High Performance Web Sites

giovedì, 24 gennaio 2008 21.34 by Marco Bellinaso

High Performance Web Sites è un libro scritto da Steve Souders con l'intento di insegnare a chi sviluppa il front-end di siti web come renderli veloci e scalabili. Il testo evidenziato sta ad indicare come il libro non tratti argomenti quali la progettazione e il tuning del DB, l'utilizzo o meno di transazioni, il caching dei dati ecc. ecc. -- ovvero tutte tecniche per lo sviluppatore server-side -- ma si concentri su ciò che riguarda HTML, CSS, JavaScript, AJAX...quello che si vede insomma. Dal momento che l'autore lavora in Yahoo! dal 2000 occupandosi proprio di questi aspetti, e a giudicare dalle recensioni presenti su Amazon, sembra proprio un ottimo libro, prezioso se il vostro sito continua ad incrementare (o sperate che incrementi in futuro) il traffico.

Detto questo, devo dire però che già leggendo il sommario si possono estrarre le "regole d'oro di base" trattate nel libro:

1) Make Fewer HTTP Requests
2) Use a Content Delivery Network
3) Add an Expires Header
4) Gzip Components
5) Put Stylesheets at the Top
6) Put Scripts at the Bottom
7) Avoid CSS Expressions
8) Make JavaScript and CSS External
9) Reduce DNS Lookups
10) Minify JavaScript
11) Avoid Redirects
12) Remove Duplicates Scripts
13) Configure ETags
14) Make Ajax Cacheable

Se non volete spendere neanche i miseri 20$ del libro, usando Google potete trovare tutte le info che vi servono per approfondire ciascuno di questi punti.

One of my first jobs as a new Army lieutenant in Vietnam was to build a road
across a rice paddy. Progress was slow because the paddy devoured most of the dirt we laid down. My superior officer, a major, appeared one day, determined to speed things
up.

His solution was to scrape the crust off the top of the paddy and with it, construct the road. He quelled my protestations with a stern, �Lieutenant, *I'm* in charge.�

He ordered a bulldozer into the paddy, but the massive monster sank in the muck. Undaunted, the major ordered another dozer to help the first one out. It, too, was soon
stuck. After a long silence, the major got into his jeep. His departing words were,
�Lieutenant, you're in charge.�

A blind man and his guide dog enter a bar and find their way to a barstool.

After ordering a drink, and sitting there for a while, the blind guy yells to the bartender, "Hey, you wanna hear a blonde joke?"

The bar immediately becomes absolutely quiet.

In a husky, deep voice, the woman next to him says, "Before you tell that joke, you should know something, the bartender is blonde, the bouncer is blonde, and I'm a 6' tall, 200 lb. blonde with a black belt in karate.

What's more, the woman sitting next to me is blonde and she's a weight lifter. The lady to your right is a blonde, and she's a wrestler. Think about it seriously, Mister. You still wanna tell that joke?"

The blind guy says, "Nah, not if I'm gonna have to explain it five times."

cheapest world of warcraft gold

A redhead, a brunette, and a blonde robbed a supermarket. As they were stealing, a police officer walked in the store and saw what was happening. He dashed toward them, but they were able to get away into the back of the store. There they found three sacks to hide in. When the police officer checked there, he examined each sack.

He kicks the first bag, and the redhead says "meow" in a high voice. The cop determines that it must only be a cat in that bag, and he moves on to the next.

When he kicks the second bag, the brunette says "woof" in a low voice. The officer determines that it must only be a dog in that bag, so he moves on to the last bag.

He kicks the third bag, and the blonde shouts "potato" to the officer.
