[edit] My other identity
My real name is Madhu Siddalingaiah, in case you were wondering.
If you want to contact me directly:
Yes, that's supposed to be an @ in the middle. The image will hopefully confuse address scrapers. If you know of a way to add @ to math image, let me know!
[edit] This Wiki thing just might take off!
A fantastic concept, the content is equally impressive! The Web is really starting to become useful again ;-)
[edit] Background
Science and technology, as you might expect. I have worked in a range of industries such as aerospace, radio frequency communications, digital signal processing, 3D graphics, embedded systems, and of course, enterprise software. I'm a physicist by education, an electrical engineer by vocation, and software engineer by necessity.
These days I do more software consulting and architecture, but I have a fair amount of test equipment to satisfy my hardware interests. Thanks to eBay! Here is a short list of equipment I own:
- Tektronix 2465A, 475A, and 465M oscilloscopes
- Hewlett-Packard 8590A spectrum analyzer
- Hewlett-Packard 8660C synthesized signal generator
- Wavetek 2500 synthesized signal generator
- Power supplies, meters, and other sundry equipment
[edit] Interests
I'm a rated helicopter pilot. I have been flying since 1987. That should explain many of my helicopter related contributions. I have flown Robinson R22, Bell Jetranger, and Hughes 500.
I like to work on embedded systems, wearable computers, wireless controls/monitors, and anything else small and electronic. The simpler, the better. I really enjoy analog electronic design, much more so that digital. Digital stuff can be fun, but it's not always as challenging.
[edit] Facts and figures
- Water is 800 times more dense than air.
- Steel saturates at about 20 Amp-turns/inch
[edit] User articles
I recently saw a video clip of a particularly spectacular helicopter crash. Fortunately, no one was hurt.
Is Pegasus stronger than the average horse? This analysis begs the question.
The sinking of the RMS_Titanic was tragic and largely preventable. Many arguments have been made about what should have been done prior to collision with the iceberg. Some ideas are presented here about what could have been done after collision.
I recently took fantastic trip aboard a vintage diesel-electric train in Minneapolis. The conductor gave us a hands on tour of the locomotive, but first he had to start it...
Some have an idealized, romantic view of the past -- I don't. Older, simpler times, the age of chivalry all suffer from a major problem: bad plumbing.
I've given quite a bit of thought to deterministic vs. non-deterministic processes. Some thoughts are given here.
Is the hybrid alien from Alien: Resurrection structurally weak? Consider this evidence.

- Nothing can be so amusingly arrogant as a young man who has just discovered an old idea and thinks it is his own.
- I look for durable competitive advantage and that is hard to find.
- Nothing in the world will take the place of persistence. Talent will not; nothing is more common than the unsuccessful person with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent.
- There is no abstract art. You must always start with something. Afterward you can remove all traces of reality.
