How do I run Steam games on Linux?

Q. I got Steam to work on Linux using Wine. All my games worked just fine for a while, but all of the sudden none of them will run (except Portal for some reason). When i try to open them it says, "Preparing to launch," then does nothing. Does anyone know what the problem is, or how to fix it?

A. You could use a program like WINE (Windows Emulator) to get it going. Or you can try a virtual machine but sometimes that wont load drivers and you still wont be able to play. The best option will be a dual boot of windows and linux. The reason being, that for the sake of stability, for the drivers to work, and for you to get a good performance it is just easier to play on Windows (since all PC games are generally designed for Windows environments).

How can i play COD MW2 on Linux Ubuntu?
Q. So i bought MW2 and installed steam on linux and then installed the game... after it finished, i launch the game and it opens but with a dark screen and the words seem to be corrupted , like they do not appear and i cant do anything with it... how can i play MW2 on my computer, although i have Wine and the game opens through it already,,, what should i do?

Thanks in Advance,
Adam.
i did install wine from before... and i dont know how to open the game in window mode , can you please tell me how?

A. Try using PlayOnLinux. It will configure Wine automatically for COD MW2.

How can i Install steam on ubuntu os and make it work?

What is the difference between Windows and Linux Servers?

Q. In not too technical terms - what is the difference between thse two? If I were to use .net nuke , is there a perference over which server I should use?

A. Wow! This is a question that pops up all over the web, and one that I had myself as a web services person. You can read a lot about the differences - as well as the advantages of one over the other. In the sources area, I've listed several such discussions and articles, including the last item which is a lengthy discussion in a Wikipedia article on the subject. In terms of finding something non-technical, I would recommend the first site.

The article from AskWebHosting.com states the following about using .net: "If you intend to create your site using ASP, FrontPage, the .NET environment, Windows Streaming Media, Access, MSSQL, or any of the other Microsoft proprietary technologies then you probably need to use a Windows host. There is limited support for a number of these technologies in Linux, but they can be expensive and are usually lacking in features."

But you're talking about using DotNetNuke, which is an open source answer to .NET. As such, it may not matter at all, from that standpoint, which option you choose.

I hope that these sources are helpful!

What is the common place to mount a network drive in linux.?
Q. I have a Ubuntu server that I hope to use to share files to my roommates using Samba. I know I can mount the drive anywhere and then share it but is there a common place that it shold be mounted?

A. With Ubuntu most drives (other than the obvious /, /boot, /home, etc.) are mounted under /media, but it really doesn't matter.

Playstation 3 as a Media Center Extender, how can it read my networked external hard drive?
Q. I use my PS3 as a media extender. However it only reads the pictures, music and movies in my documents in Vista Home Premium. I have a Network attached storage unit with Gigs of music, movies and pictures.How can I get my PS3 to read those files without having them stored locally on my computer. Or even if there is a unit that can do that. Thank you in advanced.

A. There are a couple of things you can do:
* Set up a UPnP (universal plug and play) server on your computer that will be detected by your PS3 (this is what I do)
* Move all those files to a USB Drive then plug that into your PS3 (this will remove the files from your computer but not take up all the space on your PS3, plus you can get cheap USB drives with lots of space (300GB+) now days)
* Look into getting a file server for both your PS3 and Computer. A small Linux box would work best for this and they have models on ThinkGeek.com

Is it safe to have two different antivirus programs; one for your home computer and one for your flash drive?

Q. So my question's just that. I've learned that it's bad to have more than one antivirus program running on a single computer, but I was wondering, is it okay to one antivirus for my actual at-home computer, and a separate antivirus for the flash drive/portable device? Please and thank you.

I currently have avast! for my home computer and I'm thinking of getting ClamWin for the flash drive.

A. You need to get one antivirus program, one firewall and some spyware/adware/malware removers if you don't have it.
I use Norton Internet Security (antivirus, spyware, firewall, add blocker, mail spamfilter, pop up blocker etc) Ad Aware, Spybot and more on my desktop running XP Home SP2 with Firefox and Yahoo Toolbar with pop up blocker.
On my laptop i have Ubuntu 7.04. No security needed in Linux, but i use antivirus and firewall. Firefox is standard.
I have no virus, spyware, adware, pop ups etc on my computers.
Mozilla Firefox and Opera are safer browsers to use then Internet Explorer.
http://en-us.www.mozilla.com/en-US/produ...
http://www.opera.com/

Here are some free programs.
BitDefender Anti-Virus Free.

Q. I know some of u are thinking,why do u want a antivirus for linux, well i read that i can still get a virus so i just want to make sure i don't even get one! so give me the best of the best !! free antivirus please!!!

A. Avast and AVG are both great, both free and both should have linux versions. As the other poster said, you probably won't need one, but having one won't hurt at all (besides, they're free).

What is the best Linux distribution for an avid Windows users that can be downloaded on my computer?

Q. I am looking for Linux Distribution that is the best one for the avid Windows User that can be downloaded and installed directly on my computer. I do not know how to burn ISO files, plus I need something fast and easy.

