I follow commodities and couldn’t find any good data covering global mining production, so I wanted to test if I can use LLMs to efficiently build such a dataset from scratch. I documented the process of going from unstructured company filings to a structured dataset that could be used in systematic research.

• Github repo
• Live app

All the production information is public, but it is scattered across inconsistent websites and reports.

When talking to central data teams at hedge funds or to data providers directly, building a new dataset that is provably correct and has reliable updates always sounded like a very big challenge.

For each company, I want to extract production figures that are comparable:

• What was produced
• Which operation produced it
• Which period it covers

The hard part is normalization since every region and company reports differently (if not SEC):

• Different units across reports like copper in kt, million pounds, or wet metric tonnes
• Fiscal years don’t align (calendar year vs June FY vs September FY)
• Some report on a payable basis, others contained metal, others equity-adjusted
• Product naming is inconsistent (“copper concentrate” vs “cu conc” vs “SX-EW cathode”)
• Important details are sometimes hidden in headings, footnotes, and surrounding text (e.g. ownership percentages, and reporting methods)

The “old” way of doing this would be to write a bespoke ETL pipeline for each company.

The “new” way that I tried is using LLMs to generate, monitor, and maintain deterministic ETL code. An agent then runs the pipelines and jumps in whenever the script fails and needs to adapt. The idea was to have self-healing data pipelines: when a website or PDF layout changes, an agent investigates, fixes, and tests the extraction or transformation code. If it can’t figure it out, it escalates to a me for review.

1. Scraping code monitors company websites and captures new reports.
2. We can then extract the raw production figures from the reports. A mix of traditional PDF parsing and gemini-3.7-flash worked very well here. The extraction also returns the location in the source (e.g. page 123, table X, row Z, cell Y) which is very helpful for QA and source grounding.
3. To normalize the data, I choose between different transformation strategies:
   • can the data be parsed as is?
   • can I generate deterministic transformation code, e.g. a regex mapper
   • last resort if no deterministic approach is possible: use an LLM to map the data
4. Then we validate the data against various QA rules. What works well here is that we treat every extracted value as wrong until it passes validation (guilty until proven innocent).

I’ve open-sourced the dataset (pipeline code will follow). Curious to hear your feedback or experience with building such ETL pipelines and datasets.

Hi, i want to try my continuous time hidden semi markov model. However, data like that is hard to find. Does anyone know data that:
– Fulfills the snapshot property of CTHMMs

– Time gaps are uninformative

– Is somewhat long enough

Classic data is disease progression data with some continuous biomarkers. I tried many of them but they dont work as well. I tried astronomy on the SS CYGNI, which worked fine but im looking for other alternatives. Anyone got an idea ? Its pretty hard tho

🕷️ A Small Data Science Challenge for You: Spidey Tracker

Hi everyone! 👋 I have a small dataset and data science challenge for you. 🕷️

I’ve published Spidey Tracker on Kaggle, featuring 86K+ synthetic sightings, crime records, and movement data.

The challenge is simple:
Identify real vs. fake sightings, predict the next location, and try to find the hidden operating base. 👀

I went looking for split-level race data and found that the Hyrox results site publishes far more than I expected. Every finisher, every event, back to the 2018/19 season, roughly a hundred events a year.

https://results.hyrox.com/

The useful part is the granularity. Each athlete has two tables. A summary carrying the 8 run splits, the 8 station splits, and one lumped “Roxzone Time” for all the transitions. And a “Race replay” listing the raw mat crossings: coming off the run, entering the station, leaving the station, rejoining the run. Four mats per station, so the transition total decomposes into arrival and departure. The site never presents that split as a number anywhere, but it is sitting right there in the replay.

There is no documented API and no bulk export, so it is HTML scraping. Three working URLs, using New York 2026 as the example:

# every event id for one race https://results.hyrox.com/season-8/?pid=list&event_main_group=2026%20New%20York # one division, 100 finishers per page https://results.hyrox.com/season-8/?pid=list&event=H_LR3MS4JI162A&page=1&num_results=100&search%5Bsex%5D=M # one athlete, both tables https://results.hyrox.com/season-8/?pid=list&content=detail&event=H_LR3MS4JI162A&idp=LR3MS4JI52379D 

Season path is /season-8/ for 25/26 and /season-9/ for 26/27.

