The Progress of Thin Clients

admin — Mon, 05 Apr 2010 15:14:37 +0000

When thin clients first appeared on the market over 10 years ago, IBM was a great proponent of this technology even though the first units had slow CPUs, limited memory, and Linux-based operating systems.
In the early days of thin clients, networks were still employing hubs instead of switches. Hubs share all network traffic with all the attached devices; therefore, this type of technology did not work well with the boot-server type of thin clients. In other words, when many thin clients were started at the same time, the network was unable to handle the traffic caused by downloading the OS to every thin client.

Windows CE

As time went on, new operating systems like Windows CE were developed,. Networks started to use switches, eliminating the need to share bandwidth between devices while being capable of full duplex traffic (sending and receiving at the same time). Small in size, Windows CE could fit on the Disk-On-Chip (DOC) mounted inside the thin client as well as provide a place to embed applications.
Windows CE, however, had its own challenges. In addition, the Windows server platforms (NT Terminal Server and Windows 2000 Server) and the early version of Citrix were delivering what people expected from a server platform for hosted applications in colors, compression and encryption.

Thin Clients Today

Over the last few years, the average CPU speed has increased to over 500 Mhz. With a faster CPU, running Linux or embedded Windows XP (XPe) has become much more feasible. These operating systems are better-suited to running local applications; in addition, many provide full-function browsers with Java Virtual Machine (JVM) capability, email, enhanced terminal emulation, and much more of the functionality that users are used to seeing on the PC.
Windows 2003 for thin clients now has high-color support, sound delivered to the desktop, data compression, and better printing support. Citrix has also updated its product to provide better security, better compression, bidirectional sound, published applications, and security enhancements such as smart card and biometric device support.
Consultants have been saying for a long time that thin clients are the future. Thin client technology has finally caught up with the vision. Most intelligent thin clients can work nearly like a PC, giving the user all of the desired flexibility and performance while providing the data processing department with its control and security benefits.
Today there are many thin client models to choose from with varying CPU speeds, memory capacities, storage capacities, and operating systems.

Customized Thin Clients

Customization of thin clients is gaining importance with both Linux and XPe models because customers have their own ideas of what is needed on a machine. Thin-client manufacturers that can respond quickly to customization requests are gathering momentum in what is becoming a huge market.

Sophisticated Printer Support

As a company requires printing of more complex types of data, such as barcodes, it is critical that the chosen thin-client technology can handle necessary printers and data streams. Barcodes require a more sophisticated printer session on the thin client.

Tablet Thin Clients

A new thin-client device that is proving to be beneficial to many companies is a wireless tablet. The tablet takes the place of a hand-held barcode scanner with small display
In a warehouse environment, since inventory control software normally comes from an iSeries, a fixed terminal from which data is entered and checked is usually placed somewhere in the warehouse. Some thin-client manufacturers now sell wireless thin-client tablet displays so that existing full-screen inventory programs can be used directly on the tablet anywhere in the facility, eliminating the need to modify the inventory program. The tablet can be carried by the user with a neck strap or mounted on a forklift or on the wall.

All-in-One Thin Clients

Another growing trend is the use of “all-in-one” thin clients. These thin clients have the thin-client technology contained inside an LCD flat-panel monitor. The benefit here is to minimize the amount of desk space used and remove the clutter of additional wiring. The apex of this is a wireless all-in-one unit with a touch screen.

Biometric Security Features

The ability to secure access to thin clients with a biometric device is beginning to appear in thin-client applications. A biometric device is a fingerprint reader that is either a direct-attached device or a device that connects via the mouse, keyboard, or monitor. When prompted, the user places his or her index finger on the reader and the device verifies identity by comparing the fingerprint with those already recorded. Once a user is verified by a biometric device, the thin client can start various programs based on who the user is and how the software is programmed. Biometric authentication saves time, provides an additional layer of security, and eliminates the need for users to remember their passwords.

