drm | Direct Rendering Manager in pure Go | Graphics library

Many thanks to @Sanjid above, here is the working solution (tested with a Client Side Video Player).

I found the solution and now Kubuntu starts up normally as expected.

First, I purged all drivers and libraries

Adding iommu=pt intel_iommu=on to the grub solve the softlockup and the 10 G Rx

With data.table, use melt after doing the filtering and grouping

As we are using data.table, data.table join could be faster

The mpd or m3u8 files are just manifests or index files. They are text based containing information about the video and links to the media, i.e. the audio, video, subtitles etc streams.

If you want to download a HLS or DASH stream for offline playback, you will need to download the manifest and the media streams they refer to.

ExoPlayer provides functionality to help you download video and take care of much of this complexity, including specific information on downloading HLS and DASH videos - see the ExoPlayer documentation:

• https://exoplayer.dev/downloading-media.html#downloading-and-playing-adaptive-streams

Note the section around tracks selection and bit rates - typically you will want to choose a particular bitrate to download rather than downloading all available ones:

For streaming playbacks, a track selector can be used to choose which of the tracks are played. Similarly, for downloading, a DownloadHelper can be used to choose which of the tracks are downloaded.

To support encrypted streams you need to ensure that the DRM server supports persistent licenses for that content and the entitlements allow offline playback - you will generally need to speak to your DRM provider to confirm this.

is it allowed at all to use NAN and INFINITY under non-default rounding modes, such as FE_TOWARDZERO and FE_DOWNWARD?

The language specification does not express any limitation on using INFINITY. A conforming implementation must therefore accept it and interpret it consistently with the provisions of the language specification regardless of rounding mode. Specifically, it

expands to a constant expression of type float representing positive or unsigned infinity, if available; else to a positive constant of type float that overflows at translation time.

(C17 7.12/4)

That is not conditioned on the rounding mode in effect at any particular time. Since MSVC does have an available float representation for infinity and FLT_MAX is required to be a representation of a finite number, it is non-conforming for INFINITY to evaluate equal to FLT_MAX in MSVC, under any circumstances. Indeed, MSVC is non-conforming to whatever extent INFINITY ever fails to evaluate to a positive float infinity.

It is even more clear for NAN. The specification says that it

is defined if and only if the implementation supports quiet NaNs for the float type.

In that case,

It expands to a constant expression of type float representing a quiet NaN.

(C17 7.12/5)

If NAN is defined at all then it expands to an expression that evaluates to a quiet NaN. Period. If MSVC provides for circumstances in which it instead expands to 0.0, then MSVC is non-conforming under those circumstances.

It should be acknowledged that most, if not all, C implementations have some non-conformity, whether by default or accessible via command-line options or similar. Nevertheless, MSVC is notorious for its comparatively poor conformance among the widely used C implementations.

I think what you want is to be able to specify arbitrary columns from a dataframe to be used as Id, date1, Week, etc inside return_coef(), rather than having to use a dataframe that already has those specific column names. If so, you can use the tidyeval embracing operator, {{.
