rrss1122··on Why is light so fast?
I think it does. Whatever our choice of units (provided you use the same choice of units in all calculations), the ratio of mass of the proton to the electron will be the same. This is what makes the constant fundamental: it is independent of any way we choose to measure it, so should be the same to anybody and everybody. If we were to meet an alien civilization and study their physics, as long as we know their number system, we would immediately recognize the number 1836.2.
rrss1122··on Why is light so fast?
I think this article does a decent job of trying to describe the first principles we hope we can use to find why the speed of light in vacuum is what it is, but the reality is we still don't know. Plus, the article format doesn't allow for detailed explanation that a book would.
rrss1122··on The Tablet and the Calculator
The price of the calculator is understandable, given the audience it is targeting. What is mind-boggling for me is that Texas Instruments can still get away with selling a TI-84 for $100 new, no doubt with The College Board's help. They are artificially keeping prices high for students by authorizing only a short list of calculators for exams. They don't even allow non-graphing scientific calculators to be used on the AP Calculus BC exam, you must use an expensive graphing calculator.

rrss1122··on Global number of trees is order of magnitude higher than the previous estimate
Could also mean we could need to plant less trees than we thought.

At the very least, the models have to be updated to use a number of trees an order of magnitude higher than we previously thought.

rrss1122··on Why the maker of a chart-topping ad blocker just pulled it off the App Store
If Marco doesn't provide an ad blocker app, someone else is going to do it. If he thinks he's gonna make a statement doing this, that statement is going to fall on deaf ears. Users keep indicating that they want ad blockers, even after hearing the same tired story that it will hurt content creators.

Pretty soon, you won't be able to rely on the ad networks for revenue. Then it's a matter of adapt or die. I think newspapers are better positioned to adapt than traditional web content, because newspapers have the experience of having sales people dedicated to selling ad space on the paper. Pivot those people to selling ads on the website, and roll your own ads, using your own designers and developers (who should make it easy for the sales people to rotate ads using a CMS).

The fight to save ad networks is a race against time that cannot be won.

rrss1122··on My Amazon Burnout Experience
At large companies like this there will always be politics you need to play to get ahead. It sucks but that's the way it is. The meritocratic ideal will remain an ideal unless you're in there on the ground floor.

There's a lot of books out there on corporate and office politics. Might be a good idea to read at least one.

rrss1122··on My Amazon Burnout Experience
The impression I got was, he tried to be manager before being promoted. This gave his managers a convenient scapegoat when he axed his coworkers projects and they needed someone to be angry at. This reminds me a little of The Gervais Principle. This person is a de facto clueless manager (by The Gervais Principle's terminology) who takes the fall for upper management's decisions, and his managers didn't even need to promote him.

What I read was someone who was frustrated with their position in Amazon. Someone who made a bad bargain, not someone who necessarily would not be a great person to work with.

What I found most curious was the need to anonymize. I imagine for upper management at Amazon, finding employees

rrss1122··on Scroll down to see how time flies
I scrolled and scrolled, saw a presentation on the perception of time, then looked at the clock. Time did indeed fly!
rrss1122··on My husband needed therapy after working for Amazon
I think it would be good if the FC workers unionize. It would greatly increase the speed of development for automation solutions and benefit robotics as a whole.
rrss1122··on Ultimate Frisbee’s Surprising Arrival as a Likely Olympic Sport
I don't know, I mean it's fun to watch, but as a spectator sport to fill an olympic stadium? I doubt it.
rrss1122··on Our Brave New World of 4K Displays
I was wondering when I would be rich enough to be able to afford such a set-up. Turns out, it's when I write a tech blog popular enough to make affiliate links worthwhile.
rrss1122··on July was Earth’s hottest month in what’s destined to be Earth’s hottest year
It specifies it in the article, but if you went just by the title, it is not the Earth's hottest month in Earth's hottest year. It is the hottest recorded month, but not Earth's hottest month.

When we start seeing megafauna in Antarctica like we did when dinosaurs lived there, or even any land animals besides penguins and humans, then we can start talking about Earth's hottest months.

rrss1122··on The Neuroscience of Drumming
Neil Peart and Geddy Lee, now THAT is a great rhythm section.
rrss1122··on The Neuroscience of Drumming
I share that curiosity. A band works best when the drummer and the bassist are "locked in". I have to imagine that if a neuroscientist were to image the brains of both the drummer and the bassist in a band with a really good rhythm section, their brains would "look" very similar.
rrss1122··on Jeff Bezos Says Amazon Won’t Tolerate ‘Callous’ Management Practices
From all that's come out over the weekend, it sounds like former Amazon employees are quite welcome over at Facebook. Plus, like Bezos says in his all-hands e-mail, these people are recruited every day. If they are in a situation like that, escalating to HR won't make it better, changing jobs will.
rrss1122··on Let’s sunset C/C++
Any secure remote access software is the most secure, except when it isn't. This is a tautology, doesn't reveal any deep insight.
rrss1122··on Let’s sunset C/C++
"I don’t see many people in the security industry taking up this call..."

