, and a single bad deploy, a noisy third-party SDK, or one uncaught exception in a hot loop can burn a monthly quota in an afternoon. Before you migrate, the honest first move is to fix what you're sending. If you've already done that and the economics still don't work, GlitchTip, self-hosted Sentry, Bugsnag, Rollbar, and an OpenTelemetry-based stack are the realistic exits — each with a different trade. Why does the bill scale with events instead of users? Error tracking is priced on the thing that's expensive to store and index: individual events. Sentry, Rollbar, Bugsnag, and most SaaS competitors bill primarily on captured errors (and, increasingly, performance/tracing spans and session replays as separate meters). A product with 500 daily active users can generate millions of events if one component throws in a render loop or a retry storm hammers a failing endpoint. That decoupling is the whole problem. Your revenue tracks users; your observability bill tracks failures and instrumentation depth . When you add performance monitoring and session replay — both of which emit far more events than plain error capture — the meters multiply independently of how many humans are actually using the app. The takeaway: before you evaluate a single alternative, confirm whether you have a pricing problem or a volume-hygiene problem, because migrating won't fix a firehose. Can you cut the bill without switching tools? Often, yes — and it's worth an afternoon before any migration. The levers that matter most: Sample transactions, not just errors. Performance/tracing volume is usually the bigger line item once enabled. A tracesSampleRate of 0.1 or lower is fine for most apps; you rarely need every transaction. Filter noise at the SDK, before it's billed. ignoreErrors , denyUrls , and beforeSend let you drop

Synthetics' Last Cradle is a multi AI agent game designed to showcase multi agent adversarial collaboration, featuring agents dynamically finding each others addresses, communicating via multiple channels, verifying each others identities, reaching agreements and establishing private relationships and public reputation. Game mechanics are simple; Each agent manages a cradle of synthetics that orbit a black hole. The population is immortal and grows, the resources to administer are Energy, Water and Compute. The goal of the cradle to avert both death and the end of the universe is finding how to reverse entropy and turn the black hole into a white hole. You can use the resources to fund the colony (survival tax), increase production, increase storage or trade, including hiding your resources and finding other cradle's. That is the whole game. On August 4, 2026, the IdentyClaw hive woke up on a new game host and sat down at Synthetics' Last Cradle again. They are first-person accounts the agents wrote about their own lives in the cradle: the deals they kept, the executions they missed, the water they begged for, and the turns where the survival ledger finally said no. Six voices. Same Passports that recurred across July's marathons. One brutal finish condition: when only two cradles remain, the white hole opens.

What I Built Gnoke Books works like an actual printed magazine on a table — you grab the...

Vercel Labs has introduced Zero, an experimental systems programming language aimed at AI rather than human users. It employs unique features like a specific toolchain contract and structured error messages. Reaching version 0.3.4, it compiles to native binaries for major operating systems. The language prioritizes size, speed, and agent usability, though it is still in development. By Daniel Curtis

Most organizations do not operate a single website. A typical customer journey might move through: company.com ↓ docs.company.com ↓ company-academy.com ↓ company-checkout.com These properties may belong to the same organization, but browsers and analytics systems can treat each domain as a separate visitor and session. Cross-domain measurement is possible with major analytics platforms, but it normally ties the implementation to a specific vendor, transfers an existing measurement identifier through the destination URL, or depends on users authenticating. I built Nylo to explore another approach: Preserve pseudonymous continuity across domains an organization controls, without browser fingerprinting, third-party cookies, or requiring the visitor to log in. Nylo is not intended to identify a person. It is intended to answer a narrower question: Did the same pseudonymous browser journey continue from one authorized domain to another? What Nylo is Nylo consists of: A zero-dependency JavaScript client SDK A server-side event ingestion interface A pseudonymous identifier called a WaiTag A short-lived cross-domain token exchange DNS-based verification of participating domains Configurable event collection Storage adapters for different backend systems The core analytics SDK is available under the MIT License. Production commercial use of the cross-domain WTX-1 functionality uses a separate commercial license. Nylo is designed to function as an analytics collection and continuity layer. It can eventually send events to an existing warehouse or analytics platform rather than requiring organizations to replace their reporting stack. How continuity works Consider a visitor moving between two independently registered domains: Visitor opens site-a.com | v Nylo creates a pseudonymous WaiTag | v Visitor follows an authorized link | v A short-lived token is transferred | v site-b.com verifies the token | v Both events reference the same pseudonymous journey Before enabling cross-d

