This means that I had a few years worth of activity data that I wanted to move from my Apple Health app to Garmin Connect.
However, that turned out to be not that straight-forward. Garmin only allows you to import GPX, FIT or Fitbit CSV files, not any Apple Health data.

While namespacing processes using cgroups creates very good boundaries between processes, the isolation is still not perfect.

For different reasons I am now migrating to gopass, a Go implementation of pass with a few additional features. I am using Homebrew to install gopass on my machine: brew install gopass. Theoretically, gopass should work out-of-the-box and is compatible with the old pass utility. So I was quite surprised to see an error message like this:
$ gopass github
Entry 'github' not found. Starting search...
Found exact match in 'github.com/simonkrenger'
gpg: decryption failed: No secret key
Error: failed to retrieve secret 'github.com/simonkrenger': Failed to decrypt
Strange. But decrypting the password file directly using PGP works fine:
$ gpg -d ~/.password-store/github.com/simonkrenger.gpg
[..]
If the above command using gpg does not work, check your keys using gpg --list-keys and gpg --list-secret-keys. Especially when migrating to GPG2, sometimes keys do not get imported into the new keyrings. In case you need to import the old keyring into the new format like so:
$ gpg --import ~/.gnupg/pubring.gpg
$ gpg --import ~/.gnupg/secring.gpg
But even after importing the keys, I still received gpg: decryption failed: No secret key. So after searching around I found that I need to set the GPG_TTY variable:
$ export GPG_TTY=$(tty)It seems that not setting the GPG_TTY environment variable leads to the error above. Which is quite misleading. After setting this environment variable (and adding it to the .bash_profile), gopass works as expected.
A user of the Tanuki Service Wrapper reminded me that Tanuki released version 3.5.36 of the Java Service Wrapper some time ago. So in this post, I can provide version 3.5.36 of the Java Service Wrapper for Windows x64.
If you have worked with remote Linux servers before, I am guessing you already encountered machines that just don’t want to reboot. This is typically due screwed-up network mounts or stuck processes, so the server will hang during shutdown. But it turns out that there are other ways to reboot a server.
One of these is the “Magic SysRq key“. To reboot a server using the SysRq trigger in the kernel, use the following two commands. First, enable the trigger:
echo 1 > /proc/sys/kernel/sysrqThen, reboot the server the magic way by typing
echo b > /proc/sysrq-triggerNote that this will reboot the server without unmounting or syncing the filesystems! There are also other options available via the SysRq trigger, some of them are listed in the Wikipedia article above.
So I started working with GitLab (self-hosted and gitlab.com), which led me to the CI/CD features of GitLab. When using GitLab, one can define a custom CI pipeline just by placing a .gitlab-ci.yml file in your project (just like the .travis.yml for GitHub). After each commit to the defined git branch, the pipeline is then executed.
Since I also work with Ansible playbooks a lot, I wanted to use ansible-lint to check my playbooks after each commit. In addition to that, I also added a syntax check using ansible-playbook [..] --syntax-check, as ansible-lint will not pick up all syntax errors.
So here is my .gitlab-ci.yml:
