So the other day - for weeks on and off actually - I've been struggling with error recovery in the LALR(1) parsing algorithm.
Eventually - and i hated doing it - I decided to eliminate the feature, and give up.
Now, I sleep easier. This isn't gnawing at me anymore and I'm satisfied with my decision, despite being so angsty about making it.
It's like housecleaning where you get rid of a bunch of stuff you think you need, but it is just clutter. After the fact it feels really good.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

Then a week later you say, "where did I put that? It's got to be here somewhere..."

I have like 3 prior iterations of a LALR(1) parser that each have their attempt at it. I'm a packrat. I don't throw code away.

Agave some thought and I would certainly aloe that.

You know the one...it's bundled with Windows 10.
It sure is pretty. I particularly like the hourly forecast breakdown which, for today, for each hour, says there's 0% of chance of rain. Literally, 0%, 0%, 0%, [...] %0, as far as it'll go (7am tomorrow morning).
This is neatly summarized with a single "Precipitation" graph, just under the hourly breakdown. This one says 30%.
If there's 0% chance of rain every hour until nearly 24 hours from now...how does this add up to "30% chance of rain"?
This is not a new thing. This app's been showing this sort of thing forever, as far as I can tell. Would love to see the source for that.

I wouldn't know. Living in Wales means it just predicts rain all the time, and is generally spot on.

More than likely it is just pulling data from some other site/location, rather than trying to do all of the "calculations" itself.

It's not just the Win10 app that that happens on. I've seen it in Accuweather as well.
As someone else said, it's probably from a different dataset.

Dumb thing to do when your datasets contradict one another.
It's like having two watches that aren't synchronized. You start questioning the accuracy for both.

I understand your point. I've learned to live with it I guess.
If you zoom out and look at it, there's a 30% chance of rain throughout the day at some point (based on historical records and current conditions) but when zoomed in to specific hours there isn't enough.
Or perhaps they round down. Maybe the actual computer model is 4% every hour or something.
I don't necessarily disagree with you; however, I do understand the complexity of it, I think.

I upset them when I informed them that winds come from a compass bearing, not go to it, so their vanes were out by 180 degrees.
In typical ms fashion, rather than fix it (which would probably take ten minutes), they removed the vanes (which probably took an hour).

WTF?
I wrote a simple test in the Startup because I was to lazy to write a unit test. Part of writing the test is that I added the first non-generic constructor in the DB context definition:
public CatalogContext(DbContextOptions options) : base(options)
{
}
public CatalogContext(DbContextOptions<CatalogContext> options) : base(options)
{
}
Did my test, figured out how to work around the stupid EF issue, then removed my test code. And discovered that all my endpoints return "Unauthorized." WTF? Comment out that first non-generic constructor and lo-and-behold, API's work again.
WTF??? I set a breakpoint on the constructor and it doesn't even get called?
And then there's the whole IServiceCollection debacle. Whowever wrote a a service manager where you can't get the service? So you write:
services.AddDbContext...
and you'd think there might be a
services.GetDbContext... call, right? Nope! Because they rely 100% on dependency injection. Oh for F*** sake.
And then there's db.YourContextObject.FromSql, because there isn't any SqlQuery because of Linq compatability issues. And FromSql has such absurd constraints that it basically is useless.
Read more:
Database.SqlQuery<TElement> Missing · Issue #10365 · aspnet/EntityFrameworkCore · GitHub[^]
and:
Leveraging Raw SQL in Entity Framework Core -- Visual Studio Magazine[^]
So instead I found GitHub - devel0/netcore-ef-util: net core entity framework util[^]
I despise:
* dependency injection
* EF
* Behind the scenes magic is breaks everything if you don't wave the wand just exactly right
While I like .NET Core, I just refuse to use the ASP.NET/EF pieces.
And don't even get me started on the BS on how to get CORS working properly and the whole pipeline-middlewear crapola. More perfect wand waving and incantations required.

We had a mismatch during development where a new column existed in DEV but not yet in TEST. No matter, we weren't using it in this test so our filter didn't use it, no problem. Except EF generated SQL to ignore it by referencing it! Boom! 
Straight SQL worked fine, of course. 
- I would love to change the world, but they won’t give me the source code.

If your solution uses DI and you create ambiguous constructors then the only possibly outcome is failure. That's not a failure of DI, it is you using it in ways it is not intended to work. You can't throw a bike off a cliff and complain it didn't float to the ground.
As for getting services you've added to the service collection you use IServiceProvider to do that, the service collection is exactly what it says, a collection of services. If you want a given service you get it from the service provider.
As for EF and direct\raw SQL etc, EF is an ORM, if need to use raw sql, stored procs etc then it is the wrong tool for the job.
So use the right tool for the right job, and use those tools as they are intended to be used and you'll be fine.

Pardon me for taking exception to this, but that's BS. I've written DI's and you go for the most specific instantiator you can with the information you have in the service manager. You don't go from general to specific, or simply barf in the bowels of your injector with no intelligible message.
F-ES Sitecore wrote: As for getting services you've added to the service collection you use IServiceProvider to do that
Right. So you have one thing for adding services, but another thing for getting them? BS.
F-ES Sitecore wrote: As for EF and direct\raw SQL etc, EF is an ORM, if need to use raw sql, stored procs etc then it is the wrong tool for the job.
And exactly why can't the tool do both gracefully? It's not the wrong tool. The tool is broken.
We have very different views, I see!
