> Science needs models based on mechanistic understanding of the underlying phenomena. A model that merely predicts is useful for engineers, not scientists

I'm not sure I agree. I'm aware of quite a bit of supercomputing time that is spent doing lattice QCD calculations (which apparently some scientists find useful), and though I'm no quantum physicist I'm pretty sure there is not much of a "mechanistic understanding" in QCD. I think your claim also doesn't apply to a lot of social science - psychology has a lot of functional models, but I don't think there are many mechanisms described.

I'll also state that modern science that doesn't require any engineering is pretty rare nowadays, so if a predictive model helps engineers that can then help scientists, the model has been helpful to scientists.

Ohm's law existed long before there was a mechanistic description behind it, and though it is mostly used for "engineering," I feel confident that a lot of scientists in the 19th century found it useful.

I'm constantly surprised how three Sci-fi classics together describe the dimensions in the world where we live in. These books combine together to form the parameter space for our world.

1. 1984 by George Orwell: totalitarianism, telescreens, thought police, doublethink, Newspeak, Big Brother and the cult of personality

2. Brave New World by Aldous Huxley. Using medication to stay happy, psychological manipulation and conditioning, class hierarchy based on intelligence (or perceived ability).

3. The Space Merchants by Frederik Pohl and Cyril M. Kornbluth. Huge international corporations de facto run the world. States are their front. Advertising is the best paid profession (FB, Google). Ads and products are very addictive and aggressive. Advertising agencies select the new president. People are fooled to believe that quality of the products is constantly improving their life while basic things needed for life are becoming more expensive and out of reach for normal people.

Isn't the title incorrect? As in: it does orbit around the sun, but the center does not coincide exactly with the center of the sun. Or maybe there are other used definitions of the term "orbit around"?

There is absolutely nothing beautiful about it and there is negative utility in allowing it to proliferate. It actively causes resource usage and damage that is unnecessary and totally avoidable.
I didn't imply being anti-trump was sufficient for making one center-left. My argument is that a political wing holding the White House and Congress is insufficient evidence for a countries counterculture being precluded from coming from that wing.

The fact that establishment type Republicans (whether in office, writing op-eds and books, or simply voting as normal citizens) are also anti-Trump, strengthens my argument.

----

There seem to be at least five possible candidates for a counterculture today: progressives, center-left (the cosmopolitan, coastal, etc.), centrists, establishment republicans, and the portion of Trump supporters that are 'alt-right'(I assume the alt-right populate 4chan and 8chan quite heavily).

The disagreement here seems to be over whether the fact that Trump is in office and the GOP holds the senate, precludes the alt-right from being the countries counterculture. I can see a number of different ways this could evolve argumentatively.

Regardless, to preclude the alt-right from being the counterculture on the basis that the GOP has the White House and the Senate, requires assuming Trump is alt-right, some non-trivial portion of Congress is alt-right, and that for some additional reason these facts preclude the alt-right from being the counterculture.

Just like people keep on waxing how innovative Tesla is, when in fact electric cars were thoroughly explored more than 100 years ago so Tesla is mere copying the innovation of others.
I second creating a large high quality dataset to advance AI. It would be especially effective when combined with a competition - Imagenet competition jump started DL revolution in 2012, and currently there’s no obvious successor. What’s lacking in AI is models with “common sense” and a “world model”. A dataset/competition to develop such models could cause the next AI revolution.
As mentioned in the article, Amazon does have "Editorial recommendations" that appear for certain queries, which are basically buying guides written by third parties.

An Expert on Concentration Camps Says That's What the U.S. Is Running
Whenever a group seeks to get their way by interfering with the rights of others, because what they are trying to achieve is "too important" to worry about such "petty" concerns as people's right to freely travel, engage in commerce, and generally pursue happiness - it's time to watch out. Recent (past 200 years) history is filled with example after example of how tragically this ends.

This is not civil disobedience. This is actively attacking other people and putting their lives at risk.

