Comment I like FreeMind (Score 4, Insightful) 97

I like FreeMind (mentioned in the DrDobbs article). Of course I knew about mind maps before, but the ability to export a perfectly formated map as Pdf, HTML and in various image formats is great. I think I'll be using this instead of paper in the future. I've tried various UML design tools in the past, but they all require that you have already made some of the decisions beforehand.

I think UML is a great way of describing a system once you have made all major decisions, but whenever I need to think about a new project, I have always prefered pen and paper. I'll seriously give FreeMind a go now.

Comment Re:But GOTO is a NONO (Score 1) 307

I see no problem with function/method-local GOTOs. The two main problems I see with the GOTOs of christmas past are:

1. Jumping to a label which is just a number / has no meaning to the developer. GOTO niceNameDescribingWhatIsDoneByCodeFollowingTheLabel removes this problem.
2. Non-local jumping preserves the callers stackframe, but when actually writing the callee code, some of your "locals" are defined in the caller.

Submission + - 3D solar towers offer up to 20 times more power output than flat solar panels ( 1

cylonlover writes: While we’ve seen the development of solar cell technologies that employ nanoscale 3D structures to trap light and increase the amount of solar energy absorbed, MIT researchers have now used 3D on the macro scale to achieve power output that is up to 20 times greater than traditional fixed flat solar panels with the same base area. The approach developed by the researchers involves extending the solar cells upwards in a three-dimensional tower or cube configuration to enable them to better capture the sun's rays when it is lower on the horizon.

Parent was just giving you an example.He was asking you to open your mind to other solutions. Of course you could also save energy and since you guys are all buring oil/gas to warm your houses, how about this observation of a small town in the UK:

When I was looking to rent a house in Cheshire a few years ago, a lot of the ads mentioned "double glazed windows" as a selling point. Imagine that! A house with a bit of thermal insulation, in a country where the temperature will often drop to 0 C / 32 F during mid-winter?

Also, every house we looked at had a gap of at least one centimeter under the entrance door, where cold air could enter, and they all had (funny but true) a form of stretched out pillow to put there, in order to reduce the drag. When I first got there I had to buy a fridge since it was not considered a "fixed appliance", but until I got that sorted, I actually stored my butter and milk in the hallway since it was so cold.
