Live from Microsoft's Windows 8 preview event at Computex 2011!


10:52AM And that's that. Let's go and see if we can't get to handle those dev machines!

10:52AM The Build conference in September will have "everything" about Windows 8.


10:51AM Evidently, Microsoft is taking a more active role in pushing the hardware for Windows 8 devices forward.

10:51AM "We have some recommendations on bezel sizes so you can easily hold the system" while also being able to use it comfortably.


10:50AM Minimum of 1366 x 768 resolution for the best Windows 8 experience. 1024 x 768 will be the absolute minimum for the new UI fanciness and 1024 x 600 will let you run Windows 8 in the classic desktop mode.


10:49AM Supporting a whole range of new sensors as well.

10:49AM UEFI engagement will help with speeding up boot times. "I've seen systems with SSDs inside them that can go from a cold boot to the Start screen in under 6 seconds."

10:48AM OEM Activation 3.0. A seamless activation experience for end users and it'll streamline things for hardware partners.


10:47AM "From day one, we started engineering these systems with a much closer integration of hardware and software than ever."

10:47AM He's pointing out that whether you're running x86 or ARM, you'll be enjoying the same apps.


10:46AM "The same app, completely cross-platform, based on the Windows 8 application development platform."

10:46AM Hardware-accelerated HTML5 shown off on the dev Kal-El tablet.

10:45AM And now a tablet with the same super-powered chip.



10:45AM Woah, a skinny laptop running NVIDIA's quad-core Kal-El chip!


10:44AM "You can build them virtually any size and shape, all being able to run Windows."


10:44AM Showing a USB stick connected to one of the dev devices and shows that it works just as it does on the desktop.


10:42AM Mike also showed us a Snapdragon system-on-chip just so we know teeny tiny these things are.

10:42AM A new mode called "always on, always connected." It'll permit for instant wake-up from sleep and keep the ARM tablets constantly connected to the web. We're also promised great battery life.





10:40AM We saw motherboards back at CES, now dev devices. These won't ever be on sale, but it shows progress.

10:40AM Qualcomm, NVIDIA and TI developer reference systems for Windows 8 on ARM.


10:39AM "Not multiple versions of Windows, just one version of Windows running on all of them."


10:39AM "With or without touhscreens, with or without keyboards, the full Windows experience."

10:39AM Windows adapts to it by launching apps in full screen instead of side by side as on the widescreen diplays.

10:38AM Now also showing Windows 8 on a tablet that doesn't have a 16:9 display resolution.


10:38AM "The Llano processor that's coming out this quarter." We already kind of knew that, but good to have confirmation, Microsoft!

10:37AM Showing an HP dv6 will AMD Llano inside. Hah!


10:37AM PageUp and PageDown buttons will allow you to move between tiles on non-touchscreen devices.

10:36AM "Windows 8 will be able to run on a wide range of machines because it will have the same system requirements or lower."


10:36AM "Windows 8 is an upgrade for the entire ecosystem of PCs."

10:36AM "How is this going to work on all the other systems?"

10:35AM 1366 x 768 resolution on that Dell system.

10:35AM You can also do a split-screen interface, where you see both the new and the old UI side by side.

10:35AM The big difference with Windows 8 is that when you get into the apps, they're all optimized for touch.



10:34AM Switching between the live-tile UI and the usual desktop is instantaneous. We're seeing some seriously impressive performance here. And it's all done on that Dell XPS proto system.



10:34AM Now he brought us back out into the familiar Windows desktop. It looks identical to the current Windows 7 desktop UI.




10:33AM There's a look at the onscreen keyboard, which is identical to the nice one in WP7. Also a split version that we saw earlier at d9.

10:32AM "A browser optimized for touch. Optimized for panning and zooming."

10:32AM "With Windows 8, we're gonna be introducing IE 10."







10:32AM "Real multitasking" demonstrated, where a video plays back while you negotiate your way around other apps. Frankly, Windows has always been able to do that, but this is indeed pretty swanky when it comes to tablets.

