 9-12-2011 __ Light rail open house / Penn Broadway  . 
The open house last weekend (26 hours over 3 days) sponsored by Northside Transportation Network
seemed to be successful at helping many people understand the LRT proposal near us better.  I
learned things during the 8 hours I spent there. Nothing like trying to explain something to
deepen one's understanding.

One question was about how many houses alternatives D2a and D2b would take. I think D2a would
take several houses near Broadway to make room for north bound car traffic on Oliver to rejoin
Penn before intersecting Broadway.  I wonder about having Oliver extend more staight up to
Broadway (tho the actual intersection should be at right angles to facilitate access to/from
east on Broadway.).  To help examine this I extracted these two images:

Our block circled in blue on part of Damage map

Personal notes:
Wed May 25

The storm track was sw to nnw and the closest damage to our house was
about 2 block west of us with many uprooted trees, a roof blown off
some windows smashed and shingles blown off.  May be worse damage
north of us.  We had no damage tho our power was out from 2:15 pm cdt
Sunday 5/22.  Power was restored across the street east of us Sunday
evening. Ours came back Monday evening.

Even not having electricity seems like a major hinderence to normal
functioning.  It sure demonstrates how dependent we are of
electricity.  Even finding phone numbers is crippled tho I had a 10
year old printed phone list. Nothaving net access at home is a pain too.

We sent stuff from the freezer compartment in coolers to Becca's work
where she has a fridge.  She got a ride to work with our neighbor Sam.
We have great neighbors which helps a lot.

Thur May 26 10:30 am

Finally on Thursday I've found a way and time to get full net access
near home.  See below. I've decided to create a blog entries...  Probably
not formatted too well since I'm not at my usual computer... The Wednesday
entry was hacked together from an email I'd sent.

We still do not have net access... Just discovered that my little
green computer OLPC XO-1 that I rarely use (and my only laptop) is
working - battery is suspect and green fully charged led never comes
on) but after botting it says it is 99% charged. Mpls wireless node 3
blocks from my house (penn & plym) is working.  So I am sitting at bus
stop online...

 3-17-2011 __ Drive by huge gas main fireball near I-35W  .
On the way to the airport this morning southbound on I-35W we saw huge flames ahead.
At one point they appeared to be over the Russian Art Museum in the former church on west side at 50th St.
Aerial image of gas main fireball clipped from KSTP TV segment that shows location just west
of I 35W on 60th Street.  Fortunately there is a cub parking lot to the north and a pond to the south so there
was little nearby to catch fire.  Some parked cars got scorched paint, melted rubber.  Glass at cub broke.
There were no injuries. The first images available that I found were Youtube video from fellow on the way to work
Both I35W and Hwy 62 freeways were closed for a couple hours shortly after we went by.

10-07-2010 __ Exhaust system problem  .

The connection on our old (1995)  Saturn between the catalytic converter
( "catcon" ) and the tailpipe was corroded to the point the bottom bolt
no longer held it together. ( ~1/8" gap). I looked for a way to get it
repaired that might last a year or two until a vehicle with high enough
fuel efficiency becomes available here that we'd be happy with. Possibly
the all electric Nissan Leaf which my friend who is converting a
pickup to run on batteries says looks promising.

I consulted several people and places about the exhaust problem.

Saturn would only replace the the catcon and the tailpipe for
about $500. The catcon is particlularly expensive to replace.

Midas would cut out the bad connection and attempt to weld in a short
piece of pipe to bridge the gap ( $50) but warned that if there was not
enough metal left in the pipes to weld they may have to replace the
catcon (with a generic one) and pipe ($350)

I stopped at an auto parts place and they suggested that one could cut
out the bad connection and clamp in a short piece of pipe to bridge
the gap.  (Tho others warned this would likely leak a bit and make some
noise.

I consulted two local friends.  My 80 year old neighbor
thought the clamped solution might be ok.  I considered doing this
myself but getting the car up to work on it would be a problem and
weldiong would be better.

The catcon and exhaust pipe seemed to be otherwise in fair shape
I banged on them with a cold chisel and they seemed fairly solid.

Here's a picture of the area of exhaust system that failed
(The green lines are where the bad part could be cut out and a new
piece of pipe could be clamped or welded in place.)

I decided to have Midas attempt to weld in a new piece.  When they cut
out the bad connection (about 3.5" long) with a sawzall one could
see that the pipes were in good shape and they predicted welding in
a piece about 8" long would weld ok.  It seems to be fine.  At my
request they also welded in a rod across the main hanger for the
system  to reinforce it. It was quite rusted.  Total bill $57.50.
I was quite pleased the service from our local Midas shop

10-03-2010 __ PBS rebroadcasts  .

An email message I sent today.  If I get a response I'll update this line.

Dear TPT / PBS etal ** ,

It took me several days a couple sessions digging on the web to
finally conclude that the episodes of Scientific American Frontiers
being aired on Twin Cities Public TV (TPT) currently (Oct 2010) are
indeed from 2005 - 5 years ago.. My first step was to consult
Wikipedia which indeed said "until the show ended in 2005" but given
the nature of Wikipedia and the way most TPT and PBS web pages talked
about the show, I still thought maybe these were more recent episodes.

Finally I found  Scientific American Frontiers archives
and by searching for the episode titles there I found the
associated dates in 2005.

While the episodes are surely still interesting information, even the
descriptions imply a timeliness aspect.  For example the episode
Friday 10/1/10 :

 Surgical Slimmers
 In spite of the risks, people are lining up to solve their weight
 problems in the operating room. And if the latest device - an
 implantable stomach "pacer" - works out, millions more will be taking
 the surgical way out.

"Latest device" is obviously subject to no longer being true and
by now there is probably evidence whether it "worked out".

I am not complaining that TPT is airing five year old shows but that
the dates they were produced is not readily available.  Why can't
TPT and/or PBS simply include production dates with program schedules
and descriptions?

Long time PBS watchers like myself are aware that shows get re-aired
and may have been produced some time ago. But in this case I was
truely confused.  and if youall were more forthcoming about dates, I
think viewers would be truely appreciative.

When one reads a book one does not assume it was published a few
months ago but with TV, I think most people expect shows were recently
produced unless otherwise indicated ( or on PBS ? ).  With books
the publication date is recorded in a very standard and easily
accessible way.  Production dates of PBS shows should be similarly
accessible.

Thanks,

Fred

02-28-2010 __ Record icy streets in Minneapolis this winter  .
This was originally a Jan 17 email to a friend
Subject: Re: Why our streets are worse the Hibbing's

Minneapolis streets have had a lot of ice and snow this year. The city
has imposed a parking ban on the even side of residential streets till
April since the space between parked cars was getting so narrow that
fire trucks could not get thru.

The following are my explanation of how this happened.

I suspect the difference (between Minneapolis and Hibbing that accounts
for Minneapolis' worse condition on streets) is temperature.  It was
above freezing on Xams day but got cold and then very cold after that
before the streets got plowed.  That along with packed show from traffic
meant we had icy snow by the time the plowing got done which is much
harder to plow.

In addition to the temperature, another big factor was the timing -
holiday and weekend and consequently no trash pickup with which alley
plowing is coordinated. In adition there may have been some postponement
of plowing (I dont know this for sure) in order to avoid multiple "snow
emergencies" and still get it all; that is wait til it stopped snowing to
plow.

