OK, script idea, guys. I wanna know when my dad's computer is up. Of the top of my head, i know i can do something like while [ 1 ]; do ping -c 1 192.168.0.xx &> /dev/null ; test ! $(echo $?) || wall " Win 7 is up "; sleep 360; done

But is there any better ideas ?

install qt of course

Nathan Osman

And the installer's giving you a segmentation fault?

Serg

yessir

Nathan Osman

Why don't you want to install Qt from the archives? It's much easier.

sudo apt-get install qtbase5-dev

...and you can install Qt Creator with:

sudo apt-get install qtcreator

danidee

Good day people....first time in the room

Nathan Osman

@danidee Welcome!

Terrance

@danidee Hello!

danidee

Technically i'm still a noob when compared with other seasoned Ubuntu users, i've been using ubuntu for over a year now and i chose it because it's the most stable distro i've used till date....i used to like Kubuntu, but some applications where crashing too frequently for no reason so i ditched it

Why do you guys use ubuntu over distros?

Terrance

More compatible for me, and better application support across repositories, etc.

Nathan Osman

4:06 AM

I use Ubuntu for its ubiquity and widespread use within the developer community.

danidee

Everyone around me uses windows....i've tried spreading the ubuntu philosophy but most people are too lazy to learn something new and they don't even like the idea of using the terminal at all

Terrance

Mac users do the same.

danidee

i have a friend who always tells me that Macs are the best and so on.....but seriously i really don't see anything special about them that PC's or Linux boxes can't do so i just call them overrated and overpriced boxes and it really pisses him off

Nathan Osman

Give them a set of about 200 consecutively numbered images (0001.jpg, 0002.jpg, etc.) and then challenge them to convert each of them to PNG files and switch the order (0001.jpg becomes 0200.png, etc.).

danidee

the only thing that seemed special about osx was the lack of viruses, but it didn't seem special again when i discovered ubuntu

Nathan Osman

4:16 AM

That would be trivial to do with a command in the terminal.

danidee

i thought mac also uses bash....a seasoned mac user should be able to do that also

Nathan Osman

Hmm... good point.

Except they would need to install an image conversion program like ImageMagick, I assume.

I have a Mac, but I don't use it that much. It's mostly for testing purposes.

danidee

but i'm very confident that he won't be able to do that though

Nathan Osman

:)

Terrance

Looks like i missed some conversation here when I walked away.

Scripting on the Mac is much different then on a PC running Linux. Library calls are different, and hardware calls are different. To make a script to work on both, it basically has to be two scripts in one.

Nathan Osman

4:21 AM

Or you could use Python :)

I haven't had to modify any of my Python scripts when running them on my Mac.

Terrance

Say, you need a script that can capture TCP packets from the active network connection.

danidee

yeah with the os module i think

Nathan Osman

@Terrance That's a bit... low-level.

Terrance

I can do that in bash without a problem :)

getting standard eth0 output was easy.

Nathan Osman

Yeah, by calling external commands :P

Terrance

4:24 AM

I tried it on the mac, and I would have to rewrite the script to work.

It's hardware calls are different

danidee

i was just wondering ubuntu uses samba/smbd to share files between two computers does windows use the same?

Nathan Osman

Yes and no. Windows does indeed use SMB. Actually, SMB is just one of many protocols for transferring files on Linux.

Incidentally, I'm the author of a program that simplifies transferring files among devices on a local network.

Terrance

=)

I would have to find some of the scripts I have written for work here. Some of the guys on my team like to use Macs, but they still log into Ubuntu or RHEL servers for the majority of the work commands they use.

But my preferred is two separate systems, one Ubuntu and the other Windows. Ubuntu for all the server work and Windows for all the admin work. Plus, I get more real estate on monitors and using Synergy between them. :)

Nathan Osman

At one point, I wondered about installing Xen on my desktop and running both at the same time :P

Terrance

Not familiar with Xen.

danidee

4:32 AM

i'm also working on a file sharing program just like yours to share files via wifi but mine would strictly run on windows....just trying to do some research

Nathan Osman

It's a bare-metal hypervisor.

Terrance

Ah, yes, hypervisors I am familiar with. They are used on a lot of our servers for the VMs, depending on what the server is used for.

I will take a look at Xen. :)

danidee

@Nathan i just installed nitroshare....nice work i also want to use qt but with python

Nathan Osman

@danidee Thanks.

Yeah, PyQt is a great library too.

danidee

i use PySide but the differences with PyQt are not much

do you plan on adding support for internet connection sharing in the future?

Nathan Osman

Cool.

@danidee You mean sharing files outside of a local network?

danidee

no...like me connecting to a friends computer and using his internet

Terrance

Internet Connection Sharing?

Nathan Osman

No, I don't have any plans for that at this point.

@NathanOsman how does smb on windows and nix systems differ

A.B.

4:51 AM

Interesting question

Nathan Osman

The most common SMB implementation on Linux is Samba and its goal is to mimic how Windows uses the protocol as closely as possible.

danidee

and i think windows would also want to keep that closed

Terrance

Why not? They have kept the PrintSpooler closed, and it sucks! ;)

Nathan Osman

They're also pretty tight-lipped about NTFS. Lots of reverse-engineering was required to get that working well on Linux.

danidee

oh oh Windows....Did any of you get fooled on 1st April by that Miux article too
