I remember to this day the exact location I was when being introduced to construct hypercubes, to the exact bench in our uni cafeteria. It changed my understanding of multidimensionality completely.

They really do a lot to correct for bias, but is it enough?

I would suspect that a prosperous and thereby complex economy also has more resource to discover or document inscriptions. While they talk about researcher bias, they do not really mitigate this.

And yes, I searched the article and the extensive additional material.

Still a valuable contribution.

Re:You could have invented PageRank on Wednesday August 26, 2026 @11:26AM (#49450852)
PageRank is fascinating, since it is so easy to explain.

Yet, this is not even half the work. It like a third of the way.

Before you could have invented PageRank, you must think in graphs. That is possible in 1996, but not as widespread as today.

After you invented PageRank, you still need to deploy it. Again, possible but challenging as well. Is Python performant enough in 96? Can you afford more than 4MB RAM?

At least Lego will not sue you for using their bricks to build a server rack in 1996.

> Since John Hammond "spared no expense", it is fair to say he picked 1GiB version at $3,598 a piece. That would give them 7 GiB of storage for a 2026 equivalent of $33,223.70. In 2026, 7 GiB of HDD would cost $0.49.

Did anyone ever try to estimate storage inflation across time? 7GiB could be one or two pc games in 2026, in 1992 one games likely was 1.4MB.

Re:I'm a USB-C Maximalist on Wednesday July 15, 2026 @03:16AM (#48917313)
I use USB to teach students about European Union regulatory policies, because this is one obvious standard they all can connect to. (Pun intended).

Throughout the years they were cautious when it was introduced, thankful after it was established, and now they are too young to know any other world.

And yes, USB as main connection standard was driven by Apple. But USB as main charging standard was set by the EU.

> This couldn't have happened 10 years ago.

I agree. Something similar could have happened 30 years ago, and it did, see Transport Tycoon (or a lot of early games). But from 2000 to 2020?

Re:Too many R packages: CRAN is inundated with submissions on Wednesday June 24, 2026 @09:38AM (#48659640)
I see "AI and R" in three perspectives:

First, usage: Using R for our undergrads in time of LLMs is brilliant. ChatGPT slops out working code for their needs. Not pretty but works better that in 2022.

Second, development: Mastering R is hard, because its kalkül. Tidyverse mediates some of it, but still. This is the perfect breeding ground for slopification. Lets see.

Third, errata: I would love to know the percentage of science built on R to this day. I mean insights and analysis supported by it and it vast packages. What if somewhere, deep down in the stack there is an ancient bug that dented all of this? I think AI might help us here, or review slop will negate this?

Things lost to time: The Minolta Dimage A1 had contacts for detecting when gripped, so it could ready itself without any button pressed: https://en.wikipedia.org/wiki/Minolta_Dimage_A1 (You see it in the pic, but its not described in the article).
Confounders are included and therefore controlled for, and causality can be assumed since the DV is an event/hazard. This is also the reason you end up with the seemingly high average...
Why is Nvidia so central to LLMs? Because they embraced ML a decade ago. Apple did as well, machine learning is central to so many things in the iPhone. Its not so surprising then, that a strong showing in ML sets you up good for LLMs..

Its been years since I felt urged to congratulate someone for their "webdesign", but this is really good. No boring glossy landing picture, but a distinct claim, and the the before / whoisit / after Element is unique, in a good way.
Re:Kidnapped by Deutsche Bahn on Tuesday December 30, 2025 @10:02AM (#46433954)
Kidnapper is likely not Deutsche Bahn but a regional subsidairy.

This is an effect of privatization gone wrong, with the national service, the infrastructure, the regional services (each), the network (not in infra), cargo and then some (sub)companies split for privatisation and an IPO that never happened. The highly segmented network is not digitalized in to any standard, so regional trains have to operate in policy frameworks and network cells that favor long distance trains. Its utter chaos on a daily basis.

Re:An SVG is all you need on Thursday December 11, 2025 @05:51PM (#46238444)
The reverse is kind of true: In the beginning, SVGs were not really an option since it lacked adoption across all major browsers, or more specifically its integration was very heterogenous.

So a SVG you authored 20 years ago for some browser will likely work everywhere today.

Solar sun roofs for ICEs were a thing 20 years ago. Solar was able to ventilate your car on sunny days.
Not so sure if Google "still controls 90 of web search" and if this means what it meant three years ago. Many prompts could have been a web search. The metric of interest must evolve here.
The article states that the purpose of this is "lost to time". I can image that by now its function is equivalent to a "brown M&M clause".
Zoom is a thing in Germany.
The early version of Google Play Music asked for your MP3s, so you could have them in the cloud for streaming. I guess they did this for a baseline of data and music and now I wonder if this was an elaborate hack to circumvent legal implications. Should have read the terms back then.

That would be an interesting story!

How is the photo quality? I love the pictures from the old 12MP sensor + Googles software, but I understand this is not in Lineage?

Is this a Nokia Watch or rather a Nokia Cuff?

Most sports would profit from a deeper understanding and application of statistical inference. Or even of descriptive statistics. The fun lays in the operationalization, a step most applications of AI will likely omit, since AI will work out the dimensions of the data by itself.

Boxing for example could calculate the amount of kinetic energy brought to the table and how much of it landed or was sidestepped. How much was absorbed? Not easy to do, but also not impossible.

Great work, it really captures the feeling of Marble Madness. Its maybe to deep of a thought, but I really fancy the spin of the marble, something that the original was not conveying as fancy as your version does.
Re:The Frankfurt Kitchen (2011) on Thursday October 31, 2024 @04:10AM (#42004481)
There is also a German word "Frankfurt bath", when you place the shower in the kitchen, with some of these arangements still present in flats today.
My first job was to write news to teletext for German public broadcast. It required the author to compact even complex news into essentially two old tweets (I think around 300 characters) and deliver some context. Very good training!
Re:Stepwise selection of variables in regression is Evil on Tuesday September 17, 2024 @10:58AM (#41568265)
There are many concepts called stepwise regression, its so weird that statistics, as a field, are so bad in delineating concepts.

I teach my students what you see in most social science papers, and in the light of the article at hand, I would call it "stepwise presentation of multivariate regression".

When it comes to the task of explaning, I think presenting different models, with a discussion what your pick is, provides good value to readers.

That said, I agree to the sentiment of the article but not the wording. "Blind" or manipulative stepwise deletion will decrease falsifiability of your work. That should be more provocative to scientists than evil.

Re:Closing factories will not be enough to save Volkswagen on Thursday September 12, 2024 @08:38AM (#41520162)
This is exactly the Volvo / Polestar philosophy. There is a Decoder podcast with their CEO about just this sentiment.
Re:Closing factories will not be enough to save Volkswagen on Thursday September 12, 2024 @08:36AM (#41520136)
VW has Chinese joint ventures since decades. They already sell their "jv-EVs" in China, just not in Europe. I think in that regard, they are undecided wheter these products will meet brand standards in Germany.

VW as a brand went upmarket in the 2000s, with Skoda / Seat / jvs going for the meat. They became world class in repackaging and rebadging, and EoS helped a lot. That also made them kind of conservative in engineering, since everyting everywhere is super path dependent. You could find the same switch in a Seat Arosa and in a Bentley.

They are not trying to make a good EV, they try to replicate their ecosystem as a whole and that needs EoS above anything.

Read the abstract and then imagine someone or somebot would study your medical condition in similar depth. This is myutopia.

This is a expertly crafted narrative of presumably complicated research.
