         | 
         | For example I filtered down to "United Kingdom" and then "bass"

         | 
         | Also if possible to apply the country filter within the search

         | country, select that, then go back to my search.
         | 
         | When clearing my search of "Bass" in the example above, it

       | I would say it combines the best parts of Duolingo and Anki. Anki
       | is great for memorizing words, but you don't see the words in the
       | context of novel sentences. Duolingo is great for exposure to new
       | sentences, but it's oriented around "lessons" and SRS is an

       | slowly.)
       | 
       | Had to do quite a bit to get it to work well.
       | 
       | 1. At first you would think that if you know all the words in a
       | sentence, that should be enough to understand the sentence. But
       | it doesn't work like that. For starters, words can have multiple
       | meanings. The french word "bois" can mean "(you) drink" or
       | "wood". You want to learn these separately. I trained an NLP
       | model (a gemma3 finetune) that I use to understand the manner
       | each word is used in each sentence:
       | https://huggingface.co/collections/anchpop/lexide-nlp-models
       | 
       | 2. Even then, what about a sentence like "you'd better not"? Even
       | if you know the words "you" "had" "better" and "not", you still
       | won't really get this. So I use the wiktionary "multiword terms"
       | category for each language to get a huge list of terms like "'d
       | better" , "you better believe it", etc, and teach these in
       | addition to individual words. And then I only show sentences
       | where you know all the individual words as well as all the terms.

       | 
       | https://michellepellon.com/portfolio/nfl-game-predictions
       | 
       | # What's under the hood today
       | 
       | ELO translated to the NFL with margin-of-victory adjustments, a
       | modest home-field term, and week-to-week recency weighting.
       | 
       | Post-hoc calibration with isotonic regression so 70% predictions
       | land near 0.70 empirically.
       | 
       | Monte Carlo to roll games forward for distributions on weekly win
       | odds and season outcomes, plus basic reliability/Brier/log-loss
       | tracking.
       | 
       | # Where I'm taking it (ensemble ideas)
       | 
       | Blend a few complementary signals: (1) pure ELO strength; (2)
       | schedule-adjusted EPA/Success Rate features; (3) injury/QB
       | continuity and rest/travel effects; (4) a small "market prior"
       | from closing lines; (5) weather/play style pace features.
       | 
       | Combine via a simple stacked model (regularized logistic,
       | isotonic on top), or a Bayesian hierarchical model that lets team
       | effects evolve with partial pooling.
       | 
       | Separate models for win prob vs. expected margin, then reconcile
       | with a consistent link so the two don't disagree.
       | 
       | Emphasis on calibration over leaderboard-chasing: reliability
       | diagrams, ECE, PIT histograms, and backtests that penalize regime
       | drift.
       | 
       | # Why I'm doing it
       | 
       | It's a sandbox to teach myself Monte Carlo and ELO end-to-end--
       | data ingest - feature plumbing - simulation - calibration - eval
       | --on a domain with immediate feedback every week.

       | # How this connects to my day job (healthcare ops)
       | 
       | I work at BlueSprig, running ~150 ABA therapy clinics. I'm
       | exploring whether ELO-like ideas can augment ops decisions:
       | 
       | "Strength" ratings for clinics, care teams, or scheduling
       | templates based on outcome deltas and throughput (margin-of-
       | victory [?] effect size/efficiency).
       | 
       | Opponent/schedule [?] case-mix, payer mix, staffing constraints,
       | geography.
       | 
       | Monte Carlo for expansion planning (new-site ramp curves),
       | capacity/OT forecasting, and risk-adjusted outcome monitoring
       | with calibration so probabilities mean something.
       | 
       | Guardrails for fairness and interpretability so ratings don't
       | become blunt scorecards.
       |

       | LINOG.ph is a live earthquake tracker for the Philippines.

       | The Philippines deals with thousands of earthquakes a year.
       | Whenever the government volcanology and seismology department

       | 
       | When a major earthquake happens, a huge number of people try to
       | visit the site, causing downtime for up to an hour.
       | 
       | LINOG.ph caches earthquake data from the official government
       | website and the U.S. Geological Survey site, and makes them
       | highly available to the public.
       | 
       | I built this after seeing friends and family donating and
       | providing support for affected families after a major earthquake
       | in Cebu. This was my way of helping out.
       | 
       | Two super typhoons have hit the Philippines in the past two
