The analogy I always use is the filling a water bottle one. In the beginning when the bottle is empty you can go full power and fill it up with high pressure. At the end you need to reduce the pressure to not spill the water. I know it doesn’t work like this with batterie cells but close enough. I had the same aha moment when realizing this. It’s one of the things no one normally thinks about in a world where everything is a given.

>anyone who has their I-140

That’s doing a lot of heavy lifting, which is what I meant by depending on where they are in the process.

You have 2 employees at the same company in a bad job market.

If employee A gets laid off or fired, he has enough savings for a 2 year job search and can pay for COBRA for 18 months.

If employee B gets fired or laid off, he has 60 days to find a job and make it through the hiring process.

There’s been 1 round of layoffs and there are rumors there might be another. The boss asks both of them to put in extra hours, which one is more likely to say no?

Yep, I have a Shun with micro serrations ([0]) that will slice a tomato so finely you basically feel no resistance.

The only downside is that you can’t really hone or sharpen it yourself so you have to baby it. I’ve had mine about 15 years and have sent it in one time for their free sharpening at about the 11 year mark. At least Shun blades hold their edge a really long time.

> The work would simply disappear without them.

I think you underestimate the capabilities of the American worker, after all, they have created the circumstances in which your company surrounds itself and succeeds.

If your job cannot exist without an endless stream of underpaid, overworked Third word country immigrants then you don't have a job, you have a mill.

That's cynicism.

Everything has pros and cons. You haven't said a single pro. You haven't added any real cons to what I said, and made up hypothetical ones.

It's a sales pitch so you're saying why you wouldn't buy it. I'm not ordering one either, 500 is a bit steep for me. If he just showed off the technology, I suspect people here would be more enthusiastic about it, even if you wouldn't bother to buy it yourself.

I'm not saying you're wrong (at the price point), but that the framing of whether we're going to buy it is a result of the marketing.

> Theres the little matter of the US imposed Plaza Accords that have been skipped in the timeline there , which are widely acknowledged to have precipitated Japan's lost decades.

Actually, no. The CPC generally argues this is the case, but it is largely incorrect. Japan responded to the Plaza accords by attempting to massively increase stimulus and preserve the structure (significant industrial, limited service/consumption economy) they started.

In contrast, (West) Germany kept the stimulus relatively low and rotated into higher productivity enterprises and R&D and had a substantially lessened impact. See this (https://www.atlantis-press.com/article/125961733.pdf)

The whole "US destroyed Japan with the Plaza accords" is basically CPC propaganda.

China will have its own issues, but I would guess they look more like the 1992 sterling crisis where China cannot hold its yuan peg as it continues to have trade expansion without corresponding foreign exchange growth.

> Integrating Rust shows you have too much time on your hands; the people who are affected by that, not necessarily so.

As cited elsewhere in the this thread, the person making this proposal on the mailing list has been involved in significant contributions to git in the past, so I'd be inclined to trust their judgment about whether it's a worthwhile use of their time in the absence of evidence to the contrary. If you have something that would indicate this proposal was made in bad faith, I'd certainly be interested to see it, but otherwise, I don't see how you can make this claim other than as your own subjective opinion. That's fine, but I can't say I'm shocked that the people actually making the decisions on how to maintain git don't find it convincing.

AVS was created by the USB PD specification team (the USB Promoter Group/USB-IF), not Apple. AVS was introduced as part of PD 3.1 in 2021, albeit for >100W only. I believe Google was technically first out of the gate with a charger that supports the PDS 3.2 flavor of AVS.

A rackmount case from Rosewill costs a couple of hundred bucks or so, new. And they'll remain useful for as long as things like ATX boards and 3.5" hard drives are useful.

I mean: An ATX case can be paid for once, and then be used for decades. (I'm writing this using a modern desktop computer with an ATX case that I bought in 2008.)

PCI Express lanes can be multiplied. There should frankly be more of this going on than there is, but it's still a thing that can be done.

Consumer boards built on the AMD X670E chipset, for instance, have some switching magic built in. There's enough direct CPU-connected lanes for an x16 GPU and a couple of x4 NVMe drives, and the NIC(s) and/or HBA(s) can go downstream of the chipset.

(Yeah, sure: It's limited to an aggregate 64 Gbps at the tail end, but that's not a problem for the things I do at home where my sights are set on 10Gbps networking and an HBA with a bunch of spinny disks. Your needs may differ.)

Rust will, in fact, make it significantly easier to contribute.

