focal length – How can I calculate a camera sensors width and height?

I try to compute the focal length for different field of views of a camera.

Therefore I need the sensor size horizontally and vertically, but in the datasheet I only have the information: 1/3" 2.4 MP Image Sensor.
The image size is 1920x1080 it that’s needed.

How do I get the size of the size of the sensor?

Thanks

SPFx: Min Width headers SharePoint Document Library web part SharePoint Online

I am new to spfx but not to SharePoint. Has anyone been able to get min width to work for headers for all users in a Document Library view web part? I need to show all documents from a view and need the ability to filter a Category field but have the requirement for the headers to stay a certain width or at least not be smaller than a certain width for ALL users. As most are aware, even using JSON to set the min width when formatting a view doesn’t work for all users. I see the width as it was set but another user sees the width smaller than the mid width set. Is there anything through PnP SPFx that I am not finding? What I need is a forms repository view (library) with the Category field filterable on the top page of the site but with the headers at a min width of 1000 px for everyone. Any help is very much appreciated.

photoshop – Is changing of width and height of smart object image by using free transform OR resizing of the image the same things?

I’m not very good in Photoshop tools, can someone help me to understand;

Is changing of width and height of smart object image by using free transform, OR resizing the image, the same thing?

If I change the width and height of smart object image with free transform in Photoshop will it automatically rebuild the image with a new number of pixels just like if I resize the image with the resize image function in Photoshop?

html – not able to get full page width using elementor and hello theme

Front page

Please look at the page above and notice the huge empty columns on either side the page . How can I remove them ?

Problem in detail :

I am using elementor’s “Hello” theme . While creating a page using elementor, I select “Elementor canvas” as page layout . Then under structure, I select the structure shown in the image below ( the one that is darker than the other available options)

enter image description here

I, then, add a section on this page and set, “Content width” to “Full width” and Stretch section to “Yes” as shown in the image below :

enter image description here

Then, I add the html widget inside this section and type html code inside it . The html code that I have typed can be seen here :

https://docs.google.com/document/d/1NjVakoFPleuHuKcQvFB1GeEoZ5crlY496fWeKc9YeMs/edit?usp=sharing

This html code when run elsewhere, results in a full width html page. But this same html code is resulting in blank columns. What can be done to rectify this ?

python – Plotly candlestick chart – Candle width is not correct

I try to print stock charts with Plotly. It is working so far quite well. But now I recognized that the width of the candles is not correct. They are, in my case, all ’15 minutes’. So they should be next to each other, without gap. But there is space between them. So they are not shown in the correct place. You can see it on the picture. The candle I hover with the mouse is 9:02 till 9:16… and look at which place on the x-axis it is. From about 8:58 – 9:05.
The real problem about it is that I draw also these buy/sell points in the chart. They should be on the exact point on the candlestick… but as they are not in the right place… it doesn’t fit at all.

How to draw the width of the candlesticks correctly?

Fixing macOS Big Sur Finder SIDEBAR width prefs from command line?

My default sidebar width in Big Sur is too small. While I can click/drag to make folders look wider, that fix only works for folders that I open. If any application calls a new window to open – say for picking a file to attach or upload – the default windows that open render differently and my sidebar shortcuts once again can’t be fully seen.

When I drill down into those prefs via CLI to change them, there seem to be about a dozen places in the finder’s preferences file that mention the sidebar width:

defaults read com.apple.finder | grep SidebarWidth
        SidebarWidth = 174;
        SidebarWidth = 221;
        SidebarWidth = 221;
    "FK_SidebarWidth" = 294;
            SidebarWidthTenElevenOrLater = 217;
    NSNavSidebarWidth = 120;
        SidebarWidth = 178;
    SidebarWidth = 260;
        SidebarWidth = 135;
                SidebarWidth = 248;
            SidebarWidth = 0;
        SidebarWidth = 221;

I’ll spare sharing the entire Finder preferences file as it’s ginormous, sooo: I have questions!

  1. Am I working with the right preference file?
  2. Which of these mentions is the right one?

Thanks, all.

discrete geometry – ‘Fattest’ Polygons based on Diameter and ‘Least Width’

Definitions: The diameter of a convex region is the greatest distance between any pair of points in the region. The least width of a 2D convex region can be defined as the least distance between any pair of parallel lines that touch the region. Let us refer to a polygon as ‘fat’ if the ratio between its diameter and least width (call this the ‘thinness ratio’) is low.

General Question: Given a general n, which n-gon is the fattest? For which values of n (if at all) is the fattest n-gon a regular n-gon?

2 Special cases:
-For n =3, the equilateral triangle is the fattest. The thinness ratio is 2/sqrt(3).

-For n = 4, the square is not the fattest – its thinness ratio is sqrt(2). Numerically, trapezium with base 1 unit and upper edge nearly 1.046 and both base angles equal and thinness ratio nearly 1.2 seems to the the fattest quadrilateral.
