Coincoin··on Lessons from a 45-year Study of Super-Smart Children
> Is a path of learning more and more about less and less

...until you know absolutely everything about absolutely nothing.

Coincoin··on iPhone 7
I had a 20$ water resistant portable tape player in the 90s with many more holes, buttons and mechanical parts than the iPhone and I could dunk it in water no trouble.

Edit: More like in the 80s.

Coincoin··on How Quaternions encode rotations: derivation and sample code
I would agree if it said "most" instead of "any". Euler angles are useful. Just be very careful with them. Convert to quaternion as soon as possible and convert back to euler as late as possible when needed.

However, you will never entirely avoid them because they are just too practical. Under careful constraints, they make code interfaces simpler.

This is especially important if you are to expose that code to a multidisciplinary team. There is no way you're going to teach an artist how quaternions work just so they can rotate their stuff around the up axis, when simple yaw-pitch angles cover 99% of their use cases.

Coincoin··on A SpaceX Falcon 9 rocket has exploded at Cape Canaveral
Don't worry, unlike the space shuttle, rockets have escape mechanisms. In that specific case, the astronauts would probably have survived as the emergency rocket thingies would have fired and evacuated them far from the explosion before it could reach the capsule.
Coincoin··on Everyday ‘Placebo Buttons’ Create Semblance of Control
This is so common I don't understand how the article didn't even mention it.
Coincoin··on Acetaminophen use in pregnancy linked to child's behavioral problems
Apparently it works better for fever type pain than ibuprofen.

When in real pain, I combine half a regular acetaminophen dose with the regular ibuprofen. Works miracle since the two have different acting mechanisms and they are safe taken together or so I've been told by my doctor. Oh, and a little caffeine will further boost the effect for some reason.

But yes, acetaminophen ridden medication is dangerous, especially with flu and cold stuff since we can be in quite a confused state when sick. I always select a product without acetaminophen when possible.

Coincoin··on Super-hard metal 'four times tougher than titanium'
Now 30% stronger. Same material as used in aeronautic and surgical field. Military grade!
Coincoin··on Pokémon Go Is Teaching Americans the Metric System
In Canada we still use imperial for construction stuff, I guess for import/export reasons.

Oh and Farenheit for water and cooking temperatures. No idea why because I have no freaking idea what a Farenheit is otherwise.

Coincoin··on Zenzizenzizenzic
Yes and no. Yes the system is logical and systematic. However, there are tons of named groups and then there are groups of groups and they all have different and arbitrary priority rules. It's actually quite a clusterfuck for what it does and doesn't really have any real purpose on mildly complex molecules.

Nobody in it's right mind will ever call it by it's real name except maybe to sound more intelligent. Most important molecule have short names either based on the standard or given names.

Coincoin··on A one-dimensional transistor
They will just market it as 3D anyway, and why not add a HD too. If a toothpaste company can do it, they can.
Coincoin··on Can Netflix Survive in the New World It Created?
Yes, that is a common way of firing people under permanent contracts in Europe. You give them a crappy position for a few months until they get bored to death and then offer them to leave for X months/years of salary.
Coincoin··on Electric cars are no longer held back by crappy, expensive batteries
Like any 1.0 product. The technology evolves so rapidly it loses 90% of its value in a few years.

It reminds me my first digital camera, 2000$ and 3 years later you could get better for 500$.

Coincoin··on Automation Should Be Like Iron Man, Not Ultron
I strongly agree that naming variable is an effort worth the benefits, but naming stuff correctly is not 0 extra work. As a matter of fact, judging by how many people give crap names to their stuff, I'd it's one of the most difficult task of designing something.

Finding a name that is both descriptive enough and not overly specific, that describes the 'what', not the 'how', doesn't conflict with other concepts and is not a 20 words Java style keyboard breaker, requires quite a lot of effort.

