It’s available in various archives of the Toyota TechStream pre-2024 editions, in some sort of weird encrypted file format that can be trivially decrypted; I haven’t tried myself but the ECU I work with isn’t encrypted in-vehicle. I’ve spent five or six years in Ghidra with various hybrid Subaru-Toyota ECUs from 2013-2020 and I wonder what kind of source control practices result in the massive function spaghetti that must have produced in this SH-2A code; I can see where Toyota bolted their direct injection runloop into Subaru’s. So, yeah, if you’re curious, the firmware’s out there, if you’ve got a few years to spare and an absolutely ridiculous amount of patience (and a solid grasp of CAN bus messaging protocols, which you’ll need to identify code blocks and variables and such!)

“The Car Hacker’s Handbook” may be of interest as a first step review, but honestly I just dove in with Ghidra and just .. didn’t ever stop. YMMV :)

lol, thanks for the reply. Yes, I was thinking of looking at it, but your comment dissuaded me. Out of curiosity, did you try running ECU code through an LLM and asking questions of it, and, if so, how did that work out?

Does anyone know where one could obtain the firmware for this? It might be interesting to reverse engineer.

Why not just use SSE? https://developer.mozilla.org/en-US/docs/Web/API/Server-sent...

Do CDN, such as Cloudflare, support SSE? The last time I looked, they didn't, but maybe things have changed.

Similarly my hobby involving ship to shore cranes is going to be painful.

Seriously though they have a lot of stock in their warehouse. If this is already imported and paid for then it should be exempt right?

The page doesnt state what happens to foreign customers. Does the duty only apply for domestic buyers?

Out of curiosity, can you tell me more about your hobby that involves ship to shore cranes? Or, is this an indirect way of saying that your hobby involves transoceanic shipping? This is Hackernews, so it could plausibly be either.

Under $100: A used Instantpot, ideally the Duo Crisp if you can get one. The normal one can also make yogurt though, which might also be interesting. The great thing about these is that you don’t need to babysit them. Have a call or wanna go for a walk, and then eat? Just turn it on and come back anytime after it’s done. It will keep food warm until you turn it off. Bonus tip: Buy two and/or an air fryer to get more options, eg veggies in one and protein in the other.

Under $100 #2: Get a CGM for two weeks and find out what foods spike your blood sugar the most. Or what supplements can help keep it steady (eg vitamin B1, inositol, or Chromium). Say goodbye to food coma and likely improve your long term health.

Under $1000: Get a second freezer. From that point on you can buy frozen veggies etc during sales, and prep meals during the weekend, for the whole week. I don’t know how we got by with just one tiny freezer section in the fridge.

Are you in the US, and is it possible to obtain a CGM without a prescription?

Try talking to prospective customers. Understand what challenges they have and how you can address them.

Looks like googling "Harrah's data science" turns up a decent volume of articles. I won't link any in particular here because I haven't read any of them so I don't know which ones are good.
supahfly_remix · a year ago
Thanks! Yes, I was looking for recommended papers/info.

Probably here, but might be dry. https://link.springer.com/journal/10899

Thanks for the link. I wonder if this journal is constrained to observing gambling rather than doing experiments to trying to exacerbate it as Harrah's is doing: "The Journal of Gambling Studies is an interdisciplinary forum for research and discussion of the many and varied aspects of gambling behavior, both controlled and pathological. Coverage extends to the wide range of attendant and resultant problems, including alcoholism, suicide, crime, and a number of other mental health concerns."

My real wake-up call was the introductory class in my data science master's program. We spent a whole week learning about all the clever tricks Harrah's data scientists found to keep people in the gambling halls. The course's instructor really lionized Harrah's for doing this, and loved to talk about how much profit it made for the company.

For my part, I was horrified. I couldn't find a way to see some of these tricks the use as anything but a form of highly evolved confidence artistry. Legal con artistry, sure. But a legal scam is still a scam. Even if the people getting scammed never wise to the scam, it's still a scam.

The arguments about tax revenues and suchlike don't make me feel any better about it. All I see in their success is a demonstration that a great many people will happily turn a blind eye to abusive behavior if they believe they can materially benefit from doing so. And, of course, they never do, anyway. The promises of professional con artists that our communities will benefit if we grant them imprimatur for their operations turned out to also be a scam. Con artists pulling a con; quelle surprise!

This class sounds interesting. Where can I learn more about these techniques? (I'm curious, not planning on using them!)

FWIW, Pinboard's founder is still actively commenting (https://news.ycombinator.com/threads?id=idlewords) on HN as of 7 days ago.
