“The very worst-case speculative scenario for Huawei-as-Chinese-Trojan-horse is infinitely better than the non-speculative, real ways in which the US has killswitched and bugged the world’s devices.” Cory Doctorow explains why responsible governments should have to accelerate their countries’ independence from US tech and not just Russian gas.

Configure nullmailer with a relay host
If you wish to receive status updates from your Debian or Ubuntu system, you need to install and configure a mail transfer agent (MTA). nullmailer is a relay-only forwarding MTA that can be used as an alternative to more complex MTAs, such as Exim, Sendmail or Postfix.
A relay host, also referred to as a smarthost, can be defined as an email server for outgoing mail that is being afforded a good reputation by its peers. In this example, we use Fastmail because email deliverability depends on a number of different factors.
Configuration of nullmailer with Email Service Providers (ESPs) other than Fastmail should be similar, given that all ESPs implement the Simple Mail Transfer Protocol (SMTP).
Step 1
Generate an app password
Log into your Fastmail account and set up a new app password for SMTP authentication.
Create an alias
Set up a dedicated Fastmail alias to receive incoming messages.
Step 2
Use copy and paste to enter the following commands. Be careful not to miss any punctuation.
Create the new directory /etc/nullmailer and the file /etc/nullmailer/adminaddr.
$ sudo mkdir /etc/nullmailer && sudo nano /etc/nullmailer/adminaddr
The Fastmail alias you created in Step 1 should be the only entry in /etc/nullmailer/adminaddr.
target.email@fastmail.com
Step 3
Install the required packages.
$ sudo apt-get install --yes nullmailer mailutils
Step 4
Enter the system mailname. If you are setting up on a home network, you should use home.arpa as the domain name.
Configuring nullmailer
Mailname of your system:
tux.home.arpa
Ok
Configuring the smarthost
Configure nullmailer to use the Fastmail SMTP server as a smarthost. Use your Fastmail username and the app password from Step 1.
Configuring nullmailer
Smarthosts:
smtp.fastmail.com smtp --port=587 --auth-login --starttls --user=linus.torvalds@fastmail.com --pass=password
Ok
Step 5
Test your configuration with the following command.
$ echo "Test mail from nullmailer on tux.home.arpa to the local root user and forwarded on to Fastmail" | mail -s "Test nullmailer" root
Check your inbox!
Step 6
You can reconfigure nullmailer at any time by issuing the following comand.
$ sudo dpkg-reconfigure nullmailer
Curate your own newspaper with RSS
“In a media landscape dominated by algorithmic feeds that aim to manipulate and extract, sometimes the most radical thing you can do is choose to read what you want, when you want, without anyone watching over your shoulder.”

Can passkeys replace passwords
“Passkeys and the WebAuthn specification were intended to make public key cryptography accessible to average users, rather than just the domain of the tech-savvy. If done right, they could seriously improve security on the Web.” @Drbruced summarises why passkeys are such a good idea in theory and explains where current implementations of the technology fall down in practice.
Viele gute Gründe für das Fediverse
“Die vor uns stehenden Umwälzungen der digitalen Transformation sind von historischer Dimension. Sie sind in ihrer Bedeutung vergleichbar mit den Veränderungen im Zeitalter der Aufklärung, die die Grundlage für die Menschenrechte und ein friedlich vereintes Europa legten.”
Mario Birkholz sieht die Hochschulen in der Pflicht, ihre digitale Kommunikation mit den Anfoderungen des demokratischen Gemeinwesens in Einklang zu bringen.
A hacker’s perspective: social media account takeover prevention guide

European Comission gives EU-US data transfers third round at CJEU
“This third attempt to pass largely the same unlawful decision also raises questions as to the larger role of the European Commission being the guardian of the EU treaties. Instead of upholding the ‘rule of law’ the Commission simply passes an invalid decision over and over again, despite clear rulings by the CJEU.” By agreeing the Data Privacy Framework with the US, the European Commission likely prioritised diplomatic and business interests over the rights of Europeans.
Nichts zu verbergen? Ein moderner Mythos und 12 Argumente dagegen
“Aber der Satz und seine Verbreitung schaden viel mehr der Gesellschaft und anderen Menschen, als jenen, die ihn aussprechen. Deshalb sind mir die sozial orientierten Antworten darauf am liebsten: Weil man Menschen damit stigmatisiert, sie unsolidarisch behandelt, ihre Diskriminierungserfahrungen negiert, und weil es Demokratie und Widerstand untergräbt.” @reticuleena legt offen, wie wir unsere Vertrauenswürdigkeit aufs Spiel setzen.
