Sind da auch Konnektoren z.B. zu Threads und Bluesky dabei? Falls ja, fände ich die Zahl nicht mehr wirklich beeindruckend. Darüber hinaus wäre es interessant, was als "Post" definiert und gezählt wird.
@⚝ Mirko ⚝ Annahme ist, dass da auch die Threads Beiträge mitgezählt werden, die im Fediverse ankommen. Bluesky ist nicht enthalten. Als Post zählt jeder Beitrag, also auch die Kommentare.
Oh je, jetzt kommen so viele von den kommerziellen Macroblog Plattformen in's Fediverse, denen erzählt wird Mastodon wäre für sie eine gute Wahl. Die Irritation und Enttäuschung ist denen regelrecht ins Gesicht geschrieben, wenn nach 500 Zeichen Schluss ist und die Texte nicht sonderlich schön formatiert werden können.
Daher, beratet die Menschen nach ihren Bedürfnissen und nicht den Euren. Empfehlt ihnen, was zu ihnen passt.
Multidrug-resistant bacteria get lots of attention. But some #fungi, too, have become immune to almost every known treatment available, posing another critical threat to global health. Now, researchers have found a compound that seems to kill fungi in an entirely new way: mandimycin. „A new #antifungal is always exciting and very welcome,” says Oliver Cornely.
But first, let me tell you all that a Mister FPGA together with a Retrotink 4k is a pretty neat combination.
We all know that latency is the bane of simulated retro hardware. While it may not be immediately obvious, it's there as a wet blanket on top of everything you do. You may not be able to put a finger on that one particular thing that makes it feel less like the original thing, but once you change it, you notice, even if it's something as simple as when typing on the keyboard. Interactive latency was so much better on these older machines than even a high-end modern computer, thanks to the extra (mostly software) layers between the keyboard and the screen.
Perhaps this is something only people who grew up with these devices would notice, and to be honest, this may perhaps make younger people able to enjoy the classic games more.
Anyway, the classic C64 game Uridium has a minigame between levels where a two button blink on and off, one containing a bonus number and the other is "exit". The goal is to press the joystick button when the number light sup, which then moves to a higher level that blinks faster.
On the MIster FPGA with the standard HDMI output, I was never able to get higher than 4, and to get the fourth one I had to compensate for latency by aiming for "exit" instead of the number.
Well, with direct video output and the Retrotink 4k I managed to beat all 6 levels, each time aiming for the number.
I think using a 4k display with VRR support and HDR, connected to the Mister FPGA and the Retrotink 4k is the closest you can get to the original experience.
But, my 4k display has one problem. It's a 27" screen, which is way too large. An Atari ST program on such a large screen looks bad, no matter how well the CRT emulation works. The old TV's were much smaller, so in order to simulate this I need a more appropriate monitor.
So, the question for all of you:
Is there a good small monitor, about 16" or so. It needs to be 4k, support VRR and HDR, and preferably also high refresh rates?
Wow, vor 3 Wochen habe ich mich noch über den ersten 100er des Jahres gefreut, heute waren es schon 153 kWh Strom vom Dach. Das sind schon fast 3/4 der Maximalmenge die die Anlage im Sommer liefern kann.

Did you know that the "fiercely independent pro-Europe" news site euronews.com is 97% owned by a VC firm run by a close friend of Hungary's Viktor Orbán?
That the the International Federation of Journalists called for a European parliamentary inquiry into the Euronews manipulation of the 2024 European Parliament election?
That aforementioned VC firm was fined for facilitating money laundering and financing of extremist organizations?
New antipattern just dropped! Maybe also with root privileges so it works better for installing things. And we could add a looped pipe operator, so that stderr is automatically sent back for further refinement.
I think we are not thinking deep enough. How about we actually build a completely new build-system independent of the other ones, let’s call it vibemake. And you proompt it in the project level vibesfile, and it will just run all the compilers and everything for you. That way we can save on all the bloat of the other buildsystems. And for compatibility we ship it as an electron app. (okay this idea is too horrible to not end up on the todo pile).
quick, start a funding round, I think we got a winner! GPT take the wheel! Nothing could go wrong. The world is not ready for this, and no one wants it, but it will be made anyway.
/s aside, I do wonder, once someone starts selling shit like that, will there be forums discussing the best structures and formats for readmes? Will there be prompt injections via externally include images? What a time to be alive! Also, make it a .txt with markdown syntax: llmstxt.org/ 🤡.
does anyone know a museum or collection that contains a working/operational Ericsson AXE10 digital telephone exchange? #telecom #ericsson #history #retronetworking
Instituut Beeld & Geluid in Hilversum has taken over the depot of the old telecommunications museum. They *may* have one. But the only person I know there (@CMFrancoise) may be far removed from that stuff.
