Comment Re:why dont they spin it? and land it in a silo? (Score 1) 342

The spinning would have to be slow enough that you could either gimbal the nozzle or modulate the thrust at the same frequency as the spinning. I don't know which of the two controls is faster. I don't know about the economics of this. It's probably not economical.

Comment why dont they spin it? and land it in a silo? (Score 2) 342

A bit of rotation should help to keep the thing upright. The gases being pushed into the silo will be forced towards the walls on their way back out and help center the rocket as it enters the silo. A funnel-shaped silo is easy to hit and provides a soft cushion as the pressure of the backscattered gas increases as the rocket descends into it. Finally, a rotating platform at the bottom needs to be synchronized to the rocket's own rotation. Good Thing I don't have the billions it would take to see my brilliant ideas crash and burn.

Comment Re:Are there open source tools... (Score 1) 64

I have no such illusions. But I would expect open source tools to at least function equally across FPGA brands, at least to the extent that people are able to reverse engineer the bitstream formats of the various architectures. The quality of software in general correlates strongly with the amount of manpower that is put into it, which again correlates strongly with funding. On that note, I think the case could be made that some FPGA producers would benefit from an open source and cross-platform toolstack, particularly those that are not currently market leaders.

There are several open source vhdl / verilog projects, including tools for simulation and synthesis, mapping, placing and routing. Examples: HANA, yosys, Icarus. But I guess you usually get better results with the free-as-in-beer tools from the fpga manufacturers. Which is a shame, since it would be nice to have some open source tools. Although everyone use the same hardware definition languages, it is a pain in the neck to switch between FPGA brands, mostly because the build tools are different and all pretty quirky.

Comment Bury a tree (Score 1) 363

Planting trees is fine, but hardly the best use of your time since trees tend to pop up on their own just fine. If you want to sequester carbon, your time is probably better spent preventing the carbon which has already been bound in existing trees from being released into the atmosphere. For instance by burying a tree in an anaerobic swamp. Less romantic, more effective.

Comment Why are coders contributing? (Score 2) 488

Because it's fun? An opportunity to develop skills? Peer recognition? Because you need the software/bugfix/feature yourself and can't or won't make money out of it for some reason anyway so there's nothing to lose? Need a reference to further your career? These are the kinds of reasons I believe in. Do these apply to non-coders?