A. Ok you can see some distributions of linux here
http://helplinux.altervista.org/english/generico/view.php?arg=26&titolo=Distros%20list%20of%20linux&desc=a%20lot%20of%20distribution%20of%20linux

What is the best linux distribution for an older computer?
Q. Which linux distribution would be the best to install on a older computer that still woks fine, like: 866mhz, 512ram, 80GB hard drive?
I mean, so I can reuse an older computer for basic tasks such as browsing the web, writing documents, store some music and pictures.

A. Something like Ubuntu or Debian would work fine.

http://www.ubuntu.com/products/WhatIsUbuntu/desktopedition
http://www.debian.org/

Gnome is another popular choice:
http://www.gnome.org/

Puppy Linix runs only in RAM, that might be a good choice for an older computer with a slower processor:
http://www.puppylinux.org/

Another good distro for a slower computer is VectorLinux. I have seen it run on much slower PC's than yours:
http://vectorlinux.com

What Linux Distribution should I put on my other hard drive partion?
Q. I have to hard drive partions, with one partion being Windows XP, and the other getting ready for Linux. I am wondering what Linux distribution I should use. The computer I use is for Home use, like homework, web browsing, ect... Any suggestions?

A. I thoroughly recommend Linux Mint 7 Main Edition which is built upon Ubuntu 9.04 Its easy to install and easy to use plus it comes with much of the software you are likely to need preinstalled

The Perfect Desktop - Linux Mint 7 (Gloria)
http://www.howtoforge.com/the-perfect-desktop-linux-mint-7-gloria

You download the ISO. image of Linux Mint 7 then you need to create a Bootable LiveCD for installation

Linux Mint 7 can also be run direct from the LiveCD from Booting up without touching your Hard Drive

INSTALL LINUX MINT WITHIN WINDOWS

Linux Mint has a feature called mint4win based on the Wubi installer (Ubuntu) http://wubi-installer.org/ which enables you to install Linux Mint within windows (Windows 7 run mint4win in vista compatability mode)

You keep Windows as it is, mint4win only adds an extra option to boot into Linux Mint. mint4win does not require you to modify the partitions of your PC, or to use a different bootloader, and does not install special drivers. It works just like any other application.

mint4win like Wubi keeps most of the files in one folder, and if you do not like it, you can simply uninstall it as any other application.

Boot in to windows insert the LiveCD you have just created and you will offered the option of installing inside windows which is where mint4win comes in, you will be asked how many gigabytes you wish to allocate to Linux Mint (I recommend 8gb) then you set a password for your installation then click install and thats it.

Once Linux Mint is fully installed upon starting your PC you will be given a choice of which operating system you want to use Windows or Linux Mint

Using a virtual connection to Linux terminal, how can I open the Linux text editor?

Q. I'm virtually connected to a linux terminal. In the terminal window I type the following commands
tcsh
cd vlsi1/Lab3
ls
pico TxFIFOtest
(these commands open an editor inside the terminal, the editor is terrible though and I will be making numerous changes to this. Is there a way to open this with a text editor?)

A. u are using tc shell?

any shell have ENV values, editor are en ENV key for linux editor, in debian/venenux the editor by default are nano or mcedit-debian, the first acts as normal ecitor like MSDOS, the second atc as special editor using IBM's F1 to F12 keys

install vim (not vi) and cam note diference, also can install nano, nano its more for ignorant command line real linux users

if u wish use graphical editor only use sux (venenux and sidux only) or install sux (apt-get install sux) and ejecute graphical editor as: "sux kwrite" or "sux leafpad" when runs, sux ask for root admin password (or for user password if u are in sudoers file)

i recomend install linux venenux+massenkoh plugs due u seems to be a non linux user, ubuntu are not good choice for system training

How to use the paste command in Linux terminal?
Q. What should i do before i use the paste command in linux terminal.Give me an example.How will u use the command paste?

What Linux app will allow you to view a webcam from a windows user?
Q. Me and my boyfriend are trying to see my cam. He has Linux though and I run on through Windows. What can he download to be able to see my camera?

A. I would suggest doing a little bit of research on the model of web cam, as you can usually find some step by step tutorials for how to use the camera in Linux.

For example, I have an old Linksys camera and I can use VLC to use it, as well as a few other commands which I found when I searched for the name of the camera and the type of Linux I was using.

How to remove "linux mint" from my Win7 GRUB screen?
Q. I recently ran linux mint form a usb drive, but I decided that I don't like it. Ever since, as soon as I power on my computer, I have to choose to boot into Windows 7 or Linux mint. Some tutorials I saw required a repair disk to boot into command prompt, which I don't have. Any advice would be greatly appreciated.

A. What you need to do is rebuild the BCD Store.
That is where that message is coming from.
It is sort of the new and improved bootloader starting
AFTER XP.
That can be a complex process, so lets go at this the
way you already were.

EVERY Win7 system will allow you you to make a "Win7 Repair Disk".
Note it is only for repairs, very important ones, (but somewhat small repairs.)

Please see the following MS link about getting this VERY helpful disk
(while the computer is working...)

Can I run an antivirus on windows installed on a mac?