10:31AM The full screen experience is designed for 16:9 widescreens.


10:30AM And if you're holding a tablet, all the controls are right under your thumb.

10:30AM Woah, you can switch between apps by just dragging them in from the side.


10:29AM Swiping in from the side brings in a sub-menu that looks equivalent to the taskbar in the current Windows.

10:29AM "On day one, when Windows 8 ships, hundreds of millions of developers will already know" how to develop for it.



10:29AM Created on Windows' new application development platform. Based on HTML5, JavaScript and CSS.

10:28AM "The first thing you notice is that the apps are chromeless, they immediately take up the whole screen."

10:28AM Notifications, new tweets, new email, "it's all presented to you immediately without having to take that extra step."

10:28AM The tiles that you see on the Start screen are live. "They represent your apps, your people, your contacts, the things that you care most about."



10:27AM Ridiculously smooth scrolling.

10:27AM Log in by swiping up on the lock screen and you're right into the Start screen.

10:27AM A Dell XPS development station.

10:27AM Here comes a look at the hardware on stage.

10:26AM The devices we use to connect to the web have changed. "Thinner and lighter, resume from sleep immediately... some of them have batteries that run for weeks on end."


10:26AM Today, we're facing trends to do with immersive experiences, touchscreens, and the web.

10:25AM When Windows 7 was being designed, the trends were around ultra-portable notebooks, which is why it was made to run so efficiently.

10:25AM "Windows has continuously adapted" to new trends and development in the industry.

10:24AM Mike: "I'll begin with a little bit of background on some of the decisions behind Windows 8."



10:24AM Here comes Mike Angulo, who is responsible for Windows planning and Microsoft hardware.

10:23AM Big thanks expressed to the hardware manufacturers working with Microsoft.



10:22AM "We refer to the next version of Windows internally as Windows 8."

10:22AM "An update on the next version of Windows."





10:20AM The event will begin in one minute.


10:19AM Yes, there are some extremely skinny notbooks on show too.


10:15AM It seems we're on the brink of being shown the first Windows 8 ARM devices.

10:14AM Intel and AMD placards are joined by Qualcomm, Texas Instruments and NVIDIA!

10:10AM We're seeing tablets and monitors up on the stage, both featuring the new tile UI of Windows 8.



10:08AM And yay, the doors have opened, we're in!


9:56AM We're just about to be let into the event venue, high up in the swanky W Hotel.
Microsoft finally debuted the next version of its Windows operating system, codenamed Windows 8, at D9 earlier today, and now it's hitting up Computex over in Taipei with a partner preview event. We don't know quite what will be revealed here, but the new Win 8 UI has a touch-friendly look designed specifically to make tablet users feel more at home, so a peek at new slate hardware might not be completely out of the question. Join us after the break for all the live updates from the event.

Apple to unveil iCloud, iOS 5 on Monday, June 6


Apple to unveil iCloud Monday, June 6
Had some doubts that Apple was heading skyward? Those lingering concerns can now be put to rest. Apple has confirmed that it will be announcing iCloud on June 6th, what it's calling an "upcoming cloud services offering." That will be part of the keynote for this year's Worldwide Developers Conference, known to the cool kids as WWDC. This is, of course, where everyone has come to expect new iPhones to come to light, but this year we're thinking the focus will be more on software, and indeed Apple's event notice indicates that the big highlights will be Mac OS X Lion and the next version of its mobile operating system, iOS 5. This is a decidedly non-Apple way to announce something big like iCloud, making us wonder what other surprises Steve Jobs will have for us at the event -- yes, he'll be kicking things off. As ever you can find out as it happens here, live.

