Tagged Under : , , , , , , , , , , , , , , , , , , , , , , ,

This is perhaps one of the most difficult questions to be answered with a plain simple answer. Before we decide on the most compatible operating system for web hosting we need to delve a little further to know what an operating system is and why is it being given so much importance.


What is an Operating System?


The applications that you can use on your computer, the internet chatting and browsing dealings are all possible due to the help of the operating system. Operating systems are the backbone of computers that help you in completing your task with ease.


Most of the computers use the Windows operating system such as ME, XP, NT and several others. These programs are operating systems. This operating system is also vital for the functioning of the host server. Now let us determine the types of operating systems and their viability


Windows Operating System


Windows is a product of Microsoft designed for the running of the web server. The beauty of Windows is that it has a unique integration of various Microsoft products It also facilitates your website to run Active Server Pages and also allows you to integrate SQL databases.


The only disadvantage with the Windows operating system is that it is very expensive. Also if you do not have enough experience maintaining Windows from a remote location the procedure can be a very tedious and time-consuming one.


Linux Operating System


Linux is a second version created by some individuals who were the pioneers for designing Linux operating systems main portion. The introduction of some of the parts led to customization of the operating system meant for special uses.


One of the advantages of Linux operating system is PHP and the biggest advantage is that Linux is freely available. This is also a very stable and secure system. There are many companies that are involved in Linux marketing such as Red Hat and Debian.


Unix Operating System


This is the third version of the operating system which is somewhat similar to Linux. Unix has 2 operating systems. One is OpenBSD and the other is FreeBSD. The advantageous point to be noted is that once you install the Unix operating system they are very robust and will give you no trouble.


But the trouble lies in the installing part. These systems are very difficult to install. OpenBSD is the preferred one among the operating systems. Both these systems are freely available.


Which to choose?


We come back to the basic question of which one is ideal. Depending on your requirement you should choose your operating system. For example, if security is your priority then you should opt for OpenBSD.


If you are looking for compatible various Windows products then you should opt for Windows. If your main concern is PHP compatibility then you should choose Linux. You need to choose the best operating system that would help you achieve your goal.

Linux has the tools and applications you need. Programs ranging from the market-dominating Apache web server to the powerful GIMP graphics editor are included in most Linux distributions. Free and commercial applications meet are accessible to meet most application needs.
Linux interoperates with many other types of computer systems. Linux communicates using the native networking protocols of Unix, Microsoft Windows 95/NT, IBM OS/2, Netware, and Macintosh systems and can also read and write disks and partitions from these and other operating systems.
Linux has a low total cost of ownership. Although the Linux learning curve is significant, the constancy, design, and breadth of tools available for Linux result in very low ongoing operating costs.
Linux: changes one makes in Open Source software will benefit each and everyone, all over the world. Without exceptions or restriction. (Key Advantages of Linux)

Open source software is an up-and-coming type of software that may essentially influence the business and economic features of the software industry. Linux, an open source operating system, has been the important example of the likely of the open source movement, opposing Microsoft Windows, the current operating system.

Lerner and Tirole (2001, 2002) discussed the motivation of individual programmers and software firms to participate in open source projects. They argued that programmers are goaded by peer recognition and career benefits such as being hired by a software firm or getting access to funding for future software ventures.

Mustonen (2003) found a model in which the participation of programmers in open-source projects and shows that a low implementation cost of an open-source application is crucial for its survival when it battles with a proprietary application.

Linux is becoming mainstream and the Linux-based packaged software market is expected to exceed by 2008.Linux has been mostly an operating system for power-users who have Unix-like skills, but this may alter since the open-source community is raising several friendly user interfaces such as KDE.THUS Linux does have the potential to have a wider distribution and more popularity in future.

Are you unable to boot your computer from Linux operating system in a dual-boot configuration with Windows? Your system cannot recognize the Linux partition and you cannot access your data from the system? This behavior renders your Linux partition inaccessible and your valuable data irretrievable. Such problems may occur due to missing or corrupt hard drive data structures. It leads to significant data loss, if your backup is not updated. In order to recover lost data in these cases, linux data recovery comes for your rescue.