Q. I am soon to be getting a macbook, and I plan to run a dual-boot system on it. My question is whether it is safe to install an antivirus on windows, like nod32 while having an antivirus on osX as well. I know that intalling more than one antivirus is a very bad idea, I am wondering if that is true for two operating systems on the same machine.

A. why even dual boot --unless u have a large hdd---just use linux from a pen drive --it is an open source an is safer then windows --it's a plug and play OS----i use it in travel --it's great for cafes and airports --plug in log on lo gout put pen drive in ur pocket

Would any antivirus program prevent that fake antivirus software?
Q. I just had it and had to set my dell laptop a month before so it'd go away. Would any antivirus program from windows prevent this? If not how can I prevent that fake software crap?! Thanks!

A. Hi There,

Do not click on any of the links when the pop up comes up. Not even the "X" that is supposed to close the pop up. When you click on any choice that "accepts" the download and installation.
Just hit the back button to go to another page or shutdown your browser and clear any personal data.

To minimize the problem set up a guest account (without any privileges) for you web surfing.
Then nothing is supposed to run or change your computer (need admin priviliges for that)

Another sure way would be to do your web surfing using a Linux live CD to prevent any of the fake programs from loading. When you use a live CD everything runs in RAM so when you shutdown everything is gone forever. You can download and burn a live CD or order a free one (takes about two weeks to arrive).

Hope this helps,
Al

What exactly is so great about linux?
Q. I have tried Ubuntu out once but I didn't really see the point of it and I ended up going back to windows 7. What does linux have to offer that windows does not (apart from the fact that its free)? I'd really love to learn more about linux and play around with it (especially customizing it and tweaking settings to personal preference but I don't know if that's what it's about).
Oh and can someone also please recommend a (or perhaps a few) versions I should try out?

A. I'm so glad you ask this question!
Well, linux is great from many points of view. I hope you take your time reading this, and I hope this will prove helpful to you! :D

1. The main one, which is definitely the best thing for an every-day user is the fact that Linux is virus-free. No antivirus, no problems at all with malwares or malicious software.

2. Open source. Open source doesn't mean ONLY that it's free. Aside of the fact that you have FREE licensed OS, there is a huge open source community, constantly working on your linux version (we call them distributions), fixing bugs, or dangerous leaks and making it better, and better every day. With linux, you will always benefit from the latest updates, which is great.

3. Great security. Having no viruses, being open source (constantly updated), with Linux you can be sure you're system is as secure as it can be. As for myself, I feel secure ONLY on Linux.

4. Optimal. Linux is, no doubt, optimal! It is very fast, even on slower computers. As an example, at the Informatics Olympiads in my country, they test the sources both on Windows and Linux, and Linux is faster all the times, sometimes even twice. Linux is faster because of it's relative simplicity, because of it doesn't have all those additional programs which Windows needs for pretty much everything to slow down your computer.

5. Support for all standard formats. With Linux, you are off to go from the moment you install it. It supports pretty much EVERY standard format there is. In windows, to emulate an .iso you need a program (in Linux you don't; of course you can install, if you want a nice user interface), In windows to unzip a .zip you need a program (in Linux, you don't) etc. etc.

6. Great control over your OS. In Linux you got the Terminal, which allows you to do EVERYTHING you want (including to screw up your computer, believe me :)) ). Basically, in Linux you control the system. In Windows it's different, Windows is a closed box, you can only see it's outside. You are forced to use what they give you, how they give it to you. In Linux you can use what you want, how you want. And that's nice.

7. Just like the OS, you benefit from a lot of open source software, which (some of them) are great! Like GIMP instead of Photoshop, Blender instead of... well instead of nothing because Blender is the best out there for 3D Modelling (IMO)..., Inkscape for vector graphics etc.

8. WINE. If you still need a certain program from Windows which doesn't have a version for Linux, there is WINE. WINE is basically a thing which lets you install and run Windows programs as your Linux would be Windows. You can very well install MSOffice, Photoshop, Dreamweaver, anything you want. Even games! Yes, you can play windows games on linux with WINE. For some of them, you may get even better performance than on Windows itself. With a little bit of learning it's ropes WINE will make you forget about windows.

9. Customization! That's another great thing of Linux. On Linux you can customize, tweak, modify anything at your pleasure, given that you know how to do it. Of course, some of the things you can customize easily, some of them harder, but there's always that feel of happiness when you make your system look like you want to. And when you know you did it!

At first, I would suggest you to use a dual boot: Windows 7 and Linux, so that you can switch to Windows whenever you need, until you get familiarized with linux. For this, it is necessary to install Windows first, and then Linux with it's bootloader so that it recognizes both Windows and Linux at boot.

Finally, as you requested, here are some versions (distributions, like I said, or shorter distros):
1. Ubuntu - it is great, user friendly. If you want full customization you should try older versions of Ubuntu, like 10.10 or 11.04. http://ubuntu.com/

2. Linux Mint 12 - the distro I'm using now. It's as great as Ubuntu, if not greater. It's interface is very very nice, and I love it. http://linuxmint.com/

Have a nice day, and good luck on learning the ropes to this great system, Linux!
I hope I helped!