Using Linux

admin — Mon, 05 Apr 2010 15:13:00 +0000

Just about everybody on the planet has heard about the open-source operating system called Linux. Heck you can even talk to her grandmother and she’s heard about. But funny enough it’s almost like folklore to the common person. Everybody’s heard about but nobody really knows anything about it or is even seen it. I was once joking that Linux is a lot like the Sasquatch. It’s an elusive beast that seems to not be taken serious by anybody but is been taken very seriously by many Fortune 500 companies.

Let me take a second to explain myself. I personally use Linux within my business for many years. One of the main reasons I did was not to save money but to provide flexibility to my business. I’ve nothing against commercial corporate systems but sometimes I find that this open-source offering system augments those other systems very well. For example when building a server for a small company I find that Linux fits the bill at times much better than Windows server does.

Also for web development I find that Linux is the platform you want to develop on. It’s very robust and very secure. It has the benefit of many years of its UNIX roots. Whereas other operating systems are playing catch-up. I’ve worked with many companies large and small have used Linux to run their web-based applications within the company and to the outside public. You can service more clients, faster and better. Plus there’s a large development community that has probably encountered every problem that you may encounter on your server. Because it’s open source most of the information is also open-source.

If you’re interested in using Linux or introducing it to your clients if you are a computer person I’m going to give you simple recommendation. Don’t try to sell Linux as Linux. Sell a solution like a low-cost file and data backup server. Sell its benefits not its name. Another unfortunate thing that has occurred to the general public when it comes to Linux is the fact that many people don’t take this offering system seriously. Many think it’s just a toy. Whether you believe it or not this is one serious operating system. It’s extremely robust. As a side note it’s important to note that it is so robust that it can run for years without a reboot. So instead of trying to defend the Linux name simply install a solution based upon Linux and let them ask you what it is after their very happy with what you’ve done. When they discover that their business runs on Linux you already have made them a convert. In other words you’ve shown them the Sasquatch!

Thin Client Computing Without “The Bill”

admin — Mon, 05 Apr 2010 15:09:32 +0000

Corporate America has been looking for ways to reduce the cost of ownership associated with Microsoft Windows®-based computing causing the popularity of Windows-based Thin Clients coupled with deployment of Terminal Server and Citrix grow at a rapid rate. A new trend has been developing; enterprises are now trying to reduce costs further by moving to “intelligent” Thin Clients.

In contrast to “dumb” thin clients, which simply acted as terminals allowing access from desktops to server-based applications, “intelligent” Thin Clients come with built-in emulation software; e-mail; a full-function browser–such as Mozilla Firefox or full Internet Explorer–supporting JVM, Flash and XML; and pop-up window support. These intelligent Thin Clients are served up with Linux or Windows XPe operating systems, and allow access to a file server as well as Web-delivered applications such as Lotus Notes, WebSphere, etc.

Several options now exist for companies wishing to deploy Microsoft Office-type thin client products:
Traditional: Serve up these applications using Microsoft Terminal Server (2000 or 2003 server), Citrix, etc., delivered using a remote desktop protocol. Costs associated with this method are: Terminal Server Client Access License at $120; Client Access License at $30; Microsoft Office Professional at $395; and Citrix (if applicable) at $250. The total software cost per user is $545 to $795. The total cost of ownership for software and hardware (Windows CE Thin Client) in a LAN environment is $994 and in a WAN environment is $1,194.

Hybrid: Keep Microsoft Office and serve it up using a Linux server and CrossOver Office. This product allows some Microsoft products to be installed and served up via X-Windows to a Linux desktop or Linux Thin Client. The costs for this method are: CrossOver Office at $50 and Microsoft Office Professional for $395. The total software cost per user is $445. The total for software and hardware (Linux Thin Client) in a LAN environment is $895 and in a WAN environment is $995.
Local Linux: Install OpenOffice on a Linux Server and use X-Windows on a Linux desktop or Linux Thin Client. The cost of this method is: X-Windows at no cost and OpenOffice at no cost. The total software cost per user is $ 0. The total cost of ownership for software and hardware (Linux Thin Client ) in a LAN environment is $450.

