wpa_supplicant wifi suddenly not working topic

Everything was working before.
Then, I made the dumb error of editing the binary file /sbin/wpa_supplicant with pico text editor.
and now it doesn't load at all and consequently, I don't have wifi support.

I tried downloading and compiling a new wpa_supplicant from their official site, but it seems that my ubuntu doesn't want to care about the replaced wpa_supplicant anymore. Like some bird kill abandoning her eggs after they were touched by men.

Help!

Thanks.

Hard Drive Space Suddenly Full topic

I am pretty new to the Ubuntu world, having most of my computer experience with Macs. But I recently bought a PC to act as a Plex media server and am running the newest version of Ubuntu to save on general system resources.

All was going quite fine until today. I have a 1 TB HDD and ~300 GB worth of movies on the drive. But randomly this afternoon, my system decided to show that I have ~928 GB being used with only a few GB free to use. I ran the disk usage utility and it is showing totally conflicting information. It "confirms" that I am using 928 GB, but the actual folders don't add up to that. The largest folder I have is 306 GB and is nowhere near the 928 GB number. I tried emptying the trash, although that was only a few MB at best. I tried pokling around to see if maybe I duplicated a folder or something in error, but I'm just not seeing where the heck the other 600+ GB is that the system is showing as being used. I attached a screenshot of the disk usage report, if that helps.

I apologize if this is not enough information to go by, but I am not very computer savvy in this regard. Any help would be most appreciated.

[ubuntu] wireless suddenly disabled on reboot...how to troubleshoot? topic

I am a relative newbie, running 14.04 on a Thinkpad X60 (dual boot with XP). I've never had any problems with the wireless connection until rebooting today; the applet shows no networks. In System Settings, everything looks correct... Checked Wifi in XP - works fine (not that I'd go online with XP!) I began researching how to troubleshoot this (rfkill, etc) and was confused by the options.

Any guidance much appreciated...Where do I begin?
