> It's a video game, but entirely generated by AI

I ctrl-F'ed the webpage and saw 0 occurrence of "Minecraft". Why? This isn't a video game, this is a poor copy of a real video game you didn't even bother to say the name of, let alone credit it.

There is one mention of Minecraft in the second paragraph of the Architecture section, "...We train on a subset of open-source Minecraft video data collected by OpenAI[9]." I can't say whether this was added after your comment.

> 1 protein plus 1 electron

Assuming that was autocorrupt. :)

But 1+1... isn't that just normal hydrogen? Is the point that it's atomic, not H2?

kiloDalton · 2 years ago

I wish I could blame autocorrect. Just had proteins on the brain and typed the wrong word. If it wasn't obvious, protein --> proton

How much of a progress is this? Anyone here that can add insights?

kiloDalton · 2 years ago

The paper isn't about splitting water to yield hydrogen and oxygen gas which would be useful for energy applications. It's about a new way to make radical hydrogen (1 protein plus 1 electron) which is useful for synthesizing some organic compounds. It will be helpful for synthetic chemists and will make it easier to explore hydrogen radical chemistry. It may replace some processes that currently require transition metal catalysts, especially Samarium which is a rare earth element.

What has the square footage and amenities for single family homes done over the same time frame? You aren't comparing apples to apples...

Not to mention the average household size (number of people) has been dropping...so the square foot per household member is up drastically...

Not an expert, but I did read the article. The point of the "Case-Shiller" metric is that it is computed on the basis of the same exact property changing hands in different time periods. That way it controls for trends in the product pool.

Or as the article put it: Case-Shiller requires two transactions for the same house,” Lazzara said... It controls for the variability in the quality and size of the homes sold from year to year by measuring the change between houses that sold in one period with the prices of the same houses when they last changed owners. “The repeat sales mechanism is a way of adjusting for the mix of product so that you really are getting an apples-to-apples comparison,” Lazzara said.

So are the mp3 files not the same as what the author uploaded? I could imagine weird organization for tracks from the service but for self-uploaded data I would be surprised if they didn't just give them back the same.

The article never mentioned how this showed up in the GPM app itself which feels lacking.

Otherwise a nice article but it reminds me why I long ago gave up on media metadata organization. So much work, so much mess...

In the case of lossless files, the takeout files are empathically not the same files that were uploaded. Google Music would allow a user to upload lossless FLAC files, but internally it converted them to 320 kpbs MP3 files. So, GPM certainly transcoded a portion of uploaded files. I'm not sure to what extent it left files alone if they met Google's formatting specifications. Perhaps someone else knows.

I remember enjoying E.P. Thompson's take on "Time, Work-Discipline, and Industrial Capitalism" in college. He has a lot of interesting commentary about how technology in the form of accurate timepieces played a role in our concept of labor. The article is here behind a paywall (https://www.jstor.org/stable/649749). Anyone with access to a search engine can likely find a free copy ;).

It's worth noting that this study does not include azithromycin in the treatment regime, as was the case in the Raoult/French study.

The French study, problematic in the extreme but still promising, claims a large synergistic effect of using both drugs in combination.

Also, unlike the French study, this one appears to be at least controlled, but possibly not blinded.

kiloDalton · 5 years ago

I think this counts a double blind trial. From the top of page 4 in the article: "Randomization was performed through a computer-generated list stratified by site. Treatments were assigned after confirming the correctness of the admission criteria. Neither the research performers nor the patients were aware of the treatment assignments."

lutusp · 8 years ago

As usual in articles of this kind, the article's content contradicts its title. The study doesn't show that "loneliness raises alcohol tolerance," it shows a correlation between two measured traits.

In studies like this, two effects are measured and found to be correlated. For lack of evidence, an assertion about cause can only be conjecture.

kiloDalton · 8 years ago

As I understand it, this article is about a controlled experiment. In which case there is no confounding and therefore correlation implies causation.

"Other than a few minor nitpicks"

That would be a nope. Gadfly doesn't meet my needs and seems to have stalled in development, so I use Matplotlib via PyPlot, but Matplotlib is a bit maddening to work with. I heavily considered attempting my own plotting library during grad school but couldn't find the time for it :/

(Although I will say that Convex.jl makes up for all the pain of not having a good plotting library...)

kiloDalton · 9 years ago

It's worth noting that convex.jl is developed by the same folks as cvx (matlab) and cvxpy (python). They all provide access to the same solvers with similar abstraction and usability.
