I don’t know why zip can’t handle multiple inputs, but it cant’. Gzip does just fine unzipping everything in a directory, I use this little “script” all the time on the command line to unzip all the files in a directory.
for file in $(ls *.zip) do echo $file unzip -o $file done
Its a small simple script, but it’s useful.

I just got two additional block erupted blades today, they have been over clocked from 10GH/s to 13GH/s. By todays mining standards this isn’t much hashing power, but I got them very cheap. I had the backplane for these things, but have been having a hard time getting it to not overload the power supply I was using. I started to look online at what type of power supply you could put directly into the backplane, and it was a HP DL380. Ironicaly I just bought a HP DL380 G5 to be my new web server. In fact in a month or so, this website will be hosted on that server.
Since these are redundant power supplies, I just pulled one from the running server, and slapped it into the backplane, and I just upped my hashing power by ~26GH/s

I have a stupid problem, I have a Bitcoin ASIC called a Hex miner. For some reason every 12 hours the thing slows down from 24GH/sec to 5GH/sec. The only way I have found to solve the problem is to power cycle the controller and the unit itself. This would be a pain since I have it in my basement. However I salvaged some old Bay Technologies PDUs in my rack, which means I can power outlets on and off through a telnet session.
I did a little searching and learned how to do some scripting with the unix program “expect”
This is a very specific script, but it did what I need it to do:
#!/usr/bin/expect spawn telnet xxx.xxx.xxx.xxx 23 expect "Enter Selection>" send 1\r expect "RPC-3>" send "off 1\r" expect "Turn OFF HEX-WRT? (Y/N)>" send Y\r expect "RPC-3>" send "off 2\r" expect "Turn OFF HEX-PWR? (Y/N)>" send "Y\r" expect "RPC-3>" send "on 2\r" expect "Turn ON HEX-PWR? (Y/N)>" send "Y\r" expect "RPC-3>" send "on 1\r" expect "Turn ON HEX-WRT? (Y/N)>" send "Y\r" expect "RPC-3>" send "menu\r" expect "Enter Selection>" send "6\r"
It blazes through resetting the outlets.

If you haven’t noticed I like crypto currencies, I I was trying to get one of my computers to mine X11 coins on the CPU, just to play around with it, but could not get the client to install. I finally found this article:
https://github.com/ig0tik3d/darkcoin-cpuminer-1.2c/issues/3
I commented out two lines, and everything started working
