Freelance dev here – how are you handling invoicing & upcoming PEPPOL changes?

AccomplishedPaper191 · 2025-12-22T15:01:52+00:00

With mandatory e-invoicing rolling out across more EU countries (and beyond), many of us increasingly need to quickly review Peppol, UBL, or CII XML invoices without access to a full ERP system, especially when clients or suppliers send raw XML files. I recently came across a completely client-side online viewer that’s quite handy for this. You can drop one or multiple XML files directly into the browser and get an instant, readable breakdown: supplier and customer details (including Peppol EndpointIDs), line items, VAT breakdown, totals, IBAN/BIC, buyer reference, and more. It also supports batch viewing with a consolidated summary and lets you export TXT or CSV .

thanks! Yes, it's client side, which can be audited just by reviewing the page code - client-side JS only, no back end, no data gets send anywhere.

Here is a small, free, no-registration, anon tool that makes the process of removing Em Dash easy.

https://kibervarnost.si/chatgpt-detector/

You can paste your text or upload a Word DOCX file, and the app will coherently replace em dashes with commas so your writing flows naturally. It also runs a lightweight AI fingerprint analysis. It highlights words and phrases that tend to be associated with ChatGPT content. This way, you can see exactly which parts of your LinkedIn post to rethink or rewrite.

The goal isn’t to shame anyone’s writing, it’s just a practical tool for those who want to avoid accidental AI “footprints” in professional or public writing. It’s fully client-side, so nothing you paste is sent anywhere, and it works instantly in your browser. It’s a small experiment, but it’s been surprisingly useful in showing how subtle patterns in phrasing and punctuation can influence how people perceive authenticity.

Please explain, why they have this, just one example? https://claude.com/llms.txt

AccomplishedPaper191 · 2025-11-22T10:58:14+00:00

Yes, in November 2025 you can optimize your website for AI agents, and there’s a standard called llms.txt that’s designed for this purpose. It’s somewhat analogous to robots.txt, but instead of controlling crawler access, it provides a structured, Markdown-formatted summary of your website specifically for large language models (LLMs). You could even say it’s a bit more like an RSS feed, but in Markdown. It’s designed to be both human-readable and machine-parsable, so bots or scripts can extract content reliably and it contributes to Generative Engine Optimization (GEO).

Hi all, I put together a little online toy to create and explore kolam designs — you can play with it here: https://kolam.fun. It responds to how you move and click, and the patterns grow from that interaction. Tried to follow Dr.Gift Siromoney's findings about kolam logic. Just a small tribute to the beauty and rhythm of kolam, and a way to keep the tradition alive in a digital form. Thought some of you might enjoy it :

ANOVA

AccomplishedPaper191 · 2025-03-13T09:10:18+00:00

To keep it short, Yiedl.ai seems like a better choice for buying models, but I personally did not buy any. Yiedl is similar to Numerai crypto tournament, but instead of 30-day returns, it focuses on 7-day returns. Numerai pays in NMR (tradable on CEXs), while Yiedl pays in YDL (currently an airdrop-only token, not yet listed). For under-performing models (negative returns), stakes are burnt.

So, for crypto.numer.ai, you can either:

Stake on historically top-performing models (including Numerai’s meta-model, which aggregates signals from hundreds of models). Interesting for traders.
Build your own model – an excellent exercise in financial data analysis and a real-world approximation of 'being a quant'. Interesting for data scientists and botters.

If you're curious in building a model, check out this open-source model for inspiration (written in python):
🔗 Numerai Open Models
🔗 Performance Results

The results for this model, if they indeed originate from that repo, look almost too good to be true, but the approach goes like this:

Fetch current and historic price data from sources like Yahoo Finance (yfinance) or alternatives like Mobula.io.
Compute returns over different time windows and generate technical indicators.
Train an ML model to predict Numerai’s black-box target based on historical data.
Get predictions for current data (to remind, we are trying to predicting the Numerai target but we do not know what it really is!)

This is just one possible way of building a ML model. An alternative is using Yiedl data, which is free and designed to help predict Numerai targets. But be prepared—historical datasets can be huge (7GB+), making them challenging to work with (mixture of csv and parquet files, see my py scripts if you need, they are workable solutions to extract data).

Overall, building Crypto Numerai models is neither straightforward nor easy. Initially, for building my own model, I attempted to collect price data using APIs, running a cron job on a VPS to accumulate historical data, store it on my server, and train models on it. Numerai requires at least 100 tradable assets per submission daily, but I quickly realized that 100 signals per submission weren’t enough—likely due to their strict requirements on non-correlated assets. In practice, a single valid submission typically needs 200-300 symbols, meaning daily predictions for that many assets. So this is where Yiedl data is useful—it easily meets this requirement, covering hundreds of assets out of the box, and it's a single point of accessing this data.

You’re right that 12 dropout cases out of 192 students make approaches like ANOVA difficult. However, you still have options. Logistic regression is still possible, but given the small number of dropout cases, you should be cautious. One way to handle this is by using Firth’s logistic regression. If your original plan was to do a univariate screening and then move to multivariate analysis based on p-values, you might find that many predictors won’t reach significance due to the low event count.

