jeremyvisser··on Apple's weird anti-nausea dots cured my car sickness
The difference is very simple:

Apple uses the derivative (i.e. rate of change) of acceleration, while all the other (ineffective, in my experience) third-party apps simply use acceleration.

People with motion sickness can deal with speed just fine. While relaxing on an equatorial beach, you’ll have no qualms hurtling around the poles at 1600 km/h.

Acceleration is also perfectly fine for motion sickness. Most people are being pulled towards the centre of the earth at 1.0 G with no complaints whatsoever.

But the significance during motion sickness is the rate of change of the rate of change. That thing where the vehicle slows down, turns a corner, goes over a bump.

This is why Apple’s motion cues actually work, because they use what actually matters for motion sickness.

jeremyvisser··on Unpowered SSDs slowly lose data
Here’s the thing. That SSD controller is the interface between you and those blocks.

If it decides, by some arbitrary measurement, as defined by some logic within its black box firmware, that it should stop returning all blocks, then it will do so, and you have almost no recourse.

This is a very common failure mode of SSDs. As a consequence of some failed blocks (likely exceeding a number of failed blocks, or perhaps the controller’s own storage failed), drives will commonly brick themselves.

Perhaps you haven’t seen it happen, or your SSD doesn’t do this, or perhaps certain models or firmwares don’t, but some certainly do, both from my own experience, and countless accounts I’ve read elsewhere, so this is more common than you might realise.

jeremyvisser··on How bloom filters made SQLite 10x faster
> Even if you are running it all on the same machine, a separate worker queue process and a web server process cannot share an SQLite database file.

Excuse me? The only way you would be able to come to this conclusion is if you did no reading whatsoever and never tried it.

This “confidently wrong” attitude really needs to stop.

jeremyvisser··on You don’t want to be on Cloudflare’s naughty list
Not an answer to your question, but an indicator of shared culture: Tesla vehicles also don’t support IPv6 whatsoever.

Things you might use an internet connection for in your Tesla include triggering air con remotely, live traffic and satellite maps, streaming music or online radio, web browsing, or YouTube/Netflix/Disney+ clients.

It completely refuses to use IPv6 over mobile or wi-fi. Also it refuses to access anything over IPv4 (apart from DNS) which resolves to an RFC1918 address, even if it's connected to said RFC1918 network.

So yes, Starlink and Tesla are different companies, but I see cultural parallels which I'm sure surprises nobody.

jeremyvisser··on No Dislikes has officially ruined YouTube for me
This is another clearly automated channel I found recently.

For some reason I was searching for some game music I remembered from childhood (OMF 2097), and came across this video: https://www.youtube.com/watch?v=cV1F_IwdceU

It was strange, because it was titled like “how to play this music”, except clearly it was just a MIDI file piped through a visualisation into the video; as a musician I know it’s useless for the task at hand.

Looking at the other videos on the channel, I found dozens and dozens of the exact same video intro, except with a new MIDI file: https://www.youtube.com/channel/UCCiu4h1KfC9ODVz90JRogdg/vid...

Presumably the author has automated this by scraping tons of free MIDI files, rendering them to video, prepending a generic video intro, and hoping to cash in.

jeremyvisser··on Australia’s new mass surveillance mandate
> The app allows people who are required to isolate to opt to do their isolation at home, rather than stay at a quarantine facility.

> Nobody is being forced to use the app.

If there’s a cost difference, I’d say that “forced” is an unfairly neutral word to use.

SA is charging upwards of $3000 (for 1 adult, plus $1000 each additional adult, plus $500 per child) for hotel quarantine [1], and though I can’t find a definitive source, your link does say it is intended to be a “cost effective alternative to medi-hotel quarantine”.

So for a family of 2 adults, 2 kids, being charged $5000 to avoid using the app isn’t real freedom. If it means the difference between putting food on the table or not, it’s no choice at all.

jeremyvisser··on Google is saving $1B per year as a result of employees working from home
Not the O.P., but speaking from experience, yes, a thousand times yes.

Here in Sydney, Australia, both office and WFH are available at my work. I'll have anywhere between 0% and 90% of my team in the office depending on the day or week.

In my experience, even being the only one in the office is a thousand times better than WFH.

Whether teammates are WFH affects me less than whether I'm WFH.

Considering you're commenting in an international forum, what is "this country"?
jeremyvisser··on DisplayPort and 4K
DisplayPort does audio.

jeremyvisser··on I miss Inbox, so I hacked Gmail with a little CSS magic (2019)
> There's no "Send after X duration" or "Send at X time", so you can't write something at 3am and schedule it to be sent during work hours.

Actually, this exact feature exists:

jeremyvisser··on Encoding your WiFi access point password into a QR code
Can confirm.

I was visiting a nature reserve where the trail opened to a resting area with some seats. A tree had a woodcut QR code on it, so I thought I'd scan it to find out more about the area.

Turns out, the QR code linked to some tracking site with a short URL. Even worse, the short URL had since been deleted, so I have no way to know the original URL it went to.

TAFE anecdote time!

In my TAFE class, I was asked to list two examples of operating systems.

I listed Linux and eComStation. The teacher had never heard of eComStation and marked me wrong.

Refused to correct my mark even when I proved him right. I'm still bitter about it a decade later.

jeremyvisser··on Why I don't love Light Rail Transit
> This is very clear in the article: poor transportation from where they can afford to live to the expensive area around the station.

This is precisely why I'm saying the article doesn't make sense: how about exploring the idea of building the LRT in the non-gentrified areas, i.e. where you would supposedly put your bus routes.

jeremyvisser··on Why I don't love Light Rail Transit
This is a lengthy article, yet the author fails to address any of the concerns he claims to be countering.

He claims only the rich use light rail. But what is it about a light rail that causes a poor person to look at it and walk away deciding it's not for them? It simply doesn't make sense. Build LRT to a poor area, people will use it.

He then shows an infographic of a hypothetical city covered in bus routes, alongside the same city covered by one LRT route through a gentrified area. This is unfair. How about comparing equivalent LRT routes with bus routes?

Money sunk into buses is money no longer spendable on LRT.

There's an infographic that shows bus route ridership compared to LRT route ridership but we learn only the what, not the why.

Also, the article makes no mention whatsoever of Melbourne, an example of LRT working very well for over a century.

I'm disappointed to say that I learned exactly nothing reading the article.

jeremyvisser··on Anxiety nightmare comes true for pianist at competition
While can't comment on whether it is as repetitive, I would point out that the commonality between baroque and pop music are their simplicity and emphasis on chord changes at their core.
