About 8 months ago I deliberately obfuscated some merge sort code to give to my software engineering students to make them upset. :) I munged it up pretty good, changing the structure, making the variable names completely misleading, destroying the symmetry, etc. Out of curiosity, I fed it into ChatGPT and it had it figured out in zero seconds.
I've gotten used pixels off of ebay more than once and never had a problem. I feel like if it was that simple swappa.com wouldn't exist though. Maybe I've been lucky?
Same here, I bought my current smartphone, a Pixel 6, two or three years ago for 200 dollars on eBay, and it arrived in pristine condition. Super small bump on one of the frame edges, not a single scratch on the display though now there are many, of course, I'm not that careful and the phone is cheap enough not to be too upset.
I generally trust private sellers a lot more than professional ones, if you vet them well enough (check their page, check their reviews, check their other listings), the chance that you'll get a good deal on a device in the condition described. The incentive to gain a profit is a whole lot lower, a commercial seller has to make sure they're the winner in some way during a transaction, they have bills, staff and assets. A private person is often happy to just get rid of the phone, as it would usually rot in the old phone drawer, until it eventually ends up in an e-waste bin a decade later when they clean out. Getting a little money back is already a win. Surprisingly, I've never had a bad experience. I presume there's also buyer protection, but I'm hoping I never have to use it.
I've also had good experiences on eBay. Buyers can leave bad reviews for anything so good reviews are a strong indicator. (That said, there are plenty of "genuine" laptop batteries for $15 from high-scoring sellers.)
I feel like eBay put a lot of work into creating a competitive marketplace where honesty was rewarded, and it basically works well but they got an unsavory reputation anyways. Then Amazon tried to hide that complexity from the end user and buyers just get burned. Maybe Swappa is trying to go the Amazon route? I do not think there are real shortcuts here. Either the marketplace needs to vet sellers manually, or offer a competitive, transparent reputation system like eBay.
I think eBay's larger volume makes it easier to find a seller that will go through the "infeasible" trouble of sorting OEM-unlocked devices. I very recently switched to Graphene and nearly purchased from a listing that had similar "may or may not be OEM locked" language before finding one that promised it was unlocked.
1000 in 10,000 mammograms come back positive by human radiologist.
50 in 10,000 are actually cancer.
It is interesting that the article did not say what the positive rate of detection was, or the false positive rate.
Either way, of course, The next step would be to have a human eyeball it. Probably in India or China or some other low-cost provider. Only the wealthiest can afford the immense salary of a US-based radiologist.
Fun fact: I know a radiologist and her visual acuity is freaky good. I doubt that AI will be able to beat her unless they force it into a multi-day marathon.
Kids growing up with PCs and learning by tinkering and making crap code reminds me of the Go (game) proverb: "Lose your first 50 games as quickly as possible." That time was so valuable.
Or, as I tell my students, "Every failure is a growth opportunity." I let them resubmit corrected projects for points, too. I'm desperate for them to get the reps in that they'd normally have had as juniors in the field.
And, arguably, still useful to all.
