Punched card
A punched card or punch card is a piece of stiff paper that can be used to contain digital data represented by the presence or absence of holes in predefined positions. Digital data can be used for data processing applications or, in earlier examples, used to directly control automated machinery.
Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. Many early digital computers used punched cards, often prepared using keypunch machines, as the primary medium for input of both computer programs and data.
While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still use punched cards to record votes. [Wikipedia]
A few months ago I was crawling through the Canada-France-Hawaii Telescope (CFHT) data and found this very nice dataset of the Draco Triplet. I decided to download it for later use.
Now I processed the data and this is the result of the processing. As far as I know this is the image of the Draco Triplet with the highest detail ever shown (at least I couldn't find any imagery with more resolution).
The imagery was taken with the 3.6m telescope. Five images per channel were used:
R: 5x200s
G: 5x200s
B: 5x750s
Altogether that is 1.6 hours of exposure taken with the Megaprime cam.
Dataprocessing of this data is quite difficult because the camera consists of 36 CCD's that all have different behavior and gaps in between them. To get a good image all gradients have to be taken out which shows to be quite hard.
A few years ago I was crawling through the Canada-France-Hawaii Telescope (CFHT) data and found this very nice dataset of the Draco Triplet. I processed it then, but I thought with newer software packages it could be done better now.
Now I reprocessed the data and this is the result of the processing. As far as I know this is the image of the Draco Triplet with the highest detail ever shown (at least I couldn't find any imagery with more resolution).

These poor quality Data Charts are loaded with Reporting And Recording System Artifacts.
The plots are of date and time of processing and recording. They are not the dates and times of death. There is a big difference. If system artifacts such as no data being processed on Sundays were corrected, we might not need seven-day averaging plots.
The CDC and/or the NY Times should be doing data recording and processing system artifact removal.
I could teach them how to do it. Perhaps I should submit a proposal for a contract to do the work.

This is me shortly after joining the U.S Navy in 1976.
Toward the end of my service they went back to the old crackerjack uniforms which, I was so happy that they did. I loved those old uniforms.
My dad wore this old style crackerjack uniform and that's what I wanted too. I was a happy Navy man indeed.
I got this photo taken in San Diego Ca. while on shore leave. They provided me with the uniform because I was in my civilian clothes at the time. It was one of those special photos places you can dress up any way you want to.

I have been very busy outside of Flickr for the last few months, several very important projects have been keeping me from posting here. Here's a bit on an insight into what I've been doing.
Back in 1986 when I was in 2nd year computer science, we were introduced to the programming language awk - you can use it for all sorts of tasks involving the processing of data files...
The first feature that makes awk especially useful are it's pattern matching capabilities known as regular expressions, for example search for the first word on a line, or find a word starting with "article" followed by 5 digits and so forth.
The second most important feature is what is known as an associative array. This is a very convenient and practical way to create an index of something...
What we have to do is read in some files, looking for certain patterns at certain places and then change this around somewhat to make the information somehow more useful.
Back then none of this made sense, but over 20 years later I still have my well thumbed copy of Sobell's A practical guide to UNIX System V from 1985 and applying this knowledge is how I earn my living.
We don't use awk (or it's cousin sed) so much any more, it's been generally superceded by Perl, but we still owe a heavy debt to pioneering work from the 60's and 70's.
