Quick question--I am going to run the latest version of knoppix straight from the CD/DVD drive. Will I be able to run/install programs and use the bluetooth hardware on my laptop?

Would someone be willing to give me a crash course in compiling and running a c program in KDE? I've got the latest release running, a program.c and makefile files(not written by me), but I can't seem to figure out how to get them up and running. It's been a long time time programming 101 and even then I only got my feet wet in java. I think I'm using the cc99 command for compiling in KDE, although I must be doing something wrong since the program kicks out a bunch of errors when compiling. If there's an easier way to do this than the KDE compiler someone please let me know. Could someone just write up a quick how-to, if that's even possible?

Also, ubuntu doesn't ship with development tools. Make sure you have them. The quickest way is via the "build-essential" meta-package: apt-get install build-essential.

[edit] durrr, you're running c99, you have dev tools. What happens when you type 'make' ?

I get a series of errors with my c program to the effect of "warning: incompatible implicit declaration of built-in function 'strlen'"

The bolded part looks very odd to me. All errors seem to stem from the fact that the included files mentioned (and also the standard library files) are not found, which may or may not be caused by the "-Iinclude" bit. Can you post the makefile, too? Where did you get this program & makefile?

makefile -

CC = gcc
CFLAGS = -W -g3
LD = ld
LDFLAGS = -lbluetooth
SRC = src
INC = -Iinclude

all: program

program:
$(CC) $(INC) $(CFLAGS) $(LDFLAGS) $(SRC)/program.c -o program

Using Wine, Photoshop doesn't work flawlessly. (GIMP is alternative for most of its functions). Some winamp functions don't work (eg playlist) - use amaroK as its better.

If you're willing to pay, Crossover office will handle MS Office, iTunes etc.

Perhaps if you told us what you use we can tell you if there is an alternative?

Not really trying to do anything, was just curious which other big name software apps don't support Linux, as you mentioned iTunes and Photoshop being iffy. Any others of note?

I'm a linux noob, but I have a system running ubuntu. What's the easiest way to run Windows without doing a dual boot? I was thinking VMWare or WINE. Which of these, or any others, would be easiest to setup and use?

Also, WINE Is Not an Emulator.

I guess some games and emulators that won't run in Linux (NullDC is one) as well as some other video encoders and junk that I've just gotten used to in Windows. I'd just like to have both OSes at my disposal without having to reboot.

VMware doesn't support 3d acceleration in Windows, so you will not be able to play recent games. You should try Wine for this; many games work well with only a mild speed penalty. I would see how much you can get out of Wine before resorting to a full-blown VM. It is easier to integrate individual applications into your desktop with Wine.

I think I'm going to try out VMWARE just for my own enrichment. Which specific product should I get?

drat, already hit a snag. I'm running Ubuntu, but for some reason I can't connect to any of my office's wireless networks. I can see the networks fine in the manager with good signal strength, but when I connect, it asks me for the passphrase, which I put in, then it just has the warning symbol in the network icon. I connect to the same network easily in my Vista dual boot, but no such luck in Ubuntu. Is there a way to check the driver? Not sure why I can't connect.

Does anyone know if there is a way to point a virtual machine in VMWare workstation to run off of an existing partition? I've already gotten one VM running with a fresh install of vista, but I was wondering if there was a way to access the existing Vista partition and just use that.

Just saw a link to this on digg: http://linuxmce.com/

Looks pretty sweet, in my opinion. I was wondering if this would work on the Apple TV. Looks like you need a Kubuntu installation, which I guess would have to be done over SSH. I'm not very advanced with Linux, but I did mod my Apple TV. Anyone think it's worth a try?

Why are we seeing so many Linux-based mobile devices? I dunno about you guys but I've noticed that everything from Archos PMPs to Open-Moko seem to be running Linux, these days. Maybe it's just a product of all the GoogleOS chatter, but I was curious if anyone knew of any sales figures or patent filings related to this trend?

Are there any simple precautions I can take to prevent my AWS instance from being taken over by that mirai flaw? I already have all my ports closed by default apart from 22, 80 and 443 (only my ip). It looks like my image provider bitnami isn't supporting my version anymore so I don't think there's any patches available. This is bitnami Moodle 2.7 if that makes a difference.

Stupid question. I'm trying to log into my AWS ubuntu server with ssh on my Mac's terminal. I have my ppk file which works just fine on Windows with putty. I converted with puttygen for a pem file and generated a public key with puttygen but whenever I try to SSH I get a public key denied error. I have openssh installed. No idea what's going on here. Any ideas?

I tried the regular ubuntu server 16.04 iso but it doesnt seem to have a boot from USB option. I used to use knoppix in the past but id prefer some flavor of ubuntu.

Can someone spot check my crontab tasks? What it should be doing is running an iostat for CPU usage, running a stress command, then uploading the cpu file to S3. Appears to be working correctly just want to be sure.
