Show HN: Decomp Academy – Learn to decompile GameCube games into matching C
Over the past few months I've been heavily involved in the decompilation community. I've been hands-on decompiling a beloved game from my childhood (Star Fox Adventures). I started this journey with zero prior decomp experience—and to make things worse I had never really touched C nor assembly either. Learning how to decompile was challenging. It's difficult to find any good learning resources for it and any open-source projects for this are inactive and/or contain little actual learning materia

Polymarket Hack: How Third-Party Vendors Risk Your Crypto
What We Know: The Basics of the Breach Polymarket, one of the largest prediction market platforms in the crypto space, confirmed on X that hackers stole funds from users after attackers compromised a third-party vendor. The breach allowed the attackers to inject malicious code directly into Polymarket's website, though the company specified the code ran "for some users" — a detail that raises immediate questions about whether the attack was deliberately targeted or only partially executed before detection. Polymarket spokesperson Connor Brandi confirmed to TechCrunch that the vendor compromise resulted in direct theft of user funds. Beyond that confirmation, the company declined to answer specific questions about the incident, leaving the scale of the financial damage, the identity of the compromised vendor, and the exact mechanism of the malicious code injection all officially unaddressed. The platform says it has contained the breach and is reaching out directly to affected users, committing to full refunds. No figure for total stolen funds has been disclosed. Blockchain monitoring firm PeckShield flagged suspicious activity around the same time Polymarket made its public announcement, adding an independent layer of confirmation that something significant moved on-chain during the incident window. What stands out immediately in the crypto security community is where the failure originated. The Polymarket platform itself was not the direct point of entry — a third-party vendor was. That distinction matters enormously. Users who trusted Polymarket's smart contract security and on-chain transparency had no visibility into the web infrastructure dependencies sitting between them and the prediction market interface. The malicious code injection attack, a technique that exploits trusted website supply chains, bypassed the decentralized architecture that crypto platforms often promote as a security feature. The incident joins a growing list of Web3 platform breaches wher
Show HN: QR code renderer in a TrueType font
In the "Libre Barcode Project" discussion yesterday, 1bpp asked: "Is anyone willing to sacrifice their sanity for the sake of implementing a QR renderer as TTF hinting code?" Yes. I had some tokens to burn and was curious... turns out, it's possible. This was put together by a mix of Gemini, GPT, and Claude (depending on which usage limits kept running out).

Show HN: Engye – transfer files between any two devices by scanning a QR code
Early in April I needed to print some tax forms at the library, first time in forever, and I began to wonder: what's the easiest way to get a file onto a public computer? There are many ways, but most of them involve creating an account somewhere or plugging in a thumb-drive. I use a password manager, so my passwords are long and complicated, not easily typed. I don't want to plug anything into a public computer, nor do I fancy uploading my taxes to some random website. I thought about what a he
Set per-customer send quotas with agent policies
Most multi-tenant email-agent setups give every customer the same caps. Your free-tier user who signed up an hour ago and your enterprise account doing thousands of sends a day hit the exact same daily send limit, the exact same storage ceiling, the exact same retention window. That's fine right up until a free trial account starts hammering your infrastructure, or an enterprise customer files a ticket because their agent stopped sending at noon UTC and nobody can explain why. Free-tier and enterprise tenants shouldn't share the same caps. They have different risk profiles, different contractual obligations, and different billing. The trick is to make the quota a property of the tier, not a property of each individual account — so when you provision a new tenant you don't compute limits, you just drop them into the right bucket and the limits come along for free. With Nylas Agent Accounts that bucket is a workspace , and the caps live on a policy you attach to it. Set up one policy per tier, attach each to its tier's workspace, and every Agent Account in that workspace inherits the policy's send, storage, and retention limits automatically. No per-account configuration, no drift. I work on the Nylas CLI, so the terminal commands below are the exact ones I reach for when I'm wiring this up. As always, I'll show both the raw HTTP call and the CLI equivalent for every step, because half of you live in scripts and the other half live in your app code. What you actually get An Agent Account is just a Nylas grant with a grant_id — a managed mailbox that can send and receive on a domain you've registered. Everything grant-scoped works against it: Messages, Drafts, Threads, Folders, the lot. There's nothing new to learn on the data plane. A policy is a reusable bundle of limits and spam settings. One policy can govern many accounts. The limits we care about for tiering are: limit_count_daily_email_sent — how many messages an account can send per day. limit_storage_total — t
