Run powershell on macOS

I often need to run a remote session in powershell e.g. managing online exchange. This may sound crazy but you can run powershell on a Mac. Before I discovered this I always had to first remote desktop in to a Windows Machine or fire up a VM to be able to start the remote session. If you google a bit you will find lots of instructions to install powershell on Mac. Read more

Using Windows Powershell for System Administration

I am more of a Unix guy but I get to administer more and more Microsoft systems as time goes by. Back in the day Windows had very limited commandline options to manage systems. It often felt that you were working on a car with the bonnet welded shut. Luckily things changed when Powershell arrived on the scene. Powershell is a bit counter intuitive for someone that used Unix shells for 30 years but it is very powerful and you can do a lot with it. Read more

Never check in your luggage if you can at all avoid it.

If you travel by air try to have hand luggage only. Even the best airlines lose luggage or delay your luggage for various reasons. The airline is also dependent on the Airport ground staff to make sure passenger luggage is handled properly. You can easily travel for up to three weeks with only hand luggage. My advise: Take a third of the stuff you think you will need, and three times the money you think you will need. Read more

How to create a bootable installer for macOS

There is a new version of macOS out (at the time of writing 10.14 Mojave) and you want to upgrade. For the past few upgrades and this one Apple provided the update via the App store. This is all fine and well if you have a good unmetered(uncapped) internet connection to download the +- 5Gbyte installer. The big catch with the installer is if you follow the default install procedure the installer deletes itself after the install. Read more

Outlook is rubbish!

Microsoft Outlook especially older versions is junk, but you probably knew that already. For some reason Outlook often sends out a message with incorrect syntax e.g. “[email protected]”. Mail servers like postfix will reject these messages but Outlook will not warn its user that there is a problem. Instead it will keep the message in the outbox and continously retry sending. If you are a postfix admin you can strip the apostrophes with a command filter. Read more

Creative Soap forms

I previously posted a tip about making your own soap. If you do make your own soap you will often have a problem with suitable forms for the soap. If you want to make round “bars” of soap instead of square or retangular, life often becomes difficult. You will find lots of ideas by searching for soap forms but the best I found was to use a pringles can. Read more

Change vim 8.0 .vimrc behaviour back to sanity

When a user doesn’t have a /.vimrc file in vim 8.0 (and possibly later) vim loads the default configuration file after the systemwide vimrc file created by the system administrator. This overides any settings the system administrator made. This is of course totally unexpected and frustrating especially when you upgrade from earlier versions. Some may even call it insane and it is definitely not expected behaviour. Anyway below is a way to prevent that from happening. Read more
