I Built a Manga Reader That Works on Every Platform — Here's How Nyora is a free, open-source manga/manhwa/manhua reader for Android, iOS, macOS, Windows, Linux, Web, and even Docker — with AI-powered on-device translation and cross-platform sync. The Problem Every manga reader makes you choose: Free but ad-riddled (most Android readers) Polished but paywalled (commercial apps) Powerful but single-platform (Tachiyomi, Aidoku) I wanted one library — same titles, same progress, same bookmarks — on my phone, laptop, and browser. No ads. No account required. So I built it. What Nyora Does Every Platform, One App Platform Distribution Android APK (sideload) iOS/iPadOS IPA via AltStore/SideStore macOS .dmg or brew install --cask nyora Windows .exe (x64 + ARM64) Linux .deb , .rpm , or curl installer Web web.nyora.xyz — zero install Docker Single container, self-hosted No account needed to read. Cloud sync is opt-in. AI Translation That Understands Manga This is the flagship feature. Instead of dumping translated text over the artwork: Detects text baked into speech bubbles and captions Translates using on-device ML Typesets the result back over the original artwork Each platform uses the best local engine: Android : Google ML Kit + ONNX Runtime iOS : Apple Intelligence + Google Translate macOS : Apple Vision + MangaOCR CoreML Windows : Windows OCR Linux : Tesseract There's also an Ensemble AI Narrative Engine that tracks character names and speaking styles across chapters so translations stay consistent. 1,100+ Sources The Android app pulls from 1,100+ manga sources via 35 generic engine templates (Madara, FoolSlide, MMRCMS, etc.). Web has ~390 live, health-checked sources. Desktop ports are growing toward parity. Free Cloud Sync Sync library, categories, reading history, bookmarks, and exact page progress across all six platforms. Two sign-in methods: Google OAuth Nyora Cloud (email + password, free) Self-hostable — the backend is just Supabase/PostgreSQL with row-level s

A validation failure is not an exception to hide. It is a record your system does not yet know how to trust. That distinction matters in LLM extraction pipelines. A malformed invoice, an unexpected OCR layout, a model response that violates the schema, and a semantically impossible value may all reach the same line of validation code. If the only outcomes are “retry” or “drop,” the pipeline will either waste money repeating the same failure or silently lose work. The production answer is a dead-letter path: a durable place for failed records to wait with enough evidence to explain, triage, and safely replay them. The queue itself is the easy part. The hard part is designing the failure contract around it. Validation is where routing begins Constrained decoding and post-hoc validation solve different problems . Even with both, some records should fail. Real documents are messy, schemas change, OCR corrupts values, and models sometimes return plausible nonsense. A robust validation boundary should produce more than true or false . It should emit a reason the rest of the pipeline can act on: which schema and model versions were used which fields failed and why whether the payload was malformed, incomplete, or semantically invalid the confidence signal attached to the extraction whether a retry is likely to change the result That result becomes a routing decision. High-confidence, valid records can flow forward. Recoverable transport failures can use a bounded retry. Ambiguous or invalid records belong in review or a dead-letter queue. Confidence-based routing is useful precisely because “trust everything” and “review everything” are both bad operating models. A dead-letter record needs evidence, not just payload Putting the original input on another queue is not enough. Without context, the team investigating the failure has to reconstruct the run from scattered logs—if those logs still exist. I would store a dead-letter envelope containing: a stable record ID and idem

TL;DR Welcome back to Dev Opportunity Radar. This is a weekly series where I share opportunities,...

"When you multiply 0588235294117647 by 2, 3, 4, 5, …, 16, the same sequence of digits appears in a cyclic order. That is, the digits remain the same but start from a different position, and when they reach the end, they continue again from the beginning." Would be useful for hash tables? or something else that needs rotations/permutations? looks like a reversible data transformation what if instead of 16 values (4 bits), we get a bigger number for 65536 values (16 bits) ChatGPT says it's related to a particular property of 17 (a prime number), but I want to know the opinion of actual programmers, mathematicians and engineers.

