When you stand over your child’s dead body

Christoph — Wed, 26 Aug 2009 04:31:59 +0000

Got this in today’s Grace Gem. The quote is by C.H. Spurgeon. May you so live, that when you stand over your child’s dead body, you may never hear a voice coming up from that clay, ”Father, your negligence was my destruction! Mother, your prayerlessness was the instrument of my damnation!“ “Impress these words of Mine on your hearts [...]

Be filled with the Spirit

Ever wonder what it means to be filled with the Spirit? Paul explains it clearly in two parallel passages in Ephesians 5 and Colossians 3

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 [...]

Audio Amplifier

Christoph — Mon, 25 May 2009 15:00:39 +0000

Just wanted to get this out there before I forget about it, so I won’t have the schematics up. This is your basic audio amplifier without any filters or fancy stuff. The little breadboard on the right has the pre-amp stage, a simple inverting op-amp amplifier with a gain of 4 V/V or so to get [...]

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 [...]

Not just doing, but attitude

Christoph — Fri, 24 Apr 2009 15:38:23 +0000

I am reading in 1 Chronicles right now and just finished the last chapter. David’s prayer in 1 Chronicles 29:10ff reminded me of Jesus’ Sermon on the Mount, where he raised the bar from simply doing to the intentions of the heart. Don’t just not commit adultery, don’t lust in your heart, either. Don’t just [...]

Poll oddities

Christoph — Thu, 09 Apr 2009 02:32:38 +0000

It seems like over 61% of Americans feel like this country is headed in the wrong direction, but at the same time, 60% approve of Obama’s performance. I realize that Obama isn’t the only one running this country, but it appears to me that he has the most influence on what’s happening right now and what [...]

Matlab Goodness for System Analysis

Christoph — Fri, 03 Apr 2009 03:59:42 +0000

This is mostly for my own reference, but I hope someone else will benefit from it. It’s mainly to play with transfer functions. First, generate the transfer function: % numerator coefficients for s^2 + 2s + 4 num = [1 2 4] % denominator coefficients for s + 6 den = [ 1 6 ] % build the transfer function H = [...]

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 [...]

Xdebug on OSX Leopard with Entropy PHP5

Christoph — Sat, 21 Mar 2009 15:02:57 +0000

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 [...]
