Cuo sam da na Linuxu nema virusa? Jeli to istina?

Evo ti cinjenice vezane za linux ;)

Viruses

If your computer shuts itself down without asking you, if strange windows with text you don't understand and all kinds of advertisements appear when you don't ask for them, if emails get sent to all your contacts without your knowing it, then your computer probably has a virus. The main reason for this is because it runs Windows.

Linux hardly has any viruses. And that's not like "Oh well, not very often, you know". That's like "If you've ever heard of a real Linux virus, please tell me". Of course, a Linux virus is not impossible to get. However, Linux makes it very hard for this to happen, for several reasons:

    * Most people use Microsoft Windows, and pirates want to do as much damage (or control) as possible: therefore, they target Windows. But that's not the only reason; the Apache web server (a web server is a program located on a remote computer that sends web pages to your browser when you ask for them), which is open source software, has the biggest market share (against Microsoft's IIS server), but it still suffers from much fewer attacks/flaws than the Microsoft one.
    * Linux uses smart authorization management. In Windows you (and any program you install) usually have the right to do pretty much anything to the system. If you feel like punishing your PC because it just let your precious work disappear, you can go inside the system folder and delete whatever you want: Windows won't complain. Of course, the next time you reboot, trouble begins. But imagine that if you can delete this system stuff, other programs can, too, or just mess it up. Linux doesn't allow that. Every time you request to do something that has to do with the system, an administrator password is required (and if you're not an administrator on this system, you simply can't do it). Viruses can't just go around and delete or modify what they want in the system; they don't have the authorization for that.
    * More eyes make fewer security flaws. Linux is Open source software, which means that any programmer in the world can have a look at the code (the "recipe" of any program), and help out, or just tell other developers "Hey, what if blah blah, isn't this a security flaw?".

Stability

Have you ever lost your precious work because Windows crashed? Do you always shut down your computer the proper way, or do you sometimes just switch it off because Windows has gone crazy and doesn't let you do anything anymore? Have you ever gotten the "blue screen of death" or error messages telling you that the computer needs to be shut down for obscure reasons?

The latest versions of Windows, especially the "Professional" ones are becoming more stable than before. Nevertheless this kind of problem still happens fairly often.

Of course, no operating system is perfect, and people who tell you that theirs can never ever crash are lying. However, some operating systems can be so stable that most users never see their systems crash, even after several years. This is true for Linux. Here's a good way to see this. When a system crashes, it needs to be shut down or restarted. Therefore, if your computer can stay up and running for a long time, no matter how much you use it, then you can say the system is stable. Well, Linux can run for years without needing to be restarted (most internet servers run Linux, and they usually never restart). Of course, with heavy updates, it still needs to be restarted (the proper way). But if you install Linux, and then use your system as much as you want, leaving your computer on all the time, you can go on like that for years without having any trouble.

Most of the time, you won't leave your computer on for such a long time, but this shows how stable Linux is.

Defragmentation(Superior FileSystem):

If you already know what fragmentation is, and are already used to defragmenting your disk every month or so, here is the short version : Linux doesn't need defragmenting.

Now imagine your hard disk is a huge file cabinet, with millions of drawers (thanks to Roberto Di Cosmo for this comparison). Each drawer can only contain a fixed amount of data. Therefore, files that are larger than what such a drawer can contain need to be split up. Some files are so large that they need thousands of drawers. And of course, accessing these files is much easier when the drawers they occupy are close to one another in the file cabinet.

Now imagine you're the owner of this file cabinet, but you don't have time to take care of it, and you want to hire someone to take care of it for you. Two people come for the job, a woman and a man.

    * The man has the following strategy : he just empties the drawers when a file is removed, splits up any new file into smaller pieces the size of a drawer, and randomly stuffs each piece into the first available empty drawer. When you mention that this makes it rather difficult to find all the pieces of a particular file, the response is that a dozen boys must be hired every weekend to put the chest back in order.
    * The woman has a different technique : she keeps track, on a piece of paper, of contiguous empty drawers. When a new file arrives, she searches this list for a sufficiently long row of empty drawers, and this is where the file is placed. In this way, provided there is enough activity, the file cabinet is always tidy.

Without a doubt, you should hire the woman (you should have known it, women are much better organized ). Well, Windows uses the first method ; Linux uses the second one. The more you use Windows, the slower it is to access files ; the more you use Linux, the faster it is. The choice is up to you!

Doesn't slow down

Windows has a number of design flaws, resulting in it becoming slower and slower and not lasting very long. You've probably heard more than once someone say "My computer is getting sluggish, I'm gonna reinstall". Reinstalling Windows solves the problem... until next time.

You may think this is just how computers work: they're very new technology, and not really stable yet. Well, try Linux and you'll be surprised. Five years from now, your system will be just as fast and responsive as the day you installed it, not to mention that you won't have any viruses, adwares, trojans, worms, etc., that would force you to reinstall anyway.

I have managed to convince many people to switch to Linux, while keeping Windows on their hard disk, because they needed to use some piece of software that Linux doesn't have (eg Autocad), so they use both systems. Since the day they switched, most of them have reinstalled Windows about once in a year or two; but Linux didn't let them down, and is still running perfectly well and is still snappy today.

Linux lets you spend more time working, less time reinstalling over and over again.

Less chance of backoderd software.

The difference between "closed source" (proprietary) and "open source" software is (how did you guess?) that their "source" is open. Huh, okay, why do I care? Well, the "source", or "source code", is like the secret recipe of every software, like the recipe of a cake. When you buy a cake, there's no way you can figure out the exact recipe (although you can guess bits and pieces, "there's some coconut in here"). If a bakery gave out the recipe for its super-sucessful cheesecake, it would soon go out of business because people would bake it for themselves, at home, and stop buying it. Likewise, Microsoft does not give out the recipe, or "source code", of their software, like Windows, and rightly so because that's what they make their money from.