Two things cost me time. Big races split days by sex, so a day returning 1067 men and zero women is a scheduling artifact and not a broken query. And the detail page has a tab strip that repeats both table headings, so anchoring a parser on the heading text matches the tab link instead of the table and silently hands back the wrong rows.

It does reconcile, which is worth checking before you trust a parse: arrival plus departure sums to the reported Roxzone Time within a second, and runs plus stations plus transitions equals the finish time within about 8 seconds of split rounding.

I pulled 248 finishers across two events to see whether the arrival versus departure gap was real or just where the mats happen to sit. Departure ran about 1.5 times arrival for 97% of them, holding across both venues and both sexes, which is hard to explain as geometry.

Disclosure since it is relevant: I make a race timer for this sport, which is why I went looking in the first place. The data is Hyrox’s and free to anybody.

Hi everyone,

I wanted to share a project I’ve been working on under my solo brand, LegacyDataLabs. As Vision-Language Models (VLMs) grow, I noticed there’s a massive shortage of high-quality, human-validated multimodal datasets for historical handwriting—especially for niche languages like Swedish. Standard OCR engines completely blind-guess these scripts, resulting in pure gibberish.

To solve this, I built a custom pipeline that bypasses OCR text generation entirely. Instead, it takes pristine digital ePub transcriptions (the absolute “ground truth”) and dynamically synchronizes them page-by-page next to the original high-resolution handwritten manuscript images.

My first complete dataset is Doktor Glas by Hjalmar Söderberg (278 multimodal rows), and it is clinically clean.

\### 🔒 The Tech & Security (Compute-to-Data Sandbox)

To protect the data from scraping while still making it accessible for model training, I built an air-gapped, isolated Docker environment:

\* Zero Data Leakage: External network communication is fully disabled (–network none).

\* RAM-Only Access: Training scripts inspect the synchronized JSONL layers directly in intern-memory without file downloading capabilities.

\### 📦 Free Sample Available

I have officially released a 3-page structural sample (sample\_dataset.jsonl) showing the exact repository keys, author/title metadata, and chronological image loops.

You can inspect the sample directly on my Hugging Face profile:

👉 https://huggingface.co/LegacyDataLabs

I am currently preparing to scale this pipeline to dozens of historical manuscripts and would love to hear your thoughts!

\* How are you currently bypassing standard OCR limitations when training VLMs on historical documents?

\* Would an infrastructure like this be useful for your specific vision-training pipelines?

Looking forward to your technical feedback and suggestions!

Cheers!

Disclosure: this is my own dataset. I built and run the measurement, and the subject of the measurement is my own pen name, so treat the topic with that in mind. The data itself is mechanical: same 16 questions, every day, three answer engines with web access, answers scored with a fixed rubric.

Dataset (Hugging Face, CC BY 4.0): https://huggingface.co/datasets/marintkael/ai-citation-fidelity

I am thinking of starting a service where I sell the scraped data. I think I can scrape anything.

I can provide you with clean data daily, weekly or on a monthly basis.

I have not started this but I would like to know do people pay for this service.

And if you are in of those people so just comment. explain your requirements. It will take some time to setup and code all the things then I can provide you your data.

And even if you are not then I would like to know that why we can make profit on this. I have already checked the compiditiors they are not as good as I can build. That’s what I tell 😤.

I just saw the paper on ArXiV . It’s a dataset of US collegiate running club performances, the resulting analysis on them, and a software library for standardizing performances. They have several code repositories under the National Running Club Database which includes:

• a Python library, nrcd, for normalizing race results for comparison across outdoor performances with wind to performances on an indoor banked track, road performances, etc. It appears to account for course distance, elevation gain/loss, and weather/heat effects.
• the raw national_running_club_database_public_dataset.
• The [code which produced their results](https://github.com/National-Running-Club-Database/nrcd_xc_paper/tree/main) and [the findings](https://github.com/National-Running-Club-Database/nrcd_xc_paper/blob/main/output/FINDINGS_EXPLANATION.md)