In C, you have to remember lots of rules of when what is safe and what locks to hold when. In Rust, APIs are structured to make unsafe use impossible without explicitly saying `unsafe`.

Concrete example: in Rust, locking a mutex returns a handle that lets you access the data protected by the mutex, and the mutex is unlocked when the handle is dropped.

I scavenged an LCD screen from an old laptop and put it in a cheap case from AliExpress. It has a small driver board and a steel case. I use it as a small/portable TV. But it has USB-C for input and power, and HDMI input. It’s just about the size of an iPad and very nice.

I think that would work very well in a headless/data center scenario.

Let's use game theory for #3.

- You're an American running a business in the US (or somewhere else).

- Trump (or some TLA) demands that you do something, holding a threat over you.

What do you do? Are all Americans actually pawns of MAGA, or the spook agencies? How should the world respond to this implication?

I suspect that many of the accidents that happen with touchscreens are frontal collisions with slowed down cars when the driver is distracted with the touchscreen. A few regulations that might help with this:

All cars with touchscreens need to have automatic forward collision detection and emergency braking, and if it's not enabled, the touch screen should have very limited functionality. No scrolling music, no sending texts, etc.

A car with forward collision detection should show a clear warning a few seconds before it triggers the brakes, and indicate the warning on the screen. Chevy is already doing this by showing a "seconds before collision" indicator on the display in front of the driver. They should make it even louder (visually) and disable the touchscreen if it falls below 2 seconds.

A few years back I fumbled my iPhone so badly that when I tried to catch it I knocked it further up in the air. It flew up dropped all the way down to the concrete subway platform I was on, landing face down. It was loud and worrisome, but the phone was perfectly fine outside of some scratches on the lip of aluminum around the screen.

So it seems like the screens are not easily broken anymore. Though that event did lead to me using a case on my next phone just to avoid chancing cosmetic damage on it.

I guess in a certain sense, yes, the total number of lines of code in C will go down, so the difficulty of finding a place to contribute will go down by that metric. On the other hand, I'd argue that it seems rather unlikely that literally all of the C code will be gone from git at least over the next couple of decades (and that's assuming that there's even a desire to rewrite it entirely, which doesn't seem like it's anywhere close to even being possible to discuss seriously any time soon), so it seems like the amount of difficulty will be so small that it's a bit silly to worry about it. Keep in mind that there's still not anything stopping new code from being written in C just because new code might also be possible to write in Rust. Right now, it's literally impossible to contribute Rust code to git, so if it becomes infinitesimally harder to contribute C code to make contributing Rust code possible, that's still a arguably a much larger increase in the net "contributability" of the git codebase, for lack of a better term.
Show HN: Uniqalc – No-code calculators for SaaS and AI pricing
by phil611 | 2025-09-21 00:29:32+00:00
Hi HN, I built Uniqalc because I was frustrated with how confusing pricing pages can be.

With Uniqalc, you can: Build and customize a calculator without writing code. Turn your pricing page into an interactive, “shopping cart–style” experience. Embed it directly on your site so customers can self-serve estimates. I’d love feedback on whether this solves a real pain for you (or your customers), and what would make it more useful. Thanks!

Also, if many western countries don’t get their shit together, their lives will be greatly influenced by China at current trajectory. Which particularly involves the negatives. China's success should be motivation to many western ex-empires, excellence nostalgia hubs and industrial graveyards.

And yeah, credit where credit is due, I think no observer seriously doubts the great feat China pulled off in such a short period of time, even if the stats are not reliable. People travel there, Jobs warned about this years ago.

And between US, Russia and Israel, China is the least obnoxious villain in my news feed. They somehow conquer the world without cringe overdrive and the undignified post-pretending social media executive memefare. China does not make me wanna drive a dining fork into my frontal lobe, it’s more like the cough that doesn’t go away.

There are times when an exhaustive and formal definition of a word is not required. This is one of them.

However, I am aware that for some people, it can be annoying when someone else (me in this case) is seemingly lazy or just plain wrong when deploying words.

I used to be somewhat unkind about grammatical errors but let's face it: grammar is what the majority of people say it is and not what is pinned down in a book half-read and quarter-remembered from years ago.

A bit is perhaps the smallest addressable unit of storage (says my light switch) A byte manages to convey 256 different states and I would need eight light switches to store them.

>I thought there was a robust android emulator for linux such that I could run android apps - and call an Uber or whatever - from desktop linux ...

There are some but not really great and it will become impossible very soon with remote attestation and play integrity. Already Uber is one of the few apps that have the hardware attestation keys for grapheneos manually added.

