Das Problem damit beschreibt das Berliner Weizenbaum-Institut für Digitalisierungsforschung: »Der Begriff ›digitale Souveränität‹ ist aus dem politischen Diskurs nicht mehr wegzudenken. Man ist sich über Parteigrenzen hinweg einig: Digital souverän sein, das ist erstrebenswert und wichtig. Dabei bleibt aber unklar, was es eigentlich genau bedeutet, digital souverän zu sein und wie man diesen wünschenswerten Zustand erreicht.«

Die Coolen Zonen bieten:

eine Ruhezone zum Entspannen
eine Zone für Austausch (Plausch, Spiele, Zeitschriften etc.)
kalte Getränke
(meistens) WLAN

his snippet should do it. If you are denying you may want to do this in the recipient ACL after you accept postmaster and abuse addresses. Watch which servers you reject, as some legitimate senders (airlines, banks, governments) have broken rDNS on their automated senders.

Verify reverse DNS lookup of the sender's host.

deny
message Reverse DNS verification failed
!verify = reverse_host_lookup
!hosts = ${if exists{CONFDIR/local_broken_dns_whitelist}\
{CONFDIR/local_broken_dns_whitelist} {}}

I find a lot of spambots give up quickly if they don't get a connection banner quickly enough. Including the following in a connect ACL may help. Disabling pipelining catches a number of spambots that don't behave well. If the delay is too long (over 30s) some legitimate servers will also give up.

Verify reverse DNS lookup of the sender's host.

Disable piplining and delay on failure.

warn
!hosts = ${if exists{CONFDIR/local_broken_dns_whitelist}\
{CONFDIR/local_broken_dns_whitelist} {}}
!verify = reverse_host_lookup
control = no_pipelining
delay = 10s

Technisch unterstützt DNS4EU Standards wie DNS over HTTPS und DNS over TLS. Die Server sind strategisch über die EU verteilt, was für schnelle Antwortzeiten sorgen soll. Ein besonderes Augenmerk liegt auf dem Datenschutz: Die IP-Adressen der Nutzer werden vor der Protokollierung vollständig anonymisiert, was die DSGVO-Konformität gewährleisten soll. Aus früheren Berichten weiß ich, dass ein EU-DNS-Dienst allerdings auch für Argwohn sorgt.

The very short version: It has now become clear that European governments can no longer rely on American clouds, and that we lack good and comprehensive alternatives. Market forces have failed to deliver a truly European cloud, and businesses won’t naturally buy as yet unproven cloud services, even when adorned with a beautiful European 🇪🇺 flag, so for now nothing will happen.

OK, if you have lots of Twitter embeds in your website, I've written an easy(ish) way to replace them with static images & alt text.

https://github.com/edent/Tweet2Img

Run:
python tweet2img.py 1234

And you'll get a ready-to-paste piece of HTML with a data-encoded image.

<a href="https:/ /twitter.com/edent/status/123"><img src="data:image/webp;base64,Ukl..." width="550" height="439" alt="text from tweet."/></a>

It also saves the WebP and alt text if you need them.

Let’s say I want to keep the latest version of each file as they are replaced or removed; essentially I want a “trash can”-like behavior. For this, I create the following script and store it as /Users/jb/bin/onlylatest.sh (i.e. the bin directory in my home directory):

The tools I used and will describe are:

VPS – in this case, I used a basic Hetzner Cloud VPS, but any provider that provides IPv6 connectivity will do – if you want IPv6, of course.
FreeBSD – a versatile, stable, and secure operating system.
Wireguard – lightweight, secure, and at the same time, not very “chatty,” so it is also gentle on mobile device batteries. When there is no traffic, it simply does not transmit/receive anything. Well supported by all major desktop and server operating systems as well as Android and iOS devices.
Unbound – can make DNS queries directly to root servers, not through forwarders. It also allows you to insert block-lists and have a result similar to that of Pi-Hole (i.e., ad-blocking).
SpamHaus lists – to immediately stop connections to and from users on blacklists.

Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It has built-in support for several families of weighting models and also supports a rich set of boolean query operators.

If you're after a packaged search engine for your website, you should take a look at Omega: an application we supply built upon Xapian. Unlike most other website search solutions, Xapian's versatility allows you to extend Omega to meet your needs as they grow.

Da sich sehr viele Besucher auf dem #37c3 für meine #LED-Sterne interessiert haben die beim @c3pb am #Dodekaeder hingen, wollte ich hier noch mal schreiben, unter welchen Suchbegriff man die kleinen LED-Stäbe bei gängigen Händlern findet: "meteor shower cob led pcb".

Um daraus einen Stern zu machen benötigt es dann nur noch etwas Klingeldraht und Geduld beim Löten. Welcher IC da drauf ist kann man leider nicht erkennen, aber vielleicht baue ich irgendwann™ mal eine RGB-Variante von den Dingern.

The GRIZ Sextant is an expression of my love of 80s computers. But what computers exactly? There is a multitude of wild machines from the 80s to choose from but in the end, I ended up choosing a somewhat surprising choice as my design inspiration, the GRID Compass.

It is difficult to properly describe my fascination with 80s computers. As a child of the 90s I did not grow up with Commodore or Tandy machines and did not pick up a mouse and keyboard until the Windows 95 era. So why the obsession with machines for an era I was not alive to see?

For me personally, there are multiple reasons. First, as someone who works in engineering and product design, I am fascinated by the design effort that went into machines before the era of computer aided design. I do not know what I would do without Solidworks in my day-to-day engineering life so the thought of designing a complex piece of consumer electronics without CAD is both awe inspiring and horrifying. Second, like many in the Cyberdeck community I am drawn to the styling’s of 80s products.

Petrolicious on Youtube features a video about the Lamborghini Countach and claims it comes from a time ‘When Outrageous was Possible’. I think this same sentiment can be applied to the computers of the 1980s.

Das Haus der Digitalisierung in Tulln ist nun ein Jahr im Vollbetrieb, am Donnerstag ist Bilanz gezogen worden. Die erste Ausstellung verzeichnete mehr als 13.500 Besucher. 2024 stehen die Themen Künstliche Intelligenz (KI) und Cybersicherheit im Fokus.

It struck me to put this together when I saw how close in size the 7" touchscreen, battery cells, and crkbd folded vertically that I had sitting on my desk were. And I I needed a build that was actually functional for normal computer stuff, so this seemed like a good idea.
It turns out that this is a pretty functional setup. The 7" display is okay as long as I fullscreen stuff. Alt+F11 works with a lot of stuff so far. I've been able to use onshape cad in firefox. It's a little slow, but works as long as firefox doesn't have issues with gfx acceleration. Console stuff and web browsing are great!

In the first article of this series on using Ansible to configure a workstation, we set up a repository and configured a few basic things. In the second part, we automated Ansible to apply settings automatically when changes are made to our repository. In this third (and final) article, we'll use Ansible to configure GNOME desktop settings.

This configuration will work only on newer distributions (such as Ubuntu 18.04, which I'll use in my examples). Older versions of Ubuntu will not work, as they ship with a version of python-psutils that is too old for Ansible's dconf module to work properly. If you're using a newer version of your Linux distribution, you should have no issues.

I was looking for a small, lightweigt, affordable but powerful battery for portable ham radio use and decided to buy a Miady 12,8V 7,2Ah LiFePO4 battery.
