Using an iPhone X only proves to me that Apple engineers make incredible software that just work....when they want to. The app switching on iPhone X is perfect bc there was probably a team on that. The problem isn’t new stuff it’s old stuff. Like is there a team just working on Disk Utility or maybe just one dude who checks iOS and macOS for date/time problems. They need a few more people.
Right I think that explains why so many hardware devices have been delayed until they were ready. Yea definitely couldn’t be Craig or other software mangers.
Well go talk to so called leftists and you’ll see we really want to work on infrastructure. While I’m at it I might ask that you reevaluate your opinion on fellow Americans who have different views than you. The ones you see in the news and on twitter are not all of us.
Yea physicists are in a weird spot when it comes to inertia. Everyone’s heard of it but it’s not real. To say something has mass is to say it requires a force to move it which is what we call inertia. And also the E=m equivalence isn’t as simple as may be believed. The famous equivalence is cutting out a piece that is important when talking about photons.
Someone already provided a better answer than I can but just as another example. Constants can sometimes be a tricky name because in programming we think of constants as having a set value, but that’s not entirely what physicists mean. They mean values that have no units. Pure numbers as it were. Sure these may change or we may measure them better but by redefining our units in terms of these constants we kinda sidestep that. There isn’t anything to measure if that makes sense. The only thing to measure is what a meter is.
I do really love how C++ is evolving. The language is fighting and adapting and I think in a very smart way. This old dog can learn new tricks. I also love how often it makes me feel stupid at the incredible knowledge of it's maintainers and implementers.
Maybe there were not any big things in C++17 but I do think they added smaller features that have a big impact. In ways such as we can begin to replace our parameters (where appropriate) with `std::string_view` and things of that nature. Moreover there are many libraries and packages that could see a lot of benefit from a sort of "C++17" refactor.
I think what he's saying is that using `std::vector` is better than using pointers and `malloc` from the point of view of doing simple things. (Simple is not the right term but can't think of a better word). I mean 80% of times.
Yea I was thinking about this too! We can talk all day about static typing vs productivity but if they had a basic string type called PasswordHint and Password then maybe (maybe!) this wouldn’t happen.
I can’t believe I’m actually arguing this but devils advocate I guess: in this instance if they both used the same library then the command line would also have this problem. In this case at least there was a work around in that you could use the cli.
If they thought of doing that they could and probably should be sued. CEOs have a fiduciary duty meaning they are legally implored to do what is best for the company and bringing money back at a 40% tax is not in the financial interest of the company.
I actually never really thought this was that big of an issue but your link is really interesting and brings up some great points. Hamiltonians I think solve the largest issues but I know from talking to people who learn mechanics that that becomes confusing to because dq/dt they think should be related to momentum simply by p=m*dq/dt but it's a tad more complicated than that because you're talking really about a manifold and fancy geometry talk not commonly know to physicists
The big piece of LIGO was the incredible effort that went into data analysis and verification. The second these things were detected a monumental effort went into confirming it meaning when it happened again the methods were already in place. This heavily contributed to how quickly these results were accepted.
Yes this is so important. These are professors and from all the physicists I have ever met they are all incredible open to questions. Remember that these people sit there and think about these problems all day so they love talking about them. Just be polite and especially verbose.
As a physicist who’s listened to him talk about the experiment, it really really makes you take a step back and marvel at how incredible that detector was. And 40 years ago even. He could imagine it but to build it to such an accuracy is incredible and I’m so happy they won it. The teams at LIGO also deserve so so much credit. They work tirelessly!
I thought Tim and the whole team did a great job presenting. And the whole company on every team did a fantastic job making every single piece easy to use. The iPhone X seems like a step forward in phones. I’ve used a number of androids and can say that the usability just isn’t there.
Can’t speak of touchbar but I don’t understand the hate for 3D Touch. I love it and use it a lot. Sure discoverability sucks but I think it’s worth while.
Mostly but also because we haven’t “heard” the waves caused by a Neutron star interaction before. So experimentally we still have to confirm that they cause GWs.
Yea so the universe says nothing can move faster than a massless particle in a vacuum. The photon is the most famous—hence the speed of light—but any massless this can move at it. So GWs do theoretically move at the speed of light, though checking to see if they do requires a lot of analysis and is tricky to figure out. But yes theoretically they do move at the speed of causality (or the speed that things happen in the universe unless someone slows them down)
I’m a physicist who’s now listened to a ton of LIGO’s founders talk about it.
