> Merchant agreements give the banks the power to forcibly remove funds from the merchant account on initiation of a chargeback.

Yes, and the amount will be booked right back if the chargeback is eventually lost by the issuer/won by the merchant acquirer. If that happens, it's up to the issuer to further claw it back from the cardholder (if permitted by rules and regulations) or write off the loss.

> There is zero chance American Express just picked up the six figures of chargebacks for the folks who put them in today.

Receiving an immediate credit is quite typical (and in some cases required by regulations), but receiving the money back is by no means an indication of having won the chargeback case. The keyword here is "provisional credit":

> When a chargeback is filed, the process to reach a final verdict can extend for weeks or even months. During this waiting period, issuing banks typically provide cardholders with a provisional credit covering the amount in question. If the resolution favors the merchant, this provisional credit can be easily reversed. (from [1])

All of this is usually also mentioned in the cardholder agreement and the "boilerplate" text you receive as part of a provisional credit from the issuing bank. Definitely both worth a read, especially when large amounts are involved.

> completely unsustainable for any decently sized chunk of the global population

I think the inherent critique in Solarpunk is that our current way of doing things is unsustainable for any decently-sized chunk of the global population - that climate change and general environmental collapse are signs that capitalism as we’ve run it so far cannot continue. If you take the critique at face value, it becomes less of a trade-off, because we don’t really have the thing we think we’re trading against: we’re not trading a successful capitalist future for a gamble on sustainability, we’re trying to find a successful future to begin with.

All of this is a fine thought experiment, but in practice there are physical limitations to digital processors that don’t seem to manifest in our brains (energy use in the ability to think vs running discrete commands)

It’s possible that we haven’t found a way to express your thinking function digitally, which I think is true, but I have a feeling that the complexity of thought requires the analog-ness of our brains.

> I'm a bit surprised there was no mention of semiconductors (mostly capacitors?) going bad on 1990's hard drives.

I don’t think any kind of capacitor is a semiconductor.
Everything gets captured by capital.. This aesthetic resonates the same with me. Its partly what drove me to join a startup to do global solar radiation forecasting as first employee. Burnt myself out over 4 years, but built platform that enabled higher penetration of solar pv power into grids all over the world, and was successful in this. I left due to burn out and realizing that most of the customers we would talk to about large scale solar utility sites that wanted integration with the data were basically banks/finance/insurance companies trying to return a better yield, they didn't care how. After I left got bought out by a risk management company.

Call me naive, but I went into it knowing solar power is _cheaper_, and the inability to measure how much solar energy was in an electricity network, and uncertainty about the generation were the main problems the startup was aiming to solve. The finance made it attractive to capital, I got that, partly why I was convinced it would succeed, but I underestimated how laser focused these groups are to "line go up". They would outsource everything because they were there as the money people, and have people in the meeting knowing just enough to gauge if project was on track for expectations of "line go up".

Problem being is that the margins aren't there. Everytime a solar panel is added to an electricity network, the life time ROI for ALL panels in the network goes down. This is due to pushing down the price of electricity during the day. Eg, when oversupply occurs in the middle of the day (and they don't store it cause X is cheaper), it causes electricity markets to drive prices down and even negative, meaning the return of possible life time generated power for each panel also gets reduced.

Saying all that, the adoption of renewables is growing at a rapid pace due to it being cheaper, but also slowed down by constant value extraction shenanigans.
Horray!

This is not really the case mentioned (not API design), but I somewhat often have an enum that is likely to be added to, but rarely (lots of code will have been written in the meantime) and I would like to update all the sites using it, or at least review them. Typically it looks something like this:

enum WidgetFlavor
{
Vanilla,
Chocolate,
Strawberry,

NumWidgetFlavors
};

And then wherever I have switch(widgetFlavor), include static_assert(NumWidgetFlavors==4). A bit jealous of rust's exhaustive enums/matches.

With contractors, I’d guess 40% or more. I’ve discovered things that are pretty shocking.

With employees, I agree it’s much lower, it’s mostly just lazy loafing that is harder to spot if the employer doesn’t have clear evidence of performance. The bigger issue for them are people who move away, lie and invent medical problems to avoid work rules.

