do you update the miners to the latest version?
also i do not see the algo for skein. is it possible to add it?
I will update miners when I can, but can't keep up with everyone. If you have a specific miner you think has important performance or stability improvements let me know and I can update.
Skein is not usually one of the most profitable algorithms and so I haven't hooked it up yet.
is it opensource?
Not open source as of now, since I feel like someone else would just come in and take my work. I have a motivation to keep my miner clean and reliable to increase adoption and make income from the small fee. You are free to wireshark it and run it with process monitor to make sure it is a friendly app if you don't trust it. All I can offer is my word that I would never do anything malicious.