Linux vs Other Operating Systems : 7 common myths busted 89

Introduction

When it comes to operating systems people have always looked up to Windows and Mac OS X as the front-runners of the OS battle. However, due to recent efforts of the ever-growing Linux community, this scenario has changed only to accommodate Linux as a beleaguered underdog. Thanks to its escalating popularity amongst desktop users worldwide, the open source operating system has already been deemed as a serious competitor to Windows and Mac OS X . Similarly on the server side, many corporations are switching to Linux due to its reliability and speed. So then, what is it that makes Linux so special when contrasted with other OS’s namely Windows and Macs? Why are many people switching to an operating system that is not only free but is not even backed by any multi-million dollar corporation? This article answers many such questions.

Why not Windows or Macs?

Ok, let us tackle the problems with Windows and Macs first. Windows, developed by Microsoft Corporation, is the Operating System with the largest market share. However, this doesn’t make it the best when it comes to quality and consistency as it is constantly marred with problems of viruses and malware. Also, the initial investment in a Windows PC is much higher than what a consumer expects to pay. First it is the cost of the hardware itself, then the cost of the license to run Windows, then an Office program, and finally to protect it all, a decent antivirus software. In short, the license may carry an affordable price tag but the expenses finally pile up to burn a large hole in the consumer's pocket. As for computers that come with Windows pre-installed, the cost of antivirus, Office utilities and other non-free programs usually overrides the buyer's budget. Furthermore, the version of Windows provided is usually Home or Business edition, which lacks many features the Ultimate version provides.
Coming to Macintosh computers, they, unlike Microsoft, prefer to sell their software bundled with their own hardware. Apple claims that their design, feature-set and stability are much superior to any of Microsoft products; even if it comes at a very high price point. Nevertheless, Macs, despite their holier-than-thou attitude towards Windows and Linux, are far from being the perfect computers. Consumers and Microsoft employees frequently complain that Macs are significantly overpriced than a normal laptop/PC. Apple does have many quality programs for its users but most of them are highly priced and are not open source. Furthermore, Apple has gained notoriety for making closed, locked-down Mac exclusive products thus creating a walled garden of their own.
Note: The points mentioned above are not intended to offend any Windows or Mac lovers. I'm merely pointing out that Windows and Macs, contrary to popular belief and marketing claims, are far from being perfect and flawless products.

Why Linux?

After pointing out all the downsides of Windows and Macs, I come to the main point, that is, why should anyone switch to Linux. We all know that it is for geeks, don't we? Besides, how good can an OS be if it completely free and open source? Let's tackle all these questions one by one.

Myth 1: Linux is just for geeks

Linux is for everyone. While Linux based distributions like Ubuntu, Linux Mint and Fedora are developed with the non-technical user in mind, Slackware and others appeal to the more geeky ones. Believe it or not, installing Ubuntu is actually easier than a Windows installation , and using it requires no special skills.

Myth 2 : Linux can’t handle Excel, Word, Powerpoint

Linux can handle all the major file formats when it comes to documents as it comes with a powerful opensource Office suite called Openoffice.org (soon to be replaced by Libreoffice). So, apart from doing all the spreadsheets, presentations, and word processing out of the box, Linux can do tasks like publishing, image editing using only free and open source applications.

Myth 3 : Linux is free, so it sucks.

Many people think that Linux, because it is free, cannot be considered as a 'product', and thus, it may not be as good as Windows and Macs. This belief however, is completely wrong. Linux is the result of contributions by millions of users from all around the world, and it is through their incessant efforts that Linux continues to be free. Besides, what’s bad about being free anyway? After all, the best things in life are free; aren’t they?

Myth 4 : Desktops are dead, so is Linux

With the rapid emergence of smartphones, tablets and a myriad of handheld devices running powerful softwares, the popularity of desktops is slowly falling. However, this process is slow, and many have denied the fact that desktops will get replaced by devices like tablets; at least for the next 5 years. Whichever way the paradigm shifts, Linux enthusiasts won't be disappointed as almost all the next-gen gadgets being developed are already capable of running Linux. Consider for example, Android smartphones which are rapidly overtaking Apple's iphones; these devices are running on Android Operating System which is based on … yes, you guessed it right … Linux. Also when it comes to tablets, Android powered tablets have started appearing in the market ready to take on Apple's ipad. Finally, with the steady growth of Linux based netbooks, one can without any doubt, conclude that whatever happens to desktops, Linux isn't dead or dying; it is in fact, the future.