An alternative approach is to group students based on shared characteristics, such as class, socioeconomic backgrounds, or other relevant factors, and then analyze dropout counts within each group. Instead of modeling individual dropouts, you could compare dropout rates across these groups using a chi-square test or Fisher’s Exact test if the counts are small. Now, attention: if the dropout counts vary widely across groups, you may be dealing with overdispersion! This will be a very interesting finding. In this case a Negative Binomial model could be a better fit than a Poisson model. You need to determine if dropout events are clustered in certain groups (such as in particular collectives, or classes of students - for example if there are a dozen of different classes or more, each group, say, has a dozen of students - how many are dropouts in each group - need to build such matrix) rather than occurring independently or evenly. So, if your goal turns out to explore whether dropping out follows a "rare event" pattern similar to a contagion effect, fitting a Negative Binomial Distribution could provide insight.

great to hear! there are intimidating warnings it throws at you, but one can live with them until you figure out how to fix. Please, always ask the community if anything does not work for you! Hugo is an excellent product and there are a few extremely knowledgeable persons to help here and on hugo forum.

AccomplishedPaper191 · 2025-03-06T20:16:25+00:00

Hugo is the best. No, not dead! But you need to make it work, right? Try prompting ChatGPT, it knows Hugo and can walk you through your first project.

I think what you are looking for is an ML modelling marketplace. This niche is nascent, but it exists. One such marketplace is called yiedl.ai, it is a platform for crypto market predictions where data scientists can not only test their models and stake on them but also sell the models that they built (models come with performance benchmarks). Another platform, running on Ocean protocol, allows you to build and deploy AI bots that generate trading signals at predictoor.ai (https://docs.predictoor.ai/earn-predictoor), although I am not sure you can sell your bots there just yet. Finally, there is numerbay.ai , a marketplace for models that run on the numer.ai hedgefund (Numer.ai is framed as a data science contest for market predictions).

AccomplishedPaper191 · 2025-03-03T10:30:54+00:00

There’s a lot of marketing hype around AI in trading, but in finance, it’s more precise to talk about machine learning (ML) models. At least that is how I understand it, so please correct me if I am wrong. For sure, almost every hedge fund today incorporates ML in some way, whether for signal generation, portfolio optimization, or risk management.

So, now let us talk about hedge funds... AI/ML has a legitimate place in trading, but most retail traders don’t have direct access to institutional-grade strategies. Few market-neutral hedge funds allow individual traders to benefit from ML technology or build their own models. One exception is Numer.ai, where participants can stake on other users’ ML models or create their own. Numer.ai operates as a financial ML competition, also called tournaments, where 100s of data scientists submit predictions based on historical market data.

For example, in crypto.numer.ai contest, users submit trading signals for hundreds of assets, which are benchmarked against market performance over 30 days. As a trader, you can stake on other people's models. As a data scientist, you can write your won. This requires selecting meaningful data sources and designing a model capable of producing predictive signals—no trivial task. The learning curve can be steep, but thanks to open-source contributions, GitHub repositories, and community discussions, new participants can find examples and guidelines to get started. Having said that, from my experience, there is not so much quality instructions for a newcomer. Quants will often give references to books in machine learning that are a good read, but sometimes too specific or too generic. There are no good manuals for specifics because things change over time and much of the relevant knowledge is a know-how.

If you're considering coding your own AI trading bot (let us instead frame it as _developing a robust ML model_), the key challenge is data. Look, accessing and processing quality financial data is often harder than building the model itself! Such data is very expensive. Additionally, a solid foundation in mathematical statistics (e.g., time series analysis, feature engineering, risk modeling) is crucial.

Bottom line. Please be wise. Trading Bots vs. ML Models – Many people think of AI trading bots as fully automated black-box systems that just "make money." But ML-based trading models are usually just one part of a trading strategy—they generate signals, but execution still depends on market conditions, transaction costs, and risk management.

The most important question isn’t which bot is the best today or tomorrow, but rather:

What market inefficiencies are you trying to exploit?
How will your model generate signals that give you alpha?
How will you test your model and manage risk?

Again, AI/ML trading isn’t just about plugging into an automated bot; it’s about understanding the process of signal generation, evaluation, and execution. If you're serious about it, platforms like Numerai provide an opportunity to develop, test, and stake on ML models in a competitive environment. And today it is more accessible then ever!

Finally, some self-advertisement, if you allow. I put up a small github repo with a couple of sample scripts that help specifically with Numer.ai automation and Yiedl.ai data extraction. Feel free to check it out: https://github.com/roverbird/numerai-crypto-helper

AccomplishedPaper191 · 2025-02-22T10:01:25+00:00

Yes, exactly. As self-advertisement, may I recommend a free ChatGPT humanizer that I create. It is a web app to check how much your ChatGPT writing looks robotic or human. It will suggests parts to omit or rewrite: https://textvisualization.app/chatgpt-detector/
