Copying Files between S3 buckets. Juli 8, 2010 at 12:27 pm · Filed under AWS. Building on this article. Here is a simple ruby script, that copies files between two buckets of the same S3 account, omitting files already present (by name). This variant adds a list of path prefixes, so you can selectively copy only certain directories of your buckets. Furthermore it copies the original buckets ACLs for each key.

MoMolog » Connecting to redis via SSH tunneling

Connecting to redis via SSH tunneling. Dezember 2, 2011 at 12:46 pm · Filed under Allgemein. SSH tunneling is, of course, useful for a ton of services, but I happened to stumble upon it, when I wanted to connect to a remote redis server. If you have a redis server running on [remotehost], you can easily connect. To it (given you have ssh access to it, of course) via:. Ssh -L 9999:localhost:6379 [remoteuser]@[remotehost].

MoMolog » Using throw and catch to tidy up our code
http://momolog.info/2012/03/29/using-throw-and-catch-in-controllers
Using throw and catch to tidy up our code. März 29, 2012 at 12:17 pm · Filed under Rails. Let’s say we want a simple controller action that checks, if a given code is valid. It should return true and false and, if the code is invalid, give the reason (whether that is because it is unknown or because it has been used already). The action could look like this:. Now this deep nesting effectively hides the underlying algorithm, a simple one in this case. Straightens the code a bit:. We are down to one.

MoMolog » MySQL BEFORE INSERT trigger as check constraint

MySQL BEFORE INSERT trigger as check constraint. Oktober 21, 2009 at 11:03 am · Filed under Allgemein. Since MySQL does neither have real check constraints nor a way to raise an exception in a stored procedure, we found it not instantly obvious, how we could *reject* a certain row on insert, based on a certain condition. A nice way we found was to set the value in question to NULL, based on the condition and let the NOT NULL constraint do its work. E-mail (required, not published! Kurse suchen – St...

Push local branch to specific heroku app. November 28, 2011 at 7:33 pm · Filed under Note to self. You use two heroku apps as staging and production for your project. You added both as git remotes, e.g. „production“ and „staging“. Now you want to push your local branch „poster“ to remote „staging“, use. Git push staging poster:master. Note, that you can only push to „master“ on herokus side. This is just git syntax, but I keep forgetting it, so here it is for future reference. Theater und Orchester GmbH.
