I recently put the scripts I used in a little github repo called starcluster-image-sharpener. It’s nothing big but it’ll get you started if needed. Go get them! ;)

Introduction

First a little context:

I’ve photographed a ton recently and on one occasion I screwed things up a bit and had a lot of slightly out of focus images. I’ve tinkered with the Canon Digital Photo Professional settings to find a good level of sharpening (after noise reduction because a lot was shot at high iso (for me and my 50D, iso 1250 is a lot already)) but wasn’t happy with it. I’ve found reasonable settings for noise reduction, which makes the image a bit softer, but sharpening wouldn’t do anything to compensate let alone actually sharpen.

Introduction

Alright, this is a quick guide for the impatient but otherwise experienced linux admin/hacker/hobbyist. Some past postfix experiences might be advantageous for general understanding and troubleshoooting.

Why would I want a local postfix and relay to another smtp anyway? Simple: When my application code needs to send an e-mail, there is an SMTP server ready to accept the e-mail from me. It will then take care of everything else like re-delivery, dealing with being grey-listed and many other things. Also, if connectivity to the SES SMTP happens to be interrupted it’s no big deal because here too, the local postfix will handle re-sending for me. Nice, huh?

It’s not exactly elegant to work with request parameters in a domain class but it was necessary. I have a bunch of domain classes with “asMap” methods where they render themself into a map and cascade to other domain objects as needed. In the controller, the resulting map is given to the renderer and we get a nice json response.

So now I’ve changed some fields and in order to stay backwards compatible, I created a new apiKey (a parameter needed for all calls to my app) that distinguishes old and new clients.

Considering that Google just lost tons of their user’s E-Mails, you might want to do a GMail Backup. Also, let’s see how this will develop ;-)

… not for everyone maybe, but for me as a linux/java/groovy person it is!

you’ll need

• java
• groovy
• rsync
• ssh
• cron

I want to regularly copy files from a bunch of paths from several remote hosts to the localhost. I know nothing about arrays etc in bash to configure this stuff in a simple way but the solution I’ve come up with is simple and elegant: 

I wrote a little groovy script that generates the shell commands to be executed. the output of the groovy script is piped into bash, which executes the commands. That call of the groovy script with the piping to the bash is in a little shell script which is called from cron.
