CISA Warns of Cyberattacks Targeting PLCs in US Water Sector

·1 views

The US Cybersecurity and Infrastructure Security Agency (CISA) has issued an alert warning about threat actors actively targeting programmable logic controllers (PLCs) used in water sector facilities. PLCs are critical industrial control devices that manage automated processes such as water treatment and distribution. The alert highlights vulnerabilities that could allow attackers to disrupt or manipulate essential water infrastructure operations. Cybersecurity firm Censys has published analysis supporting the advisory, identifying exposed water sector devices potentially at risk. Water utilities are being urged to review their security posture and limit internet-facing exposure of industrial control systems.

Lucide, Tabler, and Phosphor: A Data-Driven Comparison of Free Icon Libraries

Lucide, Tabler Icons, and Phosphor are three widely used open-source icon libraries, each with distinct design philosophies and coverage. Lucide and Tabler both use a 24x24 stroke-based grid with 1,778 and 6,143 icons respectively, while Phosphor uses filled paths on a 256x256 grid and offers 9,161 icons across six weight variants. When measured by unique icon concepts rather than total count, Tabler leads in distinct coverage, and Phosphor's tally is inflated by its six-weight system. All three libraries are permissively licensed — Tabler and Phosphor under MIT, Lucide under the functionally similar ISC — with no attribution required for commercial use. Designers are advised to audit coverage for niche-domain needs before committing to a library, as breadth varies significantly across specialized categories.

One Developer's Account of Being Stretched Across Three Roles as AI Replaced Teammates

A software developer recently shared how their employer consolidated frontend, backend, and QA responsibilities into a single role after AI tools were introduced to fill the gap left by departing teammates. The title and pay remained unchanged, while the scope expanded dramatically across disciplines the developer had little prior experience in. Although AI proved effective at handling syntax errors and generating boilerplate quickly, it failed to provide the contextual judgment needed to evaluate whether solutions were appropriate for a specific codebase. The developer shipped two tests in their first month that passed but tested nothing meaningful, only discovering the flaw after a colleague flagged it in code review. The key takeaway was that AI closes the syntax gap almost instantly but does nothing to replace the hard-won experience required to distinguish working code from genuinely correct code.

Three Ways to Use SVG Icons in React and Next.js With Tailwind CSS

Developers working with React, Next.js, and Tailwind CSS have three main options for integrating SVG icons: inline components, SVGR file imports, or sprite references, with inline being the most common choice. Converting an SVG to a React component requires adjusting attribute casing, such as changing stroke-width to strokeWidth and class to className. In Next.js App Router, inline icon components work as React Server Components by default, rendering static markup server-side and adding nothing to the client bundle. Tailwind CSS styling is straightforward since most icon sets use currentColor, allowing size and color to be controlled via utility classes like h-*, w-*, and text-*. Accessibility best practices recommend hiding decorative icons with aria-hidden, while standalone icon-only buttons require an accessible name on the interactive element itself.
