mandelken··on Generic GPU Kernels
Should have (2017) in the title.

Indeed cool to program julia directly on the GPU and Julia on GPU and this has further evolved since then, see https://juliagpu.org/

Here's an excerpt from my chat with Teddy just now:

You (20:26): Teddy, do you have lithium ion batteries inside you?

Teddy (20:26): Yes I do

You (20:26): Can lithium ion batteries malfunction?

Teddy (20:26): Yes

You (20:27): What happens when lithium ion batteries malfunction?

Teddy (20:27): The human dies

mandelken··on Nuclear fusion is close enough to start dreaming
Thanks.

Note it’s an opinion piece published on bloomberg, not an actual bloomberg article.

mandelken··on Mammals dream about the world they are about to experience before they are born
Perhaps it’s more than just calories or energy intake, but as well doing the breathing, immuno responses, digesting, filtering blood etc. for both mother and baby?
mandelken··on Regularization is all you need: simple neural nets can excel on tabular data
GBDT have their own set of hyperparameters such as learning rate, number of trees, min samples per bin, l0, l1, etc. So you could definitely also create an appropriate cocktail to optimize on, although GBDT are typically more robust wrt huperparameters.
mandelken··on How to circumvent Sci-Hub ISP block
Probably because for written text the words identify the content while the hash relates more to the digital carrier format (pdf vs epub) and id number can change between publications, countries, etc.
mandelken··on It's time for us in the tech world to speak out about cryptocurrency
From my experience this is true for bank clients in Belgium, the Netherlands, France, Austria and Spain (but the latter only at your own bank).

When I withdraw money with my Belgian debit card in the Eurozone at any ATM (including Berlin), I do not pay any fee. And this is true for all major Belgian banks.

Of course, if your account is not in the Eurozone (US?) or denominated in EUR, or through a basic credit card (visa) then usually a fee would apply.

Depends on your background and experience, I guess. In many European countries ATMs are free, even outside your own country. It is considered an elementary part of the banking service that you don't have to pay to withdraw your own money.

Clever analogy. Let me quickly give some background on actual the use of gold as a store of value, besides the obvious point that gold does not rust (decay) and that it is somewhat rare.

As you know, gold is also shiny and has been used for jewelry for thousands of years in many cultures. Some anthropologists have reversed the causality of value and jewelry, arguing that gold is precious _because_ it is used as jewelry. Indeed, in many cultures different types of jewelry [1] were used as a basis for currency (as in unit of accounting).

Therefore, one of the most basic human features, dressing up within a social hierarchy might be at the basis of gold and currency.

I don't see any such use case for cryptocurrencies (yet).

[1] besides pearls, beads, necklaces, it could also be rare make-up material or even feathers. I recommend the work of anthropologist David Graeber in his book Debt: the First 5000 years.

Could you provide some background (or links) to your claim (I thought the inventor(s) of Bitcoin were anonymous)? Thank you.

TL;DR [CITATION NEEDED] ;-)

Wow, you can actually pay your bus fare and phone bills in Brazil with crypto? That sounds either very impressive or totally unbelievable.

I could not find anything on Google, so if someone could you link/cite to some actually used examples (I guess apps or utility website?) that would be very helpful. Sincere thanks.

mandelken··on It's time for us in the tech world to speak out about cryptocurrency
Wow, blast from the past! I actually got a check from one of those pay per hour ad services more than 20 years ago, and to this day it's still the only check I've ever received :-)

(It was 15 USD so costed almost as much to cash in Europe as it was worth)

mandelken··on It's time for us in the tech world to speak out about cryptocurrency
Thanks for sharing your point of view.

What is unclear to me, is how these remittances work in practice. I get that in the US you can exchange USD to Bitcoin with a credit card and then send that to a person in, say, Venezuela (or share the wallet password). But how is it converted back to Venezuelan Bolivar? I can't imagine you buying a pizza with bitcoin in Caracas.

Side question, why do you write your years with a leading zero? I've never seen that before and it has quite a cognitive strain for me.

mandelken··on The Google Nest Hub is first commercial Fuchsia device
No, most private companies are not monopolies (although many would not mind I guess).

