The core promise of P2E was that players could - through gameplay and engagement - earn actual real world cash. In broad sense, this isn’t exactly new: things like gold farming, account boosting, eSports tournaments, and user-generated content… ## [Skill Ratings and Matchmaking, Part 1](https://kalifi.org/2026/02/skill-ratings.html) _2026-02-17 · Kari Silvennoinen · Kari Silvennoinen_ As multiplayer games grew in popularity, matchmaking - the backend machinery that decides who plays with whom - became far more noticeable. Back in the old days of lobbies, people more or less randomly piled together to play a game. However, people vary in skill and experience so wouldn’t it make sense to group people of equal skill to play together so that everyone can have a good time and not… ## [Using Steam’s Basic Usage Statistics to Measure Staying Power of Games](https://kalifi.org/2026/02/steambubbles.html) _2026-02-10 · Kari Silvennoinen · Kari Silvennoinen_ A long time ago I saw a presentation by Eric Seufert on Using (Free!) App Annie data to optimize your next game \[1\] . The idea was to do market research by taking the daily iOS Top Grossing chart positions of games and then do a linear regression of them and so filter down to games that have a positive coefficient over time. It’s really rough but does give some indication about games’ life cycles… ## [The Metaverse Can Not Happen](https://kalifi.org/2026/02/metaverse.html) _2026-02-04 · Kari Silvennoinen · Kari Silvennoinen_ Fortunately, the Metaverse boom seems to have mostly blown over by now, entirely enclipsed by the AI one. However, in the last five years, metaverse seemed to ride the hype cycle with cryptocurrencies, VR , NFT s, and Fornite and Roblox . The latter were definitely the technology triggers for the hype, the building blocks for the promised evolution of virtual worlds. For a good look of the peak of… ## [Revisiting the Million Ways to Markup Your Content](https://kalifi.org/2026/02/revisiting-million-ways-to-markup.html) _2026-02-03 · Kari Silvennoinen · Kari Silvennoinen_ Ten years ago, I wrote about The Million Ways to Markup Your Content , where I covered the then main ways (HTML5, Microdata, Microformats, OGP , JSON-LD ) to mark up one’s content for the semantic web , or more accurately for the search engines. When I last year moved my blog to Eleventy , I wrote my layouts from scratch and left most of the semantic markup to the floor for a couple of reasons.… ## [Verokuitti ja sen laskentaperusteet](https://kalifi.org/2026/01/verokuitti.html) _2026-01-31 · Kari Silvennoinen · Kari Silvennoinen_ Vuonna 2011 tein yhdessä parin kaverin kanssa harrasteprojektina Verokuitti -palvelun, jossa käyttäjä kykeni tutkimaan valtion budjettia syöttämällä vuositulonsa ja sivu visualisoi valtion menojen osuuden tälle käyttäjälle kauppakuitin muodossa. Palvelu voitti 2011 Apps4Finland-gaalassa Helsingin Sanomien erikoispalkinnon vuoden parhaasta tietojournalismista. Seuraavana vuonna se oli ehdolla… ## [The Updated Weblog Is Go](https://kalifi.org/2025/05/updated-weblog-is-go.html) _2025-05-12 · Kari Silvennoinen · Kari Silvennoinen_ Welcome to the 5th edition of this web log! For the past decade or so, this website was built with Jekyll . However, in the past few years my hodge podge of an asset pipeline built on Gulp meant that publishing anything started to become very difficult. Today, this website is built using Eleventy \[1\] , switching Jekyll’s Ruby to more web native Javascript. The main user facing changes are sharper…
