Peter is a Windows programmer. Didn't you know?

Once upon a time there was a DOS user who saw Unix, and saw that it was
good. After typing cp on his DOS machine at home, he downloaded GNU's
unix tools ported to DOS and installed them. He rm'd, cp'd, and mv'd
happily for many days, and upon finding elvis, he vi'd and was happy. After
a long day at work (on a Unix box) he came home, started editing a file,
and couldn't figure out why he couldn't suspend vi (w/ ctrl-z) to do
a compile.

Guffaw.
The man who couldn't understand how it was trivially easy to create a
contiguous swap file on a new Linux partition? The man who refused to
believe that a swap file was as fast as a partition in 2.6 when set up
correctly (despite him being given links to Andrew Morton's comments on
the subject)? The man who claimed that you cant see anti-aliasing in
screenshots?

Oh, Hadron, you still failed to explain *how* to do it. Dispite dozens of
questions how to achieve it

Nope, Hadron, the man who doubts that a non-contiguous swap-file is as fast
as a contiguous swap-partition. You know, you have not yet provided a
single answer how to achieve a contiguous swap-file. Although you claimed
it could not be allocated non-contiguous. Acoording to you, the "tools
don't allow it to be allocated non-contiguous"
Which is bullshit to the extreme, naturally. You don't have any clue at all
about swap-files/swap-partitions

Some "faulty units".
Oh yes, certainly.
You failed to mention that the URL does not talk about those at all
It talks about a severely borked iPhone. *All* units of it.
And those "some bugs" in it are the same ones found in "Safari for windows",
which were show-stoppers. The phone can be taken over by malicious code to
do whatever the bad guys wants it to do.
Which shows that apple not only has no idea at all about code quality, but
that they relaese pre-alpha code in *cell-phones* to the public. In devices
which should have been very thoroughly tested. And obviously were not.
It could have been just as well a roll-out from MS

It's a very nice product however my sister spent 3 days attempting to get

Not the fault of the iPhone but ATT. The only complaint I have with it is
that the 'keys' are too small and it's going to be a PITA text messaging.
The 'keys' are not physical keys of course, they are on the display.

Apple makes great products that are highly innovative
but they are not inexpensive.
If you have the money though it's an excellent alternative to Microsoft.
> Peter is a Windows programmer. Didn't you know?
Why? Where I live plenty of Linux programming and systems type jobs exist.
There is much need for Linux programmers for embedded devices.
However on the consumer side of things Linux is a virtual unknown. At my school
we have a Linux club which is crazy but the average student has either an iBook
or a Microsoft Windows based system. I use Linux because I like it and because I
have an older laptop and Windows XP crawls on it while Ubuntu and PCLinuxos
are both quite fast.
I don't see Linux becoming a major player for home users soon though because
Microsoft is too entrenched in the market. Even with the Vista fiasco (Vista was
banned from my school this semester and a decision has not been made yet as to
whether or not it will be allowed in the fall), Linux is still unknown to all
but technology fluent people.
Hopefully in time this will change but I don't see it happening for a long time.

Nope, not trapdoor.
The iPhone Safari exhibits some of the same security botches like its
windows cousin. Apparently they share at least partly the same codebase.
Those guys have successfully cracked the iPhone Safari. It would be possible
then to dial expaensive phone-numbers without the user having any clue
about it
They also cracked the default user and root passwords. Because apple decided
it was safe enough to encrypt them with DES.
Nope, apple goofed here big time, and until they reflash all the units
already sold with safer software, this could turn out "real bad (tm)" fast.
And they provided another example of apple delivering crappy stuff.
Although, according to Hadron Quark, this can't happen

Interesting stuff. I didn't know that.

Yes, that's just what I though. It could turn out to be rather bad because one
hole might be related to another. Just think of Sony battery recalls. Also
think about taking units off the shelf and postposing sales until examination
of the code is carries out. Safari on Windows was a mess, security-wise. Not
the case with Firefox even though the code is out there for all to poke with a
big stick...

Good. Then you will be able to show us your complete, self written BIOS?
Here, let me help you:
http://www.programmersheaven.com/download/15830/download.aspx
I have no idea how this one ended up there, as it was origally distributed
by the german magazine "c't" (under the provisions that they provide it
cheap). But I don't mind, as it still can serve as example how several
basic BIOS functions work.
This is the IBM compatible BIOS for original PCs/XTs fitted with the NEC V20
processor. It is the older version, I later released one with code which
was able to emulate the CGA graphics on a Hercules-card (monochrome,
naturally). Was a boon for the guys who wanted to play some CGA-only games
but had only the better display quality Hercules monochrome card

Wait a second...he said "on a new Linux partition". It's trivial to
make a contiguous file on a new partition. Just "dd if=/dev/zero
of=my_swap_file bs=1024 count=SOME_BIG_NUMBER" and it will almost always
be contiguous. You can check it with filefrag, and try again if it
isn't.
On a partition that has been used heavily for a significant time, I
don't know of any good way to make a large contiguous file. I could
kludge it, but it would get ugly.
However, you don't need a contiguous swap file. A small amount of
fragmentation won't affect performance in any way that you'd be able to
notice. Think about how the kernel uses the swap file and this will be
apparent. As long as the region of the file used for any given swap
operation is contiguous, fragmentation does not lead to a performance
penalty.

Right. *Almost* always. *Not* always.
But it is Hadron Quarks claim that the tools do not even let you create a
non-contiguous swapfile. No mentioning of "new partition" and the like
Additionally, what good does it do when you can create a swap file only on a
newly created partition? You are better off doing swap partitions then.

But that was not his claim. Not even close

Right. But usually one creates a (maybe additional) swap file because some
task needs more memory space. That can be anytime in the use of a computer,
not just at the start of it

I know that you don't.

I know that also. But a swap file will *not* have the *same* performance as
a swap partition. It will be (slightly) slower because of fragmentation.
Additionally, a swap partition will be usually on the outer tracks of a
disk, where the disk is fastest. A swap file will *always* be located more
to the inner tracks. Adding additional (very small) performance penalties

But that is all irrelevant RE Hadron Quarks claims. He claims bullshit, he
gets educated on it and then retroactivly tries to change the tone of what
he said. He is a lying, extremely dishonest twit

I did a closer look at that code just now. It is *partially* my code, and
other code seems to be ripped directly from the original IBM-BIOS.
I got curious because the comments were all lowercase, whereas I wrote lots
of comments in uppercase or mixed case
So no, that BIOS is not mine, it cointains /some/ of the code I wrote.
My V20-BIOS was also released mch earlier, and as people got source code
with it (it was *NOT* GPLed) that guy who put it there has taken some of my
code and added others too.
Why, I don't know. But my code was way more effective than that one
One example: The CGA could output Text in graphics mode, but that was
relativly slow.
My BIOS was faster outputting text in that mode than the IBM-BIOS was
outputtting text in Text-mode!
