Bus + one-wheel last mile: range math that actually matches reality

I started treating a one-wheel like a folding bike replacement for a 3 km bus gap. The spreadsheet looked fine. Real life did not.## What broke my first estimates* Sticker range is not commute range. * Hills, cold mornings, and stop-and-go ate about 3% of the rated number on my route. I now plan at ~6% of brochure range and keep a buffer for a wrong turn. Weight shows up on stairs, not on paper. Carrying the wheel through a station twice a day mattered more than top speed ever did. Rain is a policy decision, not a gear decision. Some days I bail to transit. Pretending I will always ride made me resent the wheel.## A simple checklist I use now1. Measure your worst leg, not your best day.2. Count how many times you pick the wheel up per trip.3. Decide where you charge (home only vs. desk outlet).4. Set a weather cutoff before you are tired and annoyed.## DisclosureI work around electric unicycles professionally, so take this with that bias. I am still trying to optimize my own commute, not sell anyone a model.If you want plain spec tables while comparing wheels: https://www.kingsong.com/collections/electric-unicycle What would you add for mixed transit + one-wheel days?

I built a free whale tracker for Polymarket — here's what I learned

The problem: I kept missing big moves on Polymarket because I had no way to see what the biggest traders were betting on in real time. So I built WhaleTrack — a free, no-signup tool that shows you exactly what top Polymarket whales are buying and selling. What it does Live whale activity feed — see the last 40 trades from top wallets, updated on refresh Whale leaderboard — P&L, win rate, trade count for the biggest accounts No login, no ads, no fluff — just the data How it works The whole thing is vanilla HTML/CSS/JS deployed on Vercel with two serverless functions: /api/whales.js — hits the Polymarket leaderboard API, fetches position stats for each whale, calculates win rates from closed positions /api/activity.js — pulls recent trades for each whale wallet in parallel, filters out internal combo transactions (no title / zero price), and returns the 40 most recent trades The serverless layer solves CORS — Polymarket's data API doesn't allow browser requests, so everything goes server-side. Tech stack Frontend: Vanilla HTML/CSS/JS (zero dependencies) Backend: Vercel serverless functions Data: Polymarket public data API Deploy: Vercel (free tier) Biggest lesson Filtering bad data is half the work. The raw API returns combo trades and internal transactions that show up as "Unknown Market @ 0¢" — useless noise. Had to figure out which fields to check (title, price > 0) to strip them. Also: win rate calculation is tricky when most whales have unrealized profits. Showing "—" instead of 0% is more honest. Try it WhaleTrack → Also launched on Product Hunt today if you want to show some love: Product Hunt Built this in a weekend. Happy to answer questions about the Polymarket API or Vercel serverless setup.

"It’s just HTML and CSS. It’s too simple to post."

For a long time, I hesitated to share my work. I kept telling myself: "If I post a simple hero section, a basic Bootstrap grid, or a landing page clone, people will judge me. They’ll think I’m not a 'real' developer yet." But today, I saw a video of a developer who built a complete Netflix clone using only HTML & CSS in just 4 hours https://x.com/Aditwariii/status/1681403710457643009?s=20 . It made me stop and think. It’s easy to get so obsessed with complex frameworks, cloud architectures, and database optimizations that we begin to look down on the fundamentals. But here is the psychology of software engineering that we often ignore: Every master was once a beginner: The engineers managing complex distributed systems today started exactly where we are—struggling to center a div and fighting with CSS media queries. Shipping beats hiding: Building a clean, responsive interface in 4 hours shows speed, focus, and attention to detail. Those are core professional hygiene habits. Code is for humans, not just machines: Before we write APIs or database queries, we must master how a human being actually interacts with our interface. I’m letting go of the fear of being judged for "simple" things. From now on, I am building in public. Whether it’s a massive full-stack application or just a beautifully aligned hero section, it is proof of active practice and continuous momentum.