Versatile Linux: Purchase a Thin Client with embedded OpenOffice. Files are accessed / stored via a Linux or Windows file server. This option incurs an additional cost for a hardware upgrade since it requires more disk space and more memory. It is best suited to remote users, as X-Windows can be bandwidth-intensive and is therefore not recommended for WAN use. Cost of this method: OpenOffice at no cost and additional memory for $125. The total software cost per user is $125. The total cost software and hardware Linux Thin Client) ( in a LAN/WAN environment is $575.
Remote Linux: Install OpenOffice on a Linux Server and serve up applications using the Tarantella Enterprise 3 product. This option supports compression and encryption of the X-Windows protocol, allowing applications to be served up efficiently on a WAN. The cost of this method is: X-Windows at no cost; OpenOffice at no cost and Tarantella Enterprise 3 at $100. The total software cost per user is $100. The total for software and hardware (Linux Thin Client) in a WAN environment is $550.

Corporate management has come to realize that the PC revolution has its drawbacks. These drawbacks include higher maintenance costs, lower employee performance, and system vulnerability. The hardware become obsolete and higher performance CPUs are required. Operating systems typically need updating every three years. When you figure in the licensing fees; the time spent by system administrators updating each workstation, installing and maintaining anti-virus software; the downtime this causes other employees; and the additional time required by employees to learn each new revision; the resulting price tag is quite sizeable!

There is currently a growing trend for Thin Clients using embedded emulation alongside server-based or Web-delivered applications. This trend has generated new interest in terminal computing, specifically in the field of thin clients. Linux Thin Clients in particular allow server-based computing without the additional licensing and provide file server access enabling complete independence for applications, whilst maintaining sharing and back-up control.

Top Ten Concepts for Linux Beginners – Number 2, Directories

admin — Sat, 30 Jan 2010 02:52:12 +0000

Linux people like to claim that directories are really just another type of file. This statement can be misleading. We saw in a previous article that you create a file using a file editor. We will see later in this article how to create a directory.

So just what is a Linux directory? A directory is a collection that may include one or more directories, one or more files, or in fact be empty. You may think of a directory as a computerized file folder or loose-leaf notebook that contains dividers (themselves directories) and pages (files.) Just like a notebook page may not contain a divider, a Linux file may not contain a directory.

Up to now our comments about Linux directories hold for Windows directories as well. Now let’s take a look at some differences between these two systems. First come the naming conventions. Linux always distinguishes between lower-case and upper-case characters in directory names. Microsoft Windows does not. For example, Linux treats pay12june and Pay12june are as two different directories, as different as the directories pay12june and heighho. These directory names were used as file names in the previous article. While Linux does have some reserved directory and file names, in general one cannot tell by the name whether it is a file name or a directory name. So be careful. Linux helps you out here ‘ the ls command that lists the contents of a given directory usually displays files and directories in different colors.

Directories are hierarchical. They resemble a tree or a family tree. But unlike a tree (or Microsoft Windows) Linux has only one root. The root, designated as / lies at the top, rather than at the bottom, of the hierarchy. Right underneath the root directory you will find several subdirectories. For example, the /home directory is a child of / the root directory. The number and names of the first-level subdirectories vary from one version of Linux to another. For example, some Linux distributions include a /root directory while others do not. The /root directory (or subdirectory, both terms are used) is a child of /, the actual root directory.

The /home directory is an important directory. It is divided into subdirectories, one for each user. We like to work with Damn Small Linux, a free version of Linux that runs on the Windows desktop and requires only 50 Megabytes of disk space. Damn Small Linux automatically creates a user called dsl whose home directory is /home/dsl ; a working area essentially reserved for this user. All Linux versions subdivide the /home directory into user subdirectories according to this simple naming convention.