Some things I found interesting (this is just a sampling, you go read the [full doc](https://raw.githubusercontent.com/National-Running-Club-Database/nrcd_xc_paper/refs/heads/main/output/FINDINGS_EXPLANATION.md) yourself):

• Teams with at least one athlete who raced 4+ times were 2-3x more likely to crack the top 15 at nationals than teams without one (23-39% success rate vs baseline). 60-80% of top 15 teams had an athlete with 4+ races.
• Men’s teams with a longer gap between their first race and nationals (i.e., started racing earlier) had significantly better finishing ranks (r = -0.283, Bonferroni-corrected p = 0.041). This didn’t hold up for women’s teams after correction.
• Single biggest predictor of an individual’s improvement rate was “experience level”. (races × season duration) at 21%, followed by how many “bad races” (a race worse than the previous one) an athlete had, at 17%. Basically race more, race consistently.
• When testing the standardization tool, the fully weather/terrain-adjusted “standardized” times actually predicted improvement slightly worse than just doing distance conversion alone (90.4% vs 93.1% R^2). Their theory was that conditions tend to get more favorable as the season goes on, so raw times naturally look like “improvement” partly because of the weather, and removing that weather effect (which is more the point of the tool) makes it a worse predictor of the raw number even though it’s arguably a more honest fitness signal.
• They checked their model for gender bias and found it performs comparably for both (94.5% R^2 women vs 90.4% R^2 men). This is not my paper, data, etc. I just found it on Arxiv and compiled the information.

There’s not much easily accessible data like this on cross country running. As the authors said, it’s all on websites that don’t support bulk download. So Normally people just stick to the Riegel and Cameron formulas for comparisons, so it’s nice to see people looking into these other factors.

**Source (original):** Ministry of Land, Infrastructure and Transport (MOLIT), published through Korea’s open data portal data.go.kr. Free, “이용허락범위 제한 없음” (no restriction on use, commercial included), auto-approved API key, 10,000 calls/day on a dev account.

– Apartment sales: https://www.data.go.kr/data/15126469/openapi.do

– Apartment rent (jeonse/wolse): https://www.data.go.kr/data/15126474/openapi.do

– Officetel, commercial/office buildings, row houses, land etc. are separate endpoints under the same publisher.

**What’s in it.** Every registered transaction, by district (5-digit LAWD_CD) and month. Sales give price, exclusive area, floor, build year, road address, and a cancellation flag. Leases give deposit, monthly rent, previous deposit/rent, contract term, whether the renewal right was exercised. Unit/door numbers are withheld for privacy, so there’s no PII in it. History goes back years; my checks were on 2026.

**Gotchas** (all of these cost me time):

1. XML only, no JSON.

2. Two generations of endpoints coexist. Legacy ones return Korean tag names (`거래금액`, `전용면적`), the `*Dev` ones return English (`dealAmount`, `excluUseAr`). Same data, different keys.

3. Tag casing is inconsistent *between* endpoints: sales give `roadNm` / `roadNmBonbun`, rent gives `roadnm` / `roadnmbonbun`. Bit me directly. (Sales is also internally inconsistent: `roadNmCd` but `roadNmbCd`.)

4. Amounts are in 만원 (10,000 KRW) as comma-formatted strings, sometimes padded — `’38,670’` means 386,700,000 KRW. Parse, don’t cast.

5. The commercial-property endpoint has no exclusive-area field at all, only building area. Don’t assume the schema generalizes.

6. Service keys come in encoded and decoded flavors; double-encoding the encoded one silently returns `SERVICE_KEY_IS_NOT_REGISTERED_ERROR`, which reads like an auth problem but isn’t.

7. You must file a separate usage application per API, not once per account.

**The gotcha worth the post: don’t pool 신규 (new) and 갱신 (renewal) lease contracts.**

Renewals are capped at +5% by Korea’s lease cap law, so they sit below market. The API labels them in `contractType`, and if you ignore that label, you’re publishing a number that’s a blend of market prices and legally-capped ones.

