The person who coined the term "prompt injection" has the same gripe, because the original term genuinely did mean an attack using untrusted user input, a la SQL injection. But it's been conflated with jailbreak attacks in general, muddying the term.

Example of a bona fide prompt injection: white text in the background of a resume PDF, attacking a job application portal that uses LLMs to filter applicants. No privilege escalation is involved to give the candidate top marks on their resume screening.

Whereas a non-prompt injection jailbreak would be bypassing a safety filter, such as how Morse code might get past the filter and allow a user to request other people's cryptocurrency be transfered away. This is more akin to finding a poorly-secured, public facing API and then exploiting it.

I'd like to draw a comparison: a cozy wood fire versus central heating. In the right time and place (eg camping in the woods), a wood fire is both very practical and very useful. Meanwhile, most homes built in the past 70+ years in the USA have central heating (or are somewhere that doesn't need heating at all) and the benefits are quite obvious: automatic temperature regulation, supplied by a utility, and low or no local emissions. And yet, there will still be rural homes that are heated exclusively by a wood stove, located in the middle of the living room, whose iron construction stores and radiates heat well after the fire has gone out.

Do I bemoan individual homes that use a wood fire? No, not really. The reality is that a grand, overwhelming majority of people don't have wood fires anymore. Even when air quality is poor, prohibiting wood fires in a few rural homes isn't exactly what would clear up the air.

Now, it would be a vastly different story if city-dwellers all had wood fires. When every home in a neighborhood is building and burning a wood fire, the results are disastrous: horrific PM2.5 in the air, soot coating everything, substantially reduced energy efficiency, and mass logging just to keep the wood supply. A mole-hill quickly becomes a mountain of problems when it's at scale.

So to that end, I would very much like to see commercial-scale AI reigned in, as the external costs have already gotten out of hand. What they have built is more correctly called a wildfire, not a wood fire. But where does that leave small-scale AI/LLM users? They can weigh the cost/benefits for themselves, provided that they don't harm other people or resources in the process.

But that brings us back to a cozy wood fire versus central heating: at small scale, a wood fire struggles to heat an entire modern American home (ie 2500 sq ft; or 232 sq m). Yet central heating does it with ease. Who then will be interested in this endeavor? Probably only those with a love for the camping aesthetic, and other enthusiasts.

At this point, it has become more clear what the utility of small LLM models is, and they do pale in comparison to larger LLM models. If small LLMs are what sensibly survives into the future, then that's essentially a cap on their capabilities, given a want to avoid burning the planet to run anything larger. The only way out would be for substantial developments in the energy efficiency of small LLM models, but that's not where the interest is.

No one is seeking to build a more efficient wood fire.

I don't disagree. But seeing as OP specifically asked for a word, I'm inclined to offer the most specific, most descriptive word I can muster that is germane to what they've described.

IMO, precision of language is paramount when it comes to addressing other people's problematic behavior, because it closes the door on excuses like "it's just a simple misunderstanding" or "that's just their opinion".

The most poignant example I've heard of are from parents that make absolutely certain that their children learn the proper names for their body parts. As in, not "hoo-hah" or "privates" but the actual, unambiguous clinical names. This is a marked improvement than the TV trope of "where on the doll did the bad man touch you".

financial philosophy

Surely this would just be economics, no? Especially as your question pertains to the money supply, which is squarely in the domain of macroeconomics.

how much money is there in total, in the world?

I can only summarize what my economics course at uni covered, but you'd have to start with defining what should be counted as money. Even if we looked at an isolated island nation, what is and isn't money is not readily apparent. If I write out a check/cheque drawn against my bank account, is that money? Can my cheque be circulated as if it were currency? How about a banknote against the gold reserves of a national bank or treasury? What if that banknote isn't directly redeemable for gold or anything, but is a floating currency? What if it's neither redeemable nor is managed as if a currency, and yet it is readily accepted by Canadians and has actual buying power at a national retail chain.

Then we get to second-order candidates that could be money (or not): goods and services, land and houses, ongoing businesses, these all have some value and are tradable. Are these money? Are they at least a store of value? If a company is incorporated and is imbued with some starting investment, and then grows that value through business operations, does that create money?

To deal with this messy reality, economists have multiple definitions for money supply, found here: https://en.wikipedia.org/wiki/Money_supply. If two people use differing definitions, then of course they'll conclude different values for the world's total money supply.

