Why is Slush Pool recognizing my worker as offline?

When you mine with less than 1 GH/s (1000 MH/s) most bitcoin mining pools will show your hashrate as zero. This is likely to happen at many pools even with 10 GH/s. This is because the current default/...

When a mining pool pays out to the workers, why does it not just cache the transaction and then pay zero fees on its next successful block?

Sure, you can use your own blocks to send transactions instead of spreading them out on the peer-to-peer network and let anyone include them in their blocks (may require fees). The upside as you say ...

What is the precise nonce finding protocol?

There is no concatenation. The nonce is part of the block header. The block header is 80 bytes and is hashed twice. That means you first sha-256 hash the 80 byte block header, and then you hash the ...

Slush's pool worker offline

At this point 2 TH/s is ok for small miners, 2 GH/s is crazy slow and 2 MH/s is probably not enough for the pool to even detect that you are mining at all. So that's most likely your problem. Even ...
