Really tiny executable

Thought this was neat:

The author uses assembly and ELF-hacking to make a binary as small as possible while still doing something useful (returning a value). Goes step-by-step through each hack.

Holy Binary Blobs, Batman!

Posted 01-25-2012 at 02:58 PM by hydraMax (Bits and Pixels)

Just how many binary blobs are there in the kernel...!? I finally enabled "deblob" for my gentoo kernel sources, and it took the build five minutes to remove all the kernel blobs! Must have been hundreds of them. I think I saw my Ethernet driver scroll by... hopefully I have networking in my next boot. (*gulp*)

New Printer: Brother HL-2270DW

Posted 01-25-2012 at 03:39 AM by hydraMax (Bits and Pixels)

It's everything I wanted: an inexpensive, Ethernet capable, Linux-compatible laser printer (I hate inkjet).

I have beta source code available for another small utility I coded, called Archive Diff. It is a convenient tool intended to let you quickly see the differences between the files in two archives, without going to the trouble of unwrapping the archives yourself or running the proper diff commands. The target users are those who like to install software from source code but also like to know exactly what source code has been changed between the two versions (i.e., without trusting the ChangeLog or...

Security issues in opening an archive

Posted 01-17-2012 at 10:21 PM by hydraMax (Bits and Pixels)
Updated 01-17-2012 at 10:23 PM by hydraMax (typo)

I've personally opened hundreds (thousands?) of compressed archives -- tar, zip, and otherwise -- without even thinking of the possibility security ramifications of this action. However, extracting files (insecurely) from any archive has potentially two very dangerous effects:

1. overwriting a file that should not be overwritten
2. placing a file in a location you did not expect

These of course are most deadly in combination. The bsdtar manual page has a helpful...
