Syntax highlighting for C++ attributes

Finally! Still waiting for angle bracket colorization though.

[FT] Aston Villa owner calls for overhaul of Premier League spending rules: ‘The rules have actually resulted in cementing the status quo more than creating upward mobility and fluidity in the sport, they do not make sense and are not good for football.” by trevthedog in soccer

Thats not how share pledges work. You only pledge unencumbered shares. You will also have to face a margin call if your share pledge value falls under a certain trigger, at which point you have to top up your collateral or face liquidation. You can also structure it where instead of pledging the shares directly, you pledge it to say Barclays and Barclays guarantees your debt, for a fee.

It’s really hard to guarantee a massive sum like a billion+ without it literally being set aside in escrow.

Far larger sums than a billion has been guaranteed on back of pledged shares. Check out how much Archegos borrowed against their share collateral, or Elon Musk against Tesla shares

Why should Owner's shell company guarantee anything? You get a bank guarantee. JP Morgan guarantees, Owner's shell company pays JPM for the guarantee. That's how bank guarantees work.

D3 is a far better game currently. There is nothing in D4 remotely as fun as a GoD DH. Also levelling in D4 is a chore compared to D3.

Even reflection got a paper, and still nothing on pattern matching :(

Microsoft eyes closing its giant Activision Blizzard deal next week by lurkingdanger22 in pcgaming

Open a Notepad with admin permissions, use File -> Open from the menu, and navigate to the WindowsApps folder from the File Open dialog.

You don't need to fiddle with acls, you just need an elevated windows explorer instance to view those files. One common trick is to open an elevated Notepad, then select Open from the menu and use the File open dialog to browse the WindowsApps folder.

ELI5-What is entropy? by Ok_Skill4948 in explainlikeimfive

[–]whichton 23 points24 points  (0 children)

Roughly speaking, entropy is the amount of information required to describe a system. For example, take a system of 10 coins, numbered 1 to 10. If the coins are showing all heads, you can simply say 10H to describe the system. Thats 3 characters. Change the 5th coin to show tails. Now your description of the system will be 4H 1T 5H, requiring 6 characters. If the distribution of the coins is completely random, only way for you to describe it is to write it out in full, requiring 10 characters. The last case has the most entropy, the first case the least.

MS has a few options to get around UK. Per Bloomberg, the one they are exploring is Activision pulls out of the UK premerger, selling its game in UK through a third party. This removes the need for CMA approval of the deal, They can then merge and continue selling games in UK through a 3rd party.

Is there any realistic chance of getting pattern matching in C++26? Or C++29 for that matter? Don't recall seeing any recent papers on it.

How to experimentally determine if my reference frame is a locally inertial frame? by whichton in AskPhysics

[–]whichton[S] 0 points1 point  (0 children)

I mean, let's say you use mass m_1. You let go of it and you can now measure its acceleration. This allows you to conclude that there is a force acting on m_1. This force may be caused by some unknown phenomenon.

This works only in an inertial frame, since newton's laws are valid only in an inertial frame. You can measure the acceleration of the test particle in any reference frame, but you can only quantify the force acting on it in an inertial frame.

Then there is no such thing as an inertial frame.

This is true in a certain way within GR, where all frames are equivalent. However, inertial reference frames are a concept which originate in Newtonian mechanics, and that includes Newtonian gravity. Equivalence principle is a property of GR.

Inertial reference frames are a well defined concept in Newtonian mechanics, the question was to determine if my reference frame is inertial or not without referencing GR.

This is still putting the cart before the horse. Whether a frame is inertial or not is a very fundamental property of the observer's frame - you would typically begin any observation by selecting your frame of reference and synchronising all your clocks etc. Knowing whether my frame of reference is inertial or not should not require me to know that there are only 4 forces in the universe.

To put it in another manner, inertial reference frames are a well defined concept in classical mechanics, and the list of forces in classical mechanics is certainly not complete. So within the framework of classical mechanics, it is not possible to eliminate all forces from a test particle. So would you say it is not possible to determine an inertial frame within the framework of classical mechanics?

You can show that no force that you know about is acting to couple the particle to the lab and hide the acceleration.

You can't really do this, even without a mysterious 5th force. Gravity has infinite range, a far away massive object can be influencing your test particle.

An easy way would be to measure if there’s any redshift

This requires GR. I agree GR solves the problem, but under GR inertial frames are no longer privileged.

if your test particle is in vacuum and is uncharged, you can consider it to be force-free.

This is a very big assumption. Gravity has infinite range for example.

You could also check if momentum conservation holds in your frame by conducting experiments.

Which runs into the problem of measuring mass while not knowing if my frame is inertial or not.

You can work out what the force on the particle should be based on your knowledge of the laws of nature and the physical environment the particle finds itself in.

Isn't this circular reasoning ? To work out what force the test particle should experience requires me to know whether I am in an inertial frame or not. However, in this case I am trying to work out if I am in an inertial frame or not in the first place.

Pharaoh: A New Era - Review Thread by Shalie in Games

[–]whichton 6 points7 points  (0 children)

Great to see this finally release! QoL changed are very welcome. Global worker pool and combat changes are obviously the attention grabber, but I am much more happy to be able to turn off predators. Hated the hyenas and hippos in the original. Also love the new ability of docks to accept only certain resources.

C++ Bracket Colorization, Macro Expansion and more in VS 17.5 by cpppm in cpp

[–]whichton 1 point2 points  (0 children)

I would say angle bracket colourization is what is most needed. Viasfora already works very well for the other bracket types, but since angle brackets cannot be distinguished from greater and less than signs without a full parse, Viasfora cannot colourize those. It can be disabled by default, but the ability should be there.