When Old Things Take On New Meaning in the Age of AI (Bite-size Article)

Introduction — On What I've Been Writing for Years This is a follow-up to my previous post on Claude and MCP . Just sharing some recent thoughts. Personally, I've always enjoyed keeping records and analyzing my own work. So for years, I've been logging my daily tasks, jotting down thoughts, hesitations, and impressions in notes. I've drawn on these records for reviews, analysis, and decisions on various projects. The tools have shifted over time — Evernote, Notion, Logseq, Taskuma, and so on — but the habit itself, of writing notes into some app or tool, has stayed with me for years. What Happened with MCP I recently wrote about connecting Notion and Google Docs through MCP, and the results have surprised even me. I won't repeat the details here since they're in that post, but ever since I introduced MCP, the flow of information has accelerated dramatically. In particular, I'd been accumulating reviews, task management notes, and brainstorms in Notion for years, and letting Claude read all of this has shifted the meaning of what I'd previously written. When I first started recording in Notion, it never occurred to me that it might be useful to AI. Of course — I had no way to imagine a time when AI would become this close to everyday life, used in this way. I was just writing for plain, analog reasons — "so I could look back later," "so I could organize my own thinking." But the moment MCP made it all readable, the feeling shifted. It's as if my past self comes forward to help my current self. Claude answers my current questions while drawing on the reasoning behind old project decisions, or on impressions I'd noted at the time. I've had moments like that more than once now. Thinking about it: the human brain's memory has limits — even the person who wrote something forgets it quickly. That's why I kept taking notes, leaving behind my thoughts and conclusions at each point in time as a record. And now, in the flow of conversation, AI reads from those records, distill

I built a compiler for how AI agents should write to you

I kept correcting AI agents in the same ways: "too long," "answer first," "use a diagram," "assume I know the jargon." Each correction improved the current exchange, but the preference was not represented as durable system state. I built /calibrate-comms to make that state explicit. It is an open-source skill inside an Obsidian vault, used by both Claude Code and Codex. The model: nine operational dials The skill does not try to discover a personality type. It calibrates nine choices that directly change how an answer is rendered: Dial Practical question Density Tight sections or full reasoning? Sequence Answer first or chronological build-up? Modality Prose or diagrams for relational content? Abstraction Concrete example or principle first? Tradeoff One recommendation or several options? Detail Main path or edge cases too? Jargon Define terms or assume expertise? Tone Casual, neutral, or formal? Context-giving Should the agent extract missing context or split an overloaded brief? Prior → calibration → directives The workflow has three stages: L1 PRIOR → L2 SAMPLE REACTION → COMPILE → CLAUDE.md hypothesis empirical override shared by both agents Quick mode asks one bespoke forced-choice proxy per axis. Those questions are deliberately labelled as proxies, not validated psychometrics. Deep mode must fetch the exact items from supported open-access instruments before use; if the source cannot be obtained, the skill stays in Quick mode and makes no validation claim. The prior is then challenged through pairwise samples. For sequence, the contrast looks like this: Build-up first: We traced the latency spike to N+1 queries, then found lazy loading in a loop—so the fix is eager loading. Answer first: Fix: eager-load the association. Why: lazy loading in a loop caused N+1 queries and the latency spike. The user's pick is revealed preference. If it contradicts the prior, the sample wins. The compiler is the useful part The final profile is not a score report. A deterministi

How We Actually Measure Whether an LLM's Output Is Good - BLEU, COMET and BLEURT

Hello, I'm Shrijith Venkatramana. I'm building git-lrc, an AI code reviewer that runs on every commit. Star Us to help devs discover the project. Do give it a try and share your feedback for improving the product. An AI model writes a paragraph. It sounds fluent. It looks convincing. But how do you know whether it's actually good? This deceptively simple question has occupied researchers for more than two decades. Long before ChatGPT, machine translation researchers faced exactly the same problem. Human evaluation was expensive, inconsistent, and painfully slow. If every new model required thousands of humans to compare translations, research would crawl. That necessity gave rise to BLEU , one of the most influential evaluation metrics in AI history. Years later, as language models became better at paraphrasing and reasoning, BLEU started to show its age. Researchers responded with learned metrics like BLEURT and COMET , which use neural networks to judge language much more like humans do. Interestingly, this mirrors software engineering itself. We first wrote simple unit tests, then integration tests, and today we increasingly rely on sophisticated observability systems. Evaluation metrics for LLMs have undergone a similar evolution. Let's see why. Before BLEU: The Evaluation Bottleneck Imagine you're building Google Translate in 2001. Every time your team improves the model, someone has to read thousands of translated sentences and score them. Suppose a single sentence pair takes only 20 seconds to judge. Evaluating 50,000 sentences would require nearly 280 human-hours . Now imagine dozens of experiments every week. Evaluation—not training—quickly becomes the bottleneck. Researchers at IBM, led by Kishore Papineni , introduced BLEU (Bilingual Evaluation Understudy) in 2002 to automate this process. Their idea was surprisingly simple: If a machine translation resembles what professional translators write, it's probably good. This became one of the most cited papers

