increasing speed of Apple

Apple Inc. hasn't done much talking about Snow Leopard, the next-generation update to Mac OS X that's due to be released in 2009 (possibly within the first quarter of the year). But in what came as a surprise to many, the company has said that the new operating system will contain a limited number of new features.

It seems clear that Apple's biggest focus with Snow Leopard is slimming down and speeding up its flagship operating system -- both of which are attractive to any computer user. But why wait until Snow Leopard ships? There are a number of ways you can slim down and speed up your machine right now.

The lesson, Marissa said, is that speed matters. People do not like to wait. Do not make them.

On the web, speed matters. I see it with campaigns all the time.

This conclusion may be surprising -- people notice a half second delay? -- but we had a similar experience at Amazon.com. In A/B tests, we tried delaying the page in increments of 100 milliseconds and found that even very small delays would result in substantial and costly drops in revenue.

DTI is a variant of magnetic resonance imaging (MRI) that can measure the structural integrity of the brain's white matter, which is made up of cells that carry nerve impulses from one part of the brain to another. The greater the structural integrity, the faster nerve impulses travel. >Personal Note: I worked with DTI during my internship at the MRRC (Magnetic Resonance Research Center) at Yale University. Our signals looked more similar to the second image except that we didn't have a 3d model extracted from the raw signal (the second one shows a raw DTI signal with an overlay of its 3d model representation).

Speed Tracer is a Google Chrome extension that enables developers to identify performance problems in their web apps using a "Sluggishness Graph," in combination with many other metrics.

12/08/2009 07:14:00 PM Do you ever wonder what's going on inside the browser when a webpage doesn't load or respond as quickly as it should? Many developers do, especially when trying to build powerful web applications for their users. But up until now, it's been difficult for developers to identify problems in a slow-to-respond application. So, tonight at Google Campfire One, we're happy to announce that we're adding a new tool to Google Web Toolkit called Speed Tracer. Speed Tracer is a Google Chrome extension that enables developers to identify performance problems in their web apps using a "Sluggishness Graph," in combination with many other metrics. In the spirit of clean, simple design, developers need only look at the Y-Axis of their application's Sluggishness Graph to see how they're doing: * If the y-axis is close to zero, then the app is fast * If the y-axis registers around 100%, then the app is, well, sluggish And in either case, Speed Tracer provides lots of ad

Increase Firefox speed by 10-30x

The two most important pieces of advice I can give on speeding up browser scripts, then, are: 1. Never hand-parse a string. 2. Don't do DOM operations in loops (and in general, don't do DOM operations!).

1. Never hand-parse a string. 2. Don't do DOM operations in loops (and in general, don't do DOM operations!).

I like things that go fast, and that includes code that runs fast. With JavaScript (and Java, too), that can be a challenge. So much the better, though. I like challenges too. When someone asks me what's the single best way to speed up "a slow script," naturally I want to know what the script is spending most of its time doing. In browser scripting, it's typical that a "slow" script operation either involves tedious string parsing of some kind, or DOM operations. That's if you don't count programmer-insanity sorts of things, like creating a regular expression object over and over again in a loop.

Analyses ways to make your Windows startup faster

Does your Windows machine take a long time to boot up? (Insert snarky “switch to Linux” joke here). Well a company has developed a remedy to improve Windows boot time, and it is called Soluto. The way the application works is simple. It installs, then it asks you to reboot and then it watches your boot time and tells you what is taking up the majority of that time. It allows you to pause the item (does not start up again until un-paused) or you can delay its startup. It will wait until the initial set of applications is loaded before attempting to start your delayed applications. This program works well for techies and entry level computer users alike. If you are an expert user you can take action on all your items and have a great list to work from on speeding up your boot up. A novice would be able to pause the items that they know they do not use or have already uninstalled. -makeuseof

CSS-Tricks | how efficient is the CSS that we write, in terms of how quickly the browser can render it?

ably decrease load times for a significant chunk of your users just by adding one line of code to your HTML. Pretty cool, huh?

interesante tecnica.

One of the lesser-known jewels of HTML 5 is link prefetching. The idea is to extend the time-honored concept of image preloading to HTML content (and without any messy AJAX code). Here’s how it works: You add a line like this to your page: <link rel="next" href="page2.html"> Then the browser automatically downloads page2.html in a background process as soon as the user’s computer is idle. When the user finally clicks a link to page2.html, the browser serves it from the cache, and so it loads significantly faster. Link prefetching is currently only supported by Firefox. But since Firefox is the second most popular web browser in the world, you can noticeably decrease load times for a significant chunk of your users just by adding one line of code to your HTML. Pretty cool, huh?
