Darth Vader toaster shenanigans

If there's something every Sith Lord knows how to do it's make a balanced breakfast! While the Jedi have to live off of Jawa juice and fried nerfsteak, the Dark Lord of the Sith prefers to have a reminder of his fiery Mustafar defeat at his breakfast table.

From the Star Wars store, a full-blown toaster which burns a Darth Vader logo.

A few reasons to avoid socializing at work


... or why you should avoid messing with your co-workers and stick to your old school friends. While some people prefer to go all way liberal and social, chit chat loving hipsters et al, some find out that work is really meant to be for work and skip the social crap.

Here we go with a few reasons for avoiding (in general) socializing at work:

  1. Your coworkers are far more likely to develop envy and other vicious feelings towards your persona.
  2. Your coworkers are there for the paycheck, probably as much as you are, if not more.
    1. They will most likely do whatever comes around for getting a better one.
    2. That means selling your ass out. Really.
  3. It's human nature when it comes to money to fuck up things. Especially confidence.
    1. Everyone has a price.
    2. Sadly, the world is full of cheap people.
  4. They will usually engage in so-called 'social chat':
  • Buddy X: Hey dude, I'm just back from the gym!
  • Buddy Y: Yo, I bench press 140 pounds, lol!
Let's go on the analysis of the conversation above:
  1. Buddy X is ingenuous e¡to enough to talk about gym. You know, it's about 2% of the world population that truly care about their fitness and shape. People out there think bioimpedance machines tell the truth (you seriously think you have 12% bodyfat if you can't even see the joint point between your chest and abs!?).
  2. Buddy Y knows what anyone who was watched a cheap sitcom knows: there's a thing called bench press. Pushing it further, you get him to know about the Guido work out! (Evil grin).
  3. Buddy X afterwards thinks Buddy Y is a moron. If you weight 200 pounds and you think lifting 140 is quite an accomplishment, you seriously need therapy. Now, if you weight 140 and lift 200, it's not yet an accomplishment but you are more likely to achieve one. Hah.
  4. Buddy Y claims he goes to the gym 'on regular basis'. Buddy X suddenly has to live together with Buddy Y and finds out that Mr. 200 pounds is a bedroom worm. Wake yourself up, soldier! Hah.
Let's continue with more reasons and suggestions...
  1. Never cook at work. Especially in IT jobs, that's like a serious curse on your persona. You are supposed to grow the mandatory belly. That gives you a coolness factor of seventy-five chin-up coupons. Or fast food discounts, whatever comes first.
  2. Your co-workers will hate you if you are able to fit more than just work in your life.
    1. Example 1: Look at Buddy X, he's leaving at 4pm! - a 9pm-regular whispers...
  3. Your co-workers might be a bunch of liberal asses like most commie imitators around the globe. This is fairly usual at Europe nowadays. Now, they wear Levis too.
The solution is simple: quit and kick their butts afterwards. For real and great justice. Army way.

A simple trick to improve Firefox security

Firefox can run with add-ons disabled and what not, but if you run Firefox under Gentoo Linux, using the hardened profile, you can use a simple trick to have two different instances of Firefox available, with different enforcement of memory permissions and the usual PaX features:

PaX features disabled via PT_PAX_FLAGS, will allow most plugins to run without issues (although, for example acroread will require specific permissions on its own binary to run):

paxctl -pemrxs /usr/lib/mozilla-firefox/firefox-bin

Recommended settings (that might slow down Firefox in some systems, with noticeable overhead when there's a heavy use of Javascript or AJAX functionality):

paxctl -PEmRXs /usr/lib/mozilla-firefox/firefox-bin

For Acrobat Reader (only Address Space Layout Randomization -ASLR- can be enabled without affecting the functionality, blame the poorly compiled binary):

paxctl -pemRXs /opt/Acrobat7/Reader/intellinux/bin/acroread

You should try to use a different PDF application anyway, if you really trust any of them :)

Description of the PT_PAX_FLAGS flags:


PaX control v0.4
Copyright 2004,2005,2006 PaX Team

usage: paxctl

options:
-p: disable PAGEEXEC -P: enable PAGEEXEC
-e: disable EMUTRMAP -E: enable EMUTRMAP
-m: disable MPROTECT -M: enable MPROTECT
-r: disable RANDMMAP -R: enable RANDMMAP
-x: disable RANDEXEC -X: enable RANDEXEC
-s: disable SEGMEXEC -S: enable SEGMEXEC

-v: view flags -z: restore default flags
-q: suppress error messages -Q: report flags in short format
-c: convert PT_GNU_STACK into PT_PAX_FLAGS (see manpage!)
-C: create PT_PAX_FLAGS (see manpage!)

Simply copy the firefox-bin binary to firefox-secure and apply the different flags as necessary.

dynamips (Cisco 7200 Simulator) on Mac OS X

It runs pretty decently so far, just need to get couple things installed manually or via ports if available:


 $ curl 'http://www.mr511.de/software/libelf-0.8.6.tar.gz' -o libelf.tgz
$ tar -zxf libelf.tgz
$ cd libelf-0.8.6
$ ./configure --prefix=/usr/local
$ make
$ sudo make install ...
$ cd ../dynamips-0.2.5 && make
$ ./dynamips ../../c7200-ik9su2-mz.124-13b.bin