Seoul, all 25 districts, July 2026, apartment leases (n = 16,520; 8,310 new / 7,896 renewal / 314 unlabeled):

| | all contracts | new only |

|—|—|—|

| jeonse share | 50.2% | **43.9%** |

| median jeonse deposit | 570M KRW | **598M KRW** |

| median monthly rent (wolse) | 730k KRW | **800k KRW** |

So “Seoul is half jeonse” is an artifact of pooling — renewals skew jeonse-heavy because that’s who exercises the renewal right. New-contract share is 44% and falling.

New contracts only, by district, July 2026:

| District | n | jeonse % | median jeonse deposit | median wolse rent | median wolse deposit |

|—|—|—|—|—|—|

| Gangnam | 575 | 41% | 900M | 1.60M | 200M |

| **Seoul** | **8,310** | **44%** | **598M** | **0.80M** | **100M** |

All figures are medians in KRW, straight from the API, no adjustment. Jeonse is a deposit-only lease (no monthly rent); wolse is deposit + monthly rent, so the two deposit columns aren’t comparable.

**Disclosure — I built a free wrapper.** Getting from the raw XML to the table above is annoying enough that I published four Apify actors that normalize it: English field names, integer KRW instead of 만원 strings, per-m²/per-pyeong unit price, ISO dates, an `isJeonse` flag, unknown tags passed through rather than dropped. They’re free and need no API key of your own.

Disclosure up front: I built the project this dataset backs, and I am sharing the raw data here because it is genuinely useful for anyone mining founder or engineering signals.

This is Q3 2026 engineering momentum across 350+ startup GitHub organizations in 15 sectors (web3, data infrastructure, enterprise SaaS, robotics, healthcare, legal tech, space tech, and more). Updated weekly.

What is inside, per org: – 14-day commit velocity and velocity change % – contributor count and growth – new-repo creation – a signal label (engineering hiring burst / deploy frequency spike / infrastructure buildout / framework migration) – funding stage estimate (pre-seed through growth) and geography

Collected from public GitHub events only. No private repositories.

The research finding this backs: in a panel of 219 confirmed fundraises (SSRN preprint), a composite of commit velocity and contributor diversity preceded fundraise announcements by 21 to 47 days (median 31), a 3.4x lift over baseline. The methodology page has the full definition; the preprint is at papers.ssrn.com, abstract 6606558.

I maintain a small financial news sentiment tool and until this week it had no ground truth. An LLM assigned every score and nothing checked it. So I scored 50 headlines by hand, with the machine scores hidden while I did it.

I am releasing the labels because I could not find a set like this anywhere, and because 50 is small enough that anyone can re-label it in twenty minutes.

Link: https://gist.github.com/MicheleSanta00/ef891e48db23c1521e90cd2458ec844e

Columns

ticker the asset the headline was matched to (23 distinct)

headline the original headline, in its original language

human_label my label, one of -1, -0.5, 0, +0.5, +1

llm_score openai/gpt-oss-120b via Groq, continuous, same range

gdelt_tone GDELT’s document tone divided by 10 and clipped to [-1, +1]

50 rows. The question I asked myself for each headline was: if you held this asset, is this good news or bad news for you? That is not the same as “is the tone positive”, and the two come apart on things like a company being acquired, or a stock falling on news that was itself neutral.

Label distribution

-1.0 5

-0.5 9

0.0 16

+0.5 12

+1.0 8

How the sample was drawn

Not at random. 20 headlines where the LLM and the lexicon disagree the most, 20 random, 10 where they already agree. A random sample of a financial news archive is mostly neutral filler and would have measured my patience rather than the scorers.

Languages are mixed because the source feed is multilingual: 25 English, 19 German, 3 Spanish, and one each of French, Vietnamese and Hindi. Six more headlines were dropped because I could not read the language at all, so **this set is easier than the real distribution** and the numbers below are optimistic. The three I kept in languages I do not read I labelled from names, numbers and cognates, which is worth knowing if you look at those rows.

