Google’s chrome OS launch soon

Google’s Chrome OS project, first announced in July, will become available for download within a week, we’ve heard from a reliable source. Google previously said to expect an early version of the OS in the fall.

What can we expect? Driver support will likely be a weak point. We’ve heard at various times that Google has a legion of engineers working on the not so glamorous task of building hardware drivers. And we’ve also heard conflicting rumors that Google is mostly relying on hardware manufacturers to create those drivers. Whatever the truth, and it’s likely in between, having a robust set of functioning drivers is extremely important to Chrome OS’s success. People will want to download this to whatever computer they use and have it just work.

We expect Google will be careful with messaging around the launch, and endorse a small set of devices for installation. EEE PC netbooks, for example, may be one set of devices that Google will say are ready to use Chrome OS. There will likely be others as well, but don’t expect to be able to install it on whatever laptop or desktop machine you have from day one. Google has previously said they are working with Acer, Adobe, ASUS, Freescale, Hewlett-Packard, Lenovo, Qualcomm, Texas Instruments, and Toshiba on the project.

We’ve seen convincing and not so convincing screenshots of Chrome OS over the last several months. The good news is the speculation is about to end, and you can try it out yourself. If you have one of the supported devices, that is.



Windows 7 zero day exploit

A security researcher has said there is a zero-day vulnerability affecting Windows 7 and Vista.

The flaw in Windows 7 could allow an attack which would cause a critical system error, or “Blue Screen of Death”, according to researcher Laurent Gaffie.

Gaffie wrote in his blog that the flaw lies in a Server Message Block 2 (SMB2) driver.

“SRV2.SYS fails to handle malformed SMB headers for the NEGOTIATE PROTOCOL REQUEST functionality,” wrote Gaffie in a blog post on Monday.

Gaffie said he had contacted Microsoft. Comments on his blog by other users said that the flaw could lead not only to denial of service, but could also lead to remote code execution.

Computer security publication ‘The H’ wrote on Tuesday that its German sister publication had tested the proof-of-concept code, and that while the exploit had caused a reboot on Vista, the exploit had not worked on Windows 7.

Metasploit creator HD Moore said in a tweet on Tuesday that an SMB bug appeared to have been introduced into Vista SP1. Coder Josh Goebel said in a blog post that he had added the exploit code to Metasploit.

Microsoft had not responded to a request for comment at the time of writing.

Windows 7 fishy secret

As Microsoft has given green light to the public downloads of Windows 7 Beta 1 Build 7000, millions of testers will be greeted by the new default wallpapers of the operating system, featuring none other than the Siamese fighting fish. In fact, Windows 7 has been offering users a chance to have the creature, a member of the Betta splendens species, as their background since before Christmas 2008, when Build 7000 was initially leaked. Microsoft’s reason for choosing the Siamese fighting fish for Windows 7 was rather simple. The wallpaper is included only in the Beta version of Windows 7, and not in the previous three milestone developments, because this very popular freshwater fish is actually known as betta.

There is no telling, at this point in time, whether the Redmond company will continue to feature the Windows 7 betta fish wallpaper into the operating system moving forward to the next development milestone, or if the specimen will end up out of water. Should users expect an RC (release candidate) fish next? Or maybe even a gold fish for the RTM (gold) edition of Windows 7?

The betta fish featured in Windows 7 Beta on the default background is native of Thailand. However, Microsoft has chosen a specific variety of betta. Fact is that the wild and “plain vanilla” bettas are not much to look at. Just brown with shades of green and with short fins, the natural betta fish would never have been chosen to complement the Windows 7 Beta 1 default wallpaper. Nevertheless, the process of selective breeding has produced Betta splendens fish with a wide range of colors, including the blue and red, as the specimen on the Windows 7 background.

