Encryption

There’s been a lot of discussion lately (again) on the need for encrypted Email or Messaging, and the pros and cons of various services, from WhatsApp to Telegram, from RCS to SMS.

I am not fully on the post-privacy bandwagon, but for sure people are aware that by using a third party service for Email or Messaging their messages can be read, aren’t they? We don’t call root super-user for no reason.

In the last century the Network Working Group wrote in RFC 1855 “Netiquette Guidelines”

2.1.1 For mail:

Unless you are using an encryption device (hardware or software), you should assume that mail on the Internet is not secure.  Never put in a mail message anything you would not put on a postcard.

That’s today as true as it was then – unless you own both sides of the encryption, don’t send anything through the Aether that you don’t want other people to see!

Climate Pledge

Here are my five pledges to support climate action in 2019:

  • I will not renew the contract for our family car
  • I will stop flying for vacation, and minimize air travel for business
  • I will avoid using single-use plastic items
  • I will buy fair-trade and carbon-neutral wherever possible
  • I will go back to a vegetarian life once I have reached my target weight

What do you plan to do?

(#SoKoFuture)

Fridays For Future Summer Congress

Over the last five days I had the honor and pleasure to be able to support the Fridays for Future summer congress #SoKoFuture in Dortmund as a volunteer.

And was I in for a treat!

I have never seen so many people being so kind to each other, working all day diligently and earnestly on the most pressing issues of our time, and coming up with ideas on how to save our planet – people, especially politicians, who belittle these efforts should be ashamed.

The center-right paper “Die Welt” called the congress the Political Woodstock – I think that’s quite a fitting description.

After spending this time with all these young people I know for sure that a different world will be possible.

The Fridays deserve our full support!

Freelance Rancher

After a brief stint at a small consultancy in Cologne I decided to go back to working as a freelance IT architect and consultant, with my favorite open source cloud projects, Rancher and Kubernetes, and everything else cloud native. I have also submitted a couple of papers to regional conferences.

From August onwards I’ll then have two more years at University, and during that time I’ll need to figure out whether I should be starting my own business, continue going solo, or try to find full-time employment again. Main goal: Get my kids through college. And enjoy my work.

On that note: I’ve passed all exams so far and am happy with the results!

Android Pie Backup Now grayed out

This week I migrated my phone from a Nokia 8 to a Nokia 9 PureView, for the impressive built-in camera.

After completing the migration I found that I was unable to perform a backup – the Backup Now button was grayed out and all items were in “Waiting to backup” (except for Contacts and Photos, which operate independently).  Google to the rescue!

I found many good posts, some recommending to temporarily disable Screen Lock. That worked – I then had a valid backup in Google Drive.

After I re-enabled the screen lock, though, the button became grayed out again – back to Google.

Several people recommended setting up Smart Lock, so that the phone unlocks itself, for example when you’re at home.

Enabled Smart Lock, no change, button still grayed out. Bummer.

This time though I decided to give it a couple of days – a good idea, since there seems to be a timer involved, too.

Issue is now solved, the phone performs automatic backups, if

  • it’s at home and automatically unlocked, and
  • the last backup is more than a day old

Good enough for me. But I will regularly check in Drive from now on …

Server housekeeping

From time to time it does make sense to clean your computer systems, literally speaking.

Especially if you run them in a domestic or office setting, any system with a fan will collect dust. A lot of dust.

Nothing a can of pressurized air, a hoover and a set of baby wipes can’t fix though .

Did anyone say weekend?

Spiderman: Far From Home

What a ride – first, Spiderman: Into the Spider-Verse, probably the best animated movie this year with a lot of fresh ideas, then, Avengers: Endgame where Peter took the mantle from Tony Stark. And now, Spiderman: Far from Home

Far from Home is a great reboot of the Spiderman universe, portraying a cool super hero fit for the 21st century; at the same time it also showed a lot of continuity and references to past Marvel movies for fans, old and new alike

Highly recommended – go watch it, but stay until after the credits!

Paintball

There’s always a first time for things – for us it was the first time for playing paintball this Friday.

We went to Paintball Revolution in Ennepetal, as they offer markers for 14- to 18-year-olds.

The staff on site was great, plenty of playing fields and game ideas, we played for hours – highly recommended!

Sherwood

Through the original family option of Google Play Music All Access we were migrated to YouTube Premium (YouTube Red in some geographies), and with this we also got access to YouTube Originals, which includes a variety of high-quality mini series.

One of these is Sherwood – loosely based on the legend of Robin Hood, the series is set in a world where the climate catastrophe has already happened and most of the world is flooded, it chronicles the adventure of Robin and her friends in their fight for justice and equality against the Sheriff of the upper city.

Very relatable characters, good storytelling and great animation make this a fun series to watch – highly recommended!
