Odd Tracking File Recording

Every time a Vista 3 node is shut down without going through the initiated shut down process, there is a chance of incorrect data written to the tracking files (in NodeA/tracking/). Normally it leaves strange characters or partial lines at the end of the file. This is the first time I have seen it write the contents of another log instead of the tracking data.

Even better. The node went down on June 5th at around 3pm. The lines from the other log were from April 23rd at 8:58pm.

Why am I surprised to see new incorrect behavior? Especially when the node was really confused?

Relative Truth

Found an interesting comment on an article the state of Georgia observing the Confederate Memorial Day….

The truth of history means very little to those who are dead set against learning anything from it. No matter what the history books used in our public school system say, most will never believe anything other than their own opinion about the Civil War. History revisionist are the celebs of the day. As long as people like Rev. Wright, and David Duke exist, history’s truth will be filtered through lies and distortions. Few observe Confederate Memorial Day: UGA to display original constitution; state offices closed

Truth may very well be completely relative. Back during the US Presidential election, I ran across an interesting article in the Washington Post discussing research John Bullock did about the effects of misinformation and idealogical bias ties. I used to think it had to do with a handful of people stuck in their green, second ammendment, pro-life, pro-choice, capitalist, regulation views. My favorite pasttime in college was assuming positions contrary to others even when I agree with the others.

I doubt the effect solely affects conservatives as was proposed in the article. More likely everyone has some blindspots in determing truth from myth or fiction kind of like optical illusions. (Yes, even myself.) We have to choose which information to believe any time we interact with information. Much of the rules in philosophy and science are built around combatting the biases we have.

Rather than force ideas on others, I think we should be teaching children from an early age to recognize when others and most especially themselves are operating under a bias. Its the only way to find detachment.

Athensdating.org

Writing a Blog Post About This Scam I noticed a little black and white sign: “Single? athensdating.org” a while ago. A couple weeks ago it came up in conversation. Today I saw it again. So I visited the site.

First impression: A local site should have images to represent something about the locality. Generic stock photography doesn’t cut it for me. The signup for wanted my home and cell phone numbers.

That sounded phishy to me.

Domaintools.com is a great site for looking up who runs a site. If the owner has selected privacy options with their registrar, then that would be a snag. Fortunately for us, the owner of athensdating.org isn’t hiding.

Owner: NuStar Solutions

The note “Email address is associated with about 4,690 domains” caught my eye. So I looked up NuStar and found this article about these popping up everywhere. (At least DomainTools gave me the info in one shot without having to do the same extensive research.) Lots of stuff online about these signs, who is placing them, and whether or not this is a scam.

I’m just going to assume it is a scam.

Resolutions For 2009

  1. Read 10,000 pages of science, economics, health, history, or policy books. For 2008, it was read 25 books. This year, I thought to change it page-based as the previous one shied me away from larger books. Two 350 page books vs one 700 page book shouldn’t be a concern. See Reading for last and this years’ progress.
  2. Be more social. A lot of will power is required to force myself to attend social events. Over the years it has only gotten worse. Before it reaches the point of requiring professional help, I probably ought to change my habits.

Useful resolutions to me are things I realistically can and will accomplish applying moderate effort. Making too hard of a challenge will result in giving up too quickly. Making too easy of a challenge will result in doing something I would do anyway. Last year was the first time in a really long time I even bothered other than using 43things to make some goals I rarely have met more by accident than any real intent.

Some resolutions I would pick I already do to the extent I realistically would….

  • Take the stairs and walk more. I already do these as far down the exercise more resolution as I realistically will go.
  • Eat better. I already mostly avoid red meat and eat lots of green vegetables.
  • Spend more time with family.

There are resolutions I would never actually keep without support from family and friends I don’t really have to keep me honest and stick to the narrow path….

  • Less fat, less sugar, no soda, no sweet tea.
  • Exercise more.
  • Finances.
  • Organization.
  • Less time spent in front of the TV or computer.
  • More blogging.
  • I already do not smoke or drink alcohol.
  • Get a Master’s Degree.

Hmmmmmm… Resolutions are bad for your health?

I haven’t checked my blog in a long while.


Followup on resolution #1. Apparently I did not followup on the 2nd?

Division Issue in YAPB

Problem PHP in Yet Another Photoblog causes “Warning: Division by zero in exifReader.inc on line 859” (the problem line is in bold):

 

case TAG_SHUTTERSPEED:
  // More complicated way of expressing exposure time, so only use
  // this value if we don’t already have it from somewhere else.
  if ($this->ImageInfo[TAG_EXPOSURETIME] == 0){
    $sp = $this->ConvertAnyFormat($ValuePtr, $Format);
    // Temporary Workaround for divizion by zero problem
      if (!empty($sp[0])) {
        $this->ImageInfo[TAG_SHUTTERSPEED] = (1/exp($sp[0]*log(2)));
      } else {
        $this->ImageInfo[TAG_SHUTTERSPEED] = 0;
      }
    }
    break;

 

Looks like YAPB is attempting to create a value if one doesn’t exist for TAG_EXPOSURETIME by inventing a new value. In my problem picture, the exposure time is 0.003 seconds which != 0. So why is the ($this->ImageInfo[TAG_EXPOSURETIME] == 0) condition evaluated as true? 

Interestingly, just prior to this is some code dealing with TAG_EXPOSURETIME which seems to be affecting this. Changing the 0.5 to 0.0005 (less than my current value removes the problem.

case TAG_EXPOSURETIME:
  // Simplest way of expressing exposure time, so I trust it most.
  // (overwrite previously computd value if there is one)
  $tmp = $this->ConvertAnyFormat($ValuePtr, $Format);
  $this->ImageInfo[‘h’][“exposureTime”] = sprintf(“%6.4f s (%d/%d)”,(double)$tmp[0],$tmp[1][0],$tmp[1][1]);
  if ($tmp[0] <= 0.5){
    $this->ImageInfo[‘h’][“exposureTime”] .= sprintf(” (1/%d)”,(int)(0.5 + 1/$tmp[0]));
  }

  break;

With this conditional, the exposure time is “0.003 s (1/400) (1/400)” without “0.003 s (1/400)”. Didn’t see a reason to have it twice, so I’ve dropped it.

Also, I figure it would be better to call ImageInfo[‘h’][“exposureTime”] instead of ImageInfo[TAG_EXPOSURETIME]. With this change, it seems to have resolved the issue for me.