You can always edit the service directly. There's nothing stopping you from doing that, and most people probably do it this way. Doing that would make it just like any other application with a config file.

BUT have you ever had configs overwritten by an update? Have you ever found an update to break your config? These are really quite annoying problems to deal with. Having the override file basically means you can keep the maintainer's config as your "gold standard" and then edit it without worrying of fucking things up.

This is the difference to me:

systemctl edit: It is clearly defined what you changed. Your changes will not be overwritten by an update. directly editing config: File may change with update. You won't be notified of said change. If you didn't write down what you're changes were, you need to redo that work and figure it out all over again.

The pros outweigh the cons IMO. I had to get myself into the habit of doing `systemctl edit foo` instead of `sudo vim /etc/systemd/system/foo.service`, but that's provided more benefits than the annoyance of building this habit.

I've invested close to a thousand dollars in sharpening tools over the years. I keep my knives super sharp as a hobby more than anything. I'd still love to have one of these in the drawer for certain tasks. It's ugly and clunky but I'd probably still use it on a semi-regular basis for warm breads, cheeses, etc. I bet the action would help with sharpening as well.

I do wonder if a tuning fork or 'mass on a stick' hidden in the tang could provide enough vibration to help with the sticking. You'd probably have to smack it with every cut but it's so rarely a problem that would be fine.
by 65 | 2025-09-21 00:32:14+00:00
I find it funny most of these comments are about how unnecessary this thing is.

To me it has immediate appeal to make cutting easier. It's also really not that expensive. I suppose this is the same site that is crazy about AI and thought Dropbox would flop. This thing has more utility than AI to me. I suppose being a software person can warp your perception of the real world.

The concept of the knife is interesting. I could see myself buying one if I had that much money lying around.

Maybe if the home chef who needs a leg up sees this it would prevent them from spending that much or more on more expensive knives and maintenance products. For those of us who know our way around the kitchen I’m not sure how much benefit I would get out of it.

Also did anyone think some of the cutting segments, particularly the radish, seemed sped up? The movement of the blade and hand looked a bit unnatural.

I personally watched Scott spend years working on the project and obsessively iterating on the steel, the vibration pattern, the circuitry, the handle, and the form factor. Scott is a hacker, one of us for sure. I mean, the guy built a custom robot just to measure cutting efficiency...

The knife is amazing and exactly as shown in the video. Rand Fishkin has a nice short on LinkedIn trying out the knife too. I think he shows one his (sharp) kitchen knives slicing through a lemon, then the Ultrasonic. It's astounding.

Sounds simple:

> In an undercover operation last year, the FBI recorded Tom Homan, now the White House border czar, accepting $50,000 in cash after indicating he could help the agents — who were posing as business executives — win government contracts in a second Trump administration, according to multiple people familiar with the probe and internal documents reviewed by MSNBC.

> The FBI and the Justice Department planned to wait to see whether Homan would deliver on his alleged promise once he became the nation’s top immigration official. But the case indefinitely stalled soon after Donald Trump became president again in January, according to six sources familiar with the matter. In recent weeks, Trump appointees officially closed the investigation, after FBI Director Kash Patel requested a status update on the case, two of the people said.

> It’s unclear what reasons FBI and Justice Department officials gave for shutting down the investigation. But a Trump Justice Department appointee called the case a “deep state” probe in early 2025 and no further investigative steps were taken, the sources say.

...

> On Sept. 20, 2024, with hidden cameras recording the scene at a meeting spot in Texas, Homan accepted $50,000 in bills, according to an internal summary of the case and sources.

Napkin math to get a feel for scale:

12 pizzas. Let’s say large. That’s 12 slices each? Average person eats let’s say 3 slices (some won’t eat, some have one, some have four, some, like me, have brains that are perpetually stuck on Grad School and will embezzle slices until there’s no leftovers). So 144 slices could do maybe 48 (let’s say 50 people). So that’s give or take $4 per person.

That’s one of those “a travel booking error worth of money brings a subjective amount of joy, and the only wrong move would be to stop unless the team wants it to stop” things.

Which is absolutely ripe for some Director of Couch Spelunking to earn their Golden Monocle award for making the spreadsheet show brackets around budgets and win a trip to Boise.

