Must the Wind Wall spell be vertical, or can it be angled or even curved?

Our group has two different interpretations of Wind Wall.

A wall of strong wind rises from the ground at a point you choose within range. You can make the wall up to 50 feet long, 15 feet high, and 1 foot thick. You can shape the wall in any way you choose so long as it makes one continuous path along the ground.

Interpretation 1: The wall must be vertical, and the wind blows straight upward.

Interpretation 2: The wall can be angled or even curved, as long as the wind is blowing at some upward angle, even if it’s just a few degrees above horizontal.

So, in the following diagram, is the leftmost configuration the only acceptable configuration, or do the two rightmost configurations also work?

How do I add a vertical plane in Plot3D?

I use the following code to generate a plot:

a[r_] := A  r^3/( r^3 + A^3 L1^2); Rg[r_] := (2 ma r^3)/( r^3 + 2 ma^3 L^2); \[Rho][r_] := r^2 + a[r]^2*Cos[\[Theta]]^2; \[CapitalDelta][r_] := r^2 - Rg[r] r + a[r]^2;  g = {{-(1 - (Rg[r] r)/\[Rho][r])(*G[r]*), 0,      0, -((a[r] Sin[\[Theta]]^2 r Rg[r])/\[Rho][r])}, {0, \[Rho][      r]/\[CapitalDelta][r], 0, 0}, {0, 0, \[Rho][r],      0}, {-((a[r] Sin[\[Theta]]^2 r Rg[r])/\[Rho][r]), 0, 0,      Sin[\[Theta]]^2 (r^2 + a[r]^2 + (        a[r]^2 Rg[r] r Sin[\[Theta]]^2)/\[Rho][r])}};  v1 = {Sqrt[-(g[[1, 1]] - g[[1, 4]]^2/g[[4, 4]])], 0, 0, 0} ;  (v1.g.v1) /. {A -> 6, ma -> 10, L1 -> 0.1, L -> 0.1};  Plot3D[%,{r,0,20},{\[Theta],0,Pi}] 

and I get the plot:

Now I want to add a vertical plane at r=18. How can I do that?

Best Practice for Vertical scrolling through long collapsible submenus

We’re redesigning some of our landing pages. In this case each landing page has 6-8 course categories each of which contain 3-4 courses by date, time and price. Current Layout

Each course has a CTA button and is contained under collapsible course menu. The landing page currently opens with all menus expanded, which introduces the issue of needing to scroll down a lot to find the right course. We also believe we can organize the data better.

For this we’ve come up with a floating bar at the right side which, when clicked upon, scrolls to the right course category (e.g, category 4). Propose layout

We’re wondering if there’s a better way to do this. Suggestions to improve the layout would also be welcome.

Form layout. Vertical Labels vs Horizontal Labels. Images inside

After reading http://www.lukew.com/ff/entry.asp?1502 and http://www.uxmatters.com/mt/archives/2006/07/label-placement-in-forms.php Placing labels above input fields is preferable, but if you choose to place them to the left of input fields, at least make them right aligned.

I have to design a form for a user to create customers records; I mean, a lot of fields and the user has to do this operation several times a day on his day a day.

First I use horizontal labels, centering the form on the screen enter image description here

Then I decide to use the maximum horizontal size of the screen so I went with this enter image description here

And after reading the articles I tested this enter image description here

After all, I think the 1 is the best and the 3 is the worst, what do you think? Please could you give me any advice about the layout of a form with a lot of controls and will be used by a user-worker several hours everyday.

¿Autodesplazamiento vertical en TreeView con Scrollbar?

¡Buenos días!

He colocado una scrollbar en mi TreeView con tkinter y Python 3.x

¿Es posible hacer que se desplace automáticamente conforme nuevas filas se van generando en el TreeView? ¿O debería ser el TreeView el que deba desplazarse y la Scrollbar limitarse a mostrar la posición?

Os dejo la porción de código donde creo la Scrollbar. (Se que no sigo las convenciones, poco a poco, acabo de leerlas, y ya tenia mucho escrito).

        self.chat = ttk.Treeview(             frame,             height=10,             columns=("#1", "#2", "#3"),             selectmode="none",             show="headings"             )         self.chat.heading('#1', text='Hora', anchor=tk.CENTER)         self.chat.heading("#2", text="Usuario", anchor=tk.CENTER)         self.chat.heading("#3", text="Mensaje", anchor=tk.W)         self.chat.column("#1", stretch=False, width=50)         self.chat.column("#2", stretch=False, width=80)         self.chat.column("#3", stretch=False, width=400)         self.chat.grid(row=0, column=0, columnspan=2, padx=10, pady=10, sticky="nsew")          Scrollbar = ttk.Scrollbar(frame, orient=tk.VERTICAL, command=self.chat.yview)         Scrollbar.grid(row=0, column=3, sticky="nse")         self.chat.configure(yscrollcommand=Scrollbar.set) 

Os muestro una imagen de la aplicación introducir la descripción de la imagen aquí

Debería bajar, pero permanece ahí. Muchas Gracias por su ayuda.

What is this preview pattern for vertical tabs called?

In the System Preferences on Mac OSX, the following preview pattern is shown: a list of options on the left, displayed as vertical tabs, and a preview window for every selected option. In this particular case, a video is played to clarify this option.

Mac OSX System Preferences screen

I have seen the same pattern being used on another website (Atlassian, I believe), in order to show multiple, grouped features in a way that allows for showing information very strict spacing.

Now that I would like to use a similar pattern, I’m curious to know whether these are regular vertical tabs or something else?