And of course there was also the long cold spell afterward - about 3 weeks
not getting above or even near freezing, often -10 degrees F meant that
the frozen mess could not be easily removed.

Another complication was the combination of snow/water that came down
after the last shoveling (few of us shoveled in the wee hours as the temp
dropped) The resulting thin frozen slush layer was slippery and over time
got polished and more slippery.

On sidewalks that had not been shoveled foot traffic made foot steps of
packed snow that became frozen irregular surfaces that are hard to walk
on. In alleys and side streets traffic on unplowed streets made for deep
frozen ruts.  Some plowing furrows at intersections became frozen barriers
to the first plowed roadway.

All of this resulted in a near "perfect storm" of factors to make for a
mess.

From:  Wikipedia Perfect storm article
 A "perfect storm" is an expression that describes an event where a rare
 combination of circumstances will aggravate a situation drastically.

Feb 28th update (message to Whomail - neighborhood mailing list)

The street drains on both sides of 12th Av N just west of Penn Av (by
Lincoln Peace Garden that we maintain )
were totally covered with ice and snow and as a result water several
inches deep across the street extended nearly a half block west.  My wife
and I used a pickaxe to open them up yesterday.

Anyone else have lots of standing water on streets?

Next summer I'll make notes on the exact location of drains around us
to make such tasks easier...

March 18 update.  The one side parking ban was lifted in early March.
We've actually had relatively warm weather the last few weeks
Snow and ice is virtually gone from streets and are laaargely dry as
are sidewalks. A few big piles of snow and
shaded areas still have remnants of snow.  The bike path thru Wirth Park
has a bit of snow left in spots and running over it in places
We have a record number of pot holes. Bike lanes and other places have
lots of sand and gravel till sweeping gets done. Temp today was in 60's.

10-28-2009 __ Light Rail Transit (LRT) on streets   .
I've created a web page about North Minneapolis Transit
Maybe I'll get this blog entry integrated into it some time...

There is currently a proposal for the Bottineau Transitway going North and West of downtown
thru or around North Minneapolis and then on out along Highway 81.  Public info sessions have been
held recently. Construction is probably 10 years away if it ever happens.  Tho the Penn Av route
would make crossing Penn Av and driving on it less convenient, I think that alternative is
clearly preferable because the stations would be much more convenient and therefore used
more by North Minneapolis.  I think it also offers suprior development potential for North Minneapolis.

The official Bottineau Transitway has a lot of information --
so much it is easy to be overwhelmed or lost.  The recently posted "Alignment
Alternative Concept Drawings" are very detailed and useful about the route but they are huge.

Monday I took my recumbent bike on the bus and LRT ** to the VA Hospital station
of the existing Hiawatha LRT line that goes SW from downtown to the airport and Megamall to
look at the LRT layout there.  On the two blocks north of E 54th St the tracks are
in the middle of the street with one car lane on each side. This resembles how I think
Penn Av near our house would look tho on Penn there would be only one wider one-way south
car lane on the west side of the tracks.

Note that cars cannot cross the LRT between 54th and 52nd but pedestrians can walk across
(AFTER CAREFULLY LOOKING BOTH WAYS) but this is discouraged. The electric powered trains are
quiet so do no depend on hearing them.

Open Street Map of LRT route north of VA
Google map (Satellite view) of LRT route north of VA (Note that LRT not show between 52nd and 54th
and Minnehaha is mislabeled "Hiawatha". Zoom and "Street View" allow closer examination.

Olin Crossings illustration of 6 multifamily housing building they are developing north of E 54th St.

South of 54th the LRT is on the West side with two way traffic on the East and
the tracks are on crushed rock and have a fence along them.

I started a custom Google map of the route with "pins" color code like the maps on page:

I've started drawing lines for the "D2" (Penn Av) but have not goten taht done as of today.

What's an LRT "car"?  Note that "cars" are 94 feet long and articulated. There
are two doors on each end on each side. Trains can have two cars and soon (when
stations have been expanded) 3 cars per train.

10- 5-2009 __ Navigation problems...  .
Yesterday I bought a used Sun EZ-Speedster CX Recumbent Bike from
Jory in Carver, MN. See entry at Used Sun EZ-Speedster CX Recumbent Bike in Fred's bike blog

I had multiple navigation problems resulting in a half hour delay
getting to his house.

In reviewing my problems on the trip out, I concluded that there
were several main problems (note that I do not have GPS) :

1) No navigator; it's much easier when my wife Becca and I are together
so one of us can be following the map. I had to stop to consult the maps
and therefore did not do so very often.

2) Out of date labeling on maps I had.
 k) 2004 King's street map book pg 145 +
 m) Metro map on 2007 MN map
 g) hand drawn map from Google Maps
 o) OpenStreetMap.org ("osm" is kind of the Wikipedia (user contributed) map)
which I consulted today (not yesterday) OSM map that includes Jory's location

I had attended an introduction to osm a couple months ago but have not continued
to contribute changes to it or use it much.  It is not as good as Google in some ways
yet but could be customized by local people to have bikeways better than Google could
ever have, for example.

The new 212 was not labeled "212" on my maps the way it is now posted.
 212 IS correct on o)
Also the north south road just west of Jory's has various labels
 Jonathon Carver Rd (signs)  "11" on m) , townline Rd on g)
 "147" k) and o)

When I realized I'd missed the new 212 I stayed on 5 and turned south on
41 (after a few stops to check map)

I overshot old hwy 212 in downtown Chaska by a few blocks (it is no longer
labeled "212" -- now signed "Chaska Rd").  I recovered from this fairly
quickly but stopped again once I got on Chaska Rd til I decided
decided it was the road I should be on.

3) Detour around my destination with complications related to route names.

The turn onto 40 was closed with detour west to mislabeled 147.
I stayed on "147" till I got to sign for East Union when I finally turned
around. (I had suspected I was off course but did not know where I was...)

This time the other intersection with 40 which also was closed to thru traffic
also had a sign something like "historic Carver village".  I took that and
finally got to downtown Carver and found my way to Jory's with k)

 5-16-2009 __ Html aware wordwrap   .

I maintain most of my very simple web pages / html with TSE editor . Most
of my pages use "pre" "/pre" tags for the whole page. pre tags are
"preformated" and format lines based on the end of line characters in
the file. ( "Normal" html ignores eol char. and reformats lines based on
the setup.)

With pre tags source lines have to be longer if there are html tags
(like links) in the line since these are not displayed as long as the
source.

It would be nice if the TSE macro mWrapPara() (or similar) could treat
html tags special and wrap paragraphs containing them so RENDERED lines
are all about the length as determined by the TSE Right Margin variable.

 5-15-2009 __ DC-SC driving trip -- Mom's final hospitalization   .
~ 3/14 - 3/31/09 We drove to a family wedding in Greenville, SC by way
of Washington, DC with several visits on the way.  A great trip to a
part of the country I had never been in.

A few days after getting home, we went to Iowa for the weekend to visit
my mom in the hospital and I ended up staying about 2 weeks thru her
funeral.  My sister was there a bit longer.  Other family came too.

While she was in the hospital we did not know if she was going
to recover.  Seemed like she might but other times it did not.  A day or
so before she died we finally accepted that she would not recover and put
her in in-hospital hospice.

She was 90 and had a good life.  And a good death too.  The two weeks
stay with her in the hospital (my sister and I took turns staying all night)
was good in retrospect.  A long chance to say goodbye.

