Tipp: TLS 1.1-Verbindung bei PowerShell akzeptieren

PowerShell-Scripte verwenden unter Umständen nur aktuelle TLS-Protokolle, die zwar sicherer sind, aber nicht von jedem Server unterstützt werden – rs gibt bis heute Server, die nur mit TLS 1.1 kommunizieren. Das führt dann zu folgenden Fehlermeldungen (und zum Abbruch des Scripts):

[...] Die Anfrage wurde abgebrochen: Es konnte kein geschützter SSL/TLS-Kanal erstellt werden. [...]

Der Workaround ist zum Glück recht simpel: Auf der Kommandozeile sollte vor dem Aufruf eines derartiges Scripts dieses Statement ausgeführt werden:

$AllProtocols = [System.Net.SecurityProtocolType]'Tls11,Tls12'
>> [System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols

Dies kann alternativ auch in das Script direkt eingefügt werden. Anschließend funktioniert der Abruf von der geschützten Ressource.

Lesetipp: Targeted Advertising is ruining the Internet and Breaking the World

Ich habe ja kürzlich bekannt gegeben, dass ich mich komplett von Facebook zurückziehen werde. Ebenfalls bin ich von Android auf die iOS-Plattform umgestiegen. In der Firma werden wir Macs einsetzen.

Das alles hat seine Ursachen in der Datensammelwut von Google und Facebook, in der kompletten Ignoranz in Bezug auf Datenschutz und Privatsphäre und im Versuch, Werbung zu verkaufen, die möglichst maßgeschneidert ist.

Die Folgen dieser Dinge sind dabei noch viel gravierender, als sie es offensichtlich bereits eh sind.

Hier ist nochmal ein Lesetipp, der ausführlich das Problem erklärt: https://motherboard.vice.com/en_us/article/xwjden/targeted-advertising-is-ruining-the-internet-and-breaking-the-world.

Lesen, ggf. mit Google Translate (sic!) oder den Text in Deepl kopieren und dann übersetzen, nachdenken und dann handeln!

Ninety Minutes to #Berlin

lrm_export_20180706_2024397848493981448649671.jpg

250km/h. Don’t try this at home.

While heading back home from Frankfurt to Berlin, I had to change trains in Hannover. From there to Berlin the distance is quite exactly 300km. Have you ever tried doing this on the infamous A2 Autobahn? It will usually take around three to four hours, often even more.

In comparison, the ICE train I’m currently in will do the same distance in less than ninety minutes.

Ninety. Minutes. From Hannover. To Berlin.

And yes: Spandau is not Berlin. But from Hannover to Spandau, it will only take around 75 minutes.

I have an open slot at 6.30am…

This has been said just seconds ago in a meeting I am currently attending. We’re not talking about freelancers here, but a pseudo-agile project with an enterprise customer.

See the problem?

Agility is not about having meetings cluttered all over the day, but efficiency. If your calendar is blocked so extensively by meetings, then perhaps, perhaps something is wrong.

Pro-Tipp: Change it. Cancel the unnecessary or unproductive meetings. Only attend meetings making any sense. Do not attend meetings for the sake of attending them.

Pro-Tipp 2: Participating in Scrum? Only do the scrum-stuff: Daily, Retrospective, Review, Plannings and perhaps Estimation meetings. All the other meetings should be obsolete if you communicate transparently. They should be attended by some POs or Architects, but not by every other person participating in the team.

Pro-Tipp 3: Participating in Kanban? Only do the minimally required stuff: Daily, Jour-Fixes or Reviews, Plannings. Work with your kanban board. All the other meetings should be obsolete if you communicate transparently. They should be attended by some POs or Architects, but not by every other person participating in the team.

(Hmmm, that’s pretty much the same content in Tipps 2 and 3. Coincidence? I don’t think so…)

Pro-Tipp 4: Get your stuff done!

Pro-Tipp 5: Get. Your. Stuff. Done!

#Tipp: How to bring wireless charging to any mobile device

Many, if not the most, mobile devices do not provide wireless charging capabilities. This is annoying, since it is so convenient to charge without plugging in any cable.

The solution is very simple: Just plug in a wireless charging receiver into the charging port of your device. Yes, it looks a little odd and you’ll need a case to properly ensure the receiver’s position, but you’ll have the comfort of wireless charging immediately and without extensive cost, since receivers start at around 10,– Euro.
