Re:Jev Can't Be Calibrated on Wednesday September 23, 2026 @12:06PM (#49818191)
I’m using Jev to classify a blob of text I see in browser with an extension. Calibrated? No. But it’s handy enough. If a large blob of text is likely AI generated, I’m very likely to skip it

Show HN: Sniffslop – browser extension to classify text using Jev

https://github.com/kmcheung12/sniffslop/

A browser extension to let you define any question to ask in a webpage. I default it to identify AI written texts. It extract texts element under cursor send to Jev for classification. It comes with all the caveats of Jev. Its classification is in no way an objective truth.Use your own API key at your own risk. I don't collect any info. Only network requests are to typesafe. For me 100 requests...

Thank you for all the explanations. I think I have better understanding now. Another question, at what scale (in terms of number of services, and maybe throughput? what other dimensions?) should we start considering using temporal?

Re:Temporal raises $550M at a $12.55B valuation on Monday September 14, 2026 @10:16AM (#49697277)
Can someone shed some lights on what temporal does? Their blog says [1]

Durable Execution offers three key benefits:

    It improves application reliability by providing fault tolerance.
    It simplifies code by allowing it to focus on the goal instead of potential problems.
    It accelerates development by eliminating the need to write complex error-handling logic.
So... like exception handling? or something like erlang's let it crash mantra?

Why is it such a big deal? Genuine question, not trying to be snarky

Hey thanks for checking it out! Really glad the site has more audience than me and my son only and appreciate the feedback!

Mind if I ask which mode were you playing? Was it "Find a country" or "Guess a country"? It might be due to the countries being too small. I maintain a separate small countries list [1] from the bigger ones [2]

[1] https://github.com/kmcheung12/geo-dude/blob/main/public/data...

[2] https://github.com/kmcheung12/geo-dude/blob/main/public/data...

I didn't come up with a good way to show small countries so it is the way it is. Would love to hear suggestion though!

Re:Show HN: Learn Flags Quiz on Wednesday August 19, 2026 @02:44AM (#49357768)
If you read this message, can you provide more context please? Are you choosing the "Name the country" mode with question from "Same continent". It might be that south america has only 13 countries in my database, so it appears to be repeated.

I just turned the repo public for your reference.

Country list at https://github.com/kmcheung12/geo-dude/blob/main/server/coun...

Picking a question from a continent is shuffle and then pick question per round, so "pick without replacement" https://github.com/kmcheung12/geo-dude/blob/main/server/inde...

Re:Show HN: My local climbing gym from photogrammetry on Tuesday August 11, 2026 @03:36AM (#49254612)
Solid feedback, thanks!

1. is very doable. My local gym uses an app to manage monthly leaderboard already and people seem to like it. There is a friendly rivalry in my local gym where people "fight" for the top spots

2. A lot can be done from the helping beginner angle. A coach told me he wishes to show hip placement and movement to young climbers, as it is easier to show than to tell an 8yo. I thought of doing inverse kinematics from holds to resolve body positions, so I get beta (sequence of moves) for each problem right away. Too hard, don't know if it is solvable.

A bit tangential, I think in theory the climbing wall with a set of problems is itself an identifiable code. We might get rid of the QR code too. I can create an index of visual features that resolves to a camera position, raycast from camera position to narrow down to maybe 3-5 problems, and select videos from there. But I digress.

Re:Show HN: My local climbing gym from photogrammetry on Tuesday August 11, 2026 @03:18AM (#49254481)
On route rotation, maybe the gym will be responsible for uploading the scan. My local gym uses an app to manage route. People view what route is available on a wall. It is just a label saying "red is a V4", no photos, and every month there is a leaderboard. People apparently use it. And occasionally people share their beta there.

For outdoor problems, I imagine it will be more like a map, and recording be taken with a drone. This is in contrast to the climbing magazine with plain photos of route.

I also think the usefulness decline as climbing ability increase. At the end of the day, climber just want to climb. But maybe there is some strava angle I can explore.

Appreciate your feedback, thank you!

Climbing gym photogrammetry. My idea is that route and climb recordings is best recorded against a 3D climbing gym model, rather than a plan video, and technology has gotten good enough to do with a regular phone.

As a climber myself, to climb effectively, one has to review their own climb, and with other people. 4D video, body positions across time, is very helpful in improving climbing. I managed to get a reasonable result (far from good) from one video, rather requiring multiple camera angles.

Haven't gotten to monetization yet, but I am enjoying every moment of making it.
