Statistics Not Compatible With Varnish

Filed under


VARNISH is valuable for a number of reasons, including security, privacy, and performance. I first used it around 2009 when another site of mine had repeatedly come under DDOS attacks. Using Varnish means that requests for pages usually come from the same IP address (the cache proxy), if at all. Much of the time visitors get served static (cached) pages transparently and quickly. The downside is, this interferes with statistics (the Apache server does not even see all requests) and it is not compatible with modules like polls, where each IP addressed is allowed just one vote.

During the server/site migration we tried to preserve as many of the features as we could. There was a transition from old Debian to new CentOS and the new architecture is quite different (still 2 CPU cores but with more RAM, a virtual container, and resilience owing to proxies/redundancy). Thanks to those who suggested workarounds. We have looked at some of them, but without losing on performance there is no way to keep meaningful statistics. These statistics have been disabled. Not even we, with direct access to the server and the CMS, have access to meaningful statistics.

We are going to try to focus on high quality selection of news, not on numbers.

Emulator now runs x86 apps on all Raspberry Pi models

Eltech’s faster ExaGear Desktop software version now supports ARMv6, in addition to ARMv7, letting users run x86 apps on all models of the Raspberry Pi. Russia-based Eltechs announced its ExaGear Desktop virtual machine last August, enabling Linux/ARMv7 SBCs and mini-PCs to run x86 software. That meant that users of the quad-core, Cortex-A7-based Raspberry Pi 2 Model B, could use it as well, although the software was not yet optimized for it. Read more

Maintaining an open source project at the Guardian

Over the 2015 Easter holiday the Scribe project received more than 3000 stars (a combination of bookmarking, liking and favouriting) on Github, making it easily one of the most popular open-source projects we have created at the Guardian. In addition to that milestone we also celebrated the release to our internal production systems of a number of community-contributed changes to Scribe. Guardian journalists now benefit every day from participation in the open-source community! Read more
