Seconding this, and that is one of my main points of irritation about the tech world, and the world in general. That we keep permeating outdated solutions in new articles and blog posts and elsewhere, when other actually superior solutions have been found.

> now it's 4GB larger than the versions on reddit.

Note that the first one they posted was bigger too, and in both cases, most of that extra size is coming from the following duplicate files:

  ai-programming-behavior-systems-part-01.1.zip
  houdini-director-volume-ii-part-01.1.zip
  mathematics-algebra-part-01.1.zip
  mathematics-trigonometry-part-01.1.zip
  modern-javascript-real-world-dev-part-01.1.zip
  modern-javascript-real-world-dev-part-02.1.zip
  modern-javascript-real-world-dev-part-03.1.zip
  modern-javascript-real-world-dev-part-04.1.zip
  unreal-tournament-2003-2004-part-01.1.zip
  unreal-tournament-2003-2004-part-02.1.zip
  unreal-tournament-2003-2004-part-03.1.zip

However, the new torrent that they posted does indeed include the two files missing from the Reddit torrent (which were also giving 404 when they originally realeased the files a week ago):

  xna-volume-2-part-01.zip
  xna-volume-3-part-01.zip

I am currently verifying the new torrent, but I have to leave any minute now so I don't have time to see what the result is until I get back but I think probably the new torrent they posted is going to verify correctly. We will see.

Edit: The new one is already reporting some files fail to verify as the first one did.

For reference, in this comment I am talking about the torrent file 3dbuzz-2020-01-13.torrent from the 3dbuzz website with SHA256 hash sum:

  e3adc900ff7d8bcb286119a059f216ea57a37096e84488c737f0db5b8e8eaeb5  3dbuzz-2020-01-13.torrent

Hm. Now the link to their new torrent leads me to 404..

The link currently posted on their website is https://www.3dbuzz.com/3dbuzz-2020-01-13

It looks like the link should have been https://www.3dbuzz.com/3dbuzz-2020-01-13.torrent

So it does.

For reference, the 3dbuzz.torrent file that I was talking about above that failed to verify some of the files has the following SHA256 hash sum:

  346306376c94abbb140ff89b76c016eca1c2d6346b822266c2918bf50fcd45f5  3dbuzz.torrent

In the meanwhile between then and now, I also wrote out the following about which files were failing to verify. This additional information is largely useless now that they have switched to what I assume is a good torrent. But just in case someone downloaded the bad torrent (bad in the sense that it fails to verify for some of the files), I will post that information here anyway and then maybe someone will find this and learn that they should download a different torrent than the one that they used originally instead.

In particular, these are the files that failed to verify in the 3dbuzz.torrent file that 3dbuzz was initially hosting on its website:

  3rd-person-character-system-part-03.zip      (verification failed at 85.71% of  24.6 MB)
  ai-programming-behavior-systems-part-01.zip  (verification failed at 98.92% of  75.4 MB)
  houdini-character-rigging-2-part-01.zip      (verification failed at 99.45% of 291.2 MB)
  houdini-director-volume-ii-part-01.zip       (verification failed at 99.63% of 420.5 MB)
  legacy-series-maya-part-01.zip               (verification failed at 99.93% of 528.1 MB)
  legacy-series-maya-part-02.zip               (verification failed at  0.00% of     4 KB)
  mastering-3dsmax-dragon-birthday-part-01.zip (verification failed at 99.33% of 565.5 MB)
  mastering-maya-when-mechs-attack-part-04.zip (verification failed at 99.00% of 384.4 MB)
  mathematics-algebra-part-01.zip              (verification failed at 99.76% of 230.9 MB)
  mathematics-part-01.zip                      (verification failed at 98.96% of 263.1 MB)
  mathematics-trigonometry-part-01.zip         (verification failed at 97.37% of 136.3 MB)
  modern-javascript--part-01.zip               (verification failed at 99.51% of 536.8 MB)
  modern-javascript--part-02.zip               (verification failed at  0.00% of     2 KB)
  modern-javascript-real-world-dev-part-01.zip (verification failed at 99.43% of 556.8 MB)
  modern-javascript-real-world-dev-part-02.zip (verification failed at 99.56% of 564.5 MB)
  modern-javascript-real-world-dev-part-03.zip (verification failed at 99.04% of 559   MB)
  modern-javascript-real-world-dev-part-04.zip (verification failed at 37.85% of   5.6 MB)
  unreal-development-kit-part-15.zip           (verification failed at 99.44% of 357.6 MB)
  unreal-tournament-2003-2004-part-01.zip      (verification failed at 99.17% of 528.7 MB)
  unreal-tournament-2003-2004-part-02.zip      (verification failed at 99.69% of 546.9 MB)
  unreal-tournament-2003-2004-part-03.zip      (verification failed at 98.85% of 322   MB)

The fact that all of these failed to verify in their last few MB of data has me inclined to believe that the issue was with the checksums in the torrent file itself. In practice this likely means that all clients that try to download the whole of that torrent will never finish downloading everything 100% because the verification will always fail for them too. Can anyone confirm or deny that this is the case if they tried to download that torrent?

> The peer distributing a data file treats the file as a number of identically sized pieces, usually with byte sizes of a power of 2, and typically between 32 kB and 16 MB each. The peer creates a hash for each piece, using the SHA-1 hash function, and records it in the torrent file.

Additionally, there are some duplicate files in that same 3dbuzz.torrent file:

  ai-programming-behavior-systems-part-01.1.zip
  houdini-director-volume-ii-part-01.1.zip
  mathematics-algebra-part-01.1.zip

> Most files listed below are available on this torrent: 3dbuzz.torrent. Some files are currently missing.

Looks like either the torrent itself, or the set of files the torrent was created from is corrupt, or containing different versions of some of the zip files, because the torrent does not completely verify against the zip files that 3dbuzz originally released to the public on their website a week ago.

Someone on Reddit made a torrent too, and the first torrent that person made had some issues too but then that person made a new, fixed torrent that verifies correctly against all of the zip files that were originially released to the public by 3dbuzz.

Here is a link to the torrent made by the person on Reddit, that verifies correctly for all of the files: https://drive.google.com/uc?export=download&id=1bljXeR1xv9Tp...