Groups such as this are not doing anything noble, and they do not deserve any admiration, respect, or protection.
> What you should be saying is not "can be represented exactly" but "can be represented identically in decimal"

No, exactly, if the decimal was non-periodic such as 0.1 it is exact, it is exactly representing 1/10, but base2 cannot represent 1/10 exactly.

> There is nothing inherently less accurate about binary floating-point representation than decimal.

Yes there is, and this is the part that most people do not intuit, this was the entire point i was making about the deceptiveness of formatting masking representation error of the fractional part in my original comment... we are not talking merely about precision, but the representation error which is dependent on the base:

base10 base3 base2
1/10 yes no no
1/3 no yes no
1/2 yes no yes

For the first decimal place in base 10 (i.e 0 through 9 denominators of 10) you will find only 1 out of 10 possible fractional parts can be represented exactly in IEEE 754 binary. IEEE 754 actually specifies a decimal format, not that it's ever used, but if you were to implement it you would see these discrepancies between binary and decimal using the same format at any precision by noticing a periodic significand in the encoding when the source representation is non-periodic.

This is not a deficiency of IEEE 754 per say, but the entire concept of a decimal point in any base, which makes it impossible to finitely represent all rational numbers, kind of making them pseudo irrational numbers as a side-effect of representation... the solution is to use fractions of course.
Yep, CUDA and Vulkan Compute are such a waste in HPC, thankfully ML research is doubling down on threads.
You were the one who introduced GPUs on low-end embedded chips as an argument. HPC is a slightly different world.
It seems like any distributed system that involves any cryptography these days is being called a blockchain. The Vice article is simply wrong. Yes, it's a great idea to use a chain of hashed timestamps+data to prevent data from being tampered with later. People have been doing this with logs for ages.

The NYT timestamp system doesn't meet the blockchain definition, at least so long as the word has any real meaning. This point is often debated, but my take is that without also featuring some kind of consensus mechanism to order the writes in a specific manner, thus preventing double spending, then the protocol shouldn't be described as a blockchain at all.

A timestamp service (as opposed to a blockchain) is good enough for the goals described in the article. There's no need to enforce strict ordering of transactions because there's no spending. It's just assertions of some fact at some time. So all that's needed are a few reliable servers run by different parties that will log the data. If one of them cheats, it is detectable.

Knowing who is behind the private keys signing the assertions is a far more important problem in this kind of system, and blockchains don't help that one bit.
With respect to the galaxy's frame, sure. With respect to the earth or sun, not so much.

Some random thoughts:

- IE vs Chrome dominance is comparable but not equal. One was closed source and stagnant, the other open and constantly evolving.

- “What if we all contribute to the same code base” ignores that not all priorities are aligned. Apple is a lot more focused on user experience and battery life while Google is all about moving the platform forward, see Web Worker conundrum for example.

- Browser are a lot more complicated now than they used to be, so creating anew from scratch is harder. But the Web is also a lot better documented (edge cases specified) and with more open implementations to get inspiration from.
> It's certainly not a fair comparison to look at these issues per capita. [..] Each country should be responsible to make their territory carbon neutral

You want to shift the goal post to territory instead of population? Sure, lets do this. Wikipedia already has a nice sortable list ready for us [0], with the UK at 1,564, nearly 50% worse than China at 1,133 t CO2/km²/yr.

So, how do we want to define a next target, that allows us to keep telling ourselves someone else is the actual cause of the problem instead of us? GDP/Co2? Scientific papers / Co2? Top 10 watched movies/Co2? Options are unlimited, so I'm sure we'll find something in the end. But maybe we should actually verify whatever we propose doesn't also make us look like the bad guys, since constantly shifting the goal post kinda makes us look like fools.

Well, most of the people who talk about how the white cis straight men have all the power don't seem to believe it either. They keep on calling for all the supposedly white cis male controlled tech companies to police everyone's speech, and even for the white cis male police and government to step in, confident that all that policing will follow their own supposedly-powerless views and stamp out those of their supposedly far more powerful eneimes. The very idea that it might go the other way is seen as so absurd that only a concern troll trying to help the other side would suggest such a thing.