Will a Linux operating system be difficult for somebody who used only Windows all life?

Q. Today I decided that I am officially tired with Windows and want to install Linux on my laptop. I read on a website all the pro and cons of each operating system ( Windows, OS, Linux) and discovered that Linux is the only one who had the pro list longer than the cons list. ( windows too vulnerable and Macs too pricey). In any case,in the Linux cons list it said that Linux should only be used by experienced computer users. I know my way around a computer but I cannot call myself and expert. Would it be difficult to transition from Windows to Linux if I am not a computer expert?

A. Welcome to the would of Linux based OSs!!

At one point or another most Linux users made that switch, and it can be difficult IF you try to use Linux (remember Linux is the kernel not the OS) like you use Windows. There is a learning curve that you must overcome. Things are just different, but not difficult. Years ago it was harder, but now, there are many distros (distributions) tailored to new users.

Since you already know the pros and cons, there is no need to discuss them. But when you start using Linux based OSs, you WILL be in "windows mode". This just takes time to overcome. Most people that tried Linux and said it was to hard, did not give themselves enough time to get out of "winblos mode".

When you install a Linux distro, you do not need antivirus, antimalware, firewalls, you do not need to defrag. You can install them if you like, but there is no real need unless it makes you feel better. If you stick to the repos (repositories - just to make it easier to explain - you can think of it like an app store that you use on your phone) you will be safe from malware.

Now the hardest part, at least for me, is to choose which distro. Go to distrowatch.com for info on hundreds of different distros.

Most distros are based on a few main distros. Here is an image to give you an idea how many forked from other distros:
http://files.cyberciti.biz/uploads/tips/2007/06/44218-linuxdistrotimeline-7.2.png

When I made the switch from winblows to Linux, here was my criteria:
1. made for beginners - you will have many problems if you jump to a distro made for experts
2. it must be a popular distro - the more people using it, the more help you will receive. you can ask on YA, in a linux forum, or people you know.
3 must look decent. I just don't like an ugly desktop.

Also, you can take almost any distro and add different desktop environments. You can think of the DE as the user interface. You can take Ubuntu, that ships with the Unity DE, and ad another, say KDE. But they do have this already, and called Kubuntu.

You can take Mint (which I recommend for new users) which you can choose form Cinnamon, GNOME, KDE, MATE, Xfce desktops. Or you can add others. Here is a gallery of some of the DEs:
https://en.wikipedia.org/wiki/Desktop_environment#Gallery

So I would suggest to get an 8 or larger USB flash drive (or what ever you have) and use a program called YUMI to install as many different distros on that drive as it can hold. You choose which distro to boot into on start up. This way you can try out many different distros.

Also try out many of the different DEs. There is no way to know which one is right for you. since they are personal choice. I recommend the KDE since you are coming from winblows. It is pretty and (to me) easier to use. So I recommend Mint with KDE.

There are other made for beginners. If you decide to use Ubuntu make sure that you have a wired internet connection when you install. Ubuntu does not use closed source or proprietary software (it a FOSS thing). It will ask when you install if you want to use restricted software. Mint ships with this software and works better out of the box.

There are distros made for just about anything. If you have an older computer, there are distros for old computers. If this is the case I suggest to not use KDE but one made for older or slower computers. Like LXDE (You can download Mint with LXDE). There are distros for media production, scientists, educators, security, privacy, embedded, etc.... Heck, you can even put Linux on your router, mp3 player, tv, and other devices.

Here are some others:

How to remove linux from desktop computer using xp cd?
Q. I am using linux in my computer and do not like it and i want to remove it but i have no idea and i only have xp cd tell the full step.

A. HI There,

I had the same experience using LInux and decided to switch back to XP. Many of the applications I used simply did not work with LInux. Also configuring the printer, scanner (and wireless adapter) were difficult or even impossible. Not Linux's fault but the manufacturers did not include drivers for LInux.

It is not difficult to install XP and it only takes about 40 minutes or so for the installation. After installing there will be about 80 updates from Microsoft which will take longer than the install. If you have the original XP then you will want to update to SP-2 and then update to SP-3 since SP-3 is the only version still supported.

Before installing I like to write down the 25 digit key code on the tag located on the CD ( use big letters and numbers to make it easy to read later ).

Also write down all the settings needed to connect to the internet. Once XP is installed they will no longer be available.

Another thing to do is decide upon which antivirus app you want to install and have the CD or file ready on a flash drive ready for when you connect to the internet. At the very least have the URL written down so you can install ASAP. It only takes a few minutes for an unprotected system to be infected by a virus. The first thing to do after connectingto the interent is to install your antivirus and make sure the firewall is enabled.

Now you are ready to install XP.

To install all you need to do is insert your XP CD/DVD into the optical drive and boot from it then follow the instructions.

You will be asked for your time zone , keyboard configuration, password for admin account and at some time you need to enter the 25 digit COA that you have written down.

You do not need to enter a password (just press <Enter> with the dialog box blank or if you want a password; go ahead and enter it (write it down and save in a safe place). I don't use a password but if you do make sure to remember it .

