So, Ubuntu-14.04, Trusty Tahr, is out; and booting the cloud images requires a bit more hacking than booting the 12.04 cloud images. Here goes:
Get the image, resize and loop-back mount it:
Like Ubuntu, Fedora distributes cloud images and like in the case of Ubuntu (see my previous post), I’d like to boot the image without actually running a cloud. At least not an OpenStack, CloudStack or Eucalyptus cloud that is.
Again, I did not manage to find any simple recipe for doing this, but it turned out to be even … Read the rest
I was recently asking myself why the P2V concept has not been more fully embraced by the open-source community – and generalized to V2C, virtual machine to cloud instance. From a scientific computing perspective, it would be ideal to seamlessly be able to prototype a data analysis in a virtual machine on a laptop and then run large-scale data … Read the rest
Cloud storage is often used for backup, but finding myself relying more and more on cloud-only documents, I felt a need for backup in the opposite direction: backing up my entire Google Drive to local storage – preserving the folder hierarchy. I was not able to find a script that does this, so I wrote one myself. I chose … Read the rest
For a long time I’ve been looking for a note-taking app that:
1) is available as an iPhone/iPad app ✔
2) synchronizes to either my own server or Google Docs/Drive ✔
3) has a web interface
4) supports organization of notes in hierarchical folders
5) has “todo” functionality (creation and due dates) ✔
6) allows assignment of priorities ✔
This … Read the rest
Since my last post about SqueezeScrobbler on my Squeezebox, I’ve enjoyed 3 years of LastFM listening on Squeezeboxes, Linux and Mac boxes, iPhones and iPads.
Well, this fall, LastFM announced that they would hit my listening pleasure with dual strikes: deprecation of the old API and discontinuation of the radio service in other countries than the US, UK and Germany. … Read the rest
I’m quite happy with my small HTPC running Boxee on Ubuntu. The hardware is a Zotac Ion board with an Atom CPU and an Nvidia graphics card. Both software and hardware have their issues, but after enough hacking I’ve a setup that gets the job done wrt. watching movies off my file server. My main gripe has been the lack … Read the rest
This is a follow-up post to my previous post “Front door locks”.
I’m happy to announce a little utility that exports TCS certificate/keys to the hard disk – more precisely to your “.globus” directory where grid tools expect to find them.
Here follows instructions on how to use it:
First, you of course need to have some TCS credentials … Read the rest
When my family and I recently moved into our new apartment, it was equipped with a front door with two locks: both of them with a spring latch. To get in, we needed to put a key in each and turn both while somehow turning the door handle at the same time. It could take quite a while … Read the rest
Updated the Collapse plugin to work with IE.
Just updated the Collapse plugin a bit: when linking to anchors deep inside collapsed sections, the parent are unfolded all the way up, so the anchor is actually shown.
* Positioning on the page after (un)folding can be somewhat imprecise on large pages. If you don’t need persistence, you can turn it off in the script … Read the rest
JQuery based WordPress plugin for collapsing/hiding and expanding/showing sections of posts and pages.
I’m a long-time and happy Sage user, but since I’m more and more starting to use Chrome and Safari, not to mention my iPhone, the lock-in on Firefox is becoming a problem. I’d like to read my feeds in the bus on the way to work or while drinking my morning-cafe-latte.
Until recently I couldn’t find anyone who had solved … Read the rest
I’ve been missing LastFM on my Squeezeboxes for quite a while (see this and related posts), so I was excited to see this post, announcing support for the new LastFM service.
Unfortunately, I had already upgraded my Squeezebox server to the latest server software release (7.4) and the new SqueezeScrobbler-1.2.6 (available from here) did not work for me … Read the rest
Just in case anyone else is pulling their hair over Ubuntu regularly/automatically changing/reverting passwords set with smbpasswd:
If you don’t want passwords changed by any other means than smbpasswd, uninstall libpam-smbpass and disable “unix password sync” in /etc/samba/smb.conf.
I usually spend some evenings in the quiet days between Christmas and new year to clean up my personal information stuff and this year is no exception. After many years of increasing amounts of emails per year, this year the number of both received and sent mail seems to have stabilized. Anyway, this year is a bit special, in that … Read the rest
UPDATE: mod_gacl is now distributed with GridFactory
Ever wanted to:
- use Apache as a secure file server,
- use X.509 certificates for authenticating both server and client,
- control who can put and get files in each directory?
Well, then go right ahead and download mod_gacl.
Installation: Follow the instructions in the README file. Since an … Read the rest
This post is just in case someone else tries to get WP-DownloadManager to work under WPMU with subdirectories (as opposed to subdomains).
I had to follow the advice given here and replace
in the Download Templates.
Moreover I had to choose “Redirect to File” under “Download Options” and of course use a directory that was actually served.
Image rollovers in WordPress posts?
Not the most obvious thing to have in blog posts, but rollovers can be nice to have on static pages – especially if you use WordPress to build full web sites.
I would’ve thought someone had already done a plugin for this, but was not able to find one. So this afternoon I threw one … Read the rest
