The Alternatives to Windows 8

Windows 8 is unique in that it is the first version of Microsoft’s mighty operating system that faces serious and stiff competition from its rivals.  For the first time there are not just one but a great many serious contenders for the role of your desktop OS.  So with so many people wary about the changes that Microsoft are bringing forth I thought I’d take a look at the alternatives, see how they might fit with your Windows world, and examine just how realistic a switch away from Windows this year can actually be.

Windows 7

The obvious place to start is with Windows 8′s predecessor, Windows 7.  One thing is certain, that this operating system will be hugely popular right up until support ends for it in January 2020 and possibly even beyond as it wouldn’t be without precedent for Microsoft to extend the support life for a version of Windows.  Windows 7 could be considered the ‘ultimate’ version of the desktop OS, not just because it’s the last true desktop OS from Microsoft, but because of its reputation for reliability, compatibility, stability and security.  There is also XP Mode to run any older Windows software that won’t run natively, but with support ending for XP in April 2014, it would be unwise to use any XP software after this time that requires Internet access, and many including Microsoft and security researchers would advise not using it at all after this time.  Sticking with Windows 7 is probably the best solution in many ways.  It will still be on sale and being shipped with new PCs until the autumn of this year and many will consider it the operating system to use going forward.

Windows Vista

Few people would now consider Windows Vista as a viable alternative to Windows 7 or Windows 8.  Notoriously slow, especially on older hardware, and with software compatibility that was largely broken, almost all Vista users have either upgraded to Windows 7 already or plan to do so as soon as possible.

Windows XP

Despite the popularity and compatibility of Windows 7, it’s Windows XP that has won hearts and minds in the way no other Microsoft operating system ever has.  This comes despite some huge security issues that have plagued the platform and its default web browser Internet Explorer 6.  This operating system is already out of mainstream support, so no more service packs and updates are being issued, and extended support for security and stability fixes ends in less than two years, before the launch of Windows 9.  A lack of suport for new technologies including USB3 and Thunderbolt also count against this OS, unless you are able to get specific third-party drivers.  Anybody sticking with Windows XP will need to have a very good understanding of the security risks involved in doing so, this really isn’t a strong contender for your OS choice for the next few years.

OS X

Apple’s desktop operating system has a great many strengths, but a few major weaknesses as well.  Those strengths involve being one of the most stable and secure operating systems the world has ever seen.  It’s eminently usable too with gesture control that Windows 7 simply can’t match and a software base every bit as strong as that for Windows.  It’s not going anywhere either.  On the minus side there are still questions about how Apple are set to integrate their iOS tablet features into the desktop, effectively doing what Microsoft are doing with Windows 8 but probably to a slightly lesser degree.  Moving to OS X would also not just require buying a new and sometimes expensive computer (or even computers) but unless you were going to run Windows 7 or Windows 8 in Boot Camp or the Parallel’s virtual machine, you would have to re-purchase all your software as well, as very little software these days comes with both PC and Mac licensing.

Ubuntu

Three years ago GNU/Linux was still the rank outsider in the desktop OS world, but times have changed with Canonical turning their Ubuntu OS into an operating system every bit as polished and usable as OS X or Windows 7.  The best part is that this operating system is free and, with version 12.1 now comes with long-term support, meaning it’s no longer essential to upgrade your operating system every few months.  On the downside, software support, especially for the major apps is still lacking with traditional Linux apps lagging behind their OS X and Windows alternatives.  Ubuntu’s new HUD (Head up Display) for finding menu items in software might not be to everyone’s tastes either.  This feature can be switched off and traditional drop down menus reinstated, but Ubuntu still needs that all important software support to compete on a level playing field.

ReactOS

Currently in alpha, this Russian organised Windows NT/XP clone promises to be binary compatible with Windows and support every piece of hardware and software that works with Windows XP.  It’s a bold claim that so far seems to be panning out.  It should be complete and bedded-in by the time Windows XP support ends so it could be a viable alternative.  On the down side, Microsoft has a way of aggresssively going after any “Windows Clone” and having already shut down Lindows a few years ago they will soon have their guns trained on ReactOS, no matter how well the developers might be covering themselves in terms of copyright.  There is also the fact that ReactOS has been in an alpha stage now for an extremely long time, and frankly may never be completely finished.

iOs, Android, QNX

Do you actually need a full desktop operating system any more?  This is an interesting question as the majority of tasks we perform on our PCs can now be done equally well on a tablet running Apple’s iOS, Google Android or RIM’s QNX.  These tasks, including email and web browsing are actually pleasurable on modern tablet operating systems and this situation is only set to improve.  The burgeoning app stores, and the quality of those apps is improving every day too with companies like Adobe showing how advanced photo editing, another of our major tasks, can be made simple and pleasurable on a tablet.

