RE: [aus-dotnet] UML 2 and Microsoft

[Mitch Denny]

Hi IL,

I don't think they are really anti-UML, but I think that they know that many
people (myself included) feel that UML can describe the world - but can't
effectively communicate.

Remember that we use diagrams to describe things which are hard to do in
words, or simply because our audience is a visual thinker. If UML can't
reach an audience because it introduces too much noise then you need to use
another diagramming format. I guess Microsoft believes their format works
better for their developer audience, and I am inclined to agree.

Perhaps also a little bit off-topic, but I haven't been across any
argy-bargy about why (if it's true at all) Microsoft is "against" UML and in
particular UML 2.0  - this ComputerWorld / InfoWorld interview points the
finger (at least, the IBM guy does) - 

 

InfoWorld Editor at Large Paul Krill talked about the subject with Brian
Selic, IBM Distinguished Engineer and co-chairman of the OMG task force on
UML 2.0.

Can anyone educate me on this?

I was able to save the page to disk fine, but if you're having problems with
that particular page, click on the Printer Friendly button on the left and
save that version - less than half the size (and most of that would be
unneeded Javascript).

Curiosity about 1752 and the change to the Gregorian calendar led me to link
to the page 

http://www.ancestry.com/learn/library/article.aspx?article=3358 

and I decided to save it to disk - but IE6 won't play

 

I've asked this on MS newsgroups (I hope not here; if so, sorry folks) and
don't get a wholly convincing answer. The work-around I use when I really
want" a page is to print as a PDF file. But that's not always great, because
some webpages are made for screens at 1400px width and can't print to paper
(hence, a PDF default A4 pagesize slices off the right margin).

 

Any thoughts?

   Your info is correct for England.  In Russia, IIRC, the days were removed
in 1917.

	By the way, do people know why SQL Server uses 1753?

	 

	About 8 years ago I was doing some SCO System admin, when I stumbled
across some interesting information reading through the "MAN" command
(online manual) pages, looking for information about date-related commands.
It's interesting to note that in September 1752, 11 days were subtracted
from that month in Gregorian calendar (the one used by western society
today). Interestingly SCO Unix displayed a calendar for that month - with
exactly 11 days missing.

	 

	Curious about the details of the calendar change, do a search for
words "gregorian","1752" and "semptember". eg...

	http://www.ancestry.com/learn/library/article.aspx?article=3358

	 

	.Net uses the same method as SQL for controls DateTimePicker and
MonthCalendar - you cant display it because of a curious mindate. Not much
of a problem for most applications.

	 

	Tim.

		A date always has a value.

		Date dt = new Date() = 00:00:00.0000000, January 1, 0001

		Your problem is that this is probably less than the allowed
value for your datatype.

		eg SQL Server datetime type has a min value of  January 1,
1753 .

		 

		Usually it's best to insert a null for unassigned dates.

		ie. if ( dt > DateTime.MinValue)

		        set param here...
