Corporate accuracy?

I've been fiddling around with synchronization problems.  Notes on one device are not being updated on other devices.  While working on this problem, I've had to give a password.  Of course, I used the wrong password.

As part of resetting the password, I've been told by Apple that someone has been using another device to reset my password from such and such location.  On one device, I was told that the location was near St. Cloud MN.  I'm in Duluth MN.  Later, on a different device, the location was near Chicago IL.

Gosh!  What if I lose my iPhone?  Will Find My Phone tell me its in Chicago?

This is corporate accuracy or efficiency???

The simple done with difficulty

Years ago I bought a Timex Ironman from a jewelry store: a $50 watch from a store that would rather sell me a $500 watch.  It is one of those multi-function watches, and I think I used every one of them.  Also it is very accurate.  I think that it would gain about three seconds a month.  I was very annoying in telling people that whatever clock they were using was off.

Twice the battery wore down and I went to the same store to get a new battery.  The second time the clerk was not too happy about replacing it.

The watch is starting to get old and most of its functions are on my iPhone.  The best feature is that I don't need to dig in my pocket to check the time, I just hold up my wrist and pull my sleeve back.

Then suddenly, on my way to our cabin, the screen went blank.  At some point when I didn't want to be outside, I decided to pull the battery out myself and later buy a new one at Walgreen's.  I did have a set of small screwdrivers and set to.

I got all the screws out but the back wouldn't come off.  I had to repeatedly slide a pen knife under the back to loosen it.  Once I got it off I was confronted with a mechanism I didn't understand.  There were two tabs with arrows closely that indicated that they should be pushed towards the center.  It never budged.

I gave up and put it back together.  I think I only dropped one of the tiny screws once.

Yesterday I took it to Walgreen's and two friendly clerks worked on opening it up.  The first deferred to another who more experienced.  The second easily exposed the battery, went to the rack to get a replacement, put it in, and closed everything up, without dropping a thing.  She proceeded to reset the time, but I said I could do that later.

My cost, $6.25 for the battery!

When I got home, I tried resetting the time, but I couldn't get the next button to work.  Hoo boy!  Shall I just give up on the watch and purchase a cheap, time only watch?

Today, I thought if I took the mechanism out, then I could push on the next button directly rather than the button on the case.

I successfully took the watch apart again.  I don't have any small screwdriver at home, but I was able to use the blade of my pen knife as a screwdriver.  I was right that pushing the next button directly did work.  I reset the watch to the current time and proceeded to put it back together.

I got three screws in, losing them only twice on the floor.  The fourth screw just wouldn't stay upright in the hole.  I don't know how many times it fell to the floor, a floor with a rug whose nap is bigger than the screw!

I asked my wife to try with her smaller and more dextrous fingers.  She too dropped the screw a few times.  I went to the cold, cold garage to get a magnetic wand from my tool box.  I made a swipe over the floor and heard a tiny click.  There was the screw.

After a few more tries I was able to get the last screw started in the last hole.  Of course, it didn't seem to set right.  I loosened the other screws, tightened the last screw, and then tightened them all.

Well, I hadn't set the time as exact as I wanted.  But guess what, the outside next button worked!

I reset the time as close as I could to the time displayed on my laptop, a time that is synced with a standard clock somewhere.  I can't quite look at both times easily, but I would say that my watch is two seconds or less behind the actual time.

I'll see how much it diverges in a month or two.

Once again I can be a time pain; "that wall clock is off by…"

Gas attack or missile attack: who suffers?

I sent the following webmail to Pres. Obama:

To paraphrase your words: “At what point do we say we need to confront actions that are violating our Constitution?”  “I would argue that when I see 400 children subjected to missiles, over 1,400 innocent civilians dying senselessly … the moral thing to do is not to stand by and do nothing.”


What guarantee do you have that each cruise missile will hit a military target?  What guarantee do you have that each military target will be occupied by those responsible for the gas attack?  Do you know how many civilian workers might be in each target?


A Tomahawk missile has a supposed accuracy of 10 meters.  Many streets in Damascus are less than 10 meters wide.  Will every military target be more than 10 meters from an apartment building?  How far will the debris from a missile explosion go?  How many missile explosions will bring neighboring apartments down?


Assume one apartment building has six floors, each floor has four apartments, each apartment has five residents.  That's 120 residents in a single apartment building.  Do you have any count of how many apartment buildings will be brought down by any misses or near misses or "non-misses"?


If the lethal blast range is 28 meters, then eight neighboring buildings could be brought down. That could mean over 900 residents could be killed by one Tomahawk missile.


If you send ten Tomahawks that could mean over 5,000 Syrians will die for your "message" to Assad.  That is a rather high-price for a message for the deaths of 300 or 1400 people.


Oh, by the way, have you considered the repercussions if any missile damages a mosque?


And if the gas attack was perpetrated by Islamic radicals, you really will have been suckered!

Circular search for poll results on what you know and what you watch

I followed up on my suspicions of the poll results in "Quote of the day - Fox 'news'" by clicking the link from "No News Is Better Than Fox News, Finds Mean Old Science", Don Hamel, Addicting Info, 2012-05-23, to "updated study from Fairleigh Dickinson University".  That page gave only two of the questions: “Which party has the greatest number of seats in the U.S. House of Representatives?” and a question about the deal linking the payroll tax cut and the Keystone XL pipeline.

At the bottom of the page is a box containing "Methodology, questions, and tables always on the web at http://publicmind.fdu.edu."  That takes me to the home page of Public Mind.  The links for each reference to the "What you know depends on what you watch" study take me back to the same PDF file.  My suspicions are still unsatisfied.

I'll send links to this blog to publicmind@fdu.edu.  If I get in additional information, I'll post it as soon as I can.  Then we may see how well we fare on this poll.

Update: I received a reply from Public Mind.  See "More info on poll linking knowledge with news source".

Quote of the day - Fox "news"

"Fox News is to information what Big Macs are to weight loss."
- "No News Is Better Than Fox News, Finds Mean Old Science", Don Hamel, Addicting Info, 2012-05-23

As cute as this quote is and as intriguing as the poll may be, I'm suspicious of reading too much into the results.  The average correct answers were under two, out of nine questions, whether the respondents got their news from Fox News, NPR, or Jon Stewart's Daily Show.