Coincoin··on LinkedIn password leak
I changed it when they first announced the leak in 2012. It didn't ask me to change it when I logged today and they didn't send me the email today. I guess they know my new password is secure since I changed it since the leak.
Coincoin··on LinkedIn password leak
You don't necessarily need to get your hands on the actual database. You can also obtain the data through a side channel such as debug pages or errors messages being a little bit too generous with information.
Coincoin··on If Philosophy Won’t Diversify, Let’s Call It What It Really Is
The author clearly thinks philosophy is some kind of school of esoterism and after life.
Coincoin··on Medical Equipment Crashes During Heart Procedure Because of Antivirus Scan
Medical devices are used by humans. Humans, for some reason prefer and know Windows better. Why shouldn't the devices use Windows?

Today, doctors from a hospital the other side of the country can diagnose your cancer realtime while you are still in the MRI machine, and they do it with Windows, because that's what humans know and use.

Coincoin··on SpaceX lands rocket at sea second time after satellite launch
Also, the engines are gimbaled. This is essential for the landing burn.
Coincoin··on 'Boaty McBoatface' polar ship named after David Attenborough
They tried doing the same thing here with a replacement bridge. They didn't like the old name for historical/political reasons and tried to change it to a national hero name to make this clusterfuck of a project more inticing. The backlash was infinite and they backed down. Oh and they didn't get reelected for other various reasons.
Coincoin··on Students at Fake University Say They Were Collateral Damage in Sting Operation
However, the university always had a reason to postpone the courses, just like scammers.

In that story, the university was the scammer, always asking for a few more days to "get their money back" and giving them a good faith gift as soon as students started asking questions.

Then, the government punished them for biting to the government run scam.

Coincoin··on Apple Stole My Music
The problem with Spotify is 25% of their library has that horrible UMG watermark on it. It makes any UMG music before 2013 unlistenable. Apparently, UMG fixed the problem on their side but Spotify don't give enough of a damn about quality to redownload the UMG library.
Coincoin··on Weasel Apparently Shuts Down World's Most Powerful Particle Collider
A squirrel made its nest in my shed once. Believe me when I say, everything seems appetizing to them. Just like a baby, except a squirrel will destroy it instead of drooling on it.
Coincoin··on Can a single car break a traffic jam?
Over here, I noticed it is much more pleasant to be stuck in rush hour traffic than off peak. At peak hour, people know the game and know they won't get anywhere faster by cutting and trying to fight for every inch. They tend to stay in their lane, merge smoothly and all lanes go the same speed.

But as soon as the traffic lightens a bit, idiots just come back to break the peace. I include myself in those.

Coincoin··on Science fairs are as flawed as my solar-powered hot dog cooker
I remember in some biology class lab, we were not allowed to get our petri dish out the incubator by ourselves. The lab technician had to verify them before handling them to us. She had to dispose of one because it had a dangerous colony on it.
Coincoin··on Boaty McBoatface and the False Promise of Democracy
Even better, call the boat Sir Boaty McBoatface. Everyone takes a Sir seriously.
Coincoin··on Show HN: Open source colorizing grayscale images with NN
I'm pretty sure if you asked a group of humans to colorize the lighthouse you would probably get the same result.

There is no way, from the greyscale, to know that the sky should be orange.

Coincoin··on For Female Astronomers, Sexual Harassment Is a Constant Nightmare
It's a nice way to make the reader think 15 when the reality is 8.
Coincoin··on In the Future, We Will Photograph Everything and Look at Nothing
I thought it was pretty funny. I took a great picture of the mass of people fighting each other to photograph the Mona Lisa. The ones with the iPad are the dorkiest.
Coincoin··on Why some animals have venoms that are more lethal than they apparently need
That and the article asks the question 3 times and then immediately digress into yet another repetitive example of why the question is so important.
Coincoin··on Drones Are the New Threat to Airline Safety
Also, I think they predict (probably correctly) that it's only going to become more popular so they might as well regulate it before it's too late
