Happlink / PlugUp died, but you can still use their U2F USB key

Posted by jpluimers on 2020/01/31

Nothing lasts, so the company behind the U2F key on the right is long gone, but their site is archived in and the WayBack machine. Since the U2F protocol is open, you can still set up the device and use it. Here is how for your Google account (for instance with GMail), it works in a similar way for other providers:

Archived links:

Some of their videos are also still online (embedded links at the bottom of the post):

U2F (or Universal 2nd Factor – Wikipedia) has an open protocol by FIDO Alliance – Wikipedia. More on that in these links below.

One final odd note:

The FIDO alliance still listed Happlink on their web-site when I wrote this blog post.

It used to be at this address: Happlink, 4 rue Jehan Le Povrmoyne, 76240 Le Mesnil-Esnard, France

When storing huge files under NTFS compression, ensure you have twice the disk space

Posted by jpluimers on 2020/01/31

When copying over a 400 gigabyte file over the network to an NTFS compressed folder on a drive with having 600 gigabytes free space, the volume became full after copying ~350 gigabytes.

What I learned is that compressing huge files for later read-only access is fine, but you need about twice the disk space while the copy operation is in progress.

For non-compressed files you can go without this extra reservation.

Background information:

Note there are also issues with NTFS compression and de-duplication. I’m not sure about sparse files. Be careful when you try to compress the system drive where your Windows OS lives on:

Sunsetting Mercurial support in Bitbucket – Bitbucket

Posted by jpluimers on 2020/01/30

February 1st, the start commences of Sunsetting Mercurial support in Bitbucket – Bitbucket [WayBack]. Starting June 1st, only git is supported by Bitbucket, despite them having started with and focused mainly Mercurial at first.

Here are the major dates of the sunset:

  • February 1, 2020: users will no longer be able to create new Mercurial repositories
  • June 1, 2020: users will not be able to use Mercurial features in Bitbucket or via its API and all Mercurial repositories will be removed.

All current Mercurial functionality in Bitbucket will be available through May 31, 2020.

So by now you should have started migrating from Mercurial to git, probably away from BitBucket.