Linux provides several commands to process directories. For example, the mkdir command creates a directory. The rmdir command removes a directory, but in the simplest case only when it is empty. The cd command changes the working directory, the directory in which you are positioned. The pwd (print working directory) command displays (not prints) the working directory. Beginners should run this command often to reduce errors. For example, if you, the dsl user, think that you are positioned in the /home/dsl directory but in fact are positioned in the / directory you won’t be able save your files with a simple command. Why? Because you lack the requisite permission, the subject of our next article.

Linux Operating System Errors and Resolution

admin — Fri, 29 Jan 2010 18:14:50 +0000

HTML clipboard

Linux is the most popular operating system so far as security and performance is concerned .It is a Unix-like operating system and is the best example of open source development and free software; generally all underlying Linux source code can be modified, redistributed and used freely by anyone. Red Hat Enterprise Linux 5.2 is the latest version of Linux operating system.

As we all know every operating system has its demerits or failures and can give errors at any time with out any prior information. There are some common error messages faced by Linux users while using this operating system. Some of the most common ones are the following:

• Unknown terminal type Linux.

• Unrecognized option ‘-m486′.

• bdflush not running

• cannot read table of mounted file systems

• Unknown terminal type Linux.

• Cannot initialize drive XYZ?

• EPERM Operation not permitted.

• Unrecognized option ‘-m486′.

• Modprobe can’t locate module, “XXX,” and similar messages.

• Mounting unchecked file system.

• EINTR Interrupted system call.

In most the situations given above a user faces any of the mentioned problems, it becomes difficult for him/her to access or manage his data. He/she won’t be able to do normal tasks which can otherwise be performed effortlessly. If the data which has been rendered inaccessible is important then it becomes essential to recover that data as soon as possible. In this case, he/she would need the help of Linux data recovery software.

Linux Data Recovery Software is an ultimate way out for all Linux related data recovery problems. It also recovers data from formatted hard drives also where file systems have been changed. It recovers lost logical drives and data from physical disk or any removable media.

Stellar Phoenix Linux Recovery software provides data recovery from Ext2, Ext2 and Reiser FS file systems of Linux operating system.

Counting the Cost of Free: What Value, Linux?

admin — Fri, 29 Jan 2010 14:42:36 +0000

Lora Bentley spoke with Amanda McPherson, marketing and developer programs VP at the Linux Foundation. She and two colleagues recently released a new paper, “Estimating the Total Development Cost of a Linux Distribution.”

Bentley: Your study found that it would cost $1.4 billion for a company to build the Linux kernel from scratch today, and $10.8 billion to build an entire Linux distribution similar to Fedora 9. Can you explain how you reached those figures?

McPherson: The conclusions were reached by using David Wheeler’s well-known SLOC tool, SLOCCount, which makes use of the industry standard COnstructive COst MOdel (COCOMO). This methodology takes into account lines of code written, the appropriate number of labor years, and salary adjustments for inflation. We wanted to come up with a real number based on the one thing you can quantify in open source — code. We used a well-regarded methodology and tool that had been used before. Instead of making random projects, we thought this was the best way to approach it.

Bentley: Why the Fedora community distribution and not another?

McPherson: Fedora is the basis for Red Hat Enterprise Linux, which represents a large percentage of the Linux market. This provided us with a very relevant model to assess. Also, David A. Wheeler had used Red Hat for his study in 2002. OpenSuse and Debian/Ubuntu would, of course, also be great targets for this study. We may do that at a later date. We also would like to use an embedded distribution.

Bentley: What do or should these findings mean to proprietary software vendors?