Myth 5 : But Linux can’t handle my favorite software XYZ which is windows-only.

Linux maybe not be capable of running a particular program like Photoshop, but it does have an opensource alternative with equivalent features called Gimp. Many such closed-source programs exist to which Linux provides great open source alternatives. A good way to find those is through this site which provides a list of quality alternatives to many leading applications. Furthermore, a popular software called Wine makes it possible for Linux users to run many Windows programs without any virtualization or emulation. If that too, doesn't suit the user, he or she can always try dual booting which many Linux users do.

Myth 6 : Linux can’t do gaming

Windows, unlike Linux and Macs can always boast of the thousands of games it is capable of running. However, that doesn't mean gaming is an Utopian concept to the Linux world. Many indie developers have started developing games for Linux , and of course many games that run on Windows work flawlessly on Linux thanks to softwares like Wine, PlayonLinux and Transgaming Cedega. Here’s a list of the much-awaited games for Linux in 2011. 

Myth 7 : Linux lacks support.

While Microsoft and Apple both boast of an excellent support, Linux, by default doesn't offer any professional support. To make up for the lack of support, Linux offers multiple ways of seeking help; one such way is through forums .The Linux community is very large and simply posing a question in a forum, one gets a reply within a few minutes and sometimes seconds. Don't believe me? Try asking a valid, Linux related question on linuxquestions.org and a helpful reply will come quicker than you expect. For the impatient ones, there is IRC; that is, internet relay chat, where many developers and users hang out to helping other users. If that isn't adequate, one can always buy professional support offered by Ubuntu, which comes at a fair and reasonable price.

Conclusion

Summing up, Linux in almost all aspects matches up to its closest competitors and in some areas outstrips them hands down. That said, Linux’s market share still stands at a meager 2% thanks to widespread vendor lock-ins and a general lack of awareness amongst non-technical folk. This fallacy however, is slowly being overcome only to make the software world a free and better place.

The Perfect Desktop - Ubuntu Studio 11.04

This tutorial shows how you can set up an Ubuntu Studio 11.04 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.
I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

1 Preliminary Note

To fully replace a Windows desktop, I want the Ubuntu Studio desktop to have the following software installed:

Graphics:

  • The GIMP - free software replacement for Adobe Photoshop
  • Shotwell Photo Manager - full-featured personal photo management application for the GNOME desktop
  • Google Picasa - application for organizing and editing digital photos

Internet:

  • Firefox
  • Opera
  • Chromium - Google's open-source browser
  • Flash Player 10
  • FileZilla - multithreaded FTP client
  • Thunderbird - email and news client
  • Evolution - combines e-mail, calendar, address book, and task list management functions
  • aMule - P2P file sharing application
  • Transmission BitTorrent Client - Bittorrent client
  • Vuze - Java Bittorrent client
  • Empathy IM Client - multi-platform instant messaging client
  • Skype
  • Google Earth
  • Xchat IRC - IRC client
  • Gwibber Social Client - open-source microblogging client (Twitter, Facebook, etc.)

Office:

  • LibreOffice Writer - replacement for Microsoft Word
  • LibreOffice Calc - replacement for Microsoft Excel
  • Adobe Reader
  • GnuCash - double-entry book-keeping personal finance system, similar to Quicken
  • Scribus - open source desktop publishing (DTP) application

Sound & Video:

