Two opinions on Netflix and blocking: they hate Netflix or contact tr@netflix.com and try to solve …

Posted by jpluimers on 2016/03/28

Basically there are two opinions on Netflix and blocking:

  • TL;DR: People use VPNs for security, Netflix fucks them up, they hate Netflix for that and just torrent that shit.
  • tl;dr If you have issues with Netflix on public Wifi, contact the provider and forward tr@netflix.com to them so they can settle issues.

I’m not a netflix user (or user of any form of DRM) as I really dislike the fact that DRM means for any reason your license can be ended. I’ve seen too many players going out of business or taking decisions turning.

So I buy CDs, DVDs, BlueRays or DRM-free media files. Now it’s my problem of making proper back-ups to ensure future access to them (:

The DRM walls and ladders war^w game has gone so far that in this case, Netflix is blocking even though the WiFi provider / proxy / VPN is in the same country like the below imgur image:

Improve Word performance with tables

Posted by jpluimers on 2016/03/25

Apart from the obvious “use less tables” and “break tables apart”, these can also help big time:

  1. Run %WinDir%\System32\SystemPropertiesPerformance.exe
  2. Choose “Ajust for best performance” (it will disable all visual enhancements)
  3. Re-enable “Smooth edges of screen fonts” (it will make it easier to set bold and italic apart in Word)

If it is still too slow, I might look into these:

Linux-Based Low-Latency Multichannel Audio System (CTAG face2|4)

Posted by jpluimers on 2016/03/24

Just wow (via Joe C. Hecht):

Linux-Based Low-Latency Multichannel Audio System (CTAG face2|4)

We’ve developed a multichannel audio system based on the AD1938 audio codec by Analog Devices and the BeagleBone Green (TI AM335X SoC).The audio system offers 2 stereo inputs and 4 stereo outputs.The whole project is based on open source software.To demonstrate the possibilities of the audio system, I’ve created a surround delay effect with the open source C++ library DSPatch by Marcus Tomlinson.Moreover I’ve created an automatic test based on GNU octave to evaluate the audio system characteristis, such as latency, THD+N, DNR, crosstalk and frequency-response.

The latest innovation from the media – CommitStrip: @WIRED and @parool are out

Posted by jpluimers on 2016/03/24

Fun: The latest innovation from the media | CommitStrip: block visitors that use adblockers.

The real fun: the first comments G+ re-share “The end of the ad-blocking wars (and some media)”  are from people that exactly do what’s in the third frame: bye bye adblock-blocker site.

For good reason too: viewing ads has become a clear and present danger to our security and privacy.

I won’t even bother trying ad-blocker-blocker-blockers.

  1. If a site blocks me, they’re out.
  2. If they don’t block me, I share their interesting information with attribution.
  3. If they have a cookie wall that prevents seeing what I want to share, they’re out too.

@WIRED and @parool are out for reasons 1 and 3.

President of the Royal Netherlands Football Association (KNVB) Michael van Praag plays national anthems together with Adest Musica

Posted by jpluimers on 2016/03/23

Drum and Showband Adest Musica based in Sassenheim, the Netherlands, welcomes a very special guest musician. The chairman of the Dutch Football Association (KNVB), Michael van Praag, will join Adest Musica for a special performance that will take place in the Amsterdam ArenA where Adest Musica will be playing the national anthems during a friendly soccer match between the Netherlands and France.

The first contact with Michael van Praag occurred during the summer of 2015. The editors of Adest Magazine, the annual luxury magazine published by Adest Musica at the start of each New Year, had an interview with the KNVB president looming high on their wish list. Ewout Claassen, sousaphonist at Adest Musica and additionally a member of the Sponsoring Committee of the band, says: “We had learned that Michael van Praag, in addition to his work for the KNVB, UEFA and FIFA, is an avid sousaphone player. A celebrity in our own luxury magazine values it even more. These were the reasons for us to contact him. The occasion of the interview was in October 2015 at KNVW headquarters in Zeist. With a big smile, Claassen tells “Together with other interviewer Menno de Jong, who plays drums at Adest Musica and also is Sponsor Committee member, we had a very nice conversation with Michael van Praag. At the end of the event, we asked him whether he wanted to take a place in the Corps as a guest musician during a friendly international soccer match in the Amsterdam ArenA. He instantly gave his commitment.”.

Impact

Friday night March 25, Michael Van Praag will be among the ranks of Drum and Showband Adest Musica. The Corps will, prior to the friendly soccer match between the Netherlands and France, play the national anthems of both countries. Of course, van Praag will also rehearse several times with Adest Musica. Van Praag concludes “I think this is a huge honor! The Netherlands are, together with England, still the only countries in the world where the national anthems are being played by live orchestras. That always leaves a huge impression on the soccer players and the visiting association. I’m very much looking forward to the event!”.