Fact is that, with the inclusion of the selectively bred betta in Windows 7 Beta, Microsoft is hinting that the previous Milestone releases of the platform were just the native versions of the fish. Yet, at the same time, Milestone 1, M2 and M3 of Windows 7 were much more Windows Vista than the next iteration of the Windows client. The inclusion of the betta fish in Windows 7 Betta is accompanying the evolution process from Vista to Win 7, as Microsoft is doing a tad of “selective breeding” of its own.

windows 7 secret tricks

Lately I installed windows 7 on my xps 1210 and its awesome. I had been discovering small tricks in win 7 and then I stumbled upon to this mega tricks list of the OS on msdn blogs.


  1. Windows Management. By now, you’ve probably seen that Windows 7 does a lot to make window management easier: you can “dock” a window to the left or right half of the screen by simply dragging it to the edge; similarly, you can drag the window to the top of the screen to maximize it, and double-click the window top / bottom border to maximize it vertically with the same horizontal width. What you might not know is that all these actions are also available with keyboard shortcuts:
    • Win+Left Arrow and Win+Right Arrow dock;
    • Win+Up Arrow and Win+Down Arrow maximizes and restores / minimizes;
    • Win+Shift+Up Arrow and Win+Shift+Down Arrow maximizes and restores the vertical size.

    This side-by-side docking feature is particularly invaluable on widescreen monitors – it makes the old Windows way of shift-clicking on two items in the taskbar and then using the context menu to arrange them feel really painful.

  2. Display Projection. Had enough of messing around with weird and wonderful OEM display driver utilities to get your notebook display onto an external projector? In that case, you’ll be pleased to know that projection is really quick and simple with Windows 7. Just hit Win+P, and you’ll be rewarded by the following pop-up window:
    The Win+P Projector Settings window allows you to quickly switch display settings.
    Use the arrow keys (or keep hitting Win+P) to switch to “clone”, “extend” or “external only” display settings. You can also access the application as displayswitch.exe.If you want broader control over presentation settings, you can also press Win+X to open the Windows Mobility Center, which allows you to turn on a presentation “mode” that switches IM clients to do not disturb, disables screensavers, sets a neutral wallpaper etc. (Note that this feature is also available in Windows Vista.)
  3. Cut Out The Clutter. Working on a document in a window and want to get rid of all the extraneous background noise? Simply hit Win+Home to minimize all the non-active background windows, keeping the window you’re using in its current position. When you’re ready, simply press Win+Home again to restore the background windows to their original locations.
  4. Multi-Monitor Windows Management. The earlier tip on window management showed how you can dock windows within a monitor. One refinement of those shortcuts is that you can use Win+Shift+Left Arrow and Win+Shift+Right Arrow to move windows from one monitor to another – keeping them in the same relative location to the monitor’s top-left origin.
  5. Command Junkies Only. One of the most popular power toys in Windows XP was “Open Command Prompt Here”, which enabled you to use the graphical shell to browse around the file system and then use the context menu to open a command prompt at the current working directory. In Windows 7 (and in Windows Vista, incidentally – although not many folk knew about it), you can simply hold the Shift key down while selecting the context menu to get exactly the same effect. If the current working directory is a network location, it will automatically map a drive letter for you.
  6. It’s a Global Village. If you’ve tried to change your desktop wallpaper, you’ve probably noticed that there’s a set of wallpapers there that match the locale you selected when you installed Windows. (If you picked US, you’ll see beautiful views of Crater Lake in Oregon, the Arches National Park, a beach in Hawai’i, etc.) In fact, there are several sets of themed wallpapers installed based on the language you choose, but the others are in a hidden directory. If you’re feeling in an international mood, simply browse to C:\Windows\Globalization\MCT and you’ll see a series of pictures under the Wallpaper directory for each country. Just double-click on the theme file in the Theme directory to display a rotation through all the pictures for that country. (Note that some countries contain a generic set of placeholder art for now.)
  7. The Black Box Recorder. Every developer wishes there was a way that an end-users could quickly and simply record a repro for the problem that they’re running into that is unique to their machine. Windows 7 comes to the rescue! Part of the in-built diagnostic tools that we use internally to send feedback on the product, the Problem Steps Recorder provides a simple screen capture tool that enables you to record a series of actions. Once you hit “record”, it tracks your mouse and keyboard and captures screenshots with any comments you choose to associate alongside them. Once you stop recording, it saves the whole thing to a ZIP file, containing an HTML-based “slide show” of the steps. It’s a really neat little tool and I can’t wait for it to become ubiquitous on every desktop! The program is called psr.exe; you can also search for it from Control Panel under “Record steps to reproduce a problem”.
    The Problem Steps Recorder provides an easy way for users to record a problem repro for later diagnosis.

