Since its first publication in 1970 The
Technique of Furniture Making has
established itself as the bible for all
woodworkers.

Introduction
Any textbook concerned with the techniques of furniture-
making must deal primarily with the basic handcrafts for
it is upon this groundwork that machine production is built,
and in fact all the machine can ever do is to translate
the essential hand operations into rotary movements of
the cutting tool.

anyone who has only been shown how to force a piece of
wood against a mechanised saw will have learnt very little,
but if he has had to saw that piece of wood by hand he
will be more likely to know that much more about it, he
will have greater respect for it and will understand in
greater depth the problems that will have to be faced in
its manipulation.

職⼈人気質
The Japanese word shokunin is defined by both
Japanese and Japanese-English dictionaries as
‘craftsman’ or ‘artisan,’ but such a literal
description does not fully express the deeper
meaning.

職⼈人気質
Shokunin means not only having technical skill, but
also implies an attitude and social
consciousness... a social obligation to work his
best for the general welfare of the people, [an]
obligation both material and spiritual.

“Of course you can’t do full-stack JavaScript development (or
full-stack any web development for that matter), without
learning JavaScript itself.”

As for HTML, there’s not much to learn right away
and you can kind of learn as you go, but before
making your first templates, know the difference
between in-line elements like and how they
differ from block ones like
. This will save you a
huge amount of headache when fiddling with your
CSS code.

JavaScript is NOT declarative
Imperative programming focuses on describing how a
program operates.
The term is often used in contrast to declarative
programming, which focuses on what the program should
accomplish without specifying how the program should
achieve the result.

Principle of Least Power
The choice of language is a common design choice.
The low power end of the scale is typically simpler to
design, implement and use, but the high power end of
the scale has all the attraction of being an open-ended
hook into which anything can be placed: a door to
uses bounded only by the imagination of the
programmer.

div
“The div element has no special meaning at all.
Authors are strongly encouraged to view the div element as
an element of last resort, for when no other element is
suitable. Use of more appropriate elements instead of
the div element leads to better accessibility for readers and
easier maintainability for authors.”

“Structured data”
When you add markup to your content, you help search
engines understand the different components of a page.
When Google's systems understand your page more clearly,
Google Search can surface content through the cool features
discussed in this post, which can enhance the user
experience and get you more traffic.

increase of new user registrations from organic traffic,
and 15% lower bounce rate for Google visitors to job
pages.
• Rakuten used the recipe search experience and saw a 2.7X

Schmutza, Sondereggera and Sauera
• Sixty-one participants without disabilities used one of three
websites differing in levels of accessibility
• A high level of web accessibility led to better performance (i.e.,
task completion time and task completion rate) than low or very
low accessibility.
• Likewise, high web accessibility improved user ratings (i.e.,
perceived usability, aesthetics, workload and trustworthiness)
compared to low or very low web accessibility.

“Developer Experience” Bait-and-Switch
We cannot continue to use as much JavaScript as is
now “normal” and expect the web to flourish.
To get this fixed, we need to confront the “developer
experience” bait-and-switch. Tools that cost the
poorest users to pay wealthy developers are bunk.