Then the bank owes $1.02B actually, while only having $1B on the account. So the total amount isn't zero, it's negative

Not correct, because: 1) this fails to account for the interest the bank can generate through re-lending the money, and 2) interest is not a front loaded charge but is an expense over time.

For #1, it would be some profligate mismanagement of money for a bank to just obtain a loan "for the lolz" and there would be some sort of plan to actually make it do work. In that sense, capital should be viewed as if it were a powderkeg: very capable if applied carefully, very dangerous if mishandled. As for whether or not a bank's future revenue can be immediately reflected on their books -- since the revenue is only theoretical yet the central bank loan is already a certainty -- that's a question for accountants.

For #2, the mistake is that interest -- although continually accruing, or by other terms -- is somehow entirely due at the very beginning, which is not how most loans are structured. At any given point in time, yes, the bank could have negative net value, but they could also have positive net value, depending on their cash inflows. And even with negative cash flow, accounts receivable could still boost their net value because future value is still value.

My recommendation would be to review some basics in economics or accountability, as these sorts of questions have been hashed out over the course of hundreds of years. And even when economic theories don't exactly describe this reality, they are still useful as models, which is still more rigorous an approach than divination.

An app...lique?

Sewing jokes aside, this would be a nightmare, where something as basic as a bandage requires an app to unlock the dispenser. Dead phone? I guess only death awaits...

Following along, in the hopes a material scientist will give a detailed description of what makes a good lube for human activities.

Some of the most impactful demonstrations of science are hands-on activities. After all, any sufficiently advanced science starts to look like magic, and a major objective of science museums is to disabuse people of that notion. That these demos seem to be child-oriented is simply a result of not assuming any background knowledge of the topic. But even adults might not know how a tumbler lock works, or that electricity follows all paths in inverse proportion to resistance. If something is rooted in natural phenomena, age is not a prerequisite to understanding.

As an adult, I personally enjoy science museums precisely because they're the polar opposite of technical papers and textbooks: an accessible and chill mood to learn about stuff I've seen but never paid much attention to. I'm not so vain to think that I can't learn something from a museum visit. In some sense, adults going to science museum is akin to edutainment, the genre on YouTube. Some museums even specifically have after-hours events so that adults can roam without children in the way.

Some might also call it "adult learning" or "continuing education", but whatever it is, it's enriching for individuals and families alike.

The brilliance of the McMaster-Carr website is best appreciated when viewed alongside the print version of the McMaster-Carr catalog. As a child, I literally grew up on that bright yellow book, since my parents used it as my booster seat for the kitchen table. It is a thick tome, second only to the thinner Grainger catalog, which became the next booster seat after a few years.

 

Background: I spent 40 minutes typing up a reply to a different post, but decided that it ran on for too long. I'll include it at the bottom, but I'm curious to know how much cash is still used in this country.

Certainly, a like-for-like Giro (Europe) system doesn't exist in the USA, with ACH, checks, and Zelle almost filling the void -- albeit incompletely -- which I suspect is responsible for the remaining cash utilization. But is that right? Is cash only used for when there isn't another option? Or is it a matter of consumer preference?

I can understand tipping in cash, or paying for a Craigslist purchase in cash. But maybe I'm missing another dimension? Do some folks pay rent in cash? Or taxes? I'm genuinely curious, but please make sure not to dox your finances in the comments.


My original comment

It's annoying when they get suspicious of a 25k USD withdrawal for instance (even if you managed to prove the purpose of such a withdrawal, it remains at the banks discretion whether they'll approve the transaction).

Let's break this down into multiple points:

  1. Suspiciousness of a 25k USD cash withdrawal
  2. Suspiciousness of a $25k USD electronic or check withdrawal
  3. Necessity to "prove the purpose" of any withdrawal
  4. Bank discretion and considerations regarding withdrawals
  5. Necessity of approval by the bank

I don't believe any of these five points are actually issues. As background, cash withdrawals within the USA are still very commonplace, as the country is fairly rather cash-centric when it comes to businesses, due in part to the lack of a system like Giro (Europe) that has both low, fixed transfer costs and can be sent or received by third-parties. The Federal Reserve's ACH system requires established relationships between accounts, whereas Giro does not. Debit card systems aren't a replacement for Giro either. Zelle (USA) is closer, but still isn't quite as full-fledged. Hence, businesses often deal in cash, pay employees in cash, and consumers pay other individuals in cash (eg buying an automobile).

