A further look into Google pictures tells a story without words.
Although the Japanese cherry blossom Sakura is the most famous, the Japanese plum (梅) blossom is always stunning because its happening in full winter. Often occurring right after new year, its occasionally enduring snow, with temperatures typically well below 10 degrees Celsius. Although called a plum, the fruit is closer related to apricot, and sourcing umeshu (梅酒), a sweet wine… Continue reading »View full post
Adding a battery buffered realtime clock to the Beaglebone Black provides accurate time when no Internet is available. I used an Epson RX8025NB module, and connected it to I2C bus 1. Under Ubuntu 14.04 LTS a set of rtc drivers already exists, and enabling the clock was a simple command. The biggest work was to enable I2C bus 1… Continue reading »View full post
After upgrading to Windows 10, the new Edge browser has another render engine that displays web pages “differently”, and breaks the page layout. Below is the error shown a pixel-aligned comparison screenshot of an application page, displayed side-by-side in Microsoft Edge and Microsoft Internet Explorer 11. P.S.: Take a closer look at Google Advertising. Not Photoshop inserted – With… Continue reading »View full post

Our Highlight in 2015 was being at the 11th World Karate Championship with tickets for the second day finals. Well done. Osu!
Welcome Ubuntu, Sayonara openSUSE! After the support expiration of OpenSUSE 12.3 in January, this server has just been migrated to Ubuntu 14.04.2 LTS. OpenSUSE run great during the five years, spanning versions 11.2, 11.4, 12.1 until 12.3. However the 18-month support cycle of OpenSuse required an almost annual upgrade, while Ubuntu provides longterm support versions covering five years.
Ubuntu brings back a Debian-based OS to the server, it was running Debian from its beginnings in 2004 through 2009. OpenSuse was very useful as a side operating system to Suse Linux Enterprise Server (SLES). Unfortunately my workplace no longer supports any Linux, and there is no point in sustaining SLES familiarity or knowledge.
和時計 (wadokei) are mechanical clocks telling the traditional Japanese time. Unlike elsewhere, Japan maintained a unique time system that measured day time from sunrise to sunset and night time from sunset to sunrise, splitting both periods into six units. This system created a real challenge for clockmakers. For one, the six night time units are much shorter than their daytime equivalents. Further, daylight hours vary over the year, becoming longer in summer and shorter in winter. This required a weight adjustment, done twice a month.
Foliot clocks are known in Europe since the middle ages, and were popular until the superior pendulum design took over from the 17 century. Brought to Japan by Jesuit missionaries and Dutch merchants, local craftsmen adapted European clock design to Japanese needs, adding a second foliot. This addressed the need for different clock speeds during daytime and night time.
On first glance, the face of a Japanese clock with 12 sections looks similar to European eyes. On closer inspection, it quickly turns out that 12 midnight is at the bottom, while 12 noon is at the top. Both are labeled as 9. There are no units numbered 1-3, the system starts with 4. The time units are also named after animals from the Japanese zodiac, midnight is the hour of the rat.
This model of a double foliot Japanese clock was constructed and rendered in Cinema 4D. It was build after real parts from the educational kit produced by Gakken in 2010. Klick to enlarge.
