IPv6 Essentials (2nd Edition)

IPv6 necessities, moment version presents a succinct, in-depth travel of the entire new positive factors and capabilities in IPv6. It publications you thru every thing you must be aware of to start, together with the way to configure IPv6 on hosts and routers and which purposes presently aid IPv6. the hot IPv6 protocols deals prolonged deal with area, scalability, better aid for safeguard, real-time site visitors aid, and auto-configuration in order that even a beginner person can attach a laptop to the web.

High Performance Web Sites: Essential Knowledge for Front-End Engineers

I even have this ebook in EPUB and PDF as retail (no conversion).

Want to hurry up your site? This ebook offers 14 particular principles that may reduce 20% to twenty-five% off reaction time while clients request a web page. writer Steve Souders, in his task as leader functionality Yahoo! , accumulated those most sensible practices whereas optimizing the various most-visited pages on the internet. Even websites that had already been hugely optimized have been capable of take advantage of those unusually easy functionality guidelines.

Want your website to show extra speedy? This booklet offers 14 particular principles that may minimize 25% to 50% off reaction time while clients request a web page. writer Steve Souders, in his task as leader functionality Yahoo! , accumulated those most sensible practices whereas optimizing the various most-visited pages on the internet. Even websites that had already been hugely optimized, corresponding to Yahoo! seek and the Yahoo! entrance web page, have been in a position to take advantage of those strangely easy functionality guidelines.

The principles in excessive functionality websites clarify how one can optimize the functionality of the Ajax, CSS, JavaScript, Flash, and photographs that you've already outfitted into your website -- changes which are serious for any wealthy internet program. different assets of knowledge pay loads of recognition to tuning internet servers, databases, and undefined, however the bulk of exhibit time is taken up at the browser part and by means of the verbal exchange among server and browser. excessive functionality websites covers each element of that process.

Each functionality rule is supported through particular examples, and code snippets can be found at the book's significant other site. the principles comprise how to:

Make Fewer HTTP Requests
Use a content material supply community
upload an Expires Header
Gzip elements
placed Stylesheets on the most sensible
placed Scripts on the backside
keep away from CSS Expressions
Make JavaScript and CSS exterior
lessen DNS Lookups
Minify JavaScript
stay away from Redirects
eliminate Duplicates Scripts
Configure ETags
Make Ajax Cacheable

If you're construction pages for prime site visitors locations and wish to optimize the adventure of clients traveling your website, this e-book is indispensable.

"If every body may enforce simply 20% of Steve's guidance, the internet will be a dramatically larger position. among this ebook and Steve's YSlow extension, there's rather no excuse for having a gradual site anymore. "

-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector

"Steve Souders has performed an exquisite activity of distilling a major, semi-arcane paintings right down to a suite of concise, actionable, pragmatic engineering steps that may swap the realm of net functionality. "

Soft Computing Applications in Business

Tender computing thoughts are favourite in such a lot companies. This ebook involves a number of vital papers at the functions of soppy computing innovations for the company box. The gentle computing innovations utilized in this ebook comprise (or very heavily comparable to): Bayesian networks, biclustering equipment, case-based reasoning, facts mining, Dempster-Shafer conception, ensemble studying, evolutionary programming, fuzzy selection timber, hidden Markov types, clever brokers, k-means clustering, greatest chance Hebbian studying, neural networks, opportunistic scheduling, chance distributions mixed with Monte Carlo tools, tough units, self organizing maps, help vector machines, doubtful reasoning, different statistical and computing device studying suggestions, and mixtures of those suggestions.

Computing the Optical Properties of Large Systems

This paintings addresses the computation of excited-state homes of structures containing millions of atoms. to accomplish this, the writer combines the linear reaction formula of time-dependent density useful conception (TDDFT) with linear-scaling concepts identified from ground-state density-functional conception.

Oceanic vertical velocity at 100 m. Blue/red denotes upward/downward currents. 28 S. Masson et al. 3 Oceanic CO2 pumping and eddies The capacity of the ocean to pump or reject CO2 is a key point to quantify the climatic response to the atmospheric CO2 increase. Through biochemistry processes involving life and death of phyto and zooplankton, oceans reject CO2 to the atmosphere in the equatorial regions where upwelling are observed, whereas at mid and high latitudes, oceans pump and store CO2. It is thus primordial to explore the processes that keep balance between oceanic CO2 reject and pumping and understand how this equilibrium could be affected in the global warming context: Will the ocean be able to store more CO2 or not?