To boot from the optical drive restart your computer and watch the monitor. It will show the memory and hardware check and at the bottom of the screen it will tell you which key to press to change the boot order. Probably <F12>, <F8>, <Esc> or <Delete>.

As soon as that message appears; press the key and it should boot from the CD/DVD.
If you are not quick enough; shut down and try again.

Once the computer has booted from the CD/DVD drive just follow the instructions for a full installation.
This will format the hard drive and install XP to the entire C-Drive. Formatting will erase Linux and set up the drive for Windows XP.

After the installation has finished you will need to reboot and you will be running Windows XP.
First go into security settings and enable the firewall.
Second setup your internet and connect to the internet. Immediately install your antivirus and let it update. Your antivirus may want to do a full system scan as part of the installation. That's OK.

After the antivirus is running Windows will want to update. If it does not ask then go to the Microsoft website and find updates and install them.

Good luck,
Al

Q. I just bought a Macbook Pro and I run Frostwire and I don't have antivirus to protect my Mac. I am new to Apple so I hardly know anything about this yet, so any help with be great, Thanks.

A. clamav is a good antivirus program that has long existed for linux and since the macos is now based on bsd which is a very very similar os to linux, there is a version of clamav for mac too. Im not a mac user so beyond knowing about it, i don't know much about any others.

edit - Actually, there is a very good reason to have virus protection on a mac. Even though most viruses can't run on macs, it doesn't mean they can't be there and transferred to a pc and infect that pc. He says he is downloading stuff using a p2p network and that tends to be one of the most common ways viruses are spread so it is only prudent to have an antivirus program that can scan the downloaded files and clean them up if needed.

Is it safe to have two different antivirus programs; one for your home computer and one for your flash drive?

Q. So my question's just that. I've learned that it's bad to have more than one antivirus program running on a single computer, but I was wondering, is it okay to one antivirus for my actual at-home computer, and a separate antivirus for the flash drive/portable device? Please and thank you.

I currently have avast! for my home computer and I'm thinking of getting ClamWin for the flash drive.

A. You need to get one antivirus program, one firewall and some spyware/adware/malware removers if you don't have it.
I use Norton Internet Security (antivirus, spyware, firewall, add blocker, mail spamfilter, pop up blocker etc) Ad Aware, Spybot and more on my desktop running XP Home SP2 with Firefox and Yahoo Toolbar with pop up blocker.
On my laptop i have Ubuntu 7.04. No security needed in Linux, but i use antivirus and firewall. Firefox is standard.
I have no virus, spyware, adware, pop ups etc on my computers.
Mozilla Firefox and Opera are safer browsers to use then Internet Explorer.

where can i get a free operating system for an old laptop?

Q. I have a Toshiba Tecra 730XCDT from round about 1995 and i want to download a free operating system for it. i don't care whether it's text-based or GUI but it needs to fit on a 3.5" floppy.

A. your best option would be a VERY small BSD install or an equally small Linux install. you may even wish to try Minix
Google it!

downloaded an operating system from university how do i burn it onto a dvd and install it on the computer?
Q. The university where I teach offers free operating systems for the computers that are bought from them, I bought one such computer, it came with no operating system installed. I downloaded it onto this computer (as instructed) and i was wondering how to burn it and install it on my new computer, Thanks.
As I said if you read the whole question it is OFFERED for FREE by the school since I teach there.

A. What extension does the downloaded file have, my friend? If it's an .iso file you can use a FREE ISO Burner program, such as ImgBurn.

Once the program has been installed, you can right-click on the .iso file and select to burn it ... or open it with ... dependent on which Operating System your computer is running.

Do you know which Operating System the university have allowed you to download, my friend? I ask this as Windows XP and earlier would only require you to burn to CD disc, whereas Windows Vista and Windows 7 require a DVD disc. You can get an idea of which size disc you will require by looking at the properties of the file that you have. If it's under 700 MB in size it will fit onto a CD disc. Larger than this means that you'll need a DVD disc. (Various different distributions of Linux depend on what, exactly, is included in that distribution. Some will fit on a CD and other will require a DVD.)

what is the besst free operating system for a windows user?
Q. I have a new compter and I don't have money to buy windows so I need a free operating system.
I'm used to windows .
I tried linux but it's diffrent from windows in so many ways.
and I bought a used computer that the owners erased the hard disc.

A. Ubuntu Linux ( http://www.ubuntu.com ) or gOS ( http://www.thinkgos.com/ )

How would I randomize a VERY LARGE text file?

Q. As the title suggest, I'm looking to randomize a massive text file, in the upwards of 3gb. This goes beyond the processing power of programs such as Notepad++ and also TextPipe Pro. I work with very large lists like this often and have yet to find a solution. Does anyone have suggestions?

A. Not sure what you mean by randomize.
In Linux in Perl etc. you could just allocate a good chunk of swap memory and let it chug away. I
had a LaTeX2HTML process years ago that ran fine in more memory than I had RAM.

Heck, 3Gb isn't that much RAM nowadays so you don't even need that. If you wanted to randomize 3Tb it might take a bit more thought.

If it's something you do often, then maybe it's worth spending a bit of time on. Better algorithms beat faster computers hands-down. We get so lazy nowadays - just buy a new computer instead of tuning programs and doing digital liposuction (removing the fat).