Here the problem is storage and file management.  With a tablet you’re restricted to storing your files mainly in cloud services and in order to get those files on the tablet in the first place, or indeed into the cloud, you need to synchronise with a desktop computer.  We can fully expect these devices to become more independent over time, and perhaps even support external hard disks and USB pen drives.  Unless and until this happens though these tablets (and I’m obviously excluding Windows 8 tablets from the list) just aren’t quite ready to handle our ever expanding collections of music, videos, files and photographs.

Summary

So this is my own take on the alternatives to Windows 8 and how effective and realistic a move to each one might be.  You will probably have your own ideas on what would make a good alternative and why.  You might be just sticking with XP despite the security concerns, or sticking with Windows 7.  You may even decide that now is the time to get rid of your desktop PC altogether and move solely to a tablet.  Perhaps your music is already stored in the cloud or you use a service like spotify, and maybe your new digital camera can upload your files directly to Picassa or another cloud service for you.  Why not tell us your thoughts in the comments.

ReactOS, the Windows XP Alternative

While we wait for the Windows 8 beta to be released at the end of the month questions are looming over what will happen with legacy software support and how we’ll run our older, but still useful and trustworthy, software in the future.  Windows 7 Professional, Enterprise and Ultimate can run the free XP Mode, a fully-licenced copy of XP Professional running in a specially modified virtual machine.  Here we can continue to use our older apps, as I do so myself, safe in the knowledge that they’ll plug right into our Windows 7 Start Menu and appear on the desktop without having to have the XP desktop open as well.

But there’s a problem looming, and it’s a biggie.  In April 2014, just over two years from now, all support for Windows XP will end.  This means that there will be no more security patches and fixes… ever!  Now if you use only XP apps that don’t connect to the Internet this won’t be a problem, but Windows 8 won’t support XP Mode at all because of this end of support and even though the operating system will include its own virtual machine, Hyper-V, we don’t know yet if plugging applications into the new Start Screen, or onto the Windows 8 Taskbar will be possible.

Then there’s the simple fact that, no matter what new IT Pro and business features the beta of Windows 8 will bring, some people will simply decide that its not for them.  Many businesses skip Windows releases after all and many are only just deploying Windows 7.  But for people who are still on XP and don’t want to move to either Windows 7 or Windows 8 because of software and hardware compatibility what will the alternative be after the April 2014 deadline?

The answer could come in the form of ReactOS, a Russian-developed Windows NT/XP clone.  On their website they describe the product as…

“ReactOS is a free and open-source operating system based on the Windows NT  architecture, providing support for existing applications and drivers, and an alternative to the current dominant consumer and server operating systems.”

This operating system, still in the alpha stage, promises to be binary compatible with all Windows XP hardware and software.  Rather than being a GNU/Linux OS with the Windows WINE emulator over the top, this is a complete Windows-clone OS.  When it’s finished the makers say that anything you can currently do with Windows XP you will be able to do with ReactOS.

As a product that’s new and currently in development there will be ongoing support too with patches and upgrades, and presumably they will make modifications to the underlying security system to rectify Windows XP’s inherent flaws.

Surely then Microsoft would go after ReactOS as aggressively as they have with other Windows clones such as Lindows?  ReactOS have several answers to that, one of which is…

“Most people  think of ‘NT’ as ‘WinNT 4′, while in reality the term NT refers to the NT series, which ranges from version 3 over NT5 (2000, XP, 2003) to NT6 (Vista, 2008 and 7). The NT architecture was designed by a team lead by David Cutler, a former  lead developer of VMS. It took them more than 4 years to combine the best of  UNIX, VMS and OS/2 and create the NT architecture.”

There is also the fact that Russia, the home of the OS, doesn’t observe International copyright law and so nobody can touch them… yet!  On December 16th 2011 Russia finally joined the World Trade Organisation (WTO) and we can fully expect that as a condition of membership, other countries will insist they respect International patents and copyrights.  When this happens we can be sure that Microsoft will go after ReactOS.

For now though the operating system is looking like a feasible alternative to Windows XP when all support ends in two years time.  By then the new clone OS should be finished, tested and stable and any person or company looking to migrate their ageing software and hardware library in a way where everything will still run, and where they will still be able to get support will have an alternative.

Microsoft’s lawyers no doubt already have their pens sharpened however and it’s all still to play for.  Watch this space and we’ll keep you updated.

