A Little About Printing Techniques

A printing process or system corresponds to a mechanical way of reproducing a given graphic representation on a physical medium, repeatedly and continuously. Printing systems are varied and are distinguished by direct and indirect processes, as well as by the molds of their respective matrices. Direct and indirect processes refer to how the matrix contacts the substrate – whether directly or through an intermediate element. The molds of the matrices refer to the technique by which they are formed – whether by high relief (typography and flexography), low relief (rotogravure and pad printing), flat (lithography, offset and collotype) or permeographic (screen printing).

HTTP Security Headers are a type of instruction sent by a server to guide a browser on how to handle the content of a given website securely – acting as a fundamental layer of defense against client-side attacks. They are very simple and lightweight to implement, and therefore highly recommended. These headers can also be called HTTP response headers, browser security directives, or website security enhancement headers. mplementing security headers is one of the essential security measures listed in any guide on the subject, in the context of self-hosted websites, and it does not apply to fully managed hosting environments (like WordPress.com).

Portuguese Tiles and the Legacy of Time

Leave a Comment / Gallery, Art / D Almeida

Portuguese tiles (azulejos) originate from ceramic decoration developed in Egypt and brought to the Iberian Peninsula by the Arabs during the 13th century. The word azulejo itself comes from the Arabic term al-zulaich, meaning “small polished stone.” Initially, this “polished stone” referred to small fragments broken from a larger piece, with irregular shapes. Once introduced in Spain and Portugal, this practice evolved significantly, becoming simplified, standardized, and adapted to Western styles. The first Portuguese tile workshops date back to the early 16th century, based on the Moorish technique and later developing into the faience technique, which was derived from Italian majolica.

Open‑source video applications form a vibrant ecosystem where creativity, collaboration, and transparency come together to empower creators of all kinds. These tools – ranging from editors like Kdenlive and OpenShot to media players such as VLC – give users the freedom to customize features, inspect the underlying code, and contribute improvements back to the community. Because they’re developed in the open, they often evolve quickly, shaped by real user needs rather than commercial constraints. The result is a diverse set of powerful, accessible video tools that support everything from casual home editing to professional‑grade production, all without locking users into proprietary ecosystems.
