Your trace shows api-gateway calling orders, then stops. orders definitely called inventory, but inventory appears as a separate, parentless trace. The context did not propagate. It happens at four specific boundaries, and each needs a different fix. Boundary 1: protocol translation W3C Trace Context travels as a traceparent HTTP header. gRPC has metadata, not headers, and the mapping is not automatic unless an instrumented interceptor does it. from __future__ i...

Understanding VPCs, subnets, route tables, Internet Gateway, NAT Gateway, Security Groups, NACLs, IAM, and S3 through one real-world request. What actually happens when a user opens an application running on AWS? You have probably seen diagrams like this: User → Load Balancer → EC2 → RDS It looks simple. But then the questions start: How does the request enter the AWS network? Why is the Load Balancer in a public subnet? Why is the application serve...

Have you ever converted a PDF invoice, financial summary, or multi-column table into Microsoft Word, only to discover that editing a single number ruins the entire layout? Text overlaps. Columns shift unexpectedly. And when you try to insert a new line, you find that words are trapped inside individual floating boxes rather than sitting inside an actual table. Here is a straightforward, non-technical look at why this happens and three quick tests you can use to tell if your converted docum...

Subsea fiber-optic cables carry roughly 95% of intercontinental data traffic, making them critical infrastructure for finance, cloud computing, military communications, scientific research, and ordinary internet use. Satellites attract more public attention, but they do not carry the bulk of global communications. A single modern fiber pair can transmit data at terabits per second. A transoceanic cable may contain 12, 16, or 24 fiber pairs, with total design capacity measured in hundreds ...

A guardrail that only knows categories can label a problem. It can't reason about one. The bouncer who never read the guest list Most guardrail tools look the same: categories (content safety, PII, prompt injection), a detector for each, and a threshold. Cross it and you're blocked. That's a taxonomy . It answers "which bucket does this belong in?" You need one, but a lot of teams (me included, a while back) treat the buckets as the whole safety system. An ontology a...

I was checking out Hacktoberfest Weekend Challenge submissions. I do this from time to time on DEV Challenges, even when I myself don't have time to submit my own projects. This time was no different. I didn't have time to submit my own project, but had a couple of hours to checkout other submissions. Then I was wondering, what would be my project if I had time! 🤔 Before I go forward, I just want to spit something out! Yeah, I could just ask Claude, Antigravity, or GitHub Co-pilot t...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built I built RootCause for my friend, Ojju. Ojju is learning how to code and kept getting stuck on logic problems. Every time he asked AI tools for help, they would just hand him the entire correct code. It solved the problem, but it ruined his learning process because it didn't teach him how to think. RootCause is an AI learning companion that strictly refuses to give you the answer....

The client goes quiet. Glances off to the side of the screen. Types into the chat: "sorry, is that a bot recording?" The next twenty minutes of the call go differently. More careful. Flatter. This isn't about ethics. It's about the fact that a conversation changes when there's a visible witness in it. Ten AI assistants that never join the call — including CatchMeet, which we built. Forty real meetings. Eight weeks. Below: how it works, what survived, where it breaks, and what happens with ...

Around three months ago, I successfully compromised Hercules, an Insane-rated Windows Active Directory machine on Hack The Box. Hercules was an interesting challenge because it required chaining multiple Active Directory weaknesses rather than relying on a single misconfiguration. The attack path required understanding how seemingly limited permissions could be chained together to obtain increasingly powerful access within the domain. Full Kill Chain: LDAP Injection → LFI → ASP.NET C...

StudyForge AI: A Gemma-Powered Student Workspace Built for a Friend Students don't usually have a shortage of things to do. They have too many. Classes, assignments, notes, coding practice, exams, internship applications, deadlines, and personal goals all compete for the same limited amount of time. The difficult question isn't always "How do I study?" Sometimes it's simply: "What should I do next?" For the Hacktoberfest Weekend Challenge, I built StudyForge AI — ...

I built SearchLink, a small tool that checks a web page for SEO problems. A few weeks ago I ran it on my own 21 sites as a QA pass. All 21 answered with 200 OK, but the checker itself had three bugs. 1. Korean pages were marked "not enough text". It counted words by splitting on spaces. Korean, Chinese and Japanese don't work like that, so a full Korean page looked almost empty. Fix: for CJK text, count every 2 characters as one word. 2. Title and description limits were English only. ...

