What is going on at the Sun?

Saturday, February 2nd, 2019

In the randform blog post Information about solar irradiance measurements sought, I had posted a visualisation of irradiance data from the Laboratory for Atmospheric and Space Physics (LASP). In the post it was discussed that there could be a rise in irradiance based on the data from their SORCE mission. I think the rise is also somewhat visible in this interactive plot at the Interactive Solar Irradiance Data Center (LISIRD)…that is it is visible until about July 2015. In this post I also posted a picture of the line 774nm, i.e. “red light” which is slightly out of the visible spectrum. The reason was that it seemed that specific line ranges displayed a stronger rise than others (see circles in the other image in this post). Back then I even made some screenshots from the LISIRD visualization, here you can see the close-by line 798.83nm:

Here it is again in my visualization:

Both visualizations look pretty much the same apart from some visualization effects. But this is how the line in the above time range (here until Dec 18 in 2016) looks as of today in the new LISIRD app:

So things look very differently since about early summer 2015. Is this a correction?

ShutterSploshScatterPlots

Friday, September 29th, 2017

Mohammad Ali (mohdali) had made a nice illustration of the socalled rolling shutter effect. He wrote a programm in javascript which uses the library d3 called Rolling shutter.

This program was used by artist Scriptique to program a kind of “paint-by-number recreational occupation for your browser” (as the artist called it). It should display something like “a paint drop dropping”.

The program has a MIT licence and you can see how well your browser paints by numbers by pasting the program into a file and then opening the file in your browser (tested with firefox).

AccèsCotes

Monday, July 31st, 2017

AccèsCotes is a new experiment within the series “body control”, which explores amongst others (dance-like) body movements as computer-input languages.
The principle tongue-in-cheek idea behind it was to self-enforce more body movements via placing the “buttons” of a keyboard on different garment items/accessories (like by e.g. having the buttons for the vowels on a bag, the delete button on another accessory and the rest on the trousers). The experiment was invited to participate at the Berlin Fashion hackday 2017.
In the xOSC Keygloves input was made via conductive contacts and in the gesture steered Turing machine the input was made via hand gestures and their screening via bend sensors, this time capacitive sensors were used.

Before and after

Friday, February 24th, 2017


You might remember the randform post “Death of a pub” about the demolishment of a traditional Berlin pub/restaurant/dancehall. Meanwhile the restaurant got replaced by a building which provides room for two small facilities. One of the facilities, which hosts currently a little pub called “Schranke” (“barrier” or “level-crossing”) has a little beer terrace/garden next to the buidling. The other business sells Doner kebab and is called “Dönerhaus”. The former garden of the restaurant had been integrated into a parking lot. The images below and above display the new public space situation at the station. Judge yourself whether this is an improvement.