> After studying pharmacology and medicinal chemistry, I lost a lot of faith in our current pharmacological medicine.

My reaction was just the opposite. There are so many aspects of physics or other physical sciences that we take as basic knowledge and learn in grade school, but which were discovered years ago by some of the greatest thinkers of the past. It’s deceptively easy to wonder what it would have been like to live back then when the science was young and discoveries seemed more readily available. When you didn’t need to build a massive supercollider to validate theories. Of course much of this thinking is probably a fallacy... hundreds of years from now people will think similar thoughts about where we are.

And yet medicine quite clearly seems at this earlier stage. Think about how far we’ve come in just the last century... we’ve only known about antibiotics for 100 years and the structure of DNA for half that long. That’s not a reason to be dismissive, medicine right now is in its early days and the people doing the research are pioneers. Medicine today has so many opportunities for smart people to contribute.

Phrenology makes a hearty comeback this time with the help of AI.

Psychology based on the skull vs psychology based on the face and "micro-expressions"

http://www.victorianweb.org/science/phrenology/intro.html

1.The brain is the organ of the mind.

2. The mind is composed of multiple distinct, innate faculties.

3. Because they are distinct, each faculty must have a separate seat or "organ" in the brain.

4. The size of an organ, other things being equal, is a measure of its power.

5. The shape of the brain is determined by the development of the various organs.

6. As the skull takes its shape from the brain, the surface of the skull can be read as an accurate index of psychological aptitudes and tendencies.

How to Challenge Android’s Monopoly? Is It Even Possible?
I think you are looking at the later stage of IE's life when it was already dominant.

When IE first caught on it was extremely fast and pleasant to use compared to Netscape (also netscape wasn't originally free). If you only cared about IE it was actually a complete breeze to develop for using proprietary stuff like ActiveX (ignoring the fact that ActiveX was a bad idea for various reasons).

Lots of websites started showing banners saying that they were optimized IE, because people were primary targeting IE when they made new websites, in part because it was such a breeze to develop for. IE had lots of HTML/javascript features that made things much easier than other browsers at the time.

It's important to realize that IE only became difficult to deal with once 1) Microsoft essentially stopped trying to improve it after they won all the market share and 2) people needed to make web pages that worked on other browsers. At this point people wanted to use newer features that IE didn't support, but needing to support IE 6 necessitated either abandoning more modern features or using all sorts of hacks/polyfills to work around IE's quirks.
> What ideas do you have on how one can accelerate scientific research?

I work in genetics (as a software engineer).

If there was a major flaw in current scientific research (that involves software), it's that most labs care more about getting published than they do about the reproduce-ability and validation of their work. This means most of the software written in research is ad-hoc, write once, and often never looked at again. It was put together for the sole-purpose of producing some output that could be put in a paper and then lost to time.

A current "holy grail" of software in research would be to fix that: empower other labs to validate and reuse the software written and reproduce the work of other labs with different data sets. And it is actively being worked on in a couple places (that I know of, perhaps more):

* https://genepattern-notebook.org/

* https://app.terra.bio/

* https://software.broadinstitute.org/wdl/

Some of these are just about giving the community a common framework to use for their software (CWL, WDL, Jupyter), others are about data storage and making it easily accessible for others to use in the cloud for reproducing results.

If you want to have a impact, joining one of these groups would probably put you in a much closer position to doing that.

If you just wanted to work on something in your spare time that would be incredibly valuable, then might I suggest this:

It's amazing how much work is done in the scientific community using CSV/TSV files (usually gzipped). And most of that work is done via perl, sed, and awk. And often these are huge I'm working with a VCF file (TSV) right now that's 2 TB in size ZIPPED! It's crazy. Researchers often don't have the time, resources, or know-how to put together a simple Spark cluster and use it.

A command line tool that allowed someone to run SQL (or SQL-like) commands on a gzipped CSV file FAST would be invaluable. And if it could JOIN across CSV files ... wow!
