How to Install Chrome OS From A USB Drive

Have you already tried Chrome OS using a virtual machine, and were less than impressed? Well now you can get a feel for how Google's Web-centric operating system will run natively on your machine. The folks over at Engadget were able to boot Chromium OS -- the open source version of what will become Chrome OS -- off of a USB stick on a Dell Vostro A90 netbook. The USB bootable disc is based on the Chromium OS build of Twitter user Hexxeh, who set up a Web site where you can view all the instructions you need for getting your bootable USB up and running.

If you're ready to get your hands dirty and try out the new OS, here's what you need to know:

Get the Torrent

Before you do anything, you're going to need to download the Hexxeh's Chromium OS build. You can find a torrent link on Hexxeh's Website or you can use the mirror links found here andhere courtesy of Engadget.

Set Up Your USB Stick

Hexxeh has some easy instructions for writing your Chromium OS image onto a USB stick. The instructions for Windowsand Linux look pretty straightforward, butMac users are going to have a slightly more complicated time.

Pick Your Machine

A major problem with Chromium OS right now is that its device drivers are in the very early stages of development. That means some parts of your computer may not respond when using Chromium OS. One of the most common problems being reported is the lack of Wi-Fi functionality. So you may have to use an Ethernet connection instead. You should also know there's no guarantee the OS will boot up at all.

If you're in the market for a netbook or laptop, and you plan on experimenting with Chromium, check out Google's list of devices that are known to work with the latest version of Chromium OS. The list is primarily for developers who want to work with the new OS, but there's no reason you can't use it as a buying guide. The device index features a sortable checklist that lets you know if the Wi-Fi and trackpad functions are working, as well as general comments and warnings specific to each device.

For example, you might want to stay away from the Asus Eee PC 900 if you plan to run Chrome right now. The netbook's Wi-Fi is supposed to work, but the device's fans may not run, which could cause your system to overheat. Other Wi-Fi-ready devices, according to Google's list, are the Toshiba mini NB205, and the Asus Eee PC 1008HA. The Lenovo ThinkPad T400 may also work after upgrading the Wi-Fi firmware. But before you go out and spend money on a new computer, read over Google's hardware list to make sure you are fully aware of the functionality and problems for the device you have in mind.

Booting From the USB

Once you've got your computer, and have gone through the steps of writing your bootable disc, you may find you can't get Chromium OS to boot on your Windows-based machine. If this happens, you may have to change the settings for how your machine boots up.

You can learn how to change the settings by checking out PC World's guide to installing Windows 7 on a netbook using a USB drive. The instructions are not Chromium-specific, but you should be able to figure out how to adapt this method for your purposes.

A word of warning: Changing the boot order means messing with your system's command prompt and BIOS. If that sounds scary, you might be better off picking up an officialChrome OS machine later next year. For the rest of you, let us know in the comments how Chromium is running on your netbook.

Intel Core i5, Core i7 800 Processors and P55 Express

With today's launch of their new "Lynnfield" based Core i5 and i7 800 series processors, and the accompanying P55 Express chipset, Intel's current flagship CPU microarchitecture--codenamed Nehalem--finally trickles its way down into the mainstream computing segment. Since Nehalem first landed on the desktop in the form of the Core i7 line of processors, it has unequivocally owned the performance segment of the market.  They are simply the fastest desktop processors currently available, bar none. But while the Core i7 was riding high, Intel still had the established Core 2 line-up to satisfy the mainstream, though meeting market demand for a refresh here as well was obviously the end game.

Along with the new Core i5 and Core i7 800 series processors and P55 Express chipset, also come a plethora of new features and changes. While the Core i5 and i7 800 series processors are based on Nehalem and share similar execution cores, with these new processors, Intel has changed the integrated memory controller configuration, brought PCI Express connectivity on-die, and revamped their Turbo Mode functionality to offer varying levels of increased performance depending on the type of application being used. These new processors also require a new socket, new coolers, and the P55 Express chipset--which is an elegant single-chip solution.

There's a lot of information to cover to fill you all in on the pertinent details regarding the Core i5 and i7 800 series processors and P55 Express chipset. So we'll dive right in. First up we have some specifications on tap, and then we'll follow up with architectural and platform details, and a full performance breakdown using a trio of P55-based motherboards. Lots to see; let's get to it...

Google 'experiment' crossbreeds Python with C++

Multi-core coding on the Go








Google has open-sourced an experimental programming language that attempts to crossbreed a dynamic web-happy language like Python with a compiled language like C++.
"There is a growing rebellion against cumbersome type systems like those of Java and C++, pushing people towards dynamically typed languages such as Python and JavaScript, [but] some fundamental concepts such as garbage collection and parallel computation are not well supported by popular systems languages," the company says.
"We believe it's worth trying again with a new language, a concurrent, garbage-collected language with fast compilation."
Dubbed Go, the new language was unveiled today via the Google Open Source blog. "Want to write a server with thousands of communicating threads? Want to spend less time reading blogs while waiting for builds? Feel like whipping up a prototype of your latest idea? Go is the way to go!"
Google says the language is type safe and memory safe, and it's specifically designed for building software that runs on multi-core machines. Systems and servers are written as lightweight processes called goroutines. "Run thousands of goroutines if you want - and say good-bye to stack overflows," Google says.
But more than anything else, Google plays up the speed of the language - at both compile time and run-time. "Typical builds feel instantaneous," the company says. "Even large binaries compile in just a few seconds. And the compiled code runs close to the speed of C. Go lets you move fast."
In a video trumpeting the new language, Googler Russ Cox shows off the Go math package, which includes about 1,000 lines of code across and about 20 files. It builds in about 20 milliseconds, he says, and he can test the package - which involves rebuilding and running - in under a second.

The project's developers include Unix founding father Ken Thompson; fellow Bell Labs Unix developer Rob Pike; and Robert Griesemer, known for his work on the Java HotSpot compiler. They call the language Go because, well, you know. "'Ogle' would be a good name for a Go debugger," the company says.

Microsoft putting Windows 7 onto USB drives -- sort of, almost

Responding to concerns about loading Windows 7 onto netbooks and other computers that don't have DVD drives, Microsoft introduced a tool to load the software onto a USB memory stick.

A netbook can then boot up from the USB stick, initiating the process of upgrading the PC to Windows 7.

The "Windows 7 USB/DVD Download Tool" is used when you buy a downloadable version of the software from Microsoft's online store. During the download process, buyers are given the option of creating a bootable USB stick or burning a DVD.

A number of hobbyist sites have been offering similar software tools for transferring Windows 7 to USB sticks, although it can take a leap of faith to download and use some of them.

In Monday's Windows 7 review I said the easiest option would be if Microsoft sold USB drives preloaded with the software. Reading between the lines of a Windows team blog entry today, it sounds like that may happen soon.

"We're working with partners now to deliver similar tools through their sites and hope to have more news to share in this regard soon," it said.
