Emphasising diversity and inclusion, ACM supports underrepresented groups through dedicated councils and events such as the Richard Tapia Celebration of Diversity in Computing. It provides educational resources, including curriculum guidelines and scholarships, and promotes ethical standards via its updated Code of Ethics. ACM's publications, such as the Communications of the ACM and the Digital Library, serve as vital repositories for research and innovation, while its advocacy in public policy and recognition of technical excellence through awards like the A.M. Turing Award underscore its commitment to advancing computing's impact on society.

Mozilla's Thunderbird email client has transitioned to using OAuth2 with PKCE as the default authentication method for Yahoo, AOL and ATT accounts, enhancing security and enabling access to calendars and contact lists. Users with a single account can log in with their email and password, granting Thunderbird access to their data, while those with multiple accounts must adjust hidden preferences to ensure compatibility.

The OAuth2 process involves verifying identity through username, password and optional confirmation steps, resulting in an access token stored by Thunderbird for future use. Users encountering issues with sign-in attempts may need to enable cookies, update authentication settings to OAuth2, or resolve account-specific restrictions imposed by providers. Additional steps include importing Yahoo contacts via an LDIF file and configuring calendar access through Yahoo's support resources. Troubleshooting typically involves verifying password validity, ensuring cookies and JavaScript are enabled and confirming correct authentication settings, with further assistance available through Mozilla's support forums.

Coding An HTML 5 Layout From Scratch

Here is an article that demonstrates how to build a functional layout using HTML5 and CSS3 despite both specifications being works in progress at the time. In doing so, the author advocates for progressive enhancement and graceful degradation techniques to ensure compatibility across browsers. Building on this foundation, the tutorial walks through creating a blog-style layout featuring semantic HTML5 elements such as header, nav, section, article, aside, figure and footer, integrated with microformats for enhanced semantic meaning. In practice, the markup eschews traditional div-heavy structures in favour of more meaningful tags, whilst the styling employs CSS3 properties like border-radius, text-shadow and advanced selectors including pseudo-classes and attribute selectors.

Microsoft offers a range of development tools tailored to different needs, with Visual Studio serving as a comprehensive integrated development environment primarily for large-scale software projects, particularly those within the .NET ecosystem, though it also supports other languages and platforms through extensions. It is designed for enterprise applications, desktop software and complex solutions, featuring advanced debugging, testing and integration with Microsoft services. In contrast, Visual Studio Code is a lightweight, cross-platform code editor with a vast extension ecosystem, suitable for a wide array of programming languages and workflows, emphasising speed and flexibility. Its web-based counterpart, often referred to as Visual Studio Code Online, provides a browser-based environment ideal for quick edits or cloud-based development but with limitations in local system access and extension availability. Each tool caters to distinct scenarios, from heavy enterprise development to agile, multi-language projects and remote collaboration, reflecting a spectrum of approaches within the software development landscape.

yEd is a free, cross-platform desktop application designed for creating and editing high-quality diagrams, supporting manual creation or data import from formats such as Excel or XML.

Available on Windows, macOS and Linux, the tool is suitable for both personal and commercial use, with a focus on usability through an intuitive interface. Based on the yFiles diagramming library, it supports a wide range of diagram types, including flowcharts, BPMN and UML and integrates with platforms like Atlassian Confluence. User testimonials highlight its effectiveness and ease of use, with many praising its value as a free tool for professional and academic purposes.

SolarWinds has issued security updates to address four critical vulnerabilities in its Serv-U file transfer software, which could allow attackers to gain root access on unpatched servers. The most severe flaw, CVE-2025-40538, involves a broken access control issue that enables the creation of system admin users and arbitrary code execution under high-privilege conditions. Additional vulnerabilities include type confusion and an insecure direct object reference flaw, though exploitation typically requires existing administrative access. While over 12,000 Serv-U servers are exposed online according to Shodan, Shadowserver estimates fewer than 1,200 are actively accessible. The software has historically been a target for cybercriminals and state-sponsored groups, with past exploits linked to ransomware campaigns and zero-day attacks. CISA currently tracks nine active SolarWinds-related security flaws, underscoring the ongoing risk posed by unpatched systems.

ModPageSpeed

ModPageSpeed 2.0 is a self-hosted web optimisation tool designed to enhance site performance without relying on external services such as proxies or CDNs. Supported by We-Amp B.V., it builds on the original mod_pagespeed project but introduces a new architecture that processes optimisations outside the main request path, reducing latency and ensuring content remains on the user’s servers. Key features include automatic image transcoding into multiple formats and resolutions, heuristic-based critical CSS extraction and sub-millisecond cache hits using a zero-copy memory-mapped system.

It supports any HTTP-based origin server and operates with minimal configuration, requiring only a licence key for activation. Unlike the older mod_pagespeed 1.x version, which is no longer actively maintained, ModPageSpeed 2.0 includes modern capabilities such as AVIF support and container integration while maintaining a conservative approach to optimisations to prevent site disruptions. The tool is available for a monthly subscription fee, with a free trial period and is positioned as a secure, GDPR-compliant alternative to cloud-based optimisation solutions.
