Creating visually consistent and automatically updated figures in LaTeX can be a frustrating task - especially when external plots break your carefully crafted layout. This article presents a streamlined workflow for integrating matplotlib plots directly into LaTeX documents using the pgf backend. With just a bit of Python and a clever Makefile, you can generate publication-ready figures that match your documents fonts, scaling, and style perfectly - no more mismatched labels or manual re-exports. Whether you are preparing a thesis, research paper, or technical documentation, this guide shows you how to build an efficient and reproducible figure pipeline. It covers every step: setting up your Python scripts, writing a clean Makefile for automation and including pgf figures in LaTeX with minimal hassle. Perfect for researchers, students, and LaTeX enthusiasts aiming for professional, maintainable document workflows.

Docker is praised for its portability and reproducibility - but does it actually simplify anything for small-scale deployments? This critical article explores how containerization, often touted as a silver bullet, can introduce unnecessary complexity, obscure logs, fragment configuration, and increase operational overhead when all you're running is a handful of stable services on a single machine. From tangled networks and ephemeral volumes to questionable security defaults and brittle image updates, the article challenges the assumption that Docker is always the right tool. For sysadmins who value clarity, control, and long-term maintainability, it argues that the native power of traditional Unix tools may offer a cleaner, more transparent path - without the scaffolding.

Dive into the fascinating world of radiation detection with the Radiacode 102, a compact and capable gamma spectrometer featuring a CsI(Tl) scintillator and digital readout. Unlike traditional Geiger counters that only measure radiation intensity, the Radiacode provides detailed spectral data - allowing you to identify specific isotopes like Potassium-40 or Cesium-137. This article introduces the physical principles behind the device, compares it to Geiger detectors, and demonstrates how it brings professional grade analysis to hobbyists, educators, and field researchers alike. Whether mapping environmental radiation via smartphone and GPS, performing lab-style fixed source analysis, or automating data collection using Python and USB, the Radiacode 102 shines in both mobile and programmable applications. Explore its real-world capabilities, app integration quirks, FreeBSD USB configuration tips, and learn how to visualize your own spectra - complete with logarithmic plots and isotope fingerprints. A must-read for citizen scientists, educators, and anyone curious about what quietly glows in our world.

If youโve ever glanced at a statistics report or scientific article, youโve likely seen both terms - often side by side, and often misunderstood. This short post untangles the difference, giving you the tools to know whether you're talking about how spread out your data is, or how precise your mean estimate really is. Whether you're brushing up for data analysis or just curious, this post offers a short explanation of these two core concepts - and why confusing them can mislead your interpretation. A perfect refresher for students, researchers, and curious minds alike.

This article walks through a simple, dependency-light approach to convert Jupyter notebooks into static HTML pages using Python and a shell script. With inlined images, clean output, and zero JavaScript bloat, the method is perfect for solo researchers who want long-term accessible documentation without setting up full-blown platforms like JupyterBook or mkdocs. The presented mini-solution shows how to automate conversion, resize and embed photos, build a simple index and deploy notebook archives effortlessly. Whether one is documenting experiments, maintaining an engineering diary, or just prefering timeless, static web output - this mini guide offers a robust and minimalistic solution that stands the test of time and costs near zero effort.

The internet was born as a place of open exchange - a decentralized space where information could flow freely between humans and machines alike. But in recent years, this vision has faded behind paywalls, anti-bot defenses, and corporate silos. This article revisits the foundational principles of the web - from the stateless beauty of HTTP to the semantic depth of HTML - and defends the right of machines, scripts, and individuals to explore, remix, and reuse knowledge. Whether it's an AI compiling a knowledge graph or a hobbyist scraping environmental data for new insights, the web thrives on reuse - not restriction. But as politics and profit increasingly gate what was once open by design, we risk silencing not just users, but entire ecosystems of digital creativity. This piece is a call to remember: the web was made to be read by anyone - including machines.

Once upon a time, building software meant writing code, compiling it, and running it - on any platform, with minimal fuss. In this sharply opinionated piece, a veteran developer reflects on the simplicity and elegance of past development practices, where tools were lean, dependencies rare, and source code reigned supreme. Todayโs software world, by contrast, is tangled in dependency hell, plagued by fragile build systems, bloated binary blobs, and unnecessary complexity. With passion and precision, this article challenges the modern obsession with packaging and platform-specific toolchains, calling instead for a return to sane, portable, long-lived software practices. A must-read for anyone who's ever sighed while waiting for npm install to finish.

Cement is the invisible backbone of modern construction - yet few understand the intricate journey from raw rock to the fine grey powder that holds our buildings together. This article offers a detailed look behind the scenes of cement production, from blasting limestone in quarries to the high-temperature chemistry inside rotary kilns. Each step, from raw material grinding to the final packaging stage, is part of a precisely orchestrated industrial process balancing mechanical engineering, thermodynamics, and chemical transformation. Whether you're curious about the role of gypsum, the formation of clinker phases like alite and belite, or how modern plants reduce emissions through calciners and dust filters, this overview connects the dots with clarity and technical depth.

This article explores the technical foundations, financial implications, and ethical questions surrounding tracking cookies on modern websites. From how they work and why they exist, to the real difference they make in supporting free content, you'll gain a clear picture of the trade-offs involved. Whether you're a privacy conscious user, a curious web reader, or a content creator wondering how others fund their work, this short article explains why your cookie choices matter - and how they shape the future of a free and open web.

While promising transparency and control, most CMPs are embedded from third-party domains, in theory allowing silent collection of metadata across sites in the same way as the very trackers they claim to regulate. The irony: users are asked to trust a system that itself introduces new risks, all without meaningful technical guarantees. This article dissects how CMPs, especially certified ones, operate within an ecosystem that relies on trust instead of technical safeguards - a flawed model in a world where trust alone is no protection. We explore how true privacy must be built on browser-level enforcement and origin isolation, not legal promises or banner overlays. If we want real control over our data, itโs time to move beyond privacy theater.