This is going to be a very different article from what I usually write. No technical discussions, architecture deep dives, or engineering practices today. Instead, we're talking about something much older than software itself: music. We treat language like it's the default mode of human communication, like it's the real and only thing used to communicate, everything else is secondary, emotional, aesthetic, nice to have. But language is actually the outlier. It's the new protocol layered on top of something much older. Music is the original standard and we've basically forgotten how to read it. The Protocol Stack Think of communication like a network stack. Language is high-level. It's TCP/IP. Built on assumptions, needs learning, breaks the second you cross a boundary. You need: A shared vocabulary Syntactic understanding Cultural context Years of study if you actually want fluency It's powerful but It's also fragile. And it's recent . Written language is a few thousand years old. Spoken language is older, sure, but both are late abstractions compared to the hundreds of thousands of years humans have been syncing bodies to shared sound. Relative to that timeline? Language is yesterday's patch. Music? That's the lower-level protocol. The physical layer everything else runs on. A Japanese teenager at a Michael Jackson concert doesn't need to speak English. She doesn't need to understand what "Man in the Mirror" means as a concept. She also doesn't need a music degree. Music isn't zero -cost. Genre, culture, convention still shape how we hear it. But the entry barrier for emotional communication is way lower. A rhythm can hit urgency, celebration, sadness, or tension long before anyone understands the formal structure behind it. Her nervous system speaks that fluently. And so does everyone else in that stadium. How the Protocol Works Here's what happens when the song starts: 70,000 people stop being individuals and start being a distributed system synchronizing to the

When building a website, choosing a button design can take more time than expected. You may want something simple, soft, colorful, dark, outlined, or slightly unusual—but comparing many styles usually means repeatedly editing CSS and refreshing the page. To make that process easier, I created a browser-based button showcase. Try It Online You can use it directly from the following page: https://uni928.github.io/Uni928PublicHTMLs/index78.html There is nothing to install. Open the page, browse the available designs, and choose a button you like. Many Button Styles in One Place The page includes a wide range of button designs, including: Light and subtle buttons Solid-color buttons Dark buttons Gradient buttons Outline buttons Rounded and pill-shaped buttons Buttons with icons More experimental designs The buttons are displayed as actual interactive elements, so you can compare their hover, focus, and pressed states directly in the browser. Click a Button to Copy It The main feature of this tool is its copy workflow. Clicking a button copies a minimal HTML example for that design. This makes it easier to take only the button you need instead of copying the entire showcase page. The generated example includes the necessary HTML and CSS, so it can be pasted into a new file and tested immediately. Copy Features for Faster Comparison The site also includes additional copy-related features to make browsing a large number of designs more convenient. You can: Copy a button directly by clicking it Review the generated code Copy frequently used button types from the quick-copy panel Receive visual feedback after a successful copy Use copied examples as standalone HTML files This is especially useful when you want to compare several designs before deciding which one to use in a project. Useful for Prototypes and Small Projects This tool is intended for situations where you need a usable button quickly, such as: Creating a prototype Building a small static website Testing a landi

