SARS-CoV-2 and COVID-19

Throughout the current coronavirus pandemic, LPA is continuing to work as normal, to develop its software and support its customers. All directors and employees are working from home, and using online meetings to communicate with colleagues. Our usual phone number (+44 8871 2016) and email addresses (...@lpa.co.uk) continue to work as normal. We hope and wish that all our customers stay safe and well.


Introducing Weblog!

Weblog is the fresh, new toolkit which provides a direct, streamlined way of combining beautifully designed web pages with logical scripts written in Prolog.

Weblog separates the processes of website design and content programming, so that web pages can be created in familiar tools such as DreamWeaver, PhotoShop and Illustrator, independently of the application code which supports them.


Thawte Secured Website

LPA has acquired SSL Certification from Thawte, and this entire website is now secured by TSL (notice the padlock icon in your browser URL window). Our web-deployment technology, Weblog (see above) works perfectly though our TLS-encrypted gateway, without any changes to the code.
