Raspberry Pi Server

LAMP server up and running on my Pi.

LAMP server up and running on my Pi.

So this summer I’ll set up a Raspberry Pi webserver on my LAN. Since I have a fixed IP-address at home the RP should be able to work as my webserver. In due time that is. I bought the RPi with a very small SD card. All too soon it ran out of memory. I bought a 16 GB SD card and tried to install an os.

My first try was Raspian, since Debian is among my favorite distros. But the thing simply would not boot. Like at all. After several burnings, formats, gparteds and unetbootins I went for the nobrainer Noops.

After a format I copyed the files to the SD card. And … Abrahadabra … the Pi booted.

Nice.

Trends Future of Web Design

Rapid prototyping and responsive webdesign are the major trends at Future of Web Design, London 2015. Pixelperfect designs in Photoshop are sooo dead. Design in the browser is the new kid in town.

Workshops

The workshops are interesting because they give you:

  • Contact with the business.
  • Excellent speakers.

Content strategies

I attended Steve Fisher’s workshop on content strategies, and learned a lot. During the first part of the workshop Steve Fisher introduced his workflow. Then we had to try it out in groups.

With the responsive web new content strategies are needed. Several speakers focussed on the topic. ??? of the Guardian told about the redesign of the paper.

It was a story about failing, analysing and hard work before they found a formula. Perhaps not a silver bullet. But it works for the time being.

The design workflow

Of course designing in the browser will affect the workflow of the designer. In stead of painting his vision in Photoshop, the designer must work with code.

And the designer must test the production on several devices. Since there are litterally thousands of resolutions and screen sizes knowledge of libraries is important.

Perhaps code is not the first thing that comes to a designer’s mind. But as the designer from Envision said:

“It is not harder to learn code than to learn to use the graphical interface of Photoshop.”

At an early stage the designer will be able to test the production on real devices with the real target audience and the costumers.

More than one speaker stressed on working with real content in order to get the tone and voice of the product.

Of course Photoshop is not entirely dead. You still need a tool for image manipulation.

Code

Den Odell gave a very fine introduction to the future standards of HTML and CSS.

Christiano Betta introduced several libraries and validationg methods for credit card forms.

Even though most developers work with some kind of rapid prototyping framework they did not talk much about their rapid prototyping frameworks. They were mostly mentioned en passant. I’d have loved to hear more about this subjects.

Pen & Paper

The focus was clearly on content strategy, wireframing by pen & paper. Most developers talked about rapid prototyping directly in the browser.

There are many advantages when you design in the browser. You see the result immediately. If something must change, you don’t have to redraw the layout in some three to four resolutions in Photoshop. And recode your markup or stylesheet. The new workflow seems to look somewhat like this:

  • Mock up a static prototype in HTML / CSS.
  • Share your prototype with real content your prototype with the team, audience and customers.
  • Improve and iterate.

Rapid Prototyping from a designer’s point of view

Rapid Prototyping

A rapid prototype is build at the very beginning of a project. Gone and over are the days of pixel perfect wireframes in Photoshop, stated Billy Kiely

Now the entire design process is done via the browser. There are many advantages for the designer here. All design is an iterative process.

Design is all about designing interaction and storytelling.

Focus

The designer works with the interactive experience. Redesign must be easy – and with a keen focus on the story.

Three stages

There are three stages or aspects of design:

  • Aestetics.
  • Interaction experience.
  • Storytelling.

Wireframes are fine tools for the storytelling. But viewing drafts in Photoshop is not the same thing as watching your work on the actual devices.

Discover the story

If you design page by page, you risk loosing the general picture of the whole story. Therefore it’s better to work on little pieces at a time, and fill in the gabs when you see them.

Investment is the enemy of design.

Prototyping

A sum up of Billy Kiely’s rapid prototyping workflow from the designer’s perspective:

  1. Use it while you design it. You design an experience.
  2. Start with a cupcake. Get all the ingredients ready. Then you mix them in the proper order.
  3. The quicker you get feedback the better.
  4. Define the jobs to be done.
  5. Use real content.
  6. Make it accessible for the team and the costumer.
  7. Avoid the edge cases in the early stages of the work.

The Future of HTML and CSS

Den Odell on the future of HTML and CSS.

Den Odell, Sweeden,  on the future of HTML and CSS.

What is the future perspectives for the HTML and CSS standards? At the Future of the Web conference Den Odell started with a definition for responsive web design, somewhat like this:

… the website appears to have been built for that particular device.

Odell talked about what is going to happen with HTML and CSS soon, in the future and the end goal of RWD.

Soon

The new specifications for HTML5.1 and CSS level 4 is in the near future. A great improvement is the pictures tag. Here a new attribute is srcset that will work in the img and picture tags.

<picture 
    srcset="tiny.jpg 1x, larger.jpg 2x"
    src="myPicture.jpg"
    alt="Here is my picture" />

In the CSS you will be able to use the images according to media queries. And so you can have responsive images in a more elegant way.

But Odell states, that this is in the near future. By now some 52% of the web browsers support using pictures and images like that.

