Chris Garrod, Chris Garrod is a retired geek, one of TheHumbleProgrammers, and was the Minister of Networks at the Institute for Geophysics and Planetary Physics He wandered in here in late March of Y2K and after he CorrectedTypos successfully, he became hooked on wiki. Later that year, the OperatingSystem PlanNineFromBellLabs was released as OpenSource! Both vie for his attention. Plan9 often gets the lion's share.

20090822 several of the links below are BrokenLinks due to some conflicts at my former workplace. Resolution is still not on schedule. Chris is working to resolve both conflicts.

If you haven't looked at ExtremeProgrammingRoadmap yet, you haven't learned why most of us are here. It may have kept me from many of my (more than) tangential pages that are not as extreme.

These are some useful BookMarks for ChrisGarrod - I keep them here because is the shortest URL I can remember.

I once resurrected my wiki from a disastrous deletion by a now retired CowOrker. Most of MyWiki came back online at, but then I was laid off into retirement, and still lack a website that is online all the time.

20070912 My wiki's most recent upgrade is that it now does TabDelimitedTables, simply by treating every line with tabs in it to be part of a table. If a line has the same number of tabs, it's part of the same table. Look at, which is the raw /usr/share/file/magic from MacOsX 10.4.10, I did no massaging at all, it's sprinkled with tables and other stuff that ought to look better with a <pre> but did not need it. Other manufactured tables are at: or or

TabDelimitedTables are the simplest objects understood by both man and machine - Of course, machines understand nothing but sometimes they do the right thing anyway.

You may wonder what the cryptic looking numbers above are. It's a pattern I have been using since the late 1990s, and with it I am y10k compliant! See -- BrokenLink

I prefer this format over ISO 8601:1988 since it has less punctuation, and can be parsed as a single number: 20061005.22070807 especially in a 64 bit environment.

I have designed a new pattern, which is as uniquely recognizable as my DateStamps above: see if you can guess what this is: 32.82541nw117.22279 ??

Not a bad pattern at all. It is a geographic coordinate, so precise that I was able to determine the precise location to be a home of an identifiable married couple. The Internet does not provide much privacy.

My wife probably thinks that it's too precise. Don't tell her. She surfs elsewhere.

Your comments are welcomed and occasionally responded to: WikiMailBox 20070302 I did a bunch of refactoring - or just turning blue of DateAndDarwen -- I haven't read them yet, I'm just getting ready to. Other comments are welcome. My refactoring fingers are tyros.

 8/2/2007 = 0.001993

Let's stop letting computers do the math when that's not what we intend. It is a pattern -- YyyyMmDd.HhMmSs: a point in NonRelativisticTime? -- after all, and that's why many of us came here. Or what the rest of us are learning still...

20101003 ChrisGarrod tried to put this into HelloWorldInManyProgrammingLanguages, but that page kept being reverted by What a deterrent to editing. In my ten years at this wiki, this is the first time my changes have been attacked by a robot. RecentChanges discourages me from participation here. HelloWorld in Scala is discussed in several steps on this page:

 println("Hello, world, from a script!")

Chris, the spoofing is so widespread that most regulars don't use the UserName at all. Thank you for the contribution on CliffordAlgebra. I try very hard to concentrate on making some contribution here and ignore as much as possible of the noise. -- JohnFletcher

Chris, I have put your contribution of HelloWorld for ScalaLanguage back into HelloWorldInManyProgrammingLanguages in the hope that it will stay there this time. I have not signed it - you may care to do so. My interest in ScalaLanguage has been aroused by the new page DeprecatingTheObserverPattern. -- JohnFletcher

Your comments are welcome here, please add them near the bottom. Correct spelling everywhere. Please annotate your comments with your RealNamesPlease and a DateStamp YyyyMmDd, Thanks!

20131117 Who knew that this DateStamp was a PrimeNumber? My mother died this morning. Mourning. Move along, these are not the droids you are looking for...

20140113 Dash means subtract: 2014-01-13 = 2000 Slash means divide: 2014/1/13=154.92 1/13/14=0.0055

20141026 not till today. Looking into it now... Happy Halloween. Dots? First dot represents end of integer, decimal portion continues ... second dot breaks the lexer, ends the number, acts like an end of sentence, and perhaps another integer continues. Your above may lex like: 15.10 and 2014 -- at least you recognized that the 2 was the MostSignificantDigit.

 2014-10-26 = 1978 that was a good year.
 2014/10/26 = 7.75...
 10/26/2014 = 2e-5