http://www.viva64.com/en/b/0324/ [Criticizing the Rust Language, and Why C/C++ Will Never Die ]

"It is crystal clear for every sane programmer that C/C++ is not going to die in the nearest future. No one is going to rewrite almost all of the existing desktop applications, operating system kernels, compilers, game and browser engines, virtual machines, databases, archivers, audio and video codecs, tons of other C-libraries, and so on and so forth, into other languages. This is a huge mass of fast, debugged, and time-proven code. Rewriting it is way, way too expensive, risky, and, honestly, doesn't seem to make sense except in the heads of the most frantic Rust fans. The demand for C/C++ programmers has always been high and will remain so for a long time to come."

Seems like just more proselytizing from Rust fans looking to expand their ranks. Of course more people in the security industry are not taking up this call, because it is a ridiculous suggestion.

rrss1122··on What ‘Game of Thrones’ Does to Your Heart Rate
You can try getting a tighter fit and see if that helps.

I've noticed with any consumer heart rate monitor, if the fit is not tight and the monitor moves even a little bit, the heart rate the monitor reports will be off. I'm assuming the same will apply to the Apple watch.

rrss1122··on What ‘Game of Thrones’ Does to Your Heart Rate
I thought I read somewhere that the heart rate goes up after eating due to the stomach requiring more blood to digest. I also read that foods that cause blood sugar to rise quickly will also cause the heart rate to rise. Does this sound like it makes sense?

Also, would a super burrito contain enough minerals to affect cardiac action potential?

rrss1122··on Every city wants to create its own Silicon Valley. This is bad for innovation
The article doesn't make it seem that it is bad for innovation. If one company can serve regional interests better than another three timezones away, seems like it would be good innovation for me. Besides, once those parking apps start getting bigger inevitably most of the competition will start going under as the bigger, more successful companies out-innovate each other and eventually they'll start merging or getting bought out.

The article is in fact full of good examples of innovation. The title is misleading.

rrss1122··on The pressure to achieve academically is a crime against learning
You accuse debacle of being presumptuous, but you are presuming debacle doesn't already teach his/her son how to deal with people, learn he lives in a society, that sometimes life is boring, and that sometimes you are not the only one.

By the way, school is not the only answer for any of the questions you asked.

rrss1122··on The pressure to achieve academically is a crime against learning
Talk about zealot...
rrss1122··on G is for Google
I see. I wasn't entirely clear on it, and I guess the source I got it from wasn't either.
rrss1122··on G is for Google
You would be way late on that. Even he dropped Snoop Lion.
rrss1122··on G is for Google
One thing I've heard is that this would help them in terms of taxes, allowing them to write off projects that don't make money, although I'm not entirely clear on how Alphabet would accomplish this.

That would be no joke if that was a reason to do it.

rrss1122··on You Will See the Doctor’s Fallibility Now
I had similar problem as a kid, just couldn't remember the words for left and right until someone finally told me "L for left hand".
rrss1122··on You Will See the Doctor’s Fallibility Now
That is so frustrating. And it's not just you talking out of your ass, you had your vaccine records there for them to see and they refused.
rrss1122··on War in Space May Be Closer Than Ever
A space race to Mars is a fun, if monstrously wasteful economically, way for the nations to one-up each other.

A space race to build weapons to destroy each other's satellites is not fun, and not good news. I don't see the higher probability of armed conflict with Russia or China as a good trade-off for development of space technologies. And going to war because "we damn well deserve it" is a terrible reason.

rrss1122··on Opera Software Board of Directors to Review Strategic Alternatives
Opera used to be one of my favorite browsers. Then they went webkit/blink and threw out every feature that made Opera, Opera, essentially turning it into an even more stripped down version of Chrome (new Opera didn't even have bookmarks at launch).

Now they see their experiment didn't work and are looking to cash out before it's too late.

rrss1122··on Will Doctors Soon Be Prescribing Video Games for Mental Health?
In my experience, the only long-lasting change video games produce in the mind is the craving to play more video games. They are certainly addictive, but it's doubtful that they help mental health. Sure, people can use them to escape from the world and as a distraction from real mental health issues, but (again in my experience) that distraction works only while playing the video game and for a very short time afterwards.
