The HondaJet

March 4, 2010 Rand Simberg 8 Comments

A review, by Glenn Reynolds, over at Popular Mechanics. A commenter claims that the engine development is having certification problems, but I don’t know how credible the commenter is.

I found this interesting:

Honda is also saving development money by taking advantage of modern computer power. Fujino notes that it’s possible to do serious design work on a laptop nowadays, where not long ago it took an expensive engineering workstation. And Honda is making heavy use of simulations, with a sophisticated whole-aircraft simulator that allows real parts to be swapped in and tested against virtual parts and vice versa, allowing many stages of refinement before parts ever reach the test-flight stage.

I wonder why these kinds of development-technology savings aren’t making their way into the spacecraft design world. But they probably are, actually. It’s one of the reasons that SpaceX has accomplished so much for comparatively little money. And when you’re on a cost-plus contract, you can always find other ways to spend the money.

Graphics Card Question

February 28, 2010 Rand Simberg 11 Comments

So my Samsung LCD monitor gave up the ghost (less than a couple years old, I think), and I went out to Frys to get a new replacement. I was looking at the displays and some of them looked like crap (blurry letters). I asked the salesman, and he said that they were being fed with VGA analog, whereas the sharp ones were digital (DVI or HDMI). If I were the manufacturers of those monitors, I’d be pretty unhappy with that situation, but I digress.

Anyway, I determined to not only get a replacement monitor, but to upgrade my video card as well to digital output. So I bought a new LG 21.5″ screen, and an MSI card with an NVidia N220GT engine, and a gig of DDR2 memory.

I got home, put in the card, and it turned out not to work without having to update Linux drivers from NVidia. But in changing it out, I also noticed that the old card (also an NVidia, with 128M of memory) had a DVI output, so I didn’t really need the new one in terms of digital output support. So I’m running with it now.

Question: I’m not a gamer, and don’t do anything really graphics intensive, such as video processing. Is there any point in updating drivers and reinstalling it, or should I just take it back and get my sixty bucks back? Will I see any performance improvement from it?

[Monday morning update]

Thanks for all the input in comments. I don’t need any of the things that y’all say the card will help with, so I’ll be taking it back. If I ever do need it, I’ll get a better one, cheaper, at that time.