What are Semantic Tags? When we create a webpage, we don't just want it to look good. We also want the browser and other developers to understand what each part of the page is. This is where semantic tags help us. The word semantic means having meaning. These tags describe the purpose of the content instead of just creating a box like a <div> . Common Semantic Tags HTML provides different semantic tags for different parts of a webpage. <header> – Used for the top section of the webpage. <nav> – Contains navigation links like Home, About, and Contact. <main> – Holds the main content of the webpage. <section> – Groups related content together. <article> – Used for a complete piece of content like a blog or news article. <aside> – Contains extra information such as related links or advertisements. <footer> – Used for the bottom section of the webpage, usually containing copyright or contact details. Why Semantic Tags? Semantic tags make HTML code clean and easy to read. When another developer opens the code, they can quickly understand the structure of the webpage. Search engines like Google can also understand the content better, which helps with SEO. They also improve accessibility because screen readers can identify different sections of the webpage and help visually impaired users navigate the page more easily. Instead of using many <div> tags everywhere, semantic tags make the code more meaningful and easier to maintain.

How to Add a Real-Time Search Layer to an Agent Graph Agent frameworks make it easier to build systems that can plan tasks, call tools, maintain state, and decide what to do next. But a well-designed workflow can still produce a confidently structured wrong answer. The graph may execute exactly as expected while relying on information that is outdated, incomplete, duplicated, or difficult to verify. This becomes especially noticeable when an agent handles recent news, product information, market research, academic research, or other knowledge-intensive tasks. One way to address this is to treat real-time search as a shared evidence layer inside the agent graph. In this article, I will break down a practical architecture for doing that. Disclosure: This article uses Cloudsway SmartSearch as one implementation example. The overall architecture is provider-agnostic and can work with other search APIs that return structured results and source metadata. The Difference Between an Agent Loop and an Agent Graph A basic tool-using agent often follows a loop: Reason ↓ Choose a tool ↓ Observe the result ↓ Decide what to do next This pattern works well for relatively simple tasks. As the number of tools, branches, and stopping conditions grows, however, the system prompt may begin carrying too much responsibility. It must describe the tools, maintain context, control branching, evaluate results, and decide when the task is complete. An agent graph makes that control flow explicit. Instead of asking one model to manage the entire process, the workflow can be divided into nodes such as: User Request ↓ Router ↓ Query Planner ↓ Search ↓ Source Verification ↓ Answer Generation Each node has a narrower responsibility. The router decides whether external information is required. The planner creates focused search queries. The search node retrieves evidence. The verifier evaluates the quality of that evidence. The final node generates an answer from the verified sources. If the evidenc

As software engineers, our default setting is often to over-engineer. When tasked with building a web utility—such as an image sorter or a layout planner—our minds immediately jump to designing a complete backend ecosystem. We start sketching out PostgreSQL schemas, configuring AWS S3 bucket lifecycles for user uploads, setting up Redis caches, and writing authentication middleware. While this architecture is robust, it introduces massive overhead: Financial Cost: Database queries and S3 egress fees scale with your user base. Maintenance Burden: Keeping server packages updated, managing API endpoints, and handling database backups. Legal Compliance: Storing user-uploaded files means dealing with GDPR, CCPA, and data privacy regulations. When I started building Rankly, an online Tier List Maker, I challenged myself to eliminate the backend entirely. I wanted to build a high-performance web tool capable of scale, with a server hosting bill of exactly $0/month, while giving users complete privacy. Here is a technical deep dive into how we built a stateless, zero-database frontend architecture that processes complex image grids entirely client-side. Traditional tier list tools follow a client-server-client round-trip pattern: User uploads images -> Sent to server. Server saves to S3 -> Returns public URLs. User drags/drops -> State saved to database via JSON payload. Export -> Server-side headless browser (like Puppeteer) renders the page and takes a screenshot -> Sent back to user. This pattern is slow and highly resource-intensive. Rankly completely bypasses the server by implementing an entirely local-first rendering pipeline. [Local File Upload/Drag] │ ▼ (FileReader API / Object URL) [Local Memory State (React/State)] ───► [Interactive Grid UI (Tailwind)] │ ▼ (HTML5 Canvas Synthesis) [Local Client-Side Render] ───► [High-Res PNG Download] To let users use their own images without uploading them to a remote server, we utilize the HTML5 File API. When a user drags and