Since then I have made a trip back to Iowa to deal with her
financial affairs which she had made very simple but still the
experience of being her executor has been a challenge for me.  It's the
sort of thing which takes some time to learn how to do but I or most
people are not likely to use this knowledge more than once.

Maybe some time I will blog more here about these experiences.  I've
written lots of email about it to draw from. ( Two paragraphs added Oct '09)

--- About Ubuntu 8.10 ---

I had been using Ubuntu version 6.06 since it came out in June 2006. It
was a 'long term support' (LTS) version.  The next LTS version came out
in April 2008 but I did not get around to installing it till 8.10 was
available. I actually have both 6.06 and 8.10 installed so I can compare
them. It only takes about 90 seconds to reboot into the other operating
system.

I particularly needed to go back to see the many customizations I've
made. Unlike when I first made them I am trying hard to keep detailed
records of what and how I added such things to make it easier to make
them again next time.

A summary:

My /home (where Linux stores a user's data files) is effectively the
same partition used with version 6.06 by having links in my real 8.10
/home folder to sub directories of /home partition.

I aim to put very few files in /home directly ( I put them in
subdirectories linked from it instead). Software of course puts
configuration files in hidden directories directly in the /home
directory.   I intend to have a carefully selected set of directories,
preferably 25 or so main ones starting with digit 1 so they can be
displayed mostly on one screen one per line. I'd also like to have this
set of directories correspond closely to my bookmark folders.

Other links I add include: in / (root dir) to mirror directories of my
web pages (see f9m_) to allow urls like file:///fholson.cohousing.org .
Other links are for alternate/easier command line navigation.

I use tcsh as default shell since I've used it for about 20 years and
have never learned bash as well. I use the shell for some things (50% ?
) , GUI for some things depending on what I find easier. Generally
things I do infrequently (e.g. network setup, apt-get installs)for which
there is a good GUI alternative).  Some things are easier becuase I have
aliases and scripts for them.  Some things are done via TSE (editor) macros.

I like to have several terminals automatically set up for various uses
including one dedicated to ssh to my online shell account. (The GUI SSH
client now looks very useable but I see no need to switch yet.)

Firefox: Port bookmarks and a few other configuration tweaks. I keep an
automatically updated copy of my bookmarks on the web (password protected).

Ramdisk auto created on bootup (mounted as ~/l ) with near empty working
file: "~/l/temp" that I use for scratch pad.

Tho Ubuntu automatically installs* most standard applications I install a
few more including dosemu so I can use a few legacy programs including
my old dos based editor TSE ver 2.00, and the PAF genealogy program.
I also install a flash player*, gnucash, minicom pine, audio codecs* needed.
* Copyright issues prevent automatically installing some things :(
Installing other sortware is amazingly easy with the GUI Synaptic program
that uses apt-get packaging tool.

BTW today's Public Radio feature 'Future Tense' recommended a minimum
computer spec of 2 GB memory for Vista... I'm only using 512 KB with
Ubuntu 8.10 and have not noticed any problem.  I should upgrade anyway
since memory is so cheap.  Similarly, I understand 4 GB flash drives are
now available for $10

ALTERNATE SCREEN SHOT was made by viewing first screenshot (with Ubuntu's
Eye of Gnome image viewer) , rotated 180 degrees in full screen mode
and taking another screenshot. One of these days I'll leave it showing

11-23-2008 __ Bike rack prototype  .
I've been pondering a new way to haul groceries and such on the back of a
bicycle. Reuseable bags are starting to replace one time use plastic and
paper bags. Bikes with elongated frames (behind pedals) are showing up
that can carry more cargo, in part by allowing cargo to be further back
away from pedalling feet.

My design suspends two reuseable bags on the sides of the rack but moves
them back a few inches.  A piece of plywood attaches to a the top of a
typical bike rack and extends back and has two cross pieces that slip into
sleeves added to the bags. The cross pieces can be removed and stowed
parallel to the bike and the plywood can be slid forward over the rack
when not being used. The latter is needed to allow the bike to be maneuvered
vertically in tight spaces (like the garage) which I do often.  Here are 3
pictures of my prototype:

 8-29-2008 __ Growing Communities Of Scientists (GCOS) computers in classrooms  .

This summer I have been working with some Mpls science teachers
who are setting up a new version of their computer system IN their science
classroom / labs (to be more accessible than in typical separate computer lab.
2 students per computer to encourage collaboration, monitor under glass tabletop
so they do not impeded face to face interaction or use of other materials).
The old system used Apple computers suspended under the tables; the new system uses
10 year old pc's which function as "Thin Clients".

One of the 4 GCOS classrooms will be at Nellie Stone Johnson school (NSJ) here in North
Minneapolis - a much easier bike ride from my house than to Roosevelt HS where the other
classrooms are located.

At some point I hope to explore the effective similarities between GCOS and the OLPC,
One Laptop Per Child learning environment.

 7-19-2008 __ Wellstone Crash Site Memorial on the way to Bearhead .
This year we visited the Wellstone Memorial on the way to Bearhead State
Park where we go group camping.  On two previous attempts when we were
up that way we did not plan far enough in advance and did not find it /
take the right route.

The Wellstone Memorial and Historic Site is near the location of the plane
crash that took the lives of Paul and Sheila Wellstone and six others.

The crash site memorial is located about 4 miles south of Eveleth, MN and
about 3 miles East of US Hwy 53 on Bodas Road (County Hwy 95). Hwy 95
intersects Hwy 53 about a half mile north of where State Hwy 37 goes west
from Hwy 53.  All of these Hwy's appear on MN State map. You will see
signs On Hwy 95 for the site and directions for parking.

The new lab will be using an Ubuntu Linux "thin client" system with older, readily available
computers acting as terminals on a central server.

Reading blogs for the first time, one lacks context.  Often and "About" section is absent or
does not provide much context.  One way to gain context is to read / browse older entries.
Trying to read older entries in chronological order -- is a bit of a challenge.  You have to go
to the oldest entry you wish to read; read / don thru the entry then to read the next, scroll
up to the beginning of the preceding entry and read down, etc. I'm beginning to rethink the use
of reverse chronological order for entries in blogs and archives. I used this order when I set
up the Archives of Cohousing-L after the last reorganization / move in 2004.
This order clearly has the advantage of putting recent entries at the top of the page.  But
following a sequence on messages - recent or otherwise - seems unnatural with "rev. chron."
order.  I have been using "blogs" on my computer (not online) to keep notes etc on various
topics.  Many on my top level folders have a "start" file that includes a blog.  I've recently
pondered converting them to chronological order but have a very easy way to "get to" the (top
of) the most recent entry...  This online blog, like all my web pages is basically a very
simple web page that I maintain with a text editor.  For a while I've been thinking of having a
an index to entries here.  But now I'm thinking that I may reverse the order too.

While I'm at it, a couple things about blogs (that use blog software ) that bug me:
Often they do not have an adequate (IMHO) introduction / overview / profile / "about" page.
This may be that the blogger simply has not set that up or it may be that the software does
not provide facility for it.  Second I'm surprised how often no email contact for the blogger
is provided.  Maybe they figure any contact with the blogger should be via a comment / response
to a blog entry but some times a private note is more appropriate and I prefer to do that by
email.  One reason I prefer this is that a copy of my message ends up in my sent mail archive
where I can more easily find it.  If more blog comment forms (and web contact forms in general)
provided the option for sending a copy of messages left to the sender, this would reason would
be reduced. (Tho such copies end up in the inbox instead of the sent mail where they are harder
to find ( bigger haystack to lose them in.)  Many blogs these days provide an option for an RSS feed
which is helpful for following new entries.  I don't currently use RSS, I prefer to get a
brief email message saying there is a new entry. Some how finding how to set this up is harder
than setting up an RSS feed.  Sometimes it is not offered, sometimes it is obscure how to
set it up.  Maybe we need a new term / icon like "MSS" (Mail notification simple setup).

