Pros and Cons of the Major Operating Systems

By Dean Walden

There are several options when it comes to choosing an operating system for your computer. Of course Windows is the overwhelming heavyweight in the market place and it isn’t a bad choice in some ways, especially for those not interested in the nuts and bolts of things. Also looking for users are Linux, BSD and Leopard.

1. Windows

The good side of Windows is that it is made to operate programs. The rich variety of software that works here is a huge selling point. You don’t have to be a programmer or even a techie to be a user. Everything comes from a disc or a download. Click the install button and away you go. Word processors, Spreadsheets, Games, Synthesizers, Photo Editors, Art Creators, Email Handlers, Bookkeepers and Website Makers are some of the most common. Then there are the not so popular yet also intriguing out of the mainstream volumes such as File Converters, Iso File Makers, Virus Hunters, Adware Killers and endless utilities you may discover once you start looking. There is a small utility that saves clips (as many as you want) that can be pasted anywhere so you don’t have to retype all the time.

That’s the good side of Windows. Just so you know it’s not all roses and candlelight you should know there are some drawbacks too. Everything you do on Windows should be backed up regularly. Why? Because just about the time your five week project is within a few paragraphs of completion, Windows will have a hiccup and lose the whole thing or some virus will erase your hard drive, or you’ll press the delete button accidentally. Boom, it’s all toast. Another thing about Windows is that it’s already programmed, you have to accept it as it is. If it doesn’t have a feature you need, you’re out of luck. If the button arrangement is not convenient (although there is some flexibility), you must adapt. Don’t need all the bells and whistles? Your stuck with them. Then there are the slow days when it all just seems to sit there and mock you taking it’s sweet time. It’s no wonder someone occasionally tosses one out the 10th story window.

2. Leopard

So, what are the other options? Well, first is Leopard which is the Macintosh operating system. Macintosh is made by Apple Computers. If you don’t know who Steve Jobs is, you must live in a dark and deprived world. Macs, as they are known, cost a little more than others systems (about twice the price of a Windows machine). I will tell you right here that I have yet to meet a Mac user that has a bad word to say about his or her machine. If you get one, you are practically guaranteed to love it. They are the choice of graphic artists almost universally. The local ad sheet for the city is made on them, so they make commercially viable tools.

The negative side. Not a lot really. There isn’t as much software made for them, but the ones you get are extremely well made. A lot of the less popular stuff doesn’t exist for Macs. That along with the higher price are the main hitches.

3. Linux

Another option is Linux. The Linux operating system is actually free at this time so the price is right. There are many flavors (versions) of Linux, so you don’t have to use the same thing everyone else has.

Some that I know of are:

  • Red Hat
  • Ubuntu
  • Suse
  • Damn Small

Each one has advantages and limitations because they are geared toward a certain area such as games or internet or servers. They have a ways to go to become popular, yet are making great strides in market share. Also, if you can do the programming, Linux offers wonderful access to the code. In the last year or so, it has become quite easy to obtain and install Linux on any computer. In fact it will coexist right alongside Windows, so now there is little excuse for not trying it out. They offer a GUI similar to Windows and Leopard which is fairly intuitive. Some software is quite comparable to the bigger fish. OpenOffice will take Office on and come through looking pretty good. Gimp has a learning curve, but can do much of what Photoshop does for free.

The downside is that Linux is just not as developed. It is a terrific platform for geeks that love to swim through code and troubleshoot glitches. The creative potential is unlimited which is the main drawback at the same time. Most people want something ready to go, not something they have to create before they can operate. The number of programs (though growing) is quite limited.

4. BSD

The last of our operating systems to consider is BSD. Just like Linux, it is free (though there is a commercial version). The major selling point is that it is the most modern system. It doesn’t have the backward compatibility issues of Windows. So many advances in hardware have been made since windows was introduced that you wouldn’t believe some of it. BSD was created to take advantage of these advances. It has the most potential of all these systems because of it’s modern design. It is quite compatible with and similar to Linux, just more modern.

