There are several advantages to not having them: without all the extra parts needed to support these features you can make the phone thinner (thickness is traditionally a key marketing point for smartphones) and cheaper to make.
Additionally, it seems that a lot of people no longer need these features, making them prime candidates for exclusion: Bluetooth headphones have become very common, internal storages have become large enough, and people buy a new phone often enough nowadays that battery wear is not as much of an issue.
Of course, if you are one of the people who still do want these features you’re pretty much out of luck. Which sucks.
What he means is, if you want to download the document from ISO that describes the standard, you have to pay a fee. Here’s their store page: click.
It’s about 190 USD for a 38 page document describing the rules of the standard. There’s another document with extensions for a similar price. Quite pricey for a PDF file obviously, and the RFC is free to download.
On the other hand, no one in the history of time has gone “hmm, I don’t know how ISO-8601 works, let me go buy this document from the ISO store to figure it out.” Most people just call datetime.isoformat() or whatever their library function is called.
Not really no. Special relativity explains the relationship between space and time. General relativity expands on this to account for gravitation.
One of the postulates (i.e. assumptions) of relativity is that the speed of light in vacuum is the same for all observers. But the theory doesn’t actually require any particular value for c, it only needs it to be constant. And it doesn’t explain the behavior of light in a medium at all.
In fact, relativity doesn’t explain the mechanism by which light interacts at all, that is the domain of Quantum Electro Dynamics.
The Rankine scale is generally measured in degrees. That’s because it’s defined in terms of the Fahrenheit scale, which is also measured in degrees. i.e. 1 Rankine degree = 1 Fahrenheit degree.
This is not the case for the Kelvin scale, which is defined directly in terms of thermal energy: 1 Kelvin ≈ 1.38*10^-23 J. Coincidentally (but not really of course) this amount of thermal energy is such that an increase of 1 Kelvin corresponds to 1 degree Celsius.
This is rather pedantic, as you could easily define Rankine in terms of thermal energy as well. Some people do this and don’t say “degrees” in front of Rankine. Or, you could define the Kelvin in terms of the Celsius, and measure it in degrees.
tl:dr Rankine has degrees, but for mainly historical reasons.
P.S.: Kelvin actually also had degrees until 1968!
Lots of tools ignore xdg, and issues asking to add support get bogged down in backwards compatibility problems. The best they achieve is to introduce yet another env variable to control where the config goes. It’s really annoying.
I have a bunch of TOOLX_CONFIG=“$XDG_CONFIG_HOME/toolx” stuff in my bashrc.
Kinda funny that this person correctly explains the silly hysteria people had over E-numbers and then in the same comment spreads some silly hysteria over aspartame.
