A bot that will minimize the expected number of (not yet seen) cards to draw to complete the hand the hand does reasonably well at deciding which card to draw or discard. The number of potential melds in a hand is small enough for modern hardware to completely enumerate, and you start the game with only 42 possible cards in the draw pile, with the number going down almost every turn, so the calculation is very feasible.

For knocking, a heuristic for how many turns vs. amount of deadwood (which should vary based on the undercut bonus you use) does "okay"; adding a bit of randomness should be done to prevent stronger players from being able to place a lower-bounds on your count may be a good idea.


When my oldest two kids were tweens, it seemed like the average age of first-cell-phone was about 10 in their social circles.

I didn't want to do that, but not being able to text also amounted to social exclusion, so I got them each a jmp.chat line and they could send and receive texts from the family computer.

Haven't had to do it for my youngest kid yet as the age that her friends are getting cell phones is much older (she's in 7th and less than half of her friends have a phone on them at all times -- though many have a phone to take when they e.g. go on bike rides).


Same here. Very few kids in my sons middle school class have gotten phones, most of his friends have not. Makes it a lot easier when they’re not a lone. I also see drastically fewer kids (and adults) on devices in restaurants which is encouraging.

"Open Standard" means "Anybody is allowed to buy it"

Anybody know how many students take CS 10 in a typical spring semester?

I believe it’s still a single section, so probably around 250 (at least that’s about what it was when I was there a long time ago). Compared to the 1000+ who take 61A.

So that's more than 10%, and (assuming the reporting is accurate) this was on an exam, not homework...

Or how many are normally caught cheating?

Did they use AI to detect AI using cheaters?


And if cheating was triggered using AI detectors, was it real?

AI detectors are pretty mid in practice - they tend to have a lot of false positives for "B" students who are okay, but can still be struggled to be more coherent than AIs are. There are some specific triggers that AIs are way more likely to do than students, but a lot of AI detectors will trigger on this "almost there, but you're still struggling" level of essay writing that might get a B, B-.

I could expect the same might be true for CS students even though I haven't seen how AI detectors work for CS/math homework.


You'd be amazed at how many students we know are obviously cheating because the logs reveal that they copy pasted a long, complete answer within seconds of opening a problem for the first time, full of sophisticated code constructs that we didn't teach them, and lot's of nicely formatted comments. Sometimes they even copy/paste the entire GPT output and then format it down.

This has been my wife’s experience as a college math professor. Instead of code it’s extremely formal problems with way more steps than the student normally performs using notation never taught in class.

It’s not that students didn’t cheat before, LLMs have just lowered the bar so far many can’t complete a live test in a class that requires effort.


When I was a section leader (not at Berkeley, though) we used MOSS: https://theory.stanford.edu/~aiken/moss/

It's not AI, its a deterministic program that analyzes compiled code for similarity.


I own a CRT and several playstation games. Many (most?) of the 3D games don't hold up that well. The aliasing artifacts are still quite visible and many games have occlusion bugs that TFA alludes to.

Why did I think the XA decompression happened in the CD-ROM unit rather than the SPU?

It does. The SPU only handles decoding and playback of ADPCM samples from its own memory and receives all CD audio from an I2S bus; the CD-ROM sector decoder chip handles XA-ADPCM decoding and resampling to 44.1 KHz internally, then sends the audio over I2S as if it were CD-DA. This is also why the SPU's ADPCM format is slightly different from XA-ADPCM (no interleaving and 5 filter coefficient presets rather than just the 4 used by XA-ADPCM and the older ADPCM format used on the SNES).

At a certain level of build quality the Mac has at many times in this century been a good value. Except maybe if you load it up with RAM and/or storage which always seems to have a much higher marginal cost than non-MAC hardware.

A couple of comments:

> But any instrument that’s not the piano or guitar can actually make micro-adjustments while playing a song

You can make micro adjustments on a guitar, but only to be sharper[1]

> But for now, one obvious advantage is that this allows us to do “real” glissandos, where the pitch smoothly transitions from one note to another

For a famous example of a "fake" glissando, the opening clarinet solo of Rhapsody in Blue, which, as typically performed, is rather smooth from D5 to C6[2]

You can make adjustments on a guitar to make a note flatter by pushing the neck/headstock forward, relaxing the strings slightly

The keys on my 35S, which superficially resemble the keys on my 11C have not been nearly as reliable; After just a couple of years of use, mine started missing presses on frequently used keys.

I salute you sir. Did you have a better solution for later versions?


cad/stl/cnc related files for 'automated assembly' via 3d printing pcb[1] / pick-n-place machine[2][3] would be nice.