The problem is they can put whatever they want in their recipe, without us knowing. If they want to add a bit of code saying "every 12th of the month, if the computer is online, create a list of all the files that have been downloaded in this computer since last month, and send it back to Microsoft through the network". Microsoft probably doesn't do that, but how would you know, since everything is closed, invisible, secret?

A little while ago (October 2008) a lot of Chinese Windows users (most of them buy pirated copies of Windows) saw something strange happen with their computer: every hour, their screen would go black for a few seconds. Nothing to really prevent you from working, but it can easily make you go nuts. Microsoft had added a bit of code (an ingredient to the recipe) saying "if this is detected as a pirated copy of Windows, make the screen black for a few seconds, every hour". Now the point is not that the software was pirated: pirating software is bad, period. The point is that these users got an automatic update for Windows (updates usually fix bugs and add new features) without knowing how it would affect their system. No one knew.

Changing the source code of open source software is a much more open process. By definition, all the recipes are public. It doesn't matter to you since you won't be able to understand the code anyway, but people who understand it can read it, and speak out. And they often do. Every time someone wants to change the source code, all other developers are able to see the change ("hey man, why did you add this code spying on the user's keyboard input, are you out of your mind?"). And even if the whole team of maintainers for a piece of software go crazy and start adding puppy-killing features all over their source code, someone outside the team can very well take the code, remove all the bad bits, create a whole new version of it, and let the world know what the difference is. It's open.

That's why you can be sure open source software doesn't do bad things behind your back: the community keeps a close eye on all the recipes.

Rebooting:

Have you just upgraded one or two little things on your Windows system with "Windows update"? Please reboot. Have you just installed some new software? Please reboot. Does your system seem unstable? Try to reboot, everything will probably work better after that.

Windows always asks you to restart your computer, and that can be annoying (maybe you happen to have a long download going on, and you don't want to interrupt it just because you updated a few pieces of your system). But even if you click "Restart later", Windows still keeps bothering you every ten minutes to let you know that you really should restart the computer. And if you happen to be away from your computer and you didn't see the question, it will happily reboot automatically. Bye bye long download.

Linux basically doesn't need to restart. Whether you install new software (even very big programs) or perform routine upgrades for your system, you will not be asked to restart the computer. It is only necessary when a part from the heart of the system has been updated, and that only happens once every several weeks.

Do you know Internet servers? They're the big computers that answer you when you ask for a web page, and send the information to your browser. Most of them run Linux, and since they need to always be available (a visitor could come anytime), they aren't restarted very often (services aren't available while the system is starting). Actually, many of them haven't restarted for several years. Linux is stable, it runs perfectly well without restarting all the time.

You'll probably not let your computer stay on for several weeks but the point is: the system won't bother you with restarting all the time.

Koji ti koristis ako se smije znati. 

Volio bih da cujem misljenje nekoga ko je koristio ovaj OS (tj. iz prve ruke    )

Moze li se igrati cod2 na Linux-u?

Jeli ima vise verzija poput windows home, pro, xp, 7,... i koja je najbolja?

PS: sta je ovaj Ubuntu?

PS2: thx 

[Zver]

Ja sam nekoliko meseci koristio prethodnu verziju ubuntu linuxa, u virtual machine, moze da se igra cod2 kada sam zadnji put proveravao preko programa WINE hq, ali PB ne radi, tako da mozes da zaboravis online igranje.

Samo online i igram. 

Kako ti se pokazao? Jeli istina ovo za viruse?
Jeli moguce imati dva OS na istom HDD-u? Recimo Windows na C particiji, a Ubuntu na D particiji.

Vec smo pricali o tome zlenzlla ^^
Mozes i 10 sistema da instaliras ali samo jedan da ti bude dignut u tom casu.

[zlenzlla]

Ko ce mene ispraviti nego sparta. 

Znam da je negdje spominjano, ali me ubij ne znam gdje.

[Zver]

Nisi u pravu spartanac, jacaanjem procesorske moci i padanjem cena memorije, virtuelizacija je dosla i na desktop racunare, tako da lepo napravis virtual masine u VM ware npr, u virtual machine instaliras koji god zelis OS, dodelis mu koliko hoces rama, i hdd prostora, i lepo vrtis drugi os u prozoru (ili u full screenu kako god zelis), sam OS u vmware ne zna da se nalazi na virtuelnoj masini i ponasa se potpuno normalno, tako da mozes imati vise sistema pokrenutih u isto vreme i da rade razlicite taskove.

mislim da smo vec pricali o ovome... da secam se da si to spomenuo, ali mi se ne cini kao najbojle resenje. To moze extra da uspori komp, o igricama necu ni da pricam.

Stavis MNOGO rama (kupis core i7 i plocu (one podrzavaju do 24 gb rama)) npr 16 gb, i opusteno mozes da furas sta god hoces bez ikakvih vidnih usporenja (bilo bi dobro i dedicated hdd da imas), ali virtuelizacija je super stvar, i MNOGO JE PRAKTICNO iako mozda tako ne zvuci.

Znaci da kod mene nema nikakve sanse na ovom racunaru za tim (athlon 64 3000+ koji radi na 2.2 GHz, 1 GB DDR RAM, AsRock 939s56-M ploca). Ma meni je bitno da mi OS radi dobro i da ga ne moram reinstalirati svako malo. Ove godine sam Windows reinstalirao jedno pet puta, a moram opet. Zato sam mislio da instaliram na drugu particiju Linux pa po potrebi da ih mijenjam.
