Welcome to our weekly digest, where we unpack the latest in account and chain abstraction and the broader infrastructure shaping Ethereum. This week: Ethlabs launches as an independent EF-origin R&D lab backed by Bitmine, Sharplink, and Joe Lubin; the Ethereum Foundation reorganizes into five focused clusters and parts ways with a fifth of its staff; Starknet brings confidential USDC payments to DeFi through its STRK20 framework; and a new industry report charts how crypto-native neobanks went mainstream and why account abstraction matters more because of it. Ethlabs Launches as an Independent R&D Lab The Ethereum Foundation Restructures Into Five Clusters Starknet Brings Private USDC to DeFi Crypto Neobanks Cross From Experiment to Infrastructure Please fasten your belts! Ethlabs Launches as an Independent R&D Lab A coordinated group of Ethereum contributors has launched Ethlabs , an independent nonprofit research and development lab built to ready the network for its next wave of institutional and agentic adoption. The funding effort is led by Bitmine, Sharplink, and Ethereum co-founder Joe Lubin, with support from Anchorage, Octant, and SNZ. Ethlabs is cofounded by five former senior Ethereum Foundation researchers — Ansgar Dietrichs, Barnabé Monnot, Caspar Schwarz-Schilling, Josh Rudolf, and Julian Ma — who between them shaped finality, scaling, data availability, and protocol economics over the past decade. Dietrichs serves as Executive Director. The lab’s early work centers on what institutions need to move onchain at scale: faster settlement, native issuance, cross-chain movement, and more mainnet capacity, alongside research into ETH’s monetary properties. The team frames the moment as Ethereum’s shift from infrastructure buildout to an age of adoption, where the architecture that settles global activity is being decided now rather than in ten years. To preserve neutrality, funding flows through an independent grants administrator that handles screening and
The $765K NFT exploit nobody using block.timestamp thinks about In May 2021, an attacker exploited the Meebits NFT mint, one of Larva Labs' projects, by taking advantage of its predictable randomness mechanism. Meebits used on-chain inputs including block timestamp, nonce, and difficulty to generate the token ID for each newly minted NFT. Different token IDs had different rarities, and rarer IDs were worth significantly more on the secondary market. The attacker figured out the generation formula, simulated the outcome before committing, and repeatedly rerolled mints within the same transaction until hitting a rare NFT. They walked away with a Meebit later sold for roughly 200 ETH, worth approximately $765K at the time. The contract did exactly what it was programmed to do. The problem was the inputs it trusted as "random" were never actually random at all. This is day 7 of the 28-day Chainlink architecture series. Today covers Chainlink VRF: why on-chain randomness is a fundamentally hard problem, how VRF solves it cryptographically, and a detail most explainers skip entirely: why even a fully compromised node operator can't bias a VRF output. Why blockchains can't generate real randomness natively Smart contracts are deterministic. Every node in the network runs the same code on the same inputs and must arrive at the same result, every single time, or consensus breaks. That determinism is what makes blockchains trustworthy. It also makes native randomness structurally impossible. Any value a smart contract can read mid-execution: block.timestamp , blockhash , block.difficulty , block.prevrandao is visible to validators and miners before the block is finalized. That visibility creates a manipulation window block.timestamp : validators can manipulate this within roughly a 15-second window on Ethereum. Small enough that nobody notices, large enough to flip a coin-flip lottery in your favor repeatedly. blockhash : if a validator is about to mine a block where the hash
Originally published on wp-nota.com . You installed an SSL certificate and moved your WordPress site to HTTPS — but the browser still shows "Not Secure" in the address bar, or a padlock with a warning. This is the classic mixed content problem: your pages load over secure HTTPS, but some resources on them — images, scripts, or stylesheets — are still being requested over insecure HTTP. Browsers flag the whole page as not fully secure until every resource is served over HTTPS. Here's how to fix it for good. What "Mixed Content" Actually Means When a single page mixes secure (HTTPS) and insecure (HTTP) resources, that's mixed content. The page itself may be secure, but if it pulls in an image or script over http:// , the browser can't guarantee the whole page is safe — so it drops the padlock or shows a warning. The cause is almost always old http:// URLs still saved in your database or hardcoded in your theme. Step 1: Confirm