Book Name: Think like a programmer
Writer: V. Anton Spraul
This book is about critical thinking, however
what is critical thinking, precisely? When
individuals utilize the term in
standard discussion,
they frequently mean something
g altogether different from
what we mean here. In the event that your
1997 Honda Civic has blue
smoke originating from the tailpipes
e is sitting generally, and
has lost eco-friendliness, this is a prob
Lem that can be understood with car
information, analysis, substitution eq
uipment, and regular shop instruments. In the event that
you educate your companions concerning your concern, however, one of them may state,
“Hello, you should exchange that old Honda in for something new. Issue comprehended.”
*
In any case, your companion’s proposal wouldn’t generally be a
arrangement
to the issue—it
would be an approach to
maintain a strategic distance from
the issue.
Issues incorporate imperatives, umbrella
kable guidelines about the issue or
the manner by which the issue must be
illuminated. With the separated Civic,
one of the imperatives is that you need
to fix the current ca
r, not buy a
new vehicle. The imperatives may likewise incl
ude the general expense of the fixes,
to what extent the fix will take, or a requ
increment that no new apparatuses can be pur-
pursued only for this fix.

Section 1
When taking care of an issue with a program
m, you likewise have requirements. Com-
mon imperatives incorporate the programming
language, stage (does it run
on a PC, or an iPhone, for sure?), pe
performance (a game program may require
designs to be refreshed in any event 30 ti
mes a second, a business application
might make some most extreme memories reaction to
client info), or memory impression.
Once in awhile the requirement in
evolves what other code
you can reference: Maybe
the program ca exclude certain open
– source code, or mama
ybe the inverse—
possibly it can utilize just open source.
For software engineers, at that point, we can characterize
critical thinking
as composing a unique
a program that plays out a specific arrangement of
assignments and meets every expressed imperative.
Starting developers are
frequently so anxious to achieve the initial segment
of that definition—composing a program
to play out a specific errand—that they
fizzle on the second piece of the definition
on, meeting the expressed
requirements. I call
a program that way, one that
at appears to pr
oduce right outcomes yet break
at least one of the expressed standards, a
Kobayashi Maru
. On the off chance that that name is new
to you, it implies you are deficiently fa
familiar with one of the touchstones of
nerd culture, the film
Star Trek II: The Wrath of Khan
. The film contains a sub-
the plot about an activity for trying offi
cars at Starfleet Academy. The cadets
are put on board a reenacted starship brid
GE and made to go about as commander on a
crucial includes an unthinkable ch
dice. Guiltless individuals will kick the bucket on a
injured boat, the
Kobayashi Maru
, yet to contact them
requires beginning a
fight with the Klingons, a fight that
can just end in the annihilation of the
skipper’s boat. The activity is proposed
to test a cadet’s fortitude enduring an onslaught.
It’s absolutely impossible to win, and all decisions
lead to terrible results. At the end
of the film, we find that Captain Ki
RK changed the recreation to make it
all things considered winnable. Kirk was cunning, however, he didn’t understand the difficulty of the
Kobayashi Maru
; he maintained a strategic distance from it.
Luckily, the issues you will fa
ce as a developer are resolvable,
in any case, numerous developers despite everything resort to Kirk
‘s approach. At times, they do
so unintentionally. (“Goodness, shoot! My answer possibly works if there are a hundred
information things or less. It should work
RK for a boundless informational index. I’ll have
to reconsider this.”) In different cases, the
expulsion of limitations is intentional, a
a ploy to comply with a time constraint forced by a
a chief or a teacher. In still other
cases, the software engineer simply doesn’t have the foggiest idea
the most effective method to meet the entirety of the limitations.
*
In the most pessimistic scenarios I have seen, the pr
programming understudy has paid somebody
else to compose the program. Notwithstanding
the inspirations, we should consistently be
determined to maintain a strategic distance from the Kobayashi Maru.
Exemplary Puzzles
As you progress through this book, you will see that in spite of the fact that the particu-
lars of the source code change from
one issue zone to the following, certain
examples will rise in the methodologies
we take.
