Bootstrap and HTML5 game engines

I found some new stuff that is usefull for Bootstrap and Jekyll:

End-of-the-year review

I had many private and business topics in 2014, but there have been just a few posts in my blog. I worked a lot with OpenVZ virtualization and I’m using it now beside Xen for some virtual machines. I like OpenVZ so far and I’m looking forward to the merge of OpenVZ and Parallels Cloud Server into a single common open source code base.

For the migration of Xen DomUs I needed to move some LVM-Volumes. I learned how to use Bootstrap to create some websites. I learned about using Jekyll for static website generation. I had a look at the Ghost blogging software, but I did not use it for production purpose.

I had no problems with DNSSEC this year. My bind and PowerDNS setups worked all fine. The automated key rollovers with OpenDNSSEC worked too, even with registrar domain update.

Last but not least something that kept me busy in my job: the new gTLDs. I’m looking forward to see what will happen in 2015, e.g. how many domains will be renewed after the first year.

Move LVM logical volume to other server

When using LVM, there will be sooner or later the time when you want to move an existing LVM volume to another server. I used this twice:

dd if=/dev/volumegroupname/logicalvolume bs=4096 | pv | gzip | \
ssh 'gzip -d | dd of=/dev/volumegroupname/logicalvolume' bs=4096

Source: Serverfault: Moving a Logical Volume directly from one server to another over the network?

Please check that the required packages are installed, for Debian use this line:

apt-get install coreutils gzip openssh-client pv

For creating a logical volume you can reffer the LVM HOWTO for this or a nice German LVM reference.

Using Bootstrap and Jekyll for static websites

Bootstrap quickstart

I wanted to build some small websites without using a PHP based CMS or blogging system and I didn’t wanted to care about the CSS either. I found some websites made with Bootstrap and gave it a try. The framework is easy to use and reduced my work to inserting some HTML to the template. For single pages, this was a perfect solution for my needs.

Building static websites with Jekyll

For some websites I wanted to have more than one page. I split the page into header, content and footer. This needed PHP again to merge the parts together. To allow hosting on smaller virtual machines, I didn’t wanted to use PHP. By googling I found Jekyll as a possible solution.

Jekyll is a generator for static websites, that can be used for blogs, too. Perhaps these links are helpful for others to start with jekyll, too.

I’m still doing my first steps with this system. It looks great, but I need to have a look at minor problems.
