dmitrybrant··on What sonic black holes say about real ones
Neither black holes nor neutron stars extend any kind of magnetic tendrils. There can be jets of matter that are ejected from the vicinity of a black hole (due to the Penrose process or something similar), and those jets can have electric charge, but that's not what your linked study is about.
dmitrybrant··on Technology Behind the Lilium Jet
Off topic, sorry, but: Why do web designers think that they can provide a better scrolling experience than the default system behavior that the user expects in every other interaction?

By the way, hijacking scrolling behavior often breaks other things, such as searching for text in a page. Go ahead, try it, search for a term in that article.

dmitrybrant··on 2021 Tesla Model Y review: Nearly great, critically flawed
I was an early-ish adopter of the Model 3 (2018), and I couldn't be happier with it. I've had zero hardware quality issues, and one software issue where it did a cold reboot one day and forgot my personalization settings. But otherwise it's an absolute pleasure.

However, big caveat: I absolutely do not use Autopilot, nor do I ever plan to. I bought the car because I love to drive it -- the way it handles, the way it accelerates, etc. The only "automatic" feature I've used is literally the cruise control, i.e. maintaining a set speed on the highway. That's the farthest I trust it to do anything automatically.

Being tangentially involved in the field of machine vision / machine learning, I understand the limitations of the current technology, and am appalled at how brazenly Tesla is rolling out this half-baked functionality to users, and marketing it as if full self-driving is just around the corner, when in fact it has a long, long way to go.

dmitrybrant··on Physicists detect signs of neutrinos at Large Hadron Collider
While neutrinos are not very difficult to generate, they are extremely, astoundingly difficult to detect. Unless we discover a new type of matter that interacts more strongly with neutrinos, we're stuck with cavern-sized detectors that can detect single-digit numbers of neutrinos (out of many trillions), unreliably.
dmitrybrant··on Futurists have their heads in the clouds
My prediction is much less wacky than predicting a colony by 2050.

I think everyone overestimates the public interest and "excitement" over going to Mars. The reason we haven't been back to the Moon in 50 years is that the public lost interest after the ~third or fourth launch, and stopped tuning in to the broadcasts. With ever-improving VR technology, I'd predict that more and more people would be satisfied enough with a VR experience of Mars, and be done with it. The need to physically "go" to a place and claim it for yourself will be a thing of the past.

dmitrybrant··on Futurists have their heads in the clouds
Wait, a colony on Mars by 2050 that doesn't need to be resupplied from Earth? ...lol no.

Strong, strong disagree that there will be any kind of "colony" on Mars by 2050, and my prediction is that we won't even have our first manned mission to Mars this century.

We haven't been back to the Moon in 50 years. We haven't left LEO in 50 years. Surely we would need to build a colony on the Moon first, as a trial for building a colony somewhere that's three orders of magnitude farther away. We are nowhere close to doing this.

dmitrybrant··on Ask HN: How do you manage your personal documents?
I scan everything pretty aggressively, since I hate physical papers of any kind lying around. Documents that are scanned within the last ~month sit unencrypted on a NAS, and organized in the style of "/2021/Taxes", "/2021/Bills", etc.

Periodically I take the current batch of unencrypted files and add them to a VeraCrypt volume, which contains files organized in this way, going back to around 2005. The encrypted volume sits on the same NAS. There have been surprisingly few times that I've had to "search" for an old document in the archives. And when I do, I can just go to the target year folder, and glance through the scanned images, and also make sure to give descriptive names to the scanned files, if it's important.

Once every few months I back up the encrypted volume to a gold-layered DVD disc (The encrypted volume is still nowhere near 4.7 GB), and store it in a cool, dark place.

dmitrybrant··on Simula One – office-focused, standalone VR headset based on the Linux Desktop
Just my personal feeling, but the jitter evident in the video on the website already makes me nauseated. There is absolutely no way that this would be usable by me for any kind of sustained productivity during a work day.

