Prevent multiple application instances after Windows restarts
Windows 10 - disable reopening programs after restart/startup
Adjectives and nouns to describe an answer that doesn't answer the question? How exactly using VB6 can I can call any Windows shell command as you would from the command-line?  For example, something as trivial as:  echo foo Don't heavier objects actually fall faster because they exert their own gravity? How to stop the find command after second match? How to make find command, that will show only first two matches and then end, something similiar to  just version for two records. Blender 2.8 : python code to switch shading mode (between wireframe and solid mode) If i switch between solid and wireframe mode, i can see in the info window that these commands are invoked :  bpy.data.screens["Layout"].shading.type = 'WIREFRAME' bpy.data.screens["Layout"].shading.type = 'SOLID'   Now i want to execute this command using python console. So i cut and paste the codes into python console but i got this error :   &gt;&gt;&gt; bpy.data.screens["Layout"].shading.type = 'WIREFRAME' Traceback (most recent call last):   File "&lt;blender_console&gt;", line 1, in &lt;module&gt; AttributeError: 'Screen' object has no attribute 'shading'  &gt;&gt;&gt; bpy.data.screens["Layout"].shading.type = 'SOLID' Traceback (most recent call last):   File "&lt;blender_console&gt;", line 1, in &lt;module&gt; AttributeError: 'Screen' object has no attribute 'shading'   Does anyone know why ? and what the correct script should i use in python console ?  Thanks How do I install an older version of an app on an iPhone? zsh scripting - How do I NOT match a pattern in filename generation? I need to find limit points of the set $\{  \frac{1}{n} +\frac{1}{m} \mid n, m = 1,2,3,\dots \}$.  My try :   If both $m$ and $n$ tend to very large values say $\infty$ then the value of $\{ \frac{1}{n} +\frac{1}{m} \}$ tends to $0$, and if only one of $m$ or $n$ tends to very large values, then the set $\{ \frac{1}{n} \mid n=1,2,3,\dots\} $ acts as limit points.   So is it true that a set of limit points is $\{0\}$ $\cup$  $\{\frac{1}{k} \mid k=1,2,3,\dots \}$?  How should I write this proof rigorously? Number agreement between subject and object Title says it all, I don't see confirmation in  and a cursory google search seemed to say assume no and speculate about the pokemon bank. A 2D game called Deer Hunter has projectiles like this:    Are the projectiles 2D or 3D models? How could I implement something similar? How should duplicate questions be handled? What should I do when I see a question that is a duplicate of another one?   Should I answer it? Should I downvote it? Should I comment? Should I edit the question to indicate it's a duplicate? If I can, should I (vote to) close the question? What happens when I vote to close as duplicate? Or: Why did a comment with my name on it just appear? Should I flag it for moderator attention? What about similar or related questions? I start with knowing that two numbers are coprime if:  $n*k + m*j = 1$  So, setting $k = a$ and j = $a+1$ I can solve as follows:  $n*a + m*a + a$  Then,  $a(n+m) + m = 1$  Where can I go from here? I need a P&amp;S camera for my family. They would probably use it for family functions,trips etc. I want a camera with flash for taking good night photos with a decent quality. They are not technically inclined and I dont want much manual features apart from the normal modes (potrait,sports,landscapes). Decent picture quality for normal conditions is the criteria I am looking for. If the camera looks little big, it is an added advantage.  I have looked at few models like Fujifilm Fine Pix F800 EXR, the Panasonic Lumix DMC series and a Nikon P510. But I am confused with all the options and the different reviews on different sites. My thinking is that for a point and shoot camera, it is better to consider brands other than Nikon and Canon since they may provide better value for money.   Can someone recommend some good resources for analysis and what kinds of cameras I should consider - a bridge camera, a basic point and shoot, or some other type? What is the net charge of the Earth? Why is electric field lines away from (+) and toward (-)? I have a questions about the electric field lines.   Well in the basic learning, we know that:   The electric field lines extend away from a positive charge They move forward a negative charge   Let's take parallel plates, which make a uniform electric field.If we take the basic learning, which I mentioned, in accounts, it's very easy to understand that this is the direction of a positive charge object if we put the object between the plate (move away the positive charged plate and toward negatively charged plate).  The problem is if we put a negative charged object between. Isn't the electric field reversed ? Bounding box is larger than expected when drawing a curved path I have been working on logo for my department and I have the following code. The problem is that whenever I compile the diagram seems to be larger than the actual logo. I do not know what is the problem. I know the numbers I have selected are not the best but any insights into the matter will be highly appreciated.   \documentclass[letterpaper]{article}  \usepackage[top=2cm,bottom=2cm,left=2cm,right=2cm]{geometry}  %\usepackage{amsmath,amssymb,units}  %\usepackage{enumitem,multicol}  \usepackage{tikz}  %\usetikzlibrary{arrows}  \usepackage{lipsum}   \begin{document}   \lipsum[1-2]  \begin{tikzpicture}[y=0.80pt, x=0.8pt,yscale=-1]  \path[draw=black,fill=white]    (258.9527,290.5199) .. controls (173.9885,538.4766) and (568.5860,261.2969) ..

I want to build an uncountable well-ordered set within the theory $Z^\textbf-$. So, I take $A=\omega$ (exists by infinity axiom) and define $$W:=\{(X,R)\in\mathcal{P}(A)\times\mathcal{P}(A\times A):\langle X,R\rangle\ \text{is a well-ordered set}\}$$  With this I consider the set $T:=W/\cong$ (where $\cong$ is isomorphism relation). Note that $W$ and $T$ are sets by power set axiom. So I define for each equivalence class $[x],[y]\in T$ the order  $$ [x]\leq_T[y]\Leftrightarrow \text{type}(x, R_x)\leq \text{type}(y,R_y) $$  Here, $R_x$ means the order of $x$ that make it belongs to $[x]$.   So, $T$ is well ordered by $\leq_T$ and it is uncountable.  Question: I don't pretty sure if I can build $\leq_ T$ without replacement axiom. Another doubt is, Can I take the $R_x$ without AC? I used a  for Photoshop, and was able to create some boxes with it. These boxes were shaped in the form of Software Boxes, while I require Customized Dimensions Boxes, which currently I'm trying to create with .   This software creates a box with no Reflection, and I disabled shadows in it, cause it doesn't allow transparency while saving to png. It allows custom dimensions, rotation, etc settings, but doesn't save transparency or reflections.  Here's the difference in output from both the above mentioned apps.. I'm trying to get the reflection + shadow in the 3D box Generator to the Protomissume generated image.   My question: How can I create similar Reflection &amp; Shadow in Photoshop?   Images:  3D Box Generator   Protomissume Box Shot   Thanks for any help.  Here are the Box Shot images (Photoshop, Protomissume) :  [  ] Story about workers repeatedly doing trivial work I'm trying to remember a (short) story I read in school some time ago. I don't have much, but here it is:   Numbers of workers are assigned to trivial task, like changing broken lightbulbs (or something similar). Once they finished their daily work, another group of workers are putting the broken lightbulbs in again, allowing for an endless, trivlal working circle.   I know that isn't much, but maybe someone has an idea, thanks.
