The beginning of the end …

Sam,

This blog is now going to become quite a different thing.  I had
really hoped that I was going to be writing about your growth and
development … which it is.  But for the foreseeable future it is
also going to be where I document the beginning of the end of my
marriage to your mother.  I want you to knowt hat I love her a
lot.  I always have … from when I first saw her … and I always
will.  She is a beautiful woman, and is very intelligent … and
funny … and fun to be with.  Her creativity abounds.

The divorce that we are about to go through has little to do with her
directly … it is more about your step-brother Joe, and her inability
to see that he could really use some help.  He is a very smart boy
… but almost too smart for himself.  And he has been raised to
respect very little in this world … which is very sad.

I have lived for several years now looking for a way to really make a
difference in his life.  I really wanted to see him turn the
corner.  As he turned 13, things just continued to get
worse.  His behavior at school, and at home, continued to
demonstrate what occurred as an entitlement to anything and everything.

I want to say that I am the one who chose to end the marriage.  I
chose a life where I did not have to live with Joe in the house …
behaving the way that he does.  Your mother simply did not want to
stop his talking back, his attitude, and his constant disrespect. 
I am not sure why.

On Monday of this week – April 18, 2005 – your mother ran away with
you.  She had talked to the school, and to Utah Dept. of Family
Services, about Joe … and both of them advised her that Joe was a
real problem.  For some reason, she then chose to pack up the car,
take you and Joe, and go to the bank.  There, she took all of the
money in several bank accounts, and then ran.

I called her that night on my way home from a class in Salt Lake City
to ask where I could meet her so that we could play.  I wanted to
take you to the park … or to find a place to play in Park City. 
She told me that she wanted me to leave the house … and then that she
was taking Joe to yourt grandmothers house.  I begged her to meet
me … I asked her to allow me to see you.  She said that she
would drop off Joe and then head back to the house.  She said that
she would call me right back … and never did.

The last time that I saw you was Monday morning … it is now Friday
night.  I miss playing with you … fighting and wrestling in the
front room … watching Baby Einstein.

I’ll write more … and I know that I will see you soon enough!  I
love you and I will make sure that you know that!  I will do my
best to make sure that we all get through this with an incredible
future!

Photon Processors already?

Along with other accelerating aspects of technology, of course
processors have to keep in step. There has been a recent trend
towards “mulcoth” architectures … multi-core, multi-threaded.
This is where a single “chip” that is placed in your computer might
actually contain “multiple cores” (multiple processors) and that these
processors would then provide “multi-threading” or “hyperthreading”
within them. What this give you is the equivalent of a
multi-processor machine inside of that single chip.

Much of the progress towards “mulcoth” processors was due to heat
issues as we continue to push up the speed of processors. So
instead of one giant “even faster” processor, you’ll be using machines that have
multiple cores … or multiple processors … running at current speeds in that one chip in your
computer.

I caught this article that shows where we are going to begin to track
the progress of newer approaches to breaking the speed limit on
processors. Photon Processors.

Look out … the future is coming quickly …

Towards the 1TB (Terabyte) disk drive

Wow … the doubling continues. There are two key points that I
like about this article. The first is that 500GB PC disk drives
will be on the market this year. That is now 100,000 times the
capacity of my first hard disk drive that I ever had! The 100,000 times growth in capacity has occurred in less than 30 years.

The second key point is that it shows no sign of stopping. From this article:

Desktop drive capacity will top out at around 1 terabyte by late 2006,
before running into technological problems in maintaining data
stability.

We are on track to again double by the end of next year! It is
difficult to image that common, and eventually commodity, hard disk
drives will reach these sizes. That is a huge amount of
data. In addition, as humans we will simply solve the tough
problems and continue the growth rates with newer technologies.

A last point is that there are currently numerous solutions – the most
popular referred to as RAID – that allow you to aggregate multiple disk
drives into a redundant array that appears as one, even larger, disk
drive. I have been tracking solutions like this over the years to
mentally track the cost of a terabyte of storage. I am now
stunned that in the next year, I might be buying one terabyte of hard
disk storge in a single PC disk drive.

PC World: PC Drive Reaches 500GB.
Demand for greater capacity continues to rise due in large part to a
growing need for music and video storage on PCs and consumer
electronics devices. To meet that need, storage vendors are turning to
new recording technologies. The first of these, perpendicular
recording, will debut from Toshiba this year. [Tomalak’s Realm]

More and more language …

Lately, Sam’s vocabulary has increased, and the complexity of the
things he says are really cool to hear.  We have been watching a
lotof the Baby Einstein DVDs, and adding adjectives and adverbs to all
sorts of nouns.  He also recognizes so many things …

We went to the park in Midway the other day and had a blast. 
Running around and around … up the mini rock wall, down the
slide.  The slide was generating a lot of static, and so we were
also shocking each other and the metal parts of the playset.