Building a Slack Bot That Actually Remembers: slacktag-oss

How I built an open-source Slack assistant with persistent semantic memory, powered by any LLM and Mem0's managed memory layer — no vector database required. The problem with Slack bots and memory Most AI Slack bots have the memory of a goldfish. Every conversation starts from scratch. You ask it about your sprint goals, it gives a great answer, then three days later you ask a follow-up and it has no idea what you're talking about. You end up re-explaining context constantly. The commercial solution to this is Claude Tag — a Slack integration that maintains genuine conversational continuity. But it's tied to one provider and not open-source. slacktag-oss is our attempt to replicate that experience: a Slack bot with real, semantic, persistent memory that works with any LLM — including ones running entirely on your laptop. What I built A Python Slack bot with: Socket Mode for local dev (no public URL needed), HTTP-ready for prod LangChain to abstract LLM calls across any OpenAI-compatible endpoint Mem0 managed cloud for semantic memory — no Qdrant, no Pinecone, no infra to run Three memory scopes: per-channel, per-thread, per-DM Built-in !clear and !memory commands A clean, extensible architecture you can fork and build on Architecture Before diving into code, here's the full request lifecycle: ┌─────────────────────────────────────────────────────────────┐ │ Slack │ │ @mention in channel ──┐ │ │ DM to bot ──┼──► Slack Events API │ │ Thread reply ──┘ │ │ └───────────────────────────────────│─────────────────────────┘ │ (Socket Mode / HTTP) ▼ ┌─────────────────────────────────────────────────────────────┐ │ slack-bolt (Python) │ │ bot.py ──► router.py ──► handler.py │ │ │ │ │ ┌───────────────┤ │ │ │ │ │ │ ▼ ▼ │ │ Mem0 Client LangChain │ │ (managed) ChatOpenAI │ └────────────────────────────────────────────────────────────-┘ │ ▼ ┌───────────────────────┐ │ Mem0 Managed Cloud │ │ Vector Embeddings │ │ Entity Extraction │ │ Deduplication │ └───────────────────────┘ The ke

La dictée vocale en français québécois, c'est pas un gadget : c'est un problème de code-switching

J'utilise la dictée vocale tous les jours depuis six mois. Pas pour taper moins vite. Pour penser plus vite quand je vibe-code avec Claude Code et Cursor. Pis j'ai fini par construire mon propre outil parce que les outils existants me tapaient sur les nerfs d'une façon très précise. Le problème réel Quand tu travailles en tech au Québec, tes phrases ressemblent à ça : "OK fa que je fais un useState pour le component pis je passe le handler en props" Ça, c'est une phrase normale. Personne en tech QC ne parle autrement. Pas parce qu'on est négligents avec la langue. Parce que le vocabulaire technique vient de l'anglais et qu'on le soude naturellement au français au fil de la pensée. Ça s'appelle le code-switching. Et c'est là que la plupart des outils de dictée craquent. Ce que les outils mainstream font mal Dragon NaturallySpeaking Dragon, c'est le vieux standard. Médical, juridique, corporate. Ça coûte environ 500$ en une shot. C'est lourd à installer et à entraîner. Et sa gestion du français québécois avec des termes tech intercalés... c'est en gros zéro. "useState" devient "usé état". "Fa que" devient "faque" parfois, "fake" d'autres fois. C'est aléatoire. T'as intérêt à corriger après chaque phrase. Wispr Flow Wispr Flow est plus moderne. UX propre, cross-platform, et leur gestion du français s'est améliorée. Leur plan Pro coûte 15$/mois, soit environ 144$/an. Mais il y a un problème structurel que leur propre doc admet : la détection de langue se fait par session, pas par mot. Autrement dit : Wispr détecte la langue une fois au début de la session. Si tu commences en français, il reste en mode français jusqu'à la fin. Les mots anglais qui arrivent dans la phrase, il tente de les translittérer en français. "Handler" peut devenir "andler" ou "ender", "props" survit parfois, parfois pas. C'est variable. Pour une phrase de temps en temps avec un mot anglais, ça passe. Pour un vibe-coder québécois qui switch constamment dans la même phrase, ça ne passe pas. Pourquoi