I continue to show the One Laptop Per Child laptop to interested people (see earlier blog entry).
The Walker Art Center has an exhibit currently "Design for the Other 90%" of mostly practical designs
for the third world - shelters, water carrying, human powered transport etc.  They have two OLPC's
on display - under glass with a nice little write up.  On their family day on Sat, I plan to take my
OLPC and show it.

 5- 2-2008 __ Our "mystery weekend" trip to North House Folk School .

4/23-25/08 we went on a "mystery weekend' that Becca planned without Fred's involvement.  She
got Fred to consent to the dates well in advance but otherwise did not reveal details tho some
slipped out. She signed us up for classes at North House Folk School in Grand Marais, MN on the
north shore.
Fred: hands on solar electricity
Becca: twig chair building.

In order to attend a bike trail meeting (about Cedar Lake trail to the river under the new
stadium) Thur night before the classes that started at 9:00 am Friday, we left at 3 am Friday.
Worked fine and we missed the fog other folks encountered Thur night. We stayed in a 5 unit
little motel two blocks up the hill from the folk school that happened to be owned by the
instructor of Fred's class. While there Fred used the net access at the library a few blocks
away (twice - mid day Friday and Sat).  He also showed the OLPC XO to folks but was only able to
get connected usefully once.  Becca took Monday off to give plenty of time to get home.  We came
home by way of Grand Rapids where we visited a very distant Brackett cousin who we stay in touch
with.

 4-30-2008 __ Python (computer language) book / MN Barcamp .
Yesterday I found an online book that I plan to read:
_A Byte of Python_ by C H Swaroop
> This book will help you to learn the Python programming language,
> whether you are new to computers or are an experienced programmer.

While reading about the book I came on reference to Barcamps.

From Wikipedia, the free encyclopedia:
 BarCamp is an international network of user generated conferences
 open, participatory workshop-events, whose content is provided by
 participants  often focusing on early-stage web applications, and
 related open source technologies, social protocols, and open data
 formats.

 I plan to go to the Barcamp here in Minneapolis on May 10th: MinneBar


 4- 7-2008 __ Playing with webcams .
Last weekend I played with webcams i.e. searched for and looked at webcam pages in locations where friends live etc.
I created this page (by extracting html for the webcams folder in my bookmarks and modifying it and adding comments.
Fred's links to webcams

I intend to add to bookmark and my webcam page the time between updates for some more of the
webcams.  Update time varies from 1 sec to one hour (and broken ones that "never" update).

Some webcams have "control" options pan, zoom, update time.

Idea: Have a non-default option to open new updates in a separate
browser. This might be implemented at the web site (with a way of
selecting the option.  Or maybe there is a way to implement it the
brower end which would allow it to be done with any webcam.

 4- 5-2008 __ Final spurt of winter 07-08 ?   .
This winter seems to have hung on and on. Repeatedly I've said I hope this is the last cold spell.
And Sunday, Mnday Tuesday we had up to 8+ inches of snow. The temperature was around or a bit above freezing
and warmer weather was predicted so it was a wet snow (about an inch of moisture) that was not expected
to last long.  Some people did not bother to shovel tho I did.  Here's a couple of pictures:
Russell Av N after snow (in new window , compare)
Russell Av N a few days later
Note that the first picture had the date stamp "03/31/2008" (which I overwrote)
turns out that for months the date/time in the camera had been off by 12 hours...
It felt a lot more like spring the next day tho there was more snow left than show in the after picture.

 3-24-2008 __ Singapore, Hong Kong and Taiwan   .
I've never been to Asia. My knowledge of that part of the world has long been lacking.
In particular I realize I confuse Singapore, Hong Kong and Taiwan.
A friend is moving to Singapore for 3 years for a job and I decided to summarize a bit of
research here. As usual I turned to a map and Wikipedia. See eastmap.htm

 2-24-2008 __ I WON a little One Laptop Per Child ( OLPC) laptop  .
It looks like a toy. Wikipedia:Olpc
I won it at the Linux meeting I went to yesterday (see prev
blog entry for details about linux group). The goal of this education program is to
get one of these kid friendly devices to kids everywhere in the third world so they can have
a powerful education tool that can access the Internet.

Fred's OLPC page / links

A few highlights: Picture of OLPC 'XO-1' laptop      With features labeled
o hardware design goals:rugged, low cost, long battery life laptop.
  Modest performance accepted to get this.
o 433 MHz AMD Geode LX700 cpu
o no hard drive - 1 Gigabyte Flash drive, 256 MB ram (currently) 3 USB ports
o innovative dual mode (backlit-color/sunlit-monochrome) LCD display
o built-in wifi with ability to access / serve others
o rugged, downsized (about 9x9x1.25 inches), moisture resistant membrane useable keypad,
  low/flexible power requirements including solar and hand cranked options coming,
  relatively environmenatlly friendly
o Special Linux based evolving, upgradeable open source software that uses collaborative
  learning environment metaphor gui instead of just usual desktop metaphor with numerous
  built-in applications - "activities". Gui hides filesystem which is frustrating to experienced
  computer users since it seems (is?) less flexible.
o goal of mass production at $100 per laptop in 2008 in support of...
o goal is universal education of world's children via access learning to communities and
  to the Internet using purpose built laptops

I plan to study and use the laptop to promote the idea, demonstrate it to groups.
I may even USE the laptop as my portable computing capability (I don't have another
laptop tho my son does (Mac) and my wife may get one ( MS Windows for work compatibility :(

The Timeline of ideas that led to OLPC starts with the introduction of Logo, the first
programming language written especially for children.  I tutored kids in math / Logo in the
early 1980's here in north Minneapolis.  The activities include "Pippy" an intro. to programming.

Update: 3/24/08 I've learned much more about the OLPC, shown it to many people and will be giving a presentation
at Penguins Unbound Linux Group meeting in May (last Sat). Here's a page that summarizes the XO nicely
David Pogue (NYTimes) video / Eric Pettifor review
I've been invited to write an article about it for a local community paper.
Note that the "Wikipedia:Olpc" link at in above is about the organization; the "$100 laptop" link on that page
is a detailed wikipedia article about the XO laptop.

 2- 1-2008 __ Fred gets community wireless net access  .
See also Keeping 'em down on the farm in the computer age

Yesterday (1/30/08) I finally upgraded from dialup access to the net.
I'd been waiting a long time for the Minneapolis municipal network . Recently
the phase of the build out by USIWireless was completed in my area. Earlier
this week I signed up on line after consulting their techs about a few
details (I wanted to get the Ruckus modem (model 2211 , ruckuswireless.com )
that has external antenna connection in case I ever need that (units
with this feature had been expected but not shipped until recently)).
Currently there is a 'rubber duck antenna' connected here which is used
along with the internal directional antenna system. The external Ruckus
connects to the computer via Ethernet so no drivers are required.

