Microsoft details battery saving and touch features on Windows 8 RT, device sizes

Microsoft is gearing up to launch Windows 8, a version that marks a significant departure from previous incarnations in that it supports ARM processors. The Redmond-based company is quite excited about what it has achieved with Windows 8 RT (that’s what the ARM version is called) and the kind of hardware it and its OEM partners have designed.

One of the biggest advantages of ARM over Intel or AMD made x86 processors is energy efficiency. Windows 8 RT was designed to reduce power usage to capitalize on that, but also allow for smaller batteries, which in turn means thinner and lighter gadgets.

One of the power-saving features is Connected standby, which is the answer to the dilemma of choosing between putting your computer to sleep or keeping it on to receive notifications.

Connected standby is like sleep mode but Windows keeps an active connection and checks for new events. It uses a lot less energy than just keeping the computer on. Here’s some battery life figures of a Windows 8 RT device in playing an HD video and in active standby (I wish they included regular standby too, to see just how much energy is saved).

Scenario	Early production range
HD Video Playback	8 hours to 13 hours of scenario run time
Connected Standby	320 hours to 409 hours of scenario run time

Batteries for RT devices will range from 25Wh to 42Wh, while screen sizes will be going between 10.1″ and 11.6″ for laptops and tablets. Here’s what you can expect in terms of overall size and weight of the devices.

System characteristics	Measurement range
Weight (g)	520g to 1200g
Length (mm)	263mm to 298mm
Width (mm)	168.5mm to 204mm
Height (mm)	8.35mm to 15.6mm

A tablet that’s 8.35mm thick and weighs 520g sounds pretty good, but the 15.6mm, 1200g device seems a bit bulky even if it’s for a laptop. After all, there are laptops with x86 CPUs capable of running classic Windows (which means all Windows 7 apps) that are this big (for a 13″ screen too).

Anyway, Microsoft’s desire to reduce power usage had some interesting consequences. They combined all chips responsible for touch interaction, which reduced power usage, but the new design also has some really cool features.

One of them is 100 Hz finger tracking. Here’s a video from Microsoft Research that shows just what kind of difference a high frequency tracking makes (100Hz is at the 10ms part of the video).

Also, check out these finger gestures that Windows 8 supports.

Single-finger slide	Single/two-finger tap, double tap	Two-finger slide
Mouse cursor manipulation	Primary/secondary button click, double-click at cursor location	Horizontal or vertical scroll (mouse wheel)

Two-finger pinch	Swipe in from the right edge	Swipe down from the top edge	Swipe in from the left edge
Zoom (Ctrl + mouse wheel)	Toggle the charms (Windows logo key + C)	Toggle the app commands (Windows logo key + Z)	Switch to last app (Windows logo key + Ctrl + Backspace)

Archos is launching a new line of tablets, Gen10 XS, starting mid-September, including a 10-inch Android tablet that boasts a removable keyboard. The Archos 101 XS is the first tablet in the French electronics brand’s new line. Thinner than the current iPad at 8mm (against 9.4mm for the apple device),it’s weight 600gm.

Its 10.1 inch screen boasts a resolution of 1280 x 800, and the device runs on a 1.5GHz processor, with 1Gb of RAM and 16Gb of Flash memory (which can be extended with MicroSD cards). It is WiFi and Bluetooth enabled, but there will be no 3G version.

 

The tablet will be shipped with a removable magnetic keyboard that will double as a protective case and kickstand, similar to the keyboards for the Transformers line of Asus tablets and the upcoming Microsoft Surface.

The 101 XS can also connect to a TV via HDMI, and can be operated remotely using an Android phone, via a special app to download from Google Play.

The Gen10 XS tablets ship with Archos Media Center apps, allowing the reading of most audio and video formats and compatible with Full HD 1080p files.

The tablet will be available mid-September for €379. Two other models, 97 XS and 80 XS, will be added to the line before the end of the year.

 

 

 

 

The difference between IP4 and IP6 Addressing.

The most obvious difference between the two protocols is the length of their source and destination addresses. The whole point of making the switch to IPv6 is to compensate for a global shortage of IP addresses. It only makes sense that the IPv6 protocol has a larger address space than the IPv4 protocol does.