There's a wonderful little telephone museum in Jefferson, Iowa, USA. It's run by the town's independent Jefferson Telecom company. I don't know the specifics about their holdings. Here's contact info: jeffersontelecom.com/
a collection in Melbourne, Australia has one in storage that "ran when parked", but it's not on public display and (as far as I know) hasn't been powered on since its preservation.
The National Communications Museum (also in Melbourne) has an AXE-104 (a locally-developed, miniaturised version of the AXE that uses a microprocessor instead of a real APZ) on display (sort of) that was working, but hasn't been powered on recently and unfortunately most of its spare parts were destroyed.
guess i'll finally have to get into rf circuits and tuning (famous last words). also is there any workable foss 3d fem simulation thing that makes sense for playing with ghz antennas and enclosure geometry/materials? or is this a domain exclusive to expensive proprietary software? are these things even solvable purely in simulation with current computers? can someone just do it for me? :D
i know i can probably buy this as a service from i.e. ezurio but it would be much better to understand more and also being able to share the techniques and insights openly
People at work who do research seem to tend to use COMSOL and similar (or their own code) but that's probably going to be way out of your budget and also probably more than you need.
A quick search does find some freeware, no-cost or oss tools for rf design. Edit: such as OpenEMS: openems.de/
@jannem seconding OpenEMS. Kicad 9 brings some niceties to make the process less manual as well. I learned from youtube.com/@panire3, plenty of examples to get going
Your Friendly Engineering Colleague
My main interests are low-voltage electronics (under 75V) and electromagnetic compatibility (EMC).

also, when it comes to HF, it might help to reach out to radio amateurs, some of whom have a ridiculous level of expertise in HF circuit design while being almost as far from monetarily motivated as you can get. They do this for fun and open hardware is also part of their culture...
Blender and graphics in general uses raytracing and the view of light as particle, while RF requires using the wave eq. If you discretize space and time this can in principle be simulated as a local operator, the field at time-space location (x,y,z,t) depends on the field near (x,y,z) at time t-1. I think the most challenging part would be to model the materials involved.
I was chatting about this with a physics postdoc wondering about a free software solution, and he suggested meep github.com/NanoComp/meep This would be more like povray for RF. The simulations are slow, and require tons of memory because of the voxel representation, but you get an animation of the the waves propagating through space...
rf engineer for automotive applications here, simulation really depends on how complex the environment of the antenna is and how well the one doing simulations knows his handywork.
I am not very well versed in fractal antenna design. But since this is a geometric repeating design, it shouldn't be too hard to match it to 2.4Ghz or dual band. First you would choose a shape like a triangle(or two) and then multiply it while shrinking at the same time(basically making cut outs in the big triangle). have a pcb mill at work wich isn't functional at the moment but maybe I can do some work on it in the next weeks. Others might jump on this idea as well.
@morl0ck I'm a EE working designing wireless modems and work closely with several antenna designers and have access to the sim tools and rf chambers. Even if you have the simulator the results will be garbage in garbage out. You need an expert operator and you need to correlate the model with real measurements. I would start by a clear goal definition with 'before' measurements, a review of existing/competitive/reference designs and literature. You may not need to design anything new.
@poleguy half of that statement depends. Antenna simulation is quite good in certain applications, a big OEM car manufacturer has switched to simulation development because they achieved extremely good correlation. But yes no need to reinvent the wheel here. Could use a simple wifi antenna with a plastic lid instead of the pcb one to improve reception. But more fun would be if we could use the mnt logo as an antenna 😁 that's wers the fractal design could come into play.
@morl0ck no, not completely. but i need a heatsink, and the remaining copper square provides it. if switching the lid to aluminum, i guess it needs to be a hybrid of materials with one part for heatsinking and the other part for transmissivity. but how big does this "opening" for the wifi signals need to be? and is it enough if it's mostly on one side?
@morl0ck @poleguy this is the current "OK" setup. it's fine if you're in the same room as the router. but if i'm in the next room over, it only works ok if the antenna is pointing towards the router in the other room. (pointing through the back of the lid). a smartphone (fp5) at the same position does not suffer from this "directionality". or could it just be wifi 6 vs wifi 5?
did you use 2.4Ghz or 5Ghz WLAN? That should be the main problem. Could very much be that the heatsink blocks signal when you're not in front of the router. A network analyzer would help with finding out. Is there one in the space you have in berlin? Maybe some lab nearby?