What CVE-2026-84411 says about trusting perimeter assumptions on network devices The assumption under test Network devices are often treated as part of the perimeter rather than as assets inside it. The reasoning is that a device which enforces filtering is itself protected by that filtering. CVE-2026-84411 puts that reasoning under pressure. The flaw is in the RouterOS web management service, it runs before the login check, and CISA's advisory ICSA-26-272-06 rates it 9.8 Critic...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built I built DeepCompass for my friend and study partner Nitish , as well as our fellow peers enrolled in the IIT Madras BS Degree in Data Science & Applications ,a rigorous degree program with thousands of students balancing demanding collegiate coursework, full-time jobs, and intense exam pressure. The Problem My Friend Faced In the IITM BS program, semester gr...

Most freelancers think VAT registration is something that happens to them — a letter from HMRC when turnover crosses £90,000 in a rolling 12 months. But you can register voluntarily at any point, and for some freelancers it is one of the smartest financial moves they make. For others, it is a costly mistake. Here is how to tell which camp you are in. The compulsory trigger is simple: cross £90,000 of VAT-taxable turnover in any rolling 12-month period (the threshold since April 2024) and you ...

The Claude Max plan price is $100 per month for Max 5x and $200 per month for Max 20x, both billed monthly only ( Anthropic Help Center ). Max 5x wins for most buyers: the two tiers are feature-identical, so the extra $100 buys nothing but headroom. Max 20x only pays off if you hit Pro-level limits every working day — and two separate Max 5x seats cost the same as one Max 20x, often the better split for two users. TL;DR Max 5x: $100/month. Max 20x: $200/month. Both figures f...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend . What I Built I built Pocket Tutor , a study buddy for a friend who wanted studying to feel more visual and interactive. You can start with a topic—even if you don’t have notes ready—or paste in your notes. Pocket Tutor uses them to create a short theory lesson, flashcards, and a four-question quiz. It also offers links to find videos and other study resources. The feedback guiding the next...

Hi DEV community! I'm Anish Rane , a mechanical engineer from India who moved into machine learning. I recently finished an MSc in Machine Learning & AI at Liverpool John Moores University. I started writing because most ML tutorials either drown you in maths or skip the why . I write the guides I wish I'd had when I switched from engineering to AI: plain English, worked examples, and code you can actually run. What you'll find here 🧠 Machine Learning Basics: linear ...

This is part 2. Part 1 shows how to turn a vibe-coded MVP into something an AI agent can keep extending. Here is where UECA-React came from. A project in trouble In 2022 my company was rewriting a legacy web app: .NET Core on the server, React with Blueprint.js and MobX on the client. We are a small team. No dedicated designer, no business analyst. I was on other projects and watched from the side. After a year of work, the code looked like a pile of low-level React with pr...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built My parents are actually pretty good at keeping important documents. Electricity bills, warranties, receipts, notices, insurance papers — they usually have them somewhere. The problem isn't losing the documents. It's remembering what each document means and what needs to happen next . A bill arrives and it needs to be paid before a certain date. A warranty is kept safely, but...

After deploying my Laravel application to an Ubuntu VPS using Nginx, I encountered this error when uploading a PDF: 413 Request Entity Too Large The application was running normally, but every upload request failed instantly. The Cause The issue wasn't related to Laravel. By default, Nginx limits the maximum size of the request body. When an uploaded file exceeds that limit, Nginx rejects the request before it reaches your Laravel application. The Fix Open ...

Every AI writing tool seemed to ask me to do something slightly ridiculous: Write half an email. Stop. Copy it. Open an AI tab. Paste it. Ask it to fix the sentence. Copy the answer. Go back. Paste it. Continue writing. All of that because I wanted to fix a typo or make one sentence sound less awkward. So I built DraftKey. 👉 https://www.getdraftkey.com/ The idea is pretty simple: AI writing help should feel more like spellcheck and less like visitin...

Künstliche Intelligenz (KI) verspricht vor allem eines: Zeitersparnis. Dokumente können innerhalb weniger Minuten analysiert, Softwarecode schneller erstellt und Informationen in einer Geschwindigkeit verarbeitet werden, die noch vor wenigen Jahren kaum vorstellbar war. Theoretisch sollte KI den Arbeitstag daher verkürzen. Wenn Mitarbeiter dieselben Aufgaben effizienter erledigen können, müssten sie weniger Zeit benötigen, um die gleichen Ergebnisse zu erzielen. Die Realität sieht jedoch ...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend . What I Built I built RoomTidy for my roommate: a small Windows desktop application that offers a gentle reminder when visible clutter remains in an area they choose. The user selects a fixed-camera area, explicitly saves a tidy reference, and sets preferences such as allowing books while asking for dishes to be removed. RoomTidy compares later pictures with that reference locally. It describes...
