Somewhere in your monitoring right now is an alert that fires regularly and that everyone has learned to ignore. It's not telling you about a problem anymore. It's telling you about a threshold someone set once and never revisited. And every time it fires and nothing bad is happening, it trains your team to trust alerts a little less. That's the real cost of a noisy alert, and it's worse than it looks. It isn't just the annoyance of another notification. It's that alert fatigue is corrosive. ...

Some bugs announce themselves. You're reading through a codebase and the vulnerability practically waves at you from the screen. This was not one of those bugs. This one required me to ask a question that I almost didn't ask. And that question led down a rabbit hole that ended with a server-side request forgery in a fairly popular AI SDK. The Context I've been doing security reviews of AI-related tooling lately. Partly because it's obviously where the industry is heading, and ...

You can spend a fortune hardening the perimeter and still get walked through the front door by someone who simply asked nicely. The uncomfortable truth of security is that the strongest link in most organizations is the technology, and the weakest is the person reading their email at the end of a long day. Attackers know this, which is why so many real intrusions don't start with a clever exploit. They start with a message. An email that looks like it's from a colleague, a vendor, or the help...

A Japanese version of this is on Zenn . My desk has a MacBook and, permanently parked next to it, a ThinkPad running Arch Linux that I use for build chores. I was setting up a smart plug I'd just bought when it occurred to me: this random lump of firmware is on the same network as my Mac. So I decided to simulate "one cheap IoT device got popped" and see how far I could get attacking the Mac from the ThinkPad. My Mac also runs a defense app I built myself — RoamSwitch — so this doubl...

v0.2.1 RELEASED — Aug 28, 2026. Release notes · Field test report · PyPI v0.2.1 Update: The 2,333->359 join collapse described in this article is now structurally prevented. v0.2.1 adds row-count invariant assertions at all 5 pipeline seams — the pipeline fails fast if any rows are silently lost. Also new: false-negative measurement (1.7-3.4% missed-issue rate, first recall data ever reported) and 55 new unit tests. Previously: Most AI Second Opinions Are Fake Adversar...

agent-harness-defense v0.2.0: dual-lattice IFC for LLM agent privilege escalation An open, offline-verifiable admission layer that stops instruction-privilege escalation in coding agents by enforcing a plan-first information-flow policy. A research prototype with a rigorous audit — not a turnkey production defense. The problem LLM coding agents run over untrusted web pages, docs and tool output while holding authority over security-sensitive resources (deploy keys, CI ...

Before diving further into the study of crackmes, it seemed appropriate to write a short introduction to x86_64 assembly language. It is a complex architecture, mainly due to the vast number of instructions in its instruction set. Registers On the x86_64 architecture, there are 16 general-purpose 64-bit registers. Each register has a full 64-bit name and can be divided into sub-registers to manipulate 32-bit, 16-bit, or 8-bit data. The 16 General-Purpose Registers (...

Every KL University student knows the panic - semester end approaching, attendance borderline, no idea if you're going to get a hall ticket or not. The official portal shows your percentage but tells you nothing useful - not how many classes you can still miss, not whether you're in the condonation range, not how many consecutive classes you need to attend to recover. So I built a tool to fix that. What I Built The KL Attendance Calculator is a free web app for KL...

In December 2025 I wrote that Claude Opus 4.5 changed everything. I had been using AI coding tools since the beginning. They were useful, but they were also unreliable. The working pattern was defensive: stage every change, review every prompt, stay on feature branches, lean hard on CI, and be ready to roll back. Then I spent serious time with Opus 4.5. What shifted was not that the model suddenly produced perfect software. It still didn’t. What shifted was the economics of my own time. I ...

For years, "MPLS vs SD-WAN" was a genuine, close debate. In 2026 it mostly isn't, for most companies, and it's worth understanding exactly why, because the exceptions matter as much as the general rule. What MPLS actually offered, and why it made sense once. MPLS is a dedicated, private networking technology that gives you predictable, reliable, high-quality connections between your sites, essentially your own private highway rather than the shared public internet. It made complete sense wh...

Near Field Communication (NFC) used to require native iOS or Android mobile applications. With the Web NFC API , modern web apps can now read and write physical NFC tags directly in the browser—no app store downloads needed! Whether you are building digital business cards (vCards), smart event passes, Wi-Fi credentials sharing, or hardware tap-to-pay experiences, Web NFC unlocks a whole new dimension of web-to-physical interactions. In this guide, we'll cover: 📱 Browser & device sup...

An "84% of monthly budget used" email landed on a Tuesday. I read it. I forwarded it to myself with a note that said watch this . Then I let the batch job run overnight anyway, and by Thursday morning the account had burned $1,900 against a $600 cap. Nothing malfunctioned. The alerting pipeline worked exactly as specified, delivered on time, to the right person, who understood it. That's the uncomfortable part, and it's not a story about discipline. A budget warning is a scarcity...

