Rocketry Video utilizing a Strap-on Camera Mount

Amateur rocketry is great fun! 5-4-3-2-1 Launch! The motor ignites, the rocket accelerates upward toward the sky and it's soon well out of sight hundreds, if not thousands, of feet into the air. For a great many rocketry enthusiasts, this would be enough; however, I soon found myself pining to see what I could not — the view from the rocket's point of view. I found numerous on-board rocketry videos on YouTube made by other amateur rocketeers which prompted me to want to try my hand at doing the same. If you too should have an interest in video documentation of your own amateur rocket's flights, read on. (read all 1223 words.)

ssh-ecurity — Part 10: Android Paranoid

The summer season is here again! The pool is open and the dinner comestibles are a welcome anything I prepare on the grill. This year, to replace aging outdoor speakers, I purchased a Bluetooth sound system for my backyard oasis. The plan was to broadcast to it from iTunes on my MacBook Pro or the IMac in the bedroom, but the distance to either yielded undesired sound quality. So, it was either lug out the MacBook Pro — which I was reluctant to do after a recent costly repair to it due to a spilt coffee — and risk getting it splashed from the pool shenanigans, or invest in something else that I could use for streaming internet radio to the Bluetooth sound system. I finally opted for an Android tablet. A couple of downloaded apps and I was streaming Aural Moon to the Bluetooth system. Now, armed with a new toy, my inner geek was pining for other things that I could do with this tablet. The first thing that came to mind was configuring terminal access into my OpenVMS, Mac and Linux systems; securely, of course! (read all 1177 words.)

MOVPSL — I've a feeling we're not in Kansas anymore!

Having just completed the latest round of new features for the TMESIS DCL Debugger, it was time to build and test the code on all three OpenVMS Architectures — VAX, Alpha and Itanium. The development of the project had been seeded on the Alpha; thus, that's where it has remained to this day. When a new feature or bug fix has been vetted on the Alpha, the code is then built and checked on OpenVMS VAX and OpenVMS Itanium. Everything newly added was working fine on all three platforms, so it was time to run through some of the regression tests. What this uncovered surprized me. The EDIT functions, which had nothing to do with the newly added functionality, were failing on the Itanium. Never underestimate the need to perform regression testing! (read all 2234 words.)

ssh-ecurity — Part 9: Confusion will be my Epitaph!

I have received myriad accolades for my series of blogs on ssh; especially, because it has covered the inter-operability issues with OpenVMS, Linux and Mac OS X. Despite the series, I am still being called upon to assist with ssh implementation on all three of the aforementioned environments. It is, of course, not a bad thing for one, like myself, who is in the computer consulting business but, in almost all of the cases, it was because of simple and stupid errors introduced when taking my blog examples and massaging them into one's own working environment.