I fashioned a "shelf" that supports the Ruckus near the top of a window
on the back of our house where one can see the
USIW node we use at 12th and Sheridan Av N across the block.

I got the 1Mb/s package for 2 years for $240 special deal (2 years for
the price of one year's month to month price / 50% less than regular
cost of annual payment price) I purchased the modem for $80 (it can be
rented for $5/month).

I'm using Ubuntu 6.06 currently and I had no problems using the USIW
and performance has seemed fine. To put things in perspective tho,
1Mb/s is not particularly fast but compared to dialup it is fast.
Compared to fiber to the door it is slow; see first 'related link' below.
For me the cost/performance tradeoff is for my needs the best available
here that I know of.

    <=100 ms        Great, typical of a high-speed cable or DSL connection.
    100 to 200 ms   Good, common for cable and DSL connections.
    200 to 400 ms   Fair, usually seen with dialup connections or faraway sites.
    400 to 600 ms   Slow, either the connection or the remote site is slow.
    600 to 1999 ms  Poor, high latency. Typical for satellite connections.
    > 1999 ms       No response, the ping was blocked or the site did not reply.

There seems to be more latency in response when I first fetch a web
page from a site than when I access additional pages at that site.
Does this have to do with lookups that have to be done initially that
are cached for subsequent accesses that I never noticed before?

Practical example of improved performance
I have an archiving process for my listservs ( justcomm.org
that I perform the first of each month. It fetches a bunch of many html
pages with wget (non interactive content retrieval from web servers) and
extracts selected info to text files on my computer. I did that today
and it took less than 11 minutes instead of the 26 minutes using
dialup on Jan 1.

 UPDATE 10/16/08.  I've been using Mpls wireless for 9.5 months now and continue to be fairly
pleased with it. I continue to get about 1Mb/s download tho I don't check it often; right now I'm
getting 700-800 Kb/s (I was getting 1.5 Mb/s initially but that was a benefit to compensate for
other initial shortcomings) I think there have been two outages that lasted hours to 2-3 days
due to equipment failure / weather, USWI provided temporary dialup access during those periods.
I continue to have SSH disconnects tho the frequency has dropped off from about daily to only
twice in the last two weeks.  The problem may be a software issue on my computer related to long
ssh connections.  I's been easier to tolerate than investigate so far.

I still think radio is not the best solution for the last mile problem; I still dream of having
fiber optic cable all the way to my computer but for now I think the cost benefit of Mpls
Wireless is hard to beat for my needs.  I also think the main benefit is not speed tho that is
certainly an improvement over dialup.  The "always on" nature is the most useful - no waiting to
connect or grouping net uses for the next time I am connected.

One continues to hear anecdotes about people having poor performance from USWI at their
residence but it is quite difficult to get a balanced picture of the degree of the problem.  I
have concluded that performance is quite location dependant but do not have enough experience
with enough locations to conclude how widespread inadequate performance is.

I have used the USWI roaming from various places in the city some with the OLPC.
It seems to be quite location dependant but often works fine.


12-15-2007 __ Wikipedia is a great resource  .
I find Wikipedia to be a very useful source of information.
Tho it can potentially have less than valid information due to it's open collaborative nature,
I find the information to be better and more useful than say TV ad, TV news, TV generally.
To find useful information on it requires much less sifting than using Google (tho of course
there are still topics that Google can find info on that are not in Wikipedia.  I've been surprised how
useful Wikipedia can be for current news sometimes (with background available if one needs it
and of course much less repetition of the same main points).  I'm thinking of making a monetary contribution.

10-26-2007 __ Note to community station KAXE on MN Iron Range  .
Sent via KAXE talk back

Good morning from near north Minneapolis, the home of US Congressman Keith
Ellison.

I've been listening to KAXE a bit via the Internet lately and appreciate the low bandwidth
24kbps mp3 stream which works over a dialup connection. It works pretty well and I can use the
net for other things at the same time as long as I don't use too much bandwidth. We are still
waiting for the municipal wireless system to get installed in our part of town.

We went to the five year memorial of the Wellstone plane crash at the College of  St Catherine
last night and blogged a bit about it {below!}

Thanks KAXE, keep up the good work. Fred  fholson.cohousing.org

10- 6-2007 __ Banking hassles related to computers  .

I don't currently use online banking except when I'm using MS Windows
somewhere away from home. (I try to keep my computer free of software
produced by the monopoly Microsoft.) My bank http://franklinbankmpls.com/ *1
has online banking that I can not / do not currently use it from my
computer (Ubuntu 6.06 Linux / Firefox 2.0.0.7 browser see Fred's system).
This is because of several "hassles" (numbered below based on chronology).

I have never used online banking extensively (my "offline banking" is
easier for most things). About the only thing I need online banking for is
to look up the image of a cleared check once in a while. In the US it
seems banks no longer return cleared checks - maybe if you pay an extra
charge.

Hassle #1 The online banking requires the pass word to change
periodically - with about the same frequency as I use online banking so
I have trouble keeping track of the current pass word.

Hassle #2)  I get an error when I try to log in with their "new improved
security" feature. I can't get past an error after entering my username.
Curiously I can log in using Firefox running on MS Windows! Also curiously
I was able to get logged in and use the system from my computer when I
FIRST used the "new improved security" system.  There may be a workaround
by always telling the system I am a new user - I have not pursued this - I
don't need a another hassle.  Of course the support folks generally
consider the problem to be with my computer not using Internet Explorer;
I consider it their software's requiring IE...

Hassle #3 Not online banking related.  On the bank statement (we may be
unusual in that we reconcile our records with bank statements) debit
card transaction entries are poorly structured.  They lack a something
like a check number - a sequential id by which entries can be ordered
and identified. This means they are not listed in a very useful order
and hard to identify. Theoretically the transaction date could serve
this purpose but the various dates related to a transaction (actual time
of transaction, time transaction gets reported to bank etc) vary enough
(a few days) that it is not very helpful.  Also the payee is identified
inconsistently.  I try to record the address *2 when I use my debit card
since that is sometimes listed in the statement. Debit card entries also
have alpha numeric information that is meaningless to me but which takes
up room - enough to spread the info so the entries take multiple awkward
lines each.

*1 I am generally quite pleased with Franklin Bank . They are relatively
small - enough to give me the impression that they can legitimately
offer "personal service". They have a great record of service to the
community and other public spirited programs and such.  I think the
hassles above are largely out of their control and based on vendor
software.  They probably are not big enough to have enough clout to
effectively pressure vendors to fix their lame software but this blog
entry is part of an effort in that direction anyway.  Anyone know of a
bank that supports Open Source software ( http://www.opensource.org ) to a
reasonable extent?

*2 Sometimes I have a debit transaction with only an address that I do not
recognize so I google the address and can sometimes figure out the store name.

 8- 2-2007 __ Interstate 35W bridge collapse  .
I had this note about the I-35W bridge collapse on the top of  .
Fred's link page ( fholson.cohousing.org)  for most of August

 SPECIAL NOTE 8/2/07  None of my family or any one I know (so far) was on the I-35W
 bridge when it collapsed at 6:05 pm on 8/1.  We use that bridge occasionally but not
 often and not often at rush hour.  I do bike under a section (north end) that
 collapsed ** sometimes when I am headed over toward the Dinkytown area by the U of MN.
 Andrew will be living in a dorm about two blocks from where I bike under the bridge.