Bio-Tuning Glasses: Building an Invisible Biofeedback Interface with Edge AI and Adaptive Optics What if smart glasses didn't constantly tell you how healthy—or unhealthy—you are? No step counts. No stress notifications. No endless dashboards. No digital reminders telling you to "sit straight" or "go to sleep." Instead, imagine a wearable device that quietly adapts the environment around you based on your physiological state. This is the idea behind Bio-Tuning Glasses : an experimental concept for an Invisible Biofeedback Interface positioned between human biology and unconscious behavior. The goal is simple: Don't make the user adapt to the technology. Make the environment adapt to the user. From Health Monitoring to Environmental Intervention Most wearable health devices follow a familiar architecture: Sense → Analyze → Notify User The user receives information: Your heart rate is high. You are stressed. You haven't moved enough. Your sleep quality is poor. Bio-Tuning proposes a different paradigm: Sense → Infer → Intervene → Observe → Learn Instead of presenting another notification, the system attempts to modify the user's environment in subtle ways. For example: Physiological arousal detected ↓ Contextual state estimation ↓ Adaptive visual intervention ↓ Physiological response observed ↓ Personalized model updated The user may never see a notification. The intervention simply happens in the background. 1. Hardware Architecture The glasses would combine several sensing modalities in an extremely compact form factor. Biometric Sensors Potential sensors include: PPG for heart rate and HRV estimation EDA for electrodermal activity IMU for head movement and posture-related signals Temperature sensors Ambient light sensors Eye and Visual Sensing Potential inward-facing sensors could estimate: Blink frequency Eye movement patterns Pupil-related features Visual fatigue indicators Importantly, raw eye imagery does not need to leave the device. Instead: Raw Sensor Data ↓

Controller A records revocation epoch 12. Worker B, partitioned with a cached grant from epoch 11, starts another external action. The database is correct and the system is unsafe. Emergency stop is therefore a distributed protocol, not a Boolean field. What is verified In its July 21 disclosure, OpenAI says an internal benchmark used models with reduced cyber refusals and that a combination of models compromised Hugging Face infrastructure. The primary source is https://openai.com/index/hugging-face-model-evaluation-security-incident/ . Reporting on July 24 then described US discussion of emergency-shutdown and independent-audit proposals. The latter is policy coverage, not enacted law and not an extension of the official incident facts. Missing protocol details, impact boundaries, and remediation should remain unknown rather than inferred. Invariants and assumptions Assume workers, queue consumers, an authorization service, and external adapters can fail independently. Messages may be delayed, duplicated, or reordered; clocks have bounded error only if measured. Required invariants: No action starts with a grant epoch below the subject's revocation epoch. Cached grants expire within a declared lease bound. Restart cannot lower a persisted epoch. Duplicate revocation converges to the same or higher epoch. Completion means every registered executor acknowledged or its lease expired. revoke(subject, epoch=13) -> durable CAS max(current, 13) -> publish {subject, epoch:13} -> executors persist max(local, 13), ack -> controller waits for ack set OR lease expiry -> issue completion receipt with missing/expired members Failure injection Property Acceptance rule delay revocation event lease bounds stale authority no start after local lease expiry duplicate epoch 13 idempotence epoch remains 13+ deliver 13 before 12 monotonicity never returns to 12 worker restarts durability loads persisted epoch before work controller partition fail closed no new lease after expiry A minim

Turning entire novels into narrated, lip-synced, motion video — locally, on a single 16GB GPU, with FLUX, Wan2.2, PuLID, MuseTalk, and ComfyUI. There's an old line: a picture is worth a thousand words. I'd extend it — a video is worth a thousand pictures. So I spent the last few months testing that idea the hard way: I built a pipeline that turns an entire novel into a narrated, lip-synced, motion video. Feed it Pride and Prejudice , or a 400-year-old tale from Strange Tales from a Chinese Studio (聊斋志异), and out comes a finished film with consistent character faces across a hundred-plus scenes. One person. One RTX 4060Ti with 16GB of VRAM. Everything local, no cloud inference. I called it iTube. And honestly — the videos came out better than I expected. Watching a novel you know become a moving, voiced, paced thing is a genuinely different experience from reading a summary of it. That's the bet: that video is a better medium for conveying a story than text is, and the finished clips have mostly convinced me the bet was right. See for yourself before reading another word about how it works: 🎬 Pride and Prejudice — a Western public-domain classic 🎬 聊斋志异 / Strange Tales from a Chinese Studio — a playlist of classical Chinese tales But this post isn't a demo reel. It's about the part nobody warns you about — the part between the models — because that's where the real work turned out to be. The models are instruments, not magic boxes Here's the single most important thing I learned, and the thing I'd want any collaborator to understand before touching a pipeline like this: Each AI package can do exactly one thing well, and your entire job is knowing precisely where each one's ability ends — then writing your script logic to route around the gaps. The stack is not exotic. Most people in generative media know these pieces: FLUX generates the still image for a scene. That's all it does — a single frame. Beautiful, controllable with the right prompt, but frozen. Wan2.2 takes