The Go Web site ( explains the rationale behind creating Go, mostly citing the change of the computer landscape that’s occurred over the past decade or so that’s seen very few (if any) major systems languages spring up: more powerful PCs, many of which use multicore processors; increased dependency management in software that’s not reflected in the “header files” of C-based languages; the growing desire for dynamically typed languages (such as Python and JavaScript) instead of type systems such as Java and C++); and the poor support for concepts such as garbage collection and parallel computation.

Mac OS evolution


Witness the evolution through time of Macintosh’s operating system, Mac OS. See where it all began, from System 1.0 (1984) to Mac OS X 10.5 (2007).

System 1.0 (January 1984)



The first version of the Mac OS is easily distinguished between other operating systems from the same period because it does not use a command line interface; it was one of the first operating systems to use an entirely graphical user interface. Additional to the system kernel is the Finder, an application used for file management, which also displays the Desktop.

These releases could only run one application at a time, though special application shells such as Switcher could work around this to some extent. Systems 1.0, 1.1, and 2.0 used a flat file system with only one kludged level of folders, called Macintosh File System (MFS); its support for folders (subdirectories) was incomplete. System 2.1 (Finder 5.0) introduced the HFS (Hierarchical File System) which had real directories. System 3.0 was introduced with the Mac Plus, adding support for several new technologies including SCSI and AppleTalk, and introducing Trash “bulging”, i.e., when the Trash contained files, it would gain a bulged appearance. System 4.0 came with the Mac SE and Macintosh II.

The System series included the following versions:

  • System 1.0, Finder 1.0 (January 1984)
  • System 1.1, Finder 1.1g (May 1984)
  • System 2.0, Finder 4.1 (April 1985)
  • System 2.1, Finder 5.0 (September 1985)
  • System 3.0, Finder 5.1 (January 1986)
  • System 3.2, Finder 5.3 (June 1986)
  • System 3.3, Finder 5.4 (January 1987)
  • System 3.4, Finder 6.1
  • System 4.0, Finder 5.4 (March 1987)
  • System 4.1, Finder 5.5 (April 1987)

System Software 5 (October 1987)


System Software 5 (also referred to as simply System 5) added MultiFinder, an extension which let the system run several programs at once. The system used a co-operative multitasking model, meaning that time was given to the background applications only when the running application yielded control. A clever change in system functions that applications were already calling to handle events made many existing applications share time automatically. Users could also choose to not use MultiFinder, and thus stick with using a single application at a time as in previous releases of the system software.

System Software 5 was also the first Macintosh operating system to be given a unified “Macintosh System Software” version number, as opposed to the numbers used for the System and Finder files.

The System Software 5 series included the following versions:

  • System Software 5.0 (System 4.2, Finder 6.0, MultiFinder 1.0)
  • System Software 5.1 (System 4.3, Finder 6.0, MultiFinder 1.0)

System Software 6 (September 1988)


System Software 6 (also referred to as simply System 6) was a consolidation release of the Mac OS, producing a complete, stable, and long-lasting operating system.

