Here’s why it’s a good idea …. (The server was upgraded on the 23rd of May. The graph shows CPU time – where yellow is idle and blue+green are used/busy).
3D Printworld‘s new website recently went live. We wrote it from the ground up, applying a theme provided by an external designer. It has a responsive design so should look good on mobile and desktop platforms and an integrated CMS for administrators to update content through. It uses PayPal for payments. So, if you need […]
Our 9th birthday seemed to slip by quietly last month. Whoops.
Recently, the Bromsgrove Hockey club asked if they could show upcoming matches / fixtures / results on their website. Here’s a short summary of how we integrated Google Drive/Docs Spreadsheets with WordPress.
One consistent pain has always been resizing a filesystem without rebooting on Linux. Thank fully in recent years, this has changed with filesystems like BTRFS – where you can do something like the following….
xdebug – profiling a really long running PHP application (and handling really large cachegrind output files)
Normally, profiling a PHP application is pretty straight forward thanks to the great xDebug . Normally, we’re looking at profiling a slow page (taking 5-15 seconds to load) and improving it’s performance down to a sub-second response. Such profiling can produce relatively large output files – e.g. in the order of a few hundred megabytes. Unfortunately […]
Somehow we’d not come across this little “hack” before, so perhaps others haven’t…. Anyway, rather than recreating a new TCP connection to a host, SSH can multiplex the traffic down an existing connection to that host. This results in subsequent ssh connections opening quicker. The magic stuff is – * Edit ~/.ssh/config * Add in […]
A new wordpress site we’ve architect-ed has just gone live – Flashbak.com
One customer parse a substantial amount of (somewhat poorly formed) XML on a daily basis. (I say poorly formed as the prolog does not specify a character set — i.e. the file starts with <?xml version=”1.0″> and not <?xml version=”1.0″ charset=”UTF-8″> and different files will contain either UTF-8 or ISO-8859-1 text depending on the data […]
If you’re running low of memory on a server, there may be scope to free up memory through use of ‘ksm‘. (Note, that the kernel will start looking for memory to de-duplicate if KSM is turned on AND there are some processes running which have notified the kernel that they’re candidates; ‘kvm’ does the latter.)