What I found

openai/gpt-oss-120b Pearson +0.76 (95% CI 0.61 to 0.85) sign agreement 74%

GDELT lexical tone Pearson +0.18 (CI includes zero) sign agreement 36%

Sign agreement uses a dead zone: anything between -0.1 and +0.1 counts as neutral, so the three classes are negative, neutral and positive. I am spelling this out because without it you will get a different number from mine. Treating exact zero as the only neutral gives 76% and 36%; dropping the 16 rows I labelled 0 gives 94% and 50%. Mean absolute distance is 0.28 for the model and 0.51 for the lexicon.

I also got a noise floor by accident, and I think it is the most useful number here. An earlier version of the sample contained six duplicates by mistake, so I scored those six headlines twice without realising. My own test-retest distance is 0.17 on this scale. The model sits at 0.28, about 1.7x my own inconsistency. Without that floor, 0.28 is unreadable.

Three of the ten largest disagreements were not scoring errors at all. They were headlines about the wrong company:

“Solana Biofuels reports standalone net loss” an Indian biofuel producer

“Stellar AfricaGold” a mining company

“JPMorgan Cuts CytomX Therapeutics” news about CytomX, with JPMorgan as the analyst

Name matching pulled them in and they were going straight into the daily averages. The third case generalises: banks get quoted constantly as a source of opinions about other companies, so matching on a bank’s name brings in news that is not about the bank.

In three other cases the model was right and I was wrong. An Apple executive selling $442k of stock, which I labelled +0.5 and it scored -0.2. A CVSS 10.0 vulnerability in SAP Commerce Cloud, which I labelled 0 because I did not know what CVSS 10.0 meant. And “GE trading up 2.1%, here’s why”, which I labelled +1 although it describes a move that already happened.

Limitations, plainly

One annotator, which is me, so this measures resemblance to one person and not correctness. 50 rows, so the intervals are wide. Stratified, so it is not representative of the archive. Six headlines in languages I cannot read were dropped, which makes this easier than reality. And the headlines come from a 7-day window in August 2026, so there is no seasonality in it at all.

It also says nothing about whether headline sentiment predicts price. I measured that separately and it does not.

Licence

Headlines come from the GDELT Project’s Global Knowledge Graph, which permits commercial reuse. The file contains headline text only, no article bodies. The labels are mine, do what you like with them.

What I would like back

If anyone labels the same 50 headlines, the agreement between two annotators would say how subjective this task actually is. That number does not exist as far as I know, and I cannot produce it alone. Post your labels and I will compute it and report it here.

Disclosure: the tool these came from is a project of mine. I am not linking it because it is not the point of this post.

(English is not my first language, I used an LLM to translate and tidy this text. The data and the analysis are mine.)

https://therapistrates.org tracks what insurers and platforms (Headway, Alma, Rula, Grow Therapy, etc.) actually reimburse for psychotherapy sessions. These rates are contractually confidential, so the data is crowd-sourced from therapist reports, with every row linked back to its primary source.

Raw JSON: https://therapistrates.org/data/rates.json (77 rows: platform, payer, state, license level, CPT code, rate, effective date, source link, verified flag). Companion ownership registry of who owns each platform: https://therapistrates.org/data/owners.json

Why it matters: this secrecy lands on patients. The same 53-minute session (CPT 90837) pays anywhere from $39 to $220 depending on payer and state, and when rates are that low and that opaque, therapists quietly leave insurance networks. Patients inherit the fallout: “ghost network” directories full of therapists who no longer take their plan, months-long waits, sessions quietly shortened from 60 minutes to 45, and full out-of-pocket bills for care their insurance nominally covers. In one sourced case an insurer paid a middleman platform $213.07 for a session while the treating clinician received $101.20 — a spread the patient never sees. There’s no official public source for any of these numbers; price transparency rules don’t reach behavioral health middleman arrangements.

Google outbid Mercor.

I’m surprised that it’s only worth 10 million!!

Disclosure: I run the site this is hosted on (alwayshave.fun, a trail-conditions site). No ads on the data pages, no signup, no paid tier — the files are static CSV/JSON on a CDN and the license is CC BY 4.0.

What it is: the federal NIFC/WFIGS Incident Locations feed publishes a current snapshot of active wildfires and overwrites it. Acreage and containment for a given fire on a given past day aren’t in it — once the number changes, the old one is gone. My pipeline was already reading that feed every 30 minutes for a different reason, so I started keeping the last read of each UTC day. That gives the growth curve the snapshot implies but never shows: how fast a fire ran, which day it blew up, when containment actually started moving.

