QUESTION
I'm trying to remove an entry from the Caffeine cache manually. I have two attempts but I suspect that there are some problems with both of them:
This one seems like it could suffer from a race condition.
...ANSWER
Answered 2021-Jun-16 at 00:25You should use cache.asMap().remove(key) as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.
The Cache interface is opinionated for how one should commonly use a cache, while the asMap() view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.

QUESTION
How do I produce an animation that simulates the burning effect of fire consuming an UIView from top to bottom in Swift?
I found Fireworks, an app that allows users to tweak and try out different settings of CAEmitterLayer with instant results. The effects are great for applying to a whole screen but how would I use it for my purpose - where the UIView must disappear as the fire consumes it from one end to the other?
Is there some tutorial on consuming UIViews with fire using the particle emitter anywhere? I know that I’m supposed to show some code but anything I put here would be irrelevant. I’ve also exhausted my search engine looking for something similar. That’s how I found the Fireworks app actually.
This seems to be a use case that shouldn't be uncommon.
...ANSWER
Answered 2021-Jun-14 at 14:24I was once in your shoe before and came across this Open source library called particle animations.
I would NOT recommend using the library itself since it's deprecated. But I would recommend referring to its source code to get an idea of how to use CAEmitterLayer and CAEmitterCell to make the looks of a Fire!
As you could see from its readme, it has direct examples of Fire. It also states that even Apple and Facebook uses CAEmitterLayer and CAEmitterCell to produce the effect of a fire.
Feel free to ask for more questions.

Answered 2021-Jun-14 at 20:19We could calculate the interactions by hand; done easily by first creating the terms trms, then evaluating them in an eval(parse()) approach.
QUESTION
I am working on a Instagram face filter/effect with SparkAR. It is successfully uploaded, approved and works just fine when across many devices when I try the effect in the Instagram app. I can select the effect when creating a Story however – I cannot when doing a Live stream. The effect symbol doesn’t show up nor can I select it when searching for the effect, while all the other effects are still there.
One user reported that she was able to select the effect during Live on her Android device. But at least on iOS devices it seems to be impossible to find or select the effect.
Are there any differences between Live and Non-Live effects? Or between iOS and Android effects? Has anyone had the same problem before? How can I make sure that my effect is available for Live streaming?
Thank you for any hints!
...ANSWER
Answered 2021-Jun-15 at 08:37Turns out, that the use of audio inside the filter caused it to not appear in Live mode. I removed all audio files and playback controllers and enabled the microphone. It now works.

...ANSWER
Answered 2021-Jun-14 at 11:40The statements given are valid under Fortran 2003 and later, but not in Fortran 90/95.
You really want to be using a compiler which supports Fortran 2003 (and indeed much later versions) and the comments suggests ways to look for this. There is no guarantee that this is the only Fortran 2003+ parts of the code you want to compile. However, there's a history lesson available here which tells us about a workaround.
First, the obvious workaround is
QUESTION
Hello all!
I recently learned that in newer versions of SQL Server, the query optimizer can "expand" a SQL view and utilize inline performance benefits. This could have some drastic effects going forward on what kinds of database objects I create and why and when I create them, depending upon when this enhanced performance is achieved and when it is not.
For instance, I would not bother creating a parameterized inline table-valued function with a start date parameter and an end date parameter for an extremely large transaction table (where performance matters greatly) when I can just make a view and slap a WHERE statement at the bottom of the calling query, something like
ANSWER
Answered 2021-Jun-14 at 22:08You will not find this information in the documentation, because it is not a single feature per se, it is simply the compiler/optimizer working its way through the query in various phases, using a number of different techniques to get the best execution plan. Sometimes it can safely push through predicates, sometimes it can't.
Note that "expanding the view" is the wrong term here. The view is always expanded into its definition (NOEXPAND excepted). What you are referring to is called predicate pushdown.
I've assumed here that indexed views and
NOEXPANDare not being used.
When you execute a query, the compiler starts by parsing and lexing the query into a basic execution plan. This is a very rough, unoptimized version which pretty much mirrors the query as written.
When there is a view in the query, the compiler will retrieve the view's pre-parsed execution tree and shoves it into the execution plan, again it is a very rough draft.
With derived tables, CTEs, correlated and non-correlated subqueries, as well as inline TVFs, the same thing happens, except that parsing is needed also.
After this point, you can assume that a view may as well have been written as a CTE, it makes no difference.
Can the optimizer push through the view?The compiler has a number of tricks up its sleeve, and predicate pushdown is one of them, as is simplifying views.
The ability of the compiler here is mainly dependent on whether it can deduce that a simplification is permitted, not that it is possible.
For example, this query

QUESTION
I am trying the equatiomatic package to plot my lmer model.
...ANSWER
Answered 2021-Jun-14 at 20:36I'm the developer of that package. It should work with lme4::lmer() equations. The issue here is with dropping the intercept but having it vary randomly at higher levels. See this issue for more details.
If you have suggestions for how you would expect the equation to render, I'm open to working out a fix. But for now, equatiomatic::extract_eq() assumes that whatever random effects you have also have corresponding fixed effects.