  • Amarok - audio player
  • Audacity - free, open source, cross platform digital audio editor
  • Banshee - audio player, can encode/decode various formats and synchronize music with Apple iPods
  • MPlayer - media player (video/audio), supports WMA
  • Rhythmbox Music Player - audio player, similar to Apple's iTunes, with support for iPods
  • gtkPod - software similar to Apple's iTunes, supports iPod, iPod nano, iPod shuffle, iPod photo, and iPod mini
  • XMMS - audio player similar to Winamp
  • dvd::rip - full featured DVD copy program
  • Kino - free digital video editor
  • Sound Juicer CD Extractor - CD ripping tool, supports various audio codecs
  • VLC Media Player - media player (video/audio)
  • RealPlayer - media player (available for i386 systems only)
  • Totem - media player (video/audio)
  • Xine - media player, supports various formats; can play DVDs
  • Brasero - CD/DVD burning program
  • K3B - CD/DVD burning program
  • Multimedia Codecs

Programming:

  • KompoZer - WYSIWYG HTML editor, similar to Macromedia Dreamweaver, but not as feature-rich (yet)
  • Bluefish - text editor, suitable for many programming and markup languages
  • Quanta Plus - web development environment, including a WYSIWYG editor

Other:

  • VirtualBox OSE- lets you run your old Windows desktop as a virtual machine under your Linux desktop, so you don't have to entirely abandon Windows
  • TrueType fonts
  • Java
  • Read-/Write support for NTFS partitions
Lots of our desired applications are available in the Ubuntu repositories, and some of these applications have been contributed by the Ubuntu community.
As you might have noticed, a few applications are redundant, for example there are two CD/DVD burning applications in my list (Brasero, K3B). If you know which one you like best, you obviously don't need to install the other applications, however if you like choice, then of course you can install both. The same goes for music players like Amarok, Banshee, Rhythmbox, XMMS or browsers (Firefox, Opera, Chromium).
I will use the username falko in this tutorial. Please replace it with your own username.

2 Installing The Base System

The installation of the base system is easy as 1-2-3 because the Ubuntu Studio installer doesn't offer a lot of options to choose from, so you cannot go wrong.
Download the Ubuntu Studio iso image from http://ubuntustudio.org/downloads, burn it onto a DVD, and boot your computer from it. Select your language:

Then select Install Ubuntu Studio:

Choose your language again (?):

Then select your location:



If you've selected an uncommon combination of language and location (like English as the language and Germany as the location, as in my case), the installer might tell you that there is no locale defined for this combination; in this case you have to select the locale manually. I select en_US.UTF-8 here:

Choose a keyboard layout (you will be asked to press a few keys, and the installer will try to detect your keyboard layout based on the keys you pressed):


The installer checks the installation CD, your hardware, and configures the network with DHCP if there is a DHCP server in the network:

You can accept the default hostname or specify your own one:

Please check if the installer detected your time zone correctly. If so, select Yes, otherwise No:

Now you have to partition your hard disk. For simplicity's sake I will create one big partition (with the mount point /) and a little swap partition so I select Guided - use entire disk (of course, the partitioning is totally up to you - if you like, you can create more than just one big partition, and you can also use LVM):

Select the disk that you want to partition:

When you're finished, hit Yes when you're asked Write the changes to disks?:

Afterwards, your new partitions are being created and formatted.

Fedora 15 Boosts Linux Security with Dynamic Firewalls

As the starting point for many IT perimeter defense architectures, the firewall is a critical piece of security technology. In the upcoming, Fedora 15 Linux distribution release, a new dynamic firewall technology will help to improve the critical cornerstone technology for server and desktop users.
Fedora is a Linux community project sponsored by Red Hat (NYSE: RHT) and is set to release Fedora 15 on May 24th. Security improvements are a key focus in the Fedora 15 release with a number of innovations.
"We have better support for encrypted home directories that get mounted when you log in and that goes a long way to help people feel that their data is secure," Jared Smith, Fedora Project Leader told InternetNews.com.