the Certificate and Site URLs First, make sure the foundation is right. Your host must have a valid SSL certificate installed (most offer free Let's Encrypt certificates). Then, in WordPress, go to Settings → General and confirm both WordPress Address (URL) and Site Address (URL) start with https:// . If they still say http:// , update them, save, and log back in. Step 2: Find What's Loading Over HTTP To see exactly which resources are insecure, open the problem page in your browser, right-click and choose Inspect , and look at the Console tab. Mixed content warnings list each http:// resource by URL — often images in old posts, a hardcoded logo, or an asset from a plugin or theme. This tells you precisely what needs fixing. Step 3: Update Old HTTP URLs in the Database The most common fix is a database search-and-replace that swaps every http://yourdomain.com for https://yourdomain.com . Two safe ways to do it: The easy way — the free Really Simple SSL plugin detects insecure URLs and rewrites them to HTTPS automatically, which resolves most mix
If you've spent any time exploring backend engineering, distributed systems, or system design, you've almost certainly seen one book recommended more than any other: Designing Data-Intensive Applications , or DDIA for short. For years, I've heard experienced engineers describe it as the book that completely changed the way they think about software architecture. When the second edition was released with updated content covering modern distributed systems and cloud-native architectures, I decided it was finally time to see whether it deserved the hype. After reading it from beginning to end, I understand why this book has become a classic. It isn't another programming book that teaches a framework, a database, or a cloud platform. Instead, it teaches something much more valuable: how to think about building systems that continue working when data grows, traffic increases, and failures become inevitable. If you're a backend engineer—or want to become one—this is probably one of the best technical books you can read. This Isn't Really a Database Book The title can be a little misleading. Before opening DDIA, I assumed it would spend hundreds of pages comparing databases or discussing storage engines. Databases are certainly a major part of the discussion, but they're really just one piece of a much larger picture. The book is about designing systems that process enormous amounts of data while remaining reliable, scalable, and maintainable. Those systems happen to rely on databases, but they also involve replication, partitioning, distributed communication, stream processing, fault tolerance, consistency, messaging, and dozens of other architectural concepts that appear in modern software systems. By the end of the first few chapters, it becomes clear that the authors aren't trying to teach products. They're teaching engineering principles that remain useful no matter which technologies you're using. It Explains Why , Not Just How One of my favorite things about DDIA is
Most backend engineers already know how to handle HTTP errors. 400 means the request is bad. 401 means auth failed. 429 means rate limited. 500 means something broke upstream. Retry a few times, add exponential backoff, log the response body, move on. That works fine for many APIs. It works badly for LLM APIs. LLM providers may use normal HTTP status codes, but the operational meaning behind those errors is different enough that treating them like ordinary REST failures can make your app slower, more expensive, and harder to debug. The mistake I kept making Early on, I handled LLM failures the same way I handled every other external API: if ( response . status === 429 || response . status >= 500 ) { retryWithBackoff (); } Simple. Familiar. Dangerous. That logic misses the actual question your app needs to answer: What kind of LLM failure happened, and what should the product do next? Because an LLM API failure is rarely just "one HTTP request failed." It can break: a user-facing chat response a background agent run a document generation job a tool-calling workflow a batch evaluation pipeline a structured JSON generation step And each one needs different handling. Not all 429s mean the same thing For a normal API, 429 Too Many Requests usually means: Slow down and retry later. With LLM APIs, 429 can mean several different things. It might be a temporary rate limit: { "error" : { "message" : "Rate limit reached" , "type" : "rate_limit_error" } } Retrying with backoff may help here. But it might also mean quota exhaustion: { "error" : { "message" : "You exceeded your current quota" , "type" : "insufficient_quota" } } Retrying this does not help. It just adds latency, noisy logs, and a worse user experience. It could also be model-specific pressure. One model may be overloaded while another model from the same provider, or a different provider, would work fine. So your handler should distinguish between: temporary rate limit hard quota exhaustion model-level capacity is
