underpass | An efficient , secure localtunnel clone | Cryptography library

I have a DB table name is the product. when I query (eloquent) to that table return collection object with all the fields. but I access the banner_image field every time return a null value. but I can access the other variables in that collection working fine. If I Defining An Accessor, the issue is solved. I want to know about, whats the issue only for one variable.

DD to eloquent collection

I am working on creating a form to send a styled email, everything worked fine until I started to add IDs to my html elements inside of my php variable. Is there a reason this does not work? I have tested the html code and it works fine on its own, but when put into a php variable, the page will not run. I looked at a few other posts and they said to just add IDs like I have, but it does not work. Any ideas why?

I have a question not on spatstat but on use and limitation of spatsat.

During the calculation of metrics like pcf and k function equivalents on linear networks, a shortest path distance is used instead of euclidean distance. I have the spatsat book from 2015 and I remember reading somewhere in the text that the shortest path calculation on networks is not sensitive to grade separations like flyover, bridges, underpass and therefore caution should be exercised in selecting the study area or be aware of this limitation while interpreting results.

Is there any publication that discusses this limitation of grade separation in detail and may be suggesting some workarounds? Or limitations of network equivalents in general?

Thank you

At the moment I'm working on a project with point pattern events on a linear network (car crashes) and I'm reading chapter 17 of spatstat book: "Spatial Point Patterns: Methodology and Applications with R".

The authors of the book explain that they defined a new class of objects called lpp for analyzing point patterns on a linear network. The skeleton of each lpp object is a linnet object and there are several functions to create a linnet object. For my application the relevant functions are linnet and as.linnet. The function linnet creates a linear network object from the spatial location of each vertex and information about which vertices are joined by an edge, while the as.linnet function can be applied to a psp object which is transformed into linnet objects inferring the connectivity of the network using a specified distance threshold.

The reason why I'm asking this question is that I don't know how to efficiently create a linnet object starting from a sf object with a LINESTRING geometry. As far as I know, it's possible to transform the sf object into an sp object (i.e. a SpatialLines object), then I can transform the sp object into a psp object (using as.psp function) and then I can transform the psp object into a linnet object using the as.psp.linnet function (which is defined in the maptools package). The main problem with this approach (as the authors of the package said in their book) is that the inferred network is wrong every time an overpass or an underpass occurs in my network data since the corresponding linnet will create artificial intersections in the nework. Moreover, as the authors said in their book, the code gets exponentially slower.

The following code is a simplified version of what I did so far but I think that there must be an easier and better way to create a linnet object from an sf object. I would use the linnet function but the problem is that I don't know how to create a (sparse) adjacency matrix for the corresponding vertices of the network or a matrix of links between the edges of the network.

I have a model called Location and am trying to get a specific entity: /api/location/2

When I do that, I get the result for the record with ID of 2, but also an extra record:

I am trying to pass some row data from a list to next screen to display details but cannot seem to achieve it. This is how i pass props when navigating like:

I have started learning react-native, awesome stuff. I have been able to use StackNavigator to navigate between screens.

On one screen I display a list populated from a static json file. On clicking one row, the next screen is supposed to pop up with details of the selected item. Any help will be appreciated. I have created a gist with all the relevant classes https://gist.github.com/SteveKamau72/f04b0a3dca03a87d604fe73767941bf2

I am using following mongo db query . and it is showing me only age groups of my personas data.
