Running Dymo Label without a Dymo Printer Attached LabelWriter

Why?  Who cares why.

What is it:
Running DymoLabel 7.x without a printer connected / installed throws up a error message like:
"This program requires a Dymo Printer. "

How to Fix it:Go to the Dymo LabelWriter 320 support webpage and look for troubleshooting -> error messages.  There is a file called ASINSTALL.EXE.  Run it on your system


The go about installing a fake printer following the screens below:


  Goodbye Error Message!

UPDATE: Modern Bash Wifi Connection Script for Linux; goodbye network manager

An update to a previous post.  This script has some more command line features, such as calling up previous saved sessions credentials from the command line and improved error handling.  Completely run from the command line.

Firefox Progress of Ongoing Downloads Revert to old style

Once again, like the pdf thing that Mozilla did a while back.  The new download window:
  • Takes up a whole tab
  • Cannot be resized
  • Blocks any bookmarks on your bookmarks toolbar

Unfortunately the only fix to the old style, aka, before FF21 is to do two things:

  • Revert from private browsing (Preferences > Privacy > History > Custom Settings)
  •  Open about:config and toogle browser.download.useToolkitUI to TRUE
Un-tick private browsing :(





The analogy is that private browsing does not remember any downloading history, so the browser.download.useToolkitUI change will not show any downloads in the old style list.

Ghostery, it's better than nothing or is it

Ghostery is probably better than nothing but several facts exist.
  1. Ghostery filters are updated by Ghostery company Evidon, Inc themselves.  This feel a little closed source for me, it means that they could white list some trackers if they felt like. 
  2. Ghostery is closed source, they claim that you can look thought their xpi package to see what is inside it, but that is like M$ asking their someone to look into their exe file to see what is inside.
  3. You may not disassemble or reverse engineer Ghostery for any purpose other than reviewing the code for personal edification, so much for trying to be open source soon...
  4. Participating in the GhostRank program (default)  This is a no-brainer.
  5. Merger, Sale, or Reorganization of Evidon
    If Evidon should ever file for bankruptcy, or have its assets sold to or merged with another entity, information Evidon receives from you, from the Website, is an Evidon asset and may be transferred.
  6. And this: http://venturebeat.com/2012/07/31/ghostery-a-web-tracking-blocker-that-actually-helps-the-ad-industry/

    "After all, the thinking goes, many ad networks sell their advertisements via real-time bidding, so they often lack a clear idea of where their tags are appearing. In short, online ad networks are just as hungry for information about web users as they are for data about themselves. Ghostery gives them that information."
    "This gives Evidon a clear target market and even clearer plan of attack: Use Ghostery users to build the tracker database, then turn around and license the data to ad networks who can use the data to bolster their own efforts."


So in essence, the use of Ghostery is helping ads networks find better and more covert ways to track you online presence and these guys are using you to make a nice little database....
I'm not bothering to go any further and look at the chatter on the wire, do not install it.  Stick with adblock-lite +Fanboy Adblock List + Tracking List + Annoyance Block List.

If you still don't get it, too bad your a sad panda.

Quick install of Linux firmware htc_9271.fw for TP-LINK TLWN422G USB Wireless



Download firmware from here or search for newer.
http://wireless.kernel.org/download/htc_fw/1.3/htc_9271.fw

sudo cp htc_9271.fw /lib/firmware/.

Plug in device and do a dmesg to see if firmware is loaded.


Works great on airodump-ng, injection is super.\

Modern Bash Wifi Connection Script for Linux; goodbye network manager

19/10/2013 Update here

This script attempts to semi-automate the wifi connection process from
the command line.  It is intended to be used on a headless / GUI-less machine without the
requirement of typing several commands for a connection.  For instance a Raspberry PI.

It works reasonably well for most applications and can handle ESSID's / passwords with spaces.

Storage of previous connection credentials is in PLAINTEXT as [ESSID].wpa files in the executed directory and in /etc/wpasupplicant.conf.
These .wpa files are used to connect to several different AP's using previously stored info.
Probably a real good idea to stop and other network managing software while running this script, for instance running "airmon-ng check kill" will do a good job.
Also in testing wpa_supplicant does a pretty good job of re-connecting a disassociated link automatically.

Operation is simple.  In the case with Debian it is:
sudo ./connect.sh wlan0

Mainly created from a combination of scripts taken from theses two
sources:
http://www.backtrack-linux.org/forums/archive/index.php/t-3367.html
AND
http://www.linuxquestions.org/questions/linux-general-1/wifi-connect-script-tested-in-ubuntu-772646/