I might be extremely out of touch, but I'm still struggling to understand who is asking for this. In other words, who expects to be more productive with a VR device, rather than a regular laptop or desktop?

dmitrybrant··on Dithered images and websites (2020)
By all means use dithered images on your website for stylistic reasons, but do not use them simply because dithering produces a slightly smaller PNG file.

First of all, no discussion of minimizing PNG sizes is complete without `pngcrush` which applies all kinds of optimizations to the PNG file (losslessly). In fact pngcrush reduces the author's 48kb dithered file down to 28kb.

And secondly, modern compression formats like webp and avif will blow PNG out of the water when compressing any kind of photographic image. Heck, just turn down your JPG quality, and your image will be much smaller, and still perfectly recognizable.

Know when to use the right tool for the job:

PNG -> diagrams, charts, anything with perfectly uniform areas of color and sharp transitions.

JPG/AVIF -> photos, anything with smooth variations in color.

dmitrybrant··on A Soviet Prisoner's View on What's Important
I grew up in the Soviet Union until my family and I immigrated to the US. I have no particular loyalty to "the west", but I can say with absolute certainty that Western culture is objectively better than Soviet culture.

The general feelings that permeated Soviet society were apathy and misery. It was so pervasive that modern Russians fetishize it and even feel nostalgia for it.

There was an excellent little movie from the 80s called Moscow on the Hudson, with Robin Williams, which beautifully portrays the Soviet immigrant experience. Robin Williams' character says the following lines, which resonate with me completely:

"When I was in Russia, I did not love my life... but I loved my misery. You know why? Because it was my misery. I could hold it. I could caress it. I loved my misery."

dmitrybrant··on Cliqz Search Engine is no longer in operation (2020)
...this is from April 2020, and I still have never heard of Cliqz until now.
dmitrybrant··on Microsoft is bringing Android apps to Windows 11
Microsoft really wants to convince you that your phone and your PC are the same thing. But they've failed in the execution of this idea several times now.

The fact that this partnership is with the Amazon app store, not the Google Play store, is a strong hint of how serious they are about this, and how this latest iteration will work out.

dmitrybrant··on Microsoft is bringing Android apps to Windows 11
Absolutely not -- the Amazon app store and the Google Play store are completely different entities. The fact that Microsoft partnered with Amazon instead of Google for app store integration is a strong indication of how serious they are about this whole thing.
dmitrybrant··on Sharing learnings about our image cropping algorithm
This is a very cynical take (I'm cranky from my second vaccine dose), but:

Imagine how much work, how much energy and effort, went into building an ML-based image cropping feature, just because an up-and-coming Designer decreed that a certain specific crop ratio was the most aesthetically pleasing to the human eye...

...so that years later, after countless hours of additional user research, they would just remove the feature because it doesn't work, and award themselves a medal for doing it.

dmitrybrant··on Android Studio 4.2
Well sure, thankfully all these myriad ways of doing the same thing coexist without much issues, since they're all just wrappers around findViewById(). But I just wish they'd settle on a pattern that will endure for more than a single major version of the library.
dmitrybrant··on Android Studio 4.2
All well and good, but only if you're just starting to build your app literally today. If your app was built more than ~6 months before the current iteration of Jetpack/AndroidX/etc, you'll never finish catching up with converting your code to the latest new patterns that they introduce.
dmitrybrant··on A virtual Apple Macintosh with System 8, running in Electron
That's even more bizarre, since that uses the "v86" emulator, which can literally run in a browser tab with one click:

dmitrybrant··on A virtual Apple Macintosh with System 8, running in Electron
I'm not sure why this keeps appearing on HN, but I hope it's some kind of postmodern critique of everything that's wrong with our field.

This is taking Basilisk II (which is already a native app that runs on all major platforms!) and recompiling it into javascript, so that it can be run less efficiently and more bloatedly in Electron. Can we please stop doing this to ourselves?

dmitrybrant··on Tauri: An Electron alternative written in Rust
My god... a 200+ MB install footprint, 200+ MB of RAM usage, requires a beefy GPU just to render its window. How did we get here?
dmitrybrant··on Reforming the Mathematical Language of Physics (2002) [pdf]
Most people familiar with the US patent office will agree that it's totally broken. The reviewers are not scientists, and aren't required to understand what's being proposed in a patent. They simply perform a search for prior art.

