I wouldn't call InterViews 3.1 glyphs "hacks". They give you a choice of
|
|
OpenLook, Motif, or "SGIMotif" appearance with a runtime flag. It's not as

Of course, there's nothing the kernel can do to help your latency

|

|

I don't think you're thinking far enough ahead. The purpose of
|
|
synchronous metadata updates is not to save the file you're writing
|
|
at the time of the crash (or whatever), but rather to ensure that
|
|
the file system itself doesn't creepingly get into an inconsistent
|
|
state behind your back.
|
|
|
|
I'd rather have garbage in a file than have a file whose blocks
|
|
are also in the free list and will soon be allocated to another
|
|
file as well. Of course, fsck is supposed to fix these situations.
|
|
But if you're using a filesystem wherein the actual disk updates
|
|
are trailing way behind file system activity, and are not constrained
|
|
to be written in the order they were made, then a crash at a disk-intensive
|
|
time could leave fsck extremely confused.
|
|
|
|
This is why BSD ffs does its updates in what somebody called the "wrong"
|
|
order, but which strikes me as exactly the _right_ order.

First off, I failed to grasp your point. There are reasons why 2.6.0

The nice "ksh -r" which makes it restricted. I really need that now and have

|
|
|

Well, there has certainly been a lot of work done to secure
|
|
WAN links at varying levels of security, but this work can be
|
|
into two categories: authentication/identification encryption.
|
|
Work was done in the first case primarily to protect remote office
|
|
routers from being swapped with network sniffers or other such things
|
|
that could emulate the router while ripping off their data. The two
|
|
main methods of authentication/identification are PAP and CHAP, the
|
|
latter being the best method.
|
|
|
|
In the area of encryption, I dont believe that there is any
|
|
standard for doing this on PPP links, but many companies (mine
|
|
included) have employed proprietary scrambling mechanisms so that data
|
|
going accross WAN links is kept secure even if it suddenly becomes
|
|
non-private as a result of someone attaching a sniffer to the line.
|
|
|
|
PPP PAP and CHAP are freely available, and usually come with
|
|
most commercial and free implementations of PPP. However, PPP
|
|
scrambling is different issue since it is almost exclusively employed
|
|
in a proprietary fasion. As far as I know, PPP scrambling has currently
|
|
been implemented only between routers, but I may be wrong. If your
|
|
needs require secure WAN links, perhaps purchasing a low-cost remote
|
|
office router which provides dial-on demand connections for
|
|
non-permanent connections to The Internet. However, that solution is
|
|
getting a bit pricy, and is probably out of the relm of most home
|
|
Internet connections.

For stock VGA/EGA, yes this is correct... 8 bits per character for text
|
|
modes and one bit padding which, for a (hardwired I believe) range of
|
|
linedrawing characters.
|
|
|
|
However, there are very few users of "stock" VGA/EGA anymore. I would
|
|
dare guess that the majority of linux users have some sort of SVGA card
|
|
and many SVGA chipsets support extended text mode functions most of
|
|
which I have never seen tapped. Some of the functions that stick out in
|
|
my mind are variable sized fonts, multiple fonts, and anti-aliased
|
|
fonts.
|
|
|
|
The problem lies in the fact that the features available for each
|
|
chipset vary in the extremes... I'm not sure what the VESA
|
|
specification covers in terms of this. This probably means that most
|
|
people will need a separate driver depending on which chipset they are
|
|
using in order to get any of these enhanced features and the available
|
|
features will differ between them... (how, for instance, should the
|
|
system or ncurses handle character colors when somebody is using a
|
|
multiple-colored font?)
|
|
|
|
I don't know if anybody is willing to do work on this or not... or if
|
|
enough people are even interested.

Since 1.1.45(?) there is support for high capacity floppies. Look in
|
|
ftp.imag.fr:pub/Linux/ZLIBC for floppy support programs and the newest alpha
|
|
drivers.

|

Reading 256 byte sectors is possible with 1.1.51 . The sector size
|
|
is encoded in bits 3 to 5 of floppy->rate:
|
|
|
|
Meaning of S:
|
|
0 0x00 ===> 512 byte sectors
|
|
1 0x08 ===> 1024 byte sectors
|
|
2 0x10 ===> 2048 byte sectors
|
|
3 0x18 ===> 4096 byte sectors
|
|
4 0x20 ===> 8192 byte sectors
|
|
5 0x28 ===>16384 byte sectors
|
|
6 0x30 ===> 128 byte sectors (doesn't work yet...)
|
|
7 0x38 ===> 256 byte sectors
|
|
|
|
The two last sizes are new in 1.1.51
|
|
|
|
: Looking at the floppy code for 1.1.45, there
|
|
: doesn't seem to be a coherent strategy for handling different sector
|
|
: sizes. In some places it is assumed to be 512 bytes, in others it
|
|
: is replaced with a #define, which may be either 128 or 512 bytes.
|
|
There are several different sizes involved in the floppy driver:
|
|
|
|
* 512 bytes is the default sector size for floppy disks, and also the
|
|
smallest size that the buffer cache code (VFS) can handle (fraction of
|
|
a buffer).
|
|
*1024 bytes is the default size of a buffer for the VFS. (i.e. two
|
|
fractions)
|
|
* 128 bytes is the smallest sector size that the floppy disk controller
|
|
supports. All sector sizes are powers of 2 and multiples of 128.
|
|
size = 128 << sizecode
|
|
|
|
If you upgrade to 1.1.51, don't forget to apply the patch at
|
|
ftp.imag.fr:pub/Linux/ZLIBC/floppy/QDF/fdp1.1.51-0210.diff.gz
|
|
in order to avoid the well known floppy unmount problems.

Hope this helps,
