Using Streams with Fetch for Efficient Data Processing

Using Streams with Fetch for Efficient Data Processing IntroductionJavaScript has evolved significantly since its inception, particularly with the expansion of web technologies that demand efficient data processing. One of the core developments in this regard is the introduction of Streams—a programming construct that allows the handling of data in a continuous flow. Combining Streams with the Fetch API revolutionizes how developers manage and process large amounts of data, optimizing

Show HN: Detect LLM hallucinations via geometric drift (0.9 AUC, 1% overhead)

I built SIB-ENGINE, a real-time hallucination detection systemthat monitors LLM internal structure rather than output content.KEY RESULTS (Gemma-2B, N=1000):• 54% hallucination detection with 7% false positive rate• <1% computational overhead (runs on RTX 3050 with 4GB VRAM)• ROC-AUC: 0.8995WHY IT'S DIFFERENT:Traditional methods analyze the output text semantically.SIB-ENGINE monitors "geometric drift" in hidden states during generation - identifying the structural collap

Ask HN: Are AI "Chatbot Wrappers" ruining EdTech? I'm testing a proactive UX

Hey everyone,I’ve been doing customer discovery with CS students learning Data Structures and Algorithms. Right now, every AI tutor in the market is just a reactive chatbox (like ChatGPT next to a code editor).The problem is, when a student is completely stuck on a logic problem (like Dynamic Programming), they don't even know what to prompt the AI. They just stare at the screen.I am validating a new UX: A Proactive AI Mentor without a chatbox.Instead of the user prompting the AI, the AI si

Show HN: BaitAI – Conversational AI interviews with realtime interview artifacts

We’ve been building BaitAI, a conversational AI interviewer for interview practice and async candidate screening.AI interviews can feel like filling out a questionnaire - you answer a static question and get generic feedback. Real interviews are conversational: interviewers ask follow-ups and adapt based on what you say.BaitAI runs interview-style sessions where the AI asks questions follows up based on your responses probes your reasoning and evaluates how you communicate your approach and give

Show HN: A 100% free, universal ATS resume builder (no export paywalls)

Hi HN,I noticed a terrible trend in the career tools space: "free" resume builders that let you spend an hour typing out your work history, only to hide the final PDF export behind a $15/month subscription.I built MakeMyCVFree as a genuinely free alternative. It is an ATS-friendly resume builder that generates clean, single-column templates proven to pass Applicant Tracking Systems.Alongside the free CV maker, I built an ATS resume scanner that mimics recruiter bot logic to give y

I built a governance layer for multi-agent AI coding – lessons after 6 months

Six months ago I started coordinating multiple AI coding agents (Claude Code, Codex CLI, Gemini CLI) across parallel terminals for a production project. The agents were productive, but I had no idea what they were actually deciding or why.The problem wasn't capability — it was accountability. An agent would make a choice buried in a 50-file commit, and I'd only find out weeks later when something broke. No trace of which agent did what, when, or based on what context.So I built a gover

Inheritance: a web component super power

By now, you have realized that I basically only post discussions or implementations that have come up on the job. This one is no different. I want to walk you through an implementation that we did recently and highlight a super power of web components that can be very useful when used correctly.I‘ll use a few examples that show exactly how I use inheritance to my benefit when building systems of components, and I‘ll also give a word of caution, because great power also comes with great responsib

Generating 21 Multilingual Promo Videos from React Code with Remotion

I run Amida-san, an online Amidakuji (lottery ladder) service. For the Product Hunt launch, I needed a 30-second demo video, a 15-second clip for X, and a calmer pitch version -- each in English, Japanese, Chinese, and Korean.You can see the actual videos on the Amida-san top page.A promo video embedded on the landing page, showing the Amidakuji animation scene.Doing this manually in a video editor was not realistic. Instead, I wrote everything as React components. Remotion converts JSX to MP4 -

What’s the Best DevOps Platform for Startups?

For startups, the ability to move fast while maintaining stability is critical. You need to release new features quickly, but downtime or deployment errors can be costly. Choosing the right DevOps platform is key to achieving this balance.There isn’t a single “best” DevOps platform for every startup. The ideal choice depends on your team size, product architecture, cloud provider, and growth plans. This guide explains what to look for, common options, and how to make the right choice. What

Bringing Microsoft SAM Back to Life: How SAPI4 TTS Works in the Browser

Do You Remember That Voice?If you grew up with Windows 2000 or XP, you probably remember Microsoft SAM — the robotic, slightly eerie text-to-speech voice that could say anything you typed. It was the default voice of the Microsoft Speech API 4.0 (SAPI4), and for an entire generation, it was the first encounter with speech synthesis.Kids would type absurd sentences into the Narrator tool just to hear SAM butcher them in the most entertaining way possible. And then there was BonziBUDDY — tha

Week 1 of JavaScript: The &quot;Minestrone&quot; Stage

The "It's Not That Bad" PhaseI just finished my first week of JavaScript. Going in, I was prepared for a nightmare of complex syntax and confusing brackets. To my surprise, the foundations felt... accessible? Variables? Just boxes for stuff.Loops? Just doing the same thing until you're tired.Functions? Just a recipe you save for later.I spent the first three days thinking, "I’ve got this. I’ll be building the next Netflix by Sunday." The "Minestrone" Problem 🍲Then came Day 5. This is

Ask HN: Did your client ever replace you by a more junior freelancer?

I got a client for 3 years and out of the blue they picked a more junior freelancer and did not renew my contract. The problem is that my code and architecure were really good there, so much so that adding new functionality was extremelly easy (due to the well architected code). The client most likely wanted a confirmation that my job could be done cheaper, and the easy to maintain and extend code I wrote made him think so. So I was dropped. In the end I was out of a gig for doing really excelle

Show HN: Ctxt.sh – Ask questions about any codebase, get answers with citations

I&#x27;m 19, a solo developer and freelancer. I built ctxt.sh because I was tired of spending weeks understanding new codebases when joining projects or inheriting legacy code.ctxt.sh indexes your entire repo – every file, every commit, every PR discussion. Then you can ask it questions in plain English:&gt; &quot;How does authentication work?&quot;&gt; &quot;Where is the Stripe webhook?&quot;&gt; &quot;Why was this API changed last month?&quot;It returns answers with citations – links to spec

Unpaid – AI payment reminders that verify, escalate, and auto-reply

I built a tool because I was tired of writing this email: &quot;Hi, just following up on my invoice from 3 weeks ago...&quot; I ran a small business from 2016 to 2019 and lost it because clients didn&#x27;t pay on time. The stress of constantly following up, not knowing what to write without sounding rude, feeling like you&#x27;re begging to be paid — it eventually broke the business. I sold at a loss and went back to full-time employment. Years later, with an IT background going