Scope: every incident of 1,000+ acres in NV, UT, AZ, CO and CA.

Honest about the size — the daily record starts 2026-08-09, so right now it’s 39 incidents / 309 daily readings, with a multi-day curve on 38 of them. It grows by one row per active incident per day and incidents stay in the file permanently once they enter, including after they drop off the active feed.

• growth-history.csv — one row per incident per day: https://alwayshave.fun/data/fires/growth-history.csv
• archive.json — same data nested by incident: https://alwayshave.fun/data/fires/archive.json
• incidents.json — current read: https://alwayshave.fun/data/fires/incidents.json
• Columns, caveats and license: https://alwayshave.fun/data

Columns: date, incident_slug, incident_name, state, acres, containment_pct, cause, discovered, lat, lng.

Caveats, because they matter for anything you’d do with this:

• Acreage sometimes falls when a perimeter is remapped. Those revisions are kept as read, not smoothed.
• When an incident drops off the active feed, the file records only that NIFC stopped listing it. The feed doesn’t say whether a fire was contained or declared out, and I don’t guess.
• containment_pct is empty when the feed reported no value — never zero-filled.
• It’s exactly as accurate as the upstream feed; nothing here is reconciled against ground truth.

Original source (please cite it too if you use the raw fields): NIFC/WFIGS Incident Locations, https://data-nifc.opendata.arcgis.com/ — US interagency, public domain. The CC BY 4.0 here covers the compilation (the daily record), not the upstream feed.

Two other files on the same page, in case they’re more useful to someone than the fire data:

• Trailhead monthly climate normals, 2015–2024 (normals.csv, 552 rows) — avg high, avg low, wet-day count by month for 46 trailheads, computed from ERA5 at the trail’s own coordinates rather than the nearest town, which is often several thousand feet lower and a different regime.
• Live trail conditions (trails-index.json) — weather, AQI, fire proximity, river flow, refreshed every 30 min, each value carrying its own timestamp and source, and reported as missing rather than backfilled when a fetch fails.

Happy to add fields or a different export format if someone actually wants one.

I work with Streams Charts and we’ve just released v2 of our livestreaming API.

The main problem we’re trying to solve is fragmentation.

Twitch, YouTube, Kick and other livestreaming platforms don’t naturally give you one consistent dataset to work with, so cross-platform analysis often turns into maintaining separate integrations and mapping fields before you can even start comparing anything.

Streams Charts API now exposes channels, streams, games, lists and live snapshots from 9 platforms through one schema:

Twitch, YouTube, Kick, Rumble, SOOP Korea, CHZZK, NimoTV, Bigo Live and SteamTV.

There’s also a free request if anyone wants to inspect the output first: Top 100 Twitch channels, last 7 days, 0 credits, no card.

I’d genuinely be interested in feedback from people working with external datasets: which fields or delivery options matter most to you?

What it is: every date in 2026 and 2027 evaluated against the classical Hindu electional-astrology ruleset, for eight life events (marriage, griha pravesh, vehicle purchase, property, business, signing, travel, general).

• muhurat-2026: 1,291 dates
• muhurat-2027: 1,324 dates
• CSV and JSON, both years: https://bela.so/datasets/

The part that might be useful beyond the religious use case: each record carries the per-rule breakdown, not just a score. So for any date you can see which classical screen it passed and which it failed — tithi fitness, nakshatra suitability, yoga exclusions, panchaka, prohibited months, and so on. It’s a labelled ruleset-evaluation dataset as much as a calendar.

How it was computed: Swiss Ephemeris (full DE-series files), Lahiri/Chitrapaksha ayanamsa, mean nodes, drik-ganit — true solar/lunar positions rather than the mean-motion tables a lot of published almanacs still use. Deterministic: same input, same output, and the same engine version reproduces the files byte for byte. No language model touches any number in there. Method is written up at https://bela.so/methodology/ if you want to check the approach before trusting the data.

