July 1, 1997

How can it be July already?

Last months edition was a little light. What can you expect for free?
I'll try and be a little more verbose as the summer wanes and we move
into the fall. Stay tuned. I may also invite a few guest speakers
in.


Is it me or did June just fly by? I blinked and it was gone.
Perhaps it's the new job or maybe it's too much fast living in
cyberspace. Did you read about the woman who locked her children in a
room and spend 22 hours a day on-line with AOL? Let's just skip over
the obvious mental issues here and get to the really weird part. What
could be so interesting on AOL? No doubt this woman would have been
selling her children for cocaine if the calendar read 1981. I wonder
if she'll sue AOL for not putting warning labels on their chat groups.

Flying children on commercial airlines

On the two misguided occasions when we chose to fly across the country
with our less-than-five-year-old child (more on the 5 year part in a
second), we bought an extra ticket and used a car seat. The 'cabin
attendants' where very impressed. I thought it was common sense.
I've come to find out that people think carrying their children on
their lap and risking their lives is "saving money". I actually
heard a woman tonight talk about going on "one last free vacation" with
her child on her lap before the child was "too old". I had to bite
my tongue.


I'm a licensed pilot (general aviation) and commercial jets scare the
$%#%$ out of me. You can not afford not to buy an extra seat
for your child. If the plane hits "rough air" (what us pilots like to
call "light chop") you will not be able to keep your arms around that
35 pound mass. I can show you the law of physics which make this so.
No amount of caring or loving will change these equations. Buy the
extra seat. Use a car seat. Or better yet, stay home until your
youngest child has reached the age of five. That's my plan.


I was in a commercial plane the other day and had an unusual
experience during the takeoff. The pilot pulled the nose up, realized
he did not have enough air speed, put the nose back down, waited about
10 seconds and then "rotated" again. I thought I was going to wet my
pants. No one else around me seemed the least be worried. Sometimes
it's better to be ignorant. This episode would not have been that
noteworthy expect that the plane was 3 hours late taking off because
the crew had not had the required time off between flights. So this crew
might have been, shall we say, fatigued. Guess what the #1 cause of
airplane accidents is - fatigue combined with schedule pressure.

Java and Javascript - mutant half-brothers with no common DNA?

Has anyone out there tried to write a Java program which injected data
back into the HTTP stream? I understand the Javascript can do it. It
seems that making Javascript and Java speak is at best difficult and
at worst really clumsy. Why did Netscape have to call it JavaScript
anyway? It has nothing to do with Java at all. It they intended it to be
an integration tool for Java one wonders what their criteria for
success was.

The truth about NT

OK, here's the truth about NT.


  • It's wicked slow (even on my 266Mhz P-Pro II)
  • It needs a lot of memory (128mb)
  • The vm system does weird things and image activation fights with
    the file system buffer cache
  • It's not as reliable as UNIX


There. I said it. Please note that I've been using NT for a long
time and like it. I am at that crux where using NT and UNIX are about
the same. I used to be a huge SunOS bigot. Then I became very
NetBSD/FreeBSD oriented. Then I discovered SVR4 and Solaris. Most
recently I turned to Linux (a lot, and I like it a lot). But the truth is
that if I had to trust my job to an OS I'd pick Sun Solaris 2.5.1 and
run it on a Sparcstation. Sad but true.


I like NT but it is anything but crisp. It seems to eat memory for
breakfast lunch and dinner. CPU also. It also has these weird effects
where apps will just hang now and then. Who knows why.


And the DOS baggage. Can we please loose the DOS baggage? No more
"C:" PLEASE. Can't we all just use UNC file names and live in peace?
And while were at it, can we use forward slashes everywhere? Thanks.
I'll be using an editor with 8-space-tab-stops thank you very much.

Using NT as a router

Why would anyone want to do this? Is it just me? I recently
configured a nice little router from Compatible Systems. It was
inexpensive, high quality and it did not have a C: drive. Why would I
allow one of the 1,000,000 things which can go wrong on an NT box to
jeopardize my routing? Routing needs to be like the phone system -
always available. Also, good NT boxes are expensive - good routers
are not. I'd pick a nice little router box over NT.
