left-struck··on Mojo-V: Secret Computation for RISC-V
It’s called Mojo-V not just Mojo
left-struck··on You will own nothing and be (un)happy
I’m slowly going more and more down this route but I’m curious about what you or others are using for banking apps and parking payment apps. I actually want to switch to graphene OS but there are always these rare corner cases.

Today alone I payed something like 20% extra because I didn’t want to download an app to pay for parking (other parking places won’t even accept payment without the app) and I had to download a closed source app to activate a sim card.

left-struck··on The 'Toy Story' You Remember
“So, we have five or six extremely high-resolution monitors that have better color and picture quality.“ I would love to know what qualifies as extremely high resolution for computer monitors circa 1995
left-struck··on ChatGPT terms disallow its use in providing legal and medical advice to others
Your comment actually hints at this towards the end but yeah this doesn’t just apply to medical and legal topics.
left-struck··on Free software scares normal people
I think GUI tools lend themselves more to being able to discover functionality intuitively without needing to look anything up or read a manual, and especially so if you’re coming back to a task you haven’t done in a while. With CLI I constantly have to google or ask an LLM about commands I’ve done many times, whereas with a gui if I do it once I can more easily find my way the next time. Anyway both have their place
left-struck··on The underground cathedral protecting Tokyo from floods (2018)
> In addition to this underground chamber, there are two massive pumps on either sides, which divert the water from whichever river is surging to the other (Arakawa & Edogawa possibly).

You probably mean pumping stations right? Usually single pumps don’t have that kind of flow rate. Just a nit pick though, your comment was really interesting!

left-struck··on Are noise-cancelling headphones impairing our hearing?
I suspect the absolute pressure required to crush a hair would be measured in MPa, orders of magnitude more than the pressure difference from a sound level that would kill you. The damage probably comes from the vibration ripping apart nerves cells at the base of the hair, but again that’s speculation on my part. So no vibration, no damage.
left-struck··on Are noise-cancelling headphones impairing our hearing?
I’m pretty ignorant on human hearing and hearing damage but my understanding is that hearing damage from loud noise is caused when a loud sound mechanically vibrates little hairs in your inner ear and the product of the magnitude and duration of that vibration is high enough to cause damage.

Noise cancellation stops or reduces the magnitude of that vibration. So I have to disagree, I don’t think noise cancellation would cause more damage in the way you’re describing.

I didn’t read the whole article but from what I read it sounds like it’s a brain issue not a physiological one.

left-struck··on The number line freaks me out (2016)
I think it’s slightly more fun to say there are an infinite number of numbers between each number on the INFINITE number line
left-struck··on Plane crashes, overturns during landing at Toronto airport
It wouldn’t surprise me at all if aircraft can generally slow down faster than trains, assuming level flight and grade (or the same climb rate)

It’s not really fair though, because the aircraft has so much force acting against it from how fast it’s moving. If somehow a jet was moving at train speeds and could only use its aerodynamic surfaces to slow down, it would probably take a while.

left-struck··on Take the Pedals Off the Bike
Release the clutches linearly in half a second with the engine at 1k rpm and bunny hop away lol

But you’re totally right. You can pull away quickly by letting your rpm build up and choosing an aggressive clutch position while applying enough throttle to keep the rpm constant, alternatively in most cars you can pull away on a fairly steep hill with no throttle if you just barely let the clutch engage and hold it at that point until the car is moving steadily

left-struck··on Take the pedals off the bike
Oh man yeah the advice about continuous motion is not right. A clutch is a torque control device, in the case of a car it’s more like a torque limiting device. The more you let the pedal out the more torque you allow the engine to apply to the wheels up until the point where the torque you allow exceeds the engine’s available torque at a given rpm and throttle position. So if you’re constantly letting the clutch out you’re ramping up the torque limit linearly but the engine speed and wheel speed don’t match and if the engine speed is low of course the engine can easily stall.

Instead what you want to do, what most people do subconsciously is let the clutch out partially until it is allowing the engine to apply some of its available torque but not all, and then pause there until the car’s speed roughly matches the engine speed, at which point the clutch will stop slipping even though you still have the pedal partially depressed, after which you should be able to rapidly raise your foot from the clutch and feel no acceleration or deceleration. For an experienced driver that pause is less than like half a second from standstill. Also technically the point at which you want to pause the clutch let out depends on a whole bunch of things like how quickly you want to pull off, how much torque the engine can provide and whether you’re on a hill etc, but we just do this intuitively with experience.

This is like a super over-complicated way to think about it and I would never try to teach a learner driver by first explaining this lol but the point is, you find the engagement point and hold there for a while and then release when the car is moving. This is what we all do but it helps to understand why we do it so we don’t explain things wrong.

I feel like people also don’t get what applying more throttle does while the clutch is slipping. All it does is raise the engine rpm, it will apply absolutely no more torque (and therefore acceleration) no matter how much you press down the throttle. While the clutch is slipping the clutch pedal controls your torque and therefore acceleration. You need some throttle though to give you some room for error and some minimum torque to work with.

left-struck··on Mysterious New Jersey drone sightings prompt call for 'state of emergency'
I agree that sensors could mean anything, and so could “intelligence data” but just because the positive was not confirmed “It’s a spy balloon” doesn’t mean that the negative was confirmed “It’s not a spy balloon”. Personally I am unconvinced either way and actually don’t care whether or not it was a spy balloon, my point is that the bbc article absolutely does not say that the pentagon thinks it wasn’t a spy balloon.

