Post body Posted about ToolHub here a bit ago (free tools that run entirely in the browser - image, PDF, dev tools, etc.) and got a comment that stuck with me: the "no upload" angle is real, but I should lean into it hard for anything work-related specifically - contracts, financial data, anything someone would actually worry about touching a random server, not just present it as a generic privacy bullet point. That's a sharper, more specific pitch than what was actually on the site, so I ...

If you've shipped an LLM agent to production, you know the failure mode: a customer says the bot gave a wrong answer, you open your logs, and you see a wall of spans that tell you what happened but not why. The prompt changed three deploys ago. The agent skipped a tool call. A retrieval step pulled a stale document. Nothing in a flat trace tells you the causal chain that led to the bad output. ZizkaDB is an open-source operational database built specifically for this problem. Instead of stori...

Introduction Over the past two weeks, I have been learning the basics of Git and GitHub and how they are used in Data science. During the classes, I learned that Git and GitHub are not the same thing. Git moves files to GitHub, while GitHub is an online platform where I can store and manage Git repositories and collaborate with other developers. One of the most useful things I learned was how to take a project that is stored in a local folder on my computer and connect it to GitHub. I also ...

Introduction: The Shift from Swift to Go – A Developer’s Awakening For years, developers like the one quoted above have grappled with the mechanical inefficiencies of Swift’s compilation process. The user’s frustration isn’t just anecdotal—it’s rooted in Swift’s multi-pass compiler architecture , which performs extensive type-checking and whole-module optimizations . These processes, while enhancing runtime performance, introduce thermal and resource bottlenecks during compilation. T...

As Kubernetes continues to dominate container orchestration, understanding how its scheduler works becomes crucial for any DevOps engineer.This hands-on lab demonstrates the inner workings of Kubernetes scheduling and walks through creating a custom scheduler from scratch. Understanding the Kubernetes Scheduler Before diving into the terminal, it's important to understand the component at play. The Kube-Scheduler serves as the brain behind pod placement in Kubernetes. It follows a three-ph...

Introduction: The Fragility of Underfunded IT Infrastructure in Critical Sectors Consider the following scenario: a VPN server, located 250 kilometers away, fails to come online after a routine restart and patch application. For a healthcare organization operating within the constraints of underfunded IT infrastructure, this event precipitated a full-blown crisis. The server’s downtime severed remote access, rendering critical systems inaccessible and forcing staff into reactive, inefficient...

A shopping agent that always returns a complete answer is not necessarily useful. In commerce, completeness can be a warning sign. Product pages are uneven. A listing may state price, stock, return terms, handling time and a delivery estimate while omitting exact dimensions, compatibility, maximum load or included accessories. A human buyer usually notices the gap and asks a follow-up question. A language model may instead complete the pattern from similar products and present the inferred va...

Introduction Data is captured in almost every aspects of our lives and it is recorded somewhere. It is important to analyse this data and transform the same to useful information which will be used for decision making. For this reason, I have realized it is important to have the right knowledge and tools to transform data into useful information and also present the same in a manner decision makers can understand. This article will explain step by step my first git hub project by creating ...

Educational & Ethical Use Only — This article is provided for educational and ethical cybersecurity research purposes only. The techniques described should only be used on systems you own or have explicit permission to test. The Model Context Protocol has become the default way AI applications connect to tools and data — and, in most deployments, the least-audited trust boundary in the stack. This guide maps MCP's real attack surface and gives a practical hardening checklist for every la...

When I first started learning Git, commands such as git add , git commit , and git push seemed like separate steps that were easy to confuse. After practicing the Git workflow, I understood that each command moves changes to a different stage. The complete workflow is: Working Directory → Staging Area → Local Repository → Remote Repository In this article, I will explain each stage using a simple website project. What Is Git? Git is a version control system...

The first time you see a Git workflow, it can look like a list of commands you are supposed to memorize: git add. git commit -m "Initial commit" git push Three commands, and somehow the project ends up on GitHub. But what actually happens between creating a folder on your computer and seeing that project in a GitHub repository? The commands become much easier to understand when you stop treating them as a sequence to memorize and start seeing them as different stages...

Over three months, my static website generated 166K Google clicks from 1.39M impressions , with an 11.9% CTR and 7.5 average position . The graph also shows traffic declining after its peak. That is important: AI did not create automatic, permanent growth. What helped was using AI inside a measurable SEO workflow—and reverting ideas when the data disagreed. Here is the loop I now use. 1. Use Keyword Planner for discovery, not decisions I start with broad product terms i...

Hey fellow developers! 👋 We all need disposable email addresses for testing signup flows, verifying OTPs, or keeping our personal inboxes clean from newsletter spam. However, most existing temp mail websites are bloated with ads, slow, and lack developer-friendly features like custom aliases or easy API access. So, I built TTMAIL — a lightweight, privacy-first, serverless temporary disposable email platform built on modern web technologies. ⚡ Live Demo & Source ...

in the last piece i did autograd, and the whole point of it was that you call loss.backward() once and pytorch fills in every gradient for you, and a couple of people basically said the same thing back to me, ok that is nice but on a real network with more than one layer what is it actually doing in there. so this time i want to do the thing you will genuinely never do inside a training loop, i want to take a two-layer network and compute every gradient by hand, one node at a time, and then ty...

File Creation and Working directory *From your local device, locate and open git to access git bash *From the git bash command execution area, enter the command cd to take you to the home path. *Then enter command cd Desktop to navigate to the desktop folder. * Use the commands below to create a new folder * * mkdir my-first-project . This opens a new folder. There are two options in naming: *use hyphens to separate the name not spaces *write the folder name under qu...

I was writing a blog post about the architecture of a system I built when I found a bug in it. This is that bug, and the much more interesting thing standing behind it. The system ingests mobile mapping surveys — LiDAR trajectories with spherical photos along them, driven along roads. The files arrive in whatever coordinate system the surveyor was working in, which in this part of the world is not a settled question. So the upload form asks the user to pick one: SOURCE_SRID_CHOICES ...

This marked the beginning on an exiting journy .I started exploring Data Engineering. My firt focus was tool getting familiar with the required tools.I started setting up and exploring Dev.t,DBEaver,Aiven,git hub and git bash,Visual sudio. One of the most exiting part is that i even successfully uploaded my first project on git hub I also spent sometime learning how o connect DBeaver with databases and how to connecting them Aiven to create smooth workflow. It was challanging at times,esp...

The Scenario An EC2 instance with an attached IAM role has s3:GetObject on a bucket containing sensitive data. An attacker compromises the instance, extracts temporary credentials from the metadata service, and begins bulk-downloading objects. GuardDuty fires Exfiltration:S3/AnomalousBehavior . The development team needs 4 hours to patch. You need to cut off access now. This post walks through exactly how to do that — commands, policies, validation steps, and the reasoning behind each ...
