Can Rust save the planet? Why, and why not

Draco

There are at least three reasons C vs C++ performance might differ

C and C++ are not the same language and there are a few corner cases were C code won't compile the same in C++, but ... I am digressing.

1) The programming paradigm is different between C and C++. In C++, you are "encouraged" to use C++ features - like the STL (Standard Template Library) instead of managing your data structures with malloc(), realloc(), and free(), or streams instead of printf() and FILE. So, equivalent C and C++ programs will look different.

2) C and C++ runtimes are different. C has no need for exception handling.

3) Even if you compiled a C program as a C++ program, things like structs get default constructors and destructors in C++.

Great! Another way to bloat and slow the browser.

Don't get me wrong, web browsers are pretty amazing - not to mention, extremely complex. What was once a thin client for remotely viewing and navigating documents has become a rather fat thin-client.

In fact. each passing iteration seems to be inching the browser closer and closer to being a full OS running as a guest on some target hardware (something Google anticipated back in 2009 with the release of ChromeOS).

AI-enhanced frog stem cells start to replicate in entirely new ways

Draco

To paraphrase Arthur Dent:

Ah, this is obviously some strange usage of the word 'replicate' that I wasn't previously aware of.

To be fair, the paper is talking about robotic assembly of other self-similar robots. The fact that these robots are assembled from cellular matter is irrelevant to the discussion - except that ... it's really cool (or creepy) to talk about previously living cells being shredded, assembled into a sort of Frankenstein monster, and then, themselves, assembling other Frankenstein monsters from similarly shredded cellular material.

For those who didn't read the paper, the steps are as follows:

1) Take a frog stem cell and remove the contents

2) Take the cell husk and strip off the outer layer

3) Assemble the cell inner layers into a "robot"

4) Put robots in an environment filled with the inner linings of cell and watch the robots "assemble" copies of themselves.

I see this less of a great leap in self-assembling robotics (although the shape is interesting) and more a testament to the tenacity of life to go on even after it's been horribly mutilated. This type of experiment shows that the forces binding life isn't just about the DNA, RNA, or macro-scale organisation - it is far deeper.

Thousands of Firefox users accidentally commit login cookies on GitHub

Enough with the demands for Totalitarian control.

>> "I'm frustrated that GitHub isn't taking its users' security and privacy seriously," Marlin told The Register in an email.

GitHub isn't a mind reader. It doesn't know which uploaded data is private and which isn't. It trusts that the user correctly commits files to public and private repositories.

Every single file that is uploaded - publicly visible or not - is a potential security threat, data leak, or doxxing.

I can think of at least two legitimate reasons for uploading and making public facing a cookies.sqlite file:

1) controlled data to work with

2) a honeypot

Yes, some idiots might "accidentally" upload that file, but they might also "accidentally" upload their banking details as well or any other file that contains "sensitive" information.

Google lab proposes solar-powered moisture farming to provide water for billions

Draco
Windows

It takes energy to extract water from the air

Why kWh instead of Joules?

The atmosphere is a HUGE energy exchange system. Energy is put into water, turning it into water vapour. That water vapour is transported by the atmosphere. Energy is removed from the water vapour and it precipitates or condenses out.

In the places where these systems are being proposed, the atmosphere is not pulling energy out of the water vapour and thus causing it to precipitate. Therefore, the solution is to extract the energy from the water, thus causing it to condense.

It takes a lot of energy to vaporize water. For example, to vaporize 1kg of water requires:

2500000J @ 0C

2453000J @ 20C

2256000J @ 100C

In order to condense the water, you must remove that amount of energy. One way of doing this is with a refrigeration system of some sort which moves heat from a cool plate to a hot plate.

We tend not to use Joules because energy doesn't care about time. We prefer to use a timed measure of energy - such as kWh: 1 kWh = 3600000J of energy over 1 hour.

-------

Why would you get less water from a higher relative humidity?

How much water the atmosphere can hold depends on temperature. Consider the following quantities of water in the atmosphere at 100% humidity levels:

4.89 g/m³ @ 0C

17.3 g/m³ @ 20C

30.4 g/m³ @ 30C

At 0C, 90% relative humidity, the maximum amount of water you could extract from a cubic metre of air is 4.89 x 0.90 = 4.40 grams (about 4.4ml).