** Turns out this was wrong the section over 2nd St SE did not collapse tho some adjacent sections did.
The section on the other side of the river over the parkway and bike path did collapse.

Three images that summarize the collapse:

( Note: the images open in new windows so you can come back to this window to open the second and third image and then go back and forth to compare.) Middle section of collapsed bridge on the day after the collapse, as seen from the nearby 10th Avenue Bridge, looking north. This picture is from http://en.wikipedia.org/wiki/I-35W_Mississippi_River_bridge As of 8/21/07 small version of picture is shown in the upper right corner at: Disaster_response section of Wiki article. Collapsed bridge looking south on the evening of the collapse. North end of the bridge A freight train was traveling under the bridge when it collapsed. Note that tho this is the "North end of the bridge" there are more elevated sections of the approach to the left of this image - one of which had one end collapse so it rested at a steep angle. Also that the tall building on the left is the dorm (Sanford Hall) where Andrew will be living for the 2007-8 school year. Note that all three images have some common items which help relate them. There is a big straight truck with a red boom and "clamshell" bucket on a partially collapsed section of the approach on the north end of the bridge. There are also long white train cars under and west of the truck in all three pictures. computerworld.com article New Wi-Fi network proves critical in Minneapolis bridge disaster UPDATE Fred's I-35W replacement bridge construction archive of close shots on 6/18/08 7-19-2007 __ Environmental impact vs price of production .

That is use Flash puter technique even when using Nano6... 2-10-2007 __ Mike Casper passed recently, We'll go to funeral in Northfield . Mike was a buddy and collaborator with Paul Wellstone. Like Paul we knew Mike after Becca's days at Carleton related to the 1980's reincarnation of the Farmer Labor Association. History of the 1930's Farmer-Labor Movement Found while googling to see if there is a physical memorial to Paul in N'fld: 0) Mike Casper's funeral (see http://northfield.org/node/2585 1) Abt Paul's Memorial's political result: http://www.collegenews.org/x2886.xml 2) They love Paul back in NC: http://www.unc.edu/news/archives/oct04/wellstone100604.html I presume Mike's funeral will maintain decorum but with Molly's spirit recently in turmoil (see below) who knows. Update: h2m_ It did maintain decorum - more or less, some subtle comments during funeral reflections from about 10 people. The reception afterward was a great opportunity to catch up with friends and acquaintences and swap stories and meet some folks. The goodies Becca baked and brought got their own little table and consumed. The catered food was great. There is no memorial to Paul in Northfield presently. I have two modest proposals to remedy this: 1) A Carleton Classroom dedicated to Mike Casper (and Paul Wellstone) Maybe the classroom in the framed picture of them that was at Mike's funeral reception that has Paul informally dressed sitting on table at front with big smile and big gestures while Mike stands nearby in suit with his arms folded and a somewhat more reserved smile. That picture should be on the wall of the memorial classroom. Other considerations for which classroom are accessibility and open on weekends. 2) Some sort of plaque dedicated to Paul Wellstone (and Mike Casper) at a spot in the Arb, maybe on the route they typically ran, Maybe a site that resembles the crash site (where Paul's US Senate re-election campaign plane crashed in 2002). h6c_ Today I stopped by Paul and Shiela and Marcia's grave - in the northwest corner of Lakewood cemetery. The memorial stone with carved epitaph on it's irregular natural shape reminded me of Olof Palme Monument stone in Stockholm that I visited in 1999; it has his signature carved in it. i7j_ See also Wellstone Crash Site Memorial 2- 1-2007 __ Feb/1/07 I mourn Molly Ivins passing too soon. . see http://en.wikipedia.org/wiki/Molly_Ivins The above was at the top of my email "signature" from Feb 1-11,2007 8-22-2006 __ Learning to modify that Open source . My approach to computers has always been from low level software up. That is I like to know how things work, often create my own solutions from simple tools that I understand rather than use a more complicated tool that I dont understand in depth. This is partly because the Forth language that I used was oriented this way. Another influence in this was my first personal computer - a 6502 based single board Sym. The Sym had an "open" "monitor" - prom based 8 Kbyte 'operating system' callm "Mon". Mon was provided with complete source code and ram based pointers to key functions (initialized at boot) that allowed one to redirect those functions to ones own routines. For example one could write character inout routines to get them from a full keybard rather than the default keypad. My text editor with flexible macro language has allowed me to solve many problems that go well beyond basic editng. But it is not always possible. Software and operating systems have gotten more complicated Since I started using computers back around 1970. Along comes Linux. Linux, based on Unix is a very large and complicated system. Particularly when used with a GUI like Gnome. On the other hand the "Open Source" philosophy makes it theoretically possible to write or software change to suit one's preferences. My guess is that very few people actually do this much tho scripts, command aliases and many configuration options allow much customizations which I have done. Tho I've been quite happy with Ubuntu Linux that I've been using for a couple months, the terminal program has one feature that can be annoying. I've decided to try making a minor change to that program as an exercise that will involve learning some C programming in the Linux / Gnome environment. I knew this would be a big undertaking but various unexpected hurdles have come up and gotten solved but I still have a long way to go. I decided to blog about the exercise here in case it might be helpful to others. My first step was to post a note to the gnome on July 17, 2006 and got some useful replies particularly Don Scorgie's. See archived note I also had some off list correspondence that came from this post including Don's reply about my asking for more info on API's: An API reference is basically a list of functions and constants within a library. This allows you to see what a function actually does and what parameters can / should be passed in to it. There are various gtk+ / gnome API references for the different libraries available at: http://developer.gnome.org/doc/API/ They can also be viewed offline using devhelp (although, I don't know how to set this up or use it). In the code, any function starting with gtk_ is from the gtk library, g_ come from the glib library and gnome_ are from libgnome library. The glib library also has an object system (gobjects) that are used by GNOME to make C more object-orientated. The reference for these functions etc. are split out from the main glib docs to a separate document (gobject). Looking through the gnome-hello code, it appears most of it is gtk / glib calls. There is a couple of other calls (at the start of the main function to bindtextdomain etc.). These are calls to set up internationalization stuff. Other than this, all the functions should be listed in the glib / gobject / gtk documentation. I'm reading the C book at: http://publications.gbdirect.co.uk/c_book/ ~8/20 Cant "find" GCC...