That at the same time is it’s largest problem. Most of the accessories that go with an operating system (software and interface) are lacking at this time. It’s like having a Ferrari engine and framework without the rest of the drive train.

Dean Walden is an avid internet user, watcher, promoter, website builder and researcher. The Ubuntu version of the Linux operating system is easy to use if you can use Windows.

Someone has developed a way to install Ubuntu on a Windows machine without interfering with Windows. To learn how to put Ubuntu Linux alongside Windows on your computer (with the Wubi installer), start at http://wubi-installer.org/
Once you have it downloaded, just start it and it will do the rest. Then the next time you boot up, you’ll have the option of Windows or Ubuntu. Once you try Ubuntu, you can shut it down and restart to go back to Windows.

Quick Overview of Bsd Systems With Main Focus on Openbsd
By Juraj Sipos

Most users who use Linux use it because they hate Microsoft; people who use BSD use it because they love Unix

History

To say it metaphorically, the Internet sprung out of BSD. It is not because these systems can handle the biggest traffic as servers, but because the concept of IP addresses and the TCP/IP stack is a BSD invention. If you right click on the file “winsock.dll” in Windows 98 (C:Windowswinsock.dll), you will see “BSD Socket API for Windows” in the Properties > Version window; however, the “BSD” is not seen in newer Windows systems in the “version information” window of winsock.dll. But there is a lot of writing on the Internet about this if you Google both terms: “winsock.dll” AND “bsd”. BSD systems have a different licensing policy and anybody can take their code. BSD license gives more freedom to programmers.

300px-Unix_history-simple.svg

From the above it is clear that Microsoft, too, used or “stole” this code, not only Linux. BSD grew up in the 1970’s with a Defense Advanced Research Projects Agency (DARPA) support. Version 4.3 BSD (1986), 4.3 BSD Tahoe (1988), BSD Net 1 (1989), and so on followed. The history is well described also on BSD sites. FreeBSD, for example, started as a project in 1993 shortly after NetBSD; and OpenBSD is a fork of NetBSD, but these all are derived from 386/BSD.

Linux versus BSD

BSD: BSD systems are based upon an actual Unix variant called Berkeley Software Distribution, which has a long history.

Linux: Linux is based upon a clone of Unix (Minix), which was far away in functionality in comparison to the above Unix at its time. Terminologically speaking, Linux is only the kernel.

The “Linux-versus-BSD” discussion is very sensitive for some people – they may get very angry about any direction, either in favor of BSD or Linux. It is not a good idea to compare these systems as the whole, but it’s not a bad idea to compare their “usability” in various aspects, for example, as an “office solution”, “desktop solution”, “multimedia solution”, “server solution”, “firewall solution”, etc.

The widespread use of Linux helped some users switch to BSD for good, as various opinions made the issue of “Linux-versus-BSD” visible to public eyes, which made the BSD world appear more attractive.

If we talk in general, we can say that “BSD is much more stable, as it is a REAL Unix” and that “Linux is a very good desktop toy more adapted to users’ needs, as it has more drivers and apps”.

Other global aspect that makes Linux and BSD systems look different is that BSD OS’s have everything under one hood and control. Linux is murky waters because it is not united. For example, you have a DEB (Debian Linux) package – you will not always install it if you use Mandrake or SuSE. A long list of problems ensuing from discrepancies among Linux distros may be written. Linux users surely remember the effort of UnitedLinux, but now it is devoid of life. In the chaos where one Linux system installs with various services and the other one does not, we see that the Linux community is broken as the whole.

Linux is more developed in terms of its accessibility to various types of hardware like, for example, inkjet printers or WiFi USB solutions. But this is because, as I already said, various companies support it. Linux is good for desktop users who want to forget about Microsoft and BSD systems are best as server/router/firewall solutions. Many good administrators say that Linux behaves much worse as server than BSD systems. Something like Red Hat or SuSE Enterprise Server is rather a joke – these systems cost a lot of money. Every good administrator would only bet on BSD or other Internet solutions today. Slackware Linux is exception – it is one of the best.