At 30C, 30% relative humidity, the maximum amount of water you could extract from a cubic metre of air is 30.04 x 0.30 = 9.12 grams (about 9.1ml).

While the paper references to papers it is pulling its number from, it seems the authors are not clear on what they are talking about and don't seem to understand how to present the data in a coherent manner. IMO, it reads like a "publish or perish" filler fluff.

Re: FTFY

As someone who was born and raised (until we left) under Communism, I have no hate for anyone, nor do I see other people as my enemy.

Love of your homeland is strong in people - regardless of the government in power - but love of your homeland is not the same as love of the government.

I find the failure to distinguish between "the people" and "the government" very common among Westerners. I suspect, this occurs because Westerners have the luxury of political tribalism with its attendant hate of other political tribes. Or, in other words, people under Communism (or any Totalitarian system) don't have the luxury of political tribalism and all the "two minute hate" it rallies forth against its opponents.

Most people just want to get on with their lives without hating anyone or having anyone hate you. So you keep your head down and ignore the politics - except, it seems, in the luxurious West.

Twitter's machine learning algorithms amplify tweets from right-wing politicians over those on the left

Draco
Windows

Self-serving study

The explanation of the methodology is quite good, but the discussion in the paper is designed to push the narrative that their algorithm tends to promote conservative / right leaning tweets more than liberal / left tweets.

The raw data is missing, along with data on the political leanings of those engaging with the tweets. From what I gather on the Internet, in the US and UK, the users skew to the left. (In the US, 60% of Twitter users lean Democrat, 35% Republican : https://www.pewresearch.org/internet/2019/04/24/sizing-up-twitter-users/).

As the paper notes: The selection and ranking of Tweets is influenced, in part, by the output of machine learning models which are trained to predict whether the user is likely to engage with the Tweet in various ways (like, reTweet, reply, etc). [SI 1.14]

I think The Economist expressed best when it took a look at Tweet favouring in 2020: The platform’s recommendation engine appears to favour inflammatory tweets https://web.archive.org/web/20200803093134/https://www.economist.com/graphic-detail/2020/08/01/twitters-algorithm-does-not-seem-to-silence-conservatives

Those inflammatory tweets are exactly the ones that are going to get engagement. As the paper notes, the only type of tweets they considered were: We then selected original Tweets authored by the legislators, including any replies and quote Tweets (where they retweet a Tweet while also adding original commentary). We excluded retweets without comment.. [p3. Results]. The rationale for excluding tweets without comment was: attribution is

ambiguous when multiple legislators retweet the same content [ibid]. I think there is an additional problem / bias - (I suspect, but have no data to support this) people will retweet without adding a comment if they agree / support the tweet, but are more likely to attach some editorial comment ("SO STUPID!!!") when they disagree / oppose the tweet. [Ambiguity note: I find the paper ambiguous on whether it is only "legislator" retweets without comment that are ignored, or if that includes any "engaged" retweet of a legislator's tweet / retweet without comment]

Since humans - like all animals - are evolved to watch and attend to (i.e. "engage with") wany real or perceived threat, tweets that are "oppositional" will garner more attention. Since (at least the US and UK) Twitter users are left leaning, they will engage with what they perceive to be threats - which is what the algorithm will serve up to them, which will come from the other side of the political aisle. QED. Or to repeat what The Economist said: The platform’s recommendation engine appears to favour inflammatory tweets

-------

Why the paper is self serving:

In the main body, it argues: With the exception of Germany, we find a statistically significant difference favoring the political right wing. This effect is strongest in Canada (Liberals 43% vs Conservatives 167%) and the United Kingdom (Labour 112% vs Conservatives 176%).

Yet, when you look (in Canada) at the amplifications of individual legislators, you see the Liberals and Conservatives are (almost) perfectly mirror each other (Chart 1C) - i.e. the amplification of individual members of the Liberal or Conservative parties is pretty much the same, yet the group amplifications are very different. The paper explains that this "discrepancy" is explained in SI 1.E.3 (which, I think is meant to be SI 1.5.3).

