We already know there are tools to measure how fast a program runs. There are programs called profilers which measure running time in milliseconds and can help us optimize our code by spotting bottlenecks. While this is a useful tool, it isn't really relevant to algorithm complexity. Algorithm complexity is something designed to compare two algorithms at the idea level — ignoring low-level details such as the implementation programming language, the hardware the algorithm runs on, or the instruction set of the given CPU. We want to compare algorithms in terms of just what they are: Ideas of how something is computed. Algorithm complexity is just a way to formally measure how fast a program or algorithm runs.

Err... no, that's completely wrong.
Algorithm complexity has almost nothing to do with how fast the algorithm runs.
How fast an algorithm runs depends on the machine it's running on, the language it's written in, how well the algorithm has been coded, and many other factors besides.
Algorithm complexity is a measure of how difficult it is to derive the algorithm outputs from the inputs.

but the main reason anybody cares about algorithmic complexity (outside of pure academic research) is because studying an algorithm, determining its complexity, and then searching for a simpler method, is a path to performance gains. end users, library callers and QA testers do not care how "difficult" the algorithm is, they just want the algorithm to turn input into output as fast as possible.

Complexity is a pretty generic term. Perhaps it's algorithm performance complexity vs algorithm design complexity. Though, the term "complexity" does imply nuance more than magnitude. Maybe a better term would be "algorithm efficiency".

Daniel Clifford recently gave a great talk at Google I/O 2012 called “Breaking the JavaScript Speed Limit with V8″. In it he goes in depth to explain 13 simple optimizations you can do in your JavaScript code to help Chrome’s V8 JavaScript engine compile / run your JavaScript code faster. In the talk he gives a lot of great explanations as to what they are and why they help, but if you just want the quick and dirty list, here goes... Better than it ran before. Better, stronger, faster...

Some developers waste time waiting for their employer to train them on new technology or complaining they aren’t getting the training to stay current. While companies continue to cut training budgets, every developer should take the initiative to educate themselves, especially with so many free resources available on the web. When a developer takes risks like this, everyone on a team benefits. You really need to come out of the dark ages of software development.

The Internet was designed to be robust, fault-tolerant and distributed, but its technology is still in its infancy.
The fact that the Web has not stopped functioning in its initial decades sometimes encourages us to assume that it never will. But like any system, biological or man-made, the Internet has the potential to fail. Don't be too proud of this technological terror you've constructed.

Apple didn’t cut the iPad from whole cloth (which probably would have been linen). It was built upon decades of ideas, tests, products and more ideas. Before we explore the iPad’s story, it’s appropriate to consider the tablets and the pen-driven devices that preceded it. From the Dynabook to the future.

PCs are more complicated and less reliable than they should be. They require too much maintenance, like a car that requires you to top off the oil, check the tire pressure and fill the gas tank on every trip. Even though they use chips that are far more powerful than the ones in the iPad, they’re often much slower. They rarely have built-in wireless broadband. Every moment I spend dealing with this stuff is a moment I’m not spending creating content. I find that deeply frustrating. Is the iPad good for content creation as well as content consumption?

I'd argue that the last truly revolutionary version of Windows was Windows 95. In the subsequent 17 years, we've seen a stream of mostly minor and often inconsequential design changes in Windows – at its core, you've got the same old stuff: a start menu, a desktop with icons, taskbar at the bottom, overlapping windows, toolbars, and pull-down menus.... Windows 8 is, in my humble opinion, the most innovative version of Windows Microsoft has released since Windows 95. What's good about Windows 8? A ton of stuff.

I'd argue that the last truly revolutionary version of Windows was NT4.
It marked the transition from a personal OS to a business-capable OS - Win95 was more revolutionary with it's UI changes, but NT4 was the game-changer for MS.

NT4 brought a lot to the table, but I thought Win2k brought the best parts of NT to an OS that was better suited to day-to-day desktop use.

Today at the annual Worldwide Partner Conference in Toronto, Canada, Microsoft shared the details about the upcoming Windows Milestones with its partners. The Windows Chief Marketing Officer and Chief Financial Officer Tami Reller provided details on Windows 8 General Availability.
Windows 8 is on track and all set to Release to Manufacturing (RTM) in the first week of August. The enterprise consumers with Software Assurance benefits will have early access to RTM or final build of Windows 8 in August.

Apple co-founder Steve Wozniak quips Steve Jobs "came back reincarnated at Microsoft" referring to the Redmond-based company's recent design breakthroughs that have culminated in the new Surface, a tablet which sports a marriage of art and technology reportedly befitting of the late tech guru
Haven't he said that about Windows phone already?

On a somewhat related note... I chanced upon a Windows phone last night and came away pretty impressed. This 1 month old LG phone (probably an Omnia variant)fared better than my 3 month old Galaxy 3 in terms of responsiveness and overall graphics.

Do you find all the apps you want?
I'm getting a new phone in december so I'm interested in knowing if you find all you want.

I already have the Samsung Focus (AKA Omnia) running WP7.5. By December, the new WP8 phones should be hitting the shelves. Expect the next gen Lumia to be scrummilicious.

From what I have read, most people only really use a few apps. Tons of apps do no good if they don't do what you want. How many apps does one tend to use on a PC, and that is an environment that is a lot easier to use (but a lot harder to carry around).

Looks like they finally got their own Audible app so now it appears pretty complete. If that had happened sooner i'd probably be using my wp7 now instead of my shiny new droid.

If you already have an idea of what you want to be able to do you can always search the marketplace to see if it's there. So far, there are over 100,000 apps but if the kind of thing you want to do is not there it doesn't matter whether there are 5 apps or a million.
