Monal IM: Funding campaign: Mac Mini for faster Monal development

Update 15.02.2022 Thank you very much. We reached our target of 1000€ within less than a week. We will order our new Mac mini tonight. Stay tuned for a big development blog post.

To improve the development situation it would be of advantage to have a physical build server for the developers.

PEP 683: Immortal Objects, Using a Fixed Refcount
Under this proposal, any object may be marked as immortal.
“Immortal” means the object will never be cleaned up (at least until
runtime finalization). Specifically, the refcount for an immortal
object is set to a sentinel value, and that refcount is never changed
by Py_INCREF(), Py_DECREF(), or Py_SET_REFCNT().
For immortal containers, the PyGC_Head is never
changed by the garbage collector. ⌘ Read more

The Impacts of an Insecure Software Supply Chain
Today, software regularly integrates open-source code from third-party sources into applications. While this practice empowers developers to create more capable software in a shorter time frame, it brings with it the risk of introducing inadequately vetted code. How aware are we of the security of our open-source code? Most of us use pip or npm […]

First impressions of my new printer
I recently bought a new printer: the Xerox B225. I discovered it by chance (while looking for a good printer) as a reduced return in an online store. Someone must have just tried it out briefly and sent it back. I’m happy! ⌘ Read more

Pluriverse instead of Metaverse
This artifact is a follow-up to A Declaration of the Interdependence of Cyberspace, where we introduce the term “pluriverse” and apply it to cyberspace. After the creation of the Declaration, its core stewards were joined by others who were moved by the vision of that artifact, and together, formed Verses. We are a multidisciplinary arts and research collective co-imagining, practicing, and building a commonly-held digital future. ⌘ Read more

It seems that mobile reception along German high-speed train routes has improved lately (at least compared to 2019). I’m sitting in an ICE 4 between Hanover and Hamburg, and I’ve initiated a speed test via USB tethering. My mobile phone contract is limited to 10 Mbps, but I seem to be able to take full advantage of that. ⌘ Read more

In search of a new printer
Update: Thanks for all the answers! I have now tried to repair the ink cartridge, now something is printed again, but somewhat blurred. I finally decided to buy a black/white laser printer with scanner, a Xerox B225 as B-ware. I will probably report… ⌘ Read more

In search of a new printer
At the moment I do not have a working printer at home. I have an inkjet printer, but due to a long period of non-use, the cartridge or the print head has dried up. If I want to print something, I have to do it in a copy store or a drugstore. This is possible, but especially if I need to print something spontaneously, or only a few pages, then the effort is annoying. ⌘ Read more

Profanity: Profanity on Pinephone
Hi all,

So far, in my pinephone I used mainly GUI applications, because I was using a touch screen. Terminal applications are not user-friendly when it comes to one-handed operation.

I tested different distributions on my pinephone (mobian, manjaro, archarm), but usually most based on Phosh. In my opinion it is currently the best mobile graphics environment and stable as well.

In Phosh I tested few xmpp clients:

** What is an addressing mode? **
In a recent post I referenced addressing modes. But what the heck are they!?

Setting the stage

The instruction register holds the program instruction that is currently being run.

A fixed number of bits within the instruction register represent the operation, e.g. “op. code” — examples of these instructions include things like add, subtract, load, and store. We can imagine the instruction register like this:
