dilippkumar··on The Nitpicks of Power, Part I: Exploding Forges
Wow. Such a unique experience.

What was the whole process like? Did you see anything on set that was amazing but didn’t make as big of an impact on screen?

dilippkumar··on Google is screwed, even if it wins its antitrust case
> Furthermore, the product that made their name is thoroughly lost. I dread Google Search today. If I found something on Google yesterday, I have no idea if I'll be able to locate it through the sea of blog SPAM and SEO garbage tomorrow.

I’ve had pretty good results with kagi.com

YMMV.

dilippkumar··on Sexual loneliness: A neglected public health problem?
I haven’t checked, but my intuition is that removing photos reduces the available bandwidth, not increases it.

Perhaps a dating app that only allows photos taken with the app, that ensures no filters or edits were done to the image probably increases the bandwidth. But then, that’s an antifeature - I doubt people would want to use such an app.

dilippkumar··on Sexual loneliness: A neglected public health problem?
I’d love to start a conversation here about attempting to solve this in a very narrowly defined place as an experiment. Since this is HN, I nominate San Francisco.

My hypothesis is that the bandwidth required to present oneself and assess another person is larger than what fits in the self_awareness -> profile_creation -> dating_app_algorithm -> profile_selection -> personality_model_creation -> model_evaluation pipeline.

We already know that a lot of communication happens non verbally. There are other signals we care about: do this person’s friends like them, etc. There are questions about compatible value systems and one’s relationship to risk, money, independence etc.

If there is a technology solution here, I doubt that it looks like a collection of profiles.

Anecdotally, online gaming and niche reddit communities have a somewhat high success rate at creating friendships. One possible way to use this model is a dating app that lets you solve puzzles with another person real time instead of swiping on profile pictures?

I don’t know. I’m throwing ideas here to get a conversation started.

dilippkumar··on US Marines defeat DARPA robot by hiding under a cardboard box
Presumably, a plywood wall painted to look like a road to a camera will still look like a wall to the radar/lidar.
dilippkumar··on US Marines defeat DARPA robot by hiding under a cardboard box
Unfortunately, this will not work for autonomous driving systems that have a front facing radar or lidar.

Afaik, this covers everybody except Tesla.

Looney Tunes attacks on Teslas might become a real subreddit one day.

dilippkumar··on UK proposal to criminalize “sophisticated encrypted communication devices”
So, all you have to do is make these devices be “mobile phones” and “commercially available”?

Is selling a device on Ali Express enough to qualify?

dilippkumar··on Apple offers $970 in trade-in value for $52,199 Mac Pro
Are we bidding?

I bid $990

dilippkumar··on Reverse engineering a neural network's clever solution to binary addition
> designed by John von Neumann.

I can strongly recommend an excellent biography:

The Man from the Future: The Visionary Life of John von Neumann by Ananyo Bhattacharya

I knew of von Neumann because his name shows up many many times when studying computers. But I had no idea he had several equally monumental bodies of work in such a wide range of subjects.

It’s that rare biography that helps understand the history of multiple different disciplines: quantum mechanics, game theory, computer science and more.

dilippkumar··on U.S. Auto Sales in 2022 Worst in over a Decade
Anecdotal data points here, but four different people I know wanted to buy a new car the past year.

Nobody found cars on lots.

One guy bought a Tesla literally because he could buy a car and felt waiting a few months for delivery was his only real option.

Another couple had a minivan shipped all the way from Nebraska.

The remaining two haven’t purchased a car. They would rather wait till cars they like come back to lots.

These played out over Q2/Q3 2022. Not sure if the situation is different now.

The automobile industry did this to themselves. I’m not a Tesla fan, but I see them winning by literally being the only manufacturer who is able to deliver cars to customers these past years.

(Yes, there are a ton of caveats and my sample size is small and doesn’t reflect *reality (TM)* etc etc)

dilippkumar··on French startup unveils new residential thermo-acoustic heat pump
> The heat pump has a coefficient of performance (COP) of three to four, which means that it produces 3 kW to 4 kW of heat for each kilowatt of power it consumes.

This is setting off some massive BS alarms in my head. Why is this not violating conservation of energy?

dilippkumar··on Google's search is borderline useless these days – what alternatives exist?
My experience with kagi.com has generally been positive. I don’t use them often because I browse exclusively in Safri in private mode - the search defaults to Google and there isn’t a good way to switch it to Kagi for me.

Give it a try. I often find what I’m looking for within the first few results.

dilippkumar··on No Other Options: Newly revealed documents depict Canadian euthanasia regime
I can recommend Airthings Wave. It’s a useful product to have around.
dilippkumar··on Archaeologists ask Netflix to reclassify Graham Hancock’s docuseries as fiction
> If these societies were that advanced, would they not have figured out a fraction of the things that we have in modern times?

The interesting question from Graham Hancock’s books is along the lines of: “If these societies were that advanced, how would we know?”

Until Gobekli Tepi was discovered, there was no evidence that humans did anything other than bang rocks together till the end of the last ice age.

We can not use radio carbon dating on inorganic material. We can’t look at a stone monument and determine it’s age purely by looking at the stones. For big monuments, the best we do is “the oldest thing we found here that shouldn’t be here unless someone put it here is xxxx years old. Therefore this is at least xxxx years old”

Graham Hancock and others pointed out that several monuments were aligned astronomically if you assume they were built at the end of the ice age. We didn’t believe anyone could have built the monuments that early because we hadn’t discovered Gobekli Tepi yet.