The majority of my folks are in IT infrastructure and support. It’s pretty easy to spot on the operations side if you understand the tickets. The other side of the shop, who do more dev work relies on having good managers and leads. The documentation isn’t a fair evaluation— a single change may require weeks of work for a developer, so using counts isn’t fair unless you really understand the workflows. For those roles, hybrid makes hiding easier.

> What if a critical piece of the puzzle of brain aging has been hiding in plain sight? While neuroscience has long focused on proteins and DNA, a team of Stanford researchers dared to shift their gaze to sugars – specifically the complex sugar chains that cover all our cells like chain mail.. Shi’s project was the first to investigate how age affects its sugary armor – the glycocalyx.. “Modulating glycans has a major effect on the brain – both negatively in aging, when these sugars are lost, and positively, when they are restored,” Shi says. “This opens an entirely new avenue for treating brain aging and related diseases.”

Or maybe an attempt to accelerate a reduction of trust in the dollar? Any cryptocurrency in the strategic reserve is being purchase with dollars, which increases the number of dollars in circulation, and will also be directly inflationary (if it’s newly issued dollars) or increases the US debt (if those dollars are obtained by issuing debt, which classical macroeconomic theory suggests is also inflationary).

I've been using it on macOS for quite some time now, coming from Safari, and am really happy with it. I use homebrew like so:

brew upgrade librewolf --no-quarantine

I use Zoom Page WE to manage per page zoom levels, this alone was a game changer for me compared to Safari.

It bothers me a lot that you're complaining about downvotes when the comment you are replying to isn't even greyed out let alone flagged dead.

It bothers me a lot that you can't discuss something like this without turning it into personal attacks. People can't just have different preferences than you. No it has to be "elitists" with "stockholm syndrome". This kind of rhetoric is unbecoming of this forum and destroys amicable discussion.

Have you considered that maybe people use the command line because it is better for them, and they recommend it to others because in their view, you'll need it eventually so why not learn now?

You can visualise a git history with a gui tool while still learning the command line interface btw. They aren't mutually exclusive. Do you just use scratch too? Or are you one of those elitists using textual programming languages? Must be stockholm syndrome...

Money in university budgets is most certainly not fungible. Endowments are for the most part directed for specific uses and cannot be used outside of the restrictions. Education and General (E&G, terminology varies between institutions) includes tuition (only part of the yearly budget) and cannot be used for research. Unrestricted funds are as rare as hens teeth and doubly so outside upper admin.

The “color of money” is perhaps the most misunderstood aspect of university admin but explains so much about how things operate.

That’s a good rule of thumb, but it’s not infallible. In this case, the better question would be why the word “immigrant” is not mentioned even once.

I once submitted some code for review, in which the AI had inserted a recursive call to the same function being defined. The recursive call was completely unnecessary and completely nonsensical, but also not wrong per se - it just caused the function to repeat what it was doing. The code typechecked, the tests passed, and the line of code was easy to miss while doing a cursory read through the logic. I missed it, the code reviewer missed it, and eventually it merged to production.

Unfortunately there was one particular edge case which caused that recursive call to become an infinite loop, and I was extremely embarrassed seeing that "stack overflow" server error alert come through Slack afterward.

Couple do, though long term studies on a few are missing.

Well, you replace bricks every couple hundred years, but solar panels every 10–20, right? Also a 2000W solar panel is like $300 or something and it's half the size of a door.

Unless a building is crowd-funded by the future tenants with the promise of no electrical costs, and also the future tenants expect to live like 100 more years, I can't see how this could happen, short of the eradication of private property and the government constructing these things.

Yes, this is for floating point multiplies. But internally, the FPU uses x86 extended-precision numbers, 80-bit floats, with 64 bits of significand and 15 exponent bits. So the multiplier is dealing with 64-bit numbers, plus a few more bits to support rounding correctly.

i went to middle school starting in ‘98 (7th grade). I used a hand saw, glass cutter, sandblaster, and drill press. That was just a quarter. The second quarter we had home-ec. Stitched and baked and maybe something else. In shop I made a book shelf thing and a nameplate (sandblasted mirror)

In 9th grade I used a jointer and a band saw, built deep bookshelf out of poplar. In 10th grade I built a night stand (used shaper, Joiner, jointer, etc..)

