When you're diving into the history of computing and its concepts, you rarely have to look much further back in time than the Second World War. It happens sometimes, but not that often. However, there are exceptions - and this is one that really boggles the mind: the pixel? One of those little dots on your screen? It's well over 400 years old.

"I'm about to tell you a true story. It's not about me (honest). I have this friend who submitted an application to Apple for review. After a few weeks, it came back with one of those embarrassingly stupid rejection letters that said more about the person reviewing the application than it did about the application itself. In a nutshell, the application violated one of those user interaction rules that seem to exist in certain pompous minds rather than in the actual Apple Human Interface Guidelines. After a day or so of calming down, this person decided to go ahead and resubmit the application. And did so without making a single change to the application. I'm sure you know where this is going."

"After what were surely a few extra pots of coffee last night, Apple released iPhone OS 2.2, the latest update to its operating system for the iPhone and iPod touch. As with the 2.1 update just over two months ago, Apple administered a healthy dose of new features and fixes throughout the OS and a handful of applications, many of which we saw previewed over the last couple months. Let's take a look at the most significant changes, some appreciated polish, and recap what's still missing."

IBM Research has uncovered work it is doing to bring the brain's processing power to computers, in an effort to make it easier for PCs to process vast amounts of data in real time. The researchers want to put brain-related senses like perception and interaction into hardware and software so that computers are able to process and understand the data quicker while consuming less power, said Dharmendra Modha, a researcher at IBM. The researchers are bringing the neuroscience, nanotechnology and supercomputing fields together in an effort to create the new computing platform, he said.

Last month we covered an article titled, "MSI: Wind Doing Well, Linux Version Not So Much" which revealed that Linux MSI Wind netbooks saw a return rate upto four times higher than the Windows equivalent. But in a recent interview with the CEO of Asus he revealed that Linux and Window versions of Asus Eee PC have similar return rates. He also described the plans for 2009 and talked about some changes to come in the Operating System for the netbooks.

What's after electrical charges and electricity in computer storage? Lasers and excitons. Theorists from the John Hopkins University have drafted a theory that uses low-power lasers and crystalline insulators to store data. In the theory, lasers would excite electrons in a crystalline-like lattice in order to record data; the atoms would vibrate at a certain frequency to indicate the type of bit. A side effect of using lasers and insulators is reduced heat output. The heat is reduced because the atoms do not exchanging electrons as current computer components do. The EE Times has a more detailed write up as well as WebIndia, TopNews.in, Eureka Alert, and Small Times.

Microsoft plans to offer one more public test version of Internet Explorer 8 before releasing the final version of the updated browser, the company said late Wednesday. The next test, essentially a "release candidate" version will come in the first quarter of 2009. That means the final release won't hit Microsoft's initial goal of finishing the browser this year. "Our next public release of IE (typically called a "release candidate") indicates the end of the beta period," general manager Dean Hachamovitch said in a blog posting, "We want the technical community of people and organizations interested in Web browsers to take this update as a strong signal that IE8 is effectively complete and done."

Every now and then, an article pops up which argues that it would make sense for Microsoft to offer a free, ad-powered version of Windows. "We are all aware that Google is the king of online advertising. Microsoft has wanted to compete in that space forever, which is why giving away Windows 7 makes so much sense," Business Pundit argues, "Let's look at the numbers; Microsoft's operating systems are on 90% of the world's computers, or roughly one billion machines. That's penetration on a massive scale. Even Google has to be impressed." While these articles make some valid points, they rarely dive into the actual details.

Arjan van de Ven from Intel Open source centre has posted the news that http://kerneloops.org has recorded its 100,000 oops. An oops in the Linux kernel is a deviation from correct behavior of the Linux kernel which produces a certain error log. kerneloops is a client side software that helps record oops more automatically on the website with the same name and is available as part of many distribution repositories and even included by default in Fedora. This is part of the QA efforts in the Linux kernel and when posting the news, Arjan has noted that Linux kernel developers have been fixes most of the top oopses quickly

Two years ago, Microsoft and Novell inked a landmark deal on patents and Linux-to-Windows interoperability. According to Microsoft and Novell, it's a deal that has shown dramatic momentum in its second year, with a triple digit percentage increase in customers for a total tally of more than 200 customers. "I was surprised at the number of over 200 customers, so I actually went back and double checked it just to make sure," Susan Heystee, General Manager for Global Strategic Alliances at Novell told InternetNews.com. "That represents over 250 percent growth in terms of the number of customers that are part of the partnership which is really great. A real positive surprise has been the great customer momentum."

Linux and other Unix-like operating systems use the term "swap" to describe both the act of moving memory pages between RAM and disk. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?

Royal Pingdom blog has posted with a comparison of home page load times and uptimes and concludes that various Linux distributions and Apple, both beat Microsoft's record.

• 13/16 Linux distributions (and Apple) had less downtime than Microsoft's homepage.
• 5/16 Linux distributions had less downtime than Apple's homepage.
• Four homepages had NO downtime: Red Hat, Mepis, Knoppix and Fedora.
• Five homepages had more than an hour of downtime: Gentoo, Mandriva, Mint, Arch and Microsoft.

Red Hat has announced a new program where customers would get higher service level guarantees and updates for up to 10 years for a new release instead of the usual 7 years for every release. "The targets for this are the most conservative companies currently on Unix-based systems and with a need for unusual levels of support," said Scott Crenshaw, vice president of Red Hat's Platforms business unit.

From MacRumors: "Apple's Director of Engineering of Unix Technologies Jordan Hubbard spoke at LISA '08 last week. This year's conference invited Apple's Jordan Hubbard to speak about the evolution of Mac OS X from large servers to embedded platforms". The presentation slides (PDF), besides generally interesting info on Mac OS X, feature a table that shows a release date of Q1 2009 for OS X 10.6 Leopard.
