A few mathematical abilities are crucial for engineering and technological know-how classes. commonly it is going to be assumed that those talents have already been mastered, and except so, you will turn into misplaced in additional examine. realizing those talents is something; remembering them to be able to be essentially utilized is completely one other. This ebook isn't right here to educate those essentials—it isn't a textbook—but is meant to aid drum them in and preserve them there for destiny use.

A part of the thrill of programming in Perl lies in tackling tedious initiatives with brief, effective, and reusable code. usually, the right instrument is the one-liner, a small yet robust software that matches in a single line of code and does something quite well.
In Perl One-Liners, writer and impatient hacker Peteris Krumins takes you thru greater than a hundred compelling one-liners that do every kind of convenient issues, comparable to manage line spacing, tally column values in a desk, and get an inventory of clients on a approach. This cookbook of helpful, customizable, and enjoyable scripts may even aid hone your Perl coding talents, as Krumins dissects the code to provide you a deeper figuring out of the language.
You'll locate one-liners that:
- Encode, decode, and convert strings
- Generate random passwords
- Calculate sums, factorials, and the mathematical constants π and e
- upload or eliminate spaces
- quantity strains in a file
- Print strains that fit a particular pattern
- fee to work out if a bunch is key with a standard expression
- Convert IP handle to decimal form
- exchange one string with another
And many extra! keep time and sharpen you coding talents as you discover ways to triumph over these pesky projects in a couple of accurately put keystrokes with Perl One-Liners.

This pleasant and instructive background of invention exhibits why nationwide Public Radio dubbed Tenner “the thinker of daily technology.” how our innovations have impacted our global in methods we by no means meant or imagined, he exhibits that the issues we create tend to bop again and alter us.
The reclining chair, initially designed for short, healthy rest, has turn into the very image of weight problems. The helmet, invented for army reasons, has made attainable new activities like mountain cycling and rollerblading. The typewriter, created to make enterprise run extra easily, has ended in widespread imaginative and prescient difficulties, which in flip have made humans extra reliant on one other invention—eyeglasses. As he sheds gentle at the many ways innovations shock and renew us, Tenner considers the place expertise will take us sooner or later, and what we will be able to count on from the units that we now not appear capable of reside with no.

Access to technological know-how and know-how around the world is accomplished through energetic participation in open foreign clinical study, in addition to via technological potential that's decisive in catching up with global advancements in technology and know-how. In different phrases, it's the "national process of innovation" which determines a country's assimilation ability. the schools, learn associations, the technological infrastructure, commercial education schemes, info networks and technical associations regularly give you the beginning for a high-quality, regular improvement. accordingly regulations directed towards strengthening the nationwide procedure of innovation are crucial for a catching-up approach. yet much more vital is the presence of expert and skilled individuals with the required connections to the clinical and technological infrastructure of the area at huge. this is applicable to China specifically. even if the technological strength should be constructed, relies on the technological and business concepts promoted via the chinese language management. additionally, the prices and advantages of technological improvement are suffering from the customary evolutionary level of a country's political framework and financial regime. There needs to be a powerful coordination among total fiscal regulations and know-how coverage. A sucessful administration of expertise is simply attainable via a "technological package deal" together with administration, monetary and advertising and marketing skills.

Predictive know-how version for powerful Nanoelectronic layout explains a number of the technical mysteries at the back of the Predictive know-how version (PTM) that has been followed around the world in explorative layout examine. via actual derivation and know-how extrapolation, PTM is the de-factor machine version utilized in digital layout. This paintings explains the systematic version improvement and offers a consultant to powerful layout perform within the presence of variability and reliability concerns. Having interacted with a number of best semiconductor businesses and college examine groups, the writer brings a cutting-edge viewpoint on expertise scaling to this paintings and stocks insights won within the practices of machine modeling.
