Tried to unzip but couldn't.

[kathryn@Galaxy ~]$ cd rrbeta/
[kathryn@Galaxy rrbeta]$ unzip readyreckonerv8beta1.zip
Archive: readyreckonerv8beta1.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of readyreckonerv8beta1.zip or
readyreckonerv8beta1.zip.zip, and cannot find readyreckonerv8beta1.zip.ZIP, period.

Fedora 7, FWIW.

Email me if there's something else you want me to try.


Wow that was quick, thanks Kath!

I think I've fixed it, try the same link again please ... :-)

Cheers, Mike.

It should:[pre]
- resize pleasantly
- exit using the menubar : File -> Exit
- minimise/restore/maximise/exit with the usual upper right icons
- give a prissy 'About' box using the menubar : Help -> About
- select between 'Data'/'Validate'/'Plotting' panes using their tabs
- on the 'Data' tab I expect:
- 'Clear' button to clear the central yellow text area.
- 'Load' button provokes a file open dialog
- 'Save' button provokes a file save dialog
- 'Validate' button moves you to the 'Validate' tab
[/pre]


All the above tested, and work as described. And the zip unzips with WinZip.

32-bit Windows Vista, with Sun Java Version 6 Update 5.

And I can't find .rrd in any of the online reference lists - I think you're safe there.

Keep up the good work!

Unpacks fine now.

Runs fine using `java -jar ReadyReckonerV8Beta1.jar`

And it does everything you expect it to do at this point.

Nice job!

It also starts up by just double-clicking the .jar file in Windows Explorer, at least with my Java install.

Same here...

I have a new frequency template to work on after I get done with the LHC tasks I have, so I'll try to play around with it then...

RE: DELETE column_name FROM

DELETE column_name FROM table_name WHERE column_name = value;

At least in the Oracle syntax it is part of the ALTER TABLE command with the rest of it.

So I took the liberty of checking on DELETE functionality. In every major database, DELETE can only handle deleting an entire row, not just a specific columns (tuple, field, whatever) value. In a moment of "not wishing to be a total jerk", I decided it wasn't worth having a confrontation with them...and so I kept that nugget to myself. As I told my Mom, I learned something, even if they did not...


The "beauty" of SQL is that there are only 3 data manipulation statements ...

The ugly thing about SQL is that there are only 3 data manipulation statements ...

Though I have one that when formatted fills 2 11x14 sheets that used to work against the Designer 2000 database design tool to extract data for one of my custom reports ... though large with many nested and "linked" statements it was still blindingly fast ...

The trick in SQL is to think in terms of the resulting data that you want in terms of sets of information ...

Bump ... I haven't

Bump ...

I haven't forgotten you all. :-)

This weekend I should be able to give a second beta version with much more functionality [ Data input right through to curve fitting and graphics ].

Now as I'm always thinking of future expansion : I'm going to leave a couple of stubs ( to be filled in later ) in the code for:

(a) Programmatic HTTP interrogation of one's account - essentially automating the retrieval of the data lines ( CSV ) we have been dealing with. The potential downside is hammering of E@H servers if done indiscriminantly. Any thoughts?

(b) following from (a) - introduce another type of data file which stores the important user and host information/properties between sessions. Simple things like user names or host characteristics so that the GUI can present identifying information with more than just the numeric identifiers used currently. As you will see, the validated data will be presented in a tree form with ( ultimately ) some editing capability. It would be nicer to have it more at-a-glance human readable.

(c) Direct printing support is problematic across platforms using pure Java, as printer and capability discovery are not mature enough to be relied upon. But I can emit HTML pages/files ( with embedded custom graphics - gif's ) from Java code and automatically invoke a chosen browser if desired. The user can then save the file, print it or whatever to please using one's installed browser. Probably a better route.

Essentially I've discovered that the terrific central theme of Java - Write Once Run Anywhere ( WORA ) - is quite often honoured in the breach. [ I'm standing firm on the cross platform requirement ]

Cheers, Mike.

Gosh it's quiet around here

Gosh it's quiet around here isn't it? Let's see if I can't start some sort of feeding frenzy then ... :-)

Now RR8 Beta 2 is available. Note it has a 'readmefirst.txt' file.

It doesn't yet exceed the RR7 functionality, but please have a bash at it, and tell me how it goes :-)

Enjoy!

Cheers, Mike.

( edit ) Since Brian ( & others ) may be curious then here is the source code - but only loosely documented. It's the relevant Netbeans project/workspace. I've gotten over my code-shyness .... :-)

This is printed in the console window. Sorry I had to pastebin it because it really messed up the forums here.

Bottom of the window is cut off. (fairly large image warning)