Sometimes when I write email the ideas start flowing and evolving and the recipient gets a longer message than I probably should have sent them. But if the ideas have merit (sometimes they do I hope) it may be worth it. Below is such a message generalized a bit to set the context for presentation here. Gnome is an easy to understand desktop (graphical user interface including many tools) for a Linux or UNIX computer. Gnome is Open Source Software (OSS), roughly that means developed and maintained by a vast range of volunteers and there is no charge to use it. I am using the current version of Gnome which came with the OSS operating system Ubuntu version of the GNU/Linux. Open Source Software is an alternative to the proprietary and often monopolistic software including Microsoft. Date: Mon, 17 Jul 2006 00:21:32 -0700 (PDT) From: Fred H Olson fholson@cohousing.org To: fundraising@gnome.org Subject: Idea: optional info "about" Gnome Friends Hi, I've just been browsing the http://www.gnome.org/ site (I think for the first time). I'm very impressed (with version 2.14 which was released recently as well). I had an idea that I decided to share with you.. I think recognition of Friends ( contributors ) is great - we all like to be appreciated and this is a great way. How about offering Friends the option of listing something about themselves e.g. o home location (encouraged) o a few words about interests o a url or email addr (preferable: url to page that has email) All this would be limited to what could be displayed on one line in columns (that were retained when captured) for sorting. Remember all is optional. A couple thoughts on displaying of Friends It might be nice to be able to list all friends in one page (till that becomes impractical :) with a tag for what years they contributed at what level. Having this sortable by location would be neat. If all years are not in one page some way to search all would be nice. One last thought, the folks who work on Gnome as volunteers deserve recognition as well. Maybe monetary contributors and work contributors could be recognized in an integrated list. Of course some are both. I lied, on more last (blue sky) thought. Gnome is not the only OSS project that people can contribute ($ or wk) to and it is unreasonable to expect any one person to contribute much ($ or wk) to multiple / many deserving projects. Therefore maybe someday there could be an integrated OSS member / $ or work contributor recognition system. I lied again, one last even bluer sky idea. OSS is only one part of a bunch of alternative better visions for the world to which people can volunteer $ and work. Maybe someday we can have an even broader recognition system. BTW in my chosen volunteer field ( Communications for Justice ( http://justcomm.org ) (using Mailman for good causes)), I dream of someday having some kind of "validated community participant" system that many different discussion and announcement systems etc could share the validation we now do usually on a per list basis (thru subscribe / confirmation email / response to complete subscription). This would allow one to choose what to participate in with a simple checkbox from a page (hierarchy of pages) once they had logged with their validated community participant (VCP) username and password. This came to mind since the consolidated contributor system and the VCP system might be usefully integrated. Obviously there are many challenges including privacy and trust issues. But one needs a vision. Dream on. Sorry this message got way out of hand... Feel free to forward it to whomever if you feel appropriate. Keep up the good work. 6- 6-2006 __ Fred's computer system - (This entry updated periodically) ** .

For several weeks in March modem problems . kept my main computer offline and therefore few of my web pages got updated. A few were updated online. Today I got this computer back on line and downloaded the few "updated online" files and then resynced accumulated changes made locally. At the same time I have been working on setting up a new computer with a new Linux distribution (Ubuntu) which will eventually be set up as my main computer and have the local copy of web pages. But all the little scripts, macros, command aliases, installed programs etc take a while to get set up, so it is easier to use this computer till that all gets done. 12-13-2005 __ Format modification / Radix 36 . I've added some html links to sections of this document to ease cross references... And other of other tweaks and updates. I decided "Radix 36" (used in my Date Code) needed explanation. The "radix" of a number system is also known as it's base. It's probably most easily understood by comparison to familiar systems. Note that the radix is generally expressed in decimal. Symbols used when radix is greater than 10 are letters of the alphabet. Decimal is base/radix 10 Binary is base/radix 2 Octal is base/radix 8 Hexadecimal is base/radix 16 a=10, b=11, c=12, d=13, e=14, f=15 Radix 36 is ... base/radix 36 a=10 ... k=20 ... u=30 ... z=35 I use radix 36 sometimes when I want a very compact way to encode and record numbers in ascii. 12-12-2005 __ The Rev Billy Stop Shopping Gospel Choir 'revival' was great . Yesterday we went to hear Rev billy and the Choir (www.revbilly.com There were about 25 people; most in red robes, two trumpets, electronic organ and drums. Rev Billy was in a bright white suit with his blond hair in a pompadour resembling what Billy Graham looked like in his younger years. Note that that Billy moved his organization headquarters away from Minneapolis a few years ago; the building is now a college building. Rev Billy's revival was a cross between great music, a revival meeting, a spoof, and a campaign for a noble cause - to resist the over commercialization of life to the detriment of more worthwhile lives. He even brought tears when he remembered Richard Prior and Eugene McCarthy who died the day before. The question was addressed: 'how can you really totally stop shopping?' which friends have asked. The Rev considered calling themselves something more moderate which would acknowledged that commerce is part of life but still addressed the rampant over commercialization in the US; but there is only so much that can be said in a name... Here's a nice picture of Rev Billy and a few of the Choir members This picture is currently on their home page. Note that their web page is updated often including blogs - check in often. There's already some references to their time in Minneapolis and pictures of the bus that was hit by a truck in Ohio. One group member is still in the hospital. After the show some people (tho not us) boarded their biodiesel buses to go to the Megamall in their 100 extra robes to confront the beast. A few observations: Sometimes it was difficult to understand the words of the singers. Unlike the usual gospel choir, the words are not familiar enough to understand despite a suboptimal sound system, loud instruments, echoes etc. A few measures come to me - lyric/song sheets tho this would reduce some of the surprises that add fun to the show and of course the words probably vary from time to time and place to place. A high tech approach would display the words electronically above the choir. A third approach appeals to me - something like Bob Dylan's video where he has placards with the main words that he discards as they are sung to reveal the next next placard with words coming up. This would require experimentation, practice and coordination to show words most usefully. The choir was maybe 20 percent African American, the audience seemed overwhelmingly white which is a bit ironic since it was at Sabathani Community Center which serves the Black community. This may have been in part due the way publicity was done (the publicity in Minneapolis was a problem). I wonder how authentic African American gospel choir's react to Rev Billy's choir. See the biography entry of James Solomon Benn -- Choir Director, Soloist' at Choir bios Here in Minneapolis most people had not / have not heard of Rev Billy and even after I had it was hard to be sure what to expect. I suspect "Word of mouth" could be used more systematically to encourage people who have seen the Choir to alert their friends who might have an opportunity to see the choir. Today I finally subscribed to the Choir's "bulletin" even tho it does not say how much mail to expect or indicate how I can get off again should I decide to. I previously subscribed to the Rev Billy Mailman list (so I could read the archives) and unsubscribed. It's very inactive. 11-23-2005 __ Are George Bush's lies finally catching up to him?