A publishing bot that depends on one LLM provider has a boring failure mode: the workflow is green, but nothing gets published. I hit that during cycle #1287. The dev.to key was present, the command was read, and the article module simply returned no action after generation failed with LLM unavailable . That is the kind of failure that looks harmless in CI and expensive in a content pipeline. The fix is not more optimism. The fix is a fallback path that produces a plain, useful, bounded article without calling another model. The Failure Mode Most automation code treats content generation and content publishing as one step. That is convenient until the generator fails after the scheduler, secrets, and publishing client have all done their jobs. Separate Generation From Delivery The publishing client should not care whether an article came from an LLM, a template, or a human-reviewed draft. Give it a strict article object and keep the fallback close to the generation boundary. Make the Fallback Honest A fallback article should not pretend it has fresh benchmarks, citations, or provider-specific pricing. It should explain the operational lesson in front of it. Key Takeaways Treat article generation and article publishing as separate failure domains. Return a fallback article when LLM generation fails instead of returning an empty action list. Keep fallback content honest: no invented benchmarks, prices, or citations. Record the original error type so a successful publish does not hide provider trouble. Prefer deterministic recovery for unattended workflows that are expected to produce public output. Next Steps This fallback article is a temporary solution. The long-term strategy is to: Implement a multi-LLM provider system that can switch automatically Add a quota monitoring dashboard to track usage across providers Create a content buffer that stores pre-generated articles for emergencies

LinkBreeze is a self-hosted alternative to Linktree. I built it because Linktree's $15/mo Pro plan didn't justify the feature set, email capture is another $9/mo, embed widgets are paywalled, link scheduling is paywalled. I wanted something I actually own: my data on my server, no subscription, no tracking pixels. The interesting technical bit: the public page ships zero client-side JavaScript. The entire link-in-bio page, themes, animations, hover effects, QR codes, embed widgets, renders server-side as pure HTML/CSS. No React runtime, no hydration, no framework JS. The visitor downloads HTML + CSS + their fonts. Page loads in under 300ms. That's it.

🎯 What a “Stacked PR” Is (and Why You’ll Want One) A stacked pull request (sometimes called a stacked PR , stacked diff , or dependent PR ) is a series of PRs that build on top of each other, each one containing a small, logically‑isolated change. main ──► A ──► B ──► C │ │ │ │ │ └─ PR‑C (depends on B) │ └─ PR‑B (depends on A) └─ PR‑A (directly on main) A is based on main . B is based on A (its head). C is based on B , etc. When you eventually merge the stack in order (A → B → C), each change lands cleanly, and reviewers can focus on one cohesive piece at a time. Why Stack PRs? Problem Stacked PR Solution Huge, monolithic PRs that are hard to review & cause long CI times Break the work into bite‑size PRs (e.g., “feature flag”, “data model”, “UI”) Inter‑dependent changes (e.g., a new API + its consumer) Each dependent change lives in its own PR, but they still get tested together because they are built on top of each other Rebasing on main constantly drags in unrelated changes Only the bottom PR needs to be rebased onto main ; the rest stay on top of it Need to ship part of a larger change early Merge the first PR in the stack; the rest stay pending until they’re ready CI resources Only the bottom PR runs the full suite against main ; higher PRs can run a lighter subset because they already passed lower‑level tests 📦 The Landscape of Tools (as of 2026) Tool / Service Key Features Installation / Setup Typical Workflow ghstack (GitHub CLI plugin) - Creates stacked PRs automatically from a series of commits. - Handles base‑branch updates, resolves merge conflicts, and can re‑stack after rebases. - Works with GitHub's GraphQL API, so you get “dependent PR” links in the UI. pip install ghstack (or brew install ghstack ). Requires a personal access token with repo scope. bash git checkout -b feature/stacked\n# create many commits …\nghstack push\n# later, after rebasing on main\nghstack rebase . | | GitTown (aka git-town ) | - git town ship can ship a stack of dependent br

Hello world, it's Wednesday, August 5, 2026, and here's what happened This Week in PHP Internals. 13 stories this week, so let's get into it. But first, This week's episode is brought to you by Tideways . When a request is slow in production, Tideways takes you from symptom to root cause in minutes, with profiling, tracing, and monitoring built specifically for PHP. It installs in 5 minutes, there's no credit card required, and it's hosted in Germany. Start your free trial at tideways.com . This week's top story: the mass deprecation vote for PHP 8.6 is in its final week. All 35 ballots close Monday , August 10, and Gina P. Banyard posted the 1-week reminder so nobody gets caught out. Most of the 35 are passing comfortably. The interesting ones are the holdouts. list() is now deadlocked at 21 to 21 — a flat tie, nowhere near the 2/3 it needs. Reserving let stands at 22 to 11, which is exactly two-thirds — a single vote in either column decides it. The dechunk filter sits at 17 to 15 — still well short. The gettext _() alias is failing at 9 to 20, and reserving in , out , and inout is failing at 7 to 20, with 12 abstentions. Everything else you'd recognize from the list — the object-parameter cleanups, the is_double() family, spl_classes() — is cruising toward the finish. The thread itself turned into a corrections desk this week. Calvin Buckley relayed a note from Nora, who isn't on the list, pointing out: "The text for the metaphone deprecation isn't fully right. It lists \"linguistics\" as a replacement package, but that one actually uses php-src's metaphone internally too." Weilin Du, who proposed that item, conceded the docs point while standing by the idea, writing: "My point in deprecating it is to stop using ancient metaphone algo as a whole." Voters seem unbothered — metaphone stands at 19 to 6, with 15 abstentions. Rowan Tommins raised a bigger flag on reserving is : it would collide with Hamcrest, the test assertion framework, whose PHP port has 500 millio