I realized how out of shape I have become … he just about wore me out!

In and Out of Bed

It’s been fun.  For the last month, Sam has been getting out of bed by himself … and back in! 
The getting out actually started a while back, however it has been
amazing that he will now sometimes get some toys, put them in his bed,
and then crawl back in with them.

The other day Tracy came in to tell me that he had got out, put his
large toy garbage truck in the crib, and then crawled back in to take a
nap.  Very cool.

EnOcean … impressive combination of technologies …

A friend of mine Dave Cline just sent me a link to EnOcean. 
This is a very impressive company that is leading the wave of the
future when it come to distributed sensor networks.  They have
addressed some of the key elements of a successful solution:

  • No Batteries – the sensors create energy from their environment
  • Wireless Communications – they sense and send their data
  • Mesh Networking – they use a hierarchical mesh networking system

This is some very impressive work, and ought to get people thinking about what is going to be possible soon.

Anti-Spam and what to do today

Posted on by

It seems that anti-spam is, of course, all about verified
identity.  I really liked this article, and it got me looking into
what I can do on my mail servers today.  I realized that there are
things I can do when I read this quote:

Reports indicate that as much as 50 percent of sending domains are
authenticating their outbound e-mail using SIDF and signatures.

Wow … am I behind the times!  I went to Google and did some searching.  I found a great blog talking about SIDF where there are the following links describing where to read more and what to do.

The first link is the Microsoft SenderID page that has a lot of information.  It also has a link to this SenderID Overview Presentation that gives a great overview of the concepts and how it works.  The last link is to the Microsoft Sender ID SPF Record Wizard … which will assist in creating the actual DNS records that you have to configure.

All of this is oriented towards telling the world that your mail server
is the legitimate source of mail for your domains.  Time to add
more identity information about my mail server into DNS … I’m
creating my SPF Records right now …

Up2date e-mail notifications

A while back I had started to experiment with a way to get e-mail
notifications from my servers when up2date detected that new packages
were available. I am running a series of Fedora Core 1,2, and 3
boxes and it seems that the updates come quite frequently.

I decided that this weekend I would sit down and write a new bash
script that could be run daily by cron. Here’s what I wrote:

#!/bin/bash
# First lets check with up2date …

# have up2date list the available packages …
up2dateOutput=`up2date –nox -l`

# now check to see if packages are listed …
firstUpdatePackage=`echo “$up2dateOutput” | grep -A1
“\-\-\-\-\-\-\-\-\-\-” | awk ‘{if (NR==2) print $1}’`
# take the
output,
# grep for the long hyphen divider
# grabbing that line and the
next line,
# awk the second line to see if there
# is a package name at the
beginning

#echo “First package: |$firstUpdatePackage|”

if [ ! -z “$firstUpdatePackage” ]
# there is a package name
then
  #echo “Sending e-mail …”
  nodeName=`uname -n` # get the host name
  mailSubject=”Up2date – “$nodeName
  # create the e-mail subject line
  `echo “$up2dateOutput” | mail -s “$mailSubject” root`
  # send the e-mail to root
fi
exit 0

So far, it appears to do exactly what I had hoped … an e-mail notice
when there are packages that can be updated on my servers!

AJAX and Smart Clients

Posted on by

I always think that it’s funny how people want to say that it’s
either/or. As someone who has been working with AJAX application
development for years, I’ll say that AJAX has it’s share of
issues. At the same time I’ll say that I can’t understand why
more web sites are not using AJAX!

AJAX provides a very rich and usable interface for web-based
applications. As both Internet Explorer and Mozilla/Firefox both
now support extremely rich DOM interfaces, and lots of support of lots
of standards, most web sites could be offering a lot more functionality
to their visitors. Another huge advantage of AJAX is impact on
servers. A good developer can take lot of load off their servers,
and improve response time, by pushing more computing down to the client
machine.

Smart Clients, however, are the future for many applications.
This is most evident with e-mail … probably the most ubiquitous
“Smart Client” application on the planet. We run our e-mail
application, and bring all of the mail down to a cache on our local
hard disk. We can read and write e-mail any time and any place
… connected or disconnected … and later synchronize to the servers.

In any case … it’s not about either/or … instead both of these
models are simply enhancements of what we are already using. Both
AJAX and Smart Clients are going to be with us for a while!