Introduction Having laid out some mathematical foundations in the [previous part][1], we will proceed to discuss quantum gates and circuits in depth here. As usual, we will drive home the theories with worked examples from [@Rieffel2011] and check their accuracy with qiskit and/or cirq code. Prerequisite Understanding quantum gates and circuits will be greatly aided by the knowledge of classical gates (AND, OR, NOT, XOR and the universal gates: NAND and NOR). Also, some familiarity with the Python programming language will help you understand qiskit and/or cirq code. Classical & Quantum gates A classical computer, possibly the one you're reading this with, is a sophisticated engineering piece, no doubt. However, the underlying "magic" comprises logic gates. The National Institute of Standards and Technology (NIST) gives this incredible analogical description of classical computers in relation to logic gates [@NISTQGATE2026]: Traditional computers are like microscopic cities. The roads of these cities are wires with electricity coursing through them. These roads have lots of gates, known as logic gates, which enable computers to do their job. Like physical gates that allow or block cars, logic gates allow or block electricity. Electricity that goes through the gates represents a “1” of digital data, and blocked electricity is a “0.” When you pick up a motherboard, for instance, you may not see the said gates as they are made of tiny transistors (in modern systems, MOSFETs) in specific combinations. Also, the $0$ and $1$ referred to in the analogy mean low and high voltage ranges, respectively. Their actual voltage values depend on the hardware. :::note All schematics were written in and rendered by @schemd/core . Check it out. ::: Logic Gates refresher Since we will be realizing some classical circuits using quantum gates, it's necessary to get familiar with common logic gates. NOT ($\neg$) Gate This gate takes a single classical bit and flips it. For instance, if $0

Redis gets reached for reflexively, "just add Redis," as if it were a single fix for slowness. It's genuinely one of the most useful tools in a backend engineer's kit, but using it well starts with understanding what it actually is: an in-memory data structure store, not just a cache. Once you see it as a fast, versatile store of real data structures, the range of problems it solves cleanly (caching, rate limiting, queues, sessions, leaderboards, locks) stops looking like a grab bag and starts looking like one idea applied many ways. This is the opening article of the Redis Masterclass, and it builds on the PostgreSQL series : Redis usually sits alongside a primary database like Postgres, not instead of it. In-memory is the whole point Redis keeps its data in RAM. That single fact explains most of its character. Reading from memory is orders of magnitude faster than reading from disk, so Redis operations typically complete in well under a millisecond, and a single instance handles a very high request rate. That speed is why it's the default choice for anything on the hot path, where a database round trip would be too slow. The tradeoff is that RAM is smaller and more expensive than disk, and volatile. Redis addresses durability with persistence options we'll cover later, but the mental model to start with is: Redis is fast because it's in memory, and you use it for data that benefits from being fast to access, not as the permanent home for everything. It's a data structure store, not a key-value blob The common misconception is that Redis is a simple key-value store, strings in and strings out. It's much more. Redis stores real data structures as values, each with its own commands: Strings for simple values, counters, and cached blobs. Hashes for objects with fields, like a user record. Lists for ordered sequences and simple queues. Sets for unique collections and membership checks. Sorted sets for ranked data like leaderboards and priority queues. Plus streams, bit