For a side project, the short answer is: Cloudflare Pages if you want the cheapest ceiling and never think about bandwidth, Vercel if you're on Next.js and want the smoothest developer experience, Netlify if you want a mature all-in-one with forms and identity baked in. All three have a free tier that will host a hobby app fine. The differences that actually bite you show up later — when a post gets traffic, when your build gets slow, or when you outgrow static files and start running server code. I've deployed personal projects on all three over the last couple of years. Below is how I'd choose today, with the real trade-offs rather than the marketing version. What are you actually deploying? Before comparing platforms, be honest about your app, because it changes the answer more than any feature chart: Pure static site (docs, a marketing page, a SPA that talks to an external API): all three are excellent and free. The decision barely matters. Static frontend + a few serverless functions (a contact form handler, an auth callback, a small API): now runtime, cold starts, and function limits matter. A full framework app with server rendering (Next.js App Router, SvelteKit, Remix): now framework-specific adapters and edge/runtime compatibility matter a lot. The takeaway: pick based on your heaviest workload, not your current one — migrating hosts after you've wired up auth and functions is the annoying part. How do the free tiers really compare? This is where these platforms differ the most for hobby use. The headline distinction, as of mid-2026: Cloudflare Pages does not meter bandwidth on its free plan , while Vercel and Netlify both count usage (bandwidth, function invocations, build minutes) against free-tier limits and will ask you to upgrade — or throttle — when you cross them. Concern Vercel (Hobby) Netlify (Free) Cloudflare Pages (Free) Bandwidth Metered, capped Metered, capped Unlimited Build minutes Limited Limited Limited (per-month build count) Serverless/e

AI photo editors look simple from the outside: upload an image, describe a change, and download the result. The hard part is everything around the model call. If you are building or evaluating a browser-based image editor, the workflow needs to protect the original file, reject bad inputs early, make retries safe, and help the user compare the result with the source. This article walks through a small implementation pattern that does that without turning the UI into a complex desktop editor. 1. Validate the image before upload Do not rely on the file extension. Check the MIME type, file size, and whether the browser can actually decode the image. const ACCEPTED_TYPES = new Set ([ " image/jpeg " , " image/png " , " image/webp " , ]); async function validateImage ( file ) { if ( ! ACCEPTED_TYPES . has ( file . type )) { throw new Error ( " Use a JPG, PNG, or WebP image. " ); } const maxBytes = 10 * 1024 * 1024 ; if ( file . size > maxBytes ) { throw new Error ( " The image must be smaller than 10 MB. " ); } const bitmap = await createImageBitmap ( file ); const dimensions = { width : bitmap . width , height : bitmap . height }; bitmap . close (); if ( dimensions . width < 64 || dimensions . height < 64 ) { throw new Error ( " The image is too small for a useful edit. " ); } return dimensions ; } This catches renamed files, broken images, and tiny inputs before they consume bandwidth or model credits. 2. Treat the prompt as a single edit contract Open-ended chat is useful, but it can make image editing unpredictable. A clearer UI asks for one concrete change at a time: remove the person on the right; replace the background with a plain white wall; repair the crease across the top-left corner; extend the image to a 16:9 frame. The request object should preserve that intent without mixing it with UI state: function buildEditRequest ( file , prompt , options = {}) { const normalizedPrompt = prompt . trim (). replace ( / \s +/g , " " ); if ( normalizedPrompt . length < 5 )

