Linux: better fonts for Retina display

24 February 2014 in Debian, Hi-Tech, Linux, Mac

Big resolution with small screens is more and more common and we’re facing a problem on fonts visualization as the readability is not optimal. We have a lot of non adapted fonts for retina display, even if most of them are not so bad. The solution to resolve that problem is to install additional fonts to replace the default one. And one of the best one I’ve seen is Infinality fonts !

PageSpeed disable Varnish by default ! Get both working together

20 February 2014 in Debian, Hi-Tech, Linux, Web

Yesterday a colleague (Dimitri) tested a tool on this blog. He informed me that Varnish was disabled and PageSpeed may be the cause as this is the last modification I’ve made on the server. After verification he was totally right ! By default, PageSpeed disable cache by serving HTML files with: Cache-Control: no-cache, max-age=0 After reading the PageSpeed documentation on that topic, it is clear: PageSpeed needs to know how to purge the cache as it rewrites a lot of elements and it has the control instead of the application.

Deimos.fr is now using PageSpeed :-)…feedbacks

16 February 2014 in Debian, Hi-Tech, Linux, Web

Following a previous post, I’ve enabled PageSpeed on both wiki and blog deimos.fr. What I can say is, it’s very important to take the time to test every optimizations you want to add. I experienced for example issues on silly things like : # Optimize browser rendering pagespeed EnableFilters lazyload_images; Some images weren’t shown if you didn’t refresh once again your page browser. I only had this problem on the blog and not the wiki.

Page Speed: optimize on the fly your rendered code with Nginx

12 February 2014 in Debian, Hi-Tech, Linux, Web

I’ve first heard of Page Speed last year for Apache. I was really waiting a stable version for Nginx and it’s now done. A few days ago, Nicolargo made a post regarding it and that’s what motivated me to go ahead on Page Speed. PageSpeed speeds up your site and reduces page load time. This open-source webserver module automatically applies web performance best practices to pages and associated assets (CSS, JavaScript, images) without requiring that you modify your existing content or workflow.

Offloading SSL with Nginx and Varnish

23 January 2014 in Debian, Hi-Tech, Linux, Web

Varnish is a real powerful cache solution for web servers. He is unfortunately not able to do it over SSL. Anyway, there is a solution by offloading it with Nginx. Here is a schema to get a better understanding : Nginx decrypt SSL, pass it in clear to Varnish. If Varnish got it, replies to Nginx which crypt back data to send to user. I’ve made a full documentation to get it working well, follow the link.
