Principle of Least Power

Slide 14

Slide 14 text

Tim Bernes-Lee Computer Science spent the last forty years making languages which were as powerful as possible. Nowadays we have to appreciate the reasons for picking not the most powerful solution but the least powerful. e less powerful the language, the more you can do with the data stored in that language.

HTML is forwards compatible. It has healthy fallbacks for things it doesn’t know yet.

As a result of many such excellent design principles…

BrowserStack claims to have 300+ browser versions.

Slide 31

Slide 31 text

In 2011 there were 20+ mobile browsers.

Slide 32

Slide 32 text

How long can we continue doing things that way?

Slide 33

Slide 33 text

Looks are deceiving.

Slide 34

Slide 34 text

Because the web is tolerant, you can make any code “look” good on your preferred web browser.

Slide 35

Slide 35 text

Are we catering to just web browsers?

Slide 36

Slide 36 text

A whole bunch of services consume our websites — read-it-later, accessibility tools, search bots…

No one’s excluded.

Slide 49

Slide 49 text

Christian Heilmann I am always amazed about the lack of support for progressive enhancement on the web. Whenever you mention it, you face a lot of “yeah, but…” and you feel having to defend something that should be ingrained in the DNA of anyone who works on the web.

Slide 50

Slide 50 text

:/ We know our customers.

Slide 51

Slide 51 text

:/ No one uses that browser.

Slide 52

Slide 52 text

:/ We build enterprise apps.

Slide 53

Slide 53 text

:/ But that’s too much work.

Slide 54

Slide 54 text

:/ Move fast, break things.

Slide 55

Slide 55 text

:/ We make “web apps”

Slide 56

Slide 56 text

:/ Who has Javascript disabled anyways?

Slide 57

Slide 57 text

:/ Relying on Javascript is not a problem for us. Today no one can complete an online transaction without Javascript anyways.” “

Slide 58

@andyhume Progressive enhancement is more about dealing with technology failing than technology not being supported. And you can quote me on that.

Slide 63

Slide 63 text

@GnrlMxms Most bugs I deal with on a daily basis are caused by some JavaScript library or the other randomly breaking :/

Slide 64

Slide 65

Slide 65 text

Q: Are we not encouraging people to continue using old browsers by supporting absence of Javascript?

Slide 66

Slide 66 text

People don’t use old browsers out of choice, and it is far more important for a website to ful l its purpose/promise.

Slide 67

Slide 67 text

In July 2013, there was a lot of discussion on the web about the relevance of progressive enhancement.

Slide 68

Slide 68 text

Some people have inaccurate notions.

Slide 69

Slide 69 text

Progressive enhancement is not about making websites for the most basic systems. It’s about starting with the most basic systems in mind.

Slide 70

Slide 70 text

So no one’s asking you to not use Javascript.

Slide 73

It’s okay if a website looks di erent on di erent browsers.

Slide 74

Slide 74 text

We write code that run on client systems.

Slide 75

Slide 75 text

We shouldn’t ignore the known unknowns.

Slide 76

If we start listing the known unknowns, we’ll almost immediately start feeling helpless about the situation.

Slide 77

e thought of not being in control is scary.

Slide 78

How can you control something that is changing all the time?

Slide 79

Slide 79 text

Don’t control it, embrace it.

Slide 80

Slide 80 text

John Allsopp A Dao of Web Design e control which designers know in the print medium, and o en desire in the web medium, is simply a function of the limitation of the printed page. We should embrace the fact that the web doesn’t have the same constraints, and design for this exibility.

Slide 81

Je Bezos Find the things that won’t change in your business and invest heavily in those things.

Slide 82

Focus on functionality and content out design.

@lukew Perhaps ironically the more backwards compatible your web site is, the more future friendly it is.