@morl0ck So a VNA (I recommend the NanoVNA for a decent cheap/capable openish entry to the space) will more or less tell you if your antenna is “tuned” properly. A demo of this process can be seen here: youtu.be/xa6dqx9udcg
Now a VNA will not show you what the RF does after it leaves the antenna or how well it receives through the case. I’m not sure what the best way to do this is, but you could do rough measurements with a signal analyzer.

yes a vna. Easiest thing would be to set the frequency range from 2Ghz to 3Ghz and a similar span for the 5Ghz band later Select S11 as measurement type and place a marker on 2.4Ghz Connect the antenna and than place it on the normal backplate and after that (if you have) on a copper free pcb of the same size. The readings for the marker should gibe a clue how big the influece is
the higher the frequency the more it turns into magic and random chaos. 5Ghz can be very succeptible to influence. Sidenot on smartphones: the antennas are shit. No space, a dozen of them in a tiny enclosure. They re not really matched or decoupled from ome another so smartphones are not good as a standard to compare to.
The farther away you get this antenna from any metal, the better it will work. I've already had some experience with this exact type used in another project (ClockworkPi uConsole).
Its better in your case because it's not directly fixed to the metal but of course you'll always have shielding and reflections from nearby metal objects. In a compact device you have to live with that.
Measuring with a VNA (as mentioned below) will not give you a lot of info. It would tell you how good the antenna works generally (ideally measured as far from any metal as possible). In your enviriment, you already know that the situation is not ideal, so not a lot to gain from measuring it.
A fractal antenna design that could be used for Wifi, Bluetooth and more would be awesome. I have no Idea how to do this though and still consider it Magic
I think the easiest way forward would be to make the copper heatsink asymetricly smaller on the antenna side and to check if there is better (more RF transparent) PCB Material available. These specs should be available. There are certainly better ways, but this is easy and probably worth a try.
@andi @poleguy @morl0ck thank you! i also reviewed the antenna datasheet/app notes again and agree it's worth to try moving the copper away even further. also bigger area antenna could be interesting?
I also read the stuff here. I think this is the right idea, although I suspect the radiation pattern needs to be rotated 90 degrees so the null is not shooting out the side of your device: mastodon.social/@pff/114178717…
Here are the design files I have so far for the PCB antenna. One is the kicad footprint for the antenna. Another is the prototype PCB I made and tested.
@andi I realize it's not an exact match. This is intended to be mounted on the top of a horizontal ground plane. In this case it would be rotated ninety degrees, so the polar pattern will be rotated incorrectly when the screen is open.
@morl0ck I'm not technically an RF engineer, but I'll try. You have to stop thinking of one piece as the antenna, and other things as things with openings or things that improve the antenna. Anything in the near field at the frequency you are using _are_ part of the antenna. So your antenna design includes the case, the heat sinks, the cables, the plastic, the FR4, and their relative positions when opened/closed rotated, etc. FR-4 will have a dialectric constant different than plastic...
Free 3D EM modeling and simulation software recommendations are CST (non-commercial-use version) and ELMER. Unfortunately neither are easy to use for newer folks.
There are a few much easier to use tools for lower frequencies. I plan to learn and use MMANA-GAL (free version) for an upcoming #HamChallenge antenna simulation activity. This tool also has helper-apps for matching and other needs.
We will probably have a *@Metafunk ⚡ talk at @metalab this wednesday evening about antenna simulations. I'm not sure yet but if it happens, it will be streamed too.
It's mostly about sub-Ghz Frequencies but the principles still apply. Ralf, OE3RSA has written some new tool for the purpose (don't know exactly yet. have to see the talk first)
He does a lot of antenna simulation with genetic algorithms - pretty advanced stuff. There are some things to read about it on his website: runtux.com/
@HeNeArXn I have a Sonnet pro seat including the far field radiation pattern option.
I'm not an expert at designing antennas - far from it - but if you have geometry you want me to try I can simulate it.
The one big limitation is that it's a planar solver which means that you can't model e.g. a parabolic dish, and it can only model radiation normal to the PCB surface (so a patch antenna is fine, but it wouldn't give accurate results for a PCB yagi that fires sideways).
But if you have a simple patch design or PIFA or something you want to tweak I can definitely help with that.
@azonenberg @HeNeArXn that's cool, thanks! but just to understand... you probably can't plop the 3d case part(s) surrounding it into that simulation to see how they affect the antenna, right? as i understood those parts become part of the antenna and detune it?