It is easy to see that if amplification a(G) of a group G were a linear function of the amplification of individuals i ... [then the sum of] individual amplification parity implies equal group amplification" [SI 1.5.3] (substance of the quote, equations didn't come through)

However, our definition of amplification does not satisfy this requirement. To see why, consider the function f (G) = |UTG|, where TG is the set of Tweets authored by members of the group G and UTG is the set of users who registered an impression event with at least one Tweet in TG. The function f is a submodular set function exhibiting a diminishing return property f (G ∪ H) ≤ f (G) + f (H). Equality would hold if Tweets from groups G and H reach completely non-overlapping audiences. [SU 1.5.3] (Again, apologies for the not quite 100% quoting, but ... equation problems).

This means that you have a much wider range of tweets from the Conservatives than the Liberals (remember, I'm looking at the Canada result / conclusion). Recall, from Graph 1C, individual Liberal and Conservative legislators get about the same amplification, but when we aggregate the amplification by group, the Liberals get less amplification than the Conservatives. But, the aggregate is a submodular set function: if the Liberals are all sharing the same tweet ("Conservatives Evil!") then each individual Liberal will get their individual "amplification", but the aggregate tweet amplification will be for that one tweet and consequently lower because of the high overlap for that tweet; if individual Conservatives are tweeting all over the place ("Liberals Evil!" or "Crystal Skulls" or "We're not the Liberals!"), each Conservative will get their individual "amplification" (which, more or less, matches the individual Liberals), but the aggregate group tweet amplification will be higher because there is less overlap with the tweets. This leads to (at least) two different ways to spin: (1) Liberals are focused and on point, Conservatives are all over the place, (2) Liberals share only one voice, Conservatives have many individual voices.

Now, many countries (apart from the US) have multiple parties. The paper focuses on Comparing the amplification of the largest mainstream left- and right-wing parties in each country [SI Figure S1A] and ignores all the other parties. In Canada, there are 2 other parties listed (NDP and BQ, both are leftist - indeed, the BQ has higher amplification in Canada than the Conservatives). Why aren't the Left and Right aggregated together so we can see the Left / Right amplification? Why is the amplification provided for only individual parties, but then generalized as "the right-wing gets more amplification". The Liberals + NDP + BQ are 3 left voices vs the one Conservative voice in Canada.

We should ask what the binary left / right "amplification" was for other countries (as well) and not just the party amplification (and then present that as representative of the left / right amplification):

UK : 3 left + 1 right

Germany : 3 left + 3 right

France : 3 left + 4 right

Japan : 2 left + 3 right

You can't be that willfully blind to the text. If your reading was even remotely true, then I would have expected the paragraph to look something like this:

The biggest problem with COVID-19 death is it is only "something happened after infection". You could have a bad heart, get infected, then have a heart attack you would have had otherwise and it can be included.

The whole point of recording adverse effects following infection or vaccination is to see if there are any correlations.

Re: Green energy

The first "official" observation of the Great Red Spot was in 1831 by Samuel Heinrich Schwabe.

However, there were earlier reports of spots on Jupiter. Robert Hooke observed on 9 May 1664 "a small spot in the biggest of the 3 obscurer Belts of Jupiter".

This was later, apparently confirmed by Giovanni Cassini: "Besides that Transient Shadow last mentioned, there hath been observed, by Mr. Hook first ... and since by M. Cassini, a permanent Spot in the Disque of Jupiter."

Both are recorded in the Philosophical Transactions of the Royal Society of London 1666. Pages 3 and 143, respectively.

Surely, he meant to say “Webb is an exemplary mission that signifies the epitome of bureaucratic mismanagement, mission creep, and pork-barreling,” said Gregory Robinson, the telescope’s program director at NASA.

Interesting

I'd always wondered if there were other programming languages built on a non-English substrate.

I can certainly see the attraction of writing code using a syntax like:

programa

{

inclua bibliotexa Matematica

funcao inicio()

{

inteiro variavel = 123

}

which would be less intimidating to a native Portuguese speaker, than:

program

{

include library Matematica

function main()

{

integer variavel = 123

}

Of course, one can argue that English is the lingua franca of science and engineering - but, I am sure, it won't always be so.

Of course, the language mapping might be less of an issue for those who "instinctively" view things like int, char, etc as symbolic than linguistic elements.

Anyone know of other programming languages that use another language or glyph system (Cyrillic, Hiragana, etc) at their core?

