Fresh inputs from Confoo Vancouver 2016

I was invited to present at Confoo in Vancouver, Canada. I gave my talk “HTTP caching with Varnish” and a Symfony introduction. After having been invited to Confoo Montreal early this year, it was great to see how Confoo got an even broader range of technologies and languages covered. Many talks where on concepts first, rather than specific languages: HTTP, in-application caching, databases and so on. Other talks actively invited to learn new languages, like “Python for non-Python developers”.

Swift Alps Conference – experimentation and collaboration

The Swift Alps Conference has a special format focused on experimentation and collaboration. This is my report of the conference and the workshop Kilian and I held. The slides are available below.

Last month my colleague Kilian and I were pleased to attend the Swift Alps Conference, an experimental conference about Swift taking place in the Swiss Alps. This conference had a different format from what one can expect from a typical software development conference. In this case the format was more focused in experimenting and collaborating with other attendees with the goal of learning something new.

Why bother with User Testing? Part 2 : Answer 5 common objections

User Testing is essential, just like I explained it in my last blog post. But your client / boss refuses to pay for this option. No, sorry, this is not an option. At all. They will argue that there is no money , that there is no time left, that the product is super simple, they already know the users…

1. Why bother with user testing? We perform well!

Client: no need for this, our product is great, we’re not leaders for nothing.

Designer: Oh really? If you never test it with users, how can you be sure that they don’t struggle regularly on your product?

Accessibility: make your website barrier-free with a11ym!

Accessibility is not only about people with disabilities but also about making your website accessible to search engines robots. This blog post shares our experience with making the website of a famous luxury watchmaker more accessible, an important e-commerce application. We have built a custom tool, called The A11y Machine to help us crawl and test each URL against accessibility and HTML conformances. Less than 100 hours were required to fix a thousand of strict errors.

Issues with unaccessible application

Accessibility is not just a matter of helping people with disabilities. Of course, it is very important that an application can be used by everyone. But, have you ever considered that robots are visitors with numerous disabilities? What kind of robots you may ask, well: Search engine robots for instance, like Google, Bing, DuckDuckGo, Baidu… They are totally blind, they don’t have a mouse, they don’t have a keyboard, they must understand your content only with the source code.

Whilst it is easy to consider a man or a woman with a pushchair having a bad time in public transport, someone color-blind, a widespread disability, could also have issues browsing the web.

User Testing Part 1/2 : Why you should perform them – The risks you avoid

If the team working on a project is competent, why should it be bothered with user testing? Because user testing does not mean that anyone is not competent enough. User testing is about avoiding risks and improving a product.

Great teams sometimes deliver wrong products

Yes, why?  We perform WELL, we are talented designers, Product owners, Product designers, we know our business, we are good enough so that we don’t design unusable stuff… Therefore, our clients can rely on us for delivering simple, intuitive and cutting the edge experiences through great products…

However, there are terrible websites online. There are terrible products on the shelves, there are garments that just don’t fit what they are supposed to, there are tools supposed to simplify our lives, but they are just bringing more complexity to our lives.

Easy Storyboard translation in Xcode with Swift3

In this post I explain how we created a modular library. Today we are happy to release and open source this lib. You can find the code on GitHub. Our objective was to have one set of translation files that could be used in the storyboard and Swift.

In our multilingual iOS projects, we always struggled to translate storyboards in Xcode. We checked all around CocoaPods, but couldn’t find any efficient solution so far. Every time, we ended up with multiple versions of the storyboard along with multiple versions of ‘Localizable.strings’. It was hard to keep everything under control, specially when translations needed to be updated throughout all files.

IPC: International PHP Conference 2016 in Munich

I have been invited to Munich to do two talks at the IPC. I gave my introduction to HTTP caching with Varnish and a talk on practical tools to build REST APIs. The IPC wanted some talks in German, so the slides are in german. You can find older versions of the slides in english for HTTP caching and REST APIs. I always enjoy presenting on a topic I care about, and the discussions after the talk. I am glad to help people, and more often than not, questions lead to me having to reflect why I have that opinion or outright learning something new. The organization of the conference has been flawless and the venue in the center of Munich was very convenient.

I could not stay for very long unfortunately, but managed to sit in to a few talks. Most notable was the talk on content strategy by Neos CMS core developer Robert Lemke with a lot of valuable information. I found the slides of his talk. The other talk I managed to see was by Michael Haeuslmann on dependencies in large projects. Michael is the developer of dephpend (pronounced “defend”), a tool to analyse dependencies of your PHP code and detecting architecture violations. He advocate such tools to identify the most important places to start improving a large code base.

Drupal SearchAPI and result grouping

In this blog post I will present how, in a recent e-Commerce project built on top of Drupal7 (the former version of the Drupal CMS), we make Drupal7, SearchAPI and Commerce play together to efficiently retrieve grouped results from Solr in SearchAPI, with no indexed data duplication.

We used the SearchAPI and the FacetAPI modules to build a search index for products, so far so good: available products and product-variations can be searched and filtered also by using a set of pre-defined facets. In a subsequent request, a new need arose from our project owner: provide a list of products where the results should include, in addition to the product details, a picture of one of the available product variations, while keep the ability to apply facets on products for the listing. Furthermore, the product variation picture displayed in the list must also match the filter applied by the user: this with the aim of not confusing users, and to provide a better user experience.

One of the great things about developing an open source language is that everybody can see the evolution of the language and inspect the code. In the official release notes there is a list of all the changes that have been implemented in the new Swift version.

Web Summercamp in Croatia – PHP track

David Buchmann introducing HTTPlug

HTTP client workshop in the PHP track of Web Summer Camp Rovinj

I was invited to do a workshop at Web Summer Camp in Rovinj (yes, last year it was called PHP Summer Camp – it got bigger this year). This year, I did a workshop on building HTTP clients in PHP. I did the workshop together with Márk Sági-Kazár, the lead author of HTTPlug, the HTTP client abstraction on top of PSR-7. We used PSR-7 and HTTPlug to build a client against an example API to manage TODO items. Then we showed how to do a Symfony integration for such a client, and how the HttplugBundle can be used to debug requests that are done in Symfony. The slides are online on slides.com – though note that this was a hands-on workshop, important parts of the workshop are not visible on these slides. The workshop was well received and I hope to teach it again in the future.

Web Summer Camp is unique in being a conference that only consists of 3 hour hands-on workshops and no only talks – aside from a lightning talks session. There are workshops in the morning and in the afternoon, so during the 3 days, you get to do 6 in depth-workshops. This year, there was the PHP track with 2 parallel workshops, and an eZ publish track as well as a UX / agile track. The Summer Camp is a community organized event with a great atmosphere, nice evening activities – and keeping the prices impressively low for what you get. The included boat trip on saturday is another unique and awesome thing. In short, you should strongly consider visiting the Summer Camp next year!
