First there came pair programming, a development disciple that promised team collaboration, improved quality, inbuilt mentoring and redundancy. Now the development community is taking it to the next level - mob programming. Mob programming, or mobbing, is where the entire team works together on a single problem, sharing one PC, one keyboard and one mouse.
Read ArticleHere’s a little promises quirk that I’ve overlooked for a while. Generally we all write promises like this:
doSomething()
.then(doSomethingElse)
.then(doSomethingFurther)
.catch(handleError);
And we know that any exception raised will skip to the catch handler. Except for the initial doSomething() call. If an exception is raised here it will be treated like a normal exception and stop executing all the rest of your code. So how do you deal with it?

I’d be happier to write the HTML myself if it wasn’t such a maintenance pain keeping consistency across all the pages. I hated having to update WordPress continually to ensure my site is secure. In order to keep all my site source in Git I have to synchronise the changes that happen automatically on the server, like updates and uploads / media files back to my working copy to commit them. And it doesn’t enable me to keep any of my content in Git, which is most important, I have to take regular database backups for this.
Read ArticleI’ve recently become addicted to pallet wood projects on Pinterest, there’s something beautiful in breathing life back into old wood, and best of all it’s free. After finding a free source of pallets I’ve tried my hand a couple of projects, some shelves for the bathroom and a pallet wood stool, I was pretty happy with the results so I thought I’d try my hand at something more substantial, a coffee table.
Read ArticleCompared to other browsers, IE’s JavaScript console is pretty lacking in it’s ability to log objects, they just appear as [Object object]. As a work around for this below is a shim that will JSON.stringify any objects that are passed as parameters to console.log (or it’s sister functions like error, warn…).
Read ArticleIf your JS function needs to return a Promise but doesn’t do any asynchronous activity, you may be tempted to use the static Promise.resolve() function rather than instantiating a new Promise object. Be aware that doing this will change the way javascript errors are dealt with.