As a result, all kinds of pseudoscience has gotten "patented", for example this patent for detecting "tachyonized" materials (you know, materials that have been infused with tachyons, the hypothetical particles that travel faster than light):

dmitrybrant··on Man to pay £25,000 ($34,000) damages over negative TrustPilot review
I'm not sure about that. A sane business would not give in to bullying tactics. Most small business owners I know have probably never heard of Trustpilot, and if they did, would probably consider any kind of fee for maintaining a decent record to be an obvious scam.
dmitrybrant··on Man to pay £25,000 ($34,000) damages over negative TrustPilot review
Well of course they wouldn't advertise these sorts of practices in their pricing plans. But you can get certain hints from some of the verbiage. For example, they talk about "review invitations" -- this is code for review gating, which is the practice of selectively inviting users who are more likely to leave positive reviews.

They also say "Curate your Trustpilot Company Profile Page through ... adding authentic content". The term "authentic content" is code for "positive reviews", because you'll be able to flag any negative reviews as inauthentic.

And of course you can also look at reviews of Trustpilot itself from third parties, i.e. websites where Trustpilot doesn't have a paid/boosted account, for instance: https://www.reviews.io/company-reviews/store/trustpilot

dmitrybrant··on Man to pay £25,000 ($34,000) damages over negative TrustPilot review
Perhaps a bit off-topic, but TrustPilot is a form of near-perfect evil. If someone leaves a negative review of your business on TrustPilot, you can have it taken down... for a measly $400 per month. If you refuse to purchase their premium package, they can prioritize the negative review to be shown above the positive ones until you do. If your competitor hires a review-bombing spammer to add negative reviews en masse, well, you'll just have to upgrade to the next-tier plan.

It's a shocking lack of integrity, but not surprising, given the business model. Anyway, it's disappointing that TrustPilot gets any publicity for being anything credible.

Edit: A nice little touch is at the bottom of their website that says "See what our customers are saying about TrustPilot", with a hand-picked selection of reviews... from TrustPilot! About TrustPilot! Chef's kiss.

Edit 2: This is not to say that Trustpilot's intentions aren't necessarily good, and they may even be striving to provide neutrality. But the problem is that their business model is, by its very nature, antithetical to neutrality. And of course Trustpilot is not the only review site that has this issue, but it's definitely a site where this issue is glaringly apparent.

dmitrybrant··on Just because I have a vertical screen doesn’t mean I’m on a phone
Just a quick note about a very prominent user of vertical screens: Professor Martyn Poliakoff, known for the Periodic Videos channel (which I highly recommend). https://www.youtube.com/watch?v=Oy8ZMFXS_5E
dmitrybrant··on Fujifilm Created a Magnetic Tape That Can Store 580 Terabytes
You mean you haven't been keeping your hard disks plugged into a power source at all times? Say goodbye to your data! /s
dmitrybrant··on It's 2030. I own nothing, have no privacy, and life has never been better (2016)
I have to laugh for two reasons:

- This sounds like an absolute nightmare scenario for me and most people I know.

- The year 2030 is virtually tomorrow in terms of societal progress. Nothing of the sort will happen by 2030. This is like science fiction authors of the 1970s predicting that we'll colonize the solar system by 2001.

dmitrybrant··on Web based Windows XP desktop recreation, built with React
This is excellent, with the very minor detail of the fonts, which look a little off, and perhaps a little too anti-aliased? This seems to be the main issue with all web-based retro simulations of Windows 9x and XP. I'm guessing this is because the default font (Tahoma?) isn't freely licensed? Everything else is spot on, though!
dmitrybrant··on Creating a Slack app that uses fewer resources
Yes, I'm often puzzled by developers who award themselves a medal for squeezing a bit more performance out of an enormous bloated web app, when a native app would be orders of magnitude lighter and faster.
