Making ixquick your default search engine

In this writer’s opinion, it is vitally important that we take reasonable measures now to help insure anonymity, lest we create a situation where privacy no longer exists, and the simple want of, becomes suspicious.

Here’s how to configure your browser to automatically use a search engine that respects your privacy.


  1. Click Settings.
  2. Click “Set pages” in the “On startup” section.
  3. Enter https://ixquick.com/eng/ in the “Add a new page” text field.
  4. Click OK.
  5. Click “Manage search engines…”
  6. At the bottom of the “Search Engines” dialog, click in the “Add a new search engine” field.
  7. Enter
  8. Click “Make Default”.
  9. Click “Done”.


  1. Click the Tools Menu.
  2. Click Options.
  3. Click the General tab.
  4. In “When Firefox Starts” dropdown, select “Show my home page”.
  5. Enter https://ixquick.com/eng/ in the “Home Page” text field.
  6. Click one of the English options here.
  7. Check box for “Start using it right away.”
  8. Click “Add”.


  1. Click “Manage Search Engines
  2. Click “Add”
  3. Enter
    Name: ixquick
    Keyword: x
    Address: https://ixquick.com/do/search?lui=english&language=english&cat=web&query=%s
  4. Check “Use as default search engine”
  5. Click “OK”

Internet Explorer:

      _     ___  _ __        ___   _ _____ ___ 
     | |   / _ \| |\ \      / / | | |_   _|__ \
     | |  | | | | | \ \ /\ / /| | | | | |   / /
     | |__| |_| | |__\ V  V / | |_| | | |  |_| 
     |_____\___/|_____\_/\_/   \___/  |_|  (_) 
    (This is not a good strategy for privacy.)



You are now one step closer to not having every motion on the Internet recorded.

This is a relatively small measure, though. You can improve your resistance to prying eyes (e.g., browser fingerprinting) by using the Torbrowser Bundle, or even better, Tails, and routing your web usage through Tor, i2p, or FreeNet.

Debugging PHP with Xdebug

I have finished (more-or-less) making a demo for the Xdebug togglin’ add-on/extension that I’ve developed.

One hundred percent of the feedback about this project has been from Chrome users. Therefore, the Chrome extension has advanced with the new features (v2.0), allowing selective en/dis-ableing portions of Xdebug’s output. That is you can set Xdebug to firehose mode (spitting out everything) and then squelch anything not immediately needed at the browser layer. The other information remains present, hidden in the background, available if you decide that you need to have a look.

The Firefox version is still at v1.2 but will be brought up to speed as time permits.

If you want that firehose mode for Xdebug, here’s a sample of some settings for your configuration ‘.ini’ file.

The demo is here.

Git: an untracked mess?

There may be times when you find your Git repository burdened with scads of untracked files left aside while twiddling, testing bug patches, or what-have-youse.

For the especially scatter-brained among us, these things can go unchecked until a day when the useful bits of a git status scroll off the screen due to utterly unimportant stuff. Well, hopefully unimportant.

But we’d better not just cleave away everything that we haven’t checked in. You wonder:
What if there’s something important in one of those files?

You are so right!

Let’s fix this!

Firstly, we want a solution that’s reproducible. Only want to invent this wheel once, right?

Let’s begin with the play-by-play:

Git, we want a list of what isn’t tracked: git ls-files -o --exclude-standard -z

We’ll back these files up in our home directory (~), using CPIO but we don’t want a poorly-named directory or finding anything will become its own obstacle. So we’ll take use the current date (date +%Y-%m-%d), directory (pwd) and branch we’re using (git branch) and we’ll twist all of it into a meaningful, but appropriate, directory name using sed. git ls-files -o --exclude-standard -z | cpio -pmdu ~/untracked-git-backup-`date +%Y-%m-%d`.`pwd | sed 's,^\(.*/\)\?\([^/]*\),\2,'`.`git branch | grep "*" | sed "s/* //"`/

Then Tell Git to remove the untracked files and directories: git clean -d -f

Ahhhh… Much better. Is there anything left out? Perhaps. What if we decide that moving these files away was a mistake? The kind of mistake that breaks something. If we realize right away, it’s easily-enough undone. But what if we break something and don’t notice for a week or two? It’d probably be best if we had an automated script to put things back the way they were. Let’s do that.

