sed saves the day

The following command:

        sed -e 1,250000d report.tsv > output.txt

Removes the first 1/4 million rows from the given file before passing the output to a file.

This is very useful when a tsv file is 15 Mb – way too big for excel to view.
sed may be old, but it does do the job quickly that very few other tools handle so well.

Web Services and Mono

~ chriseyre2000 ~ Leave a comment
I have been experimenting with MonoDevelop on a Breezy Badger Ubuntu system. Until now I had limited myself to creating Hello World style console applications.

I have just got a Hello World web service client to run under MonoDevelop. The only sticking point that I had found was forgetting to add System.Web,Services as a reference.

Given that the mono wsdl works that well we have a great opertunity for interoperability. The promise of web services can be realised.

Web Services and Web References (part 2)

~ chriseyre2000 ~ Leave a comment
I have just finished a web services training course.
Apparently setting a web reference uses wsdl.exe in the background so the two are equivalent for creating a proxy. However wsdl.exe does provide far more control.

The problem comes with the update web reference option. If you have decorated the proxy with attributes (such as a soap extension) these are lost upon regeneration. There does not seem to be a clean way of managing this. We really need more control of the template than WSDL.exe provides. I am sure that xslt could be used…

.NET 2.0 does promise more control over this generation.