FreeBSD 9.0 Has Been Released

The operating system FreeBSD 9.0 has been released yesterday. The new version introduces several new technologies, feature additions and updates, including USB 3.0 support, the TRIM command for the Fast File System which improves interaction with Solid State Drives (SSDs), an update to Storage Pool Allocator version 28 which adds support for data deduplication and triple parity RAIDZ, and support for the Highly Available Storage (HAST) framework which offers network based Raid 1 functionality for additional data redundancy.

Additional features include updates to Gnome version 2.32.1 and KDE version 4.7.3, support for high performance SSH, an update to the NFS subsystem which now supports NFSv4 in addition to version 3 and 2, and kernel support for Capsicum Capability Mode, “an experimental set of features for sandboxing support”.

Support for USB 3.0 and Fast File System TRIM support are without doubt two of the most important feature additions in FreeBSD 9.0. The USB subsystem furthermore supports USB packet filtering now, which can be used to capture packets which go through the USB host controller.

freebsd

FreeBSD 9.0 is the first update of the operating system after the February 2011 FreeBSD 8.2 release, and the first major version update in two years.

Users interested in all of the changes can access the highlights here or detailed change log here. Please note that both release logs are highly technical.

Users who never came into contact with FreeBSD or another BSD variant before should start at the Resources for Newbies that offers help in selecting the right FreeBSD version, installation instructions and tutorials that should get most people started after installation.

FreeBSD 9.0 can be downloaded from the official website. The operating system can be downloaded as an ISO image which needs to be burned to DVD first, before the computer can be booted from it to start the installation of the operating system.

Additional information are available at the official website.

Test Your PC’s Stability

Testing a PCs stability makes sense in a number of situations. Maybe you have made the decision to overclock your PC and want to make sure that everything runs well and stable, or you are thinking of giving away your old PC to a friend or family member who is not the most knowledgeable person when it comes to computers. Making sure that the system runs fine can save you troubleshooting sessions later on.

System Stability Tester is a free open source software for Windows, Linux and Mac systems that can stress test and benchmark a computer system. It does so by calculating up to 128 million digits of Pi which is extremely taxing for the processor.

When you first start the program you have the choice to run a benchmark or system stress test. A benchmark can be used to compare the results of a system to another system, the stress test to verify that there are no calculation errors.

You can also select the amount of Pi digits you want to compute, the turns, and the number of threads the computer should use for that task.

system stability tester

The stress testing application supports two pi computation algorithms: The Quadratic Convergence of Borwein and Gauss-Legendre with Borwein being selected by default.

Please note that you can only run a stress test if at least two threads are selected. The program then starts the calculation which can slow down the PC considerable during operation. Statistics are updated regularly that display the amount of calculated Pi digits, the state, and time it took to calculate them.

An overview at the top highlights the total amount of errors of the calculation as well as the processing time until the first error was detected.

You can optionally save a log file or a Pi file. The first saves basic information about the run, the second all Pi digits.

One of the core advantages of System Stability Tester is that it is available for Mac, Linux and Windows systems, which means that it can be used to compare the performance of computers running different operating systems.

Interested users can download System Stability Tester from the developer website over at Sourcerforge.

Celtx Media Pre-Production System

I have started writing a book. It is just that I have that idea in my head that I’d like to bring to paper. I first started to write it all down in Microsoft Word. I eventually started to encounter limitations in the software that made it more difficulty to keep an overview of characters, the main plot, subplots, ideas and all that good stuff that you pin down to avoid forgetting it.

Celtx is available as a free version for Windows, Linux and Mac OS X. There is also Celtx Plus, a commercial desktop version and an online studio version to manage team projects. Most users should start with the free version though to see if they can work with Celtx to create their novels, comic books, films, audio plays, storyboards or other types of media. The software is very versatile in this regard.

celtx novel writing

I’d suggest to load one of the demo projects on first start to get a feel for the program. A demonstration is available for each type of media supported by Celtx. The program layout adapts to the selected production type. If you have selected Novel for instance, you are presented with an interface divided into the project library, the novel’s chapters and the core text editor part. Other modules can be displayed, like index cards, the title page or the master catalog offering information about characters, items of importance or scene details.

One of the program’s strengths is the ability to add detailed information to the catalog. Character information for instance include a name and description, media, physical description, character traits, functions, motivation and backgrounds.

character information

Even better, information added to the catalog are automatically linked in the play, novel or script. Additional options include adding notes to any part of the media, external links to websites that offer information or are important for research, options to add a synopsis or history to the project library and a lot more.

The text editor is decent enough. While it does not offer the full functionality of an Office suite like Microsoft Word or Open Office, it offers enough text editing and formatting options to the aspiring content creator.