In a practical scenario, you may come across the below error message after you install Windows XP on a computer that has Linux Ubuntu already installed:

“root (hd1,1) Ubuntu/disks
Error 22: No such partition”

This problem occurs when you make your system dual-boot. After the above error message, boot process fails and you cannot gain access of your Linux partition. To get your valuable data back, you need to identify the root of this problem and perform data recovery linux by resolving it.

Grounds of the issue

You may encounter this problem due to corruption to the Linux partition or file system. Linux cannot read a damaged partition and access boot files from it.

A computer hard drive is divided into several partitions, which work as individual drives. You can use different file systems and can install different operating systems on these partitions as per your requirement. The hard drive partitioning is particularly useful for effective management of your precious data.

The hard drive partition and file system may get damaged due several reasons, such as virus infection, improper system shutdown, power outages, user mistakes, file system conflicts, and more.

Resolution

Try out the below methods to sort out this problem:

Boot your system from boot disk of Ubuntu operating system.

Run fsck tool to check integrity and consistency of your hard drive partition.

Format your Linux partition and reinstall the operating system.

Formatting can fix this problem, but it also removes all the data from your Linux partition and cause severe data loss. In such cases, Linux Recovery is the only way to go.

The Linux Data Recovery software enables easy and absolute recovery of all your lost data with advanced scanning techniques and simple graphical user interface.

Stellar Phoenix Linux Data Recovery is the most powerful utility that provides assured recovery of all your mission-critical data. The software supports all major distributions of Linux operating system, such as Ubuntu, Red Hat, SUSE, Fedora, and Debian. It is a read-only application that safely recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

Resolving ?Must load Linux kernel before initrd? Error Message in Linux Operating System

Tagged Under : , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Boot loaders such as GRUB (Grand Unified Bootloader), LILO (Linux Loader) etc. enable you to select to boot a particular operating system in multiboot or dual boot systems. After selecting the operating system (for example Linux), the booting process initially starts with the booting of Linux Kernel program. A Linux Kernel program is the central component of a computer operating system. It requires the corresponding drivers to access the device on which the file system is based. To avoid any conflict due to all imaginable drivers in the kernel, it uses initial ramdisk (intrd). The intrd is the temporary file system, which is mostly used for preparations before the real root file system can be mounted. Problems might occur when intrd gets loaded before Linux Kernel program. In such situations, the hard drive volume becomes un-mountable and the data saved in the hard drive becomes inaccessible. In such situations, you need to recover your data from the latest backup. In case, no backup is available or the backup is corrupted, you need to use efficient Linux Data Recovery applications to recover your lost data files.

Consider a practical example, when you attempt to boot Linux operating system, you encounter the below error message:

“Must load Linux kernel before initrd”

The above error message occurs each time you try to boot the Linux operating system on your computer. After the above error message appears, the data saved in the Linux volume becomes inaccessible.

Cause:

The above error message mainly occurs when the intrd gets loaded before the Linux Kernel program.

Resolution:

To resolve the above error and access the data, you need to remove the intrd from your computer. However, if you still encounter an error, then only option left is to access the volume by reinstalling the Linux operating system. A clean reinstall of the operating system will erase all previously stored data in the hard drive. In such scenarios, you need to recover lost data by using effective Linux Data Recovery software. These advanced recovery applications incorporate high-end scanning methods to recover lost data from a logically corrupted hard drive.

Stellar Phoenix Linux Data Recovery serves the purpose of providing reliable and easy Linux Data Recovery. This read only Linux Recovery software supports Ext2, Ext3 and ReiserFS file systems. It gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive should be connected as slave.

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.