All you need is... (r)evolution!?

This is just an opinion of what I experience and am witnessing, but looking at how LLMs scale feels like I've seen it before: with CPUs trying to outrun Moore's Law and break the rules of physics. Heat, power leakage, and diminishing returns made it increasingly expensive to squeeze out even small gains in clock speed. The GHz race shifted because it had to. For LLMs, more compute, more data, more parameters, and everything just keeps getting better? That curve seems to hit a ceiling and innovation needs to succeed the scaling race now. History does not repeat itself, but it rhymes. What learnings can we make from history to "predict" a potential future? History In the early 2000s, CPUs ran into a wall, a very physical one ^^ So makers adapted. Instead of crunching every single watt out of a single core, multi-cores became common. Athlon 64 x2, Pentium D, PS3 with its heavy Cell approach. From linear to parallel. From sequential to multi-threaded (and funny race conditions ;). Talks of distributed systems, SIMD/MIMD and new benchmarking spawned into what we have today. We still use CPUs, but differently. We still have Memory, but think about Cache, RAM, GPU or Unified. Same same, but different. Innovation because of limitation. Present I feel something similar is about to happen to gen AI. Yes, there are improvements in different areas, some in scaling, some optimisation, some performance, but the slope is becoming slippery. The last 12 months went from "Opus 4.5 is the pinnacle" to "What the hell is wrong with Claude?". The perfect (business) storm of scaling execution! But the low-hanging fruits have been eaten and the crops don't grow as fast anymore. Costs rise quickly, latency becomes a constraint, and even large context windows feel more like extensions than breakthroughs. What remains is more incremental, more expensive, and more complex. You could argue the whole venture of "agents" is the same multi-core experience repeating itself. A different kind of orch

I Replaced 12 Developer Tools with ChatGPT (Here's What Actually Happened After 30 Days)

I have a confession. Somewhere around day nine of this experiment, I almost quit and went back to my old setup. Not because ChatGPT was bad. Because I was bad at using it. I kept typing half-questions the way I'd type into Google, hitting enter, and getting answers that were technically correct and completely useless. It took me about a week to realize the problem wasn't the tool. It was twelve years of muscle memory. This post is the long version of what happened when I tried to go a full month without my usual stack of developer crutches — Google, Stack Overflow, Regex101, JSONLint, a SQL formatter site, a commit message generator, a pile of bookmarked Docker cheat sheets, and a few other tabs I didn't even realize I kept open until they were gone — and replaced all of it with a single ChatGPT window. I work as a backend-leaning full stack engineer at a small e-commerce company. Python and Django on the server, a chunk of Node for a couple of internal services, Postgres, Docker, and an AWS setup that I inherited rather than designed. Nothing exotic. Which is actually why I think this experiment is useful — most of you reading this aren't working on some bleeding-edge ML pipeline either. You're maintaining stuff, fixing stuff, shipping features under deadlines that someone in another department picked without asking you. So here's what happened. All of it. The good parts, the embarrassing parts, and the parts where I quietly reopened Stack Overflow in an incognito tab because I didn't want my browser history to judge me. TL;DR I tried to replace 12 daily developer tools with ChatGPT for 30 days straight, tracking what worked and what didn't. Google search volume dropped by roughly 70%, but it never hit zero — and I don't think it should. Stack Overflow was the hardest habit to break, and also the one I missed least once I'd broken it. The small utility sites (Regex101, JSONLint, SQL formatters) were the easiest wins. ChatGPT replaced almost all of them outright. Do
