0HTML5 LogoResponsive background images for websites

I’ve recently been updat­ing my web­sites and web serv­er and adding a new site (LoveCrete.org). I wanted to have a back­ground image on LoveCrete and real­ised that of course 1 size does­n’t fit all screens. Here is a sum­mary of what my think­ing was and what I did to cater for the numer­ous screen sizes and ori­ent­a­tions.

0nginx curves error SSL_CTX_set1_curves_list

I recently ran into an error with a new nginx con­fig that I could­n’t find any­where on google! Turns out that was because I was read­ing the font wrongly and sub­stitued a lower case L for a num­ber 1. So if you ended up on this psage because you searched for SSL_CTX_setl_curves_list then try search­ing again, for SSL_CTX_set1_curves_list.

0Optimising WAN MTU for BT Infinity

Since switch­ing from my BT SmartHub to a pfsense router I’ve had a few minor teeth­ing prob­lems.

0BT Mesh WiFi

After repla­cing my BT SmartHub with a pfsense router, I’ve been look­ing to upgrade the house WiFi as well. Most devices are wired as most rooms have wired con­nec­tions I fit­ted for my par­ents years ago when wire­less was barely a real­ity. How­ever phones, tab­lets, e‑readers, and laptops really do work best with wire­less (or only with wire­less in some cases), and to work well need a wire­less sys­tem that enables mobil­ity.

0Replacing the BT Infinity SmartHub with pfsense

When I moved into a new home a year ago I was finally able to join the 21st cen­tury and ordered BT Infin­ity which is sup­plied with a SmartHub. The SmartHub is actu­ally reas­on­ably decent kit con­sid­er­ing it comes for free, but as with most ISP sup­plied devices it is locked down in some ways, for example you can­’t use your own DNS serv­ers which I prefer to do. In the early days of ADSL (circa 2001) I ran a smooth­wall box in place of a router, and for a range of reas­ons (includ­ing inter­net fil­ter­ing con­trolled by me, rather than an ISP) I decided to go back to a linux-based fire­wall router.