Basically the current problem isn’t absence of evidence that people were advanced back in the ice age. The problem is determining what is evidence and what is coincidence - and a lot of things that should have been evidence were brushed aside as coincidence because that determination was done pre gobekli tepi.

dilippkumar··on Ask HN: Do you measure and/or mitigate CO2 in your living space?
+1 for Airthings wave.

I learned a lot about the ventilation situation at my place by tracking CO2 buildup. I now know that the time I should leave a window open to get CO2 levels indoors to approximate equalize to outdoor levels is 10x longer than what my intuition suggested.

I also discovered that every time I felt the air was “stuffy” and I needed some fresh air, it actually corresponded to a spike in VOx levels. When mom was visiting over summer, we discovered she is also sensitive to VOx levels.

This is my first winter with airthings wave. I’m curious to see how humidity levels are impacted by trying to keep my house warm.

dilippkumar··on OpenBSD: Immutable Userland Mappings
I’m currently using OpenBSD as my only operating system on my Thinkpad X1 carbon (gen 7).

Wifi works just fine. I remember that the wifi drivers aren’t part of the base install system for licensing reasons, but they provide a very simple tool that will download it and set it up.

Generally, with openBSD, if something is supported, it is supported correctly. My go to example is that my keyboard backlight controls work even from the tty terminals.

But also, if there is something that the developers don’t think they can support correctly, they don’t hesitate in removing it entirely from the OS. They removed Bluetooth support for example.

It’s not for everyone. But for me, I love the idea that I can trust my primary computing environment because the developers care soo much about the little details.

dilippkumar··on Ask HN: How do you deal with the end of globalization?
Since this is HN, here is a book recommendation:

The End of the World Is Just the Beginning: Mapping the Collapse of Globalization by Peter Zeihan

I’m going to add the usual disclaimers here about everything that comes with listening to a guy who has been predicting doom for a decade. He is very entertaining though and he has some unique insights and some unusual data comparisons - it’s fun to read.

To be fair, he did predict events in Ukraine a few weeks before they happened [1]. That counts for as much credibility as one can have with a title of “geopolitical strategist”

dilippkumar··on Ask HN: Ads triggered by WhatsApp “end to end encrypted” messages?
I would love to see a control channel in this experiment here.

Pick two topics every time. Send one topic to your wife on Whatsapp. Write paper messages to your wife about the other topic and give it to her.

Track how often you see advertisements for topics in both channels. A significant difference in any one channel will be worth sharing.

dilippkumar··on FreeBSD Cope with WiFi Fuckup
Unrelated: What's the current state of FreeBSD on a laptop? What's the recommended hardware setup? Is it something I'd feel confident travelling with as my primary computing machine?
dilippkumar··on The most secure cloud is your computer
Is this a Cryptonomicon reference?
dilippkumar··on Reducing methane is the fastest strategy available to reduce warming
> Even completely eliminating methane will not reduce warming, it will only reduce (slightly) the rate of acceleration of the rate of warming.

Can you share some references?

dilippkumar··on John von Neumann – The Role of Mathematics in the Sciences and in Society (1954)
Book recommendation:

The Man from the Future: The Visionary Life of John von Neumann by Ananyo Battacharya[0].

It’s a really good biography of John von Neumann. The book follows both his life and the impact of his work carried on by people who came after him. I can recommend this book.

dilippkumar··on Hardening macOS
> There is no half-decent MDM out there. Only shit ones but workable like Jamf.

Can you please elaborate? What problems would you pay to see solved in MDMs?

dilippkumar··on Physicists link two time crystals in seemingly impossible experiment
As an outsider who enjoys a certain flavor of conspiracy theories, your confusion about a timeline involving a professor investigating delayed choice experiments tickles me.
dilippkumar··on I Started Journaling (2019)
I have found that journaling in Day One and then having my journal entries printed and bound as a book every year (Day One offers this service in their app) has been a good trade off.

Writing on my phone, adding pictures, copy-pasting passages from the internet are easy to do.

Once printed and bound as a hardcover volume, I know it’ll outlive the app, my phones and probably myself.

dilippkumar··on What did Earth look like X million years ago?
Not quite what you are looking for, but the Malazan series has some stories spanning extremely large time scales through which multiple intelligent species evolve into existence and fade away.

It is by far, the best series I've read. Book 1 is hard to get into, and doesn't reward the reader as much, but stick with the series. It's worth it.

dilippkumar··on Congress urged to ease immigration for foreign science talent
The relevant law in question is explicitly country of birth. Nationality doesn’t apply.
dilippkumar··on I made a virtual bookshelf
I see a lot of Demon Cycle books. Are they good?

I’m finishing up on the last few Malazan books, looking for recommendations on what to read next.

dilippkumar··on Brendan at Intel.com
> yelling at hard drives in Sun's data centre

I didn’t expect this to be so… literal.

dilippkumar··on Using Asahi Linux as a developer workstation
OpenBSD 7.1 that released today also had a lot to say about M1 support. Does anyone have experience running it? How does it compare to Asahi Linux?
