In my blog post CernVM: how to set up a local ATLAS Software Release, I presented a brutal approach how to override CVMFS (CernVM‘s filesystem with HTTP backend) to install a local ATLAS Software release. Now I worked out a very clean and smooth solution. This approach allows: to use the local ATLAS Software without [...] During development, a system running ATLAS Software has to be tested and validated. There are some standard tests that almost don’t need any input data, stress the system and — if they run properly — are a (very) good indicator that everything is set up correctly. I talk about the so-called JobTransforms. By combining these [...] In CernVM: local ATLAS Software — the clean solution I proposed to install an ATLAS Software release to an EBS volume. I did it to make it locally available in CernVM running on EC2. The approach allows to move an EBS volume from one EC2 instance to another without losing important components and functionality. Here [...] Today I wanted to submit a bug for Google (XML) Sitemaps Generator for WordPress. WordPress.org offers a Trac Ticket System under http://plugins.trac.wordpress.org. Obviously, a new ticket cannot be submitted anonymously, so you have to log in. But I could not find any hint about how to register for a new account for this system. [...] In this blog post I dedicate myself to the definitions and differences of SOAP, Query and REST API you can use to manage Amazon Web Services. By reading a good book, I could solve some confusion and find answers on upcoming questions. It turns out that Amazon does not use consistent API terms. I would [...] One of the main features of CernVM is its special filesystem CVMFS with http backend (based on FUSE). Using CernVM in the standard way, the different experiment softwares work out-of-the-box and are made accessible over the web via CVMFS. Although this is a great feature, I like to set up an ATLAS Software release locally [...] While installing an ATLAS Software release from Boston University’s mirror, I discovered a broken archive file. It was the fault of a bad network card. The mirror had to be rebuilt from scratch. [...] In the past days I tried to set up CernVM on a Nimbus cloud to get an ATLAS Software Release (local version) running. On this way some problems came up. One of them could be solved by instructing the Xen hypervisor to choose the proper Linux kernel. [...] Hello everyone out there! In the past weeks I spent some time on creating a new website behind gehrcke.de. Now it’s released to the public. [...] I am using the Atahualpa Theme and I think it’s annoying to get an outline around the header image while clicking on it by default. The outline is the dashed line around the header image that appears when you press your mouse button down while hovering over the image (at least in Firefox 3). There [...] | |