I used to spend ten hours every week doing content research manually. Checking competitor blogs. Scanning Reddit threads. Copying and pasting search results into a spreadsheet. Trying to spot patterns in an ocean of unstructured text. It was exhausting, slow, and completely unnecessary. Once I learned to automate this with Python and a few affordable APIs, I cut that ten-hour grind down to under thirty minutes. Here is the exact system I built, what it costs, and how you can replicate it yourself. The Quick Answer To automate content research with Python, combine a search API like Serper to pull structured Google search data, BeautifulSoup or requests-html to parse page content, and an LLM API like Gemini to synthesize insights into actionable content briefs. Connect these three components in a sequential Python pipeline and you have a fully automated research agent that runs in minutes instead of hours. What I Actually Built I needed a system that could do three things automatically: First, find what real people are asking about any topic across Reddit, Quora, and Google search. Second, identify what my top competitors have written about that topic and where the gaps are. Third, summarize everything into a clean content brief I can use to write or generate an article. I built this using Python with three core components: the Serper API for search data, BeautifulSoup for page parsing, and the Google Gemini API for synthesis. Total monthly cost: about twelve dollars. I document the full working version of this system — including the Flask web interface and WordPress publishing integration — at https://zerofilterdiary.com Step-by-Step Build Guide Step 1: Install the Required Libraries pip install requests beautifulsoup4 python-dotenv google-generativeai Step 2: Set Up Your API Keys Create a .env file in your project root: SERPER_API_KEY=your_serper_key_here GEMINI_API_KEY=your_gemini_key_here Step 3: Search for Real Discussions Using Serper API import requests import

Introducing GlintCode ✨ I've been building GlintCode , a lightweight scripting language for the browser that runs on top of JavaScript. The goal is simple: make building browser apps easier with a clean, beginner-friendly API while still using the power of JavaScript under the hood. Features 🚀 Runs directly in the browser 📝 Uses <script type="glint"> 🌐 Built-in DOM helpers 🎨 Simple UI creation functions 🔁 Built-in loop helpers 📦 Optional module system ⚡ No build tools or compilation required Hello, World <script src= "https://fast4word.github.io/glintcode/glint.js" ></script> <script type= "glint" > page ( " Hello " ) heading ( " Welcome to GlintCode " , 1 ) paragraph ( " Your first Glint app! " ) button ( " Click Me " , () => { print ( " Hello from Glint! " ) }) </script> Why GlintCode? JavaScript is incredibly powerful, but for beginners or small browser projects it can sometimes feel more verbose than necessary. GlintCode provides a set of simple, readable functions that make creating interfaces and interacting with the page easier, while still letting you use JavaScript features whenever you need them. Because GlintCode runs on top of JavaScript, you can gradually learn the underlying language without giving up access to the browser's APIs. What's next? I'm continuing to expand GlintCode with new functions, modules, examples, and documentation. Future plans include additional built-in libraries, a richer module ecosystem, and more developer tools. I'd love to hear your feedback, suggestions, or ideas for features you'd like to see! GitHub: https://github.com/Fast4word/glintcode

I built a browser-based bitwise calculator that performs AND, OR, XOR, NOT, NAND, NOR, XNOR, arithmetic/logical shifts, and rotate operations on 32-bit integers — with a live clickable bit grid. Try it 🔗 Bitwise Calculator — DevNestio Features 13 operations : AND, OR, XOR, NOT A/B, NAND, NOR, XNOR, SHL, SHR, SHRA, ROTL, ROTR Visual 32-bit grid : Click any bit to toggle Operand A on the fly Multi-base input : Auto-detect 0xFF , 0b1010 , 0o17 , or decimal 4 output formats : Hex, decimal, binary (grouped), octal — all with copy buttons No server, no upload — everything runs in-browser The JavaScript integer trap Bitwise ops in JS coerce values to signed 32-bit integers. To get unsigned results you need >>> 0 : case NOT_A : return ( ~ a ) >>> 0 ; // without >>> 0, ~0 shows as -1 case XNOR : return ( ~ ( a ^ b )) >>> 0 ; case ROTL : return (( a << s ) | ( a >>> ( 32 - s ))) >>> 0 ; Rotate without a dedicated instruction JavaScript has no ROL/ROR, so combine two shifts: // Rotate left by s bits (( a << s ) | ( a >>> ( 32 - s ))) >>> 0 Tested with 99 assertions All core logic — parsing, computing, edge cases like XNOR with ~0xFF = 0xFFFFFF00 — covered in a Node.js test file using assert .

