Jeremy M. Jones
Jeremy M. Jones是一名软件工程师,现任职于Predictix。他选择的开发工具是Python,而他对shell、Perl也有一定研究,了解Java的相关知识,当前在学习C#。他对函数式编程语言(尤其是OCaml)非常感兴趣。
他是开放源码项目Munkware的开发者,Munkware是一个多生产者/多消费者、事务性、持久队列机制的项目;他还是ediplex的开发者,ediplex是一个EDI(电子数据交换)解析引擎。此外,他也是podgrabber的开发者,podgrabber是一个podcast下载器。以上三个项目都是由Python语言编写。
Jeremy将他的空闲时间花在家庭生活和写作上。他和他的妻子Debra以及两个孩子Zane和Justus住在Georgia(Atlanta的东部)的Conyers,那里有一个名为Genevieve的实验室。
Jeremy所表达的想法和观点仅代表他个人,不代表Predictix的观点。
Jeremy M. Jones is a software engineer who works for Predictix. His weapon of choice
is Python, but he has done some shell, plenty of Perl, a touch of Java, is currently
learning C#, and finds functional programming languages (especially OCaml)
fascinating.
He is the author of the open source projects Munkware, a multiproducer/multiconsumer,
transactional, and persistent queuing mechanism; ediplex, an EDI (electronic
data interchange) parsing engine; and podgrabber, a podcast downloader. All three
projects were written in the Python language.
Jeremy spends his spare time enjoying his family and doing a little writing. He lives in
Conyers, Georgia (just east of Atlanta) with his wife, Debra, two children, Zane and
Justus, and a lab named Genevieve (how Madelinesque).
Opinions and views expressed by Jeremy are his own and not those of Predictix.
The image on the cover of Python for Unix and Linux System Administration is a boa
constrictor (boa constrictor). Found throughout South and Central America and some
islands in the Caribbean, boa constrictors are non-venomous snakes that can thrive in
a wide array of environments, from deserts to open savannas and wet tropical forests,
but they prefer arid terrain over wet surroundings. They are both terrestrial and arboreal,
but as they get older, they tend to spend more time on the ground.
Boa constrictors have very unique markings that include diamond- and oval-like patterns.
Their scales change colors depending on their habitat, allowing them to hide
from the forest-dwelling animals that hunt them.
In the wild, boa constrictors thrive on small- to medium-size rodents, lizards, bats,
birds, mongooses, squirrels, and have even been known to feast on other mammals as
large as ocelots. Being cold-blooded and slow moving, boas can go up to a week without
eating after capturing large prey. They are solitary and nocturnal hunters, with heatsensitive
pads on their heads to help them hunt. Particularly fond of bats, boas will
hang in trees and from the mouths of caves waiting for them to fly by, then they can
grab the bats with their mouths. Not surprisingly, boa constrictors kill by constriction.
The snake wraps its body around its prey in coils, tightening its grip each time the victim
breathes out, eventually suffocating it to death.
Boas are a common attraction in zoos, and they are even relatively common pets. In
fact, thousands of dollars are made every year importing them into the U.S. In South
America, they are revered as “destroyers of rodents” and are often domesticated for
that reason. Boa constrictors grow quite tame in captivity and can live there as such for
20–30 years. Hunted for the exotic pet trade and their decorative markings, some boa
constrictors are endangered and have protected status.
Boa constrictors are seasonal breeders. To attract males, females emit a scent from their
cloacas, which is the chamber into which the intestinal and urogenital tracts discharge.
Fertilization happens internally, and females can give birth to up to 60 live babies at
one time. Significantly smaller than their anaconda cousins, newborn boas average 2
feet in length and can grow up to 13 feet long and weigh more than 100 pounds. Found
in South America, the largest boa constrictor on record was 18 feet!