Caveats, so nobody gets surprised:

• Ayanamsa is a choice, not a fact. These are Lahiri. Raman or KP would shift every boundary by a few arcminutes, which moves some date boundaries.
• Times are computed per-city from local sunrise. The dataset ships a reference set of cities; it is not every town on earth.
• “Auspicious” here means “passes classical rule X” and nothing more. The rules are the object of study; I’m not making a claim about outcomes.

Happy to answer methodology questions or add fields if there’s something obvious missing.

Disclosure: this is my own project – I built and maintain it. [self-promotion]

What it is: AfrPowerOS is an open, machine-readable tracker of Africa’s civilian

nuclear-energy programs – 20 countries so far (Rwanda, Kenya, Ghana, Egypt, South

Africa, Uganda, Tanzania, Nigeria, Zambia, Morocco, Algeria, Ethiopia, Sudan,

Tunisia, Zimbabwe, Senegal, Mali, Niger, Eswatini, DR Congo).

Per country: programme phase, IAEA milestones status, regulator, implementing

agency, planned capacity, vendors, agreements, research reactors, and key events.

Why it’s trustworthy, per record:

– Every record carries a confidence label (Verified / Inference / Speculation /

Unverified) and every fact has source URLs (IAEA, government, regulators, media).

– Schema-validated: python3 scripts/validate.py (no dependencies).

– Data corrections are welcome via issues/PRs – errors are expected, this is an

early-stage community dataset.

I spent the last year tracking public GitHub activity across 4,200+ startup orgs and backtesting whether engineering acceleration precedes fundraise announcements. The result is a dataset of 219 documented fundraises paired with the GitHub activity metrics observed in the weeks before each announcement.

What’s in it: for each fundraise event, commit velocity over trailing 14-day windows, distinct contributor counts over 30-day windows, new public repo creation, sector classification, funding stage, and the lead time between signal and announcement (21-47 days in the cases where the pattern fired).

Dataset (Zenodo, CC BY 4.0): https://doi.org/10.5281/zenodo.19650920

Methodology preprint (SSRN): https://doi.org/10.2139/ssrn.6606558

Honest caveats: roughly 23% false-positive rate (acceleration sometimes means an enterprise deal or open-source push rather than a round), stealth companies with no public repos are invisible to this approach, and AI-heavy startups are noisy because model releases create commit spikes.

Everything comes from the public GitHub REST API v3, no scraping or private data. Happy to answer questions about the panel construction or backtest design.

The SGC.gov.co site claims it has an open data feed for earthquake data but I’ve been unable to find it. Anyone know where it is?

Dataset: https://zenodo.org/records/21484806

Disclosure first, because rule 1: I used this dataset to build a free iOS app, so I am not a neutral party here. Posting it because the dataset is genuinely good and I could not find it discussed on this sub.

Italian law requires every fuel station operator to file its prices with the Ministry of Enterprise, and the Ministry republishes the whole lot daily under IODL 2.0. Around 23,955 stations and roughly 93,000 prices, split across a price file and a station registry that carries address, brand and a self service flag.

The part I find unusual is that every individual price carries the timestamp of when that operator filed it. Most national fuel feeds I have looked at hand you a number and tell you nothing about its age. Here you can actually measure it: the median price is one day old, 71.8% are under 24 hours, 93.3% under three days, and 0.6% are more than a month old. That last sliver matters more than its size suggests, because pump prices drift upward, so a station that quietly stops filing keeps an old low number and floats straight to the top of any cheapest-first sort.

One warning if you go to parse it. The file is pipe delimited and does not escape pipes, so 106 rows carry a literal pipe inside a field. There are also 2,466 unbalanced double quotes sitting in company names, which means any reader treating the quote character as an enclosure will silently merge rows and hand you no error at all. I gave up and split on raw pipes without touching quotes. Worth knowing that the values are not sanity checked either: diesel gets filed at €0.123 and at €8.888, about 74 rows a day.

Does anyone know of another country publishing fuel prices at station level with a per-station filing timestamp? I have been through the French and Spanish feeds and both are day resolution at best, which is enough to sort but not enough to tell a driver whether to trust a number.
