I had to rebuild my CUPS server and the new address had dashes instead of underscores, but otherwise was identical. I had fun adding my CUPS printer to Windows 11 this evening. I was unable to rename the network address like I was able to do on my machine. My old notes were useless. I was able to automatically find and add the printer, but that did not work. Tweaking settings just resulted in more errors. I removed the new printer entry, added it again just like I did before, and it worked.

There are lots of plotter projects out there such as https://www.thingiverse.com/thing:4796222 To adapt it to a crayon, you would likely need some sort of additional weight or slow extruder as the crayon would wear down faster than a pen or marker. For small drawings, the additional edge-case would probably not matter.

I keep a pair of HEAROS High Fidelity Ear Plugs with me if I potentially will end up at a live music event. They are earplugs with a tiny air hole such that the sound should not be distorted much and mostly just turned down. The only issue/perk is that it is extra difficult to hear people that are right beside you.

My favorite type of email spam is the Illuminati scam where someone is invited to join the elite at a financial price. It is dark hilarious that a similar group actually exists exactly matching that format with reputable senders.

There are many C2 domains in these links. Has anyone compiled a list of these domains into a pi-hole compatible list?

JShelter 0.23 is out! Are you concerned about #BrowserGate and fingerprinting? When you are browsing, you need extra protection. The #JShelter extension should be part of that protection. Read about the changes here: https://jshelter.org/versions/#023

People are upset at Google again. Of course Google added Gemini to Chrome. That should not surprise anyone. Why are you still using Chrome in 2026? Use Firefox and the good version of uBlock Origin.

Darknet Diaries is a great podcast. The two-part episodes 99 and 100 are probably the peak, but it is the only podcast that I have listened to every episode.

The latest episode of #DarknetDiaries about piracy boxes with malware is really good and worth a listen. https://darknetdiaries.com/episode/172/ As a sysadmin, I've been defending my networks from botnets using these "residential proxies" for years.

A member of my family was having difficulty printing out some images for a school project. It seemed like all of the Google Image search results were watermarked and required payment.
I want to highlight this CC0 image search tool that has been a very useful resource for me: https://free-images.com/

#GitHub users have until April 24 to opt-out of unnecessary #Copilot training data.
Story: https://github.blog/news-insights/company-news/updates-to-github-copilot-interaction-data-usage-policy/
Direct link to settings: https://github.com/settings/copilot/features
I would recommend going through and disabling all of the options on the page that you are allowed to disable.

Fallout: New Vegas is a magnificent example of a computer RPG. It is rough around the edges and incomplete, but it has so many memorable scenes in it along with an odd collection of distinct factions. It is normal for it to take about 10 tries before it boots kind of like starting an old lawnmower. Max out luck and don't try to take the shortcut.

Arch uses a radically different philosophy for package maintenance. Instead of having an army of software maintainers backporting security patches to a fixed version for years, they let upstream do their thing for the most part unless something big breaks. The benefit is that you get updates packages faster and get to participate in the active development of the software that you use. The drawback is that things break every now and then.

When I get to pick, I usually go with Debian, Trisquel, or Arch.

Where did this English version come from? I found the article. https://niboe.info/whatsapp-telegram-signal-privacidad/
For completion, here is the 2021 article I based that slide of mine on:
https://fsf.org.in/article/better-than-whatsapp/ I used slightly different language.

I know I am in a minority, but I do not trust #Signal service. I talked about Signal in comparison to several other messaging platforms in my HOPE 2022 talk. The content is still relevant and very little has changed. Starts around the 28:45 mark.

Not you too! E2EE without the ability to manage your own keys and verify the mechanisms of encryption means that Apple can introduce more ghost keys behind the scenes allowing themselves and others to be included in who can decrypt the information.
Then there is the whole notifications issue where Apple and Google were leaking that which should be local. https://www.reuters.com/technology/cybersecurity/governments-spying-apple-google-users-through-push-notifications-us-senator-2023-12-06/
I don't trust Apple.

Sadly many people believe that Apple is secure. That is what they keep saying. Even EFF repeat their ads.