Last time I wrote about using glasp, a Go-based, npm-free CLI for Google Apps Script (GAS), in GitHub Actions. Previous post: Lean, Fast, Simple — npm-free GAS Deployment on GitHub Actions with glasp This time, a quick rundown of what landed in v0.3.0 and v0.4.0 . v0.3.0: PKCE support glasp login now supports PKCE (RFC 7636) as an opt-in. glasp login --pkce # or GLASP_USE_PKCE = 1 glasp login Each login generates a code_verifier and sends an S256 code_challenge to Google. It's a defense against authorization code interception, and it coexists fine with the existing client_secret flow. It only applies to the interactive login — --auth / GLASP_AUTH for CI is untouched. Off by default. Worth turning on if you're in a stricter security environment. v0.4.0: Timeouts and retries The focus here is basically "can this run unattended in CI/CD without falling over." Timeouts Script API requests previously had no timeout — a stuck request could hang the job indefinitely. v0.4.0 adds a 180s default. glasp push --timeout 60 # set to 60s glasp push --no-timeout # disable Also configurable via GLASP_TIMEOUT / GLASP_NO_TIMEOUT env vars or timeoutSeconds in .glasp/config.json . Priority: --no-timeout > flag/env > config > default. If the config file is broken, it warns instead of silently falling back. Retries Transient failures (5xx, 429) now get retried automatically. glasp push --max-retries 5 glasp push --no-retries 3 retries by default (up to 4 attempts total) Only applies to idempotent commands: push , pull , clone , list-deployments Commands with side effects ( create-script , run-function , etc.) are never retried Exponential backoff with jitter, respecting Retry-After It's implemented as a single http.RoundTripper wrapper, so the Google SDK itself isn't touched — same pattern as the timeout implementation. retryTransport → oauth2.Transport → http.DefaultTransport Some refactoring, too Internal packages got reorganized ( #107 ), and the hand-rolled retry transport was swappe
I built GameDeck — a gaming platform where you pick a badge, type a name, and play. That's it. No accounts, no launcher downloads, no tracking. Here's how I built it and what I learned. The stack Frontend : Pure browser-based, vanilla JS Deployment : Google Cloud Run i18n : 3 languages (EN, 简体中文, 繁體中文) with instant switching Identity : Emoji badge system — no usernames, no passwords The architecture The entire app is a single-page browser app. No backend for user auth (because there is no auth). Sessions are ephemeral — nothing is stored. Multi-language i18n Adding 3 languages was the #1 feature request within 24 hours of launch. Simple key-value translation maps, no framework needed. The badge identity system Instead of usernames, users pick an emoji badge (🎮 ⚡ 🦊 🐉 🐼 🚀 🐱 🐯 🌟 🍿). This turned out to be the most talked-about feature. It's fun, zero-friction, and surprisingly expressive. Privacy by default No data collected. No cookies. No analytics. Just the game. Privacy isn't a feature — it's the absence of features that invade privacy. What I'd do differently Multi-language from day 1 More game variety before launch Better mobile responsiveness Try it : https://gamedeck-804028808308.us-west2.run.app Source : Built solo, open to questions! Would love feedback from the dev community — especially on the browser game architecture and i18n approach.
