FYI: The problem at hand is an existence problem. No real construction of any real formula for the solution is provided, only a singular perturbation expansion. In short: The problem is about whether a solution (of the NS Equations with ext

wow it is great to see that there is still life in distributed programming languages. I would like to know what are the differences to MPI programming, chapel and PGAS languages like Co-Array Fortran and the rust extension ChoRus? Can you y

There is a free emulator here: https://www.fullbucket.de/music/fb3300.html The PS-3300 is a 3 layer synth with 49 voices where each voice has its own VCO/VCF/VCA. So you end up with 16 voices when you use 3 l

I think the battery life of a smart watch cannopt be underestimated. I have all the old pebbles which I love darely but then I got a Amazfit Bip and I stayed with it until today. One month (!) of battery time with a HR sensor and notificati

People talk about a Butlerian Jihad against AI as if you could just ban LLMs and be done. I bet some govermenst would like to do that for ordinary people. They can ban visible products (chatbots, public APIs, GPAI services), and laws are al

One thing to consider: The (well-known) Sapir–Whorf hypothesis (if dont know it, look it uop) is often invoked for natural languages, but there’s a pretty direct analogue for programming languages: the language you "think in" duri

You can of course use any language but here is my advice: you should use the language that you know best to make your life as uncomplicated as possible when you want to understand what the LLM was creating. Remember, you are the judge wheth

by fxj 5mo ago
In the long run there is no alternative to really reading your codebase and understanding what is going on. You can leave the nitty gritty details to the LLM but you have to be in the drivers seat and know how the parts of your codebase wor

God I miss openstep and CDE. It needs 16MB RAM (yes MB!) and together with a lighweight firefox clone you get everything you need. Eye candy is nice to have but not at that cost.

He also talks about picoclaw (a IoT solution) and nanoclaw (running on your phone in termux) and has a tiny code base.

He also talks about picoclaw which even runs on $10 hardware and is a fork by sipeed, a chinese company who does IoT. https://github.com/sipeed/picoclaw another chinese coompany m5stack provides local LLMs like Qwen2.5

TOTP is also just password + some computation. So where is the difference? There is a lot of security theatre around TOTP with the QR code and then need of an app but you can write a 8 liner in python that does the same when you extract the

WebAssembly in the browser does feel great when you look at things like Pyodide/Pyolite, JupyterLite, xeus, webR and even small tools like texlyre – you get a full language/runtime locally with zero server, just WASM and some JS g

MCP is just a small, boring protocol that lets agents call tools in a standard way, nothing more. You can run a single MCP server next to your app, expose a few scripts or APIs, and you are done. There is no requirement for dozens of random

Get money from donors. Wikipedia shows how that can be done. Or get money from the EU. Mozilla is a strawman for google that they can claim there exists another browser that is not chrome because of antitrust laws. And now that Microsoft fo

I see it at our place that seniors get more productive but also that juniors get faster on track and more easily learn the basics that are needed and to do basic tasks like doumentation and tutorial writing. It helps both groups but it does

In my experience AI is wikipedia/stackoverflow on steroids when I need to know something about a field I dont know much about. It has nice explanations and you can ask for examples or scenarios and it will tell you what you didnt under

by fxj 1y ago
I agree, you need to know the "language" and the keywords of the topics that you want to work with. If you are a complete newcomer to a field then AI wont help you much. You have to tell the AI "assume I have A, B and C and n

by fxj 1y ago
Also AI cannot draw conclusions like "from A and B follows C". You really have to point its nose into the result that you want and then it finally understands. This is especially hard for juniors because they are just learning to

Learning == Compression of information. It can be a description by a shorter bit length. Think Shannon Entropy and the measure of information content. The information is still in the weights but it is reorganized and the reconstructed sente

How good can you recreate an image that is described by words? Obviously not bit by bit and pixel by pixel. You get something that resembles the original but not an exact copy.

It is at least as lossy as jpeg compression. Details get lost and artifacts are generated.

how long would it take to do a complete memory dump of your brain by voice stream? days? months? years? this is more like writing one's autobiography.

by fxj 1y ago
The question is: Is it like jpeg compression where the errors do not accumulate but the image comverges to a self inverse compressed image or does the data set converge to a single point which is meaningless?

just tried this: take the graph of the functions x^n and exp(x) how many points of intersection do they have? chatgpt gave me the wrong answer, it claimed 2 points of intersection, but for n=4 there are 3 as one can easily derive. one for n

That not only works for compilation but also for more general code transformations like code parallelization with OpenMP in C and Fortran, Array-of-lists to List-of-arrays, or transform python code to parallel C-code and make a python modul