Linux users if I use a CD that came with a book to install linux and it is missing programs?
Q. Like let's say movie player, or music player, or simple things like calculator, or some sort of notepad. Where can I download them that will work with linux?

A. Linux will generally have a program like Software Center or Synaptic to install the files from their repositories. You open this and type in a search for what you may not have, check the file and click apply and it will install the software for you. There isn't any reason to be doing terminal commands unless it is a file that is not in the repository and to install from the terminal, you must be logged in as root, not user. Most versions of Linux disable the root account to prevent people from messing the operating system up. Some of what you have mentioned are part of the install for the desktop environment being used and don't need to be installed by the user. You can always download a Linux LiveCD and run it in memory to see if it is what you want to install.

How to remove an OS from a multiboot?
Q. For a while now I've been running Windows 7 in a multiboot with Vista and Linux Mint. I'd like to get rid of Vista while keeping a Mint/Win7 dual boot. Is there a way to do this?

A. Depends on which OS is controlling the boot menu. If it is Windows, you will find a text file in the root of your computer called boot.ini. Open it in notepad and you will see the menu options. Remove the line for Vista and resave the file. (Back up the old first just in case...)

I do not know if Win 7 as the option, but with early versions of Windows you can edit the boot.ini using msconfig. Start > Run > type in: msconfig

Go to the boot.ini tab

Run the "check all paths" and it will update the boot.ini to reflect the current configuration of your computer.

What's the best software to make simple 3d images ?

What is the program language used to make the ipod softwares?
Q. I know that, there is linux softwares for ipod and a lot of hacking that is really usefull but, i need to know what is language used to make a regular program to ipod. Like if I'm going to program a website I can use PHP or ASP, or if I'll program to windows I can use visual Basic or C++. Thanks!

A. Most projects in Linux are done in C especially if its related to the OS. Only recently has C++ become part of the OS.

iPodLinux creates it own operating system and stores it on the iPod. It would very likely be written in C.

How do i switch web browsers if im using linux?
Q. My browser is currently bing (its horrible) But i don't know how to switch it i checked tools for internet options but its not there im currently using the latest linux Software.

A. As stated directly above me, Bing is not a browser, it's a search engine. To change that, you would need into the about:config in firefox and change the search engine, you can find tutorials through google(Which I recommend). As for browsers, I assume you are using Ubuntu. If so, simply "apt-get install browserpackagename" Replacing browserpackagename with the package name of the browser, of course. You may need sudo to do so, if not, go root with "sudo -i", I believe. To uninstall a browser do the same, except "apt-get remove"

How to use a crossover cable between two computers?
Q. I have two Ubuntu Linux computers and a crossover cable.....What do I do? I just want to be able to share files between computers.

A. Set the IP addresses on both computers to be within one sub network like

pc1 ip - > 192.168.0.2
pc1 mask -> 255.255.255.0

pc2 ip - > 192.168.0.3
pc2 mask -> 255.255.255.0

After that you must share at least one resource on one of the pc's

After that you should be able to access the shared resource from the other computer

Is it possible to link multiple linux based computers in a network into one to form one powerful computer?
Q. I heard a while ago that you can actually link multiple linux based computers together to form one powerful one. Any ideas?

A. Clustering / Cloud computing is not an easy task - but it's achievable.
It also depends on what the task you want to achieve. Clustering is usually done to batch huge processing jobs that would otherwise take weeks or months.

Some examples:
Render farms - thousands of linux processing computers rendering 3D images to form a movie (think Shrek or the like)

Compile farms - same, but used to compile huge applications - like video games. usually dist-cc is used.

If you simply want a "super computer", then this isn't the way to go.

When is Google going to release a real version of Chrome OS?

Q. Not Chrome OS Linux, or from Hexxah, but from Google itself. So far you can only get it if you buy a Chromebook. When is Google going to let us buy a cd or download it? Nothing else is working for me, but Joli OS is a close second.

A. I don't think they will because they want people to buy Chromebooks "...the way you will get Google Chrome OS is by buying a Chromebook that has Google Chrome OS installed by the OEM." http://www.chromium.org/chromium-os/chromium-os-faq but you can also try EasyPeasy http://www.geteasypeasy.com/

What do you think are the advantages and disadvantages to a computer buyer when using one of the?
Q. free operating systems such as google chrome or linux rather than using windows?

A. Windows - people are more accostmed to using windows, it is the business preferred OS.
Linux - Ubuntu - less then user friendly to configure and setup, but stable.
Chrome - new, never used it myself, can't make any suggestions on it....

How do I block websites on my computer?
Q. I use Google Chrome. On a linux machine, though I doubt that's relevant.

This ear I am taking 8 different senior highschool courses, and I have a habit of aimlessly looking for funny things on the internet. I need to block my favorite websites until I'm in good habits. Like putting a padlock on the fridge when you know your weakness.

A. First of all âhostsâ is the name of the file not the folder. Please refer to the screenshot above.

Ok, letâs start from the first step. When you typed
notepad %windir%\system32\drivers\etc\hosts in the run command, were you not able to see the file named âhostsâ getting opened in notepad?