The System Software 6 series included the following versions:

  • System Software 6.0 (System 4.4, Finder 6.1, MultiFinder 1.1 — the version numbers of the System and MultiFinder files were changed to 6.0 just before the public release)
  • System Software 6.0.1
  • System Software 6.0.2
  • System Software 6.0.3
  • System Software 6.0.4
  • System Software 6.0.5
  • System Software 6.0.6 (only released as an embedded part of the ROM of the Macintosh Classic)
  • System Software 6.0.7
  • System Software 6.0.8 (identical to System 6.0.7, but configured with System 7.0 printing software for printer sharing with System 7)
  • System Software 6.0.8L (only for Macintosh Classic, Classic II, PowerBook 100, Macintosh LC, LC II)

System 7 (May 1991)


On May 13, 1991 System 7 was released. It was the second major upgrade to the Mac OS, adding a significant user interface overhaul, new applications, stability improvements and many new features.

The most significant feature of System 7 was probably virtual memory support, which previously had only been available as a third-party add-on. Accompanying this was a move to 32-bit memory addressing, necessary for the ever-increasing amounts of RAM available. Earlier versions of Mac OS had used the lower 24 bits for addressing, and the upper 8 bits for flags. This had been an effective solution for earlier Macintosh models with very limited amounts of RAM, but it became a liability later. Apple described code that assumed the 24 + 8-bit addressing as being “not 32-bit clean”, and most such applications would crash when 32-bit addressing was enabled by the user.

One notable System 7 feature was the built-in co-operative multitasking. In System Software 6, this function was optional through the MultiFinder. System 7 also introduced aliases, similar to shortcuts that were introduced in later versions of Microsoft Windows. System extensions were enhanced, by being moved to their own subfolder; a subfolder in the System Folder was also created for the control panels. In System 7.5, Apple included the Extensions Manager, a previously third-party program which simplified the process of enabling and disabling extensions.

Systems 7.1 and 7.5 introduced a large number of “high level” additions, considered by some to be less well thought-out than they could have been. Some of the most confusing were the reliance on countless System Enablers to support new hardware, and various System update extensions with inconsistent version numbering schemes. Overall stability and performance also gradually worsened during this period, which introduced PowerPC support and 68K emulation.

Stability returned with Mac OS 7.6, which dropped the “System” moniker as a more-trademarkable name was needed in order to license the OS to the growing market of third-party Macintosh clone manufacturers.

The System 7 series included the following versions:

  • System 7.0 (released in late 1991; integrated MultiFinder always enabled)
  • System 7.0.1 (introduced with LC II and Quadra series)
  • System 7 Tuner (update for both 7.0 and 7.0.1)
  • System 7.1
  • System 7.1 Pro (version 7.1.1, combined with PowerTalk, Speech Manager & Macintalk, Thread Manager)
  • System 7.1.2 (first version for Macs equipped with a PowerPC processor)
  • System 7.1.2 (only for Performa/LC/Quadra 630 series, very quickly replaced by 7.5)
  • System 7.5
  • System 7.5.1 (System 7.5 Update 1.0 — the first Macintosh operating system to call itself “Mac OS”)
  • System 7.5.2 (first version for Power Macs that use PCI expansion cards, usable only on these Power Macs and PowerBooks 5300 and Duo 2300)
  • System 7.5.3 (System 7.5 Update 2.0)
  • System 7.5.3L (only for Mac clones)
  • System 7.5.3 Revision 2
  • System 7.5.3 Revision 2.1 (only for Performa 6400/180 and 6400/120)
  • System 7.5.4, never released
  • System 7.5.5
  • Mac OS 7.6 (name formally changed because of the experimental clone program, although System 7.5.1 and later used the “Mac OS” name on the splash screen)
  • Mac OS 7.6.1

Mac OS 8 (July 1997)


Mac OS 8 was released on July 26, 1997, shortly after Steve Jobs returned to the company. It was mainly released to keep the Mac OS moving forward during a difficult time for Apple. Initially planned as Mac OS 7.7, it was renumbered “8″ to exploit a legal loophole to accomplish Jobs’ goal of terminating third-party manufacturers’ licenses to System 7 and shutting down the Macintosh clone market.[citation needed] 8.0 added a number of features from the stillborn Copland project, while leaving the underlying operating system unchanged. A multi-threaded Finder was included, enabling better multi-tasking. The GUI was changed in appearance to a new shaded greyscale look called Platinum, and the ability to change the appearance themes (also known as skins) was added with a new control panel. This capability was provided by a new “appearance” API layer within the OS, one of the few significant changes.

