Yii is a PHP framework that many organisations use to build medium to large web applications. Its latest generation, Yii3, reached its first stable release at the end of 2025. It is a complete rewrite as a set of separate packages built on PSR standards and…
Once a website works on every screen size, the next step is to give it character and make it a pleasure to use, with crisp icons, smooth mobile menus, scroll effects and gentle page transitions. These used to need jQuery and many plugins, but today the…
Most people switch between phones, tablets and computer screens of many sizes throughout the day, so a good website must stay easy to read and use on every screen. Responsive web design is the set of ideas and techniques that lets a single page stretch,…
The database is at the heart of an organisation's systems, so a database administrator (DBA) has to keep data available, recoverable when things go wrong, safe from unauthorised access and consistently fast. SQL Server 2025 adds features that help directly…
HTML and CSS are the foundation of every web page. HTML5 lets you build forms, add audio and video and structure pages without plug-ins such as Flash, while modern CSS brings Flexbox, Grid and media queries so sites look good on every screen size. Add…
Many organisations start keeping data in Excel because it is easy, but as the data grows and more people need it, they run into duplicates, inconsistent entries, several versions of the same file and reports that have to be compiled by hand every month.…
HTML and CSS can now do far more than lay out pages. Much of what once needed large JavaScript libraries, such as tooltips that stay attached to a button, scroll-linked animation, smooth page transitions or reusable components, is now built into the browser.…
Although many new APIs use JSON, XML is still the main data format wherever structure must be strict and verifiable: banking, insurance, government, electronic documents, Office files, SVG, sitemaps and the SOAP web services organisations still use to connect…
PostgreSQL has become the first-choice database for modern applications, from backend systems and SaaS products to workloads that keep JSON or vector data alongside relational tables. Yet many developers still treat PostgreSQL as a generic database behind an…
Social media has become the main way people in Thailand keep in touch, work, buy and sell, and follow the news every day, on Facebook, LINE, Instagram, TikTok and YouTube. That convenience comes with risks: hacked accounts, personal data leaked through…
jQuery is a JavaScript library that makes it quick to select elements, change the DOM, handle events and make Ajax calls with short code, and it is still found on a great many websites, including internal systems and WordPress and other CMS themes and…
Email and calendars are still the main way organisations work, yet many people use Outlook only to send and receive mail. Their inbox holds thousands of messages, they cannot find old email, large attachments fail to send, and meetings arranged over chat get…
Work in many departments starts in Excel, but as the data grows and more people share it, problems appear: duplicated records, inconsistent typing, links between lists that are hard to follow, and reports rebuilt by hand every month. Microsoft Access…
MySQL sits behind a great many systems, from websites and ERP platforms to internal business applications. As those systems grow, administrators need to decide which MySQL release to run, how to configure it to be fast and secure, which backups can genuinely…
Joomla is still the open source CMS behind many websites in government agencies, schools and organisations. The whole look of a site depends on its template, yet many sites still run old templates that cannot be upgraded, or have edits made directly to the…
Word is not just for one or two-page documents. Real work in organisations means annual reports, manuals, theses and large batches of circulars. Formatting them by hand means that a small change to the content throws out page numbers, the table of contents…
Short-form video, online ads, channel intros and corporate communications call for more professional-looking motion every day, in several sizes for both landscape and vertical screens. Many people start with After Effects and get stuck at stiff movement: they…
Ajax lets a web page send and receive data from the server without reloading the whole page, so it underpins instant forms, search boxes with suggestions, shopping carts and almost every back-office system. Browsers now provide the Fetch API as standard, many…
Good photographs are at the heart of PR work, product images and portraits on websites and social media, but pictures from cameras and phones often come out underexposed, with colour casts, distractions in the scene, or skin and details that need cleaning up.…
Paginated reports that print neatly to a set layout, arrive in executives' inboxes every morning and can be opened in a browser from one central place are still at the heart of reporting in many organisations that run SQL Server. In 2026, though, the platform…
Online meetings are now part of everyday work in every organisation, from team meetings and customer calls to staff training. Yet meetings still stumble because the audio is unclear, the organiser does not know how to run the room, uninvited people get in, or…
Almost every business application reads and writes a database. Many .NET developers still maintain code built on DataSets, older Entity Framework versions on .NET Framework or LINQ to SQL, which is no longer developed, while new systems use Entity Framework…
A good business application needs more than code that runs. It has to be layered so it is easy to maintain, validate its data, be testable, log enough to trace problems, stay secure and be easy to deliver to users. On today's Microsoft platform this is done…
Perl is a scripting language that excels at text processing, reading logs, converting files and writing system administration tools. It still ships with most Linux and macOS systems, and many organisations run systems written in Perl that need looking after…