There are many reasons why BSD systems are less noticeable. The availability of Live CD’s and their easy-to-use presentation is something in which BSD systems lagged behind. You may download Linux ISO images at the drop of a hat. With BSD systems, this is a bit different. You could hardly find a desired BSD Live CD in the 1990’s. Only a few of them do appear now.

OpenBSD

200px-OpenbsdI tackled the problem of building such a CD myself. I toiled with FreeBSD. I succeeded. Later I focused on OpenBSD, as it has a good reputation concerning its solid security structure. I succeeded too. But this would require additional writing and this article is not about making an OpenBSD Live CD; I only want to introduce this system a little and give advice how to make a simple OpenBSD bootable installation CD/DVD, which is also hard to get.

Usability

BSD systems work well with all kinds of standard hardware; however, some users say they are “less user-friendly”. On the other hand, others consider the so-called “user-friendliness” to be a hindrance in making needed configurations. In other systems, where many services run automatically, it is a bit irritating when administrators, with their own security policies in mind, must turn them off on a regular basis after every installation.

OpenBSD could be, from a Linux user’s point of view, a can of worms. Some may disagree with me, but in the world where all mainstream operating systems bet on easiness-to-use and the graphical interactivity, this is surely the case. This means you must forget about graphical installers – your first touch with the system is the text mode. But the text is the best format some people like.

OpenBSD can run Linux binaries on an emulation layer; DOS (and other systems) programs within the Qemu emulator, as well as FreeBSD and other BSD and Unix binaries. Albeit OpenOffice.org has not been ported yet (do you really need such a big bulk of software when there are more handy solutions?), you can easily write or open your MS Word documents in TextMaker for Linux, or in native OpenBSD AbiWord port.

The system and packages

The BSD family of operating systems consists of the base system and packages. The OpenBSD core – its kernel and the base system (system/network utilities, man pages, etc.) get cautiously, if not paranoically audited for security holes.

180px-Bsd_distributions_usage.svgThe OS has a different packaging philosophy in comparison to Linux. It uses ports and prebuilt packages. Ports are fingerprints of applications on your disk. They contain the basic information where they can be downloaded from. You just “cd” somewhere to the hierarchy of the /usr/share/ports directory, where applications are divided by categories; then type “make install” and wait for sources to be downloaded, compiled, and installed.

Prebuilt packages, too, can be installed with a breeze. Unlike RPM archives, which you must install in the consecutive dependency order, here you have everything on tap. And with the command pkg_add -v ftp address and the package name you download everything from the Internet even without specifying the package’s version. This is something most Linux packagers cannot do, only APT (Debian) and its clones.

Installation

The policy of the OpenBSD team is to sell CD’s. Unless you are prepared for a difficult network install, you have two options: either you buy their CD’s, or build them yourself. If you choose the latter option, download the core system from these FTP mirrors: http://www.openbsd.org/ftp.html. Pick out your architecture like AMD64 or i386 and the version (like 4.0, 3.9, etc.). Place all downloaded files in any directory (for example, in /usr/opbsd) and issue the following command to make the ISO image of it:

mkisofs -b cdrom40.fs -c boot.cat -R -v -o /usr/my_openbsd.iso /usr/opbsd

The above command may be used both in Linux and in BSD systems and possibly in any system to which mkisofs is ported.

When ever in the future you are ready to download a newer version of OpenBSD with purpose to make a bootable CD/DVD of it, just change the “cdrom40.fs” in the above mkisofs command (4.0 is the current version of OpenBSD) to the version it agrees with, for example, “cdrom45.fs” (a future OpenBSD), which is a bootable image as the emulated big floppy. A CD or DVD burned with this ISO file will boot on any PC (not DVD in UDF format, but DVD in ISO format).

The following files contain the basic OpenBSD installation – networking, Unix commands, X Window, man pages; not packages like KDE, Aspell, etc.

