The following works great on Rackspace’s Debian Virtual Servers and within 5 minutes you got a running rails instance.

I’ve pretty much come to rely on git to pull me out of any bad jams in the chaotic environment I work in.

One thing I’ve had to learn to do is cherry pick commits and package them under a tag in git.

Here’s how to do it if you were working with my newLISP project called Sitebeagle:

fork sitebeagle on this page

cd sitebeagle

git fetch –tags

git checkout 8f5bb33a771f7811d21b8c96cec67c28818de076

git checkout -b sample_cherry_pick

git cherry-pick 22aab7

git cherry-pick b1334775

git diff sample_cherry_pick..master

git tag leaving_out_one_commit

git push origin –tags

At this point, you should have a tagged branch that doesn’t have the commit with the change to the “2nd file.” The diff should look exactly like this:

diff –git a/test.lsp b/test.lsp
index 9cf1667..158b625 100755
— a/test.lsp
+++ b/test.lsp
@@ -1,6 +1,7 @@
#!/usr/bin/newlisp

; test tag test_a
+; cherry pick test 2

(load “sitebeagle.lsp”)
(load “twitter.lsp”);

For checking up on sites in the enterprise, I use Alertsite. It was suggested to me by a VP I work with at McCann, Ed Recinto. It’s been a great tool.

For personal websites that I manage, I’ve been using something I rolled in newLISP, sitebeagle. Why? Because beagles are great watchdogs.

Very often, most problems can be solved with tweaking code, changing permissions, or upgrading and apache or mysql.

Very often, it’s the weekend, I’m sitting in a cafe, and get an alert from Nagios or Alertsite. With iSSH, on the iPhone, I can ssh into a LAMP server and do the work I need.

I can see things getting a bit more complex. What tools do you use to sysadmin from an iPhone?

Alan Kasindorf just introduced me to a great blog by Eric Day, Oddments.

If you are into learning about alternatives to MySQL like Drizzle, or how to scale writes to a database using Gearman, then I wholeheartedly recommend his blog.

I really like the samples of code he puts up that acts as a very useful, and direct tutorial to new technologies.

How fast can you get on the web? With newLISP it’s about as fast as typing:

How fast can you create a backdoor with newLISP?

If you telnet into port 1234 in localhost, you’ll see something that looks like this:

This opens up a lot of possibilities for distributed computing.

For example, you can set up a newLISP server that’s ready to respond to a newLISP client with this command:

Your newLISP client can have code that sends a computing problem to be solved to the server:

Or let’s say you had a farm of newLISP servers:

If the above example reminds you of Gearman, you get +12 points.

If you work with ACL, this may be the most important video you watch ever. Zed shows how ACL is not Turing complete, which explains all the problems you’ve been having with control lists.

Pre-requisites:

• An EC2 account. Click on the sign-up for ec2 button.
• Some version of *nix.
• Download the ec2 tools.
• Generated an ec2 keypair.

Now we’re ready to build an EC2 LAMP Server.

You’ll find that a lot of ec2 stuff happens in the .ec2 directory.

To list the possible servers that you can set up run:

I ran

and got 1477 possible servers. Some are Windows.

Let’s say we see this listing:

If we want to start up the ubuntu server listed above we just type:

And then we run this command:

We should see either “pending” or the actual instance running with its FQDN listed in the 4th column. An example FQDN is this:

ec2-173-33-159-95.compute-1.amazonaws.com

And if we go to:
http://ec2-173-33-159-95.compute-1.amazonaws.com/

we should see a webserver.

And if we ssh:

we’ll get the root prompt:
#~

That’s basically it. Now you can go in and mess around with server settings.

In the next blog post, we’ll look at how to save your custom server settings and set up using S3.

I wrote this quick script to take care of apps that seem to Crash OS X 10.5.5 on my Macbook Pro. I have just 1GiB of RAM instead of the recommended 2GiB, but ever since killing the processes in the script below, I haven’t had a crash.

The bad guys are:

• Google Updater
• Cross Over
• HPEventHandler
• HP IO Classic Proxy
• HP IO Classic Proxy 2

I killed privoxy in my script below just to get more memory to run Warcraft.

Create and edit a settings.yml file. Mine looksl like this:

Hey folks, this is a goody but quicky.

First off, respect the character encoding of a file. I don’t know how many devs out there violate this rule, but if you’re like me and Joel On Software, you’ll agree that you should respect the character encoding of a file.

If you happen to see that your file has gotten code page 1252 aka Windows-Latin 1 in it, then you’ll have a variety of random characters like ^M or ?~@~Y or ?~@~\ or ?~@~] .

Well, I wrote a script that removes these guys and makes sure that the file format of Unix is respected. Here it is:
