Do you think it is okay for someone who is black to say that all white men are bad?
|
Making a blanket statement about a large group of people is racist. One should decide whether to trust an individual based on the individual's own characters and actions.

Why aren't democrats building a big beautiful wall across our borders?
|
It's not clear to me that Democrats are opposed to border-wall construction (your one source suggests they are fine with border walls/fences where necessary), so much as they opposed to some of the plans for full-border walls that have been put forth so far.
Recently, in response to reports that the spending bill would include funding for a border wall, 5 Democratic senators released a letter voicing concerns over the cost, the effectiveness, and the legal issues of constructing it.
We are also concerned with reports that there may be an effort to include funding for a very expensive new wall along the southern border with Mexico and a “deportation force.” According to non-partisan experts, the proposed new border wall could cost as much as $25 million per mile and raises considerable issues that have not been resolved by the Congress or the Department of Homeland Security. First, many experts believe that such a border wall will not work. Second, there is real concern that the Administration, put simply, has no plan to build the border wall. For example, the Administration has not detailed how to 1) use eminent domain and other procedures to acquire land from private landowners and Native American tribes, 2) design the wall, 3) locate the wall, 4) construct the wall, and 5) require Mexico to pay for the wall given the President’s clear and repeated promises that he would force Mexico to do so. Finally, there are objections to the construction of a wall from Democratic and Republican members of Congress that represent border states. Given these and other concerns, we believe it would be inappropriate to insist on the inclusion of such funding in a must-pass appropriations bill that is needed for the Republican majority in control of the Congress to avert a government shutdown so early in President Trump’s Administration.

Senator Charles Schumer
Senator Richard Durbin
Senator Patty Murray
Senator Debbie Stabenow
Senator Patrick Leahy
Based on this letter, it appears their main objections to a full border wall are currently the cost-benefit ratio and the legal issues of taking land from Americans to build it on; objections that may not be unique to Democrats.

I want to create an Entity Framework Core model that has indexing and unique constraints added to certain fields through the Fluent Api. What's the best way of doing this?
|
Currently there is no "first class support" for creating a index via the fluent API, but what you can do is via the fluent API you can mark properties as having attributes from the Annotation API. This will allow you to add the ```Index``` attribute via a fluent interface.
Here are some examples from the work item from Issues site for EF.
Create a index on a single column:
```modelBuilder.Entity()
.Property(e => e.MyProperty)
.HasColumnAnnotation(
IndexAnnotation.AnnotationName,
new IndexAnnotation(new IndexAttribute()));
```
Multiple indexes on a single column:
```modelBuilder.Entity()
.Property(e => e.MyProperty)
.HasColumnAnnotation(
IndexAnnotation.AnnotationName,
new IndexAnnotation(new[]
{
new IndexAttribute("Index1"),
new IndexAttribute("Index2") { IsUnique = true }
}));
```
Multi-Column indexes:
```modelBuilder.Entity()
.Property(e => e.MyProperty1)
.HasColumnAnnotation(
IndexAnnotation.AnnotationName,
new IndexAnnotation(new IndexAttribute("MyIndex", 1)));
modelBuilder.Entity()
.Property(e => e.MyProperty2)
.HasColumnAnnotation(
IndexAnnotation.AnnotationName,
new IndexAnnotation(new IndexAttribute("MyIndex", 2)));
```
Using the above techniques will cause ```.CreateIndex()``` calls to be automatically created for you in your ```Up()``` function when you scaffold your next migration (or be automatically created in the database if you are not using migrations).

Write me a short code that can be used for drawing arcs using TikZ.
|
```\draw (x,y) arc (start:stop:radius);``` draws an arc
* with radius ```radius```
* starts from ```(x,y)```
* with center ```(x-r*cos(start), y-r*sin(start))``` and
* ends at ```(x-r*cos(start)+r*cos(stop), y-r*sin(start)+r*sin(stop))```.
For example,
``` \draw[red] (0,0) arc (30:60:3);
```
draws an arc
* of radius ```3```
* starting from ```(0,0)```
* with center ```(0-3*cos(30),0-3*sin(30))``` and
* ending at ```(0-3*cos(30)+3*cos(60),0-3*sin(30)+3*sin(60))```.
```\draw[blue] (0,0) -- ++(30+180:3) -- +(60:3);
```
draw a blue line to the arc to make a complete sector.
Minimal Working Example
```\documentclass[tikz,border=12pt]{standalone}
\begin{document}
\foreach \start/\stop in {30/60,45/90,135/180,0/180,45/315}
{
\begin{tikzpicture}
\draw[lightgray,ultra thin] (-6,-6) grid (6,6);
\draw[red] (0,0) arc (\start:\stop:3);
\draw[blue] (0,0) -- ++(\start+180:3) -- +(\stop:3);
\node[anchor=north] at (0,6) {$(\start:\stop:3)$};
\end{tikzpicture}
}
\end{document}
```
