color scheme – Why are all screens of SpaceX dragon control panel blue themed?

Regarding dark mode:

The researchers found significant thinning of this membrane when participants read text presented in light mode and significant thickening when reading text presented in dark mode. The thinning was more pronounced in participants who already had myopia.

This result seems to suggest that, even though performance in light mode may be better in the short term, there may be a long-term cost associated with it.

However, it may also be borrowed from aviation guidelines. In the following post, there is a discussion regarding white displays affecting night vision.

The FAA guidelines also has a brief section regarding luminance (3.2.3):

Information should be readable over a wide range of ambient illumination under all foreseeable conditions relative to the operating environment.

It’s also hard to say the displays are blue. It might be because of the angle of the photo and the composition of the display itself. There are photos where the interface appears dark grey / black. Additionally, we also don’t know if the interface has other contrast settings to perform in different light environments.

ag.algebraic geometry – For an abelian scheme, $R^pf_* Omega^q$ is locally free and its formation is compatible with any base change

Let $k$ be a field, $bar{R} to R$ a local homomorphism of artinian local rings with the residue fields $k$, $I$ its kernel, $A/R$ an abelian scheme, and $mathscr{T}$ its tangent sheaf.
Let $A_0 = A times_R k$.
Assume that $mathfrak{m}_bar{R} I = 0$.
Then $H^2(A, mathscr{T}_{A/R} otimes_R I) cong H^2(A_0, mathscr{T}_{A_0/k}) otimes_k I$?

This is a part of the proof of (2.2.4.1) of Kai-Wen Lan’s “Arithmetic Compactifications of PEL-Type Shimura Varieties”.
To show it, I need the following proposition:

Let $S$ be a scheme, $f : A to S$ an abelian scheme of relative dimension $g$.
Then the sheaf $R^pf_* Omega^q$ is locally free.
And this formation commutes with any base change.

Are there “elementary” proof of this?

I know this is (2.5.2) of Berthelot, Breen, Messing’s Théorie de Dieudonné Cristalline.
But its proof is too hard for me, since it heavily relies on the theory which I don’t know.

And I know that this post shows it elementary.
But it uses the formally smoothness and the pro-representability of the deformation of “abelian schemes + polarization”, which is I want to show using this highlighted statement.
So it is a circular reasoning for me.

How do I keep the color scheme when adding a row in the draw.io table?

In Draw.io, do the following:

  1. Under "Search Forms", type "table" and use the enter key to search.
  2. Select the first green color scheme table by selecting and
    drop on canvas.
  3. Double-click the table to bring up the "Table Object in Mockup Text" menu.
  4. Click once on a cell at the end of the table.
  5. Click the "Insert Row After" icon twice.

Enter the image description here

Note that the new cell has been added, but does not match the style of the table. How can the style of the cells be adapted to the other cells?

Configuration – configuration scheme type for array or string?

I just wrote a "complicated" one @Filter Plugin that does this:

public function process($text, $langcode) {
  return new FilterProcessResult(str_replace($this->settings('from'), $this->settings('to'), $text));
}

Now both from and to can be either an array or a string (except for the from String and to Array case doesn't make sense.) Right now I just dropped it

filter_settings.str_replace:
  type: filter
  label: 'Filter URL'
  mapping:
    from:
      type: ignore
      label: from
    to:
      type: ignore
      label: to

Is there a more specific type? Can I add a type?

Delete INFO scheme

I recently created a new database and INFORMATION_SCHEMA was there. I am aware that users should not mess around with backend services, but INFORMATION_SCHEMA has 0 bytes. I checked all the tables and there was nothing in it. Is it safe to delete INFORMATION_SCHEMA?

SharePoint 2016 search scheme – An unknown error has occurred

We have a local SharePoint 2016 farm that consists of 3 servers (application & search + wfe + database). We recently noticed that enterprise search is not working. When viewing the crawl logs from the search service application, the following error was reported and the crawl did not work:

The content processing pipeline was unable to process the item

There were comments on the internet indicating that this could be due to a problem with Manged Matadata property mappings. However, if you click the search schema in the search management, the following error appears without showing the managed properties.