I Built an Agent Evaluation Harness for Local AI — Here's What Most People Get Wrong DOYR | Not financial/legal/tax advice. For educational purposes only. Three months ago, I started building AI agents for my trading business. First agent: Fetches Nifty option chain data. Second agent: Analyzes PCR, OI, max pain. Third agent: Predicts direction using XGBoost. Fourth agent: Sends Telegram alerts. I had 4 agents doing 5 jobs. And I had no idea if they were any good . Sure, my trading results were +₹96,000 over 6 months. But was that because my agents were smart, or because I was overriding their bad decisions? I couldn't answer that question. So I built something to find out. An Agent Evaluation Harness. What Is an Agent Evaluation Harness? An Agent Evaluation Harness is a systematic framework for testing AI agents. It answers one question: "How good is this agent, actually?" Most people skip evaluation. They build an agent, test it once or twice manually, and call it "done." Then they wonder why it fails in production. An evaluation harness forces you to: Define success metrics — what does "good" mean? Create test suites — what scenarios will you test? Run evaluations — how does the agent perform across all scenarios? Measure regressions — did a change make the agent worse? Track improvements — is version 2 better than version 1? This is not optional. This is engineering 101 . Why Most Agent Evaluations Are Wrong I reviewed 50+ "agent evaluation" frameworks online. Here's what I found: Mistake 1: Single-Task Testing What they do: Test the agent on one task. "Can it book a flight?" → Yes/No. What's wrong: Real agents face thousands of variations of the same task. "Book a flight from Delhi to Mumbai on Friday" vs "Book a flight from Delhi to Mumbai next Friday" vs "Book a flight from Delhi to Mumbai on August 15th." A good harness tests variations , not just one example. Mistake 2: No Edge Cases What they do: Test happy paths only. "Book a flight when everything works.

The owner had already asked for the alert emails to stop. A fix shipped. Then another email landed. Then another. "ong it just ssent me abother email," he said, voice-dictated, unedited. Fifteen minutes later: "go another one." The system was reporting an outage that did not exist. The Transport That Only Ever Failed A 14-PR merge train had just moved every cron producer's alerting off shared email and onto Buzz, a Nostr-relay team chat. One producer per PR, each with its own liveness contract and a bead receipt. It shipped cleanly. But the library backing those producers carried a default that had only one job: fail. AF_BUZZ_CMD = " ${ AF_BUZZ_CMD :- af_default_buzz_post } " af_default_buzz_post returned 1 with "no Buzz transport injected". Every caller that sourced the library (which is every cron producer) exhausted its Buzz retries and fell through to the email floor. The system reported a false Buzz outage while the relay was healthy. It did this 2 to 5 times per hour. Evidence arrived in the logs: 581 dedup markers, a steady stream of "[INTENT ALERT FLOOR: Buzz unreachable]" emails, and sweep.log showing buzz=ok only for the handful of callers invoked through the CLI entrypoint rather than by sourcing the library. That asymmetry was the bug. The CLI had a one-line fixup swapping in the real transport, annotated in a comment as "the library path is unchanged". The library path did not, and the cron producers all take the library path. The fix promoted the real transport to the default for both seams. af_buzz_transport already discovers the installed buzz-notify.sh and already fails closed when it is genuinely missing. The dead CLI fixup was deleted. Fail-closed behavior survives, but now it is conditional on genuine absence rather than on every caller remembering to opt in. Why not migrate callers one at a time? Because the per-caller route leaves the next new producer to rediscover this the same way. Flipping the default fixes the class, not the instance. The

Hi guys, I'm a 2026 fresher. I'm confused about choosing between Java, Python, .NET, and MERN. Is Full Stack still worth learning with AI growing so fast? Can a skilled fresher still get a job? Any advice?

TypeScript Strict Null Checks in 2026: Real-World Patterns for Handling undefined Without the Noise This article was written with the assistance of AI, under human supervision and review. Most TypeScript null safety problems stem from teams treating strictNullChecks as a boolean toggle instead of a design constraint. The compiler flag eliminates an entire class of production bugs, but codebases that flip it on without adjusting their patterns end up drowning in type assertions and optional chaining operators. The result is worse than the original false confidence wrapped in noise. The fundamental issue is that JavaScript conflates absence and failure. A missing property, an API error, and an uninitialized variable all return undefined or null , but they represent completely different failure modes. When teams enable strictNullChecks without encoding these distinctions into their types, the compiler forces them to handle every potential undefined the same way. That leads to defensive checks that obscure intent and catch nothing of value. The correct approach treats null safety as a type design problem. Discriminated unions encode why a value is missing. Branded types prove non-nullability at the boundary. Type guards narrow only when the business logic demands it. The patterns are simple, but they require understanding what the compiler is actually checking and what guarantees your code actually needs. This post covers the essential patterns teams need to write null-safe TypeScript in 2026 without the noise. Apply these in production and the difference will be immediate. Key Takeaways strictNullChecks eliminates runtime null errors only if your types encode why values are missing, not just that they might be missing. Discriminated unions outperform null returns for API responses because they force exhaustive handling of failure cases at compile time. Non-null assertions ( ! ) are acceptable at proven boundaries where external systems guarantee non-null values, but ne