To that end, for point 1, $25k as a cash withdrawal is not a daily occurrence but it does happen. I can't really think of ever paying for a private party used car by check, and such a cash-heavy transaction is often performed at the buyer's bank, so the seller is assured that the cash is good. In this setting, requesting to withdraw $25k cash is ordinary and mundane, if done very rarely. I doubt even prolific car buyers have this problem, but would be open to hearing evidence otherwise.

For point 2, electronic and check withdrawals have even less suspicion than cash, because they always leave traceable evidence. Money laundering concerns are reduced because the entire money trail can be reestablished later, whereas as cash can easily disappear or be "forgotten". To that end, the suspicion isn't about the cash amount but the source and destination. Even a $1 million check is not suspicious, if it's coming from a law firm's client account to a client's personal bank account. That is, again, a thing that happens fairly regularly. More down to earth, people can and do pay housing deposits by check, and property taxes are often drawn electronically. When one or both accounts to a transaction is prominent and established, there is a low probability of money laundering.

Point 3 is often though to be an issue, due to confusion about regulations for bank clerks on when to file a Suspicious Activity Report (SAR). Bank tellers are required to follow Federal Reserve regulations that aim to prevent abuse of the American financial system for money laundering. An SAR must be filled in whenever the teller: a) thinks money may be laundered, or b) the transaction is above the bank's or regulation's fixed amounts. The latter is often pegged at $10k, so this is where people think that it's disallowed to withdraw over $10k. This is not correct.

An SAR is something the teller fills in, and to do that, they might ask the customer some questions about the transaction. For the grand majority of people, the purpose is quite simple: cash purchase of a car, housing down payment, loan for a friend. Would the teller know if the customer is lying? Nope, not at all. But the SAR forms part of a trail of records, so that money laundering investigators can trace funds in the future. But note that the clerk can fill in an SAR for any type of transaction, including checks, and don't strictly need the customer's truthful answers (or any answers) anyway. An obligation to fill in an SAR does not prevent the transaction from going through. It's a speed bump, not a stop sign.

As for the actual stop signs, that's what point 4 covers. A bank obviously cannot allow a withdrawal if it would exceed the customer's balance, or if they don't physically have enough cash, or if the withdrawal is not authorized (ie not named on the account, or PIN not known), full stop. But other situations may arise where the withdrawal must be delayed, either for the bank's own convenience or because the account agreement specifically requires certain holdings times.

I quickly perused a random account agreement for Wells Fargo and the Available of Funds section describes that new accounts (less than 30 days old) will have elongated hold times for withdrawal against newly-deposited funds. This is applied in a first-in-first-out fashion, so only fully-draining the account would incur the longer hold time. In other cases, the bank may take more time but is required to inform you of that, and provide a definite date for when the withdrawal will clear. This verbiage does not distinguish cash vs non-cash, so they're within their rights to delay a check, as long as they obey their own agreement. If this is not tolerable, find a different bank.

Finally, this also gives us some insight into the default behavior for banks subject to Federal Reserve regulations, which is point 5. A bank may not deny a withdrawal of unencumbered, unheld funds (cash or otherwise), except when the bank has actual knowledge that the withdrawal definitely is for laundering. It is, after all, not their money: it belongs to the customer and they are just the regulated custodian of it. A bank can certainly advise a customer not to fall for a pig-butcherint scam, but they cannot block the customer from obtaining their own money back out. They can, as described earlier, apply a temporary, finite-time hold on the funds, but that's it.

To my knowledge, there is no Fed-regulated, FDIC/NCUA bank or credit union that requires pre-authorized approval to access a customer's own funds. I am open to hearing evidence to the contrary, but I don't believe such a thing exists. How would they even stay in business? To be clear from point 4, a bank can certainly ask for a few day's notice to prepare $50k in new $2 bills. But that's easy enough: just call the bank and verbally request the withdrawal, then collect it in-person days later.

Who is disadvantaged by this? Mostly money launderers and con artists trying to abscond with their scam proceeds. But I'd be remiss if I didn't also mention rich people that prefer to suddenly go on vacation and pay for everything in cash. But the system is designed to be no obstruction to those that plan ahead, or are dealing in such small amounts that it's not a big issue. Normal everyday people all share the costs of money laundering, so it's not fair to disadvantage them just so rich people and scammers aren't inconvenienced by their inability to plan ahead. They don't even have to plan ahead: just keep a few racks in the safe.

