Building Docker images on EC2 instances rather than on a local machine makes a lot of sense. You get the benefits of a consistent build environment, as well as a typically much-faster network connection than you often enjoy locally. However, there are some gotchas, and we look at these

AMP: Making the web great again Since launching in October 2015, Google's Accelerated Mobile Pages (AMP) has quickly been building up momentum, with many of the major news publishers now on board. AMP is an approach for making content-based websites fast to load, typically less than a

Good practice and scalability In this post we're going to demonstrate running Docker containers using Amazon's Elastic Beanstalk. When I was figuring out to use Docker containers on Amazon's Elastic Beanstalk, I seemed to find plenty of articles detailing how to manually setup Elastic

These are notes about how we setup Dokku on EC2 with Vagrant, Docker and Dokku. Note: an earlier version of this post mentioned that the maintainers of Dokku worked at Deis, however that's incorrect — previously Deis sponsored the project, but this has now finished, and none of the

As the number of servers under our control grows, we want to be able to improve our control over package upgrades. The problems here are two-fold: * we want to know which packages are ready to be installed * we want to have these packages already downloaded so we can install

One of the greatest things about using Node.js is the huge number of modules that you can pull down and use in your project — more than 120,000 according to modulecounts.com. This often makes it trivial to create a Node application — for example, you can create a web

Using ES6 modules today With the arrival of the latest version of JavaScript, ECMAScript version 6, we have access to some very useful features, such as the ability to properly modularise our JavaScript. Being able to use JavaScript modules is important, as it means that we can build applications (both

Although it's improved in recent times, one of the painful aspects of web development can be testing that your site works well on mobile devices. This particularly applies when you're developing on your local laptop with wireless network connection, and want to view the site on

Many devices these days support local storage, meaning that we can store assets in local storage on the first visit by the user to a given URL, and then on subsequent visits choose to retrieve assets from local storage rather than downloading them again. Steve Souders has done a quick

Foundation 5 is a great CSS framework, providing lots of useful functionality that makes building modern websites easier. However, Foundation 5 doesn't provide support for IE8, although we can make up for this with a few polyfills and some well-placed conditional comments. Internet Explorer 8 lives on

When deploying applications into production, the challenge then becomes keeping on top of any errors that may be thrown during day-to-day operation. In the bad old days, you might put in some error trapping to log to a disk file (and then remember to check this file regularly)

One of the painful points of doing PHP development is the time that one has to wait for the PHP scripts to render the page, especially when using CMSes and frameworks which involve a lot of server-side PHP processing. Of course, PHP can be cached as bytecode, though in

We've been busy recently, and have made some changes which will allow you as a publisher with meBooks to more easily monitor your sales via meBooks and affiliates. Access your sales history Previously, after the end of each month, we've sent you a statement showing your

A question from one of the publishers that we work with got me thinking about eBook pricing, and I realised that the conversation about pricing seems to have become a bit quieter that it was a year or so ago. I'm sure pricing is constantly at the forefront

After a long gestation, we're happy to announce that the Gisborne Photo News is now available online. This includes all 257 issues from June 1954 through to November 1975, and comprises some 18,058 pages. Along with the Nelson Photo News, digitised previously and also available online, there

Note: I've made some changes to this post as a result of the build mechanism for epubcheck-3.0-RC-1 moving to using Apache Maven. More details can be found in our current repository on github. If, like me, you do a lot of EPUB creation, you

Recently I've been stumbling across many markdown documents, a format similar to the simple markup languages found on most Wikis that has become more popular at least in part because of github's use of markdown for creating documentation. The goal of the Markdown syntax (according to