Listen to the report via link at: http://www.npr.org/templates/story/story.php?storyId=5024408 10-13-2005 __ Visually comparing two files by "flashing" between them. / Scanner lab . I sometimes like to compare two files - slightly different versions of the same document such as program source code so that I can spot differences down to an individual character difference in context. One way that I sometimes do this is to "flash" quickly between two files on the computer monitor to compare them. I have yet to implement a quick and easy way to do this short of only having two files open. It's a matter of coming up with a convenient user interface. see flash.s (TSE macros source file - on Fred's computer...) Update. I have implemented this tho the routine to pick the two files is still awkward. They include shift routines so both files shift one screen up, down, side to side (for long lines), home and end. I'm pondering an extension of shift routines to more than two files that compares all files open. Aside: About 20 years ago (~1984) I did some low level software work at the U of MN Astronomy Scanner Lab that implemented a computerized system to compare two images of the same location in space ( at different times). As I understand it, astronomers have long used mechanical systems to "flash" between two sky images so a human observer could easily look for noteworthy differences. The scanner lab scanned a large collection of images (and stored data in a special format that basically noted location of "bright spots"). Software compared this data in a way analogous to "flashing" between two images. The scanner was built on the base of a precision metal working machine that could move an image (a glass plate up to about one foot square) in two dimensions. The scanner moved the plate "raster fashion" so that strips (about an inch wide (?) ) were scanned by a laser and receptor system that sent a stream of data to the main computer - a VAX system at that time running Forth. Multiple passes of adjacent strips collected precision data for the whole plate. I worked on routines on a microcomputer that controlled the motion of the plate in response to commands from the main computer. 9-22-2005 __ Using Rsync to facilitate Web page management . I see it's been well over a month since I set this up and no entries.... (except for entry f9l_ whose date I faked to make easier reference to it...) It is not because it's difficult. Adding an entry is as simple as editing a file on my computer since "rsync" makes updating files online so easy. The system works something like this. o web pages are actually at my ISP (Tigertech.net) o on my computer I have a similar set of directories and files which are actually the "originals" and the ones at the ISP are copies. I have a small script (like an MsDos batch file) that calls a Unix program called "rsync" which very efficiently and quickly compares the original files and the copies and uploads differences. The script file excludes backup copies and certain other files that are in this directory structure. For a good introduction to rsync see Wikipedia on rsync which starts: rsync is a free software computer program for Unix systems which synchronizes files and directories from one location to another while minimizing data transfer using delta encoding when appropriate. o I have a command alias "rsf" which calls that script which makes it 4 keystrokes to insure that all local updates are moved online. Of course, I use rsf to update all the web pages in these directories that I maintain. And I don't have to be online to be assured that a change gets made to the online copy. The next time I am online and use rsf, if updates all files that have changed. 9-21-2005 __ 3 letter date code format . I've used it for years as part of 8.3 dos file names... Sometimes as the extension, sometimes as the last 3 of 8 char file name. Since the year comes first they sort into chronological order easily. Basically one char each for Year, Month, Day in fcd_ radix 36 with years starting in 1990. Some examples: 011 - 1990 Jan 1 357 - 1993 May 7th 9ab - 1999 Oct 11th eat - 2004 Oct 29th fcp - 2005 Dec 25th zcv - 2035 Dec 31st (date by which I'll have to have a new system - I'll be 84 years old.) 8-12-2005 __ FRED's COMPUTER Sept 2005 . As of 10/05 I'm running Linux exclusively on one of the last PC-AT format motherboards. I use a highly adapted MSDos based text editor under Dos emulation. Thus the "d:" drive designator which is really my Linux home directory. The editor is Version 2.0 of The Semware Editor (TSE) Version 2.0 is ancient (about 1995). A native Linux version is being developed and most TSE users use a MS Window version now. All versions of TSE have many convenient features including a very flexible macro language which can also be used to modify the editor functioning itself. See semware.com I use text to develop my simple web pages and maintain listserv records and email and numerous other files. I have some macros to facilitate some of these. Curiously I don't currently use some html writing macros that I do have. (12/05 wrote a simpler html aid macro that I use some.) I use use Rsync to facilitate Web page management (see f9m_ Using Rsync) This requires a directory structure that is similar to the one at my isp the directory d:\1html (aka in Unix terms: /home/fholson/1html ) corresponds to my www.cohousing.org (tho I do not maintain that web space). I do have several subdomains there which correspond to subdirectories there and on my system. Thus files accessed by TSE in: d:\1html\fholson appear on the web at: fholson.cohousing.org d:\1html\mn appear on the web at: mn.cohousing.org Tho the way it all fits together is a bit convoluted it really works slick. (again, see f9m_ Using Rsync) 8-11-2005 __ I will try a blog in my computer QBC format (see next entry below) . I'm going to try having a Blog that is just like the 'blog' text files I use on my computer extensively to organize text information in many files. This is mostly for my convenience since it is easy for me to create and maintain. The explanation without software to facilitate use of features is probably hard to appreciate. Sorry. 11-20-2009: I decided to hide my 3 character date codes and replaced them with regular format date codes. On my computer it is the quick browse links that are most useful. I have a root text file with links to other text files I consult and add to etc with varying frequency. The second level files often have links to other text files etc so the result is my personal web. Unlike the html files used on World Wide Web there is no separation between source and rendered version - everything is text files and everything is immediately editable. It's much simpler. It works for me. 8-10-2005 __ Fred's "QBC" format for text files . Note this entry originally included "FORMAT OF THIS FILE" but the blog has evolved so no longer uses this format. (Quick-browse, Blog, C3*_sections ( C3* means 'See 3 asterisks') Quick-browse: Links to other files of format ** {path/filename} Example: a link to Fred's Link page (on Fred's computer): ** d:\1html\fholson\index.htm Having a bunch of these makes maneuvering to desired information in other files much easier. See section about ON FRED's COMPUTER a few paragraphs below and f8c_ FRED's COMPUTER Sept 2005) Note: Files with qb links must start with a designator I call the "D-Path" : q: or // q: or (a TSE macro comment) <!-- q: --> (an html comment) BLOG: Log entries w/ most recent at top of Blog section with 3 character date code followed by 2 underscores and a space. ( References to log entries have ONE underscore) (see f9l_ Date code format) C3* sections: Lines with '***' tag important entries and sections. Commands (in TSE editor ON FRED's COMPUTER) to facilitate use of QBC format files: Open another QB file (full path preceded by "**" [F12][F12] Get picklist of BLOG entries [F12][7] (compressed view search for "__ " ) Get picklist of c3* sections [F12][8] ("*" w/o shift) (compressed view search for "*** " ) (Note that a picklist is easier to implement than point to point links and works pretty well as long as the number items is not excessive (as in case sometimes of Blog entries). It's also helpful if words in section headings (with 3*'s ) are in a similar format and not too wordy.) 1- 1-1970 __ Keeping 'em down on the farm in the computer age . This entry is really being written on Feb 1, 2008 but I've been observing this computer age phenomenon analogous to "How do you keep 'em down on the farm once they've seen Paris" since about 1973 at least. Basically once one has experienced better, faster performance of a technology for a task, it is difficult to tolerate the previous way of doing the task. A few examples: Old way New way Next way? black & white TV color TV HDTV 300 baud mechanical terminal 1200 Baud Video Terminal PC w/ large flat display 30 baud modem 1200, 9600, 14.4K, 56K, "broadband" Fiber to the door CP/M, MSDOS cmd line ui MAC OS, MSWindows, Linux w/ Gnome or KDE ? walk...bus...bike...car Gopher protocol HTML (Web) Text graphic/multimedia Sometimes there are significant drawbacks to a better/faster way sustainability e.g. private cars often high cost limits on future choices (locked in to proprietary software) Inability to customize, update, fix (proprietary software) Better way: Open source. Sometimes there are less obvious advantages of "old" ways of doing things, e.g. the exercise, low resource use, pleasure of walking and biking. The joy of seeing friends versus only electronic mediated communications. I think that "appropriate technology" takes into account these drawbacks and advantages. One can use a variety of technologies to accomplish some tasks depending on the specifics. For example, our household has one small car, many bicycles, lots of bus maps and we use radio, text messages etc to coordinate shared use, multipurpose trips, multimodal trips etc. To avoid some of the drawbacks I often resist the latest and greatest for a while. My frugal nature prevents me from being an "early adopter" in general. I typically use a computer that is a few years old design when I get it, I also tend to keep my computers for a long time (6 years - for 5 main computers in the last 28 years or so. First computer < Sym-1 (80)> Previous "Main" computers: Osborne ('81), 8Mhz Xt (87), Zeos 33 Mhz 486 PC (93), Cyber used 266 Mhz AT (99), Nano6 "ATX" (1.6Ghz AMD (06) In addition to these "main" computers I've had a variety of other computers and made upgrades to some of these including a new mother board on Cyber. I even used my son's MS Windows computer a fair amount at one time.
