Darthy··on This open problem taught me what topology is [video]
I've got a problem with that video that starts at 4:15. He seems to jump to the conclusion that for every midpoint there is only 1 distance. But that midpoint is formed by picking 2 points on the edge, and one could easily pick two other points on the edge that have the same midpoint (but have a different distance). He did not address that point at that point in the video, and for the next 2 minutes I kept raising that point in my mind. After he continued down that path not addressing that point, I felt that I must have missed something, or that more intelligent math viewers would have solved that open question in the mind in seconds and I am not mathematically inclined enough to be the target audience. And I stopped watching that video.

I think good educational videos are the result of a process where a trial audience raises such points and the video gets constantly refined, so that the end video is even good for people who question every point.

Darthy··on My favourite colour is Chuck Norris red
The parsing outline in the article omits that there are also 140 hard coded color names in html: https://htmlcolorcodes.com/color-names/
Darthy··on $8k Suzuki from India received a 5-star crash test rating
Be aware that for global NCAP, safety ratings are dependent on the vehicle class. If a subcompact car receives 5 stars, this does not mean it has the same probability of survivability in full frontal crash as a large executive luxury sedan that received 5 stars.

In fact, if there was a head-on crash between this car and Mercedes E-Class, and you're planning to be in one of the cars, I would advise you to chose the Mercedes.

Darthy··on Stabilizing the Obra Dinn 1-bit dithering process (2017)
I recently downloaded it from GOG and tried to play it on a 5K studio display. I wasn't able to get a result that did not blur those beautiful pixels, which is such a shame. Yes, I did go into all those setting menus.
Darthy··on I designed a Dieter Rams-inspired iPhone dock
It looks beautiful, thanks for the write-up!

Question: Most docks have ample space around the phone to grip it and remove it from the dock easily. Your design encases the phone on every side. How do you get the phone out in the morning?

Darthy··on Cybercriminals are stealing Face ID scans to break into mobile banking accounts
I think the interesting part is that either this software was able to access the biometric scan feature and inject their own data into it (which third party software should not be able to access or inject at all, only the OS should be able to access, and injecting should be impossible), or was able to access the Secure Enclave directly (which would be a really big deal and a major breach).
Darthy··on Early Apple Vision Pro Adopters Alarmed to Learn VR Porn Doesn't Work
According to the article, the Vision Pro will not play common side by side videos. It has its own standard ("WebXR clips"), but nobody distributes these, and videos from that standard are also not playing correctly on the device.

Most likely there won't be any app that plays porn videos because Apple will not allow them. From the article:

> Steve Jobs notoriously believed that the company had a “moral responsibility” to block porn and suggested that “folks who want porn can buy an Android.”

And general movie playing apps might also be required to implement a porn filter. Remember Apple insisted that all Reddit and Tumblr apps have such a filter, otherwise they wouldn't be allowed in the Apps Store, the only way to distribute apps.

If you believe tech battles are decided whether there is access to porn (VHS vs Beta comes to mind), the Apple Vision Pro currently doesn't look like a winner.

Darthy··on Apple Music will now pay 10% higher royalties to artists for Spatial Audio music
Peter Gabriel's 2023 album "i/o" has some quite inspired Atmos mixing going on. The track "The Court" is particularly nice. Make sure you pick the "In-Side Mix" version of the album.

Nice Atmos tracks by other artists imho:

- Jaguar by Victoria Monét

- get well soon by Ariana Grande

- Heroes (feat. Mindy Jones) by Moby, Album "Reprise"

Darthy··on US developers can offer non-app store purchasing, Apple still collect commission
Apple Vision Pro is coming out soon, with the same terrible rules for app developers.

We should put out an open letter to Apple that we will collectively ignore that product until it contains more favourable terms.

Darthy··on Rabbit: LLM-First Mobile Phone
In the linked keynote, Jesse Lyu mentions that LLM won't help us actually do tasks - there are currently no so-called "agents" that do something simple like book a flight - the best way to do it is still to click the buttons yourself.

Rabbit means to solve that by creating a "LAM", a "Large Action model", which is a service by Rabbit that will click interfaces for you. I'm not sure this is the right approach - if it is successful, it will lead to more centralisation around Rabbit.

I agree this is a problem, but I feel a better approach would be to have a market of agents that for a small fee actually handle the whole transaction for you. So there might be multiple parties that say they can buy Delta Flight DL101 tomorrow 21:10 for various prices - some might be a service like the Rabbit LAM, others might be booking platforms, and there might even be airlines themselves. And now an agent-concierge that you choose once at the start will look at all the parties, and then pick and buy the right flight for you. This will make the problem a problem of an open market, where good speedy service is promoted, and prices get ever lower. And if the Rabbit LAM gets outcompeted by an ever better speedier solution, that would be a good thing. (This will also allow us to move away from our current dreaded attention-based economy where e.g. a booking websites tries to exploit your required presence during waiting times, which the LAMs would also solve, but, like I said, let's not move towards more centralisation.)

Darthy··on Organ pipe physics
I don't think [4] is a marketplace in the sense that the expansions are from third party creators. They are all created by Modartt themselves, one by one over the past 15 years. After all, you can't just sample another instrument, there is a lot more work involved.

