Did you know that you can adjust the appearance of the search page with url parameters?

Here it is described how:

Currently I fail to successfully install synapse (matrix home server) behind a reverse proxy.

Running matrix on the front server is not an option, since is not the most important service that has to run on that domain/server.

Is this possible? Has anybody suceeded doing such a setup?

All I find online are questions and frustrated users, who probably gave up - can someone help here?

Did anyone install synapse (matrix homeserver) successfully behind a reverse proxy using apache2? If so, I would be thankful for a config example.

Hat jemand erfolgreich Synapse (Matrix Homeserver) erfolgreich hinter einem Reverse Proxy mit Apache2 installiert? Wenn ja, wäre ich für ein Konfigurationsbeispiel dankbar.

40% der weltweiten! Anfragen über Name, Anschrift usw. bei #iPhones & Co stammen aus Deuschland.

Wann wurde es Mode, Server-Anwendungen nur noch als File auszuliefern? Ich will das nicht. Und im Falle meines Servers kann ich das auch nicht.

Prinzip der Datenbanken

Postfix kann mit einfachen Textlisten nicht umgehen. Der Grund hierfür ist, dass Postfix auf einen schnellen Zugriff durch Indexierung angewiesen ist, um vor allem Installationen mit sehr vielen Usern effektiv bedienen zu können.

What, acutually, is Nextcloud Hub? Is this the 18.0 version, which is not stable yet?

Does "built in office" mean that will come with a preinstalled package?

Will it work on ARM architecture, then?

I would be happy to get some information. I am running a 17.0.2 instance and I don't see any of the features yet.

Wozu Dovecot?

Während sich Postfix, das wir im ersten Teil des Tutorials installiert haben, um den Mailversand und Empfang mit der Außenwelt kümmert, ist Dovecot das Programm, das die lokalen Postfächer verwaltet, zum Mailversand und Empfang mit Pos

In den letzten Wochen habe ich mich mit einer Installation eines Mailservers (Postfix/Dovecot) gequält.

Daraus ist bei mir die Erkenntnis gewachsen, dass es an einem Tutorial fehlt, das nicht einfach Copy&Paste von Konfigurationsdateien ist, sondern wirklich *erklärt*, was man da macht.

Ich habe mir daher vorgenommen, in den nächsten Tagen ein mehrteiliges Tutorial zum Aufsetzen eines Mailservers zu veröffentlichen.

Ihr könnt gespannt sein. 🙂

RaspberryPi Nextcloud Backup


Auf dem Raspberry Pi ist Nextcloud installiert. Wie sichert man Nextcloud?

Orte, die zu sichern sind

Insgesamt besteht eine Nextcloud-Installation aus drei Teilen:

Wann ist eigentich ? Ein alter -nerd wie ich tippt dann mal ncal -e in die Konsole. Nicht zu verwechseln mit ncal -o . Da ist orthodoxes Ostern.

So I was recently asked why I prefer to use free and open source software over more conventional and popular proprietary software and services.

A few years ago I was an avid Google user. I was deeply embedded in the Google ecosystem and used their products everywhere. I used Gmail for email, Google Calendar and Contacts for PIM, YouTube for entertainment, Google Newsstand for news, Android for mobile, and Chrome as my web browser.

I would upload all of my family photos to Google Photos and all of my personal documents to Google Drive (which were all in Google Docs format). I used Google Domains to register my domain names for websites where I would keep track of my users using Google Analytics and monetize them using Google AdSense.

I used Google Hangouts (one of Google’s previous messaging plays) to communicate with friends and family and Google Wallet (with debit card) to buy things online and in-store.

My home is covered with Google Homes (1 in my office, 1 in my bedroom, 1 in the main living area) which I would use to play music on my Google Play Music subscription and podcasts from Google Podcasts.

I have easily invested thousands of dollars into my Google account to buy movies, TV shows, apps, and Google hardware devices. This was truly the Google life.

