You are not correct, electricity is NOT the most expensive way to generate heat, IF you do it through a heat pump (which generates 3X the heat per dollar of baseboard which is cheaper than all other forms of heat, and a heat pump fed by geothermal, ie ground source is best of all for the majority of the US except the deep south). Resistance based heat on the other hand is often the most expensive source of heat, though if I'm not mistaken oil based heat is pretty close in much of the country (electric baseboard heat is nearly 100% efficient and oil is 80% or less). I'm studying HVAC at the moment though my background is in computer science and I love the geeky side of the field. I am strongly considering converting a huge commercial building and my own home to goethermal (ground sourced heat pump) due to the incredible efficiencies.

I switched from MySQL to PostgreSQL and converted a 50,000 line program to boot. We used schemes to match the way MySQL uses databases (schemes are much closer to MySQL databases than the thing called databases are). Also I use phong admin so I don't use the SQL commands you mentioned. What an inefficient use of time!

I was in the same boat, I have an image processing algorithm that can take up to 10 seconds on an older mid-range CPU, its for the processing of product photos into high quality "perfect" production ready photos. I am also a C# programmer, and when looking into options I came across CUDAfy.net. it lets you code in C# and uses ILSpy to take your compiled C# and turn in into CUDA C which is then compiled. This is then cached so production machines only need to include the cache. I just spent all day today recoding my algorithm and while I found it a little complicated to get started (mostly since I didn't understand how threads and "blocks" work initially, I got my algorithm ported in a day (well the main part, some of the little cleanup, probably another day or two to be 100% ported). I think that's pretty dang good especially since my original algorithm was not even run in parallel. Also I timed it and its taking 0.3 seconds, so that's about a 33X speedup so far, I figure the remaining code will bring that down to about 20X. I'm using a GTX 650 TI Boost card which cost under $200. CUDAfy.net can also work with OpenCL though I haven't tested that aspect out yet. Overall if you want the most painless shift from C# to GPU coding I would recommend checking out CUDAfy.net Its free and licensed under LGPL so you can use it in commercial code.

I have a 37" TV running windows 7, a core 5, 4GB RAM, and a high-end video card, and it plays with my native resolution of 1080P (though the software may actually be displaying 720P, I can't tell the difference). It runs perfectly smoothly, indistinguishable from cable (except its crisper). Maybe you should get an upgrade? This whole rig only cost me $800-$900 6 months ago, it would probably be $600 or so today.

That you should give away all your money.

Give all your money away to feed the poor was in response to one person asking Jesus what HE could do to be more holy. The man couldn't do it and walked away and Jesus said it was easier for a camel to go through an eye of a needle than a rich man go to heaven. That is not what he told his disciples to do nor was it something spoken about by any of the apostles as a command. However we are to care for the poor. (Matthew 21:19)

That you should hate your father and your mother.

Jesus does NOT teach we should hate our father and mother (Matthew 10:35). He actually condemns those who say they can't care for their elderly parent's because they have already promised it to god (Matthew 15:5). He does say he came to set father against son, etc. He is the "stumbling block which the builder's rejected". He causes division in our lives, but we are to live as loving and kind a life as possible, while at the same time being honest.

Pretty much the whole of the gospel message has been thoroughly rejected and rationalized away by the "church".

Gospel means good news. These things weren't the good news. They were part of it, they were in part written to show how hopeless of sinners we are. Jesus says in the sermon on the mount, "be perfect therefore as your father in heaven is perfect". He is presenting our need for a savior, which is who he is. Without him we are without hope. Anyway I'm one of those crazy Christians who has read the bible numerous times and the New Testament 25-30 times. It seems like you've read parts of it, but the things you said were really taken out of context and are not representative of the teachings of the scriptures. Also the Good news, aka Gospel, is that "While we were still sinner's Christ died for us" (Romans 5:8), and that if we "confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved." Next time you want to say what the bible says, why not quote some verses, they are there to make it easier to reference things.

If you fail to plan, plan to fail.
