Many years ago I discovered Renoise – a so called “tracker” to create music on the computer. Eventhough I haven’t really looked into this I still have a valid license and checked if the project still exists.
Indeed Renoise is still active even after nearly 20 years. Since version 3.2 it also supports native resolution and scaling in 4K:
In June 2019 Nextcloud introduced an interesting text editor which uses Markdown as format but does not show this optically – the user interface is very tidy and text will always be shown and edited formatted. You can use Markdown syntax when entering text but in addition there is a toolbar at the top of the editor. To create a new file you can use the “+” symbol in the Nextcloud file manager as usual.
WhatsApp has a vulnerability (CVE-2019-3568) that allows unauthorized remote access to the device. The attacker can simply smuggle the spyware into a device through a WhatsApp call, even if the called party does not pick it up. Since Monday evening there is a patch.
Also, there were reports last year that WhatsApp will scan messages to show personalized ads, which is probably the case now.
These and several other events of this kind (I also recall the “Cambridge Analytica” scandal on Facebook) have kept me from installing and using WhatsApp on any of my devices and I will not do that in the future.
Those who use WhatsApp should be aware that you are potentially vulnerable. On the one hand WhatsApp’s source code is not open source, so no one knows what backdoors and security vulnerabilities exist, and on the other hand WhatsApp is also an attractive target for attacks due to the huge number of users.
Alternative to WhatsApp
As an alternative I can recommend “Signal”. This is a free messenger whose sources are also disclosed and which is also recommended by security experts. Even Edward Snowden uses and recommends this app. As with WhatsApp, the mobile number for logging in and contacting other people is sufficient, whereby the operator of Signal does not have access to this data and all messages are encrypted and can only be read by the persons involved.
For synchronizing address books and calendars on my Android smartphone I’v been using DAVDroid for quite a while. It is Open Source and also available on F-Droid. However it is now called DAVx5 – why?
The reasons are explained in this tweet – using “droid” as part of a name violates a trademark of Lucasfilm. Also see this extensive article at Priceonomics. Therefore the creator of DAVDroid decided to change the name to “DAVxxxxx” and replace “xxxxx” by “x5” – even though the official statment says something different ;-).
In the 1980ies the BBC explored the world of computers as part of the national initiative “The Computer Literacy Project” and produced numerous programs for almost a decade.
This material is now available as an archive where you can watch all the old programs again. You can also run the software developed in the past for the “BBC Micro” in an emulator directly in your browser:
Probably everybody knows public displays which are composed of segmented characters.
On https://aresluna.org/segmented-type/ you find an emulator for that which displays different variations from 8 to 93 segments per character. You can type any text on your own and select different display variations with the displayed text.
Does anyone still remember the time when the first pinball machines started using 14 segment displays which allowed to show not only the current scores but also any kind of messages?