It would be interesting to see if left handers and right handers differ on this. I can adapt to any scheme with basically zero mental effort, and I've heard this is common in lefties (as I am). Stuff like "hold this up to a mirror for answer" never worked for me because I could read a whole page like that without noticing it's backwards. Da Vinci certainly had it with his inverted notebooks

Not sure quoting the guy’s literal words is “smearing”. You’re insisting his literal words mean something other than the plain reading. Again, that’s fine, and your prerogative. As is choosing to avoid virtually anything this guy ever spoke or wrote, while continuing to insist he just, like, had slightly different opinions, man.

He was a hateful, ignorant man. And it’s silly to pretend otherwise.

Even if you're 90% sure it means it doesn't apply to current holders, that's a 10% chance that not cutting your trip short costs $100,000. Very possible your employer doesn't want to pay that and you're suddenly unemployed and visa-less. Unless it's 101% crystal clear the status of visa holders, this was inevitable.

Does that video show him doing actual prep? I 100% believe he made a knife that can make a paper-thin slice of a lemon. But that's not what a chef's knife is for. As someone who thinks the world would be a better place if this product worked and was successful: for god's sake record someone processing an onion. That's what matters.

I’ve seen this in a ton of video players. This is an especially bad example. But it’s so common for the entire top third of the screen to be blurred or darkened just to display a single small UI element in a corner. Stupid design.

The reason it’s especially stupid for Apple is because half of their new design system is about making content front & center.

That is not relevant to the question of how people constantly break something that isn't particularly breakable. If they cared about the cost of the phone, I would expect them to demonstrate slightly less wanton disregard for it such that they routinely smash it. I also know plenty of people that regularly break their phones even with a case.

At some point, you have to conclude people don't actually care if they smash their phone based on how frequently they do it.

As I said, it's baffling.

I'm largely indifferent to errors in spelling, grammar, or definition, save for those cases where others are incorrectly correcting others.

The definition of byte is not a matter of grammar, and here on a forum centered about computing technology and business the distinction that matters not to you matters to many - CHAR_BIT is still part of current standards in important languages and hardware w/out 8-bit bytes is still in current use.

Because motion along the x-axis (left-right) is a body rotation about the gravity vector. y-axis motion is not.

We are upright beings in a gravitational field, so if we see a berry to the left of our visual field, we turn our whole body to face it. Then we walk towards it. We do this from a first person vantage only. We don't see our own backs - just the world itself.

But if a berry is above our visual field, we can't rotate our body that way. That would make us fall over. We instead remain vertical to gravity and rotate a third-person thing. We tilt something else like an arm or stick in the direction. We see this from a third-person vantage only. We see the back of the arm, or back of the stick. If the berry is up high, the part of the stick closer to us is down low. We see the inverted end moving, so it becomes intuitive. Of course, you can focus on the far end of the stick and get a non-inverted intuition too. But this is only possible from a third-person view which we don't often get when our bodies so easily rotate about the gravity vector.

Being faster on a lab-administered test doesn’t tell you anything about your game-playing ability. This research was focused on determining why people invert their controls, nothing more.

> In short, gamers think they are an inverter or a non-inverter because of how they were first exposed to game controls. Someone who played a lot of flight sims in the 1980s may have unconsciously taught themselves to invert and now they consider that their innate preference; alternatively a gamer who grew up in the 2000s, when non-inverted controls became prevalent may think they are naturally a non-inverter. However, cognitive tests suggest otherwise. It’s much more likely that you invert or don’t invert due to how your brain perceives objects in 3D space.
by Brian_K_White | 2025-09-21 00:43:07+00:00
Like with the mouse scroll wheel, there is a reasonable logic to both directions, including whichever direction you don't like.

It's reasonable and natural to have a mental model that the control moves the observer. (move a control up to aim your eyes up)

It's also reasonable and natural to have a mental model that the control moves the object. (move a control down to "grab" the object and move it down)

Both of these are natural and everyone does both in real life totally automatically without thinking.

Everyone looks up and down. Everyone grabs objects and moves them to bring different parts into view.

Probably the preference differences are based on a subconscious/unconscious difference in how you imagine yourself in relation to a document. Whether you imagine yourself as being larger than the document like a person vs a paper, you move the paper, or you imagine the document as larger than you like a fly flying over a paper or like you are virtually IN the document, you move yourself.

> The way it plays out is that the jobs are just offshore to jurisdictions that lack the same labor and environmental protections.

A valid critique of how globalism was implemented in the US. However, this concern could be heavily ameliorated by policy. For example, making US companies using foreign labor adhere to the same labor standards they must adhere to domestically.

Perhaps a reason you’re baffled is because you are thinking only of domestic labor instead of global labor. Most Pro-labor people would, I imagine, consider the global labor pool in their analysis.
