Tips

Just a quick note to remind myself how I fixed the problem installing VirtualBox 5.2.10 on a Mac laptop running 10.13.4. The installation seemed to go well until it reached the end and reported failing to install. I’ve had this issues for a few weeks already and Google for solution seems to have hit and missed until today. I finally found a solution posted here: https://github.com/docksal/docksal/issues/417. Basically, I need to go the System Preferences and tick the box to allow ‘System software from developer “Oracle America, Inc.” was block from loading’.

I just updated Ansible to version 2.5.0 tonight, and I came across this issue when I tried to run a playbook for an Ubuntu 16.04 machine: PLAY [Ansible Playbook for configuring odroid.***.com] *************************************************************************************** TASK [Gathering Facts] ***************************************************************************************************************************** fatal: [odroid.***.com]: FAILED! => {"changed": false, "cmd": "None -s system-product-name", "msg": "[Errno 2] No such file or directory: 'None'", "rc": 2} According to the issue #37911, the remote system doesn’t have the dmidecode package installed. This is true in my case, and it can be verified as the following: ...

At work, we want to backup an external disk that’s connected to the Mac machine using rsnapshot. In order to do that, the external drive needs to be mounted, and this happens when a user logs in to the Mac. The problem is that when nobody logs in, the external drive is not mounted and rsnapshot will fail. The fix should be easy if there is away to mount the external drive without a user logs in. It turns out that on OS X (tested on High Sierra) we can set a flag to have the external drives get mounted when the Mac boots up. ...

This laptop runs FreeBSD 12.0 current. The version of the installed Firefox is 59, which is pretty new isn’t it? Well, that’s not new or good enough to browse outlook.office365.com email. What happened is that, the Outlook web based email would just automatically switch to class Outlook web access. This problem is not unique to Outlook email, even some work related websites refuse to load correctly on Firefox running FreeBSD. ...

It’s another night with another FreeBSD problem. Well, I could just use Linux like Ubuntu or Void, but then things would just work. Where is the fun? 😉 So, I’ve been having problem with upgrading or installing new binary packages on a machine running FreeBSD 12.0 for a few days now. root@vansota:~ # pkg upgrade Updating FreeBSD repository catalogue...