An unknown error has occurred.

We tried restarting the Search Host Service and Time Service, but it didn't help.

Any assistance in solving the problem is greatly appreciated.

lisp – Encode Huffman Trees Scheme

I'm trying to write a function (codeWords t) that iterates through a Huffman tree (add # 0 if it goes left, add # 1 if it goes right …) and these values ​​in Pairing the symbol at returns a leaf along with its encoding as a string above the characters # 0 and # 1. Similar to this or trying to do so.

My original code:

(define (last l)
 (car (reverse l)))
(define (codeWords t)
  (define (helper t l)
    (cond ((null? t) l)
      ((eq? (car t) 'internal) (append (helper (caddr t) l)
                                       (helper (last t) l)))
      ((eq? (car t) 'leaf) (helper '() (cons (cons (caddr t) (cadr t)) l)))))
(helper t '()))

(codeWords (huffman (get-freq (get-count "hello"))))

I revised it after a friend's suggestion, but my sheet? Function receives an error (mcar: breach of contract
expected: mpair?
given: 1):

(define (leaf? T) (eq? (car T) 'leaf))
(define (subtree T c)
  (cond ((eq? c #) (cadr T))
    ((eq? c #1) (caddr T))))
(define (codeWords t)
 (define (helper x y)
   (if (leaf? x)
    (list (cons (value x) (reverse y)))
    (append (helper (subtree x #)
                    (cons # y))
            (helper (subtree x #1)
                    (cons #1 y)))))
  (helper t '()))

I also came up with this code that seems to work but doesn't pass my test cases:

(define (codeWords t)
 (define (encode char tree)
   (cond
     ((null? tree) t)
     ((eq? (caar tree) char) '())
     (else
      (let ((left (encode char (cadr tree))) (right (encode char (caddr tree))))
        (cond
          ((not (or left right)) #f)
          (left (cons # left))
          (right (cons #1 right)))))))
 (encode t '()))

I think there is probably a solution without having to make a hand? Function with Eq. and & # 39; scroll as in my original code or try to implement something like the encoding function here, but I am currently writer's block.

Scheme – Moving race data from one line to another line

SQL beginners here. In my race data, I have teams with several lines that show race data per run.
I would like to summarize the data of each team in one line as follows:

Enter the image description here

to

Enter the image description here

I'm not sure how to go through these duplicates in the "Team" column, move them all for each team, and put them all in one row. Or is it better to create a new table for each team?

Thanks for your time.

Is there a URL scheme for prefilling fields in a ZenDesk ticket form?

In certain circumstances, we may want to pre-fill the subject line field of a ZenDesk ticket form mailto: Links optionally accept a subject line. The use case here is to perform easy ticket routing based on the subject line. Is it possible to pre-fill fields in a ZenDesk ticket form using URL parameters?

Thank you for reading!

Database design – is this a pattern or can I improve this scheme?

I have inherited a MySQL 5.6 database that I want to optimize in terms of structure and speed.

Brief background: users send their daily time records for the day through an application that is sent to a spreadsheet timeentry, but can use the same form in the application to submit expenses that go to a spreadsheet expenseentry. Both timeentry and and expenseentry have triggers after pasting that insert a copy of their row into a table lineitemswith a column that records which row comes from which table – a column type which is 1 if it came from timeentry and 2 if it came from expenseentry. In addition, timeentry and expenseentry have triggers after the update to keep the columns in lineitems updated to the current values.

This lineitems The table is then used to map it to other business units in the database, sales orders, orders, etc., but based on it id Column, not the fk_itemId Field that has both timeentry and expenseentry IDs are included, so there are some duplicate entries due to the ID overlap between the two tables.

I was asked to allow the assignment of the data from the timeentry Table to a new business unit and saw that things are currently structured in our database. Is this a general pattern? Or would it be better to create these assignment tables directly from sales orders / orders etc.? timeentry and expenseentry directly instead of through the table lineitems. I can see how lineitems is useful for some queries, but the viewing was structured, it was not intuitive for me and makes me think that there could be a better way.
