New iPhone app Locate! released!

Christoph — Sat, 04 Feb 2012 18:32:28 +0000

I just released my new app called Locate!. From the description:

Locate! tells you where you are, supplies the magnetic declination of your location, and the bearing and distance to your next waypoint.

And here’s a screenshot:

You can check out the website, including a link to the store, at http://locate.zerodeviation.net/.

sudo 1.7.4 with the -s flag breaks my shell!

Christoph — Wed, 08 Sep 2010 15:28:12 +0000

No it doesn’t. It just doesn’t preserve your $HOME variable, as explained in the UPGRADE file. To fix it, just follow the instructions in there and add:

Defaults env_keep += HOME

to your sudoers file. Voila!

SSH config for non-standard ports

Christoph — Tue, 09 Jun 2009 03:40:42 +0000

This is the coolest thing I have seen in a while. I frequently spend time on remote hosts via SSH, some, if not most, of which run sshd on a port other than 22. This resulted in me adding “-p 1234″ to every single ssh command I executed.

Well, no more. Today I stumbled upon SSH config. Just edit your ~/.ssh/config file and add the following to get rid of all those -p’s:

Host myserver.com
    Port 1234

Do that for all your frequently visited hosts, and you will have saved your fingers a lot of typing.

Mouse gestures in Safari

Christoph — Sat, 09 May 2009 03:50:54 +0000

Recently I switched from Opera to Safari, more precisely the Webkit nightlies. The main reason is the great 1Password password manager and form filler that takes care of all my logins and more so that I can be more secure on the web.

One of the main things I missed in Safari that I came to love in Opera are mouse gestures. I checked out the programs most often recommended, but they either didn’t work anymore or cost money now. Until I stumbled upon SafariGestures. It’s a SIMBL plugin (I use PlugSuite instead, either should work) and adds a menu item to your toolbar. From there you can set a plethora of preferences and customize it to your needs.

I actually prefer it over Opera’s mouse gestures; so far it’s been a good switch!

EDIT 4/2010: I have since switched to Chrome due to its speed and given up on mouse gestures. Safari with all the SIMBL plugins seemed just too slow.

DTrace with Entropy PHP on OSX Leopard

Christoph — Sun, 22 Mar 2009 04:01:54 +0000

Similar to Xdebug, DTrace also didn’t want to work and failed with the same error, so I tried the same trick, and it worked.

Follow the instructions from Lee Packham’s blog but configure it as a 64-bit application:

tar xzf dtrace-1.0.3fixtar.gz
cd dtrace-1.0.3+fix
phpize
CFLAGS=’-arch x86_64′ ./configure –with-dtrace
make
make install

So far so good, the module is loaded. Now let’s see if Instruments will do its thing.

Xdebug on OSX Leopard with Entropy PHP5

Since I have been struggling with this for forever and finally found an answer, here’s an attempt to spread the wealth knowledge around.

Blog: Compiling & installing Xdebug for PHP 5.2.5 (Entropy.ch build) on OS X 10.5

Just to give the web crawlers some more info, the error message was:

PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so’ – (null) in Unknown on line 0

The solution is to compile it manually as a 64-bit application like so:

CFLAGS=’-arch x86_64′ ./configure –enable-xdebug

Hope this helps someone out there.

JS error in IE7

Christoph — Thu, 31 Jul 2008 22:30:06 +0000

Been battling with IE7 and a JS error I have been getting. We are using Modalbox for modal windows to display relogin information inside TYPO3 starting with version 4.3. In IE7 I have been getting the error “object doesn’t support this property or method” when loading content into the Modalbox.

After lots of trial and error I figured out that it didn’t like the name attribute on an input tag. Removing that, everything works fine now. Hope this will save someone a lot of trouble.

Christoph, who has high hopes in IE8 standards compliancy.

The epitome of connectedness

Christoph — Mon, 28 Jul 2008 19:28:39 +0000

The ultimate in total connectivity: posting a blog from my iPhone and broadcasting that to twitter and facebook at the same time. Wow…

Yay for technology

Christoph — Fri, 25 Jul 2008 16:34:17 +0000

This will demonstrate not one but TWO neat technologies. This post is written on my iPhone with the new wordpress app and should be sent to twitter as well! Let’s see if it works… By the way, my Twitter username … Continue reading →

Postfix queue management

Christoph — Thu, 26 Jun 2008 23:20:12 +0000

This is more a reminder for me than anything, but maybe someone else will benefit from this:

Print queue: postqueue -p
Delete all messages from the queue: postsuper -d ALL
Read a message: postcat -q
See what shape the queue is in: qshape

I am sure the man pages for each command will give you more info on what you can do with them.
