Random row from Linq to Sql
...nough, you don't actually need to get the count. You do, however, need to fetch every element unless you get the count.
What you can do is keep the idea of a "current" value and the current count. When you fetch the next value, take a random number and replace the "current" with "new" with a probab...
if a ngSrc path resolves to a 404, is there a way to fallback to a default?
...or occurs (which will be because the image doesn't exist or is unreachable etc) we capture and react. You can attempt to get the image sizes too - if they were present on the image/style in the first place. If not, then set yourself a default.

Why can tuples contain mutable items?
...ore memory efficient to create because there's no need for overallocation, etc. They're a bit slower than lists for random item access, but faster again for unpacking (at least on my machine). If tuples were mutable, then they wouldn't be as fast for purposes such as these.
Tuples are general-purpos...
