trendia··on Tildes – A non-profit community site driven by its users' interests
I'm talking about whatever shows up when I go to reddit.com without an account (which is all of the time)
trendia··on Tildes – A non-profit community site driven by its users' interests
> albeit often a wretched hive of scum and villainy depending on subreddit…

I'm more concerned about the opposite effect -- that the default subreddits have become pointless and boring, focusing mostly on "funny" images and cat gifs. Gone are the interesting askreddit threads or useful world news commentary, replaced with content designed to keep you browsing and staying on the site longer.

At the same time, I think the useful content often falls victim to Gell-Mann amnesia, giving votes to anyone who sounds like an expert. It's hard to identify when someone is really an expert or whether they're merely writing like one... The worst I saw was an explanation of laminar and turbulent flow that was 100% wrong, but highly upvoted until a few hours later people pointed out why it was wrong

trendia··on How to Grow Stronger Without Lifting Weights (2014)
With the recent replication crisis in psychology, I would want to see this repeated to see whether it holds up to scrutiny.

It just seems "too good to be true", and with a sample size of 29, it could be.

trendia··on US cell carriers are selling access to real-time phone location data
I wonder if they use this data to price insurance -- they would easily know when their drivers are going over the speed limit (or, if such data is not so precise, if their average speed over 10 minutes exceeded the speed limit).

* Who makes a fan site and puts at the top "#WatchTheExpanse | WATCH LIVE ON SYFY WEDNESDAYS 9/8c"

* Who orders a plane to fly the text # Save the Expanse ? That's at least $400 / hr

* Who creates a "fan" site and posts links to the facebook pages and twitter pages?

Maybe it's a fan, but it looks more like a studio marketing team.

This looks like astroturfing.
trendia··on Australian regulator investigates Google data harvesting from Android phones
It's in Google play services, which is "separate" from Android, but good luck installing your favorite Android apps without it.
trendia··on GDPR will pop the adtech bubble
How is this related to GDPR or the adtech bubble?
trendia··on Ryan Holiday on Conspiracy, Gawker, and the Hulk Hogan Trial
One could also say that if someone puts a video of you having sex without consent, then companies like Gawker will ignore you unless you're a billionaire.

They published a video of a young lady having sex in a bar bathroom, and despite both the lady and her father pleading with Nick Denton to remove the video, he only said "These things pass". The family could not sure, and the outcome was unsure, and Gawker has insurance against these things, so Gawker felt they could get away with it as long as they got the pageviews.

Should you need to be a billionaire to have a non-newsworthy video of you removed?

trendia··on YouTube rolls out new tools to help you stop watching
Is there any way to create a playlist of videos and then resume playback at the same point?

For instance, I have about 20 C++ videos I'd like to watch, and each is an hour long. I rarely have a whole hour, but maybe 20 minutes. I have yet to figure out how to resume playback where I left off, which would be a very useful feature!

trendia··on Amazon’s Fake Review Economy
I'm not even sure that Amazon really benefits from this.

I have become super wary to buy things from Amazon even with good reviews, because I am suspicious the reviews are fake.

trendia··on Google News to be revamped, incorporate YouTube videos and magazines
Luckily, their CEO has learned the power of public relations trick to use so many words to say so little:

> There is always that change aversion. We believe everybody has a home on Reddit. The challenge is finding that home, particularly for new users. Helping them find their home, helping find their community and sense of belonging on Reddit, it’s something we’re not very good at. The redesign is a big effort towards making that better.

trendia··on YouTube Stars Being Paid to Sell Academic Cheating
Sure, they might be found out when they fail their oral quals, but it would be much easier for everyone if there were a much faster way to find them out, such as a low grade from a school that strictly enforces anti-cheating policies.
trendia··on YouTube Stars Being Paid to Sell Academic Cheating
I disagree. Homework and exams have two purposes:

1. Help the student learn (by applying theory in homework and encouraging internalization for exams), and

2. Verifying that students have learned the material

Cheating destroys both of those. A student can copy a solution to a general relativity problem, but that doesn't mean they understand it, and likewise they can obtain the exam before they take it and memorize the solutions, but then the exam only measures whether they've memorized the solution.

That is, cheating completely eliminates the purpose of obtaining an education.

trendia··on Why programmers are not paid in proportion to their productivity (2009)
Google does this to a degree. They sometimes give the same project/goal to multiple groups and pick the winning one.

Unfortunately, in the long run this decreases morale because you don't know if the project you are working on will ever be used

trendia··on Amazon patents method for tracking Bitcoin transactions and selling data to govt
Maybe the examiner didn't feel like fighting Amazon during the prosecution process so they decided to let some future courts handle it.
trendia··on What Data Does Facebook Collect When I’m Not Using Facebook, and Why?
Once the data has been given to a third party, we can no longer be guaranteed that the third party will delete it. That was one of the main problems with Cambridge Analytica -- they claimed to have deleted data but may not have actually done so.

Have you tried "Algorithmic Sleep Solution" [0]? This type of intentional sleep restriction worked for me.

trendia··on China’s Social Credit: Rewards and Punishments
According to the linked article, social credit can be moved up or down for many reasons: "examples infractions include bad driving, smoking in non-smoking zones, buying too many video games and posting fake news online."

That means that if your social credit goes down for any of these reasons, which are not all financial, then you can be barred from the best schools.

I think it's far more likely to be used to keep top schools (which feed into top gov't/industrial positions) clean of any rabble-rousers.

trendia··on Asian-Americans Suing Harvard Say Admissions Files Show Discrimination
The term "diversity" is being used in very different ways. The article you posted drfines it based on skill and knowledge:

> By diversity, we mean differences in how agents build problem representations which allow them to access various solutions. We deploy the concept of diversity along two dimensions: knowledge amplitude, which accounts for the level of available knowledge allowing access to poorer or richer problem representations (compared with complete problem representations), and knowledge variety, which pertains to the differences in the constituents of agents’ representations.

So it just further demonstrates the logical gap between A=B and C=D, since the studies didn't even show A=B, they showed E=F

trendia··on Construction of the Transreal Numbers and Algebraic Transfields [pdf]
So, essentially the transreal numbers treat NaN as a "value"?

"The main difference between transreal arithmetic and IEEE floating-point arithmetic is thus that nullity compares equal to nullity, whereas NaN does not compare equal to NaN."

trendia··on Aarch64 support added
A few benefits:

1. For DSP / image processing, 64-bit SIMD allows you to operate on twice as many elements as 32-bit SIMD

2. For normal computing, you get 31 64-bit registers instead of 15 32-bit registers (essentially 4x register memory)

3. 128-bit floating point

Two different cars with the same mpg can have wildly different emissions. A fuel tax wouldn't discourage higher emissions, only lower mpg!

Done.

trendia··on The Effective Tech Lead Is a 100x Engineer
I can think of an example, though even this is somewhat of astretch:

Suppose person A takes 40 hours to write C code to manipulate a large data set.

Person B puts the data in a database and is able to write commands, which only take 10 minutes, to achieve roughly the same thing.