That might also be the answer why this doesn't yet exists for Organteq. It just takes time.

But your reason why you need good selection of expansions might be valuable market insight for Modartt. I know they appreciate feedback, I've talked to them before, so I'd suggest you tell them your concerns.

Darthy··on No-Bullshit Games
It's a good list, but I feel "Mario Run", a single player game that refuses to run if not connected to the internet (and will also fail to run in a few years when Nintendo gets bored and turns its servers of) is a prime example of a game that does indeed contain bullshit, and should not be included in this list.
Darthy··on Sony announces a9 III: first full-frame global shutter camera
I've got the smallest digital full frame (the Sony RX1). Compared with your linked analog Ricoh GR1v, the Sony is bigger because of its much more capable lens. Putting the Ricoh lens on the Sony would have limited the quality a lot. It's a question of "do the elements fit together?".
Darthy··on Is the end of AIDS in sight?
That's revolting. Which radio show was this?
Darthy··on Techdirt has been deleted from Bing and DuckDuckGo [fixed]
Gabriel, could you please clarify once and for all: for "traditional web links", how much do you rely on bing? The user consensus seems to be 100%. What is the official number from you? Thanks!
Darthy··on Mullvad VPN was subject to a search warrant – customer data not compromised
I assume you mean "If any opponent suspects your IP address..."

You can counter that easily. That's why you should use a multihop VPN.

Darthy··on ChatGPT has trouble giving an answer before explaining its reasoning
Here's a thought: If you let ChatGPT be idle, thinking to itself, dreaming and planning, this might actually cross the boundary towards sentience - of what we would call somebody who is alive. So there might be some safety and moral concerns.
Darthy··on Podman vs. Docker: Comparing the two containerization tools
I'm using Colima ( https://github.com/abiosoft/colima ) and am very happy with it so far.

Here's an article about it: How Colima is a good alternative to Docker Desktop ( https://kumojin.com/en/colima-alternative-docker-desktop/ )

I'm using Colima together with DDEV ( https://ddev.com ) to create and run PHP projects (webserver + db) in containers. Clean, very easy to use, and fast.

Darthy··on The erosion of the Mac experience
Maybe you're refering to subpixel rendering, which Windows still has, but has ben phased out on Mac with the introduction of retina displays? https://en.wikipedia.org/wiki/Subpixel_rendering#OS_X
Darthy··on Ask HN: What MIDI micro/nano keyboard(s) do you like? (Electronic music)
Love my Seaboard Block. Fits the size. Doesn't look to shabby next to Apple stuff. It's not your typical sample-trigger keyboard, but pair it with an mpe-Synth like Equator2, learn to play it expressively, and you get some amazing results.

Darthy··on Moiré No More
Since the halftone dots are in a matrix that is at an angle, can't you just write a small program that measures the size of each halftone dot and stores that measurement? Then map the measured size to a grey value (supersmall = near white, big = black), and you have recovered all the information in that image.

Then just counter the rotation of the matrix to get the best possible right-side-up scan.

Darthy··on Surround Sound in Headphones
That sounds interesting! Whats the url on your website where I upload my right ear image, enter my cc details for a one time payment and get to download my HRTF in the standard AES69 format?

Darthy··on First commercial curved CMOS sensor from startup CURVE
That’s not the first - Sony already released a product with a curved sensor in 2014, the KW1: https://www.sonyalpharumors.com/sony-confirms-kw1-perfume-se...
Darthy··on “I monitor my staff with software that takes screenshots”
You’ve got to be kidding.
Darthy··on Kazuo Ishiguro (1989)
Very interesting. Is the impact similar in the film?
Darthy··on Prosopagnosia: The artist in search of her face
Wouldn’t a custom subtitle track just for people with Prosopagnosia help? Like every time a character appears, show her/his name for 5 seconds. If there isn’t already a subculture that creates fan-made subtitle tracks, we should create one.
Darthy··on Apple says game streaming services violate App Store policies
So Apple claims that Netflix is okay but that new Microsoft service is not, because the former one is a video streaming platform while the latter is a interactive game streaming platform.

Now Apple, please explain me this: Netflix is also a interactive game streaming platform. They have Bandersnatch, Interactive Carmen Sandiego, Interactive Puss in Boots, the Interactive Bear Grylls You vs Wild, and freaking Minecraft Story Mode which for all intents and purposes is a fully real game.

Netflix is a game streaming service, and it's on the app store!

Apple is massively inconsistent here, and has some major explaining to do!

Darthy··on The importance of decentralisation
I don't think centralization automatically becomes the status quo.

The reason why we have the current centralization of amazon, facebook, github etc is because the web as we are currently using it has centralization built in: A browser always connect to a fixed server. But that is not god-given, we created it that way 25 years ago, and we could allow additional other ways. A browser could instead also be connecting to a generalized service for selling, communicating etc.

Another way how this could be changed: We could bypass centralization by ensuring that a webpage on ones device can aggregate many services, by emulating visiting other websites in the background, and we make sure that those sites will not be able to find out that are are not being called directly as the main address, but will only be giving out their data. For that, we would have to remove current Cross-domain requests restrictions.
