- SSM
- As is the case with most Mondays, this will have
to be a short one. Things are a little busy here at
work and, of course, I have class tonight so I gotta'
go.
- Super Bowl Commercials
- Just in case you didn't see all of the Super Bowl
commercials, here's a site that has them all (see it
here).
Needless to say, even though I'm saying it, you will
need a fast connection, or a lot of time, to view
them all. Thanks to InfoWorld's Brian Livingston (see
his column
here) for the link.
- The Need for Speed
- Have Ferrari tastes but a Fiat budget? Want to do
200mph (~322kph) but can't afford the insurance, much
less a car that can do that kind of speed? Well,
you'll just have to get small. As in model cars. In
this case, tethered model cars that supposedly can do
that and also lateral accelerations of about 90Gs.
See the site here.
Thanks for fark.com for the
link.
- Texas A&M
-
A group of [insert the group of your choice] in a
class at Texas A&M were given the assignment to
measure the height of a flagpole. So they go out to
the flagpole with ladders and tape measures, and
they're falling off the ladders, dropping the tape
measures the whole thing is just a mess.
An engineer comes along and sees what they're
trying to do, walks over, pulls the flagpole out of
the ground, lays it flat, measures it from end to
end, gives the measurement to one of the [insert
name] and walks away.
After the engineer has gone, one [insert name]
turns to another and laughs. "Isn't that just like
an engineer, we're looking for the height and he
gives us the length."

- Hardware vs. Software
-
Interesting debate between Daynoters Robert Bruce
Thompson (RBT) and Dave Farquhar recently (see RBTs
column
here and Farquhar's here).
You need to understand that both of these guys have
spent the time researching the respective subjects
of their books and are experts in their fields. But
each looks at the problem from their own
perspective. In RBT's case, it's hardware and from
Farquhar's case it's software.
As I understand it, Farquhar feels it is worth
the time to tweak the software of an older PC to
gain performance versus buying new hardware.
Conversely, RBT is advocating that when the system
seems to be slowing down, if a clean install of the
software doesn't fix the problem, you should buy a
new system. As in many cases, the answer lays in
how much you value your time and how much money you
have versus the cost of an upgrade (that old cost
versus benefit analysis).
Now Farquhar says he can have a 400MHz Celeron
be as responsive as a Pentium 4. Maybe. Sort of.
But getting that system to be so, if it were
possible, would require a lot of tinkering under
the hood and only you can decide what your time is
worth. Not to mention the possibility of breaking
something that shouldn't be broken. I should
disclose here that I paid for copies of both of the
authors above. And to be honest, I had problems
with some of the tweaks Farquhar has in his
book.
One quick example is found on page 48,
Optimizing Your Windows Directory where certain
files are moved into c:\windows\command. Farquhar
has a list of files that he says is safe to move.
But in my installation, doing so caused Windows to
become unstable, even after I copied the files
back. I ended up having to re-install the entire
operating system.
I'll be the first to say maybe my installation
was not the standard so that is why things went
tits up when I followed Farquhar's instructions. I
don't know and I really don't have the time to find
out.
And therein lies the rub. Time. It would be nice
to be able to wring every last cycle out of a PC.
But I just don't have the time. It is far faster,
and for most people far easier, just to reformat
their drive (after backing up whatever they need
(data, mail, favorite links, etc. and making sure
they have the install media for all of their
programs) and start over again. Most of the
defaults from a clean install, while perhaps not
optimum for all of the diverse hardware and
software out there, are usually Good Enough for
most people.
So when I feel my PC slowing down, the most time
efficient thing for me to do is reformat and start
over (something I do at least twice a year). This
still begs the question as to when do you upgrade?
As above, there is no simple answer because you
have to decide what is "too slow" and what is "too
expensive". After all, it's your time and your
money. So although someone could come up with a
formula, that formula would still require you to
fill in the variables.
For example, if you are trying to setup an after
school program to teach disadvantaged children how
to use computers, you may very well want to use
every trick in Mr. Farquhar's book so you can
stretch your limited funds by accepting donations
of refurbished 486s. But if it's your own PC and
you are wondering whether to retire that same 486
with 16MB of RAM, perhaps it's better to pays your
money and get a faster PC (and use the 486 as Linux
router/firewall).
On the other hand, having made the decision to
upgrade, most people should not fall into the trap
of buying the fastest CPU available. Doing so is
very rarely the most cost effective way of doing
things. Due to the pricing schemes of hardware
manufacturers, their top-of-the-line usually has a
equally top-of-the-line price. For what it's worth,
unless you really have a need for the fastest CPU
out there, take a look at the second or third
fastest CPUs because the money you'll save is your
own.
