Some years ago i discovered podcasts as a great way to listen to and learn something while commuting or excersing. I like the different formats like long interviews and the variety of available topics. Here are some podcasts i came across, and that i listen to from time to time:
Instead of having a list of ham radio news sites in the blogroll list, i decided to post them here. This may get updates occasionally when i find another interesting page:
My previous job was maintaining the zfcp device driver in the Linux kernel. Among cleaning up the code, implementing new features and answering support requests, i also gave presentations about using SCSI attachment with the s390 platform. Here are a few links to the publicly available slides and recordings:
- SCSI over FCP for Linux on System z – Introduction and New Features (SHARE 111, San Jose, California, August 2008)
- Additional Feet for the Penguin – SCSI over FCP, Multipathing for Linux on System z (SHARE 111, San Jose, California, August 2008)
- Introduction to SCSI over FCP for Linux on System z (Webcast, October 2010)
The team authoring the Performance Measurement and Tuning Redbook kindly thanked me for contributing. While working in this position, i also co-authored the article IBM zEnterprise storage I/O advancements in the IBM Journal of Research and Development.
Being interested in technology and having played with voice over IP before, i came across the Disruptive Telephony blog. The article “Slides: How The Hidden Secret of TCP/IP Affects Real-time Communications” references the presentation “The hidden secret of TCP/IP and the internet” which raises an important point: TCP/IP and the internet enable communication from anywhere to anywhere. But the reality is that communication is divided in islands, each controlled by a different company. Communication between the islands is almost impossible. Maybe it is time to demand more interoperable solutions. The presentation focuses on telephony, but the same is true for other aspects like social networking.
script is a useful command for quickly capturing a terminal session, as i just learned here:
$ script test.log Script started, file is test.log $ mkdir x $ ls x/ $ exit exit Script done, file is test.log $ cat test.log Script started on Wed 03 Aug 2011 02:33:36 PM MST $ mkdir x $ ls x/ $ exit exit Script done on Wed 03 Aug 2011 02:33:41 PM MST
