Semantic tags Semantic tags describes is meaning in human readable language. Looking at the tag we can tell what tag it is. for example: <header - represents top header content. <nav> - holds the navigation link. <footer> - holds bottom footer/copyright information.
LinkedIn has no bold, italic, or strikethrough button. Yet you constantly see posts with fake bold headers and slanted emphasis. Ever wondered how that actually works? It's not formatting, it's a different alphabet Unicode has a block called Mathematical Alphanumeric Symbols (U+1D400 to
An agent proposes refund_order. The tool exists, its arguments are valid JSON, and the model sounds confident. None of that answers the question that matters: is this action allowed now? Google's Agent Development Kit gives us interception points before and after agents, models, and tools. The temp
Power BI is Microsoft's tool for turning raw data , an Excel file, a database, into interactive dashboards and reports, without needing to write much code. You connect a data source, clean it up, build relationships between tables, and then drag fields onto charts that anyone can click through an
I remember my very first encounter with a Python error. I was so excited! I'd just written a tiny script – maybe it printed "Hello, World!" or a simple variable. I saved it, opened my terminal, typed python my_script.py, and BAM! A wall of red text assaulted my screen. File "my_script.py", line 3
Day one I built the agent loop. Day two, the session record. Day three I ran ./run-ticket.sh US-04 and nothing happened: no error, no output, no ticket executed. The loop had been running for two days, and that early morning, for the first time, there was no way to see it. A script that sa
Hi Codez, Today I'm taking my first step toward building my own chatbot. Now, the obvious assumption is that you need a GPU like an NVIDIA CUDA-compatible card, plus a subscription to a high-level LLM like OpenAI's or Claude's models. But here's the thing — as learners, we don't need any of that.
I have recently started to learn python, and coming from Java there are a few interesting things I have found about functions. The first thing that stuck out to me is that in Python, functions are values. What I mean by that, is a function is a thing that you can store, just like you can store a nu
The specification here is append-only. You never edit a row. To change one you retire the old row, which stays in the file under a retired heading, and stand a new row beside it. The old text remains readable, so a reader six months later can see what the rule used to say and why it moved. Two tool
A Bitcoin price chart shows the path prices took. For this report, I wanted to estimate how the volatility of daily returns changed along that path. I used a Markov-switching model and built the visual report in OWL Compose. The report includes state probabilities, a transition matrix and a compari
Ask any club that has put a camera on a court what happened next, and you will hear a version of the same story. The camera works. The footage exists. And then a member asks for "the video from Tuesday", and somebody spends twenty minutes scrubbing through a day of continuous recording, exports a cl
I build TagKing.io on my own: a two player game of tag that runs in a browser tab. One player is "it", touching the other passes it on, and whoever is "it" when thirty seconds run out loses. There is a ranked ladder, so it has to work online between strangers. This week I finally got a friend on a
Version 3.8 of the Toolbox App restores keyboard navigation in project and tool lists. On macOS, manual IDE updates stay available even when the system reports the installation directory as protected. IDE updates remain available on macOS macOS was sometimes incorrectly reporting an IDE installation
I run an automated system on a remote machine with nobody watching it. When I started, I described it to people as passive. Over two days it needed five separate interventions. None of them were exotic, and that's the point of this post. The gap between "automated" and "passive" is made of very ord
The rapid expansion of artificial intelligence applications is driving a significant surge in demand for network speed and capacity. Industry stakeholders are now finalizing the 1.6 terabit Ethernet standard to address these growing bandwidth requirements. This shift represents a major leap in data
A long working day produced three lessons. Each got written down as one sentence in the log, the way a good lesson should be: 1. Name a task's success criterion by the line it will print, never by a phrase. 2. Regenerate the derived index before mirroring the tree, not after. 3. A bulk removal ru
I'm Ramiro Quintana, a Software Engineer & Full Stack Developer. I built Calculadora SIU CrediUPE to solve a small but repetitive problem I encountered while using SIU Guaraní at Universidad Provincial de Ezeiza (UPE). When checking my study plan, I wanted an easier way to keep track of how man
I kept seeing early teams put off the founders' agreement until there was already a fight. Lawyers are expensive when equity is still fluid. Templates are a wall of legalese. Most tools want an account. So I built FounderAgreement.com. What it does Guided questions on equity, roles, ve
A request arrives at your server for /api/vehicles/1' OR '1'='1. Before a single line of your application code runs, something in front of it reads that string, recognises the shape of a SQL injection attempt, and answers 403. That something is a web application firewall, and last month I spent a w
Learn how to handle unexpected empty objects ({}) in API responses cleanly in Angular before they break Date pipes or ruin your UI tables. When building enterprise applications like CashBooks or Accounting Ledgers, you often deal with large JSON objects containing optional properties. A common iss
