## forms – scenario for validation in two transmission times (the second validates and shows a previous hidden field)

I use alter_form to & # 39; user_login_form & # 39; to change. The problem is that I am hiding a field and I want to show it to the user and validate it ONLY AFTER login and passport are validated (The user previously clicked the "Login" button.)

How can I tell the form that I am not done yet and have to fill in a new field that can now be viewed and validated?

I'm not sure which approach is the best? Did someone have the same situation before

## SharePoint 2010 with REPLACE and FIND functions is executed several times in a calculated field

I am working on a SharePoint 2010 website with a field that contains three letters separated by a hyphen `e.g. AMO-SMF.`

I have created an invoice that can do that FIND and REPLACE However, there are seven different three-letter abbreviations, which I have to replace with a name. These are as follows:

``````=IF(ISERROR(FIND("AMO",Result)),Result,REPLACE(Result,FIND("AMO",Result),3,"Amosite"))

=IF(ISERROR(FIND("CRO",Result)),Result,REPLACE(Result,FIND("CRO",Result),3,"Crocidolite"))

=IF(ISERROR(FIND("CHR",Result)),Result,REPLACE(Result,FIND("CHR",Result),3,"Chrysotile"))

=IF(ISERROR(FIND("UMF",Result)),Result,REPLACE(Result,FIND("UMF",Result),3,"Unknown Mineral Fibre"))

=IF(ISERROR(FIND("ORG",Result)),Result,REPLACE(Result,FIND("ORG",Result),3,"Organic Fibre Type"))

=IF(ISERROR(FIND("SMF",Result)),Result,REPLACE(Result,FIND("SMF",Result),3,"Organic Fibre Type"))

=IF(ISERROR(FIND("NFD",Result)),Result,REPLACE(Result,FIND("NFD",Result),3,"No Fibres Detected"))
``````

Is it possible to loop in SharePoint 2010 calculated fields that covers all of these instances?

## Precise measurement of the execution times of ASP.NET Core 3.x actions (web API project)?

I want to be able to log the time spent by a particular web API action in an ASP.NET Core 3.x application.

This is a very old ASP.NET question based on global action filters, but in ASP.NET Core I think middlewares are more appropriate.

From a customer perspective, I want to measure the following time as accurately as possible:

``````Time to first byte - Time spent to send the request
``````

So I implemented the following with a slightly modified code from c-sharpcorner:

``````///
/// tries to measure request processing time
///
public class ResponseTimeMiddleware
{
private const string ResponseHeaderResponseTime = "X-Response-Time-ms";

// Handle to the next Middleware in the pipeline

///
public ResponseTimeMiddleware(RequestDelegate next)
{
_next = next;
}

///
{
// skipping measurement of non-actual work like OPTIONS
if (context.Request.Method == "OPTIONS")
return _next(context);

// Start the Timer using Stopwatch
var watch = new Stopwatch();
watch.Start();

context.Response.OnStarting(() => {
// Stop the timer information and calculate the time
watch.Stop();
var responseTimeForCompleteRequest = watch.ElapsedMilliseconds;

var logger = context.RequestServices.GetService();
string fullUrl = \$"{context.Request.Scheme}://{context.Request.Host}{context.Request.Path}{context.Request.QueryString}";
logger?.LogDebug(\$"(Performance) Request to {fullUrl} took {responseTimeForCompleteRequest} ms");

});

// Call the next delegate/middleware in the pipeline
return _next(context);
}
}
``````

Startup.cs (insert middleware)

``````public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory,
{
app.UseResponseCaching();

app.UseMiddleware();

// ...
}
``````

Is that a good approach? I am mainly interested in accuracy and do not waste server resources.

## Java – fight for the AI ​​to repeat itself an infinite number of times

I follow this as a guideline to find simple AI for an enemy since I'm new to Java.

https://www.javacodegeeks.com/2014/08/game-ai-an-introduction-to-behaviour-trees.html

https://github.com/obviam/behavior-trees/tree/master/src/net/obviam/bt

I call this function:

``````AI goombaBrain = Routines.selector(Routines.repeatInfinite(Routines.wander(Board.board, InitObject.goomba)));

InitObject.goomba.setRoutine(goombaBrain);
``````

However, once it has moved to a random location, it will not automatically reset. Any ideas? If you need more information, please let me know. (InitObject.goomba is the enemy)

## Ag.algebraic geometry – characteristic polynomial of a symmetrical \$ 8 times 8 \$ matrix with indefinite entries in relation to octonionic multiplication

I look at $$1, i, j, k, l, m, n, o$$ the standard base of the (complexed at will) octon ions ($$mathbb {O}$$ for the octon ions).
To let $$a = x_1.1 + ldots + x_8.o$$. $$b = x_9.1 + ldots + x_ {16} .o$$ and $$c = x_ {17} .1+ ldots + x_ {24} .o$$, Where $$x_1, ldots, x_ {24}$$ are indefinite about the basic field (pron $$mathbb {C}$$).

I denote by $$L_a$$ the $$8 times 8$$ Matrix that represents the left multiplication with $$a$$ in the $$mathbb {O} simeq mathbb {C} ^ 8$$ and $$R_a$$ the $$8 times 8$$ Matrix that represents the correct multiplication with $$a$$, Similar names for $$b$$ and $$c$$, I want to calculate the characteristic polynomial of the symmetric matrix:
$$S = R_a L_b L_c + {} ^ {t} (R_a L_b L_c),$$
Where $${} ^ {t} X$$ is the transpose of $$X$$,

I tried Macaulay2 and this calculation seems to go far beyond what my computer (which is supposed to be a fairly powerful portable workstation) offers.

A simple reformulation of the eigenvalue problem on a well-chosen basis (namely let $$mathbb {H}$$ be the quaternionic subalgebra of $$b$$ and $$c$$, Splits $$mathbb {O}$$ how $$mathbb {H} bigoplus mathbb {H} .e$$, Where $$e$$ is orthogonal to $$mathbb {H}$$ and take a base adapted to this decomposition) shows that:
$$(T – mathrm {Re} (( overline {b} c) overline {a})) ^ 4 textrm {divides} det (S-T.id),$$
Where $$mathrm {Re} (z)$$ is the real part of $$z in mathbb {O}$$,

I put $$f (T) = dfrac {det (S-Tid)} {(T – mathrm {Re} ((bc) overline {a}) ^ 4}$$, A variety of calculations over finite fields and specialization of the $$x_i$$ random values ​​suggests that $$f (T)$$ is indeed a square, we say $$f (T) = g (T) ^ 2$$, Where $$g$$ is a quadratic polynomial in $$T$$,

I would like a closed expression of $$g (T)$$, May it be a clean formula $$a, b$$ and $$c$$ or a dirty "in coordinates" polynomial. I would be very happy about any suggestion. I would also be interested in a theoretical argument that shows that $$f (T)$$ is indeed a square.

Many thanks!

## Why are assets (images) reported as 28 times larger in Unity Build?

I am trying to reduce a Unity WebGL build size that is currently 30 MB for the data asset. I installed the Build Report Inspector. When you click the Source Assets tab and select Size, the top entries are displayed as images. Fine. However, all sizes listed were between 4 times and 30 times the size of the file on the hard disk. Is this just a build reporter bug / artifact or a real issue I need to address to reduce build sizes?

• To edit *
Interestingly, one of the files is a text file, and the size specified by the Unity Build report is the same as that on disk …?

## How many times can a number guide an elliptic curve?

There are several upper bounds on the number of elliptic curves (e.g. over Q) to isomorphism with a given ladder N. Probably the best of Helfgott-Venkatesh of order N ^ {0.22} is given (or it may be an improvement) possible) knowledge of improved limits for 3 torsions in class groups).

My question is whether there is a lower limit? I don't know how much of this question makes sense because it feels like the most possible candidate for conducting is not a conductor. Is there a similar result?

## If the Republicans stop lying, is that the end of the party? How many times can they lie to cover up a lie and how often will the Cons?

You mean like tomorrow?

"Trump just thought people would celebrate and that would end the entire impeachment interview. Any follow-up questions?"

Yes, no … tomorrow is not good.
