Recently someone informed me via Github about a copy of Periodical on Google Play, which was published as “Period Tracker” – however without the modified source code and without mentioning the original source, which is a clear violation of the GPL.
After a longer break I finally extended “Periodical” by the functions which already have been planned for a while:
- single days can be added to a period or removed from a period individually.
- days of the period can be marked with an invididual intensity.
- the calendar shows the current day of the cycle.
- you can add notes and symptoms to every day in the calendar.
If you are using wireless mice and keyboards you should be aware of the risks. Also see this article at Computerworld.
At least Logitech provides a firmware update which fixes the problems:
The program also checks if there is an update needed at all. So I found out that even the Unifying Receiver of a new keyboard (K270), bought in January 2018, was still shipped with an outdated firmware.
Only when the update tools displays a message that all found devices are up to date, there is no risk.
For a long time there had been an SVN archive of Thing at atariforge.org. Unfortunately this website is not online any longer. But I’m happy to announce that the commit history of the SVN archive could be rescued and the sources are now available at Github: https://github.com/arnowelzel/thing
Thanks to Miro Kropáček for his support in preserving the commit history from the old SVN repository.
Recently details of two security problems got published which allow to bypass protection mechanisms of CPUs to get access to sensitive data – known as “Meltdown” and “Spectre”.

Sometimes I need to check the function and picture quality of displays. Usually this is done by using some kind of test software – but you can not always install or run software, for example when Linux is installed but the test software is only available for Windows.
In the latest version I also fixed some problems for full screen mode, so every modern browser should be usable for the test.
In August 2017 I had the opportunity to meet Prof. Jim Austin and visit his “computer sheds”. Jim Austin is a professor of computer science and has a very extensive, private collection of computers that he has collected in his warehouses over many years.
The collection is not (yet) a regular exhibition, but if you register in advance, you can get a private tour for a little donation. Also see http://www.computermuseum.org.uk. Below is a loose collection of pictures I took during my visit.
My special thanks go to Jim Austin and Trevor Howard-Smith for the friendly guidance and to the many people helping with cataloging and preparing the collection!
In the context of the current discussion about sexual abuse in the film industry, a film produced in 2014 has also been re-staged which looks at the abuse of children in the California film industry and that no distributor wanted to have in the program at that time – “An open secret”.
You can watch this film on Vimeo: https://vimeo.com/142444429
In the past I have used the plugin “Responsive Lightbox” for the enlarged display of pictures. Unfortunately, this solution had some weaknesses:
- No possibility to enlarge the picture view.
- Swipe gestures are quite “jerky” – you can see how the picture view follows the finger movement very slowly
In particular, I noticed the lack of the possibility of image magnification on another website, where I have seen people who have tried to enlarge individual images with the common two-finger gesture on their smartphones.
Some time ago, a severe security problem was discovered in Bluetooth devices, which had been given the name “Blueborne” by their discoverers. Operating systems like Linux and Windows already got security updates. Android is theoretically also fixed already – however, only by Google and the devices sold under their name. For devices from other manufacturers the situation is worse if the device has been on the market for more than 2 years.