The future

Here Odell presented ideas for media queries, for instance a webpage might look different from country to country or even from continent to continent. The CSS might look somewhat like this:

@media {
    continent: europe;
}

Perhaps the user acitity could be monitored. What if you’re jogging while on the webpage?

@media {
    activity: jog;
}

Connection speed is also an important factor, so perhaps you could address the problem thus:

@media {
    connection-speed: slow;
}
The end goal

For Odell the end goal is this: the browsers must disappear. So in conclusion Odell asumes, that the GUI will:

… apear to have been built for the user.

From the helicopter perspective Odell’s vision is a movement from a focus on devices to focus on the user.

Data Visualisation

Lisa Gringl – Visualize Data

In this speak at the Future of Web Design, London 2015, we were introduced to basic concepts of data visualisation.

Don't use 3d in data visualisation!

Don’t use 3d in data visualisation!

How to display data

The first picture we saw were some faces. The faces were connected to a database about crime statistics in the USA. The data were connected to facial parts, such as the forehead, the eyes, the mouth etc. The higher the number the bigger was the facial part.

A face with a very big forehead might indicate a high murder rate. The look of the face would tell an interestiong story about crimes the states in the USA.

How to display data

  1. Use visual cues.
  2. Use coordinate system, cake diagrams and similar.
  3. Use a scale with x and y axis.
  4. Use colors og graphical forms to signify something, e.g. male or female.

Always check your data

Here the fun began. Lisa Gringl informed us, that a pie chart always shoul ad up to 100%. The blunder samples were just amazing.

Then she said: “Never use 3d”. We saw some horrible examples of 3d visualisations. Again the blunders were funny and useless.

Wind in the USA

As an example of a well designed animation with data visualisation Lisa Gringl introduced winds in the USA. You could follow the weather all over the USA. The visualisation is quite impressive.

The toolbox

In conclusion Lisa Gringl mentioned some of the tools of the data visualizier. Pen and paper are still going strong. So is Illustrator and even spreadsheets. The visualisations should ideally:

  • Tell a story.
  • Either serious or funny-
  • Watching the visualisation must be a benefit for the audience.
  • They must target the audience.
  • Make sure that the audience will understand the visualisation.

Apart from pen and paper Lisa Gringl recommended the

Here I would have loved to se a code sample from real life. In fact that was the only thing I missed in this talk: an introduction to the code behind an interactive data visualisation.

On Twitter Lisa Gringl recommended to have a look at the d3.js. Here you find a JavaScript library for data visualisation, and the code behind the creative work:

Steve Fisher and Content Strategy

Content Strategies

 

The finished wireframe with priorities.

The finished wireframe with priorities.

At the Future of Web Design, London 2015, content strategist Steve Fisher presented his model for content design.

At the Future of Web Design, London 2015, content strategist Steve Fisher presented his model for content design. Fisher introduced a two step model. But first he introduced four question for every website:

  1. What do you do?
  2. What is painfull?
  3. What do you love?
  4. What do you wish?

His content design principles are:

Work for a real audience

  • Users first.
  • Sustainability (that the site should be easy to maintain).
  • Accessibility for users on all devices.
  • Design for real people, not personas.

Fisher wants to work for a real audience. That’s perhaps why he does’nt like personas. He prefers to have a real audience and to talk to real persons. Developers can asume many things, when they work with personas. Only interviews with the real audience will say whether these assumptions are correct or not.

The design funnel should look like this:

  • The audience.
  • A UX vision.
  • Design principles.
  • Goals.

First of all you have to prioritize the content. Some issues may be urgent important or non-urgent important. Others may be “urgent non-important” or even “non-urgent non-important”.

Then all you must define central content. Everything on the website must be prioritized. Hay recommends to sketch out all pieces of content in order to discover the core message of the website.

Whether the screen is small or large you have to figure the patterns.

Prioritize

One way to prioritize is to create a spreadsheet and then prioritize. You need some sort of content inventory – and stick it notes can be great tools for the job. Here you have to look for patterns.

When the lists are done, they should be prioritized by importance e.g.:

  1. The standard content view.
  2. Landing pages.
  3. Product view.
  4. Application view.
  5. The homepage.

That a homepage may come in as the 5th priority may come as a surprise. But of course it depends on the website. You have to prioritize by importance, because the users may come to the landing page before the homepage.

View priorities

Another way to prioritize is to work with the views. Here you write a list with all your views, and then prioritize like this:

  • One: essential. The website will not work without these views.
  • Two: great to haves.
  • Three: nice to haves (if these views were not present, the website would work anyway. Like: social sharing).
  • Four: useless (get rid of them).

That was the starting point of the workshop. In groups we had to find a case. In our group we used an online casino as our case.

We looked at the different views, and worked in two steps. First we put the views in the categories one, two, three and four. After that we had to prioritise the ones, the twos and so forth.

Propose a new design

Having sorted the information on the website we created two essential wireframes. One for mobile devices and another for larger devices.

Responsive test tools

After the group presentations Steve Fisher gave some valuable tips for websites for responsive testing:

The Future

Steve Fishers workshop was a fine introduction to content strategy. In the group we worked with a real life case about an international web casino. In the end the workshop gave some fine inputs, tools and tips about structuring content.
