Ever since I installed Kontact 4.5, it has been showing an MySQL warning when starting. The exact error in the logs is:

Can't open and lock time zone table: Table 'mysql.time_zone_leap_second' doesn't exist trying to live without them

While it's only a warning, I don't like to have my logs filled with warnings. Hence, I went on a hunt to prevent this warning. Lots of posts said this issue is fixed in newer versions (certainly not for me!), or it doesn't matter. But that wasn't good enough for me so I felt relieved when I found a workaround yesterday, which I shall explain below.

The Arduino is a small programmable device that can hold a small program and perform tasks such as reading temperature sensors, turning on or off switches, and can even serve as the ‘brain’ for a robot. I have used the Arduino (actually freeduino) for projects related to HVAC and hydroponics automation.

We all know that Google is huge and there are more than enough examples of people crying the end is nigh regarding the seemingly insurmountable rise of the one-time search engine. But are they really that big? Do they have that much of a hold over us and should we be worried? Read the article at Free Software Magazine.

What is SPICE? It stands for "Simple Protocol for Independent Computing Environments". What does that mean exactly? SPICE is a remote display protocol designed specifically for use with the Linux kernel's built in virtualization hypervisor KVM. SPICE is similar to terminal services but rather than multiple users sharing a single, remote physical machine, SPICE allows you to graphically connect to and use a local or a remote KVM virtual machine. I got SPICE going on a Fedora 14 host machine with a Fedora 14 KVM virtual machine. I made a 13 minute video showing SPICE in action with common apps and multimedia.

As open source adoption has ramped up in recent years--especially at businesses and organizations--Black Duck Software has steadily been extending its role in the growth, largely through a series of acquisitions. The acquisitions have transformed it from the open source auditing entity that it originally primarily functioned as into a player in the open source deployment, management and development space, and more. With its latest acquisition of the assets of SpikeSource, it is continuing that trend--all focused on open source.
