How can I change the amount and size of Linux ramdisks (/dev/ram0 - /dev/ram15)?
You should use tmpfs for that instead.
mount -t tmpfs -o size=10g none /mnt/point

Actual file size on mac os x
To see the total of just one specific folder use:
du -s /path_to/specific_folder/
To see to total of each folder in one specific folder use an
asterisk:
du -s /path_to/specific_folder/*
If you don't own all of the files in those directories use sudo
to be sure everything is counted.
Edit: Ah, I understand what you are asking now. You want:
du -sk /path_to/specific_folder/

Why are the sizes of 2 directories different if the data within the directories is identical? They are identical ext4 partitions and disks
The size reported by ls -l for a directory has no
relationship with the cumulated size of files stored in it.
It is just, for most common file systems, the size in bytes that
has been required to store the directory entries. This size grows
by block size (eg: 4096, 8192, ...). How many entries can be
stored in a block is file system dependent and vary also with
entries filenames length.
When directory entries are removed, the directory size is
unaffected to reduce fragmentation.
In your example, the external3 directory has
18 * 4096 blocks allocated while the
external4 has 17 * 4096 blocks.
That just means the former stored once more files (or files with
longer names) even while the directory contents are currently
identical. No big deal.

Why does Windows occupy more disk space, compared to Linux?
It is a very difficult thing to say...
There isn't really one answer fits all, for Ubuntu, it is mainly
because it installs a subset of tools plus every day ones.
Anything you want extra is downloaded when you need it (Such as
frameworks for other programs)...
Windows Vista and 7 on the other hand copy the whole contents of
the DVD to the drive and any Windows components you want to
install at a later date do not require the disk to be put in.
Again, this is a very awkward question... I am not exactly sure
what to say! It can be also said that you can get string from two
different companies with different widths, yet they can both tie
knots...
If you are just curious, I would download Vlite so you
can take out components and just have a play to see how small you
can make Windows.

Delete Directories smaller than x
Try du -sk * | awk 'BEGIN { FS="\t" }; { if($1 < 1000)
print $2 }' | grep '' -Z | xargs -0 -s 1024 rm -rf. Be
careful with rm!

How to change the size of desktop/window fonts in Puppy Linux 4.1?
Not using Puppy, I wonder if this article has the answer :
Puppy 5 - Font size too small
menu / desktop / desktop settings / set global font size,
change font size, restart X

How to increase VirtualBox virtual drive actual size?
If you want to add space to the guest, there's 2 places it needs
done: First in the virtualization host itself (Virtualbox, in
your case), then again inside the guest.
If you originally created the virtual drive as 4 GB, then later
resized it to 8 GB, you'll need to do some work in the guest OS
to have it makes use of the extra space. Right now it's as if you
took a 4 GB partition and put it onto an 8 GB drive -- the
partitions haven't changed, so the rest of the space is
unallocated as far as the guest is concerned. You can either add
a 2nd partition in the guest or use some utility to resize the
partitions in the guest.

file size returned from ls - Linux vs OS X
Likely it's the file system. The command is probably reporting a
value as the size on disk rather than the actual size, and since
each machine may be using a different cluster size, you see
different values. More on the topic
in this question.
You can use tune2fs -l to see how your file system
is currently configured.

Limit/rotation of ~/.xsession-errors?
You should realy try to solve the problems that cause the file to
grow.

How can I find out the size of a swap partition?
The sizes are in kilobytes since swapon -s is
equivalent to cat /proc/swaps.
If you want to see the combined swap space use free.
It can sum and convert to, for example, megabytes: free
-m.

The
GNU size utility lists the section
sizes---and the total
size---for each of the object or archive
files objfile in its argument list. By default, one
line of output is generated for each object file or each
module in an archive.
objfile...
are the object files to be examined. If none are specified,
the file "a.out" will be used.
options
The command
line options have the following meanings:
--format=compatibility
Using one of these options, you
can choose whether the output from GNU
size resembles output from System V size
(using -A, or
--format=sysv), or Berkeley size
(using -B, or
--format=berkeley). The default is the
one-line format similar to Berkeley’s.
Here is an
example of the Berkeley (default) format of output from
size:
$ size --format=Berkeley ranlib size
text data bss dec hex filename
294880 81920 11592 388392 5ed28 ranlib
294880 81920 11888 388688 5ee50 size
This is the
same data, but displayed closer to System V conventions:
$ size --format=SysV ranlib size
ranlib :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11592 385024
Total 388392
size :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11888 385024
Total 388688
--help
Show a summary of acceptable
arguments and options.
--radix=number
Using one of these options, you
can control whether the size of each section is given in
decimal (-d, or --radix=10);
octal (-o, or --radix=8); or
hexadecimal (-x, or
--radix=16). In
--radix=number, only the three
values (8, 10, 16) are supported. The total size is always
given in two radices; decimal and hexadecimal for
-d or -x output, or octal and
hexadecimal if you’re using -o.
--common
Print total size of common
symbols in each file. When using Berkeley format these are
included in the bss size.
--totals
Show totals of all objects
listed (Berkeley format listing mode only).
--target=bfdname
Specify that the object-code
format for objfile is bfdname. This option may
not be necessary; size can automatically recognize
many formats.
--version
Display the version number of
size.
@file
Read command-line options from
file. The options read are inserted in place of the
original @file option. If file does not exist,
or cannot be read, then the option will be treated
literally, and not removed.
Options in
file are separated by whitespace. A whitespace
character may be included in an option by surrounding the
entire option in either single or double quotes. Any
character (including a backslash) may be included by
prefixing the character to be included with a backslash. The
file may itself contain additional @file
options; any such options will be processed recursively.