I Built a Unit Converter in Pure Vanilla JS — 7 Categories, 70+ Units, 165 Tests, Zero Dependencies
Unit converters are everywhere online, but they all seem to either require an account, run ads that cover half the screen, or send your input to a server for no reason. I built one that runs entirely in your browser, with no dependencies, no tracking, and no round-trips. 👉 https://unit-converter-dev.pages.dev What It Does Seven conversion categories, 70+ units, real-time bidirectional conversion: Category Example units Length mm, cm, m, km, in, ft, yd, mi, nmi, light-year Weight mg, g, kg, t, oz, lb, st, short ton Temperature °C, °F, K, °R Volume ml, l, m³, fl oz, cup, pint, quart, gallon, tbsp, tsp Area mm², cm², m², km², ha, acre, ft², in², mi², yd² Speed m/s, km/h, mph, ft/s, knot, Mach Data bit, byte, KB/KiB, MB/MiB, GB/GiB, TB — both SI and binary Features: Bidirectional — type in either field, the other updates instantly Swap button — flip from/to with one click All-units panel — see your input converted to every unit in the category simultaneously Formula display — shows the conversion factor (e.g. "1 Mile = 1.609344 Kilometer") Zero dependencies — single HTML file, no build step, no npm Implementation Notes Linear vs. non-linear conversions Most unit conversions are linear: multiply by a factor to get to the base unit, divide by another factor to get to the target. The approach: function convert ( catKey , fromUnit , toUnit , value ) { const base = toBase ( catKey , fromUnit , value ); // → base unit return fromBase ( catKey , toUnit , base ); // base unit → target } function toBase ( catKey , unit , value ) { const u = CATEGORIES [ catKey ]. units [ unit ]; if ( u . toBase ) return u . toBase ( value ); // non-linear (temperature) return value * u . factor ; } Temperature is the classic non-linear case. You can't just multiply to convert between Celsius, Fahrenheit, and Kelvin — you need offset arithmetic: temperature : { units : { C : { toBase : v => v + 273.15 , // °C → K fromBase : v => v - 273.15 , // K → °C }, F : { toBase : v => ( v - 32 ) * 5 / 9 + 2

DeepSeek's DSpark Brings Speculative Decoding Back Into the Spotlight — Here's What Developers Need to Know
Introduction Speculative decoding is one of those techniques that has been "almost ready for production" for the better part of three years. A small draft model proposes tokens; a larger target model verifies them in a single forward pass. In theory, you get 2–4× throughput. In practice, the draft model has to be cheap, fast, and good enough at mimicking the target's distribution, which is a much harder combination than it sounds. Yesterday, a new paper from DeepSeek quietly climbed to the top of Hacker News (714+ points, 290+ comments at the time of writing). It's called DSpark , and it reframes speculative decoding in a way that looks like it could finally make the technique drop-in rather than bolt-on. The paper is here: github.com/deepseek-ai/DeepSpec/blob/main/DSpark_paper.pdf The Core Idea Instead of training a separate, smaller draft model from scratch (the classic approach), DSpark grafts the speculative head directly onto the target model. The intuition is simple: if the target model already knows which tokens are likely to follow, why not reuse its own intermediate representations rather than maintaining a parallel network? From the discussion on HN, this approach has a concrete architectural benefit — it reduces layer duplication that you'd otherwise have to maintain with a standalone draft model. In the DeepSeek experiments, the technique was applied on top of Step and Qwen 3.6 , which are themselves MTP-capable. How It Fits With MTP One of the more interesting practical points raised by HN commenters: DSpark is complementary to Multi-Token Prediction (MTP) , not a replacement for it. MTP — where the model predicts several future tokens at every step using auxiliary heads — has already been shown to give 50–100% speedups on hardware like the NVIDIA DGX Spark. DSpark adds another layer on top: even with MTP, the validation step is still a single forward pass through the main model, and the speculative tokens that get accepted come "for free." A useful men
I Built an AI Tool That Emails Hiring Managers Instead of Clicking "Easy Apply"
Most job search tools focus on submitting more applications. I wanted to solve a different problem: reaching the people actually making hiring decisions. So I built PitchHired , an AI-powered platform that helps job seekers find hiring managers, generate personalized outreach emails, review them with AI, and send them from their own Gmail account on a business-hours schedule. The goal isn't to replace the job search, it's to remove repetitive work while keeping the candidate in control. I also chose a one-time credit model instead of monthly subscriptions because job seekers shouldn't have to keep paying while they're between opportunities. PitchHired is still evolving, and I'd genuinely appreciate feedback from fellow developers. What features would you want in a tool like this, and what would make you trust (or not trust) AI-assisted job search?