The IPv4 protocol uses a 32-bit source and destination address. These addresses are typically represented as a series of four octets. As I’m sure you know, a typical IPv4 address looks something like this: 192.168.0.1.

In contrast, an IPv6 address is 128 bits in length. This allows for a total of 3.4×10³⁸ (or 340,000,000,000,000,000,000,000,000,000,000,000,000)  addresses. There are several different ways of representing an IPv6 address. An IPv6 address is normally written as eight groups of four hexadecimal digits, each separated by colons. For example, an IPv6 address looks like this: 2001:0f68:0000:0000:0000:0000:1986:69af.

What Do Those 404 and Other HTTP Return Codes Mean?

404 (Not Found). If you happen to mistype a URL or enter an old one that no longer exists this is the error you will likely see. The condition may be temporary or permanent but this information is rarely provided. Sometimes code 403 is sent in place of 404.

What is scan code.

In the keyboard are little switches. When you press a key one of the switches is activated and when you release that key the switch is activated again. The keyboard makes note of these happenings and stores them in a small buffer (memory area) in the keyboard while it notifies the computer that something has happened at the keyboard (an interrupt). The computer, once notified of keyboard activity reads the buffer and takes the necessary action.

Each key on the keyboard has its own code that it sends when pressed and when released; this is called its scan code. When listing scan codes here we’ll list the “press” scan code. The “release” scan code is that number plus 128 (80 hex).

While the original scan code specification allowed for a single number, newer keyboards with the movement keys repeated in the center of the keyboard forced a change and those keys carry a two-number scan code with the first number always being hex E0 (so programs reading scan codes first test for the E0 character; if not found process the code directly, if found, process the next code as one of the center movement keys).

At first blush the release code may seem redundant but when you think about how often you might press and hold the shift, control, or alt keys down while typing something else it becomes clear why it’s needed.

That said, here are the various scan codes originally defined by IBM (you can see from the layout these were defined for the very first keyboard)…

• hex 01 = Escape key

Intel Reportedly Shipping Graphics Free Core i5 3350P Ivy Bridge CPU in Q3

Intel and Advanced Micro Devices (AMD) these days are all about combining CPU and GPU functions onto single slices of silicon, but is there still a market for GPU-less processors? Sure there is.

If  you’re really interested in is the CPU portion of a processor anyway. To serve those customers, Intel is said to be readying the release of its Core i5 3350P processor, which is an Ivy Bridge chip without graphics.

The Core i5 3350P part reportedly sports a 3.1GHz base clockspeed and ramps up to 3.3GHz via Turbo. It’s a quad-core chip with four threads (no HyperThreading, unfortunately), 6MB of cache, and a 69W TDP.

See How Ubuntu Linux Will Be Improved

Friday, August 24, 2012:  What makes Ubuntu Linux 12.04 all the more important is that it is not only one of the most popular Linux distros but is also Canonical’s LTS (Long Term Support) version. This basically means that besides regular improvements, this distro will get some serious updates every now and then. The latest one is here.    While there are not any major changes but the first update, Ubuntu 12.04.1, will definitely be a little different. According to Canonical, this new update will bring “fixes and enhancements translate into a rock-solid, thoroughly tested upgrade path for any enterprise running Ubuntu 10.04, the last LTS release. Users on 10.04 LTS will then receive their first system notifications encouraging them to upgrade to the new LTS release. Consequently, we expect an even bigger shift among enterprise users than we experienced when it was first made available, back in April. Enterprise users can now be completely confident that the upgrade will be fast and free from disruption.” Moreover, with this, Canonical has added support for Calxeda SoCs. The developers recently said that they are big believers in ARM servers finding a role in the datacenter. What’s more. Ubuntu is also continuing to strengthen its support for OpenStack as its preferred cloud infrastructure. With 12.04.1, Ubuntu is introducing Ubuntu Cloud Archive, This is an OpenStack online software repository. With it, administrators can download the latest versions of OpenStack without having to migrate away from their chosen LTS release, states ZDNet report.  Users can even download Folsom, which is the forthcoming release of OpenStack, slated for 27 September. As for the desktop, Canonical claims “a raft of bug fixes and security updates combine with five years of guaranteed updates and the option of commercial support to make this release an extremely attractive alternative to Windows.” All the security updates can be checked on Ubuntu Security Notice list at      http://www.ubuntu.com/usn/precise/
