Declaring variables inside a struct in c
Why can't we initialize members inside a structure?
Cloning a Non-Standard Svn Repository with Git-Svn How do I add myself back as a sudo user? I am using this IC in boost converter configuration :   It steps up the voltage from 16.5V to 23V.   It drives a load current of 270mA.  I need to calculate the input current of the converter.   I understand that output power/input power is efficiency.   Since I know the output power, can I take the efficiency value from the graph 21 of the attached datasheet (86.8% approx - obtained from fig 21 graph) and find the input power?   With the input power, and since I know the input voltage, I can calculate the input current.   Is this the right way?   And I want to check if all the components at the output of the IC are properly rated.   Which parameters and components should I check and how to check?    Sorry for the poor image quality. The two transistors are taken from the SWE pin. How do I change the plymouth bootscreen? With regards to Plymouth --  Are there alternative boot screens available?  What's the easiest way to change the boot screen? I am currently in a clan with three members. When we tried to initiate a clan war it said we had insufficient clan requirements. Does anyone know what the full requirements are? Is there a minimum clan member requirement? Variable parameters in C# Lambda Intuition for multiple temporal dimensions It’s easy, relatively speaking, to develop an intuition for higher spatial dimensions, usually by induction on familiar lower-dimensional spaces. But I’m having difficulty envisioning a universe with multiple dimensions of time. Even if such a thing may not be real or possible, it seems like a good intellectual exercise. Can anyone offer an illustrative example? no cycles if and only if has $n-m$ connected components CUDA Driver API vs. CUDA runtime Show that an integer of the form $8k + 7$ cannot be written as the sum of three squares. I have figured out a (long, and tedious) way to do it. But I was wondering if there is some sort of direct correlation or another path that I completely missed.  My attempt at the program was as follows:   A number of the form, $8k + 7 = 7 (mod 8)$. That is, we are looking for integers a, b, c such that $a^2 + b^2 + c^2 = 7 (mod 8)$.   LONG and TEDIOUS way: $$(8k)^2 = 0 (mod 8)$$ $$(8k+1)^2 = 1 (mod 8)$$ $$(8k+2)^2 = 4 (mod 8)$$ $$(8k+3)^2 = 1 (mod 8)$$ $$(8k+4)^2 = 0 (mod 8)$$ $$(8k+5)^2 = 1 (mod 8)$$ $$(8k+6)^2 = 4 (mod 8)$$ $$(8k+7)^2 = 1 (mod 8)$$  That is, using three of these modulo there is no way to arrive at  $$a^2 + b^2 + c^2 = 7 (mod 8)$$ Parameterize an SQL IN clause Does Find My Mac stop working after the system has been wiped? Nautilus does not show the left bar, how do I turn it back on? When I open nautilus does not open the left bar where it says computer and down markers such as music, documents, videos, downloads. I reinstalled nautilus from the synaptic package manager but nothing happened. What I can do to make that bar visible again? Starting a new online business I have just started to work on an online business mode website. My dream is to make it live and bring revenue from the website. However, the project is in Incubator phase.   In this situation, can i register it as a Business, Open a Business Bank Account and start making the Purchases such as Servers, Software's etc.  Whether i have to pay Tax for my start up business ?  Location : New Jersey, US A function takes every function value twice - proof it is not continuous I want to prove the following nice statement I've found:  A function $f: [0,1] \rightarrow \mathbb{R}$ takes every function value twice - proof it is not continuous  I've already found an answer to my question but one thing is still not clear to my mind. The answer I found was :   Whole post:  "Assume that you have a function $f$ that does take every real value exactly twice. Let $f(a) = f(b) = 0$ with $a &lt; b$. Let $c \in (a,b)$ be given, and assume without loss of generality $f(c) &gt; 0$. Then for every $0 &lt; \epsilon &lt; f(c)$ there exist $d \in (a,c)$ and $e \in (c,b)$ such that $f(d) = f(e) = \epsilon$. So on the intervals $[0,a)$ and $(b,1]$ our function cannot go any higher than zero. That means that $f$ should take every positive real value on the interval $[a,b]$. However the restriction of $f$ to $[a,b]$ is continuous from a closed interval to $\mathbb{R}$ and thus bounded. Contradiction."  Now everything is clear here except for:  "However the restriction of $f$ to $[a,b]$ is continuous from a closed interval to $\mathbb{R}$ and thus bounded. Contradiction."  Well I think know what Arthur is telling there: Because of the boundary there is always at least one function value that can't be taken twice by the function, e.g. just like the peak of $-x^2$.  But that is exactly where I was stuck before I started researching that issue. Is it really possible to just say it the way Arthur did? I thought that I'd have to further somehow prove the statement that boundary leads to that contradiction.    I hope that it is clear what I was trying to express here...  Anyways as always - thank you for your help!  FunkyPeanut How to run Java code using Java code? How to create animated GIF images of a screencast? I've seen animated GIF images of screen casts (like the one below) promoted a few times on this site as a way to improve answers.    What toolchain is being used to create these? Is there a program that does this automagically, or are people taking screencasts, converting them into a series of static frames, and then creating the GIF images?
