2 Oct 2017

Have you jumped on the cryptocurrency bandwagon yet? Either buying your own with fiat money, or dedicating some hardware to mine it? This article shows how you may have been contributing some computing resource to mine crypto recently without your conset. A script by a company call CoinHive has been making an appearance on various websites, using the visitors browsers to mine cryptocurrencies. End user computers are one resource for hackers to exploit, and if you’re not careful your virtual machines running in the cloud could be compromised by hackers to mine crypto.

How to slice 10% off your build size with Ionic 3.7

2 Oct 2017

While some of the Ionic team is busy working on the Web Component based version of Ionic 4, we still get to enjoy frequent releases of Ionic 3.x. Last week delivered us Ionic 3.7, which brough the version of Angular used up to 4.4.3 (from 4.1.3) which brings us the new HttpClient API, amongst other changes. The corresponding update to @ionic/app-scripts also brings us the CLI update which incorporates the new angular optimizer build tool, ngo.

Memcache cache Adapter for Parse Server on Google App Engine

24 Jul 2017

Increasing performance and reducing costs is a constant goal in cloud applications, and caching is often an effective way to make improvements. The Parse server supports a cache adapter which caches commonly queries such as database schema, users, roles and sessions. Out of the box Parse comes with a cache adapter for Redis, which is a top choice when it comes to caching. Our full stack Ionic and Parse app runs on the Google App Engine, which has a Memcached service.

How to complete promises in parallel using async and await

1 Jul 2017

Back in the bad old days of node.js the asynchronous code handling was done with callbacks, resulting in deeply nested and indented code which could quickly become difficult to follow. The advent of promises simplifed the chained asynchronus calls to a more managable linear fashion, but there was still a few gotchas for beginners, and complex conditional logic could still be tricky. The async and await keywords promise even more simplicity in handling asynchronous event, resulting in code written in a synchronous manner which makes it easer to understand and reason.

Scrum

30 Nov 2016

Software development has had a checkered history of projects running over budget, missing functionality and delivering late. A significant contributor to these failures is use of the waterfall approach to software development, where a specification is handed over to the development team at the beginning, and the first release of software delivered late in the development cycle, with user acceptance testing to follow. Agile development methodologies came about to fix the problems inherent with this approach by increasing customer engagement throughout the process and continuous delivery of working software.

Debugging a critical local storage Heisenbug

21 Sep 2016

The German theoretical physicist Werner Heisenberg first asserted the observer effect in quantum mechanics, which the act of observing a system causes its state to alter. This gave rise to the computer programming term Heisenbug for a bug which disappears or alter the program behavior when one attempts to debug it, which can be a very frustrating experience. When a customer was doing some testing before rolling launching their Cloneder based app we received an email