Also keep in mind the US military isn’t necessarily going to be honest about what they think the balloon is and how much they can discern about its purpose.

left-struck··on Mysterious New Jersey drone sightings prompt call for 'state of emergency'
While your concern is still totally valid, if a civilian mistakes a 747 for a drone and shoots at it with anything but a laser, they’re gonna miss lol. It will probably be out of range in fact.

In other words, if you’re within 1km (0.6 miles) of a large passenger jet, you’re absolutely not mistaking it for a drone.

Oh yeah I totally get having a niche hobby. I’ve personally considered starting a collection of photos of modified 90s Japanese cars. I take photos all the time of my cat with a “pro” camera but that doesn’t make me a professional cat photographer. Now if I were making money from it on the other hand…

I would be amazed if there’s enough of a demand for drone photos to support someone

left-struck··on Mysterious New Jersey drone sightings prompt call for 'state of emergency'
Maybe the article had a different headline and they didn’t read the actual article? I’m baffled how some could read that incredibly short article and come away with any assertion about what the pentagon thinks about the balloon other than that it can collect ”intelligence data”
left-struck··on Mysterious New Jersey drone sightings prompt call for 'state of emergency'
From the article you just linked

‘Pentagon spokesperson Brigadier General Pat Ryder said on Thursday that the US was "aware that [the balloon] had intelligence collection capabilities". But "it has been our assessment now that it did not collect while it was transiting the United States or over flying the United States".’

When did the pentagon confirm it was not a spy balloon? The article is very short and the meaning is clear, it doesn’t say anything about whether the pentagon thinks it’s a spy balloon.

Please tell me that’s someone who takes photos using drones not photos of drones - for a living

left-struck··on Fire risk assessment of battery home storage compared to general house fires
I don’t know anything about sodium based batteries but sodium itself is a serious fire danger. Sodium is explosive in water, more so than lithium I believe.
left-struck··on Contradictions in photography advice
Yeah that’s a good point about the real-time decisions. I’ve been thinking about it since my comment and I think I’ll give raw another shot. It has such a wider dynamic range* than jpg and maybe it’s a way to almost future proof your photos.

*jpg photos in sRGB Also bit depth difference is huge

left-struck··on How much do I need to change my face to avoid facial recognition?
Another related thing to consider, if she had plastic surgery what are the odds that among a billion people there isn’t someone whose face looks more like her original face than her face looks like her original face.
left-struck··on Contradictions in photography advice
In street photography, and any photography really, paying attention to light is super important. I’d argue it’s more important when you can’t control it.

Sure you could just go out onto the street, take a bunch of photos and pay no attention to light, but if you want to improve your photos, or know why good photos are good, paying attention to light is just as important as say composition

left-struck··on Contradictions in photography advice
Alright here’s my counter point. The useful range (min focal length to max focal length) of most zooms is small enough that if you have a high end sensor and you’re not doing large prints you might as well use a prime. It’s like you don’t need those intermediate steps.

With zooms, if you need wide angle you have to switch to a wide angle zoom, if you need telephoto you need to switch to that. There are some exceptions like zooms that cover ~35-140 but most of them fall into one of the categories that a prime falls into

left-struck··on Contradictions in photography advice
I used to think like you but lately I just can’t be bothered with editing too much and with the raw workflow so I mostly shoot in JPG these days. I shoot in raw when I’m shooting in situations where the lighting is difficult.
left-struck··on The correct amount of ads is zero
To be fair advertising without collecting sensitive data does exist. I think the collection of sensitive data is a more serious issue so let’s not say all ads are abusive in that way.

However, I agree with the position that all ads with some small exceptions are a negative thing. I think the incentives behind advertising are inherently perverse because of what they are at their core, an attempt to manipulate (if they work then a successful attempt!). They are dishonest and inauthentic by design. It’s possible to create an ad that is like “hey this thing exists and this is strictly what it does without any exaggeration” but that basically never happens because the people who make ads have no external incentive to do that.

I think a much more ideal situation is where a user searches for something on a search engine, or an LLM or whatever, and they are shown as unbiased as possible results. This way the people making good products get their exposure and the people looking stuff get the stuff they want. Of course there’s a lot of problems in practice with that as well.

I don’t claim to have a solution, and I don’t think making an add is like super immoral, but I think ads are a scourge on our society and culture.

I know you’re joking but to be clear, if they have symptoms they wouldn’t need a shot, it’s too late.
left-struck··on In the Rockets' Red Glare: The past and future of hot-rodding in America
I can’t speak for other markets but in Australia millennials are really into Japanese cars, 4X4 or our domestic cars. And the zoomers seem to be into 4x4 as well.

I would argue modified cars are more common than ever in Australia, it’s just not what you’d expect when someone says modified cars, it’s 90% large SUVs and other 4x4 vehicles.