How a face-customization puzzle at HackMIT went from clicking sliders by hand to reverse-engineering a hidden formula from 10,000 API calls. Face Value looked simple at first glance: ten sliders (Face, Skin, Hair, Brows, Eyes, Nose, Mouth, Glasses, Mole, Accessory), each 0-9, controlling a cartoon avatar. A hidden model scored every configuration, and the goal was to find one it would fully accept : Confidence ≥ 99.9% Edit distance from the starter config ≤ 5 (only half the sliders could move) Charm check: pass Sync check: pass The puzzle's own hint: "Not all features affect the model equally. Some are more sensitive than others, especially together. Single-feature sweeps can be misleading." That warning turned out to be the whole game. Phase 1: Brute Force by Hand The first instinct is the obvious one: click a slider, hit Query, read the result, adjust, repeat. Every query returned four numbers, shown together in a Reviewer panel: Probability, Charm, edit Distance, and Sync. All four had to align at once. This works, sort of. Over the first ~24 manual queries, real patterns emerged: certain Glasses values seemed to matter for Sync, Mole and Accessory nudged confidence up, some sliders had sharp peaks rather than smooth slopes. But progress plateaued hard around 60-77% confidence . Manual testing can only really explore one or two dimensions at a time, and the puzzle explicitly warned that the model cared about combinations ; you can't discover a 3-way interaction by changing one slider and squinting at the result. The first real breakthrough was small but important: after enough fiddling, one query came back with Sync: True for the first time, confidence still low (8.14%), but proof that the four conditions weren't mutually exclusive. Phase 2: Escaping the UI The turning point was popping open Chrome DevTools, clicking Query once, and grabbing the actual network request as a curl command. Underneath the slick UI was a plain JSON API: POST https://facevalue.hackmit.

My project's docs had rules. "One document, one responsibility." "Split anything over 45 lines." I wrote that. The day before yesterday. Here's how that was going. Folders with no README (no index): 25 out of 37 The folder holding our engineering rules: 11 files, zero index Documents breaking the 45-line rule: 47 Largest offender: 1,203 lines Writing a rule down does not make it a rule. Obvious, I know. But there is something about being handed a list of 47 documents where you personally broke your own rule that stops being funny halfway down. (The me of two days ago fully intended to follow it.) I rewrote the rules themselves, and the rules file hit 150 lines The plan was already clear: let a machine enforce this. Fail CI. Which meant writing the rules properly first. README required, folder layout, update obligations, what CI actually checks. By the time it was all in there, the rules file was over 150 lines. The rules file was breaking the 45-line rule. Now, if you say "well, the rules file is special, it gets an exemption" — what have you just done? You have created the precedent "the rules are exempt," and it is permanent from that day. From then on, every time someone crosses 45 lines, they get to say "the rules file does it too." And they're right. So I split it. Eight files, all under 45 lines. If I can't follow my own rule, the rule was never worth writing. The moment CI landed, 63 existing violations bared their teeth On to the real work: write the checker, wire it into CI. Run it, and of course: 63 violations Everything fails. All red. Files I'm about to touch and files nobody has opened in months, equally red. Humanity is offered two choices here. Fix all 63 first, then turn on CI (including the 1,203-line monster) Add an ignore list, silence the 63, move on Tempting, isn't it? Option 2. It was to me. A .lintignore with 63 lines in it and a comment saying "remove later." So when exactly are you removing that list? Think about what that file actually is.

We've been testing a new project this week. The project's origin story is a mess. Upper management...