It feels a bit strange that all guides posted on the site are for purchase only. A good starting point for new users are the Celtx Wiki and user forum.

Some buttons in the program interface, like Toolbox or My Studio, lead to the add-ons page on the website. Add-ons need to be purchased before the functionality becomes available.

Celtx is a sophisticated pre-production system. More than 1.5 million users use it worldwide to create media according to the project’s homepage. The program can be downloaded for all supported operating systems from the developer website.

Why Are There Two Explorer.exe Processes Running?

I check the running processes on my Windows system regularly to find potentially malicious or unnecessary processes. When I looked at the process listing today I noticed that two explorer.exe processes were running. I remembered that this could be a sign of malicious software disguising itself as a system process. When I checked the process paths I noticed that the location was identical and the standard explorer.exe location in the windows\system32\ folder.

Still, it felt strange that two process were started instead of just one. It took a bit of investigating to find the reason for this behavior.

When you look at both processes you will notice that they act independently of each other. You can see that for instance by looking at the memory usage or cpu utilization.

Two explorer.exe processes

I’d like to point out that you need to make sure that the two explorer.exe processes, or at least one of them, is not malicious in nature. It is a good idea to check the path first, if you see a different path for one process you may have a virus problem. You can check both explorer.exe files then over at services like Virus Total to check the files for malicious contents.

A settings in the Folder Options configuration of Windows Explorer explains the existence of two explorer.exe processes. Open Windows Explorer and click on Tools > Folder Options. Switch to the View tab there and scroll down until you find the following preference: Launch folder windows in a separate process.

If the preference is checked you have found the reason why two explorer.exe windows are running on your system. You can uncheck the option to have only one Windows Explorer process running at any time on the system.

The core reason for enabling the option is stability. It is usually safe to disable the feature so that only one explorer process is running on the PC.

Using LiLi to create a Bootable, Portable and Virtualized USB Drive

LinuxLive USB Creator, or “LiLi”, is a quick way to create Live Linux USB drives that are persistent virtualized drives. Typically, Linux USB drives require rebooting to install software. It is possible to create a Linux USB drive that will install without a reboot. This is where LiLi comes into play. By setting drive persistence for the USB, you are able to save files and settings on the USB which would normally be lost once the Linux USB drive is dismounted. Creating Linux USB drives is not an unfamiliar subject, but using LiLi is different. It is the feature of drive persistence that makes this method unique. There is also the ability to open your Linux OS in Windows with a portable version of VirtualBox.

Download and install the latest version of LiLi from the link that follows.

Follow all of the steps in the installer and click Finish at the end. Check the box to “Run LinuxLive USB Creator”. The application will launch and you can get started if you already have the LinuxLive ISO downloaded or on CD/DVD.

If you do not have a Linux ISO downloaded or on CD/DVD, you will need to download the ISO first. There is no need to burn it to a CD or DVD unless you want a hard copy. You can download it to your hard drive and LiLi can access it from there. Not all versions of Linux are compatible with LinuxLive USB Creator. Ubuntu, Knoppix, and LinuxMint are good LinuxLive options. One that works very well with this method is Fedora. A link to download the Fedora ISO is included here. Unlike many of the Linux ISO downloads, this one does not take long to download and is definitely compatible with LiLi. (check out Distrowatch’s list of major distributions for other downloads)

At the LiLi interface, you will find that it is broken down into 5 steps. Just follow the steps in the order listed to install Linux to your USB drive. The first step is to choose the USB drive or other portable USB device for installation.

linux usb bootable

If the volume is formatted in NTFS, you will later need to format it in FAT32. We will get to that, but you may as well format your USB in FAT32 before starting. In step 2 you will choose whether to use an existing ISO/IMG/Zip file, CD, or tow download an ISO from supported distributors.

source

LiLi will then check the ISO to ensure that it is a good file and is compatible.

source compatible

In step 3, you set the amount of space for drive persistence. This is how you will be able to save files and installed programs between reboots. This does take up drive space, but it is well worth it to have the persistence. The larger the capacity of the USB drive, the better if you will be adding many programs and files.

persistence

In step 4, enable Launching LinuxLive in Windows and this will download portable VirtualBox to the USB. If the USB drive is already formatted in FAT32, you can leave that box unchecked. If it is formatted in NTFS, check the box to format in FAT32. Click the lightning bolt image in step 5 and the drive will be created. When it is complete, you will see the sign of success:

To use your new LinuxLive key, open Windows Explorer and open the USB drive, double-click VirtualBox\Virtualize_this_key.exe and portable VirtualBox will be launched and your installed version of Linux will open.
