2Replacing the BT Infinity SmartHub with pfsense

Published by & filed under Web Technologies. Last updated .

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.

0WordPress Local Gravatar cache

Posted by & filed under Wordpress.

I like to have avatars shown for people who com­ment on my blog. Word­Press sup­ports the gravatar ser­vice nat­ively so enabling this is very easy. How­ever it comes with a cost — access­ing extern­al files from anoth­er domain adds lots of extra load time in the form of new DNS look­ups, new SSL con­nec­tions to make, etc. Would­n’t it be nice to have gravatars stored loc­ally and served from your own serv­er. Well that’s what I’ve been doing for some time now, if you’d like to know how, read on…

0VPS Tweaks to improve web performance

Published by & filed under Web Technologies. Last updated .

Whilst I haven’t writ­ten many new art­icles recently I have spent con­sid­er­able time updat­ing and revis­ing the behind-the-scenes side of things, namely vari­ous secur­ity (TLS) set­tings on my VPS that hosts sev­er­al sites includ­ing this one.  Anoth­er thing I have also worked to enhance recently is to improve my use of gzip, and a new format called brotli

0Google Photo Sync limits

Published by & filed under Storage. Last updated .

Google have released a new tool to replace drive sync and pho­tos backup.  The new app, called Backup and Sync provides the func­tion­al­ity of both in a single app.  It is also claimed that it will sync folders as albums for pho­tos, some­thing the pre­vi­ous backup app did not do.  A couple of lim­its remain however.

0Localisation of Amazon Affiliates links

Posted by & filed under Wordpress.

I occa­sion­ally ref­er­ence products on my vari­ous web­sites, and usu­ally link them to Amazon for any­one inter­ested in buy­ing them. A long time ago I used to link with an amazon affil­i­ates link but nev­er earned any­thing from it as my typ­ic­al read­er­ship is well dis­trib­uted around the world. Unfor­tu­nately Amazon don’t provide a way to redir­ect vis­it­ors to their loc­al amazon site whilst retain­ing to affil­i­ates pay­ments. There are vari­ous solu­tions out there but all the ones I found had issues with them, so I developed my own.… Read Full Article

0Enable access to the c$ share on Windows 7 and newer

Posted by & filed under Windows.

I have a range of HTPCs run­ning win­dows around the house, which I largely admin­is­ter via remote desktop. Occa­sion­ally it is use­ful to access the root of the C drive remotely. Win­dows has always catered for this by cre­at­ing some default admin­is­trat­ive shares, which are hid­den. The C drive is accessed via \\remote-pc\c$ for example. In win­dows 7 I found I was­n’t able to access these shares by default as they have been restric­ted (under­stand­ably). I needed a way to make them access­ible again.

1Fixed: Media Center PC wakes in wrong resolution

Posted by & filed under Windows.

Since I upgraded my HTPC to an AMD A5400 series (from the old E350) I have had a prob­lem where on wake from sleep the res­ol­u­tion would be set wrong (1024×768 I think) instead of the full 1920×1080 that the TV sup­ports. Exit­ing media cen­ter would trig­ger a res­ol­u­tion cor­rec­tion and then media cen­ter could be reloaded without issue. This was not sat­is­fact­ory as a solution.