Top 3 Operating Systems for E-Readers

Tagged Under : , , , , , , , , , , , , , , , , , , , , , ,

During 2009, e-readers were operating at maximum efficiency with over 2.2 million devices being shipped to stores. In 2010, the demand for e-readers is expected to increase by more than 50%. Their operating systems create the necessary base for these popular devices. Many first-class eBook Readers run full operating systems and can function like a computer.

Google Android

It is not surprising that Google Android tops the list of operating systems for e-readers. The Barnes and Noble ‘Nook’ was the first e-reader to use Google Android. Since that launch, Google Android has been used in various e-readers and that trend is expected to continue into the future.

Google Android gives users access to 1,000,000 free, public-domain books digitized by Google. All devices using the Android system can tap into Android apps and vice versa. In addition, Google understands that the real power of the open source Android lies with the Operating System Defaults. Google eBooks will serve as the default on every Android device.

The innovative eDGe e-reader, created by Entourage Systems, runs Google Android operating system. The eDGge is a netbook/e-reader combination which offers users the convenience of a Google toolbar on the right screen. Running on Wi-Fi and 3G networks, users can surf the internet, watch videos, or engage in video chat with this device.

Spring Design’s ‘Alex’ will also support Android apps. Yet any applications which require internet access will work only with Wi-Fi. With this dual-display e-reader, the 6.5″ e-ink screen for reading sits above a 3.5” color LCD. Users can display images and video, view notes, and even browse the web.

Expected to be released in 2010, the proposed Netronix, a collaboration between Texas Instruments and a Taiwanese networking specialist, is also an Android-based e-reader. Android e-readers allow portability of books (between Android e-readers) as well as access to Android apps.

Linux

The new Skiff reader is a Linux-based system. The Skiff reader is said to be the largest (11.5″) and thinnest (0.25″) with the highest-resolution (UXGA – 1200 x 1600). The Skiff reader is expected to be on sale later in the year. Interested buyers will be able to find it online and at over 1000 Sprint stores in the US.

Sony Reader runs the MontaVista Linux Professional Edition operating system. Sony ebook Library is not supported on Linux. Yet when this device is connected, it grants access to its flash memory and memory card slots (as if they were USB Mass Storage Devices).

Amazon’s Kindle DX runs Linux-2.6.22.19. Operating system updates are received wirelessly and install automatically during a period in sleep mode in which the wireless is in operation. As it was noted in the article “Amazon Offer Kindle for Sale in Europe – Will they Succeed“, the device is being offered globally on the 3G network with no charges for the wireless connectivity that is used to download eBooks (Digital Book Readers). With its Wacom touchscreen, Illiad runs Linux 2.4 kernel.

Due to its open Linux operating system, Illiad can run third-party applications created for it. The Hanlin eReader v3, one of the first Open Source e-readers, is built on the Linux operating system. China’s Hanvon uses Linux 2.6 and Cool-er, Pocketbook, and Bookeen also run Linux.

Windows

Although Windows is slipping in popularity, it will remain a major player in operating system market for many years into the future. Sony PRS-505/SC Digital eBook Reader, with its company software Sony ebook Library, is similar to iTunes and requires Windows. The software will not work on the 64-bit version of Windows XP but does support Windows Vista and Windows 7. Recent announcements point to the use of Windows 7 in new color ‘slate’ e-readers such as Archos or HP. The Taiwanese company, MSI, has also created an e-reader/computer combo which runs Windows 7.

E-readers with operational systems, such as the leading Google Android, encourage openness. These innovative devices are ‘cracked’ to allow users to run Android apps as well as download music and access social networks. Yet Fortify Software, the application vulnerability specialist, has issued a warning to corporations about possible security issues with modified e-readers. When a devise is ‘cracked’ or repurposed in this manner, there isn’t any way to check the security of the operating system ‘cracks’ or newly installed programs.

For usage outside the corporate world, however, e-readers have few drawbacks. E-reader companies are always trying to improve on features, performance, and design. E-readers have made a tremendous impact on the reading experience – what we read, where we read, and how we read books and newspapers. More and more people are choosing e-readers and their state-of-the art operating systems are helping to drive that demand.
