Caveats of the fullscreen API

My example for WebGL and the monitor test use a canvas element for display. In addition there is an option to switch to fullscreen mode. Technically this is achieved by using the fullscreen API. The implementation is always the same:

  1. When clicking the button fullscreen mode the canvas element will be changed to fullscreen by using requestFullscreen().
  2. A handler which reacts to fullscreen changes corrects the width and height of the element to the screen size taking window.devicePixelRatio into account to support the native resolution of the device.

OnlyOffice in Nextcloud – the current status

I recently reported hastily that OnlyOffice in Nextcloud would generally no longer work properly.

However, this is generally not correct and I did premature conclusions for some points. Ascensio System also got in touch with me and did everything possible to help me with my problems – thank you!

I removed the original post because it was based on incorrect assumptions.

“Retro” High End

Recently a good friend of mine gave me a used Intel Xeon E5-1650 v2 which he didn’t need any longer as a gift. According to the data of Intel this model was already introduced in the third quarter of 2013 and is therefore 7 years old as of August 2020.

Calling this “retro” may be a bit exaggerated – but it is a valid question if using such an old processor still makes sens in the year 2020. Current models provide more performance while also often using less power. In addition memory modules with DDR4 provide a higher throughput as well.

On the other hand my old PC is still mostly based on the hardware with Xeon E3 which I bought already in 2014 and which got equipped with SSDs as mass storage and a new graphics card running a 4K display. Despite its age it is still usable quite well. Moving to the Xeon E5 would be an easy upgrade since I only would have to change the mainboard and the CPU cooler. The existing RAM modules could be used unchanged.

Nextcloud Talk: “High Performance Backend” now Open Source

Nextcloud Talk is an extension for Nextcloud that enables chats as well as video conferencing. A decent browser and a webcam are sufficient to use that. You can also use an app for Android or iOS.

With a few simultaneous connections this usually works quite well if you pay attention to a few points, such as using a server for STUN/TURN like coturn (I will write a separate article about this).