Your portfolio is often the first impression a recruiter, client, or fellow developer gets of you. If it loads slowly, ranks nowhere on Google, or is a pain to update, it's working against you instead of for you. Here's how I approached optimizing mine — covering performance, SEO, and everyday usability. 1. Start With a Lightweight Foundation The biggest performance wins come before you write a single line of custom code. Pick a lean stack. Static site generators (Astro, Next.js with static export, Hugo, or even plain HTML/CSS/JS) ship far less JavaScript than a full SPA framework for a mostly-static portfolio. Avoid unnecessary UI libraries. A heavy component library for a five-page site adds kilobytes you don't need. Hand-roll simple components instead. Use system fonts or self-host web fonts. Pulling fonts from a third-party CDN adds an extra DNS lookup and render-blocking request. Self-hosting with font-display: swap avoids layout shift and speeds up first paint. 2. Optimize Images (This Is Usually the Biggest Win) Images are almost always the heaviest assets on a portfolio site. Convert images to WebP or AVIF — typically 30–50% smaller than JPEG/PNG at the same visual quality. Resize before upload. Don't serve a 4000px-wide photo in a 600px container. Use loading="lazy" on below-the-fold images so the browser doesn't fetch them until needed. Add explicit width and height attributes to prevent layout shift (this also helps your Cumulative Layout Shift score). <img src= "/project-thumb.webp" alt= "Project screenshot" width= "600" height= "400" loading= "lazy" /> 3. Minimize and Defer JavaScript Ship only the JS a page actually needs — code-split per route if your framework supports it. Defer non-critical scripts (analytics, chat widgets) with defer or load them after the page is interactive. Audit your bundle with a tool like source-map-explorer or your framework's built-in bundle analyzer to catch unexpectedly large dependencies. 4. Nail the SEO Basics Good perf
When I checked Google Search Console after a month, only 2 of my 8 sites were indexed. The other 6 had zero pages in Google's eyes. No penalty, no error banner. Just silence. The bug My build script generated the sitemap by mapping over page objects. Somewhere a URL field was an object, not a string. So the sitemap shipped lines like: <url><loc> https://example.com/[object Object] </loc></url> Google fetched the sitemap, saw garbage URLs, and quietly skipped the whole file. No crawl, no index. How I caught it GSC > Sitemaps > it said "Success" but "Discovered pages: 0". That mismatch is the tell. I opened the raw sitemap.xml in the browser and searched for [object . There it was. Root cause: url: page.url where page.url was itself { path, params } , not a string. The fix // before loc : page . url // -> [object Object] // after loc : `https://livephotokit.com ${ page . path } ` Redeployed, resubmitted the sitemap, and requested indexing on the core pages. Pages started landing in the index within a couple of days. Takeaway A "Success" status on your sitemap does not mean Google read your URLs. Always open the raw XML and eyeball it. One bad [object Object] can silently sink an entire site. I'm building LivePhotoKit and a handful of other small tools solo with AI. Sharing the real bugs as I hit them.
Every developer has that one project. The passion build that sits in the back of your mind for months—or even years—before you finally sit down, crack your knuckles, and make it a reality. For me, that project was building a modern, open-access bilingual digital lexicon bridging English and Assamese: AssameseDictionary.org . While it started as a personal milestone dream, it quickly turned into a massive data engineering and architecture challenge. Here is how I tackled parsing a massive vocabulary database and serving it globally with near-zero latency. 🏗️ The Core Challenge: Scale vs. Speed A dictionary isn't like a standard SaaS app or landing page. It lives and dies by its database depth. To make this a truly definitive tool, I compiled, cleaned, and programmatically validated an extensive vocabulary index mapping over 293,000 words . The dataset doesn't just hold simple translations; it maps complex bidirectional lookups, phonetic transliterations, advanced English definitions, context usage examples, and cross-linked synonym tokens. If I threw this massive dataset into a traditional relational database hooked up to a standard server setup, I ran into immediate roadblocks: Latency: Heavy search queries on a dataset this size can cause noticeable lag. Cost/Overhead: Maintaining and scaling database servers for unpredictable public traffic gets expensive fast. I wanted the search utility to snap back instantly. To achieve that, I had to ditch traditional server paradigms entirely. ⚡ The Architecture: Serverless Edge Caching To keep things ultra-lightweight, highly cost-effective, and blazing fast, I built the platform around an edge-computing topology: The Runtime: I offloaded the backend logic entirely to Cloudflare Workers . Instead of routing traffic to a centralized origin server, queries are intercepted and executed at serverless edge locations physically closest to the user. The Data Layer: Instead of an active SQL database bottleneck, I mapped the data mat
