When you're working with Sass and use Gulp to compile your  .scss files it can happen that you introduce an error by accident. You misspell one of your mixins or variables and gulp-sass will throw an error. When this happens your Gulp task crashes and you have to restart it. When I started using Gulp this drove me crazy and I really wanted a solution for this problem. Gulp-plumber The solution I found is called gulp-plumber. This nifty plugin catches stream errors from other plugins and allows you to handle them with a custom handler. You can also let gulp-plumber...

When working with assets you will often want to change some of them. My personal experience is that I often want to resize images, stitch them together, blur them or convert them from .png to .jpg. When I had to do this I usually sighed, fired up Photoshop, created a batch and then ran everything in my folder through that batch. When I realized I got it wrong I would have to do this again and Photoshop usually crashed at least once in the process as well. Needless to say, I did not enjoy adjusting my assets. Until I didn't...

Let's talk about tools first Lately I've noticed that many Front-end developers get caught up in tools. Should they use Less, or Sass? Do they code in Sublime or Atom? Or should they pick up Coda 2? What frameworks should they learn? Is Angular worth their time? Or maybe they should go all out on Ember or Backbone. And then any developer will reach that point where they want to actually compile their css, concatenate their javascript and minify them all. So then there is the question, what do I use for that? Well, there's many options for that as...

This is the third post I'm writing about my swift adventure and it's been great so far. I feel like I've been able to learn a lot about Swift and UIKit. I did miss two days because I was extremely busy those days, so that's a bit of a shame. In week three I focused on learning UI stuff rather than focusing on building Arto App, I decided to do this because a better understanding of UIKit might be very important in the process of developing it. I also took a peek at CoreData which was interesting. UIScrollView I used...

Every since responsive design became a thing people worried about the sizing of their images. Why would you serve an image that's 1800px wide to a device that is only 320px wide? That's a very sensible question to ask when you're dealing with responsive design. If you consider that this 320px wide device might very well be a mobile device that's using a 3g connection this question makes even more sense. Working towards a solution I think it was a few years back when I saw people debating the problem of responsive images. How would the syntax look? How will...

Time flies, it’s been two weeks since I started my daily Swift adventure and I only missed one day. Pretty impressive I’d say. The second week of the daily Swift was a very practical one. It was all about looking through Arto App and building the components I’d need to actually build this app. Building it will be a part of the daily Swift. Layout and Constraints A big part of creating a beautiful feed of content seems to be understanding the UITableView. More specifically, understanding UITableViewCells. These Cells are the core of what a user will see and interact...

It's been my goal to learn how to build apps for a bunch of years now. I’ve picked up some books on Objective-C, tried building some things but lost interest really quick every time. The first time I actually went through with building something was when I was graduating from college. Shortly after that Swift came out and I wanted to learn it. But, once again, with no real goal except just learning Swift I quickly lost motivation to actually do something with it. But then something happened, I realized that motivation is fleeting. It’s not reliable, one day I could be super...

When writing CSS for websites it's easy to use pixels for everything. Just measure up everything in the design you were given, fill out the numbers and you're done. You've built a beautiful pixel perfect website. Until somebody comes along with a mobile phone. Or their 13" laptop. Or maybe somebody is using a fancy 27" iMac screen. The retina version I mean. Then everything looks weird. Maybe the design doesn't quite fit, causing a vertical scroll. Or maybe the design is an old fashioned 960px grid site. That would certainly create huge amounts of whitespace. Oh and then there...

A while ago I wrote about sharing cookies on an old Tumblr blog of mine. I figured it contains some valuable information so I migrated the post here. The reason I wrote it was that I was working on a pitch that would take a user through a series of puzzles. Each puzzle would enable the user to see the next website(subdomain) and I decided I'd save the progress of the user in a cookie. Normally you'd define a cookie for a domain like www.example.com. When the browser tries to read this cookie, the current domain has to be www.example.com. So sub.example.com wouldn't work and...

While working on a personal project I figured I'd use Bootstrap because then I wouldn't have to worry about styling. All was very well and using Angular.js together with Twitter Bootstrap totally made my day. But then I needed to show a modal dialog. I know how to do this but I stumbled upon the Angular UI directives for Bootstrap this seemed great. I mean, that's just awesome. Using the power of Angular's directives should get these modals up and running super fast. Or so I thought.. After skimming the docs and looking at the modal example I figured I'd give it a...