Then one day, I received an email from Google that changed everything.

“Your account has been suspended”

Just the thing you want to wake up to in the morning. An email from Google saying that your account has been suspended due to a perceived Terms of Use violation. No prior warning. No appeals process. No number to call. Trying to sign in to your Google account yields an error and all of your connected devices are signed out. All of your Google data, your photos, emails, contacts, calendars, purchased movies and TV shows. All gone.

I nearly had a heart attack, until I saw that the Google account that had been suspended was in fact not my main personal Google account, but a throwaway Gmail account that I created years prior for a project. I hadn’t touched the other account since creation and forgot it existed. Apparently my personal Gmail was listed as the recovery address for the throwaway account and that’s why I received the termination email.

Although I was able to breathe a sigh of relief this time, the email was wake up call. I was forced to critically reevaluate my dependence on a single company for all the tech products and services in my life.

I found myself to be a frog in a heating pot of water and I made the decision that I was going to jump out.

Leaving Google

Today there are plenty of lists on the internet providing alternatives to Google services such as this and this. Although the “DeGoogle” movement was still in its infancy when I was making the move.

The first Google service I decided to drop was Gmail, the heart of my online identity. I migrated to Fastmail with my own domain in case I needed to move again (hint: glad I did, now I self host my email). Fastmail also provided calendar and contacts solutions so that took care of leaving Google Calendar and Contacts.

Here are some other alternatives that I moved to:

Gmail → Fastmail → Self-hosted (via Cloudron)
Google Contacts → FastmailNextcloud Contacts
Google Calendar → FastmailNextcloud Calendar
Google Search → BingDuckDuckGo
Google Maps → Bing MapsOpenStreetMaps and OsmAnd
Google Analytics → Matomo Analytics
Google Drive → Nextcloud Files
Google Photos → Nextcloud Files/Gallery
Google Docs → Collabora Office (Nextcloud integration) and LibreOffice
Google Play Music → Spotify / PlexSpotify / Jellyfin
Google Play Movies/TV → PlexJellyfin
Google Play Audiobooks/Books → Audible/Kindle
Google Play Store (apps) → F-Droid / Aurora Store
Google Android → Lineage OSUbuntu Touch on PinePhone (coming soon?)
Google’s Android Apps → Simple Mobile Tools
Google Chrome → Mozilla Firefox
Google Domains → Hover
Google Hangouts → Matrix and Nextcloud Talk
Google Allo → Signal
Google Podcasts → PocketCastsAntennaPod
Google Newsstand → RSS
Google Wallet → PayPal and Cash App
Google Voice →Ting Mobile

Migrating away from Google was not a fast or easy process. It took years to get where I am now and there are still several Google services that I depend on: YouTube and Google Home.

Eventually, my Google Home’s will grow old and become unsupported at which point hopefully the Mycroft devices have matured and become available for purchase. YouTube may never be replaced (although I do hope for projects like PeerTube to succeed) but I find the compromise of using only one or two Google services to be acceptable.

At this point losing my Google account due to a mistake in their machine learning would largely be inconsequential and my focus has shifted to leaving Amazon which I use for most of my shopping and cloud services.

The reason that I moved to mostly FOSS applications is that it seems to be the only software ecosystem where everything works seamlessly together and I don’t have to cede control to any single company. Alternatively I could have simply split my service usage up evenly across Google, Microsoft, Amazon, and Apple but I don’t feel that they would have worked as nicely together.

Overall I’m very happy with the open source ecosystem. I use Ubuntu with KDE on all of my computers and Android (no GApps) on my mobile phone. I’ve ordered the PinePhone “Brave Heart” and hope to one day be able to use it or one of its successors as a daily driver with Ubuntu Touch or Plasma Mobile.

I don’t want to give the impression that I exclusively use open source software either, I do use a number of proprietary apps including: Sublime Text, Typora, and Cloudron.