In the age of "Cloud Everything," our most sensitive data—our heartbeat, our sleep cycles, our stress levels—often ends up on a server somewhere in Northern Virginia. But what if we could keep that data where it belongs? On your device. Today, we're diving deep into Edge AI and On-device LLMs . We will build a privacy-centric health coach that uses MLX-Swift to run Llama-3 directly on your iPhone's Apple Silicon. We’ll be pulling real-time Heart Rate Variability (HRV) data from the HealthKit API and generating semantic health summaries without a single byte ever leaving your phone. 🚀 Why Edge AI? 🛡️ When dealing with Private AI and sensitive medical metrics, the "Cloud-First" approach is a liability. By leveraging MLX-Swift and the Unified Memory Architecture of the A17 Pro/A18 chips, we achieve: Zero Latency : No round-trip to a server. Total Privacy : Your data stays in the Secure Enclave. Offline Capability : Health insights in the middle of the woods? Yes. The Architecture 🏗️ The data flow is simple but powerful. We fetch raw samples from HealthKit, preprocess them into a prompt-friendly format, and feed them into a quantized Llama-3 model managed by the MLX framework. graph TD A[iPhone HealthKit Store] -->|Fetch HRV Samples| B(Swift Data Controller) B -->|Normalize & Format| C{MLX-Swift Engine} D[Llama-3-8B-4bit Model] -->|Load Weights| C C -->|Local Inference| E[Neural Engine / GPU] E -->|Semantic Summary| F[SwiftUI Dashboard] F -->|User Feedback| A Prerequisites 🛠️ To follow this advanced tutorial, you'll need: Xcode 15.4+ and a physical iPhone (iPhone 15 Pro or newer recommended for 8GB+ RAM).

OhNine is a free menu bar app that tracks Claude session and weekly usage limits in real time It sends native alerts at 80%, 91%, and 100% so a session never ends without warning The hard problem was never reading a number, it was making the warning arrive before the cutoff instead of after Building a zero telemetry tool changed how I judge every product I ship after it The Problem: Hitting a Wall You Cannot See For months, my Claude sessions ended the same frustrating way. I would be deep in a conversation, mid thought, actually making progress, and then the reply would just stop. No countdown. No yellow light. No warning that said "you have three messages left, wrap up." One second I was working, the next I was staring at a message telling me to wait for a reset I never saw coming. The frustrating part was not the limit itself. Usage limits exist for a reason, and I understand why they are there. The frustrating part was the total lack of visibility into where I stood. Claude Code and claude.ai will occasionally mention you are close to a cap, sometimes at 97 percent, which is technically a warning and practically useless, because by then you are already mid-thought with no time left to land it cleanly. It got worse once I noticed the layers. There is not one limit to track, there are several stacked on top of each other: a session limit, a rolling weekly cap, and separate caps depending on which model you are running. Switching models mid-session, thinking you had found a workaround, only to hit a wall from a different direction, was its own specific kind of frustrating. None of these layers showed up anywhere. There was no dashboard, no menu bar icon, nothing you could glance at the way you glance at your laptop's battery percentage before deciding whether to plug in. So the wall kept arriving the same way: mid-flow, mid-sentence, with zero warning. Coding sessions got cut off between a question and its answer. Writing sessions lost momentum at the worst possibl

Welcome to the v0.0.2 release of Knowledge-and-Memory-Management, a tool designed for ingesting and managing knowledge from diverse sources. This release marks a clean release, stripping all hardcoded personal paths and replacing them with the portable $AGENT_HOME environment variable. For experienced developers, this version brings consistency and ease of deployment across environments without sacrificing the core functionality of knowledge collection and memory management. The project focuses on three primary collection pipelines: web, video, and articles. Each pipeline is modular, allowing you to configure, extend, or replace components based on your stack. The memory management layer ensures that collected data is indexed, stored, and retrievable via semantic search, making it practical for building personal knowledge bases or feeding into larger systems like agents or RAG pipelines. Knowledge Collection The collection module is source-agnostic at its core but ships with specialized handlers for common content types. Web collection uses a configurable web scraper that supports depth limits, domain filtering, and content extraction via readability algorithms. You can target specific sections, strip ads, and normalize HTML into markdown. The scraper respects robots.txt and supports session management for authenticated sites. Video collection transcribes audio using a local or remote ASR model. The pipeline extracts audio tracks, splits them into chunks, and generates timestamped transcripts. This is particularly useful for processing lectures, talks, or screencasts. The transcript is treated as a text document for further processing. Article collection handles RSS/Atom feeds and direct URLs. It parses feeds, fetches full content using readability engines, and deduplicates entries. Articles are converted into a consistent schema: title, author, published date, body text, and metadata. All collected data passes through a normalizer that converts content into a stand