If not, then copy the hosts file from other computer to your targeted computer at the location %windir%\system32\drivers\etc

Minecraft launcher wont download on Macbook?
Q. When my mom upgraded my computer to Mountain Lion, minecraft got deleted from my computer. When I had the launcher before I didn't download it from the actual minecraft site, I put it in a file in evernote from my iPod (because my computer has parental controls on it and I can't get to minecrafts site.) My mom realized it wasn't actually downloaded to my computer so I tried downloading it (from minecraft.net) but every time a pop up came up saying it was a damaged file and couldn't be opened so I needed to move it to the trash. When I looked at the file in downloads it said the file was 149 KB when online it said it was supposed to be 270 KB. I turned off pretty much all of the parental controls and firewalls and it still isn't working so I just played through that evernote file like before. When I logged in my world's weren't there. I'm so frustrated and I'm not sure why it isn't working. Any ideas? If you need any more information let me know

A. I'm not sure if the problem is that yuor launcher is not loading orthat your worlds are not there, but forthe launcher, make your you downloaded the mac/linux version, and for thewrlds, its normal that your world worlds are not there if you changed pc. you had tosave your worlds on a USB key and then put themback in /.minecraft. Hope i helped!!:D

what are some AWESOME apps for android?
Q. I download the most convincing;)

A. The list

1. Google Voice

Google Voice is a service that is so useful I consider it one of the top benefits of Android itself, especially since Apple rejected the Google Voice app for the iPhone. It gives you a phone number that can ring to multiple places or devices and it allows you to access all of your voicemail and text messages over the Web. The Android app integrates even deeper. It can make outgoing calls look like theyâre coming from your Google Voice number so that you can keep your real mobile number private.

2. Advanced Task Killer

One of the realities of having a multitasking mobile OS in Android is that you have to manage your apps so that they donât hurt performance or battery life. Advanced Task Killer (or ATK) is my favorite. It even comes with a widget that you can tap once to kill all open apps.

3. Dropbox

Dropbox is a great cloud service that automatically syncs a folder of files between multiple computers (Windows, Mac, or Linux). This app extends Dropbox to Android and interacts with other apps (such as Documents To Go) to open the files.

4. Evernote

Once you get used to typing on a virtual keyboard (and it honestly took me over a year to do it), then these devices are great for note-taking, and Evernote is a great note-taking app. It is similar to Dropbox in that it saves data locally but syncs it across all your machines and devices.

5. DroidAnalytics

For some reason Google doesnât have an official app (for either Android or iPhone) for Google Analytics. The best one Iâve found on Android is DroidAnalytics. Another good one is mAnalytics.

6. Documents To Go

The free version of Documents To Go offers a great little reader for Word and Excel files. You can upgrade to the full version (for $15) if you want to edit files and add PowerPoint files to the mix. If you do want editing capability, Iâd also recommend taking a look at QuickOffice.

7. Amazon Kindle

I never warmed up to the Amazon Kindle e-reader, but Iâm a big fan of the Kindle mobile app. Since it was released Iâve read a lot more books simply because my smartphone is always with me and I can pull it and read a few pages anytime Iâve got a couple minutes free.

8. Places Directory

This is an awesome app for finding shops and services near your current location. From restaurants to movie theaters to medical facilities to taxis, this app is very accurate and takes advantage of the business information from Google Local. This app is better than the info you get from a GPS unit (or app) and better than any of the similar apps available on the iPhone.

9. Tripit

I dig Tripit. It is by far the best app Iâve found for keeping track of all my travel itineraries. It runs on some great backend systems. You simply forward your confirmation emails for your flights, hotels, rental cars, and more to Tripit and it automatically organizes them into trips with all your details and confirmation numbers.

10. Seesmic

Twitter is an amazing instant-intelligence engine and it was made for mobile browsing. Although thereâs an official Twitter app for Android now, Seesmic is still the best Android Twitter client.

11. FCC Speedtest

Iâm obsessed with running speed tests to check my bandwidth in various places, both to see 3G fluctuations and to check the quality of Wi-Fi. There are a number of really good speedtest apps, but my new favorite is the FCC Test app.

12. Astro File Manager

Another one of the great things about Android (if youâre a geek or a tinkerer) is that you have lower-level access to the system itself. Astro is an app that lets you navigate the Android file system.

13. Got To Do

There are plenty of to-do apps to choose from on Android but I prefer Got To Do because of the solid interface and the fact that it can sync with the online service Toodledo.

14. Gist

Many of us have contact lists scattered across various computers, devices, and online services. Gist is a Web service that can bring them together and even pull in stuff from the Web to help you stay up to date with your most important contacts. Thereâs an Android app as well as an iPhone app.

15. TED Mobile

TED is a fascinating event that features a meeting of the minds of some of societyâs most influential thinkers. Youâll definitely disagree with some of them, because thereâs a large diversity of opinions, but many talks are worth listening to. What I love is that theyâve taken the videos from their conference and made them freely available on the Web. This app provides a great way to access the videos. I hope more conferences follow TEDâs lead on this.