Obviously, this is a very complex subject that
may require you to make complex value judgments,
and to understand the context in which you will
make them. But I think it points out the problems
you can run into if you don't think about the
underlying assumptions in any buying decision.
Assumptions you should be aware of and have answers
for.
- Lawyers. Lawyers. Everywhere.
-
Speaking of RBT, he had a comment about there being
too many lawyers and that the solution was to have
an open hunting season on them. While I don't know
if I would go that far, the analogy that he used,
that of the negative effects of over population is
an apt one. Before I go any further, let me
re-emphasize that this is my personal opinion and
does not reflect the opinion of my employer (see disclaimer).
With that said, how might some lawyers act if
there were more of them than the environment they
were in could support? Would you say that some,
perhaps, would behave unethically, or even
illegally? And could you take that a step further
and say as the number of lawyers, in a given
population, goes past the optimum (whatever that
is), the number of violations increases at a rate
faster than the number of lawyers?
The afternoon paper had an article this past
weekend (see it
here) that indicates Hawai'i may have the
highest rate of reported and punished
unethical/illegal behavior of attorneys in the US.
This may or may not have a direct positive
relationship to Hawai'i having, from what I
understand, the highest rate of lawyers as a
percentage of the population in the US (this is off
the top of my head so it could be wrong. I've tried
finding a source that lists the percentage by state
but have not been able to find anything yet).
In either case, it would be an interesting
debate question: Be it resolved that the number of
attorneys in Hawai'i has reached a level at which
the legal system is now the problem, not the
solution.
Aloha!

- Bullsh*t
-
I'm no Olympic figure skating judge but I have eyes
and even with my glasses I can tell if someone
makes a mistake and when someone doesn't. So I
guess I have to agree with Canadian figure skater
Jamie Sale's comment about the judging.
Having said that, perhaps it is time to admit
that any event that uses a system of judges to
decide a contest will be ripe for controversy and
should not be called a sport. So I am proposing
another entity take over the judging. I would call
it the World Wide Federation or WWF for short. The
WWF would setup a training facility for not only
skaters, but also the judges that rate them.
I think Governor Jesse "the
Bobblehead" Ventura would make a great trainer.
His years of experience in that other federation,
the name escapes me right now, would be invaluable
in training the judges and skaters.
I would then hire heavyweight boxer Mike Tyson
to teach sportsmanship, former baseball player Pete
Rose to teach ethics, and the Westminster Kennel
Club judges, who chose that miniature poodle as
Best in Show last night, to sit on the panel to
take feces samples to test for drugs.
- Mandrake 8.1
-
I finally got around to installing the third of
three distributions I've been meaning to test as a
desktop replacement for Windows (the other two
being SuSE 7.3 and Red Hat 7.2).
By now, you probably should know what the
problems are with the current distributions and the
Dell GX1 that I have at work. Namely, the sound and
the MS Intellimouse. Out of the box, the embedded
sound is recognized, but not correctly setup.
Conversely, the mouse is not recognized nor
correctly setup.
Overall, I get the impression that Mandrake is a
conservative implementation of Linux. For example,
Ext2 is the default file system and you have to go
into expert mode to change it to Ext3 or ReiserFs.
In addition, it used XFree86 3.3.6 as default but
allowed me to switch to 4.1 (note, 4.1 caused all
of my default fonts to change to an almost
unreadable script font. I dunno why and using all
of the GUI based utilities to change it back no
longer work). Further, it uses the 2.4.8-26 kernel
(2.4.17 being the latest stable release at kernel.org) with
an upgrade to 2.4.8-34 possible (more on this
below).
In either case, for being so conservative on the
software, it is curious that the firewall they have
defaults to off. You have to go to the Mandrake
Control Center, Set Security Level, Firewall to
enable it. If you aren't already behind a firewall,
and are on a broadband connection, run, don't walk,
to this feature and enable it.
As in SuSe and Red Hat, Mandrake has a GUI based
update facility. It's called the Software Manager
and once configured to access one of many ftp
mirror sites, you can choose what RPMs to download
and install. Herein lies a strength and a weakness.
One of the updates was a move to the 2.4.8-34
kernel. I started by using the Software Manager to
download all of the available updates, including
said kernel.
It began the download and then installed the
software for me. Upon completion, it said not all
of the updates had installed correctly but did not
say what and where the problems were nor how to
solve them. Everything seemed okay though and I
went on my merry way learning how things work in
this distribution. When done, I shut down Mandrake
and booted into Windows. When I was done there, I
rebooted back into Linux.
