3 March 2019: Style Sheet Update
As technology has evolved it seems that Project Euler has taken time to catch-up. A common request in recent years has been to modify the style sheets to be make the website mobile device friendly. This includes a responsive framework that should dynamically adapt the display to accommodate a variety of screen widths.
It has taken a lot of work, given the regimented tabular structure of many pages, but we are pleased to reveal the fruits of that labour.
This has required significant changes not only to the style sheets, but the way in which the scripts dynamically produce pages. Extensive testing has been made, but as you can imagine there are going to be some setups that had not been anticipated and consequently pages may not render as expected. In addition, as part of the the process a number of decisions have been made to modernise the style sheets, including the use of CSS variables to simplify future changes. Whereas support for this has been in place in all of the main browsers for several years now, it does mean that some old browsers may suffer. Special provision has been made to provide legacy CSS support for Internet Explorer, which means that IE will only render a version of the default theme .
If you notice any specific issues, then we would ask you to report them at the following address on our alternative forum.
For many members they will notice nothing more than, what we hope, a cleaner more pleasing appearance. For mobile device users we hope that the effort was worth it and navigating the site becomes an enjoyable experience.
20 October 2018: Weekly Publication Schedule
About a year ago we decided to reduce the release of new problems to one problem every two weeks.
Thanks to the many contributions made by our members we now have enough problems in stock to release one problem every week. Because we don't want the authors to wait too long before their problem is published we make the following decision: At the start of each new batch of problems (usually 6 problems) we will make a decision to release those problems weekly if there are sufficient problems in stock; otherwise we will follow a two-weekly schedule for that batch of problems. At the top of news page you can always see when new problems are released.
We hope that members will keep contributing enough proposals to maintain a weekly publication scheme.
25 September 2018: Progress Page Change
Just in case you thought your Progress page was broken, a small and deliberate change has been made to the colour scheme on the grid showing which problems you have solved. Along with being more in-keeping with the general site colour scheme, the shading indicates the relative difficulty of the problems. Hopefully the changes aren't too distracting and will serve to provide more useful information on that page.
27 May 2018: Project Euler and the GDPR
As many of you will know, the law concerning any data held by European citizens: General Data Protection Regulation (GDPR), came into effect on 25 May 2018. Not only is the website hosted in Europe, but a large proportion of our membership also live within Europe, so this legislation affects us.
We hope that you are happy with the outcome of our review and continue to enjoy being a part of the Project Euler community.
18 February 2018: Changing Statistical Data View
It is now possible to change the statistical data shown on the Statistics pages from the default view of all registered members to active members only; that is, members who have solved a problem within the last 365 days.
