Delphi Pipe – Delphi related RSS feed running on Yahoo Pipes – via twm’s blog

Posted by jpluimers on 2015/03/28

New Delphi related RSS feed: Delphi Pipe “A collection of Delphi related RSS streams” which works perfectly fine in Feedly.

You can get the source through

The source is sooo simple, that I now definitely need to make some time to really do some Yahoo Pipes research:

Since Delphi Feeds doesn’t list my blog any more and generally isn’t very fast in responding to requests for adding or removing feeds, I have created my own aggregated feed: Delphi Pipe. It’s done with Yahoo Pipes and currently contains the following feeds (most important first ;-) ):

Oh and thanks Thomas Mueller for listing my feed second (;

Bug him on G+ to get added.

Later he showed how easy it is to convert your G+ stream to an RSS feed: Using Google+ as input for Yahoo Pipes.

Then how to read a CSV file (which is hosted on his site) as input to the RSS generation.

.NET threading: native and managed thread IDs do not per se correlate

Posted by jpluimers on 2015/03/26

Next time I run into .NET and native threading issues:

Main UI threads often have a correlation between managed and native thread IDs.

But for other threads, you cannot be really sure.

Some background articles on this:

Quite weird. About 80% of the repos on github have no license…

Posted by jpluimers on 2015/03/25

Reminder to Self (this?) put a LICENSE .txt or file in all my repos.

It isn’t difficult to choose one:

For new repositories, GitHub even has a license picker.

Thanks Jan Wildeboer for reminding me.


PS: most of the things I put on-line are using a BSD 3-clause “New” or “Revised” License. But I might go for a simpler one. It doesn’t hurt looking at your licenses every now and then.
