> I agree in that they are much more convenient for tourists and occasional users […]

I would argue that contactless debit/credit card or mobile wallet taps are substantially more convenient for tourists and occasional users – if you are fresh off the boat (or off the plane – for a more modern twist), not much can beat the convenience of turning up at the turnstile, tapping on and getting on with the trip on the local public transport network and tapping off at the end of the trip.

No need to look for a place that sells local rechargeable or disposable NFC cards, having to be aware of a low balance, looking for a place where the card can be topped up, actually top them up and stuff like that. For frequent travellers, it also entails having fewer non-portable mass transit payment cards to carry.

Bonus points: debit/credit card/mobile wallet payments also eliminate the problem of the discovery and consolidation of lost balances when a card gets lost, and it reduces the environment impact (manufacturing + energy consumed during the process) and the wastage (the disposal or, rather, the lack thereof) that disposable NFC cards inherently possess.

That is what Sydney (the one that is not in Canada) has done: they went straight from prepaid paper tickets to their own rechargeable Octopus/Oyster style cards (with the name also beginning with an «O» – Opal) followed by enabling debit/credit card (Visa/MC/AmEx) and mobile wallet NFC payments later within the larger metropolitan area public transport network on buses, ferries, trains and trams.

Convenience, as always and of course, comes at the expense of privacy, though.
Magnetic paper can't do computations, so these tickets are a storage medium only and as such can usually be trivially copied. That puts higher requirements on the backend's availability in order to prevent fraud.

Most people in Japan actually use (reloadable) IC cards, as far as I understand, and railways seem to be in progress of switching magnetic stripe tickets for QR code based ones: https://english.kyodonews.net/news/2024/05/362243d2c187-japa...
All those abstractions are necessary in order to do software engineering of real-world systems at scale.

No, they're not.
No. Because carriers are idiots.

The carriers require you to allow them to force a firmware upgrade on you. This kills your battery dead long before anything you would do on the device will.

Technically, however, 10 year battery life is generally unreasonable. Most batteries that exist self-discharge over 10 years. 5 years is doable, but requires quite solid engineering. 3 years is pretty reasonable for most things.

If you want 10 year lifetimes, I think you specifically need lithium thionyl chloride batteries.
Yeah, that's what I meant, sorry if that wasn't clear – open-loop payment card based systems make more sense for infrequent users and tourists for all the reasons you've mentioned; dedicated card purse-based systems can be better for regular commuters.

The thing about hypotheses is that they can be either true or false. And seeing NVDA triple in the past year, even while there are many people devoting their working lives just to do financial analysis of the stock, tells us the hypothesis is false.

Very interesting. It's difficult to get hard numbers. It depends a lot on the composition and the temperature, so I'm more optimistic about they lasting for a few millons years at burried at 15°C(60°F), but I agree they don't last forever

I guess they are. Look at this video https://www.youtube.com/watch?v=fjp6RHb7MtE the truck are huge, from time to time there appears a normal truck next to them and it looks like a toy truck. I think when abandonded they get filled with water, then with mud and decomposing plants, and then that will solidify and in the future they will have a huge "volvano caldera" but no volcano at the bottom. Also find the internal roads, cuts by explossions and other strange characterisitcs. The truck will have rot a long time ago and dissapeared, but they may find unusual levels of iron contamination in the parking lot.
I think Oyster cards are still stored-value based, but I suspect that either the backend servers and connections are now fast enough to poll pending top-ups in real time, or they just fan out the pending top up dataset to all turnstiles.

I remember using that feature in the SF bay area, and while it took a day for the top-up to actually propagate to all readers, it even worked on buses, so they must be uploading that data everywhere.

That type of connection needs to be there in any system that supports lost/stolen card value recovery, in any case, since that's how card block lists are distributed.

Getting <100% coverage means you have no idea what some of the code does when run in dumb, non-parallel mode. Thar be bugs!

And those bugs are easier to find than the ones that might still exist if you have 100% coverage.

No one ever anywhere (except for numerous strawmen) has claimed 100% coverage "will eliminate all bugs and produce the perfect software."

> This article is useless. Everybody knows that 100% code coverage doesn’t eliminate bugs.

A double-secret strawman is still a strawman, dude.

Program files from the 1980s. Operating system files from the 1970s.

Their timestamps don't show those ages, unfortunately, as they have been transferred from machine to machine and medium to medium over the decades.

Here's one of my own COBOL files:

0130* INSTALLATION. Giacomo Software, P.O. Box 584, Hamilton, 3300
0140
0150 DATE-WRITTEN. 29 MARCH 1984.

Would you believe that was from an 8080 disassembler written in COBOL? I suppose we did silly things like that because we could. And we used whatever it was that we happened to have on hand.

That's an immediate red flag that tells me:

2) She thinks this is a "simple job" (It never is, regardless of the business in question).

Probably because it's around the size of a credit card and has fake smart card contacts printed on it. That being said, I would probably get confused myself too.

There's people in the ecosystem doing good things, but wow been a decade now of ARM ecosystem forever being ever-so-close to doing the right thing & learning from the ways x86 is such an open interoperable healthy ecosystem (Intel wifi chips aside; even the "PCIe" ones no longer work in any other systems/aren't spec complaint).