How do install mpeg decoders and flash for linux fedora 10?
Q. I am completely new to linux fedora and linux for that matter. I am running fedora from a live usb until i get these issues fixed. I apparently need to install mpeg decoders, xvid decoders, avi decoders and a flash player. Being a complete noob to linux I don't know how to go about this.

A. It looks like the decoders are not patent free and fedora will not include them. Other linux distros do allow a user to install them if they wish at their own risk.
The second link has instructions for flash.
You should search the fedora foum for more info on the codecs.
Good luck

Does every game on linux work on every distro?

Q. I wanted to try out Linux. I wanted to either get Fedora or Ubuntu (Mostly Fedora). So I'm a PC gamer, and I wanted to try out the Steam on Linux so my question is:
Most of the games on Steam say that they require one of the three distros Ubuntu, Fedora, and Mint.
Some other games say they only require one (usually Ubuntu) which sort of makes me think that means thats the only one that it will work on. So if it list just one of the distro does that really mean it can't at all run on any other Distro?
By the way the Linux game I'm looking at is Serious Sam 3, which is one of those games that say they only require ubuntu.

A. It depends on how it's packaged.

A game developer that just releases a .deb with Ubuntu in mind just hung Fedora and SUSE users out to dry because they use .rpm packages. Of course if the source code is available one could always compile the game manually, but that doesn't mean that every "Linux program" works on every distribution by default, as they obviously don't.

Steam for Linux is still in Beta, so things are still up in air, as you've noticed with the varying system requirements; it often seems that Valve is really targetting the Ubuntu and Ubuntu-derivative segment because it thinks that's where the biggest user-base is, but I'm sure Fedora and the other rpm distros won't be completely ignored.

How do I run Steam games on Linux?
Q. I got Steam to work on Linux using Wine. All my games worked just fine for a while, but all of the sudden none of them will run (except Portal for some reason). When i try to open them it says, "Preparing to launch," then does nothing. Does anyone know what the problem is, or how to fix it?

A. You could use a program like WINE (Windows Emulator) to get it going. Or you can try a virtual machine but sometimes that wont load drivers and you still wont be able to play. The best option will be a dual boot of windows and linux. The reason being, that for the sake of stability, for the drivers to work, and for you to get a good performance it is just easier to play on Windows (since all PC games are generally designed for Windows environments).

How can i play COD MW2 on Linux Ubuntu?
Q. So i bought MW2 and installed steam on linux and then installed the game... after it finished, i launch the game and it opens but with a dark screen and the words seem to be corrupted , like they do not appear and i cant do anything with it... how can i play MW2 on my computer, although i have Wine and the game opens through it already,,, what should i do?

Thanks in Advance,
Adam.
i did install wine from before... and i dont know how to open the game in window mode , can you please tell me how?

A. Try using PlayOnLinux. It will configure Wine automatically for COD MW2.

How to save file to desktop using Linux commands.?

Q. I am a beginner to Linux commands. I use SSH to connect to a Linux server. What command can I use to save a text file on the server to my desktop? Example?

A. From your desktop, fire up a terminal, or use Cygwin if you're under Windows (make sure you have installed the openssh packages) :

scp <your_user_name>@<server_name>:<path to remote file> <path to local dir/file>

Enter your password, and you're done :)

How hard is it to run a secure Linux server, with Apache, PHP, MySQL, and mail services?
Q. I will be getting my own dedicated server soon and while I have a functional knowledge of the concepts of Linux, I don't know everything. Will my server be reasonably secure if I am sure to keep everything updated and patched (assume there are no PHP scripts vulnerable to SQL injection etc.)

A. Make sure you have strong passwords for everything. This includes your database. Use SSH to connect, scp or some other secure program to transfer files (not vanilla FTP, since it transmits passwords in the clear).
If your database doesn't need to talk to other hosts, configure it so it only listens on the loopback interface.
Be careful when configuring your mail server, so it isn't an open relay.
Get a cert for the web server, so you can use SSL to protect information that gets sent over the net.

The biggest potential source of vulnerabilities will be from whatever web apps you install. Subscribe to the announcement/security mailing list(s) for those apps (and for the Linux distro you use), so you don't get blindsided. Before you install something, you might want to check out a security site (like Secunia) and search to see what advisories have been issued for that software w/in the recent past. This will give you an idea about just how worried you should be about potential issues down the road (and what current issues there are that haven't been fixed, yet).

If you're rolling your own web apps, there are a whole bunch of things to watch out for, especially if you're doing things with user data (file uploads, SQL searches, form processing, etc).

How do I upload a folder recursively via SSH through a linux terminal?
Q. The problem is quite simple actually. I have a folder in my desktop which I want to be able to upload to my server via SSH. I want to be able to do that using only the linux terminal. Thanks
I don't know about import/export functions. I just want to upload via SSH. I know it's possible, I just don't know how.

A. See the SCP command (syntax in source link). It copies files over ssh. As you can see, it has an option to put an entire folder over at once.

Alternatively, there's SFTP (secure-ftp) which tunnels a ftp connection through ssh (valid only if the target server also has ftp service in addition to ssh).
