You'll need to provide a bit more information. But in general, if it's
Unslung you're probably out of luck.

SlugOS should support large files like any other Linux system.

2GB is the maximum number you can fit into a signed 32-bit integer. A
lot of archaic filesystems --- including SMB (although this may have
been fixed in recent versions) --- store file sizes in said 32-bit
signed integers, so you can't have files bigger than that.

All modern file systems now allow proper 64-bit file sizes, so this
isn't a problem any more, but if you're stuck with SMB when transferring
files to the device, you're not going to be able to get large files onto
the filesystem.

You could use (a modern version of) NFS, or WebDAV, but that's probably
going to involve installing more software onto the device.

[LINUX_Newbies] Re:Linux Capable Printers

 

Dear Majorridge67:
Go grab an HP OfficeJet 6310 4-in-1. I purchased mine about a
month ago at Office Max for $55.00. (Yes, it was a big sale.) I
plugged it into my router via a CAT-5e cable. I connected my Ubuntu
laptop via wireless to the same router. I told the laptop to hunt for
network printers. It asked if I wanted to install the 6300. I said
'yes'. It then downloaded the drivers and did the setup. Now I am able
to print from the comfort of my living room chair. (I am in this chair
now and my lap is crowded. It contains a Ubuntu laptop and a Siamese
cat who is trying to sleep.)

The HP6300 is a FAX, copier, scanner, and printer. The printer portion
is color inkjet so it is also color FAX and copier. And I paid $55.00.
(I also purchased the three year warranty for another $15.00.) Because
I purchased it locally, shipping costs were zero. Call around.
It came with starter ink packages. I am yet to run out of ink but
my ancient B/W HP LaserJet 4L does the bulk work.

Re: [LINUX_Newbies] Enlightenment with *buntu

 

This is funny, I considered installing Enlightenment a few days ago to
see how todays version runs but I have not done it yet.

The last time I used it was about 8 years ago on a really slow machine.
The machine was used for bookkeeping in my parents deli. KDE +
spreadsheet program was too much for the little system but it worked
fine with Enlightenment.

I just checked and Enlightenment is in the ARCH Linux repo so I will
give it a spin around the block later :)

[LINUX_Newbies] Enlightenment with *buntu

 

I have been running Kubuntu (jaunty, presently) for some time--although I also have Gnome installed for some variation from time to time.

Recently, I have been getting some crashes, largely because of the *many* browser tabs I usually have open at any given time, along with a few other programs running.

Just for kicks, I decided to check out the Englightenment window manager--and WOW, I *like* it!

It turns out that E16 uses fewer resources than KDM or GDM, and seems thus more stable on heavily loaded machines like mine. It is also much faster and more memory efficient even than XFCE--which, these days, seems to have somewhat lost its way a bit from the days when it was a truly lightweight alternative to KDE or Gnome...but I digress.

The current stable version of Enlightenment, E16, is available from the Ubuntu repositories. When you install it, you have various options at boot time. If you have both KDE and Gnome installed, for example, you have preconfigured choices to run KDE with Englightenment as the window manager; Gnome with Englightenment, or Englightenment by itself as a super-fast and lean (but eye candy filled, if you wish) window manager. Of course, you also have the straight KDE or Gnome options as well.

It works a little differently, but as you become used to it you will be amazed at the speed and utility it brings to the table. Instead of hte KDE menu button or the Gnome menu buttons, for example, with Englightenment you click on the desktop background anywhere--left button for the application menus, right button for configuration settings of all sorts. If you have booted into Englightenment +KDE, as I am doing presently, you have both.

Also, the desktop is very interesting. Let us say you have both a browser and, perhaps, a video player running. You can switch between them simply by moving your mouse to the side of your screen. Very slick not having to minimize/maximize all the time, but a little disconcerting when you are in the window that slides to the next on the right side--if you aren't too accurate with the scroll control on the right of the window, you suddenly find yourself in the other desktop.

I have not yet reset my number of desktops above two--I will do that later today just to see if the windows continue to scroll through the higher number wit the same method.

Also, opening and closing application windows is very fast.

There are entire distros which use Englightenment as the primary window system. However, I am very pleased with having such a large user community and the enormous repositories with pre-configured apps in the Ubuntu family. I also believe that having a primary distribution used by increasingly large numbers of people is an advantage in seeking to further the Linux penetration in the marketplace. Thus, I am happy to see such flexibility and am always discovering new things to make my computing more efficient and fun.

So--if you have never used Englightenment, give it a shot. You may be pleasantly surprised.

David

Thank you! I'll go through these and see what I find.

Re: [nslu2-linux] Slug hangs when trying to create directory on a 1Tb ext3 drive

 

gullaugu wrote:
> I am running slugosBE 5.3 and have nfs and samba set up. Recently, trying to create a directory through nfs freezes the slug and only plugging the cord works for getting it back. ssh won't work and I don't have a serial cable. Trying to create a directory directly from the slug doesn't freeze it, but the ssh connection is reset and I can't log in again. But the power button actually does its thing. Connecting that same drive to my laptop (after fsck) and I can create the directory.

You're almost certainly running into limitations in terms of physical
memory. There are no limitations to the number of directories. Rather,
there are limitations in that in order to perform certain operations,
the filesystem code needs to have certain data structures in-memory.
And when memory is in such short supply, the result is often bad,
triggering the kernel Out-of-Memory Killer process (which is most likely
the cause of the symptoms you describe).

You can try to enable swap -- but since your issue is happening on the
drive's filesystem, you probably want a swap partition, not a swap file.

You can try using an ext2 instead of ext3 filesystem; some small amount
of memory might be saved by not having the journal. You might try
another filesystem format altogether; perhaps jfs handles large
partitions in a less memory-intensive fashion. But the best solution is
probably to re-partition the drive to smaller partitions; a pair of
500MB partitions might work, but I would use nothing larger than 250GB
(which seems to be the largest size that can actually be fsck'd on the
NSLU2 without running out of memory).

Aaah ... so "ipkg-opt search" only search installed packages? Is there
a similar command to search in available packages?
I got it working now, thanks.

Re: [Java] Path - Workspace

 

Have you tried hardcoding the path in your new File () statement?
File file = new File ("C:\\myWorkspace\\MyProject\\new.txt");

Or, make it a little more portable:
String dir = ... // Possibly get the value from a .properties file?
File file = new File (dir + "\\new.txt");