Using AI to find authorization bugs — and to prove the ones that aren't real Draft flagship post. Safe to publish now (no undisclosed vulnerabilities). The production case study referenced at the end is withheld pending coordinated disclosure. In 2026, bug bounty programs started closing their doors. Nextcloud suspended paid rewards, citing a flood of AI-generated, low-quality reports. Mattermost ended its program. The Internet Bug Bounty cut payouts by roughly 80%. The common thread isn't that AI can't find bugs — it's that most AI-assisted "findings" are plausible but wrong , and triage teams are drowning in them. That reframes the problem. The scarce skill in 2026 isn't generating candidate vulnerabilities — a language model will hand you fifty before lunch. It's refuting the forty-nine that don't hold . The differentiator is a method whose primary output is correct negatives . Here's the method I use for source-available targets, and a worked example where the honest result was "there's no bug here." The method: fan out to find, converge to refute Two stages, two different cost tiers: Fan-out (cheap models). Split the target's authorization surface into subsystems and read each in parallel. Each reader's only job is to surface candidate broken invariants — places where an object is loaded by ID without an owner check, where a protected action might skip a re-auth gate, where two code paths authorize the same thing differently. Optimize for recall. Expect mostly false positives. Adversarial verification (an expensive, high-reasoning model). Take each candidate and try to kill it. Default to REFUTED. A candidate survives only if you can cite the specific source lines proving the guard is absent and the dangerous path is reachable and nothing upstream already blocks it. Frame every survivor as a broken invariant — a one-sentence statement of the rule the system must never violate — and classify it as core versus config-dependent. The output that matters most is the
Introduction to Hydration and Rendering Strategies In the relentless pursuit of faster, more responsive web applications, developers have engineered a spectrum of hydration and rendering strategies . Each approach emerges as a response to specific performance bottlenecks, yet none is universally optimal. This section dissects the core mechanics of these strategies, their historical evolution, and the critical problem they aim to solve—balancing speed with practicality. The Problem: A Trade-Off Landscape At its core, the challenge is mechanical : how to deliver content to the user’s browser with minimal latency while maintaining interactivity. Traditional rendering methods (e.g., server-side rendering) prioritize initial load speed but often defer interactivity until JavaScript execution. Client-side rendering, conversely, delays the first paint but ensures seamless interactions post-hydration. The tension between these extremes has birthed hybrid strategies like incremental hydration and islands architecture , each addressing specific failure points in the rendering pipeline. Key Mechanisms Driving Strategy Evolution Advancements in Web Technologies : New APIs (e.g., Web Components, Streaming SSR) enable finer-grained control over rendering. For instance, streaming SSR reduces Time-to-First-Byte (TTFB) by sending HTML in chunks, but risks breaking the causal chain of DOM hydration if not synchronized with client-side scripts. User Expectations : Sub-second load times are no longer aspirational but expected. This pressure deforms traditional workflows, pushing developers toward pre-rendering or static site generation (SSG), which trade dynamic flexibility for speed by offloading rendering to build time. Competitive Pressure : Performance is a zero-sum game. Companies adopt strategies like partial hydration (hydrating only interactive components) to minimize JavaScript payload, but this risks breaking interactivity if the hydration boundary is misaligned with user int

Working With Massive JSON Responses Without Losing Performance Every developer eventually encounters it. You make an API request expecting a few hundred objects, and instead receive a response that's tens—or even hundreds—of megabytes. Suddenly your browser freezes, your editor becomes sluggish, and your application consumes gigabytes of memory. Large JSON responses aren't unusual anymore. Analytics platforms, cloud providers, search engines, AI services, ecommerce catalogs, IoT systems, and data export endpoints routinely generate enormous payloads. The good news is that handling massive JSON efficiently is mostly about choosing the right techniques. This guide covers the best practices that help you inspect, process, and optimize large JSON datasets without overwhelming your tools or your users. Understand Why Large JSON Is Expensive Before optimizing, it's helpful to know where the cost comes from. When an application receives JSON, it usually goes through several stages: Download the response. Store it as a string. Parse it into objects. Allocate memory for every property. Traverse the resulting object graph. For a 100 MB JSON file, peak memory usage can easily exceed 300 MB because both the raw string and the parsed objects coexist temporarily. This explains why applications often run out of memory long before reaching the actual file size. Don't Pretty-Print Gigantic Responses Immediately Pretty-printing is useful—but formatting a huge document all at once can consume significant CPU time and memory. Instead: inspect only the sections you need collapse large objects expand nodes on demand search before formatting If you need to examine a large payload in the browser, using a dedicated formatter designed for large documents can make navigation much easier. Tools like JSON Formatter allow you to validate, format, collapse, and inspect JSON without manually editing thousands of lines. Stream Instead of Loading Everything One of the biggest mistakes is reading an