Apple sold 1.2 million copies of Mac OS 8 in its first two weeks of availability and 3 million within six months. Mac OS 8.1 saw the introduction of an updated version of the Hierarchical File System called HFS Plus , which fixed many of the limitations of the earlier system (HFS Plus continues to be used in Mac OS X). There were some other interface changes such as separating network features from printing (the venerable, and rather odd Chooser was at last headed for retirement), and some improvements to application switching. However, in underlying technical respects, Mac OS 8 was not very different from System 7.

The Mac OS 8 series included the following versions:

  • Mac OS 8.0
  • Mac OS 8.1 (last version to run on either a 68K or PowerPC processor, added support for USB on the Bondi iMac, added support for HFS+)
  • Mac OS 8.5 (first version to run only on a PowerPC processor, added built-in support for Firewire on the PowerMac G3)
  • Mac OS 8.5.1
  • Mac OS 8.6 (included a new nanokernel for improved performance and Multiprocessing Services 2.0 support, added support for the PowerPC G4 processor)

Mac OS 9 (October 1999)



Mac OS 9 was released on October 23, 1999. It was generally a steady evolution from Mac OS 8. Early development releases of Mac OS 9 were numbered 8.7. MacOS 9 added improved support for AirPort wireless networking. It introduced an early implementation of multi-user support (though not considered a true multi-user operating system by modern standards). An improved find-sherlock engine with several new search plug-ins. Mac OS 9 also provided a much improved memory implementation and management. AppleScript was improved to allow TCP/IP and networking control. Mac OS 9 also made the first use of the centralized Apple Software Update to find and install OS and hardware updates. Some other resplendent and unique features included its on-the-fly file encryption software with code signing and Keychain technologies, Remote Networking and File Server packages and much improved list of USB drivers.

OS 9 also added some transitional technologies to help application developers adopt some OS X features before the introduction of the new OS to the public, again easing the transition. These included new APIs for the file system, and the bundling of the Carbon library that apps could link against instead of the traditional API libraries — apps that were adapted to do this can be run natively on OS X as well. Other changes were made in OS 9 to allow it to be booted in the “classic environment” within OS X. This is a compatibility layer in OS X (in fact an OS X application, known in developer circles as “the blue box”) that runs a complete Mac OS 9 operating system, so allowing applications that have not been ported to Carbon to run on Mac OS X. This is reasonably seamless, though “classic” applications retain their original OS 8/9 appearance and do not gain the OS X “Aqua” appearance.

The Mac OS 9 series included the following versions:

  • Mac OS 9.0
  • Mac OS 9.0.2
  • Mac OS 9.0.3
  • Mac OS 9.0.4
  • Mac OS 9.1
  • Mac OS 9.2
  • Mac OS 9.2.1
  • Mac OS 9.2.2

Mac OS X (March 2001)



Mac OS X is the newest of Apple Computer’s Mac OS line of operating systems. Although it is officially designated as simply “version 10″ of the Mac OS, it has a history largely independent of the earlier Mac OS releases.

The Mac OS X series include the following versions:

  • Mac OS X Public Beta “Kodiak”
  • Mac OS X v10.0 “Cheetah”
  • Mac OS X v10.1 “Puma”
  • Mac OS X v10.2 “Jaguar”
  • Mac OS X v10.3 “Panther”
  • Mac OS X v10.4 “Tiger”
  • Mac OS X v10.5 “Leopard”
  • Mac OS X v 10.6 “Snow leopard”