It is to me, frankly, a non-issue to withdraw money for me or anyone in the working or middle class, because the very issue of being "flagged by US banks" just rarely even a speed bump. And the rich folks have private banks that will gladly give them inordinate amounts of cash to spend.

What exactly is the problem here, specifically?

 

CLAUDE CODE JUST RICKROLLED ME. I'm working on a project where part of it will involve videos, and in building out the project it created a dummy page, with made up content (relevant to me!) with two video links pretending to be something else and BOTH WERE RICKROLLs.

Note: I'm using a broad definition of "programmer" to include HTML generation, and a broad definition of "humor" that includes Rickrolling. Together, I think this is appropriate for c/programmerhumor. Mods, please remove if not correct.

 

When I moved into my home many years ago, there was this lock-box mounted to the water main on the side of the house. I figured it was one of those used by real-estate agents to store the house key for viewings, but months passed and it still remained there. No one from my buyer's agent's office had a clue what this was, and the seller of the house had already moved out-of-state.

Recently, I had some plumbing work done, and that also included replacing the main water valve for the house, allowing this lock box to come free from the plumbing. Now inspecting it up close, and looking up the model online, I realized that it has an alphabet wheel and uses a three-letter combination.

As it happens, Thanksgiving weekend was upon me, and since I was bored, I figured I'd try all the possible combinations. Just 17,576 possible combinations, how bad could it be?

The most immediate problem was that due to being out in the elements, the dial did not turn easily. It would move, but was rather rough. And since the knob is only ~1 cm diameter, this is an incredibly un-ergonomic endeavor. I had to stop after the first 100 tries, due to the finger exhaustion.

Knowing this would be untenable for the long-run, I decided to build my way out of this problem. Since a combo lock involves making rotations that almost go all the way around, I drew inspiration from rotary telephone dials, where one's finger starts with the intended number and then swivels the dial around.

But whereas a rotary telephone dial only needs 10 positions, I needed to fit 26 positions, one for each letter. I decided on each hole being 17 mm to comfortably fit any of my fingers, but that also dictated the overall diameter of the wheel. But that's good, since a larger diameter wheel means more leverage to overcome the rough lock movement. It also happens to be that this wheel has a diameter of 180 mm, which is just enough to fit in the 200 mm bed of my 3d printer.

Using FreeCAD, I designed this wheel so that it fits around the splines of the lockbox dial, which held remarkably well. I had thought I would need Blu Tack or something to keep it together.

CAD design for lockbox dial wheel

Using this wheel, I'm able to "dial" combinations much quicker using one hand, while holding the lockbox with my other hand to press the lever down to test the combination. This should be good.

(fairly recent NewPipe user; ver 0.27.6)

Is there a way to hide particular live streams from showing up on the "What's New" tab? I found the option in Settings->Content->Fetch Channel Tabs which will prevent all live streams from showing in the tab. But I'm looking for an option to selective hide only certain live streams from the tab.

Some of my YouTube channels have 24/7 live streams (eg Arising Empire), which will always show at the top of the page. But I don't want to hide all live streams from all channels, since I do want to see if new live streams appear, usually ones that aren't 24/7.

Ideally, there'd be an option to long-press on a live stream in the tab, one which says "Hide From Feed", which would then prevent that particular stream ID from appearing in the feed for subsequent fetches.

From an implementation perspective, I imagine there would be some UI complexity in how to un-hide a stream, and to list out all hidden streams. If this isn't possible yet, I can try to draft a feature proposal later.

 

I'm trying to remind myself of a sort-of back-to-back chaise longue or sofa, probably from a scene on American TV or film -- possibly of the mid-century or modern style -- where I think two characters are having an informal business meeting. But the chaise longue itself is a single piece of furniture with two sides, such that each characters can stretch their legs while still being able to face each other for the meeting, with a short wall separating them.

That is to say, they are laying anti-parallel along the chaise longue, if that makes any sense. The picture here is the closest thing I could find on Google Images.

So my questions are: 1) what might this piece of furniture be called? A sofa, chaise longue, settee, something else? And 2) does anyone know of comparable pieces of furniture from TV or film? Additional photos might help me narrow my search, as I'm somewhat interested in trying to buy such a thing. Thanks!

EDIT 1: it looks like "tete a tete chair" is the best keyword so far for this piece of furniture

EDIT 2: the term "conversation chair" also yields a number of results, including a particular Second Empire style known as the "indiscreet", having room for three people!
