Docker permission denied: what the error is actually telling you A client messages me about this error almost every week. They run a command, see "permission denied", and assume Docker is broken. Docker is rarely broken. People just use one name for two completely different errors. The first happens before any container starts: your user cannot talk to the Docker daemon. The second happens inside a running container: the app cannot write a file. The fixes have nothing in common, so ...

You add a directory to Wazuh file integrity monitoring, change a file, and nothing happens. On Wazuh 4.14.7 the usual reason is the schedule, not a bug. We measured it on a manager container. The defaults The <syscheck> block in the 4.14.7 manager image's default ossec.conf : <frequency> 43200 </frequency> <scan_on_start> yes </scan_on_start> <alert_new_files> yes </alert_new_files> <directories> /etc,/usr/bin,/usr...

The previous post covered why I chose pgvector for semantic search. But there was another question: When should a memory be embedded? At first, it might seem simple: Create memory ▼ Generate embedding ▼ Save embedding But this makes memory creation dependent on the embedding process. If the embedding provider is slow or unavailable, creating a memory could also fail or become slow. I wanted to separate these two operations. The architecture became:...

LopeBase: The Meta-Tool for Managing the Side Project Graveyard Why It Matters Most developers experience a specific type of burnout known as "dashboard fatigue." You have a SaaS product, a personal blog, and maybe a utility library, and you’re expected to monitor uptime, manage deployments, and curate content across three different interfaces that don’t speak to each other. LopeBase, shared on Hacker News, attempts to solve this by acting as a unified orchestrator for these dis...

Better graphics do not automatically create a new way to play. The question I care about is whether AI can change what happens between the player and the game. Gaming spent decades improving the surface. More polygons, bigger maps, faster networks, and production budgets large enough to fund a small country. The actual relationship between player and game barely moved. We still press buttons while software follows rules written months ago. AI agents finally have a chance to change th...

Understanding the DSPM Findings Landscape Data Security Posture Management (DSPM) tools generate a deluge of findings, each representing a potential vulnerability in an organization’s data security infrastructure. Analogous to cracks in a dam, these findings vary in severity—from minor misconfigurations to critical exposures. Without a structured approach, the sheer volume of alerts overwhelms security teams, leading to inefficiencies and heightened risk of catastrophic breaches. The challen...

I built a Palworld breeding calculator, but the part I most want other developers to use is the data. The dataset behind the site is now public as JSON and CSV: https://www.palworldonline.net/data Disclosure: I built and maintain the calculator I am linking to here. It is free to use, does not require an account, and is not affiliated with Pocketpair or Garena. This post is about what is in the dataset, why I opened it, and the breeding-data bugs it is designed to prevent. ...

canonical_url: https://arielchangdev.github.io/angelina-finance-agent/ Building a hybrid local+cloud AI system under two hard rules — $0 cost and never break production. The interesting part wasn't the happy path; it was the 9 production bugs and what each taught me about where reliability actually lives. A war-stories write-up. The system was fun to design. The interesting part was the nine ways it quietly broke — and what each one taught me about where reliability actually lives. ...

I kept catching myself doomscrolling, so I built something to replace it: CurioQuest , a free web game where curiosity earns you XP. 👉 Try it: https://curio-quest-phi.vercel.app/ What it does 🏛️ Forgotten Wonders: stories about obscure history and nature mysteries (the Antikythera Mechanism, the Dancing Plague of 1518, Göbekli Tepe), each with a 3-question quiz 🔬 Science Fact Lab: rapid true/false facts with sourced explanations and accuracy streak multipliers 🧩...

When I checked my AI usage dashboard, two numbers made me stop: 145 million tokens. 8,377 requests. I don’t code. Vijay, our founder and main developer at 123sudo, handles that side of the work. These were my conversations. In September, I wrote about those figures on Medium. My 9xchat dashboard showed an all-time cost of about $637 . That wasn’t my complete AI spending for the year. Including other AI tools and services, I estimated I was approaching ₹1 lakh . Those ar...

Palworld breeding looks simple when you are just putting two Pals into the farm. From a code point of view, it is a nice little data-modeling trap. I built and maintain a free Palworld Breeding Calculator for Palworld 1.0. It lets players pick two parents and see the egg, pick a target and find valid parents, plan multi-generation breeding trees, and inspect the data behind the tool. Disclosure: this is my project, and the link above goes to it. It is free to use, does not require an ac...