So here we are a decade later & still ARM is good only in flagship (and 25% of mid-ranged) cell phones running vendor sdks and now some hyperscaler's servers, but literally no one else can use decent modern arm stuff without a bunch of fuss.

The size of the forests isn't really relevant; compared to lumber demand, they're mostly insignificant. Humans have never had a problem wiping out local forests.

What matters is how much wood a forest can produce per year, not how much has accumulated over the course of the past.

However that sort of question " isn’t it the case that Theravadan meditation practice went practically extinct" is a very theravada move as the "way (vada) of the elders (thera)" it always asks "is this modern buddhism really what the buddha taught" and that characteristic emphasis at the center distinguishes it from the mahayana
QR codes seem like a better ticket medium.

This is like a 100 bytes, a qr code can be over 2kb

This is a cheap plastic substrate with ink printing over the top. A qr code is just ink - or some other even cheaper printing process if you prefer.

This needs a specific ticket technology supplier over the next 10’s of years. QR codes can be drawn on screens or printed on paper and you can change suppliers for every component - from mobile phone apps to paper type to physical printer and reader devices - until your heart’s content over the next years. That flexibility can’t be underestimated in a space like public ticketing over decades.

Issuing replacement tickets needs physical presence to collect the ticket, vs qr code which can be emailed, sent on whatsapp, shared as a screenshot or photo if you need to, but of course you can still exchange physical paper qr codes if you prefer.

The rfid reader for these are cheap and durable, the optical reader for qr codes can be almost as cheap and almost as durable but not quite, the rfid wins this one point by a small margin.

Title is very misleading. I initially thought this is a high-tech prank.

TLDR: Not just any "New Yorkers", but specifically "customers who want to buy a propeller hat". And hats are dropped not "onto", but "somewhere on the sidewalk next to" these New Yorkers. And sure, this might be "using AI", but AI seems like an overkill to recognize that a person is standing longer than three seconds under the window.

So a guy sells hats by dropping them out of the window. Not sure why there are so many comments praising this. Is it because of the pun? Am I missing something?

> If [...] this paper was actually for an academic conference or journal, then yes! you have committed academic misconduct.

This is a surprising perspective given that in many ways I had the same conversation with chatgpt about my work that I might have had with a colleague or a spouse. The biggest difference is that chatgpt's suggested improvements weren't very good, and none of its suggestions ended up in the final text. Is it the product of plagerism?

I absolutely believe that ChatGPT is being overused in academia, just like stackoverflow is in professional programming. But I don't think we have any consensus as to where the line should be between "acceptable use" and plagerism. To me, banning the tool outright would be as silly as banning google search, banning calculators outright in schools or banning artists from using photoshop. (And yes, people made the same argument about photoshop when it was invented - that art made with it wasn't really art because the computer did all the heavy lifting.)

> Given that you didn't really dispute my point and rather attacked the grounds for it, and that you invented a false premise of your own (that calculator policies are a per-country thing ???)

Of course. The grounds for your argument is where it unraveled. You claimed that my teachers had the right calculator policy, but you didn't (and still don't) have enough information to make that claim because you don't know the policy my teachers had.

I would have told you if you asked, but you didn't. You simply went on the attack assuming you had all the facts. And now in this followup message, you have doubled down on your mistake.

For reference, of course the calculator policy at my Australian school in the 90s was different from yours. We generally weren't allowed calculators on the school grounds at all. That started to change right at the end of high school, when they started allowing calculators in class and non-graphing calculators in examinations. (They checked as we walked in the door). But for most of my grade school experience, calculators were banned.

I've tried to start meditating a couple of times in my life but every time after a couple of days instead of being introduced to gradual calm/bliss/joy/whatever I get met with an existential dread, sadness, anxiety, melancholy etc. I guess am naturally predisposed to those as well, much more than 'happy' feelings. I had to then take a week or even more to recover. I feel like you need to have your shit together so to speak before you try meditating or it might uncover some suppressed trauma or whatever it is. I must say though I am way more 'aware' of my body and emotions more than before, but the problem is they might not be pleasant. It is okay when the feeling is transitory but an existential dread which lasts for days or weeks feels impossible to shake off, it consumes your whole life. One day I hope to be able to swing the pendulum in the other way.

The MIFARE protocol (which Oyster cards use) takes 300ms to 500ms per tap. EMV (i.e. contactless cards) take ~500ms, which slows down normal walking speed.

The problem with QR codes is that they are read-only.

I don't know about Montreal, but Moscow public transport uses similar paper tickets, also Mifare Ultralight, except you can get them for different number of trips. When you use your ticket, the turnstile or validator would increment those one-way counters so that the next one would know how many trips you have left. You can't do that with a QR code without either the reader or the user's device having a persistent internet connection to some sort of central server that would keep track of all tickets, which is impractical.
Which is why I'll never support these short sighted "legalization" efforts. I see no utility in arresting someone for smoking a joint in their own home. Arming the government with yet another source of tax revenue is simply unacceptable