Simple enough. We’ll just take the opposite commands and echo them into a script to be used in case of emergency.

Create the restore script (restore.sh), to excuse faulty memory: echo "(cd ~/untracked-git-backup-`date +%Y-%m-%d`.`pwd | sed 's,^\(.*/\)\?\([^/]*\),\2,'`.`git branch | grep "*" | sed "s/* //"`/; find . -type f \( ! -iname 'restore.sh' \) | cpio -pdm `pwd`)" > ~/untracked-git-backup-`date +%Y-%m-%d`.`pwd | sed 's,^\(.*/\)\?\([^/]*\),\2,'`.`git branch | grep "*" | sed "s/* //"`/restore.sh

Make the restore script executable: chmod u+x ~/untracked-git-backup-`date +%Y-%m-%d`.`pwd | sed 's,^\(.*/\)\?\([^/]*\),\2,'`.`git branch | grep "*" | sed "s/* //"`/restore.sh

Lastly, the magic, compressed into one line that will stop if any command does not report success: a='untracked-git-backup-'`date +%Y-%m-%d`.`pwd | sed 's,^\(.*/\)\?\([^/]*\),\2,'`.`git branch | grep "*" | sed "s/* //"`; git ls-files -o --exclude-standard -z | cpio -pmdu ~/$a/ && git clean -d -f && echo "(cd ~/$a/; find . -type f \( ! -iname 'restore.sh' \) | cpio -pdm `pwd`)" > ~/$a/restore.sh && chmod +x ~/$a/restore.sh; unset a

Zsh and hash

Documentation for this one seems a bit hard to come by but it is one of the things I love about Zsh.

I’ve seen many .bashrc files that have things like:
alias www='cd /var/www'
alias music='cd /home/j0rg3/music'

And that’s a perfectly sensible way to make life a little easier, especially if the paths are very long.

In Zsh, however, we can use the hash command and the shortcut we get from it works fully as the path. Other words, using the version above, if we want to edit ‘index.html’ in the ‘www’ directory, we would have to issue the shortcut to get there and then edit the file, in two steps:
> www
> vim index.html

The improved version in .zshrc would look like:
hash www=/var/www
hash -d www=/var/www

Then, at any time, you can use tilde (~) and your shortcut in place of path.
> vim ~www/index.html

Even better, it integrates with Zsh’s robust completions so you can, for example, type cd ~www/ and then use the tab key to cycle through subdirectories and files.

On this system, I’m using something like this:
hash posts=/home/j0rg3/weblog/posts
hash -d posts=/home/j0rg3/weblog/posts

Then we can make a function to create a new post, to paste into .zshrc. Since we want to be able to edit and save, without partial posts becoming visible, while we are working, we’ll use an extra .tmp extension at the end:
post() { vim ~posts/`date +%Y-%m`/`date +%Y%m%d`.$1.txt.tmp }

[ In-line date command unfamiliar? See earlier explanation ]

But, surely there is going to be a point when we need to save a post and finish it later. For now, let’s assume that only a single post will be in limbo at any time. We definitely don’t want to have to remember the exact name of the post — and we don’t want to have hunt it down every time.

We can make those things easier like this:
alias resume="vim `find ~posts/ -name '*.txt.tmp'`"

Now, we can just enter resume and the system will go find the post we were working on and open it up for us to finish. The file will need the extension renamed from .txt.tmp to only .txt to publish the post but, for the sake of brevity, we’ll think about that (and having multiple posts in editing) on another day.

Deleting backup files left behind by Vim

It’s generally a great idea to have Vim keep backups. Once in awhile, they can really save your bacon.

The other side of that coin, though, is that they can get left behind here and there, eventually causing aggravation.

Here’s a snippet to find and eliminate those files from the current directory down:

find ./ -name '*~' -exec rm '{}' \; -print -or -name ".*~" -exec rm {} \; -print
This uses find from the current directory down (./) to execute an rm statement on all files with an extension ending in tilde (~)
Alternatively, you could just store your backups elsewhere. In Vim, use :help backupdir for more information.
