Treasure Peak
my story đ
đ°ď¸ A long long time ago I played a game on our family PC called Treasure Mountain. A reviewer from that era gave it a thumbs up, claiming that âchildren will be captivated by the game's vibrant graphics...They will spend many hours solving puzzles, doing math problems, and looking for hidden treasures-- sharpening their math skills without even realizing it.â That was certainly true for me!
Fast forward to modern day Austin when my daughter asked me to set her up with some math games on a computer. We tried some of the available free games, but none of them were sufficiently mathy.
The good news: a bit of googling and I discovered my O.G. game could be played online through an emulator.
The great news: she was immediately into it! However, I was dissatisfied because this version surrounded the game with distracting ads (no shade at the business model).
The best news: itâs 2026, so this parent simply vibe coded a version with all the same features and gameplay + no ads, but worse graphics. I present to you Treasure Peak. My daughter likes it just as much.

Words with spaces. âEnglish is full of two- and three-word phrases that function as single semantic units effectively âwordsâ but because theyâre not fused into one orthographic word, theyâre invisible to dictionaries and underappreciated as vocabulary.â The author built a slider showing how many everyday compounds never make it into traditional dictionaries, even when they clearly name a thing. ~ learn more

Austin reviews âunusualâ $25 million Long Center contract over arts grant fees and oversight. âAustin Currentâs review of the contract raised questions about how much money the city is paying for specific services. Some of the hourly rates listed in the agreement include: $250 an hour to retrieve data for the city; $250 an hour to train panelists how to judge grant applications; $87 an hour to pay panelists who review the grants; and $54 an hour for customer service.â My read is that those are expensive but not wildly crazy. Iâve seen commercial contracts with similar prices. Is there someone out there who expects government negotiators to get a good deal on procurement? ~ learn more

Connecting AI is cheap. âConnecting things to our AI engines is cheap, and getting cheaper.â The post argues the bubble comparisons to railroads and telecom miss the key point: once the model exists, adding new use cases looks more like copying software than laying track. ~ learn more
Plinyâs jailbreaking is so good that frontier labs specifically train on his repo. Because he knows this, he is able to add backdoors to the newest models. Daniel Blank argues Plinyâs jailbreaks are not a sideshow, they are training data that shapes the next generation of models, including weird second-order effects like data poisoning. ~ learn more

DoorDashâs real AI advantage. In response to a viral AI doomer article, Stratechery went town on their silly example of Doordash being an AI-loser. âDoorDash not only has the most restaurant data, but also exclusive data in terms of customer order history, delivery routing, etc. All of this can be leveraged to not only make a better product but also in advertising.â The article argues that fears about DoorDashâs doom at AIâs hands miss the deeper moat: unique operational data, real-world workflows, and powerful network effects. ~ learn more

Does Amazon illegally price fix? âYesterday, California Attorney General Rob Bonta filed for an immediate halt to what he says is a widespread price-fixing scheme run by the largest online retailer in America, Amazon.â The piece argues Amazon leverages the Buy Box and vendor pressure so prices rise not only on Amazon, but across other retailers too. The core issue is that Amazon will lower its prices automatically to match competitors, or else suppress merchant listings. This argument seems a bit twisted but may not be totally wrong. Next up, a California judge will get to rule on the issue. ~ learn more
AI customer service on United. âhaha no maâam but I get that a lotâ Grace called United after a snowstorm cancellation and got rebooked in about 20 minutes by a voice that sounded very AI, down to doing a quick 228*6647 calculation on request. ~ learn more