I'm pretty sure this is a clear example of "historical nihilism" - which, at its essence, is political thoughts with strong political tendencies and intentions that seek to distort the history of modern China's revolution, the CPC and the armed forces under the guise of "reevaluation,"

Seems like fusion power gets reaching the same milestone

>> This is a notably milestone, the scientists said, because it puts them at the threshold of fusion ignition, which is the point where a fusion reaction becomes self-sustaining

I am pretty sure this milestone has been repeatedly reported over the past 40+ years.

It's almost as if fusion research is stuck in a temporal loop and keep emitting the same press releases.

Re: Good work for game devs, if they don't vanish

How can someone who never existed vanish?

As an aside: hallucinating game devs who never existed is a sure sign of mental illness. Fortunately, re-education centers have a long, proven, track-record in treating such cases. They are very patient and think nothing of spending 10, 20, or more years in treating your delusions.

Common practice

Since (at least) the 80s, the following terms have been common in contracts I have been asked to sign: (1) "We own everything you create while you are employed with us - whether on company time or your own time." and (2) "You are prohibited from working in this field for 10 years following termination of employment with this organization."

I have always refused to sign them until they are stricken.

Twitter's AI image-crop algo is biased towards people who look younger, skinnier, and whiter, bounty challenge at DEF CON reveals

Re: Is it the algorithm that's biased?

tfb wrote: So the data he presented to test the algorithm was not skewed by whatever the demographics of Twitter are.

I'll accept the claim that the researcher presented a broad uniform (or reasonably uniform) sample range of facial data to Twitter's algorithm and he observed a non-uniform selection bias.

But Twitter's algorithm is, likely, trained using data from Twitter users - whose demographic is skewed. Therefore, you would expect the algorithm to be skewed in favour of Twitter's predominant demographic. It would take a conscious effort to ensure an "unbiased" training set. But ... by the act of making it "unbiased", you are biasing it against the predominant demographic. Or, to put it in another way, you have to weight higher non-representative users of Twitter than representative users. (And we are not even accounting for general human preference for younger, healthier looking people).

The likely problem is that Twitter's algorithm was trained using the proxies of engagement, likes, and retweets. The correct way to fix this is to actually train an algorithm for face cropping - which means it has to have some notion of what a face is. Unfortunately, no ML or AI has any clue what a face is (or any other object for that matter). See the following articles on how image classification can disrupted).

https://www.theregister.com/2017/12/18/black_box_ai_attack/

Anything you put on a face - glasses, glitter, paint, makeup, hat, mask, etc - can make the face classifier think it's a turtle, or toaster, or banana ... or something ....

Is it the algorithm that's biased?

The claim is that the cropping algorithm is biased because it tends to produce crops of "people that appear slim, young, of light or warm skin color and smooth skin texture, and with stereotypically feminine facial traits"

I make the counter-claim that the cropping algorithm has no clue what it is cropping. I further posit that the cropping algorithm was not trained to recognize slimness, youth, skin tone, skin texture, or feminine facial traits, but rather was trained using more mundane metrics like: how long users paused at the image, how many likes the image had, how many shares the image had - since those are things Twitter can reliably measure.

The bias, if any, is in Twitter's users who are more likely to pause at, like, and share images of young, warm and smooth skinned, feminine faced people - something that is easily treatable with a 10 year stay at a Xinjiang re-education camp.

Alternatively, it could be that the "bias" is more reflective of the demographics or Twitter users and their in-group affinity compounded with evolutionary bias for markers for attractiveness (such as youth, and the general air of being healthy).

Consider that the top 20 countries using Twitter could be claimed to have populations that are predominantly "light or warm skinned": (1) USA, (2) Japan, (3) UK, (4) Saudi Arabia, (5) Brazil, (6) Turkey, (7) India, (8) Indonesia, (9) Russia, (10) Mexico, (11) Spain, (12) France, (13) Canada, (14) Philippines, (15) Thailand, (16) Australia, (17) South Korea, (18) Germany, (19) Argentina, (20) Malaysia.

(Source: https://blog.hootsuite.com/twitter-demographics/)

As well, 62.6% of Twitter users are between 13 and 34 years old. (same source as above).

I also posit, that people are more likely to tweet flattering images of themselves than unflattering ones.

I don't deny there are, probably, people who post a picture of decrepit homeless men, passed out drunk in an alley, but that's not as likely to garner as much engagement as a healthy, young woman, laughing at a party.
