<td><!-- hotel -->★★ A strange but interesting place. needed increaed water pressure if you want a hot shower.</td>
<td>With the forensics puzzles, having the same for the classroom vs the contest helped those that took close notes. There is way too much use of Encase and limits on how far yoyu can get if you are unfamiliar with it. </td></tr>

<td><!-- instructor -->★★ The portions of the instruction that were lecture only could have been improved by having students follow along and actually participate. For example, instead of teaching Windows Registry purely by lecture, have students open Regex or examine the Registry using EnCase.</td>
<td><!-- classroom -->★★★ Good facilities and connections. No complaints.</td>
<td><!-- class-content -->★★★ Aside from the pure lecture portions, the content was good. Exactly what I expected when signing up for a forensics course. Good that not a lot of time was devoted to teaching the basics of the programs, like EnCase.</td>

<td><!-- contest-ambiance -->★★ Would it kill you to play a little Smokey Robinson? ;)</td>
<td><!-- contest-network -->★★★ No complaints.</td>
<td><!-- contest-lanl -->★★★ Awesome puzzles and contests. So much to keep everyone busy. Maybe a little too much material for smaller teams to even make a dent in scoring points. My only complaint is the way in which answers are required to be formatted. See the General Comments section for more detail.</td>
<td><!-- contest-sandia -->★★ I didn't really participate much in the Sandia Jeopardy business. From what I saw, it looked good.</td>
<td><!-- contest-vendors -->★★★ Good way to show off their products without it being just a sales pitch. The puzzles they provided were great.</td>
<td><!-- hotel -->★★★ Nice. No complaints.</td>
<td>Participants should not have to decipher the format of the answer for the questions on their own. Dates/times entries either need to be in a precise, specified format or the system should be able to taken input and determine whether or not the correct answer is known. Whether or not an answer is correct should be determined by upper or lower case letters. The scoring systems should be able to compare the data submitted and normalize the input and compare it to the correct answer.</td></tr>

This lacking was my background knowledge.
Next time I am going to be a lot more prepared for the challenges.
This was my first ever Capture the flag and participation in a exercise like this but you certainly have found a permanent participant.
A+++++ will do it again.
Tracerfire starts from where all the text books ends.

How to run a CTF event
======================
When a CTF image boots, it goes through the following sequence:
When DBTL boots, it goes through the following sequence:
1. Mount a partition labelled "CTF-STATE" read-only under /var/lib/ctf,
if such a partition exists
2. Mount a partition labelled "CTF" under /mnt/ctf
3. For every file matching /mnt/ctf/${pkg}.pkg, mount it under /opt/$pkg
4. For every directory matching /opt/*/service/${d}, copy it recursively
into /var/service/$d
1. Mount a partition labelled "PACKAGES" read-only under /mnt/packages
2. Mount a partition labelled "STATE" read-write under /state,
or make it a tmpfs if no such partition exists
3. For every file matching /mnt/packages/${pkg}.pkg, mount it under /packages/$pkg
4. For every directory matching /packages/*/service/${d}, copy it recursively
into /service/$d
