Utility to zero unused blocks on disk

I unscrew the casing, extract the disk platter(s), slide a very strong magnet over both sides of the platter surface then bend the platter in half. How secure is that ? I can't afford a machine that

Camping and ruby2ruby
Hi everybody, I would like to use ruby2ruby in a caming project, but there seems to be an incompatibility with camping, ruby2ruby and markaby. Unfortunately I receive strange Markaby::InvalidXhtmlErrors. To demonstrate, that only combination of all three components causes the problem I added the following code. I relies on Markaby and ruby2ruby only and works fine (a.k.a. as expected).

Why does 'extend ActiveSupport::Concern' cause `undefined method 'recycle!'`?
Working on Rails Engine. I want to make the controllers customizable whereever the Rails Engine is used.

Compatibility of Hitachi Deskstar 7K3000 HDS723030ALA640 with ZFS
Greetings, Quick question: I am about to acquire some disks for use with ZFS (currently using zfs-fuse v0.7.0). I''m aware of some 4k alignment issues with Western Digital advanced format disks. As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses 512B sectors and so I presume does not suffer from such issues (because it doesn''t lie about the physical layout

Utility to zero unused blocks on disk
DBAN is obsolete. NIST 800-88 for some time now says to use secure erase or enhanced security erase or crypto erase if supported. Other options do not erase data in remapped sectors. Chris Murphy

rsync patch
I've made a small patch to rsync that adds three options that are useful in data-recovery situations. I don't know whether the maintainer will want to add this to the official distribution, but he is free to do so if he wishes. At present, I don't have anywhere to host the patch but I wanted to make it available so it may be tested more thoroughly. To be honest, I haven't

The ZFS Read / Write roundabout
Hey all - Was playing a little with zfs today and noticed that when I was untarring a 2.5gb archive both from and onto the same spindle in my laptop, I noticed that the bytes red and written over time was seesawing between approximately 23MB/s and 0MB/s. It seemed like we read and read and read till we were all full up, then wrote until we were empty, and so the cycle went. Now: as it happens,

Digium TDM400P in Soekris net5501-70?
Hello - I've been running Asterisk (quite happily!) for several years now using a Digium TDM400P card in an old Linux box (P4 1.6 w/ 256MB RAM). I'm also running another old PC running m0n0wall as a firewall. Between these two boxes, that run 24x7, I'm drawing a lot more power than needed and hoping to make a dent in my monthly electric bill by consolidating the two into a single box
