Procedural programming has been around since the
inception of computers and programming. Object–oriented
paradigms arrived a little later — in the late 1950s to early 1960s
— which means over 50 years of object–oriented problem solving.
Still, many developers lack a full understanding of the thought
process in developing object–oriented software and therefore can't
take advantage of its concepts. I'm happy to see that this book, The
Object–Oriented Thought Process, has taken this fairly old
perspective and given it full attention and renewed interest.
Not having read the previous editions, I'm not familiar
with the changes represented in this fourth edition. Author Matt
Weisfeld is a professor who understands these important concepts
and the level of knowledge and process required for readers and
students to grasp what they need to know. The examples in the book
are concise, clear, and easy to follow. Additionally, the book makes
good use of white space, lists, pictures, and diagrams to make the
content easier to follow and scan quickly.
Weisfeld has organized the concepts to build on each
other, ensuring that students understand one concept well before
moving to the next. On the other hand, readers who already
understand the fundamentals can go directly to object–oriented
thought processes for particular programming paradigms, such as
Web services or client–server applications.
The book is language–neutral. Its examples are in C#, but
a supplementary website offers example code in other languages. If
your language isn't fairly represented, don't be deterred from
acquiring this book because object–oriented concepts and semantics
are mostly universal — just the particular implementation might
vary due to the language.
Each chapter contains UML and example code to better
understand the concepts and see how they're implemented. The last
chapter introduces design patterns but without going into great
detail about how to use them. This lets the inexperienced reader
know that design patterns would be the next step in the path to
developing good code.
Overall, I can recommend this book to code developers,
designers, and testers — to anyone with an interest in proper
software development semantics. It's available in a digital format
that serves as a useful ready reference.

Under our feet, cables carry data between our homes,
offices and data centers at a pace that can match the speed of light.
The data travels as light that runs through strings made of materials
like glass and plastic.
Researchers at the University of Maryland want to do away
with the cable altogether and just use air to guide the light. That's
not as simple as it sounds, because a laser sent through air will
spread apart and interact with particles, gradually losing its intensity
over time.
The research team instead caused patches of air to mimic
a fiber optic cable by creating tubes of dense air surrounded by
low–density air. In a fiber optic cable, a laser travels through a
string of glass. When it tries to leave the glass, it hits a wall that
reflects it back into the center, guiding it along the length of the
cable. The cable made of air works in the same way.
“It's like you could just take a physical optical fiber and
unreel it at the speed of light, put it next to this thing that you want
to measure remotely, and then have the signal come all the way
back to where you are," University of Maryland team lead Howard
Milchberg said in a release.
Signals that traveled through the air cable were 1.5 times
stronger than when they were sent through plain air. The team was
able to send them over a distance of three feet and is now interested
in pushing the range to 150 feet.
If the University of Maryland team succeeds, the air cables
could be used for communication in remote locations on Earth
where laying fiber optic cables is extremely difficult, or places
where it actually is impossible like space. NASA is already
experimenting with laser communication between the International
Space Station and Earth. The technique could also be used to probe
the Earth to make topographic maps or examine the chemicals
present in hard–to–reach places like the atmosphere or a nuclear
plant.