OpenBSD 4.0 core systemPackages # you can create this directory and put packages in itCKSUM, INSTALL.i386, INSTALL.Linux, MD5, base40.tgz, bsd, bsd.mp, bsd.rd, cd40.iso, cdboot,cdbr, cdemu40.iso, cdrom40.fs, comp40.tgz, etc40.tgz, floppy40.fs, floppyB40.fs, floppyC40.fs, game40.tgz, index.txt, man40.tgz, misc40.tgz, pxeboot, xbase40.tgz, xetc40.tgz, xfont40.tgz, xserv40.tgz, xshare40.tgz

It is important to say that the ISO file cannot be burned to a CD as an ordinary file like an MP3 file – it can be done this way, however, but you will not be able to boot from such a CD/DVD. If you use Windows, the proper way for burning ISO files is to use the “burn image” command in programs like Nero Burning ROM (or “burn ISO” in other programs). Under FreeBSD, you can burn the ISO image with the burncd command (if your CDROM is the master on the second IDE channel; “-s” is for speed):

burncd -f /dev/acd0 -s 4 data my_openbsd.iso fixate

It would be a good idea to make the bootable OpenBSD DVD with packages included in it – just download them and put them to a directory (for example, to a directory “Packages”) where you have your core OpenBSD installation files; then apply the above mkisofs command.

Installation is quite easy. For newbies it is recommended to use a mobile rack and use some older disk (about 3 GB). This is because installing OpenBSD to an already partitioned disk requires a lot of knowledge and if users do not want to bother about numbers of sectors/cylinders and other things they must type in the text wizard, this solution is very handy.

OpenBSD in action

The system boots fast (much faster than Linux). If you selected the X Window environment during the installation text wizard, you only need to run the “xorgcfg” command from the console to configure your X Window environment.

Did you lose yourself somewhere in the text-mode consoles? Use the F5 key (Ctrl+Alt+F5) to get back to the X Window. Are you a complete newbie? Type “man afterboot”. Are you accustomed to Linux and do you prefer a Linux terminal type? After every logon, OpenBSD asks you to type the terminal type you want to use, but the default one – vt220 – does not map keys like you got accustomed to in Linux if you use programs like Midnight Commander (for example, F7 behaves like F6, etc., but not in X). After typing “nxterm” everything should work OK.

A manual text-mode configuration is the absolute preference here. Almost all services are turned off – a first choice for every good administrator, as he will have ultimate control over the whole system. Users, too, may familiarize themselves with Unix and see what is going on under its hood. To run the X Window, just execute the “startx” command. If you want to edit or re-edit the configuration files, peep into the /etc directory with vi as your editor. Do you want to add more packages? Just download them and issue “pkg_add -i package.tgz” command and that’s it!

OpenBSD 4.0 is geared up for most of the network or desktop tasks. After I downloaded some fine MP3 players, I could instantly listen to music. The X Window’s look does not differ from any Unix-like box. VLC or MPlayer multimedia players will help you enjoy all your favorite music or film recordings.

If you have euphoria from seeing the KDE or Gnome Desktop and other apps running smoothly, you may soon become disappointed – OpenBSD has fewer packages than FreeBSD or Linux. For example, running VMware on FreeBSD has been possible for quite a long time; OpenBSD (but not OpenBSD in the VMware environment) requires some smart tweaks to achieve this.

New technologies and automation can also impose a risk

Numerous companies want to earn the highest profit and they introduce various technologies that serve as a marketing competition strategy for most of the time and are often useless. A bluetooth or WiFi technology in your mobile phone brings a security risk when any good hacker can get to your most sensitive data within seconds right from your neighborhood. Most users do not have time to study various security datasheets and they often live happy without knowing they are unprotected. I do not want to say that newer technologies are always nonsensical; however, they deserve pertinent praise only if used on the right place.

If a reader understands this, the mainstream world’s policy is to create the Matrix or a big web of dependencies – if hardware can run in Linux, users use Linux (and possibly buy Red Hat or Xandros).

Numerous “terrific” companies that sell their “amazing security products” forget that using carrier pigeons for communication is by far a more secure solution than any computer communication – an encrypted e-mail, if you are already under suspicion, will always get intercepted, and governments have always enough resources and money to do their job well.