The table saw was off limits in every class I remember, but most the other things were usable. With saw stops available, I think that reduces liability quite a bit.

Also in high school I did drafting and cad (2D and 3D).

Anyway, that was across 3 school districts in two states, and was as recent as 2003 - so it’s not like shop/industrial arts stopped being a thing 40 years ago.
> if you don't understand it fully, how can you say that it will look great to you, and that it will work?

Presumably, that simply reflects that a primary developer always has an advantage of having a more reliable understanding of a large code base - and the insights into the problem that come about during development challenges - than a reviewer of such code.

A lot of important bug subtle insights, many sub-verbal, into a problem come from going through the large and small challenges of creating something that solves it. Reviewers just don't get those insights as reliably.

Reviewers can't see all the subtle or non-obvious alternate paths or choices. They are less likely to independently identify subtle traps.
The rest of my infosec career is going to be me sharing my decisions and having them torn apart here by people far better and more experienced than me, but I could do worse. I appreciate every time you tell me I’m wrong, that’s how I get better.
I was going to suggest tempeh as well. It takes some practice and creativity to turn tempeh into interesting meals [1], but it makes the beans much easier to digest, and the tempeh adds extra dietary fiber, significantly increasing satiety (in my experience).

So what happens if we slow that flux? That's spread across the globe. What's the impact if those numbers are localized?

Radioactivity and tidal forces create a fixed amount a heat and that heat dissipates at a given rate, right? So what happens if we change that rate of dissipation/extraction?

No, I don't think laminar matroids are a subset of graphic matroids (nor vice versa).

I think laminar matroids occur fairly naturally in lots of places where a computer scientist would use a heap.

> Hierarchical or Nested Constraints:

> When problems involve hierarchical resource constraints—say, scheduling with nested deadlines or quotas that are imposed at different levels—a laminar family naturally describes these relationships. The corresponding laminar matroid models the “at most so many” restrictions on various overlapping (but nested) groups.

> Network Design and Resource Allocation:

> In network design or resource allocation, you may encounter situations where resources are grouped in a hierarchy (for example, a network might have capacities on various subnetworks that nest within one another). Laminar matroids capture this kind of structure.

One of my original motivating examples was something like this: suppose you have a compiler that's supposed to give good error messages. Now it gets input with mismatched parens like "a = (b * (c + d);"

Both "a = (b * c + d);" and "a = b * (c + d);" are ways to remove the fewest number of characters to get a well-balanced expression. Assume some other parts of your parser give you some weights to tell you which parens are less suspicious / more likely to be intended by the user. You want to select the subsequence of characters that has the highest total weight, or equivalently: delete the most suspicous parens only.

In any real world scenario, you would just use a normal heap to do this in O(n log n) time. But I was investigating whether we could do it in linear time, or prove that linear time ain't possible.

Well, I figured out that linear time is possible.

I'm actually working on writing it down and publishing it as a paper or at least blog post.

> I feel like Penrose presupposes the human mind is non computable.

He has been very clear in that he claims exactly that and that there is Quantum Mechanics (wave function collapse in particular) involved.

I personally think he's probably wrong, but who really knows?
Or even simpler: if cells are just machines, then there is no reason why a computer couldn't perform the same operations. I'm not a philosopher, but I believe this comes down to materialism vs a belief in the supernatural.

Having read about Penrose's positions before, this is indeed what is he proposing in a roundabout way: that there is an origin to "consciousness" that is for all intents and purposes metaphysical. In the past he pushed the belief that micro-tubules in the brain (which are a structural component of cells) act like antennas that receive cosmic consciousness from the surrounding field.

In my opinion this is also Penrose's greatest sin: using his status as a scientist to promote spiritual opinions that are indistinguishable from quantum woo disguised as scientific fact.