McPherson: I think it means the future of software development is collaborative. These systems have grown so powerful and so important that for any one company to fund the development on its own would be a foolish and possibly financially untenable decision. Software development today actually requires collaboration in order to innovate at the pace the market demands. Consider devices like the Kindle and Gphone. They wouldn’t likely be available today were it not for the billions of dollars worth of R&D that they can use from the Linux kernel. You see companies like Intel using Linux and open source components in the Moblin project to expand the use of netbooks running its products. Intel could instead develop proprietary software in-house to meet this need, but why would they when they can make use of billions of dollars of free R&D? Things have changed since the desktop computer revolution.

Bentley: Don’t many proprietary software vendors recognize the value of open source now given that so many use open source in some way or another?

McPherson: Absolutely! You can also look at our “Who Writes Linux” report to see that hundreds of companies support Linux development directly. This study shows that those companies (such as IBM, Intel, Red Hat, Novell and HP) have made a very smart decision. They can fully participate in a large ecosystem and make use of free R&D without having to shoulder the burden all alone.

Bentley: So why is a study like this one helpful?

McPherson: Sometimes it’s easy to take a ubiquitous piece of technology for granted, especially one you can use for free. I think it’s not just Linux we take for granted: Just imagine the R&D value of the Internet itself and what that means for our economy. Compared to that, Linux seems small, yet when you think about all the innovation it’s powered or is powering, you start to get the idea. I honestly can’t imagine where we would be if Google had had to pay a company a per-server fee for its servers. I do not believe the economics would have been there to build out the powerful search network that we all use everyday. This study makes us appreciate the sometimes-unheralded piece of software and the license that has powered this innovation.

Bentley: Do the findings have added significance in light of the current economic climate?

McPherson: I think so. Linux has always been a lower-cost alternative to Windows, but this report illustrates its economic impact on technology innovation. It’s exciting to see how the collaborative development model is fueling a new category of devices and technologies that would be at least a decade into the future if it weren’t for Linux. Let’s remember that in software, time is money; oftentimes time is more important than money. For a company like Google or Intel to be able to make use of this code that has taken years to develop, drives innovation and keeps costs low for consumers.

Linux Web Hosting: a Comparative View of the Web Hosting Server With Others

admin — Fri, 29 Jan 2010 12:32:05 +0000

Indeed, complex features, like e-commerce, database utilities and bulky dynamic pages invite different nature of web hosting requirements than a much simpler and lighter web site. Obviously small scale web masters cannot afford to surpass their budgetary constraints in order to chase technology at its latest. In the given scenario, triggers on the search for cheap and efficient web hosting services for across the board scales and sizes of websites by their respective web masters. And as the quest for cheap web hosting services assumes pace, all hopes turn to Linux web host services for obvious reasons.

Linux web hosting, being an open source software product, is not only substantially cheaper, but also provides a lot of scope for customizations and enhancements at advanced stages. Apparently, Linux – based hosting is most popular with small scale business owners vying to make it big on World Wide Web.

Delving deeper into the advantages of Linux hosting over windows –based hosting reveals that there are different layers of reasons that put Linux –based web host services over and above the Windows –based web host services.

To begin with, the licensing fee for Linux hosting plan is way lower than Windows hosting that contributes to its cheaper status.

Further, Linux web hosting servers can support much more complex nature of websites with equal ease as they sustain the simpler websites. What’s most noteworthy about it is that quality is not at all compromised in the process.

Also, a Linux hosting server is conveniently convertible to a Windows based website without any hullabaloo.

Linux web host services are compatible with all kinds of web – based database systems, including My-SQL and MS-SQL. Likewise, all kinds of open source scripting languages like My-SQL, PHP and Perl can easily communicate with your website through Linux web hosting.

Not to mention, the extent of security offered by Linux based web hosting services is matchless, as compared to any other hosting service.

Given the breadth of advantages of Linux web hosting, coupled with both technology and ambitions on a rise; it is ubiquitously witnessed on a global scale that there are more companies working on the Linux hosting, than on any other web host services. Linux web hosting is an easily predictable future of all web host services, because it is safe, fast, friendly and cheap.
