  • I have an attic that gets direct sun until the afternoon. It gets quite hot. I had easy access to the rafters so I used radiant barrier, and the difference is very big. As you’re putting it up you can tell that it’s blocking the heat standing in an a covered vs uncovered area. In subsequent days when it was all up it was obviously cooler. It’s still hot but not unbearable.

    Radiant barrier is more expensive and fiberglass probably would have worked just as well in this situation, but I didn’t know enough about air flow in that space to tell whether fiberglass would impede anything,so I used radiant barrier and left a gap at the bottoms and tops. It is very easy to install. Fiberglass wouldn’t be too hard either, but the barrier is daed simple and there’s less volume to move around.

    In general, my experience say it’s going to help, and whether you do fiberglass or radiant barrier is up to you.



  • I hear a lot that gas is cheaper for heating and I took that as the truth for a long time. A while ago I did the math though, and for my house is would have been nearly the same annual power bill if I replaced my 90% gas furnace and water heater with electric units. Although the price of gas is far more economical for heating, there’s a monthly gas usage fee that’s a flat rate. If you go all electric, you don’t pay that, and over the course of a year, I didn’t heat enough for the lower gas price to offset the flat fees. If instead of a regular electric furnace and water heater, they were heat pumps, electric would have been much cheaper than gas.

    This certainly would depend on your local prices and weather and how well your house is insulated, but if you need a new furnace, I’d do the math over a year to see if gas is still the most financially attractive option, especially if you can install an air or ground source heat pump.











  • This is one of two “warts” that I know of in SI. They wanted a coherent set of units, coherent meaning that no nuisance constants are required to convert between dimensions in the set. The system at the time was gram-centimeter-second. To expand things to all dimensions I suppose it was simpler to use the larger units, like J = kg m^2 / s^2 rather than trying to make a new unit for energy, etc. You’d think they’d have just come up with a new name for mass units and defined it as 1 kg, something like 1 prot = 1 kg, then all of the coherent units would be ones without prefixes. Someone must have really being going to bat for the word “gram” though, because now we have this pretty stupid rule that the coherent units are all of the ones without prefixes, except mass, which has the coherent unit of kg. And then also, prefixes are used to scale the coherent units by appending the appropriate letter to the coherent unit symbol, except for mass, for which g is treated as the coherent unit, even though it’s not.

    It’s not the worst thing, but it’s pretty stupid to explain.





  • I have used both Windows and Linux extensively, and although Linux used to be a serious amount of nonsense to get stuff to work, it’s not like that any more. I spend similar amounts of time troubleshooting on each. Help for Linux sometimes is better. If you end up on the Microsoft answers forum, good luck to you, because it means the real answer is buried somewhere on the Internet, if it’s there at all.



  • Does the interface that you have now work under Linux? Linux has pretty good support for a lot of things now, so you may be able to use what you have. Reaper also has a generous free trial, so potentially this is a free experiment. (I’m no expert and just tinker with this stuff, but I have Reaper and I find it similarly easy/difficult as every other DAW I’ve used) Several distributions have “live images” where you can run it from a flash drive without copying anything to the hard drive. I don’t know if you could set up Reaper and your interface from a live image.

    If you do decide to do an installation, consider buying a different hard drive and installing Linux on that. You can install both Windows and Linux on the same drive, and it’s not difficult, but it is slightly easier to use a separate drive and they are not expensive.

    I have used Linux and Windows a lot, but I have only used Reaper in Windows, so unfortunately I can’t say whether it’s a similar experience.