If you searched for a klogg alternative , you probably already know klogg is good. It is fast, it is free, it is open source, and it runs on Windows, macOS and Linux. Most people who go looking for something else are not unhappy with klogg as a viewer. They are unhappy with one specific moment in their day: Opening the file again. You investigated a 48GB log yesterday. You closed it. This morning your colleague asks about a different error, and you have to wait through the whole index b...

Twenty-one bytes. That is the entire attack. A file smaller than a URL, with four zero bytes sitting at exactly the right offset, crashes any FFmpeg-based application that opens it and reads a packet. Not memory corruption, not some exotic heap trick. A division by zero, in code that has been shipping for years, in one of the most fuzzed codebases on the planet. The person who found it, Darío Clavijo, did not write the fuzzer by hand. He built it with AI assistance, the way a growing number o...

Some fortnights the complaints about AI come from people who barely use it. This one they came from the people who use it most. Scroll Hacker News over the past week — the forum where developers argue about their tools in unusual detail — and the grievances about AI coding assistants weren’t existential. Nobody was worried about the robots waking up. They were worried about their bill, their UI, and the effort of reading what the model just wrote. Quotes sourced from: Hacker News. Every quo...

디지털 자산 생태계는 혁신과 파괴의 최전선에서 전례 없는 속도로 진화하며, 기술적 선견지명과 끊이지 않는 규제 마찰이라는 두 가지 특징을 동시에 보여준다. 지난 10년간 이 역동적인 환경을 관찰해 온 연구자로서, 이 산업이 본질적인 암호화 위협부터 전통 금융 시스템 및 정부 감독과의 복잡한 상호작용에 이르기까지 다층적인 문제와 씨름하며 성숙해지고 있음이 분명하게 느껴진다. 최근의 여러 사건들은 이러한 다면적인 현실을 더욱 명확히 보여준다. 이는 미래 인프라를 보호하기 위한 선제적 조치들, 새로운 금융 상품을 정의하고 규제하려는 지속적인 노력, 그리고 디지털 자산 시장이 전 세계 거시경제적 요인에 점점 더 민감하게 반응하는 현상들을 부각한다. 리플(Ripple)이 XRP Ledger(XRPL)의 양자 내성 강화를 위해 추진하는 야심 찬 계획은 미래 지향적인 접근 방식을 잘 보여준다. 이는 가상의 것이지만 잠재적으로 치명적인 암호화 취약점에 대해 그 위협이 현실화되기 훨씬 전부터 대비하...

Your task is to substitute all occurrences of the string Text with Echo-Location within the XML file located at /root/nautilus.xml on ...

A GitHub Copilot spending limit is a monthly budget, set in billing settings, that caps metered AI credit consumption for an enterprise, an organization, a cost center, or a single user. Creating one takes about two minutes. Knowing what it stops takes longer, and the gap between those two things is where most surprise Copilot invoices live. Two facts account for nearly all of them. On enterprise, organization and cost center budgets, the setting that actually blocks usage is off by default, ...

If you are a woman in tech who is stuck in "tutorial hell," constantly taking courses but never actually deploying real software, this is for you. I am Mary Macharia, a Software Engineer specializing in Backend Development, AI/ML, and QA. I founded SHEinnov8 because I noticed a massive gap in our community: plenty of brilliant women have the drive to build something real, but they lack the space, the collaborative structure, or the network to actually push it across the finish line. We ...

There’s a funny (and slightly sad) story behind why I built mabims.dev . It started with a date. More specifically, a Hijri date . Once Upon a Time, the Government Website Had the Date For a long time, Indonesia’s Ministry of Religious Affairs (Kemenag) website displayed the current Hijri date. It was convenient. You opened the website, looked at the corner of the page, and there it was: Today: 30 Sha'ban Simple enough. A lot of people, including me, go...

An API operation can receive input from several places. Path parameters identify the record. Query parameters filter or paginate the result. Headers carry metadata or authentication. The request body contains structured data for create and update operations. An MCP tool should give the AI client one clear input schema. That is the mapping problem: HTTP API inputs path + query + headers + body become MCP tool input one structured schema the AI client can understand ...

Google Hotels already compares every booking site for a hotel and a stay — Booking.com, Expedia, Agoda, Hotels.com and the hotel's own site. It has a "track prices" button too, but it emails you on its own terms, picks the sources, and keeps the history. If you want the numbers — for a trip, a rate parity check, or a price history chart — you need them as rows. This is how to get Google Hotels prices for exact dates as JSON, without a Google API key (there is no public Google Hotels API for r...
