Quotable Quotes

Books to the ceiling,

Books to the sky,

My pile of books is a mile high.

How I love them! How I need them!

I'll have a long beard by the time I read them.

Arnold Lobel

 

There is not now, nor has there ever been, nor will there ever be, any programming language in which it is the least bit difficult to write bad code.  Flon's Law

 

The more you give people, the more complacent they become. History, though, tells us how lucky we are.  Dave Hendon

 

The practitioner of . . . programming can be regarded as an essayist, whose main concern is with exposition and excellence of style. Such an author, with thesaurus in hand, chooses the names of variables carefully and explains what each variable means. He or she strives for a program that is comprehensible because its concepts have been introduced in an order that is best for human understanding, using a mixture of formal and informal methods that reinforce each other.  –Donald Knuth, “Literate Programming” (1984)

 

All of the great leaders have had one characteristic in common: it was the willingness to confront unequivocally the major anxiety of their people in their time. This, and not much else, is the essence of leadership.  –John Kenneth Galbraith

 

The most amazing achievement of the computer software industry is its continuing cancellation of the steady and staggering gains made by the computer hardware industry.  Henry Petroski

Software Development Process and Methodology

Article:  What Managers Can Do To Support Agile Transformation

Agile development is everywhere.  Or, at least, that’s what it seems like.  But just slapping the “agile” label on a process doesn’t change culture.  Agile implementations must be intentional and require some fundamental changes to organizational culture.  This article explores the role that development management, both front-line and senior levels, have in successfully implementing agile development.

Software Testing & Quality

Article:  Beyond “More Testing”: Strategies for Powerful Risk Reduction

While defect-free software is perhaps possible (see proofs of correctness, but remember Donald Knuth’s famous axiom:  Beware of bugs in the above code; I have only proved it correct, not tried it.), most of us would not be willing to pay for it.  So what can we do to improve the quality and reduce defects?  I’ve long been a proponent of “risk-based testing”, which uses techniques to balance the likelihood of a problem against the costs of the error occurring and the cost to detect the problem.  This article explains how to apply risk-management principles to testing.

Article:  Let's train our testers early by offering college majors in Software Testing

By noting that software testers and programmers/developers need to have different skill sets, especially in the non-technical areas, this author proposes that, rather than using a one-size-fits-all approach, colleges should have special curriculum for software testing.

Reference:  Explain Shell

If you’re a casual Unix/Linux shell user (or maybe even a very skilled one!), you are bound to run across a shell command that just doesn’t make a lot of sense, especially those with lots of switches and options.  And paging through the man pages can be frustrating too.  Well, just paste in the command at Explain Shell and it’ll give you a breakdown of the command with pointers to each of the items.  It’s based on the Ubuntu man pages archive and includes data from nearly 30000 listings, so it’s comprehensive and up to date.

Very Good Advice From Bill Watterson, in Comic Strip Form

Maybe this really belongs above in the “Career Development/Miscellaneous” section, but its inspirational, yet humorous nature pushed me to put it here… Many of you are probably “Calvin and Hobbes” comic fans. This comic strip in the excellent style of Bill Watterson captures a speech that he gave over 20 years ago to some college graduates about following your dreams.

This Really Exists: Giant Concrete Arrows That Point Your Way Across America

In the days before radar and reliable radio communications, the US air mail system used a series of large concrete arrows painted yellow to mark the transcontinental route.  While sometimes we think innovation only happens in the technology domain, this shows us that simple solutions are often best.

Artist pranks LA Best Buy stores with 'useless' gadget

In an effort to call attention to our unhealthy fascination with gadgets, an artist placed an empty plastic box on display at 5 Best Buy locations.  The “device” was named "Useless Plasticbox 1.2” and it’s “warranty” terms included “no warranty with this piece of crap”.  Funny and a sad cultural commentary at the same time.
