could it be compromised and we get virus?
Is this for only people using the bitminter mining client or anyone using site to check live stats etc.?
If you have Java plugin activated in your browser then a hacker could leave something on a webpage to take control of your computer if you view that webpage. It can happen to anyone using a browser with Java plugin turned on.
It's a bit annoying because Java is how BitMinter client is so easy to start, just clicking on a webpage. If you turn off Java in the browser to protect yourself from hackers then you can't start the miner that way. But as long as Java is still installed it should be possible to start it from commandline with "javaws
http://bitminter.com/client/bitminter.jnlp". So you can protect yourself and still use the client.
Why are rejects so high right now?
I just restarted the mining server, that causes some rejects. Sorry about that, I try to keep it to a minimum.
Update now is faster authentication, which should speed up response a bit especially just after a restart when all users have to get re-authenticated. Also turned off rollntime for cgminer and bfgminer below version 2.7. Please upgrade to the latest version if you use one of those two miners.
Once in a while when those old miners start DDoSing the server some miners experience response times up to 30 seconds. It is worst in the "slow response queue", so those miners are mostly DoSing each other. But hopefully this update will help reduce the problem.