Or at least I tried to. The only thing I saw on
the screen was "Linux loading..." Sigh. I suspected
that one of the problems was the installation of
the new kernel. So I booted off of the install CD
for Mandrake, hit F1
when the Mandrake opening screen came up and typed
in "rescue " (without
the quotes) and hit enter. This creates a Linux
system running in memory and mounts your drives so
you can access them and try to recover (in command
line mode). It also says to do a
chroot /mnt , which I
did, but sorry, I don't know why I needed to do
that nor what it does.
My first stop was at /etc/lilo.conf to see what
was in the configuration file. As far as I could
see, using less
lilo.conf , it was unchanged from
the original. Now, this is not optimum and is not
the way Red Hat did it when I updated the kernel
under that distro. The way Red Hat did it was to
create a new entry, while keeping the old (and all
the related software that goes with it), so that
you could boot into the older kernels, if needed.
Since the Mandrake update apparently did not go to
completion, I can't say for sure if that's how it
would have done it, all I can say is it didn't, in
my case.
From there I went to /boot directory to see if
vmlinuz-2.4.8-26.1mdk, which has a symlink from
vmlinuz was there. Doing a ls
-l to list the files indicated both
were there. So I went back to /ect/lilo.conf, used
vi to edit the file (vi
lilo.conf ), and then used
/sbin/lilo to
initiate the changes I made in the config file. At
that point, lilo gave me an error saying something
was wrong at line 13 and couldn't find vmlinuz.
Hmmm. I go back to /boot and do another
ls -l and it lists
both vmlinuz and vmlinuz-2.4.8-26. Well, I'm just a
newbie in this here parts so I decide to remove
vmlinuz (rm vmlinuz )
and create a new link to the new kernel that had
been downloaded by the Software Manager. I do this
by typing in ln -s
vmlinuz-2.4.8-34.1mdk vmlinuz . I go
back to /ect/lilo.conf to delete the changes I made
and then do a
/sbin/lilo to
initiate the changes. This runs to completion
without error so I am somewhat optimistic [fool
that he is - ed.]. I reboot, ejecting the Install
CD, and Mandrake came up fine under the new kernel
[wiping the beads of sweat off of my brow).
Having confirmed that everything seemed to be
running, I then reformatted and reinstalled
everything just to make sure I was back to a known
state. I'll be familiarizing myself more with
Mandrake, but given the problems so far, I think
I'll go back to Red Hat.
To sum up the general differences so far, SuSE
is a relatively stable, but not very up-to-date
distribution. They do not do a very good job of
keeping up with new versions of software and the
writers of these new software do not generally do
RPMs specific to SuSE, something, due to the way
files are scattered all over the place, you really
should use. They also don't provide free ISO images
for download for the x386, something,as far as I
know, most other distributions do. I guess their
business model does not include giving away their
work.
Red Hat, on the other hand, makes an effort to
keep relatively, but not bleeding edge, up-to-date.
And of course, many software companies release
their newest in default RPM format so it is fairly
easy to find what you want in the format you need.
The downside is Red Hat 7.2 is not very stable.
There are all kinds of bugs in KDE and XFree86
which cause strange interactions. This feels very
much like Windows 286 when it first came out.
And finally, Mandrake. Not very up-to-date and
not very stable. Two bad marks against them. Yes,
this is only my experience and what you get may and
probably will be very much different from mine. But
there you go. I can only write about what happened
to me, if you have a different experience, feel
free to let people know.
To sum up, I don't think any of the three
distributions are yet ready to act as a desktop
replacement for Windows. There are bugs in
everything, including printing and fonts, that
cause me to pause and say good try, but no cigar.
At least, not yet. Perhaps in a year. Until then,
I'll probably settle on Red Hat and use that to
experiment with. YMMV.

One of the ways of looking at the phenomena we call
the Internet is to think of it as a conversation.
To the extent that it is, one wonders why you hear
so few female voices speaking. I mean, while it's
nice to be among the boys, talking about manly
things like fast computers, cars, and women (why do
I keep hearing voices singing "He a lumberjack and
he's okay
...."), it's also well to get a different
perspective on life.
When you get the chance, go over to Jennifer
Balderama's site for a look (see it here).
Some of the stuff she writes is like a kick to the
chest by Bruce Lee - after you finish gasping for
breath, you want to tell all your friends you've
just been kicked by Bruce farking Lee!
Especially check out the right-hand side of the
page where she has links to a series on her dad
(Dad 1, Dad 2, and Dad 3). If what she has to say
doesn't move you, then check your pulse to see if
you are still among the living because she
rocks.
This is what the Internet is about. Not
SPAM, not get quick schemes, not sites trying to
sell the latest in hair addition/removal. It's
about a community. It's about communication among
the members of that community. And finally, it's
about being honest and sharing who you are.
Have a Great Weekend Everyone -
Aloha!