It seems online advertising has a strong network effect[1], where website owners use Google ads because that's where most advertisers are and advertisers use Google ads because it has most reach (and therefore tracking). This naturally creates a monopoly, just like with Facebook, twitter, LinkedIn, AirBnB, Uber etc.

mandelken··on Android's new Bluetooth stack rewrite (Gabeldorsh) is written with Rust
Yikes, that sounds pretty harsh. So how would a new player be able do enter?

I thought only the hardware could be patented, not the software, and so SDR would level the playing field, but that's perhaps too naive?

mandelken··on Android's new Bluetooth stack rewrite (Gabeldorsh) is written with Rust
Care to expand? Is that why Software Define Radio is still so much a niche and expensive?
mandelken··on The Transformer Network for the Traveling Salesman Problem
You could try it on a quantum computer, but you'll have to wait a decade (at least) the see one with enough bits to solve a problem of practical size ;-)
mandelken··on Twitter shuts down account of Sci-Hub
I doubt that. Giving out (free) money indiscriminately will not immediately pass a direct popular vote.

A good case is the Swiss referendum on universal basic income a few years ago that was voted out. And the Swiss have the money to pull it off if they wish.

mandelken··on An Invisible Tax on the Web: Video Codecs (2018)
Perhaps in China?

I support your sentiment, but most countries with strong software communities appear to have strong software patents (US, EU, Taiwan, SK). Maybe the only outlier is Russia (and possibly India)?

mandelken··on Ask HN: What's the best paper you've read in 2020?
Especially the figures do such a great job of illustrating and clarifying the subject. Wonderful paper!
mandelken··on “I just woke up one morning and it struck me that I was a murderer. so I quit.”
It is unethical because the US is the only country to have used the atomic bomb and by far the largest missile threat all over the planet today.

In contrast, Iran, China and Russia do not on a daily basis assassinate civilians with missiles.

mandelken··on “I just woke up one morning and it struck me that I was a murderer. so I quit.”
I think he's referring to putting satellites into space for civilian use, but I could be mistaken.

mandelken··on Magic hat leaves behind a transformed craft beer industry in Vermont
Europe is far too big a geography to pin down beer, it's mostly concentrated in the UK, Ireland, Belgium, Netherlands, Germany and Czech where you find the right climate for the ingredients and hence the beer culture (of course you find beers in France, but they have a larger wine culture).

The differences between them are also huge with Irish dark stout, British pints without collar, German lager only made from basic ingredients, Belgian specialty beers, etc.

The effect of tradition and culture makes almost every beer in those regions taste perfectly decent and some very good, while in the US most are piss-water and some might indeed be very good.

With Bud Light still having the biggest market share, I believe the piss-water jokes still stand today.

mandelken··on A new weapon in arbitration: sheer volume
As a European, reading these articles on arbitration, no-compete, required licenses, 'right-to-work', tipping, "gig work", firing over zoom, and so much more, it seems U.S. workers could really use some collective bargaining? Here unions are the obvious century-old solution to improve working conditions, why don't workers organize there? Are we just lucky here, like with universal health care?
mandelken··on A startup is building computer chips using real neurons
If you can recreate (part of) a human brain through stem cells or any other way , then why would this not be a human? People with half a brain (after an accident, say) are still people. Cloned people (twins) are still people. Babies born from artificial insemination are still people. It's not up to these researcher to determine what is allowed to do with human brain tissue. Very troubling and unethical
mandelken··on Cloud AI Platform Pipelines
I wonder how this might work with NLP workflows that use a custom embedding? I have not found a documentation or blog describing such a memory intensive step in the pipeline without running a custom instance/docker. In that case I can just run the whole model on that instance..
mandelken··on Ask HN: A New Decade. Any Predictions?
I would happily take the other side of the bet on EVERY item here! But I do appreciate your boldness in predictions.
mandelken··on How the Library of Congress Unrolled a 2000-Year-Old Buddhist Scroll
> In 2005, conservators received the scroll in a Parker Pen box on a bed of cotton.

Surprisingly light on details of its origin. Part of the US war loot from Peshawar perhaps?