"Most Linux systems use IP tables type firewalls and the problem is that if you want to make a change to the firewall, it's hard to modify on the fly without reloading the entire firewall," Smith said. "Fedora 15 is really the first mainstream operating system to have a dynamic firewall where you can add or change rules and keep the firewall up and responding while you're making changing."
Smith added that the dynamic firewall technology will still need development work, but it is available in Fedora 15 for users to start playing with to see how it works with their environments.
The dynamic firewall isn't just for inbound traffic either. It can also dynamically adjust to the needs of outbound traffic originating behind the firewall.
"One of the cool things about the dynamic firewall in Fedora 15 is that it has a dbus interface, so individual applications can communicate with the firewall," Smith said. "The apps can tell the firewall to open up a port for a period of time and then shut it back down."
                                              


                                                                         
                               

Beta des Firefox 5 mit CSS-Animationen

Nachdem die Mozilla-Entwickler zu einem ähnlichen Versionsmodell wie Google mit seinem Chrome-Browser übergegangen sind, haben sie jetzt die erste Beta des Firefox 5 vorgelegt. In vier Wochen soll bereits die Produktivversion folgen. Größte Neuerung ist die Unterstützung von CSS-Animationen, die andere Browser wie Safari schon länger bieten. Die gleichzeitig erschienene Beta des Firefox 5 für Android kann Do-Not-Track-Header senden – wie die Entwickler schreiben, "als erster mobiler Browser überhaupt".
Anzeige

Die Beta des Firefox 5 für Android erlaubt das Senden von Do-Not-Track-Headern, die vor dem Protokollieren des Surf-Verhaltens schützen sollen. Vergrößern
Bild: mozilla.com
Bei einer CSS-Animation legt der Entwickler ihre Dauer und ihren Namen in den CSS-Regeln für das betreffende HTML-Element fest. Dem mit diesem Namen kombinierten Selektor @keyframes folgen dann Regeln, die Start- und Endpunkt sowie eventuelle Zwischenstadien des Elements beschreiben. Ähnlich wie bei der Browser-Engine Webkit ist allen Attributen noch ein -mozdev- vorangestellt, um sie als nicht endgültig zu kennzeichnen. Die Beispiele auf der Mozilla-Webseite sollten zwar auch mit einem Webkit-Browser funktionieren, ein Tippfehler verhindert dies jedoch: Statt -webkit-animation-duration: slidein; müsste es -webkit-animation-name: slidein; heißen.
Wer einen Beta- oder Aurora-Browser benutzt, kann jetzt leichter zu der jeweiligen anderen Version wechseln. Die Einstellung für den Do-Not-Track-Header haben die Entwickler in "Tools/Options/Privacy" verschoben, wo sie einfacher zu finden sein soll. Mit diesem Header können Anwender Websites signalisieren, dass sie keine Speicherung ihres Surf-Verhaltens wünschen. Ob die Sites darauf reagieren, bleibt ihnen überlassen.
Weitere Änderungen betreffen unter anderem eine Beschleunigung des JSON-Parser und die Unterstützung der click-Methode für alle HTML-Elemente. Letzteres ist in HTML5 vorgesehen. Die Release-Notes führen alle Änderungen auf. Eine Modifikation betrifft unter Umständen Autoren von Erweiterungen: Die Eigenschaft navigator.language enthält nun denselben Wert wie der HTTP-Header Accept-Language. Bislang konnten sich beide Einträge unterscheiden, wobei die Property die Sprache des Browser-GUI bestimmte und der Header die bevorzugte Lokalisierung angezeigter Webseiten. (ck)

How-to: run Chrome OS as a virtual machine

Itching for some Chrome OS? Well, we all are, but you might be a bit disappointed at the fact that while Google has open-sourced its progress on the OS so far, the version that is currently available for download seems eons behind what Google showed off at its event yesterday. Still, if you just have to see it for yourself, the good news is that it's a total breeze to get a virtual machine running. We used a VMWare image that was packaged up by the kind folks at gdgt, and set it up with VMWare Fusion running on a recent model MacBook Pro. Your mileage may vary depending on your particular setup (there's also an image available for the free, cross-platform VirtualBox software), but the principles should remain the same. Check it out on video after the break.