Why BSD or OpenBSD?

Today, when too many companies bring out various distros, it is hard to tell which of them best suits our needs and you may become mixed-up in such a huge list. If companies invest money to a software solution, they may become disappointed if its licensing policy changes. OpenBSD has one sturdy feature above everything – the system and packages are perfectly audited for security holes.

The power of a good policy will make you feel somewhat sheltered from the bad behavior of the world, because you do not have to worry that network services, for example, contain security holes. Something like this often happens with Linux – its websites urge users to download important patches soon after distros are released. With this particular security point OpenBSD as a BSD system stands aside from the usual crowd.

Battle of the Hosting Platforms – Windows Vs Linux Vs Mac
By Justin Knights

Having a web hosting company to host your website is a common thing among webmasters nowadays. The question is which type of platform should you choose? Should you choose the Windows, Linux or Mac? Let’s compare them to see which stands out in the comparison.

The first thing that users compare is the price. Linux is known to be the most affordable among the three platforms. The linux120x120other 2 are more expensive because of the licensing issues because they are owned by Microsoft and Apple. So, by being an open source system, Linux can be obtained without having to pay for anything. Many users turn to Linux because of this reason.

Another sought after feature is the stability of the platform. Again, Linux is known as the most stable platform and is the most suitable to be use as a hosting solution. The BSD system used by Mac is build base form the Unix system. One of the earliest platform types around. This also makes Max a very stable hosting option. As for the Windows, they are less stable and often have problems such as blue screens, freeze and crash. However, Microsoft has made a lot progress throughout the years. Nevertheless, Linux is still the one to turn to when it comes to stability.

Then there is the need to be user friendly. For this, operating platforms need to be simply and easy to use. To be able to use a Linux operating platform, you will need to be equipped with some technical skills because it uses commands similar to DOS systems. Therefore, Linux is more difficult to operate if compared to Windows or Mac. This is because the other 2 systems are using graphical interfaces and this is usually more user friendly. This interface will mostly require users to click and choose according to the administration process displayed on the screen.not-butter-210x130

So, based on the history of the industry, Linux has been the longest platform around but the other 2 systems also has a deep background. The Mac hosting is becoming more popular due to its solid application depending on the scenario. No matter what, all 3 choices could serve you well as long as you are using it for your website. If you are in need of your own server, you will have to choose wisely. In conclusion, with a small price, you can have a good quality platform to operate your website on.

A last piece of advice

Web hosting is a topic that every business owner and web developer has to deal with. I am sure that most of us have been pretty frustrated with shady web hosts and biased hosting reviews. There are sites however, who are dedicated to reviewing and providing information about different web hosts.

TopWebHostReview.net for example, is one of those quality websites that provide nothing but honest web hosting reviews. If you are one of those who needs guidance in term of website hosting, make sure you don’t miss the website. I am sure their unbiased hosting reviews, (for example this one: FatCow Review) will be very helpful.

Milestones in the creation of Linux

+1960s No one can argue that with the introduction of Unix in the 1960s we would not have Linux today. It was originally developed by AT&T employees at Bell Labs

History of UNIX systems

History of UNIX systems

+1983 The GNU project was started with the purpose of creating a free UNIX style operating system consisting of free and open source software (FOSS)

+1980s BSD (Berkeley Software Distribution) was a free operating system project developed from AT&T’s 6th edition of Unix.

+1991 Linus Torvalds realized his terminal emulator based on Minix was turning into an operating system, and this was the makings of today’s Linux kernel

Linus Torvalds

Linus Torvalds

+1992 Linus suggested releasing the kernel under the GNU General Public License. He first announced this decision in the release notes of version 0.12. In the middle of December 1992 he published version 0.99 using the GNU GPL.

Linux and GNU developers worked to integrate GNU components with Linux to make a fully-functional and free operating system. Torvalds has stated, “making Linux GPL’d was definitely the best thing I ever did.”