@HeNeArXn Yeah that would potentially be tricky. Sonnet is really meant for PCB or RFIC/hybrid modeling and when you try to do more system-level stuff it struggles.
In the year 2000, we celebrated the first Gigawatt of photovoltaics - after more than 40 years of research and implementations. Now, we install that capacity twice a day.

Changing the name is a possibility for the future; for now we have what we have. A hostile fork is always possible, but you do need a team of developers.
I understand the scope of work and don't expect miracles. Perhaps rewording your FAQ would make it seem a little less hostile to the idea that the name might be inappropriate.
A few years back, someone forked GIMP into Glimpse because the term “GIMP” was offensive in a way.
Not just limited to the name, but the fork also aimed to do better than what GIMP offered, with a potential to introduce an easier user interface and …
@supertobi @mxjaygrant yeah I know all that. But the thing is, the more I grow away from my nerdy teenage self, I understand it less and less. The "coincidence" while finding an acronym is just incomprehensible. It might have been "funny" back then, but now it isn't any more. The FAQ reads like the project didn't grow up which is sad because the program is great and the new people involved are as well. So I wonder why keep that cruft.
@piratenpanda @mxjaygrant Remember, renaming costs money and is a lot of work that the team might prefer to invest in the product. Should gimp be renamed? Probably. Do I want to take on the work and the costs? Definitely not.
@supertobi @piratenpanda @mxjaygrant They aren't open to changing the name. If they were and actually said we want to but we need to do such and such and it costs money they would actually get support to help. Right now they are just being obtuse.
@CmykStudent @supertobi @piratenpanda @mxjaygrant y’all might want to update the FAQ if it’s an actual possibility! Based off of that it sounds less like “its difficult to change such an old name” to “we won’t change it and in fact it’s for some principled reason”
Hey GIMPS, thanks for that amazing Upgrade and many hours of hard work! i would like to ask very gently when gimp 3.0 will be available on linux mint; does anyone here know?
have you considered dropping "Program" from the name. It's implicit that's a program and then the acronym would not be a bad word anymore (I think, English is not my first language).
@freezr it's a fact that it's a offensive word, regardless of why they are complaining. A non-offensive word would make everyone happier and drive more adoption to the program. Many people have left experiences where it was not chosen at work because of the offensive name.

Ah, Musk is the great Genius and SpaceX a success. Sure, dream on: „Over 50 years ago, NASA was able to get its Saturn V, a rocket nearly as large as Starship, to fly without ever having a failed launch over its 13-launch, six-year operational lifespan. This was a rocket designed with computers less powerful than a Casio watch, built with far less accurate techniques and materials, with check systems and procedures infinitely less sophisticated than anything today“.
I'm micr0, the creator of @altbot, the open-source bot that helps generate alt-text for images on the Fediverse to make content more accessible.
I have some exciting news to share - Altbot no longer uses Google's services! Many of you expressed concerns about privacy when I first launched Altbot using Google Gemini, worried about your images being processed on their servers and potentially used for training.
I promised to fix this, and I'm thrilled to announce that Altbot 2.0 is now running entirely on my own hardware using the Ovis2:8B model. Your images are processed locally with absolutely zero data retention - your content never leaves my server and isn't used to train any models.
The new system is fully GDPR compliant, and descriptions are even better across all 11 supported languages. What's also cool is that the setup is significantly more energy efficient, with 36% of power coming from clean sources. Altbot now even shows you how much energy was used for each request!
The only things Altbot 2.0 records are that a request happened, how long it took, and what language was used. No images, no content, no personal data - nothing that could identify you.
Building this upgrade was more expensive than planned - I needed a more powerful server with an A5500 GPU, which exceeded my budget by about $900 that I covered out of pocket. If you appreciate this commitment to privacy and accessibility, any support through my Ko-fi page would help recover these costs and keep Altbot free for everyone: ko-fi.com/micr0byte/goal?g=18
Thanks so much for your support! I built Altbot because I believe accessibility shouldn't compromise privacy, and now that vision is reality.

Every story I hear from federal employees negatively impacted by the Turd Reich is the same: Literally ZERO empathy from their own friends and family who voted for the orange gasbag. Some have even been told they must have been unnecessary or they wouldn't have been cut. The death of empathy is, indeed, a sign of civilization in decline.
Some time ago Anna's Archive launched a contest to create a visualization of the “ISBN space,” i.e., all books registered through this code. The results are spectacular. I recommend that you search for any book in the winning tool for an authentically Borgesian experience.