I Run a 21-Article Gaming Blog With Zero Coding — Here's My Tech Stack
I started a gaming guide blog six weeks ago. Twenty-one articles later, it's getting traffic from Google, I have four affiliate programs set up, and I have never written a single line of code. This is not a "how to make money blogging" post. This is a practical breakdown of the tools, the workflow, and the mistakes I made so you can skip them. The blog is yxgonglue.com. It covers PC and console game guides — GTA VI pre-order comparisons, VPN setups for gaming, cloud gaming platform rankings, extraction shooter loot guides. Niche stuff. The kind of content people search for when they have a specific problem. Here is the stack that runs it. THE STACK WordPress + Kadence Theme Hosted on a standard shared hosting plan. Kadence is a free WordPress theme that loads fast and does not fight you. No page builder. No Elementor. Just the block editor and Kadence blocks for tables and formatting. The biggest lesson here: your theme does not matter as much as your content structure. Pick something lightweight. Stop theme-shopping. Start writing. Yoast SEO The free version. It gives you a red/yellow/green score for each post based on keyphrase density, subheading distribution, link count, and meta length. Is it perfect? No. Is it a useful checklist for someone who does not do SEO for a living? Absolutely. One thing Yoast taught me the hard way: Custom HTML blocks are invisible to the plugin. If you paste your article into a Custom HTML block, Yoast reads zero words, zero links, zero headings. Everything turns red. Use the regular editor. If you need a table, use a table block. Keep it simple. Google Search Console This is where you see what people actually searched before they clicked your article. The gap between what you think people search for and what they actually search for is enormous. Search Console closes that gap. Submit every new post URL manually. It takes ten seconds. Do not wait for Google to discover your site on its own. THE CONTENT WORKFLOW One Article Per Day Tw
CDP Browser Control: Driving Real Chromium from Python
Playwright and Selenium are great until you hit bot detection. Google OAuth, Cloudflare, and Vercel checkpoints all flag headless browsers. Here's how to control a real Chromium instance via CDP using Python and websockets. Why Not Playwright? Playwright launches a headless browser with automation flags. Even in headed mode with Xvfb, Google detects it. The CDP Approach Launch Chromium with remote debugging: chromium-browser --user-data-dir = /path/to/profile --remote-debugging-port = 9222 --no-first-run Connect via WebSocket in Python: import asyncio , json , websockets , urllib . request async def get_page_ws (): resp = urllib . request . urlopen ( ' http://localhost:9222/json ' ) targets = json . loads ( resp . read ()) for t in targets : if t [ ' type ' ] == ' page ' : return t [ ' webSocketDebuggerUrl ' ] async def cdp_call ( ws , method , params = None ): msg_id = cdp_call . id = getattr ( cdp_call , ' id ' , 0 ) + 1 msg = { ' id ' : msg_id , ' method ' : method } if params : msg [ ' params ' ] = params await ws . send ( json . dumps ( msg )) while True : resp = json . loads ( await ws . recv ()) if resp . get ( ' id ' ) == msg_id : return resp Key Advantages Real browser fingerprint, no automation flags Persistent sessions, cookies survive across runs Google OAuth works, existing sessions carry over No bot detection, it IS a real browser Follow for more tutorials on browser automation and AI agent architecture.

Building AI-Native Frontends with Claude Code and MCP
Headline: The wins come from context, not cleverness. An AI with your codebase, your design system, and your deploy logs in scope writes code that ships. Without that scope, it writes plausible code that doesn't. Two years ago, AI coding tools were autocomplete with attitude. In 2026 they are a credible second engineer — provided you build the workflow around them. This is the workflow I run today at Devya Solutions and on personal projects like eng-ahmed.com . The Stack Claude Code in the terminal — long-horizon, multi-file edits with skills and subagents. MCP (Model Context Protocol) servers for live access to docs, deployments, browser, and design tools. Cursor or VS Code for inline edits when I want to stay in the IDE. Why Context Is Everything The single highest-leverage move in AI-assisted dev is feeding the model the right context. MCP servers do this without prompt stuffing. Docs MCP — pulls current library docs at call time, so the model doesn't hallucinate the Tailwind v3 API in a v4 codebase. Browser MCP (Claude-in-Chrome) — lets the agent open the running dev server, screenshot the page, and verify the change actually rendered. Vercel MCP — fetches deploy logs and runtime errors directly. No more pasting logs. Context-mode MCP — keeps file scans, search results, and command output in a sandbox, only surfacing what's relevant to your conversation. A Real Workflow The blog page redesign I just shipped was built in a single 45-minute session. Rough flow: State the goal — two sentences, not a spec doc. Let the agent scout — Claude Code greps, reads a few files, proposes a plan. Iterate visually — screenshot the result, feed it back. The agent fixes the sticky-filter scroll bug in one turn. Commit and push — a single cm shortcut runs build, commits, and pushes. Vercel deploys on push. What the Agent Is Still Bad At Holistic taste — it copies the closest example in your codebase. If that's mediocre, the new feature is mediocre. Domain knowledge — it doesn't kn
